Purpose Environmental changes are potentially effective population-level physical activity (PA) promotion strategies. However, robust multi-site evidence to guide international action for developing activity-supportive environments is lacking. We estimated pooled associations of perceived environmental attributes with objectively-measured PA outcomes; between-site differences in such associations; and, the extent to which perceived environmental attributes explain between-site differences in PA. Methods This was a cross-sectional study conducted in 16 cities located in Belgium, Brazil, Colombia, Czech Republic, Denmark, China, Mexico, New Zealand, Spain, United Kingdom, and USA. Participants were 6,968 adults residing in administrative units stratified by socio-economic status and transport-related walkability. Predictors were 10 perceived neighborhood environmental attributes. Outcome measures were accelerometry-assessed weekly minutes of moderate-to-vigorous PA (MVPA) and meeting the PA guidelines for cancer/weight gain prevention (420 min/week of MVPA). Results Most perceived neighborhood attributes were positively associated with the PA outcomes in the pooled, site-adjusted, single-predictor models. Associations were generalizable across geographical locations. Aesthetics and land use mix – access were significant predictors of both PA outcomes in the fully-adjusted models. Environmental attributes accounted for within-site variability in MVPA corresponding to a 3 min/d or 21 min/week standard deviation. Large between-site differences in PA outcomes were observed: 15.9% to 16.8% of these differences were explained by perceived environmental attributes. All neighborhood attributes were associated with between-site differences in the total effects of the perceived environment on PA outcomes. Conclusions Residents’ perceptions of neighborhood attributes that facilitate walking were positively associated with objectively-measured MVPA and meeting the guidelines

Sedentary behavior and physical inactivity are significant contributors to youth obesity in the United States. Neighborhood dog walking is an outlet for physical activity (PA). Therefore, understanding the relationship between built environment, dog ownership, and youth PA is essential. This study examined the influence of dog ownership and parental built environment perceptions on children's PA in the Washington, D.C. area. In 2014, questionnaires were mailed to 2000 parents to assess family dog ownership; children's outdoor dog walking or playing; and parental perceived built environment measures. Chi-square analyses examined differences in parental perceived built environment measures between children with and without family dogs. The sample included 144 children (50% female; average-age 9.7 years; 56.3% White; 23.7% African-American; 10.4% Asian-American; 29.9% owned dog). Only 13% and 5.6% of the children walked or played outdoors with the dog daily, respectively. A significantly greater proportion ( p -value supports children's outdoor PA through dog walking and playing.

Physical activity (PA) attenuates chronic stress and age-related and cardiovascular disease risks, whereby potentially slowing telomere shortening. We aimed to study the association between seven-day objectively measured habitual PA, chronic stress and leukocyte telomere length. Study participants were African (N.=96) and Caucasian (N.=107) school teachers of the Sympathetic activity and Ambulatory Blood Pressure in Africans study. All lifestyle characteristics (including PA) were objectively measured. The general health questionnaire and serum cortisol were assessed as psychological and physical measures of chronic stress. Leukocyte telomere length was measured using the quantitative real-time polymerase chain reaction. Africans had significantly shorter telomeres (Pstress or telomere length. However, more time spent with light intensity PA time was significantly and independently correlated with lower waist circumference (r=-0.21, P=0.004); in turn, greater waist circumference was significantly associated shorter telomeres (β=-0.17 [-0.30, -0.03], P=0.017). Habitual PA of different intensity was not directly associated with markers of chronic stress and leukocyte telomere length in this biethnic cohort. However, our findings suggest that light intensity PA could contribute to lowered age-related disease risk and healthy ageing by facilitating maintenance of a normal waist circumference.

Full Text Available Little is known about the extent that different domains contribute to total sedentary (SED, light (LPA and moderate-to-vigorous physical activity (MVPA. We aimed to identify domain-specific physical activity (PA patterns in school-aged children who were assessed by questionnaire and accelerometry. For the study, 298 German school children and adolescents aged 6–17 years wore an accelerometer for one week and completed a PA recall-questionnaire for the same period. Spearman coefficients (r were used to evaluate the agreement between self-reported and objectively measured PA in five domains (transport, school hours, physical education, leisure-time, organized sports activities. School hours mainly contributed to the total objectively measured SED, LPA and MVPA (55%, 53% and 46%, respectively, whilst sports activities contributed only 24% to total MVPA. Compared to accelerometry, the proportion of self-reported LPA and MVPA during school hours was substantially underestimated but overestimated during leisure-time. The agreement of self-reported and objectively measured PA was low for total LPA (r = 0.09, 95% CI (confidence interval: −0.03–0.20 and total MVPA (r = 0.21, 95% CI: 0.10–0.32, while moderate agreement was only found for total SED (r = 0.44, 95% CI: 0.34–0.53, LPA during transport (r = 0.59; 95% CI: 0.49–0.67 and MVPA during organized sports activities (r = 0.54; 95% CI: 0.38–0.67. Since school hours mainly contribute to total SED, LPA and MVPA and self-reported LPA and MVPA during school were importantly underestimated compared to objectively measured LPA and MVPA, the application of objective measurements is compulsory to characterize the entire activity pattern of school-aged children.

Both clinicians and forensic practitioners should distinguish parental alienation (rejection of a parent without legitimate justification) from other reasons for contact refusal. Alienated children-who were not abused-often engage in splitting and lack ambivalence with respect to the rejected parent; children who were maltreated usually perceive the abusive parent in an ambivalent manner. The purpose of this study was to assess the usefulness of the Parental Acceptance-Rejection Questionnaire (PARQ) in identifying and quantifying the degree of splitting, which may assist in diagnosing parental alienation. Results showed that severely alienated children engaged in a high level of splitting, by perceiving the preferred parent in extremely positive terms and the rejected parent in extremely negative terms. Splitting was not manifested by the children in other family groups. The PARQ may be useful for both clinicians and forensic practitioners in evaluating children of divorced parents when there is a concern about the possible diagnosis of parental alienation. © 2017 American Academy of Forensic Sciences.

Latino preschoolers (3-5 year old children) have among the highest rates of obesity. Low levels of physical activity (PA) are a risk factor for obesity. Characterizing what Latino parents do to encourage or discourage their preschooler to be physically active can help inform interventions to increase their PA. The objective was therefore to develop and assess the psychometrics of a new instrument: the Preschooler Physical Activity Parenting Practices (PPAPP) among a Latino sample, to assess parenting practices used to encourage or discourage PA among preschool-aged children. Cross-sectional study of 240 Latino parents who reported the frequency of using PA parenting practices. 95% of respondents were mothers; 42% had more than a high school education. Child mean age was 4.5 (±0.9) years (52% male). Test-retest reliability was assessed in 20%, 2 weeks later. We assessed the fit of a priori models using Confirmatory factor analyses (CFA). In a separate sub-sample (35%), preschool-aged children wore accelerometers to assess associations with their PA and PPAPP subscales. The a-priori models showed poor fit to the data. A modified factor structure for encouraging PPAPP had one multiple-item scale: engagement (15 items), and two single-items (have outdoor toys; not enroll in sport-reverse coded). The final factor structure for discouraging PPAPP had 4 subscales: promote inactive transport (3 items), promote screen time (3 items), psychological control (4 items) and restricting for safety (4 items). Test-retest reliability (ICC) for the two scales ranged from 0.56-0.85. Cronbach's alphas ranged from 0.5-0.9. Several sub-factors correlated in the expected direction with children's objectively measured PA. The final models for encouraging and discouraging PPAPP had moderate to good fit, with moderate to excellent test-retest reliabilities. The PPAPP should be further evaluated to better assess its associations with children's PA and offers a new tool for measuring PPAPP

Full Text Available Abstract Background Lifetime physical activity energy expenditure (PAEE is an important determinant of risk for many chronic diseases but remains challenging to measure. Previously reported historical physical activity (PA questionnaires appear to be reliable, but their validity is less well established. Methods We sought to design and validate an historical adulthood PA questionnaire (HAPAQ against objective PA measurements from the same individuals. We recruited from a population-based cohort in Cambridgeshire, UK, (Medical Research Council Ely Study in whom PA measurements, using individually calibrated heart rate monitoring, had been obtained in the past, once between 1994 and 1996 and once between 2000 and 2002. 100 individuals from this cohort attended for interview. Historical PA within the domains of home, work, transport, sport and exercise was recalled using the questionnaire by asking closed questions repeated for several discrete time periods from the age of 20 years old to their current age. The average PAEE from the 2 periods of objective measurements was compared to the self-reported data from the corresponding time periods in the questionnaire. Results Significant correlations were observed between HAPAQ-derived and objectively measured total PAEE for both time periods (Spearman r = 0.44; P Conclusions HAPAQ demonstrates convergent validity for total PAEE and vigorous PA. This instrument will be useful for ranking individuals according to their past PA in studies of chronic disease aetiology, where activity may be an important underlying factor contributing to disease pathogenesis.

Limited self-report data suggest that South Asian (SA) women fail to meet physical activity (PA) recommendations. Recent research using objective measures reveals SA women living in the UK have higher PA levels than previously reported, and a pattern of under-reporting PA and sedentary time (ST). There is limited research on SA women's understanding and experiences of PA/ST, and the cultural contexts and conditions within which they occur. Therefore the aims of this mixed-methods study were to compare perceived PA and ST to objectively measured data and explore PA- and ST-specific contexts, experiences, and sources of PA and ST amongst SA women in the UK. 24 women were purposively sampled to participate in a semi-structured interview from a larger study of 140 women who wore an accelerometer for 7 days. Demographic and anthropometric data were also collected. Notable qualitative themes on contextualisation were of adequate PA as "keeping busy" or "being healthy", and of ST as "lazy" or "resting in old age". Few participants reported being sedentary, and most believed they were sufficiently physically active. Objectively measured PA/ST indicated that 66% women were less active than perceived (with regard to duration and intensity), with none able to estimate duration of ST. Findings suggest that overall, SA women have contextualisations of PA/ST that may not coincide with those of researchers, health professionals and policy makers, and lack awareness of the intensity of PA in which they engage and the health risks of high levels of ST. These findings highlight the need for objective measures of PA and ST in this population combined with in-depth qualitative assessments to provide more accurate assessments of these behaviours. This information can subsequently be used to develop health promotion messages and interventions focusing on increasing duration and/or intensity levels of daily activities (e.g., walking, housework) and reducing ST in this population.

Objective: To examine relationships between parenting styles and practices and child moderate-to-vigorous physical activity (MVPA) and screen time. Methods: Participants were children (6.9 ± 1.8 years) with a body mass index in the 70–95th percentile and their parents (421 dyads). Parent-completed questionnaires assessed parental support for child physical activity (PA), parenting styles and child screen time. Children wore accelerometers to assess MVPA. Results: Parenting style did not predict MVPA, but support for PA did (positive association). The association between support and MVPA, moreover, varied as a function of permissive parenting. For parents high in permissiveness, the association was positive (greater support was related to greater MVPA and therefore protective). For parents low in permissiveness, the association was neutral; support did not matter. Authoritarian and permissive parenting styles were both associated with greater screen time. Conclusions: Parenting practices and styles should be considered jointly, offering implications for tailored interventions.

The risk of obesity is reduced when youth engage in recommended levels of physical activity (PA). For that reason, public health organizations in the U.S. have encouraged communities to implement programs and policies designed to increase PA in youth, and many communities have taken on that challenge. However, the long-term effects of those programs and policies on obesity are largely unknown. The Healthy Communities Study is a large-scale observational study of U.S. communities that is examining the characteristics of programs and policies designed to promote healthy behaviors (e.g., increase PA and improve diet) and determining their association with obesity-related outcomes. The purpose of this paper is to describe the methods used to measure PA in children and the personal and community factors that may influence it. The study used both self-reported and objective measures of PA, and measured personal, family, and home influences on PA via three constructs: (1) PA self-schema; (2) parental support; and (3) parental rules regarding PA. Neighborhood and community factors related to PA were assessed using three measures: (1) child perceptions of the neighborhood environment; (2) availability of PA equipment; and (3) attributes of the child's street segment via direct observation. School influences on children's PA were assessed via three constructs: (1) school PA policies; (2) child perceptions of the school PA environment; and (3) school outdoor PA environment. These measures will enable examination of the associations between characteristics of community PA programs and policies and obesity-related outcomes in children and youth.

This study aimed to assess the psychometric properties of a child-report, multidimensional measure of physical activity (PA) parenting, the Activity Support Scale for Multiple Groups (ACTS-MG), in African American and non-Hispanic white families. The ACTS-MG was administered to children aged 5 to 12 years. A three factor model of PA parenting (Modeling of PA, Logistic Support, and Restricting Access to Screen-based Activities) was tested separately for mother's and fathers' PA parenting. The proposed three-factor structure was supported in both racial groups for mothers' PA parenting and in the African American sample for fathers' PA parenting. Factorial invariance between racial groups was demonstrated for mother's PA parenting. Building on a previous study examining the ACTS-MG parent-report, this study supports the use of the ACTS-MG child-report for mothers' PA parenting. However, further research is required to investigate the measurement of fathers' PA parenting across racial groups.

Full Text Available Although physical activity (PA is an important and modifiable determinant of health, in Sweden only 15% of boys and 10% of girls aged 15 years old achieve the recommended levels of PA 7 days per week. Adolescents’ PA levels are associated with social influence exerted by parents, friends, and teachers. The purpose of this study was to describe parents’ experiences of being a part of their adolescents’ empowerment-inspired PA intervention. A qualitative interview study was performed at a school in the northern part of Sweden. A total of 10 parents were interviewed, and the collected data were analyzed with qualitative content analysis. Three subthemes were combined into one main theme, demonstrating that parents are one important part of a successful PA intervention. The life of an adolescent has many options and demands that make it difficult to prioritize PA. Although parents felt that they were important in supporting their adolescent, a successful PA intervention must have multiple components. Moreover, the parents noted that the intervention had a positive effect upon not only their adolescents’, but also their own PA. Interventions aimed at promoting PA among adolescents should include measures to stimulate parent participation, have an empowerment approach, and preferably be school-based.

The ToyBox-study developed an evidence- and theory-based intervention to improve preschoolers' energy balance-related behaviours - including physical activity (PA) - by targeting the kindergarten environment and involving their parents/caregivers. The present study aimed to examine the effect of the ToyBox-intervention on increasing Belgian preschoolers' objectively measured PA levels. A sample of 472 preschoolers (4.43 ± 0.55 years; 55.1% boys) from 27 kindergartens (15 intervention, 12 control kindergartens) in Flanders, Belgium were included in the data analyses. Preschoolers wore an ActiGraph accelerometer for six consecutive days and were included in the data analyses if they had a minimum of two weekdays and one weekend day, both at baseline and follow-up (one year later). Preschoolers' PA outcomes were estimated for an average day, weekday, weekend day, during school hours, and during after school hours. To assess intervention effects, multilevel repeated measures analyses were conducted for the total sample, and for sub-groups (according to sex, kindergarten levels of socio-economic status (SES) and risk groups (low levels of PA at baseline)) of preschoolers. Small intervention effects were found in the total sample. Most intervention effects were found in boys and in preschoolers from high SES kindergartens. Boys from the intervention group had an increase in vigorous PA (ß=1.47, p=0.03) and moderate-to-vigorous PA (ß=1.27, p=0.03) from baseline to follow-up, whereas PA levels in boys from the control group stagnated or decreased. In preschoolers from high SES kindergartens, the largest effects were found for PA outcomes during school hours and during after school hours. The results from the Belgian sample demonstrate that effects of the PA-component of the ToyBox-intervention on objectively measured PA were found in preschool boys and in preschoolers from high SES kindergartens, which means that the ToyBox-intervention was mainly effective in those sub

Physical activity (PA) is suggested to contribute to fat loss not only through increasing energy expenditure "per se" but also increasing muscle mass; therefore, it would be interesting to better understand the specific associations of PA with the different body's components such as fat mass and muscle mass. The aim of the present study was to examine the association between objectively measured PA and indices of fat mass and muscle components independently of each other giving, at the same time, gender-specific information in a wide cohort of European adolescents. A cross-sectional study in a school setting was conducted in 2200 (1016 males) adolescents (14.7 ± 1.2 years). Weight, height, skinfold thickness, bioimpedance and PA (accelerometry) were measured. Indices of fat mass (body mass index, % fat mass, sum of skinfolds) and muscular component (assessed as fat-free mass) were calculated. Multiple regression analyses were performed adjusting for several confounders including fat-free mass and fat mass when possible. Vigorous PA was positively associated with height (pgenders, except for average PA in relation with body mass index in females. Regarding muscular components, vigorous PA showed positive associations with fat-free mass and muscle mass (all pgenders. Average PA was positively associated with fat-free mass (both p<0.05) in males and females. The present study suggests that PA, especially vigorous PA, is negatively associated with indices of fat mass and positively associated with markers of muscle mass, after adjusting for several confounders (including indices of fat mass and muscle mass when possible). Future studies should focus not only on the classical relationship between PA and fat mass, but also on PA and muscular components, analyzing the independent role of both with the different PA intensities.

Full Text Available Abstract Background Regular physical activity (PA confers many positive effects on health and well-being. Sedentary behavior (SB, in turn, is a risk factor for health, regardless of the level of moderate to vigorous PA. The present study describes the levels of objectively measured SB, breaks in SB, standing still and PA among Finnish adults. Methods This cross-sectional analysis is based on the sub-sample of the population-based Health 2011 Study of Finnish adults. The study population consisted of 18-to-85-year old men and women who wore a waist-worn triaxial accelerometer (Hookie AM 20 for at least 4 days, for at least 10 h per day (n = 1587 during a week. PA and SB were objectively assessed from the raw accelerometric data using novel processing and analysis algorithms with mean amplitude deviation as the processing method. The data was statistically analyzed using cross-tabulations, analysis of variance and analysis of covariance. Results The participants were on average 52 years old, 57 % being women. Participants were sedentary 59 % of their waking wear time, mainly sitting. They spent 17 % of the time standing still, 15 % in light intensity PA, 9 % in moderate PA and less than 1 % in vigorous PA. Participants aged 30–39 years had the highest number of breaks in SB per day. Younger participants (<30 years of age had more moderate and vigorous PA than older ones (≥60 years of age, and 30–60-year-olds had the greatest amount of light PA. Conclusions Participants spent nearly 60 % of their waking time sedentary, and the majority of their daily PA was light. From a public health perspective it is important to find effective ways to decrease SB as well as to increase the level of PA. Our analysis method of raw accelerometer data may allow more precise assessment of dose-response relationships between objectively measured PA and SB and various indicators of health and well-being.

Chronic widespread pain (CWP) is a common and potentially debilitating disorder. Patterns of physical activity (PA) in adults with CWP have primarily been investigated using subjective, self-report measures. The current study sought to characterize PA among community-dwelling individuals with CWP, chronic regional pain, or no chronic pain using objective measurements obtained via accelerometry in the 2003 to 2004 National Health and Nutrition Examination Survey. Data from 3,952 participants ages 20 and older were analyzed to assess relationships between pain status and objective measurements of PA. Prevalence of CWP was 3.3% and 5.4% in men and women, respectively. In men and women, the average activity counts per minute and time spent in moderate-to-vigorous PA were significantly lower for the CWP group than for the no chronic pain group. Interestingly, time spent in sedentary, light, and lifestyle activities was not associated with pain status. Statistical interaction tests indicated that the effects of chronic pain on counts per minute were stronger in men than in women. Despite recommendations for increased moderate-to-vigorous PA as a pain management strategy for CWP, results from this nationally representative study indicate that adults with CWP participate in less moderate-to-vigorous PA than individuals without chronic pain. Using objective measurement of PA in a nationally representative sample, this study demonstrates that adults with CWP participate in reduced daily and moderate-to-vigorous PA in comparison to people with no chronic pain. Findings indicate that clinicians should emphasize the importance of increasing PA in patients with CWP. Copyright © 2014 American Pain Society. Published by Elsevier Inc. All rights reserved.

The health benefits of exercise are clear. In targeting interventions it would be valuable to know whether characteristic patterns of physical activity (PA) are associated with particular population subgroups. The present study used cluster analysis to identify characteristic hourly PA patterns measured by accelerometer. Cross-sectional design. Objectively measured PA in Hong Kong adults. Four-day accelerometer data were collected during 2009 to 2011 for 1714 participants in Hong Kong (mean age 44?2 years, 45?9% male). Two clusters were identified, one more active than the other. The ‘active cluster’ (n 480) was characterized by a routine PA pattern on weekdays and a more active and varied pattern on weekends; the other, the ‘less active cluster’ (n 1234), by a consistently low PA pattern on both weekdays and weekends with little variation from day to day. Demographic, lifestyle, PA level and health characteristics of the two clusters were compared. They differed in age, sex, smoking, income and level of PA required at work. The odds of having any chronic health conditions was lower for the active group (adjusted OR50?62, 95% CI 0?46, 0?84) but the two groups did not differ in terms of specific chronic health conditions or obesity. Implications are drawn for targeting exercise promotion programmes at the population level.

This cross sectional study aims to determine the effects of gender and parental perception of safety at school on children's physical activity (PA) levels. Parents of school aged Mexican children residing in Guadalajara, Mexico City, and Puerto Vallarta, completed surveys about their children's PA measures. The physical activity indicators were evaluated using linear and logistical regression models. Analysis did not indicate that gender moderated the relationship between parental perception of safety and PA measures, but significant gender issues exist with girls participating less than boys in the three measures of PA in this study (p<0.001). Results suggest the need for additional interventions promoting physical activity in girls in Mexico.

Background. Food allergy is related to poorer quality of life (QoL) and mental health of caregivers. Many parents diagnose food allergy in their child without seeking medical care and there is limited research on this group. This study investigated parental QoL and mental health in parents of children with parent-diagnosed food allergy (PA), medically diagnosed food allergy (MA), and a control group with no allergy (NA). Methods. One hundred and fifty parents from a general population completed validated measures of QoL, anxiety, depression, and stress. Results. Parents of children with food allergy (PA or MA) reported higher stress, anxiety, and depression than the control group (all p food allergy related QoL compared to parents of children with PA (p food allergy have significantly poorer mental health compared to healthy controls, irrespective of whether food allergy is medically diagnosed or not. It is important to encourage parents to have their child medically tested for food allergy and to recognise and refer for psychological support where needed.

Full Text Available Parents play a crucial role in the development of their children’s lifestyle and health behaviour. This study aims to examine associations between parental physical activity (PA and children’s BMI percentiles (BMIPCT, moderate to vigorous PA (MVPA as well as participation in organised sports. Height and body weight was measured in 1615 in German children (7.1 ± 0.6 years, 50.3% male and converted to BMIPCT. Parental BMI was calculated based on self-reported height and body weight. Children’s MVPA and sports participation as well as parental PA were assessed via parental questionnaire. Analysis of covariance (ANCOVA, controlling for age and family income was used to examine the association between parental and children’s PA levels as well as BMIPCT. 39.7% of the parents classified themselves as physically active and 8.3% of children were classified as overweight or obese. Lower BMIPCT were observed with both parents being physically active (44.5 ± 26.3 vs. 50.2 ± 26.9 and 52.0 ± 28.4, respectively. There was no association between parental and children’s PA levels but children with at least one active parent displayed a higher participation in organised sports (102.0 ± 96.6 and 117.7 ± 123.6 vs. 73.7 ± 100.0, respectively. Children of active parents were less likely to be overweight and obese. The lack of association between subjectively assessed parental PA and child MVPA suggests that parental support for PA in children is more important than parents being a role model. More active parents, however, may be more likely to facilitate participation in organised sports. These results underline the importance of the inclusion of parents in health promotion and obesity prevention programmes in children.

Background Research indicates that parents influence their children’s physical activity (PA) and sedentary behaviors (SB) through their parenting styles and practices. Objective The objectives of this paper were to evaluate existing research examining the associations between parenting styles, parenting practices, and PA and SB among Latino children aged between 2 and 12 years, highlight limitations of the existing research, and generate suggestions for future research. Methods The method of this integrative review was informed by methods developed by Whittemore and Knafl, which allow for the inclusion of qualitative, quantitative, and mixed-methods studies. Using the Preferred Reporting Items for Systematic Reviews Meta-Analyses guidelines, five electronic academic databases (PubMed, SPORTDiscus, PsycINFO, PsycARTICLES, and CINAHL) were searched for peer-reviewed, full-text papers published in English. Of the 641 unique citations identified, 67 full-text papers were retrieved, and 16 were selected for review. Results The majority of the 16 reviewed studies were conducted with predominantly Mexican American or Mexican immigrant samples, and only 1 study examined the association between parenting styles and Latino children’s PA and SB. Most (n=15) reviewed studies assessed the influence of parenting practices on children’s PA and SB, and they provide good evidence that parenting practices such as offering verbal encouragement, prompting the child to be physically active, providing logistic support, engaging and being involved in PA, monitoring, and offering reinforcement and rewards encourage, facilitate, or increase children’s PA. The examined studies also provide evidence that parenting practices, such as setting rules and implementing PA restrictions due to safety concerns, weather, and using psychological control discourage, hinder, or decrease children’s PA. Conclusions Because this review found a very small number of studies examining the

Valid instruments of parenting practices related to children's physical activity (PA) are essential to understand how parents affect preschoolers' PA. This study developed and validated a questionnaire of PA-related parenting practices for Chinese-speaking parents of preschoolers in Hong Kong. Parents (n = 394) completed a questionnaire developed using findings from formative qualitative research and literature searches. Test-retest reliability was determined on a subsample (n = 61). Factorial validity was assessed using confirmatory factor analysis. Subscale internal consistency was determined. The scale of parenting practices encouraging PA comprised 2 latent factors: Modeling, structure and participatory engagement in PA (23 items), and Provision of appropriate places for child's PA (4 items). The scale of parenting practices discouraging PA scale encompassed 4 latent factors: Safety concern/overprotection (6 items), Psychological/behavioral control (5 items), Promoting inactivity (4 items), and Promoting screen time (2 items). Test-retest reliabilities were moderate to excellent (0.58 to 0.82), and internal subscale reliabilities were acceptable (0.63 to 0.89). We developed a theory-based questionnaire for assessing PA-related parenting practices among Chinese-speaking parents of Hong Kong preschoolers. While some items were context and culture specific, many were similar to those previously found in other populations, indicating a degree of construct generalizability across cultures.

Full Text Available Background As a conscious activity of an individual, physical activity (PA constitutes an element of the free-time dimension. The type of goal allows us to distinguish between sport and PA: sport performance vs. psychophysical health – hence the idea to develop a tool for measurement of the motivational function of an objective in physical activity and sport. Participants and procedure The normalisation sample consisted of 2141 individuals: 1163 women aged 16-64 (M = 23.90, SD = 8.30 and 978 men aged 16-66 (M = 24.50, SD = 9.40. In the process of validation, a factor analysis, and subsequently validity and reliability analysis of the tool, and normalisation of scales were performed. Results Based on the factor analysis and the degree to which each of the given items conformed to the theory of the motivational function of an objective, the following scales were distinguished: 1 motivational value (the extent to which the objective influences the actions undertaken by an individual, 2 time management (the level of focus on planning, arranging and organizing time for PA, 3 persistence in action (efficiency and persistence of action, and the ability to deal with adversities, and 4 motivational conflict (the level of conflict: PA objectives vs. other objectives. The Cronbach’s α reliability coefficient for this version reached .78. The Inventory of Physical Activity Objectives (IPAO also included questions that allow one to control for variables such as the variety of forms, duration, and frequency of PA, and socio-demographic variables. Conclusions The IPAO, as a new method for measuring motives for physical activity and sport, is characterized by good psychometric properties. The IPAO can serve both scientific research and as a useful tool for personal trainers, helping diagnose the motives for engaging in PA and sports. With knowledge about the purposefulness of actions, it is possible to support and shape additional motivation experienced by

Radioactive wastes may contain both parent and daughter radionuclides. In some cases the transfer parameters of the daughter radio-elements differ significantly from that of the parent ones and therefore the dose contributions in the different pathways might be important to assess separately. The present work has compared 5 different site specific models by a scenario, using contaminated water for drinking and irrigation. Altogether 5 radionuclides from the investigated 10 ones contained radioactive daughter elements. In general, for long term studies in biosphere the steady-state formulations of processes are adequate to assess the contamination, except the infiltration into the deeper soil and sediment layers. According to the results of the modelling and computer simulations, the following daughters are to be assessed separately from their parents with respect to the radiation impact: for parent 231 Pa the daughter 227 Ac, for parent 226 Ra the daughters 222 Rn, 210 Pb and 210 Po and for parent 237 Np the daughter 233 Pa. The dose contributions of the daughters from parents 238 U and 239 Pu are less significant during the considered 100-10000 years. In case of contamination of irrigation water with 1 Bq x m -3 of the parent radionuclide 231 Pa, more than 90% of the external dose from soil exposure comes from the daughter 227 Ac (annually 15 nSv). By a similar contamination with 226 Ra as a parent radionuclide, 60% of the ingestion dose is due to food contamination with the daughters 210 Pb and 210 Po (approximately 150 nSv x a -1 ). (author)

Background Levels of physical activity (PA) in UK children are much lower than recommended and novel approaches to its promotion are needed. The Children, Parents and Pets Exercising Together (CPET) study is the first exploratory randomised controlled trial (RCT) to develop and evaluate an intervention aimed at dog-based PA promotion in families. CPET aimed to assess the feasibility, acceptability and potential efficacy of a theory-driven, family-based, dog walking intervention for 9–11 year olds. Methods Twenty-eight families were allocated randomly to either receive a 10-week dog based PA intervention or to a control group. Families in the intervention group were motivated and supported to increase the frequency, intensity and duration of dog walking using a number of behaviour change techniques. Parents in the intervention group were asked to complete a short study exit questionnaire. In addition, focus groups with parents and children in the intervention group, and with key stakeholders were undertaken. The primary outcome measure was 10 week change in total volume of PA using the mean accelerometer count per minute (cpm). Intervention and control groups were compared using analysis of covariance. Analysis was performed on an intention to treat basis. Results Twenty five families were retained at follow up (89%) and 97% of all outcome data were collected at baseline and follow up. Thirteen of 14 (93%) intervention group parents available at follow up completed the study exit questionnaire and noted that study outcome measures were acceptable. There was a mean difference in child total volume of PA of 27 cpm (95% CI -70, 123) and -3 cpm (95% CI -60, 54) for intervention and control group children, respectively. This was not statistically significant. Approximately 21% of dog walking time for parents and 39% of dog walking time for children was moderate-vigorous PA. Conclusions The acceptability of the CPET intervention and outcome measures was high. Using

To date, there is no physical activity (PA) questionnaire with convergent and construct validity for the oldest-old. The aim of the current study was to investigate the validity of questionnaire-assessed PA in comparison with objective measures determined by uniaxial and triaxial accelerometers and physical performance measures in the oldest-old. Participants were 155 elderly (mean age 90 years) who were examined at the university and agreed to wear an accelerometer for 7 days in the 3-year-follow-up survey of the Tokyo Oldest-Old Survey of Total Health. Fifty-nine participants wore a uniaxial and triaxial accelerometer simultaneously. Self-rated walking, exercise, and household PA were measured using a modified Zutphen PA Questionnaire (PAQ). Several physical performance tests were done, and the associations among PAQ, accelerometer-assessed PA, and physical performances were compared by Spearman's correlation coefficients. Significant, low to moderate correlations between PA measures were seen on questionnaire and accelerometer assessments (ρ = 0.19 to 0.34). Questionnaireassessed PA measure were correlated with a range of lower extremity performance (ρ = 0.21 to 0.29). This PAQ demonstrated convergent and construct validity. Our findings suggest that the PAQ can reasonably be used in this oldest-old population to rank their PA level.

Gender differences in physical activity (PA) trajectories during adolescence are well documented, yet little research has examined whether the determinants of these trajectories vary by child's gender. This study is one of few prospective examinations of gender differences in the influences of psychosocial and socioenvironmental factors on changes in objectively measured PA. Students and parents from elementary and middle schools located in 2 school districts in South Carolina were enrolled in a prospective cohort study of changes in children's PA from elementary to middle school. Measures included children's and/or parents' ratings of various psychosocial and socioenvironmental factors as well as objectively measured PA, children's anthropometric characteristics, and neighborhood factors at fifth and sixth grades. Parents' reports of children's sport and class participation, parent-reported support for PA, and neighborhood resources for PA were protective against declines in PA for both boys and girls. The effects of 2 factors-children's self-efficacy and parents' leisure-time PA-on changes in PA over time were moderated by the child's gender. A better understanding of these dynamics may inform the development of interventions.

Appreciation of the normal position of the hila is essential in screening and diagnosis of the diseases of the chest. Many authors assessed the hilar position in normal adults using PA chest roentgenograms. However there have been no previous publication regarding consolidated assessment of various measurements. The authors carried out the present study to evaluate various hilar measurements including hilar points, hilar distances, difference between both hilar heights, hilar height ratio, and the relationship between the level of the clavicle and hila on the 500 normal PA chest roentgenograms

Positive parenting practices and environmental supports have been linked to physical activity (PA) levels in youth, yet factors associated with positive parenting styles have been understudied in African American adolescents. This study expands on previous literature by examining associations between motivation, parenting factors associated with Self-Determination Theory's psychological needs (competence, autonomy, and relatedness) including authoritative parenting, autonomy support and emotional and tangible support, and adolescent moderate-to-vigorous PA (MVPA) and light PA (LPA). Participants were African American adolescents (N = 148; Mage = 13.6 years; MBMI% = 96.6) and their care-givers (Mage = 43.4 years; MBMI = 37.4) enrolled in the Families Improving Together for Weight Loss trial. Parenting factors were measured using self-report surveys, and PA minutes were measured using 7-day accelerometry estimates. Regression analyses indicated that overall models for MVPA (F(11,134) = 4.35; R2 = 0.26) and LPA (F(11,134) = 5.84, R2 = 0.32) were significant. Adolescent motivation for PA (B = 0.58, SE = 0.16) was positively associated with MVPA minutes. Authoritative parenting (B = 15.71, SE = 4.38) and tangible support (B = 8.53, SE = 4.02) were positively associated with adolescent LPA minutes. Unexpectedly, emotional support was negatively associated with both MVPA (B = -0.47, SE = 0.17) and LPA (B = -11.22, SE = 4.79), with follow-up analyses showing this relationship stronger in males. Findings highlight the importance of adolescent motivation for PA onMVPA and positive parenting styles and tangible supports on adolescent LPA in overweight African American youth. Recommendations for integrating these factors within the context of intervention studies are discussed.

2010-01-01

Full Text Available Abstract Background With rates of childhood obesity increasing, physical activity (PA promotion especially in young children has assumed greater importance. Given the limited effectiveness of most interventions to date, new approaches are needed. The General Systems theory suggests that involving parents as intervention targets may be effective in fostering healthier life styles in children. We describe the development of a parent-focused participatory intervention and the procedures used to evaluate its effectiveness in increasing daily PA in preschoolers. Methods/Design Thirty-seven South German preschools were identified for this study and agreed to participate. Using a two-armed, controlled cluster-randomized trial design we test a participatory intervention with parents as the primary target group and potential agents of behavioural change. Specifically, the intervention is designed to engage parents in the development, refinement and selection of project ideas to promote PA and in incorporating these ideas into daily routines within the preschool community, consisting of children, teachers and parents. Our study is embedded within an existing state-sponsored programme providing structured gym lessons to preschool children. Thus, child-based PA outcomes from the study arm with the parent-focused intervention and the state-sponsored programme are compared with those from the study arm with the state-sponsored programme alone. The evaluation entails baseline measurements of study outcomes as well as follow-up measurements at 6 and 12 months. Accelerometry measures PA intensity over a period of six days, with the mean over six days used as the primary outcome measure. Secondary outcomes include childrens' BMI, a sum of averaged skin fold thickness measurements across multiple sites, and PA behaviour. Longitudinal multilevel models are used to assess within-subject change and between-group differences in study outcomes, adjusted for covariates

Full Text Available Abstract Background Many children do not engage in sufficient levels of physical activity (PA and spend too much time screen-viewing (SV. High levels of SV (e.g. watching TV, playing video games and surfing the internet and low levels of PA have been associated with adverse health outcomes. Parenting courses may hold promise as an intervention medium to change children’s PA and SV. The current study was formative work conducted to design a new parenting programme to increase children’s PA and reduce their SV. Specifically, we focussed on interest in a course, desired content and delivery style, barriers and facilitators to participation and opinions on control group provision. Methods In-depth telephone interviews were conducted with thirty two parents (29 female of 6–8 year olds. Data were analysed thematically. An anonymous online survey was also completed by 750 parents of 6–8 year old children and descriptive statistics calculated. Results Interview participants were interested in a parenting course because they wanted general parenting advice and ideas to help their children be physically active. Parents indicated that they would benefit from knowing how to quantify their child’s PA and SV levels. Parents wanted practical ideas of alternatives to SV. Most parents would be unable to attend unless childcare was provided. Schools were perceived to be a trusted source of information about parenting courses and the optimal recruitment location.

Full Text Available Abstract Background Sufficient daily physical activity (PA is necessary for physical, social and mental health benefits during growth. Most of the available data on children is based on subjective reports, while only limited data on objective PA and sedentary levels is available for primary school children. Increased PA is also an important health indicator of body composition parameters, especially body adiposity indices. The aim of the present study was to determine objectively the amount of daily PA levels at different intensities and sedentary time in normal-weight (NW and overweight (OW 7–9-year-old boys and girls, and to find associations between objectively measured PA levels and sedentary time with different body composition values. Methods Two hundred and seventy eight (142 boys and 136 girls primary school children aged 7.9 ± 0.7 years participated in this study. Objective PA intensity and sedentary levels were measured over 7 days by accelerometry. Indices of total fat mass (body fat %, sum of skinfolds, fat distribution (waist-to-height ratio and muscular component (fat free mass [FFM] were calculated from measured anthropometric parameters. Results There were no differences (p > 0.05 in PA intensity levels and sedentary time between boys and girls as well as between NW and OW children. About 11 % of children met the current guidelines of at least 60 min per day of moderate-to-vigorous PA (MVPA. Sedentary time was positively and negatively associated (p < 0.05 with all body fat and FFM values, respectively. Moderate and vigorous PA along with MVPA were negatively and positively associated (p < 0.05 with all body fat and FFM indices, respectively. Conclusions The results of present study showed that about 11 % of primary school children were engaged in PA of at least 60 min of MVPA daily. While MVPA is negatively associated with fat mass indices and positively associated with FFM regardless of different

The agreement between parent-reported and directly measured child language and parenting behaviors

Full Text Available Parenting behaviors are commonly targeted in early interventions to improve children’s language development. Accurate measurement of both parenting behaviors and children’s language outcomes is thus crucial for sensitive assessment of intervention outcomes. To date, only a small number of studies have compared parent-reported and directly measured behaviors, and these have been hampered by small sample sizes and inaccurate statistical techniques, such as correlations. The Bland-Altman Method and Reduced Major Axis regression represent more reliable alternatives because they allow us to quantify fixed and proportional bias between measures. In this study, we draw on data from two Australian early childhood cohorts (N= 201 parents and slow-to-talk toddlers aged 24 months; and N=218 parents and children aged 6-36 months experiencing social adversity to (1 examine agreement and quantify bias between parent-reported and direct measures, and (2 to determine socio-demographic predictors of the differences between parent-reported and direct measures. Measures of child language and parenting behaviors were collected from parents and their children. Our findings support the utility of the Bland-Altman Method and Reduced Major Axis regression in comparing measurement methods. Results indicated stronger agreement between parent-reported and directly measured child language, and poorer agreement between measures of parenting behaviors. Child age was associated with difference scores for child language; however the direction varied for each cohort. Parents who rated their child’s temperament as more difficult tended to report lower language scores on the parent questionnaire, compared to the directly measured scores. Older parents tended to report lower parenting responsiveness on the parent questionnaire, compared to directly measured scores. Finally, speaking a language other than English was associated with less responsive parenting behaviors on the

AIMS: To study the association between self-reported physical activity (PA) and objectively measured PA, resting heart rate, and physical fitness. METHODS: During 2007-08, 5017 men and 5607 women aged 30-69 years attended the sixth survey of the Tromsø study. Self-reported PA during leisure......-time and work were assessed and resting heart rate was measured. In a sub-study, the activity study, PA (Actigraph LLC) and physical fitness (VO₂(max)) were objectively measured among 313 healthy men and women aged 40-44 years. RESULTS: Self-reported leisure PA was significantly correlated with VO₂(max) (ml...... women than men met the international recommendations of 10,000 step counts/day (27% vs. 22%) and the recommendation of at least 30 minutes/day of moderate-to-vigorous intensities (30% vs. 22 %).

Childhood physical activity (PA) has declined in the western world recently. To combat child inactivity, government programs have been organized to promote PA within families. It is important for physiotherapists to understand the influence parents perceive to have on their child's PA habits in order to better encourage a positive parental influence. The purpose of this study is to explore how parents perceive their influence on their child/children's PA through an interpretative phenomenological analysis (IPA) approach. This qualitative study used a phenomenological approach with semi-structured interviews conducted with five participants. The interviews were analyzed using elements of IPA. Master themes developed with their corresponding subthemes: creating an environment of opportunity--logistics, opportunities through encouragement and PA within the family, barriers to PA--barriers created by parents and barriers created by external factors, and parent and child interactions--children communicating interest and disinterest in PA and parent's attitudes toward children's disinterest. The findings suggest that parents perceive themselves to have a greater positive influence on their children rather than negative. The barriers that parents create are not perceived to prevent their child's PA but rather restrict it. Many participants reported enjoying doing PA with their children and used PA as an opportunity for family time, indicating a dual purpose for PA. © The Author(s) 2014.

Physical aggression (PA) in the toddler years is common and developmentally normal, however, longitudinal research shows that frequent PA is highly stable and associated with long-term negative outcomes. Significant research has demonstrated the efficacy of parenting interventions for reducing externalizing behavior in children yet their typical length may overburden families, leading to low participation rates and high attrition rates. To increase the reach of parenting interventions and impact on the prevalence of externalizing behavior problems, brief interventions are needed. This RCT compared a standard (8 session) group Triple P to a brief (3 session) discussion group and a waitlist control for reducing toddler PA, dysfunctional parenting and related aspects of parent functioning. Sixty-nine self-referred families of toddlers with PA were randomized to the respective conditions. At post-assessment, families in the standard intervention had significantly lower levels of observed child aversive behavior, mother reports of PA and dysfunctional parenting, and higher levels of mother- and partner-rated behavioral self-efficacy than the waitlist control. Families in the standard intervention also had significantly lower levels mother-rated dysfunctional parenting than the brief intervention, and the brief intervention had significantly lower levels of mother-rated dysfunctional parenting than waitlist. There were no significant group differences at post-assessment for measures of parental negative affect or satisfaction with the partner relationship. By 6 month follow-up, families in the brief and standard intervention did not differ significantly on any measure. The implications of the findings to delivery of brief parenting interventions are discussed. Aggr. Behav. 43:291-303, 2017. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

The aim of this research was to test a multimedia permission/assent (P/A) process. The overall hypothesis was that children and their parents exposed to a multimedia P/A process would have better comprehension compared with those exposed to a text-based process. Traditional and multimedia P/A processes were created by using an innovative learning-objective approach. A total of 194 parent-child dyads (children aged 11-14 years) were enrolled: 24 dyads in a prestudy testing P/A components for preference and effect on comprehension and 170 dyads in a randomized trial of a multimedia or paper P/A process for a hypothetical study. Participants were predominantly white and were from a metropolitan area served by a tertiary care pediatric hospital and outpatient facility. Comprehension of 8 essential elements of the P/A process was assessed. The majority of prestudy subjects preferred the video version of the dual-energy radiograph absorptiometry description over the animated and paper versions combined (41 of 48 [85%]; P better overall comprehension compared with the paper P/A process (P = .0009), and there were highly significant differences in understanding of study procedures (P = .0002) and risks (P multimedia group had significantly better overall comprehension (P = .03). Multimedia approaches to the research P/A process may improve overall understanding of research participation for children and parents. Improved understanding of study-specific research components (rather than research rights) may improve overall comprehension.

The study aimed to examine caregiving burden and levels of distress, accommodating behaviours, expressed emotion (EE) and carers' skills, in parents of adolescents with anorexia nervosa. A semi-structured interview assessed the objective burden (time spent across caregiving tasks) in parents (n = 196) of adolescents (n = 144) receiving outpatient treatment for anorexia nervosa. Subjective burden (carers' distress), accommodating behaviours, EE and carers' skills were measured by self-report. Mothers, on average, spent 2.5 h/day of care, mainly providing food and emotional support, compared with 1 h/day by fathers. The level of distress and accommodating behaviour was significantly lower in fathers than in mothers. Accommodating behaviours mediated the relationship between objective burden and subjective burden in mothers, whereas EE and carers' skills did not mediate this relationship for either parent. The objective burden for most mothers is high. In order to reduce subjective burden, it may be helpful to target accommodating behaviours. ISRCTN83003225 - Expert Carers Helping Others (ECHO).

Full Text Available Parents influence on their young children's physical activity (PA behaviours was examined in a sample of 102 preschool-aged children (54 boys. Questionnaires regarding family sociodemographics and physical activity habits were completed. Results showed that children who received greater parental support for activity (B=.78, P<.10 and had parents who rated PA as highly enjoyable (B=.69, P<.05 were significantly more likely to engage in one hour or more of daily PA. Being an older child (B=−.08, P<.01, having older parents (B=−.26, P<.01, and watching more than one hour of television/videos per day (B=1.55, P<.01 reduced the likelihood that a child would be rated as highly active. Children who received greater parental support for PA were 6.3 times more likely to be highly active than inactive (B=1.44, P<.05. Thus, parents can promote PA among their preschoolers, not only by limiting TV time but also by being highly supportive of their children's active pursuits.

High volume of sedentary behavior (SB on the other hand is harmful for health. The purpose of the study was to describe objectively measured PA and SB in Finnish school children. Furthermore, the study aimed at analyzing the association between PA, SB and perceived health status. Methods The participants of this cross-sectional study were 7- to 14-year-old girls and boys (n = 1029, whose PA and SB during waking hours were measured with Hookie AM 20-accelerometer (Traxmeet Ltd, Espoo, Finland for seven days. Perceived health status was assessed by a questionnaire. Association between PA, SB and health status was analyzed by logistic regression analysis using SPSS (Inc, Chicago IL. Results Participants (age 10.3 ± 1.9, 52 % girls with sufficient accelerometer data (at least 4 days with ≥ 10 h/day were included into the study (n = 851, 88 %. The average measurement time was 13 h 27 min per day. Participants spent on average 54 % (7 h 18 min of waking hours sedentary, mainly sitting. They stood still on average 9 % of the time (1 h 15 min. Light PA covered on average 18 % (2 h 24 min and moderate-to-vigorous PA 19 % (2 h 30 min. Younger participants and boys were more active than the older ones and girls. Most (63 % of the participants perceived their health status as excellent. In an adjusted logistic regression analysis greater sedentary time decreased the odds for excellent perceived health status (p = 0.001. In contrast higher number of steps per day (p = 0.019 increased the odds. Conclusions Participants spent over half of their waking hours sedentary. Less SB and more steps were associated with excellent perceived health. There is a need for dose-response analyses between objectively measured PA and SB and specific health outcomes in children and adolescents. Also patterns of objectively measured

SYNOPSIS Objective Parents’ poor monitoring of adolescents’ whereabouts and activities is commonly linked to adolescents’ increased engagement in delinquent behaviors. Yet, different domains of parental monitoring (parental monitoring behaviors vs. parental knowledge) and reports from multiple informants (parent vs. adolescent) may vary in their links to delinquent behavior. Design Seventy-four parental caregivers and 74 adolescents completed survey measures of parental monitoring and knowledge, and adolescents completed self-report surveys of delinquent behavior. Results We observed low-to-moderate magnitudes of correspondence between parent- and adolescent-reports of parental monitoring behaviors and parental knowledge. Adolescent self-reported delinquent behavior related to parent and adolescent reports of parental monitoring behaviors and parental knowledge, with adolescents who self-reported engagement in delinquent behaviors evidencing lower levels of parental knowledge and higher levels of poor monitoring compared to adolescents who did not self-report engagement in delinquent behaviors. Adolescent self-reported engagement in delinquent behaviors evidenced stronger links to parental monitoring when based on adolescent reports of monitoring (relative to parent reports), whereas stronger links held between adolescent self-reported delinquent behavior and parental knowledge when based on parent reports of knowledge (relative to adolescent reports). Conclusions Links between monitoring and adolescents’ delinquent behavior vary by the kind of monitoring measure completed as well as the informant completing the measure. These findings inform measurement selection in research and clinical assessments of parental monitoring and adolescent delinquent behavior. PMID:27482171

In children, being sufficiently physically active, having low levels of screen-time and having a healthy diet are largely influenced by parenting practices. Children of parents applying positive parenting practices are at lower risk for overweight and obesity. Therefore, we investigated the effect of a health promoting online video intervention for parents ('Movie Models') on children's physical activity (PA), screen-time and healthy diet, and on specific parenting practices and parental self-efficacy related to these parenting practices. The online videos are delivered to parents of primary schoolchildren, and were based on real-life scenarios. A two-armed, quasi experimental design was used. Parents of primary schoolchildren were recruited between November and December 2013 by spreading an appeal in social media, and by contacting primary schools. Participating parents were predominantly of high socio-economic status (SES) (83.1%), and only 6.8% of children were overweight/obese. Intervention group participants were invited to watch online videos for 4 weeks. Specific parenting practices, parental self-efficacy, PA, screen-time and healthy diet of the child were assessed at baseline (T0), at one (T1) and at four (T2) months post baseline. Repeated Measures (Multivariate) ANOVAs were used to examine intervention effects. The potential moderating effect of age and gender of the child and parental SES was also examined. Between T0 and T2, no significant intervention effects were found on children's PA, screen-time or healthy diet. Most significant intervention effects were found for more complex parenting practices (e.g., an increase in motivating the child to eat fruit). Subgroup analyses showed that the intervention had more effect on the actual parenting practices related to PA, screen-time and healthy diet in parents of older children (10-12 years old), whereas intervention effects on parental self-efficacy related to those behaviors were stronger in parents of

Research indicates that parents influence their children's physical activity (PA) and sedentary behaviors (SB) through their parenting styles and practices. The objectives of this paper were to evaluate existing research examining the associations between parenting styles, parenting practices, and PA and SB among Latino children aged between 2 and 12 years, highlight limitations of the existing research, and generate suggestions for future research. The method of this integrative review was informed by methods developed by Whittemore and Knafl, which allow for the inclusion of qualitative, quantitative, and mixed-methods studies. Using the Preferred Reporting Items for Systematic Reviews Meta-Analyses guidelines, five electronic academic databases (PubMed, SPORTDiscus, PsycINFO, PsycARTICLES, and CINAHL) were searched for peer-reviewed, full-text papers published in English. Of the 641 unique citations identified, 67 full-text papers were retrieved, and 16 were selected for review. The majority of the 16 reviewed studies were conducted with predominantly Mexican American or Mexican immigrant samples, and only 1 study examined the association between parenting styles and Latino children's PA and SB. Most (n=15) reviewed studies assessed the influence of parenting practices on children's PA and SB, and they provide good evidence that parenting practices such as offering verbal encouragement, prompting the child to be physically active, providing logistic support, engaging and being involved in PA, monitoring, and offering reinforcement and rewards encourage, facilitate, or increase children's PA. The examined studies also provide evidence that parenting practices, such as setting rules and implementing PA restrictions due to safety concerns, weather, and using psychological control discourage, hinder, or decrease children's PA. Because this review found a very small number of studies examining the relationship between parenting styles and Latino children's PA and SB

Full Text Available Background: The increasing prevalence of childhood obesity is a global concern. Although childhood obesity has grown as a result of a complex array of interactions among multiple behavioural, biological, and environmental factors, excessive screen time (ST and low levels of physical activity (PA are often discussed as causal factors. Therefore, it is beneficial to identify risky family behavioural patterns contributing to the increasing prevalence of obesity even in pre-schoolers. Objective: The main aim of the study was to assess whether parental obesity and parent-child behavioural patterns (PA and ST affect the odds of overweight/obesity in 4-to-7-year-old preschool children. Methods: We analysed seven-day PA and ST behaviour among families with pre-schoolers that included 194 preschool children (88 girls and 106 boys and their parents (165 mothers and 111 fathers. PA was monitored by means of unsealed Yamax pedometers for at least eight hours a day over seven consecutive days during spring (April/May and autumn (September/October of 2015. ST was recorded by parents on family log book sheets. To assess the odds of parents' obesity and PA/ST variables in relation to child overweight/obesity, a logistic regression (backward method was used. Results: Most children (n = 157 reported normal weight (87 boys, 70 girls, 37 children were overweight or obese (19 boys, 18 girls. Children's excessive ST (> 1 hour/day (OR: 5.65/33.19 on weekdays/weekends, mothers' obesity (OR: 13.80/28.84 on weekdays/weekends, mothers' excessive ST (> 2 hours/ day (OR: 32.46 at weekends, and children's male gender (OR: 38.69 at weekends were significantly (p < .05 associated with higher odds of overweight/obesity in the preschool children. Conclusions: Uncovering parent-child behavioural patterns provides insight into the lifestyle of families with pre-schoolers and is a source of valuable information for designing and implementing family-based intervention

A growing body of research has examined the relationship between perceived neighborhood safety and parental encouragement for child physical activity (PA), yet these potential predictors have not been studied together to predict child outdoor PA. The purpose of this study is to examine these predictors and parent- and child-reported child outdoor PA. The Texas Childhood Obesity Research Demonstration study collected data from fifth-grade students attending 31 elementary schools across Austin and Houston and their parents (N = 748 parent-child dyads). Mixed-effects linear and logistic regressions stratified by gender and adjusted for sociodemographic covariates assessed associations among parental-perceived neighborhood safety, parental encouragement for child's outdoor PA, and parent- and child-reported child's outdoor PA. Parental-perceived neighborhood safety was significantly associated with encouraging outdoor PA (P = .01) and child-reported child's outdoor PA in boys, but not in girls. Significant associations were found between parental encouragement and child-reported outdoor PA for girls (P < .05) and parent-reported outdoor PA (P < .01) for boys and girls. Parent encouragement of PA and neighborhood safety are potential predictors of child outdoor PA and could be targeted in youth PA interventions.

Full Text Available Few studies examine how objectively measured use of local physical activity resources contributes to objectively-measured healthy physical activity and weight changes over time. We utilized objective measures to test whether changes in active travel and uses of three physical activity (PA resources–parks, recreation centers, and transit– related to changes in PA and BMI. Adults (n=536 in Salt Lake City, UT, wore accelerometer and GPS units in 2012 and 2013, before and after neighborhood rail completion. Regression outcomes included accelerometer counts per minute (cpm, MVPA (moderate-to-vigorous activity minutes/10h accelerometer wear and measured BMI; key predictors were changes in active travel and PA resource uses (former and new uses. Significant results (all p<0.05 showed that increased active travel related to increased total PA (59.86cpm and 8.50 MVPA; decreased active travel related to decreased MVPA (−3.01 MVPA. Poorer outcomes were seen after discontinuing use of parks (−36.29cpm, −5.73 MVPA, and +0.44 BMI points, recreation centers (−6.18 MVPA, and transit (−48.14cpm, −5.43 MVPA, and +0.66 BMI. Healthier outcomes were seen after commencing use of parks (29.83cpm, 5.25 MVPA, recreation centers (44.63cpm and transit (38.44cpm, 4.17 MVPA, and −0.56 BMI. Transit and park/recreational center uses were unrelated, although park users were more likely to be recreation center users. Active travel and use of three neighborhood PA resources relate to healthy activity and could be fostered by policy and design.

In recent years healthcare professionals have faced increasing concerns about the value of childhood vaccination and many find it difficult to deal with parents who object to vaccination. In general, healthcare professionals are advised to listen respectfully to the objections of parents, provide honest information, and attempt to correct any misperceptions regarding vaccination. Religious objections are one of the possible reasons for refusing vaccination. Although religious objections have a long history, little is known about the way healthcare professionals deal with these specific objections. The aim of this study is to gain insight into the responding of healthcare professionals to parents with religious objections to the vaccination of their children. A qualitative interview study was conducted with health care professionals (HCPs) in the Netherlands who had ample experience with religious objections to vaccination. Purposeful sampling was applied in order to include HCPs with different professional and religious backgrounds. Data saturation was reached after 22 interviews, with 7 child health clinic doctors, 5 child health clinic nurses and 10 general practitioners. The interviews were thematically analyzed. Two analysts coded, reviewed, discussed, and refined the coding of the transcripts until consensus was reached. Emerging concepts were assessed using the constant comparative method from grounded theory. Three manners of responding to religious objections to vaccination were identified: providing medical information, discussion of the decision-making process, and adoption of an authoritarian stance. All of the HCPs provided the parents with medical information. In addition, some HCPs discussed the decision-making process. They verified how the decision was made and if possible consequences were realized. Sometimes they also discussed religious considerations.

Childhood obesity is a growing problem. As more researchers become involved in the study of parenting influences on childhood obesity, there appears to be a lack of agreement regarding the most important parenting constructs of interest, definitions of those constructs, and measurement of those constructs in a consistent manner across studies. This article aims to summarize findings from a working group that convened specifically to discuss measurement issues related to parental influences on childhood obesity. Six subgroups were formed to address key measurement issues. The conceptualization subgroup proposed to define and distinguish constructs of general parenting styles, feeding styles, and food parenting practices with the goal of understanding interrelating levels of parental influence on child eating behaviors. The observational subgroup identified the need to map constructs for use in coding direct observations and create observational measures that can capture the bidirectional effects of parent-child interactions. The self-regulation subgroup proposed an operational definition of child self-regulation of energy intake and suggested future measures of self-regulation across different stages of development. The translational/community involvement subgroup proposed the involvement of community in the development of surveys so that measures adequately reflect cultural understanding and practices of the community. The qualitative methods subgroup proposed qualitative methods as a way to better understand the breadth of food parenting practices and motivations for the use of such practices. The longitudinal subgroup stressed the importance of food parenting measures sensitive to change for use in longitudinal studies. In the creation of new measures, it is important to consider cultural sensitivity and context-specific food parenting domains. Moderating variables such as child temperament and child food preferences should be considered in models.

The data regarding prospective associations between physical activity (PA) and adiposity in youth are inconsistent. The objective of this study was to investigate associations between baseline levels of objectively measured PA and changes in adiposity over 2.5 years from mid-to-late adolescence. This was an observational cohort study in 728 school students (43% boys) from Cambridgeshire, United Kingdom. Fat mass index (FMI, kg m(-2) ) was estimated at baseline (mean ± standard deviation age: 15 ± 0.3 years) and follow-up (17.5 ± 0.3 years) by anthropometry and bioelectrical impedance. Habitual PA was assessed at baseline by ≥3 d combined heart rate and movement sensing. Average daily PA energy expenditure (PAEE) and the time (min d(-1) ) spent in light, moderate and vigorous intensity PA (LPA, MPA and VPA, respectively) was estimated. Multilevel models were used to investigate associations between baseline PA and change in FMI (ΔFMI). Adjustment for baseline age, sex, follow-up duration, area-level socioeconomic status, season of PA assessment, sedentary time, energy intake and sleep duration was made; baseline FMI was also added in a second model. FMI increased significantly over follow-up (0.6 ± 1.2 kg m(-2) , P positively predicted ΔFMI in overfat participants (P ≤ 0.030), as did VPA in initially normal fat participants (P ≤ 0.044). There were further positive associations between PAEE and ΔFMI in normal fat participants, and between MPA and ΔFMI in both fat groups, when adjusted for baseline FMI (P ≤ 0.024). Baseline PAEE and its subcomponents were positively associated with small and unlikely clinically relevant increases in ΔFMI. These counter-intuitive findings may be explained by behavioural changes during the course of study follow-up. © 2015 The Authors.

Substantial evidence suggests that weight gain in early life is associated with increased adiposity and other metabolic disorders later in life. It is, however, unknown whether physical activity (PA) may modify these associations. We aimed to examine whether objectively measured PA at 30 years modified the associations between conditional weight gain in infancy (0-2 y) and childhood (2-4 y) with fat mass index (FMI) and visceral abdominal fat measured at age 30 years. Prospective birth cohort study in Pelotas, Brazil, including 1874 participants with weight data at birth, two and four years of age, and measures of FMI, visceral abdominal fat and PA at a mean age of 30.2 years. At age 30, time spent (min/day) in moderate-to-vigorous physical activity (MVPA) was measured objectively using a wrist-worn accelerometer worn for four to seven consecutive days.. Multiple linear regression analyses was performed to assess the associations between conditional weight gain and outcome variables at 30 years, adjusting for covariates. We examined whether PA modified the association between conditional weight gain and the outcomes of interest by introducing an interaction term (conditional weight gain × PA) in the models. Conditional weight gain in infancy and childhood were both positively associated with later FMI (infancy weight gain: β = 0.68, 95% CI: 0.48, 0.88; P gain: β = 0.91, 95% CI: 0.70, 1.11; P gain and later FMI (β = -0.006, 95% CI: -0.011, -0.001; P = 0.029), suggesting stronger associations between weight gain and FMI in those with lower levels of MVPA. Conditional weight gain in childhood was also positively associated with visceral abdominal fat (β = 0.24, 95% CI: 0.15, 0424, P gain between 2 and 4 years of age is associated with increased FMI at age 30 years. However, higher levels of MVPA appear to attenuate this detrimental association.

The increasing prevalence of childhood overweight/obesity caused by an unhealthy diet, insufficient physical activity (PA) and high levels of sedentary behaviour (SB) is a prominent public health concern. Parenting practices may contribute to healthy behaviour change in children, but well-researched examples are limited. The aim of this study is to describe the systematic development of an intervention for parents to prevent childhood overweight/obesity through the improvement of parenting practices. The six steps of the Intervention Mapping Protocol (IMP), a theory- and evidence-based tool to develop health-related interventions, were used as a framework to develop the 'Movie Models' programme. In Step 1, a needs assessment was performed to better understand the health problem of overweight/obesity in children and its association with diet, PA and SB. In Step 2, the programme goal (increasing the adoption of effective parenting practices) was sub-divided into performance objectives. Change objectives, which specify explicit actions required to accomplish the performance objectives, were also identified. Step 3 included the selection of theoretical methods (e.g. 'modelling' and 'images'), which were then translated into the practical strategy of online parenting videos. Step 4 comprised the development of a final intervention framework, and Step 5 included the planning of programme adoption and implementation. The final phase, Step 6, included the development of an effect- and process-evaluation plan. The IMP was used to structure the development of 'Movie Models', an intervention targeting specific parenting practices related to children's healthy diet, PA, SB, and parental self-efficacy. A clear framework for process analyses is offered, which aims to increase the potential effectiveness of an intervention and can be useful for those developing health promotion programmes. © The Author(s) 2016.

We examined (1) the relationship that parental objective social status (OSS) and subjective social status (SSS) have with children's health-related quality of life (HRQOL), (2) whether SSS mediates the association between OSS and HRQOL, and (3) whether these associations differ among Black, Latino, and White children. Data came from 4,824 Black, Latino, and White 5th graders in the Healthy PassagesTM study. OSS was measured as parent educational attainment and net equivalent household income. SSS was measured by parent rating of community and national standing on the MacArthur Scale of Subjective Social Status. Child HRQOL was measured with child report on the Pediatric Quality of Life Inventory (PedsQL) physical and psychosocial scales. Structural equation modeling path analysis was conducted using Mplus version 7.4. The data supported the hypothesized measurement and structural models. Whereas parental OSS was positively related to psychosocial HRQOL for all three racial/ethnic groups and to physical HRQOL for Latino children, parental SSS was not related to either for any of the racial/ethnic groups. Therefore, mediation by SSS was not supported for any group. OSS was confirmed to have stronger association with children's HRQOL than parental SSS. This is in contrast to some research on adults, raising the questions of how best to assess SSS relevant to children and at what point in development SSS may influence children's health and well-being. The persistent relationship found between parental OSS and child health suggests that efforts to improve low socioeconomic resources in families may contribute to improve children's health.

Physical functioning can be assessed by different approaches that are characterized by increasing levels of individual appraisal. There is insufficient insight into which approach is the most informative in patients with ankylosing spondylitis (AS) compared with control subjects. The objective of this study was to compare patients with AS and control subjects regarding 3 approaches of functioning: experienced ability to perform activities (Bath Ankylosing Spondylitis Functional Index [BASFI]), self-reported amount of physical activity (PA) (Baecke questionnaire), and the objectively measured amount of PA (triaxial accelerometer). This case-control study included 24 AS patients and 24 control subjects (matched for age, gender, and body mass index). Subjects completed the BASFI and Baecke questionnaire and wore a triaxial accelerometer. Subjects also completed other self-reported measures on disease activity (Bath AS Disease Activity Index), fatigue (Multidimensional Fatigue Inventory), and overall health (EuroQol visual analog scale). Both groups included 14 men (58%), and the mean age was 48 years. Patients scored significantly worse on the BASFI (3.9 vs 0.2) than their healthy peers, whereas PA assessed by Baecke and the accelerometer did not differ between groups. Correlations between approaches of physical functioning were low to moderate. Bath Ankylosing Spondylitis Functional Index was associated with disease activity (r = 0.49) and physical fatigue (0.73) and Baecke with physical and activity related fatigue (r = 0.54 and r = 0.54), but total PA assessed by accelerometer was not associated with any of these experience-based health outcomes. Different approaches of the concept physical functioning in patients with AS provide different information. Compared with matched control subjects, patients with AS report more difficulties but report and objectively perform the same amount of PA.

Physical activity (PA) is associated with health benefits, already in childhood. However, little is known about actual levels, patterns and gender differences in PA level in very young children. This study examines Chinese one-year-old children and their parents' PA levels and patterns, and assesses the correlations between children's PA level and gender, body mass index standard deviation score (BMI SDS), parental BMI and parental PA level. Data from 123 families participating in the Early STOPP China study were used. Families were recruited based on parental BMI and were classified as either high-risk or low-risk of obesity. Parents and children wore an ActiGraph GT3X+ to assess the average PA levels. PA levels and hourly patterns during weekdays and weekends were examined as were correlations with gender, BMI SDS, parental BMI and parental PA levels. There were no significant differences in children's averaged PA between risk groups, genders, or between weekdays and weekends. Children's peak average activity level was at 7 pm and they were least active at 3 pm (pgender, BMI SDS, parental BMI or paternal PA levels. Maternal PA was found positively associated with child PA (pgender, BMI SDS, parental BMI or paternal PA. Larger scale studies with more contextual information are needed to improve the understanding of our findings.

Parents’ views on child physical activity and their implications for physical activity parenting interventions: a qualitative study

Bentley Georgina F

2012-11-01

Full Text Available Abstract Background Establishing healthy physical activity (PA behaviours in early childhood is important for future PA behaviours. Parents play a central role in young children’s PA. However, there is currently little research on parenting interventions to increase child PA. This study was formative work to inform the content of a pilot randomised-controlled trial. Methods In-depth telephone interviews were carried out with 32 parents of 6 to 8 year old children residing in two areas that varied in their socio-economic characteristics, in Bristol, UK. Data were analysed thematically using a framework approach. Results Most parents described their child as being active or very active and indicated that they did not perceive a need for an increase in their child’s PA. Parents used a variety of visual cues to make this judgement, the most common being that they perceived their child as having lots of energy or that they did not view them as overweight. Parents reported environmental factors such as monetary cost, time constraints, lack of activity provision and poor weather as the main barriers to their child’s PA. Parental support and child’s enjoyment of PA appeared to be important facilitators to children participating in PA. Conclusion Improving parents’ knowledge of the PA recommendations for children, and increasing their awareness of the benefits of PA beyond weight status may be an important first step for a parenting PA intervention. Although parents commonly perceive environmental factors as the main barriers to their child’s PA, parental concern about low levels of child PA, their capacity to support behaviour change, child motivation, self confidence and independence may be key areas to address within an intervention to increase child PA. Effective methods of helping parents address the latter have been developed in the context of generic parenting programmes.

Parenting Style and Generativity Measured in College Students and Their Parents

Directory of Open Access Journals (Sweden)

Denise D. Guastello

2014-01-01

Full Text Available The logical consistency between generativity and the authoritative parenting style led to the hypothesis that the two behavior patterns or orientations were related. Survey measurements of perceived parenting style (authoritarian, authoritative, and permissive and generativity in 559 university students and their respective parents were compared. The authoritative parenting style correlated positively with generativity for both students and parents. Both students and mothers scored significantly higher on generativity than fathers, but no significant difference was found between students’ and mothers’ generativity. Hierarchical regression showed that students’ generativity was proximally related to their perceptions of their mothers’ authoritative parenting style, their mothers’ reports of parenting style, and their mothers’ generativity. Father’s generativity or parenting style did not make any additional contributions. The pattern of results suggested that generativity is a learned orientation and more often from mothers than from fathers. The role of maturation might not be as strong as developmental theory would suggest. Several avenues of future research were outlined.

We point out that current calculations of inclusive two-particle correlations in p-A collisions based on the Color Glass Condensate approach exhibit a contribution from Hanbury–Brown–Twiss correlations. These HBT correlations are quite distinct from the standard ones, in that they are apparent for particles widely separated in rapidity. The transverse size of the emitter which is reflected in these correlations is the gluonic size of the proton. This raises an interesting possibility of measuring the proton size directly by the HBT effect of particle pairs produced in p-A collisions.

Full Text Available Purpose. Our physiopathological assumption is that u-PA, t-PA, and PAI-1 are released by calcified aortic valves and play a role in the calcification of these valves. Methods. Sixty-five calcified aortic valves were collected from patients suffering from aortic stenosis. Each valve was incubated for 24 hours in culture medium. The supernatants were used to measure u-PA, t-PA, and PAI-1 concentrations; the valve calcification was evaluated using biphotonic absorptiometry. Results. Aortic stenosis valves expressed normal plasminogen activators concentrations and overexpressed PAI-1 (u-PA, t-PA, and PAI-1 mean concentrations were, resp., 1.69 ng/mL ± 0.80, 2.76 ng/mL ± 1.33, and 53.27 ng/mL ± 36.39. There was no correlation between u-PA and PAI-1 (r=0.3 but t-PA and PAI-1 were strongly correlated with each other (r=0.6. Overexpression of PAI-1 was proportional to the calcium content of the AS valves. Conclusions. Our results demonstrate a consistent increase of PAI-1 proportional to the calcification. The overexpression of PAI-1 may be useful as a predictive indicator in patients with aortic stenosis.

Uncertainty persists regarding adequate measurement of parenting behavior during early adolescence. The present study aimed to clarify the conceptual structure of parenting by evaluating three different models that include support, psychological control, and various types of behavioral control (i.e., proactive, punitive, and harsh punitive control). Furthermore, we examined measurement invariance of parenting ratings by 1,111 Flemish adolescents from Grade 7 till 9, their mother, and father. Finally, criterion validity of parenting ratings was estimated in relation to adolescent problem behavior. Results supported a five-factor parenting model indicating multiple aspects of behavioral control, with punitive and harsh punitive control as more intrusive forms and proactive control as a more supportive form. Similar constructs were measured for adolescents, mothers, and fathers (i.e., configural and metric invariance), however on a different scale (i.e., scalar noninvariance). Future research and clinical practices should acknowledge these findings in order to fully grasp the parenting process. © The Author(s) 2014.

So far, the conceptualization and measurement of parental burnout have been deduced from those of job burnout. As a result, it is unclear whether current measures of parental burnout constitute the best representation of the parental burnout construct/syndrome: the possibility cannot be excluded that some dimensions ought to be added, which would change the structure and definition of parental burnout. In this study, the conceptualization and measurement of parental burnout were approached using an inductive method, in which the parental burnout phenomenon was (re)constructed based solely on the testimonies of burned-out parents. Items extracted from their testimonies were presented to a sample of French-speaking and English-speaking parents ( N = 901) and submitted to factor analyses. An identifiable parental burnout syndrome including four dimensions was found (exhaustion in one's parental role, contrast with previous parental self, feelings of being fed up with one's parental role and emotional distancing from one's children). The resulting instrument, the Parental Burnout Assessment (PBA) presents good validity. Factorial invariance across gender and languages was also found. Finally, the results of this study replicate previous findings that psychological traits of the parents, parenting factors, and family functioning account for more variance in parental burnout than sociodemographic factors.

To field test a parental self-efficacy scale regarding its acceptability and feasibility and to describe parental self-efficacy in a convenience sample of parents with children aged 6 years old or less. Self-care within families is increasingly emphasised in health policy as a means of maximising healthcare resources. This study reports the field testing of a scale designed to measure parental self-efficacy. Cross-sectional survey of parents of children aged 6 years old or less. Subjects were recruited through a parenting internet website (n = 84) and local parenting and community organisations (n = 68) and asked to complete a questionnaire containing the scale. Data collection took place between January and August 2011. The scale, previously validated with an expert panel of professionals, gathered information about parental self-efficacy when administered either directly or through an on-line data collection portal, although there were more missing data when administered via the Internet. Although convenience and self-selecting samples precluded parameter estimation, areas of concern highlighted were difficulties differentiating children with serious illnesses and the use of the Personal Child Health Record. Use of the Internet was widespread, as was use of community pharmacists and nursery staff. Although the primary purpose was not to collect specific data, the data indicated the continuing concern of parents regarding serious illness and where additional investment may be required to meet parental needs and expectations. The previously validated scale can be used to collect information about parental self-efficacy either through a paper questionnaire or the Internet. Although there was slightly more missing data from the Internet version, the ease of its administration makes this an attractive option. Parents generally reported high levels of self-efficacy and satisfaction with services; however, the scale was able to identify areas where further investment

Predicting child physical activity and screen time: parental support for physical activity and general parenting styles.

To examine relationships between parenting styles and practices and child moderate-to-vigorous physical activity (MVPA) and screen time. Participants were children (6.9 ± 1.8 years) with a body mass index in the 70-95th percentile and their parents (421 dyads). Parent-completed questionnaires assessed parental support for child physical activity (PA), parenting styles and child screen time. Children wore accelerometers to assess MVPA. Parenting style did not predict MVPA, but support for PA did (positive association). The association between support and MVPA, moreover, varied as a function of permissive parenting. For parents high in permissiveness, the association was positive (greater support was related to greater MVPA and therefore protective). For parents low in permissiveness, the association was neutral; support did not matter. Authoritarian and permissive parenting styles were both associated with greater screen time. Parenting practices and styles should be considered jointly, offering implications for tailored interventions. © The Author 2014.

Parental influence on child food intake is typically conceptualized at three levels-parenting practices, feeding style, and parenting style. General parenting style is modeled at the most distal level of influence and food parenting practices are conceptualized as the most proximal level of influence. The goal of this article is to provide insights into contents and explanatory value of instruments that have been applied to assess food parenting practices, feeding style, and parenting style. Measures of food parenting practices, feeding style, and parenting style were reviewed, compared, and contrasted with regard to contents, explanatory value, and interrelationships. Measures that are used in the field often fail to cover the full scope and complexity of food parenting. Healthy parenting dimensions have generally been found to be positively associated with child food intake (i.e., healthier dietary intake and less intake of energy-dense food products and sugar-sweetened beverages), but effect sizes are low. Evidence for the operation of higher-order moderation has been found, in which the impact of proximal parental influences is moderated by more distal levels of parenting. Operationalizing parenting at different levels, while applying a contextual higher-order moderation approach, is advocated to have surplus value in understanding the complex process of parent-child interactions in the area of food intake. A research paradigm is presented that may guide future work regarding the conceptualization and modeling of parental influences on child dietary behavior.

This study assessed whether aspects of maternal mental health and well-being were associated with objective monitor-based measures of child's physical activity (PA) and sedentary behavior (SB) and the extent to which household structure (i.e., single- vs multigenerational/dual-parent) and maternal employment (i.e., full-time vs not full-time) moderated those associations. Dyads (N = 191) of mothers and their 8- to 12-year-old children participated in the baseline wave of the Mother's and Their Children's Health study. Mothers (Mage = 40.9 yr [SD = 6.1]; 49% Hispanic) completed a battery of questionnaires to assess maternal mental health and well-being (i.e., self-esteem, life satisfaction, depressive symptoms, anxiety, perceived stress, parenting stress, financial stress, and life events stress). Children (Mage = 9.6 yr [SD = 0.9]; 54% Hispanic; 51% girls) wore an accelerometer across 1 week during waking hours to objectively measure moderate-to-vigorous PA (MVPA) and SB. In single-parent families (n = 47), but not multigenerational/dual-parent families, mothers' parenting stress was negatively associated with child's MVPA (β = -.34, p = .02). In corrected analyses, all other aspects of maternal mental health and well-being were not related to children's activity patterns. Parenting stress was the only maternal mental health variable associated with objective monitor-based measures of child's PA after adjusting for multiple comparisons. Results indicated weaker associations between maternal mental health and well-being and child's MVPA and SB than previously identified using subjective measures of behavior. Study findings support the need to use objective measurements of child's activity patterns to minimize potential confounding because of maternal report in evaluating child's PA and SB.

Childhood central nervous system tumor survivors (CCNSTS) are at risk for adverse health issues. Little research has been conducted to explore the role of parental factors in weight management to mitigate adverse health outcomes. We conducted 9 group interviews (n=20) with CCNSTS, their parents, and health care providers to ascertain parental factors that may influence weight management practices in CCNSTS. Three main themes were identified: parenting style, parent-child connectedness, and food and physical activity (PA) environment. Although most parents adopted an authoritative parenting style related to diet and PA practices, some adopted a permissive parenting style. Participants expressed high levels of connection that may hinder the development of peer relationships and described the food and PA environments that promote or hinder weight management through parental modeling of healthy eating and PA and access to healthy food and activities. Weight management interventions for CCNSTS may experience greater benefit from using a family-focused approach, promoting positive food and PA environments, parental modeling of healthy eating and exercise, and partnering with youth to adopt weight management behaviors.

Abstract Background Parental influence on child food intake is typically conceptualized at three levels—parenting practices, feeding style, and parenting style. General parenting style is modeled at the most distal level of influence and food parenting practices are conceptualized as the most proximal level of influence. The goal of this article is to provide insights into contents and explanatory value of instruments that have been applied to assess food parenting practices, feeding style, and parenting style. Methods Measures of food parenting practices, feeding style, and parenting style were reviewed, compared, and contrasted with regard to contents, explanatory value, and interrelationships. Results Measures that are used in the field often fail to cover the full scope and complexity of food parenting. Healthy parenting dimensions have generally been found to be positively associated with child food intake (i.e., healthier dietary intake and less intake of energy-dense food products and sugar-sweetened beverages), but effect sizes are low. Evidence for the operation of higher-order moderation has been found, in which the impact of proximal parental influences is moderated by more distal levels of parenting. Conclusions Operationalizing parenting at different levels, while applying a contextual higher-order moderation approach, is advocated to have surplus value in understanding the complex process of parent–child interactions in the area of food intake. A research paradigm is presented that may guide future work regarding the conceptualization and modeling of parental influences on child dietary behavior. PMID:23944921

232Th(d,4n)230Pa cross-section measurements at ARRONAX facility

Full text of publication follows. The ARRONAX cyclotron [Ref.1], acronym for 'Accelerator for Research in Radiochemistry and Oncology at Nantes Atlantique' is a new facility installed in Nantes, France. A dedicated program has been launched on production of innovative radionuclides for PET imaging and for β- and α- targeted radiotherapy using proton or α particle. Since the accelerator is also able to deliver deuteron beams up to 35 MeV, we have reconsidered the possibility to use them to produce medical isotopes. In this study, we have focused on cross section measurements using the stacked-foil technique [Ref. 2] of one isotope dedicated to alpha radio-immunotherapy (α RIT) [Ref.3], 226 Th which can be produced through different routes. It's of great interest since it has been found to be a more potent alpha particle emitter for leukemia therapies than Bi 213 [Ref.4]. Indeed, the 226 Th decay produced a cascade of four α particles with a cumulated energy of 27.7 MeV. An additional interest is the possible use of a radionuclide generator system 230 U/ 226 Th. 230 U could be produced directly via 231 Pa(p, 2n) 230 U, and indirectly via 230 Pa using proton or deuteron beams through 232 Th(p, 3n) 230 Pa → 230 U, 232 Th(d, 4n) 230 Pa → 230 U. Twelve data sets are published concerning the 230 Pa cross section induced by proton [Ref 5], only one by deuteron [Ref.6]. As sometimes deuteron induced reaction gives higher cross section values, it seems interesting to focus our study on their use as projectile on 232 Th target to produce 230 Pa. Contaminants created during irradiation are also measured since a good optimization of the process is supposed to find the best compromise between production yield and purity of the final product. Our new sets of data are compared with the existing data [Refs.5,6] on other existing production routes and with results given by TALYS code calculations [Ref.7]. References: 1] F.

Full Text Available Parents play a critical role in developing and shaping their children’s physical activity (PA and sedentary behaviours, particularly in the early years of life. The aim of this systematic review is to identify current literature investigating associations of parental influences with both PA and screen time in young children. This systematic review was conducted in November 2013 using 6 electronic databases covering research literature from January 1998 to November 2013. Thirty articles that met inclusion criteria were identified. These studies covered five important aspects of parenting: (1 parenting practices; (2 parents’ role modelling; (3 parental perceptions of children’s PA and screen viewing behaviours; (4 parental self-efficacy; and (5 general parenting style. Findings suggest that parents’ encouragement and support can increase children’s PA, and reducing parents’ own screen time can lead to decreased child screen time. Improving parenting practices, parental self-efficacy or changing parenting style may also be promising approaches to increasing PA time and decreasing screen time of young children.

Full Text Available Abstract Background The prevalence and level of overweight in childhood is rapidly increasing. One potential contributor to the rise in overweight is a decline in physical activity (PA. The purpose of this study was to compare levels and patterns of PA and PA related personality in normal-weight (NW and overweight (OW 6- to 10-yr-old children. Methods Subjects were grouped into OW (N = 59, BMI = 24.2 ± 4.8 kg/m2 or NW (N = 61, BMI = 15.7 ± 1.5 kg/m2 according to International Obesity Task Force cut-offs. PA was assessed by accelerometry. Parents filled in a questionnaire on PA and sedentary behaviour and PA related personality of their child (born tired, moves slowly, is often tired, lacks energy, avoids physical efforts, prefers watching playing children instead of joining them, is always active, needs to let himself/herself go, has a lot of energy. Results NW children spent on average 77 min/day in MVPA, whereas OW children only 57 min/day (p = .001. OW children had fewer 5, 10 and 20 min bouts of MVPA (p = .01. OW and NW children showed identical PA patterns on both week days and weekends, although at different levels. According to parents' report, a greater percentage of OW children was not engaged in any sport (46% versus 23%, chi2 = 6.3, p = .01. OW children had a less active personality (p Conclusion The results of this study demonstrate that NW children spent on average 20 min per day more in MVPA. PA patterns were similar in NW versus OW children, although at different levels. Greatest differences in PA according to weight status were found in the afternoon during after school hours. This is the first study to show distinct PA related personality traits in OW children compared to NW peers.

Parents have a fundamental role in promoting the healthy weight of their children. To determine parental perceptions of their child's body weight, eating and physical activity (PA) behaviours, and to test a predictive model of parental perceptions regarding their child's PA and healthy eating behaviours. A random-digit telephone survey was conducted among parents of children four to 12 years of age living in the Champlain region of Ontario. Descriptive statistics were used to summarize the responses. Path analysis was used to identify predictors of parental perceptions of PA and healthy eating. The study sample consisted of 1940 parents/caregivers. Only 0.2% of parents reported their child as being obese; 8.6% reported their child as being overweight. Most parents perceived their child to be physically active and eating healthily. Approximately 25% of parents reported that their child spent 2 h/day or more in front of a screen, and that their child consumed less than three servings of fruits and vegetables daily, and regularly consumed fast food. Variables that correlated with PA perceptions included time spent reading/doing homework, interest in PA, perceived importance of PA, frequency of PA, level of parental PA, participation in organized sport, child weight and parental concern for weight. Variables that predicted perceptions regarding healthy eating were parental education, household income, preparation of home-cooked meals, fruit and vegetable intake, and concern for and influence on the child's weight. Parents in the present study sample did not appear to understand, or had little knowledge of the recommendations for PA and healthy eating in children. Parents appeared to base their judgment of healthy levels of PA or healthy eating behaviours using minimal criteria; these criteria are inconsistent with those used by health professionals to define adequate PA and healthy eating. The present survey highlights an important knowledge gap between scientific

Theory-based interventions to promote physical activity (PA) are more effective than atheoretical approaches; however, the comparative utility of theoretical models is rarely tested in longitudinal designs with multiple time points. Further, there is limited research that has simultaneously tested social-cognitive models with self-report and objective PA measures. The primary aim of this study was to test the predictive ability of three theoretical models (social cognitive theory, theory of planned behaviour, and protection motivation theory) in explaining PA behaviour. Participants were adults with type 2 diabetes (n = 287, 53.8% males, mean age = 61.6 ± 11.8 years). Theoretical constructs across the three theories were tested to prospectively predict PA behaviour (objective and self-report) across three 6-month time intervals (baseline-6, 6-12, 12-18 months) using structural equation modelling. PA outcomes were steps/3 days (objective) and minutes of MET-weighted PA/week (self-report). The mean proportion of variance in PA explained by these models was 6.5% for objective PA and 8.8% for self-report PA. Direct pathways to PA outcomes were stronger for self-report compared with objective PA. These theories explained a small proportion of the variance in longitudinal PA studies. Theory development to guide interventions for increasing and maintaining PA in adults with type 2 diabetes requires further research with objective measures. Theory integration across social-cognitive models and the inclusion of ecological levels are recommended to further explain PA behaviour change in this population. Statement of contribution What is already known on this subject? Social-cognitive theories are able to explain partial variance for physical activity (PA) behaviour. What does this study add? The testing of three theories in a longitudinal design over 3, 6-month time intervals. The parallel use and comparison of both objective and self-report PA measures in testing these

(226)Th (T1/2=31 min) is a promising therapeutic radionuclide since results, published in 2009, showed that it induces leukemia cells death and activates apoptosis pathways with higher efficiencies than (213)Bi. (226)Th can be obtained via the (230)U α decay. This study focuses on the (230)U production using the (232)Th(d,4n)(230)Pa(β-)(230)U reaction. Experimental cross sections for deuteron-induced reactions on (232)Th were measured from 30 down to 19 MeV using the stacked-foil technique with beams provided by the ARRONAX cyclotron. After irradiation, all foils (targets as well as monitors) were measured using a high-purity germanium detector. Our new (230)Pa cross-section values, as well as those of (232)Pa and (233)Pa contaminants created during the irradiation, were compared with previous measurements and with results given by the TALYS code. Experimentally, same trends were observed with slight differences in orders of magnitude mainly due to the nuclear data change. Improvements are ongoing about the TALYS code to better reproduce the data for deuteron-induced reactions on (232)Th. Using our cross-section data points from the (232)Th(d,4n)(230)Pa reaction, we have calculated the thick-target yield of (230)U, in Bq/μA·h. This value allows now to a full comparison between the different production routes, showing that the proton routes must be preferred. Copyright © 2014 Elsevier Inc. All rights reserved.

Altered luminosity functions for relativistically beamed objects. II - Distribution of Lorentz factors and parent populations with complex luminosity functions

International Nuclear Information System (INIS)

Urry, C.M.; Padovani, P.

1991-01-01

In a previous paper, Urry and Shafer (1984) showed that the observed luminosity function (LF) of objects that have part or all of their emission relativistically beamed was a double power law, flat at the faint end and steep at the bright end, so that the ratio of beamed sources to parents was a strong function of luminosity. These calculations are extended here for more realistic LFs required for actual tests of a unified theory of AGN. The observed LF of the beam-dominated objects is generally flatter than the parent LF, so that the number density ratio is a strong function of luminosity and can easily be greater than unity at high luminosities, even for gradual low-luminosity cutoffs in the parent LF. Several characteristic break points can be identified depending on the details of the parent LF. The calculations can be used to test unified theories by predicting the observed LF for aligned objects from the LF of the proposed parent population. 6 refs

The present study aims to increase bicycling and level of physical activity (PA), and thereby promote health in parents of toddlers, by giving access to different bicycle types. There is a need for greater understanding of e-bikes and their role in the transportation network, and further effects on PA levels and health. Moreover, longtail bikes could meet certain practical needs not fulfilled by e-bikes or traditional bikes, hence increased knowledge regarding their feasibility should be obtained. No previous studies have investigated whether providing an e-bike or a longtail bike over an extended period in a sample of parents of toddlers influence objectively assessed amount of bicycling and total PA level, transportation habits, cardiorespiratory fitness, body composition and blood pressure. A randomized cross-over trial will be performed, entailing that participants in the intervention group (n = 18) complete the following intervention arms in random order: (i) three months access to an e-bicycle with trailer for child transportation (n = 6), (ii) three months access to a longtail bicycle (n = 6), and (iii) three months access to a regular bicycle with trailer (n = 6), in total nine months. Also, a control group (n = 18) maintaining usual transportation and PA habits will be included. A convenience sample consisting of 36 parents of toddlers residing in Kristiansand municipality, Southern Norway, will be recruited. Total amount of bicycling (distance and time), total level of PA, and transportation habits will be measured at baseline and in connection to each intervention arm. Cardiorespiratory fitness, body composition and blood pressure will be measured at baseline and post-intervention. Main outcome will be bicycling distance and time spent cycling. New knowledge relevant for the timely issues of public health and environmental sustainability will be provided among parents of toddlers, representing a target group of greatest importance

Hispanic preschoolers are less active than their non-Hispanic peers. As part of a feasibility study to assess environmental and parenting influences on preschooler physical activity (PA) (Niños Activos), the aim of this study was to identify what parents do to encourage or discourage PA among Hispanic 3-5 year old children to inform the development of a new PA parenting practice instrument and future interventions to increase PA among Hispanic youth. Nominal Group Technique (NGT), a structured multi-step group procedure, was used to elicit and prioritize responses from 10 groups of Hispanic parents regarding what parents do to encourage (5 groups) or discourage (5 groups) preschool aged children to be active. Five groups consisted of parents with low education (less than high school) and 5 with high education (high school or greater) distributed between the two NGT questions. Ten NGT groups (n = 74, range 4-11/group) generated 20-46 and 42-69 responses/group for practices that encourage or discourage PA respectively. Eight to 18 responses/group were elected as the most likely to encourage or discourage PA. Parental engagement in child activities, modeling PA, and feeding the child well were identified as parenting practices that encourage child PA. Allowing TV and videogame use, psychological control, physical or emotional abuse, and lack of parental engagement emerged as parenting practices that discourage children from being active. There were few differences in the pattern of responses by education level. Parents identified ways they encourage and discourage 3-5 year-olds from PA, suggesting both are important targets for interventions. These will inform the development of a new PA parenting practice scale to be further evaluated. Further research should explore the role parents play in discouraging child PA, especially in using psychological control or submitting children to abuse, which were new findings in this study.

(1) To measure healthcare activation among low-income parents by language (English/Spanish); and (2) to assess the psychometrics of the Parent-Patient Activation Measure (P-PAM) in the study population. We surveyed parents/guardians of publicly-insured children who were established patients at a pediatrics clinic for ≥6months. Surveys included the Parent-Patient Activation Measure (P-PAM), a 13-item measure adapted from the well-validated Patient Activation Measure (PAM). Of 316 surveys, 68% were completed in Spanish. Mean activation score in the English-language survey group was 79.1 (SD 16.2); mean score in the Spanish-language group was 70.7 (SD 17.9) (pSpanish α=0.93). The P-PAM had acceptable test-retest reliability, but no previously reported PAM factor structure fit the study data adequately for either language. Healthcare activation among low-income parents was greater for parents surveyed in English compared with those surveyed in Spanish. The P-PAM has acceptable reliability and validity in English and Spanish, but a different factor structure than the PAM. Activation as measured by the P-PAM may not have the same associations with or impact on health/healthcare outcomes in pediatrics compared with adults owing to possible measure differences between the P-PAM and PAM.

Vara Cuadrado, J M

1969-07-01

A study of Pa-233 excited levels from the alpha decay of Np-237 and from beta decay of Th-233 has been performed. The alpha decay spectrum was measured with a semiconductor spectrometer of 18 keV effective resolution (FWHM). Over 13 new lines were identified. The gamma ray spectra of Np-237 and Th-233 were obtained with a Ge-Li detector low and medium range energy lines, and with Si-Li detector for the low energy region. A continuous purification method of Np-237 from its comparatively short-lived daughter Pa-233 was applied. A high number of new lines were identified in both spectra. The gamma-gamma coincidence spectra were obtained with INa(T{sub 1}) detectors. (Author) 54 refs.

According to social cognitive theory, self-efficacy is central to behavior change. Consequently, parental self-efficacy (PSE) for influencing children's dietary, physical activity (PA), sedentary, and screen time behaviors is important for child obesity prevention. The aim of this study was to evaluate the psychometric properties of an instrument to measure PSE regarding these behaviors in disadvantaged areas. Parents ( n = 229) of whom 47% had completed secondary school or less, and who participated in the Healthy School Start trial, responded to a 15-item PSE instrument. Children's diet and screen time were measured through parent reports. PA and sedentary behaviors were measured using accelerometers. Construct validity was assessed using exploratory factor analysis (EFA), criterion validity by correlations with child behaviors, and internal consistency by Cronbach's alpha. The EFA yielded three factors: (a) PSE for promoting PA; (b) PSE for limiting intake of unhealthy foods, unhealthy drinks, and screen time; and (c) PSE for promoting intake of fruits and vegetables, all with acceptable to good internal consistency (α = .77-.81). Significant correlations ( p children's dietary ( r s = -.19 to -.29) and screen time ( r = -.29) behaviors and Factor 2, and dietary behaviors and Factor 3 ( r s = .20-.39) but not regarding PA and sedentary behaviors and Factor 1. The instrument demonstrated good construct validity and acceptable to good internal consistency regarding all but PA behaviors. It may be useful for assessing PSE in child obesity prevention interventions in disadvantaged settings after some refinement.

This study examined if parental TV viewing, parental self-efficacy or access to media equipment were associated with TV viewing among UK preschool-aged children. Data were derived from a cross-sectional survey of 252 parents of 3-5-year-old children. Parents reported child and parent TV viewing and the number of TVs, DVDs, computers, games consoles, hand-held games consoles, music players and laptop computers in the home. Parents also completed scales which assessed their self-efficacy to limit the screen viewing (SV) and promote the physical activity (PA) and their own PA self-efficacy. Analysis indicated that around two thirds of the children spent two or more hours per day watching TV while 75 % of parents watched ≥ 2 h of TV per day. Logistic regression models showed that children who had a parent who watched ≥ 2 h of TV per day were over five times more likely to also watch ≥ 2 h of TV per day. Each unit increase in parental self-efficacy to limit SV was associated with a 77 % reduction in the likelihood that the child watched ≥ 2 h of TV per day. Each additional piece of media equipment in the home was associated with a 28 % increase in the likelihood that parents watched ≥ 2 h of TV per day. Family-based interventions focusing on changing access to home media equipment and building parental self-efficacy to reduce child TV viewing could form part of efforts to reduce TV viewing among preschool children.

Correlates of physical activity (PA) are hypothesized to be context and behaviour specific, but there is limited evidence of this in young children. The aim of the current study is to investigate associations between personal, social and environmental factors and objectively measured light and moderate-to-vigorous PA (LPA and MVPA, respectively) in four-year-old children. Cross-sectional data were used from the Southampton Women's Survey, a UK population-based longitudinal study. Four-year old children (n = 487, 47.0% male) had valid PA data assessed using accelerometry (Actiheart) and exposure data collected with a validated maternal questionnaire (including data on child personality, family demographics, maternal behaviour, rules and restrictions, and perceived local environment). Linear regression modelling was used to analyse associations with LPA and MVPA separately, interactions with sex were explored. LPA minutes were greater in children whose mothers reported more PA (vs. inactive: regression coefficient±standard error: 6.70±2.94 minutes), and without other children in the neighbourhood to play with (-6.33±2.44). MVPA minutes were greater in children with older siblings (vs. none: 5.81±2.80) and those whose mothers used active transport for short trips (vs. inactive: 6.24±2.95). Children accumulated more MVPA in spring (vs. winter: 9.50±4.03) and, in boys only, less MVPA with availability of other children in the neighbourhood (-3.98±1.70). Young children's LPA and MVPA have differing associations with a number of social and environmental variables. Interventions targeting PA promotion in young children outside of formal care settings should consider including intensity specific factors.

Full Text Available BACKGROUND: Data on objectively measured physical activity (PA in preschoolers are controversial. Direct accelerometry was performed in children aged 3-6 years, and differences in PA patterns over the course of the week were evaluated. Data were analyzed with gender, BMI, lifestyle, and socioeconomic parameters as covariates. METHODS: PA was measured in 119 children by the SensewearPro® accelerometer and analyzed in the 92 (40 girls that wore it for at least 4 days including one day of the weekend. Median measuring time in this group was 7 consecutive days (median/mean daily measuring time: 23.5 h/d and 21.8 h/d, respectively, corresponding to 834,000 analyzed minutes. PA questionnaires were completed by 103 parents and 87 preschool teachers to collect anthropometric, lifestyle, and socioeconomic data. RESULTS: Median daily PA (MET>3 was 4.3 hours (mean: 4.4 hours. Boys spent an estimated 52 min/week more being very active (MET>6 than girls (95% CI [6, 96] min/week, p = 0.02. PA was lower during the weekend (3.7 h/d compared to weekdays (4.5 h/d, p = 3 × 10(-6, where a 95% CI for the difference is [0.5, 1.0] h/d. PA levels did not differ between overweight/obese children (median 4.7 h/d and normal-weight peers (median 4.2 h/d. Daily media consumption increased with decreasing social class on weekdays (p = 0.05 and during the weekend (p = 0.01, but was not related to the amount of daily PA. A multivariate regression with BMI-SDS as independent variable and gender, age, amount of PA>6 MET, parental BMI, media time and socioeconomic status as explanatory variables revealed that only SES had a significant contribution. CONCLUSION: The negative impact of obesity-promoting factors in older children is rather low for preschoolers, but there is evidently a gradient in PA between weekdays and weekends already in this age group. Weight status of preschoolers is already considerably influenced by SES, but not physical activity levels.

To develop and test the Parental PELICAN Questionnaire, an instrument to retrospectively assess parental experiences and needs during their child's end-of-life care. To offer appropriate care for dying children, healthcare professionals need to understand the illness experience from the family perspective. A questionnaire specific to the end-of-life experiences and needs of parents losing a child is needed to evaluate the perceived quality of paediatric end-of-life care. This is an instrument development study applying mixed methods based on recommendations for questionnaire design and validation. The Parental PELICAN Questionnaire was developed in four phases between August 2012-March 2014: phase 1: item generation; phase 2: validity testing; phase 3: translation; phase 4: pilot testing. Psychometric properties were assessed after applying the Parental PELICAN Questionnaire in a sample of 224 bereaved parents in April 2014. Validity testing covered the evidence based on tests of content, internal structure and relations to other variables. The Parental PELICAN Questionnaire consists of approximately 90 items in four slightly different versions accounting for particularities of the four diagnostic groups. The questionnaire's items were structured according to six quality domains described in the literature. Evidence of initial validity and reliability could be demonstrated with the involvement of healthcare professionals and bereaved parents. The Parental PELICAN Questionnaire holds promise as a measure to assess parental experiences and needs and is applicable to a broad range of paediatric specialties and settings. Future validation is needed to evaluate its suitability in different cultures. © 2015 John Wiley & Sons Ltd.

Schools are in a unique position to ensure that all students meet the current physical activity (PA) recommendations. This study aimed to examine 1st to 3rd grade elementary students' accelerometer measured school day PA in the United States (U.S.) and Finland. The sample consisted of 200 students (107 girls, 93 boys; ages 6 to 8) and their school day PA was monitored with hip-worn ActiGraph GT3X+ accelerometers across a 5-day school week and the thresholds 100 and 2296 count per minute were used to separate sedentary time, light PA, and moderate-to-vigorous PA (MVPA). On an average school day, students were engaged in MVPA for 20.0 min in the U.S. and 24.1 min in Finland. Students' school-day MVPA was 9 to 16 minutes higher during physical education (PE) days compared with non-PE days (U.S: 25.8 vs. 16.6 min/day; Finland: 36.3 vs. 20.1 min/day). Girls had less MVPA and more sedentary time compared with boys in both samples. This study highlights both the role of PE and other school day physical activities in meeting PA guidelines. Policy measures are needed to change the structure of the school day and enhance PA to ensure that students meet the PA recommendations.

The aim of the present study was to investigate if context-specific measures of parental-reported physical activity and sedentary behaviour are associated with objectively measured physical activity and sedentary time in children. Cross-sectional study. Seven European countries taking part in the IDEFICS (Identification and Prevention of Dietary- and Lifestyle-induced Health Effects in Children and Infants) study. Data were analysed from 2-9-year-old children (n 5982) who provided both parental-reported and accelerometer-derived physical activity/sedentary behaviour measures. Parents reported their children's daily screen-time, weekly sports participation and daily outdoor playtime by means of the Outdoor Playtime Checklist (OPC) and Outdoor Playtime Recall Questions (OPRQ). Sports participation, OPC- and OPRQ-derived outdoor play were positively associated with accelerometer-derived physical activity. Television viewing and computer use were positively associated with accelerometer-derived sedentary time. All parental-reported measures that were significantly associated with accelerometer outcomes explained only a minor part of the variance in accelerometer-derived physical activity or sedentary time. Parental-reported measures of physical activity and sedentary behaviour are not useful as a proxy for 2-9-year-old children's physical activity and sedentary time. Findings do not preclude the use of context-specific measures but imply that conclusions should be limited to the context-specific behaviours that are actually measured. Depending on the aim of the study, future research should carefully consider the choice of measurements, including the use of subjective or objective measures of the behaviour of interest or a combination of both.

Despite the unequivocal benefits of regular physical activity, many parents engage in lower levels of physical activity (PA) following the birth of a child. Drawing on the theory of planned behaviour (TPB) and health action process approach (HAPA), an integrative model was developed to examine variables predicting PA in parents of very young children. In addition, key beliefs related to PA intentions and behaviour among parents of very young children were investigated. A prospective-correlational design with two waves of data collection, spaced one week apart, was adopted. Parents (N = 297) completed an online- or paper-based questionnaire assessing TPB global constructs and belief-based items as well as family social support and planning from the HAPA. One week later, parents self-reported their PA behaviour. Data were analysed using latent variable structural equation modelling. Findings revealed the model was a good fit to the data, accounting for 62% and 27% of the variance in PA intentions and behaviour, respectively. Attitude, subjective norm, and perceived behavioural control predicted intentions. Family social support failed to predict both planning and intentions. Physical activity was predicted by planning only, with an indirect effect occurring from intentions to behaviour through planning. A number of key beliefs on intentions and behaviour were also identified. This formative research provides further understanding of the factors that influence the PA behaviour of parents of very young children. Results provide targets for future interventions to increase PA for parents in a transition phase where PA levels decline. Statement of Contribution What is already known on this subject? Despite physical activity benefits, many parents are inactive following the birth of a child Social-cognitive models have demonstrated efficacy in predicting physical activity Weaknesses are inherent in the use of single theories to explain behaviour What does this study

The beneficial effect of physical activity (PA) on mental health in adults is well established, but less is known about this relationship in children. We examine associations between objectively measured sedentary time, PA and mental health in 11-year-olds from the UK Millennium Cohort Study (MCS). Longitudinal data from MCS sweeps 4 (age 7) and 5 (age 11) were used (n=6153). Accelerometer data were collected at MCS4, and mental health was measured at MCS4 and MCS5 using subscales (peer, emotional, conduct, hyperactivity) of the Strengths and Difficulties Questionnaire (SDQ). Associations between mean daily PA minutes at different intensities (sedentary, light, moderate-to-vigorous) at MCS4 and SDQ outcomes at MCS5 (score range 0-10) were estimated using multiple linear regression models, adjusting for SDQ at MCS4 and individual and family characteristics, and stratified by gender. In fully adjusted models, increased PA at MCS4 was associated with fewer peer problems in boys and girls at MCS5. For each additional 15 min in moderate-to-vigorous physical activity (MVPA), peer problems decreased -0.077 points (95% CI -0.133 to -0.022) in boys. For girls, light PA was associated with decreased peer problems (-0.071 points/30 min, 95% CI -0.130 to -0.013). Greater sedentary time was associated with more peer problems and fewer hyperactivity symptoms in boys and girls. Increased MVPA was associated with more conduct and hyperactivity problems in boys and more hyperactivity in girls. Increased sedentary time is associated with more peer problems in children, and PA, generally, is beneficial for peer relations in children aged 11. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Full Text Available Abstract Background Parental reports are often used in large-scale surveys to assess children's body mass index (BMI. Therefore, it is important to know to what extent these parental reports are valid and whether it makes a difference if the parents measured their children's weight and height at home or whether they simply estimated these values. The aim of this study is to compare the validity of parent-reported height, weight and BMI values of preschool children (3-7 y-old, when measured at home or estimated by parents without actual measurement. Methods The subjects were 297 Belgian preschool children (52.9% male. Participation rate was 73%. A questionnaire including questions about height and weight of the children was completed by the parents. Nurses measured height and weight following standardised procedures. International age- and sex-specific BMI cut-off values were employed to determine categories of weight status and obesity. Results On the group level, no important differences in accuracy of reported height, weight and BMI were identified between parent-measured or estimated values. However, for all 3 parameters, the correlations between parental reports and nurse measurements were higher in the group of children whose body dimensions were measured by the parents. Sensitivity for underweight and overweight/obesity were respectively 73% and 47% when parents measured their child's height and weight, and 55% and 47% when parents estimated values without measurement. Specificity for underweight and overweight/obesity were respectively 82% and 97% when parents measured the children, and 75% and 93% with parent estimations. Conclusions Diagnostic measures were more accurate when parents measured their child's weight and height at home than when those dimensions were based on parental judgements. When parent-reported data on an individual level is used, the accuracy could be improved by encouraging the parents to measure weight and height

Conceptual and measurement issues in early parenting practices research: an epidemiologic perspective.

Walker, Lorraine O; Kirby, Russell S

Early parenting practices are significant to public health because of their linkages to child health outcomes. This paper focuses on the current state of the science regarding conceptual frameworks that incorporate early parenting practices in epidemiologic research and evidence supporting reliability and validity of self-report measures of such practices. Guided by a provisional definition of early parenting practices, literature searches were conducted using PubMed and Sociological Abstracts. Twenty-five published studies that included parent-report measures of early parenting practices met inclusion criteria. Findings on conceptual frameworks were analyzed qualitatively, whereas evidence of reliability and validity were organized into four domains (safety, feeding and oral health, development promotion, and discipline) and summarized in tabular form. Quantitative estimates of measures of reliability and validity were extracted, where available. We found two frameworks incorporating early parenting: one a program theory and the other a predictive model. We found no reported evidence of the reliability or validity of parent-report measures of safety or feeding and oral health practices. Evidence for reliability and validity were reported with greater frequency for development promotion and discipline practices, but report of the most pertinent type of reliability estimation, test-retest reliability, was rare. Failure to examine associations of early parenting practices with any child outcomes within most studies resulted in missed opportunities to indirectly estimate validity of parenting practice measures. Stronger evidence concerning specific measurement properties of early parenting practices is important to advancing maternal-child research, surveillance, and practice.

While numerous studies have examined the relationships among correlates of physical activity (PA), less attention has been given to identifying the correlates of low PA duration. The main objective of the current study was to examine correlates of low PA duration, team sports participation and smoking behaviors among adolescents. Data from the 2005 Colorado Youth Behavioral Risk Survey were analyzed using Cox proportional hazard models. We evaluated associations between two measures of low PA duration, assessed as per Healthy People 2010 (HP2010) objectives and 2008 Physical Activity Guidelines (PAG) for Americans, and smoking behaviors, participation in the physical education (PE) and team sports, controlling for age, gender and other behavioral characteristics. Forty percent and 70%, respectively, of adolescents did not meet the 2008 PAG and HP2010 objectives. After adjustment, smoking remained associated with failure to meet the 2008 PAG. However, no significant relationship was found with low PA duration as per the HP2010 objectives. The risk of low PA was higher among girls for both outcome measures. Likewise, adolescents who reported no participation in team sports presented a 7-fold higher risk of low PA as per the 2008 PAG and 51% higher risk of low PA as per the HP2010 objectives compared with the group with team sports participation. Regular participation in school PE and team sports may represent an important avenue for increasing PA duration and reducing smoking behaviors among adolescents.

Uranium age determination - Separation and analysis of 230Th and 231Pa

International Nuclear Information System (INIS)

Morgenstern, A.; Apostolidis, C.; Mayer, K.; Wallenius, M.

uranium must be of high chemical recovery and must afford large decontamination factors. In general, the age obtained from parent/daughter ratios refers to the last separation of the parent nuclide from its daughters, i.e. the last purification of the material. The accuracy of the obtained age therefore depends on the quality of the purification process and assumes that the material subsequently has not been contaminated. Obviously the availability of two analytical methods relying on both, independent parent/daughter pairs will therefore significantly increase the confidence in the experimental results. In this work we demonstrate analytical methods for the age determination of uranium samples using the parent/daughter relations 234 U/ 230 Th and 235 U/ 231 Pa. Thorium is separated from bulk uranium using extraction chromatography and subsequently quantified using □-spectrometry, thermal ionisation mass spectrometry (TIMS) and inductively coupled mass spectrometry (ICP-MS). Protactinium is separated by highly selective sorption of protactinium to silica gel followed by □-spectrometric quantification. The methods were tested and validated using uranium reference materials of different uranium enrichment and of known ages. The experimental results obtained with both methods were found to agree with the assumed ages of the reference materials within the combined uncertainty of the measurement. The analysis exploiting the parent/daughter pair 235 U/ 231 Pa exhibits a slightly larger combined uncertainty and bias than the thorium method but is found valuable in validating the experimental results by means of a second, independent analysis.

There is growing importance of the Parental Bonding Instrument (PBI) in clinical practice and research on parenting and parental bonding. Since the development of this diagnostic tool (Parker et al., Brit. J. Med. Psycho.1979; 52:1-10), a number of validation studies have been done in various cultures. The aim of the present study was to translate the measure into Bangla and validate in Bangladeshi culture. A total of 200 adolescents participated in the study. Exploratory factor analysis (EFA) of the data from 191 participants (who provided complete responses) identified a two-factor (Care and Overprotection) structure of the PBI with 17 items. The two factors together explained 44.18% of the total variance. The factors showed moderate to very high internal consistency (Cronbach's α=0.863 for Care; 0.622 for Overprotection), and very strong convergent and discriminant validity as evident by their correlations with the measures of cognitive distortions and antisocial behaviors. In line with the original tool we defined four types of parenting style, such as Affectionate constraint, Affectionless control, Optimal parenting, and Neglectful parenting. This study opens the door of future research on parenting practices and parent-child relationships in Bangladesh. Copyright © 2016 Elsevier B.V. All rights reserved.

Adopting the milliliter as the preferred unit of measurement has been suggested as a strategy to improve the clarity of medication instructions; teaspoon and tablespoon units may inadvertently endorse nonstandard kitchen spoon use. We examined the association between unit used and parent medication errors and whether nonstandard instruments mediate this relationship. Cross-sectional analysis of baseline data from a larger study of provider communication and medication errors. English- or Spanish-speaking parents (n = 287) whose children were prescribed liquid medications in 2 emergency departments were enrolled. Medication error defined as: error in knowledge of prescribed dose, error in observed dose measurement (compared to intended or prescribed dose); >20% deviation threshold for error. Multiple logistic regression performed adjusting for parent age, language, country, race/ethnicity, socioeconomic status, education, health literacy (Short Test of Functional Health Literacy in Adults); child age, chronic disease; site. Medication errors were common: 39.4% of parents made an error in measurement of the intended dose, 41.1% made an error in the prescribed dose. Furthermore, 16.7% used a nonstandard instrument. Compared with parents who used milliliter-only, parents who used teaspoon or tablespoon units had twice the odds of making an error with the intended (42.5% vs 27.6%, P = .02; adjusted odds ratio=2.3; 95% confidence interval, 1.2-4.4) and prescribed (45.1% vs 31.4%, P = .04; adjusted odds ratio=1.9; 95% confidence interval, 1.03-3.5) dose; associations greater for parents with low health literacy and non-English speakers. Nonstandard instrument use partially mediated teaspoon and tablespoon-associated measurement errors. Findings support a milliliter-only standard to reduce medication errors.

Low socio-economic environmental determinants of children's physical activity in Coventry, UK: A Qualitative study in parents.

Science.gov (United States)

Eyre, E L J; Duncan, M J; Birch, S L; Cox, V M

2014-01-01

Children's physical activity (PA) is affected by socio-economic status (SES) and the environment. Children are not fully autonomous in their decision making; parental decisions thus affect how children utilise their surrounding environments for PA. The aim was to examine environmental influences on children's PA from a qualitative perspective in parents from low SES wards in Coventry, UK. 59 parents of children in year 4 (aged 8-9years) completed the ALPHA environmental questionnaire. 16 of these parents took part in focus group discussions examining environmental facilitators and barriers to their child's PA (March-April, 2013). Emerging themes related to physical (i.e. poor access, safety and quality of the neighbourhood) and social environment (i.e. 'rough' neighbourhood due to crime and anti-social behaviour) influences on the PA behaviour of children. The parents believed these environmental factors resulted in the children engaging in greater sedentary activity (watching TV) indoors. The school environment was perceived as a supportive physical environment for children's PA behaviour. Parent's perceptions of an unsupportive physical and social environment restrict children's opportunities to play outside and be physically active and may lead to increased body fat (BF). Schools provide a supportive environment for children from low SES to be physically active in.

Affected parents often have limited access to information and support and appropriate health care services. While scales to measure the needs of parents of children with chronic illnesses have been developed, there have been no previous attempts to develop a scale to assess the needs of parents of children with rare diseases. Objective: To develop a scale for measuring the supportive care needs of parents of children with rare diseases. Method: A total of 301 responses to our Parental Needs Survey were randomly divided into two halves, one for exploratory factor analysis and the other for confirmatory factor analysis (CFA. After removing unsuitable items, exploratory factor analysis was undertaken to determine the factor structure of the data. CFA using structural equation modeling was then undertaken to confirm the factor structure. Results: Seventy-two items were entered into the CFA, with a scree plot showing a likely four-factor solution. The results provided four independent subscales of parental needs: Understanding the disease (four items; Working with health professionals (four items; Emotional issues (three items; and Financial needs (three items. The structural equation modeling confirmed the suitability of the four-factor solution and demonstrated that the four subscales could be added

Parent-reported measures of child health and wellbeing in same-sex parent families: a cross-sectional survey

Science.gov (United States)

2014-01-01

Background It has been suggested that children with same-sex attracted parents score well in psychosocial aspects of their health, however questions remain about the impact of stigma on these children. Research to date has focused on lesbian parents and has been limited by small sample sizes. This study aims to describe the physical, mental and social wellbeing of Australian children with same-sex attracted parents, and the impact that stigma has on them. Methods A cross-sectional survey, the Australian Study of Child Health in Same-Sex Families, was distributed in 2012 to a convenience sample of 390 parents from Australia who self-identified as same-sex attracted and had children aged 0-17 years. Parent-reported, multidimensional measures of child health and wellbeing and the relationship to perceived stigma were measured. Results 315 parents completed the survey (completion rate = 81%) representing 500 children. 80% of children had a female index parent while 18% had a male index parent. Children in same-sex parent families had higher scores on measures of general behavior, general health and family cohesion compared to population normative data (β = 2.93, 95% CI = 0.35 to 5.52, P = .03; β = 5.60, 95% CI = 2.69 to 8.52, P = mental health, and family cohesion were all negatively associated with increased stigma (β = -3.03, 95% CI = -5.86 to -0.21, P = .04; β = -10.45, 95% CI = -18.48 to -2.42, P = .01; and β = -9.82, 95% CI = -17.86 to -1.78, P = .02 respectively) and the presence of emotional symptoms was positively associated with increased stigma (β =0.94, 95% CI = 0.08 to 1.81, P = .03). Conclusions Australian children with same-sex attracted parents score higher than population samples on a number of parent-reported measures of child health. Perceived stigma is negatively associated with mental health. Through improved awareness of stigma these findings play an important role in

Early diagnosis of Turner syndrome (TS) is necessary to facilitate appropriate management, including growth promotion. Not all girls with TS have overt short stature, and comparison with parental height (Ht) is needed for appropriate evaluation. We examined both the prevalence and diagnostic sensitivity of measured parental Ht in a dedicated TS clinic between 1989 and 2013. Lower end of parental target range (LTR) was calculated as mid-parental Ht (correction factor 12.5 cm minus 8.5 cm) and converted to standard deviation scores (SDS) using UK 1990 data, then compared with patient Ht SDS at first accurate measurement aged > 1 year. Information was available in 172 girls of whom 142 (82.6%) were short at first measurement. However, both parents had been measured in only 94 girls (54.6%). In 92 of these girls age at measurement was 6.93 ± 3.9 years, Ht SDS vs LTR SDS - 2.63 ± 0.94 vs - 1.77 ± 0.81 (p Turner syndrome are short in relation to parental heights, with untreated final height approximately 20 cm below female population mean. • Measured parental height is more accurate than reported height. What is New: • In a dedicated Turner clinic, there was 85% sensitivity when comparing patient height standard deviation score at first accurate measurement beyond 1 year of age with the lower end of the parental target range standard deviation. • However, measured height in both parents had been recorded in only 54.6% of the Turner girls attending the clinic. This indicates the need to improve the quality of growth assessment in tertiary care.

Correspondence of perceived vs. objective proximity to parks and their relationship to park-based physical activity

Kaczynski Andrew T

2009-08-01

Full Text Available Abstract Background Parks are key environmental resources for encouraging population-level physical activity (PA. In measuring availability of parks, studies have employed both self-reported and objective indicators of proximity, with little correspondence observed between these two types of measures. However, little research has examined how the degree of correspondence between self-reported and objectively-measured distance to parks is influenced by individual, neighborhood, and park-related variables, or which type of measure is more strongly related to physical activity outcomes. Methods We used data from 574 respondents who reported the distance to their closest park and compared this with objective measurements of proximity to the closest park. Both indicators were dichotomized as having or not having a park within 750 m. Audits of all park features within this distance were also conducted and other personal characteristics and neighborhood context variables (safety, connectedness, aesthetics were gleaned from participants' survey responses. Participants also completed detailed seven-day PA log booklets from which measures of neighborhood-based and park-based PA were derived. Results Agreement was poor in that only 18% of respondents achieved a match between perceived and objective proximity to the closest park (kappa = 0.01. Agreement was higher among certain subgroups, especially those who reported engaging in at least some park-based PA. As well, respondents with a greater number of parks nearby, whose closest park had more features, and whose closest park contained a playground or wooded area were more likely to achieve a match. Having a ball diamond or soccer field in the closest park was negatively related to achieving a match between perceived and objective proximity. Finally, engaging in at least some park-based PA was not related to either perceived or objective proximity to a park, but was more likely when a match between and

Previous studies have shown that children who spend more time outdoors are more active and spend less time sedentary, but these studies were limited by the use of small convenience samples. We examined the relationship between outdoor time and measures of physical activity (PA), screen time and sedentary time in a nationally-representative sample of young children. Parental reports of outdoor time were obtained for 594 children aged 3-6 years (47.8% girls) who participated in the 2012-2013 Canadian Health Measures Survey. Participants were asked to wear an Actical accelerometer for seven consecutive days. Outdoor time and screen time were assessed by parent reports. The relationships between outdoor time and measures of PA, screen time and sedentary time were examined with linear regression models. Adherence to PA guidelines was estimated based on a betabinomial distribution, and adherence with the screen time guidelines was assessed through logistic regression models. All analyses were stratified by age group (3-4 and 5-6 year olds) and adjusted for sex, parental education and household income. Among 5-6 year olds, each additional hour spent outdoors was associated with an additional 10 minutes of moderate-to-vigorous PA (95% CI: 6-14), 27,455 more accelerometer counts/day (95% CI: 11,929-42,980) and an increased likelihood of meeting the PA guidelines (OR = 2.53; 95% CI: 1.68-3.82). No significant relationships were observed among 3-4 year olds. Outdoor time has a large effect on PA among 5-6 year olds at a population level. Future studies should examine the correlates of outdoor time to inform novel PA promotion interventions.

The strategic plan for the next E-Area Low-Level Waste Facility Performance Assessment includes recommended changes to the screening criteria used to reduce the number of radioisotopes that are to be considered in the air and radon pathways incorporated into the GoldSim® atmospheric release model (ARM). For the air pathway, a revised screening methodology was developed based on refinement of previous E-Area PA screening approaches and consideration of the strategic plan recommendations. The revised methodology has three sequential screening steps for each radioisotope: (1) volatility test using the Periodic Table of the Elements, (2) stability test based on half-life, and (3) stability test based on volatility as measured by the Henry’s Law constant for the assumed dominant gaseous species or vapor pressure in the case of tritiated water. Of the 1252 radioisotopes listed in the International Commission on Radiological Protection Publication 107, only the 10 that satisfied all three steps of the revised screening methodology will be included in the ARM. They are: Ar-37, Ar-39, Ar-42, C-14, H-3, Hg-194, Hg-203, Kr-81, Kr-85, and Xe-127. For the radon pathway, a revised screening methodology was developed that also has three sequential steps: (1) identify all decay chains that terminate at Rn-222, (2) screen out parents that decay through U-238 because of its 4.5-billion-year primordial half-life, and (3) eliminate remaining parents whose half-life is shorter than one day. Of the 86 possible decay chains leading to Rn-222, six decay chains consist of 15 unique radioisotopes that will be incorporated into the ARM. The 15 radioisotopes are: U-238, Th-234, Pa-234m, Pu-238, U-234, Th-230, Ra-226, Cf-246, Cm-242, Am-242m, Am-242, Np-238, Np-234, Pa-230, and Rn-222.

2014-01-01

Conceptually and methodologically distinct models exist for assessing quality of parent-child relationships, but few studies contrast competing models or assess their overlap in predicting developmental outcomes. Using observational methodology, the current study examined the distinctiveness of attachment theory-based and social learning theory-based measures of parenting in predicting two key measures of child adjustment: security of attachment narratives and social acceptance in peer nominations. A total of 113 5-6-year-old children from ethnically diverse families participated. Parent-child relationships were rated using standard paradigms. Measures derived from attachment theory included sensitive responding and mutuality; measures derived from social learning theory included positive attending, directives, and criticism. Child outcomes were independently-rated attachment narrative representations and peer nominations. Results indicated that Attachment theory-based and Social Learning theory-based measures were modestly correlated; nonetheless, parent-child mutuality predicted secure child attachment narratives independently of social learning theory-based measures; in contrast, criticism predicted peer-nominated fighting independently of attachment theory-based measures. In young children, there is some evidence that attachment theory-based measures may be particularly predictive of attachment narratives; however, no single model of measuring parent-child relationships is likely to best predict multiple developmental outcomes. Assessment in research and applied settings may benefit from integration of different theoretical and methodological paradigms.

Full Text Available Introduction: To examine temporal variations in parental and peer influences on adolescent physical activity (PA and whether these variations predicted changes in PA. Methods: We analyzed data from Years 1, 2 and 3 of the COMPASS study. Participants were 22 909 students in Grades 9 to 12 (mean age [years] = 15.42 ± 1.12, 46% boys, 85% White, who had completed the following survey items on 2 or more consecutive occasions: age, sex, grade, race/ethnicity, moderate-to-vigorous physical activity (MVPA, parental encouragement and parental instrumental support for PA, and number of active peers. We used a linear-mixed model to investigate longitudinal effects of parental and peer influences on changes in square-root transformed average MVPA. We used a generalized-estimating-equations (GEE model to investigate compliance with Canadian PA guidelines for youth. These models included parental encouragement, instrumental support and number of active peers as time-varying predictors, adjusting for sociodemographic factors and grade as covariates, and accounting for the clustering within children and schools. Results: We found that adolescents perceived significantly less parental encouragement and instrumental support and reported fewer active peers as they got older. In addition, the adjusted models suggest that, for a one-unit increase in the score of parental encouragement, parental instrumental support and number of active peers, average MVPA significantly increased by 0.22 units, 0.23 units and 0.16 units, respectively. For the same one-unit increase, adjusted odds of an adolescent complying with the PA guidelines increased by 9%, 4% and 6%, respectively. Conclusion: Promoting parental support and facilitating the formation and maintenance of a physically active friendship network may play an important role in attenuating declines in PA during adolescence.

Abstract Background Parent-focused interventions may help to reduce youth screen-viewing (SV). This review synthesized current information on the links between parenting styles, parenting practices, and youth SV with a focus on measurement. Methods A systematic review of electronic databases was conducted. Results In all, 29 of 1189 studies met the inclusion criteria. Parenting practices were divided into rule and nonrule-based practices. Seven rules: (1) Limits on total time (n studies=23); (2) limits on time of day (n=7); (3) content restriction (n=11); (4) mealtime rules (n=2); (5) parental supervision (n=3); (6) contingent screentime (n=3); and (7) no-TV policy (n=1) were reported. Two nonrule-based practices were reported: Co-viewing (n=6) and encouragement to view (n=2). Three studies (10.3%) provided information on parenting styles. Only 12 studies (41.4%) provided information on the reliability/validity of the outcome measure, 15 (51.7%) studies provided information on the reliability/validity of the parenting measure, and 6 (20.7%) provided information on the reliability/validity of both outcome and exposure measures. Conclusions There is mixed evidence that parenting styles and media-related parenting practices are associated with youth SV. The assessment of parental influence of youth media use is hampered by the diversity of measures that have been used. There is a need for new measures that assess a range of media parenting practices that are relevant to multiple forms of SV. PMID:23944925

Asian American parenting is often portrayed as highly controlling and even harsh. This study empirically tested the associations between a set of recently developed Korean ga-jung-kyo-yuk measures and several commonly used Western parenting measures to accurately describe Asian American family processes, specifically those of Korean Americans. The results show a much nuanced and detailed picture of Korean American parenting as a blend of Western authoritative and authoritarian styles with positive and—although very limited—negative parenting. Certain aspects of ga-jung-kyo-yuk are positively associated with authoritative style or authoritarian style, or even with both of them simultaneously. They were positively associated with positive parenting (warmth, acceptance, and communication) but not with harsh parenting (rejection and negative discipline). Exceptions to this general pattern were Korean traditional disciplinary practices and the later age of separate sleeping of children. The study discusses implications of these findings and provides suggestions for future research. PMID:23977415

Many studies have examined the hypothesis that greater participation in physical activity (PA) is associated with less brain atrophy. Here we examine, in a sub-sample (n=352, mean age 79.1 years) of the Age, Gene/Environment Susceptibility-Reykjavik Study cohort, the association of the baseline and 5-year change in magnetic resonance imaging (MRI)-derived volumes of gray matter (GM) and white matter (WM) to active and sedentary behavior (SB) measured at the end of the 5-year period by a hip-worn accelerometer for seven consecutive days. More GM (β=0.11; p=0.044) and WM (β=0.11; p=0.030) at baseline was associated with more total physical activity (TPA). Also, when adjusting for baseline values, the 5-year change in GM (β=0.14; p=0.0037) and WM (β=0.11; p=0.030) was associated with TPA. The 5-year change in WM was associated with SB (β=-0.11; p=0.0007). These data suggest that objectively measured PA and SB late in life are associated with current and prior cross-sectional measures of brain atrophy, and that change over time is associated with PA and SB in expected directions.

The purpose of this study is to conduct a cross-cultural adaptation of the Assistive Technology Device Predisposition Assessment (ATD PA) for use in Brazil. The selection of the Assistive Technology Device Predisposition Assessment (ATD PA) was determined by previous literature reviews of articles published in 2014 and 2016 in six databases with the terms "assistive device" or "assistive technology" or "self-help device" combined with "evidence-based practice" or "framework" or "measurement scale" or "model and outcome assessment". This review indicated that the conceptual model of Assistive Technology (AT) most discussed in the literature was the Matching Person and Technology (MPT) model, and this finding determined the selection of ATD PA as an assessment within the MPT portfolio of measures. The procedures for cross-cultural adaptation were as follows: Equivalence of Concept, Semantic and Operational. Five experts were asked to translate 725 items and these translations were evaluated and a high level of agreement was demonstrated. The Portuguese version, Avaliação de Tecnologia Assistiva - Predisposição ao Uso - ATD PA Br, was derived from the original version in English (ATD PA). The ATD PA Br will support professionals and people with disabilities in Brazil to better select AT devices according to the clients' needs. Implications for rehabilitation Provides a systematic way of selecting assistive technology devices for the use of individuals with disabilities according to the Brazilian reality. A systematic way of selecting the assistive technology that can help decrease the abandonment of the assistive technology use. The use of the Matching Person and Technology theorical model and of the assessment ATD PA Br is essential to guide the researches and clinical practice in Brazil.

INITIAL VALIDATION OF THE ASSESSMENT OF PARENTING TOOL: A TASK- AND DOMAIN-LEVEL MEASURE OF PARENTING SELF-EFFICACY FOR PARENTS OF INFANTS FROM BIRTH TO 24 MONTHS OF AGE.

Parenting self-efficacy (PSE) includes parents' self-perceptions regarding their capabilities in performing the numerous and changing tasks associated with parenting a specific child (i.e., domain-specific PSE) as well as their self-perceptions in the parenting role overall (i.e., domain-general PSE). Prior literature has demonstrated PSE's relations with numerous constructs significant to mental health and the parent-infant relationship. Prior measures of PSE have been limited by focusing on only domain-specific or domain-general PSE, ignoring the importance of infant development to PSE, and other psychometric limitations. This article presents sound psychometric data for a new measure of PSE, the Assessment of Parenting Tool (APT). The APT includes task-level items on the Domain-Specific subscale (APT-DS) for each age-referenced version of the measure as well as a domain-general subscale that taps overall PSE within the first 24 months' postpartum. Initial construct validity of the measure is established, particularly for parents of infants aged 3 months and older. A stable, three-factor structure for the domain-general subscale includes "coping with being a parent," "attuned parenting," and "self-perceived model parenting." Future directions for the APT, including a revised checklist format for the domain-specific subscale, are included. © 2016 Michigan Association for Infant Mental Health.

2014-02-01

Measuring perioperative behavior changes requires validated objective rating scales. We developed a simple score for children's behavior during induction of anesthesia (Pediatric Anesthesia Behavior score) and assessed its reliability, concurrent validity, and predictive validity. Data were collected as part of a wider observational study of perioperative behavior changes in children undergoing general anesthesia for elective dental extractions. One-hundred and two healthy children aged 2-12 were recruited. Previously validated behavioral scales were used as follows: the modified Yale Preoperative Anxiety Scale (m-YPAS); the induction compliance checklist (ICC); the Pediatric Anesthesia Emergence Delirium scale (PAED); and the Post-Hospitalization Behavior Questionnaire (PHBQ). Pediatric Anesthesia Behavior (PAB) score was independently measured by two investigators, to allow assessment of interobserver reliability. Concurrent validity was assessed by examining the correlation between the PAB score, the m-YPAS, and the ICC. Predictive validity was assessed by examining the association between the PAB score, the PAED scale, and the PHBQ. The PAB score correlated strongly with both the m-YPAS (P risk of developing postoperative behavioral disturbance. This study provides evidence for its reliability and validity. © 2013 John Wiley & Sons Ltd.

Purpose: To investigate the influence of hyperthermia up to 45 deg. C on fibrinolysis with recombinant tissue-type plasminogen activator (rt-PA). Methods: Standardized fibrin clots were incubated in a water bath for 5 hr with either rt-PA (test group) or 0.9% sodium chloride (control group) and blood plasma at temperatures of 30-45 deg. C. Concentrations of D-dimer and time to complete clot lysis were measured.Results: The activity of fibrinolysis with rt-PA rose with increasing temperature: time to lysis approximately halved from 30 deg. C to 40 deg. C and the concentration of D-dimer tripled. In the control group clot size did not change.Conclusions: Activity of rt-PA-induced fibrinolysis rises distinctly with higher temperatures. Since even healthy subjects show a physiologic decline in body temperature in the extremities, in patients with occlusive arterial disease decreased activity of fibrinolysis with rt-PA can be expected. Controlled hyperthermia may improve fibrinolysis with rt-PA and should be investigated in vivo

This aimed to validate measures of constructs included in an extended Health Belief Model (EHBM) addressing oral health beliefs among American Indian (AI) parents. Questionnaire data were collected as part of a randomized controlled trial (n = 1016) aimed at reducing childhood caries. Participants were AI parents with a preschool-age child enrolled in the Navajo Nation Head Start program. Questionnaire items addressed five EHBM constructs: perceived susceptibility, severity, barriers, benefits, and parental self-efficacy. Subscales representing each construct underwent reliability and validity testing. Internal consistency reliability of each subscale was evaluated using Cronbach's alpha. Convergent validity was assessed using linear regression to evaluate the association of each EHBM subscale with oral health-related measures. Internal consistency reliability was high for self-efficacy (α = 0.83) and perceived benefits (α = 0.83) compared to remaining EHBM subscales (α Parents with more education (p parents (ps = 0.02) and those with more education (ps oral health behavior. Female parents (p Parental knowledge was associated with all EHBM measures (ps  0.05). Parents with increased self-efficacy had greater behavioral adherence (p parents who reported higher perceived barriers (p oral health outcomes were associated with higher levels of self-efficacy (p < 0.0001) and lower levels of perceived severity (p = 0.02) and barriers (p = 0.05). Results support the value of questionnaire items addressing the EHBM subscales, which functioned in a manner consistent with the EHBM theoretical framework in AI participants.

Full Text Available Abstract Background Determining the most important demographic correlates of sedentary behavior and physical activity will help identify the groups of children that are most in need of intervention. Little is known in regards to the demographic correlates of sedentary behavior and physical activity in toddlers (aged 12–35 months, where long-term behavioral patterns may initially be formed. Therefore, the objective of this study was to examine the associations between demographic correlates and specific types of sedentary behavior and physical activity in this age group. Methods Findings are based on 149 toddlers (19.0 ± 1.9 months and their parents (33.7 ± 4.7 years recruited from immunization clinics in Edmonton, Canada as part of the Parents’ Role in Establishing healthy Physical activity and Sedentary behavior habits (PREPS project. Toddlers’ and parental demographic characteristics and toddlers’ television viewing, video/computer games, and overall screen time were measured via the PREPS parental questionnaire. Toddlers’ objectively measured sedentary time and physical activity (light, moderate to vigorous, and total were accelerometer-derived using Actigraph wGT3X-BT monitors. Simple and multiple linear regression models were conducted to examine associations. Results In the multiple linear regression models, toddlers’ age, toddlers’ sex (female versus male, toddlers’ race/ethnicity (other versus European-Canadian/Caucasian, and household income ($50,001 to $100,000 versus > $100,000 were significantly positively associated, and main type of child care (child care center versus parental care was significantly negatively associated with screen time. Similar findings were observed with television viewing, except null associations were observed for toddlers’ sex. Toddlers’ race/ethnicity (other versus European-Canadian/Caucasian was significantly positively associated and main type of child care (child care

Adenosine administration is needed for the achievement of maximal hyperaemia fractional flow reserve (FFR) assessment. The objective was to test the accuracy of Pd/Pa ratio registered during submaximal hyperaemia induced by non-ionic contrast medium (contrast FFR [cFFR]) in predicting FFR and comparing it to the performance of resting Pd/Pa in a collaborative registry of 926 patients enrolled in 10 hospitals from four European countries (Italy, Spain, France and Portugal). Resting Pd/Pa, cFFR and FFR were measured in 1,026 coronary stenoses functionally evaluated using commercially available pressure wires. cFFR was obtained after intracoronary injection of contrast medium, while FFR was measured after administration of adenosine. Resting Pd/Pa and cFFR were significantly higher than FFR (0.93±0.05 vs. 0.87±0.08 vs. 0.84±0.08, ptime and costs.

Assess the agreement between commonly used self-report methods compared with objectively measured physical activity (PA) in defining the prevalence of individuals compliant with PA recommendations. Time spent in moderate and vigorous PA (MVPA) was measured at two time points in 1713 healthy individuals from nine European countries using individually calibrated combined heart rate and movement sensing. Participants also completed the Recent Physical Activity Questionnaire (RPAQ), short form of the International Physical Activity Questionnaire (IPAQ), and short European Prospective Investigation into Cancer and Nutrition Physical Activity Questionnaire (EPIC-PAQ). Individuals were categorized as active (e.g., reporting ≥150 min of MVPA per week) or inactive, based on the information derived from the different measures. Sensitivity and specificity analyses and Kappa statistics were performed to evaluate the ability of the three PA questionnaires to correctly categorize individuals as active or inactive. Prevalence estimates of being sufficiently active varied significantly (P for all PAQ 39.9% [95% CI, 37.5-42.1] and objective measure 48.5% [95% CI, 41.6-50.9]. All self-report methods showed low or moderate sensitivity (IPAQ 20.0%, RPAQ 18.7%, and EPIC-PAQ 69.8%) to correctly classify inactive people and the agreement between objective and self-reported PA was low (ĸ = 0.07 [95% CI, 0.02-0.12], 0.12 [95% CI, 0.06-0.18], and 0.19 [95% CI, 0.13-0.24] for IPAQ, RPAQ, and EPIC-PAQ, respectively). The modest agreement between self-reported and objectively measured PA suggests that population levels of PA derived from self-report should be interpreted cautiously. Implementation of objective measures in large-scale cohort studies and surveillance systems is recommended.

Children's television viewing and objectively measured physical activity: associations with family circumstance

Directory of Open Access Journals (Sweden)

Salmon Jo

2006-10-01

Full Text Available Abstract Background The contribution of family circumstance to physical activity and television viewing has not been widely investigated in pre-adolescents, and available information is inconsistent. This study examines whether television viewing and objectively measured physical activity vary by different indicators of family circumstance. Methods Data from the 2001 Children's Leisure Activity Study and the 2002/3 Health, Eating and Play Study, involving Australian children in Grades Prep (mean age 6y and 5–6 (mean age 11y, were combined. Children wore accelerometers for six consecutive 24 hour periods. Average min/day in low-intensity activity (1.0–1.9 METs and moderate-to-vigorous-intensity activity (≥3 METs were calculated. Parents reported children's television viewing and family circumstance. Linear regression analyses were conducted separately for young girls, young boys, older girls and older boys. Results Complete data were available for 2458 children. Parental education and, to a lesser extent, employment level were inversely associated with television viewing. Children in single-parent families, those whose fathers were not in paid employment, and those without siblings tended to spend more time in low-intensity activity than their peers. Children with siblings spent more time in moderate-to-vigorous-intensity activity; associations were stronger for girls. Maternal education was positively associated with moderate-to-vigorous-intensity activity for younger children. Maternal employment was positively associated with moderate-to-vigorous-intensity activity for older children. Multivariable models did not demonstrate a cumulative explanatory effect. Conclusion Individual measures of family circumstance were differentially associated with television, low-intensity activity and moderate-to-vigorous-intensity activity and associations were often not consistent across age-by-gender groups. Interventions may need to be tailored

Objectivity in psychosocial measurement: what, why, how.

Science.gov (United States)

Fisher, W P

2000-01-01

This article raises and tries to answer questions concerning what objectivity in psychosocial measurement is, why it is important, and how it can be achieved. Following in the tradition of the Socratic art of maiuetics, objectivity is characterized by the separation of meaning from the geometric, metaphoric, or numeric figure carrying it, allowing an ideal and abstract entity to take on a life of its own. Examples of objective entities start from anything teachable and learnable, but for the purposes of measurement, the meter, gram, volt, and liter are paradigmatic because of their generalizability across observers, instruments, laboratories, samples, applications, etc. Objectivity is important because it is only through it that distinct conceptual entities are meaningfully distinguished. Seen from another angle, objectivity is important because it defines the conditions of the possibility of shared meaning and community. Full objectivity in psychosocial measurement can be achieved only by attending to both its methodological and its social aspects. The methodological aspect has recently achieved some notice in psychosocial measurement, especially in the form of Rasch's probabilistic conjoint models. Objectivity's social aspect has only recently been noticed by historians of science, and has not yet been systematically incorporated in any psychosocial science. An approach to achieving full objectivity in psychosocial measurement is adapted from the ASTM Standard Practice for Conducting an Interlaboratory Study to Determine the Precision of a Test Method (ASTM Committee E-11 on Statistical Methods, 1992).

Objectives Childhood obesity prevention and treatment depends, in part, on parents acting as agents of change for their children. Our objective was to measure the associations between parenting self-efficacy, parent depressive symptoms, and preschool child behaviors that support healthy growth. Methods We performed a cross-sectional analysis of baseline data from a randomized controlled trial. Parenting self-efficacy was measured using a 5-item version of the Parenting Sense of Competence (PSOC-5) scale (α= 0.8). Parent depressive symptoms were measured using the Center for Epidemiological Studies-Depression (CESD) scale. Child outcomes included diet (24 h diet recall), physical activity (accelerometry), sleep (parent-report), and media use during meals (parent-report). We performed separate multiple linear regressions for each outcome controlling for other covariates. Results The sample consisted of 601 parent-child pairs. Median child age was 4.3 (IQR 3.6-5.1) years; median child body mass index (BMI) percentile was 79.1% (IQR 66.8-88.5%); 90% of children were Hispanic/Latino, and 6% of children were non-Hispanic Black. Median parent age was 31.5 (IQR 27.6-36.0) years; 22% of parents met criteria for depression. Parenting self-efficacy (median PSOC-5 25; IQR 24-28) was negatively correlated with depressive symptoms (ρ = -0.16; p self-efficacy was associated with duration of child's sleep and fewer meals eaten in front of a TV (p self-efficacy and parental depressive symptoms on child sleep duration (p self-efficacy and depressive symptoms were not significantly associated with child physical activity or child diet. Conclusions In this minority population, higher parenting self-efficacy was associated with longer child sleep and fewer meals in front the TV, but parent depressive symptoms mitigated that protective effect for child sleep duration.

Both individual socio-cultural determinants such as selected parental characteristics (migrant background, low educational level and workload) as well as the regional environment are related to childhood overweight and physical activity (PA). The purpose of the study was to compare the impact of distinct socio-cultural determinants such as the regional environment and selected parental characteristics on adiposity, PA and motor skills in preschool children. Forty preschools (N = 542 children) of two culturally different urban regions (German and French speaking part of Switzerland) participated in the study (Ballabeina Study). Outcome measures included adiposity (BMI and skinfold thickness), objectively measured sedentary activities and PA (accelerometers) and agility performance (obstacle course). Parental characteristics (migrant status, educational level and workload) were assessed by questionnaire. Children from the French speaking areas had higher adiposity, lower levels of total and of more intense PA, were more sedentary and less agile than children from the German speaking regions (percent differences for all outcome parameters except for BMI ≥10%; all p ≤ 0.04). Differences in skinfold thickness, sedentary activities and agility, but not in PA, were also found between children of Swiss and migrant parents, though they were ≤8% (p ≤ 0.02). While paternal workload had no effect, maternal workload and parental education resulted in differences in some PA measures and/or agility performance (percent differences in both: ≤9%, p ≤ 0.008), but not in adiposity or sedentary activities (p = NS). Regional differences in skinfold thickness, PA, sedentary activities and agility performance persisted after adjustment for parental socio-cultural characteristics, parental BMI and, where applicable, children's skinfolds (all p ≤ 0.01). The regional environment, especially the broader social environment, plays a prominent role in determining adiposity, PA and

Evidence-based parenting interventions are important in assisting parents to help their children develop healthy body image and eating patterns. To adequately assess the impact of parenting interventions, valid parent measures are required. The aim of this study was to develop and assess the validity and reliability of two new parent measures, the Parenting Intentions for Body image and Eating patterns in Childhood (Parenting Intentions BEC) and the Knowledge Test for Body image and Eating patterns in Childhood (Knowledge Test BEC). Participants were 27 professionals working in research or clinical treatment of body dissatisfaction or eating disorders, and 75 parents of children aged 2-6 years, who completed the measures via an online questionnaire. Seven scenarios were developed for the Parenting Intentions BEC to describe common experiences about the body and food that parents might need to respond to in front of their child. Parents ranked four behavioural intentions, derived from the current literature on parenting risk factors for body dissatisfaction and unhealthy eating patterns in children. Two subscales were created, one representing positive behavioural intentions, the other negative behavioural intentions. After piloting a larger pool of items, 13 statements were used to construct the Knowledge Test BEC. These were designed to be factual statements about the influence of parent language, media, family meals, healthy eating, and self-esteem on child eating and body image. The validity of both measures was tested by comparing parent and professional scores, and reliability was assessed by comparing parent scores over two testing occasions. Compared with parents, professionals reported significantly higher scores on the Positive Intentions subscale and significantly lower on the Negative Intentions subscale of the Parenting Intentions BEC; confirming the discriminant validity of six out of the seven scenarios. Test-retest reliability was also confirmed as

Full Text Available Abstract Background Identifying leisure time activities performed before and after school that influence time in physical activity (PA and/or time spent sedentary can provide useful information when designing interventions aimed to promote an active lifestyle in young people. The purpose of this study was to examine associations between mode of transportation to school, outdoor play after school, participation in exercise in clubs, and TV viewing with objectively assessed PA and sedentary behaviour in children. Methods A total of 1327 nine- and 15-year-old children from three European countries (Norway, Estonia, Portugal participated as part of the European Youth Heart Study. PA was measured during two weekdays and two weekend days using the MTI accelerometer, and average percent of time in moderate-to-vigorous PA (MVPA and time spent sedentary were derived. Potential correlates were assessed by self-report. Independent associations between self-reported correlates with percent time in MVPA and percent time sedentary were analysed by general linear models, adjusted by age, gender, country, measurement period, monitored days and parental socio-economic status. Results In 9-year-olds, playing outdoors after school was associated with higher percent time in MVPA (P Conclusion Frequency of outdoor play after school is a significant correlate for daily time in MVPA in 9-year-olds, while this correlate is attenuated in favour of participation in sport and exercise in clubs in 15-year-olds. Targeting walking to school or reduced TV viewing time in order to increase time in daily MVPA in children is unlikely to be sufficient. Correlates related to time spent sedentary need further examination.

Full Text Available This study explores the relationship between reported parental emotional neglect when a child, assault type experienced, posttraumatic stress symptoms (PTSS, depression, and alcohol consumption in treatment seekers for comorbid depressive symptoms and alcohol misuse. Participants (n = 220 with concurrent depression and alcohol misuse were recruited from the DAISI (Depression and Alcohol Integrated and Single-focussed Interventions project. Assault type and PTSS were retrospectively assessed by the Posttraumatic Stress Diagnostic Scale. The Measure of Parenting Style is a self-report measure that retrospectively assessed emotional neglect experienced as a child. An exploratory factor analysis using the tetrachoric correlation matrix (applying principal factor extraction with a varimax rotation identified the two assault factors of sexual assault (SA and physical assault (PA. A path analysis revealed that Maternal Emotional Neglect increased the impact of PTSS and depression. Paternal Emotional Neglect increased the impact of PA on PTSS and alcohol dependence symptoms. There appears to be differential effects of assault type and Maternal/Paternal emotional neglect on depression and alcohol misuse, suggesting that parenting roles serve distinct protective functions.

OBJECTIVES: Parents from different cultures differ in how frequently they express emotions. However, the generalizability of the relations between parental expressivity and child adjustment in non-Western cultures has not been extensively studied. The goal of the present study was to investigate prospective relations between parental expressivity within the family (positive, negative dominant, and negative submissive expressivity) and Chinese children's psychological adjustment, above and beyond parenting styles. DESIGN: The study used two waves (3.8 years apart) of longitudinal data from a sample (n= 425) of children in Beijing (mean ages = 7.7 years at T1 and 11.6 years at T2). Parental expressivity and parenting styles were self-reported. To reduce the potential measurement overlap, items that tap parental expression of emotions toward the child were removed from the parenting style measure. Children's adjustment was measured with parents', teachers', and peers' or children's reports. RESULTS: Consistent with findings with European American samples, parental negative dominant expressivity uniquely and positively predicted Chinese children's externalizing problems controlling for prior externalizing problems, parenting styles, and family SES. Neither parental expressivity nor parenting styles uniquely predicted social competence. CONCLUSIONS: Despite previously reported cultural differences in the mean levels of parental expressivity, some of the socialization functions of parental expressivity found in Western countries can be generalized to Chinese families. Although parental expressivity and parenting styles are related constructs, their unique relations to child's adjustment suggest that they should be examined as distinct processes.

Objective Examine stress levels of parents of children with hemifacial microsomia (HFM) and the relationship of parental stress to child characteristics and cognitive coping strategies. Design Prospective cross-sectional study. Participants and Setting Parents with a child (age 3-19 years) with HFM (N = 31) were recruited through the Department of Orthodontics and the Craniofacial Center, Sophia-Erasmus Medical Center, Rotterdam, The Netherlands. Intervention and Outcome Measures The adapted and shortened Dutch version of the parental stress index (NOSI-K) was used to measure parental stress, and the cognitive emotion-regulation questionnaire was used to measure cognitive coping strategies. Pearson correlations and a multiple regression analysis were performed. Results The hierarchical multiple regression analysis showed associations between increased parental stress and learning difficulties and use of acceptance as a coping strategy. This suggests that problems other than the characteristic visual appearance of the child's face in HFM have a greater influence on parental stress. Conclusions Learning difficulties of the child with HFM and parental acceptance affect stress in parents with a child with HFM the most and are important in the search for a targeted tailoring of intervention for parents with high levels of parental stress.

This is a two-study paper that developed a measure to assess parenting practices related to children's physical activity and explored maternal predictors of such parenting practices. Study 1: A self-report measure of parents' activity-related practices (the Parenting Related to Activity Measure) was developed, and a principal component analysis was carried out using data from 233 mothers of 4.5- to 9-year-old children. The results supported a six-factor model and yielded the following subscales: Responsibility/monitoring; Activity regulation; Control of active behaviours; Overweight concern; Rewarding parenting; and Pressure to exercise. Study 2: Mothers (N = 170) completed the Parenting Related to Activity Measure, alongside measures of eating psychopathology and compulsive exercise, to identify predictors of activity-related parenting practices. Mothers' eating psychopathology and exercise beliefs predicted activity parenting practices with their sons and daughters, but different predictors were seen for mothers of daughters versus sons. Mothers' eating and exercise attitudes are important predictors of their activity-related parenting practices, particularly with girls. Identifying early interactions around activity/exercise could be important in preventing the development of problematic beliefs about exercise, which are often a key symptom of eating disorders.

Protactinium-231 ( 231 Pa) occurs in nature as a member of the decay chain of naturally occuring 235 U of the 4n+ 3 radioactive series. The expected protactinium concentration in the Jaduguda ore body (with uranium concentration of 0.03-0.06 %) is around 0.2 parts per billion (ppb) and that in monazite ore (uranium concentration 0.3%) is 0.9 ppb. The process at uranium ore processing plant at Jaduguda was studied. 231 Pa content in samples from the process streams of the plant was determined. The gamma ray spectrometry method was chosen and standardised in our laboratory to detect and measure 231 Pa in parts per billion levels in these samples. A concentrated source of protactinium could not be found among the assessed streams of Jaduguda uranium plant. The Monazite processing plant at IRE, Aluva was then studied. From the known chemistry of protactinium, the possible distribution of the 231 Pa was guessed at. Accordingly, the process streams of IRE process plant were selected to prospect for 231 Pa and determine the fractionation of protactinium. For analysis of 231 Pa, the thorium bearing samples were chemically treated to remove the thorium daughter products, which interfere in gamma spectrometry. This report describes the planning for prospecting, sample selection, the standardisation of the analysis procedure for determination of 231 Pa content, and the analysis results. The 231 Pa content in various streams of Indian Rare Earths plant was found in the range 0.2 -6.5 ppb. Some of the streams did not carry any protactinium. The fractionation of 231 Pa in the various streams of the plant and the selection of source for recovery of protactinium are discussed in detail. (author)

An impressive discrepancy between reported and measured parental height is often observed. The aims of this study were: (a) to assess whether there is a significant difference between the reported and measured parental height; (b) to focus on the reported and, thereafter, measured height of the partner; (c) to analyse its impact on the calculated target height range. A total of 1542 individual parents were enrolled. The parents were subdivided into three groups: normal height (3-97th Centile), short (97%) stature. Overall, compared with men, women were far better in estimating their own height (p Women of normal stature underestimated the short partner and overestimated the tall partner, whereas male partners of normal stature overestimated both their short as well as tall partners. Women of tall stature estimated the heights of their short partners correctly, whereas heights of normal statured men were underestimated. On the other hand, tall men overestimated the heights of their female partners who are of normal and short stature. Furthermore, women of short stature estimated the partners of normal stature adequately, and the heights of their tall partners were overestimated. Interestingly, the short men significantly underestimated the normal, but overestimated tall female partners. Only measured heights should be used to perform accurate evaluations of height, particularly when diagnostic tests or treatment interventions are contemplated. For clinical trails, we suggest that only quality measured parental heights are acceptable, as the errors incurred in estimates may enhance/conceal true treatment effects.

2014-02-01

A dedicated program has been launched on production of innovative radionuclides for PET imaging and for β- and α targeted radiotherapy using proton or α particles at the ARRONAX cyclotron. Since the accelerator is also able to deliver deuteron beams up to 35 MeV, we have reconsidered the possibility of using them to produce medical isotopes. Two isotopes dedicated to targeted therapy have been considered: 226Th, a decay product of 230Pa, and 186Re. The production cross sections of 230Pa and 186Re, as well as those of the contaminants created during the irradiation, have been determined by the stacked-foil technique using deuteron beams. Experimental values have been quantified using a referenced cross section. The measured cross sections have been used to determine expected production yields and compared with the calculated values obtained using the Talys code with default parameters.

Assessing the validity of parenting measures in a sample of chinese adolescents.

Supple, Andrew J; Peterson, Gary W; Bush, Kevin R

2004-09-01

The purpose of this study was to assess the construct validity of adolescent-report parenting behavior measures (primarily derived from the Parental Behavior Measure) in a sample of 480 adolescents from Beijing, China. Results suggest that maternal support, monitoring, and autonomy granting were valid measures when assessing maternal socialization strategies and Chinese adolescent development. Measures of punitiveness and love withdrawal demonstrated limited validity, whereas maternal positive induction demonstrated little validity. The major implications of these results are that measures of "negative" parenting that included physical or psychological manipulations may not have salience for the development of Chinese adolescents. Moreover, researchers and clinicians should question the applicability of instruments and measures designed to assess family process when working with individuals in families from diverse cultural backgrounds.

To improve our understanding of the neighborhood environment - physical activity (PA) relationship, it is of importance to assess associations between neighborhood environmental characteristics and neighborhood-based PA. Participants' (N = 308; 45-65 years) light PA (LPA) and moderate-vigorous PA (MVPA) within a 400, 800, and 1600 m buffer around adults' homes was measured using accelerometers and GPS-devices. Land use data in ArcGIS provided neighborhood characteristics for the same buffers. Multilevel linear regression models, adjusted for socio-demographic variables and attitude towards PA, were used to assess associations of objective neighborhood characteristics with neighborhood-based LPA and MVPA. LPA was positively associated with the proportions of roads (within a 400 m buffer), and negatively associated with the proportions of recreational areas (within an 800 m buffer), and the proportion of green space (within the 800 m and 1600 m buffers). Multiple characteristics of 400 m buffers were positively associated with MVPA, i.e. proportions of green space, blue space, residences, shops and foodservice industry, sports terrain, and public social-cultural facilities. Also, characteristics of larger buffers were positively associated with MVPA, i.e. the proportions of shops and foodservice industry, sports terrain, and blue space (within an 800 m buffer), and the proportion of public social-cultural facilities (within the 800 m and 1600 m buffers). Objective neighborhood characteristics of smaller as well as larger sized buffers were associated with neighborhood-based LPA and MVPA. Green and blue spaces seem to be of particular importance for PA in the smallest buffer, i.e. in the direct surrounding of adults' homes.

To examine objectively determined sedentary behavior and physical activity (PA) during and outside working hours in full-time office workers. A total of 170 participants wore an ActiGraph GT1M accelerometer for 7 days. Time spent sedentary (working hours and nonworking hours) and nonworkdays. Participants accumulated significantly higher levels of sedentary behavior (68% vs 60%) and lower levels of light-intensity activity (28% vs 36%) on workdays in comparison with nonworkdays. Up to 71% of working hours were spent sedentary. Individuals who were most sedentary at work were also more sedentary outside work. Those who are most sedentary at work do not compensate by increasing their PA or reducing their sedentary time outside work. Occupational interventions should address workplace and leisure-time sedentary behavior.

Full Text Available The paper analyzes the psychometric properties of the G1 version of the Parenting Styles and Dimensions Questionnaire, a self-report instrument designed to investigate how adolescents or adults were parented during childhood. The sample included 1451 Italian adolescents in high school. Three studies tested the scale's structure, invariance, and convergent validity. The first found slightly acceptable fit indexes for a 40-item scale measuring three factors (authoritative, authoritarian, and permissive styles; the factors presented good reliability (ρc .62-.96. Multigroup confirmative analyses found factor loadings invariant in the father version, whereas 12 items resulted not invariant in the mother version (second study. Good convergent validity was found with the Parental Bonding Index and the Parental Monitoring Scale (third study. Discussion of results is provided within the parenting styles literature.

Radiation dose to the testes in the antero-posterior (AP) and postero-anterior (PA) projection of the sacroiliac joint (SIJ) was measured with and without a scrotal shield. Entrance surface dose, the dose received by the testicles and the dose area product (DAP) was used. DAP measurements revealed the dose received by the phantom in the PA position is 12.6% lower than the AP (p {<=} 0.009) with no statistically significant reduction in image quality (p {<=} 0.483). The dose received by the testes in the PA projection in SIJ imaging is 93.1% lower than the AP projection when not using protection (p {<=} 0.020) and 94.9% lower with protection (p {<=} 0.019). The dose received by the testicles was not changed by the use of a scrotal shield in the AP position (p {<=} 0.559); but was lowered by its use in the PA (p {<=} 0.058). Use of the PA projection in SIJ imaging significantly lowers, the dose received by the testes compared to the AP projection without significant loss of image quality.

Objective and subjective factors as predictors of post-traumatic stress symptoms in parents of children with cancer--a longitudinal study.

Annika Lindahl Norberg

Full Text Available BACKGROUND: Parents of children with cancer report post-traumatic stress symptoms (PTSS years after the child's successful treatment is completed. The aim of the present study was to analyze a number of objective and subjective childhood cancer-related factors as predictors of parental PTSS. METHODS: Data were collected from 224 parents during and after their child's cancer treatment. Data sources include self-report questionnaires and medical records. RESULTS: In a multivariate hierarchical model death of the child, parent's perception of child psychological distress and total symptom burden predicted higher levels of PTSS. In addition, immigrants and unemployed parents reported higher levels of PTSS. The following factors did not predict PTSS: parent gender, family income, previous trauma, child's prognosis, treatment intensity, non-fatal relapse, and parent's satisfaction with the child's care. CONCLUSIONS: Although medical complications can be temporarily stressful, a parent's perception of the child's distress is a more powerful predictor of parental PTSS. The vulnerability of unemployed parents and immigrants should be acknowledged. In addition, findings highlight that the death of a child is as traumatic as could be expected.

Full Text Available Objective. The objective of this research was to identify retrospectively the alienating behaviors and the parental bonding that occurred in an Italian sample of adults whose had parents separated or divorced and their associations with self-esteem and psychological distress. Methods. Four hundred seventy adults in Chieti, Italy, completed an anonymous and confidential survey regarding their childhood exposure to parental alienating behaviors (using the Baker Strategy Questionnaire, quality of the parent-child relationship (using Parental Bonding Instruments, self-esteem (using Rosenberg Self-Esteem Scale, and global psychological distress (using Global Severity Index of Symptom Checklist-90-Revised. Results. About 80% of the sample reported some exposure to parental alienating behaviors; about 65-70% of the sample has perceived non optimal parenting by mother and by father; individuals who experienced affectionless control (low care and high overprotection reported significantly higher exposure to parental loyalty conflict behaviors. Overall rates of reported exposure to low care, and overprotection and parental loyalty conflict behaviors were statistically significantly associated with self-esteem as well as the measure of current psychological distress. Results revealed that exposure to parental loyalty conflict behaviors and self-esteem were associated with psychological distress over and above the effects of parental bonding and age. Conclusions. The pattern of findings supports the theory that children exposed to dysfunctional parenting, and with low self-esteem are at risk for their long-term psychological functioning. Implications for health policy changes and strengthening social services are discussed.

1969-01-01

A study of Pa-233 excited levels from the alpha decay of Np-237 and from beta decay of Th-233 has been performed. The alpha decay spectrum was measured with a semiconductor spectrometer of 18 keV effective resolution (FWHM). Over 13 new lines were identified. The gamma ray spectra of Np-237 and Th-233 were obtained with a Ge-Li detector low and medium range energy lines, and with Si-Li detector for the low energy region. A continuous purification method of Np-237 from its comparatively short-lived daughter Pa-233 was applied. A high number of new lines were identified in both spectra. The gamma-gamma coincidence spectra were obtained with INa(T 1 ) detectors. (Author) 54 refs

Different opinions of physicians on the importance of measures to prevent acquisition of Pseudomonas aeruginosa from the environment.

Steinkamp, Gratiana; Ullrich, Gerald

2003-12-01

Since chronic infection with mucoid Pseudomonas aeruginosa (PA) is associated with deteriorating lung function, many parents of young children with cystic fibrosis (CF) fear the first PA positive throat swab as a milestone in the progression of the disease. To reduce the risk of PA acquisition from the environment, they perform preventive measures at home or outdoors. In an attempt to evaluate the attitude of CF physicians towards these measures and the respective consulting practice, we mailed a questionnaire to all 65 certified paediatric CF centres in Germany. Physicians from 54 (83%) CF clinics replied. They expressed widely different ideas about the impact of the environment for the acquisition of P. aeruginosa, and recommended a large spectrum of preventive measures. Some physicians proposed only few precautions, which focussed on the prevention of cross-infection between patients, whereas others suggested prevention of any contact with moist or wet places, e.g. use different toothbrushes for mornings and evenings, or do without air-conditioning in the car. CF physicians have different opinions on the risk of PA acquisition from the environment. Doctors who recommend strict precautions could engender a parental fear of a ubiquous threat from invisible bacteria. The resulting extended safety measures might impair the family's quality of life.

Some types of parent number talk count more than others: relations between parents' input and children's cardinal-number knowledge.

Gunderson, Elizabeth A; Levine, Susan C

Before they enter preschool, children vary greatly in their numerical and mathematical knowledge, and this knowledge predicts their achievement throughout elementary school (e.g. Duncan et al., 2007; Ginsburg & Russell, 1981). Therefore, it is critical that we look to the home environment for parental inputs that may lead to these early variations. Recent work has shown that the amount of number talk that parents engage in with their children is robustly related to a critical aspect of mathematical development - cardinal-number knowledge (e.g. knowing that the word 'three' refers to sets of three entities; Levine, Suriyakham, Rowe, Huttenlocher & Gunderson, 2010). The present study characterizes the different types of number talk that parents produce and investigates which types are most predictive of children's later cardinal-number knowledge. We find that parents' number talk involving counting or labeling sets of present, visible objects is related to children's later cardinal-number knowledge, whereas other types of parent number talk are not. In addition, number talk that refers to large sets of present objects (i.e. sets of size 4 to 10 that fall outside children's ability to track individual objects) is more robustly predictive of children's later cardinal-number knowledge than talk about smaller sets. The relation between parents' number talk about large sets of present objects and children's cardinal-number knowledge remains significant even when controlling for factors such as parents' socioeconomic status and other measures of parents' number and non-number talk. © 2011 Blackwell Publishing Ltd.

Inactivity and more sedentary time predominate the daily activity level of many of today's children. In Denmark, certified sport after-school cares have been established in order to increase children's daily physical activity (PA) level. This cross-sectional study aimed to investigate the activity level among participants in certified sport after-school cares vs regular after-school cares. The study was carried out in 2011 in 10 after-school cares (5 sport/5 regular) throughout Denmark, whereof 475 children aged 5-11 years participated. PA level was assessed using Actigraph GT3X and GT3X+ activity monitors worn by the children for at least 8 consecutive days. Anthropometry and cardiorespiratory fitness were measured as well. A multivariate regression analysis was carried out to check for the differences in the PA level across the two care systems. However, there did not appear to be any differences in overall PA or in time-specific day parts (e.g., during after-school care). The activity levels were quite similar across after-school cares and were mutually high during time spent in the care facility. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Full Text Available Abstract Background Studies on parent-child correlations of physical activity have been mixed. Few studies have examined concurrent temporal patterns of physical activity and sedentary behaviors in parents and children using direct measures. The purpose of this study was to examine parent-child activity correlations by gender, day of week, and time of day, using accelerometers - a method for direct assessment of physical activity. Methods Accelerometers were used to assess physical activity and sedentary time in 45 fathers, 45 mothers and their children (23 boys, 22 girls, mean age 9.9 years over the course of 4 days (Thursday - Sunday. Participants were instructed to wear accelerometers for 24 hours per day. Data from accelerometers were aggregated into waking hours on weekdays and weekends (6:00 am to midnight and weekday after-school hours (3:00 - 7:00 pm. Results Across the 4 days, the mean minutes per day of moderate-to-vigorous physical activity (MVPA for fathers was 30.0 (s.d. = 17.3, for mothers was 30.1 (s.d. = 20.1 and for children was 145.47 (s.d. = 51.64. Mothers' and fathers' minutes of MVPA and minutes of sedentary time were positively correlated with child physical activity and sedentary time (all ps Conclusions Greater parental MVPA was associated with increased child MVPA. In addition, having two parents with higher levels of MVPA was associated with greater levels of activity in children. Sedentary time in children was not as strongly correlated with that of their parents. Findings lend support to the notion that to increase childhood activity levels it may be fruitful to improve physical activity among parents.

Childhood unintentional injuries are perceived as a leading public health issue since they are one of the preventable causes of paediatric mortality and morbidity. Whether and how parental factors are related to childhood injury has been researched insufficiently. To investigate parents' attitudes to preventive measures of unintentional childhood injury, and the parental adherence to these measures. Cross-sectional, descriptive study. The data were collected from the parents of children younger than ten years of age admitted to university hospital outpatient clinics for any reason and who agreed to be involved in the study. The first part of the questionnaire included sociodemographic profiles of participating children. Serious injuries were considered to be any injury that requires hospital admission. The second part of the questionnaire was prepared to evaluate parents' adherence to injury prevention rules. A total score calculation about the adherence of the parents to the injury prevention rules was worked out the addition of the scores of each answer given in each age group. Answers for each item given by the parents were scored as wrong (0), sometimes (1) or correct (2). The score for each item was added and the result normalized to 100 points. Only complete questionnaires were used for analysis. A total of 1126 children and parent pairs agreed to participate in the survey. It was found that 13.8% of the participating children had experienced at least one serious injury. Although three-quarters of the parents had received information about injury prevention, the overall injury prevention scores were found to be low. As children's age increased, the total injury prevention scores of parents decreased significantly. Injury prevention scores were shown to increase significantly with high education and maternal occupation. However, scores were shown to decrease significantly with increased child age and family size. Our study shows that parental adherence to the

There is growing interest in the relationship between general parenting and childhood obesity. However, assessing general parenting via surveys can be difficult due to issues with self-report and differences in the underlying constructs being measured. As a result, different aspects of parenting have been associated with obesity risk. We developed a more objective tool to assess general parenting by using observational methods during a mealtime interaction. The General Parenting Observational Scale (GPOS) was based on prior work of Baumrind, Maccoby and Martin, Barber, and Slater and Power. Ten dimensions of parenting were included; 4 were classified in the emotional dimension of parenting (warmth and affection, support and sensitivity, negative affect, detachment), and 6 were classified in the behavioral dimension of parenting (firm discipline and structure, demands for maturity, psychological control, physical control, permissiveness, neglect). Overweight children age 8-12 years old and their parent (n = 44 dyads) entering a weight control program were videotaped eating a family meal. Parents were coded for their general parenting behaviors. The Mealtime Family Interaction Coding System (MICS) and several self-report measures of general parenting were also used to assess the parent-child interaction. Spearman's correlations were used to assess correlation between measures. The emotional dimensions of warmth/affection and support/sensitivity, and the behavioral dimension of firm discipline/structure were robustly captured during the family meals. Warmth/affection and support/sensitivity were significantly correlated with affect management, interpersonal involvement, and communication from the MICS. Firm discipline/structure was inversely correlated with affect management, behavior control, and task accomplishment. Parents who were older, with higher educational status, and lower BMIs were more likely to display warmth/affection and support/sensitivity. Several

The validity of two analogous caregiver/parent report measures of early language development in young children who are learning both English and Spanish is examined. Caregiver/parent report indices of vocabulary production and grammar were obtained for 26 children using the MacArthur Communicative Development Inventory: Words & Sentences (CDI; Fenson et al., 1994) and the Inventario del Desarrollo de Habilidades Comunicativas: Palabras y Enunciados (IDHC; Jackson-Maldonado, Bates, & Thal, 1992). Scores were significantly correlated with analogous laboratory measures in both English and Spanish, including a real-object naming task and spontaneous language use during free-play. The findings offer evidence that the CDI and IDHC provide valid assessments of early language milestones in young English- and Spanish-speaking children. Factors that may influence the validity of these tools for use with this population are also discussed.

Parenthood has been associated with declines in leisure-time exercise and moderate-to-vigorous physical activity (MVPA), but less is known about its impact on sedentary time and light-intensity activity. Although the health benefits of MVPA are well established, a growing body of research has been showing that even after controlling for MVPA levels, a detrimental dose-response association exists between sedentary time and adverse health outcomes and a beneficial dose-response association exists for light-intensity activity. This study examined the impact of parenthood, the number of children in the home, and the age of the youngest child on objectively measured physical activity (i.e., accelerometer derived daily minutes of sedentary, light, and MVPA) among a nationally representative cross-sectional sample of 2234 men and women who participated in the 2009-2011 Canadian Health Measures Survey. After controlling for sociodemographic variables, ANCOVAs indicated that parents engaged in more light activity but less MVPA than non-parents and women whose youngest child was aged 12-15 years were more sedentary than women without children. Among both men and women, having a child activity and lowest MVPA. Modest differences emerged between the physical activity level of parents and non-parents for both genders and across intensity levels. In general, parenthood was associated with less MVPA and more light-intensity activity, and more differences emerged among women compared to men. More research is needed before conclusions can be drawn regarding the health consequences of these differences.

Parental Expressivity and Parenting Styles in Chinese Families: Prospective and Unique Relations to Children’s Psychological Adjustment

Chen, Stephen H.; Zhou, Qing; Eisenberg, Nancy; Valiente, Carlos; Wang, Yun

2012-01-01

SYNOPSIS Objectives Parents from different cultures differ in how frequently they express emotions. However, the generalizability of the relations between parental expressivity and child adjustment in non-Western cultures has not been extensively studied. The goal of the present study was to investigate prospective relations between parental expressivity within the family (positive, negative dominant, and negative submissive expressivity) and Chinese children’s psychological adjustment, above and beyond parenting styles. Design The study used two waves (3.8 years apart) of longitudinal data from a sample (n= 425) of children in Beijing (mean ages = 7.7 years at T1 and 11.6 years at T2). Parental expressivity and parenting styles were self-reported. To reduce the potential measurement overlap, items that tap parental expression of emotions toward the child were removed from the parenting style measure. Children’s adjustment was measured with parents’, teachers’, and peers’ or children’s reports. Results Consistent with findings with European American samples, parental negative dominant expressivity uniquely and positively predicted Chinese children’s externalizing problems controlling for prior externalizing problems, parenting styles, and family SES. Neither parental expressivity nor parenting styles uniquely predicted social competence. Conclusions Despite previously reported cultural differences in the mean levels of parental expressivity, some of the socialization functions of parental expressivity found in Western countries can be generalized to Chinese families. Although parental expressivity and parenting styles are related constructs, their unique relations to child’s adjustment suggest that they should be examined as distinct processes. PMID:23226715

Radiation dose to the testes in the antero-posterior (AP) and postero-anterior (PA) projection of the sacroiliac joint (SIJ) was measured with and without a scrotal shield. Entrance surface dose, the dose received by the testicles and the dose area product (DAP) was used. DAP measurements revealed the dose received by the phantom in the PA position is 12.6% lower than the AP (p ≤ 0.009) with no statistically significant reduction in image quality (p ≤ 0.483). The dose received by the testes in the PA projection in SIJ imaging is 93.1% lower than the AP projection when not using protection (p ≤ 0.020) and 94.9% lower with protection (p ≤ 0.019). The dose received by the testicles was not changed by the use of a scrotal shield in the AP position (p ≤ 0.559); but was lowered by its use in the PA (p ≤ 0.058). Use of the PA projection in SIJ imaging significantly lowers, the dose received by the testes compared to the AP projection without significant loss of image quality.

The hotdog fold is one of the basic protein folds widely present in bacteria, archaea and eukaryotes. Many of these proteins exhibit thioesterase activity against fatty acyl-CoAs and play important roles in lipid metabolism, cellular signalling and degradation of xenobiotics. The genome of the opportunistic pathogen Pseudomonas aeruginosa contains over 20 genes encoding predicted hotdog-fold proteins, none of which have been experimentally characterized. We have found that two P. aeruginosa hotdog proteins display high thioesterase activity against 3-hydroxy-3-methylglutaryl-CoA and glutaryl-CoA (PA5202), and octanoyl-CoA (PA2801). Crystal structures of these proteins were solved (at 1.70 and 1.75 Å for PA5202 and PA2801 respectively) and revealed a hotdog fold with a potential catalytic carboxylate residue located on the long α-helix (Asp(57) in PA5202 and Glu(35) in PA2801). Alanine residue replacement mutagenesis of PA5202 identified four residues (Asn(42), Arg(43), Asp(57) and Thr(76)) that are critical for its activity and are located in the active site. A P. aeruginosa PA5202 deletion strain showed an increased secretion of the antimicrobial pigment pyocyanine and an increased expression of genes involved in pyocyanin biosynthesis, suggesting a functional link between PA5202 activity and pyocyanin production. Thus the P. aeruginosa hotdog thioesterases PA5202 and PA2801 have similar structures, but exhibit different substrate preferences and functions.

Parker, Sarah J; Strath, Scott J; Swartz, Ann M

2008-10-01

This study examined the relationship between physical activity (PA) and mental health among older adults as measured by objective and subjective PA-assessment instruments. Pedometers (PED), accelerometers (ACC), and the Physical Activity Scale for the Elderly (PASE) were administered to measure 1 week of PA among 84 adults age 55-87 (mean = 71) years. General mental health was measured using the Positive and Negative Affect Scale (PANAS) and the Satisfaction With Life Scale (SWL). Linear regressions revealed that PA estimated by PED significantly predicted 18.1%, 8.3%, and 12.3% of variance in SWL and positive and negative affect, respectively, whereas PA estimated by the PASE did not predict any mental health variables. Results from ACC data were mixed. Hotelling-William tests between correlation coefficients revealed that the relationship between PED and SWL was significantly stronger than the relationship between PASE and SWL. Relationships between PA and mental health might depend on the PA measure used.

Identifying correlates of sedentary behaviour across all levels of the ecological model and understanding their interrelations is a promising method to plan effective interventions. The present study examined whether the objectively assessed and the perceived neighbourhood are associated with children’s sedentary behaviour time (SBT). A comprehensive set of factors at different levels of influence across the ecological model were taken into account and analysed for mediating and modifying effects. Analyses were based on 1306 children and adolescents (6⁻16 years) participating in the population-based SOPHYA-study. Accelerometers were used to assess SBT, the perceived environment was examined by a validated parental questionnaire, and objective environmental data were allocated using GIS (ArcMap 10.2, Esri, Redlands, CA, USA) for each family’s residential address. A high perceived safety was associated with less SBT. Boys, those whose residential neighbourhood was characterized by dead ends in urban areas, a low main street density in the neighbourhood of children and greenness were less likely to exhibit SBT. The association of the objective environment with the respective parental perceptions was low and no significant mediating effect was found for the perceived environment. We conclude for land-use planning to reduce sedentary behaviour objective environments should be complemented with efforts to increase parental sense of security.

Public acceptance (PA) of nuclear energy in Japan

Ishii, Makoto

1994-01-01

Japan's nuclear development is carried out in the spirit of the Atomic Energy Basic Law that it adopted in 1955. The only nation in the world devastated by nuclear weapons, Japan strongly hopes for the abolishment of nuclear weapons and promotes the peaceful use of nuclear energy. Since Japan is in poor in natural resources nuclear power has now become a major foundation of our society and economy. As far as the Japanese people's awareness of nuclear power generation is concerned, 60% recognize it as necessary although 70% are concerned about its safety. The public acceptance (PA) of nuclear energy is facing a critical juncture at thus point due to such imminent issues as the use of plutonium and the disposal of high-level wastes. The entire Japanese government is currently striving to promote PA measures targeting various population groups. This paper reports on the peaceful use of nuclear energy and Japan's stance on this issue; people's awareness; and the current state of nuclear energy PA measures. 1 fig

Multi-modal distribution crossover method based on two crossing segments bounded by selected parents applied to multi-objective design optimization

Energy Technology Data Exchange (ETDEWEB)

Ariyarit, Atthaphon; Kanazaki, Masahiro [Tokyo Metropolitan University, Tokyo (Japan)

2015-04-15

This paper discusses airfoil design optimization using a genetic algorithm (GA) with multi-modal distribution crossover (MMDX). The proposed crossover method creates four segments from four parents, of which two segments are bounded by selected parents and two segments are bounded by one parent and another segment. After these segments are defined, four offsprings are generated. This study applied the proposed optimization to a real-world, multi-objective airfoil design problem using class-shape function transformation parameterization, which is an airfoil representation that uses polynomial function, to investigate the effectiveness of this algorithm. The results are compared with the results of the blend crossover (BLX) and unimodal normal distribution crossover (UNDX) algorithms. The objective of these airfoil design problems is to successfully find the optimal design. The outcome of using this algorithm is superior to that of the BLX and UNDX crossover methods because the proposed method can maintain higher diversity than the BLX and UNDX methods. This advantage is desirable for real-world problems.

The potential for hypothermia as a neuroprotectant during stroke has led to its increase in clinical use. At the same time, combination pharmaceutical therapies for ischemic stroke using recombinant tissue plasminogen activator (rt-PA), and GP IIb-IIIa inhibitors, such as Eptifibatide (Epf ), are under study. However, there is little data on how the reactions triggered by these agents are impacted by temperature. Here, clot lysis during exposure to the combination of rt-PA and Epf is measured in an in vitro human clot model at hypothermic temperatures. The hypothesis is that lytic efficacy of rt-PA and Epf decreases with decreasing temperature. Whole blood clots from 31 volunteers were exposed to rt-PA (0.5 μg/mL) and Epf (0.63 μg/mL) in human fresh-frozen plasma (rt-PA+Epf ), rt-PA alone in plasma (rt-PA Alone), or to plasma alone (Control), at temperatures from 30°C to 37°C, for 30 minutes. Clot lysis was measured using a microscopic imaging technique; the mean fractional clot loss (FCL) at 30 minutes was used to determine lytic efficacy. Temperature had a significant impact on FCL in clots exposed to rt-PA+Epf, with the FCL being lower at 30°C to 36°C than at 37°C. The FCL remained significantly higher for rt-PA+Epf–treated clots than Controls regardless of temperature, with the exception of measurements made at 30°C when no significant differences in the FCL were observed between groups. The use of hypothermia as a neuroprotectant may negatively impact the therapeutic benefit of thrombolytic agents.

Distributed Measurement Data Gathering about Moving Objects

Directory of Open Access Journals (Sweden)

Ivan Kholod

2017-01-01

Full Text Available This paper describes approaches to gathering measurement data about moving objects in networks with low bandwidth. The first approach uses Fog computing conception and suggests moving assessing the quality of the measurement data into measuring points. The second approach uses prediction of telemetry quality by mining models. In addition, the paper presents implementation of these approaches based on actor model. As a result, it became possible not only to load balancing among edge and cloud nodes, but also to significantly reduce the network traffic, which in turn brings the possibility of decreasing the requirements for communication channels bandwidth and of using wireless networks for gathering measurement data about moving objects.

To test the validity and reliability of Brazilian Portuguese version of the Parental-Caregiver Perceptions Questionnaire (P-CPQ) (Aim 1) and to assess the agreement between parents and children concerning the child's oral health-related quality of life (OHRQoL) (Aim 2). The P-CPQ and the Brazilian Portuguese versions of the Child Perceptions Questionnaires (CPQ8-10 and CPQ11-14 ) were used. Objective 1 addressed in the study that involved 210 (validity and internal reliability) and 20 (test-retest reliability) parents and Objective 2 in the study that involved 210 pairs of parents and children. Construct validity was calculated using the Spearman's correlation and the Mann-Whitney/Kruskal-Wallis tests. Reliability was determined using Cronbach's alpha and intraclass correlation coefficient (ICC). Agreement between overall and subscale scores derived from the P-CPQ and CPQ was assessed in comparison and correlation analyses. The P-CPQ discriminated among the categories of malocclusion and dmft. The P-CPQ showed good construct validity, good internal consistency reliability, and excellent test-retest reliability. There was systematic under- and overreporting in parents' assessments for younger and older children, respectively. However, the magnitude of the directional differences was just small. At individual level, agreement between parents and children was excellent. However, it ranged from excellent to moderate or substantial in subscales for CPQ8-10 and CPQ11-14 groups, respectively. The Portuguese version of P-CPQ is valid and reliable. Some parents have limited knowledge about child OHRQoL. Given that parental and child reports measure different realities concerning the child's OHRQoL, information provided by parents can complement the child's evaluation. © 2015 American Association of Public Health Dentistry.

The results of a key comparison of ultra-high vacuum standards at two national metrology institutes (NMIJ/AIST and KRISS) are reported. This bilateral comparison was carried out from May 2010 to October 2010 within the framework of the Asia-Pacific Metrology Programme (APMP) to determine their degrees of equivalence at pressures in the range from 3 × 10-6 Pa to 9 × 10-4 Pa. The pilot institute was NMIJ/AIST. Two spinning rotor gauges and two hot cathode ionization gauges were used as the transfer standards. NMIJ/AIST used two calibration systems: the dynamic expansion system (NMIJ-DES) and two-stage flow-dividing system (NMIJ-TFS). KRISS used the dynamic expansion system. The transfer standards were sufficiently stable to meet the requirements of the comparison compared with those of previous international comparisons owing to some improvements of the protocol and the transfer standards. The ultra-high vacuum standards of NMIJ/AIST and KRISS were found to be equivalent within their claimed uncertainties in the range from 3 × 10-6 Pa to 9 × 10-5 Pa. The NMIJ-DES results, which have smaller uncertainty than NMIJ-TFS, were transferred to the corresponding CCM key comparison, CCM.P-K3, in the range from 3 × 10-6 Pa to 9 × 10-5 Pa and it is shown that the NMIJ values were equivalent to the CCM key comparison reference value within the claimed uncertainties.

Background Although obesity rates are high among Latino children, relatively few studies of parental feeding practices have examined Latino families as a separate group. Culturally-based approaches to measurement development can begin to identify parental feeding practices in specific cultural groups. This study used qualitative and quantitative methods to develop and test the Parental Feeding Practices (PFP) Questionnaire for use with Mexican American parents. Items reflected both parent’s use of control over child eating and child-centered feeding practices. Methods In the qualitative phase of the research, 35 Latino parents participated in focus groups. Items for the PFP were developed from focus group discussions, as well as adapted from existing parent feeding practice measures. Cognitive interviews were conducted with 37 adults to evaluate items. In the quantitative phase, mothers and fathers of 174 Mexican American children ages 8–10 completed the PFP and provided demographic information. Anthropometric measures were obtained on family members. Results Confirmatory factor analyses identified four parental feeding practice dimensions: positive involvement in child eating, pressure to eat, use of food to control behavior, and restriction of amount of food. Factorial invariance modeling suggested equivalent factor meaning and item response scaling across mothers and fathers. Mothers and fathers differed somewhat in their use of feeding practices. All four feeding practices were related to child body mass index (BMI) percentiles, for one or both parents. Mothers reporting more positive involvement had children with lower BMI percentiles. Parents using more pressure to eat had children with lower BMI percentiles, while parents using more restriction had children with higher BMI percentiles. Fathers using food to control behavior had children with lower BMI percentiles. Conclusions Results indicate good initial validity and reliability for the PFP. It can be

Parents with advanced cancer are faced with difficult decision-making about communication about their illness with their children. The objectives of this study were to describe how parents communicated with their children about advanced cancer and to explore associations between communication and parental depression and anxiety. This was a cross-sectional, mixed-methods study of 42 patients with stage IV solid tumor malignancies who had at least one child less than 18 years of age. Participants completed a semi-structured interview and the Hospital Anxiety and Depression Scale (HADS). We used multiple linear regression to evaluate the association between extent of communication and HADS Anxiety and Depression scores. Interview data were analyzed using standard qualitative content and thematic techniques and triangulated with survey data. Higher HADS Anxiety scores, but not HADS Depression scores, were cross-sectionally associated with greater extent of parental communication (p = 0.003), even when controlling for performance status and children's ages. In qualitative analyses, parents who acknowledged the terminal nature of their illness or experienced higher symptom burden were more likely to report that they also communicated more extensively with children. A third of parents (n = 14, 33%) described difficulty with illness-related communication with their children. In this pilot study, parents with advanced cancer who reported more illness-related communication with their children also reported more symptoms of general anxiety. Future interventions should address psychological distress relevant to parenting and further assess how parental communication may be linked to parental mood symptoms.

2011-06-01

Full Text Available Abstract Background Accelerometers are considered to be the most promising tool for measuring physical activity (PA in free-living young children. So far, no studies have examined the feasibility and validity of accelerometer measurements in children under 3 years of age. Therefore, the purpose of the present study was to examine the feasibility and validity of accelerometer measurements in toddlers (1- to 3-year olds. Methods Forty-seven toddlers (25 boys; 20 ± 4 months wore a GT1M ActiGraph accelerometer for 6 consecutive days and parental perceptions of the acceptability of wearing the monitor were assessed to examine feasibility. To investigate the validity of the ActiGraph and the predictive validity of three ActiGraph cut points, accelerometer measurements of 31 toddlers (17 boys; 20 ± 4 months during free play at child care were compared to directly observed PA, using the Observational System for Recording Physical Activity in Children-Preschool (OSRAC-P. Validity was assessed using Pearson and Spearman correlations and predictive validity using area under the Receiver Operating Characteristic curve (ROC-AUC. Results The feasibility examination indicated that accelerometer measurements of 30 toddlers (63.8% could be included with a mean registration time of 564 ± 62 min during weekdays and 595 ± 83 min during weekend days. According to the parental reports, 83% perceived wearing the accelerometer as 'not unpleasant and not pleasant' and none as 'unpleasant'. The validity evaluation showed that mean ActiGraph activity counts were significantly and positively associated with mean OSRAC-P activity intensity (r = 0.66; p Conclusions The present findings suggest that ActiGraph accelerometer measurements are feasible and valid for quantifying PA in toddlers. However, further research is needed to accurately identify PA intensities in toddlers using accelerometry.

The Parental Attitudes, Beliefs, and Understanding of Anxiety (PABUA) was developed to assess parental beliefs about their child’s anxiety, parents’ perceived ability to cope with their child’s anxiety and to help their child manage anxious symptoms, and to evaluate parents’ understanding of various parenting strategies in response to their child’s anxiety. The study evaluated the PABUA in mother-child dyads (N = 192) seeking treatment for youth anxiety. Exploratory factor analysis yielded a three-factor solution and identified PABUA scales of Overprotection, Distress, and Approach (with Cronbach’s alpha ranging from .67 to .83). Convergent and divergent validity of PABUA scales was supported by the pattern of associations with measures of experiential avoidance, beliefs related to children’s anxiety, empathy, trait anxiety, and depressive symptoms; parent-reported family functioning; parent- and youth-reported anxiety severity; and parent-reported functional impairment (n = 83). Results provide preliminary support for the PABUA as a measure of parental attitudes and beliefs about anxiety, and future studies that investigate this measure with large and diverse samples are encouraged.

Full Text Available The Perceived Parent Success Standards Scale (PPSSS, adapted from the Perception of Success Questionnaire constructed by Roberts et al. (1998 to measure athletes’ achievement goal orientation, provides a measure of athletes’ perceptions of mastery- and ego-oriented parental success criteria, a central component of parental motivational climate. This study focused on 543 young athletes (ages 9–16 on 82 teams in recreational basketball leagues. The PPSSS exhibited strong factorial validity, construct validity, and orthogonality between ego and mastery factors that allow for different combinations of these factors to be tested. We also compared the impact of the motivational climates created by coaches and success standards conveyed by parents on postseason athlete outcome measures of anxiety, self-esteem, and achievement goal orientation. Correlational and multilevel regression analyses revealed that both coach and parent variables were significantly related to the athlete variables. However, mediational analyses indicated that parental success standards mediated relations between coach-initiated climate and all of the outcome variables, reflecting the power of parental socialization processes. We discuss potential reasons for the greater parental influence shown in this and a previous study, and we suggest directions for further research as well as possible interventions that can help both coaches and parents create a more positive athletic environment for young athletes.

Rationale Parenting is an often-studied correlate of children's physical activity, however there is little research examining the associations between parenting styles, practices and the physical activity of younger children. Objective This study aimed to investigate whether physical activity-based parenting practices mediate the association between parenting styles and 5–6 year-old children's objectively-assessed physical activity. Methods 770 parents self-reported parenting style (nurturance and control) and physical activity-based parenting practices (logistic and modeling support). Their 5–6 year old child wore an accelerometer for five days to measure moderate-to-vigorous physical activity (MVPA). Linear regression was used to examine direct and indirect (mediation) associations. Data were collected in the United Kingdom in 2012/13 and analyzed in 2014. Results Parent nurturance was positively associated with provision of modeling (adjusted unstandardized coefficient, β = 0.11; 95% CI = 0.02, 0.21) and logistic support (β = 0.14; 0.07, 0.21). Modeling support was associated with greater child MVPA (β = 2.41; 0.23, 4.60) and a small indirect path from parent nurturance to child's MVPA was identified (β = 0.27; 0.04, 0.70). Conclusions Physical activity-based parenting practices are more strongly associated with 5–6 year old children's MVPA than parenting styles. Further research examining conceptual models of parenting is needed to understand in more depth the possible antecedents to adaptive parenting practices beyond parenting styles. PMID:26647364

BACKGROUND Health Literacy is the ability to obtain, process, and understand health information to make knowledgeable health decisions. PURPOSE To determine baseline health literacy of NICU parents at a tertiary care hospital during periods of crucial information exchange. METHODS Health Literacy of English speaking NICU parents was assessed using the Newest vital Sign (NVS) on admission (n=121) and discharge (n=59). A quasi-control group of well newborn (WBN) parents (n=24) and prenatal obstetric clinic (PRE) parents (n=18) were included. A single, Likert-style question measured nurse’s assessment of parental comprehension with discharge teaching. Suspected limited health literacy (SLHL) was defined as NVS score of ≤3. FINDINGS / RESULTS Forty-three percent of parents on NICU admission and 32% at NICU discharge had SLHL (pNICU parents and 25% of WBN parents with SLHL at time of admission/infant birth had a college education. Nurse subjective measurement of parental comprehension of discharge instructions was not correlated to the objective measurement of health literacy (p=0.26). IMPLICATIONS FOR PRACTICE SLHL is common during peak time periods of complex health discussion in the NICU, WBN, and PRE settings. NICU providers may not accurately gauge parent’s literacy status. IMPLICATIONS FOR RESEARCH Methods for improving health communication are needed. Studies should evaluate SLHL in a larger NICU population and across different languages and cultures. PMID:27391562

In this paper I discuss several theoretical and practical aspects related to measuring and correcting the chromatic and spherical aberrations of a cathode objective lens as used in Low Energy Electron Microscopy (LEEM) and Photo Electron Emission Microscopy (PEEM) experiments. Special attention is paid to the various components of the cathode objective lens as they contribute to chromatic and spherical aberrations, and affect practical methods for aberration correction. This analysis has enabled us to correct a LEEM instrument for the spherical and chromatic aberrations of the objective lens. -- Research highlights: → Presents a comprehensive theory of the relation between chromatic aberration and lens current in a cathode objective lens. → Presents practical methods for measuring both spherical and chromatic aberrations of a cathode objective lens. → Presents measurements of these aberrations in good agreement with theory. → Presents practical methods for measuring and correcting these aberrations with an electron mirror.

Abstract Physical activity (PA) in childhood is related to a multitude of short- and long-term health consequences. School recess can contribute with up to 40% of the recommended 60 min of daily moderate-to-vigorous physical activity (MVPA). This paper aims to investigate how schoolchildren use...... positioning system (GPS) and the level of activity was measured using accelerometers. Total time spent and proportions of time spent sedentary and in MVPA were calculated per area type. Significant differences in PA levels were found. Grass and playground areas had the highest proportion of time in MVPA...... and solid surface areas had the highest proportion of time spent sedentary. Boys and children spent a higher proportion of time in MVPA. Girls accumulated more sedentary time in all area types compared to boys. This finding emphasizes the importance of investigating various settings and features...

The Cementitious Barriers Partnership (CBP) is a collaborative program sponsored by the US DOE Office of Waste Processing. The objective of the CBP is to develop a set of computational tools to improve understanding and prediction of the long-term structural, hydraulic, and chemical performance of cementitious barriers and waste forms used in nuclear applications. CBP tools are expected to better characterize and reduce the uncertainties of current methodologies for assessing cementitious barrier performance and increase the consistency and transparency of the assessment process, as the five-year program progresses. In September 2009, entering its second year of funded effort, the CBP sought opportunities to provide near-term tangible support to DOE Performance Assessments (PAs). The Savannah River Saltstone Disposal Facility (SDF) was selected for the initial PA support effort because (1) cementitious waste forms and barriers play a prominent role in the performance of the facility, (2) certain important long-term behaviors of cementitious materials composing the facility are uncertain, (3) review of the SDF PA by external stakeholders is ongoing, and (4) the DOE contractor responsible for the SDF PA is open to receiving technical assistance from the CBP. A review of the current (SRR Closure and Waste Disposal Authority 2009) and prior Saltstone PAs (e.g., Cook et al. 2005) suggested five potential opportunities for improving predictions. The candidate topics considered were (1) concrete degradation from external sulfate attack, (2) impact of atmospheric exposure to concrete and grout before closure, such as accelerated slag and Tc-99 oxidation, (3) mechanistic prediction of geochemical conditions, (4) concrete degradation from rebar corrosion due to carbonation, and (5) early age cracking from drying and/or thermal shrinkage. The candidate topics were down-selected considering the feasibility of addressing each issue within approximately six months, and

Parents' attitudes about their children's schools matter. Their views can shape their children's attitudes about school, affect their levels of family-school engagement, and influence their residential and school enrollment decisions. In this article, we describe the development of a survey scale to assess parent perceptions of the climate of their child's school. Our comprehensive scale development process incorporated feedback from academics and potential respondents from the outset of the design process to enhance scale quality. We conducted 3 studies with national samples of parents (n = 385; n = 253; n = 266) to gather evidence of scale score reliability and valid score inferences based on convergent and discriminant validity. Through confirmatory factor analysis, we identified a theoretically grounded factor structure that fit the data well but found no evidence that parental response patterns distinguish between academic and social elements of school climate. Furthermore, we found that parents of younger children, on average, had a more positive perception of the school's climate than did parents of older children. We conclude by discussing how researchers and Pre-K-12 schools and districts can use the scale to aid school improvement efforts. 2014 APA

The study aimed to investigate if psychosocial factors moderate the association between objective walkability and different domains of children's physical activity (PA). A second aim of the study was to investigate the direct associations between psychosocial factors and children's PA. Based on previous literature, it was hypothesized that walkability would be more strongly related to PA among children with negative psychosocial profiles. Data were collected between December 2011 and May 2013 as part of the Belgian Environmental Physical Activity Study in children (BEPAS-child). In total, data from 494 children and one of their parents were included in the study. Children wore an accelerometer for 7 consecutive days and together with one of their parents, they completed the Flemish Physical Activity Questionnaire. Parents filled out a questionnaire concerning their child's psychosocial factors toward PA (i.e. parental attitude toward their child's PA, parental social norm toward their child's PA, parental support, friend support, children's self-efficacy, and perceived benefits and barriers toward sports and PA). Neighborhood walkability was calculated using geographical information systems (GIS). Multilevel cross-classified analyses were conducted. Of the 42 investigated interactions between neighborhood walkability and psychosocial factors in relation to PA among children, only 7 significant interactions were found of which 3 were only significant among children from low-income neighborhoods. Parental support and self-efficacy were positive correlates of children's PA in high- and low-income neighborhoods independent of the level of walkability, but effect sizes were small. The hypothesis that walkability would be more strongly related to PA among children with negative psychosocial profiles could not be confirmed and in general, psychosocial factors and objective walkability did not interact in relation to children's PA.

It is now well established that the presence of an opaque classical object can be unambiguously determined by an open-quotes interaction-freeclose quotes measurement (IFM), where the object and the probe never directly interact. For quantum objects, we examine open-quotes interaction-freeclose quotes measurement (the object wavefunction is unchanged) and open-quotes interaction-freeclose quotes preparation (the object wavefunction is changed without physical interaction) and find that in general, neither is possible. We propose using high efficiency IFM close-quote s as a quantum information bus to connect disjoint quantum systems. copyright 1999 American Institute of Physics

PA-MSHA, a genetically engineered Pseudomonas aeruginosa (PA) strain, is currently under investigation as a new anti-cancer drug. It can induce cell cycle arrest and apoptosis in different human cancer cells, including hormone receptor negative breast cancer cells. However, the underlying mechanism of tumor lethality mediated by PA-MSHA remains to be fully investigated. The effect of PA-MSHA on human hormone receptor negative breast cancer cells was analyzed by morphological measurement, western blot, cell proliferation assay and mouse xenograft model. PA-MSHA was found to induce endoplasmic reticulum (ER) stress in breast cancer cell lines through the IRE1 signaling pathway. Inhibiting autophagy potentiated the cytotoxic effect of PA-MSHA while treating breast cancer cell lines. In mouse xenograft model, PA-MSHA produced more pronounced tumor suppression in mice inoculated with IRE1 gene knockdown. MDA-MB-231HM cells. These findings demonstrated inhibiting autophagy together with PA-MSHA might be a promising therapeutic strategy in treating hormone receptor negative breast cancer cells

Full Text Available Exposure to neighborhood danger during childhood has negative effects that permeate multiple dimensions of childhood. The current study examined whether mothers’, fathers’, and children’s perceptions of neighborhood danger are related to child aggression, whether parental monitoring moderates this relation, and whether harsh parenting mediates this relation. Interviews were conducted with a sample of 1293 children (age M = 10.68, SD = 0.66; 51% girls and their mothers (n = 1282 and fathers (n = 1075 in nine countries (China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States. Perceptions of greater neighborhood danger were associated with more child aggression in all nine countries according to mothers’ and fathers’ reports and in five of the nine countries according to children’s reports. Parental monitoring did not moderate the relation between perception of neighborhood danger and child aggression. The mediating role of harsh parenting was inconsistent across countries and reporters. Implications for further research are discussed, and include examination of more specific aspects of parental monitoring as well as more objective measures of neighborhood danger.

The comprehensive in vitro proarrhythmia assay (CiPA) is a nonclinical, mechanism-based paradigm for assessing drug proarrhythmic liability. The first CiPA assay determines effects on cloned human cardiac ion channels. The second investigates whether the latter study-generated metrics engender proarrhythmic markers on a computationally reconstructed human ventricular action potential. The third evaluates conclusions from, and searches possibly missed effects by in silico analysis, in human stem cell-derived cardiomyocytes (hSC-CMs). CiPA ad hoc Expert-Working Groups have proposed patch clamp protocols for seven cardiac ion channels, a modified O'Hara-Rudy model for in silico analysis, detailed procedures for field (MEA) and action potential (VSD) measurements in hSC-CMs, and 29 reference drugs for CiPA assay testing and validation. CiPA adoption as drug development tool for identifying electrophysiological mechanisms conferring proarrhythmic liability to candidate drugs is a complex, multi-functional task requiring significant time, reflection, and efforts to be fully achieved.

Preventive efforts targeting childhood anxiety and depression symptoms have the potential to alter the developmental trajectory of depression and anxiety disorders across the lifespan. Substantial previous research suggests that modifiable parenting factors such as parental aversiveness and over-involvement are associated with childhood anxiety, depressive and internalising symptoms, indicating that parents can play a critical role in prevention. The Parenting Resilient Kids study is a new evidence-based online parenting program designed to prevent anxiety and depression problems in primary school-aged children by reducing family-based risk factors and enhancing protective factors through increased positive interactions between parent and child. The current study is a parallel group superiority randomised controlled trial with parent-child dyads randomised to the intervention or active-control group in a 1:1 ratio. The intervention group will receive the Parenting Resilient Kids program consisting of a feedback report on parenting behaviours and up to 12 interactive online modules personalised based on responses to the parent survey. The active-control group will receive a standardised package of online educational materials about child development and wellbeing. The trial website is programmed to run a stratified random allocation sequence (based on parent gender) to determine group membership. We aim to recruit 340 parent-child dyads (170 dyads per group). We hypothesise that the intervention group will show greater improvement in parenting risk and protective factors from baseline to 3-month follow-up (primary outcome), which will in turn mediate changes in child depressive and anxiety symptoms from baseline to 12 and 24 months (co-primary outcomes). We also hypothesise that the intervention group will show greater benefits from baseline to 3-, 12- and 24-month follow-up, with regard to: child depressive and anxiety symptoms (co-primary outcomes); and child and

Removal of 230Th and 231Pa at ocean margins

Uranium, thorium and protactinium isotopes were measured in particulate matter collected by sediment traps deployed in the Panama Basin and by in-situ filtration of large volumes of seawater in the Panama and Guatemala Basins. Concentrations of dissolved Th and Pa isotopes were determined by extraction onto MnO 2 adsorbers placed in line behind the filters in the in-situ pumping systems. Concentrations of dissolved 230 Th and 231 Pa in the Panama and Guatemala Basins are lower than in the open ocean, whereas dissolved 230 Th/ 231 Pa ratios are equal to, or slightly greater than, ratios in the open ocean. Particulate 230 Th/ 231 Pa ratios in the sediment trap samples ranged from 4 to 8, in contrast to ratios of 30 or more at the open ocean sites previously studied. Particles collected by filtration in the Panama Basin and nearest to the continental margin in the Guatemala Basin contained 230 Th/ 231 Pa ratios similar to the ratios in the sediment trap samples. The ratios increased with distance away from the continent. Suspended particles near the margin show no preference for adsorption of Th or Pa and therefore must be chemically different from particles in the open ocean, which show a strong preference for adsorption of Th. Ocean margins, as typified by the Panama and Guatemala Basins, are preferential sinks for 231 Pa relative to 230 Th. Furthermore, the margins are sinks for 230 Th and, to a greater extent, 231 Pa transported by horizontal mixing from the open ocean. (orig.)

2013-03-01

In most studies, the parental version of the CFSS-DS is used; however, no information is available concerning the extent to which parents are able to report dental fear on behalf of their children. This study aims to assess whether parents are accurate reporters of their child's dental fear. The CFSS-DS was filled out by 326 children in a classroom setting and by 167 parents (mostly mothers) at home on behalf of their child. Intraclass correlation coefficients were used as a measure of agreement between both CFSS-DS versions, and reasons for nonagreement were assessed. Mean CFSS-DS for children was 21.15 (SD = 6.4) and for parents 23.26 (SD = 6.7). The intraclass correlation coefficient was 0.57. After selection of the 73.1% most accurate reporting parents, the ICC was 0.90. In general, parents estimate the dental fear of their children higher than their children do (P ≤ 0.001), whereas parents of high anxious children (HAC) estimate this fear lower, and parents of low anxious children (LAC) estimate this fear higher. Anxious parents (AP) estimate the dental fear of their children significantly higher than nonanxious parents (NAP) (P ≤ 0.001), but the children of AP do not estimate their own dental fear higher than children of NAP. In general, parents tend to estimate the dental fear of their children slightly higher than their children. © 2012 The Authors.

Breastfeeding, Parenting, and Infant Attachment Behaviors.

Gibbs, Benjamin G; Forste, Renata; Lybbert, Emily

2018-04-01

Objectives Infants and toddlers need secure attachments in order to develop the social competence required to successfully navigate later peer and adult relationships. Breastfeeding is a parenting factor that has been associated with child emotional development-specifically the attachment between children and their mothers. Yet, this link may simply be the result of other parenting behaviors that are associated with breastfeeding. Thus, our objective is to examine whether the link between infant attachment behaviors and breastfeeding endures when accounting for a broad array of in-depth measures of parenting. Methods We use the Early Childhood Longitudinal Study of children from 9 months to 2 years of age collected by the National Center for Education Statistics. Using Ordinary Least Squares regression, data analyses examine the association between the Toddler Attachment Sort-45 (TAS-45) measures of toddler-parent attachment (infant attachment security and temperamental dependency) and breastfeeding practices. We also examine individual items of the TAS-45 to isolate specific attachment behaviors that have the strongest associations with breastfeeding. Results We find an enduring link between children who are predominantly breastfed for six or more months and infant attachment security. However, we find no evidence that breastfeeding is linked to a child's temperamental dependency. Of the nine items used to examine infant attachment behaviors, we find that breastfed children are rated as having slightly higher scores on two measures ("warm and cuddly," "cooperative") and lower scores on one measure ("demanding/angry"). Conclusions for Practice Breastfeeding has an important link to the child's use of their caregiver as a secure base for exploration and a place of comfort when distressed (infant attachment security). Yet, breastfeeding does not appear to reduce a child's temperamental dependency or level of clinginess as measured by how demanding, fussy or

A Rethinking of the Production Approach in IPCC: Its Objectiveness in China

Full Text Available The trade of harvested wood products (HWPs and their feedstock increasingly affects the dynamics of the complete national HWP carbon pool ignored by the Production Approach (PA, the current universal method, proposed by the Intergovernmental Panel on Climate Change. Existing research also overlooks the inherent factors that lead to the non-objectiveness of PA that affects the potential carbon trade and the sustainable use of forestry resources. This study aimed to investigate such inherent factors through a deductive derivation of PA and the Stock-Change Approach (SCA, based on which an empirical study on China was conducted to rethink the objectiveness of PA in the complete national HWP carbon pool. The deductive derivation indicated that the inherent factors rely on the balance between coefficients that describe the relationship between HWP trade and production and the relationship between the corresponding feedstock trade and production. The empirical study further illustrated that the dynamics of balance between coefficients negatively influence the objectiveness of PA. The absolute objectiveness of this approach was constantly weakened in the past 55 years and may potentially occur yet again in the future despite an improvement in its annual relative objectiveness.

Objective To provide preliminary descriptive data on caregiver and child weight status, parenting styles, feeding styles, and feeding practices of a small American Indian sample. Methods Participants included a subsample of American Indian caregivers (n = 23) identified from a larger study that was conducted in five states. Using previously validated instruments, means, standard deviations, and ranges for general parenting styles, feeding styles, and feeding practices were explored. Results In general, most caregivers reported healthy feeding practices. Most caregivers scored higher on responsive compared to restrictive or permissive in general parenting. Of the sample, 12 caregivers (52.2 %) were classified in the indulgent feeding style category, 5 caregivers (21.7 %) were classified as authoritative, 5 (21.7 %) uninvolved, and 1 (4.3 %) authoritarian. Conclusions More investigations are needed to explore questions raised by this study about using common tools that measure childhood obesity with American Indian families.

To evaluate and compare the performance of shear-wave elastography (SWE) for breast masses using the local shear wave speed (m/sec) vs. Young modulus (kPa). A total of 130 breast lesions in 123 women who underwent SWE before ultrasound- guided core needle biopsy or surgical excision were included. With the region-of-interest placed over the stiffest areas of the lesion on SWE, the quantitative mean, maximum, and standard deviation (SD) of the elasticity values were measured in kPa and m/sec for each lesion. The SD was also measured with the region-of-interest including the whole breast lesion (wSD). The area under the receiver operating characteristic curve (AUC), sensitivity, and specificity of each elasticity value measured in kPa and m/sec were compared. Of the 130 lesions, 49 (37.7%) were malignant and 81 (62.3%) were benign. The AUCs for the mean, maximum, and SD of the elasticity values using kPa and m/sec did not differ significantly: mean, 0.974 vs. 0.974; maximum, 0.960 vs. 0.976; SD, 0.916 vs. 0.916. However, the AUC for wSD showed a significant difference: 0.964 (kPa) vs. 0.960 (m/sec) (P=0.036). There was no significant difference in the sensitivity and specificity of the mean, maximum, and wSD of the elasticity values. However, the specificity of the SD was significantly different between the two different measurements: 95.1% (kPa) vs. 87.7% (m/sec) (P=0.031). The quantitative elasticity values measured in kPa and m/sec on SWE showed good diagnostic performance. The specificity of the SD and AUC of the wSD measured in kPa were significantly higher than those measured in m/sec.

Parents' empowerment is advocated to promote and preserve an informed and autonomous decision regarding their children' immunization. The scope of this study is to develop and evaluate the psychometric properties of an instrument to measure parents' psychological empowerment in their children's vaccination decision and propose a context-specific definition of this construct. Grounding in previous qualitative data, we generated an initial pool of items which was later content and face validated by a panel of experts. A pretest allowed us to reduce the initial pool to 9 items. Convergent and discriminant validity measures included the General Self-Efficacy Scale, a Psychological Empowerment Scale, and the Control Preference Scale. Vaccination-related outcomes such as attitude and intention were also included. Principal Component Analysis revealed a 2-factor structure, with each factor composed of 2 items. The first factor concerns the perceived influence of one's personal and family experience with vaccination, while the second factor represents the desire not to ask other parents about their experience with vaccination and their lack of interest in other parents' vaccination opinion. In light of its association with positive immunization-related outcomes, public health efforts should be directed to reinforce parents' empowerment.

Children and families affected by rare diseases have received scant consideration from the medical, scientific, and political communities, with parents' needs especially having received little attention. Affected parents often have limited access to information and support and appropriate health care services. While scales to measure the needs of parents of children with chronic illnesses have been developed, there have been no previous attempts to develop a scale to assess the needs of parents of children with rare diseases. To develop a scale for measuring the supportive care needs of parents of children with rare diseases. A total of 301 responses to our Parental Needs Survey were randomly divided into two halves, one for exploratory factor analysis and the other for confirmatory factor analysis (CFA). After removing unsuitable items, exploratory factor analysis was undertaken to determine the factor structure of the data. CFA using structural equation modeling was then undertaken to confirm the factor structure. Seventy-two items were entered into the CFA, with a scree plot showing a likely four-factor solution. The results provided four independent subscales of parental needs: Understanding the disease (four items); Working with health professionals (four items); Emotional issues (three items); and Financial needs (three items). The structural equation modeling confirmed the suitability of the four-factor solution and demonstrated that the four subscales could be added to provide an overall scale of parental need. This is the first scale developed to measure the supportive care needs of parents of children with rare diseases. The scale is suitable for use in surveys to develop policy, in individual clinical assessments, and, potentially, for evaluating new programs. Measuring the supportive care needs of parents caring for a child with a rare disease will hopefully lead to better physical and psychological health outcomes for parents and their affected

Collective and single-particle excitations in the heavy deformable nuclei 234U, 233U, 231Th, 230Pa and 232Pa

2010-01-01

In this thesis five heavy deformed isotopes from the mass region A≥230, namely 234 U, 233 U, 231 Th, 230 Pa and 232 Pa, were investigated by means of deuteron-induced neutron transfer reactions. The even-even isotope 234 U has been studied with the 4π-γ-spectrometer MINIBALL at the Cologne Tandem accelerator. Excited nuclei in the isotope 234 U were produced using the reaction 235 U(d,t) at a beam energy of 11 MeV. The target thickness was 3.5 mg/cm 2 . The analysis of the γγ-coincidence data yielded a reinterpretation of the level scheme in 12 cases. Considering its decay characteristics, the 4 + state at an excitation energy of 1886.7 keV is a potential candidate for a two-phonon vibrational state. The isotopes 233 U, 231 Th, 230 Pa and 232 Pa were investigated at the Munich Q3D spectrometer. For each isotope an angular distribution with angles between 5 and 45 were measured. In all four cases the energy of the polarized deuteron beam (vector polarization of 80%) was 22 MeV. As targets 234 U (160 μg/cm 2 ), 230 Th (140 μg/cm 2 ) and 231 Pa (140 μg/cm 2 ) were used. The experimental angular distributions were compared to results of DWBA calculations. For the odd isotope 233 U spin and parity for 33 states are assigned and in the other odd isotope 231 Th 22 assignments are made. The excitation spectra of the two odd-odd isotopes 230 Pa and 232 Pa were investigated for the first time. For the isotope 230 Pa 63 states below an excitation energy of 1.5 MeV are identified. Based on the new experimental data the Nilsson configuration of the ground state is either 1/2[530] p -5/2[633] n or 1/2[530] p +3/2[631] n . In addition 12 rotational bands are proposed and from this six values for the GM splitting energy are deduced as well as two new values for the Newby shift. In the other odd-odd isotope 232 Pa 40 states below an excitation energy of 850 keV are observed and suggestions for the groundstate band and its GM partner are made. From this one GM splitting

Development of shearography for surface strain measurement of non planar objects

International Nuclear Information System (INIS)

Groves, Roger Michael

2001-01-01

The subject of this thesis is the development of optical instrumentation for surface strain measurement of non-planar objects. The speckle interferometry technique of shearography is used to perform quantitative measurements of surface strain on non-planar objects and to compensate these measurements for the errors that are due to the shape and slope of the object. Shearography is an optical technique that is usually used for defect location and for qualitative strain characterisation. In this thesis a multi-component shearography system is described that can measure the six components of displacement gradient. From these measurements the surface strain can be fully characterised. For non-planar objects an error is introduced into the displacement gradient measurement due to the variation of the sensitivity vector across the field of view and the variation in the magnitude of applied shear due to the curvature of the object surface. To correct for these errors requires a knowledge of the slope and shape of the object. Shearography may also be used to measure object slope and shape by a source displacement technique. Therefore slope, shape and surface strain may be measured using the same optical system. The thesis describes a method of multiplexing the shear direction using polarisation switching, a method of measuring the source position using shadow Moire and the shearography source displacement technique for measuring the surface slope and shape of objects. The multi-component shearography system is used to perform measurements of the six components of surface strain, on an industrial component, with a correction applied for errors due to the shape and slope of the object.

Research addressing parent-child communication on the topic of alcohol use relies heavily on assessing frequency of discussions and general assessments of openness in parent-child communication, ignoring the complexity of this communication phenomenon. This study adds to the literature by articulating a conceptualization and developing a measurement of parent-child communication—targeted parent-child communication about alcohol—and comparing the efficacy of targeted parent-child communication...

Assessing parent affect is important because studies examining the parent-child dyad have shown that parent affect has a profound impact on parent-child interactions and related outcomes. Although some measures that assess general affect during daily lives exist, to date there are only few tools that assess parent affect in the context of feeding. The aim of this study was to develop an instrument to measure parent affect specific to the feeding context and determine its validity and reliability. A brief instrument consisting of 20 items was developed that specifically asks how parents feel during the feeding process. This brief instrument draws on the structure of a well-validated general affect measure. A total of 296 Hispanic and Black Head Start parents of preschoolers completed the Feeding Emotions Scale along with other parent-report measures as part of a larger study designed to better understand feeding interactions during the dinner meal. Confirmatory factor analysis supported a two-factor model with independent subscales of positive affect and negative affect (Cronbach's alphas of 0.85 and 0.84, respectively). Concurrent and convergent construct validity was evaluated by correlating the subscales of the Feeding Emotions Scale with positive emotionality and negative emotionality from the Differential Emotions Scale - a measure of general adult emotions. Concurrent and convergent criterion validity was evaluated by testing mean differences in affect across parent feeding styles using ANOVA. A significant difference was found across maternal weight status for positive feeding affect. The resulting validated measure can be used to assess parent affect in studies of feeding to better understand how interactions during feeding may impact the development of child eating behaviors and possibly weight status.

The feasibility of an innovative biomedical diagnostic technique, thermal photoacoustic (TPA) measurement, for nonionizing and non-invasive assessment of bone health is investigated. Unlike conventional photoacoustic PA methods which are mostly focused on the measurement of absolute signal intensity, TPA targets the change in PA signal intensity as a function of the sample temperature, i.e. the temperature dependent Grueneisen parameter which is closely relevant to the chemical and molecular properties in the sample. Based on the differentiation measurement, the results from TPA technique is less susceptible to the variations associated with sample and system, and could be quantified with improved accurately. Due to the fact that the PA signal intensity from organic components such as blood changes faster than that from non-organic mineral under the same modulation of temperature, TPA measurement is able to objectively evaluate bone mineral density (BMD) and its loss as a result of osteoporosis. In an experiment on well established rat models of bone loss and preservation, PA measurements of rat tibia bones were conducted over a temperature range from 370 C to 440 C. The slope of PA signal intensity verses temperature was quantified for each specimen. The comparison among three groups of specimens with different BMD shows that bones with lower BMD have higher slopes, demonstrating the potential of the proposed TPA technique in future clinical management of osteoporosis.

A new nuclide 239 Pa was produced by 50MeV/u 18 O bombardment of uranium. A radiochemical separation method was employed for preparing sources of 239 Pa. The protactinium isotope 239 Pa has been identified for the first time by the results observed from the decay of the 239 Pa and its daughter 239 U. The half-life of 239 Pa has been determined to be 106±30min. (orig.)

ε-Caprolactam migration from irradiated PA-6 food packaging: kinetic simulation and measurement

Migration of low molecular mass compounds (LMMC), such as monomers and additives, from plastic packaging into food simulants is a very important issue, concerning public health and chemical contamination of foods. Sterilization of food packaging materials with ionizing radiation is considered an alternative to other sterilization methods, but when polymers are irradiated, LMMC may be formed, as radiolysis products. According to the Brazilian legislation, specific migration tests, such as those of LMMC from packaging into simulants, should be carried out at certain temperature and time, depending on the real conditions of contact. In this work, multilayer flexible films with polyamide 6 (PA-6), used for meat foodstuffs, were studied. The ε-caprolactam (PA-6 monomer) specific migration into acetic acid 3% simulant at 40 deg C during 10 days and at 100 deg C during 30 minutes was performed. The initial monomer level in the irradiated and non irradiated PA-6 films was quantified by high resolution gas chromatography (HRGC). Radiation doses were 3 and 7 kGy. ε-caprolactam specific migration was carried out only with non irradiated films. The results showed that radiation causes a significant change in the monomer level, up or down, depending on the multilayer film type. The kinetic of the ε-caprolactam migration at both temperatures, 40 and 100 deg C was clearly explained by the numerical simulation, combining an Arrhenius equation with the Fick's second law, although this kinetic was not experimentally studied. This simulation allowed to predict diffusion parameters estimates, like diffusion coefficients and activation energies of ε-caprolactam in the films or simulant. (author)

Measurements Conducted on an Unknown Object Labeled Pu-239

Hoteling, Nathan

2013-01-01

Measurements were carried out on 12 November 2013 to determine whether Pu-239 was present on an object discovered in a plastic bag with label ''Pu-239 6 uCi''. Following initial survey measurements to verify that the object was not leaking or contaminated, spectra were collected with a High Purity Germanium (HPGe) detector with object positioned in two different configurations. Analysis of the spectra did not yield any direct evidence of Pu-239. From the measured spectra, minimum detectable activity (MDA) was determined to be approximately 2 uCi for the gamma ray measurements. Although there was no direct evidence of Pu-239, a peak at 60 keV characteristic of Am-241 decay was observed. Since it is very likely that Am-241 would be present in aged plutonium samples, this was interpreted as indirect evidence for the presence of plutonium on the object. Analysis of this peak led to an estimated Pu-239 activity of 0.02-0.04 uCi, or <1x10 -6 grams.

Whether occupational physical activity (PA) will be assessed via questionnaires or accelerometry depends on available resources. Although self-reported data collection seems feasible and inexpensive, obtained information could be biased by demographic determinants. Thus, we aimed at comparing self-reported and objectively measured occupational sitting, standing, and walking times adjusted for socio-demographic variables. Thirty-eight office employees (eight males, 30 females, age 40.8 ± 11.4 years, BMI 23.9 ± 4.2 kg/m(2)) supplied with height-adjustable working desks were asked to report sitting, standing, and walking times using the Occupational Sitting and Physical Activity Questionnaire during one working week. The ActiGraph wGT3X-BT was used to objectively measure occupational PA during the same week. Subjectively and objectively measured data were compared computing the intra-class correlation coefficients, paired t tests and Bland-Altman plots. Furthermore, repeated-measurement ANOVAs for measurement (subjective vs. objective) and socio-demographic variables were calculated. Self-reported data yielded a significant underestimation of standing time (13.3 vs. 17.9%) and an overestimation of walking time (12.7 vs. 5.0%). Significant interaction effects of age and measurement of standing time (F = 6.0, p = .02, ηp(2) = .14) and BMI group and measurement of walking time were found (F = 3.7, p = .04, ηp(2) = .17). Older employees (>39 years) underestimated their standing time, while underweight workers (BMI < 20 kg/m(2)) overestimated their walking time. Self-reported PA data differ from objective data. Demographic variables (age, BMI) affect the amount of self-reported misjudging of PA. In order to improve the validity of self-reported data, a correction formula for the economic assessment of PA by subjective measures is needed, considering age and BMI.

Full Text Available Ethnic minority children living in high poverty neighborhoods are at high risk of having insufficient physical activity (PA during school days and, thus, the importance of school as a place to facilitate PA in these underserved children has been largely emphasized. This study examined the levels and patterns of PA in minority children, with particular focus on the relative contributions of regular physical education (PE and school-based afterschool PA program in promoting moderate- and vigorous-intensity PA (MVPA during school days. PA data were repeatedly measured using a Polar Active accelerometer across multiple school days (M = 5.3 days per child, from seventy-five ethnic minority children attending a Title I public elementary school in a high-poverty neighborhood in the US. The minutes and percentage of MVPA accumulated during school, PE, and afterschool PA program were compared to the current recommendations (≥30-min of MVPA during school hours; and ≥50% of MVPA during PE or afterschool PA program as well as by the demographic characteristics including sex, grade, ethnicity, and weight status using a general linear mixed model that accounts for repeated observations. On average, children spent 41.6 mins (SE = 1.8 of MVPA during school hours and of those, 14.1 mins (SE = 0.6 were contributed during PE. The average proportion of time spent in MVPA during PE was 31.3% (SE = 1.3, which was significantly lower than the recommendation (≥50% of MVPA, whereas 54.2% (SE = 1.2 of time in afterschool PA program were spent in MVPA. The percentage of monitoring days meeting current recommendations were 69.5% (SE = 0.03, 20.8% (SE = 0.02, and 59.6% (SE = 0.03 for during school, PE, and afterschool PA program, respectively. Our findings highlighted that school-based afterschool PA, in addition to regular PE classes, could be of great benefit to promote PA in minority children during school days. Further research and practice are still needed to

Cultural heritage is an invaluable example of human culture and creativity. The majority of them can become unstable or can be destroyed due to a combination of human and natural disturbances. In order to restore, preserve, and systematize data about architectural heritage objects, it is necessary to have geodetic, photogrammetric measurements of such data and to constantly monitor condition of the objects. The data of immovable cultural objects for many years are stored in photogrammetric data archives. Such archives have Germany, Lithuania, England and other countries. The article gives a brief introduction of the history of data archives formation and presents a photogrammetric and modern methods of modelling the spatial geometric properties of objects currently used to reveal immovable cultural properties and to evaluate geometric sizes. The pilot work was done with the Concept Capture simulation program that was developed by the Bentley company with photos of the Blessed Virgin Mary painting in Pivašiūnai of Trakai district. A shot from the ground with 12.4 MP resolution Pentax K-x camera was done using lenses with different focal lengths. The painting of the Blessed Virgin Mary is coordinated by 4 reference geodesic points and therefore after the modelling work it was possible to evaluate the accuracy of the created model. Based on the results of the spatial (3D) model, photo shooting and modelling recommendations are presented, the advantages of the new technology are distinguished.

Fibrinolytics such as recombinant tissue plasminogen activator (rt-PA) are used to treat thrombotic disease such as acute myocardial infarction (AMI) and ischemic stroke. Interest in increasing efficacy and reducing side effects has led to the study of adjuncts such as GP IIb-IIIa inhibitors and ultrasound (US) enhanced thrombolysis. Currently, GP IIb-IIIa inhibitor and fibrinolytic treatment are often used in AMI, and are under investigation for stroke treatment. However, little is known of the efficacy of combined GP IIb-IIIa inhibitor, fibrinolytic and ultrasound treatment. We measure the lytic efficacy of rt-PA, eptifibatide (Epf) and 120 kHz ultrasound treatment in an in-vitro human clot model. Blood was drawn from 15 subjects after IRB approval. Clots were made in 20 microL pipettes, and placed in a water tank for microscopic visualization during lytic treatment. Clots were exposed to control, rt-PA (rt-PA), eptifibatide (Epf), or rt-PA+eptifibatide (rt-PA + Epf), with (+US) or without (-US) ultrasound for 30 minutes at 37 degrees C in human plasma. Clot lysis was measured over time, using a microscopic imaging technique. The fractional clot loss (FCL) and initial lytic rate (LR) were used to quantify lytic efficacy. LR values for (- US) treated clots were 0.8+/-0.1(control), 1.8+/-0.3 (Epf), 1.5+/-0.2 (rt-PA), and 1.3+/-0.4 (rt-PA + Epf) (% clot width/minute) respectively. In comparison, the (+ US) group exhibited LR values of 1.6+/-0.2 (control), 4.3+/-0.4 (Epf), 6.3+/-0.4 (rt-PA), and 4.6+/-0.6 (rt-PA + Epf). For (- US) treated clots, FCL was 6.0+/-0.8 (control), 9.2+/-2.5 (Epf), 15.6+/-1.7 (rt-PA), and 28.0+/-2.2% (rt-PA + Epf) respectively. FCL for (+ US) clots was 13.5+/-2.4 (control), 20.7+/-6.4 (Epf), 44.4+/-3.6 (rt-PA) and 30.3+/-3.6% (rt-PA + Epf) respectively. Although the addition of eptifibatide enhances the in-vitro lytic efficacy of rt-PA in the absence of ultrasound, the efficacy of ultrasound and rt-PA is greater than that of combined

In Iceland, there is a large variation in daylight between summer and winter. The aim of the study was to identify how this large variation influences physical activity (PA) and sedentary behavior (SB). Free living PA was measured by a waist-worn accelerometer for one week during waking hours in 138 community-dwelling older adults (61.1% women, 80.3 ± 4.9 years) during summer and winter months. In general, SB occupied about 75% of the registered wear-time and was highly correlated with age (β = 0.36). Although the differences were small, more time was spent during the summer in all PA categories, except for the moderate-to-vigorous PA (MVPA), and SB was reduced. More lifestyle PA (LSPA) was accumulated in ≥5-min bouts during summer than winter, especially among highly active participants. This information could be important for policy makers and health professionals working with older adults. Accounting for seasonal difference is necessary in analyzing SB and PA data.

Gloss standards are commonly defined for gloss measurement from flat surfaces, and, accordingly, glossmeters are typically developed for flat objects. However, gloss inspection of convex, concave, and small products is also important. In this paper, we define statistical gloss parameters for curved objects and measure gloss data on convex and concave surfaces using two different diffractive-optical-element-based glossmeters. Examples of measurements with the two diffractive-optical-element-based glossmeters are given for convex and concave aluminum pipe samples with and without paint. The defined gloss parameters for curved objects are useful in the characterization of the surface quality of metal pipes and other objects.

Parenting programs integrating general parenting and health behaviour messaging may be an effective childhood obesity prevention strategy. The current study explored workplaces as an alternate setting to deliver parenting programs. This study involved two phases. The objective of the first phase was to explore interest in and preferred delivery mode of a workplace program that addresses general parenting and health behaviours. The objective of the second phase was to adapt and test the feasibility and acceptability of a pre-existing program that has been successfully run in community settings for parents in their workplace. To achieve the first objective, we conducted 9 individual or small group qualitative interviews with 11 workplace representatives involved in employee wellness/wellness programming from 8 different organizations across Southwestern Ontario. To achieve the second objective, we adapted a pre-existing program incorporating workplace representatives' suggestions to create Parents Working Together (PWT). We then tested the program using a pre/post uncontrolled feasibility trial with 9 employees of a large manufacturing company located in Guelph, Ontario. Results from the qualitative phase showed that a workplace parenting program that addresses general parenting and health behaviour messages is of interest to workplaces. Results from the feasibility trial suggest that PWT is feasible and well received by participants; attendance rates were high with 89 % of the participants attending 5 or more sessions and 44 % attending all 7 sessions offered. All participants stated they would recommend the program to co-workers. Just over half of our parent participants were male (55.6 %), which is a unique finding as the majority of existing parenting programs engage primarily mothers. Impact evaluation results suggest that changes in children's and parents' weight-related behaviours, as well as parents' reports of family interfering with work were in the

Reversing the obesity epidemic requires the development and evaluation of childhood obesity intervention programs. Lifestyle Triple P is a parent-focused group program that addresses three topics: nutrition, physical activity, and positive parenting. Australian research has established the efficacy of Lifestyle Triple P, which aims to prevent excessive weight gain in overweight and obese children. The aim of the current randomized controlled trial is to assess the effectiveness of the Lifestyle Triple P intervention when applied to Dutch parents of overweight and obese children aged 4-8 years. This effectiveness study is called GO4fit. Parents of overweight and obese children are being randomized to either the intervention or the control group. Those assigned to the intervention condition receive the 14-week Lifestyle Triple P intervention, in which they learn a range of nutritional, physical activity and positive parenting strategies. Parents in the control group receive two brochures, web-based tailored advice, and suggestions for exercises to increase active playing at home. Measurements are taken at baseline, directly after the intervention, and at one year follow-up. Primary outcome measure is the children's body composition, operationalized as BMI z-score, waist circumference, and fat mass (biceps and triceps skinfolds). Secondary outcome measures are children's dietary behavior and physical activity level, parenting practices, parental feeding style, parenting style, parental self-efficacy, and body composition of family members (parents and siblings). Our intervention is characterized by a focus on changing general parenting styles, in addition to focusing on changing specific parenting practices, as obesity interventions typically do. Strengths of the current study are the randomized design, the long-term follow-up, and the broad range of both self-reported and objectively measured outcomes.

The objective of this research was to identify retrospectively the alienating behaviors and the parental bonding that occurred in an Italian sample of adults whose had parents separated or divorced and their associations with self-esteem and psychological distress. Four hundred seventy adults in Chieti, Italy, completed an anonymous and confidential survey regarding their childhood exposure to parental alienating behaviors (using the Baker Strategy Questionnaire), quality of the parent-child relationship (using Parental Bonding Instruments), self-esteem (using Rosenberg Self-Esteem Scale), and global psychological distress (using Global Severity Index of Symptom Checklist-90-Revised). About 80% of the sample reported some exposure to parental alienating behaviors; about 65-70% of the sample has perceived non-optimal parenting by mother and by father; individuals who experienced affectionless control (low care and high overprotection) reported significantly higher exposure to parental loyalty conflict behaviors. Overall rates of reported exposure to low care, and overprotection and parental loyalty conflict behaviors were statistically significantly associated with self-esteem as well as the measure of current psychological distress. RESULTS revealed that exposure to parental loyalty conflict behaviors and self-esteem were associated with psychological distress over and above the effects of parental bonding and age. The pattern of findings supports the theory that children exposed to dysfunctional parenting, and with low self-esteem are at risk for their long-term psychological functioning. Implications for health policy changes and strengthening social services are discussed.

Sadeh, Avi; Mindell, Jodi; Rivera, Luis

Sleep problems are highly prevalent in early childhood. In many cases, parents seek professional help when they suspect their child suffers from a sleep problem. The aim of this study was to explore sleep, demographic and cultural factors associated with parental definition of child sleep problem in a large-scale, cross cultural study. Parents (or caregivers) of 29,287 infants and toddlers (aged 0-3 years) from 17 countries completed a questionnaire on their child's sleep patterns, sleep setting, and demographic variables. The results indicated that, in comparison to parents from predominantly Caucasian (PC) countries, parents from predominantly Asian (PA) countries were significantly more likely to identify a sleep problem in their children (26% vs 52% overall; 2% vs 17% "severe" sleep problem). Furthermore, whereas infant sleep variables were strong predictors of a sleep problem definition in PC countries, they were significantly less predictive in PA countries where demographic variables played a significant role. These results highlight the need to further explore the role of demographic and cultural variables in determining parental perception of a sleep problem, a perception that relates to help seeking professional treatment for infant sleep problems. Our findings also emphasize the need to educate parents about infant and toddler sleep and to provide parents information and screening tools to help them identify sleep problems in a more evidence-based approach.

Migration of low molecular mass compounds (LMMC), such as monomers and additives, from plastic packaging into food simulants is a very important issue, concerning public health and chemical contamination of foods. Sterilization of food packaging materials with ionizing radiation is considered an alternative to other sterilization methods, but when polymers are irradiated, LMMC may be formed, as radiolysis products. According to the Brazilian legislation, specific migration tests, such as those of LMMC from packaging into simulants, should be carried out at certain temperature and time, depending on the real conditions of contact. In this work, multilayer flexible films with polyamide 6 (PA-6), used for meat foodstuffs, were studied. The {epsilon}-caprolactam (PA-6 monomer) specific migration into acetic acid 3% simulant at 40 deg C during 10 days and at 100 deg C during 30 minutes was performed. The initial monomer level in the irradiated and non irradiated PA-6 films was quantified by high resolution gas chromatography (HRGC). Radiation doses were 3 and 7 kGy. {epsilon}-caprolactam specific migration was carried out only with non irradiated films. The results showed that radiation causes a significant change in the monomer level, up or down, depending on the multilayer film type. The kinetic of the {epsilon}-caprolactam migration at both temperatures, 40 and 100 deg C was clearly explained by the numerical simulation, combining an Arrhenius equation with the Fick's second law, although this kinetic was not experimentally studied. This simulation allowed to predict diffusion parameters estimates, like diffusion coefficients and activation energies of {epsilon}-caprolactam in the films or simulant. (author)

While the household context is important for lifestyle behavior interventions, few studies have examined parent-child associations for diet and physical activity (PA) changes over time in a rapidly urbanizing country. We aimed to investigate changes in diet, screen time, and PA behaviors over time in children and their parents living in the same household, and examine the parent-child association for these behaviors. We studied dietary, screen time, and PA behaviors in 5,201 parent-child pairs (children aged 7-17y) using longitudinal data from the China Health and Nutrition Survey (1991, 1993, 1997, 2000, 2004, 2006, and 2009). We collected three-day 24-h recall diet data to generate percentages of energy from animal-source foods, away-from-home eating, and snacking from 1991-2009, which are known urbanization-related behaviors. We used a seven-day PA recall to collect screen time (hours/week) and leisure-time sports participation (yes/no) since 2004. We examined the changes in children's and parents' behaviors over time using random-effects negative binomial regression for diet and screen time, and random-effects logistic regression for leisure-time sports. We then regressed each of the behaviors of offspring on each of their parents' same behaviors to examine the parent-child association, using the same set of models. We observed increases in energy from animal-source foods, eating away-from-home, and snacking, as well as screen time and leisure-time sports in parents and children over time, with different rates of change between children and their parents for some behaviors. We found positive parent-child associations for diet, screen time, and PA. When parental intakes increased by 10 % energy from each dietary behavior, children's increase in intakes ranged from 0.44 to 1.59 % total energy for animal-source foods, 0.17 % to 0.45 % for away-from-home eating, and 2.13 % to 7.21 % for snacking. Children were also more likely to participate in leisure

The rationale for undertaking this review was to investigate a potential strategy to address the rising prevalence of child and adolescent mental health disorders. The central tenants of mindful parenting appear to be emotional awareness, emotional regulation, attention regulation, intentionality and non-judgmental acceptance. The primary objective of this review was to systematically evaluate the effectiveness of mindful parenting programs in promoting children's, adolescents' and parents' wellbeing, particularly in relation to the intensity of symptoms associated with internalizing (depression, anxiety, stress) and externalizing (conduct) disorders. The secondary objective was to evaluate how effective mindful parenting programs are in improving emotional regulation, attention regulation, quality of the parent-child relationship, resilience and mindfulness of the children, adolescents and parents. Children aged between 0 and 18 years and their parents who have completed a mindful parenting program were the focus of this review. Mindful parenting programs included in this review had a minimum duration of one to two hours per week for 6 to 8 weeks, delivered in a group format, by a facilitator with appropriate training. It included parenting programs that drew upon mindfulness-based stress reduction, mindfulness-based cognitive therapy, mindfulness-based cognitive behavior therapy, dialectical behavior therapy or acceptance commitment therapy. The comparator was the control or waitlist conditions. This review focused on randomized controlled trials evaluating the effectiveness of mindful parenting programs. Primary outcomes were wellbeing or intensity of symptoms associated with internalizing disorders (depression, anxiety, stress) and externalizing disorders (conduct disorders) in children, adolescents and parents. Secondary outcomes were emotional regulation, quality of the parent-child relationship, resilience and mindfulness of the children, adolescents and

The optimal targets and strategies for effectively reducing sedentary behavior among young people are unknown. Intervention research that explores changes in mediated effects as well as in outcome behaviors is needed to help inform more effective interventions. Therefore, the purpose of this study was to examine the mid-intervention mediating effects on children's objectively assessed classroom and total weekday sedentary time in the Transform-Us! intervention. The results are based on 293 children, aged 7- to 9-years-old at baseline, from 20 schools in Melbourne, Australia. Each school was randomly allocated to one of four groups, which targeted reducing sedentary time in the school and family settings (SB; n = 74), increasing or maintaining moderate- to vigorous-intensity physical activity in the school and family settings (PA; n = 75), combined SB and PA (SB + PA; n = 80), or the current practice control (C; n = 64). Baseline and mid-intervention data (5-9 months) were collected in 2010 and analyzed in 2012. Classroom and total weekday sedentary time was objectively assessed using ActiGraph accelerometers. The hypothesized mediators including, child enjoyment, parent and teacher outcome expectancies, and child perceived access to standing opportunities in the classroom environment, were assessed by questionnaire. The SB + PA group spent 13.3 min/day less in weekday sedentary time at mid-intervention compared to the control group. At mid-intervention, children in the SB group had higher enjoyment of standing in class (0.9 units; 5-unit scale) and all intervention groups had more positive perceptions of access to standing opportunities in the classroom environment (0.3-0.4 units; 3-unit scale), compared to the control group. However, none of the hypothesized mediator variables had an effect on sedentary time; thus, no mediating effects were observed. While beneficial intervention effects were observed on some hypothesized mediating

Proteasome Activators, PA28α and PA28β, Govern Development of Microvascular Injury in Diabetic Nephropathy and Retinopathy

Directory of Open Access Journals (Sweden)

Saeed Yadranji Aghdam

2016-01-01

Full Text Available Diabetic nephropathy (DN and diabetic retinopathy (DR are major complications of type 1 and type 2 diabetes. DN and DR are mainly caused by injury to the perivascular supporting cells, the mesangial cells within the glomerulus, and the pericytes in the retina. The genes and molecular mechanisms predisposing retinal and glomerular pericytes to diabetic injury are poorly characterized. In this study, the genetic deletion of proteasome activator genes, PA28α and PA28β genes, protected the diabetic mice in the experimental STZ-induced diabetes model against renal injury and retinal microvascular injury and prolonged their survival compared with wild type STZ diabetic mice. The improved wellbeing and reduced renal damage was associated with diminished expression of Osteopontin (OPN and Monocyte Chemoattractant Protein-1 (MCP-1 in the glomeruli of STZ-injected PA28α/PA28β double knockout (Pa28αβDKO mice and also in cultured mesangial cells and retinal pericytes isolated from Pa28αβDKO mice that were grown in high glucose. The mesangial PA28-mediated expression of OPN under high glucose conditions was suppressed by peptides capable of inhibiting the binding of PA28 to the 20S proteasome. Collectively, our findings demonstrate that diabetic hyperglycemia promotes PA28-mediated alteration of proteasome activity in vulnerable perivascular cells resulting in microvascular injury and development of DN and DR.

The current study examined the congruence of parent and adolescent reports of positive and negative parenting with observations of parent-adolescent interactions as the criterion measure. The role of parent and adolescent depressive symptoms in moderating the associations between adolescent or parent report and observations of parenting also was examined. Participants were 180 parents (88.9% female) with a history of clinical depression and one of their 9-to-15 year old children (49.4% female...

To examine the agreement between self-reported and objectively assessed physical activity (PA) according to current public health recommendations. One-hundred and fourteen British University students wore a combined accelerometer and heart rate monitor (Actiheart; AHR) to estimate 24-hour energy expenditure over 7 consecutive days. Data were extracted based on population-based MET-levels recommended to improve and maintain health. On day 8, participants were randomly assigned to complete either the short-form International Physical Activity Questionnaire (IPAQ) or the Leisure-Time Exercise Questionnaire (LTEQ). Estimates of duration (IPAQ; N = 46) and frequency (LTEQ; N = 41) of PA were compared with those recorded by the AHR. Bland-Altman analysis showed the mean bias between the IPAQ and AHR to be small for moderate-intensity and total PA, however the 95% limits of agreement (LOA) were wide. The mean number of moderate bouts of PA estimated by the LTEQ was similar to those derived by the AHR but the 95% LOA between the 2 measures were large. Although self-report questionnaires may provide an approximation of PA at a population level, they may not determine whether an individual is participating in the type, intensity, and amount of PA advocated in current public health recommendations. ©2011 Human Kinetics, Inc.

Full Text Available Abstract Background Parenting programs integrating general parenting and health behaviour messaging may be an effective childhood obesity prevention strategy. The current study explored workplaces as an alternate setting to deliver parenting programs. Methods This study involved two phases. The objective of the first phase was to explore interest in and preferred delivery mode of a workplace program that addresses general parenting and health behaviours. The objective of the second phase was to adapt and test the feasibility and acceptability of a pre-existing program that has been successfully run in community settings for parents in their workplace. To achieve the first objective, we conducted 9 individual or small group qualitative interviews with 11 workplace representatives involved in employee wellness/wellness programming from 8 different organizations across Southwestern Ontario. To achieve the second objective, we adapted a pre-existing program incorporating workplace representatives’ suggestions to create Parents Working Together (PWT. We then tested the program using a pre/post uncontrolled feasibility trial with 9 employees of a large manufacturing company located in Guelph, Ontario. Results Results from the qualitative phase showed that a workplace parenting program that addresses general parenting and health behaviour messages is of interest to workplaces. Results from the feasibility trial suggest that PWT is feasible and well received by participants; attendance rates were high with 89 % of the participants attending 5 or more sessions and 44 % attending all 7 sessions offered. All participants stated they would recommend the program to co-workers. Just over half of our parent participants were male (55.6 %, which is a unique finding as the majority of existing parenting programs engage primarily mothers. Impact evaluation results suggest that changes in children’s and parents’ weight-related behaviours, as well as

Full Text Available ABSTRACT Some difficulties may arise during the divorce process, taking the family into “destructive divorce”. In such cases, some authors can see the rising of Parental Alienation (PA. This article aims to criticize PA, reflecting about the Family Life Cycle and divorce. Regarding this, a qualitative study was conducted with legal actors (judges, prosecutors, psychologists, social workers, lawyers on the issues of divorce and PA and the results were built using the conceptions of Zones of Sense by Gonzalez Rey. The summary results are: (a PA does not contextualize the conflict; (b it does not consider the history of the relationships; (c it pathologizes, medicates and criminalizes the phenomena of post-divorce and (d PA underestimates the child in the conflict.

Child feeding practices and parenting style each have an impact on child dietary intake, but it is unclear whether they influence each other or are amenable to change. The aims of this study were to measure child feeding and parenting styles in the Feeding Healthy Food to Kids (FHFK) Randomized Controlled Trial (RCT) and test a composite child feeding score and a composite parenting style score. Child feeding and parenting style data from 146 parent-child dyads (76 boys, aged 2.0-5.9 years) in the FHFK study were collected over a 12-month intervention. Parenting style was measured using parenting questions from the Longitudinal Study of Australian Children and the Child Feeding Questionnaire (CFQ) was used to measure child feeding practices. Data for both measures were collected at baseline, 3 and 12 months and then modelled to develop a composite child feeding score and a parenting score. Multivariate mixed effects linear regression was used to measure associations between variables over time. All child feeding domains from the CFQ were consistent between baseline and 12 months ( p parenting style domain scores were consistent over 12 months ( p parenting style score within the FHFK RCT. In conclusion, composite scores have potential applications in the analysis of relationships between child feeding and dietary or anthropometric data in intervention studies aimed at improving child feeding or parenting style. These applications have the potential to make a substantial contribution to the understanding of child feeding practices and parenting style, in relation to each other and to dietary intake and health outcomes amongst pre-school aged children.

Full Text Available The fast development in the fields of integrated circuits, photovoltaics, the automobile industry, advanced manufacturing, and astronomy have led to the importance and necessity of quickly and accurately obtaining three-dimensional (3D shape data of specular surfaces for quality control and function evaluation. Owing to the advantages of a large dynamic range, non-contact operation, full-field and fast acquisition, high accuracy, and automatic data processing, phase-measuring deflectometry (PMD, also called fringe reflection profilometry has been widely studied and applied in many fields. Phase information coded in the reflected fringe patterns relates to the local slope and height of the measured specular objects. The 3D shape is obtained by integrating the local gradient data or directly calculating the depth data from the phase information. We present a review of the relevant techniques regarding classical PMD. The improved PMD technique is then used to measure specular objects having discontinuous and/or isolated surfaces. Some influential factors on the measured results are presented. The challenges and future research directions are discussed to further advance PMD techniques. Finally, the application fields of PMD are briefly introduced.

Parenting is an often-studied correlate of children's physical activity, however there is little research examining the associations between parenting styles, practices and the physical activity of younger children. This study aimed to investigate whether physical activity-based parenting practices mediate the association between parenting styles and 5-6 year-old children's objectively-assessed physical activity. 770 parents self-reported parenting style (nurturance and control) and physical activity-based parenting practices (logistic and modeling support). Their 5-6 year old child wore an accelerometer for five days to measure moderate-to-vigorous physical activity (MVPA). Linear regression was used to examine direct and indirect (mediation) associations. Data were collected in the United Kingdom in 2012/13 and analyzed in 2014. Parent nurturance was positively associated with provision of modeling (adjusted unstandardized coefficient, β = 0.11; 95% CI = 0.02, 0.21) and logistic support (β = 0.14; 0.07, 0.21). Modeling support was associated with greater child MVPA (β = 2.41; 0.23, 4.60) and a small indirect path from parent nurturance to child's MVPA was identified (β = 0.27; 0.04, 0.70). Physical activity-based parenting practices are more strongly associated with 5-6 year old children's MVPA than parenting styles. Further research examining conceptual models of parenting is needed to understand in more depth the possible antecedents to adaptive parenting practices beyond parenting styles.

Evaluate psychometric properties of a measure of adolescents’ observations of parental pain behaviors and use this measure to test hypotheses regarding pain-specific social learning. We created a proxy-report of the Patient Reported Outcomes Measurement Information System (PROMIS) Pain Behavior–Short Form (PPB) for adolescents to report on parental pain behaviors, which we labeled the PPB-Proxy. Adolescents (n = 138, mean age = 14.20) with functional abdominal pain completed the PPB-Proxy and a parent completed the PPB. Adolescents and their parents completed measures of pain and disability during the adolescent’s clinic visit for abdominal pain. Adolescents subsequently completed a 7-day pain diary period. The PPB-Proxy moderately correlated with the PPB, evidencing that adolescents observe and can report on parental pain behaviors. Both the PPB-Proxy and PPB significantly correlated with adolescents’ pain-related disability. Parental modeling of pain behaviors could represent an important target for assessment and treatment in pediatric chronic pain patients.

A community sample of 262 European American mothers of firstborn 20-month-olds completed a personality inventory and measures of parenting cognitions (knowledge, self-perceptions, and reports about behavior) and was observed in interaction with their children from which measures of parenting practices (language, sensitivity, affection, and play) were independently coded. Factor analyses of the personality inventory replicated extraction of the Five-Factor model of personality (Openness, Neuroticism, Extraversion, Agreeableness, and Conscientiousness). Controlling for sociodemographic characteristics, the five personality factors qua variables and in patterns qua clusters related differently to diverse parenting cognitions and practices, supporting the multidimensional, modular, and specific nature of parenting. Maternal personality in the normal range, a theoretically important but empirically neglected factor in everyday parenting, has meaning in studies of parenting, child development, and family process.

To explore whether changes in parenting self-efficacy after attending a parenting programme are related to changes in parenting stress and child behaviour. Adverse parenting is a risk factor in the development of a range of health and behavioural problems in childhood and is predictive of poor adult outcomes. Strategies for supporting parents are recognised as an effective way to improve the health, well-being and development of children. Parenting is influenced by many factors including the behaviour and characteristics of the child, the health and psychological well-being of the parent and the contextual influences of stress and support. Parenting difficulties are a major source of stress for parents, and parenting self-efficacy has been shown to be an important buffer against parenting stress. In all, 63 parents who had a child under the age of 10 years took part in the research. Of those, 58 returned completed measures of parenting self-efficacy, parenting stress and child behaviour at the start of a parenting programme and 37 at three-month follow-up. Improvements in parenting self-efficacy and parenting stress were found at follow-up, but there was less evidence for improvements in child behaviour. The findings clearly suggest a relationship between parenting self-efficacy and parenting stress; parents who are feeling less efficacious experience higher levels of stress, whereas greater parenting self-efficacy is related to less stress. This study adds to the evidence that parent outcomes may be a more reliable measure of programme effectiveness than child outcomes at least in the short term.
