    Full Text Available Abstract Background The Australian Longitudinal Study on Male Health (Ten to Men was established in 2011 to build the evidence base on male health to inform policy and program development. Methods Ten to Men is a national longitudinal study with a stratified multi-stage cluster random sample design and oversampling in rural and regional areas. Household recruitment was conducted from October 2013 to July 2014. Males who were aged 10 to 55 years residing in private dwellings were eligible to participate. Data were collected via self-completion paper questionnaires (participants aged 15 to 55 and by computer-assisted personal interview (boys aged 10 to 14. Household and proxy health data for boys were collected from a parent via a self-completion paper-based questionnaire. Questions covered socio-demographics, health status, mental health and wellbeing, health behaviours, social determinants, and health knowledge and service use. Results A cohort of 15,988 males aged between 10 and 55 years was recruited representing a response fraction of 35 %. Conclusion Ten to Men is a unique resource for investigating male health and wellbeing. Wave 1 data are available for approved research projects.

    This article used data from 5,171 young women participating in the Australian Longitudinal Study on Women's Health, a nationally representative longitudinal cohort study, to identify longitudinal trajectory patterns of mental health across 6 surveys over 16 years of early adulthood, from age 18-23 to age 34-39. In addition, we identified both…

    Recruitment and retention of participants to large-scale, longitudinal studies can be a challenge, particularly when trying to target young women. Qualitative inquiries with members of the target population can prove valuable in assisting with the development of effective recruiting techniques. Researchers in the current study made use of focus group methodology to identify how to encourage young women aged 18-23 to participate in a national cohort online survey. Our objectives were to gain insight into how to encourage young women to participate in a large-scale, longitudinal health survey, as well as to evaluate the survey instrument and mode of administration. The Australian Longitudinal Study on Women's Health used focus group methodology to learn how to encourage young women to participate in a large-scale, longitudinal Web-based health survey and to evaluate the survey instrument and mode of administration. Nineteen groups, involving 75 women aged 18-23 years, were held in remote, regional, and urban areas of New South Wales and Queensland. Focus groups were held in 2 stages, with discussions lasting from 19 minutes to over 1 hour. The focus groups allowed concord to be reached regarding survey promotion using social media, why personal information was needed, strategies to ensure confidentiality, how best to ask sensitive questions, and survey design for ease of completion. Recruitment into the focus groups proved difficult: the groups varied in size between 1 and 8 participants, with the majority conducted with 2 participants. Intense recruitment efforts and variation in final focus group numbers highlights the "hard to reach" character of young women. However, the benefits of conducting focus group discussions as a preparatory stage to the recruitment of a large cohort for a longitudinal Web-based health survey were upheld.

  4. A Longitudinal Study of ISP Reactions to Australian Internet Content Regulation Laws

    Full Text Available This paper discusses a longitudinal study which surveys a targeted selection of Australian ISPs to determine both initial and subsequent effects of and attitudes towards the legislation. The paper observes that, initially, ISPs were generally opposed to the legislation, offering stiff opposition to its introduction. The initial results suggested dissatisfaction with the legislation on the part of ISPs, and foreshadowed adverse effects on the online industry. Concerns were also raised that the legislation would not be effective. Two years later, however, ISPs had generally observed little change in operations, arguing that the legislation had had little overall effect. The study also raises a number of interesting issues that are outside the scope of this paper. These issues merit further research.

    2017-11-01

    International research suggests that early mathematical competence predicts later mathematical achievement. In this article, we explore the relationship between mathematical competencies at 4-5 years, as measured by teacher ratings, and later results on Years 3, 5, 7 and 9 National Assessment Program - Literacy and Numeracy (NAPLAN) numeracy tests. Data from a nationally representative sample of 2343 children participating in the Longitudinal Study of Australian Children (LSAC) are examined. In line with international studies, we report moderate correlations between preschool-entry mathematics and later NAPLAN numeracy test results. However, analysis of individual growth trajectories indicates that early mathematics predicts the initial (Year 3) level, but not subsequent growth. This suggests that early mathematical competencies are important for enhancing achievement in early schooling, but that the quality of mathematics education provided in the schooling years is critical for future development.

    Full Text Available Worldwide, dietary supplement use among reproductive aged women is becoming increasingly common. The aim of this study was to investigate dietary supplement use among Australian women during preconception. Self-reported data were collected prospectively for the Australian Longitudinal Study on Women’s Health (ALSWH. The sample included 485 women aged 31–36 years, with supplement data, classified as preconception when completing Survey 5 of the ALSWH in 2009. Frequency and contingency tables were calculated and Pearson’s chi-square test for associations between demographic variables and supplementation status was performed. Sixty-three per cent of women were taking at least one dietary supplement during preconception. Multiple-micronutrient supplements were the most commonly reported supplement (44%. Supplements containing folic acid and iodine were reported by 51% and 37% of preconception women, respectively. Folic acid (13%, omega-3 fatty acids (11%, vitamin C (7%, B vitamins (4%, iron (3%, and calcium (3% were the most common single nutrients supplemented during preconception. Women trying to conceive, with no previous children, and born outside Australia were more likely to take dietary supplements. In Australia, dietary supplement use during preconception is relatively high. However, supplementation of recommended nutrients, including folic acid and iodine, could be improved.

    This study describes the cross sectional and longitudinal data of endodontic and periapical status of new patients presenting to a major dental hospital, and assesses the relationships between tooth-related variables with apical periodontitis. The records of 695 patients were randomly selected and the orthopantomograms of these patients up to 31 October 2014 were reviewed by two endodontists. The periapical status of teeth was recorded using the periapical index. The presence and quality of root fillings and coronal restorations were recorded. Statistical analysis included Fleiss' kappa, Cohen's kappa and logistic regression set at P < 0.05. Of 695 patient records and 16 936 teeth examined, 138 (19.9%) patients or 284 (1.7%) teeth had root fillings and 179 (25.8%) patients or 325 (1.9%) teeth had apical periodontitis. Root fillings and coronal restorations were adequate in 34.6% and 69.4% teeth, respectively. A large proportion (47%) of teeth with apical periodontitis remained unchanged in subsequent orthopantomograms. There was lower prevalence of root filled teeth or apical periodontitis in the present study compared with international studies. The frequency of adequate root fillings must be considered unacceptably low. Teeth with apical periodontitis may remain quiescent in the absence of caries or restorative breakdown. © 2017 Australian Dental Association.

    Many students have poor mental health literacy when they finish Bachelor of Nursing courses. This paper presents the findings of a longitudinal study of Australian Bachelor of Nursing students' mental health literacy about the effectiveness of interventions for people with schizophrenia. The 'Attitudes and Beliefs about Mental Health Problems: Professional and Public Views' questionnaire was used with a non-probability sample of nursing students. A time series approach to data collection was used, with data collected on three occasions between 2005 and 2007. Ethics approval was obtained from a university ethics committee. Data were analysed using SPSS Version 15.0. The students' views about the helpfulness of interventions showed a significant and positive improvement as they progressed through the course. There were significant differences over time in their views about the helpfulness of professional and lay interventions, their opinions about the helpfulness of mental health and other medications, and the usefulness of activity and non-pharmacological interventions. Because nursing students need to be mental health literate when they complete their course, mental health nursing content should be incorporated earlier in comprehensive undergraduate curricula and incrementally increased in each year of study.

    The Western Australian Data Linkage System is one of a few comprehensive, population-based data linkage systems worldwide, creating links between information from different sources relating to the same individual, family, place or event, while maintaining privacy. The Raine Study is an established cohort study with more than 2000 currently active participants. Individual consent was obtained from participants for information in publicly held databases to be linked to their study data. A waiver of consent was granted where it was impracticable to obtain consent. Approvals to link the datasets were obtained from relevant ethics committees and data custodians. The Raine Study dataset was subsequently linked to academic testing data collected by the Western Australian Department of Education. Examination of diet and academic performance showed that children who were predominantly breastfed for at least 6 months scored higher academically at age 10 than children who were breastfed for less than 6 months. A further study found that better diet quality at ages 1, 2 and 3 years was associated with higher academic scores at ages 10 and 12 years. Examination of nutritional intake at 14 years of age found that a better dietary pattern was associated with higher academic performance. The detailed longitudinal data collected in the Raine Study allowed for adjustment for multiple covariates and confounders. Data linkage reduces the burden on cohort participants by providing additional information without the need to contact participants. It can give information on participants who have been lost to follow-up; provide or complement missing data; give the opportunity for validation studies comparing recall of participants with administrative records; increase the population sample of studies by adding control participants from the general population; and allow for the adjustment of multiple covariates and confounders. The Raine Study dataset is extensive and detailed, and can be

    Longitudinal data from a nationally representative sample of Australians were used to evaluate mean-level differences and rank-order stability in personality traits assessed twice over a 4-year time span (n = 13,134). Extraversion, Neuroticism, and Openness declined over the life span, whereas Agreeableness increased among young cohorts, was stable among middle-aged cohorts, and declined among the oldest old. Cross-sectional analyses suggested an increase in Conscientiousness throughout the life span, though longitudinal analyses suggested a slight decline in late life. There was an inverted U-shaped pattern for rank-order stability, with peak stability occurring in middle age. For three of the Big Five domains (Extraversion, Agreeableness, and Conscientiousness), age-related differences appeared to be somewhat more pronounced before age 30 than after age 30. 2013 APA, all rights reserved

Methods. Gender-stratified multilevel linear regressions were used to examine associations between green space and objective measures of weight status in the Longitudinal Study of Australian Children, a nationally representative source of data on 4,423 children aged 6 y to 13 y. WC and WtHR were measured objectively. Percentage green space within the local area of residence was calculated. Effect modification by age was explored, adjusting for socioeconomic confounding.

    We examined the relationships among experiences of interpersonal violence, mental health, and sexual identity in a national sample of young adult women in Australia. We used existing data from the third (2003) wave of young adult women (aged 25-30) in the Australian Longitudinal Study on Women's Health (ALSWH). We conducted bivariate analyses and fit multiple and logistic regression models to test experiences of six types of interpersonal violence (physical abuse, severe physical abuse, emotional abuse, sexual abuse, harassment, and being in a violent relationship), and the number of types of violence experienced, as predictors of mental health. We compared types and number of types of violence across sexual identity subgroups. Experiences of interpersonal violence varied significantly by sexual identity. Controlling for demographic characteristics, compared to exclusively heterosexual women, mainly heterosexual and bisexual women were significantly more likely to report physical, sexual, and emotional abuse. Mainly heterosexual and lesbian women were more likely to report severe physical abuse. Mainly heterosexual women were more than three times as likely to have been in a violent relationship in the past three years, and all three sexual minority subgroups were two to three times as likely to have experienced harassment. Bisexual women reported significantly higher levels of depression than any of the other sexual identity groups and scored lower on mental health than did exclusively heterosexual women. In linear regression models, interpersonal violence strongly predicted poorer mental health for lesbian and bisexual women. Notably, mental health indicators were similar for exclusively heterosexual and sexual minority women who did not report interpersonal violence. Experiencing multiple types of interpersonal violence was the strongest predictor of stress, anxiety and depression. Interpersonal violence is a key contributor to mental health disparities

    To examine barriers to childhood immunisation experienced by parents in Australia. Cross-sectional analysis of secondary data. Nationally representative Longitudinal Study of Australian Children (LSAC). Five thousand one hundred seven infants aged 3-19 months in 2004. Maternal report of immunisation status: incompletely or fully immunised. Overall, 9.3% (473) of infants were incompletely immunised; of these just 16% had mothers who disagreed with immunisation. Remaining analyses focussed on infants whose mother did not disagree with immunisation (N=4994) (of whom 8% [398] were incompletely immunised). Fifteen variables representing potential immunisation barriers and facilitators were available in LSAC; these were entered into a latent class model to identify distinct clusters (or 'classes') of barriers experienced by families. Five classes were identified: (1) 'minimal barriers', (2) 'lone parent, mobile families with good support', (3) 'low social contact and service information; psychological distress', (4) 'larger families, not using formal childcare', (5) 'child health issues/concerns'. Compared to infants from families experiencing minimal barriers, all other barrier classes had a higher risk of incomplete immunisation. For example, the adjusted risk ratio (RR) for incomplete immunisation was 1.51 (95% confidence interval: 1.08-2.10) among those characterised by 'low social contact and service information; psychological distress', and 2.47 (1.87-3.25) among 'larger families, not using formal childcare'. Using the most recent data available for examining these issues in Australia, we found that the majority of incompletely immunised infants (in 2004) did not have a mother who disagreed with immunisation. Barriers to immunisation are heterogeneous, suggesting a need for tailored interventions. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

    We wished to clarify the link between bilingualism and cognitive decline, and examine whether improved executive function due to bilingualism may be a factor in preventing cognitive decline. We used the Australian Longitudinal Study of Ageing which collected data on 2087 participants aged over 65 over 20 years. We compared baseline demographics, health, and social characteristics between bilingual and non-bilingual participants. We used linear mixed models analysis to explore the effect of bilingualism on MMSE score over time and linear regression to explore the effect of bilingualism on baseline MMSE scores, controlling for pre-specified potential confounders. Bilingual participants had lower baseline MMSE scores than the non-bilingual population (mean difference = -2.3 points; 95% confidence intervals = 1.56-2.90). This was fully explained by education and National Adult Reading Test scores (17.4; standard deviation [SD] =7.7 versus 28.1; SD = 8.2) which also partly explained baseline executive function test scores differences. Bilingual and non-bilingual participants did not differ in MMSE decline over time (-0.33 points, P = 0.31) nor on baseline tests of executive function (-0.26, P = 0.051). In this cohort, education rather than bilingualism was a predictor of MMSE score, and being bilingual did not protect from cognitive decline. We conclude that bilingualism is complex, and when it is not the result of greater educational attainment, it does not always protect from cognitive decline. Neuroprotective effects of bilingualism over time may be attributable to the precise patterns of language use but not to bilingualism per se. Copyright © 2017 John Wiley & Sons, Ltd.

    Full Text Available Abstract Background Isolation, long work days, climate change and globalization are just some of the many pressures that make farming a vulnerable occupation for incurring mental health issues. The objective of this study was to determine whether farming in Australia is associated with poorer wellbeing, physical and mental health, and less health service use. Methods The Australian Rural Mental Health Study, a longitudinal cohort study was analysed over four time points comparing farmers with non-farming workers (n = 1184 at baseline. Participants were recruited from rural NSW, Australia. A number of physical, mental health, wellbeing, service use outcomes were assessed using generalised estimating equations including all waves in each model. Barriers to seeking help were also assessed. Results Farmers who lived remotely reported worse mental health (β −0.33, 95 % CI −0.53, −0.13 and wellbeing (β −0.21(95 % CI −0.35, −0.06 than remote non-farm workers regardless of financial hardship, rural specific factors eg drought worry, or recent adverse events. All farmers were no different to non-farming workers on physical health aspects except for chronic illnesses, where they reported fewer illnesses (OR 0.66, 95 % CI 0.44, 0.98. All farmers were half as likely to visit a general practitioner (GP or a mental health professional in the last 12 months as compared to non-farm workers regardless of location (OR 0.59, 95 % CI 0.35, 0.97. Rural workers felt that they preferred to manage themselves rather than access help for physical health needs (50 % or mental health needs (75 % and there was little difference between farmers and non-farm workers in reasons for not seeking help. Conclusions Remoteness is a significant factor in the mental health and wellbeing of farmers, more so than financial stress, rural factors and recent adverse events. Creative programs and policies that improve access for farmers to GPs and mental health

    2015-01-01

    Objective We analyzed whether further education in young adult and mid-life [adult educational mobility] influences physical functioning and depressive symptoms in women. Methods 14247 women born 1973–78 (younger cohort) and 13715 women born 1946–51 (mid-aged cohort) from the Australian Longitudinal Study on Women’s Health were followed for 14–16 years. Measures were the Short-Form 36 Health Survey physical functioning subscale (SF-36 PF) and Centre for Epidemiologic Studies 10-item Depression Scale (CESD-10). Linear mixed modelling, accounting for time varying covariates, assessed the influence of further education on physical functioning and depressive symptoms over time. Sensitivity analysis to assess the impact of missing data was conducted using multiple imputation. Results Compared to younger women with a pre-existing high level of education, women gaining further education (up to age 39 years) from low levels had lower SF-36 PF scores (poorer physical functioning) (fully adjusted beta estimates (95%CIs) -1.52 (-2.59, -0.44)) while those gaining further education from middle to high levels showed equivalent SF-36 PF scores (-0.08 (-0.61, 0.44)). A similar pattern was shown for CESD-10 scores (0.78 (0.29, 1.25); -0.02 (-0.26, 0.21), respectively) where higher scores represented more depressive symptoms. For mid-age women, further education from a middle to high level resulted in equivalent SF-36 PF scores (-0.61 (-1.93,0.71)) but higher CESD-10 scores (0.49 (0.11, 0.86)), compared to highly educated women. Conclusion Women who delay further education until they are aged between their 40s and 60s can improve or maintain their physical functioning but may have missed the critical time to minimise depressive symptomatology. Public health policy should focus on encouraging women to upgrade their educational qualifications earlier in life in order to potentially offset the negative associations between their initial lower socio-economic position class of

    To identify whether psychological distress is associated with an increased risk of falling into poverty, giving a more complete picture of how psychological distress affects living standards. Longitudinal analysis of the nationally representative Household Income and Labour Dynamics in Australian (HILDA) survey using Poisson regression models to estimate relative risk of falling into income poverty and multidimensional poverty between 2007 and 2012. The sample was limited to those who were not already in income poverty in 2007. Psychological distress was identified using the Kessler-10 (K10) scale. After adjusting for confounding factors, having moderate psychological distress increased the risk of falling into income poverty by 1.62 (95% CI 1.31-2.01, p poverty by 1.85 (95% CI 1.37-2.48, p poverty by 2.40 (95% CI 1.80-3.20, p poverty by 3.68 (95% CI 2.63-5.15, p poverty (RR: 1.29, 95% CI 1.04-1.61, p = 0.0210) and those who experienced multidimensional poverty (RR: 1.69, 95% CI 1.32-2.17, p poverty. To date, the increased risk of falling into poverty that is associated with elevated levels of psychological distress has been an overlooked burden of the condition.

    To identify barriers to fruit and vegetable intake for Indigenous Australian children and quantify factors related to these barriers, to help understand why children do not meet recommendations for fruit and vegetable intake. We examined factors related to carer-reported barriers using multilevel Poisson models (robust variance); a key informant focus group guided our interpretation of findings. Eleven diverse sites across Australia. Australian Indigenous children and their carers (N 1230) participating in the Longitudinal Study of Indigenous Children. Almost half (45 %; n 555/1230) of carers reported barriers to their children's fruit and vegetable intake. Dislike of fruit and vegetables was the most common barrier, reported by 32·9 % of carers; however, we identified few factors associated with dislike. Carers were more than ten times less likely to report barriers to accessing fruit and vegetables if they lived large cities v. very remote areas. Within urban and inner regional areas, child and carer well-being, financial security, suitable housing and community cohesion promoted access to fruit and vegetables. In this national Indigenous Australian sample, almost half of carers faced barriers to providing their children with a healthy diet. Both remote/outer regional carers and disadvantaged urban/inner regional carers faced problems accessing fruit and vegetables for their children. Where vegetables were accessible, children's dislike was a substantial barrier. Nutrition promotion must address the broader family, community, environmental and cultural contexts that impact nutrition, and should draw on the strengths of Indigenous families and communities.

    The purpose was to examine the relationship between different types of social networks and memory over 15 years of followup in a large cohort of older Australians who were cognitively intact at study baseline. Our specific aims were to investigate whether social networks were associated with memory, determine if different types of social networks had different relationships with memory, and examine if changes in memory over time differed according to types of social networks. We used five waves of data from the Australian Longitudinal Study of Ageing, and followed 706 participants with an average age of 78.6 years (SD 5.7) at baseline. The relationships between five types of social networks and changes in memory were assessed. The results suggested a gradient of effect; participants in the upper tertile of friends or overall social networks had better memory scores than those in the mid tertile, who in turn had better memory scores than participants in the lower tertile. There was evidence of a linear, but not quadratic, effect of time on memory, and an interaction between friends' social networks and time was apparent. Findings are discussed with respect to mechanisms that might explain the observed relationships between social networks and memory.

    Full Text Available Abstract Background Obstructive sleep apnoea is a common disorder with under-rated clinical impact, which is increasingly being recognised as having a major bearing on global disease burden. Men are especially vulnerable and become a priority group for preventative interventions. However, there is limited information on prevalence of the condition in Australia, its co-morbidities, and potential risk factors. Methods We used data from 13,423 adult men included in the baseline wave of Ten to Men, an Australian national study of the health of males, assembled using stratified cluster sampling with oversampling from rural and regional areas. Those aged 18–55 years self-completed a paper-based questionnaire that included a question regarding health professional-diagnosed sleep apnoea, physical and mental health status, and health-related behaviours. Sampling weights were used to account for the sampling design when reporting the prevalence estimates. Odds ratios were used to describe the association between health professional-diagnosed sleep apnoea and potential correlates while adjusting for age, country of birth, and body-mass index (BMI.

    Statin therapy may cause myopathy, but long-term effects on physical function are unclear. We investigated whether statin use is associated with poorer physical function in two population-based cohorts of older adults. Data were from 691 men and women (aged 69-102 years in 2005/2006) in the LASA (Longitudinal Aging Study Amsterdam) and 5912 women (aged 79-84 years in 2005) in the ALSWH (Australian Longitudinal Study on Women's Health). Statin use and dose were sourced from containers (LASA) and administrative databases (ALSWH). Physical function was assessed using performance tests, questionnaires on functional limitations and the SF-12 (LASA) and SF-36 (ALSWH) questionnaires. Cross-sectional (both studies) and 3-year prospective associations (ALSWH) were analysed for different statin dosage using linear and logistic regression. In total, 25 % of participants in LASA and 61 % in ALSWH used statins. In the cross-sectional models in LASA, statin users were less likely to have functional limitations (percentage of subjects with at least 1 limitation 63.9 vs. 64.2; odds ratio [OR] 0.6; 95 % confidence interval [CI] 0.3-0.9) and had better SF-12 physical component scores (mean [adjusted] 47.3 vs. 44.5; beta [B] = 2.8; 95 % CI 1.1-4.5); in ALSWH, statin users had better SF-36 physical component scores (mean [adjusted] 37.4 vs. 36.5; B = 0.9; 95 % CI 0.3-1.5) and physical functioning subscale scores (mean [adjusted] 55.1 vs. 52.6; B = 2.4; 95 % CI 1.1-3.8) than non-users. Similar associations were found for low- and high-dose users and in the prospective models. In contrast, no significant associations were found with performance tests. Two databases from longitudinal population studies in older adults gave comparable results, even though different outcome measures were used. In these two large cohorts, statin use was associated with better self-perceived physical function.

    Full Text Available Abstract Background Suicide is a leading cause of death in Australian males aged 18 to 55. Non-fatal suicidal behaviours and thoughts are indicators of increased risk for future suicide. Suicidal behaviour is complex and multi-determined. Research supports the involvement of stressful life events in suicide and suicidal behaviour, however the evidence regarding suicidal thoughts is less developed. This study investigates stressful life events in relation to suicidal ideation in a large cohort of adult males recruited into Ten to Men, the Australian Longitudinal Study on Male Health. Methods Baseline data from a national cohort of 13, 884 males aged 18–55 years on suicidal behaviour, psychiatric disorder and life events was used. Multivariable logistic regressions were conducted with current suicidal ideation as the outcome and 12 month life events, 12 month depression, anxiety and harmful/hazardous alcohol use, and socio-demographics as covariates. Further logistic regression models investigated the relative risk of life stress alone, depression/alcohol/anxiety alone and co-occurring life stress and depression/alcohol/anxiety. Results In multivariable models there was an independent contribution to suicidal ideation for six of 24 life events (ORs 1.27–1.95, 12 month depression (OR 4.49 harmful alcohol use (OR 1.38 and anxiety disorders (OR 1.27. Life events co-occurring with depression (OR 10.3 was higher risk than either alone (depression OR 6.6; life stress OR 2.6. There was a lesser effect for co-occurrence in the anxiety and harmful alcohol use models. Conclusion Life events appear to be related to suicidal ideation independent of depression, anxiety and harmful alcohol use in adult males, however if life events occur in the context of depression that risk is substantially increased.

    The impact of alcohol-related violence on individuals and society continues to receive attention from both media and policy makers. However, the longitudinal relationship between alcohol consumption and violence is unclear, with findings from prospective studies producing mixed results. The current study utilized Australian data from the International Youth Development Study to examine longitudinal relationships between alcohol consumption and severe interpersonal violence across the developmental periods of early adolescence to late adolescence/emerging adulthood. The full sample comprised 849 adolescents (53.8 % female) who had been followed up over a 5 year period, from Grade 7 secondary school (age 13) until Grade 11 secondary school (age 17). Cross-lagged path analysis was used to examine reciprocal relationships between alcohol consumption and interpersonal violence; analyses controlled for a range of covariates considered to be common risk factors for both behaviors. Alcohol use during early and mid adolescence was found to predict violence 2 years later, whereas a bi-directional relationship between adolescent heavy episodic drinking and violence was observed. Some of these relationships were not significant when covariates such as family conflict and affiliation with antisocial and drug using friends were included in the models. These findings suggest that risk processes begin in late childhood or very early adolescence; efforts to reduce one problem behavior are likely to reduce the other. Further, the role that social and family contexts have in influencing the relationships between alcohol use and interpersonal violence should be considered in future research to better inform preventive efforts.

    Despite growing interest and concern about men's mental health during the perinatal period, we still do not know whether men are more vulnerable to mental health problems during this time. The current study is one of the first to use longitudinal, population-based data to investigate whether becoming an expectant and/or new father is associated with increases in psychological distress. We analyzed 10 waves of data collected annually (from 2001 to 2010) from the nationally representative Household, Income, and Labour Dynamics in Australia (HILDA) Survey. Over this time, 349 men were identified as new fathers (first child aged fatherhood. Longitudinal mixed models showed no significant increase in psychological distress as a function of expectant or new fatherhood; instead, some improvement in mental health was observed. The finding suggests that expectant and new fathers are not at greater risk of poor mental health. Future epidemiologic research should continue to identify those men who are most (and least) at risk during the perinatal period in order to target resources and assistance most effectively. © The Author 2014.

    Social patterning of dietary-related diseases may partly be explained by population disparities in children's diets. This study aimed to determine which early life socioeconomic factors best predict dietary trajectories across childhood. For waves 2-6 of the Baby (B) Cohort (ages 2-3 to 10-11 years) and waves 1-6 of the Kindergarten (K) Cohort (ages 4-5 to 14-15 years) of the Longitudinal Study of Australian Children, we constructed trajectories of dietary scores and of empirically derived dietary patterns. Dietary scores, based on the Australian Dietary Guidelines, summed children's consumption frequencies of seven groups of foods or drinks over the last 24 hours. Dietary patterns at each wave were derived using factor analyses of 12-16 food or drink items. Using multinomial logistic regression analyses, we examined associations of baseline single (parental education, remoteness area, parental employment, income, food security and home ownership) and composite (socioeconomic position and neighbourhood disadvantage) factors with adherence to dietary trajectories. All dietary trajectory outcomes across both cohorts showed profound gradients by composite socioeconomic position but not by neighbourhood disadvantage. For example, odds for children in the lowest relative to highest socioeconomic position quintile being in the 'never healthy' relative to the 'always healthy' score trajectory were OR=16.40, 95% CI 9.40 to 28.61 (B Cohort). Among the single variables, only parental education consistently predicted dietary trajectories. Child dietary trajectories vary profoundly by family socioeconomic position. If causal, reducing dietary inequities may require researching underlying pathways, tackling socioeconomic inequities and targeting health promoting interventions to less educated families. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Internationally there has been a growth in the use of publicly funded service markets as a mechanism to deliver health and social services. This has accompanied the emergence of 'self-directed care' in a number of different policy areas including disability and aged care - often referred to as 'personalisation' (Giaimo and Manow, Comp. Pol Stud 32:967-1000, 1999; Needham, Public Money Manage 30:136-8, 2010; [Hood], [The Idea of Joined-up Government: A Historical Perspective], [2005]; Klijn and Koppenjan, Public Manage 2:437-54, 2000, Greener, Policy Polit 36:93-108, 2008). These reforms are underpinned by an idea that individuals should be placed in control of their own service needs, given funding directly by government and encouraged to exercise choice and control through purchasing their own services. A major challenge for governments in charge of these reforms is determining the best way to structure and govern emerging service markets markets. Given the growing international embrace of market-based reform mechanisms to provide essential services to citizens, finding ways to ensure they promote, and not diminish, people's health and wellbeing is vital. The Australian National Disability Insurance Scheme (NDIS) is Australia's first national approach to the use of personalised budgets. The program of research outlined in this paper brings together streams from a range of different studies in order to investigate the implementation of the NDIS longitudinally across different administrative levels of government, service providers and scheme participants. This programme of research will make a contribution to our understanding of the Australian scheme and how individualised funding operates within this context, but will also generate much needed evidence that will have relevance to other jurisdictions and help fill a gap in the evidence base.

    Emotional intelligence (EI) has been associated with positive outcomes for nursing students. Higher EI is associated with personal wellbeing and stress management, higher academic performance, stronger nursing leadership and practice performance, and greater patient safety. While there is an increasing body of evidence on nursing students' EI, there is minimal evidence on EI over time during pre-registration programs. To measure EI in pre-registration nursing students from program commencement to conclusion to ascertain EI over time and examine the relationship between EI and academic performance. Longitudinal repeated measures study between March 2010-February 2013 at a metropolitan university in Australia. 111 nursing students (74.8% female) contributed data on at least two occasions. Participants were enrolled in a pre-registration Master of Nursing degree. Half the cohort (55.0%) comprised Graduate Entry students who completed the course in two years full time. The other 45% were enrolled in an undergraduate degree in arts, science or health science, combined with the same pre-registration Master of Nursing Degree. These students completed their Combined Degree program in four years full time. Participants had a mean age of 24.7years (SD=7.36). EI was measured for commencing students (T1) using the Assessing Emotions Scale (AES), then a further three times: end of first year (T2; 9 months follow up); beginning of second year (12 months follow up; T3) and end of the program (T4; 24/36 months follow up). Students' EI was found to increase across the program; one subscale of EI (managing others' emotions) was related to higher academic performance; and there was a significant increase in the Utilising Emotions subscale scores over time. Pre-registration nurse education contributes to strengthening students' EI over time. Specific EI education scaffolded throughout programs is recommended in pre-registration curricula.

  12. Higher maternal protectiveness is associated with higher odds of child overweight and obesity: a longitudinal Australian study.

    Directory of Open Access Journals (Sweden)

    Kirsten J Hancock

    Full Text Available In recent years there has been an increasing interest in overprotective parenting and the potential role it plays in child development. While some have argued that a trend towards increased parental fear and reduced opportunity for independent mobility may be linked to increasing rates of child overweight and obesity, there is limited empirical information available to support this claim. Using data from the Longitudinal Study of Australian Children, this study aimed to examine the longitudinal relationships between maternal protectiveness and child overweight and obesity. A cohort of 4-5 year old children was followed up at 6-7, 8-9 and 10-11 years of age (n  =  2596. Measures included a protective parenting scale administered when children were 6-7 and 8-9 years of age, child body mass index (BMI, family characteristics including household income, neighbourhood disadvantage, child's position amongst siblings, and maternal BMI, education, employment, mental health and age at first birth. International Obesity Taskforce age- and sex-specific BMI cut points were used to determine if children were in the normal, overweight or obese BMI range. There was no association between maternal protectiveness and the odds of children being overweight or obese at age 4-5, 6-7 or 8-9 years. However at age 10-11 years, a 1 standard deviation increase in maternal protectiveness was associated with a 13% increase in the odds of children being overweight or obese. The results provide evidence of a relationship between maternal protectiveness and child overweight and obesity, however further research is required to understand the mechanism(s that links the two concepts.

  13. Family and neighbourhood socioeconomic inequalities in childhood trajectories of BMI and overweight: longitudinal study of Australian children.

    Pauline W Jansen

    Full Text Available BACKGROUND: Socioeconomic inequalities in longitudinal patterning of childhood overweight could cause marked differentials in total burden by adulthood. This study aims to determine timing and strength of the association between socioeconomic status (SES and children's body mass index (BMI in the pre- and primary school years, and to examine socioeconomic differences in overweight trajectories across childhood. METHODS: Participants were 4949 children from the Longitudinal Study of Australian Children. BMI was measured at four biennial waves starting at age 4-5 years in 2004. Developmental trajectories of childhood overweight were identified with latent class analyses. Composite variables of family and neighbourhood SES were used. RESULTS: Socioeconomic differences in mean BMI z-scores already present at age 4-5 more than doubled by age 10-11 years, reflecting decreasing mean BMI among advantaged rather than increasing means among disadvantaged children. Latent class analysis identified children with 'stable normal weight' (68%, and with 'persistent' (15%, 'late-onset' (14%, and 'resolving' overweight (3%. Risks of persistent and late-onset childhood overweight were highest among low SES families (e.g. most disadvantaged quintile: OR(persistent = 2.51, 95%CI: 1.83-3.43, and only partly explained by birth weight and parental overweight. Relationships with neighbourhood SES were weaker and attenuated fully on adjustment for family SES. No socioeconomic gradient was observed for resolving overweight. CONCLUSIONS: Childhood has become the critical period when socioeconomic inequalities in overweight emerge and strengthen. Although targeting disadvantaged children with early overweight must be a top priority, the presence of childhood overweight even among less-disadvantaged families suggests only whole-society approaches will eliminate overweight-associated morbidity.

    This study examined the factors that predict employees' perceptions of procedural justice in university settings. The paper also reviews the ethical aspects of justice and psychological contracts within employment relationships. The study examined the predictors of perceived procedural justice in a two-wave longitudinal sample of 945 employees from 13 universities by applying the Job Demands-Resources theoretical model of stress. The proposed predictors were classified into two categories: Job demands of work pressure and work-home conflict; and job resources of job security, autonomy, trust in senior management, and trust in supervisor. The predictor model also examined job satisfaction and affective organizational commitment, demographic (age, gender, tenure, role) and individual characteristics (negative affectivity, job involvement) as well as Time 1 (T1) perceptions of procedural justice to ensure that tests were rigorous. A series of hierarchical multiple regression analyses found that job satisfaction at T1 was the strongest predictor of perceived procedural justice at Time 2. Employees' trust in senior management, and their length of tenure also positively predicted justice perceptions. There were also differences between academic and non-academic staff groups, as non-academic employees' level of job satisfaction, trust in senior management, and their length of organizational tenure predicted procedural justice perceptions, whereas for academics, only job satisfaction predicted perceived justice. For the "all staff" category, job satisfaction was a dominant and enduring predictor of justice, and employees' trust in senior management also predicted justice. Results highlight the importance of workplace factors in enhancing fair procedures to encourage reciprocity from employees. As perceived procedural justice is also conceptually linked to the psychological contract between employees-employers, it is possible that employees' levels of job satisfaction and

    Data from the Australian Longitudinal Study on Women's Health were used to examine how work was associated with time spent sleeping, sitting and in physical activity (PA), in working women. Young (31-36 years; 2009) and mid-aged (59-64 years; 2010) women reported sleep (categorised as shorter ≤6 h/day and longer ≥8 h/day) and sitting time (work, transport, television, non-work computer, and other; summed for total sitting time) on the most recent work and non-work day; and moderate and vigorous PA (categorised as meeting/not meeting guidelines) in the previous week. Participants reported occupation (manager/professional; clerical/sales; trades/transport/labourer), work hours (part-time; full-time) and work pattern (shift/night; not shift/night). The odds of shorter sleep on work days was higher in both cohorts for women who worked shift or night hours. Longer sitting time on work days, made up primarily of sitting for work, was found for managers/professionals, clerical/sales and full-time workers. In the young cohort, clerical/sales workers and in the mid-aged cohort, full-time workers were less likely to meet PA guidelines. These results suggest multiple behaviour interventions tailored to work patterns and occupational category may be useful to improve the sleep, sitting and activity of working women.

    Self-efficacy has numerous benefits for active and healthy aging, including giving the people the ability to make positive changes to their living standards and lifestyles. The present study aims to determine whether falling into multidimensional poverty lowers self-efficacy. Longitudinal analysis of waves 7-11 (2007-2011) of the nationally representative Household, Income and Labor Dynamics in Australia survey using linear regression models. The analysis focused on the Australian population aged 65 years and older. The Freedom Poverty Measure was used to identify those in multidimensional poverty. Those who fell into multidimensional poverty for 3 or 4 years between 2007 and 2011 had their self-efficacy scores decline by an average of 27 points (SD 21.2). Those who fell into poverty had significantly lower self-efficacy scores in 2011 - up to 57% lower (-66.6%, -45.7% P poverty for 3 or 4 years between 2007 and 2011 than those who were never in poverty. Falling into multidimensional poverty lowers the self-efficacy scores of older people. In order to improve the chances of older people making long-term changes to improve their living standards, feelings of self-efficacy should first be assessed and improved.

    To investigate the combined effect of education and reproductive history on weight trajectory. The association of education with weight trajectory (1996-2012) in relation to reproductive history was analyzed among 9,336 women (born 1973-1978) from the Australian Longitudinal Study on Women's Health using random effects models. Compared with women with a university degree/higher, lower-educated women were 2 kg heavier at baseline and gained an additional 0.24 kg/year. Giving birth was associated with an increase in weight which was more pronounced among women having their first birth 32 years. While younger first-time mothers had a steeper weight trajectory (∼+0.16 kg/year, 95% CI: 0.1-0.3), this was less steep among lower-educated women. High-educated women with a second birth between 26 and 32 years had 0.9 kg decreased weight after this birth, while low-educated women gained 0.9 kg. While the effect of having children on weight in young adulthood was minimal, women having their first birth Educational differences in weight persisted after accounting for reproductive history, suggesting a need to explore alternative mechanisms through which social differences in weight are generated. © 2016 The Obesity Society.

    This paper explores women's experiences of drought in Australia. Despite the significance of drought for rural life in Australia, there is little research seeking to understand its psychological consequences. There is also a need to recognise gendered experiences of drought and for research that addresses its long-term effects as people age in prolonged drought-affected areas. The study explores longitudinal qualitative data collected by the Australian Longitudinal Study on Women's Health. Free-text comments (n = 217), collected via mailed survey at five time points (1996, 1998, 2001, 2004, 2007) from the same 77 women, were subjected to a narrative analysis. Participants from the Australian Longitudinal Study on Women's Health who were aged 45-50 when the study began in 1996. Findings indicate that drought has an impact on women as they age, particularly in reference to menopause, access to support systems and retirement. This study concludes that the experience of drought cannot be disentangled from the realities of gender and ageing. © 2012 The Authors.

    Autism is associated with high cost to individuals, families, communities and government. Understanding educational and participation trajectories during the school years, and factors influencing these, is fundamental to reducing financial and personal costs. The primary aim of this study is to document the trajectories of Australian students with autism during their education. The secondary aim is to examine personal (eg, student skills) and environmental (eg, school setting) factors associated with differing trajectories and outcomes. The cross-sequential longitudinal study will recruit two cohorts of 120 parents/caregivers of children with autism. Cohort 1 aged between 4 and 5 years and cohort 2 between 9 and 10 years to start the study. Information will be gathered from parents, teachers and school principals at six annual time points (T1 to T6). Parents will be emailed a link to an online initial questionnaire (T1) and then contacted annually and asked to complete either an extended questionnaire (T3, T5 and T6) or an abbreviated questionnaire (T2, T4). Where consent is given, the child's current school will be contacted annually (T1 to T6) and teacher and school principal asked to complete questionnaires about the child and school. Parent and school questionnaires are comprised of questions about demographic and school factors that could influence trajectories and a battery of developmental and behavioural assessment tools designed to assess educational and participation trajectories and outcomes. Surveys will provide longitudinal data on educational and participation trajectories for children and adolescents with autism. In addition cross-sectional comparisons (within or between age groups) at each time point and cohort effects will be explored. Ethics approvals have been granted for this study by all recruiting sites and universities in the project. Study findings will inform policy and practice to promote successful inclusion and participation of children

    Receptive vocabulary develops rapidly in early childhood and builds the foundation for language acquisition and literacy. Variation in receptive vocabulary ability is associated with variation in children's school achievement, and low receptive vocabulary ability is a risk factor for under-achievement at school. In this study, bivariate and multivariate growth curve modelling was used to estimate trajectories of receptive vocabulary development in relation to a wide range of candidate child, maternal and family level influences on receptive vocabulary development from 4-8 years. The study sample comprised 4332 children from the first nationally representative Longitudinal Study of Australian Children (LSAC). Predictors were modeled as risk variables with the lowest level of risk as the reference category. In the multivariate model, risks for receptive vocabulary delay at 4 years, in order of magnitude, were: Maternal Non- English Speaking Background (NESB), low school readiness, child not read to at home, four or more siblings, low family income, low birthweight, low maternal education, maternal mental health distress, low maternal parenting consistency, and high child temperament reactivity. None of these risks were associated with a lower rate of growth from 4-8 years. Instead, maternal NESB, low school readiness and maternal mental health distress were associated with a higher rate of growth, although not sufficient to close the receptive vocabulary gap for children with and without these risks at 8 years. Socio-economic area disadvantage, was not a risk for low receptive vocabulary ability at 4 years but was the only risk associated with a lower rate of growth in receptive vocabulary ability. At 8 years, the gap between children with and without socio-economic area disadvantage was equivalent to eight months of receptive vocabulary growth. These results are consistent with other studies that have shown that social gradients in children's developmental outcomes

    People with strong feelings of 'self-efficacy', i.e. how much a person feels they have control over their life, perform better in the workplace. However, little is known about negative influences on feelings of self-efficacy. In view of the increasing number of people whose income places them below the poverty line despite being in employment, poverty may negatively influence feelings of self-efficacy and hence workplace productivity. To assess whether falling into poverty lowers self-efficacy. Longitudinal analysis of waves 7 to 11 of the nationally representative Household, Income and Labour Dynamics in Australia (HILDA) survey, using linear regression models. Those who fell into multidimensional poverty (income poverty plus poor health or insufficient level of education attainment) had significantly lower self-efficacy scores (up to 18% lower (95% CI -31% to -1%, P accounting for initial self-efficacy score and other confounding factors. Income uniquely accounted for 3% of the variance in self-efficacy scores, physical health for 10%, mental health for 78% and education for 1%. Given the known links between self-efficacy and workplace productivity, workers who are below the poverty line may be at risk of poor productivity due to the experience of poverty. In addition to the poor outcomes from the employer's perceptive, this may also lead to a negative spiral for the employee. © The Author 2016.

    To determine the accuracy of the caries risk assessment system and performance of clinicians in their attempts to predict caries for children during routine practice. Longitudinal study. Data on caries risk assessment conducted by clinicians during routine practice while providing care for children in the South Australian School Dental Service (SA SDS) were collected from electronic patient records. Baseline data on caries experience, clinicians' ratings of caries risk status and child demographics were obtained for all SA SDS patients aged 5-15 years examined during 2002-2005. Children's caries incidence rate, calculated using examination data after a follow-up period of 6-48 months from baseline, was used as the gold standard to compute the sensitivity (Se) and specificity (Sp) of clinicians' baseline ratings of caries risk. Multivariate binomial regression models were used to evaluate effects of children's baseline characteristics on Se and Sp. A total of 133 clinicians rated caries risk status of 71 430 children during 2002-2005. The observed Se and Sp were 0.48 and 0.86, respectively (Se+Sp=1.34). Caries experience at baseline was the strongest factor influencing accuracy in multivariable regression model. Among children with no caries experience at baseline, overall accuracy (Se+Sp) was only 1.05, whereas it was 1.28 among children with at least one tooth surfaces with caries experience at baseline. Clinicians' accuracy in predicting caries risk during routine practice was similar to levels reported in research settings that simulated patient care. Accuracy was acceptable in children who had prior caries experience at the baseline examination, while it was poor among children with no caries experience.

    To study social patterning of overeating and symptoms of disordered eating in a general population. A representative, population-based cohort study. The Australian Longitudinal Study on Women's Health (ALSWH), Survey 1 in 1996 and Survey 2 in 2000. Women (n 12 599) aged 18-23 years completed a questionnaire survey at baseline, of whom 6866 could be studied prospectively. Seventeen per cent of women reported episodes of overeating, 16 % reported binge eating and 10 % reported compensatory behaviours. Almost 4 % of women reported symptoms consistent with bulimia nervosa. Low education, not living with family, perceived financial difficulty (OR=1·8 and 1·3 for women with severe and some financial difficulty, respectively, compared with none) and European language other than English spoken at home (OR=1·5 for European compared with Australian/English) were associated with higher prevalence of binge eating. Furthermore, longitudinal analyses indicated increased risk of persistent binge eating among women with a history of being overweight in childhood, those residing in metropolitan Australia, women with higher BMI, smokers and binge drinkers. Overeating, binge eating and symptoms of bulimia nervosa are common among young Australian women and cluster with binge drinking. Perceived financial stress appears to increase the risk of binge eating and bulimia nervosa. It is unclear whether women of European origin and those with a history of childhood overweight carry higher risk of binge eating because of genetic or cultural reasons.

    Approximately 1/5 of adolescents develop depressive symptoms. Given that youths spend a good deal of their lives at school, it seems plausible that supportive relationships with teachers could benefit their emotional well-being. Thus, the purpose of this study is to examine the association between emotionally supportive teacher relationships and depression in adolescence. The so-called principle-effect and stress-buffer models could explain relationships between teacher emotional support and depressive symptoms, yet no study has used both models to test bidirectional relationships between teacher support and depressive symptoms in students separately by sex. Four-thousand three-hundred forty-one students (boys: n = 2,063; girls: n = 2,278) from Grades 8 to 12 completed the Center for Epidemiological Studies Depression Scale (CES-D), List of Threatening Experiences Questionnaire (LTEQ), and an instrument developed for the study to measure teacher support annually for 5 years. Results support neither of the 2 proposed models. Instead, they indicate that in the 1st years of high school, students of both sexes with average and high numbers of stressful events benefit from teacher support, while teacher support might have iatrogenic effects on students experiencing low numbers of stressful events. Possible explanations for the findings and future research are discussed.

    In many industrialised countries teenage pregnancy and teenage parenthood have in recent years been identified as social and public health problems that need to be tackled. A number of studies have looked at various outcomes for teenage mothers and their offspring, and many report a strong association with poverty for the mother both before and after having a child. Few studies, however, adequately control for socioeconomic circumstances when examining health and related outcomes. Most studies have focused on perinatal outcomes in the offspring with few looking at later health and development. In Australia, where the rate of teenage pregnancy is relatively high compared to other comparable countries, teenage pregnancy is a not prominent policy concern. As such, Australia offers the opportunity to study the outcomes of teenage parenthood in a country where there may be less stigma than in countries that portray teenage parenthood as a major health and/or social problem. This paper reports findings from the Mater-University Study of Pregnancy (MUSP) and its outcomes, a prospective study of women, and their offspring, who received antenatal care at a major public hospital (Mater Misericordiae Hospital) in South Brisbane, Australia, between 1981 and 1984. We have examined the associations of maternal age (18 years (n=4800)) at first antenatal visit with offspring psychological, behavioural and health characteristics when the offspring--the teenage children of teenage mothers--were aged 14 years. Multiple logistic regression was used to determine the effect of maternal and family characteristics on associations between maternal age and childhood outcomes at age 14. Results show that the 14 year old offspring of mothers who were aged 18 years and younger compared to those who were offspring of older mothers were more likely to have disturbed psychological behaviour, poorer school performance, poorer reading ability, were more likely to have been in contact with the

    Price boards in tobacco retailers are one of the few forms of tobacco promotion remaining in Australia. This study aimed to examine how these boards were used to promote products over a period of rapidly rising taxes. Observations were made in a panel of 350 stores in Melbourne, Australia, in November of 2013 (just before) and in 2014 and 2015 (after 12.5% increases in tobacco duty). Fieldworkers unobtrusively noted the presence and characteristics of price boards, and the brand name, size and price of the product at the top of each board. Price boards were common in all store types apart from newsagent/lottery agents. The characteristics of the top-listed product changed notably over time: premium brands accounted for 66% of top-listed products in 2013, significantly declining to 43% in 2015, while packs of 20 cigarettes increased in prominence from 32% to 45%. The prevalence of packs of 20 cigarettes in budget market segments tripled from 2013 (13%) and 2014 (11%) to 32% in 2015, with no change in the proportion of packs that were under $A20 from 2014 (37%) to 2015 (36%). The rate of increase in the average price of the top-listed pack correspondingly flattened from 2014 to 2015 compared with 2013-2014. Price boards promote tobacco products in ways that undermine the effectiveness of tax policy as a means of discouraging consumption. Communication to consumers about prices should be restricted to information sheets provided to adult smokers on request at the point of sale. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Neither subjective memory beliefs, nor remembering itself, can be isolated from the overall context in which one is aging, nor are the drivers of memory complaints well specified. Sense of control is an important self-regulatory resource that drives cognitive and physical health over the lifespan. Existing findings are equivocal concerning both the extent of stability or change in control beliefs over time as well as their contribution to changes in behavior. Subjective beliefs may play a role when engaging memory processes or identifying memory complaints, and it has been argued that self-regulatory potential in general may be limited by age-related changes in the domains of health and cognition. We aimed to examine trajectories of change and shed light on relationships among subjective beliefs and indicators of memory and functional health. Participants' data were drawn from four measurement occasions over up to a 12-year period (1992-2004) from the Australian Longitudinal Study of Ageing (ALSA), a population-based study of older adults [age 65-100 years; mean age(SD) at the first and final occasion 78.2 (6.7) and 84.9 (4.9) years, respectively]. Participants completed three questionnaires assessing subjective beliefs concerning (1) memory knowledge and control, (2) health control, and (3) expectancy of control over a range of lifestyle situations. Memory comprised a recall composite. Functional health tapped mobility and disability. Latent growth curve models incorporated informative covariates (baseline age, gender, self-rated health, education, and chronic conditions). While subjective memory control beliefs, but not subjective knowledge of memory tasks, improved over 12 years, neither was associated with level of memory performance. Knowledge of memory tasks was linked to a significant memory decline. Beliefs about memory, health, and lifestyle were interrelated. Declines in remembering and health were also coupled; moreover, changes in both were coupled with

    There is evidence of a causal relationship between disability acquisition and poor mental health, but the substantial heterogeneity in the magnitude of the effect is poorly understood and may be aetiologically informative. This study aimed to identify demographic and socioeconomic factors that modify the effect of disability acquisition on mental health. The Household, Income and Labour Dynamics in Australia Survey is a nationally representative longitudinal survey of Australian households that has been conducted annually since 2001. Four waves of data were included in this analysis, from 2011 to 2014. Individuals who acquired a disability (n=387) were compared with those who remained disability-free in all four waves (n=7936). Mental health was measured using the mental health subscale of the Short Form 36 (SF-36) general health questionnaire, which measures symptoms of depression, anxiety and psychological well-being. Linear regression models were fitted to estimate the effect of disability acquisition on mental health, testing for effect modification by key demographic and socioeconomic characteristics. To maximise causal inference, we used a propensity score approach with inverse probability of treatment weighting to control for confounding and multiple imputation using chained equations to assess the impact of missing data. On average, disability acquisition was associated with a 5-point decline in mental health score (estimated mean difference: -5.1, 95% CI -7.2 to -3.0). There was strong evidence that income and relationship status modified the effect, with more detrimental effects in the lowest (-12.5, 95% CI -18.5 to -6.5) compared with highest income quintile (-1.1, 95% CI -4.9 to 2.7) and for people not in a relationship (-8.8, 95% CI -12.9 to -4.8) compared with those who were (-3.7, 95% CI -6.1 to -1.4). Our results suggest that the detrimental effect of disability acquisition on mental health is substantially greater for socioeconomic

    To investigate whether the total amount of time in childcare through the first 3 years of life was associated with children's receptive vocabulary, externalising and internalising problem behaviours at age 4-5 years, and whether this association varied for different types of childcare. We used data from the prospective, population-based Longitudinal Study of Australian Children (n=3208-4066, depending on outcome). Parental reports of the time spent in different types of childcare were collected at face-to-face interviews at age 0-1years and at age 2-3 years. Children's receptive vocabulary was directly assessed in the child's home, and externalising and internalising behaviours were measured by questionnaire, completed by parents and teachers at age 4-5 years. At 3 years of age, 75% of the sample spent regular time in the care of someone other than the parent. After adjustment, more time in childcare was not associated with children's receptive vocabulary ability but was associated with higher levels of parent-reported (β=0.10 (95% CI 0.00 to 0.21)) and teacher-reported (β=0.31 (0.19 to 0.44)) externalising problem behaviours and lower levels of parent-reported internalising problem behaviours (β=-0.08 (-0.15 to -0.00)). Compared with children who did not attend any type of childcare, children in centre-based care had higher parent-reported and teacher-reported externalising and lower internalising problem behaviours. More time in centre-based childcare (but not other types of care) through the first 3 years of life was associated with higher parent-reported and teacher-reported externalising problem behaviours, and lower parent-reported internalising problem behaviours but not with children's receptive vocabulary ability at school entry.

    The aim of this study is to use national Australian time-diary data to examine both (1) cross-sectionally and (2) longitudinally whether being late versus early to sleep or wake is associated with poorer child behavior, quality of life, learning, cognition and weight status, and parental mental health. Data from the first three waves of the Longitudinal Study of Australian Children were taken. A national representative sample of 4983 4-5-year-olds, recruited in 2004 from the Australian Medicare database and followed up biennially, was taken; 3631 had analyzable sleep information and a concurrent measure of health and well-being for at least one wave. Parents completed 24-h child time-use diaries for one week and one weekend day at each wave. Using median splits, sleep timing was categorized into early-to-sleep/early-to-wake (EE), early-to-sleep/late-to-wake (EL), late-to-sleep/early-to-wake (LE), and late-to-sleep/late-to-wake (LL) at each wave. The outcomes included parent-reported child behavior, health-related quality of life, maternal/paternal mental health, teacher-reported child language, literacy, mathematical thinking, and approach to learning. The study assessed child body mass index and girth. (1) Using EE as the comparator, linear regression analyses revealed that being late-to-sleep was associated with poorer child quality of life from 6 to 9 years and maternal mental health at 6-7 years. There was inconsistent or no evidence for associations between sleep timing and all other outcomes. (2) Using the count of the number of times (waves) at which a child was categorized as late-to-sleep (range 0-3), longitudinal analyses demonstrated that there was a cumulative effect of late-to-sleep profiles on poorer child and maternal outcomes at the child age of 8-9 years. Examined cross-sectionally, sleep timing is a driver of children's quality of life and maternal depression. Examined longitudinally, there appears to be cumulative and adverse relationships

    Full Text Available Abstract Background While there is considerable research on medical workforce supply trends, there is little research examining the determinants of labour supply decisions for the medical workforce. The "Medicine in Australia: Balancing Employment and Life (MABEL" study investigates workforce participation patterns and their determinants using a longitudinal survey of Australian doctors. It aims to generate evidence to support developing effective policy responses to workforce issues such as shortages and maldistribution. This paper describes the study protocol and baseline cohort, including an analysis of response rates and response bias. Methods/Design MABEL is a prospective cohort study. All Australian doctors undertaking clinical work in 2008 (n = 54,750 were invited to participate, and annual waves of data collections will be undertaken until at least 2011. Data are collected by paper or optional online version of a questionnaire, with content tailored to four sub-groups of clinicians: general practitioners, specialists, specialists in training, and hospital non-specialists. In the baseline wave, data were collected on: job satisfaction, attitudes to work and intentions to quit or change hours worked; a discrete choice experiment examining preferences and trade-offs for different types of jobs; work setting; workload; finances; geographic location; demographics; and family circumstances. Discussion The baseline cohort includes 10,498 Australian doctors, representing an overall response rate of 19.36%. This includes 3,906 general practitioners, 4,596 specialists, 1,072 specialists in training, and 924 hospital non-specialists. Respondents were more likely to be younger, female, and to come from non-metropolitan areas, the latter partly reflecting the effect of a financial incentive on response for doctors in remote and rural areas. Specialists and specialists in training were more likely to respond, whilst hospital non-specialists were less

    Better diets, as evaluated by diet quality indices, are associated with lower rates of morbidity and mortality. Although governments and researchers alike recognise the burden that obesity incurs for increased healthcare spending, there is insufficient evidence for the role of diet quality on healthcare costs. Diet quality was assessed by the Australian Recommended Food Score (ARFS) for 6328 women aged 50-55 years from the Australian Longitudinal Study on Women's Health. The ARFS was ranked by quintile, and 10-year cumulative data on healthcare costs from Medicare (Australia's Universal healthcare cover) were reported by body mass index category, using generalised linear modelling. Healthy weight women with the highest diet quality were found to make significantly fewer Medicare claims (P = 0.012) compared to those with the lowest diet quality. In healthy weight and overweight women, the number of healthcare claims and charges was inversely associated with consuming a greater variety of vegetables. For every 1 point increase in the ARFS vegetable component score, healthy weight women made 1.9 fewer healthcare claims and were charged $139 less, whereas overweight women made 2.3 fewer claims and were charged $176 less for healthcare over 10 years. The results of the present study support the need to prioritise an improved diet quality with the aim of reducing healthcare claims and overall costs in a population-based sample of Australian females. As the burden of overweight and obesity on the healthcare system increases, strategies to improve diet quality may be of particular importance; however, more research is required to further establish this relationship. © 2018 The British Dietetic Association Ltd.

  6. Patterns of Multiple Risk Exposures for Low Receptive Vocabulary Growth 4-8 Years in the Longitudinal Study of Australian Children.

    Directory of Open Access Journals (Sweden)

    Daniel Christensen

    Full Text Available Risk exposures and predictions of child development outcomes typically estimate the independent effects of individual exposures. As a rule though, children are not exposed piecemeal to individual or single risks but, rather, they are exposed to clusters of risk. Many of these clusters of risks are better thought of as comprising a developmental "circumstance" with a substantial duration, over which period, additional risk exposures also accumulate. In this paper we examined the distribution of 16 single risk exposures for low language ability using latent class analysis across a sample of approximately 4000 children from the Longitudinal Study of Australian Children. The best fitting model identified six distinct classes. 46% of children were in a Developmentally Enabled group, 20% were in a group typified as Working Poor families, 10% of children were in group typified as Overwhelmed group, 9% of children were in a group defined by Child Developmental Delay, 8% of children were in a group defined by Low Human Capital, and 7% of children were in a group defined by Resource Poor non-English Speaking background families. These groups had quantitatively and qualitatively distinct patterns of risk factors and showed different onward trajectories of receptive vocabulary. Our results demonstrate a range of multiple risk profiles in a population-representative sample of Australian children and highlight the mix of risk factors faced by children. Children with distinct patterns of risk factors have different onward trajectories of receptive vocabulary development.

    Despite cross-sectional evidence of a link between TV viewing and BMI in early childhood, there has been limited longitudinal exploration of this relationship. The aim of the present study was to explore the potential bi-directionality of the relationship between TV viewing and child BMI. A secondary aim was to evaluate whether this relationship is mediated by dietary intake. Parents of 9064 children (4724 recruited at birth, 4340 recruited at age 4) from the Longitudinal Study of Australian Children (LSAC) completed measures of their child's dietary intake and TV viewing habits at three equidistant time points, separated by 2years. Objective measures of height and weight were also obtained at each time point to calculate BMI. Cross-lagged panel analyses were conducted to evaluate potential bi-directional associations between TV viewing and child BMI, and to evaluate mediation effects of dietary intake for this relationship. Our longitudinal findings suggest that the relationship between TV viewing and BMI is bi-directional: Individuals who watch TV are more likely to gain weight, and individuals who are heavier are also more likely to watch TV. Interestingly, dietary intake mediated the BMI-TV viewing relationship for the older children, but not for the birth cohort. Present findings suggest that sedentary behaviours, particularly when coupled with unhealthy dietary habits, constitute a significant risk factor for excessive weight gain in early childhood. Interventions targeted at helping parents to develop healthy TV viewing and eating habits in their young children are clearly warranted. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Studies have documented the perceived needs of carers of people with psychosis but most recruitment has utilised convenience sampling resulting in limited understanding of carers' needs. This longitudinal study was conducted within the second Australian prevalence study of psychosis, aiming to obtain generalisable findings regarding perceived needs of carers of people with psychosis. Semi-structured interviews were conducted with 98 carers of people with psychosis recruited in the Australian prevalence study of psychosis. Seventy-eight of the carers were reinterviewed 1 year later to measure changes in their perceived needs. Correlational and paired T tests were conducted to identify relationships between perceived needs and carer's health and well-being, and changes in levels of perceived needs over time. Qualitative responses were structurally coded by segmentation according to the Carers' and Users' Expectations of Services-Carer version. Thematic analysis of common words and phrases was undertaken to identify key themes concerning carers' perceived needs. There was minimal improvement in carers' perceived needs over time and their needs were closely related to their perception of their own social connectedness, psychological health and quality of life. Five themes were identified: Greater involvement of carers in the treatment plan, provision of relevant information to carers, multiple biopsychosocial support for carers, well-being and independence interventions for people with psychosis, and choice to care and alternate caring arrangements. Although policy recognises the need to support carers, findings show that focused interventions are required to address carers' perceived needs more holistically in current mental health services. To support carers' recovery, services need to include carers in treatment planning, and consider ways to address their needs and improve their own health and well-being. © 2017 John Wiley & Sons Ltd.

    To investigate how SF-6D utility scores change with age between generations of women and to quantify the relationship of SF-6D with lifestyle factors across life stages. Up to seven waves of self-reported, longitudinal data were drawn for the 1973-1978 (young, N = 13772), 1946-1951 (mid-age, N = 12792), 1921-1926 (older, N = 9972) cohorts from the Australian Longitudinal Study on Women's Health. Mixed effects models were employed for analysis. Young and mid-age women had similar average SF-6D scores at baseline (0.63-0.64), which remained consistent over the 16-year period. However, older women had lower scores at baseline at 0.57 which steadily declined over 15 years. Across cohorts, low education attainment, greater difficulty in managing income, obesity, physical inactivity, heavy smoking, no alcohol consumption, and increasing stress levels were associated with lower SF-6D scores. The magnitude of effect varied between cohorts. SF-6D scores were lower amongst young women with high-risk drinking behaviours than low-risk drinkers. Mid-age women, who were underweight, never married, or underwent surgical menopause also reported lower SF-6D scores. Older women who lived in remote areas, who were ex-smokers, or were underweight, reported lower SF-6D scores. The SF-6D utility score is sensitive to differences in lifestyle factors across adult life stages. Gradual loss of physical functioning may explain the steady decline in health for older women. Key factors associated with SF-6D include physical activity, body mass index, menopause status, smoking, alcohol use, and stress. Factors associated with poorer SF-6D scores vary in type and magnitude at different life stages.

  10. The impact of socioeconomic status on changes in the general and mental health of women over time: evidence from a longitudinal study of Australian women

    2013-01-01

    Introduction Generally, men and women of higher socioeconomic status (SES) have better health. Little is known about how socioeconomic factors are associated with changes in health as women progress through mid-life. This study uses data from six survey waves (1996 to 2010) of the Australian Longitudinal Study on Women’s Health (ALSWH) to examine associations between SES and changes in the general health and mental health of a cohort of women progressing in years from 45–50 to 59–64. Methods Participants were 12,709 women (born 1946–51) in the ALSWH. Outcome measures were the general health and mental health subscales of the Medical Outcomes Study Short Form 36 Questionnaire (SF-36). The measure of SES was derived from factor analysis of responses to questions in the ALSWH baseline survey (1996) on school leaving age, highest qualifications, and current or last occupation. Multi-level random coefficient models, adjusted for socio-demographic factors and health behaviors, were used to analyze repeated measures of general health and mental health. Survey year accounted for changes in factors across time. In the first set of analyses we investigated associations between the SES index, used as a “continuous” variable, and general health and mental health changes over time. To illuminate the impact of different levels of SES on health, a second analysis was conducted in which SES scores were grouped into three approximately equal sized categories or “tertiles” as reported in an earlier ALSWH study. The least square means of general and mental health scores from the longitudinal models were plotted for the three SES tertiles. Results The longitudinal analysis showed that, after adjusting for the effects of time and possible confounders, the general (mental) health of this cohort of mid-aged women declined (increased) over time. Higher SES women reported better health than lower SES women, and SES significantly modified the effects of time on both general

    Full Text Available Data from the Australian Longitudinal Study on Women’s Health were used to examine how work was associated with time spent sleeping, sitting and in physical activity (PA, in working women. Young (31–36 years; 2009 and mid-aged (59–64 years; 2010 women reported sleep (categorised as shorter ≤6 h/day and longer ≥8 h/day and sitting time (work, transport, television, non-work computer, and other; summed for total sitting time on the most recent work and non-work day; and moderate and vigorous PA (categorised as meeting/not meeting guidelines in the previous week. Participants reported occupation (manager/professional; clerical/sales; trades/transport/labourer, work hours (part-time; full-time and work pattern (shift/night; not shift/night. The odds of shorter sleep on work days was higher in both cohorts for women who worked shift or night hours. Longer sitting time on work days, made up primarily of sitting for work, was found for managers/professionals, clerical/sales and full-time workers. In the young cohort, clerical/sales workers and in the mid-aged cohort, full-time workers were less likely to meet PA guidelines. These results suggest multiple behaviour interventions tailored to work patterns and occupational category may be useful to improve the sleep, sitting and activity of working women.

    The study of sedentary behavior is a relatively new area in population health research, and little is known about patterns of sitting time on week-days and weekend-days. To compare self-reported week-day and weekend-day sitting time with reported weekly time spent in other activities. Data were from 8,717 women born between 1973 and 1978 ('younger'), and 10,490 women born between 1946 and 1951 ('mid-age') who completed surveys for the Australian Longitudinal Study on Women's Health in 2003 and 2001, respectively. They were asked about time spent sitting on week-days and weekend-days. The women were also asked to report time spent in employment, active leisure, passive leisure, home duties, and studying. Mean week-day and weekend-day sitting times were compared with time-use using analysis of variance. Younger women sat more than mid-aged women, and sitting time was higher on week-days than on weekend-days in both cohorts. There were marked positive associations between week-day and weekend-day sitting times and time spent in passive leisure in both cohorts, and with time spent studying on week-days for the younger women. Week-day sitting time was markedly higher in women who reported >35 h in employment, compared with those who worked day sitting time was higher than weekend-day sitting time, the patterns of the relationships between week-day and weekend-day sitting and time-use were largely similar, except for time spent in employment.

    Receptive vocabulary development is a component of the human language system that emerges in the first year of life and is characterised by onward expansion throughout life. Beginning in infancy, children's receptive vocabulary knowledge builds the foundation for oral language and reading skills. The foundations for success at school are built early, hence the public health policy focus on reducing developmental inequalities before children start formal school. The underlying assumption is that children's development is stable, and therefore predictable, over time. This study investigated this assumption in relation to children's receptive vocabulary ability. We investigated the extent to which low receptive vocabulary ability at 4 years was associated with low receptive vocabulary ability at 8 years, and the predictive utility of a multivariate model that included child, maternal and family risk factors measured at 4 years. The study sample comprised 3,847 children from the first nationally representative Longitudinal Study of Australian Children (LSAC). Multivariate logistic regression was used to investigate risks for low receptive vocabulary ability from 4-8 years and sensitivity-specificity analysis was used to examine the predictive utility of the multivariate model. In the multivariate model, substantial risk factors for receptive vocabulary delay from 4-8 years, in order of descending magnitude, were low receptive vocabulary ability at 4 years, low maternal education, and low school readiness. Moderate risk factors, in order of descending magnitude, were low maternal parenting consistency, socio-economic area disadvantage, low temperamental persistence, and NESB status. The following risk factors were not significant: One or more siblings, low family income, not reading to the child, high maternal work hours, and Aboriginal or Torres Strait Islander ethnicity. The results of the sensitivity-specificity analysis showed that a well-fitted multivariate model

    This study aimed to identify distinct developmental trajectories (sub-groups of individuals who showed similar longitudinal patterns) of cannabis use among Australian adolescents, and to examine associations between trajectory group membership and measures of social and behavioural adjustment in young adulthood. Participants (n=852, 53% female) were part of the International Youth Development Study. Latent class growth analysis was used to identify distinct trajectories of cannabis use frequency from average ages 12 to 19, across 6 waves of data. Logistic regression analyses and analyses of covariance were used to examine relationships between trajectory group membership and young adult (average age: 21) adjustment, controlling for a range of covariates. Three trajectories were identified: abstainers (62%), early onset users (11%), and late onset occasional users (27%). The early onset users showed a higher frequency of antisocial behaviour, violence, cannabis use, cannabis-related harms, cigarette use, and alcohol harms, compared to the abstinent group in young adulthood. The late onset occasional users reported a higher frequency of cannabis use, cannabis-related harms, illicit drug use, and alcohol harms, compared to the abstinent group in young adulthood. There were no differences between the trajectory groups on measures of employment, school completion, post-secondary education, income, depression/anxiety, or alcohol use problems. In conclusion, early onset of cannabis use, even at relatively low frequency during adolescence, is associated with poorer adjustment in young adulthood. Prevention and intervention efforts to delay or prevent uptake of cannabis use should be particularly focussed on early adolescence prior to age 12. Copyright © 2015 Elsevier Ltd.

    We examine timing of motherhood in a longitudinal cohort of young Australian women, and its relationship with mental health-related quality of life (SF-36 MHI-5), and with sociodemographic, health behaviour and health-related variables. We analysed longitudinal self-report data from a nationally representative cohort of 10,332 Australian women born 1973-1978, surveyed 6 times between 1996 (aged 18-23) and 2012 (aged 34-39). Group-based trajectory modelling identified four groups. Normative Mothers (46%, mean age at motherhood 30.5 years) made the transition to motherhood close to the Australian median age. Early Mothers (25%, 25.2 years) and Very Early Mothers (7%, 20.0 years) made this transition earlier; Not Mothers (22%) had not given birth. Generalised linear mixed models showed that all groups improved mean MHI-5 scores over time. Patterns of group differences were complex: Normative and Early Mothers scored consistently highest; Very Early Mothers scored lowest at most surveys; Not Mothers' scores increased relative to others over time. Most effects disappeared after adjustment for confounders. Early and Very Early Mothers showed multiple indicators of social disadvantage, while Not Mothers had very low rates of marriage. Timing of motherhood is embedded in sociodemographic and personal contexts. Women with socioeconomic advantages were characterised by higher mental health-related quality of life and later transition to motherhood, but adjustment for relative advantage attenuated differences in mental health-related quality of life. The overall findings suggest a pattern of positive adaptation to circumstances, with mental health-related quality of life improving through early adulthood regardless of timing of motherhood.

    Despite advancements in our understanding of the importance of stress reduction in achieving good health, we still only have limited insight into the impact of stress on cellular function. Recent studies have suggested that exposure to prolonged psychological stress may alter an individual's physiological responses, and contribute to morbidity and mortality. This paper presents an overview of the study protocol we are using to examine the impact of life stressors on lifestyle factors, health-related quality of life and novel and established biomarkers of stress in midlife and older Australian women.The primary aim of this study is to explore the links between chronic psychological stress on both subjective and objective health markers in midlife and older Australian women. The study examines the extent to which exposure frightening, upsetting or stressful events such as natural disasters, illness or death of a relative, miscarriage and relationship conflict is correlated with a variety of objective and subjective health markers. This study is embedded within the longitudinal Healthy Aging of Women's study which has collected data from midlife and older Australian women at 5 yearly intervals since 2001, and uses the Allostastic model of women's health by Groër and colleagues in 2010. The current study expands the focus of the HOW study and will assess the impact of life stressors on quality of life and clinical biomarkers in midlife and older Australian women to explain the impact of chronic psychological stress in women. The proposed study hypothesizes that women are at increased risk of exposure to multiple or repeated stressors, some being unique to women, and the frequency and chronicity of stressors increases women's risk of adverse health outcomes. This study aims to further our understanding of the relationships between stressful life experiences, perceived quality of life, stress biomarkers, chronic illness, and health status in women.

  1. Poor adherence to national and international breastfeeding duration targets in an Australian longitudinal cohort.

    Directory of Open Access Journals (Sweden)

    Alexis J Hure

    Full Text Available OBJECTIVES: To report on the proportion and characteristics of Australian infants who are fed, and mothers who feed, in accordance with the national and international breastfeeding duration targets of six, 12 and 24 months. Furthermore, to examine the longitudinal breastfeeding duration patterns for women with more than one child. METHODS: Breastfeeding duration data for 9773 children have been self-reported by a national sample of 5091 mothers aged 30-36 years in 2009, participating in the Australian Longitudinal Study on Women's Health. RESULTS: Only 60% of infants received the minimum recommended 6 months of breast milk, irrespective of breastfeeding exclusivity. Less than 30% of infants received any breast milk at 12 months, and less than 3% were breastfed to the international target of 24 months. Young, less educated, unmarried or low-income women were at an increased risk of premature breastfeeding cessation. For women with three or more children, nearly 75% of women who breastfed their first child for at least six months reached this breastfeeding duration target for their next two children. CONCLUSION: While national breastfeeding rates are typically evaluated in relation to the infant, a novel component of our study is that we have assessed maternal adherence to breastfeeding duration targets and the longitudinal feeding practices of women with more than one child. Separate evaluations of maternal and infant breastfeeding rates are important as they differ in their implications for public health policy and practice.

    Full Text Available There is considerable public health interest in understanding what factors during adolescence predict longer-term drinking patterns in adulthood. The aim of this study was to examine gender differences in the age 15 social and psychological predictors of less healthy drinking patterns in early adulthood. The study investigates the relative importance of internalising problems, other risky health behaviours, and peer relationships after controlling for family background characteristics. A sample of 812 young people who provided complete alcohol consumption data from the age of 15 to 20 years (5 measurement points were drawn from South Australian secondary schools and given a detailed survey concerning their psychological and social wellbeing. Respondents were classified into two groups based upon a percentile division: those who drank at levels consistently below NHMRC guidelines and those who consistently drank at higher levels. The results showed that poorer age 15 scores on measures of psychological wellbeing including scores on the GHQ-12, self-esteem, and life-satisfaction as well as engagement in health-related behaviours such as smoking or drug-taking were associated with higher drinking levels in early adulthood. The pattern of results was generally similar for both genders. Higher drinking levels were most strongly associated with smoking and marijuana use and poorer psychological wellbeing during adolescence.

    This paper investigated distinct longitudinal trajectories of absenteeism over time, and underlying demographic, work, and health antecedents. Data from the Household, Income, and Labor Dynamics in Australia Survey were used; this is a panel study of a representative sample of Australian households. This paper focused on 2,481 full-time employees across a 5-year period. Information on annual sick leave and relevant sociodemographic, work, and health-related factors was collected through interviews and self-completed surveys. Growth mixture modeling indicated 4 distinct longitudinal patterns of absenteeism over time. The moderate absenteeism trajectory (34.8%) of the sample had 4-5 days of sick leave per year and was used as the reference group. The low absenteeism trajectory (33.5%) had 1-2 days of absenteeism per year, while the no absenteeism trajectory (23.6%) had very low rates of absenteeism (absenteeism (>11 days per year). Compared with the moderate absenteeism trajectory, the high absenteeism trajectory was characterized by poor health; the no absenteeism and low absenteeism trajectories had better health but may also reflect processes relating to presenteeism. These results provide important insights into the nature of absenteeism in Australian employees, and suggest that different patterns of absenteeism over time could reflect a range of demographic, work, and health related factors.

    Vocabulary is a key component of language that can impact on children's future literacy and communication. The gap between Australian Aboriginal and non-Aboriginal children's reading and academic outcomes is well reported and similar to Indigenous/non-Indigenous gaps in other nations. Determining factors that influence vocabulary acquisition over time and may be responsive to treatment is important for improving Aboriginal children's communication and academic outcomes. To determine what factors influence Australian urban Aboriginal children's receptive vocabulary acquisition and whether any of these are risks or protective for vocabulary development. One hundred thirteen Aboriginal children in South Western Sydney from the longitudinal birth cohort Gudaga study were assessed on The Peabody Picture Vocabulary Test multiple times: 3 years, just prior to school entry, at the end of the first and second years of formal schooling. Multilevel models were used to determine the effects of 13 fixed and manipulable maternal, child, and family variables drawn from previous research. Higher maternal education was found to be protective at 3 years and over time. The number of children in urban Australian Aboriginal households made an impact on vocabulary development and this varied over time. From 3 to 6 years, those with early poor non-verbal cognitive skills had vocabulary skills that remained below those with stronger non-verbal skills at 3 years. Girls exhibit an earlier advantage in vocabulary acquisition, but this difference is not sustained after 4 years of age. The risk and protective factors for vocabulary development in Australian Aboriginal children are similar to those identified in other studies with some variation related to the number of children in the home. In this limited set of predictors, maternal education, gender, non-verbal cognitive skills, and the number of children in households were all shown to impact on the acquisition of vocabulary to 3

    Objective There is robust epidemiological and clinical evidence of the harmful effects of unemployment on psychological well-being, but the mechanisms through which this occurs is still strongly debated. In addition, there is even less evidence on the impact of underemployment on mental health. Using longitudinal data collected from a cohort of 20–24 years old, the present study examines a range of employed states and investigates the role of mastery, financial hardship and social support in the relationship between labour status and depression. Method Responses were from the Personality and Total Health (PATH) Through Life Project: A representative, community-based survey conducted in Canberra and Queanbeyan (NSW) in Australia, where respondents (n=2404) in their early twenties were followed for 8 years. Depression was measured using the self-report Goldberg Depression Scale, with the likely presence of depression being indicated by scores 7 or greater. Results The analyses identified unemployment and underemployment as significant predictors of depression, compared to their employed counterparts. Both unemployment and underemployment remained significantly correlated with depression even after accounting for sociodemographic, economic and psychological variables. Social support, financial hardship and a sense of personal control (mastery) all emerged as important mediators between unemployment and depression. Conclusions Both unemployment and underemployment were associated with increased risk of depression. The strength of this relationship was attenuated but remained significant after accounting for key variables (mastery, financial hardship and social support), and extensive sociodemographic and health covariates, indicating that no or inade­quate employment contributes to poorer mental health over and above these factors.

    Geography remains a critical factor that shapes the development of aspirations, attainment, and choice in young people. We focus on the role of geography on university entry and aspirations due to the increasing requirement in society for a higher education qualification for access to prestigious positions in society. Using a large representative longitudinal database (N = 11,999; 50 % male; 27 % provincial or rural; 2 % Indigenous) of Australia youth we explore the association between distance to a university campus and the critical attainment outcomes of university entry and enrolment in an elite university as well as critical predictors of these outcomes in access to information resources (i.e., university outreach programs) and university aspirations. In doing so, we provide new insight into distance effects, and the extent that these are due to selection, cost, and community influence. Our findings suggest that distance is significantly associated with both university expectations and entrance, with an especially large impact upon young people from low socioeconomic backgrounds. However, we also find little evidence that distance is related to attending a university led information session. Our conclusion is that distance effects cannot be fully explained by selection in terms of academic achievement and socioeconomic status, and that anticipatory decisions and costs are the most likely drivers of the distance effect.

    Towards the end of 2015 and during 2016 there were exten-sive studies of longitudinal beam dynamics in LEIR aimedat improving extracted intensities. As the driving source oflosses early in the ramp was shown to be transverse spacecharge tune spread a significant improvement came fromflattening the beam profile to increase the bunching factorby offsetting the RF frequency from the beam revolution fre-quency. Further benefits were provided by modulating theRF frequency during capture, leading to emittance blow-upand improved reproducibility. The use of two RF cavitiesduring operation was studied to try and further increase thecaptured emittance, however after careful alignment of theRF it was found that a hard limit in the bunch heigh of approx-imately 7 MeV exists. Due to the acceptance limit there wasno operational benefit to using both cavities simultaneously

    A primary societal goal for aging is enabling older people to continue to live well as long as possible. The evidence base around aging well ("healthy," "active," and "successful" aging) has been constructed mainly from academic and professional conceptualizations of mortality, morbidity, functioning, and psychological well-being with some attention to lay views. Our study aims to inform action on health promotion to achieve aging well as conceptualized by qualitative research identifying what older Australians themselves value most: continuing to live as long as possible in the community with independence in daily living, and good self-rated health and psychological well-being. Multivariate survival analyses from the Melbourne longitudinal studies on healthy aging program found that important threats to aging well for the total sample over a 12-year period were chronological age, multi-morbidity, low perceived social support, low nutritional score, and being under-weight. For men, threats to aging well were low strain, perceived inadequacy of social activity, and being a current smoker. For women, urinary incontinence, low physical activity and being under-weight were threats to aging well. The findings indicate that healthy lifestyles can assist aging well, and suggest the value of taking gender into account in health promotion strategies.

    Internationally, men with disabilities have higher rates of social and economic disadvantage and poorer health and wellbeing than men without disabilities. No single study has provided comprehensive, population-level information about the magnitude of such differences among adult men using a well-validated instrument to measure disability. We analysed baseline data from Ten to Men - an Australian longitudinal study of male health. Ten to Men used a stratified multi-stage cluster random sample design to recruit a national sample of males aged 10 to 55 years residing in private dwellings. Data were collected between October 2013 and July 2014 from 15,988 males. This analysis was restricted to 18-55 year old participants with data available on age and disability (n = 13,569). We compared the demographic, socio-economic characteristics and health and wellbeing of men with and without disabilities using chi squared tests for proportions and t tests for continuous variables. Linear regression adjusted for age was used to assess the association between disability status and health and wellbeing, which were measured using the SF-12 mental and physical health component scores and the Personal Wellbeing Index. Men with disabilities were older and more likely to be born in Australia, speak English at home, be Aboriginal and Torres Strait Islander and were less likely to be married or de facto, or to live in urban areas. They were less likely to have completed secondary school, be employed and live in affordable housing, and were more likely to live on low incomes, in more socio-economically disadvantaged areas, and in rental accommodation and to experience shortages of money. Among employed men, those with disabilities were less likely to be in high skilled jobs, worked less hours on average, and were more likely to report that they would prefer to work more.

    In this paper we present a method for processing EHR data into a longitudinal data model and examples for using this model to identify patients cross-sectionally and longitudinally as well as testing study designs retrospectively. Our data model describes measurements on four dimensions: the associated patient, observed feature, data source and time of survey. The transformation of structured source data into our model is defined by rules written in XML. To showcase the flexibility of the proposed longitudinal data model, we present an evolution of a retrospective study design as well as an example for interpreting biomarkers in emergency situations. With the proposed longitudinal data model complex queries can be performed, study designs tested and optimized.

    Some studies suggest that cannabis use is associated with suicidal ideation, but no detailed longitudinal study has examined suicide as an outcome. To examine the association between cannabis use and completed suicide. A longitudinal study investigated 50 087 men conscripted for Swedish military service, with cannabis use measured non-anonymously at conscription. Suicides during 33 years of follow-up were identified by linkage with the National Cause of Death Register. There were 600 (1.2% of cohort) suicides or deaths from undetermined causes. Cannabis use was associated with an increased risk of suicide (crude OR for 'ever use' 1.62, 95% CI 1.28-2.07), but this association was eliminated after adjustment for confounding (adjusted OR = 0.88, 95% CI 0.65-1.20). Although there was a strong association between cannabis use and suicide, this was explained by markers of psychological and behavioural problems. These results suggest that cannabis use is unlikely to have a strong effect on risk of completed suicide, either directly or as a consequence of mental health problems secondary to its use.

  8. Longitudinal study of fingerprint recognition.

    2015-07-14

    Human identification by fingerprints is based on the fundamental premise that ridge patterns from distinct fingers are different (uniqueness) and a fingerprint pattern does not change over time (persistence). Although the uniqueness of fingerprints has been investigated by developing statistical models to estimate the probability of error in comparing two random samples of fingerprints, the persistence of fingerprints has remained a general belief based on only a few case studies. In this study, fingerprint match (similarity) scores are analyzed by multilevel statistical models with covariates such as time interval between two fingerprints in comparison, subject's age, and fingerprint image quality. Longitudinal fingerprint records of 15,597 subjects are sampled from an operational fingerprint database such that each individual has at least five 10-print records over a minimum time span of 5 y. In regard to the persistence of fingerprints, the longitudinal analysis on a single (right index) finger demonstrates that (i) genuine match scores tend to significantly decrease when time interval between two fingerprints in comparison increases, whereas the change in impostor match scores is negligible; and (ii) fingerprint recognition accuracy at operational settings, nevertheless, tends to be stable as the time interval increases up to 12 y, the maximum time span in the dataset. However, the uncertainty of temporal stability of fingerprint recognition accuracy becomes substantially large if either of the two fingerprints being compared is of poor quality. The conclusions drawn from 10-finger fusion analysis coincide with the conclusions from single-finger analysis.

    Work-family conflict (WFC) occurs when work or family demands are 'mutually incompatible', with detrimental effects on mental health. This study contributes to the sparse longitudinal research, addressing the following questions: Is WFC a stable or transient feature of family life for mothers and fathers? What happens to mental health if WFC increases, reduces or persists? What work and family characteristics predict WFC transitions and to what extent are they gendered? Secondary analyses of 5 waves of data (child ages 4-5 to 12-13 years) from employed mothers (n = 2693) and fathers (n = 3460) participating in the Longitudinal Study of Australian Children were conducted. WFC transitions, across four two-year intervals (Waves 1-2, 2-3, 3-4, and 4-5) were classified as never, conscript, exit or chronic. Significant proportions of parents experienced change in WFC, between 12 and 16% of mothers and fathers for each transition 'type'. Parents who remained in chronic WFC reported the poorest mental health (adjusted multiple regression analyses), followed by those who conscripted into WFC. When WFC was relieved (exit), both mothers' and fathers' mental health improved significantly. Predictors of conscript and chronic WFC were somewhat distinct for mothers and fathers (adjusted logit regressions). Poor job quality, a skilled occupation and having more children differentiated chronic fathers' from those who exited WFC. For mothers, work factors only (skilled occupation; work hours; job insecurity) predicted chronic WFC. Findings reflect the persistent, gendered nature of work and care shaped by workplaces, but also offer tailored opportunities to redress WFC for mothers and fathers. We contribute novel evidence that mental health is directly influenced by the WFC interface, both positively and negatively, highlighting WFC as a key social determinant of health. Copyright © 2016.

    To determine if differences in topographic progression between unaffected keratoconus relatives and normal controls can predict factors associated with the development of keratoconus in a longitudinal study. We recruited 369 unaffected keratoconus relatives and 119 normal controls in Los Angeles. Both eyes of subjects were examined at baseline clinically and by quantitative videokeratography and at a period ranging from 1 year to 8 years. Progression to keratoconus was evaluated by quantitative videokeratography variables. Unaffected relatives had higher Central K (CK), I-S and KISA values and were younger than normal controls (CK: 44.70 vs 44.01, Pkeratoconus (Pkeratoconus. After grouped unaffected relatives as the high risk (age=47.2 or I-S >=1.2 or KISA>=60) and the low risk (age>30 and Central Kkeratoconus quicker than normal controls. However, relatives in a high risk group may have a greater risk of progression to keratoconus. PMID:17681291

    In Victoria, schools are adopting one common certificate, the VCE (Victorian Certificate of Education) which encompasses two years of study (Years 11 and 12) and comprises 44 subject areas or Studies, each of one semester duration. Amongst the compulsory subjects is Australian Studies (Units 1 and 2) with its focus on Work in Australian society. This paper discusses concerns about the teaching of the compulsory subject Australian Studies in the new VCE. The purpose is to consider whether the science and technology component in the Australian Studies course can raise the students’ level of scientific and technological literacy. The discussion is based on one semester’s teaching experience of Year 11 Australian Studies and consequent reflections on practice.

    Full Text Available Missing data is a common problem in survey based research. There are many packages that compensate for missing data but few can easily compensate for missing longitudinal data. WinBUGS compensates for missing data using multiple imputation, and is able to incorporate longitudinal structure using random effects. We demonstrate the superiority of longitudinal imputation over cross-sectional imputation using WinBUGS. We use example data from the Australian Longitudinal Study on Women’s Health. We give a SAS macro that uses WinBUGS to analyze longitudinal models with missing covariate date, and demonstrate its use in a longitudinal study of terminal cancer patients and their carers.

    Our purpose was to determine if babies breastfed at 6 months of age were more likely to wake at night and less likely to sleep alone than formula-fed babies. Data were drawn from the first wave of The Longitudinal Study of Australian Children, an ongoing, nationally representative study of the growth and development of Australia's children. The 4507 participants met the criteria for this study. The measures examined infant sleep problems as the outcome and breastfeeding at 6 months of age as the exposure in addition to the demographic data, maternal mental health, infant birthweight and gestational age at delivery. After adjustment for covariates, reports by mothers of infants that breastfed at 6 months of age suggested infants were 66% more likely to wake during the night and 72% more likely to report difficulty sleeping alone. However, breastfeeding had a strongly protective effect on wheezing, coughing, snoring and breathing problems, and it was not associated with restless sleep or problems getting to sleep for the infant. Breastfeeding was found to be associated with increased night waking and this is consistent with other studies. There are biological reasons why this might be required to ensure breastfeeding continues to 6 months and beyond. The current low rates of sustained breastfeeding in many Western countries needs to be reconsidered in relation to parental and public health practices promoting prolonged nocturnal infant sleep patterns. © 2013 The Authors.

    The aims of this Australian study were to determine (total) selenium concentration in breast milk and in maternal blood, and to assess the relationship between the two. The authors also aimed to assess the infants' selenium intake. Twenty lactating women from Brisbane (Queensland) participated in the study, at 6-12 weeks post-partum. Small samples (approximately 10 ml) of breast-milk were manually expressed at the beginning and end of a mid-morning feed, from the first breast offered at that feed. Venous blood samples (10 ml) were also collected from the mothers. Milk and blood samples were analyzed by neutron activation analysis. Babies' milk intake over a 24-hour period was estimated using a modified test-weighing technique. Infant selenium intakes were calculated directly for each infant, using his/her mother's milk selenium level and his/her own 24-hour breast milk intake. The mean selenium concentration in maternal blood was 101 (±SD 19) ng/g and in maternal serum 81 (±15) ng/g. Breast milk selenium concentrations (11.9 ± 3.5 ng/g) were fairly low by international standards. There was no correlation between selenium concentrations in milk and blood (or serum). The infants' 24-hour breast-milk intakes were 856 ± 172 g, and their selenium intakes were 10.7 ± 4.1 μg per day

    Purpose Cyber bullying perpetration (using communication technology to engage in bullying) is a recent phenomenon that has generated much concern. There are few prospective longitudinal studies of cyber bullying. The current paper examines the individual, peer, family and school risk factors for both cyber and traditional bullying (the latter is bullying that does not utilize technology) in adolescents. Methods This paper draws on a rich data set from the International Youth Development Study, a longitudinal study of students in Victoria, Australia and Washington State, United States, which began in 2002. In this paper, data from almost 700 Victorian students recruited in Grade 5 is analyzed to examine Grade 7 (aged 12-13 years) predictors of traditional and cyber bullying perpetration in Grade 9 (aged 14-15 years). Results Fifteen per cent of students engaged in cyber bullying, 21% in traditional bullying and 7% in both. There are similarities and important differences in the predictors of cyber and traditional bullying. In the fully adjusted model, only prior engagement in relational aggression (a covert form of bullying such as spreading rumors about another student) predicted cyber bullying perpetration. For traditional bullying, previous relational aggression was also predictive, as was having been a victim and perpetrator of traditional bullying, family conflict, and academic failure. Conclusions The use of evidence-based bullying prevention programs is supported to reduce experiences of all forms of bullying perpetration(cyber, traditional, and relational aggression). In addition, for traditional bullying perpetration, addressing family conflict and student academic support are also important. PMID:22727078

    Ideally, life course data are collected prospectively through an ongoing longitudinal study. We report adaptive multimethod fieldwork procedures that gathered life history data by mail survey and telephone interview, comparable with the face-to-face methods employed in the English Longitudinal Study on Ageing (ELSA). The Australian Life Histories and Health (LHH) Survey was a substudy of the Australian 45 and Up Study, with data collection methods modified from the ELSA Study. A self-complete questionnaire and life history calendar were completed by the participants, followed by a computer-assisted telephone interview recording key life events. The LHH survey developed and tested procedures and instruments that gathered rich life history data within an ongoing Australian longitudinal survey on ageing. Data collection proved to be economical. The use of a self-complete questionnaire in conjunction with a life history calendar and coordinated computer-assisted telephone interview was successful in collecting retrospective life course information, in terms of being thorough, practical and efficient. This study has a diverse collection of data covering the life course, starting with early life experiences and continuing with socioeconomic and health exposures and outcomes during adult life. Mail and telephone methodology can accurately and economically add a life history dimension to an ongoing longitudinal survey. The method is particularly valuable for surveying widely dispersed populations. The results will facilitate understanding of the social determinants of health by gathering data on earlier life exposures as well as comparative data across geographical and societal contexts.

    2017-02-01

    We investigated the differences and over time changes in recommended physical activity among foreign-born (FB) from English speaking countries (ESC) and non-English speaking countries (NESC) relative to native-born (NB) Australians, and whether the association between nativity and duration of residence (DoR) and physical activity is mediated by English language proficiency, socioeconomic status and social engagement/membership. This study applies multilevel group-meancentered mixed (hybrid) logistic regression models to 12 waves of longitudinal data (12,634 individuals) from the Household, Income and Labor Dynamics in Australia survey with engagement in physical activities for more than 3 times a week as the outcome variable. Immigrants from ESC had higher odds of physical activity, while immigrants from NESC had significantly lower odds of physical activity than NB Australians, after adjusting for covariates. There was no evidence that these differences changed by DoR among immigrants from NESC, whereas ESC immigrants had higher odds of physical activity when their DoR was more than 20 years. We also found a mediating role of English language proficiency on immigrants physical activities. Appropriate health promotion interventions should be implemented to foster physical activities among NESC immigrants, considering English language proficiency as an important factor in designing interventions.

    Telford, Richard D; Cunningham, Ross B; Fitzgerald, Robert; Olive, Lisa S; Prosser, Laurence; Jiang, Xiaoli; Telford, Rohan M

    2012-02-01

    We determined whether physical education (PE) taught by specialists contributed to academic development and prevention of obesity in elementary school children. Our 2-year longitudinal study involved 620 boys and girls initially in grade 3 in Australia, all receiving 150 minutes per week of PE. One group (specialist-taught PE; n = 312) included 90 minutes per week of PE from visiting specialists; the other (common-practice PE; n = 308) received all PE from generalist classroom teachers. Measurements included percentage of body fat (measured by dual-emission x-ray absorptiometry) and writing, numeracy, and reading proficiency (by government tests). Compared with common-practice PE, specialist-taught PE was associated with a smaller increase in age-related percentage of body fat (P = .02). Specialist-taught PE was also associated with greater improvements in numeracy (P increases in percentage of body fat and enhanced numeracy development among elementary school children receiving PE from specialists provides support for the role of PE in both preventive medicine and academic development.

  8. How Australian and Indonesian Universities Treat Plagiarism: A Comparative Study

    Directory of Open Access Journals (Sweden)

    Bambang Yudi Cahyono

    2016-02-01

    Full Text Available This article is a part of a larger study comparing various aspects of policies on plagiarism in two university contexts. It compares policies on plagiarism in universities in Australia and Indonesia. The results of this comparative study showed that Australian and Indonesian universities treat plagiarism differently. Australian universities treat plagiarism explicitly in their university policies. In Australian universities, plagiarism is defined clearly and forms of plagiarism are explained thoroughly, policies on plagiarism are informed to all university academic members, and there are mechanisms to manage cases related to plagiarism. In contrast, not all Indonesian universities treat plagiarism directly. Some universities depend on religious morality and academic ethics in dealing with plagiarism. Accordingly, this article recommends the explicit treatment of plagiarism in Indonesian universities.

    2018-01-01

    Using the Longitudinal Surveys of Australian Youth (LSAY) data, this paper aimed to examine if, and to what extent, demographic factors predict students' participation in science over the age of 16 (post-16). While all the students participating in this study are attending Australian schools, the comprehensiveness of these datasets, together with inclusion of studies from around the world provides a useful reference point for an international audience. Over 7000 students are included in the analysis of this paper. Characteristics of focus in this paper include groups who have been identified as being underrepresented in past studies including Indigenous students, those from lower-socio-economic status (SES) backgrounds, sex differences and immigrants. Among the factors tested, Indigenous status was the strongest negative predictor of post-16 science participation. SES was also a relatively strong predictor of post-16 science participation. Compared to students categorised with an Australian-ancestry, first-generation and foreign-background students were more likely to participate in post-16 science. The findings of this study contribute to existing research on debates about equity and trends in science participation.

  11. Study of CSR longitudinal bunch compression cavity

    2009-01-01

    The scheme of longitudinal bunch compression cavity for the Cooling Storage Ring (CSR)is an important issue. Plasma physics experiments require high density heavy ion beam and short pulsed bunch,which can be produced by non-adiabatic compression of bunch implemented by a fast compression with 90 degree rotation in the longitudinal phase space. The phase space rotation in fast compression is initiated by a fast jump of the RF-voltage amplitude. For this purpose, the CSR longitudinal bunch compression cavity, loaded with FINEMET-FT-1M is studied and simulated with MAFIA code. In this paper, the CSR longitudinal bunch compression cavity is simulated and the initial bunch length of 238 U 72+ with 250 MeV/u will be compressed from 200 ns to 50 ns.The construction and RF properties of the CSR longitudinal bunch compression cavity are simulated and calculated also with MAFIA code. The operation frequency of the cavity is 1.15 MHz with peak voltage of 80 kV, and the cavity can be used to compress heavy ions in the CSR. (authors)

    To determine the incidence of and factors associated with vitamin D deficiency rickets in Australian children. 18-month questionnaire-based prospective observational study, using Australian Paediatric Surveillance Unit (APSU) data. Australian paediatricians and child health workers, January 2006 - July 2007. Children aged ≤ 15 years with vitamin D deficiency rickets (25-hydroxyvitamin D [25OHD] ≤ 50 nmol/L, and elevated alkaline phosphatase levels [> 229 IU/L] and/or radiological rickets). Incidence of vitamin D deficiency rickets. Description of demographics, clinical presentation, identification and further analysis of overrepresented groups, and treatment regimens compared with best-practice guidelines. We identified 398 children with vitamin D deficiency (55% male; median age, 6.3 years [range, 0.2-15 years]). The overall incidence in children ≤ 15 years of age in Australia was 4.9/100 000/year. All had a low 25OHD level (median, 28 nmol/L [range, 5-50 nmol]) and an elevated alkaline phosphatase level (median, 407 IU/L [range, 229-5443 IU/L]), and 48 (12%) were hypocalcaemic. Ninety-five children had wrist x-rays, of whom 67 (71%) had rachitic changes. Most (98%) had dark or intermediate skin colour and 18% of girls were partially or completely veiled. Most children were born in Africa (252; 63%) and 75% of children were refugees. Duration of exclusive breastfeeding was inversely related to serum vitamin D levels in children children before diagnosis. Vitamin D deficiency rickets is a significant problem in Australia among known high-risk groups. Public health campaigns to prevent, identify and tre@vitamin D deficiency, especially in high-risk groups, are essential.

  1. ACQUIRING SCOPE: A LONGITUDINAL STUDY

    2008-06-01

    Full Text Available Based on the spontaneous data of a Chinese-speaking child collected from 1 year old up to 4+ years old, this study focuses on the development of his scope by examining the scope interaction between negation and quantified NPs that occur in preverbal positions. It is found that the child is sensitive to scope at 3;2, an age much earlier than the age reported in other studies (e.g., age of 6 in Lee 1991. Further evidence shows that the child has mastered scope of negation and scope in general at the age of 4. First, starting from age 4;3, the child has managed to mark universal quantifiers and wh-phrases as well as duration phrases occurring in the preverbal position with scope markers such as dou ‘all’ and you ‘have’. Second, by the age of 4;5, the child has placed duration phrases in target positions in relation to negation.

    The prevalence of childhood overweight and obesity increased during the 1980s to the late 1990s. The prevalence of obesity is higher in socially and economically disadvantaged communities in most Westernised countries. The purpose of this study was to examine how the socioeconomic gradient in weight status, namely thinness, overweight and obesity, changes over time in a longitudinal cohort of Australian schoolchildren, from 2007-2012. 939 Australian children in school grades 2-6 from 10 primary schools initially participated in the study in 2007. Height and weight were directly measured by research assistants each year. Obesity/overweight and thinness were defined by using the International Obesity Task Force BMI cut-offs. Chi-square analyses were used to test associations between categorical variables and linear mixed models were used to estimate whether the differences in SES groups were statistically significant over time. Results found both males and females in the low SES group were more likely to be obese (6-7%) than middle (4-5%) and high (2-3%) SES groups and this pattern tended to be similar over the 6 year study period. There appeared to be no particular SES pattern for thinness with all SES groups having 4-5% of participants who were thin. The gender and SES patterns were also similar over 6 years for BMI with low and middle SES participants having significantly greater BMI than their high SES peers. Patterns of obesity and overweight in children from socially and economically disadvantaged communities in regional NSW are identifiable from a young age and the socioeconomic pattern persists into adolescence. Obesity prevention and intervention programs should be designed, implemented and evaluated with the social determinants of health in mind and in collaboration with community members. Community programs should continue to be based on positive rather than negative messages in order to avoid unintended stigma and other potentially harmful outcomes.

  4. LEADERSHIP STYLES: A STUDY OF AUSTRALIAN AND THAI PUBLIC SECTORS

    2012-01-01

    Full Text Available Leadership is deeply attached to culture. This study compares leadership styles in Thai and Australian public sectors. The data were collected from staff in public sector settings in Australia and Thailand. The results confirm four leadership styles that suit the public sector culture in both countries: communication-oriented, strategic thinking and planning, relationship building, and conflict management. In the Thai public sector system, leadership that focuses on goal orientation is ranked most highly: Australian public sector organisations focus on leadership that fosters equity among organisational members, creates a supportive environment in the workplace, and facilitates participation. It is evident from this study that significant distinctions between the organisational cultures of Thailand and Australia are matched by marked dissimilarities of preferred leadership styles. Thus, an understanding of local organisational culture is important for effective leadership at all levels.

  5. Exploring Australian Aboriginal women's experiences of menopause: a descriptive study.

    2014-03-20

    Despite extensive literature demonstrating differing experiences in menopause around the world, documentation of the experience of menopause in Australian Aboriginal women is scarce, and thus their menopausal experience is relatively unknown. This study aimed to understand Australian Aboriginal women's understanding and experience of menopause and its impact on their lives. The study was an exploratory qualitative study. Twenty-five Aboriginal women were recruited from a regional centre in the Mid-West region of Western Australia using opportunistic and snowballing sampling. Interviews and focus group discussions were undertaken from February 2011 to February 2012 using open-ended questioning with a yarning technique. Thematic analysis was undertaken of the transcribed interviews. A number of themes were revealed. These related to the language used, meanings and attitudes to menopause, symptoms experienced, the role of men, a lack of understanding, coping mechanisms and the attribution of menopausal changes to something else. The term "change of life" was more widely recognised and signified the process of ageing, and an associated gain of respect in the local community. A fear of menopausal symptoms or uncertainty about their origin was also common. Overall, many women reported insufficient understanding and a lack of available information to assist them and their family to understand the transition. There are similarities between Aboriginal and non-Aboriginal experiences of menopause, including similar symptom profiles. The current language used within mainstream health settings may not be appropriate to this population if it fails to recognise the importance of language and reflect the attributed meaning of menopause. The fear of symptoms and uncertainty of their relationship to menopause demonstrated a need for more information which has not adequately been supplied to Australian Aboriginal women through current services. While this study is with a select

  7. Longitudinal nasopharyngeal carriage and antibiotic resistance of respiratory bacteria in indigenous Australian and Alaska native children with bronchiectasis.

    Directory of Open Access Journals (Sweden)

    Kim M Hare

    Full Text Available BACKGROUND: Indigenous children in Australia and Alaska have very high rates of chronic suppurative lung disease (CSLD/bronchiectasis. Antibiotics, including frequent or long-term azithromycin in Australia and short-term beta-lactam therapy in both countries, are often prescribed to treat these patients. In the Bronchiectasis Observational Study we examined over several years the nasopharyngeal carriage and antibiotic resistance of respiratory bacteria in these two PCV7-vaccinated populations. METHODS: Indigenous children aged 0.5-8.9 years with CSLD/bronchiectasis from remote Australia (n = 79 and Alaska (n = 41 were enrolled in a prospective cohort study during 2004-8. At scheduled study visits until 2010 antibiotic use in the preceding 2-weeks was recorded and nasopharyngeal swabs collected for culture and antimicrobial susceptibility testing. Analysis of respiratory bacterial carriage and antibiotic resistance was by baseline and final swabs, and total swabs by year. RESULTS: Streptococcus pneumoniae carriage changed little over time. In contrast, carriage of Haemophilus influenzae declined and Staphylococcus aureus increased (from 0% in 2005-6 to 23% in 2010 in Alaskan children; these changes were associated with increasing age. Moraxella catarrhalis carriage declined significantly in Australian, but not Alaskan, children (from 64% in 2004-6 to 11% in 2010. While beta-lactam antibiotic use was similar in the two cohorts, Australian children received more azithromycin. Macrolide resistance was significantly higher in Australian compared to Alaskan children, while H. influenzae beta-lactam resistance was higher in Alaskan children. Azithromycin use coincided significantly with reduced carriage of S. pneumoniae, H. influenzae and M. catarrhalis, but increased carriage of S. aureus and macrolide-resistant strains of S. pneumoniae and S. aureus (proportion of carriers and all swabs, in a 'cumulative dose-response' relationship

    RESEARCH SIGNIFICANCE: Job insecurity, the subjective individual anticipation of involuntary job loss, negatively affects employees' health and their engagement. Although the relationship between job insecurity and health has been extensively studied, job insecurity as an 'exposure' has received far less attention, with little known about the upstream determinants of job insecurity in particular. This research sought to identify the relationship between self-rated job insecurity and area-level unemployment using a longitudinal, nationally representative study of Australian households. Mixed-effect multi-level regression models were used to assess the relationship between area-based unemployment rates and self-reported job insecurity using data from a longitudinal, nationally representative survey running since 2001. Interaction terms were included to test the hypotheses that the relationship between area-level unemployment and job insecurity differed between occupational skill-level groups and by employment arrangement. Marginal effects were computed to visually depict differences in job insecurity across areas with different levels of unemployment. Results indicated that areas with the lowest unemployment rates had significantly lower job insecurity (predicted value 2.74; 95% confidence interval (CI) 2.71-2.78, P unemployment (predicted value 2.81; 95% CI 2.79-2.84, P unemployment and job insecurity among precariously and fixed-term employed workers than permanent workers. These findings demonstrate the independent influences of prevailing economic conditions, individual- and job-level factors on job insecurity. Persons working on a casual basis or on a fixed-term contract in areas with higher levels of unemployment are more susceptible to feelings of job insecurity than those working permanently.

    Full Text Available Objective: The relationship between Osteoarthritis (OA and Osteoporosis (OP is not well defined due to lacking in longitudinal data, mainly regarding correlations between biochemical factors and OA incidence. Aim of this paper was to investigate the predictive value for OA incidence of bone mass variations and of selected biochemical markers in healthy women participating in a population-based longitudinal study carried out in Naples (Italy. Subjects and Methods: High completion rate (85.2% and statistically adequate sample size were obtained: 139 women (45 to 79 years of age were examined and follow up visit was performed after two years (24±2 months, following the same protocol. Patients underwent medical examination, questionnaire, anthropometric measurements, blood sampling and urine collection. Bone mineral density (BMD measurement was performed by dual energy X-ray absorptiometry (DEXA at the lumbar spine (L1-L4 and femoral neck. Radiographs of dorsal and lumbar spine in lateral view were performed at basal and at 24 months visits; a team of three experts scored radiographs using Kellegren and Lawrence grading. Results: The score was calculated for two individual radiographic features (narrowing of the joint space, presence of osteophytes and as a global score. Results show a relevant percentage, 23% up, of subjects presenting both OA and OP. In the cross-sectional study the presence of osteophytosis correlates with anthropometric variables and PTH levels. In the longitudinal study results show a correlation between serum vitamin D and delta score for osteophytosis (β=0.02 p<0.05. Conclusions: Data obtained outline the importance of further studies on the pathogenetic link between OA and bone metabolism.

    Zheng, Miaobing; Sui, Zhixian; Li, Zhangrong; Rangan, Anna

    The aim of this study was to investigate the cross-sectional associations among sugar-sweetened beverage (SSB) consumption, its substitution with beverage alternatives, and obesity outcomes in an Australian population. We used data from 9341 adults ages ≥19 y from the 2011-2012 Australian National Nutrition and Physical Activity Survey. Multivariate linear regression with adjustment for covariates was used to examine the associations between SSB consumption and body mass index (BMI) and waist circumference (WC). Substitution modeling was used to simulate the effect of replacing SSB with water, coffee/tea, fruit juice, and milk. SSB intake (100 g/d) was associated with higher BMI (β = 0.06 kg/m 2 ; P = 0.001) and WC (β = 0.19 cm; P Replacing SSB with water, coffee/tea, or milk was inversely associated with BMI (β = -0.07 to -0.09 kg/m 2 ; P < 0.001) and WC (β = -0.25 to -0.28 cm; P < 0.001). The results of the present study suggested that SSB intake is associated with obesity and that coffee/tea, water, and milk may be good alternatives for SSB. Further longitudinal and intervention studies are warranted to examine the effects of beverage substitution on obesity. Copyright © 2017 Elsevier Inc. All rights reserved.

    Parents use active and restrictive mediation strategies to guide and regulate children's online participation and the online risks they encounter. However, changes in parental mediation do occur over time and the effectiveness of these strategies on cyberbullying demands for further empirical investigation. The current study addresses these issues with a sample of 1084 students (49% girls) in a longitudinal, three-wave design. Gender differences were tested via multi-group analyses. Longitudinal growth models showed that parental use of both active and restrictive mediation decreased over time. For both types of mediation, the mean rate of change had a significant effect on boys' engagement in cyberbullying, but not for girls. Initial levels of restrictive mediation, but not active mediation, were found to be significantly predictive of cyberbullying in both genders. Girls had higher initial levels of both parental mediation types in comparison to boys. The results reveal that the effectiveness of active and restrictive mediation in relation to students' cyberbullying differs and informs us on gender differences. The implications of these results for parental education in online mediation are discussed.

    Objective: To compare two levels of stress (solitary confinement (SC) and non-SC) among remand prisoners as to incidence of psychiatric disorders in relation to prevalent disorders. Method: Longitudinal repeated assessments were carried out from the start and during the remand phase of imprisonment....... Both interview-based and self-reported measures were applied to 133 remand prisoners in SC and 95 remand prisoners in non-SC randomly selected in a parallel study design. Results: Incidence of psychiatric disorders developed in the prison was significantly higher in SC prisoners (28%) than in non......-SC prisoners (15%). Most disorders were adjustment disorders, with depressive disorders coming next. Incident psychotic disorders were rare. The difference regarding incidence was primarily explained by level of stress (i.e. prison form) rather than confounding factors. Quantitative measures of psychopathology...

    2008-07-01

    This study aimed to identify the current workload of clinical nurses, managers and educators in Australian Emergency Departments according to the classification of the department Additionally the relationship of experienced to inexperienced clinical staff was examined. A descriptive research method utilising a survey distributed to 394 Australian Emergency departments with a 21% response rate. Nursing workloads were calculated and a ratio of nurse to patient was established. The ratios included nurse to patient, management and educators to clinical staff. Additionally the percentage of junior to senior clinical staff was also calculated. Across all categories of emergency departments the mean nurse:patient ratios were 1:15 (am shift), 1:7 (pm shift) and 1:4 (night shift). During this period an average of 17.1% of attendances were admitted to hospital. There were 27 staff members for each manager and 23.3 clinical staff for each educator. The percentage of junior staff rostered ranged from 10% to 38%. Emergency nurses cannot work under such pressure as it may compromise the care given to patients and consequently have a negative effect on the nurse personally. However, emergency nurses are dynamically adjusting to the workload. Such conditions as described in this study could give rise to burnout and attrition of experienced emergency nurses as they cannot resolve the conflict between workload and providing quality nursing care.

    Few longitudinal population-based cohort studies of older people have described dietary intakes over time. The objective of this study was to assess changes in the food and nutrient intake in a cohort of older Australians, using longitudinal data collected over 10 years. Population-based cohort of people aged 49 years and over at baseline (82% of those eligible) living in two postcode areas, west of Sydney. In 1992-1994, 3654 people were examined; 2334 were reexamined after 5 years and 1952 after 10 years (75% survivors at both examinations). A 145-item food frequency questionnaire was used to assess food and nutrient intake on each occasion, and 1166 participants provided usable dietary data at all three examinations. Energy and sugar intake significantly increased among women over the 10-year period (P-value for trend bread consumption decreased in both men and women (P-value for trend choices. This information could be used to inform nutrition policy and programs targeted to older persons. These data highlight the need to identify barriers to better food choices.

    A growing body of literature highlights that racial discrimination has negative impacts on child health, although most studies have been limited to an examination of direct forms of racism using cross-sectional data. We aim to provide further insights on the impact of early exposure to racism on child health using longitudinal data among Indigenous children in Australia and multiple indicators of racial discrimination. We used data on 1239 Indigenous children aged 5-10 years from Waves 1-6 (2008-2013) of Footprints in Time, a longitudinal study of Indigenous children across Australia. We examined associations between three dimensions of carer-reported racial discrimination (measuring the direct experiences of children and vicarious exposure by their primary carer and family) and a range of physical and mental health outcomes. Analysis was conducted using multivariate logistic regression within a multilevel framework. Two-fifths (40%) of primary carers, 45% of families and 14% of Indigenous children aged 5-10 years were reported to have experienced racial discrimination at some point in time, with 28-40% of these experiencing it persistently (reported at multiple time points). Primary carer and child experiences of racial discrimination were each associated with poor child mental health status (high risk of clinically significant emotional or behavioural difficulties), sleep difficulties, obesity and asthma, but not with child general health or injury. Children exposed to persistent vicarious racial discrimination were more likely to have sleep difficulties and asthma in multivariate models than those with a time-limited exposure. The findings indicate that direct and persistent vicarious racial discrimination are detrimental to the physical and mental health of Indigenous children in Australia, and suggest that prolonged and more frequent exposure to racial discrimination that starts in the early lifecourse can impact on multiple domains of health in later life

    There is unequal access to health care in Australia, particularly for the one-third of the population living in remote and rural areas. Video consultations delivered via the Internet present an opportunity to provide medical services to those who are underserviced, but this is not currently routine practice in Australia. There are advantages and shortcomings to using video consultations for diagnosis, and general practitioners (GPs) have varying opinions regarding their efficacy. The aim of this Internet-based study was to explore the attitudes of Australian GPs toward video consultation by using a range of patient scenarios presenting different clinical problems. Overall, 102 GPs were invited to view 6 video vignettes featuring patients presenting with acute and chronic illnesses. For each vignette, they were asked to offer a differential diagnosis and to complete a survey based on the theory of planned behavior documenting their views on the value of a video consultation. A total of 47 GPs participated in the study. The participants were younger than Australian GPs based on national data, and more likely to be working in a larger practice. Most participants (72%-100%) agreed on the differential diagnosis in all video scenarios. Approximately one-third of the study participants were positive about video consultations, one-third were ambivalent, and one-third were against them. In all, 91% opposed conducting a video consultation for the patient with symptoms of an acute myocardial infarction. Inability to examine the patient was most frequently cited as the reason for not conducting a video consultation. Australian GPs who were favorably inclined toward video consultations were more likely to work in larger practices, and were more established GPs, especially in rural areas. The survey results also suggest that the deployment of video technology will need to focus on follow-up consultations. Patients with minor self-limiting illnesses and those with medical

    A longitudinal morphometric MRI study of Alzheimer's disease (AD) was conducted to determine the relationship between the progression of the symptoms and the progression of the brain atrophy. The Voxel-based Specific Regional Analysis System for Alzheimer's Disease (VSRAD), developed by Matsuda et al. was used as a method of morphometry to perform the statistical MR image analysis. Thirty-eight patients of AD patients were investigated with VSRAD. These patients were divided into two groups according to the progression of symptoms based on a clinical evaluation. One group was the progress group (20 patients), while the other group was the stable group (18 patients) for comparison. The relationship was investigated between the speed of the symptomatic progression and the change in each VSRAD indicator. Consequently, the entorhinal Z-score and the entorhinal atrophy rate showed a correlation with the speed of the symptomatic progression. The increase of the entorhinal Z-score in the follow-up was larger in the progress group than that in the stable group (0.65/1.28 years in the progress group and 0.05/1.26 years in the stable group.). These results suggest that a rapid symptomatic progression in an AD patient accompanies the rapid progression of atrophy in the entorhinal cortex. (author)

    Postpartum maternal separation anxiety refers to a mothers' experience of worry and concern about leaving her child for short-term separations. The long-term effects of high maternal separation anxiety on maternal parenting behaviors and child outcomes have been not been established empirically. The aim of this study was to ascertain the prospective relationships between maternal separation anxiety during the child's first year of life, and overprotective parenting and children's social and emotional functioning at age 2-3 years. Structural equation modeling with a large representative cohort of Australian mother-child dyads (N = 3,103) indicated that high maternal separation anxiety was associated with more overprotective parenting behaviors and poorer child socioemotional functioning at age 2-3 years. Findings suggest women with high postpartum maternal separation anxiety may sustain this vigilance across the first years following birth, promoting overprotective behaviors, and resulting in increased behavior problems in their children. Support for women around negotiating separation from their children early in parenthood may prevent the establishment of a repertoire of parenting behaviors that includes unnecessarily high vigilance, monitoring, and anxiety about separation. © 2013 American Psychological Association

    2013-10-01

    Developmental scientists have argued that the implementation of longitudinal methods is necessary for obtaining an accurate picture of the nature and sources of developmental change (Magnusson & Cairns, 1996; Morrison & Ornstein, 1996; Magnusson & Stattin, 2006). Developmentalists studying cognition have been relatively slow to embrace longitudinal research, and thus few exemplar studies have tracked individual children's cognitive performance over time and even fewer have examined contexts that are associated with this growth. In this article we first outline some of the benefits of implementing longitudinal designs. Using illustrations from existing studies of children's basic cognitive development and of their school-based academic performance, we discuss when it may be appropriate to employ longitudinal (versus other) methods. We then outline methods for integrating longitudinal data into one's research portfolio, contrasting the leveraging of existing longitudinal data sets with the launching of new longitudinal studies in order to address specific questions concerning cognitive development. Finally, for those who are interested in conducting longitudinal investigations of their own, we provide practical on-the-ground guidelines for designing and carrying out such studies of cognitive development.

    Environmental factors such as serious trauma or abuse and related stress can lead to nightmares or night terrors. Being bullied can be very distressing for children, and victims display long-term social, psychological, and health consequences. Unknown is whether being bullied by peers may increase the risk for experiencing parasomnias such as nightmares, night terrors, or sleepwalking. A total of 6796 children of the Avon Longitudinal Study of Parents and Children (ALSPAC) birth cohort were interviewed at elementary school age (8 and 10 years) about bullying experiences with a previously validated bullying interview and at secondary school age (12.9 years) about parasomnias such as nightmares, night terrors and sleepwalking by trained postgraduate psychologists. Even after adjusting for pre-existing factors related to bullying and parasomnias, being bullied predicted having nightmares (8 years odds ratio [OR], 1.23; 95% confidence interval [CI], 1.05-1.44; 10 years OR, 1.62; 95% CI, 1.35-1.94) or night terrors (8 years OR, 1.39; 95% CI, 1.10-1.75; 10 years OR, 1.53; 95% CI, 1.18-1.98) at age 12 to 13 years. Especially being a chronic victim was associated with both nightmares (OR, 1.82; 95% CI, 1.46-2.27) and night terrors (OR, 2.01; 95% CI, 1.48-2.74). Being a bully/victim also increased the risk for any parasomnia at ages 8 or 10 years (8 years OR, 1.42; 95% CI, 1.08-1.88; 10 years OR, 1.75; 95% CI, 1.30-2.36). In contrast, bullies had no increased risk for any parasomnias. Being bullied increases the risk for having parasomnias. Hence, parents, teachers, school counselors, and clinicians may consider asking about bullying experiences if a child is having parasomnias. Copyright © 2014 by the American Academy of Pediatrics.

    2014-12-01

    Full Text Available Despite a significant increase in enrolments of postgraduate international Muslim students within Australian universities, little is known about their perceptions of life within Australian homes while undertaking their studies. The aim of this study is to investigate the ways in which students’ cultural and religious traditions affect their use of domestic spaces within the homes in which they reside. The research found that participants faced some minor difficulties in achieving privacy, maintaining modesty and extending hospitality while able to perform their daily activities in Australian designed homes. The findings suggest that greater research attention needs to be given to the development of Australian home designs that are adaptable to the needs of a multicultural society. Australian society encompasses diverse cultural customs and requirements with respect to home design, and these are yet to be explored.

    2012-02-01

    In 2011 the field of video game violence experienced serious reversals with repudiations of the current research by the US Supreme Court and the Australian Government as non-compelling and fundamentally flawed. Scholars too have been calling for higher quality research on this issue. The current study seeks to answer this call by providing longitudinal data on youth aggression and dating violence as potential consequences of violent video game exposure using well-validated clinical outcome measures and controlling for other relevant predictors of youth aggression. A sample of 165, mainly Hispanic youth, were tested at 3 intervals, an initial interview, and 1-year and 3-year intervals. Results indicated that exposure to video game violence was not related to any of the negative outcomes. Depression, antisocial personality traits, exposure to family violence and peer influences were the best predictors of aggression-related outcomes. The current study supports a growing body of evidence pointing away from video game violence use as a predictor of youth aggression. Public policy efforts, including funding, would best be served by redirecting them toward other prevention programs for youth violence. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Full text:Background: Phase 1 of the Australian Imaging, Biomarkers and Lifestyle (AIBL) Flagship Study of Ageing, a three-year prospective longitudinal study recruiting 1,112 volunteers from a cross-section of Australia's elderly population, concluded with more than a quarter of the participants undergoing PiB-PET. Methods: 287 participants received PiB PET scans: 177 Healthy controls (HC); 57 Mild Cognitive Impairment (MCI) subjects; and 53 mild Alzheimer's disease (AD) patients. HC were further classified according to their subjective memory complaints and genetic predisposition. All participants underwent a comprehensive neuropsychological examination, a 3D T1 MP-RAGE and T2 FSE MR, and a PiB-PET scan. Regional and global cortical SUVR were calculated using the cerebellar cortex as reference region. A SUVR cut-off of 1.40 was used to define PiB scans as normal or abnormal. Results: Cortical PIB binding was markedly elevated in all AD patients except one. MCI subjects presented either an AD-like (63%) or normal pattern. Cortical PiB retention was abnormal in 34% of HC and the prevalence increased with age. HC with subjective memory complaints carrying an ApoE4 allele had significantly higher A burdens than non ApoE4 carriers. Conclusions: Phase 1 of the AIBL study has set the foundations for the longitudinal assessment of A burden in HC, MCI and AD. This wil assist the development of techniques for early detection of AD providing a cohort suitable for targeted early intervention studies.

    Family food choice is complex with a number of people within the family sharing food choice and preparation responsibilities. Differences in dietary behaviours also exist between various ethnic groups worldwide, and are apparent within multicultural nations such as Australia. This study examined the intergenerational transmission of eating behaviour through semi-structured family interviews with 27 three generation families (Anglo-Australian: n = 11, Chinese-Australian: n = 8, Italian-Australian: n = 8; N = 114). The influence of generation (grandparent, parent, child), role (grandmother, grandfather, mother, father, daughter, son), and ethnic background were considered. Thematic analysis identified that regardless of ethnic background, grandmothers and mothers dominated family food choice decisions even in families where fathers were primarily responsible for the preparation of family meals. The women in each generation influenced fruit and vegetable intake by controlling purchasing decisions (e.g., by shopping for food or editing family grocery shopping lists), insisting on consumption, monitoring and reminding, utilizing food as a prerequisite for conditional treats (e.g., eating fruit before being allowed snacks), instigating and enforcing food rules (e.g., fast food only on weekends), and restricting others' food choices. Grandparents and children shared a relationship that skipped the parent generation and influenced dietary behaviours bi-directionally. These findings have implications for the delivery of dietary health messages used in disease prevention interventions designed to successfully reach culturally and linguistically diverse populations and all members of multigenerational families.

    Many large scale longitudinal cohort studies have been carried out or are ongoing in different fields of science. Such studies need a careful planning to obtain the desired quality of results with the available resources. In the past, a number of researches have been performed on optimal designs for longitudinal studies. However, there was no computer program yet available to help researchers to plan their longitudinal cohort design in an optimal way. A new interactive computer program for the optimization of designs of longitudinal cohort studies is therefore presented. The computer program helps users to identify the optimal cohort design with an optimal number of repeated measurements per subject and an optimal allocations of time points within a given study period. Further, users can compute the loss in relative efficiencies of any other alternative design compared to the optimal one. The computer program is described and illustrated using a practical example.

    This paper examined whether recall of childhood trauma was associated with adult alcohol consumption in a sample of Australians with low housing security. The secondary aim was to examine whether risky alcohol consumption predicted subsequent housing instability. Sociodemographic factors were examined as potential moderators of these associations. This paper utilised data collected through the Journeys Home Study, a longitudinal study of a representative sample of individuals who were homeless or at risk of homelessness. This paper focused on 1224 participants aged 18 years and over. Data on alcohol use, childhood trauma and sociodemographic characteristics were collected through interviews at baseline. Homeless status at 6- to 12-month follow-up was assessed via interview. Logistic regression modelling was used to examine associations of alcohol consumption with childhood abuse, sociodemographic factors and changes in homelessness status. Self-reported recall of childhood experiences of violence was more likely among current drinkers, risky or not, than among abstainers. Recall of childhood neglect was more common among abstainers than among risky drinkers. The relationships between recall of childhood trauma and adult alcohol consumption are likely to be complex. Risky consumption may contribute to continuing homelessness among adults with unstable housing.

    to report findings on midwives' use of the Internet drawn from a larger study that explored midwives' attitudes and experiences to online and computer-based learning. a descriptive, quantitative design using anonymous questionnaires was employed to obtain information from a sample of midwives in Victoria, Australia. questionnaires were forwarded by mail to a sample of 300 members of the Victorian branch of the Australian College of Midwives. A total of 169 questionnaires were returned by reply paid mail, representing a response rate of 56%. around 92.3% of respondents reported that they used the Internet. However, 31.5% did not find navigating it to be easy, 34.7% reported that finding information was not easy, and 27.2% were not confident using the Internet. many midwives have insufficient Internet competence to be able to access necessary evidence to support practice and to assist women with decision making. ongoing education and training is needed to ensure that midwives have the skills to source evidence to support practice, and are able to effectively critique Internet information.

    To explore the associations between serum 25-hydroxyvitamin D (25D) and 1,25-dihydroxyvitamin D (1,25D) levels at baseline and incidence of sarcopenia over time in older Australian community-dwelling older men. Of the 1,705 men aged ≥70 years (2005-2007) participating in the Concord Health and Ageing in Men Project, those without sarcopenia at baseline (n = 1,312 for 25D and n = 1,231 for 1,25D), 2 years (n = 1,024 for 25D and n = 956 for 1,25D), and 5-year follow-up (n = 709 for 25D and n = 663 for 1,25D) were included in the study. The main outcome measurement was the incidence of sarcopenia defined as appendicular lean mass adjusted for body mass index sarcopenia was 3.9% in men at the 2-year follow-up and 8.6% at the 5-year follow-up. In adjusted analysis, men with vitamin D levels in the lowest quartiles (25D sarcopenia compared to those with vitamin D levels in the highest quartiles over 5 years. [25D: odds ratio (OR) 2.53 (95% confidence interval (CI) 1.14, 5.64) p = .02; 1,25D: OR 2.67 (95% CI 1.28, 5.60) p = .01]. After further adjustments for the respective other serum vitamin D measure, (either 25D or 1,25D), the association remained significant [25D: OR 2.40 (95% CI 1.02, 5.64) p = .04; 1,25D: OR 2.23 (95% CI 1.04, 4.80) p = .04]. Low serum 1,25D and 25D concentrations at baseline are independently associated with the incidence of sarcopenia over the subsequent 5 years. Although our data do not prove any causal relationship, it is conceivable that maintaining vitamin D sufficiency may reduce the incidence of sarcopenia in ageing men. © Crown copyright 2017

    The purpose of this work was to determine relationships between BMI status at ages 4 to 5 years and mothers' and fathers' parenting dimensions and parenting styles. Participants were composed of all 4983 of the 4- to 5-year-old children in wave 1 of the nationally representative Longitudinal Study of Australian Children with complete BMI and maternal parenting data. Mothers and fathers self-reported their parenting behaviors on 3 multi-item continuous scales (warmth, control, and irritability) and were each categorized as having 1 of 4 parenting styles (authoritative, authoritarian, permissive, and disengaged) using internal warmth and control tertile cut points. Using a proportional odds model, odds ratios for children being in a higher BMI category were computed for mothers and fathers separately and together, after adjustment for factors associated with child BMI, including mothers' and fathers' BMI status. The sample was composed of 2537 boys and 2446 girls with a mean age 56.9 months; 15% were overweight and 5% were obese (International Obesity Task Force criteria). Mothers' parenting behaviors and styles were not associated in any model with higher odds of children being in a heavier BMI category, with or without multiple imputation to account for missing maternal BMI data. Higher father control scores were associated with lower odds of the child being in a higher BMI category. Compared with the reference authoritative style, children of fathers with permissive and disengaged parenting styles had higher odds of being in a higher BMI category. This article is the first, to our knowledge, to examine the parenting of both parents in relation to preschoolers' BMI status while also adjusting for parental BMI status. Fathers' but not mothers' parenting behaviors and styles were associated with increased risks of preschooler overweight and obesity. Longitudinal impacts of parenting on BMI gain remain to be determined.

    Rupture of the anterior cruciate ligament (ACL) is a common and debilitating injury that impacts significantly on knee function and risks the development of degenerative arthritis. The outcome of ACL surgery is not monitored in Australia. The optimal treatment is unknown. Consequently, the identification of best practice in treating ACL is crucial to the development of improved outcomes. The Australian Knee Society (AKS) asked the Australian Orthopaedic Association (AOA) to consider establishing a national ACL registry. As a first step, a pilot study was undertaken by the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) to test the hypothesis that collecting the required information in the Australian setting was possible. Surgeons completed an operative form which provided comprehensive information on the surgery undertaken. Patients provided pre- and post-operative questionnaires including the Knee Injury and Osteoarthritis Outcome Score (KOOS) and the Marx Activity Scale (MA Scale). The number of ACL procedures undertaken at each hospital during the recruitment period was compared against State Government Health Department separation data. A total of 802 patients were recruited from October 2011 to January 2013. The overall capture rate for surgeon-derived data was 99%, and the capture rate for the pre-operative patient questionnaire was 97.9%. At 6 months, patient-reported outcomes were obtained from 55% of patients, and 58.5% of patients at 12 months. When checked against State Government Health Department separation data, 31.3% of procedures undertaken at each study hospital were captured in the study. It is possible to collect surgeon-derived and pre-operative patient-reported data, following ACL reconstruction in Australia. The need to gain patient consent was a limiting factor to participation. When patients did consent to participate in the study, we were able to capture nearly 100% of surgical procedures. Patient consent

    The aim of this study was to investigate and compare symptom experiences, beliefs, attitudes, and understanding of menopause and menopausal therapies in Australian and Laotian women. This was a cross-cultural, questionnaire-based study involving 108 women (56 Australian women and 52 Laotian women aged 40-65 y) attending outpatient clinics in Australia and Laos. Descriptive statistics and univariate analysis were conducted using Student's t test or Mann-Whitney U test, where appropriate. Psychological symptoms, depression, vasomotor symptoms, and sexual dysfunction were significantly higher in Australian women compared with Laotian women (P menopause as aging (57%), whereas most Laotian women reported not knowing what menopause meant to them (81%). Australian women's fears about menopause included weight gain (43%), aging (41%), and breast cancer (38%), whereas Laotian women reported not knowing about potential menopausal problems (85%). Exercise (55%), education and awareness (46%), and improving lifestyle (41%) were reported by Australian women as being effective in alleviating menopausal symptoms, with only 21% reporting not knowing what was effective compared with 83% of Laotian women. Many women reported not knowing the risks/benefits of hormonal therapies (50% of Australian women and 87% of Laotian women) and herbal therapies (79% of Australian women and 92% of Laotian women). General practitioners were the most common source of menopause information for both Australians (73%) and Laotians (67%). Sociocultural factors influence women's perception of menopause. Psychological symptoms, sexual dysfunction, and vasomotor symptoms are more commonly reported by Australian women than by Laotian women. Women have a limited understanding of the risks/benefits of menopausal therapies, and culturally appropriate education is needed.

    Unconfounded comparative data on the type and dose of immunosuppressive agents among solid organ transplant recipients are sparse, as are data on longitudinal immunosuppressive therapy since transplantation. We addressed this issue in a population-based cohort of Australian liver (n = 1895), heart (n = 1220), and lung (n = 1059) transplant recipients, 1984-2006. Data on immunosuppressive therapy were retrospectively collected at discharge, three months, and one, five, 10, and 15 yr after first transplant. We computed unadjusted and adjusted estimates for the association between the type and dose of immunosuppressive therapy and organ type. After adjustment for confounders, use of induction antibody and maintenance corticosteroids was more common in heart and lung compared to liver recipients (p heart and lung recipients (p heart and lung recipients (p transplanted organ, for example, malignancy risk. Longitudinal changes in the type and the dose of immunosuppressive therapy over time since transplantation also demonstrate the need for time-dependent data in observational research. © 2015 John Wiley & Sons A/S.

    Background Behavioural and lifestyle factors associated with childhood unwanted sexual experiences (USE) have yet to be investigated in Australian females aged less than 18 years. Women aged 16-25 years living in Victoria were recruited via targeted advertising on Facebook. A web-based validated questionnaire was used to collect information on participant demographics, mental health, USE and sexual behaviours. Multivariable logistic regression was used to determine associations between a history of childhood (<16 years) and adolescent (16-18 years) USE and indices of sexual orientation. Data were collected from 639 females (mean±s.d. age 22±3 years). Approximately 14% reported childhood USE and 15% reported adolescent USE. Approximately 37% of survivors of childhood USE reported penile-genital contact in relation to their USE. Participants who reported depression were almost four times as likely to have experienced childhood USE than those who did not report suffering from depression (odds ratio 3.6, 95% confidence interval 2.1-6.0, P<0.001). Positive associations between childhood USE, same-sex relationships and smoking were also detected. A strong relationship between childhood USE, depression and same-sex sexual behaviours was found, but results did not determine the direction of this association. Longitudinal studies should be conducted to investigate whether there are groups of individuals who are at a high risk of experiencing childhood USE, so that appropriate support systems can be put in place.

    Drawing on the expectancy-value model, the present study explored individual and gender differences in university entry and selection of educational pathway (e.g., science, technology, engineering, and mathematics [STEM] course selection). In particular, we examined the multiplicative effects of expectancy and task values on educational outcomes during the transition into early adulthood. Participants were from a nationally representative longitudinal sample of 15-year-old Australian youths (N = 10,370). The results suggest that (a) both math self-concept and intrinsic value interact in predicting advanced math course selection, matriculation results, entrance into university, and STEM fields of study; (b) prior reading achievement has negative effects on advanced math course selection and STEM fields through math motivational beliefs; and (c) gender differences in educational outcomes are mediated by gender differences in motivational beliefs and prior academic achievement, while the processes underlying choice of educational pathway were similar for males and females.

    The aim of the present study was to identify the core values of Australian psychiatrists to ascertain how these are reflected in the Royal Australian and New Zealand College of Psychiatrists (RANZCP) Code of Ethics. An ethnomethodological study was conducted on a non-purposive sample of Australian psychiatrists using a non-probabilistic theoretical sampling method. Data obtained at interview were analysed using a qualitative computer-assisted thematic analysis paradigm. The themes generated using this coding strategy were refined into a rich description of the core values held by Australian psychiatrists. Four main values emerged from the data: the value of the patient, the value of sophisticated understanding, the value of reflexivity, and the value of advocacy. The four main values identified in the present study were well reflected in the main principles of the RANZCP Code of Ethics. In the light of the data, some additional annotations to the document are suggested, to better reflect this value system.

    This study was designed to obtain data on public understanding of genetic concepts in the adult population of Western Australia. It explored knowledge of genetic risk of disease, inheritance, biology, determinism, and factors that predict relatively higher genetic knowledge within the general population. A cross-sectional telephone survey of 1,009 respondents. Most members of the Western Australian community are aware of basic genetic concepts and the link between genes, inheritance, and risk of disease. Significantly fewer understand the biological mechanisms underlying these concepts and there was some misconception around the meaning of 'increased genetic risk'. The odds of higher genetic knowledge (>19 out of 24 questions correct) were greater among those with 12 years or more education (OR = 3.0), those aged 18-44 years (OR = 2.3), women (OR = 2.0), those with annual household income of AUD 80,000 or more (OR = 1.8), and those who had talked with someone (OR = 1.7) or searched the internet (OR = 1.6) for information on genes and health. This study provides evidence of an association between social location and public knowledge of human genetic concepts related to health and disease. This is consistent with previous findings and raises questions about the acquisition of textbook genetics knowledge within socio-cultural contexts. The impact of misconceptions about genetic concepts on the uptake of preventive health behaviors requires further investigation, as does the level of genetics knowledge that is required to empower informed participation in individual and societal decisions about genetics and health.

    2010-05-01

    To determine the prevalence and associations of refractive error within the indigenous Australian population living in central Australia. 1884 individuals aged 20 years or older, living in one of 30 remote communities within the statistical local area of 'central Australia' were recruited for this study. This equated to 36% of those aged 20 years or older and 67% of those aged 40 years or older within this district. Participants were recruited as they presented to the eye clinic at each remote community. Participants underwent subjective refraction to determine spherical equivalent and then had a slit-lamp anterior segment examination. Participants were only included if they were phakic and only the right eye was considered. The prevalence of hypermetropia worse than +1.0 dioptres (D), myopia worse than -0.5 D and astigmatism worse than 1.0 D is presented. From those recruited, 15.2% were hypermetropic; 11.1% were myopic; and 6.2% had astigmatism. Participants became progressively more hypermetropic with increasing age until the age of 70 years, after which time they become more myopic. Furthermore, there was an increasing likelihood of myopia and a decreasing likelihood of hypermetropia with increasing nuclear opalescent cataract. Our study has shown that indigenous Australians are less likely to be ametropic compared with non-indigenous groups. Variations with age and nuclear opalescent cataract seen in other previous work have also been observed in our sample.

    To investigate the association of hormone levels at menopause, lifestyle variables, and body composition with the predicted 10-year risk of a coronary event, calculated using the PROCAM scoring system, in a population-based sample of Australian-born, middle-aged women. A 9-year prospective study of 438 Australian-born women, who at baseline were aged 45 to 55 years and had menstruated in the prior 3 months. Interviews, fasting blood, and physical measurements were taken annually. The risk of an acute coronary event was calculated using the PROCAM scoring system (includes: age, low-density lipoprotein cholesterol, smoking, high-density lipoprotein cholesterol, systolic blood pressure, family history of premature myocardial infarction, diabetes mellitus, and triglycerides). Retention rate after 8 years of follow-up was 88% (n = 387). In women not using hormone therapy (HT): higher than average body mass index (BMI) (P < 0.001), BMI that increased (P < 0.005), lower than average estradiol levels (P < 0.005), estradiol levels that decreased (P < 0.001), and high free testosterone levels (P < 0.05) were associated with increased risk of a coronary event. There was a trend for high exercise frequency to be associated with a decreased risk (P < 0.07). After BMI and lifestyle variables were taken into account, use of HT did not have a significant effect on risk of a coronary event. In this longitudinal observational study of middle-aged Australian-born women, high BMI, an increase in BMI, high free testosterone, low estradiol, and a decrease in estradiol levels were the main determinants of increased risk of an acute coronary event, based on the PROCAM scoring system calculation. More frequent exercise tended to lower the risk.

    Romaniuk, Helena; Patton, George C; Carlin, John B

    2014-11-01

    Multiple imputation has entered mainstream practice for the analysis of incomplete data. We have used it extensively in a large Australian longitudinal cohort study, the Victorian Adolescent Health Cohort Study (1992-2008). Although we have endeavored to follow best practices, there is little published advice on this, and we have not previously examined the extent to which variations in our approach might lead to different results. Here, we examined sensitivity of analytical results to imputation decisions, investigating choice of imputation method, inclusion of auxiliary variables, omission of cases with excessive missing data, and approaches for imputing highly skewed continuous distributions that are analyzed as dichotomous variables. Overall, we found that decisions made about imputation approach had a discernible but rarely dramatic impact for some types of estimates. For model-based estimates of association, the choice of imputation method and decisions made to build the imputation model had little effect on results, whereas estimates of overall prevalence and prevalence stratified by subgroup were more sensitive to imputation method and settings. Multiple imputation by chained equations gave more plausible results than multivariate normal imputation for prevalence estimates but appeared to be more susceptible to numerical instability related to a highly skewed variable. © The Author 2014.

  12. Securitization of Migration: an Australian case study of global trends

    Directory of Open Access Journals (Sweden)

    Michael Humphrey

    2014-08-01

    Full Text Available Post September 11 migration has increasingly been framed as a security problem. In the 2010 Australian election campaign migration was connected to security (defense of our borders, terrorism and social cohesion and to related issues of insecurity about the future (population size,sustainability and economic growth. Thisframing of migration as a national security issue overlooks the reality that Australian immigration is part of the global flow of population. Migration is an international issue experienced by states as a national question of border control and sovereignty seeking to manage the consequences of global inequality and mobility. This paper analyses the 'security turn' in migration debates in Australia and the North and the way the securitization of migration signifies the transformation of security from the problem of producing national order to the problem of managing global disorder resulting in the merging of national and international security strategies.

    Cheng, Christina; Dunn, Matthew

    2015-08-01

    Almost 80% of Australian Internet users seek out health information online so the readability of this information is important. This study aimed to evaluate the readability of Australian online health information and determine if it matches the average reading level of Australians. Two hundred and fifty-one web pages with information on 12 common health conditions were identified across sectors. Readability was assessed by the Flesch-Kincaid (F-K), Simple Measure of Gobbledygook (SMOG) and Flesch Reading Ease (FRE) formulas, with grade 8 adopted as the average Australian reading level. The average reading grade measured by F-K and SMOG was 10.54 and 12.12 respectively. The mean FRE was 47.54, a 'difficult-to-read' score. Only 0.4% of web pages were written at or below grade 8 according to SMOG. Information on dementia was the most difficult to read overall, while obesity was the most difficult among government websites. The findings suggest that the readability of Australian health websites is above the average Australian levels of reading. A quantifiable guideline is needed to ensure online health information accommodates the reading needs of the general public to effectively use the Internet as an enabler of health literacy. © 2015 Public Health Association of Australia.

    This study aims to examine repeatability of reduced rank regression (RRR) methods in calculating dietary patterns (DP) and cross-sectional associations with overweight (OW)/obesity across European and Australian samples of adolescents. Data from two cross-sectional surveys in Europe (2006/2007 Healthy Lifestyle in Europe by Nutrition in Adolescence study, including 1954 adolescents, 12-17 years) and Australia (2007 National Children's Nutrition and Physical Activity Survey, including 1498 adolescents, 12-16 years) were used. Dietary intake was measured using two non-consecutive, 24-h recalls. RRR was used to identify DP using dietary energy density, fibre density and percentage of energy intake from fat as the intermediate variables. Associations between DP scores and body mass/fat were examined using multivariable linear and logistic regression as appropriate, stratified by sex. The first DP extracted (labelled 'energy dense, high fat, low fibre') explained 47 and 31 % of the response variation in Australian and European adolescents, respectively. It was similar for European and Australian adolescents and characterised by higher consumption of biscuits/cakes, chocolate/confectionery, crisps/savoury snacks, sugar-sweetened beverages, and lower consumption of yogurt, high-fibre bread, vegetables and fresh fruit. DP scores were inversely associated with BMI z-scores in Australian adolescent boys and borderline inverse in European adolescent boys (so as with %BF). Similarly, a lower likelihood for OW in boys was observed with higher DP scores in both surveys. No such relationships were observed in adolescent girls. In conclusion, the DP identified in this cross-country study was comparable for European and Australian adolescents, demonstrating robustness of the RRR method in calculating DP among populations. However, longitudinal designs are more relevant when studying diet-obesity associations, to prevent reverse causality.

    The main longitudinal limitation for LHC-type beams inthe PS are coupled-bunch instabilities. A dedicated proto-typefeedbacksystemusingaFinemetcavityasalongitudinalkicker has been installed. Extensive tests with beam havebeen performed to explore the intensity reach with this feed-back. The maximum intensity with nominal longitudinalemittance at PS extraction has been measured, as well as theemittance required to keep the beam longitudinally stableat the design intensity for the High-Luminosity LHC (HL-LHC). A higher-harmonic cavity is a complementary op-tion to extend the intensity reach beyond the capabilities ofthe coupled-bunch feedback. Preliminary machine develop-ment (MD) studies operating one20MHzor one40MHzRF system as a higher harmonic at the flat-top indicate thebeneficial effect on longitudinal beam stability

    Workers' compensation claims for older workers and workers who have suffered psychological injury are increasing as a proportion of total claims in many jurisdictions. In the Australian state of Victoria, claims from both these groups are associated with higher than average wage replacement and healthcare expenditures. This cohort profile describes a longitudinal study which aims to investigate differences in the return to work (RTW) process for older workers compared with younger workers and claimants with musculoskeletal injuries compared with those with psychological injuries. This prospective cohort study involved interviewing workers' compensation claimants at three time points. The cohort was restricted to psychological and musculoskeletal claims. Only claimants aged 18 and over were recruited, with no upper age limit. A total of 869 claimants completed the baseline interview, representing 36% of the eligible claimant population. Ninety-one per cent of participants agreed at baseline to have their survey responses linked to administrative workers' compensation data. Of the 869 claimants who participated at baseline, 632 (73%) took part in the 6-month follow-up interview, and 572 (66%) participated in the 12-month follow-up interview. Information on different aspects of the RTW process and important factors that may impact the RTW process was collected at the three survey periods. At baseline, participants and non-participants did not differ by injury type or age group, but were more likely to be female and from the healthcare and social assistance industry. The probability of non-participation at follow-up interviews showed younger age was a statistically significant predictor of non-participation. Analysis of the longitudinal cohort will identify important factors in the RTW process and explore differences across age and injury type groups. Ongoing linkage to administrative workers' compensation data will provide information on wage replacement and

    This longitudinal study of midage women has two main aims: to examine the effect of disordered eating (DE) on quality of life (QoL) among women, including a comparison with a younger cohort and to investigate the mediating roles of both depressive symptoms and social support on the longitudinal relationship between DE and QoL as potential mechanisms of action. We used self-report data from six waves of the Australian Longitudinal Study on Women's Health over 14 years. A total of 12,338 women participating in the midage cohort (aging from 45-50 to 59-64) provided self-report indications of DE at Surveys 1 and 2, and QoL (SF-36 component scales-mental [MCS] and physical [PCS]) at Surveys 2-6. DE was reported by 10.98% of the women; this group also reported significantly poorer mental and physical QoL than those without DE, and this effect was sustained over time. Comparison with a parallel analysis of a younger cohort of women showed that the effect on midage women's physical QoL is greater than that of the younger women. The relationships between baseline DE and changes in QoL (both physical and mental) over time were mediated by levels of depressive symptoms and of social support over time. This study underscores the significant effect of DE on QoL in midage, an effect which is partially or fully mediated by depressive symptoms or social support. Well-being of midage women with indicators of DE needs to be supported by tailoring prevention and interventions activities specifically for this group. (c) 2015 APA, all rights reserved).

    Rural communities throughout Australia are experiencing demographic ageing, increasing burden of chronic diseases, and de-population. Many are struggling to maintain viable health care services due to lack of infrastructure and workforce shortages. Hence, they face significant health disadvantages compared with urban regions. Primary health care yields the best health outcomes in situations characterised by limited resources. However, few rigorous longitudinal evaluations have been conducted to systematise them; assess their transferability; or assess sustainability amidst dynamic health policy environments. This paper describes the study protocol of a comprehensive longitudinal evaluation of a successful primary health care service in a small rural Australian community to assess its performance, sustainability, and responsiveness to changing community needs and health system requirements. The evaluation framework aims to examine the health service over a six-year period in terms of: (a) Structural domains (health service performance; sustainability; and quality of care); (b) Process domains (health service utilisation and satisfaction); and (c) Outcome domains (health behaviours, health outcomes and community viability). Significant international research guided the development of unambiguous reliable indicators for each domain that can be routinely and unobtrusively collected. Data are to be collected and analysed for trends from a range of sources: audits, community surveys, interviews and focus group discussions. This iterative evaluation framework and methodology aims to ensure the ongoing monitoring of service activity and health outcomes that allows researchers, providers and administrators to assess the extent to which health service objectives are met; the factors that helped or hindered achievements; what worked or did not work well and why; what aspects of the service could be improved and how; what benefits have been realised and for whom; the level of

    When information on changes in address or migration of people to or from a study jurisdiction is unavailable in longitudinal studies, issues relating to loss-to-follow-up and misclassification bias may result. This study investigated how estimations of associations between general practitioner (GP) contact and hospital use were affected by incomplete address and migration data. This was a retrospective population-based cohort study of Western Australians from 1990 to 2004. Linked administrative data including mortality records, hospital admissions, primary care and Electoral Roll records were used. Regularity of GP contact, based on the variance of the number of days between GP visits, was calculated for each person-year. Outcomes were the number and costs (A$2014) of diabetes-related hospital admissions in the following year. Models were estimated separately for cohorts where (i) postcode was ascertained at study commencement and held constant, and (ii) postcode and residency within Western Australia were updated with each change of address recorded on the Electoral Roll over the study period. Updating address data reduced total person-years by 11% and changed the distribution of covariates. Estimations of associations between patterns of GP contact and number of hospitalizations changed; the incidence rate ratios measuring the relationship with the most regular GP contact (baseline of those with <2 GP visits) changed from 0.81 [95% confidence interval (CI) 0.66-1.00] to 0.42 (95% CI 0.33-0.53) after updating postcode information. Impacts on cost models were smaller, though still statistically significant. Longitudinal studies using administrative data may report biased results if they ignore address changes and migration. Researchers should attempt to link to these data wherever possible, or choose study designs which these issues are less likely to affect. Custodians should be aware that such data can be vital to high quality research. © The Author 2017; all

    It is well established from different population-based studies that visual impairment is associated with increased mortality rate. However, to our knowledge, the association of visual impairment with increased mortality rate has not been reported among indigenous Australian individuals. To assess the association between visual impairment and 10-year mortality risk among the remote indigenous Australian population. Prospective cohort study recruiting indigenous Australian individuals from 30 remote communities located within the central Australian statistical local area over a 36-month period between July 2005 and June 2008. The data were analyzed in January 2017. Visual acuity, slitlamp biomicroscopy, and fundus examination were performed on all patients at recruitment. Visual impairment was defined as a visual acuity of less than 6/12 in the better eye. Mortality rate and mortality cause were obtained at 10 years, and statistical analyses were performed. Hazard ratios for 10-year mortality with 95% confidence intervals are presented. One thousand three hundred forty-seven patients were recruited from a total target population number of 2014. The mean (SD) age was 56 (11) years, and 62% were women. The total all-cause mortality was found to be 29.3% at 10 years. This varied from 21.1% among those without visual impairment to 48.5% among those with visual impairment. After adjustment for age, sex, and the presence of diabetes and hypertension, those with visual impairment were 40% more likely to die (hazard ratio, 1.40; 95% CI, 1.16-1.70; P = .001) during the 10-year follow-up period compared with those with normal vision. Bilateral visual impairment among remote indigenous Australian individuals was associated with 40% higher 10-year mortality risk compared with those who were not visually impaired. Resource allocation toward improving visual acuity may therefore aid in closing the gap in mortality outcomes between indigenous and nonindigenous Australian

    Background Young men can be difficult to engage in health research using traditional methods of recruitment. Social networking sites are increasingly being used to recruit participants into health research, due to their cost effectiveness, overall generalizability, and wide reach. Objective The aim of this study was to determine the feasibility of using Facebook to recruit young Australian men into a human papillomavirus (HPV) prevalence study. Methods We recruited male permanent residents of Australia, aged 18 to 35 years, into the HPV in Young Males (HYM) study through targeted advertising placed on Facebook. Consenting participants completed an online questionnaire and provided a self-collected penile swab for HPV DNA detection and genotyping. We compared sociodemographic characteristics of the study population with those of the general Australian male population, based on Australian 2011 census data. Results Between February 2015 and February 2017, targeted Facebook advertisements reached 1,523,239 men, resulting in 41,811 clicks through to the study website, with 1072 (2.56%) converting to lodgment of an expression of interest. Of these, 681 (63.53%) provided written informed consent and 535 (78.6% of recruited participants) completed all the study requirements. Reasons for participating in the study included altruism, past history of HPV, gaining more knowledge about HPV or the vaccine, working in the health industry, and the monetary compensation. The average advertising cost per completed study participant was Aus $48. Compared with the census population, HYM study participants were more likely to be Australian born (PFacebook is a feasible and efficient strategy for the recruitment of men from across Australia for HPV testing. This method could be used for monitoring the impact of HPV vaccination. Additional targeting may achieve a sample that is broadly demographically representative of the Australian population. Future research should explore how the

Heights were converted to standard deviation scores (SDSs) based on CDC and WHO. Means and standard deviations of height-SDS varied between CDC and WHO definitions and with age and gender within each definition. However, both identified similar frequencies of short stature (standard/reference for height. © 2014 The Authors.

    Considering the ethical issues related to nursing and that Ethics is an integral part of the nursing education in the degree course, one would suppose that academic dishonesty might be less frequent in nursing students than in students of other disciplines. However, several studies show that this trend of deceitful behaviour seems to be similar among the university nursing students and those of other disciplines. The aim of this study is to investigate the phenomenon of academic dishonesty in the classroom from a longitudinal perspective within a cohort of Italian nursing students. A non-experimental longitudinal design was used. All nursing students were recruited from the Nursing Science Bachelor Degree Program of a big Italian university in the centre of Italy and participants were part of an ongoing longitudinal research project which started in 2011 on nursing students' wellbeing. The results show that students get accustomed to taking academically deceitful actions. They come to consider their behaviours acceptable and normal, thereby stabilizing them, which increases the probability of stabilizing subsequent deceitful behaviours. The stability through time of academic cheating behaviours committed during higher education, within the study's timeframe, provides important perspectives into the establishment of rigorous standards of ethical and moral behaviours by the students.

    1995-01-01

    Results from longitudinal tracking studies for a high intensity proton synchrotron designed for a 1-MW spallation source are presented. The machine delivers a proton beam of 0.5 mA time-averaged current at a repetition rate of 30 Hz. The accelerator is designed to have radiation levels that allow hands-on-maintenance. However, the high beam intensity causes strong space charge fields whose effects may lead to particle loss and longitudinal instabilities. The space charge fields modify the particle distribution, distort the stable bucket area and reduce the rf linear restoring force. Tracking simulations were conducted to analyze the space charge effects on the dynamics of the injection and acceleration processes and means to circumvent them. The tracking studies led to the establishment of the injected beam parameters and rf voltage program that minimized beam loss and longitudinal instabilities. Similar studies for a 10-GeV synchrotron that uses the 2-GeV synchrotron as its injector are also discussed

    The use of online resources to reduce the attrition of program participants in longitudinal studies is examined. Higher-risk individuals, those involved in illegal activities, and females with last name changes are typically more difficult to locate. The effectiveness of using online resources for these participants is addressed. These resources include social networking sites, people-finder search engines, telephone and address directories, judicial records, and death records. The strengths and limitations of these resources are presented and discussed. Longitudinal studies using these resources are examined to evaluate their successful follow-up rates. The results of these studies indicate that participant characteristics are more important to successful follow-up than the length of time since participation or sample size. The use of multiple online sites increased follow-up rates, especially for those who are typically difficult to locate. The variables and websites to consider are discussed, and six lessons learned are offered. The prospective use of online participant involvement is especially important for successful longitudinal evaluation and program planning. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Given the high prevalence of mental health problems among prisoners, knowledge on its determinants is important. Prior cross-sectional studies suggest that procedurally just treatment within prison is a significant predictor; however, longitudinal research is lacking. The aims of this study were to examine (1) the longitudinal relationship between prisoners' perceptions of procedural justice--including fairness, respect, humanity and relationships with officers--and their mental health and (2) the moderating role of coping style in this relationship. Data were obtained from the Prison Project, a longitudinal study of adult male prisoners in the Netherlands, interviewed both 3 weeks and 3 months after their reception into pre-trial detention (N = 824). A cross-lagged structural equation model was employed to investigate associations. Prisoners who reported experiencing a higher level of procedural justice 3 weeks after their arrival in custody reported fewer mental health problems after 3 months. No evidence was found that coping style moderated this relationship. These findings suggest a causal relationship between procedural justice and psychological well-being. Fair and respectful treatment of prisoners is a predictor not only of prison order and prisoners' compliance but also of prisoners' psychological well-being. Copyright © 2013 John Wiley & Sons, Ltd.

    To identify trajectories of heroin use in Australia, predictors of trajectory group membership and subsequent outcomes among people with heroin dependence over 10-11 years. Longitudinal cohort study. Sydney, Australia. A total of 615 participants were recruited between 2001 and 2002 as part of the Australian Treatment Outcome Study (66.2% male; mean age 29 years). The predominance of the cohort (87.0%) was recruited upon entry to treatment (maintenance therapies, detoxification and residential rehabilitation), and the remainder from non-treatment settings (e.g. needle and syringe programmes). This analysis focused upon 428 participants for whom data on heroin use were available over 10-11 years following study entry. Structured interviews assessed demographics, treatment history, heroin and other drug use, overdose, criminal involvement, physical health and psychopathology. Group-based trajectory modelling was used to: (i) identify trajectory groups based on use of heroin in each year, (ii) examine predictors of group membership and (iii) examine associations between trajectory group membership and 10-11-year outcomes. Six trajectory groups were identified [Bayesian Information Criterion (BIC) = -1927.44 (n = 4708); -1901.07 (n = 428)]. One in five (22.1%) were classified as having 'no decrease' in heroin use, with the probability of using remaining high during the 10-11 years (> 0.98 probability of use in each year). One in six (16.1%) were classified as demonstrating a 'rapid decrease to maintained abstinence'. The probability of heroin use among this group declined steeply in the first 2-3 years and continued to be low (membership, but group membership was predictive of demographic, substance use and physical and mental health outcomes at 10-11 years. Long-term trajectories of heroin use in Australia appear to show considerable heterogeneity during a decade of follow-up, with few risk factors predicting group membership.

    Full Text Available OBJECTIVE: The aim of this study is to describe the evolution of multimorbidity. STUDY DESIGN AND SETTING: Data from 1854 South Australians who participated in the North West Adelaide longitudinal Health Study (NWAHS was collected between baseline (2000-2002 and follow-up (2008-2010. Status for eight chronic diseases (CDs was determined by biomedical measurement or self-report. Chronic disease (CD mean age of occurrence and order of appearance was investigated. RESULTS: The prevalence of multimorbidity increased from 32% to 64% during the 7.8±1.1 years of follow-up. The estimated mean age of onset of a new CD was significantly older for hypertension, cardiovascular disease (CVD and chronic obstructive pulmonary disease (COPD and younger for hypercholesterolemia, asthma and other mental problem. Hypercholesterolemia was more likely to develop as a first than as a subsequent CD (39%vs.16%, p<0.0001 while CVD (1%vs.5%, p<0.0001, diabetes (5%vs.11%, p<0.001 and COPD (6%vs.16%, p<0.0001 were less likely. The presence of mood disorders at baseline was associated with an increased risk of developing other mental disorders (36%vs.12%, p<0.0001, diabetes (18%vs.9%, p<0.01 and asthma (30%vs.21%, p<0.05. CONCLUSION: Longitudinal data could be used to study the evolution of multimorbidity and could provide information on CDs mean age of occurrence, order of appearance and impact on the development of future CDs.

    Carolina P.M. Pereira

    Full Text Available Abstract Cognitive changes in normal aging can be similar to the alterations that take place in the initial stages of a dementia process. Longitudinal studies can provide a better understanding of this progression. Objectives: To evaluate the cognitive and functional evolution of community-dwelling individuals without dementia through a three-year longitudinal study. Methods: 168 individuals were evaluated in 2006. Three years later in 2009, 73 of these subjects were reevaluated as regards cognition and functionality using the Mini Mental State Examination (MMSE, Brief Cognitive Battery (BCB and the Pfeffer Functional Activities Questionnaire. The statistical analysis included descriptive measurements, the Wilcoxon's test for intra-group comparison, and the Spearman's correlation coefficient test for comparing cognitive and functionality scores. Results: After three years, the Wilcoxon's test showed a discreet yet significant cognitive decline (MMSE: -0.7 points; p=0.02; Z= -2.29; and global score on the BCB: +3.6 points; p=0.02; Z= -2.29, in addition to functional decline (Pfeffer: +0.7 points; p= 0.001; Z= -3.38. Conclusions: After three years of follow-up we observed a discreet yet significant functional and cognitive decline in the subjects. Longitudinal cognitive screening represents an important strategy in the early identification of changes from normal conditions to a dementia process.

    1987-03-01

    This normative-descriptive case study of accountability for state school curriculum in South Australia has the following objectives. First, to seek to draw a distinction between accountability and responsibility: terms which have been confused by two South Australian Directors-General of Education (position akin to C.E.O. in the U.K. and Superintendent in the U.S.A.) with important consequences. Second, to present a model of accountability for state school curriculum, by which accountability for such curriculum may be judged democratic or non-democratic, and against which accountability for curriculum in South Australian state schools will be gauged. Third, to show that whilst the South Australian school system exhibits a large measure of bureaucratic or technocratic accountability for curriculum, there is no effective democratic accountability for curriculum, and to indicate a remedy for this situation. Finally, to point out the wider significance of the South Australian case study, and suggest that democracies currently re-structuring their educational systems would do well to keep the need for democratic accountability foremost in mind.

    Involvement in meal preparation and eating meals with the family are associated with better dietary patterns in adolescents, however little research has included older children or longitudinal study designs. This 3-year longitudinal study examines cross-sectional and longitudinal associations between family food involvement, family dinner meal frequency and dietary patterns during late childhood. Questionnaires were completed by parents of 188 children from Greater Melbourne, Australia at baseline in 2002 (mean age=11.25years) and at follow-up in 2006 (mean age=14.16years). Principal components analysis (PCA) was used to identify dietary patterns. Factor analysis (FA) was used to determine the principal factors from six indicators of family food involvement. Multiple linear regression models were used to predict the dietary patterns of children and adolescents at baseline and at follow-up, 3years later, from baseline indicators of family food involvement and frequency of family dinner meals. PCA revealed two dietary patterns, labeled a healthful pattern and an energy-dense pattern. FA revealed one factor for family food involvement. Cross-sectionally among boys, family food involvement score (β=0.55, 95% CI: 0.02, 1.07) and eating family dinner meals daily (β=1.11, 95% CI: 0.27, 1.96) during late childhood were positively associated with the healthful pattern. Eating family dinner meals daily was inversely associated with the energy-dense pattern, cross-sectionally among boys (β=-0.56, 95% CI: -1.06, -0.06). No significant cross-sectional associations were found among girls and no significant longitudinal associations were found for either gender. Involvement in family food and eating dinner with the family during late childhood may have a positive influence on dietary patterns of boys. No evidence was found to suggest the effects on dietary patterns persist into adolescence. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background The global rise of Type 2 diabetes and its complications has drawn attention to the burden of non-communicable diseases on populations undergoing epidemiological transition. The life course approach of a birth cohort has the potential to increase our understanding of the development of these chronic diseases. In 1987 we sought to establish an Australian Indigenous birth cohort to be used as a resource for descriptive and analytical studies with particular attention on non-communicable diseases. The focus of this report is the methodology of recruiting and following-up an Aboriginal birth cohort of mobile subjects belonging to diverse cultural and language groups living in a large sparsely populated area in the Top End of the Northern Territory of Australia. Methods A prospective longitudinal study of Aboriginal singletons born at the Royal Darwin Hospital 1987–1990, with second wave cross-sectional follow-up examination of subjects 1998–2001 in over 70 different locations. A multiphase protocol was used to locate and collect data on 686 subjects with different approaches for urban and rural children. Manual chart audits, faxes to remote communities, death registries and a full time subject locator with past experience of Aboriginal communities were all used. Discussion The successful recruitment of 686 Indigenous subjects followed up 14 years later with vital status determined for 95% of subjects and examination of 86% shows an Indigenous birth cohort can be established in an environment with geographic, cultural and climatic challenges. The high rates of recruitment and follow up indicate there were effective strategies of follow-up in a supportive population.

    The objectives of this study were to determine whether longitudinal changes in accelerometer-assessed moderate-to-vigorous physical activity (MVPA) were associated with changes in educational outcomes (i.e., academic performance and mathematics engagement) and to examine whether the association was nonlinear. Longitudinal data were collected from 2,194 Australian adolescents (mean age = 13.40 years, standard deviation = .73) at two time points (Term 1, 2014, and Term 2, 2015). To measure the total MVPA, the adolescents wore an accelerometer for seven consecutive days. The participants responded to a questionnaire to measure mathematics engagement and completed a nationally administered numeracy test to assess academic performance. Latent change score models indicated that increases in MVPA had a positive quadratic association with National Assessment Program-Literacy and Numeracy (NAPLAN) scores in girls (β = .39, p association with NAPLAN scores in grade 7 (β = .92, p = .04) boys and in grade 9 boys (β = .60, p = .06), but not in girls. There was also a positive quadratic association between MVPA and school engagement in grade 9 boys (β = .77, p = .03). Cross-sectional evidence indicated that boys who were more physically active had better educational outcomes than their less active peers, and girls who increased their regular physical activity showed improvements in academic performance. All students need to increase their physical activity levels for health and educational benefits, without compromising the time spent on study and homework. Crown Copyright © 2017.

    Catherine L Chojenta

    Full Text Available While previous studies have identified a range of potential risk factors for postnatal depression (PND, none have examined a comprehensive set of risk factors at a population-level using data collected prospectively. The aim of this study was to explore the relationship between a range of factors and PND and to construct a model of the predictors of PND.Data came from 5219 women who completed Survey 5 of the Australian Longitudinal Study on Women's Health in 2009 and reported giving birth to a child.Over 15% of women reported experiencing PND with at least one of their children. The strongest positive associations were for postnatal anxiety (OR = 13.79,95%CI = 10.48,18.13 and antenatal depression (OR = 9.23,95%CI = 6.10,13.97. Positive associations were also found for history of depression and PND, low SF-36 Mental Health Index, emotional distress during labour, and breastfeeding for less than six months.Results indicate that understanding a woman's mental health history plays an important role in the detection of those who are most vulnerable to PND. Treatment and management of depression and anxiety earlier in life and during pregnancy may have a positive impact on the incidence of PND.

    2017-10-01

    Analysing and understanding cryptomarkets is essential to become proactive in the fight against the illicit drug trade. Such a research seeks to combine a diversity of indicators related to the virtual (darknet markets) and physical (the traditional "offline" market) aspects of the illicit drug trade to provide information on the distribution and consumption as well as to assess similarities/differences between the virtual and physical markets. This study analysed data that had previously been collected on cryptomarkets from December 2013 to March 2015. In this article, the data was extracted from two marketplaces, Evolution and Silk Road 2, and analysed to evaluate the illicit drug trade of the Australian virtual market (e.g. information about the supply and demand, trafficking flows, prices of illicit drugs and market share) and highlight its specificities. The results revealed the domestic nature of the virtual Australian illicit drug trade (i.e. Australian sellers essentially ship their products to local customers). This may explain the coherence between supply and demand. Particularly, the virtual Australian illicit drug trade is dominated by amphetamine-type substances (ATS), mainly methamphetamine and 3,4-methylenedioxymethamphetamine (MDMA), and cannabis. Australia, as a shipping country, accounts for half of the methamphetamine offered and purchased on Silk Road 2. Moreover, it was observed that the online price fixed by Australian sellers for the considered illicit drugs is higher than for any other shipping countries, which is in line with previous studies. Understanding the virtual and physical drug market necessitates the integration and fusion of different perspectives to capture the dynamic nature of drug trafficking, monitor its evolution and finally improve our understanding of the phenomenon so policy makers can make informed decisions.

    2016-10-01

    Full Text Available Abstract Background Poor diet, characterized by a low diet quality score, has been associated with greater prevelence of obesity and hypertension. However, the evidence is inconsistent across diet quality scores and by sex. The aim was to investigate the relationship between diet quality and obesity and hypertension. Methods Adults (n = 4908; age 45.2 ± 0.24 years were included from the cross-sectional Australian Health Survey 2011–2013. Two 24-h dietary recalls were used to derive the dietary guideline index (DGI and recommended food score (RFS. Logistic regression investigated relationships between diet quality score and odds ratio of obesity, hypertension and obesity-associated hypertension. Results In the highest tertile of DGI, but not RFS, individuals were less likely to be obese (men: OR 0.64, CI: 0.45, 0.92, P-trend = 0.014; women: 0.68, 0.48, 0.96, P-trend = 0.025 and to have central adiposity (men: 0.68, 0.48, 0.97, P-trend = 0.030; women: 0.53, 0.37, 0.77, P-trend = 0.001 compared with the lowest tertile. Men, but not women, in the highest tertile of DGI and RFS were less likely to be hypertensive (DGI: 0.56, 0.37, 0.85, P-trend = 0.006; RFS: 0.62, 0.41, 0.94, P-trend = 0.021 compared with the lowest tertile. In men with obesity, but not normal weight men or women, those in the highest tertile of DGI were less likely to be hypertensive (0.53, 0.36, 0.78, P-trend = 0.001 compared with the highest tertile. Conclusions Higher diet quality, as estimated using DGI, was associated with lower odds ratio of obesity in men and women. Odds ratio of hypertension was lower in men, but not women, with a high diet quality score compared with a low score, while obesity-associated hypertension was only associated with diet quality score in men with obesity. Longitudinal studies are needed to evaluate whether diet quality predicts risk of obesity and hypertension.

    Modern accelerator applications, such as heavy ion fusion drivers, pulsed neutron sources, electron injectors for high-energy linear colliders, and X-ray Free Electron Lasers, demand beams with high intensity, low emittance and small energy spread. At low (non-relativistic) energies, the "electrostatic", collective interactions from space-charge forces existing in such intense beams play the dominant role; we characterize these beams as space-charge dominated beams. This dissertation presents numerous new findings on the longitudinal dynamics of a space-charge dominated beam, particularly on the propagation of density perturbations. In order to fully understand the complex physics of longitudinal space-charge waves, we combine the results of theory, computer simulation, and experiment. In the Long Solenoid Experimental system (LSE), with numerous diagnostic tools and techniques, we have, for the first time, experimentally measured the detailed energy profiles of longitudinal space-charge waves at different locations, both near the beam source and at the end of the transport system. Along with the current profiles, we have a complete set of experimental data for the propagation of space-charge waves. We compare these measured results to a 1-D theory and find better agreement for beams with perturbations in the linear regime, where the perturbation strength is less than 10%, than those with nonlinear perturbations. Using fast imaging techniques that we newly developed, we have, for the first time, obtained the progressive time-resolved images of longitudinal slices of a space-charge dominated beam. These images not only provide us time-resolved transverse density distribution of the beam, but also enable us to take time-resolved transverse phase space measurement using computerized tomography. By combining this information with the longitudinal energy measurement, we have, for the first time, experimentally constructed the full 6-D phase space. Part of the results

    Many children are not physically active enough for a health benefit. One avenue of physical activity is modified sport programs, designed as an introduction to sport for young children. This longitudinal study identified trends in participation among children aged 4-12 years. Outcomes included continuation in the modified sports program, withdrawal from the program or transition to club sport competition. De-identified data on participant membership registrations in three popular sports in the Australian state of Victoria were obtained from each sport's state governing body over a 4-year period (2009-2012 for Sport A and 2010-2013 for Sports B and C). From the membership registrations, those who were enrolled in a modified sports program in the first year were tracked over the subsequent three years and classified as one of: transition (member transitioned from a modified sport program to a club competition); continue (member continued participation in a modified sport program; or withdraw (member discontinued a modified program and did not transition to club competition). Many modified sports participants were very young, especially males aged 4-6 years. More children withdrew from their modified sport program rather than transitioning. There were age differences between when boys and girls started, withdrew and transitioned from the modified sports programs. If we can retain children in sport it is likely to be beneficial for their health. This study highlights considerations for the development and implementation of sport policies and programming to ensure lifelong participation is encouraged for both males and females.

    To assess the number of pathology tests ordered by general practice registrars during their first 18-24 months of clinical general practice. Longitudinal analysis of ten rounds of data collection (2010-2014) for the Registrar Clinical Encounters in Training (ReCEnT) study, an ongoing, multicentre, cohort study of general practice registrars in Australia. The principal analysis employed negative binomial regression in a generalised estimating equations framework (to account for repeated measures on registrars).Setting, participants: General practice registrars in training posts with five of 17 general practice regional training providers in five Australian states. The registrar participation rate was 96.4%. Number of pathology tests requested per consultation. The time unit for analysis was the registrar training term (the 6-month full-time equivalent component of clinical training); registrars contributed data for up to four training terms. 876 registrars contributed data for 114 584 consultations. The number of pathology tests requested increased by 11% (95% CI, 8-15%; P pathology test ordering by general practice registrars increased significantly during their first 2 years of clinical practice. This causes concerns about overtesting. As established general practitioners order fewer tests than registrars, test ordering may peak during late vocational training and early career practice. Registrars need support during this difficult period in the development of their clinical practice patterns.

    The prevalence of fear of birth has been estimated between 8-30%, but there is considerable heterogeneity in research design, definitions, measurement tools used and populations. There are some inconclusive findings about the stability of childbirth fear. to assess the prevalence and characteristics of women presenting with scores ≥60 on FOBS-The Fear of Birth Scale, in mid and late pregnancy, and to study change in fear of birth and associated factors. A prospective longitudinal cohort study of a one-year cohort of 1212 pregnant women from a northern part of Sweden, recruited in mid pregnancy and followed up in late pregnancy. Fear of birth was assessed using FOBS-The fear of birth scale, with the cut off at ≥60. The prevalence of fear of birth was 22% in mid pregnancy and 19% in late pregnancy, a statistically significant decrease. Different patterns were found where some women presented with increased fear and some with decreased fear. The women who experienced more fear or less fear later in pregnancy could not be differentiated by background factors. More research is needed to explore factors important to reduce fear of childbirth and the optimal time to measure it. Copyright © 2017 Australian College of Midwives. Published by Elsevier Ltd.

    The World Health Organization (WHO) stated that globally, dental caries is the most important oral condition. To develop effective prevention strategies requires an understanding of how this condition develops and progresses over time, but there are few longitudinal studies of caries onset and progression in children. The aim of the study was to establish the pattern of caries development from childhood into adolescence and to explore the role of potential risk factors (age, sex, ethnicity, and social deprivation). Of particular interest was the disease trajectory of dentinal caries in the permanent teeth in groups defined by the presence or absence of dentinal caries in the primary teeth. Intraoral examinations to assess oral health were performed at 4 time points by trained and calibrated dentist examiners using a standardized, national diagnostic protocol. Clinical data were available from 6,651 children. Mean caries prevalence (% D 3 MFT > 0) was 16.7% at the first clinical examination (ages 7-9 y), increasing to 31.0%, 42.2%, and 45.7% at subsequent examinations. A population-averaged model (generalized estimating equations) was used to model the longitudinal data. Estimated mean values indicated a rising D 3 MFT count as pupils aged (consistent with new teeth emerging), which was significantly higher (4.49 times; 95% confidence interval, 3.90-5.16) in those pupils with caries in their primary dentition than in those without. This study is one of the few large longitudinal studies to report the development of dental caries from childhood into adolescence. Children who developed caries in their primary dentition had a very different caries trajectory in their permanent dentition compared to their caries-free contemporaries. In light of these results, caries-free and caries-active children should be considered as 2 separate populations, suggesting different prevention strategies are required to address their different risk profiles.

    With the ongoing development of Australian anthropogenic climate change mitigation policies, there has been a steady increase in modelling studies undertaken to estimate Australian carbon prices and their impact on existing electricity markets. This article summarises some of the more prominent studies completed by many of Australia’s foremost economic modelling firms. We developed a simple approach for testing the consistency of these studies and their findings in relation to carbon pass-through. Unfortunately, we have established that the studies are entirely inconsistent in their estimation of carbon pass-through. Furthermore, we were unable to establish why the estimation of carbon pass-through varies so significantly. This has important implications for policy makers given much of the compensation to be paid to households and businesses under the Clean Energy Future package is predicated on simple assumptions of carbon pass-through. Based upon our analysis of these economic studies, our conclusion is that Australian policy makers are best guided by relying upon the numerous a posteriori estimations of pass-through in the European Union Emissions Trading Scheme (ETS) rather than Australian a priori studies. - Highlights: ► This article summarises prominent studies of Australia's leading economic modelling firms. ► We developed a simple approach for testing estimations of carbon pass-through. ► We found that the average rate of pass-through was similar to the market's average intensity (93.45%). ► We established that the studies vary significantly in their estimation of carbon pass-through. ► We believe that further research is required to explain why the studies vary so significantly.

    Colorectal cancer (CRC) is a common malignancy. There is growing evidence that CRC incidence is increasing in the younger population. There is controversy surrounding the prognosis of young patients with CRC. In this study we reviewed Australian patients with metastatic CRC (mCRC) who were younger than 40 years of age at the time of diagnosis of metastatic disease. To our knowledge this is the first study to focus on this age group with mCRC. This was a retrospective study using data from the South Australian Metastatic Colorectal Cancer database. We compared patient and disease characteristics, management approaches, and outcomes for age groups Young-onset mCRC patients, when defined as aged younger than 40 years, have equivalent survival compared with their older counterparts. This is despite differences in disease characteristics and management approach between the 2 groups. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Introduction. There is debate as to whether physical activity counteracts the adverse effect of weight on health outcomes. We investigated how physical activity modifies the effect of body mass index (BMI on hypertension risk. Methods. BMI, physical activity, and hypertension were measured at baseline and at three-year interval for 14 years (from 1996 to 2010, in 10,339 participants in the Australian Longitudinal Study on Women’s Health. Generalised estimating equation models for binary repeated measures were performed to determine the individual and joint effects of BMI and physical activity on incident hypertension. Results. At baseline (mean age 47.6±1.5 SD, 57% were healthy weight, 28% overweight, and 14% obese. Increasing BMI and decreasing physical activity were associated with increased risk of hypertension. Physical activity attenuated the positive association between weight and risk of hypertension, especially for obese women. Compared to healthy weight high active women, risk of hypertension in obese high active women was 3.4 times greater (OR 3.43, 95% CI 2.68, 4.39 and in obese inactive women 4.9 times greater (OR 4.91, 95% CI 3.92, 6.13. Conclusions. Both physical activity and maintenance of a healthy body weight are associated with lower risk of hypertension. Physical activity reduced but did not remove the effect of obesity on hypertension risk.

    Pregnancy is an important stage in life for many women. Humans are complex organisms that are prone to exhibiting gradual alterations in their constitutions that fluctuate with age, diet, and living environment. This is particularly true during the pre- and postnatal periods, in which qi and blood are required to ensure foetal growth. To examine women's constitutional transformation of pre-pregnancy, pregnancy, and postpartum. A prospective, longitudinal study was conducted, and structural questionnaires were used to collect data. The participants were healthy pregnant women 21-49 years of age. Data were collected at six times: during the first (weeks 6-13), second (weeks 14-27), and third (weeks 28-40) trimesters and during the postnatal admission (1-week postnatal) and home self-care (6-week and 6-month postnatal) periods, yielding 86 valid questionnaires. A cubic polynomial regression analyses with generalised estimation equations (GEEs) method was used to reveal the trend of constitution score by different constitutions. Significant differences (p women's constitutions underwent changes throughout the perinatal stages. These findings provide a valuable reference for healthcare professionals in administering perinatal care and demonstrate empirical evidence for use in future intervention-based research.

    2013-01-01

    A three-wave, longitudinal study examined the long-term trajectory of problem gaming symptoms among adult regular video gamers. Potential changes in problem gaming status were assessed at two intervals using an online survey over an 18-month period. Participants (N=117) were recruited by an advertisement posted on the public forums of multiple Australian video game-related websites. Inclusion criteria were being of adult age and having a video gaming history of at least 1 hour of gaming every week over the past 3 months. Two groups of adult video gamers were identified: those players who did (N=37) and those who did not (N=80) identify as having a serious gaming problem at the initial survey intake. The results showed that regular gamers who self-identified as having a video gaming problem at baseline reported more severe problem gaming symptoms than normal gamers, at all time points. However, both groups experienced a significant decline in problem gaming symptoms over an 18-month period, controlling for age, video gaming activity, and psychopathological symptoms.

    To report the current knowledge on the Chinese nursing students' learning at Australian universities. The intent is to provide educators and researchers with a background to the contexts, the methodologies, the emphases of various relevant studies, and to provide recommendations for future research. Attracting international students has become an important part of Australian universities' business and contributes to their cultural diversity. Teaching international students has received considerable attention in the educational research literature. Experiences of international students can vary greatly depending on their country of origin. This paper critically reviews current literature relating to issues for Chinese students and in particular, Chinese nursing students, the biggest single group of international nursing students at Australian universities Narrative literature review. A comprehensive search of seven electronic databases for literature between 2003 and 2014 helped to identify qualitative and quantitative studies that addressed issues of Asian international students with English as a second language (ESL) (included nursing students) studying in Australia, New Zealand, the UK, the United States and China. Pertinent websites were also searched. The reference lists and bibliographies of retrieved articles were hand- searched to identify other relevant studies. Fifteen studies met the inclusion criteria for the review. The majority of existing literature claimed that there is a range of challenges confronting international students including Chinese nursing students, in assimilation into their host country. These include issues with English language proficiency, cultural barriers, social problems, different learning styles, academic demands, perceived racism, homesickness, lack of assertiveness and financial problems. There is limited research about the Chinese students' study in Australia. In particular, the learning experience of Chinese nursing students

    To examine the relationship between early life episodes of otitis media and later behavioural development with adjustment for confounders. Longitudinal cohort study. The Western Australian Pregnancy Cohort (Raine) Study recruited 2900 pregnant women from King Edward Memorial Hospital (KEMH) in Perth, Western Australia, between 1989 and 1991. Data from the children born were collected at both the Year 3 and Year 5 follow up. At Year 3, n = 611 were diagnosed with recurrent otitis media through parent-report and clinical examination. At Year 5, n = 299 were considered exposed to otitis media based upon tympanometry results. Performance in the Child Behaviour Checklist (CBCL), a questionnaire completed by the primary caregiver at Year 10. Significant associations were found between recurrent otitis media at Year 3 and internalising behaviours (P = 0.011), and the somatic (P = 0.011), withdrawn (P = 0.014), attention (P = 0.003) and thought problems domains (P = 0.021), and the total CBCL score (P = 0.010). A significant association was also found between exposure to otitis media at Year 5 and externalising behaviours (P = 0.026). A modest association was seen between recurrent otitis media at Year 3 and exposure to otitis media at Year 5 and a number of behaviour domains at Year 10. This article is protected by copyright.

    2012-11-01

    Full Text Available There was something peculiar about meeting Bruce Bennett. Chances to see Bruce in Europe were much higher than getting hold of him in Australia. The first time we met was neither in Australia nor in Europe, but in Kolkata, India. This was at the 2008 IASA conference, one of the biennial meetings of the Indian Association for the Study of Australia. Bruce was surrounded by a bevy of Indian scholars, especially students, eager to ask for his advice or simply having a chat about their papers over coffee. Bruce had always had an open ear for everyone. He was interested in talking to students and emerging scholars alike. An eminent authority on Australian literature and culture, Bruce was not only preoccupied with ‘big’ names. He also engaged with young scholars of Australian studies.

  1. Exploring Australian Aboriginal Women’s experiences of menopause: a descriptive study

    2014-01-01

    Background Despite extensive literature demonstrating differing experiences in menopause around the world, documentation of the experience of menopause in Australian Aboriginal women is scarce, and thus their menopausal experience is relatively unknown. This study aimed to understand Australian Aboriginal women’s understanding and experience of menopause and its impact on their lives. Methods The study was an exploratory qualitative study. Twenty-five Aboriginal women were recruited from a regional centre in the Mid-West region of Western Australia using opportunistic and snowballing sampling. Interviews and focus group discussions were undertaken from February 2011 to February 2012 using open-ended questioning with a yarning technique. Thematic analysis was undertaken of the transcribed interviews. Results A number of themes were revealed. These related to the language used, meanings and attitudes to menopause, symptoms experienced, the role of men, a lack of understanding, coping mechanisms and the attribution of menopausal changes to something else. The term “change of life” was more widely recognised and signified the process of ageing, and an associated gain of respect in the local community. A fear of menopausal symptoms or uncertainty about their origin was also common. Overall, many women reported insufficient understanding and a lack of available information to assist them and their family to understand the transition. Conclusion There are similarities between Aboriginal and non-Aboriginal experiences of menopause, including similar symptom profiles. The current language used within mainstream health settings may not be appropriate to this population if it fails to recognise the importance of language and reflect the attributed meaning of menopause. The fear of symptoms and uncertainty of their relationship to menopause demonstrated a need for more information which has not adequately been supplied to Australian Aboriginal women through current

    2012-01-01

    Full Text Available Abstract Background Overall the physical health of Indigenous men is among the worst in Australia. Research has indicated that modifiable lifestyle factors, such as poor nutrition and physical inactivity, appear to contribute strongly to these poor health conditions. To effectively develop and implement strategies to improve the health of Australia's Indigenous peoples, a greater understanding is needed of how Indigenous men perceive health, and how they view and care for their bodies. Further, a more systematic understanding of how sociocultural factors affect their health attitudes and behaviours is needed. This article presents the study protocol of a community-based investigation into the factors surrounding the health and body image of Indigenous Australian men. Methods and design The study will be conducted in a collaborative manner with Indigenous Australian men using a participatory action research framework. Men will be recruited from three locations around Australia (metropolitan, regional, and rural and interviewed to understand their experiences and perspectives on a number of issues related to health and health behaviour. The information that is collected will be analysed using modified grounded theory and thematic analysis. The results will then be used to develop and implement community events in each location to provide feedback on the findings to the community, promote health enhancing strategies, and determine future action and collaboration. Discussion This study will explore both risk and protective factors that affect the health of Indigenous Australian men. This knowledge will be disseminated to the wider Indigenous community and can be used to inform future health promotion strategies. The expected outcome of this study is therefore an increased understanding of health and health change in Indigenous Australian men, the development of strategies that promote healthy eating and positive patterns of physical activity and, in

    The study aimed to test if there was an association between prevalent bacterial vaginosis (BV) and women reporting that their partner had other partners at the same time (partner concurrency). This association has not been assessed in a longitudinal cohort. The Longitudinal Study of Vaginal Flora recruited a cohort of 3620 non-pregnant women aged 15-44 years who presented for routine primary healthcare at 12 clinics in Birmingham, Alabama. Behavioural questionnaires and vaginal smears were obtained quarterly for a year and BV was defined by a Nugent score 7 or higher as well as Amsel criteria. Mixed effects logistic regression was used to assess the relationship between prevalent BV and reporting that one's partner had other partners in the preceding 3-6 months time interval. Nugent score prevalent BV was associated with both reporting that one's partner definitely (adjusted OR (aOR) 1.5; 95% CI 1.2 to 1.8) and possibly (aOR 1.5; 95% CI 1.2 to 1.8) engaged in partner concurrency in the preceding 3-6 months time period. Prevalent BV diagnosed by Amsel criteria was similar. A diagnosis of prevalent BV was associated with reporting that one's partner possibly or definitely engaged in partner concurrency.

    2007-09-01

    Full Text Available This study reports on research that examined DEST data from 14 Australian universities to identify the diversity of journal outlets in the information systems (IS area. Across a total of 60 years of academic publishing output, 1449 journal articles were evaluated to identify 649 different journals in which IS-related articles were published. The most popular journals used by Australian academics to publish IS-related articles were the Lecture Notes in Computer Science (N=94 in the computer science area, with the Australasian Journal of Information Systems (N=25 being the most popular journal in the pure and business IS sphere. The study also examined publishing output against a set of 50 previously highly rated IS journals and concluded that the average annual publication of articles in these highly rated journals occurred at a very low rate. The research appears to be one of the first studies to use historical DEST data to report journal diversity in the Australian IS-sphere.

    Australia's renewable energy target (RET) seeks to provide 20 per cent of Australia's electricity generation from renewable energy sources by 2020. As wind power is relatively advanced, it was anticipated that wind power will contribute a major component of the early target. However, high levels of societal resistance to wind farms, combined with new regulatory policies, indicate the RET may not be dominated by wind power. This research involved an examination of seven case studies around wind farm deployment. Qualitative interviews were the primary data for the case studies and analysed using methods informed by grounded theory. Despite the diversity of stakeholder views, the qualitative analysis identified strong community support for wind farms but four common themes emerged that influence this societal acceptance of wind farms in Australia: trust, distributional justice, procedural justice and place attachment. Without addressing these factors through integration into policy development and engagement approaches, wind energy is unlikely to provide the early and majority of new renewable energy. Similar international experiences are incorporated in the discussion of the Australian wind industry's societal acceptance. - Highlights: ► Seven case studies of wind farms in Australia are described. ► Acceptance affects whether wind significantly contributes to the Aust. RE target. ► Four themes were identified regarding societal acceptance of Australian wind farms. ► Four themes are trust, distributional and procedural justice, and place attachment. ► International similarities to the Australian experience are provided

    Young men can be difficult to engage in health research using traditional methods of recruitment. Social networking sites are increasingly being used to recruit participants into health research, due to their cost effectiveness, overall generalizability, and wide reach. The aim of this study was to determine the feasibility of using Facebook to recruit young Australian men into a human papillomavirus (HPV) prevalence study. We recruited male permanent residents of Australia, aged 18 to 35 years, into the HPV in Young Males (HYM) study through targeted advertising placed on Facebook. Consenting participants completed an online questionnaire and provided a self-collected penile swab for HPV DNA detection and genotyping. We compared sociodemographic characteristics of the study population with those of the general Australian male population, based on Australian 2011 census data. Between February 2015 and February 2017, targeted Facebook advertisements reached 1,523,239 men, resulting in 41,811 clicks through to the study website, with 1072 (2.56%) converting to lodgment of an expression of interest. Of these, 681 (63.53%) provided written informed consent and 535 (78.6% of recruited participants) completed all the study requirements. Reasons for participating in the study included altruism, past history of HPV, gaining more knowledge about HPV or the vaccine, working in the health industry, and the monetary compensation. The average advertising cost per completed study participant was Aus $48. Compared with the census population, HYM study participants were more likely to be Australian born (PFacebook is a feasible and efficient strategy for the recruitment of men from across Australia for HPV testing. This method could be used for monitoring the impact of HPV vaccination. Additional targeting may achieve a sample that is broadly demographically representative of the Australian population. Future research should explore how the sexual risk behavior characteristics of

    The purpose of the present study was to extend the external validity of an earlier longitudinal study of school leavers by including participants from a representative sample of secondary schools. Questionnaires were administered annually to a sample of South Australian school leavers over a 10-year period. At Time 1 participants were in the last compulsory year of high school aged around 15 years and at Time 10 they were aged around 25 years. Results confirmed those from an earlier longitudinal study showing that the transition from school to satisfactory employment was associated with significant improvements in psychological well-being, whereas transition from school to unemployment or unsatisfactory employment showed no change in psychological well-being. The current findings extended the external validity of the earlier study because whereas participants in the earlier study were sampled from co-educational metropolitan public high schools, the current study included participants from every kind of high school: single sex as well as co-educational, rural as well as metropolitan, and private as well as public.

    Numerous surveys identify the occurrence of musculoskeletal complaints as a concern in dentistry. However, no longitudinal data exist to indicate whether postural changes occur as a result of practicing dental hygiene. The purpose of this preliminary, four-year longitudinal study was to investigate whether any postural changes developed during the hygienists' clinical education and/or during subsequent dental hygiene practice after one and/or two years. It was anticipated that the awkward positions and intense physical demands placed on hygienists might initiate musculoskeletal problems, but that no postural changes would occur over this short period of time. Nine of 10 dental hygienists in the graduating class of 1987 were surveyed for existing musculoskeletal complaints, and the subjects were photographed for a measurement of postural change. Responses from participants indicated an increase in musculoskeletal-related complaints in each of the six areas investigated. The photographic findings indicated that one of the nine hygienists showed an increase in forward head posture, a postural change.

    The course of depression from pregnancy to 1 year post partum and risk factors among mothers and fathers are not known. (1) To report the longitudinal patterns of depression from the third trimester of pregnancy to 1 year after childbirth; (2) to determine the gender differences between women and their partners in the effect of psychosocial and personal factors on postpartum depression. A longitudinal cohort study was carried out over a consecutive sample of 769 women in their third trimester of pregnancy and their partners attending the prenatal programme in the Valencian Community (Spain) and follow-up at 3 and 12 months post partum. The outcome variable was the presence of depression at 3 or 12 months post partum measured by the Edinburgh Postnatal Depression Scale. Predictor variables were: psychosocial (marital dissatisfaction, confidant and affective social support) and personal (history of depression, partner's depression and negative life events, depression during the third trimester of pregnancy) variables. Logistic regression models were fitted via generalised estimating equations. At 3 and 12 months post partum, 9.3% and 4.4% of mothers and 3.4% and 4.0% of fathers, respectively, were newly diagnosed as having depression. Low marital satisfaction, partner's depression and depression during pregnancy increased the probability of depression during the first 12 months after birth in mothers and fathers. Negative life events increased the risk of depression only among mothers. Psychosocial and personal factors were strong predictors of depression during the first 12 months post partum for both mothers and fathers.

    We conducted a 5-year longitudinal study on 76 workers of a high and medium aluminium alloy die-casting factory. As in a previous cross-sectional study conducted in 1986 and in accordance with the data in the literature, the 1990 follow-up study showed: a low prevalence of chronic bronchitis (as defined by the ECSC questionnaire on respiratory symptoms); normal mean functional values of FVC, FEV1, FEV1/FVC%. We did not find any significant difference in the levels of lung function over the period of 1986-90. These results show that workers in the secondary aluminium industry are not exposed to a significant risk of chronic pulmonary disease.

    Full Text Available This database has been constructed to support a program of work designed to untangle genetic and environmental contributions to the risk for schizophrenia and other adverse outcomes in the offspring of mothers with schizophrenia and other severe mental illness. To do this, it utilises Western Australian whole-population health and social services databases. Records on the Western Australian psychiatric case register have been linked to Midwives’ Notification of Birth records and to Registrations of Births (for paternal links as well as to other data sets. Maternal links identify women with psychosis who gave birth in Western Australia between 1980 and 2001. Comparison mothers are those with no record of psychiatric illness who gave birth in Western Australia over the same period. The study database comprises 246,873 mothers and 467,945 children: 889 mothers with schizophrenia (1,672 children; 1,644 mothers with bipolar disorder (3,358 children; 4,200 mothers with unipolar major depression (8,864 children; 775 mothers with other psychoses (1,592 children; and 239,365 comparison mothers (452,459 children. Full psychiatric histories for mothers, fathers and children have been extracted. At the time of the most recent update to the psychiatric data on children, 33,363 children had a history of psychiatric illness; 5,500 of these had had at least one contact with mental health services at which a diagnosis of a psychotic disorder had been recorded. Data have also been collected on obstetric complications and a range of infant and childhood morbidities including birth defects, intellectual disability, educational achievement, childhood abuse, criminal offending. The program aims are to: (i determine the frequency and distribution of obstetric complications in women with schizophrenia compared to a non-psychiatric comparison group of mothers; (ii explore the spectrum of outcomes for the children born to women with schizophrenia compared to comparison

    Available evidence from cross-sectional studies suggests that childhood maltreatment may be associated with a range of sleep disorders. However, these studies have not controlled for potential individual-, familial- and environmental-level confounders. To determine the association between childhood maltreatment and lower sleep quality after adjusting for potential confounders. Data for the present study were obtained from a pre-birth cohort study of 3778 young adults (52.6% female) of the Mater Hospital-University of Queensland Study of Pregnancy follow up at a mean age of 20.6 years. The Mater Hospital-University of Queensland Study of Pregnancy is a prospective Australian pre-birth cohort study of mothers consecutively recruited during their first obstetric clinic visit at Brisbane's Mater Hospital in 1981-1983. Participants completed the Pittsburgh Sleep Quality Index at the 21-year follow up. We linked this dataset to agency-recorded substantiated cases of childhood maltreatment. A series of separate logistic regression models was used to test whether childhood maltreatment predicted lower sleep quality after adjustment for selected confounders. Substantiated physical abuse significantly predicted lower sleep quality in males. Single and multiple forms of childhood maltreatment, including age of maltreatment and number of substantiations, did not predict lower sleep quality in either gender in both crude and adjusted models. Not being married, living in a residential problem area, cigarette smoking and internalising were significantly associated with lower sleep quality in a fully adjusted model for the male-female combined sample. Childhood maltreatment does not appear to predict young adult poor sleep quality, with the exception of physical abuse for males. While childhood maltreatment has been found to predict a range of mental health problems, childhood maltreatment does not appear to predict sleep problems occurring in young adults. Poor sleep quality was

    To explore what Australian experts value in breast screening, how these values are conceptualised and prioritised, and how they inform experts' reasoning and judgement about the Australian breast-screening programme. Qualitative study based on interviews with experts. 33 experts, including clinicians, programme managers, policymakers, advocates and researchers selected for their recognisable influence in the Australian breast-screening setting. Australian breast-screening policy, practice and research settings. Experts expressed 2 types of values: ethical values (about what was good, important or right) and epistemological values (about how evidence should be created and used). Ethical values included delivering benefit, avoiding harm, promoting autonomy, fairness, cost effectiveness, accountability, professionalism and transparency. Epistemological values informed experts' arguments about prioritising and evaluating evidence methodology, source population and professional interests. Some values were conceptualised differently by experts: for example, delivering benefit could mean reducing breast cancer mortality, reducing all-cause mortality, reducing mortality in younger women, reducing need for aggressive treatment, and/or reassuring women they were cancer free. When values came into conflict, experts prioritised them differently: for example, when experts perceived a conflict between delivering benefits and promoting autonomy, there were differences in which value was prioritised. We explain the complexity of the relationship between held values and experts' overall views on breast cancer screening. Experts' positions in breast screening are influenced by evidence and a wide range of ethical and epistemological values. We conclude that discussions about values should be a regular part of breast-screening review in order to build understanding between those who hold different positions, and provide a mechanism for responding to these differences.

    Full Text Available There is increasing concern about family homelessness. Homeless mothers and their children are one of society’s most disadvantaged and at-risk populations. However, very little Australian research exploring mothers’ views on their homelessness experiences exists. Using semi-structured interviews with 14 mothers and four agency staff, this study explored homeless Australian mothers’ pathways into and out of homelessness, their specific needs and the services and supports that were (or would have been most helpful. In this sample of single mothers and their children, early experiences of homelessness and domestic violence contributed most commonly to homelessness episodes. Almost immediate engagement with welfare agencies seemed to be protective against re-experiencing homelessness, however Australian restrictions on length of program involvement and limited housing options for mothers exiting homelessness programs, may place such mothers and their children at high risk of re-entering homelessness. Younger mothers had greater needs and benefited most from personalised one-on-one support that addressed key parenting and life skills. The implications of these findings are considered in relation to service delivery to this vulnerable group and avenues for future research are noted.

    Sustaining a fall during hospitalization reduces a patient's ability to return home following discharge. It is well accepted that factors, such as alteration in balance, functional mobility, muscle strength, and fear of falling, are all factors that impact on the quality of life of elderly people following a fall. However, the impact that falls have on mental health outcomes in older adult mental health patients remains unexplored. The present study reports Health of the Nation Outcome Scale scores for people over the age of 65 (HoNOS65+), which were examined in a cohort of 65 patients who sustained a fall and 73 non-fallers admitted to an older adult mental health service (OAMHS). Results were compared with state and national HoNOS65+ data recorded in Australian National Outcome Casemix Collection data to explore the effect that sustaining a fall while hospitalized has on mental health outcomes. Australian state and national HoNOS65+ data indicate that older adults generally experience improved HoNOS65+ scores from admission to discharge. Mental health outcomes for patients who sustained a fall while admitted to an OAMHS did not follow this trend. Sustaining a fall while admitted to an OAMHS negatively affects discharge mental health outcomes. © 2015 Australian College of Mental Health Nurses Inc.

    Since 2011, Western Australian nursing and midwifery educators have been providing evidence-based continuing education to Tanzanian health professionals. Despite thorough preparation before departure, differences in local resource levels and available facilities have necessitated impromptu adaptation of curriculum content and delivery methods to ensure an effective program was delivered. This study explored the personal, cultural and teaching strategies utilised by Western Australian nursing and midwifery educators in Tanzania and examined if the transferability of education packages was influenced by the educators' cultural competence. Using a qualitative exploratory approach, data was collected from 15 Western Australian nursing and midwifery educators using a demographic survey and in-depth individual semi-structured interviews. The core themes identified from the analysis were Determination to learn, Assessing needs, Communication skills and Greater understanding. These findings are described using the conceptual framework of Campinha-Bacote's The Process of Cultural Competence in the Delivery of Healthcare Services. With appropriate levels of cultural competence, international health professionals can be effective at providing ongoing professional development to colleagues in developing country contexts, which may help address difficulties with retention and motivation of staff. It is essential that prior to departure cultural competence training is provided to educators to enhance their teaching capacity and effectiveness in international settings.

    This study longitudinally compared activity in the frontal cortex during a spatial working memory task between 5-year-old and 7-year-old children using near-infrared spectroscopy. Eight children participated in this study twice, once at 5 years and once at 7 years of age. Behavioral analysis showed that older children performed the working memory task more precisely and more rapidly than younger children. Near-infrared spectroscopy analysis showed that right hemisphere dominance was observed in older children, whereas no hemispheric difference was apparent in younger children. Children with strengthened lateralization showed improved performance from 5 to 7 years. We therefore offer the first demonstration of the developmental changes in frontal cortical activation during spatial working memory tasks during the preschool period.

    Models of speech learning suggest that adaptations to foreign language sound categories should happen early in the acquisition process. Results from laboratory language training show effects on non-native perception within one to three weeks of training. Results from linguistic immersion studies...... show differences in adaptations when contrasting averages of 1-2 yrs of experience with 6-7 yrs of experience. We investigated this apparent discrepancy in a longitudinal study on Danish language officer cadets learning either Arabic (MSA and Egyptian dialect) or Dari (Afghan Farsi) through intensive......

    The aim of this study was to examine changes in passive length and stiffness of the gastrocnemius muscle-tendon unit in people after spinal cord injury. In a prospective longitudinal study, eight wheelchair-dependent participants with severe paralysis were assessed 3 and 12 mos after spinal cord injury. Passive torque-angle data were obtained as the ankle was slowly rotated through range at six knee angles. Differences in passive ankle torque-angle data recorded at different knee angles were used to derive passive length-tension curves of the gastrocnemius muscle-tendon unit. Ultrasound imaging was used to determine fascicle and tendon contributions to the muscle-tendon unit length-tension curves. The participants had ankle contractures (mean [SD] maximum passive ankle dorsiflexion angle, 88 [9] degrees) 3 mos after spinal cord injury. Ankle range did not worsen significantly during the subsequent 9 mos (mean change, -5 degrees; 95% confidence interval, -16 to 6 degrees). There were no changes in the mean slack length or the stiffness of the gastrocnemius muscle-tendon unit or in the slack lengths of the fascicles or the tendon between 3 and 12 mos after spinal cord injury. There were no consistent patterns of the change in slack length or stiffness with the changes in ankle range in the data from the individual participants. This study, the first longitudinal study of muscle length and stiffness after spinal cord injury, showed that the length and the stiffness of the gastrocnemius did not change substantially between 3 and 12 mos after injury.

    Little research has been conducted regarding the comprehensive health service utilisation in constipation care. This study investigates the comprehensive health service utilisation amongst Australian women with constipation. This study draws upon data from the Australian Longitudinal Study on Women's Health. A total of 8074 young women were asked about their frequency of constipation, measures of quality of life, and use of a range of health services and self-prescribed treatments via two postal surveys conducted in 2006 and 2009, respectively. The prevalence of constipation was 18.5% amongst women in 2009. Constipated women had poorer quality of health than women without constipation. Women who sought help for constipation were more likely to visit multiple groups of conventional and complementary health practitioners compared to women who did not experience constipation (pconstipation over time (2006 to 2009). There was an increase in the proportion of women with constipation who self-prescribed vitamins/minerals over time (pconstipation, given the increasing use of multiple health services across time, more studies are required regarding the optimal treatment in constipation care.

    Following childbirth, a vast number of women experience some degree of mood swings, while some experience symptoms of postpartum posttraumatic stress disorder. Using a biopsychosocial model, the primary aim of this study was to identify predictors of posttraumatic stress disorder and its symptomatology following childbirth. This observational, longitudinal study included 372 postpartum women. In order to explore biopsychosocial predictors, participants completed several questionnaires 3-5 days after childbirth: the Impact of Events Scale Revised, the Big Five Inventory, The Edinburgh Postnatal Depression Scale, breastfeeding practice and social and demographic factors. Six to nine weeks after childbirth, participants re-completed the questionnaires regarding psychiatric symptomatology and breastfeeding practice. Using a multivariate level of analysis, the predictors that increased the likelihood of postpartum posttraumatic stress disorder symptomatology at the first study phase were: emergency caesarean section (odds ratio 2.48; confidence interval 1.13-5.43) and neuroticism personality trait (odds ratio 1.12; confidence interval 1.05-1.20). The predictor that increased the likelihood of posttraumatic stress disorder symptomatology at the second study phase was the baseline Impact of Events Scale Revised score (odds ratio 12.55; confidence interval 4.06-38.81). Predictors that decreased the likelihood of symptomatology at the second study phase were life in a nuclear family (odds ratio 0.27; confidence interval 0.09-0.77) and life in a city (odds ratio 0.29; confidence interval 0.09-0.94). Biopsychosocial theory is applicable to postpartum psychiatric disorders. In addition to screening for depression amongst postpartum women, there is a need to include other postpartum psychiatric symptomatology screenings in routine practice.

    Diesel engines are widely used in occupational settings. Diesel exhaust has been classified as a lung carcinogen, but data on number of workers exposed to different levels of diesel exhaust are not available in Australia. The aim of this study was to estimate the current prevalence of exposure to diesel engine exhaust in Australian workplaces. A cross-sectional survey of Australian males and females (18-65 years old) in current paid employment was undertaken. Information about the respondents' current job and various demographic factors was collected in a telephone interview using the web-based tool OccIDEAS. Semi-quantitative occupational exposure levels to diesel exhaust were assigned using programmed decision rules and numbers of workers exposed in Australia in 2011 were estimated. We defined substantial exposure as exposed at a medium or high level, for at least 5h per week. Substantial occupational exposure to diesel exhaust was experienced by 13.4% of the respondents in their current job. Exposure prevalence varied across states, ranging from 6.4% in the Australian Capital Territory to 17.0% in Western Australia. Exposures occurred mainly in the agricultural, mining, transport and construction industries, and among mechanics. Men (20.4%) were more often exposed than women (4.7%). Extrapolation to the total working population indicated that 13.8% (95% confidence interval 10.0-20.4) of the 2011 Australian workforce were estimated to be substantially exposed to diesel exhaust, and 1.8% of the workers were estimated to experience high levels of exposures in their current job. About 1.2 million Australian workers were estimated to have been exposed to diesel exhaust in their workplace in 2011. This is the first study to describe the prevalence of occupational diesel exhaust exposure in Australia and will enable estimation of the number of lung cancers attributable to diesel exhaust exposure in the workplace. © The Author 2015.

    Placental GH is thought to be responsible for the rise in maternal IGF-I during pregnancy and is considered to be important for fetal growth. In this prospective longitudinal study of healthy pregnant women, we investigated determinants of placental GH in maternal serum. Serum was obtained from 455...... women with normal singleton pregnancies at approximately 19 and 28 wk gestation. Serum placental GH concentrations were measured by a highly specific immunoradiometric assay, and fetal size was measured by ultrasound. Data on birth weight, gender, prepregnancy body mass index (BMI), parity, and smoking...... habits were obtained from medical records. Serum placental GH concentrations were detectable in serum from all women as early as 14 wk gestation and increased during pregnancy in all individuals (P GH levels at second examination were found to be higher in women carrying female fetuses...

    The purpose of the present article is to compare the individual, peer, family, and school risk and protective factors for both traditional and cyber-bullying victimization. This article draws on data from 673 students from Victoria, Australia, to examine Grade 7 (aged 12-13 years) predictors of traditional and cyber-bullying victimization in Grade 9 (aged 14-15 years). Participants completed a modified version of the Communities That Care youth survey. There were few similarities and important differences in the predictors of traditional and cyber-bullying victimization. For Grade 9 cyber-bullying victimization, in the fully adjusted model, having been a victim of traditional bullying in Grade 7 and emotional control in Grade 7 were predictors. For Grade 9 traditional bullying victimization, predictors were Grade 7 traditional bullying victimization, association with antisocial peers, and family conflict, with family attachment and emotional control marginally statistically significant. The use of evidence-based bullying prevention programs is supported to reduce experiences of both traditional and cyber-bullying victimization, as is the implementation of programs to assist students to regulate their emotions effectively. In addition, traditional bullying victimization may be reduced by addressing association with antisocial friends, family conflict, and bonding to families. © The Author(s) 2014.

    Full Text Available Background: Bone mass loss and muscle atrophy are the frequent complications occurring after spinal cord injury (SCI. The potential risks involved with these changes in the body composition have implications for the health of the SCI individual. Thus, there is a need to quantitate and monitor body composition changes accurately in an individual with SCI. Very few longitudinal studies have been reported in the literature to assess body composition and most include relatively small number of patients. The present prospective study aimed to evaluate the body composition changes longitudinally by DEXA in patients with acute SCI. Materials and Methods: Ninety five patients with acute SCI with neurological deficits were evaluated for bone mineral content (BMC, body composition [lean body mass (LBM and fat mass] by dual-energy X-ray absorptiometry during the first year of SCI. Results: There was a significant decrease in BMC ( P < 0.05 and LBM ( P < 0.05 and increase in total body fat mass (TBFM and percentage fat at infra-lesional sites. The average decrease was 14.5% in BMC in lower extremities, 20.5% loss of LBM in legs and 15.1% loss of LBM in trunk, and increase of 0.2% in fat mass in legs and 17.3% increased fat in the lower limbs at 1 year. The tetraplegic patients had significant decrease in arm BMC ( P < 0.001, arm LBM ( P < 0.01 and fat percentage ( P < 0.01 compared to paraplegics. Patients with complete motor injury had higher values of TBFM and fat percentage, but comparable values of BMC and LBM to patients with incomplete motor injury. Conclusions: Our findings suggest that there is a marked decrease in BMC and LBM with increase in adiposity during the first year of SCI. Although these changes depend on the level and initial severity of lesions, they are also influenced by the neurological recovery after SCI.

    This study aims to identify the prevalence and pattern of bruises in preschool children over time, and explore influential variables Prospective longitudinal study of children (chart, weekly for up to 12 weeks. The number and location of bruises were analysed according to development. Longitudinal analysis was performed using multilevel modelling. 3523 bruises recorded from 2570 data collections from 328 children (mean age 19 months); 6.7% of 1010 collections from premobile children had at least one bruise (2.2% of babies who could not roll over and 9.8% in those who could), compared with 45.6% of 478 early mobile and 78.8% of 1082 walking child collections. The most common site affected in all groups was below the knees, followed by 'facial T' and head in premobile and early mobile. The ears, neck, buttocks, genitalia and hands were rarely bruised (patterns, although having a sibling increased the mean number of bruises. There was considerable variation in the number of bruises recorded between different children which increased with developmental stage and was greater than the variation between numbers of bruises in collections from the same child over time. These data should help clinicians understand the patterns of 'everyday bruising' and recognise children who have an unusual numbers or distribution of bruises who may need assessment for physical abuse or bleeding disorders.

Methods: First-, second-, and third-year students at Monash University completed the Jefferson Scale of Empathy–Health Professional (JSE-HP in 2008, 2009, and 2010, and the resulting mean empathy scores were analyzed by course, year of course, year of study, age, and sex. Results: Midwifery students were found to have higher empathy levels than nursing and emergency health students. Second- and third-year students scored higher than their counterparts in the first year. Empathy levels dipped in 2009 and rose in 2010. Students aged 26–30 years and 31–35 years recorded higher scores than their younger colleagues, and female students were found to be more empathic than their male counterparts. Conclusion: The finding that empathy levels are relatively stable over the term of study contributes to the understanding of how empathy evolves over the course of study and offers insights into the importance of incorporating and promoting empathy in health care curricula.

    Diet quality indices score dietary intakes against recommendations, whereas dietary patterns consider the pattern and combination of dietary intakes. Studies evaluating both methodologies in relation to cardiometabolic health in a nationally representative sample are limited. The aim of the present study was to investigate the relationship between diet quality, dietary patterns and markers of cardiometabolic health in Australian adults. Dietary data, using two 24-h dietary recalls, were collected from adults in the cross-sectional Australian Health Survey 2011-2013 (n = 2121; 46.4 (SE 0.48) years). Diet quality was estimated using the Dietary Guideline Index (DGI). Dietary patterns (DPs), derived using reduced rank regression, were estimated using fiber density, SFA: PUFA and total sugars intake as intermediate markers. Multi-variable adjusted linear regression analyses were used to examine associations between diet quality and DPs and blood biomarkers, body mass index, waist circumference, diastolic and systolic blood pressure and an overall cardiometabolic risk score. DGI was associated with lower glucose (coef - 0.009, SE 0.004; P-trend = 0.033), body mass index (coef - 0.017, SE 0.007; P-trend = 0.019) and waist circumference (coef - 0.014, SE 0.005; P-trend = 0.008). Two dietary patterns were derived: dietary pattern-1 was characterized by higher intakes of pome fruit and wholegrain bread, while dietary pattern-2 was characterized by higher intakes of added sugars and tropical fruit. Dietary pattern-1 was associated with lower body mass index (coef - 0.028, SE 0.007; P-trendDietary pattern-2 was associated with lower HDL-cholesterol (coef - 0.026, SE 0.012; P-trend = 0.028). There was a trend towards lower diastolic blood pressure. No associations with other markers were observed. Better diet quality and healthier dietary patterns were primarily associated with favorable anthropometric markers of cardiometabolic health. Findings

  4. Detailed analysis of radon flux studies at Australian uranium projects

    2005-01-01

    The release of radon gas and radon progeny from uranium projects is a major issue during operation as well as for the design of rehabilitation works. In Australia, there have been a number of premining radon flux studies as part of the environmental investigation and potential development of recent uranium projects. There is also an increasing amount of operational data on radon fluxes and loads from various aspects of projects, such as tailings, waste rock and mills. Thus there exists much useful measured data which can be used to assess the design radon flux and load targets for rehabilitation. The main projects for which radon data exists includes Ranger, Olympic Dam, Beverley, Honeymoon, Jabiluka, Yeelirrie, Lake Way, Koongarra, Moline, Coronation Hill, Rockhole, Nabarlek, Rum Jungle, Port Pirie and Ben Lomond. To date, much of this data has not been systematically evaluated. The need to compile and assess this data is twofold. Firstly, to assess the loads released from uranium production as an input into life-cycle analyses of the nuclear fuel cycle, such as those undertaken by UNSCEAR and industry groups. Secondly, there is a need to set suitable design standards for radon flux for the rehabilitation of former and current uranium projects. This paper will present such a detailed compilation of radon fluxes and loads which can then be used as the basis for both life-cycle analyses as well as setting appropriate site-specific rehabilitation criteria for radon. The implications for former and current projects is then discussed as well as future data needs. Ultimately, there is a critical need for thorough baseline surveys prior to mining to ensure accurate assessments of changes to radon fluxes and loads. The data and analysis presented is considered applicable to all uranium projects in Australia, as well as being a useful model for considering such issues internationally

    Multiple sclerosis (MS) is a debilitating disease that causes significant morbidity within a young demographic. Diagnostic guidelines for MS have evolved, and imaging has played an increasingly important role in diagnosis over the last two decades. For imaging to contribute to diagnosis in a meaningful way, it must be reproducible. Consensus guidelines for MRI in MS exist to define correct sequence type and imaging technique, but it is not clear to what extent they are followed. This study reviewed MRI studies performed on Australian individuals presenting with a first clinical diagnosis of central nervous system demyelination (FCD) for adherence to published guidelines and discussed practical implementation of MS guidelines in light of recent updates. The Ausimmune study was a prospective case control study of Australian participants presenting with FCD from 2003 to 2006. Baseline cranial and spinal cord MRI studies of 226 case participants from four separate Australian regions were reviewed. MRI sequences were classified according to anatomical location, slice plane, tissue weighting and use of gadolinium-containing contrast media. Results were compared with the 2003 Consortium of Multiple Sclerosis Centres MRI protocol for the diagnosis of MS. The composition of core cranial MRI sequences performed varied across the 226 scans. Of the studies, 91% included sagittal fluid attenuated inversion recovery (FLAIR) sequences. Cranial axial T2-weighted, axial FLAIR and axial proton density-weighted sequences were performed in 88%, 60% and 16% (respectively) of scans. Only 25% of the studies included a T1-weighted contrast-enhanced sequence. Concordance with the guidelines in all sequences was very low (2). Only a small number of MRI investigations performed included all of the sequences stipulated by consensus guidelines. This is likely due to poor awareness in the imaging community of the guidelines and the rationale behind certain sequences. Radiologists with a sub

    Several risk factors for negative birth experience have been identified, but little is known regarding the influence of social and midwifery support on the birth experience over time. The aim of this study was to describe women's birth experience up to two years after birth and to detect the predictive role of satisfaction with social and midwifery support in the birth experience. A longitudinal cohort study was conducted with a convenience sample of pregnant women from 26 community health care centres. Data was gathered using questionnaires at 11-16 weeks of pregnancy (T1, n=1111), at five to six months (T2, n=765), and at 18-24 months after birth (T3, n=657). Data about sociodemographic factors, reproductive history, birth outcomes, social and midwifery support, depressive symptoms, and birth experience were collected. The predictive role of midwifery support in the birth experience was examined using binary logistic regression. The prevalence of negative birth experience was 5% at T2 and 5.7% at T3. Women who were not satisfied with midwifery support during pregnancy and birth were more likely to have negative birth experience at T2 than women who were satisfied with midwifery support. Operative birth, perception of prolonged birth and being a student predicted negative birth experience at both T2 and T3. Perception of negative birth experience was relatively consistent during the study period and the role of support from midwives during pregnancy and birth had a significant impact on women's perception of birth experience.

    Information on the rate and spectrum of snowboarding injuries is limited. This 4-year prospective study at 3 major Australian ski resorts assesses incidence and patterns of snowboarding injuries, particularly in relation to skill level and footwear. Ski injury data were collected for the same period. In a predominantly male study population (men:women, 3:1), 276 snowboarding injuries were reported; 58% occurred in novices. Fifty-seven percent of injuries were in the lower limbs, 30% in the upper limbs. The most common injuries were sprains (53%), fractures (24%), and contusions (12%). Comparing skiers' versus snowboarders' injuries, snowboarders had 2.4 times as many fractures, particularly to the upper limbs (21% versus 35% of upper limb injuries), fewer knee injuries (23% versus 44% of lower limb injuries), but more ankle injuries (23% versus 6% of lower limb injuries). Ankle injuries were more common with soft-shell boots, worn most by intermediate and advanced riders. Knee injuries and distal tibial fractures were more common with hard-shell boots, worn most by novices. Overall, novices had more upper limb fractures and knee injuries; intermediate and advanced riders had more ankle injuries. Falls were the principal mode of injury. To prevent injury, beginners should use "hybrid" or soft-shell boots and take lessons.

    Evidence supporting the association between skipping breakfast and children's body mass index (BMI) has been widely reported, and some consideration has been given to children aged 2-5 years. However, no evidence has considered an association between children skipping breakfast and mother's BMI. This study therefore investigated associations between skipping breakfast, child's BMI and mother's BMI in a large cohort of Australian children. Data were drawn from wave 2 (2-3 years, n=4601) and wave 3 (4-5 years, n=4381) of the Longitudinal Study of Australian Children. The primary outcome was skipping breakfast. Child's and mother's BMI was assessed by trained professionals. Girls at 4-5 years were significantly more likely to skip breakfast compared with boys (56.9% versus 43.1%; P=0.031). In cross-sectional data analysis, obese boys at 2-3 years (odds ratio (OR) 2.38; P=0.039) and at 4-5 years (OR 2.32; P=0.046), and also obese girls at 4-5 years (OR 2.26; P=0.018), were more likely to skip breakfast. Skipping breakfast was positively associated with boys at 2-3 years (OR 2.04; P=0.042) whose mothers were overweight and with girls at 4-5 years (OR 2.60; P=0.001) whose mothers were obese. In longitudinal cross-lagged analysis, boys at 2-3 years whose mothers were obese were more likely to skip breakfast 2 years later at age 4-5 years (OR 2.36; P=0.045). Skipping breakfast was associated with higher BMI in children and mothers. Future interventions should target obese mothers to promote breakfast intake among children. The interventions may involve changes to dietary and lifestyle habits and provision of education on the benefits of breakfast intake.

    We examined baseline HIV-1 protease and reverse transcriptase sequences and HIV clinical parameters from 1,021 consecutive patients (814 male, 207 female) through the Royal Perth Hospital HIV service to investigate HIV-1 subtype diversity and local phylogenetic networks from 2000 to 2014. HIV-1 subtype B virus sequences were demonstrated in 619 (61%) of cases, with increasing non-B HIV-1 subtypes from 23.2% (2000-2003) to 48% (2008-2011) and 43% (2012-2014) (p 2: 135/211; 64% vs. 13/69; 19%; p = 0.001), including one cluster of 53 HIV-1 B subtype sequences that evolved from 2008 to 2014. Non-B subtype HIV-1 was associated with lower baseline CD4 T cell count (p = 0.005) but not plasma HIV-1 RNA levels (p = 0.31), suggesting relatively delayed diagnosis. Baseline viral load was strongly associated with calendar time [mean 18,620 copies/ml in 2000-2003; 75,858 copies/ml in 2012-2014 (p 2) in adjusted analyses (p = 0.03). This study identifies a number of temporal trends over the past 15 years, including an increasing prevalence of non-B subtype HIV-1 that highlights the growing influence of migration and travel on the Australian HIV-1 epidemic and the associated increased role of heterosexual HIV-1 transmission in this context. At the same time, these data indicate that local transmission within predominantly male networks remains a challenging issue for HIV-1 prevention.

    This study aimed to elucidate the illness representations of patients with traumatic injury and to examine what extent their illness representations change over time. Traumatic injury has attracted global concern because it is the major reason for death and disability in people under 45 years old. One model, the Common Sense Model of Illness Representation (CSMIR), has the potential to help individuals adjust to changes in health status such as traumatic injury. Longitudinal study design. This study was conducted using a and collected data prior to hospital discharge and at three and six months after hospital discharge. One individual question form and the Chinese Illness Perception Questionnaire Revised (IPQ-R) (Trauma) were used to collect demographic data, clinical data and illness representations. A total of 114 participants completed the survey three times. The overall response rate was 79.7%. Six subscales of the Chinese (Trauma): identity, emotional representations, consequences, controllability, illness coherence and causes of the Chinese IPQ-R (Trauma) changed significantly over time. Two subscales, Timeline (acute/chronic) and Timeline Cyclical, did not change significantly. Based on these findings, there may be a window of opportunity to provide appropriate interventions to individuals with traumatic injury at each time point. The results of this study have implications for nursing practice and further nursing research. Understanding illness representation in patients with traumatic injury may help nurses to provide anticipatory guidance and to design nursing interventions before and after hospital discharge, ultimately to improve health outcomes of those patients.

    Full Text Available Abstract Background Physical inactivity is increasing among adolescents in the U.S., especially among girls. Despite growing evidence that parents are an important influence on adolescent health, few longitudinal studies have explored the causal relationship between parental influence and physical activity. This study examines how the relationships between parental influences and adolescent physical activity differ by gender and tests whether these relationships are mediated by adolescents' self-esteem and depression. Methods Data are from the National Longitudinal Study of Adolescent Health. The sample includes 13,246 youth, grades 7 to 12, interviewed in 1995 and again 1 year later. Logit models were used to evaluate parental influences on achieving five or more bouts of moderate to vigorous physical activity per week [MVPA] and whether the relationship between parental influence and MVPA was mediated by adolescents' level of self-esteem and depression. Results Family cohesion, parent-child communication and parental engagement positively predicted MVPA for both genders one year later (odds ratios and 95% confidence intervals for females, 1.09 [1.05–1.12], 1.13 [1.07–1.19], 1.25 [1.17–1.33] and males, 1.08 [1.04–1.11], 1.14 [1.07–1.23], 1.23 [1.14–1.33], respectively; however, parental monitoring did not (odds ratio and confidence intervals for females and males, 1.02 [.97–1.07]. For both females and males, self-esteem mediated the relationship between parental influence and physical activity. Depressive symptoms were only a mediator among males. Females reported higher levels of parent-child communication and lower family cohesion compared with males. There were no gender differences in levels of parental monitoring and engagement. Females had significantly lower levels of self-esteem and higher levels of depressive symptoms than males. Conclusion Strategies to promote physical activity among adolescents should focus on

  13. Studies of the longitudinal instability with an electron beam

    International Nuclear Information System (INIS)

    1993-01-01

    Goals for our first-year period are as follows: To study the evolution of a small perturbation in the current pulse (introduced via the grid voltage on the electron gun) when the beam propagates through our 5-m long periodic solenoid channel. Specifically, to see if the perturbation is reflected from the rear end of the pulse. So far these objectives have been met without any delays. We were able to launch different perturbations on the beam resulting in either a slow space-charge wave or a fast wave or both waves. The relative strength of each wave was found to depend on the electron emission temperature of the cathode. The propagation of these waves on an initially rectangular longitudinal beam profile was measured with fast current monitors and the kinetic energy was measured with sensitive energy analyzers at various positions along the 5-m long solenoidal focusing channel. We have also begun to study the behavior of the waves when they reach the respective edge of the beam. But this work is still of a preliminary nature, and we need to refine the beam conditions and measurements in future studies to reach any firm conclusions. Preparations for the resistive-wall instability experiment are in progress

    Full Text Available This longitudinal case series study explores how students’ conceptions of ‘mental health nursing’ changed whilst on a three-year pre-registration Mental Health Nursing programme. The study was carried out in two university nursing schools in the South East of England and this paper reports a detailed analysis of 6 individual case studies. The researchers utilised Novak’s approach to concept mapping to elicit students’ personal knowledge structures, which were explored further using semi-structured individual qualitative interviews. The maps were analysed by looking at their gross morphology to interpret changes over time into types of learning achieved and the associated interview data were analysed using thematic content analysis. Results from analysis of the map structures suggest that whilst four of the selected students learned deeply, one participant learned superficially and one appeared not to learn at all. The associated interview data provides an interesting insight into the students’ reflective narratives on the process of learning. The findings also demonstrate further evidence of the practicability of using Novakian concept maps to self-prompt qualitative research interviews. Implications for the professional education of Mental Health Nurses are discussed.

    This paper reports on the main findings of a longitudinal study of the learning styles of one cohort of undergraduate pre-registration nursing students at an Irish university. The Honey and Mumford (2000a) Learning Styles Questionnaire was administered to a sample of students in their first (n=202) and final year of study (n=166), the final sample number (58) was based on matched pairs. The most common dominant learning style in first year was the dual learning category (35%) while a large proportion of the students (53%) in their final year had no dominant learning style. The preferred learning style of students in their first (69%) and final (57%) year was reflector. Learning styles were significantly different at the two time points and there was a significant relationship between some learning styles and students' age but not with academic achievement. Total scores of all learning styles showed significant improvements across the two time points of the study. An important implication for nurse education practice is the need for nurse educators to be aware of students' learning styles and in an attempt to maximise students' learning potential, utilise a range of teaching and learning methodologies and assessments that develop all learning styles.

    Past research suggests that adverse experiences at work (such as job stressors and precarious employment) are associated with thoughts about suicide, especially among males. A limitation of this research is that it is largely cross-sectional. Thus, it is unknown whether job stressors are a prior cause of thoughts about suicide. This study examined the baseline association between adverse experiences at work and thoughts about suicide at follow-up in a large nationally representative cohort of employed men. We used data from the Australian Longitudinal Study on Male Health (Ten to Men). The outcome was thoughts about suicide in the prior 12 months (reported in wave 2) and the key exposure variables were: high job demands, low job control, job insecurity, perceived unfairness of pay, occupational skill level, and employment arrangement (all reported in wave 1). We adjusted for possible confounders, including mental health and suicidal thoughts (wave 1). In a sample of 8379 and after adjustment, job insecurity (OR 1.35, 95% CI 1.13-1.61, P = 0.001), low job control (OR 1.19, 95% CI 1.06-1.33, P = 0.004), and employment on a casual or on a fixed term basis (OR 1.30, 95% 1.01-1.67, P = 0.041) were associated with a greater odds of thoughts about suicide at follow up. Results for all by job control were maintained after removing those who reported thoughts of suicide at baseline. This study suggests that experiences at work may be risk factors for thoughts about suicide among employed men. More research is needed to unpack the complex associations between, employment, and experiences of suicide.

    The aims of this study were to produce a population-based estimate of the prevalence of work-related exposure to formaldehyde, to identify the main circumstances of exposure and to describe the use of workplace control measures designed to decrease those exposures. The analysis used data from the Australian Workplace Exposures Study, a nationwide telephone survey, which investigated the current prevalence and exposure circumstances of work-related exposure to 38 known or suspected carcinogens, including formaldehyde, among Australian workers aged 18-65 years. Using the web-based tool OccIDEAS, semi-quantitative information was collected about exposures in the current job held by the respondent. Questions were addressed primarily at tasks undertaken rather than about self-reported exposures. Of the 4993 included respondents, 124 (2.5%) were identified as probably being exposed to formaldehyde in the course of their work [extrapolated to 2.6% of the Australian working population-265 000 (95% confidence interval 221 000-316 000) workers]. Most (87.1%) were male. About half worked in technical and trades occupations. In terms of industry, about half worked in the construction industry. The main circumstances of exposure were working with particle board or plywood typically through carpentry work, building maintenance, or sanding prior to painting; with the more common of other exposures circumstances being firefighters involved in fighting fires, fire overhaul, and clean-up or back-burning; and health workers using formaldehyde when sterilizing equipment or in a pathology laboratory setting. The use of control measures was inconsistent. Workers are exposed to formaldehyde in many different occupational circumstances. Information on the exposure circumstances can be used to support decisions on appropriate priorities for intervention and control of occupational exposure to formaldehyde, and estimates of burden of cancer arising from occupational exposure to formaldehyde

    Little is known about laxative use, the association of constipation with laxative use, risk factors for constipation and how each of these changes over time in the community-dwelling elderly. The aim was to explore the prevalence of laxative use and of self-reported constipation, and identify risk factors (including age) associated with constipation, in a cohort of community-dwelling elderly residents. Data from the Australian Longitudinal Study of Ageing (ALSA) was used to compare differences in constipation and laxative use in the community-dwelling elderly between 1992-1993 and 2003-2004. Relevant data was available for 239 ALSA participants. The prevalence of self-reported constipation increased from 14% in 1992-1993 to 21% in 2003-2004. There was a corresponding increase in the prevalence of laxative use from 6% to 15% over the same period. At both time points, females reported a higher prevalence of both constipation and laxative use however the female:male prevalence ratios decreased over time indicating higher increases in the prevalence of each among males. Persistent chronic constipation occurred in 9% of the cohort. The association between laxative use and self-reported constipation was poor and laxative use was associated with self-reported constipation in less than a third of cases. The prevalence of both constipation and laxative use increases with age in the elderly, and these increases are greater for males than for females. Discrepancies between self-reported constipation and laxative use may suggest sub-optimal management of constipation in the community-dwelling elderly and further work is needed to fully understand this.

    Much of the research into cyclist safety in Australia has focused on behaviour with less focus on the impact of the urban transport environment on cyclist safety. A greater understanding of the urban transport system and the improvements needed to create a safer cycling environment are essential if cyclists are to be safe and increased cycling participation targets are to be achieved. The proposed study will use existing cyclist crash data along with unique cyclist exposure data to develop road infrastructure prototypes that improve cyclists' safety and evaluate the effectiveness of these prototypes in a cycling simulator. This study will be conducted in two Australian cities namely Perth and Melbourne as both cities have policies that strongly advocate cycling. Two methods of data collection will be employed: (1) in-depth crash investigations of injured cyclists; and (2) video footage of cyclist exposure through a naturalistic cycling study of non-injured cyclists. The findings from these two methods will be used to develop new urban road design prototypes which will be tested with a sample of cyclists and motorists in safe environment namely, a cycling simulator and a driving simulator. By designing and evaluating safer environments for cyclists, this study will identify solutions that reduce the risk of road trauma and importantly, support this alternative mode of transport and thereby contribute to a reduction in traffic-related emissions and pollution and enhance sustainable economic and social connectivity.

    We study European options on the ratio of the stock price to its average and viceversa. Some of these options are traded in the Australian Stock Exchange since 1992, thus we call them Australian Asian options. For geometric averages, we obtain closed-form expressions for option prices. For arithmetic means, we use different approximations that produce very similar results.

    Factors associated with depression of medical students are poorly understood. The purpose of this study is to determine the prevalence of depression in medical students, its change during the course, if depression persists for affected students, what are the factors associated with depression and how these factors change over time. A prospective, longitudinal observational study was conducted at the Medical School of the University of Minho, Portugal, between academic years 2009-2010 to 2012-2013. We included students who maintained their participation by annually completing a questionnaire including Beck Depression Inventory (BDI). Anxiety and burnout were assessed using the State Trait Anxiety Inventory and Maslach Burnout Inventory. Surveys on socio-demographic variables were applied to evaluate potential predictors, personal and academic characteristics and perceived difficulties. ANOVA with multiple comparisons were used to compare means of BDI score. The medical students were organized into subgroups by K-means cluster analyses. ANOVA mixed-design repeated measurement was performed to assess a possible interaction between variables associated with depression. The response rate was 84, 92, 88 and 81% for academic years 2009-2010, 2010-2011,2011-2012 and 2012/2013, respectively. Two hundred thirty-eight medical students were evaluated longitudinally. For depression the prevalence ranged from 21.5 to 12.7% (academic years 2009/2010 and 2012/2013). BDI scores decreased during medical school. 19.7% of students recorded sustained high BDI over time. These students had high levels of trait-anxiety and choose medicine for anticipated income and prestige, reported more relationship issues, cynicism, and decreased satisfaction with social activities. Students with high BDI scores at initial evaluation with low levels of trait-anxiety and a primary interest in medicine as a career tended to improve their mood and reported reduced burnout, low perceived learning problems

    Resolving the theoretical controversy on the labeling of an increasing number of excessive behaviors as behavioral addictions may also be facilitated by more empirical data on these behavioral problems. For instance, an essential issue to the classification of psychiatric disorders is information on their natural course. However, longitudinal research on the chronic vs. episodic nature of behavioral addictions is scarce. The aim of the present study, therefore, was to provide data on prevalence, substance use comorbidity, and five-year trajectories of six excessive behaviors-namely exercising, sexual behavior, shopping, online chatting, video gaming, and eating. Analyses were based on the data of the Quinte Longitudinal Study, where a cohort of 4,121 adults from Ontario, Canada was followed for 5 years (2006 to 2011). The response rate was 21.3%, while retention rate was 93.9%. To assess the occurrence of each problem behavior, a single self-diagnostic question asked people whether their over-involvement in the behavior had caused significant problems for them in the past 12 months. To assess the severity of each problem behavior reported, the Behavioral Addiction Measure was administered. A mixed design ANOVA was used to investigate symptom trajectories over time for each problem behavior and whether these symptom trajectories varied as a function of sex. The large majority of people reported having problematic over-involvement for just one of these behaviors and just in a single time period. A main effect of time was found for each problem behavior, indicating a moderately strong decrease in symptom severity across time. The time x sex interaction was insignificant in each model indicating that the decreasing trend is similar for males and females. The data also showed that help seeking was very low in the case of excessive sexual behavior, shopping, online chatting, and video gaming but substantially more prevalent in the case of excessive eating and

    The objective of this study was to explore how maternal mood during pregnancy, i.e., general anxiety, pregnancy-specific anxiety, and depression predicted parenting stress 3 months after giving birth, thereby shaping the child's early postnatal environmental circumstances. To this end, data were used from 1073 women participating in the Dutch longitudinal cohort Generations 2 , which studies first-time pregnant mothers during pregnancy and across the transition to parenthood. Women filled out the State Trait Anxiety Inventory (STAI), Pregnancy-Related Anxiety Questionnaire-revised (PRAQ-R), and Beck Depression Index (BDI) three times during pregnancy: at 12, 22, and 32 weeks gestational age. Three months postpartum, a parenting stress questionnaire was filled out yielding seven different parenting constructs. Latent scores were computed for each of the repeatedly measured maternal mood variables with Mplus and parenting stress constructs were simultaneously regressed on these latent scores. Results showed that trait anxiety and pregnancy-specific anxiety were uniquely related to almost all parenting stress constructs, taking depression into account. Early prevention and intervention to reduce maternal anxiety in pregnancy could hold the key for a more advantageous trajectory of early postnatal parenting.

    Some students may be diagnosed with a learning disability in mathematics or dyscalculia, whereas other students may demonstrate below-grade-level mathematics performance without a disability diagnosis. In the literature, researchers often identify students in both groups as experiencing math difficulty. To understand the performance of students with math difficulty, we examined 35 studies that reported longitudinal results of mathematics achievement (i.e., mathematics performance measured across at least a 12-month span). Our primary goal was to conduct a systematic review of these studies and to understand whether the growth of students with math difficulty was comparable or stagnant when compared with that of students without math difficulty. We also analyzed whether identification of math difficulty was predictive of mathematics achievement in later grades and whether a diagnosis of math difficulty was stable across grade levels. Results indicate that students with math difficulty demonstrate growth on mathematics measures, but this growth still leads to lower performance than that of students without math difficulty. Identification of math difficulty is strongly related to math performance in subsequent grades, and this diagnosis is often stable. Collectively, this literature indicates that students with math difficulty continue to struggle with mathematics in later grades.

    Full Text Available BACKGROUND Valproate shows the most promising efficiency in treating mood as well as anxiety disorders; however, thrombocytopenia is one of the most common side effects associated with it. The perceived novelty and under recognition of the platelet lowering effects of valproate is illustrated by various case reports of thrombocytopenia associated with valproate in psychiatric populations. AIMS Present study aims is to investigate the relationship between platelet count & VPA therapy, age, and duration of medication. SETTINGS AND DESIGN It was a longitudinal observational study conducted at Department of Psychiatry, Pt. JNM Medical College, Raipur. METHODS AND MATERIAL The sample consisted of patients of either sex, aged between 18 to 65 years who were prescribed valproate therapy by the treating doctor. Patients were evaluated at baseline, at every month up to three months and at six months. The platelet counts were determined using an automatic haematology analyser. STATISTICAL ANALYSIS Correlation statistics were used to analyse the collected data. CONCLUSION Most of the time thrombocytopenia is mild and transient which resolves spontaneously. Regular monitoring of platelet level is required in the high risk groups.

    Full Text Available The Tea Party movement, which rose to prominence in the United States after the election of President Barack Obama, provides an ideal context in which to examine the roles of racial concerns and ideology in politics. A three-wave longitudinal study tracked changes in White Americans' self-identification with the Tea Party, racial concerns (prejudice and racial identification, and ideologies (libertarianism and social conservatism over nine months. Latent Growth Modeling (LGM was used to evaluate potential causal relationships between Tea Party identification and these factors. Across time points, racial prejudice was indirectly associated with movement identification through Whites' assertions of national decline. Although initial levels of White identity did not predict change in Tea Party identification, initial levels of Tea Party identification predicted increases in White identity over the study period. Across the three assessments, support for the Tea Party fell among libertarians, but rose among social conservatives. Results are discussed in terms of legitimation theories of prejudice, the "racializing" power of political judgments, and the ideological dynamics of the Tea Party.

    Our objective was to identify major dietary sources of whole grains and to describe the construction of a database of whole grain content of foods. Dietary information was collected with 7-d food records from men and women in the Baltimore Longitudinal Study of Aging, mean age 62.1 +/- 16.0 years, who participated in the dietary assessment portion of the study (n = 1516), and estimates of whole grain intake were obtained from a newly developed database. The Pyramid Servings database and 1994-1996 Continuing Survey of Food Intakes by Individuals (CSFII) recipe ingredients database were then used to calculate both servings and gram weights of whole grain intakes. Mean intakes of whole grains, refined grains, and total grains, as well as frequency of intake for major whole grain food groups and whole grain content for each group, were calculated. Top contributors of whole grains were ready-to-eat breakfast cereals (made with whole grain as well as bran), hot breakfast cereals (made with whole grain), multi-grain bread, and whole wheat bread. While more research is needed to better understand the benefits of whole grains, the development of research tools, including databases to accurately assess whole grain intake, is a critical step in completing such research.

    Service-learning (SL) is commonly used in Occupational Therapy (OT) programs worldwide as a community placement educational strategy. However, most SL models are not clearly defined in terms of both methodology and learning outcomes. This longitudinal study explores a structured model of Service-Learning (Interpersonal Social Responsibility-Service Learning: ISR-SL) aimed towards the development of professional identity among OT students. Based on OT students experiences from the end of the course through later stages as mature students and professionals. A qualitative research design was used to explore the perceptions and experiences of 150 first, second, and third-year OT students and graduates who have participated in ISR-SL during their first academic year. Our findings suggest that the structured, long-term relationship with a person with a disability in the natural environment, which is the core of the ISR-SL, allowed students to develop a professional identity based on seeing the person as a whole and recognizing his/her centrality in the therapeutic relationship. This study suggests ISR-SL as future direction or next step for implementing SL in OT and other healthcare disciplines programs.

    Background The Australian Defence Force (ADF) Mental Health Prevalence and Wellbeing Study (MHPWS) is the first study of mental disorder prevalence in an entire military population. Objective The MHPWS aims to establish mental disorder prevalence, refine current ADF mental health screening methods, and identify specific occupational factors that influence mental health. This paper describes the design, sampling strategies, and methodology used in this study. Method At Phase 1, approximately half of all regular Navy, Army, and Air Force personnel (n=24,481) completed self-report questionnaires. At Phase 2, a stratified sub-sample (n=1,798) completed a structured diagnostic interview to detect mental disorder. Based on data from non-responders, data were weighted to represent the entire ADF population (n=50,049). Results One in five ADF members met criteria for a 12-month mental disorder (22%). The most common disorder category was anxiety disorders (14.8%), followed by affective (9.5%) and alcohol disorders (5.2%). At risk ADF sub-groups were Army personnel, and those in the lower ranks. Deployment status did not have an impact on mental disorder rates. Conclusion This study has important implications for mental health service delivery for Australian and international military personnel as well as contemporary veterans. PMID:25206944

    Full Text Available This study aims to explore the narrative identity of a politician-turned-doctoral student at an Australian university with a particular focus on his academic and social encounters based on his English resources and experiences of learning and living in Australia. This case study is unique in the way that very few Thai politicians would end their political career and join in an academic community because of different philosophies underpinning these political and educational agendas. Drawing upon a narrative inquiry, the 60-year-old former Thai politician who decided to undertake a PhD in Engineering (Water Resources Management found his academic experience positively challenging as he had to familiarize himself with Australian academic discourse such as conducting research, writing his thesis, and taking part in class discussion. Being a competent user of English, he enjoyed living in a multicultural and multilingual society in Australia. This study offers an optimistic outlook at career change through a lens of a politician who became a doctoral student and serves as an example for adults who are transiting their midlife career path and considering stepping out of their comfort zones to venture into something new and exciting. This study hopes to shed new light and hopes on adult education in an era of aging society.

A pesquisa internacional aponta para a existência de alguns preditores desta perturbação da aprendizagem, permitindo uma intervenção atempada e preventiva. No entanto, as diferenças relativas ao código ortográfico do Português Europeu não nos permitem tirar ilações de estudos realizados noutros contextos linguísticos. Com este problema em mente, desenvolvemos um estudo longitudinal que pretende destacar os preditores da dislexia em crianças portuguesas. A investigação seguiu um plano longitudinal ao longo de três anos e os resultados obtidos junto de uma amostra de 200 crianças permitem identificar a existência de poder preditivo em duas variáveis: no conhecimento que a criança tem do nome das letras e no seu desempenho em tarefas de fluência verbal, mostrando a influência que os fatores relativos às dificuldades na aquisição do princípio alfabético e no acesso ao léxico terão na manifestação posterior de problemas na aquisição da leitura.

    The Craniofacial Biology Research Group in the School of Dentistry at The University of Adelaide is entering an exciting new phase of its studies of dental development and oral health in twins and their families. Studies of the teeth and faces of Australian twins have been continuing for nearly 30 years, with three major cohorts of twins recruited over that time, and currently we are working with twins aged 2 years old to adults. Cross-sectional data and records relating to teeth and faces of twins are available for around 300 pairs of teenage twins, as well as longitudinal data for 300 pairs of twins examined at three different stages of development, once with primary teeth, once at the mixed dentition stage, and then again when the permanent teeth had emerged. The third cohort of twins comprises over 600 pairs of twins recruited at around birth, together with other family members. The emphasis in this third group of twins has been to record the timing of emergence of the primary teeth and also to sample saliva and dental plaque to establish the timing of colonization of decay-forming bacteria in the mouth. Analyses have confirmed that genetic factors strongly influence variation in timing of primary tooth emergence. The research team is now beginning to carry out clinical examinations of the twins to see whether those who become colonized earlier with decay-forming bacteria develop dental decay at an earlier age. By making comparisons within and between monozygotic (MZ) and dizygotic (DZ) twin pairs and applying modern molecular approaches, we are now teasing out how genetic, epigenetic, and environmental factors interact to influence dental development and also oral health.

    Despite the multitude of longitudinal neuroimaging studies that have been published, a basic question on the progressive brain loss in schizophrenia remains unaddressed: Does it reflect accelerated aging of the brain, or is it caused by a fundamentally different process? The authors used support vector regression, a supervised machine learning technique, to address this question. In a longitudinal sample of 341 schizophrenia patients and 386 healthy subjects with one or more structural MRI scans (1,197 in total), machine learning algorithms were used to build models to predict the age of the brain and the presence of schizophrenia ("schizophrenia score"), based on the gray matter density maps. Age at baseline ranged from 16 to 67 years, and follow-up scans were acquired between 1 and 13 years after the baseline scan. Differences between brain age and chronological age ("brain age gap") and between schizophrenia score and healthy reference score ("schizophrenia gap") were calculated. Accelerated brain aging was calculated from changes in brain age gap between two consecutive measurements. The age prediction model was validated in an independent sample. In schizophrenia patients, brain age was significantly greater than chronological age at baseline (+3.36 years) and progressively increased during follow-up (+1.24 years in addition to the baseline gap). The acceleration of brain aging was not constant: it decreased from 2.5 years/year just after illness onset to about the normal rate (1 year/year) approximately 5 years after illness onset. The schizophrenia gap also increased during follow-up, but more pronounced variability in brain abnormalities at follow-up rendered this increase nonsignificant. The progressive brain loss in schizophrenia appears to reflect two different processes: one relatively homogeneous, reflecting accelerated aging of the brain and related to various measures of outcome, and a more variable one, possibly reflecting individual variation and

    We describe the implementation of cognitive measures within the Canadian Longitudinal Study on Aging (CLSA), a nationwide, epidemiological study of aging, and relate CLSA Tracking cohort data (n over 20,000) to previous studies using these measures. CLSA participants (aged 45-85, n over 50,000) provided demographic, social, physical/clinical, psychological, economic, and health service utilization information relevant to health and aging through telephone interviews (Tracking cohort, n over 20,000) or in-person (i.e. Comprehensive cohort, n over 30,000) in both official languages (i.e. English, French). Cognitive measures included: the Rey Auditory Verbal Learning Test (RAVLT) - Trial 1 and five-minute delayed recall; Animal Fluency (AF), the Mental Alternation Test (MAT) (both cohorts); Controlled Oral Word Association Test, Stroop Test, Prospective Memory Test, and Choice reaction times (Comprehensive Cohort). Performance on the RAVLT Trial 1 and AF were very similar to comparable groups studied previously; CLSA sample sizes were far larger. Within the CLSA Tracking cohort, main effects of age and language were observed for all cognitive measures except RAVLT delayed recall. Interaction effects (language × age) were observed for AF. This preliminary examination of the CLSA Tracking cognitive measures lends support to their use in large studies of aging. The CLSA has the potential to provide the 'best' comparison data for adult Canadians generated to date and may also be applicable more broadly. Future studies examining relations among the psychological, biological, health, lifestyle, and social measures within the CLSA will make unique contributions to understanding aging.

    ISSUED ADDRESSED: The increase trend in the prevalence of dental caries in Australian children is a concern to public health professionals. Attitudes, behaviours and lifestyle patterns established in childhood are often carried throughout adult life. The objective of the study was to estimate the proportion of Perth metropolitan year two public primary school children drinking tap water at home, school and play. It also aimed to explore knowledge and attitudes that children and parents have towards drinking tap water, bottled water, fruit juices and soft drinks. Nine Western Australian government primary schools were recruited. A facilitator-led questionnaire was administered to year two primary school students and a matched parent self-administered questionnaire was also completed. Forty-two per cent of the children in our study reported if thirsty they drank tap (fluoridated) water at home whereas parents stated 60% of children drank tap water at home. The type of drink appeared to vary with time of day/activity while overall water was most frequently drunk; a higher proportion of milk was drunk at breakfast, whereas soft drinks were drunk in a greater proportion while watching television. This study found the vast majority of year two children in metropolitan Perth public primary schools are drinking tap water.

    Given the scarcity of comprehensive nutritional data for Australia's >400 commercially produced seafood species a pilot study was undertaken to collect and analyse 22 species of wild and aquaculture seafood in order to develop a model for future comprehensive surveys. The species analysed were: Atlantic salmon, Australian sardine, prawn (six species), barramundi, abalone (three species), blue sprat, burrowing blackfish, gummy shark, oyster (four species), ocean trout and yellowtail kingfish. The analyses undertaken in this pilot study were: moisture, protein, total fat, cholesterol, fatty acids, vitamin C, vitamins A and D, and 21 mineral elements (including total mercury and methyl mercury). The data reported here are for vitamin D and mercury only. Comprehensive data have already been published elsewhere. Issues identified that should be addressed prior to undertaking a more extensive and representative study of the remaining major edible commercial Australian seafood species include: choice of samples and nutrients for analysis, facilities for sample handling and storage, data management and scrutiny, and laboratory quality control.

    This study examined the longitudinal and cross-sectional effects of both psychosocial stress and depressive symptoms on insulin resistance and percentage body fat in a cohort of healthy Australian children, following them from childhood into adolescence. Participants were 791 healthy, initially Grade 2 children (7-8 years; 394 girls), selected from the general community. Psychosocial stress was assessed using the Children's Stress Questionnaire, while depressive symptoms were assessed using the Children's Depression Inventory. Fasting blood samples for serum insulin and plasma glucose were collected to calculate the homeostasis model assessment-insulin resistance (HOMA-IR). Other measurements were height, weight, percentage body fat (dual energy x-ray absorptiometry), physical activity (pedometers), and pubertal maturation (Tanner score). Boys who reported more symptoms of depression had higher insulin resistance, irrespective of adiposity (p = .016); and longitudinally, we found a trend for boys who developed more depressive symptoms to develop higher insulin resistance (p = .073). These findings did not extend to girls. Furthermore, boys and girls with higher depressive symptoms had a higher percentage of body fat (p = .011 and .020, respectively); and longitudinally, boys whose depressive symptoms increased became fatter (p = .046). Our data provide evidence that early symptoms of depression increase insulin resistance, independent of adiposity. Our evidence that early symptoms of depression may lead to overweight, and obesity provides further reason to suggest that early attention to children with depression, even in preclinical stages, may reduce risk of chronic disease in later life.

    This paper analyzes the effects of dental conditions on social functioning by measuring the incidence of work loss days associated with dental problems and treatments in 1 year. A longitudinal study of 1992 employed adults in the Hartford, Conn. area was conducted. Participants were interviewed at baseline to collect data on sociodemographic, health care and health status factors and were followed for 1 year to assess the incidence of dental work loss days. The results showed that 26.4% of the sample reported an episode of dentally-related work, with a mean of 1.26 hours per person per year. The most important predictors of having work loss were high number of dental visits, previously having an episode of work loss, being young and being in the higher social classes. The most important variables explaining total hours of work loss were treatment severity, previous work loss, low income and being non-white. While work loss rates varied by some important treatment and sociodemographic factors, more sensitive outcome indicators are needed to detect individual differences in the effects of dental conditions on social functioning. Yet, the results do suggest that work loss days may be a useful population statistic in measuring oral health status because of the high prevalence of dental disease.

    Full Text Available Abstract Background The influence of serum leptin levels on nutritional status and survival in chronic hemodialysis patients remained to be elucidated. We conducted a prospective longitudinal study of leptin levels and nutritional parameters to determine whether changes of serum leptin levels modify nutritional status and survival in a cohort of prevalent hemodialysis patients. Methods Leptin, dietary energy and protein intake, biochemical markers of nutrition and body composition (anthropometry and bioimpedance analysis were measured at baseline and at 6, 12, 18 and 24 months following enrollment, in 101 prevalent hemodialysis patients (37% women with a mean age of 64.6 ± 11.5 years. Observation of this cohort was continued over 2 additional years. Changes in repeated measures were evaluated, with adjustment for baseline differences in demographic and clinical parameters. Results Significant reduction of leptin levels with time were observed (linear estimate: -2.5010 ± 0.57 ng/ml/2y; p Conclusions Thus leptin levels reflect fat mass depots, rather than independently contributing to uremic anorexia or modifying nutritional status and/or survival in chronic hemodialysis patients. The importance of such information is high if leptin is contemplated as a potential therapeutic target in hemodialysis patients.

    To establish the mental health needs of homeless children and families before and after rehousing. Cross sectional, longitudinal study. City of Birmingham. 58 rehoused families with 103 children aged 2-16 years and 21 comparison families of low socioeconomic status in stable housing, with 54 children. Children's mental health problems and level of communication; mothers' mental health problems and social support one year after rehousing. Mental health problems remained significantly higher in rehoused mothers and their children than in the comparison group (mothers 26% v 5%, P = 0.04; children 39% v 11%, P = 0.0003). Homeless mothers continued to have significantly less social support at follow up. Mothers with a history of abuse and poor social integration were more likely to have children with persistent mental health problems. Homeless families have a high level of complex needs that cannot be met by conventional health services and arrangements. Local strategies for rapid rehousing into permanent accommodation, effective social support and health care for parents and children, and protection from violence and intimidation should be developed and implemented.

    Increased use of contraceptives in Malawi has not translated into a commensurate reduction in fertility, but the reason is unknown. Insight into contraceptive switching and discontinuation may shed light on this conundrum and on whether the commonly used modern contraceptive prevalence rate (mCPR) is the best indicator of family planning program performance. A one-year prospective longitudinal data set was created from patient-held family planning cards of 4,678 reproductive-age women living in a demographic surveillance site in rural northern Malawi. Contraceptive service data recorded on the women's cards by providers were linked to their socioeconomic, demographic and health data. Contraceptive point prevalence estimates calculated from these data were compared with mCPR estimates from cross-sectional surveys. Survival analyses examined contraceptive adherence. The contraceptive point prevalence of 35% was slightly lower than comparable cross-sectional estimates of mCPR. Only 51% of users of the injectable-the most widely used modern method-received their first reinjection on time, and just 15% adhered to the method for 12 months. Although various study variables were associated with contraceptive use, none were associated with adherence. Gaps in and discontinuation of use of the injectable may play a role in the discrepancy between mCPR and fertility. Interventions to help women adhere to injectable use and to promote long-acting methods should be strengthened.

    This study represents the first longitudinal effort to use a spiritual stress and coping model to predict adults' psychosocial adjustment following divorce. A community sample of 89 participants completed measures at the time of their divorce and 1 year later. Though the sample endorsed slightly lower levels of religiosity than the general U.S. population, most reported spiritual appraisals and positive and negative religious coping tied to divorce. Hierarchical regression analyses controlling general religiousness and nonreligious forms of coping indicated that (a) appraising divorce as a sacred loss or desecration at the time it occurred predicted more depressive symptoms and dysfunctional conflict tactics with the ex-spouse 1 year later; (b) positive religious coping reported about the year following divorce predicted greater posttraumatic growth 1 year after divorce; and (c) negative religious coping reported about the year following divorce predicted more depressive symptoms 1 year after the divorce. Bootstrapping mediation analyses indicated that negative religious coping fully mediated links between appraising the divorce as a sacred loss or desecration at the time it occurred and depressive symptoms 1 year later. In addition, moderation analyses revealed that negative religious coping is more strongly associated with depressive symptoms among those who form high versus low appraisals of their divorce as a sacred loss or desecration. These findings are relevant to divorce education and intervention provided by professionals in legal, family, mental health, and clerical roles. Implications are discussed for clinical and counseling psychology and religious communities.

    Full Text Available Background: No study has evaluated the effects of executive function on follow-up sedentary behavior, which was this study’s purpose. Methods: A longitudinal design was employed among 18 young adult college students (Mage = 23.7 years; 88.9% female. Accelerometer-determined sedentary behavior and physical activity, along with executive function, were assessed at baseline. Approximately 8 weeks later, re-assessment of accelerometer-determined sedentary behavior and physical activity occurred. Executive function was assessed using the Parametric Go/No-Go (PGNG computer task. From this, 2 primary executive function outcome parameters were evaluated, including the Simple Rule and Repeating Rule. Results: After adjusting for baseline sedentary behavior, age, gender, body mass index and baseline moderate-to-vigorous physical activity (MVPA, for every 25% increase in the number of correctly identified targets for the Repeating rule at the baseline assessment, participants engaged in 91.8 fewer minutes of sedentary behavior at the follow-up assessment (β = -91.8; 95% CI: -173.5, -10.0; P = 0.03. Results were unchanged when also adjusting for total baseline or follow-up physical activity. Conclusion: Greater executive function is associated with less follow-up sedentary behavior.

    We undertook a longitudinal qualitative study involving of 20 patients from Scotland who had type 2 diabetes. We looked at their perceptions and understandings of why they had developed diabetes and how, and why, their causation accounts had changed or remained stable over time. Respondents, all of whom were white, were interviewed four times over a 4-year period (at baseline, 6, 12 and 48 months). Their causation accounts often shifted, sometimes subtly, sometimes radically, over the 4 years. The experiential dimensions of living with, observing, and managing their disease over time were central to understanding the continuities and changes we observed. We also highlight how, through a process of removing, adding and/or de-emphasising explanatory factors, causation accounts could be used as "resources" to justify or enable present treatment choices. We use our work to support critiques of social cognition theories, with their emphasis upon beliefs being antecedent to behaviours. We also provide reflections upon the implications of our findings for qualitative research designs and sampling strategies.

    Because national surveys of people living with psychotic disorders tend to exclude people with low English proficiency (LEP), little is known of their economic and social functioning. Culturally influenced explanatory models may result in delayed presentation and poorer functioning. The study aimed to compare the functioning of LEP Vietnamese-Australian and Australian-born patients with psychosis and to investigate the Vietnamese-Australians' pathways to care. In all, 19 LEP Vietnamese-Australians, previously excluded from the Australian Survey of High Impact Psychosis (SHIP), were matched with 15 Australian-born controls, and interviewed by a Vietnamese bilingual mental health professional using the SHIP Interview Schedule. The Vietnamese-Australian patients were significantly more likely to live with family, rate spirituality as important and participate in community rehabilitation programs. Their work, social and independent functioning, was better than the controls. The groups did not differ in mental health services received and satisfaction with services. Although half of Vietnamese-Australians attributed mental illness to supernatural, among other causes, none had consulted traditional healers. Despite LEP, Vietnamese-Australians with psychosis showed comparable or better functioning than Australian-born patients. Further investigation is recommended into LEP patients' clinical and social recovery and the role of language communities' support networks. © The Author(s) 2014.

  16. Do mathematics textbooks cultivate shallow teaching? Applying the TIMSS Video Study criteria to Australian eighth-grade mathematics textbooks

    Science.gov (United States)

    Vincent, Jill; Stacey, Kaye

    2008-04-01

    Australian eighth-grade mathematics lessons were shown by the 1999 TIMSS Video Study to use a high proportion of problems of low procedural complexity, with considerable repetition, and an absence of deductive reasoning. Using definitions from the Video Study, this study re-investigated this `shallow teaching syndrome' by examining the problems on three topics in nine eighth-grade textbooks from four Australian states for procedural complexity, type of solving processes, degree of repetition, proportion of `application' problems and proportion of problems requiring deductive reasoning. Overall, there was broad similarity between the characteristics of problems in the textbooks and in the Australian Video Study lessons. There were, however, considerable differences between textbooks and between topics within textbooks. In some books, including the best-selling textbooks in several states, the balance is too far towards repetitive problems of low procedural complexity.

    Electrophysical agents (EPAs) are a core part of physiotherapy practice and entry level education. With the increase in the number of EPAs over time, their availability and use in contemporary physiotherapy practice is an important consideration when determining entry level curricula. Thus, the aim of the study was to ascertain the current availability and usage of EPAs in Australian physiotherapy practice. A purpose-designed questionnaire was mailed to all registered physiotherapists in Australia. A response rate of 27% was obtained (n=3,538). Nonresponder analyses indicated that the results were representative of the total population of Australian physiotherapists. Over 70% of respondents had access to ultrasound, cold packs/ice, heat packs, electrical stimulation for sensory stimulation, and interferential therapy. Two main groups of EPAs were used relatively frequently. The first group was used daily or monthly by 60% of respondents (ultrasound, hot packs, and cold packs/ice), and a second group (electromyographic and pressure biofeedback, interferential therapy, and electrical stimulation for sensory stimulation) was used on a daily or monthly basis by between 30% and 45% of the sample. A group of EPAs, including ultraviolet light, microwave, and shortwave diathermy, was not used by over 90% of the sample. The study has provided contemporary national data on EPA availability and use in Australia.

    Adult education institutions have been identified as potential settings to improve health literacy and address the health inequalities that stem from limited health literacy. However, few health literacy interventions have been tested in this setting. Feasibility study for an RCT of the UK Skilled for Health Program adapted for implementation in Australian adult education settings. Implementation at two sites with mixed methods evaluation to examine feasibility, test for change in participants' health literacy and pilot test health literacy measures. Twenty-two socially disadvantaged adults with low literacy participated in the program and received 80-90 hours of health literacy instruction. The program received institutional support from Australia's largest provider of vocational education and training and was feasible to implement (100 % participation; >90 % completion; high teacher satisfaction). Quantitative results showed improvements in participants' health literacy skills and confidence, with no change on a generic measure of health literacy. Qualitative analysis identified positive student and teacher engagement with course content and self-reported improvements in health knowledge, attitudes, and communication with healthcare professionals. Positive feasibility results support a larger RCT of the health literacy program. However, there is a need to identify better, multi-dimensional measures of health literacy in order to be able to quantify change in a larger trial. This feasibility study represents the first step in providing the high quality evidence needed to understand the way in which health literacy can be improved and health inequalities reduced through Australian adult education programs.

    The increased prevalence of malocclusions represents a secular trend attributed to the interaction of genetic and environmental factors. The analysis of factors related to the causes of these changes is essential for planning public health policies aimed at preventing and clinically intercepting malocclusion. This study investigated the sucking habits, nocturnal mouth breathing, as well as the relation of these factors with malocclusion. This is a longitudinal study in which 80 mother-child pairs were monitored from the beginning of pregnancy to the 30th month after childbirth. Home visits for interviews with the mothers were made on the 12th, 18th and 30th months of age. Finger sucking, pacifier sucking, bottle feeding, breastfeeding and nocturnal mouth breathing, were the variables studies. On the 30th month, clinical examinations were performed for overjet, overbite and posterior crossbite. A previously calibrated single examiner (Kappa coefficient = 0.92) was responsible for all examinations. Data were analyzed using the chi-squared or Fisher's exact tests, at a significance level of 5%. Bottle feeding was the most prevalent habit at 12, 18 and 30 months (87.5%; 90% and 96.25%, respectively). Breastfeeding was 40%, 25% and 12.50% at 12, 18 and 30 months, respectively. Nearly 70% of the children in this study had some sort of malocclusion. Pacifier sucking habit at 12, 18 and 30 months of age was associated with overjet and open bite; and at 30 months, an association with overbite was also observed. Finger sucking habit and breastfeeding at 12, 18 and 30 months were also associated with overjet and open bite. The posterior crossbite was associated with bottle feeding at 12 and 30 months, and nocturnal mouth breathers at 12 and 18 months. Sucking habits, low rates of breastfeeding, and nocturnal mouth breathing were risk factors for malocclusion.

    Longitudinal studies allow us to identify, which specific maths skills are weak in young children, and whether there is a continuing weakness in these areas throughout their school years. This 2-year study investigated whether certain socio-demographic variables affect early mathematical competency in children aged 5-7 years. A randomly selected sample of 127 students (64 female; 63 male) participated. At the start of the study, the students were approximately 5 years old (M= 5.2; SD= 0.28; range = 4.5-5.8). The students were assessed using the Early Numeracy Test and then allocated to a high (n= 26), middle (n= 76), or low (n= 25) achievers group. The same children were assessed again with the Early Numeracy Test at 6 and 7 years old, respectively. Eight socio-demographic characteristics were also evaluated: family model, education of the parent(s), job of the parent(s), number of family members, birth order, number of computers at home, frequency of teacher visits, and hours watching television. Early Numeracy Test scores were more consistent for the high-achievers group than for the low-achievers group. Approximately 5.5% of low achievers obtained low scores throughout the study. A link between specific socio-demographic characteristics and early achievement in mathematics was only found for number of computers at home. The level of mathematical ability among students aged 5-7 years remains relatively stable regardless of the initial level of achievement. However, early screening for mathematics learning disabilities could be useful in helping low-achieving students overcome learning obstacles. ©2011 The British Psychological Society.

    Full Text Available Abstract Background Indigenous Australians have an incidence of end stage kidney disease 8-10 times higher than non-Indigenous Australians. The majority of research studies concerning Indigenous Australians have been performed in rural or remote regions, whilst the majority of Indigenous Australians actually live in urban settings. We studied prevalence and factors associated with markers of kidney disease in an urban Indigenous Australian cohort, and compared results with those for the general Australian population. Methods 860 Indigenous adult participants of the Darwin Region Urban Indigenous Diabetes (DRUID Study were assessed for albuminuria (urine albumin-creatinine ratio≥2.5 mg/mmol males, ≥3.5 mg/mmol females and low eGFR (estimated glomular filtration rate 2. Associations between risk factors and kidney disease markers were explored. Comparison was made with the AusDiab cohort (n = 8,936 aged 25-64 years, representative of the general Australian adult population. Results A high prevalence of albuminuria (14.8% was found in DRUID, whilst prevalence of low eGFR was 2.4%. Older age, higher HbA1c, hypertension, higher C-reactive protein and current smoking were independently associated with albuminuria on multiple regression. Low eGFR was independently associated with older age, hypertension, albuminuria and higher triglycerides. Compared to AusDiab participants, DRUID participants had a 3-fold higher adjusted risk of albuminuria but not of low eGFR. Conclusions Given the significant excess of ESKD observed in Indigenous versus non-Indigenous Australians, these findings could suggest either: albuminuria may be a better prognostic marker of kidney disease than low eGFR; that eGFR equations may be inaccurate in the Indigenous population; a less marked differential between Indigenous and non-Indigenous Australians for ESKD rates in urban compared to remote regions; or that differences in the pathophysiology of chronic kidney disease exist

    Full Text Available Methicillin-resistant Staphylococcus pseudintermedius (MRSP is an emerging pathogen in dogs and has been found in Europe, Asia and North America. To date most studies are one-point prevalence studies and therefore little is known about the dynamics of MRSP in dogs and their surrounding. In this longitudinal study MRSP colonization in dogs and the transmission of MRSP to humans, contact animals and the environment was investigated. Sixteen dogs with a recent clinical MRSP infection were included. The index dogs, contact animals, owners and environments were sampled once a month for six months. Samples taken from the nose, perineum and infection site (if present of the index cases and contact animals, and the nares of the owners were cultured using pre-enrichment. Index cases were found positive for prolonged periods of time, in two cases during all six samplings. In five of the 12 households that were sampled during six months, the index case was intermittently found MRSP-positive. Contact animals and the environment were also found MRSP-positive, most often in combination with a MRSP-positive index dog. In four households positive environmental samples were found while no animals or humans were MRSP-positive, indicating survival of MRSP in the environment for prolonged periods of time. Genotyping revealed that generally similar or indistinguishable MRSP isolates were found in patients, contact animals and environmental samples within the same household. Within two households, however, genetically distinct MRSP isolates were found. These results show that veterinarians should stay alert with (former MRSP patients, even after repeated MRSP-negative cultures or after the disappearance of the clinical infection. There is a considerable risk of transmission of MRSP to animals in close contact with MRSP patients. Humans were rarely MRSP-positive and never tested MRSP-positive more than once suggesting occasional contamination or rapid elimination of

    External/intrusive violence at work can result in psychological distress and can be an important risk to employee health and safety. However, the vast majority of workplace violence studies have employed cross-sectional and correlational research, designed to examine immediate reactions after being assaulted at work. To explore whether exposure to robbery as a traumatic event may contribute to the onset of typical symptoms of psychological distress (anxiety depression, dysphoria and loss of confidence) and job dissatisfaction over time. We collected data by using a two-wave panel design, in which employees working the days of bank robberies, in an Italian bank, filled in a questionnaire between 48h and 1 week after the robbery (T1) and 2 months after the robbery (T2). We performed structural equation models to evaluate the fit of different models to our data. There were 513 participants at T1 (58% women) and 175 (34%) participants at T2 (62% women). There was a simultaneous association in which psychological distress leads to job dissatisfaction both following robbery and 2 months later. Our findings support a synchronous effects model and suggest that interventions after suffering physical assaults, apart from helping employees to recover their health, should consider restoring their trust and confidence in the organization. This study contributes to understanding the dynamic relationships between a robbery at work and its outcomes over time, by addressing several methodological deficiencies in previous longitudinal studies. © The Author 2015.

    Full Text Available Quality preschool programs that develop the whole child through age-appropriate socioemotional and cognitive skill-building hold promise for significantly improving child outcomes. However, preschool programs tend to either be teacher-led and didactic, or else to lack academic content. One preschool model that involves both child-directed, freely chosen activity and academic content is Montessori. Here we report a longitudinal study that took advantage of randomized lottery-based admission to two public Montessori magnet schools in a high-poverty American city. The final sample included 141 children, 70 in Montessori and 71 in other schools, most of whom were tested 4 times over 3 years, from the first semester to the end of preschool (ages 3–6, on a variety of cognitive and socio-emotional measures. Montessori preschool elevated children’s outcomes in several ways. Although not different at the first test point, over time the Montessori children fared better on measures of academic achievement, social understanding, and mastery orientation, and they also reported relatively more liking of scholastic tasks. They also scored higher on executive function when they were 4. In addition to elevating overall performance on these measures, Montessori preschool also equalized outcomes among subgroups that typically have unequal outcomes. First, the difference in academic achievement between lower income Montessori and higher income conventionally schooled children was smaller at each time point, and was not (statistically speaking significantly different at the end of the study. Second, defying the typical finding that executive function predicts academic achievement, in Montessori classrooms children with lower executive function scored as well on academic achievement as those with higher executive function. This suggests that Montessori preschool has potential to elevate and equalize important outcomes, and a larger study of public Montessori

    In this longitudinal population study, the aims were to study associations of mode of delivery with new onset of pelvic pain and changes in pelvic pain scores up to 7 to 18 months after childbirth. We included 20,248 participants enrolled in the Norwegian Mother and Child Cohort Study (1999-2008) without preexisting pelvic pain in pregnancy. Data were obtained by 4 self-administered questionnaires and linked to the Medical Birth Registry of Norway. A total of 4.5% of the women reported new onset of pelvic pain 0 to 3 months postpartum. Compared to unassisted vaginal delivery, operative vaginal delivery was associated with increased odds of pelvic pain (adjusted odds ratio [OR]: 1.30; 95% confidence interval [CI]: 1.06-1.59). Planned and emergency cesarean deliveries were associated with reduced odds of pelvic pain (adjusted OR: 0.48; 95% CI: 0.31-0.74 and adjusted OR: 0.65; 95% CI: 0.49-0.87, respectively). Planned cesarean delivery, young maternal age, and low Symptom Checklist-8 scores were associated with low pelvic pain scores after childbirth. A history of pain was the only factor associated with increased pelvic pain scores over time (P = 0.047). We conclude that new onset of pelvic pain after childbirth was not commonly reported, particularly following cesarean delivery. Overall, pelvic pain scores were rather low at all time points and women with a history of pain reported increased pelvic pain scores over time. Hence, clinicians should follow up women with pelvic pain after a difficult childbirth experience, particularly if they have a history of pain.

    Full Text Available Abstract Background The high frequency of premature death from cardiovascular disease in indigenous Australians is often attributed to the high prevalence of risk factors, especially type II diabetes mellitus (DM. We evaluated the relationship of ethnicity to atherosclerotic burden, as evidenced by carotid intima-media thickness (IMT, independent of risk factor status. Methods We studied 227 subjects (147 men; 50 ± 13 y: 119 indigenous subjects with (IDM, n = 54, and without DM (InDM, n = 65, 108 Caucasian subjects with (CDM, n = 52, and without DM (CnDM, n = 56. IMT was measured according to standard methods and compared with clinical data and cardiovascular risk factors. Results In subjects both with and without DM, IMT was significantly greater in indigenous subjects. There were no significant differences in gender, body mass index (BMI, systolic blood pressure (SBP, or diastolic blood pressure (DBP between any of the groups, and subjects with DM showed no difference in plasma HbA1c. Cardiovascular risk factors were significantly more prevalent in indigenous subjects. Nonetheless, ethnicity (β = -0.34; p Conclusion Ethnicity appears to be an independent correlate of preclinical cardiovascular disease, even after correction for the high prevalence of cardiovascular risk factors in indigenous Australians. Standard approaches to control currently known risk factors are vital to reduce the burden of cardiovascular disease, but in themselves may be insufficient to fully address the high prevalence in this population.

    Given time pressures on primary care physicians, utilising pharmacists for chronic disease management is of great interest. However, limited data are available on the current workflow in community pharmacies to guide these discussions. This study aimed to test the feasibility of collecting workflow data from Australian community pharmacies using the Work Observation Method By Activity Timing (WOMBAT) software and provide preliminary data on Australian pharmacy workflow. Data were collected from three pharmacies and four variables were recorded: what the pharmacist did, with whom, where and how. All tasks were timed and data were analysed to identify total number of tasks, median time per task, proportion of time per task, and common task combinations. Pharmacists' main tasks consisted of counselling, dispensing and management activities (27%, 21% and 17% respectively of the overall number of tasks) and these tasks also took the majority of their time. Tasks were frequent but short, with the average time per task ranging from 0.55 to 8.46 min and most time was spent in areas without the capacity for patient interaction (51% in the dispensing/compounding area and 6% in the back office). Pharmacies are dynamic environments with the average task taking 1-2 min. Longer interventions may not be easily integrated into current pharmacy workflow. Copyright © 2018 Elsevier Inc.

    2011-09-01

    Full Text Available Abstract Background Longitudinal time-activity data are important for exposure modeling, since the extent to which short-term time-activity data represent long-term activity patterns is not well understood. This study was designed to evaluate longitudinal variations in human time-activity patterns. Method We report on 24-hour recall diaries and questionnaires collected via the internet from 151 parents of young children (mostly under age 55, and from 55 older adults of ages 55 and older, for both a weekday and a weekend day every three months over an 18-month period. Parents also provided data for their children. The self-administrated diary and questionnaire distinguished ~30 frequently visited microenvironments and ~20 activities which we selected to represent opportunities for exposure to toxic environmental compounds. Due to the non-normal distribution of time-location/activity data, we employed generalized linear mixed-distribution mixed-effect models to examine intra- and inter-individual variations. Here we describe variation in the likelihood of and time spent engaging in an activity or being in a microenvironment by age group, day-type (weekday/weekend, season (warm/cool, sex, employment status, and over the follow-up period. Results As expected, day-type and season influence time spent in many location and activity categories. Longitudinal changes were also observed, e.g., young children slept less with increasing follow-up, transit time increased, and time spent on working and shopping decreased during the study, possibly related to human physiological changes with age and changes in macro-economic factors such as gas prices and the economic recession. Conclusions This study provides valuable new information about time-activity assessed longitudinally in three major age groups and greatly expands our knowledge about intra- and inter-individual variations in time-location/activity patterns.

    To examine medium- to long-term orthodontic treatment stability and its possible association with certain variables. In a retrospective longitudinal study of 70 postretention patients, the Peer Assessment Rating (PAR) index was measured at the start (T1) and end (T2) of treatment and between 4 and 10 years afterwards (T3). The stability was considered absolute when the T2 and T3 values were identical and relative when the difference was within the ±5 range. Among the 70 patients, 65.8% were female and 34.2% were male. Their mean age was 14.5 years. The mean treatment length was 2.4 years. The mean retention phase was 3.3 years. The mean pre- and posttreatment PAR scores were 29.8 (T1) and 6.3 (T2). The mean T1-T2 difference was 23.6. The mean T2-T3 difference was -0.39. Within the study, 7.1% presented absolute stability and 68.6% presented relative stability. Lower anterior segment alignment and overbite were the most unstable occlusal features and tended to worsen. Fixed retainer (odds ratio [OR] 0.31; 95% confidence interval [CI] 0.10-0.98) as a protective factor and years without retention (OR 1.32; 95% CI 1.03-1.68) as a risk factor are predictor variables of instability in the case of lower anterior segment alignment. The PAR value at the end of treatment (OR 1.29; 95% CI 1.08-1.54) and extractions (OR 4.76; 95% CI 1.05-21.6) before treatment are predictors for midline instability.

    2009-04-01

    To investigate the recruitment of 'niche' household populations, defined by their household characteristics and/or water supply type for health studies. The Australian Electoral Commission (AEC) database was used to recruit households for participation in two health-related studies, the first, a recycled water usage study and the second, an epidemiological study investigating household rainwater use. The AEC database facilitated the identification and recruitment of households using a particular water supply from among the general household population. The good utility of the AEC roll in household recruitment was associated with its coverage, accuracy and the ability to delimit the sampling frame according to the geographical area(s) and household characteristics of interest. Its use also allowed personalised contact to be made with potential survey participants by mail, contact that is not otherwise possible using existing telephone and on-line databases. The AEC database is a valuable resource for household recruitment in a diversity of health and environmental exposure surveys.

  19. What Images Reveal: a Comparative Study of Science Images between Australian and Taiwanese Junior High School Textbooks

    From a social semiotic perspective, image designs in science textbooks are inevitably influenced by the sociocultural context in which the books are produced. The learning environments of Australia and Taiwan vary greatly. Drawing on social semiotics and cognitive science, this study compares classificational images in Australian and Taiwanese junior high school science textbooks. Classificational images are important kinds of images, which can represent taxonomic relations among objects as reported by Kress and van Leeuwen (Reading images: the grammar of visual design, 2006). An analysis of the images from sample chapters in Australian and Taiwanese high school science textbooks showed that the majority of the Taiwanese images are covert taxonomies, which represent hierarchical relations implicitly. In contrast, Australian classificational images included diversified designs, but particularly types with a tree structure which depicted overt taxonomies, explicitly representing hierarchical super-ordinate and subordinate relations. Many of the Taiwanese images are reminiscent of the specimen images in eighteenth century science texts representing "what truly is", while more Australian images emphasize structural objectivity. Moreover, Australian images support cognitive functions which facilitate reading comprehension. The relationships between image designs and learning environments are discussed and implications for textbook research and design are addressed.

    Patients increasingly use social media to communicate. Their stories could support quality improvements in participatory health care and could support patient-centered care. Active use of social media by health care institutions could also speed up communication and information provision to patients and their families, thus increasing quality even more. Hospitals seem to be becoming aware of the benefits social media could offer. Data from the United States show that hospitals increasingly use social media, but it is unknown whether and how Western European hospitals use social media. To identify to what extent Western European hospitals use social media. In this longitudinal study, we explored the use of social media by hospitals in 12 Western European countries through an Internet search. We collected data for each country during the following three time periods: April to August 2009, August to December 2010, and April to July 2011. We included 873 hospitals from 12 Western European countries, of which 732 were general hospitals and 141 were university hospitals. The number of included hospitals per country ranged from 6 in Luxembourg to 347 in Germany. We found hospitals using social media in all countries. The use of social media increased significantly over time, especially for YouTube (n = 19, 2% to n = 172, 19.7%), LinkedIn (n =179, 20.5% to n = 278, 31.8%), and Facebook (n = 85, 10% to n = 585, 67.0%). Differences in social media usage between the included countries were significant. Social media awareness in Western European hospitals is growing, as well as its use. Social media usage differs significantly between countries. Except for the Netherlands and the United Kingdom, the group of hospitals that is using social media remains small. Usage of LinkedIn for recruitment shows the awareness of the potential of social media. Future research is needed to investigate how social media lead to improved health care.

    To examine the hypothesis that Holocaust exposure during young adulthood negatively affects physical aging, causing greater morbidity, faster deterioration in health parameters, and shorter survival. A longitudinal cohort study of the natural history of an age-homogenous representative sample born in 1920/21 and living in Jerusalem. Community-based home assessments. Four hundred fifty-eight subjects of European origin aged 70 at baseline and 77 at follow-up. Comprehensive assessment of physical, functional, and psychosocial domains; biographical history of concentration camp internment (Camp), exposure to Nazi occupation during World War II (Exposure), or lack thereof (Controls); and 7-year mortality data from the National Death Registry. Holocaust survivors of the Camp (n=93) and Exposure (n=129) groups were more likely than Controls (n=236) to be male and less educated and have less social support (P=.01), less physical activity (P=.03), greater difficulty in basic activities of daily living (P=.009), poorer self-rated health (P=.04), and greater usage of psychiatric medication (P=.008). No other differences in health parameters or physical illnesses were found. Holocaust survivors had similar rates of deterioration in health and illness parameters over the follow-up period, and 7-year mortality rates were identical. Proportional hazard models showed that being an elderly Holocaust survivor was not predictive of greater 7-year mortality. Fifty years after their Holocaust trauma, survivors still displayed significant psychosocial and functional impairment, although no evidence was found to support the hypothesis that the delayed effects of the trauma of the Holocaust negatively influence physical health, health trajectories, or mortality.

    Diabetes mellitus is an increasingly prevalent metabolic disorder that is associated with substantial disease burden. Australia has an opportunity to improve ways of caring for the growing number of people with diabetes, but this may require changes to the way care is funded, organised and delivered. To inform how best to care for people with diabetes, and to identify the extent of change that is required to achieve this, the Diabetes Care Project (DCP) will evaluate the impact of two different, evidence-based models of care (compared to usual care) on clinical quality, patient and provider experience, and cost. The DCP uses a pragmatic, cluster randomised controlled trial design. Accredited general practices that are situated within any of the seven Australian Medicare Locals/Divisions of General Practice that have agreed to take part in the study were invited to participate. Consenting practices will be randomly assigned to one of three treatment groups for approximately 18 to 22 months: (a) control group (usual care); (b) Intervention 1 (which tests improvements that could be made within the current funding model, facilitated through the use of an online chronic disease management network); or (c) Intervention 2 (which includes the same components as Intervention 1, as well as altered funding to support voluntary patient registration with their practice, incentive payments and a care facilitator). Adult patients who attend the enrolled practices and have established (≥12 month's duration) type 1 diabetes mellitus or newly diagnosed or established type 2 diabetes mellitus are invited to participate. Multiple outcomes will be studied, including changes in glycosylated haemoglobin (primary outcome), changes in other biochemical and clinical metrics, incidence of diabetes-related complications, quality of life, clinical depression, success of tailored care, patient and practitioner satisfaction, and budget sustainability. This project responds to a need for robust

    Obesity is common in young women, increasing insulin resistance (IR) and worsening pregnancy complications, including gestational diabetes (GDM). Women with polycystic ovary syndrome (PCOS) are commonly obese, which aggravates the severity of PCOS clinical expression. Relationships between these common insulin-resistant conditions, however, remain unclear. We conducted a secondary analysis of the Australian Longitudinal Study on Women's Health (ALSWH) database, including data from 8009 women aged 18-36 years across six surveys. We used latent-curve growth modelling to identify distinct body mass index (BMI) trajectories and multinomial logistic regression to explore sociodemographic and health variables characterizing BMI group membership. Logistic regression was used to assess independent risk of GDM. A total of 662 women (8.29%, 95% CI 7.68-8.89) reported PCOS. Three distinct BMI trajectories emerged, namely low stable (LSG) (63.8%), defined as an average trajectory remaining at ~25 kg/m 2 ; moderately rising (MRG) (28.8%), a curvilinear trajectory commencing in a healthy BMI and terminating in the overweight range; and high-rising (HRG) (7.4%), a curvilinear trajectory starting and terminating in the obese range. A high BMI in early reproductive life predicted membership in higher trajectories. The HRG BMI trajectory was independently associated with GDM (OR 2.50, 95% CI 1.80-3.48) and was a stronger correlate than PCOS (OR 1.89, 95% CI 1.41-2.54), maternal age, socioeconomic status, or parity. Our results suggest heterogeneity in BMI change among Australian women of reproductive age, with and without PCOS. Reducing early adult life weight represents an ideal opportunity to intervene at an early stage of reproductive life and decreases the risk of long-term metabolic complications such as GDM.

    Several North American studies have found a connection between domestic violence and animal abuse. This article reports on the first Australian research to examine this connection. A group of 102 women recruited through 24 domestic violence services in the state of Victoria and a nondomestic violence comparison group (102 women) recruited from the community took part in the study. Significantly higher rates of partner pet abuse, partner threats of pet abuse, and pet abuse by other family members were found in the violent families compared with the nondomestic violence group. As hypothesized, children from the violent families were reported by their mothers to have witnessed and committed significantly more animal abuse than children from the nonviolent families. Logistic regression analyses revealed, for the group as a whole, that a woman whose partner had threatened the pets was 5 times more likely to belong to the intimate partner violence group.

    2008-01-01

    Twin studies of diabetes mellitus can help elucidate genetic and environmental factors in etiology and can provide valuable biological samples for testing functional hypotheses, for example using expression and methylation studies of discordant pairs. We searched the volunteer Australian Twin...... Registry (19,387 pairs) for twins with diabetes using disease checklists from nine different surveys conducted from 1980-2000. After follow-up questionnaires to the twins and their doctors to confirm diagnoses, we eventually identified 46 pairs where one or both had type 1 diabetes (T1D), 113 pairs...... with type 2 diabetes (T2D), 41 female pairs with gestational diabetes (GD), 5 pairs with impaired glucose tolerance (IGT) and one pair with MODY. Heritabilities of T1D, T2D and GD were all high, but our samples did not have the power to detect effects of shared environment unless they were very large...

    Dog health in rural and remote Australian Indigenous communities is below urban averages in numerous respects. Many Indigenous communities have called for knowledge sharing in this area. However, dog health education programs are in their infancy, and lack data on effective practices. Without this core knowledge, health promotion efforts cannot progress effectively. This paper discusses a strategy that draws from successful approaches in human health and indigenous education, such as dadirri, and culturally respectful community engagement and development. Negotiating an appropriate education program is explored in its practical application through four case studies. Though each case was unique, the comparison of the four illustrated the importance of listening (community consultation), developing and maintaining relationships, community involvement and employment. The most successful case studies were those that could fully implement all four areas. Outcomes included improved local dog health capacity, local employment and engagement with the program and significantly improved dog health.

  5. Influence of comorbidities on therapeutic progression of diabetes treatment in Australian veterans: a cohort study.

    Directory of Open Access Journals (Sweden)

    Agnes I Vitry

    Full Text Available BACKGROUND: This study assessed whether the number of comorbid conditions unrelated to diabetes was associated with a delay in therapeutic progression of diabetes treatment in Australian veterans. METHODOLOGY/PRINCIPAL FINDINGS: A retrospective cohort study was undertaken using data from the Australian Department of Veterans' Affairs (DVA claims database between July 2000 and June 2008. The study included new users of metformin or sulfonylurea medicines. The outcome was the time to addition or switch to another antidiabetic treatment. The total number of comorbid conditions unrelated to diabetes was identified using the pharmaceutical-based comorbidity index, Rx-Risk-V. Competing risk regression analyses were conducted, with adjustments for a number of covariates that included age, gender, residential status, use of endocrinology service, number of hospitalisation episodes and adherence to diabetes medicines. Overall, 20,134 veterans were included in the study. At one year, 23.5% of patients with diabetes had a second medicine added or had switched to another medicine, with 41.4% progressing by 4 years. The number of unrelated comorbidities was significantly associated with the time to addition of an antidiabetic medicine or switch to insulin (subhazard ratio [SHR] 0.87 [95% CI 0.84-0.91], P<0.001. Depression, cancer, chronic obstructive pulmonary disease, dementia, and Parkinson's disease were individually associated with a decreased likelihood of therapeutic progression. Age, residential status, number of hospitalisations and adherence to anti-diabetic medicines delayed therapeutic progression. CONCLUSIONS/SIGNIFICANCE: Increasing numbers of unrelated conditions decreased the likelihood of therapeutic progression in veterans with diabetes. These results have implications for the development of quality measures, clinical guidelines and the construction of models of care for management of diabetes in elderly people with comorbidities.

  6. Bone loss rate in adrenal incidentalomas: a longitudinal study.

    Although by definition patients with adrenal incidentalomas (AI) do not have evident clinical syndromes, they may frequently suffer from subclinical hypercortisolism (SH). This is of some importance because of evidence that SH may lead to clinical complications, including bone loss. Thus, the understanding of bone involvement due to SH may be extremely important in the management of AI. Unfortunately, the available data on bone mineral density (BMD) in AI patients come from cross-sectional studies, which, to further complicate our understanding, are also conflicting, probably due to a different selection of patients and/or the variability in cortisol secretion (CS) often described in AI. To gain further insight about this topic, we performed a longitudinal study evaluating the rate of spinal and femoral bone loss levels in 24 females with AI. AI subjects were subdivided in two groups on the basis of the median of urinary cortisol secretion (UFC): group I (n = 12; UFC, 140.4 nmol/24 h). Spinal BMD was measured by both single energy quantitative computed tomography (L1-L4) and dual energy x-ray absorptiometry (DXA; L2-L4), and femoral BMD was determined by DXA. Bone loss rate was expressed as the change in z-score per yr. The spinal bone loss rate was higher (P < 0.005) in group II than in group I when measured by both quantitative computed tomography (-0.19 +/- 0.14 vs. 0.00 +/- 0.15) and DXA (-0.19 +/- 0.17 vs. 0.00 +/- 0.11). Moreover, CS and spinal bone loss rate were significantly correlated when patients were considered together. In conclusion, our data show that 1) AI patients with higher CS have increased lumbar trabecular bone loss rate than those with lower CS; and 2) the degree of spinal bone loss rate is related to the degree of CS. Thus, lumbar spine (LS) BMD has to be evaluated for well balanced decision-making on the treatment of choice for AI female patients.

    Background Oncology is a rapidly evolving field with continuous advancements in the diagnosis and treatment of cancer. Therefore, it is important that medical students are provided with the knowledge and experience required to care for oncology patients and enable them to diagnose and manage toxicities of novel therapeutic agents. Objective This study was performed to understand the medical students’ perspective of the oncology education provided in universities across Australia and identify areas of education that could potentially be modified or improved to ultimately attract more students to a career in oncology. Methods This pilot cross-sectional study consisted of an 18-question survey that was submitted online to medical students in their final year and interns rotating to the Tamworth Hospital. Results The survey was completed by 94 fifth-year medical students and interns. Oncology was taught both theoretically and clinically for 68% (63/93) of participants, and 48% (44/92) had an exclusive oncology rotation. Both theoretical and clinical oncology assessments were conducted for only 21% (19/92) of participants. Overall, 42% (38/91) of participants were satisfied with their oncology education, and 78% (40/51) were dissatisfied with the number of oncology teaching hours. The importance of a career in oncology was rated as low by 46% (41/90) of participants. Conclusions This pilot study indicates that there are potential areas to improve oncology teaching in Australian universities. The majority of surveyed students were dissatisfied with the number of teaching hours they receive in oncology. More global assessment of students and/or interns from other Australian institutes may yield further useful information. PMID:29233799

    Longitudinal studies that research homeless persons or transient drug users face particular challenges in retaining subjects. Between 2005 and 2006, 101 mobile young injection drug users were recruited in Los Angeles into a 2-year longitudinal study. Several features of ethnographic methodology, including fieldwork and qualitative interviews, and modifications to the original design, such as toll-free calls routed directly to ethnographer cell phones and wiring incentive payments, resulted in retention of 78% of subjects for the first follow-up interview. Longitudinal studies that are flexible and based upon qualitative methodologies are more likely to retain mobile subjects while also uncovering emergent research findings. PMID:20222779

    The aim of this cross-sectional study was to investigate the association between sedative load and functional outcomes in community-dwelling older Australian men. A total of 1696 males aged ≥ 70 years, enrolled in the Concord Health and Ageing in Men Project, were studied. Participants underwent assessments during 2005-2007. Sedative load was computed using a published model. Outcomes included activities of daily living (ADL), instrumental activities of daily living (IADL), physical performance measures and a clinical diagnosis of cognitive impairment. Of the participants, 15.3% took medications with sedative properties. After adjusting for age, education, depressive symptoms and comorbidities, participants who took one medication with sedation as a prominent side effect (sedative load = 1) had odds ratio (OR) of 2.15 (95% confidence interval, CI: 1.20-3.85) for ADL disability, compared with participants with sedative load = 0. Participants who took at least one primary sedative or two medications with sedation as a prominent side effect (sedative load ≥ 2) had an OR of 1.55 (95% CI: 1.02-2.35) for IADL disability, compared with participants with sedative load = 0. The mean 6-m walking speed (P = 0.001) and grip strength (P = 0.003) were significantly different between sedative load groups in unadjusted models only. No association between sedative load and poorer performance on balance and chair stands tests or cognitive impairment was observed. Participants with sedative load of one were more likely to report ADL disability, whereas participants with sedative load of ≥2 were more likely to report IADL disability. Higher sedative load was not associated with poorer physical performance or cognitive impairment in older Australian men. © 2012 The Authors Fundamental and Clinical Pharmacology © 2012 Société Française de Pharmacologie et de Thérapeutique.

    To examine the quality and safety of nurse practitioner services of two newly implemented nurse practitioner models of care at a correctional facility. Nurse practitioners could help to meet the physical and mental health needs of Australia's growing prison population; however, the nurse practitioner role has not previously been evaluated in this context. A quality assurance study conducted in an Australian prison where a primary health nurse practitioner and a mental health nurse practitioner were incorporated into an existing primary healthcare service. The study was guided by Donabedian's structure, processes and outcomes framework. Routinely collected information included surveys of staff attitudes to the implementation of the nurse practitioner models (n = 21 staff), consultation records describing clinical processes and time use (n = 289 consultations), and a patient satisfaction survey (n = 29 patients). Data were analysed descriptively and compared to external benchmarks where available. Over the two-month period, the nurse practitioners provided 289 consultations to 208 prisoners. The presenting problems treated indicated that most referrals were appropriate. A significant proportion of consultations involved medication review and management. Both nurse practitioners spent more than half of their time on individual patient-related care. Overall, multidisciplinary team staff agreed that the nurse practitioner services were necessary, safe, met patient need and reduced treatment delays. Findings suggest that the implementation of nurse practitioners into Australian correctional facilities is acceptable and feasible and has the potential to improve prisoners' access to health services. Structural factors (e.g., room availability and limited access to prisoners) may have reduced the efficiency of the nurse practitioners' clinical processes and service implementation. Results suggest that nurse practitioner models can be successfully integrated into a

    To explore the association between psychotropic drug use and alcohol drinking in community-dwelling older Australian men. We conducted a cross-sectional population-based study using baseline data collected between 2005 and 2007 from 1705 participants in the Concord Health and Ageing in Men Project (CHAMP) conducted in Sydney, Australia. All participants were men aged ≥70 years. The prevalence of antidepressant and sedative or anxiolytic drug use was ascertained at clinical examinations and alcohol drinking was self-reported. Logistic regression models were used to compute the unadjusted and adjusted prevalence ratios and 95% confidence intervals for the association between sedative or anxiolytic use and antidepressant use with drinking patterns. In the study sample, 8.0% used an antidepressant, 5.7% used a sedative or anxiolytic, 33.7% were daily drinkers, 13.9% were binge drinkers, 19.2% were heavy drinkers and 11.0% were problem drinkers. Overall, 27.1% of antidepressant users were daily drinkers and 42.7% of sedative or anxiolytic users were daily drinkers. Sedative or anxiolytic use was associated with daily drinking (prevalence ratio = 1.42; 95% confidence intervals 1.09-1.76) but not with other drinking patterns. The associations between antidepressant use and alcohol drinking were not statistically significant. Potential psychotropic drug-alcohol interactions were common in older Australian men. Users of sedative or anxiolytic drugs were more likely to engage in daily drinking compared with non-users of sedative or anxiolytic drugs. Clinicians should monitor patients prescribed sedative or anxiolytic drugs for possible adverse events arising from concomitant use with alcohol. © 2012 Australasian Professional Society on Alcohol and other Drugs.

    To determine the proportion of older Australian men who meet the Pharmaceutical Benefits Scheme (PBS) criteria for osteoporosis treatment and are receiving effective treatment. A population-based, cross-sectional analysis of the baseline phase of the Concord Health and Ageing in Men Project (CHAMP), a large epidemiological study focusing on the health of older men. Data were collected through questionnaires and clinical assessments. Bone mineral density (BMD) of the hip and spine was measured by dual x-ray absorptiometry (DXA). Vertebral deformities were identified from DXA lateral vertebral fracture assessment images. The study was conducted at Concord Hospital, Sydney, between January 2005 and May 2007. 1705 community-dwelling men aged 70 years or over from a defined geographical region around Concord Hospital. Prevalence of vertebral deformities; previous minimal trauma fractures; BMD T-scores ≤ - 3; falls in the previous 12 months; use of bisphosphonates and calcium and vitamin D supplements. Of the 1705 men seen at baseline, 1626 completed all DXA scans and 401 (25%) met one or more of the PBS criteria for osteoporosis treatment. Ninety per cent of the men who met the PBS criteria were unaware they had osteoporosis. Of the men eligible for PBS-subsidised treatment, 39 (10%) reported use of a bisphosphonate, 56 (14%) had taken calcium supplements, and 28 (7%) had taken vitamin D supplements. Only three men had taken calcium, vitamin D and bisphosphonates in combination. Despite a high prevalence of osteoporosis in elderly Australian men, awareness, diagnosis and treatment of the condition remain very low.

    Anxiety disorders are the most prevalent mental health condition in Australia. In addition, there are many people who experience problematic anxiety symptoms who do not receive an anxiety disorder diagnosis but require treatment. As herbal medicine use is popular in Australia, and little is known about how adults experiencing anxiety are using these medicines, this study aimed to identify how Australian adults who experience anxiety are using herbal medicines. An online cross-sectional descriptive study was conducted using purposive convenience sampling to recruit Australian adults who have experienced anxiety symptoms and have used herbal medicines (N = 400). Descriptive statistics, chi-square test of contingency, analysis of variance, and simple logistic regression was used to analyse the data. Eighty two percent of participants experienced anxiety symptoms in the previous 12 months, with 47% reporting having previously been diagnosed with an anxiety disorder. In addition, 72.8% had used herbal medicines specifically for anxiety symptoms in their lifetime, while 55.3% had used prescribed pharmaceuticals, with 27.5% having used herbal medicines concurrently with prescribed pharmaceuticals. The Internet and family and friends were the most frequently used sources of information about herbal medicines. Forty eight percent of participants did not disclose their herbal medicine use to their doctor. Herbal medicines are being used by adults with anxiety and are commonly self-prescribed for anxiety symptoms. Health practitioners who are experts in herbal medicine prescribing are consulted infrequently. In addition, herbal medicine use is often not disclosed to health practitioners. These behaviours are concerning as people may not be receiving the most suitable treatments, and their use of herbal medicines may even be dangerous. It is critical we develop a better understanding of why people are using these medicines, and how we can develop improved health literacy

    1999-07-01

    A study was conducted in Sydney, Australia, in 1996 to investigate the current exposure levels, control technologies, and work practices in five service garages (four car and one bus), three brake bonding workshops, and one gasket processing workshop. This study formed part of the assessment of chrysotile as a priority existing chemical under the Australian National Industrial Chemicals Notification and Assessment Scheme. A total of 68 (11 personal and 57 area) air samples were collected, in accordance with the Australian standard membrane filter method. Fiber concentrations were determined by the traditional phase contrast microscopy (PCM) method and 16 selected samples were analyzed by the more powerful transmission electron microscopy (TEM). Chrysotile exposure of car mechanics measured by PCM was typically below the reportable detection limit of 0.05 f/mL, irrespective of whether disc brake, drum brake, or clutch was being serviced. These low levels can be attributed to the wet cleaning or aerosol spray methods used in recent years to replace the traditional compressed air jet cleaning. In the three brake shoe relining workshops, task-specific exposure reached up to 0.16 f/mL in the processes of cutting and radius grinding. TEM results were generally higher, due to its higher resolution power. The median diameter on samples taken from the service garages (passenger cars), as determined by TEM, was 0.5-1.0 micron; and was between 0.2-0.5 micron for the brake bonding and gasket processing workshops, while that for the bus service depot was 0.1-0.2 micron. Most of the respirable fibers (84%, mainly forsterite) from the bus service depot were below 0.2 micron in diameter which is the resolution limit of PCM. In the brake bonding and gasket cutting workshops, 34 percent and 44 percent of the chrysotile fibers were below 0.2 micron in diameter.

    Universities' responsibility to ensure academic integrity is frustrated by software and communication tools that facilitate content reuse coupled with a growing international essay writing economy. A wide range of behaviours constitute academic dishonesty and while a complex phenomenon to examine, existing evidence suggests that there is sufficient proliferation (both in volume and variety) of these behaviours among Australian university students to warrant concern. This proliferation presents faculty and staff with new challenges in ensuring academic integrity. This paper reports findings of a nationwide cross-sectional survey of 361 students enrolled in an Australian nursing degree program and describes the extent of academic dishonesty among those surveyed. An online survey adapted from previous work was used to collect data on academic dishonesty, professional dishonesty and social desirability bias. Analysis of this data enabled identification of the prevalence of dishonesty, relationships between individual characteristics and dishonest behaviours, associations between academic and professional dishonesty, and the impact of deterrents to such behaviour. Plagiarism was the most frequently reported form of academic misconduct. Most participants indicated that threat of severe punishment and signing of verification statements would deter undesirable academic behaviour. Despite this, a relatively high proportion of students reported engaging in at least one form of academic misconduct, the likelihood of which was higher among younger age groups. Of concern was that a correlation was found between academic and professional misconduct, the most common being the recording of inaccurate or fabricated vital signs and breaching client privacy. In health professional education, there is a tendency to assume that the nobility of these disciplines would result in a lower incidence of cheating behaviours. The findings of this study support existing literature that refutes

    From the pre-teen to the mid-teen years, rates of alcohol use and misuse increase rapidly. Cross-sectional research shows that positive family emotional climate (low conflict, high closeness) is protective, and there is emerging evidence that these protective mechanisms are different for girls versus boys. The aim of this study was to explore gender differences in the longitudinal impact of family emotional climate on adolescent alcohol use and exposure to peer drinking networks. Three-wave two-level (individual, within-individual over time) ordinal logistic regression with alcohol use in the past year as the dependent measure and family variables lagged by 1 year. Adolescents completed surveys during school hours. A total of 855 Australian students (modal age 10-11 years at baseline) participating in the International Youth Development Study (Victoria, Australia). These included emotional closeness to mother/father, family conflict, parent disapproval of alcohol use and peer alcohol use. For girls, the effect of emotional closeness to mothers on alcohol use was mediated by exposure to high-risk peer networks. Parent disapproval of alcohol use was protective for both genders, but this effect was larger for boys versus girls, and there was no evidence that peer use mediated this effect. Peer drinking networks showed stronger direct risk effects than family variables. Family factors unidirectionally impact on growth in adolescent alcohol use and effects vary with child gender. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

    Psychosocial assessment and depression screening are recommended for all pregnant and postnatal women in Australia. However, women who give birth in private maternity settings remain less likely to participate in psychosocial assessment programs, making it difficult to comment on the potential resource implications. To describe the psychosocial profile of a sample of women who had recently given birth in a private hospital and to examine the acceptability and feasibility of introducing psychosocial assessment as a routine component of maternity care. Two hundred and twenty participants were recruited in a four-month period from a private tertiary hospital located in Murdoch, Western Australia. All participants completed the Edinburgh Depression Scale (EDS) and a Antenatal Risk Questionnaire (ANRQ) prior to discharge via an iPad. The mean total score for the EDS was 4.77 (SD = 3.93), with 5% of women scoring above the recommended cut-off of 13 or more. The mean total score for the ANRQ was 17.73 (SD = 10.72). 45.0% of all women endorsed no significant risk factors. The proportion of women scoring above the recommended ANRQ cut-off of 23 or more was 32.3%. Approximately 11% of women were referred for additional support or treatment. Acceptability of the ANRQ was high at 97.3%. This study describes the psychosocial profile of a sample of women who recently gave birth in an Australian private maternity hospital and demonstrates that with additional resources, the implementation of psychosocial assessment as a routine component of maternity care was feasible and highly acceptable in this setting. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Post laser-assisted in situ keratomileusis (LASIK) ectasia is a rare and unpredictable complication after LASIK. Corneal collagen crosslinking (CXL) has emerged as a promising technique to address this complication. Our study evaluates the long-term efficacy of CXL for post-LASIK ectasia in an Australian setting. Retrospective review of post-LASIK ectasia patients referred to and treated at 3 corneal refractive surgery institutions in Sydney, Australia. Eleven patients (14 eyes; mean age, 39.7 ± 12.6 years) underwent epithelium-off CXL with follow-up ranging from 12-78 months. Best spectacle-corrected visual acuity (BSCVA), simulated keratometry, corneal topography indices, and higher-order aberrations (HOAs) [mean ± standard error of the mean (SEM)] were measured with a rotating Scheimpflug camera (Pentacam, Oculus). Comparisons between baseline measurements and postoperative outcomes were performed using paired t test analysis. At last follow-up, BSCVA improved significantly by 0.2 ± 0.06 logMAR (P = 0.01), and 12 of 14 eyes showed no keratometric deterioration. Of the corneal topography indices, index of height asymmetry showed a trend toward a significant improvement (P = 0.05). There was no progression of corneal HOAs. Central corneal thickness was not significantly altered (P = 0.6). No major postoperative complications were observed. In the Australian setting, CXL has proven effective at stabilizing the progression of post-LASIK ectasia, inducing corneal regularity, and improving visual acuity.

    One in two Indigenous Australian pregnant women smoke, yet little is known about their trajectory of smoking. This study aimed to explore Aboriginal women's narratives from starting smoking through to pregnancy. A female Aboriginal Researcher conducted individual face-to-face interviews with 20 Aboriginal women from New South Wales, Australia. Recruitment, through Aboriginal services and community networks, continued until saturation was reached. Audio-recorded transcripts were independently open coded by two researchers, inductively analysed and reported using a three-dimensional structure of looking backwards, forwards, inwards, outwards and a sense of place, to elucidate the chronology of events, life stages, characters, environments, and turning points of the stories. A chronology emerged from smoking initiation in childhood, coming of age, becoming pregnant, through to attempts at quitting, and relapse post-partum. Several new themes emerged: the role mothers play in women's smoking and quitting; the contribution of nausea to spontaneous quitting; depression as a barrier to quitting; and the hopes of women for their own and their children's future. The epiphany of pregnancy was a key turning point for many - including the interplay of successive pregnancies; and the intensity of expressed regret. Aboriginal women report multiple influences in the progression of early smoking to pregnancy and beyond. Potential opportunities to intervene include: a) childhood, coming of age, pregnancy, post-natal, in-between births; b) key influencers; c) environments, and d) targeting concurrent substance use. Morning sickness appears to be a natural deterrent to continued smoking. Depression, and its relationship to smoking and quitting in Australian Indigenous pregnant women, requires further research.

    This study aims to describe the Australian complementary medicine (CM) workforce, including practice and professional characteristics. National cross-sectional survey. Australia. Any individual who self-identified as a practitioner qualified in any one of 14 CM professions and working in any state or territory of Australia was eligible to participate in the survey. A 19-item online survey was developed following a review of existing CM workforce data and in alignment with other CM workforce survey projects in progress at the time. The survey items were presented under three main constructs: demographic characteristics, professional characteristics, and practice characteristics. Descriptive statistical analysis, including frequencies and percentages, of multiple choice survey items was used. Open response items were analyzed to determine the mean, standard deviation (SD), minimum, and maximum. The demographic data were evaluated for representativeness based on previously reported CM workforce figures. The survey was completed by 1306 CM practitioners and was found to be nationally representative compared with the most recent registrant data from the Chinese Medicine Board of Australia. Participants primarily practiced in the most populous Australian states and worked in at least one urban clinical location. Most participants held an Advanced Diploma qualification or lower, obtained their qualification ten more years ago, and practiced in a clinical environment alongside at least one other practitioner from another health profession. Participants reported diverse clinical practice specialties and occupational roles. Per week, participants worked an average of 3.7 days and treated 23.6 clients. The results from this survey of practitioners from most complementary professions in Australia provide new insights into the national complementary medicine workforce. Further exploration of the CM workforce is warranted to inform all who provide patient care and develop health

    Full Text Available Abstract Background Diabetes has been identified as one of the national health priority areas in Australia. After 20 years of diabetes most patients can be expected to develop diabetic retinopathy which, if undetected, is likely to cause significant visual loss or blindness. This paper reports on a pilot study aimed to test the ability of Australian GPs to clinically recognise diabetic retinopathy following a brief training intervention. Method 17 GPs from a Brisbane Division of General Practice were recruited to participate in a clinical upskilling intervention pilot. Participant scores on clinical assessments were used to analyse GP sensitivity and specificity in screening for diabetic retinopathy. Results were compared with the NHMRC guidelines for acceptable screening accuracy. Results Ten of the 17 GPs (59% achieved a screening sensitivity of 25% or less in the pre test, three (18% a sensitivity of 50%, and four (23% achieved a sensitivity of ≥ 75%. In the post-test, all seventeen GPs achieved between 50 and 100% sensitivity. In the pre-test, thirteen (76% GPs achieved a screening specificity of less than or equal to 50%, and four (23% a specificity of 75 %. In the post test, four GPs (23% rated a screening specificity of less than 50%, six (35% achieved a specificity of 66%, and seven (41% 100% specificity. Conclusion 24% of GPs met the NHMRC diabetic retinopathy screening criterion prior to the workshop, and 94% following this brief training intervention. Australian GPs are capable of a much more significant role in community screening for diabetic retinopathy.

    to describe the prevalence and impact on quality of life of urinary incontinence in a population-based cohort of older community-dwelling Australian men. the population comprised 1,705 men aged >or=70 years participating in the Concord Health and Ageing in Men Project, a population-based study of urban older Australian men. data were collected between January 2005 and June 2007, and the participation rate was 47%. Data on demographics, medical history and from the 12-item Short Form Health Survey (SF-12) and International Consultation on Incontinence Questionnaire were collected. Urinary incontinence was defined as urinary leakage at least two times a week over the past 4 weeks. the prevalence of urinary incontinence was 14.8%, increasing from 12.0% for men aged 70-74 years old to 16.3% for those aged >or=90 years, with urgency incontinence being the most frequent type of urinary incontinence. Daily urine leakage was reported by 3% of men. Men with incontinence had lower overall SF-12 scores with greater impact on the physical (PCS) than the mental (MCS) components of that scale. After adjusting for age, number of co-morbidities, enlarged prostate and prostate cancer, men with incontinence had worse PCS (43.6 vs 45.9) and MCS scores (52.2 vs 54.6) compared with continent men. urinary incontinence is common among older community-dwelling men and is associated with worse quality of life with greater impact on physical than mental factors. As the population ages, urinary incontinence prevalence will increase and increased resources will be needed to address this growing problem.

    Full Text Available Abstract Background Attention-Deficit/Hyperactivity Disorder (ADHD affects approximately 5% of children worldwide and results in significant impairments in daily functioning. Few community-ascertained samples of children with ADHD have been studied prospectively to identify factors associated with differential outcomes. The Children’s Attention Project is the first such study in Australia, examining the mental health, social, academic and quality of life outcomes for children with diagnostically-confirmed ADHD compared to non-ADHD controls. The study aims to map the course of ADHD symptoms over time and to identify risk and protective factors associated with differential outcomes. Methods/design The sample for this prospective longitudinal study is being recruited across 43 socio-economically diverse primary schools across Melbourne, Australia. All children in Grade 1, the second year of formal schooling (6–8 years, are screened for ADHD symptoms using independent parent and teacher reports on the Conners’ 3 ADHD index (~N = 5260. Children screening positive for ADHD by both parent and teacher report, and a matched sample (gender, school screening negative, are invited to participate in the longitudinal study. At baseline this involves parent completion of the NIMH Diagnostic Interview Schedule for Children IV (DISC-IV to confirm likely ADHD diagnostic status and identify other mental health difficulties, direct child assessments (cognitive, academic, language and executive functioning; height and weight and questionnaires for parents and teachers assessing outcomes, as well as a broad range of risk and protective factors (child, parent/family, teacher/school, and socio-economic factors. Families will be initially followed up for 3 years.

    Full Text Available Background. It is established that there is an anatomical relationship between the corpus callosum and longitudinal strips. These formations must correlate to the common commissural system of the corpus callosum conductors. At present this issue in such a formulation is not considered in literature on Neuromorphology. Objective. The study was aimed to determine the commutations between the longitudinal strips and commissural conductors of the corpus callosum. Methods. The corpus callosum of people aged from 36 to 60 was studied. Some slices of the corpus callosum stem were used for impregnation and then inserted in paraffin blocks. Another part of these slices was subjected to plastination in epoxy resin. Results. Lateral longitudinal strips contain significantly greater mass of nerve conductors. Most of them compactly pass along limbic ring, while the other part is combined to nerve fibres of the corpus callosum commissural cords. The longitudinal strips are coated with an outer limiting glial membrane (grey coating. Conclusions. By means of the corpus callosum the connections between conscious and subconscious brain areas are structurally fixed. It can be assumed that longitudinal strips have relation to hippocampal area, related to the ancient formation of the pallium. This does not exclude the fact that the nerve fibres, found within longitudinal strips may have projections on the cortical cells of vaulted gyrus, which is considered to be paleopallium sphere. So, this interaction between the ancient and the old cortex should presumably be carried out by means of lateral longitudinal strips.

    2015-02-01

    Few longitudinal studies have investigated how cyberbullying interacts with traditional bullying among young people, who are increasingly using online environments to seek information, entertainment and to socialise. This study aimed to identify the associations between the relative contribution of cyberbullying victimisation and traditional bullying victimisation on social and emotional antecedents and outcomes among adolescents. Participants were a cohort of 1,504 adolescents from 16 Australian schools followed from age 13 to 15 years. Adolescents experiencing social and emotional difficulties were more likely to be cyberbullied and traditionally bullied, than traditionally bullied only. Those targeted in both ways experienced more harm and stayed away from school more often than those traditionally bullied only. These findings suggest a high coexistence of cyber and traditional bullying behaviours and their antecedents, and higher levels of harm from a combination of these behaviours for adolescents over time. Future research should engage students as co-researchers to enhance school and parent strategies to support adolescents experiencing difficulties, and to reduce the likelihood of both cyber and traditional bullying.

    Full Text Available Associations between carotid artery longitudinal displacement, cardiovascular disease risk factors, and events were evaluated in a large, multi-ethnic cohort.A novel, reproducible protocol was developed for measuring right common carotid artery longitudinal displacement using ultrasound speckle-tracking. Total longitudinal displacement was measured in 389 randomly selected participants from the Multi-Ethnic Study of Atherosclerosis that were free of cardiovascular disease at baseline. Univariate analyses and Pearson Correlations were used to define relationships between longitudinal displacement with traditional cardiovascular risk factors and traditional measures of arterial stiffness. Hazard ratios of longitudinal displacement for cardiovascular disease and coronary heart disease events were compared using Cox proportional hazards models.Participants were a mean (standard deviation 59.0 (8.7 years old, 48% female, 39% White, 26% Black, 22% Hispanic, and 14% Chinese. They had 19 (4.9% cardiovascular disease and 14 (3.6% coronary heart disease events over a mean 9.5 years of follow-up. Less longitudinal displacement was associated with Chinese (β = -0.11, p = 0.02 compared to White race/ethnicity and greater longitudinal displacement was associated with higher carotid intima-media thickness (β = 0.26, p = 0.004.

    2017-06-01

    The academic success and degree completion of tertiary students depends on their academic performance (AP), commonly measured by the percentage grades for the units they complete. No research has examined whether occupational therapy students' approaches to study are predictive of their AP. This study investigated whether approaches to study were predictive of the AP among a group of Australian undergraduate occupational therapy students. A total of 376 undergraduate occupational therapy students completed the Approaches and Study Skills Inventory for Students (ASSIST). Regression analysis was conducted using a range of demographic characteristics and the ASSIST scores as independent variables with students' self-reported by their self-reported mean percentage grade range (as a proxy indicator of their AP) as the dependent variable. The deep and the strategic approaches to study were not significantly correlated with occupational therapy students' AP. The ASSIST fear of failure subscale of the surface approach to study had a unique contribution to AP, accounting for 1.3% of its total variance. Occupational therapy students' year level of enrolment made a unique contribution to their AP, accounting for 4.2% of the total variance. Age and gender made a unique contribution to AP as well although their impact was small. Undergraduate occupational therapy students' approaches to study were predictive of their AP to a very limited degree. However, their AP was predicted by a number of demographic variables, including age, gender and year level of enrolment.

    2011-08-01

    Although Chinese-Australian women are at higher risk of developing breast cancer after migration to Australia, information on their experience is limited. This paper explores Chinese-Australian women's perceptions of the meaning and experience of a breast cancer diagnosis, treatment and coping mechanism. Three focus groups were conducted with 23 Chinese-Australian women diagnosed with breast cancer in their native language (Cantonese or Mandarin). Following transcription and translation, interview data was analysed by content analysis. Culturally specific values, beliefs and language barriers played a significant role in shaping the women's breast cancer experiences and their response to the diagnosis. Of note these women found the experience isolating and distressing, factors that were compounded by the lack of culturally sensitive resources and information. In providing information for Chinese-Australian women with breast cancer, culture, language and migration experience need to be taken into account.

  1. Use of missing data methods in longitudinal studies: the persistence of bad practices in developmental psychology.

    Jelicić, Helena; Phelps, Erin; Lerner, Richard M

    2009-07-01

    Developmental science rests on describing, explaining, and optimizing intraindividual changes and, hence, empirically requires longitudinal research. Problems of missing data arise in most longitudinal studies, thus creating challenges for interpreting the substance and structure of intraindividual change. Using a sample of reports of longitudinal studies obtained from three flagship developmental journals-Child Development, Developmental Psychology, and Journal of Research on Adolescence-we examined the number of longitudinal studies reporting missing data and the missing data techniques used. Of the 100 longitudinal studies sampled, 57 either reported having missing data or had discrepancies in sample sizes reported for different analyses. The majority of these studies (82%) used missing data techniques that are statistically problematic (either listwise deletion or pairwise deletion) and not among the methods recommended by statisticians (i.e., the direct maximum likelihood method and the multiple imputation method). Implications of these results for developmental theory and application, and the need for understanding the consequences of using statistically inappropriate missing data techniques with actual longitudinal data sets, are discussed.

    To examine the health of prisoners and ex-prisoners in Fiji, including risk behaviours, service access and HIV status. Longitudinal study of 198 men and women recruited prior to release from prison in Fiji, interviewed in the weeks preceding release, and again 1 and 4 months post-release. Dried blood spot samples taken at baseline were tested for HIV. Eighty percent of participants completed at least one follow-up interview. The prevalence of HIV was low (1%), despite evidence of widespread STI and BBV risk behaviours. A history of risky substance use was normative and more than a third reported high psychological distress prior to release. Fewer than one in four reported accessing health care within a month of release from prison. The health needs of this population are significant but differ in important ways from those of incarcerated populations in other countries. Further research is needed to inform evidence-based care for prisoners and ex-prisoners in Pacific Island nations. © The Royal Australian and New Zealand College of Psychiatrists 2015.

    Adolescents' perceptions of parenting style and parental involvement in their education were examined longitudinally and related to school dropout among Icelandic youth (N = 427). Results indicated that adolescents who, at age 14, characterized their parents as authoritative (showing acceptance and supervision) were more likely to have completed upper secondary school by age 22 than adolescents from non-authoritative families, controlling for adolescents' gender, socioeconomic status (SES), temperament, and parental involvement. Parenting style seems to more strongly predict school dropout than parental involvement. Further, parenting style may moderate the relationship between parental involvement and dropout, but not in all groups; only in authoritative families does parental involvement decrease the likelihood of school dropout. Furthermore, even after controlling for previous academic achievement, adolescents from authoritative families were less likely to drop out than adolescents from authoritarian and neglectful families. These findings emphasize the importance of encouraging quality parent-child relationships in order to reduce the likelihood of school dropout.

    While cluster A personality disorders (PDs) have been shown to be moderately heritable, we know little about the temporal stability of these genetic risk factors. Paranoid PD (PPD) and schizotypal PD (STPD) were assessed using the Structured Interview for DSM-IV Personality in 2793 young adult twins from the Norwegian Institute of Public Health Twin Panel at wave 1 and 2282 twins on average 10 years later at wave 2. Using the program Mx, we fitted a longitudinal latent factor model using the number of endorsed criteria for PPD and STPD. The stability over time of the criteria counts for PPD and STPD, estimated as polychoric correlations, were +0.34 and +0.40, respectively. The best-fit longitudinal model included only additive genetic and individual-specific environmental factors with parameter estimates constrained to equality across the two waves. The cross-wave genetic and individual-specific environmental correlations for a latent cluster A factor were estimated to equal +1.00 and +0.13, respectively. The cross-time correlations for genetic and environmental effects specific to the individual PDs were estimated at +1.00 and +0.16-0.20, respectively. We found that 68% and 71% of the temporal stability of PPD and STPD derived, respectively, from the effect of genetic factors. Shared genetic risk factors for two of the cluster A PDs are highly stable in adults over a 10-year period while environmental risk factors are relatively transient. Over two-thirds of the long-term stability of the common cluster A PD liability can be attributed to genetic influences.

    Child abuse exerts a deleterious impact on a broad array of mental health outcomes. However, the neurobiological mechanisms that mediate this association remain poorly characterized. Here, we use a longitudinal design to prospectively identify neural mediators of the association between child abuse and psychiatric disorders in a community sample of adolescents. Structural magnetic resonance imaging (MRI) data and assessments of mental health were acquired for 51 adolescents (aged 13-20; M=16.96; SD=1.51), 19 of whom were exposed to physical or sexual abuse. Participants were assessed for abuse exposure (time 1), participated in MRI scanning and a diagnostic structured interview (time 2), and 2 years later were followed-up to assess psychopathology (time 3). We examined associations between child abuse and neural structure, and identified whether abuse-related differences in neural structure prospectively predicted psychiatric symptoms. Abuse was associated with reduced cortical thickness in medial and lateral prefrontal and temporal lobe regions. Thickness of the left and right parahippocampal gyrus predicted antisocial behavior symptoms, and thickness of the middle temporal gyrus predicted symptoms of generalized anxiety disorder. Thickness of the left parahippocampal gyrus mediated the longitudinal association of abuse with antisocial behavior. Child abuse is associated with widespread disruptions in cortical structure, and these disruptions are selectively associated with increased vulnerability to internalizing and externalizing psychopathology. Identifying predictive biomarkers of vulnerability following childhood maltreatment may uncover neurodevelopmental mechanisms linking environmental experience with the onset of psychopathology.

    Full Text Available his study investigates the preventative therapeutics of two major Australian mental health organisations - beyondblue and The Black Dog Institute. The aim of this study is to examine how the resilience-based programs of both organisations reconfigure clinical and preventative expertise into new forms of ‘anticipatory action' (Anderson 2010. First, this article situates beyondblue and the Black Dog Institute within their historical contexts to consider how issues of risk and protection have become essential to mental health care today. Second, it examines the institutional practices of beyondblue and the Black Dog Institute and the role of clinical and preventative expertise as enacted forms of authority. Finally, this study investigates the intellectual and biokeeping technologies promoted through both organisations“ resilience-based pedagogies. The view taken in this study is that such technologies actively participate in the making of new therapeutic cultures and practices. Moreover, as biomarkers continue to act as indicators of future states of ‘unhealth' (Dumit 2012: 112, biokeeping technologies will continue to act as essential elements in the governmentality of mental health and wellbeing.

    Full Text Available Rapid developments in ICT are extending and transforming the ways public services are delivered to citizens. The area of public healthcare has always been viewed as particularly as information intensive. This phenomenon is made more complex by rapid changes and continual increases in technological capability as well as increasing demands for new functions by users. Therefore, when conducting research in this area it is essential to take a holistic approach that integrates the latest ICT tools and processes with the needs of individuals. Q methodology is a research design that provides a foundation for the systematic study of subjectivity. The use of Q in the dynamic health context, we propose, is appropriate as a way of fostering deeper understandings of online public health phenomena. This paper reports on the results of a subjective study of the usefulness and usability of online public health information systems. The study used Q-methodology to investigate the perceptions of an Australian palliative care website with a group of available potential users of the website, which was composed of medical practitioners and students, and the general public, mostly from the computer-literate academic community. The most significant finding of this subjective study of internet-literate participants’ perceptions towards online palliative care is the recognition of four groups: interactive, superficial, medical and service.

    Full Text Available Abstract Background Sexual difficulties (SD are common among men of all ages and can have considerable impact on quality of life and indications for future health. SD are associated with mental and physical wellbeing and with relationship satisfaction, yet they are rarely discussed with medical professionals who are often ill equipped to assess and manage them. This paper provides an updated overview on the status of SD in Australian men from 18 to 55 years of age and will form a baseline comparison for future analyses of SD based on Ten to Men data. Methods We used data from Ten to Men, the Australian Longitudinal Study on Male Health. SD was measured using eight items capturing specific sexual difficulties. We examined associations of a range of health and lifestyle factors (smoking, alcohol consumption, illicit drug use, obesity and new sexual partners, self-rated health status, disability, pain medication, diagnosed physical and mental health conditions with each SD using logistic regression. The sample included 12,636 adult males who had previously been sexually active. Analysis was stratified by age (18–34 years versus 35–55 years. Results This paper shows that experiencing SD is relatively common among Australian men – overall half the sample (54 %; 95 % CI: 0.53–0.55 experienced at least one SD for more than 3 months over the past 12 months. While more common in older men aged 45 to 55 years, almost half the 18 to 24 year old men (48 % also reported at least one SD highlighting that SD affects men of all ages. We found that SDs were associated with both lifestyle and health factors, although the strongest associations were observed for health factors in both age groups, in particular poor self-rated health, having a disability and at least one mental health condition. Lifestyle factors associated with SDs in men of all ages included smoking, harmful alcohol consumption and drug use in the past 12 months. Obesity was

    To examine the longitudinal association between age and intraocular pressure (IOP) in a large sample of Korean men and women. We conducted a prospective cohort study of 274,064 young and middle-aged Korean adults with normal fundoscopic findings, following them from January 1, 2002, to February 28, 2010. Health exams were scheduled annually or biennially. At each visit, IOP was measured in both eyes using automated noncontact tonometers. The longitudinal change in IOP with age was evaluated using three-level mixed models for longitudinal paired-eye data, accounting for correlations between paired eyes and repeated measurements over time. In fully adjusted models, the average longitudinal change in IOP per 1-year increase in age was -0.065 mm Hg (95% confidence interval [CI] -0.068 to -0.063), with marked sex differences (P < 0.001). In men, the average annual IOP change was -0.093 mm Hg (95% CI -0.096 to -0.091) throughout follow-up. In women, the average annual IOP change was -0.006 mm Hg (95% CI -0.010 to -0.003), with a relatively flat association in the age range of 30 to 59 years and more marked annual decreases at younger and older ages. Intraocular pressure was inversely associated with age in a large cohort of Korean adults attending health-screening visits. For men, this inverse association was observed throughout the entire age range, while for women it was evident only in younger (<30 years of age) and older (≥60 years of age) women, with no association in women aged 30 to 59. Further research is needed to better understand the underlying mechanisms and to reconsider cutoffs for defining high IOP by age and sex groups in Asian populations.

    It is well established that pain is the most common presenting complaint in Emergency Departments. Despite great improvements in available pain management strategies, patients are left waiting for longer than 60min for pain relief on arrival to the emergency department. The aim of this study was to describe interventions that lead to successful implementation of the National Health and Medical Research Council approved guidelines Acute Pain Management: Scientific Evidence (2nd Edition) that include specific recommendations for best practice pain management. A two-phased, mixed-method, exploratory study of all 52 Australian hospital emergency departments participating in the National Emergency Care Pain Management Initiative incorporating interview and document analysis was undertaken. Interventions used by clinicians to improve pain management included nurse initiated analgesia, intranasal fentanyl for paediatric patients and lignocaine, and facio illiaca block. Education formed a major part of the intervention and the development of a working group of key stakeholders was critical in the successful implementation of change. Staff perceptions of patients' pain level and attitudes toward pain assessment and pain management were identified as barriers. This study highlighted how an effective framework to plan and implement practice change and tailored interventions, including education and training systems and products using the best available evidence, best equipped clinicians to manage pain in the ED.

    Baby Boomers are working and living longer than their pre-war counterparts, and are more likely to live in high density urban housing. This paper examines the relationship between housing type, working status and location of residence on health status in Baby Boomers. We investigated location of residence and housing type in 1009 participants of the Ageing Baby Boomers in Australia (ABBA) Study to identify any predictors of, or correlations between, these variables and health status. Current workers were less likely to report depression than retirees. We found a significantly higher rate of diabetes, obesity and hypertension in retirees than in current workers however rates of obesity, diabetes and hypertension were higher than predicted in current workers. The rates of chronic disease are higher than previous estimates and provide evidence to inform health promotion programs designed to increase physical activity and improve eating habits in baby boomers. © 2013 ACOTA.

    Full Text Available Biodiesels are a renewable energy source, and they have the potential to be used as alternatives to diesel fuel. The aim of this study is to investigate the wear and friction characteristics of Australian native first generation and second generation biodiesels using a four-ball tribo tester. The biodiesel was produced through a two-step transesterification process and characterized according to the American Society for Testing and Materials (ASTM standards. The tribological experiment was carried out at a constant 1800 rpm and different loads and temperatures. In addition, the surface morphology of the ball was tested by scanning electron microscope (SEM/energy dispersive X-ray spectroscopy (EDX analysis. The test results indicated that biodiesel fuels have a lower coefficient of frictions (COF and lower wear scar diameter (WSD up to 83.50% and 41.28%, respectively, compared to conventional diesel fuel. The worn surface area results showed that biodiesel fuel has a minimum percentage of C and O, except Fe, compared to diesel. In addition, the worn surface area for diesel was found (2.20%–27.92% to be higher than biodiesel. The findings of this study indicated that both first and second generation biodiesel fuels have better tribological performance than diesel fuel, and between the biodiesel fuels, macadamia biodiesel showed better lubrication performance.

    Farmer suicide is a major public issue in Australia. Using the psychological autopsy method, this study aimed to examine the life and death circumstances of Australian male farmers who died by suicide through verbal reports from their close significant others. Individual semistructured interviews were conducted with 12 relatives of male farmers who had died by suicide in Queensland or New South Wales, Australia (2006-2014). This study followed the COREQ checklist criteria for the reporting of qualitative research. Six interrelated themes were identified: (1) masculinity, (2) uncertainty and lack of control in farming, (3) feelings of failure in relationships and farming, (4) escalating health problems, (5) maladaptive coping, and (6) acquired capability with access to means. Effective clinical interventions, as well as suicide prevention strategies, need to consider the importance of 3 key issues in suicide among farmers: adherence to masculine norms and socialization; expectations of self in maintaining family traditions and occupation; and a male subtype of depression. © 2018 National Rural Health Association.

    One in four Australians is born overseas and 47% are either born overseas or have a parent who was. Obstetric and psychosocial risk factors for these women may differ. Data from one Sydney hospital (2012-2013) of all births recorded in the ObstetriX database were analysed (n = 3,092). Demographics, obstetric and psychosocial risk profile, obstetric interventions and complications and selected maternal and neonatal outcomes were examined for women born in Australia and overseas. Women born in Australia were younger, more likely to be primiparous (28.6 v 27.5%), be obese (32.0% v 21.4%), smoke (19.7 % v 3.0%), have an epidural (26.2% v 20.2%) and were less likely to have gestational diabetes mellitus (GDM) (6.8% v 13.7% when compared to non-Australian born women. The highest rates of GDM, Gestational Hypertension (GH) and maternal anaemia were seen in women born in China, the Philippines and Pakistan respectively. Differences were also seen in psychosocial screening between Australian and non-Australian women with Australian-born women more likely to smoke and report a mental health disorder. There was an association between having an Edinburgh Postnatal Depression Scale (EPDS) ≥ 13 and other psychosocial issues, such as thoughts of self-harm, domestic violence, childhood abuse etc. These women were also less likely to breastfeed. Women with an EPDS ≥ 13 at booking compared to women with EPDS ≤12 had a higher chance of being diagnosed with GDM (AOR 1.85 95% CI 1.14-3.0). There are significant differences in obstetric and psychosocial risk profiles and maternal and neonatal outcomes between Australian-born and non-Australian born women. In particular there appears to be an association between an EPDS of ≥13 and developing GDM, which warrants further investigation.

    2010-03-01

    This paper assesses the methodology employed in longitudinal studies of advertising and youth drinking and smoking behaviors. These studies often are given a causal interpretation in the psychology and public health literatures. Four issues are examined from the perspective of econometrics. First, specification and validation of empirical models. Second, empirical issues associated with measures of advertising receptivity and exposure. Third, potential endogeneity of receptivity and exposure variables. Fourth, sample selection bias in baseline and follow-up surveys. Longitudinal studies reviewed include 20 studies of youth drinking and 26 studies of youth smoking. Substantial shortcomings are found in the studies, which preclude a causal interpretation.

    Among working-age Australian adults with a disability, we assess the association between disability-based discrimination and both overall health and psychological distress. Using data from the 2015 Australian Bureau of Statistics Survey of Disability, Ageing and Carers we estimated the proportion of working-age women and men (15-64 years) with disability who report disability-based discrimination by socio-demographic characteristics and assessed the association between disability-based discrimination and self-reported health and psychological distress. Nearly 14% of Australians with disability reported disability-based discrimination in the previous year. Disability-based discrimination was more common among people living in more disadvantaged circumstances (unemployed, low income, lower-status occupations), younger people and people born in English-speaking countries. Disability-based discrimination was associated with higher levels of psychological distress (OR: 2.53, 95%CI: 2.11, 3.02) and poorer self-reported health (OR: 1.63, 95%CI: 1.37, 1.95). Disability-based discrimination is a prevalent, important determinant of health for Australians with disability. Implications for public health: Disability-based discrimination is an under-recognised public health problem that is likely to contribute to disability-based health inequities. Public health policy, research and practice needs to concentrate efforts on developing policy and programs that reduce discrimination experienced by Australians with disability. © 2017 The Authors.

    Although researchers have concluded that child maltreatment has a negative effect on children's learning and academic achievement, not all children are negatively affected by maltreatment, and some children seem to succeed academically despite being maltreated. Drawing on risk and resilience theory, we examined a broad range of potential risk, promotive, and protective factors within children and their environments along with characteristics of the maltreatment to account for variability in test scores. A national longitudinal probability sample of 702 maltreated school-aged children, ages 6-10, and their caregivers was used to predict reading and math scores among maltreated children over three years. We found that chronic maltreatment, poorer daily living skills, and lower intelligence explained a substantial proportion of the variance in maltreated children's math scores (39%), whereas type of maltreatment, poorer daily living skills and lower intelligence explained a substantial proportion of the variance in reading scores (54%) over time. Contrary to our prediction, having a behavior problem seemed to protect chronically maltreated children from poorer performance in math over time. To increase academic achievement among maltreated children, it is imperative that we prevent chronic maltreatment and help children increase their competency on daily living skills.

    Does religion still play a role in explorations of romance and sexuality among adolescents and young adults in a secular society such as Norway? Does it influence the type of living arrangements chosen? A population-based sample (n = 2,454) was followed longitudinally from their midteens to their late 20s using survey and register data. Christian involvement in teenage years was associated with subsequent less "precoital" exploration, less masturbation, delayed sexual intercourse, and a smaller number of sex partners. However, there were no associations with prevalence of same-sex experiences. Christians also postponed initiating romantic relationships and chose marriage over cohabitation. Associations were reduced after controlling for confounding factors but remained significant. Some associations (for example, the form of residential union chosen) were present only in the most "active" Christians. In other areas, such as "precoital explorations" and the age at which intercourse is initiated, Christian norms seem to play a role in much broader segments of the population. The findings indicate that Christianity may continue to influence young Norwegians' experiences of sexuality and cohabitation more than has been expected.

    Background There are an increasing number of children in Australia growing up with same-sex attracted parents. Although children from same-sex parent families do in general perform well on many psychosocial measures recent research is beginning to consider some small but significant differences when these children are compared with children from other family backgrounds. In particular studies suggest that there is an association between the stigma that same-sex parent families experience and child wellbeing. Research to date lacks a holistic view with the complete physical, mental and social wellbeing of children not yet addressed. In addition, most studies have focused only on families with lesbian parents and have studied only small numbers of children. Methods/design The Australian Study of Child Health in Same-Sex Families (ACHESS) is a national study that aims to determine the complete physical, mental and social wellbeing of Australian children under the age 18 years with at least one parent who self identifies as being same-sex attracted. There will be a particular focus on the impact that stigma and discrimination has on these families. Parent and child surveys will be used to collect data and will be available both online and in paper form. Measures have been chosen whenever possible that have sound conceptual underpinnings, robust psychometric properties and Australian normative data, and include the Child Health Questionnaire (CHQ), the Strengths and Difficulties Questionnaire (SDQ) and the Kessler Psychological Distress Scale (K10). Discussion ACHESS aims to be the largest study of its kind and will for the first time produce a detailed quantitative analysis of Australian children with same-sex attracted parents.

    Full Text Available Botanical illustration combines scientific knowledge and artistic technique. However, whereas illustrated botanical images record static visual qualities, such as form and color, written botanical narratives supply crucial sensory, ecological, historical, and cultural contexts that complement visual representation. Understanding the text-image interface—where images and words intersect—contributes to humanities-based analyses of botanical illustration and illustrators. More specifically, a process philosophy perspective reveals the extent to which botanical representations engage the temporality, cyclicality, and contextuality of the living plants being illustrated. This article takes up these themes through a comparative theoretical study of three female Western Australian botanical illustrators, Georgiana Leake (1812–1869, Emily Pelloe (1877–1941, and Philippa Nikulinsky (born 1942, whose lives together span the 183 year history of the Swan River Colony and the state of Western Australia. I apply a processist framework to examine the text-image interface of their works. All three illustrators use some form of textuality: marginalia, annotations, written accompaniments, introductory statements, and other narrative materials. In examining their written commentaries and traces, I identify the emergence of a process mode of botanical illustration that represents plants as ecological, historical, cultural, and temporal organisms.

    Purpose: This paper presents the results of a study undertaken to investigate how Australian radiation therapists define fitness to practise. Method: A qualitative approach was taken to data collection with focus groups being employed to gather the data. Analysis was informed by grounded theory. Following ethics approval, three homogeneous focus groups were conducted comprising a total of 21 participants, with 5-8 participants per group. The discussions were transcribed, verified by the researcher and participants, then unitised, coded and a sample checked by a second coder. Findings: There was no consensus on the definition of fitness to practise. The terms professionalism and competence were used interchangeably in some definitions. Four themes emerged from the data, these were; fitness as a continuum (individual differences and longevity in the profession), fitness as behaviour and conduct (professionalism and competence), fitness as a state of mind (attitudes and intangible elements) and fitness as being qualified (course completion means fitness to practise). Three concepts which were not raised were illegal behaviour, impaired practice and dose errors. Conclusion: There is no consensus among radiation therapists about fitness to practise. There was confusion with how Fitness to practise relates to professionalism and competence with little mention of how impairment is interwoven into the notion of fitness to practise. Without an unambiguous definition and robust criteria, making the 'judgement call' as to whether a practitioners' fitness to practise is impaired will continue to be a challenge for educators, departmental managers and registration boards.

    Full Text Available Many healthy adult cats are euthanised annually in shelters, and novel approaches are required to reduce euthanasia rates. Waiving adoption fees is one such approach. However, concerns that less responsible owners will be attracted to free events persist among welfare groups. We evaluated evidence for differences in cat fate, health, and adherence to husbandry legislation via a case-study of a free adoption-drive for cats ≥1 year at a Western Australian shelter. Post-adoption outcomes were compared between free adopters and a control group of normal-fee adopters. The free adoption-drive rehomed 137 cats, increasing average weekly adoptions by 533%. First-time adopters were a significantly larger portion of the free cohort, as a result of mixed-media promotions. Both adopter groups selected cats of similar age; sex and pelage. Post-adoption, both groups retained >90% cats, reporting near identical incidences of medical and behavioural problems. Adopters did not differ in legislative compliance regarding fitting collars, registering cats, or allowing cats to roam. The shelter reported satisfaction with the adoption-drive, because in addition to relieving crowding of healthy adults, adoption of full-fee kittens increased 381%. Overall, we found no evidence for adverse outcomes associated with free adoptions. Shelters should not be dissuaded from occasional free adoption-drives during overflow periods.

    Managing staff stress and preventing long-term burnout in oncology staff are highly important for both staff and patient well-being. Research addressing work-related stress in adult oncology is well documented; however, less is known about this topic in the pediatric context. This study examined sources of work-related stress and reward specific to multidisciplinary staff working in pediatric oncology in Australia. Participants were 107 pediatric oncology clinicians, including medical, nursing, and allied health staff from two Australian pediatric oncology centers. Participants completed an online survey using two newly developed measures: the work stressors scale-pediatric oncology and the work rewards scale-pediatric oncology. The most commonly reported sources of both stress and reward are related to patient care and interactions with children. Results indicated that levels of work-related stress and reward were similar between the professional disciplines and between the two hospitals. Regression analyses revealed no demographic or organizational factors that were associated with either stress or reward. Work-related stress and reward are not mutually exclusive; particular situations and events can be simultaneously stressful and rewarding for healthcare providers. Although patient care and interactions with children was found to be the most stressful aspect of working in this speciality, it was also the greatest source of reward. Results are discussed in relation to workplace approaches to staff well-being and stress reduction. Copyright © 2015 John Wiley & Sons, Ltd.

  12. The discourse of "social licence to operate": case study of the Australian wind industry

    Full Text Available Social Licence to Operate is a concept from the mining industry that reflects the ongoing acceptance or approval for a development granted by local stakeholders. It is now being applied by wind farm developers. Using the Australian wind industry as a case study, this discourse analysis examined how Social Licence to Operate is perceived and operationalised, and the key themes in this conceptual and applied discourse. Discourse analysis acknowledges that language choices are not accidental and discourse reflects power relationships. The wind industry representatives interviewed considered power over the Social Licence to Operate was shared with community stakeholders. They recognised the stakeholders' power to delay or prevent projects, but rejected the notion that every stakeholder group should have veto power. Social Licence to Operate is seen by the wind industry through a business-oriented perspective, with an emphasis on business risk, and they describe the opposition to wind farms by invoking a metaphor of "battle". The industry respondents described Social Licence to Operate as incorporating the values of trust, transparency and participation—which all contribute to creating "authentic" relationships. These findings can inform Social Licence to Operate research, engagement practices, and also encourage reflection by industry representatives on their implicit intentions for stakeholder engagement.

    To explore perceptions of dietary recommendations for fruit and vegetables, and barriers and opportunities for increasing consumption. Qualitative study with an experiential component. Older adults' households. Six focus groups with 38 Australian adults aged 50 to 64 years who reported low vegetable consumption. Week 1: focus group including demonstration of recommended fruit and vegetable servings; week 2: delivery of a week's supply of fruit and vegetables and recipes; week 3: follow-up focus group. Perceptions of a healthful diet, fruit and vegetable recommendations, barriers to consumption, and reactions to the food delivery and recipes. Qualitative, thematic analysis. Participants were unfamiliar with serving recommendations. Barriers to consumption were as follows: perceptions that vegetables are eaten only with evening meals, preference for eating meat, believing that recommended quantities were too big, and a lack of preparation time. The delivery had a positive impact on some (especially low fruit consumers), for whom the availability of appealing fruit served as a prompt for consumption. Possible strategies for enabling consumers to achieve adequate fruit and vegetable consumption are education about the recommended number and size of servings and distribution of fruit and vegetables relative to meat and carbohydrates, encouragement to spread fruit and vegetable consumption over the day, and promoting the appealing sensory attributes of fruit and vegetables.

  14. Online Education Systems in Scandinavian and Australian Universities: A Comparative Study

    Full Text Available This article presents a comparative study of online education systems in Norwegian, Swedish, and Australian universities. The online education systems discussed comprise content creation tools and systems for learning management, student management, and accounting. The author of this article arrives at the conclusion that there seems to be a general lack of integration between theses systems in all three countries. Further, there seems to be little focus on standards specifications such as IMS Global Learning Consortium (IMS and Sharable Content Object Reference Model (SCORM in higher education in all three countries. It was found that both Norway and Sweden value the importance of nationally developed learning management systems and student management systems; however, this does not seem to be the case in Australia. There also seems to be much more national coordination and governmental coercion concerning the choice of student management systems used in Sweden and Norway, than is the case in Australia. Finally, with regard to online education, the most striking difference between these three countries is that of economic policy. In Australia, education is considered an important export industry. In Norway and Sweden, however, the export of education does not seem to be an issue for public discussion.

  15. Nutrition Education in Australian Midwifery Programmes: A Mixed-Methods Study

    Full Text Available Little research has explored how nutrition content in midwifery education prepares midwives to provide prenatal nutrition advice. This study examined the nature and extent of nutrition education provided in Australian midwifery programmes. A mixed-methods approach was used, incorporating an online survey and telephone interviews. The survey analysis included 23 course coordinators representing 24 of 50 accredited midwifery programmes in 2012. Overall, the coordinators considered nutrition in midwifery curricula and the midwife’s role as important. All programmes included nutrition content; however, eleven had only 5 to <10 hours allocated to nutrition, while two had a designated unit. Various topics were covered. Dietitians/other nutrition experts were rarely involved in teaching or reviewing the nutrition content. Interviews with seven coordinators revealed that nutrition education tended to be problem-oriented and at times based on various assumptions. Nutrition content was not informed by professional or theoretical models. The development of nutrition assessment skills or practical training for midwifery students in providing nutrition advice was lacking. As nutrition is essential for maternal and foetal health, nutrition education in midwifery programmes needs to be reviewed and minimum requirements should be included to improve midwives’ effectiveness in this area. This may require collaboration between nutrition experts and midwifery bodies.

    Up to 80% of residents in aged care facilities (ACFs) experience pain, which is often suboptimally managed. To characterize pain management in ACFs and identify the barriers to optimal pain management. An exploratory descriptive qualitative study using semistructured interviews. Five Southern Tasmania, Australian ACFs. 23 staff members (18 nurses and 5 facility managers). Interviews were conducted from September to November 2015. Interviews included questions about how pain was measured or assessed, what happened if pain was identified, barriers to pain management, and potential ways to overcome these barriers. Interviewees noted that there were no formal requirements regarding pain assessment at the ACFs reviewed; however, pain was often informally assessed. Staff noted the importance of adequate pain management for the residents' quality of life and employed both nonpharmacologic and pharmacologic techniques to reduce pain when identified. The barriers to optimal pain management included difficulty identifying and assessing pain, residents' resistance to reporting pain and/or taking medications, and communication barriers between the nursing staff and GPs. Staff interviewed were dedicated to managing residents' pain effectively; however, actions in a number of areas could improve resident outcomes. These include a more consistent approach to documenting pain in residents' progress notes and improving nurse-GP communications to ensure that new or escalating pain is identified and expedient changes can be made to the resident's management. Additionally, resident, family, nurse, and carer education, conducted within the facilities on a regular basis, could help improve the pain management of residents. Copyright © 2017.

    Full Text Available           Democracies around the world now face Citizen-apathy. This is a concern now more than ever faced by countries around the globe. eGovernment is undoubtedly a platform to deliberate and enable citizens regain confidence and faith in democratic  processes. Citizens now seek Verifiable, Open, Transparent, Empathetic, Responsive and Sensitive Electronic Democracy and Government (VOTERS EDG, Karna, 2012. Similar to corporate world, there are voices stressing on govenments for the need to understand the stakeholders, their involvement, relationships and responsibilities of a state in eGovernance. Citizens everywhere now demand Verifiable, Open, Transparent, Empathetic, Responsive and Sensitive Electronically Democratic Government as a State Social Responsibity (SSR. Peoples movements and outbursts against authorities with the help of Word of Mouse (Karna, 2012 have established that transparent and open governance is the need of the hour. This paper presents findings of the study conducted in an Australian City Council for preparing the city council for ‘City e-readiness’ to initiate e-Government activities. We propose the idea of ‘Centrality of Citizens’ in context of eGovernment. We further build upon the original concept of deeming eGovernment as ‘State Social Responsibility’ (SSR (Karna, 2010, by governments at all levels.

    Multi-organ procurement surgical procedures through the generosity of deceased organ donors, have made an enormous impact on extending the lives of recipients. There is a dearth of in-depth knowledge relating to the experiences of perioperative nurses working closely with organ donors undergoing multi-organ procurement surgical procedures. The aim of this study was to address this gap by describing the perioperative nurses experiences of participating in multi-organ procurement surgical procedures and interpreting these findings as a substantive theory. This qualitative study used grounded theory methodology to generate a substantive theory of the experiences of perioperative nurses participating in multi-organ procurement surgery. Recruitment of participants took place after the study was advertised via a professional newsletter and journal. The study was conducted with participants from metropolitan, rural and regional areas of two Australian states; New South Wales and Western Australia. Thirty five perioperative nurse participants with three to 39 years of professional nursing experience informed the study. Semi structured in-depth interviews were undertaken from July 2009 to April 2010 with a mean interview time of 60 min. Interview data was transcribed verbatim and analysed using the constant comparative method. The study results draw attention to the complexities that exist for perioperative nurses when participating in multi-organ procurement surgical procedures reporting a basic social psychological problem articulated as hiding behind a mask and how they resolved this problem by the basic social psychological process of finding meaning. This study provides a greater understanding of how these surgical procedures impact on perioperative nurses by providing a substantive theory of this experience. The findings have the potential to guide further research into this challenging area of nursing practice with implications for clinical initiatives, management

    Full Text Available Abstract Background In 1987, a prospective study of an Australian Aboriginal Birth Cohort was established focusing on the relationships of fetal and childhood growth with the risk of chronic adult disease. However as the study is being conducted in a highly marginalized population it is also an important resource for cross-sectional descriptive and analytical studies. The aim of this paper is to describe the processes of the third follow up which was conducted 20 years after recruitment at birth. Methods Progressive steps in a multiphase protocol were used for tracing, with modifications for the expected rural or urban location of the participants. Results Of the original 686 cohort participants recruited 68 were untraced and 27 were known to have died. Of the 591 available for examination 122 were not examined; 11 of these were refusals and the remainder were not seen for logistical reasons relating to inclement weather, mobility of participants and single participants living in very remote locations. Conclusion The high retention rate of this follow-up 20 years after birth recruitment is a testament to the development of successful multiphase protocols aimed at overcoming the challenges of tracing a cohort over a widespread remote area and also to the perseverance of the study personnel. We also interpret the high retention rate as a reflection of the good will of the wider Aboriginal community towards this study and that researchers interactions with the community were positive. The continued follow-up of this life course study now seems feasible and there are plans to trace and reexamine the cohort at age 25 years.
