    Age and gender are two important physiological variables which might influence the personality of an individual. The influence of age and gender on big five personality domains in Indian population was assessed in this cross-sectional study that included 155 subjects (female = 76, male = 79) aged from 16-75 years. Big five personality factors were evaluated using 60-item NEO-Five Factor Inventory (NEO-FFI) at a single point in time. Among the big five factors of personality, Conscientiousness was positively correlated (r = 0.195; P personality traits might change with age, and is gender-dependent.

    To describe the cardiovascular risk factors in a working population in the Balearic Islands and to examine whether differences by social class vary according to age and gender. A cross-sectional study was carried out in a sample of active workers aged 20-65 years in the Balearic Islands. The participants were included in the study during their annual work health assessment in 2011. The following variables were collected: occupation, social class, age, gender, height, weight, smoking, blood pressure, lipid profile, and glucose levels. Cardiovascular risk was calculated using two different equations (Framingham and REGICOR). Differences by social class were observed for most cardiovascular risk factors. The pattern of these differences differed depending on age group and gender. Differences in obesity by social class increased with age in women but decreased in men. More differences in hypertension by social class were found among women than among men, with differences increasing with age in both genders. Significant differences by social class were found among women in lipid profile, and these differences increased with age, mainly for low levels of high-density lipoprotein-cholesterol. Inequalities in cardiovascular risk factors by social class were higher among women than among men. Some cardiovascular risk factors such as smoking and obesity showed significant inequalities from a very early age. Copyright © 2014 SESPAS. Published by Elsevier Espana. All rights reserved.

    Full Text Available Introduction: Intima-media thickness (IMT measurement of the common carotid artery (CCA is considered as useful indicator of carotid atherosclerosis. Early detection of atherosclerosis and its associated risk factors is important to prevent stroke and heart diseases. The aim of the present study was to investigate which risk factors are better determinants of subclinical atherosclerosis, measured by common carotidartery intima media thickness (CCA-IMT.Methods: A total of 74 subjects were randomly selected in this cross – sectional study. Information on the patient’s medical history and laboratory fi ndings were obtained from their clinical records. Risk factors relevant to this study were age, gender, cigarette smoking status, diabetes, hypertension and dyslipidemia. Ultrasound scanning of carotid arteries was performed with a 7,5 MHz linear array transducer (GE Voluson730 pro. The highest value of six common carotid artery measurements was taken as the fi nal IMT. Increased CCA-IMT was defi ned when it was > 1 mm.Results: Our data demonstrated higher CCA-IMT values in male patients compared with female patients. Increased CCA-IMT was the most closely related to age (PConclusion: Age, gender and hypertension are the most important risk factors in development of carotid atherosclerosis. Early detection of atherosclerosis among high-risk populations is important in order to prevent stroke and heart diseases, which are leading causes of death worldwide.

    Four samples, representing a broad age range, were compared in confirmatory factor analyses with respect to a four-factor model of aberrant driving behaviour. With the restrictions imposed on the data by the model, an approximate fit was obtained for all four samples. Additional analyses, which tested equality of factor loadings and correlations for different age groups, also indicated that the model was a good fit. Separate analyses on male and female respondents yielded similar results. Although earlier results have shown that aberrant driving behaviours are differentially related to age and gender, the findings suggest that structural differences in relation to age and gender may be of minor importance. The four-factor model of aberrant driving behaviour sufficiently meets statistical criteria in a model-generating phase. In addition, it is an appropriate solution to apply on data obtained from respondents varying in age and gender.

    BACKGROUND AND AIMS: The influence of gender and age on risk factor prediction of coronary artery calcification (CAC) in symptomatic patients is unclear. METHODS: From the European Calcific Coronary Artery Disease (EURO-CCAD) cohort, we retrospectively investigated 6309 symptomatic patients, 62......% male, from Denmark, France, Germany, Italy, Spain and USA. All of them underwent risk factor assessment and CT scanning for CAC scoring. RESULTS: The prevalence of CAC among females was lower than among males in all age groups. Using multivariate logistic regression, age, dyslipidaemia, hypertension......, diabetes and smoking were independently predictive of CAC presence in both genders. In addition to a progressive increase in CAC with age, the most important predictors of CAC presence were dyslipidaemia and diabetes (β = 0.64 and 0.63, respectively) in males and diabetes (β = 1.08) followed by smoking (β...

    Full Text Available Background. Evidences are accumulating that age and gender have great impact on the distribution of stroke risk factors. Such data are lacking in Chinese population. Methods. 1027 patients with first-ever ischemic stroke (IS were recruited and divided into young adult (80 years groups according to stroke onset ages. Vascular risk factors were collected and compared among groups. Results. Female patients were globally older than male patients at stroke onset and having higher prevalence of diabetes mellitus (DM, heart diseases, and atrial fibrillation (AF. However, females were less likely to drink heavily or smoke than males. Young patients had a much higher proportion of smoking and drinking than middle-aged and very old patients and the highest family history of hypertension, while very old patients had the highest prevalence of heart diseases and AF but lowest proportion of positive family history of vascular diseases. Hypertension and DM were equally frequent among three groups. Conclusion. Our study showed that vascular risk factors had a specific age and gender distribution pattern in Chinese IS patients. Secondary prevention strategy should emphasize on the control of different risk factors based on patient’s age and gender.

    The aims of this study were to identify if the associations of physical activity (PA) and muscle strength may vary throughout the ageing process; to study the differences among genders in the relationships between PA and strength in elderly people and to test whether these differences are explained by the hormonal, nutritional and inflammatory status. A total of 1741 people ≥65 years of age participated in this cross-sectional study. Upper- and lower-limbs maximal voluntary isometric strength was obtained using standardized techniques and equipment. PA was recorded by a validated questionnaire. The associations of PA with strength were assessed using generalized linear regression models with a Gamma-distributed dependent variable. A significant gender by PA interaction was found for all strength-related variables (all P<0.01). Moreover, when sexual hormones, albumin or C-Reactive protein were taken into account in the model, the results did not significantly change. In women, PA was positively associated with upper and lower-body strength; however in men, PA was only associated with grip and knee strength (both P<0.01). Higher strength values were associated with higher levels of PA, especially in women. However, this tendency had a different pattern across the age range, showing a stronger association in the 'young' elderly compared with the 'old' elderly. Higher levels of PA are related to greater muscle strength, especially in women and those who were younger. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    So far in Europe, no large studies have been published on the frequencies of the cardiovascular risk factors hypertension and dyslipidaemia in overweight children. Diagnosis of hypertension, decreased HDL-cholesterol, increased triglycerides, total and LDL-cholesterol were documented for 1004 overweight children and adolescents (aged 4-8 years, 52% girls, BMI-SDS in median 2.43) referred to four obesity centres. Hypertension and dyslipidaemia were defined by cut off points above the 95th percentile of healthy children. Multivariate linear regression was conducted for the dependent variables systolic and diastolic blood pressure, triglycerides, HDL-, LDL-, and total cholesterol, including gender, degree of overweight (SDS-BMI) and age as independent variables. Thirty-seven percent of the children studied suffered from hypertension, 27% displayed increased total cholesterol, 26% increased LDL-cholesterol, 20% increased triglycerides and 18% decreased HDL-cholesterol. Seventy percent of all children had at least one unfavourable cardiovascular risk factor. Hypertension and dyslipidaemia were observed in any age group and in any degree of overweight at least twofold above the suspected rate of 5%. SDS-BMI was significantly related to blood pressure (systolic: coefficient 7.26, p European children and adolescents. They occurred mostly independently of age, gender and degree of overweight. Therefore, screening for cardiovascular risk factors seems meaningful at any age and degree of overweight in childhood.

    The Student-Teacher Relationship Scale (STRS) is widely used to examine teachers' relationships with young students in terms of closeness, conflict, and dependency. This study aimed to verify the dimensional structure of the STRS with confirmatory factor analysis, test its measurement invariance across child gender and age, improve its measurement of the dependency construct, and extend its age range. Teachers completed a slightly adapted STRS for a Dutch sample of 2335 children aged 3 to 12. Overall, the 3-factor model showed an acceptable fit. Results indicated metric invariance across gender and age up to 8years. Scalar invariance generally did not hold. Lack of metric invariance at ages 8 to 12 primarily involved Conflict items, whereas scale differences across gender and age primarily involved Closeness items. The adapted Dependency scale showed strong invariance and higher internal consistencies than the original scale for this Dutch sample. Importantly, the revealed non-invariance for gender and age did not influence mean group comparisons.

    Psychological stress due to social isolation is known to cause abnormal feeding behaviors, but the influences of gender and aging on subchronic stress-induced changes in feeding behaviors are unknown. Thus, we examined the changes in body weight, food intake, and orexigenic ghrelin-related factors during 2 weeks of isolation stress in young and aged mice. Food intake increased significantly in young mice in the isolation group compared with the group-housed control throughout the experimental period. This isolation-induced increase in food intake was not observed in aged mice. In young mice, there were no significant differences in body weight between the isolated group and group-housed control up to 2 weeks. However, aged male mice exhibited significant weight loss at 2 weeks and a similar tendency was observed in aged female mice. Young male mice, but not female mice, had significantly increased (2.2-fold) plasma acylated ghrelin levels after 1 week of isolation compared with the group-housed control. A significant but lower increase (1.3-fold) was also observed in aged male mice. Hypothalamic preproghrelin gene expression decreased significantly with isolation in young male mice, whereas it increased significantly in female mice. The expression levels of NPY and AGRP in the hypothalamus, which are transmitted by elevated peripheral ghrelin signals, increased significantly in isolated young male mice, whereas the AGRP expression levels decreased significantly in young female mice. Isolation caused no significant differences in the expression levels of these genes in aged mice. In isolation, young female mice exhibited markedly increased dark- and light-phase locomotor activities compared with male mice, whereas male and female aged mice exhibited no obvious increases in activity immediately after the dark phase started. We conclude that the gender-specific homeostatic regulatory mechanisms required to maintain body weight operated during subchronic psychological

    Full Text Available Health status is often analyzed in population surveys. Self-rated health (SRH is a single-item summary measure of the perception of one's health. In Brazil, studies on the SRH of adolescents remain scarce, especially those aiming to understand the domains that compose this construct. Therefore, the aim of this study is to determine the prevalence of poor SRH and its associated factors among 11- to 13-year-olds and 14- to 17-year-olds living in a large urban center in Brazil. This cross-sectional study was conducted using a household survey across Belo Horizonte that included 1,042 adolescents. Stratified logistic regression models were used for each age group to assess the associations between worse SRH and the following variables: socio-demographic, social and family support, lifestyles, psychological health, and anthropometry. Approximately 11% (95% CIs = 8.7-13.6 of the studied adolescents rated their health as poor, and SHR decreased with age among males and females. This trend was more pronounced among girls (from 6.9% among 11- to 13-year-old girls to 16.9% among 14- to 17-year-old girls than boys (from 8.3% among 11- to 13-year-old boys to 11% among 14- to 17-year-old boys. Worse SRH was associated with family support (as assessed by the absence of parent-adolescent conversations; odds ratio [OR] = 3.5 among 11- to 13-year-olds, family structure (OR = 2.8 among 14- to 17-year-olds, and argument reporting (OR = 8.2 among 14- to 17-year-olds. Among older adolescents, the consumption of fruit fewer than five times per week (OR = 2.4, life dissatisfaction (OR = 2.8, underweight status (OR = 6.7, and overweight status (OR = 2.7 were associated with poor SRH. As adolescents age, their universe expands from their relationship with their parents to include more complex issues, such as their lifestyles and life satisfaction. Therefore, these results suggest the importance of evaluating SRH across adolescent age groups and demonstrate the influence

    Hundred consecutive suicide attempters admitted in the Medical Intensive Care Unit(MlCU) of Christian Medical College, Vellore during the period December 1991 to December 1992 were evaluated in detail with respect to all psycho-socio-demographic variables. Instruments used included a specially designed sociodemographic proforma, Gurmeet Singh's Presumptive Stressful Life Event Scale, Suicide Intent Questionnaire and DSM III R Diagnostic Criteria. Young males constituted major part of the sample. Organophosphorus poisoning was the commonest mode of suicide attempt. More than 90% had psychiatric diagnosis. Adjustment disorder was the commonest psychiatric diagnosis followed by major depression and alcohol abuse/dependence. Many of the risk factors reported earlier was found to be operating in older age group only. Among males the commonest mode of attempt was organophosphorus poisoning whereas in females it was drug over dose and native poisoning. The implication of these findings are discussed in the context of prevention and further management strategies. PMID:21494498

    Objectives We examined the social distribution of a comprehensive range of cardiovascular risk factors (CVRF) in a Swiss population and assessed whether socioeconomic differences varied by age and gender. Methods Participants were 2960 men and 3343 women aged 35–75 years from a population-based survey conducted in Lausanne, Switzerland (CoLaus study). Educational level was the indicator of socioeconomic status used in this study. Analyses were stratified by gender and age group (35–54 years; 55–75 years). Results There were large educational differences in the prevalence of CVRF such as current smoking (Δ = absolute difference in prevalence between highest and lowest educational group:15.1%/12.6% in men/women aged 35–54 years), physical inactivity (Δ = 25.3%/22.7% in men/women aged 35–54 years), overweight and obesity (Δ = 14.6%/14.8% in men/women aged 55–75 years for obesity), hypertension (Δ = 16.7%/11.4% in men/women aged 55–75 years), dyslipidemia (Δ = 2.8%/6.2% in men/women aged 35–54 years for high LDL-cholesterol) and diabetes (Δ = 6.0%/2.6% in men/women aged 55–75 years). Educational inequalities in the distribution of CVRF were larger in women than in men for alcohol consumption, obesity, hypertension and dyslipidemia (p<0.05). Relative educational inequalities in CVRF tended to be greater among the younger (35–54 years) than among the older age group (55–75 years), particularly for behavioral CVRF and abdominal obesity among men and for physiological CVRF among women (p<0.05). Conclusion Large absolute differences in the prevalence of CVRF according to education categories were observed in this Swiss population. The socioeconomic gradient in CVRF tended to be larger in women and in younger persons. PMID:23152909

    Background/ Aims: Despite the existence of an easy tool to diagnose biliary tract disease as an etiology for acute pancreatitis (AP), the sensitivity of abdominal ultrasound is around 80%, which can be even lower in certain conditions. We have retrospectively reviewed data of 146 patients admitted for acute pancreatitis between 1999 and 2013. Bivariate analysis for clinical and biochemical variables was performed with respect to etiology of AP (biliary versus non-biliary). Multivariate analysis was performed by using binary logistic regression. There were 87 males (59.6%) and 59 females (40.4%), with a median age of 51. The etiology of acute pancreatitis was biliary in 71 patients (48.6%). Bivariate analysis found the following as significant association (p=0.001) with biliary pancreatitis: older age, female gender, and elevated AST, ALT. A binary logistic regression analysis identified as predictor factors for biliary etiology of acute pancreatitis: age OR = 1.031 (95% CI 1.004 - 1.059, p = 0.024), sex (female) OR = 2.34 (95% CI 1.022 - 5.359, p = 0.044) and ALT OR = 1.004 (95% CI 1.001 - 1.007, p =0.004). The two clinical scores included the three variables (A.S.ALT scores) in categorical format were generated and then checked with the ROC curves (areas under curve are 0.768 and 0.778). Age, female gender, and elevated ALT can help identifying cases with biliary etiology of acute pancreatitis.

    Background: The relationships that age and gender share with risk factors (RFs) of noncommunicable diseases (NCDs) were assessed among a large-scale employ in Western Iran. Methods: In this epidemiologic cross-sectional study, 7129 employees from Kermanshah Province were assessed using a census method in 2012. Data on RFs of NCD were collected using a standard questionnaire. Demographic information, diet, physical activity, tobacco use, and history of hypertension, history of diabetes, cardiovascular diseases, osteoporosis, and cancer were studied. Results: The proportion of ≥5 servings of fruits and vegetables consumption per day was lower in higher ages (P = 0.001), and this proportion was greater in females than males (72.1% vs. 47.8%; P < 0.0001). Tobacco use was more in higher ages and was higher among males than females (13.3% vs. 0.6%; P < 0.0001). Overweight and obesity prevalence increased in higher ages and was more prominent among males than females (67.8% vs. 55.3%; P < 0.0001). Overall, the prevalence of having 3–5 RFs was greater among those with ≥55 years and among males than females (20.4% vs. 6.6%; P < 0.0001). Conclusions: The prevalence of major RFs of NCDs was greater among older persons and male participants. More preventive programs such as health education on employees of Kermanshah are recommended.

    Full Text Available Despite the marked increase of diverticulosis, its risk factors have not been adequately elucidated. We therefore aim to identify significantly associated factors with diverticulosis. We also aim to investigate the present state of diverticulosis in Japan.We reviewed the medical records from 1990 to 2010 that included the data of consecutive 62,503 asymptomatic colonoscopy examinees from the general population in Japan. Most recent 3,327 examinees were analyzed with 16 background factors.Among the 62,503 subjects (47,325 men and 15,178 women; 52.1 ± 9.2 years old, diverticulosis was detected in 11,771 subjects (18.8%; 10,023 men and 1,748 women. The incidences of diverticulosis in 1990-2000 and 2001-2010 were respectively 13.0% (3,771 of 29,071 and 23.9% (8,000 of 33,432: the latter was much higher than the former in all age groups and for both genders. Considering the anatomical locations of colorectal diverticula, left-sided ones have markedly increased with age but not significantly changed with times. Univariate analyses of the 3,327 subjects showed significant association of diverticulosis with four basic factors (age, sex, body mass index, blood pressure, three life style-related factor (smoking, drinking, severe weight increase in adulthood, and two blood test values (triglyceride, HbA1c. The multiple logistic analysis calculating standardized coefficients (β and odds ratio (OR demonstrated that age (β = 0.217-0.674, OR = 1.24-1.96, male gender (β = 0.185, OR = 1.20, smoking (β = 0.142-0.200, OR = 1.15-1.22, severe weight increase in adulthood (β = 0.153, OR = 1.17, HbA1c (β = 0.136, OR = 1.15, drinking (β = 0.109, OR = 1.11, and serum triglyceride (β = 0.098, OR = 1.10 showed significantly positive association with diverticulosis whereas body mass index and blood pressure did not.The large-scale data of asymptomatic colonoscopy examinees from the general population from 1990 to 2010 indicated that the prevalence of

We also aim to investigate the present state of diverticulosis in Japan. We reviewed the medical records from 1990 to 2010 that included the data of consecutive 62,503 asymptomatic colonoscopy examinees from the general population in Japan. Most recent 3,327 examinees were analyzed with 16 background factors. Among the 62,503 subjects (47,325 men and 15,178 women; 52.1 ± 9.2 years old), diverticulosis was detected in 11,771 subjects (18.8%; 10,023 men and 1,748 women). The incidences of diverticulosis in 1990-2000 and 2001-2010 were respectively 13.0% (3,771 of 29,071) and 23.9% (8,000 of 33,432): the latter was much higher than the former in all age groups and for both genders. Considering the anatomical locations of colorectal diverticula, left-sided ones have markedly increased with age but not significantly changed with times. Univariate analyses of the 3,327 subjects showed significant association of diverticulosis with four basic factors (age, sex, body mass index, blood pressure), three life style-related factor (smoking, drinking, severe weight increase in adulthood), and two blood test values (triglyceride, HbA1c). The multiple logistic analysis calculating standardized coefficients (β) and odds ratio (OR) demonstrated that age (β = 0.217-0.674, OR = 1.24-1.96), male gender (β = 0.185, OR = 1.20), smoking (β = 0.142-0.200, OR = 1.15-1.22), severe weight increase in adulthood (β = 0.153, OR = 1.17), HbA1c (β = 0.136, OR = 1.15), drinking (β = 0.109, OR = 1.11), and serum triglyceride (β = 0.098, OR = 1.10) showed significantly positive association with diverticulosis whereas body mass index and blood pressure did not. The large-scale data of asymptomatic colonoscopy examinees from the general population from 1990 to 2010 indicated that the prevalence of diverticulosis

    Playing-related musculoskeletal problems (PRMP) are common in adult musicians, and risk factors include gender, music exposure, and particularly instrument type. Emerging evidence suggests PRMP are common in children and adolescents and that risk factors may be similar. The aim of this study was to determine the prevalence of PRMP, both symptoms and disorders, and PRMP location in children and adolescents as well as the associations with gender, age, and music exposure factors such as type and number of instruments and playing time. This study surveyed 731 children (460 females), aged 7 to 17 years, studying instrumental music in government schools in Perth, Australia. Lifetime and monthly symptoms, monthly disorders (inability to play an instrument as usual), and PRMP location were examined. Chi-squared analyses were used to evaluate associations between gender, age, music exposure, and PRMP outcomes. Logistic regression evaluated the independent association of these potential risk factors with PRMP prevalence and location. RESULTS) Sixty-seven percent of students reported PRMP symptoms at some point, 56% reported them within the last month, and 30% reported an inability to play as usual within the last month. After adjustment for gender and age, the type of instrument played (upper and lower strings, woodwind, and brass) was significantly associated with all PRMP (pmusic exposure are associated with PRMP risk and need to be addressed to ensure musicians' personal well-being and musical longevity.

    The flexion-rotation test (FRT) is commonly used when assessing cervicogenic headache. Additionally, active range of motion (AROM) is frequently used to evaluate impairment in neck pain. No studies have investigated the interaction of the FRT and AROM with age, gender, pain and lifestyle factors. The purpose of this study was to determine the influence of these factors on the FRT and cervical AROM. A group of 66 participants (aged 20-78) were studied, 28 experienced sub-clinical neck pain (recurrent neck pain or discomfort which has not received treatment from a healthcare professional) while 38 did not. Age, gender, lifestyle factors and sub-clinical neck pain were assessed using a questionnaire. Measurement of AROM was performed by two examiners blind to the results of the questionnaire. Multiple linear regression analysis found that 59% of the variance in the FRT was explained by the presence of sub-clinical pain and cervical lateral flexion measures. Secondly, 58-72% of the variance in active cervical ROM measures was influenced by factors including the FRT, gender and movements of the neck in other planes. This study found that lifestyle factors do not influence the cervical FRT and AROM.

    The purpose of this study was to investigate the relationships among gender, age, and intellectual development. Random samples of 70 females and 70 males were selected with each sex group equally divided into a low-age and a high-age group. The low-age group ranged in age from 16.25 years to 16.75 years and the high-age group from 16.76 years to 17.25 years. The Piaget tasks selected to measure cognitive development were: Conservation of Volume, Separation of Variables, and Equilibrium in the Balance and Combination of Colorless Chemical Liquids. Data from this research produced these findings: (1) males demonstrate a higher level of intellectual development than females, (2) males mature intellectually earlier than females, (3) the value of the conservation of volume task as a component of a battery of formal tasks depends upon whether the decisions are to be made on the basis of the total-task results or on individual task performance, and (4) there appear to be factors other than age and gender that are related to the development of formal operational reasoning. These investigators hypothesize that experiences is another important factor.

    Full Text Available Background: New information and communication technologies have become an important part of adolescents' everyday lives. However, the sedentary behaviour of young people in Central Europe has become more similar to that found in Western European countries. This study can provide baseline data for a future comparison and investigation of lifestyle and health behaviours in this region in the future. Objective: The aim of this study is to assess country, age, and gender differences in the prevalence of sedentary behaviour activities and family-related factors among school-aged children. Methods: Using the methodology of the Health Behaviour in School-aged Children (HBSC study was performed in 2013, collecting data from 11- and 15-year-old Slovak (n = 488 and Czech (n = 418 children. The data was explored using c2 tests to determine statistical significance. Results: Two-thirds of the respondents watch television or use a computer for at least two hours a day. The older children (older vs. younger: 73.6% vs. 53.9%, c2 = 35.6, p < .001 spent excessive amounts of time watching television. More than half of the children have a television (51.9% or a computer (73.0% in their bedroom. More than half of their parents rarely or never apply rules about how long they can watch TV (63.9% or time spent on the computer (55.5%. The Slovak children reported watching television together with their parents every day significantly more frequently than their Czech peers (Slovak vs. Czech children 31.0% vs. 18.7%, c2 = 17.9, p < .001. Conclusions: The prevalence of screen-based behaviour is relatively high, as is screen time spent together with parents, especially among the Slovak children. Moreover, many children reported that their parents rarely or never applied rules about the length and content of their television watching or time spent on the computer.

    Cognitive aging processes are underpinned by multiple processes including genetic factors. The brain-derived neurotrophic factor (BDNF) has been suggested to be involved in age-related cognitive decline in otherwise healthy individuals. The gender-specific role of the BDNF gene in cognitive aging remains unclear. The identification of genetic biomarkers might be a useful approach to identify individuals at risk of cognitive decline during healthy aging processes. The aim of this study was to investigate the associations between three single-nucleotide polymorphisms (SNPs) in the BDNF gene and domains of cognitive functioning in normal cognitive aging. The sample, comprising 369 participants (M = 72.7 years, SD = 4.45 years), completed an extensive neuropsychological test battery measuring memory, motor function, and perceptual speed. The relationships between the SNPs rs6265, rs7103411, and rs7124442 and cognitive domains were examined. While significant main effects of BDNF SNPs on cognitive function were found for the association between rs7103411 and memory performance, gender-specific analyses revealed for females significant main effects of rs7103411 for memory and of rs6265 for perceptual speed independent of the APOE*E4 status and education. The finding for the association between rs6265 and perceptual speed in females remained significant after Bonferroni correction for multiple comparisons. None of the analyses showed significant results for males. This study is the first to implicate that the SNPs rs6265 and rs7103411 affect cognitive function in the elderly in a gender-specific way.

    Carney, Gemma M

    2017-04-04

    The article proposes a Gender Politics of Aging approach to the study of aging societies. The approach recognizes the feminization of old age, ageism's roots in sexist discourse, and the need to recognize the role of politics in driving demographic debates. Drawing together arguments from feminist gerontology and political demography, the article argues that the intersection of politics and gender must be considered if appropriate responses to an older, feminized demography are to be produced. I conclude that the work of aging feminists provides a rich vein of research and praxis from which a gender politics of aging approach can draw.

  12. Chronic Lead Exposure and Mixed Factors of Gender×Age×Brain Regions Interactions on Dendrite Growth, Spine Maturity and NDR Kinase.

    Full Text Available NDR1/2 kinase is essential in dendrite morphology and spine formation, which is regulated by cellular Ca2+. Lead (Pb is a potent blocker of L-type calcium channel and our recent work showed Pb exposure impairs dendritic spine outgrowth in hippocampal neurons in rats. But the sensitivity of Pb-induced spine maturity with mixed factors (gender×age×brain regions remains unknown. This study aimed to systematically investigate the effect of Pb exposure on spine maturity in rat brain with three factors (gender×age×brain regions, as well as the NDR1/2 kinase expression. Sprague-Dawley rats were exposed to Pb from parturition to postnatal day 30, 60, 90, respectively. Golgi-Cox staining was used to examine spine maturity. Western blot assay was applied to measure protein expression and real-time fluorescence quantitative PCR assay was used to examine mRNA levels. The results showed chronic Pb exposure significantly decreased dendritic length and impaired spine maturity in both rat hippocampus and medial prefrontal cortex. The impairment of dendritic length induced by Pb exposure tended to adolescence > adulthood, hippocampus > medial prefrontal cortex and female > male. Pb exposure induced significant damage in spine maturity during adolescence and early adult while little damage during adult in male rat brain and female medial prefrontal cortex. Besides, there was sustained impairment from adolescence to adulthood in female hippocampus. Interestingly, impairment of spine maturity followed by Pb exposure was correlated with NDR1/2 kinase. The reduction of NDR1/2 kinase protein expression after Pb exposure was similar to the result of spine maturity. In addition, NDR2 and their substrate Rabin3 mRNA levels were significantly decreased by Pb exposure in developmental rat brain. Taken together, Pb exposure impaired dendrite growth and maturity which was subject to gender×age×brain regions effects and related to NDR1/2 signal expression.

    Full Text Available Drawing on the interplay between gender, aging, and sexuality, the aim of this article is twofold: (1 to show how Brazilian gerontologists treat gender differences and sexual activity in old age; (2 to analyze the  ways  discourses regarding the aging body and sexuality are perceived and evaluated by older women and men . I argue that  attempts of gerontologists’ to eroticize old age have to contend with the widespread notion that the desire for sex is inevitably lost with age. Thus, in the retiree associations that were studied, men had a tendency to assume they are not ‘old’ because their erectile function was still in good condition, and divorced or widowed women, in senior citizen associations, tend to regard themselves as happy due to having freed themselves from the sexual obligations imposed by marriage. In both cases, the dominant belief that there is a loss of sexual desire in old age was reproduced.

    2014-08-01

    Full Text Available Social anxiety in adolescence is one of the most important factors of social and psychological maladjustment. The data of Russian and international research of the differences in the severity of social anxiety in boys and girls is not uniform. In a study conducted by the authors, participants were 183 adolescents aged 12-16 years (90 boys and 93 girls, students of VII-X grades. We measured the level of social anxiety and defined the type of gender identity. The results showed that biological sex does not influence the severity of social anxiety: there were no differences in this indicator between boys and girls. The factor influencing the level of social anxiety was gender identity, and gender identity types (masculinity, femininity, androgyny have approximately the same distributions in both boys and girls. The level of social anxiety shows inversed connection with level of masculinity in adolescents of both sexes and direct connection with femininity index. The magnitude of the gap between the real and the ideal of masculinity of the Self is more pronounced in adolescents with social anxiety disorder.

    To ascertain the major dietary patterns in the cohort 'SUN' and to assess the association of several sociodemographic (including age and gender) and lifestyle variables with the adherence to these dietary patterns. This study is a cross-sectional analysis of 3847 subjects (1587 men and 2260 women) belonging to a prospective cohort study based on self-reported questionnaires. A factor analysis based on 30 predefined food groups was conducted to ascertain the major dietary patterns in the cohort. Multiple regression models were fitted to assess the relationship between several sociodemographic and lifestyle variables and the adherence to these dietary patterns (measured using two scores with observed values ranging from -3.2 to +4.6 for the Western pattern and -3.1 to +5.5 for the Mediterranean pattern). Two major dietary patterns were found. The first pattern was labelled as a 'Western' dietary pattern and the other as a 'Spanish-Mediterranean' dietary pattern. Younger subjects were more likely to follow a 'Western' dietary pattern; the coefficient representing the change for every 10 y increase in age was b=-0.24 (P<0.001) for men and b=-0.12 (P<0.001) for women. More physically active subjects were less likely to follow a 'Western' dietary pattern and more likely to follow a 'Spanish-Mediterranean' dietary pattern. An association between a higher level of physical activity during leisure time and adherence to a 'Spanish-Mediterranean' diet was apparent. However, the profile of being a young, sedentary and single male was identified as the most likely to exhibit a departure from the traditional 'Spanish-Mediterranean' diet and follow a 'Western' dietary pattern.

  19. The influence of sexual attitudes on mid- to late-life sexual well-being: age, not gender, as a salient factor.

    Graf, Allyson S; Patrick, Julie Hicks

    2014-01-01

    The influence of sexual attitudes on sexual activity and expression has been relatively understudied in older populations. In the current study, we sought to understand the role sexual attitudes have on sexual well-being among middle-aged and young-old adults. Using a diverse sample of participants over the age of 45 (N = 384), a path model was analyzed to determine whether sexual attitudes contributed to sexual well-being. The model was then compared by gender. Results indicated: a) only age-relative sexual attitudes significantly contributed to sexual well-being; and b) the model was equally robust for both men and women, even though women held slightly more positive age-relative sexual attitudes than men. Therefore, among middle-aged and young-old adults, sexual well-being may be reduced by harboring negative ageist sexual attitudes. Efforts should be made to reduce stigma surrounding continued sexual activity and expression among the aged.

    Research on marriage in developing countries has been somewhat narrow in scope because of both conceptual and data limitations. While the feminist literature recognizes marriage as a key institutional site for the production and reproduction of gender hierarchies, little is known about the processes through which this relationship operates. This article uses data from the newly collected India Human Development Survey 2005 for 27,365 ever-married women aged 25-49 to explore ways in which different dimensions of gender in Indian society shape the decisions regarding age at marriage. We explore the impact of three dimensions of gender: (1) economic factors, such as availability of wage employment, dowry expectations, and wedding expenses; (2) indicators offamilial empowerment, such as women s role in household decision making and access to and control over resources; and (3) markers of gender performance, such as observance of purdah and male-female separation in the household. Results from hierarchical linear models confirm the importance of markers of gender performance but fail to demonstrate a large role for economic factors and familial empowerment.

    The understanding of sociolinguistic variation is growing rapidly, but basic gaps still remain. Whether some languages or dialects are spoken faster or slower than others constitutes such a gap. Speech tempo is interconnected with social, physical and psychological markings of speech. This study examines regional variation in articulation rate and its manifestations across speaker age, gender and speaking situations (reading vs. free conversation). The results of an experimental investigation show that articulation rate differs significantly between two regional varieties of American English examined here. A group of Northern speakers (from Wisconsin) spoke significantly faster than a group of Southern speakers (from North Carolina). With regard to age and gender, young adults read faster than older adults in both regions; in free speech, only Northern young adults spoke faster than older adults. Effects of gender were smaller and less consistent; men generally spoke slightly faster than women. As the body of work on the sociophonetics of American English continues to grow in scope and depth, we argue that it is important to include fundamental phonetic information as part of our catalog of regional differences and patterns of change in American English.

    Climate and society evolve together in a manner that could place already vulnerable areas and their population at a greater risk to extreme weather events. While efforts have been devoted to better planning preparedness and responses to weather extremes, the interactions among various stakeholders who deal with hazard mitigation and response, and the community members, also related with gender and age differences, are not completely understood. In contrast to physical vulnerability, which arises from the potential for environmental extremes to create adverse physiological changes, social vulnerability arises from the potential for these extreme events to cause changes in people's behavior. People can vary in their potential for injury to themselves and their families. They also vary in the potential for destruction of their homes and workplaces, as well as the destruction of the transportation systems and locations for shopping and recreation they use in their daily activities. It is important to recognize that social vulnerability is not randomly distributed either demographically or geographically. In particular, the social vulnerability arising from a lack of psychological resilience, social network integration, economic assets, and political power vary across demographic groups. Some of these components of social vulnerability can be predicted by demographic characteristics such as gender, age, education, income, and ethnicity. This review explores the gender and social difference dimensions of vulnerability and adaptive capacity in relation to climate change.

    Schizophrenia is linked with early medical comorbidity and mortality. These observations indicate possible "accelerated biological aging" in schizophrenia, although prior findings are mixed, and few such studies have examined the role of gender. One putative marker of biological aging is leukocyte telomere length (LTL), which typically shortens with age. We assessed LTL in phenotypically well characterized 134 individuals with schizophrenia (60 women and 74 men) and 123 healthy comparison subjects (HCs) (66 women and 57 men), aged 26 to 65 years. Overall, LTL was inversely associated with age (t(249) = -6.2, p schizophrenia and HC groups (t(249) = 2.48, p = 0.014), with women having longer LTL than men, and a significant gender X diagnosis effect (t(249) = 2.43, p = 0.016) - at the average sample age, women with schizophrenia had shorter LTL than HC women. Gender, not the diagnosis of schizophrenia, was the major factor involved with LTL shortening across the age range studied. We discuss the constraints of a cross-sectional design and other methodological issues, and indicate future directions. Understanding the impact of schizophrenia on biological aging will require separate evaluations in men and women. Published by Elsevier Ltd.

    Full Text Available Many of the choices which impact in lifetime health, such as substance use, are made in adolescence. It becomes, therefore, important to know the factors associated to these behaviours in adolescence in different contexts of life. To analyze these factors, an explanatory model was developed using structural equation modeling. Data from 12.881 state school students from Portugal who participated in two waves of the Health Behaviours in School-aged Children (HBSC / World Health Organization (WHO survey were analyzed. The model fits well the data [CFI: .985; NNFI: .980; RMSEA: .018 (.017-.020; SRMR: .018]. For each of the dependent factors, the levels of variance ranged from 12% (tobacco use to 47% (alcohol and illicit drugs use. Alcohol and tobacco present the strongest associations to illicit drugs use. Relationships with family, friends, classmates, and teachers were also associated with substance use, being this association mediated by certain factors, including psychological symptoms, well-being, and school satisfaction. Several non-invariant paths were obtained in gender and age comparisons. The results showed that substance use is associated with several factors and that social factors are mediated by personal factors. Results have also shown that gender and age are important factors on substance use.

    The aim of this study was to test the generalisability of the factor pattern, structural parameters, factor correlations and latent mean structure of social physique anxiety and physical self-esteem across gender, age and gender x age. The social physique anxiety scale and general physical self-esteem scale from the physical self-perception profile was administered to high school and university students aged 11-24 years (N = 2334). Confirmatory factor analysis (CFA) was used to test the adequacy of a two-factor correlated model in the full sample, and separately by gender, age and gender x age sub-samples. The CFA model satisfied criteria for goodness-of-fit with the data in all sub-samples, the only exception was for females aged 21 and over. Tests of invariance of the factor pattern, structural parameters and correlations across age, gender and age x gender revealed few decrements in goodness-of-fit. Latent means analysis revealed that females had consistently higher levels of social physique anxiety and lower levels of physical self-esteem than males, with the exception of the 11-12 age group. Results extend previous findings that females tend to report higher levels of social physique anxiety and lower levels of physical self-esteem than males by demonstrating that these differences are consistent across age group.

  14. Assessing risk factors for migraine: differences in gender transmission.

    Directory of Open Access Journals (Sweden)

    Carolina Lemos

    Full Text Available AIM: Our aim was to assess which specific factors are contributing to an increased risk of migraine in a group of 131 Portuguese families. METHODS: We studied 319 first-degree relatives, using a multilevel approach to account for the dependency among members from the same family. We included in the model relative's gender, the proband's gender and age-at-onset, to evaluate if any of these variables were associated with relative's affection status. We also included in the model proband's migraine subtype. We further assessed female and male transmissions within the proband nuclear family. RESULTS: Relatives' gender was found to be a risk factor for migraine (Odds Ratio = 2.86; 95% CI = 1.75-4.67, with females at a higher risk. When splitting probands according to their migraine subtype, we found that none of the variables studied contributed to relatives of MA-probands affection-status. Our results also show a significant difference between proband's transmission and the gender of the parents and offspring. CONCLUSIONS: With this study, we showed that gender is truly a risk factor for migraine and that a gender-biased transmission is also observed. This reinforce the importance of identifying genes associated with migraine that are modulated by genes located in the sex chromosomes and the study of mitochondrial DNA or X-chromosome and hormonal-related effects associated with migraine susceptibility.

  16. Gender-dependent effects of aging on the kidney

    Directory of Open Access Journals (Sweden)

    A.L. Gava

    2011-09-01

    Full Text Available It is well known that the kidney plays an important role in the development of cardiovascular diseases such as hypertension. The normal aging process leads to changes in kidney morphology, hemodynamics and function, which increase the incidence of cardiovascular events in the elderly population. These disturbances are influenced by several factors, including gender. In general, females are protected by the effects of estrogens on the cardiorenal system. Several studies have demonstrated the beneficial effects of estrogens on renal function in the elderly; however, the relationships between androgens and kidney health during one’s lifetime are not well understood. Sex steroids have many complex actions, and the decline in their levels during aging clearly influences kidney function, decreases the renal reserve and facilitates the development of cardiovascular disorders. Therefore, in this review, we discuss the cellular, biochemical, and molecular mechanisms by which sex hormones may influence renal function during the aging process.

    Gender differences in autobiographical memory emerge in some data collection paradigms and not others. The present study included an extensive analysis of gender differences in autobiographical narratives. Data were collected from 196 participants, evenly split by gender and by age group (emerging adults, ages 18-29, and young adults, ages 30-40). Each participant reported four narratives, including an event that had occurred in the last 2 years, a high point, a low point, and a self-defining memory. Additionally, all participants completed self-report measures of masculine and feminine gender typicality. The narratives were coded along six dimensions-namely coherence, connectedness, agency, affect, factual elaboration, and interpretive elaboration. The results indicated that females expressed more affect, connection, and factual elaboration than males across all narratives, and that feminine typicality predicted increased connectedness in narratives. Masculine typicality predicted higher agency, lower connectedness, and lower affect, but only for some narratives and not others. These findings support an approach that views autobiographical reminiscing as a feminine-typed activity and that identifies gender differences as being linked to categorical gender, but also to one's feminine gender typicality, whereas the influences of masculine gender typicality were more context-dependent. We suggest that implicit gendered socialization and more explicit gender typicality each contribute to gendered autobiographies.

    Previous studies on the significance of vitamin D insufficiency and chronic inflammation in colorectal cancer development clearly indicated that maintenance of cellular homeostasis in the large intestinal epithelium requires balanced interaction of 1,25-(OH){sub 2}D{sub 3} and prostaglandin cellular signaling networks. The present study addresses the question how colorectal cancer pathogenesis depends on alterations of activities of vitamin D hydroxylases, i.e., CYP27B1-encoded 25-hydroxyvitamin D-1α-hydroxylase and CYP24A1-encoded 25-hydroxyvitamin D-24-hydroxylase, and inflammation-induced cyclooxygenase-2 (COX-2). Data from 105 cancer patients on CYP27B1, VDR, CYP24A1, and COX-2 mRNA expression in relation to tumor grade, anatomical location, gender and age were fit into a multivariate model of exploratory factor analysis. Nearly identical results were obtained by the principal factor and the maximum likelihood method, and these were confirmed by hierarchical cluster analysis: Within the eight mutually dependent variables studied four independent constellations were found that identify different features of colorectal cancer pathogenesis: (i) Escape of COX-2 activity from restraints by the CYP27B1/VDR system can initiate cancer growth anywhere in the colorectum regardless of age and gender; (ii) variations in COX-2 expression are mainly responsible for differences in cancer incidence in relation to tumor location; (iii) advancing age has a strong gender-specific influence on cancer incidence; (iv) progression from well differentiated to undifferentiated cancer is solely associated with a rise in CYP24A1 expression.

    We investigated age and gender effects on "Positive Orientation" (POS)-an individual's tendency to view life with a positive outlook-using a genetically informed design. Study subjects were 1016 twins aged 22-75 from the Italian twin registry. We assessed POS by the recently developed P-scale. First, we used confirmatory factor analysis to investigate scale's measurement invariance by age and gender. Then, we applied biometric modelling to estimate genetic and environmental components of POS score. Overall, we found a satisfactory degree of measurement invariance by both age and gender. Results from these analyses further indicated an increasing mean level of POS across the lifespan. Additive genetic and unshared environmental factors explained respectively 58% and 42% of variance in POS score, with no significant gender differences; furthermore, the pattern of change of gene-environment architecture of POS over time was consistent with a greater plasticity of personality at older ages.

    To date, accurate reports about the prevalence of high normal blood pressure (BP) and hypertension among Chinese adolescents have been rare. We examine the sex-specific and age-specific prevalence of high normal BP and hypertension, and the associated risk factors among multi-ethnic Chinese adolescents from a large and representative sample. 29,997 adolescents aged 8-18 years old received blood pressure measurement on one clinical visit. The overall prevalence was 4.15% for hypertension (4.73% for boys and 3.62% for girls) and 29.85% for high normal BP (33.40% for boys and 26.65% for girls). The odds ratios (ORs) increased with age, but the absolute changes of ORs were significantly different between boys and girls. Compared with that of the Han counterparts, the risk of high normal BP was 1.960-fold, 1.283-fold and 1.618-fold for Yi boys, Mongolian boys and Yi girls, respectively, whereas the OR was 0.440 for Tibetan boys, 0.492 for Tibetan girls and 0.794 for Korean girls. Compared with those of normal weight, overweight and obese adolescents had significantly increased risk of high normal BP (OR = 3.377 for obese boys and OR = 2.009 for overweight boys; OR = 2.865 for obese girls and OR = 1.738 for overweight girls). Rural adolescents had a higher risk of hypertension than those living in urban areas. The prevalence of high normal BP and hypertension was high in Chinese adolescents. Age, ethnicity, obesity, overweight, abnormal waist circumference, family history of cardiovascular diseases and dwelling at rural districts were significantly associated with pediatric high normal BP or hypertension.

Material and methods We examined 210 patients with stage I gallstone disease (GSD. In verification of diagnosis used an ultrasound study of the hepatobiliary system, multi-grade duodenal sounding with subsequent macroscopic, microscopic, chemical and physical examination of bile. In the portions “b” and “C” bile was determined the total concentration of bile acids, cholesterol, with the subsequent calculation it consists of cholesterol ratio. Estimation of surface tension of bile viscosity and bile. In the studied blood levels of total cholesterol, lipoproteins of very low density, lowdensity lipoproteins, high density lipoproteins, triglycerides, were determined the coefficient of atherogenicity. To assess the degree of accumulation of body fat was used the Quetelet index. Studied the relative risk of anamnestic risk factors of GSD. Results. The features of biliary lithogenesis based on gender and age of patients. High value PR for the gall stone formation are female gender — 3,16, Mature and elderly age (older than 50 of 3.67. In young women, gall-stone formation is mainly due to the increase of cholesterol level of bile, at the age of 50 years with a decline in zhelchnokamennaja pool, increased viscosity and surface tension of bile. The most important risk factors of cholecystolithiasis are also gender differences: if women is multiple pregnancies and (or childbirth (more than 3 — OR 4,62, overweight (BMI over 26 — OR is 4.57 and the violation of the principles of good nutrition (eating disorders, overeating or starvation, the use of large quantities of animal fats — OR 3,94, for men it’s physical inactivity — OR a 4.25, the increase in KA — PR 3.87 and burdened by GSD genetics — OR of 2.05.

    This study examined the effects of daily physical activity level on health-related factors according to gender and identified age-specific differences among Korean adults. Using data from the Korea National Health and Nutrition Examination Survey VI (2014-2015), we selected adults aged 19-64 years who participated in both a health examination and health interview survey. The study included 6,457 participants 19-64 years of age (2,611 men, 3,846 women). Assessment of the differences in health-related factors according to age and physical activity in men and women by repeated two-way analysis of variance (ANOVA) revealed significant interaction effects on total cholesterol (TC) and triglyceride (TG) levels and diastolic blood pressure (DBP) in male participants, but there were no significant interaction effects for any health-related factors in female participants. The group of female participants aged 40-64 years with daily physical activity levels over 200 kcal showed a significantly increased prevalence of 46% for dyslipidemia compared to that in female participants with daily physical activity levels below 200 kcal. Physical activity was positively correlated with weight and high-density lipoprotein cholesterol (HDL-C) levels in men 19-39 years of age, compared to weight, waist circumference (WC), body mass index (BMI), and DBP in men 40-64 years of age, and weight, WC, BMI, glycated hemoglobin (HbA1c) and triglyceride (TG) levels in women 19-39 years of age. In women 40- 64 years of age, physical activity was especially significantly positively correlated with weight, BMI, HDL-C and negatively correlated with fasting glucose and TG levels. In male and female participants, the 40-64-year age group showed negative results for health-related factors compared to those in the 19-39-year age group. The higher the weight, WC, BMI, the higher is the physical activity level. Physical activity levels were significantly positively correlated with health-related variables.

    Full Text Available In this work, an automatic gender and age recognizer from speech is investigated. The relevant features to gender recognition are selected from the first four formant frequencies and twelve MFCCs and feed the SVM classifier. While the relevant features to age has been used with k-NN classifier for the age recognizer model, using MATLAB as a simulation tool. A special selection of robust features is used in this work to improve the results of the gender and age classifiers based on the frequency range that the feature represents. The gender and age classification algorithms are evaluated using 114 (clean and noisy speech samples uttered in Kurdish language. The model of two classes (adult males and adult females gender recognition, reached 96% recognition accuracy. While for three categories classification (adult males, adult females, and children, the model achieved 94% recognition accuracy. For the age recognition model, seven groups according to their ages are categorized. The model performance after selecting the relevant features to age achieved 75.3%. For further improvement a de-noising technique is used with the noisy speech signals, followed by selecting the proper features that are affected by the de-noising process and result in 81.44% recognition accuracy.

    2010-01-01

    Full Text Available The findings of the research into the perceived parental behavior provide contrasting data as to the existence and the nature of differences in the perception of parental behavior based on parents’ gender and respondents’ gender. The purpose of the present study is to examine the differences in the perceived parental behavior in adolescents with regard to parents’ gender and respondents’ age and gender. The study included 466 respondents (262 girls and 204 boys, in middle to late adolescence, divided into four sub-groups according to their age. The respondents were asked to fill in the Parental Bonding Instrument (PBI questionnaire which measures the care and overprotection in mothers and fathers respectively. The obtained findings show the existence of significant difference based on the parents’ gender for both subscales: both maternal care and maternal overprotection were estimated as higher. Observing the differences by respondents’ gender on the whole sample, only one significant difference is found: paternal overprotection was estimated as higher by girls. The differences by age as observed within gender groups are completely disparate for girl and boy groups. The best insight into the differences is obtained through analysis by gender, for groups relatively homogenous in terms of their age (for the first three groups the only significant difference appears in the paternal overprotection subscale; the difference disappears in the subgroup of the oldest respondents’, while the differences between the perception of maternal and paternal care are of significance here. One particularly important finding for future research into rearing behavior is the fact that the perception of parental behavior changes over the period of adolescence differently for boys and girls; therefore, the analysis including perceived parental behavior should be performed for subgroups by gender, which are as homogenous as possible in terms of their age.

    2003-04-01

    Eminent composers in Western European art music continue to be predominantly male and eminence in contemporary pop music is similarly male dominated. One contributing factor may be the continuing under-valuation of women's music. Possible anti-female bias in a contemporary genre was investigated using the Goldberg paradigm to elicit judgments of New Age compositions. Since stronger stereotyping effects occur when information provided about individuals is sparse, fictitious male and female composers were presented either by name only or by name with a brief biography. Evidence for anti-female bias was found in the name-only condition and was stronger when liking for the music was controlled. Other findings were the tendency for females to give higher ratings, and the association of gender differences in liking of the music with ratings of quality in the name-only condition. These results are relevant to the design of formal assessment procedures for musical composition.

    The numbers of participants over 75 years of age in previous studies of oral health have not been sufficient to permit a full investigation of the influence of age on the mouth. In this study a disproportionate stratified random sample of 255 independent elders was selected from a list of urban voters to provide similar numbers of men and women in three age groups. The subjects were interviewed and examined, and nearly half of them had mucosal disorders. There was a significant (P angular cheilitis in particular were associated significantly with men and with the use of defective dentures. Logistic regression revealed that neither age alone nor the quality of dentures predispose to mucosal lesions, but that the odds of finding stomatitis, denture-related hyperplasia and angular cheilitis in particular increased about three-fold in denture-users, and almost doubled in men.

    Mobile health (m-health) services are becoming increasingly important and widely accepted. However, empirical studies on potential users' m-health acceptance behavior remain underexplored. Indeed, m-health adoption is not only a technology acceptance behavior, but also a health-related behavior. Based on the Protection Motivation Theory, this article explores users' m-health adoption behavior from the perspectives of threat appraisal and coping appraisal, and also examines the moderating role of gender and age through a survey of potential users. The survey was conducted among 500 potential m-health service participants. Our results show that threat appraisal and coping appraisal factors influence adoption intention through attitude. It is also found that gender and age play different moderating roles with threat appraisal and coping appraisal factors. Gender and age play different roles between threat appraisal and coping appraisal factors in the acceptance of m-health. Implications for research and practice are discussed.

    Full Text Available The face recognition system with large sets of training sets for personal identification normally attains good accuracy. In this paper, we proposed Feature Extraction based Face Recognition, Gender and Age Classification (FEBFRGAC algorithm with only small training sets and it yields good results even with one image per person. This process involves three stages: Pre-processing, Feature Extraction and Classification. The geometric features of facial images like eyes, nose, mouth etc. are located by using Canny edge operator and face recognition is performed. Based on the texture and shape information gender and age classification is done using Posteriori Class Probability and Artificial Neural Network respectively. It is observed that the face recognition is 100%, the gender and age classification is around 98% and 94% respectively.

    Full Text Available Affective computing aims at the detection of users' mental states, in particular, emotions and dispositions during human-computer interactions. Detection can be achieved by measuring multimodal signals, namely, speech, facial expressions and/or psychobiology. Over the past years, one major approach was to identify the best features for each signal using different classification methods. Although this is of high priority, other subject-specific variables should not be neglected. In our study, we analyzed the effect of gender, age, personality and gender roles on the extracted psychobiological features (derived from skin conductance level, facial electromyography and heart rate variability as well as the influence on the classification results. In an experimental human-computer interaction, five different affective states with picture material from the International Affective Picture System and ULM pictures were induced. A total of 127 subjects participated in the study. Among all potentially influencing variables (gender has been reported to be influential, age was the only variable that correlated significantly with psychobiological responses. In summary, the conducted classification processes resulted in 20% classification accuracy differences according to age and gender, especially when comparing the neutral condition with four other affective states. We suggest taking age and gender specifically into account for future studies in affective computing, as these may lead to an improvement of emotion recognition accuracy.

    The world is aging, and the percentages of older people are on a dramatic ascent. This dramatic demographic aging of human society is not gender neutral; it is mostly about older women. One of the key policy approaches to address the aging revolution is known as "active aging," crystalized by the WHO in 2002 by three pillars: participation, health, and security. The active aging policy has financial and economic aspects and affects both men and women. However, as argued in this article, a gender-based approach has not been adopted within the existing active aging framework. Therefore, a new gender-specific research agenda is needed, one that focuses on an interrelation between gender and different economic aspects of "active aging" from international, comparative, cultural, and longitudinal perspectives.

    Full Text Available Considerable research has shown effects of facial appearance on trait impressions and group stereotypes. We extended those findings in two studies that investigated the contribution of resemblance to emotion expressions and attractiveness to younger adults (YA and older adults (OA age and gender stereotypes on the dimensions of warmth and competence. Using connectionist modeling of facial metrics of 240 neutral younger and older faces, Study 1 found that, neutral expression older faces or female faces showed greater structural resemblance to happy expressions and less resemblance to angry expressions than did younger or male faces, respectively. In addition, neutral female faces showed greater resemblance to surprise expressions. In Study 2, YA and OA rated the faces of Study 1 for attractiveness and for 4 traits that we aggregated on the dimensions of competence (competent, healthy and warmth (trustworthy, not shrewd. We found that YA, but not OA, age stereotypes replicated previous research showing higher perceived warmth and lower perceived competence in older adults. In addition, previously documented gender stereotypes were moderated by face age for both YA and OA. The greater attractiveness of younger than older faces and female than male faces influenced age and gender stereotypes, including these deviations from prior research findings using category labels rather than faces. On the other hand, face age and face sex differences in emotion resemblance did not influence age or gender stereotypes, contrary to prediction. Our results provide a caveat to conclusions about age and gender stereotypes derived from responses to category labels, and they reveal the importance of assessing stereotypes with a methodology that is sensitive to influences of group differences in appearance that can exacerbate or mitigate stereotypes in more ecologically valid contexts. Although the gender differences in attractiveness in the present study may not have

    To identify age and gender differences among teen drivers in fatal crashes, we analyzed FARS data for 14,026crashes during 2007-2009. Compared with female teenagers, crashes of male teenagers were significantly more likely to involve BACs of 0.08% or more (21% vs. 12%), speeding (38% vs. 25%), reckless driving (17% vs. 14%), night driving (41% vs. 36%) and felony crashes (hit-and-run, homicide, or manslaughter) (8% vs. 6%) (all χ(2) pteens to involve speeding or reckless driving. Crashes of drivers with BACs of 0.08% or higher increased with age in both genders. Some age effects differed by gender: for example, the proportion of crashes of female teens that involved speeding dropped from 38% to 22% between ages 15 and 19, while for males about 38% of crashes at each age involved speeding. The gender and age differences observed in teen drivers suggest opportunities for targeted driver training - for example, simulator training modules specifically tailored for male or female teenagers. Technology-based tools could also be developed to help parents to focus on the reckless driving tendencies of their sons. Insurance companies should consider ways to incentivize young males to drive more responsibly.

    A molecular description of the mechanisms by which aging is produced is still very limited. Here, we have determined the plasma metabolite profile by using high-throughput metabolome profiling technologies of 150 healthy humans ranging from 30 to 100 years of age. Using a nontargeted approach, we detected 2,678 metabolite species in plasma, and the multivariate analyses separated perfectly two groups indicating a specific signature for each gender. In addition, there is a set of gender-shared metabolites, which change significantly during aging with a similar tendency. Among the identified molecules, we found vitamin D2-related compound, phosphoserine (40:5), monoacylglyceride (22:1), diacylglyceride (33:2), and resolvin D6, all of them decreasing with the aging process. Finally, we found three molecules that directly correlate with age and seven that inversely correlate with age, independently of gender. Among the identified molecules (6 of 10 according to exact mass and retention time), we found a proteolytic product (l-γ-glutamyl-l-leucine), which increased with age. On the contrary, a hydroxyl fatty acid (25-hydroxy-hexacosanoic), a polyunsaturated fatty acid (eicosapentaenoic acid), two phospholipids (phosphocholine [42:9]and phosphoserine [42:3]) and a prostaglandin (15-keto-prostaglandin F2α) decreased with aging. These results suggest that lipid species and their metabolism are closely linked to the aging process.

    Full Text Available The paper devoted to the age and gender identity among the perpetrators of sexual violence against children and discussed the factors lead to pathogenesis of abnormal sexual behavior against children. We have identified particularities of gender and age identity in perpetrators of violent sexual acts against children. It was noted that patients with a diagnosis of pedophilia have abnormalities mostly in cognitive structure of sexual identity, that is shown in undifferentiated age peculiarities of perception of self-image and gender and role stereotypes. These data allow assessing more accurately the abnormalities of sexual sphere, explaining the deviant behavior, as well as structure of age and sex self-identity in persons with the disorder of sexual desire in the form of pedophilia and take a step closer to understanding the mechanisms of abnormal choice of sexual object.

    Full Text Available Age estimation has many useful applications, such as age-based face classification, finding lost children, surveillance monitoring, and face recognition invariant to age progression. Among many factors affecting age estimation accuracy, gender and facial expression can have negative effects. In our research, the effects of gender and facial expression on age estimation using support vector regression (SVR method are investigated. Our research is novel in the following four ways. First, the accuracies of age estimation using a single-level local binary pattern (LBP and a multilevel LBP (MLBP are compared, and MLBP shows better performance as an extractor of texture features globally. Second, we compare the accuracies of age estimation using global features extracted by MLBP, local features extracted by Gabor filtering, and the combination of the two methods. Results show that the third approach is the most accurate. Third, the accuracies of age estimation with and without preclassification of facial expression are compared and analyzed. Fourth, those with and without preclassification of gender are compared and analyzed. The experimental results show the effectiveness of gender preclassification in age estimation.

    Paediatric specialists involved in the care of children with disorders of sex development may be expected to provide straightforward answers to questions concerning the "true sex" of a child, reflecting common perceptions of sex/gender as an immutable binary biological reality. This article highlights how much more broad and complex the topic of gender identity and its development is. Many theories have been put forward to advance knowledge of gender identity. Against the breadth and depth of this vast topic, the current overview is inevitably incomplete. It begins by arguing for a more consistent use of 'sex' and 'gender'. It considers in turn three influential theoretical frameworks that lend themselves to empirical research. These are: 1) the role of the brain; 2) the role of socialisation; and 3) multi-dimensional gender development. The article ends by suggesting potentially fruitful questions and areas for future research.

    To investigate gender differences in age at onset, psychopathology, and suicidal behavior rates in delusional disorder (DD). We conducted a prospective longitudinal study of 97 patients with DD. Demographic and clinical data at baseline were recorded. Gender differences were investigated by applying analysis of covariance, using age at onset and age at first psychiatric consultation as dependent variables, comorbid depression and gender as between-subject factors, and employment status, social support, and DD types as covariates. Seventy-six percent of the patients were women. The average age at onset was 48.76 ± 12.67 years, mean age at first psychiatric consultation was 54.13 ± 13.67 years, and men were more likely to be employed than women (p = 0.041). Despite the earlier age at onset and at first psychiatric consultation in men, these differences tended to disappear when adjusted for potential confounders. There were no significant gender differences in depressive comorbidity, presence of suicidal ideation and behavior, or compliance rates at follow-up. Our findings could not confirm that male and female DD patients differ in age at onset, age at first psychiatric consultation, or suicidal ideation and behavior, even after controlling for potential confounders.

    Full Text Available Abstract Background Similar to other systems, the endocrine system is affected by aging. Thyroid hormone, the action of which is affected by many factors, has been shown to be associated with longevity. The most useful marker for the assessment of thyroid hormone action is TSH level. Although age and gender are believed to modify the pituitary set point or response to free thyroid hormone concentration, the precise age- and gender-dependent responses to thyroid hormone have yet to be reported. Methods We analyzed the results of 3564 thyroid function tests obtained from patients who received medication at both out- and inpatient clinics of Shinshu University Hospital. Subjects were from among those with thyroid function test results in the normal or mildly abnormal range. Based on a log-linear relationship between the concentrations of FHs and TSH, we established the putative resistance index to assess the relation between serum FH and TSH levels. Results Free thyroid hormone and TSH concentration showed an inverse log-linear relation. In males, there was a negative relationship between the free T3 resistance index and age. In females, although there were no relationships between age and FHs, the indices were positively related to age. Conclusions These findings indicated that there is a gender-specific response to thyroid hormone with aging. Although the TSH level is a useful marker for the assessment of peripheral thyroid hormone action, the values should be interpreted carefully, especially with regard to age- and gender-related differences.

    Differences in problem gambling rates between males and females suggest that associated risk factors vary by gender. Previous combined analyses of male and female gambling may have obscured these distinctions. This study aimed to develop separate risk factor models for gambling problems for males and for females, and identify gender-based similarities and differences. It analysed data from the largest prevalence study in Victoria Australia (N = 15,000). Analyses determined factors differentiating non-problem from at-risk gamblers separately for women and men, then compared genders using interaction terms. Separate multivariate analyses determined significant results when controlling for all others. Variables included demographics, gambling behaviour, gambling motivations, money management, and mental and physical health. Significant predictors of at-risk status amongst female gamblers included: 18-24 years old, not speaking English at home, living in a group household, unemployed or not in the workforce, gambling on private betting, electronic gaming machines (EGMs), scratch tickets or bingo, and gambling for reasons other than social reasons, to win money or for general entertainment. For males, risk factors included: 18-24 years old, not speaking English at home, low education, living in a group household, unemployed or not in the workforce, gambling on EGMs, table games, races, sports or lotteries, and gambling for reasons other than social reasons, to win money or for general entertainment. High risk groups requiring appropriate interventions comprise young adults, especially males; middle-aged female EGM gamblers; non-English speaking populations; frequent EGM, table games, race and sports gamblers; and gamblers motivated by escape.

    This research aims to further current understanding of gender differences in old age mortality. In particular, it assesses the relative importance of health behavior and baseline health conditions in predicting the risk of dying, and how their effects differ between elderly men and women. Data for this research came from a prospective study of a national sample of 2,200 older adults in Japan from 1987 to 1999. Hazard rate models were employed to ascertain the interaction effects involving gender and health behavior (i.e., smoking and drinking) and baseline health status. Gender differences in old age mortality in the Japanese are quite pronounced throughout all of our models. In addition, interaction effects of gender and smoking, functional limitation, and cognitive impairment, indicate that females in Japan suffer more from these risk factors than do their male counterparts. Failure to adjust for population heterogeneity may lead to a significant underestimation of female advantage in survival. The inclusion of health behavior and health status measures only offsets a limited proportion of this gender differential. The increased mortality risk due to smoking, functional limitation, and cognitive impairment among elderly Japanese women suggests that narrowing of gender gap in mortality may be due to not only changes in the levels of these risk factors but also their differential effects on men and women.

    A biokinetic model for strontium in humans is necessary for quantification of internal doses due to strontium radioisotopes. The ICRP-recommended biokinetic model for strontium has limitation for use in a population study, because it is not gender specific and does not cover all age ranges. The extensive Techa River data set on 90Sr in humans (tens of thousands of measurements) is a unique source of data on long-term strontium retention for men and women of all ages at intake. These, as well as published data, were used for evaluation of age- and gender-specific parameters for a new compartment biokinetic model for strontium (Sr-AGe model). The Sr-AGe model has similar structure as the ICRP model for the alkaline earth elements. The following parameters were mainly reevaluated: gastro-intestinal absorption and parameters related to the processes of bone formation and resorption defining calcium and strontium transfers in skeletal compartments. The Sr-AGe model satisfactorily describes available data sets on strontium retention for different kinds of intake (dietary and intravenous) at different ages (0–80 years old) and demonstrates good agreement with data sets for different ethnic groups. The Sr-AGe model can be used for dose assessment in epidemiological studies of general population exposed to ingested strontium radioisotopes.

    It is not known whether there are age- and/or gender-related differences in magnitude of motor-evoked potentials (MEPs) of the submental muscles. Knowledge of this is important in investigations of neurophysiological aspects of swallowing. Forty healthy participants (20 males, 20 females; 20 young [21-35 years], 20 old [53-88 years]) were recruited. Surface electromyography (EMG) electrodes were placed at midline underlying the submental muscle group. Age- and gender-related differences were evaluated in two neurophysiologic measures of swallowing: MEPs stimulated by single-pulse transcranial magnetic stimulation (TMS) over the motor cortex and surface electromyography (sEMG) recorded from the same submental muscle group during non-stimulated swallows. The older participants had larger MEPs during saliva swallowing than the young participants (p = 0.04, d = 0.86). Conversely, the older participants had lower amplitude submental EMG activity during non-stimulated swallows (p = 0.045, d = 0.67). Gender had no significant effect on MEP magnitude and on submental activity during saliva swallowing. There were no effects of age or gender on MEP latencies. These findings suggest deterioration in muscle function with age in a sample of healthy adults presenting with functional swallowing. We speculate that muscular decline is partially ameliorated by increased cortical activity-i.e., increased submental MEPs-so as to preserve swallowing function in healthy older subjects. These findings emphasize the need for different reference points for evaluation of submental MEPs of different age groups.

The identified proteins indicated increases in oxidative and proteolytic proteins and decreases in glycolytic proteins, and antioxidant enzymes. Conclusion Our results provide insights into the gender differences associated to the decline of kidney function in aging. Thus, we show that proteomics can provide valuable information on age-related changes in expression levels of proteins and related modifications. This pilot study is still far from providing candidates for aging-biomarkers. However, we suggest that the analysis of these proteins could suggest mechanisms of cellular aging in kidney, and improve the kidney selection for transplantation.

    Gender is an important determinant of health. We conducted a study to examine hypertension, obesity, hypercholesterolemia, and smoking behavior among adults aged >15 years in urban Indonesia. We compared the prevalence, predicted socioeconomic factors, the gender inequalities, and the contributing factors to the inequalities. Women had a higher risk of obesity and hypercholesterolemia and raised blood pressure in later life (Pgender inequalities in hypertension, obesity, and hypercholesterolemia can be accounted for by disparities in socioeconomic factors between men and women, particularly involvement in paid work. However, the inequalities were also accounted for by different effects of the socioeconomic factors in men and women. Gender is interlinked with socioeconomic and biological factors in determining health. This emphasizes the need of gender responsive policies to control and prevent chronic disease. © 2015 APJPH.

    The effects of aging on human or animal thyroid function are still not well defined. We evaluated some aspects of thyroid function during aging using an animal model (young and old Dutch-Miranda rats). In old rats of both genders, serum thyroxine (T4) decreased but serum thyrotrophin (TSH) remained unaltered, suggesting a disturbance in the pituitary-thyroid feedback mechanism during aging. Serum tri-iodothyronine (T3) only decreased in old males, possibly because female rats are almost twice as efficient in hepatic T4 to T3 deiodination. Thyroidal T4-5'-deiodinase activity did not change much during aging, although it decreased slightly in males. Thyroidal iodothyronine-deiodinase type I mRNA expression but not total thyroidal enzymatic activity were higher in female than in male rats. Thus, ovarian/testicular hormones may modulate the expression and/or the activity of hepatic and thyroidal type I iodothyronine-deiodinase. Thyroperoxidase (TPO) and thyroglobulin (Tg) expression were higher in young male rats than in females. In males, TPO and Tg gene expression decreased with aging, suggesting that androgens might increase their expression. Our results showed that aging induces real changes in rat thyroid gland function and regulation, affecting at least pituitary, thyroid and liver functions. Furthermore, some of these changes were gender related, indicating that gonadal hormones may modulate thyroid gland function and regulation.

    Age and gender classification are two important problems that recently gained popularity in the research community, due to their wide range of applications. Research has shown that both age and gender information are encoded in the face shape and texture, hence the active appearance model (AAM), a statistical model that captures shape and texture variations, has been one of the most widely used feature extraction techniques for the aforementioned problems. However, AAM suffers from some drawbacks, especially when used for classification. This is primarily because principal component analysis (PCA), which is at the core of the model, works in an unsupervised manner, i.e., PCA dimensionality reduction does not take into account how the predictor variables relate to the response (class labels). Rather, it explores only the underlying structure of the predictor variables, thus, it is no surprise if PCA discards valuable parts of the data that represent discriminatory features. Toward this end, we propose a supervised appearance model (sAM) that improves on AAM by replacing PCA with partial least-squares regression. This feature extraction technique is then used for the problems of age and gender classification. Our experiments show that sAM has better predictive power than the conventional AAM.

    Full Text Available The paper elaborates the agegender structure of Croats in Vojvodina and gives insight how old is the Croatian population and does it in general older than population of Vojvodina. Particular attention was given to the period after the Second World War, e.g. on the second half of 20th and at the beginning of 21st century. The main task of the paper was the identification of tendencies in age structure of Croats. Statistical methods and mathematics proceeding are used to compare different parameters of age structure (e.g. middle age, index of ageing etc. The paper proves that Croats are one of the oldest ethnic groups among the population of Vojvodina province. The results of the study will enhance the knowledge about demographic characteristics of Croats in Vojvodina and therefore might be useful for further research in the field.

    The abdominal aorta (AA) is predisposed to development of abdominal aneurysms (AAA), a focal dilatation with fatal consequences if left untreated. The blood flow patterns is thought to play an important role in the development of AAA. The purpose of this work is to investigate the blood flow patterns within a group of healthy volunteers (six females, eight males) aged 23 to 76 years to identify changes and differences related to age and gender. The healthy volunteers were categorized by gender (male/female) and age (below/above 35 years). Subject-specific flow and geometry data were acquired using the research interface on a Profocus ultrasound scanner (B-K Medical, Herlev, Denmark; segmentation of 3D magnetic resonance angiography (Magnetom Trio, Siemens Healthcare, Erlangen, Germany). The largest average diameter was among the elderly males (19.7 (+/- 1.33) mm) and smallest among the young females (12.4 (+/- 0.605) mm). The highest peak systolic velocity was in the young female group (1.02 (+/- 0.336) m/s) and lowest in the elderly male group (0.836 (+/- 0.127) m/s). A geometrical change with age was observed as the AA becomes more bended with age. This also affects the blood flow velocity patterns, which are markedly different from young to elderly. Thus, changes in blood flow patterns in the AA related to age and gender are observed. Further investigations are needed to determine the relation between changes in blood flow patterns and AAA development.

    As biometrics-based identification and identity authentication become increasingly widespread in their deployment, it becomes correspondingly important to consider more carefully issues relating to reliability, usability and inclusion. One factor which is particularly important in this context is that of the relationship between the nature of the measurements extracted from a particular biometric modality and the age of the sample donor, and the effect which age has on physiological and behavioural characteristics invoked in a biometric transaction.

    Full Text Available BACKGROUND: Intracerebral hemorrhage (ICH is a common and devastating form of cerebrovascular disease. In ICH, gender differences in outcomes remain relatively understudied but have been examined in other neurological emergencies. Further, a potential effect of age and gender on outcomes after ICH has not been explored. This study was designed to test the hypothesis that age and gender interact to modify neurological outcomes after ICH. METHODS: Adult patients admitted with spontaneous primary supratentorial ICH from July 2007 through April 2010 were assessed via retrospective analysis of an existing stroke database at Duke University. Univariate analysis of collected variables was used to compare gender and outcome. Unfavorable outcome was defined as discharge to hospice or death. Using multivariate regression, the combined effect of age and gender on outcome after ICH was analyzed. RESULTS: In this study population, women were younger (61.1+14.5 versus 65.8+17.3 years, p=0.03 and more likely to have a history of substance abuse (35% versus 8.9%, p<0.0001 compared to men. Multivariable models demonstrated that advancing age had a greater effect on predicting discharge outcome in women compared to men (p=0.02. For younger patients, female sex was protective; however, at ages greater than 60 years, female sex was a risk factor for discharge to hospice or death. CONCLUSION: While independently associated with discharge to hospice or death after ICH, the interaction effect between gender and age demonstrated significantly stronger correlation with early outcome after ICH in a single center cohort. Prospective study is required to verify these findings.

    The escalating use of khat (Catha edulis) in East Africa and Arabia is a major concern for public health. Yet little is known about the impact of khat on behaviour. To that end, there has been no study in the region to assess the extent to which dependence syndrome is associated with khat use in this population. We examined in this study was psychometric properties of the Severity of Dependence Scale-Khat (SDS-khat), gender differences in patterns of khat use and dependence, and the extent to which age moderated the link between gender and khat dependence. Two-hundred and ninety-two khat chewers recruited in two Yemeni cities completed face-to-face interviews asking about demographics and patterns of khat use. Validity of SDS-khat was examined by the principle component analysis and reliability of the scale was tested by the Cronbach's alpha. A series of chi-square tests and analysis of variances (ANOVAs) were conducted to examine gender differences in khat use variables. The results indicated that the mean age of khat chewers was 30.52 years (95% CI: 29.34, 31.70) years, and 52% of them were males. The SDS-khat was found to have two factors with moderate reliability. This pattern was consistent when the analysis was conducted in the entire sample and in each gender. Male khat chewers reported more symptoms related to khat dependence than female chewers. A significant gender by age interaction in SDS-khat levels (p =0.013) revealed a positive association between age and khat dependence in women only. These results provide initial support for the use of SDS-khat in the assessment of khat dependence in Yemen. Gender differences in khat use patterns and dependence observed in this study call the need for more studies carefully examining the role of gender in khat research. PMID:25064835

    Cognitive skills decline with age. Our ability to keep oriented in our surrounding environment was demonstrated to be influenced by factors like age and gender. Introduction of virtual reality based tasks improved assessment of spatial memory in humans. In this study, spatial orientation was assessed in a virtual memory task in order to determine the effect of aging and gender on navigational skills. Subjects from 45 to 74 years of age were organized in three groups (45-54, 55-64, 65-74 years old). Two levels of difficulty were considered. Results showed that males outperformed females in 65-74 years-old group. In addition to this, females showed a more noticeable poor performance in spatial memory than males, since memory differences appeared between all age groups. On the other hand, 65-74 year-old males showed an impaired performance in comparison with 45-54 year-old group. These results support that spatial memory becomes less accurate as we age and gender is an important factor influencing spatial orientation skills.

    2012-02-01

    Full Text Available The aim of this study was to determine the prevalence of suicidal ideation in patients who were tested for HIV-infection and whether along with their HIV status, age and gender influenced their risk for suicidal ideation. The sample consisted of 189 patients who attended a voluntary HIV counseling and testing clinic (VCT at a general state hospital in Durban, South Africa. Their mean age at baseline was 34.2 years, with an age range of between 16–79 years. Seropositivity, age and gender were significantly associated with suicidal ideation. The majority of these patients were in the younger age group, and young males had a 1.8 times higher risk for suicidal ideation than females. Although risk factors for seropositive-related suicidal ideation can be complex and multi-factorial, this study identified a young age and male gender as important high risk factors in the sample studied. It is recommended that all, but especially young male HIV-infected patients seen at a VCT clinic be screened for suicidal ideation and that early intervention to prevent subsequent suicides or suicidal attempts be included in pre- and post-test HIV counseling.

    Economists and other social scientists typically rely on gender differences in the family-career balance, discrimination, and ability to explain gender gaps in wages and in the prospect for advancement. A new explanation that has recently surfaced in the economics literature is that men are more...... competitively inclined than women, and having a successful career requires competitiveness. A natural question revolves around the underlying determinants of these documented competitive differences: are women simply born less competitive, or do they become so through the process of socialization? To shed light...... on this issue, we compare the competitiveness of children in matrilineal and patriarchal societies to show that the difference starts around puberty. Moreover, most of the changes during this period of life are within the patriarchal society, in which boys become more competitive with age while girls become...

    Full Text Available Abstract Background Research results from large, national population-based studies investigating gender differences in weight dissatisfaction and disordered eating across the adult life span are still limited. Gender is a significant factor in relation to weight dissatisfaction and disordered eating. However, the reasons for gender differences in these conditions are still poorly understood. The aim of this study was to examine gender differences in weight dissatisfaction and disordered eating in the general Swiss adult population and to identify gender-specific risk factors. Methods The study population consisted of 18156 Swiss adults who completed the population-based Swiss Health Survey 2007. Self-reported weight dissatisfaction, disordered eating and associated risk factors were assessed. In order to examine whether determinants of weight dissatisfaction and disordered eating (dieting to lose weight, binge eating, and irregular eating differ in men and women, multivariate logistic regressions were applied separately for women and men. Results Although more men than women were overweight, more women than men reported weight dissatisfaction. Weight category, smoking status, education, and physical activity were significantly associated with weight dissatisfaction in men and women. In women, nationality and age were also significant factors. Gender-specific risk factors such as physical activity or weight category were identified for specific disordered eating behaviours. Conclusions The results suggest that gender specific associations between predictors and disordered eating behaviour should be considered in the development of effective prevention programs against disordered eating.

    Full Text Available Urinary tract infections (UTIs are among the most frequent community-acquired infections worldwide. Escherichia coli is the most common UTI pathogen although underlying host factors such as patients’ age and gender may influence prevalence of causative agents. In this study, 61 273 consecutive urine samples received over a 22-month period from outpatients clinics of an urban area of north Italy underwent microbiological culture with subsequent bacterial identification and antimicrobial susceptibility testing of positive samples. A total of 13 820 uropathogens were isolated and their prevalence analyzed according to patient’s gender and age group. Overall Escherichia coli accounted for 67.6% of all isolates, followed by Klebsiella pneumoniae (8.8%, Enterococcus faecalis (6.3%, Proteus mirabilis (5.2%, and Pseudomonas aeruginosa (2.5%. Data stratification according to both age and gender showed E. coli isolation rates to be lower in both males aged ≥60 years (52.2%, E. faecalis and P. aeruginosa being more prevalent in this group (11.6% and 7.8%, resp., as well as in those aged ≤14 years (51.3% in whom P. mirabilis prevalence was found to be as high as 21.2%. Streptococcus agalactiae overall prevalence was found to be 2.3% although it was shown to occur most frequently in women aged between 15 and 59 years (4.1%. Susceptibility of E. coli to oral antimicrobial agents was demonstrated to be as follows: fosfomycin (72.9%, trimethoprim/sulfamethoxazole (72.9%, ciprofloxacin (76.8%, ampicillin (48.0%, and amoxicillin/clavulanate (77.5%. In conclusion, both patients’ age and gender are significant factors in determining UTIs etiology; they can increase accuracy in defining the causative uropathogen as well as providing useful guidance to empiric treatment.

  2. Risk of advanced colorectal neoplasia according to age and gender.

    Frank T Kolligs

    Full Text Available BACKGROUND: Colorectal cancer (CRC is one of the leading causes of cancer related morbidity and death. Despite the fact that the mean age at diagnosis of CRC is lower in men, screening by colonoscopy or fecal occult blood test (FOBT is initiated at same age in both genders. The prevalence of the common CRC precursor lesion, advanced adenoma, is well documented only in the screening population. The purpose of this study was to assess the risk of advanced adenoma at ages below screening age. METHODS AND FINDINGS: We analyzed data from a census of 625,918 outpatient colonoscopies performed in adults in Bavaria between 2006 and 2008. A logistic regression model to determine gender- and age-specific risk of advanced neoplasia was developed. Advanced neoplasia was found in 16,740 women (4.6% and 22,684 men (8.6%. Male sex was associated with an overall increased risk of advanced neoplasia (odds ratio 1.95; 95% confidence interval, CI, 1.91 to 2.00. At any age and in any indication group, more colonoscopies were needed in women than in men to detect advanced adenoma or cancer. At age 75 14.8 (95% CI, 14.4-15.2 screening, 18.2 (95% CI, 17.7-18.7 diagnostic, and 7.9 (95% CI, 7.6-8.2 colonoscopies to follow up on a positive FOBT (FOBT colonoscopies were needed to find advanced adenoma in women. At age 50 39.0 (95% CI, 38.0-40.0 diagnostic, and 16.3 (95% CI, 15.7-16.9 FOBT colonoscopies were needed. Comparable numbers were reached 20 and 10 years earlier in men than in women, respectively. CONCLUSIONS: At any age and independent of the indication for colonoscopy, men are at higher risk of having advanced neoplasia diagnosed upon colonoscopy than women. This suggests that starting screening earlier in life in men than in women might result in a relevant increase in the detection of asymptomatic preneoplastic and neoplastic colonic lesions.

    Although early childhood is a period of rapid neurocognitive development, few studies have assessed neuropsychological functioning in various cognitive domains in young typically developing children. Also, results regarding its association with gender and intelligence are mixed. In 853 typically developing children aged 6 to 10 years old, the association of gender, age, and intelligence with neuropsychological functioning in the domains of attention, executive functioning, language, memory, sensorimotor functioning, and visuospatial processing was explored. Clear positive associations with age were observed. In addition, gender differences were found and showed that girls generally outperformed boys, with the exception of visuospatial tasks. Furthermore, IQ was positively associated with neuropsychological functioning, which was strongest in visuospatial tasks. Performance in different neuropsychological domains was associated with age, gender, and intelligence in young typically developing children, and these factors should be taken into account when assessing neuropsychological functioning in clinical or research settings.

    2017-04-01

    Among the causes of fatalities during floods, the loss of stability is an aspect which has been usually investigated with conceptual models and laboratory experiments. The human body geometry has been often simplified to derive mechanical equilibrium conditions for toppling and sliding due to weight and hydrodynamic actions. Experimental activity produced water depth versus velocity diagrams showing the critical conditions for people partly immersed in floodwaters, whose scatter reflects the large variability of tested subjects (i.e. children, men and women with different physical characteristics). Nevertheless, the proposed hazard criteria based on the product number HV are not capable of distinguishing between different subjects. A dimensionless approach with a limited number of parameters and 3D numerical simulations highlight the significance of subject height and quantify the drag forces different subjects are able to withstand. From the mechanical point of view, this approach significantly reduces the experimental scatter. Differences in subjects' height are already an evidence of gender differences; however, many other parameters such as age and skeletal muscle mass may play a significant role in individual responses to floodwater actions, which can be responsible of the residual unexplained variance. In this work, a sensitivity analysis of critical instability conditions with respect to gender/age-related parameters is carried out and results and implications for flood risk management are discussed.

    Full Text Available The article discusses the impact of gender asymmetry on the socio-economic development of the country. Authors detected factors that determine with high level of the probability social development of the society. Econometric relationship between the level of GDP per capita in comparative prices and the socio-cultural and gender factors are developed and estimated. The analysis showed that the level of individualism, indulgence, economic participation, and political empowerment of women in the society have direct linear correlation with GDP per capita. Power distance has opposite inverse correlation with the level of GDP. Application of regression analysis gave the possibility to divide all countries into 9 clusters with similar features. Two-dimensional matrix included GDP per capita and coefficient of implementation of a country gender and sociocultural potential. The recommendations for stimulating economic growth by smoothing gender gaps are proposed.

    Full Text Available Skin ageing and gender influences on the scalp have been seldom studied. We revisited the changes in the interfollicular scalp. The study was performed on a population of 650 volunteers (300 women and 350 men for over 7 years. Three age groups were selected in both genders, namely, subjects aged 20–35, 50–60, and 60–70 years. The hair status was further considered according to nonalopecic and alopecic patterns and severity (discrete, moderate, and severe. Biopsies from the parietal area were processed for immunohistochemistry. Stromal cells were distinguished according to the presence of vimentin, Factor XIIIa, CD117, and versican. Blood and lymphatic vessels were highlighted by Ulex europaeus agglutinin-1 and human podoplanin immunoreactivities, respectively. Actinic elastosis was identified by the lysozyme coating of elastic fibres. The epidermis was explored using the CD44 variant 3 and Ki67 immunolabellings. Biplot analyses were performed. Immunohistochemistry revealed a prominent gender effect in young adults. Both Factor XIIIa+ dermal dendrocytes and the microvasculature size decreased with scalp ageing. Alopecia changes mimicked stress-induced premature senescence.

    This study focused on age-related changes in visual short-term memory using visual stimuli that did not allow verbal encoding. Experiment 1 examined the effects of age and the length of the stimulus presentation period on visual short-term memory function. Experiment 2 examined the effects of age, gender, and the length of the stimulus presentation period on visual short-term memory function. The worst memory performance and the largest performance difference between the age groups were observed in the shortest stimulus presentation period conditions. The performance difference between the age groups became smaller as the stimulus presentation period became longer; however, it did not completely disappear. Although gender did not have a significant effect on d' regardless of the presentation period in the young group, a significant gender-based difference was observed for stimulus presentation periods of 500 ms and 1,000 ms in the older group. This study indicates that the decline in visual short-term memory observed in the older group is due to the interaction of several factors.

    As populations age, psychological distress in late life will become of increasing public health and social importance. This study seeks to bridge the gap in information that exists about psychological distress in late life, by exploring the prevalence of psychological distress among a very large sample of older adults to determine the impact of age and gender, and the modifying effect of these factors on the associations between measures of psychological distress and sociodemographic and comorbid conditions. We analyzed self-reported data from 236,508 men and women in the New South Wales 45 and Up Study, to determine the impact of age and gender, and the modifying effects of these factors on associations between psychological distress and sociodemographic and comorbid conditions. Higher education, married status, and higher income were associated with lower risk of psychological distress. Although overall prevalence of psychological distress is lower at older ages, this increases after age 80, and is particularly associated with physical disabilities. Some older people (such as those requiring help because of disability and those with multiple comorbid health conditions) are at increased risk of psychological distress. These findings have implications for both healthcare providers and policy-makers in identifying and responding to the needs of older people in our aging society.

  15. Age, education, and the gender gap in the sense of control.

    High sense of control is related to benefits in many aspects of life, and education is known to be strongly related to sense of control. In this article we explore why women tend to feel a lower sense of control than men, and why the sense of control tends to be lower among the elderly than among younger people. In particular we explore the role played by education in explaining age- and gender differences in sense of control. The analysis is based on data from the first wave of the Norwegian NorLAG study, with a representative sample of adults aged 40-79 in 30 municipalities. We find that education accounts for some of the age and gender differences in sense of control, but the mediating effects of education are rather modest. We find an increasing gender gap in sense of control with age, and this increasing gap is completely explained by differences in education. Gender differences in sense of control is explained completely by four factors, which are related to resources and power; physical health, education, living with a partner, and leadership experience. Age differences in sense of control are only partially explained. Education, physical health and employment status cuts the age effect on sense of control to half. The effect of education on sense of control is partly mediated through what we suggest are tangible benefits of education, namely health, employment, and leadership experience. Education also influences individuals through socialization mechanisms. We view agentive orientation as a psychological benefit of education, and measure this characteristic with Bem's (1981) sex-role scale on masculinity. Agentive orientation completely explains the remaining effect of education on sense of control.

    Early adolescence (ages 10-14) is a period of increased expectations for boys and girls to adhere to socially constructed and often stereotypical norms that perpetuate gender inequalities. The endorsement of such gender norms is closely linked to poor adolescent sexual and reproductive and other health-related outcomes yet little is known about the factors that influence young adolescents' personal gender attitudes. To explore factors that shape gender attitudes in early adolescence across different cultural settings globally. A mixed-methods systematic review was conducted of the peer-reviewed literature in 12 databases from 1984-2014. Four reviewers screened the titles and abstracts of articles and reviewed full text articles in duplicate. Data extraction and quality assessments were conducted using standardized templates by study design. Thematic analysis was used to synthesize quantitative and qualitative data organized by the social-ecological framework (individual, interpersonal and community/societal-level factors influencing gender attitudes). Eighty-two studies (46 quantitative, 31 qualitative, 5 mixed-methods) spanning 29 countries were included. Ninety percent of studies were from North America or Western Europe. The review findings indicate that young adolescents, across cultural settings, commonly express stereotypical or inequitable gender attitudes, and such attitudes appear to vary by individual sociodemographic characteristics (sex, race/ethnicity and immigration, social class, and age). Findings highlight that interpersonal influences (family and peers) are central influences on young adolescents' construction of gender attitudes, and these gender socialization processes differ for boys and girls. The role of community factors (e.g. media) is less clear though there is some evidence that schools may reinforce stereotypical gender attitudes among young adolescents.

    Surface Electromyography (sEMG) is a technology to measure the bio-potentials across the muscles. The true prospective of this technology is yet to be explored. In this paper, a simple and economic construction of a sEMG sensor is proposed. These sensors are used to determine the differences in the Electromyography (EMG) signal patterns of different individuals. Signals of several volunteers from different age groups, gender and individual having paralysis have been obtained. The sEMG data acquisition is done using the soundcard of a computer, hence reducing the need of additional hardware. Finally, the data is used to analyse the relationship between electromyography and factors like age, gender and health condition i.e. paralysis.

    The purpose of this study is to examine the impact that gender and age differences have on the communication media selection within the context of small and medium tourism enterprises (SMEs). Media Richness Theory (MRT) was used to assess media preferences in the firms. Using a mail questionnaire, data from 78 firms were collected on seven popular media in use. Historical data of the firms, media characteristics, and other firm-specific factors were included in the analysis. The results indicated that there are substantial gender and age differences in term of communication media selection. This is consistent with MRT and highlights the importance of choosing the appropriate media in SMEs, according with the employee's behaviors, in order to achieve better outcomes and to smooth the path towards good performance in the future.

    Full Text Available In very old age, emotional states become the most important reasonto maintain life satisfaction. In this study we examined the role of positive and negative emotions on the judgment of life satisfaction in advanced old age and the age and gender differences in a sample of 400 elderly people of Salamanca, aged between 75 and 104. The results show a higher frequency of positive emotions than negative, with the most frequent of the former being attentive,active and strong, and the less frequent ones being excited and inspired. Among the more frequent negative emotions are feeling jittery, nervous and alert, and the less frequent ones are feeling guilty, hostile and ashamed. In addition, there are differences in terms of both age (people aged between 75 and 84 are more active, enthusiastic and inspired and gender (very old women are more jittery, nervous, proud, afraid, scared and upset. Moreover, multiple regression analysis showed that remaining lively, happy, interested and alert to events is essential for maintaining the life satisfaction of people aged over 75. These results confirm that positive emotions are a potential resource for psychological esilience in advanced old age.

    Full Text Available The purpose of this study was to identify gender differences in risk factors of fall accidents among older people, and whether these factors differ between single and recurrent fallers. A total of 4,426 individuals aged ≥65 years from two large-scale health surveys provided data. Logistic regression analyses were used to identify risk factors and to determine the risk model for falling and recurrent falling in men and women separately. Three major risk factors for falling regardless of gender or fall history are fear of falling, limitations in activities of daily living (ADL, and age ≥75 years. Fear of falling remains one of the common modifiable risk factors. Among those without a fall history, the use of sedatives or tranquilizers increases the risk of falling. Regarding gender differences, ADL limitations and fear of falling appear to be stronger fall risk factors for men than for women. Among women, alcohol use and educational level are significant risk factors for falling, while loneliness is associated with recurrent falling. Men with fear of falling or ADL limitations are at higher risk to have a recurrent fall accident than women with these conditions. Having a visual impairment or living with someone is associated with recurrent falling among men. Our findings emphasize the importance of multifactorial fall interventions, taking into account a variety of subgroup characteristics such as gender and fall history.

    The purpose of the study was to investigate the relationships among gender, age, and self-image of adolescents attending three secondary schools in Jamaica. The relatively few studies that have been done regarding self-perceptions of these youth are not only dated but have utilized a unidimensional conceptualization of the self. The Offer Self-Image Questionnaire which employs a multidimensional construct of the self was administered to a sample of 174 Jamaican adolescents ranging in age from 14 to 18 years (M = 15.90 years, SD = 1.21). Results revealed statistically significant effects for both gender and age. Gender was found to be significant on one self-image dimension: Morals, while age differences were evident on six dimensions: Social Relationships, Morals, Sexual Attitudes, Mastery of the External World, Vocational and Educational Goals, and Emotional Health. The results in some instances were contrary to those of past research. Discussion focused on cultural socialization and other factors affecting youth in Jamaican society.

    The Levels of Emotional Awareness Scale (LEAS) developed by Lane et al. (1990) measures the ability of a subject to discriminate his or her own emotional state and that of others. The scale is based on a cognitive-developmental model in which emotional awareness increases in a similar fashion to intellectual functions. Because studies performed using North American and German populations have demonstrated an effect of age, gender, and level of education on the ability to differentiate emotional states, our study attempts to evaluate whether these factors have the same effects in a general French population. 750 volunteers (506 female, 244 male), who were recruited from three regions of France (Lille, Montpellier, Paris), completed the LEAS. The sample was divided into five age groups and three education levels. The results of the LEAS scores for self and others and the total score showed a difference in the level of emotional awareness for different age groups, by gender and education level. A higher emotional level was observed for younger age groups, suggesting that emotional awareness depends on the cultural context and generational societal teachings. Additionally, the level of emotional awareness was higher in women than in men and lower in individuals with less education. This result might be explained by an educational bias linked to gender and higher education whereby expressive ability is reinforced. In addition, given the high degree of variability in previously observed scores in the French population, we propose a standard based on our French sample.

    The aim of the study is to evaluate corneal asphericity in three diameters of 5, 6, and 7 mm, and to assess the effect of age, refractive error, and gender on asphericity. The study included 500 healthy subjects with a mean ± SD age of 29.51 ± 11.53 years. All analyses were based on the right eyes of the patients. Topographic data were analyzed using Oculus Keratograph 4. Mean ± SD corneal asphericity values of the study population in 5, 6, and 7 mm diameters were -0.21 ± 0.11, -0.24 ± 0.10, and -0.27 ± 0.11, respectively. The anterior corneal surface asphericity showed no correlation with either age, gender, or refractive error. The corneal asphericity shows a tendency for an increase with diameter and asphericity does not have a significant correlation with any factors of age, gender, and refractive error.

    Full Text Available Aims: To examine the variation in risk factors and hospitalization costs among four elderly dementia cohorts by race and gender. Materials and Methods: The 2008 Tennessee Hospital Discharged database was examined. The prevalence, risk factors and cost of inpatient care of dementia were examined for individuals aged 65 years and above, across the four race gender cohorts - white males (WM, black males (BM, white females (WF, and black females (BF. Results: 3.6% of patients hospitalized in 2008 had dementia. Dementia was higher among females than males, and higher among blacks than whites. Further, BF had higher prevalence of dementia than WF; similarly, BM had a higher prevalence of dementia than WM. Overall, six risk factors were associated with dementia for the entire sample including HTN, DM, CKD, CHF, COPD, and stroke. These risk factors varied slightly in predicting dementia by race and gender. Hospital costs were 14% higher among dementia patients compared to non-dementia patients. Conclusions: There exist significant race and gender disparities in prevalence of dementia. A greater degree of co-morbidity, increased duration of hospital stay, and more frequent hospitalizations, may result in a higher cost of inpatient dementia care. Aggressive management of risk factors may subsequently reduce stroke and cost of dementia care, especially in the black population. Race and gender dependent milestones for management of these risk factors should be considered.

    Controlling blood pressure is a key step in reducing cardiovascular mortality in older adults. Gender differences in patients' attitudes after disease diagnosis and their management of the disease have been identified. However, it is unclear whether gender differences exist in hypertension management among older adults. We hypothesized that gender differences would exist among factors associated with hypertension diagnosis and control among community-dwelling, older adults. This cross-sectional study analyzed data from 653 Koreans aged ≥60 years who participated in the Korean Social Life, Health, and Aging Project. Multiple logistic regression was used to compare several variables between undiagnosed and diagnosed hypertension, and between uncontrolled and controlled hypertension. Diabetes was more prevalent in men and women who had uncontrolled hypertension than those with controlled hypertension or undiagnosed hypertension. High body mass index was significantly associated with uncontrolled hypertension only in men. Multiple logistic regression analysis indicated that in women, awareness of one's blood pressure level (odds ratio [OR], 2.86; p=0.003) and the number of blood pressure checkups over the previous year (OR, 1.06; p=0.011) might influence the likelihood of being diagnosed with hypertension. More highly educated women were more likely to have controlled hypertension than non-educated women (OR, 5.23; p=0.013). This study suggests that gender differences exist among factors associated with hypertension diagnosis and control in the study population of community-dwelling, older adults. Education-based health promotion strategies for hypertension control might be more effective in elderly women than in elderly men. Gender-specific approaches may be required to effectively control hypertension among older adults.

    Ecological factors modulate animal immunocompetence and potentially shape the evolution of their immune systems. Not only environmental parameters impact on immunocompetence: Aging is one major cause of variability of immunocompetence between individuals, and sex-specific levels of immunocompetence have also been frequently described. Moreover, a growing core of data put in light that vertically transmitted symbionts can dramatically modulate the immunocompetence of their hosts. In this study, we addressed the influence of gender, age and the feminising endosymbiont Wolbachia ( wVulC) on variations in haemocyte density, total PO activity and bacterial load in the haemolymph of the terrestrial isopod Armadillidium vulgare. This host-symbiont system is of particular interest to address this question since: (1) wVulC was previously shown as immunosuppressive in middle-aged females and (2) wVulC influences sex determination. We show that age, gender and Wolbachia modulate together immune parameters in A. vulgare. However, wVulC, which interacts with aging, appears to be the prominent factor interfering with both PO activity and haemocyte density. This interference with immune parameters is not the only aspect of wVulC virulence on its host, as reproduction and survival are also altered.

    In this paper we suggest that older adults undergo a misalignment between societal age norms and personal lived experience, and attempt reconciliation through discursive strategies: They rewrite how they frame chronological age as well as their subjective relations to it. Using a sample of 4041 midlife and older adults from the 2004-2006 wave of the National Survey of Midlife Development in the United States (MIDUS II), we explore associations of age and gender with subjective age and at what age respondents felt people enter later life. Our results confirm that as men and women age, they push up the age at which they think people enter later life, and slow down subjective aging (there is a growing gap between subjective and chronological age). Relations between a person's age and at what age they think people enter later life were stronger for men than for women. For every year they get older get older, men push up when they think people enter later life by 0.24years, women by 0.16years. Age norms surrounding the transition to later life may be more prominent for men than for women, and the difference in their tendencies to push up when they mark entry into later life may be a reflection of this greater prominence.

    2016-08-01

    This paper examines gender differentials in survival amongst older people (50+ years) in the Nairobi slums and to the best of our knowledge is the first study of its kind in an urban African setting. The results provide evidence contrary to the expected paradox of poorer self-rated health yet better survival amongst older women. Older women in the Nairobi slums have poorer self-rated health and poorer circumstances across other factors, including disability and socio-economic status. Further, older women in the slums do not have better survival. The conventional female advantage in mortality only becomes apparent after accounting for the cumulative influence of individual characteristics, social networks, health and socio-economic status, suggesting the female advantage in unadjusted old-age mortality does not apply to contexts where women experience significant disadvantage across multiple life domains. This highlights the urgent need to redress the support, status and opportunities available for women across the life course in contexts such as the Nairobi slums. In addition, a greater number of factors differentiate mortality risk amongst men than amongst women, suggesting inequality amongst slum dwelling older men and highlighting the need for gender sensitive interventions which account for the particular needs of both genders in old age.

    We have analyzed health and physiological aging parameters in male and female Atlantic cod, Gadus morhua, captured in Kattegat, Skagerrak and in Öresund. Gender differences were clearly evident in a number of variables. Males had longer liver telomeres and higher catalase activities than females, while females had higher superoxide dismutase activity, liver somatic index and condition factor. Effects of age were found for males where levels of the antioxidant glutathione and telomere length declined with age, indicating physiological aging. Liver somatic index increased and percentage oxidized glutathione decreased with age. Between-site comparisons of males show that percentage oxidized glutathione and catalase were lowest in Kattegat, whereas protein carbonyls and condition factor were higher in Skagerrak. Females, on the other hand, showed no differences between sites or indications of somatic aging or age-related effects in egg quality, indicating that older and larger female cod are healthy and show no changes in eggs with age. In contrast, males showed indications of physiological aging and lower condition than females. The results emphasize the importance of conserving old mature fish, in particular high egg-productive females, when managing fisheries.

    2014-02-01

    This study compared message-framing effects on physical activity (PA) across age and gender groups. Participants included 111 younger and 100 older adults (68% were women), randomly assigned to read gain-framed or loss-framed PA messages in promotion pamphlets, and who wore accelerometers for the following 14 days. Using regression analyses controlling for demographic and health factors, we found significant age-by-gender-by-framing interactions predicting self-report (B = -4.39, p = .01) and accelerometer-assessed PA (B = -2.44, p = .02) during the follow-up period. Gain-framed messages were more effective than loss-framed messages in promoting PA behaviors only among older men. We speculated that the age-related positivity effect, as well as the age and gender differences in issue involvement, explained the group differences in framing. In addition, more time availability and higher self-efficacy among older men might have contributed to the results.

    Five factors have been shown to influence the 20-fold variation of fetal hemoglobin (Hb F) levels in sickle cell anemia (SS): age, sex, the alpha-globin gene number, beta-globin haplotypes, and an X-linked locus that regulates the production of Hb F-containing erythrocytes (F cells), ie, the F-cell production (FCP) locus. To determine the relative importance of these factors, we studied 257 Jamaican SS subjects from a Cohort group identified by newborn screening and from a Sib Pair study. Linear regression analyses showed that each variable, when analyzed alone, had a significant association with Hb F levels (P haplotypes, alpha-globin genes, and age accounted for less than 10% of the variation. The association between the beta-globin haplotypes and Hb F levels becomes apparent if the influence of the FCP locus is removed by analyzing only individuals with the same FCP phenotype. Thus, the FCP locus is the most important factor identified to date in determining Hb F levels. The variation within each FCP phenotype is modulated by factors associated with the three common beta-globin haplotypes and other as yet unidentified factor(s).

    Intelligent digital signage systems transmit customized advertising and information by analyzing users and customers, unlike existing system that presented advertising in the form of broadcast without regard to type of customers. Currently, development of intelligent digital signage system has been pushed forward vigorously. In this study, we designed a system capable of analyzing gender and age of customers based on image obtained from camera, although there are many different methods for analyzing customers. We conducted age and gender recognition experiments using public database. The age/gender recognition experiments were performed through histogram matching method by extracting Local binary patterns (LBP) features after facial area on input image was normalized. The results of experiment showed that gender recognition rate was as high as approximately 97% on average. Age recognition was conducted based on categorization into 5 age classes. Age recognition rates for women and men were about 67% and 68%, respectively when that conducted separately for different gender.

    Full Text Available The research uses both qualitative and quantitative methodologies employing multiple sources of data collection. The data collection primarily used a questionnaire survey of primary schools in two English Local Authorities. The qualitative evidence of the teacher sample was through individual semi-structured interviews and a focus group interview of Local Authorities officers. There is an evidence trail which examines academic papers, HMI, QCA, Ofsted and DfES reports. The main findings from these reports indicate that teachers were becoming familiar with the use of computers. They understood the skills involved in using computers but were still uncertain as to a suitable pedagogy which made them lack confidence when using ICT in the classroom. Teachers’ major difficulty is finding time to keep pace or develop their ICT skills. The reports have a generic view of teachers, with no further analysis of gender, age or experience phenomena. The analysis of these variables concludes that teacher subject knowledge formed through teaching experience of the subject, informs teachers when computers aid teaching and learning.

    Patients with an acute Achilles tendon rupture (ATR) take a long time to heal, have a high incidence of deep vein thrombosis (DVT) and widely variable functional outcomes. This variation in outcome may be explained by a lack of knowledge of adverse factors, and a subsequent shortage of appropriate interventions. A total of 111 patients (95 men, 16 women; mean age 40.3, standard deviation 8.4) with an acute total ATR were prospectively assessed. At one year post-operatively a uniform outcome score, Achilles Combined Outcome Score (ACOS), was obtained by combining three validated, independent, outcome measures: Achilles tendon Total Rupture Score, heel-rise height test, and limb symmetry heel-rise height. Predictors of ACOS included treatment; gender; age; smoking; body mass index; time to surgery; physical activity level pre- and post-injury; symptoms; quality of life and incidence of DVT. There were three independent variables that correlated significantly with the dichotomised outcome score (ACOS), while there was no correlation with other factors. An age of less than 40 years old was the strongest independent predictor of a good outcome one year after ATR (odds ratio (OR) 0.20, 95% confidence interval (CI) 0.08 to 0.51), followed by female gender (OR) 4.18, 95% CI 1.01 to 17.24). Notably, patients who did not have a DVT while immobilised post-operatively had a better outcome (OR 0.31, 95% CI 0.12 to 0.80). Over the age of 40 years, male gender and having a DVT while immobilised are independent negative predictors of outcome in patients with an acute ATR.

    There are many studies that evaluate the effects of age, gender, and crash types on crash related injury severity. However, few studies investigate the effects of those crash factors on the crash related health care costs for drivers that are transported to hospital. The purpose of this study is to examine the relationships between drivers' age, gender, and the crash types, as well as other crash characteristics (e.g., not wearing a seatbelt, weather condition, and fatigued driving), on the crash related health care costs. The South Carolina Crash Outcome Data Evaluation System (SC CODES) from 2005 to 2007 was used to construct six separate hierarchical linear regression models based on drivers' age and gender. The results suggest that older drivers have higher health care costs than younger drivers and male drivers tend to have higher health care costs than female drivers in the same age group. Overall, single vehicle crashes had the highest health care costs for all drivers. For males older than 64-years old sideswipe crashes are as costly as single vehicle crashes. In general, not wearing a seatbelt, airbag deployment, and speeding were found to be associated with higher health care costs. Distraction-related crashes are more likely to be associated with lower health care costs in most cases. Furthermore this study highlights the value of considering drivers in subgroups, as some factors have different effects on health care costs in different driver groups. Developing an understanding of longer term outcomes of crashes and their characteristics can lead to improvements in vehicle technology, educational materials, and interventions to reduce crash-related health care costs.

  6. Gender- and age-dependent gamma-secretase activity in mouse brain and its implication in sporadic Alzheimer disease.

    Directory of Open Access Journals (Sweden)

    Lisa Placanica

    Full Text Available Alzheimer disease (AD is an age-related disorder. Aging and female gender are two important risk factors associated with sporadic AD. However, the mechanism by which aging and gender contribute to the pathogenesis of sporadic AD is unclear. It is well known that genetic mutations in gamma-secretase result in rare forms of early onset AD due to the aberrant production of Abeta42 peptides, which are the major constituents of senile plaques. However, the effect of age and gender on gamma-secretase has not been fully investigated. Here, using normal wild-type mice, we show mouse brain gamma-secretase exhibits gender- and age-dependent activity. Both male and female mice exhibit increased Abeta42ratioAbeta40 ratios in aged brain, which mimics the effect of familial mutations of Presenilin-1, Presenlin-2, and the amyloid precursor protein on Abeta production. Additionally, female mice exhibit much higher gamma-secretase activity in aged brain compared to male mice. Furthermore, both male and female mice exhibit a steady decline in Notch1 gamma-secretase activity with aging. Using a small molecule affinity probe we demonstrate that male mice have less active gamma-secretase complexes than female mice, which may account for the gender-associated differences in activity in aged brain. These findings demonstrate that aging can affect gamma-secretase activity and specificity, suggesting a role for gamma-secretase in sporadic AD. Furthermore, the increased APP gamma-secretase activity seen in aged females may contribute to the increased incidence of sporadic AD in women and the aggressive Abeta plaque pathology seen in female mouse models of AD. In addition, deceased Notch gamma-secretase activity may also contribute to neurodegeneration. Therefore, this study implicates altered gamma-secretase activity and specificity as a possible mechanism of sporadic AD during aging.

    BACKGROUND: The heart's physiological adaptation to aerobic training leads to an increase in heart chamber size, and is referred to as the Athlete's heart. However, heart dimensions are also related to body weight (BWT), body size, growth and (in some species) breed. There are few published data...... functional indices did not. Although there was no gender difference for LV dimensions, females had larger LA dimensions. In terms of breed, Anglo-Arabians had the largest LV dimensions. Regression models indicated that the included explanatory factors had a weak influence on heart dimensions. Age, body...... may therefore reflect early adaptations linked to the initiation of endurance training....

    The aim of this study was to estimate the magnitude of gender differences in hazardous drinking among middle-aged people and to analyse whether these differences are associated with contextual factors, such as public policies or socioeconomic factors. Cross-sectional design. The study population included 50- to 64-year-old residents of 16 European countries who participated in the Survey of Health, Ageing and Retirement in Europe project conducted in 2010-12 (n = 26 017). We estimated gender differences in hazardous drinking in each country. To determine whether different social context or women's empowerment variables were associated with gender differences in hazardous drinking, we fitted multilevel Poisson regression models adjusted for various individual and country-level variables, which yielded prevalence ratios and their 95% confidence intervals (95% CI). Prevalence of hazardous drinking was significantly higher in men than women [30.2% (95% CI: 29.1-31.4%) and 18.6% (95% CI: 17.7-19.4%), respectively] in most countries, although the extent of these differences varied between countries. Among individuals aged 50-64 years in Europe, risk of becoming a hazardous drinker was 1.69 times higher (95% CI: 1.45-1.97) in men, after controlling for individual and country-level variables. We also found that lower values of the gender empowerment measure and higher unemployment rates were associated with higher gender differences in hazardous drinking. Countries with the greatest gender differences in hazardous drinking were those with the most restrictions on women's behaviour, and the greatest gender inequalities in daily life. Lower gender differences in hazardous drinking seem to be related to higher consumption among women. © The Author 2015.

    This study applied a gender perspective to establish some of the anthropometric, body composition, health and socio-cultural determinants of active ageing. The variable 'active ageing' (presence/absence) was created based on cognitive and disability/illness/physical functioning, subjective health, satisfaction with life and productive activity performed, and used in predictive models to establish its relationship with anthropometric variables, physical health indicators and educational level. The sample consisted of 456 home-living individuals (169 men and 287 women; age range 54-75 years) from Madrid and Toledo in Spain. The women had a higher prevalence of obesity than the men (37.6% vs 29.0%), significantly greater fat accumulation in the abdominal area and worst perceived health (p=0.003). The frequency of active agers is higher in men than in women (38.4% vs 21.9%; peducation factors are also relevant in men.

    Full Text Available Female gender is a known risk factor for early and late mortality after coronary artery bypass graft surgery (CABG. Higher age of women at operation may influence outcome, since age per se is also an important risk factor. The purpose of our study was to analyze possible gender differences in outcome after isolated CABG in different age groups to delineate the impact of female gender and age.All patients over 60 years of age undergoing isolated CABG at our department during 2001 and 2011 were included and categorized by age into sexagenarians (2266, 16.6% women, septuagenarians (2332, 25.4% women and octogenarians (374, 32% women and assessed by gender for 30-day and 180-day mortality.Thirty-day mortality was significantly higher in women only amongst septuagenarians (7.1 vs. 4.7%, p = 0.033. Same differences apply for 180-day mortality (12.3 vs. 8.2%, p = 0.033 and estimated one-year survival (81.6 ± 4.2 vs. 86.9 ± 2.2%, p = 0.001.

However, female gender was found to be an independent predictor for 180-day mortality (HR 1.632, p = 0.001 in addition to ES, use of LIMA graft, perioperative MI, pneumonia and abnormal LV function (HR 1.013, p = 0.004; HR 0.523, p<0.001; HR 2.710, p<0.001; HR 3.238, p<0.001; HR 2.013, p<0.001.Women have a higher observed probability of early death after CABG in septuagenarians. However, female gender was not found to be an independent risk factor for 30-day, but for 180-day survival. Therefore, reduction of high impact risk factors such as perioperative MI and enhancement of LIMA use should be future goals. In view of our findings, decision for surgical revascularization should not be based on gender.

    Although frequently used with older adolescents, few studies of the factor structure, internal consistency and gender equivalence of the SDQ exists for this age group, with inconsistent findings. In the present study, confirmatory factor analysis (CFA) was used to evaluate the five-factor structure of the SDQ in a population sample of 10,254 16-18 year-olds from the youth@hordaland study. Measurement invariance across gender was assessed using multigroup CFA. A modestly modified five-factor solution fitted the data acceptably, accounting for one cross loading and some local dependencies. Importantly, partial measurement non-invariance was identified, with differential item functioning in eight items, and higher correlations between emotional and conduct problems for boys compared to girls. Implications for use clinically and in research are discussed.

    Most research to date on implicit gender stereotyping has been conducted with one age group - young adults. The mechanisms that underlie the on-line processing of stereotypical information in other age groups have received very little attention. This is the first study to investigate real time processing of gender stereotypes at different age levels. We investigated the activation of gender stereotypes in Italian in four groups of participants: third- and fifth-graders, young and older adults. Participants heard a noun that was stereotypically associated with masculine (preside "headmaster") or feminine roles (badante "social care worker"), followed by a male (padre "father") or female kinship term (madre "mother"). The task was to decide if the two words - the role noun and the kinship term - could describe the same person. Across all age groups, participants were significantly faster to respond, and significantly more likely to press 'yes,' when the gender of the target was congruent with the stereotypical gender use of the preceding prime. These findings suggest that information about the stereotypical gender associated with a role noun is incorporated into the mental representation of this word and is activated as soon as the word is heard. In addition, our results show differences between male and female participants of the various age groups, and between male- and female-oriented stereotypes, pointing to important gender asymmetries.

    Although studies document the health-enhancing effects of social engagement, they reveal little about the underlying mechanisms operating within specific organizational contexts. Limited attention is given to the role of inequality--particularly age and gender--in shaping either the organizations to which we belong or their consequences for our well-being. We address this issue by examining the Red Hat Society, a social organization for middle-aged and older women. Interviews with members (n=52) illustrate how age and gender inequality interact to shape the organization, which can be viewed as a gendered subculture of aging. Drawing on this framework, we discuss four processes through which participation generates benefits for older women involved in age- and gender-segregated organizations: enhancing social networks, countering invisibility, creating positive frames for aging experiences, and promoting youthful identities.

    Full Text Available Background: We analyzed the correlation between several factors (donor age and gender, and handling time and trace DNA concentration that participants left on different surfaces (paper, plastic, plastic coated metal while holding items in their hands or rubbing them with their fingers, their palms, and the side of the palm of the dominant hand. Material and Methods: Sixty participants took part in the study. Items were swabbed with a moistened cotton swab. DNA was isolated using the Chelex procedure and quantified by real-time PCR. Results: We found that DNA concentration transferred to an item was independent of the handling time. On the contrary, it was dependent on the item’s texture; the greatest concentration was left on plastic coated metal (PCM and the least on paper. The greatest concentration of trace DNA was left by participants from 35 to 44 years of age. Results of the study showed that men deposit a higher DNA concentration than do women. Conclusion: Item texture, donor age, and gender influence trace DNA concentration. Further investigations are necessary to fully understand the process of DNA transfer from donors to handled items.

    Intimate relationship is a significant factor that influences older adults' subjective well-being. Avoidant attachment reflects a basic working model regarding interpersonal relationships. The current study aims to test how age and gender moderate the effect of avoidant attachment to spouse on subjective well-being. Fifty-six married couples aged from 20 to 79 years in Hong Kong were recruited for the study. Their avoidant attachment to spouse and subjective well-being were measured by questionnaires. In general, avoidant attachment to spouse was found to undermine subjective well-being. More importantly, age significantly moderated the negative association between avoidant attachment and subjective well-being, but the direction of the moderating effect was opposite for husbands and wives. Compared with their younger counterparts, the detrimental effect of avoidant attachment on subjective well-being was weaker for older wives but stronger for older husbands. The results suggest that marital relationship may play different roles in different life stages for the two genders. In later adulthood, males may become more dependent on the marital relationship to maintain subjective well-being, whereas females can be relatively independent.

    Full Text Available OBJECTIVE: Cognitive impairment is associated with reductions in brain weight and volume. The factors related to morphometric brain changes in cognitively normal aging remain unknown. We aimed to identify which clinical factors are associated with morphometric brain changes in cognitively normal aging. METHODS: A cross-sectional study of 414 subjects, ≥50 years old submitted to clinical assessment and brain autopsy, after informed consent, was carried out at the São Paulo Autopsy Service, Brazil. Data on cognitive and functional evaluations were collected through structured interview applied to the next-of-kin. Brain weight (g and volume (mL measurements were obtained and adjusted for head circumference (cm. Associations between brain weight/volume and related factors were obtained through univariate and multivariate analysis. RESULTS: Participants were predominantly male (60.4%, Caucasian (69%, with mean age of 67.1 ± 10.9 years. Mean brain weight was 1219.2 ± 140.9 g, and mean brain volume was 1217.1 ± 152.3 mL. Head circumference was independently associated with low brain weight (p<0.001 and volume (p<0.001. Total and adjusted brain weight and volume decreased in some conditions. Female gender (p<0.001, hypertension (p<0.009, coronary artery disease (p<0.013 and walking assistance (p<0.011 were associated with lower adjusted brain weight while schooling was associated with higher adjusted brain weight (p<0.003. Female gender (p<0.001, age (p<0.001 and hypertension (p<0.011 were associated with low adjusted brain volume. CONCLUSION: Morphometric brain changes occur despite the absence of cognitive impairment and were predominantly associated with age, female gender, mobility impairment and cardiovascular conditions. Schooling may be a protective factor.

    The present study explored the characteristics of social categorization based on the unidimensional variation of gender or age using the Garner's Selective Attention Paradigm. The task of the experiment was to judge whether there was a mole on a person's face, and the results showed that young participants' response times were slower when the age or gender of the face stimuli varied, demonstrating that young people, rather than older people, can activate both an age category and a gender category automatically. Meanwhile, all participants' responses to the old faces were slower than that to the young faces. Females reacted faster than males, demonstrating that females tend to have an advantage for face processing.

The nature and impact of demographic and stroke-related variables on care quality provided by allied health (AH professionals is unknown.Aims: Our research explores the association of age and gender on an index of acute stroke care quality provided by AH professionals.Methods: A retrospective clinical audit of 300 acute stroke patients extracted data on AH care, patients' age and gender. AH care quality was determined by the summed compliance with 20 predetermined process indicators. Our analysis explored relationships between this index of quality, age, and gender. Age was considered in different ways (as a continuous variable, and in different categories. It was correlated with care quality, using gender-specific linear and logistic regression models. Gender was then considered as a confounder in an overall model.Results: No significant association was found for any treatment of age and the index of AH care quality. There were no differences in gender-specific models, and gender did not significantly adjust the age association with care quality.Conclusion: Age and gender were not predictors of the quality of care provided to acute stroke patients by AH professionals.Keywords: acute stroke, allied health, quality of care, age, gender

    Dietary patterns are linked to obesity, but the gender difference in the association between dietary patterns and obesity remains unclear. We explored this gender difference in a middle-aged and elderly populations in Shanghai. Residents (n = 2046; aged ≥45 years; 968 men and 1078 women) who participated in the Shanghai Food Consumption Survey were studied. Factor analysis of data from four periods of 24-h dietary recalls (across 2012-2014) identified dietary patterns. Height, body weight, and waist circumference were measured to calculate the body mass index. A log binominal model examined the association between dietary patterns and obesity, stratified by gender. Four dietary patterns were identified for both genders: rice staple, wheat staple, snacks, and prudent patterns. The rice staple pattern was associated positively with abdominal obesity in men (prevalence ratio (PR) = 1.358; 95% confidence interval (CI) 1.132-1.639; p = 0.001), but was associated negatively with general obesity in women (PR = 0.745; 95% CI: 0.673-0.807; p = 0.031). Men in the highest quartile of the wheat staple pattern had significantly greater risk of central obesity (PR = 1.331; 95% CI: 1.094-1.627; p = 0.005). There may be gender differences in the association between dietary patterns and obesity in middle-aged and elderly populations in Shanghai, China.

  13. Narratives of attachment in middle childhood: do gender, age, and risk-status matter for the quality of attachment?

    Gloger-Tippelt, Gabriele; Kappler, Gregor

    2016-12-01

    Attachment in middle childhood increasingly attracts the interest of developmental psychologists and clinicians. Recent studies using attachment narratives elicited by story stems reported gender-specific aspects of attachment development, potentially evoked by developmental tasks during this period of the life span. There is evidence that children with risk factors present more insecure and disorganized attachment narratives compared to children without risk. Yet, there is little research concerning the joint effects of gender, risk, and age for attachment classifications. The paper presents a pooled analysis of 22 samples (eight risk samples) including 887 children (411 girls), aged between 4.5 and 8.5 years who were assessed with the same "German Attachment Story Completion Procedure" (GASCP). Girls were 1.8 times more likely to present secure and 0.4 times less likely to present disorganized narratives compared to boys when controlling for risk status and age. Children from risk samples were more likely (odd ratio 5.4) to display disorganized and less likely to show a secure attachment (odd ratio 0.3) compared to those from no-risk samples in multilevel logistic regressions. Remarkably, the effect of risk was not moderated by age and gender, and gender effects were not moderated by age.

    The human finger plays an extremely important role in tactile perception, but little is known about how age and gender affect its biophysical properties and their role in tactile perception. We combined studies on contact characteristics, mechanical properties and surface topography to understand age and gender effects on the human finger. The values obtained regarding contact characteristics (i.e. adhesive force) were significantly higher for women than for men. As for mechanical properties (i.e. Young's modulus E), a significant and positive correlation with age was observed and found to be higher for women. A positive correlation was observed between age and the arithmetic mean of surface roughness for men. However, an inverse age effect was highlighted for women. The age and gender effects obtained have never been reported previously in the literature. These results open new perspectives for understanding the weakening of tactile perception across ages and how it differs between men and women. PMID:28878982

    Objective: To investigate the age- and gender-related changes in upper and lower incisors' position and inclination in different vertical craniofacial relationships. Materials and Methods: A retrospective study on patients' records of age 8–48 years. The sample was divided based on Frankfort mandibular plane angle into three groups; normal, high, and low angle groups. It was then subdivided according to age. Upper and lower incisors' inclinations and positions were assessed from lateral cephalometric radiographs. Gender and age associations and effects size were calculated using two-way ANOVA tests. Significance level was set at P 0.05). All significant associations and effects were found in the low angle group only. A significant association was found between gender and upper incisor inclination (P < 0.05) with medium effect size (0.13 ≤ ηp2 < 0.26). An association is also found between age × gender interaction and upper incisor inclination and lower incisor position (P < 0.05) with large effect size (0.26 ≤ ηp2). Conclusion: Age- and gender-related upper and lower incisor changes were found to be significant in subjects with decreased vertical skeletal pattern only. The upper incisor inclination and the lower incisor position were the most affected variables with age and gender. PMID:27843888

    The aim of the present paper is to show how the variation of the EEG frontal cortical asymmetry is related to the general appreciation perceived during the observation of TV advertisements, in particular considering the influence of the gender and age on it. In particular, we investigated the influence of the gender on the perception of a car advertisement (Experiment 1) and the influence of the factor age on a chewing gum commercial (Experiment 2). Experiment 1 results showed statistically significant higher approach values for the men group throughout the commercial. Results from Experiment 2 showed significant lower values by older adults for the spot, containing scenes not very enjoyed by them. In both studies, there was no statistical significant difference in the scene relative to the product offering between the experimental populations, suggesting the absence in our study of a bias towards the specific product in the evaluated populations. These evidences state the importance of the creativity in advertising, in order to attract the target population. PMID:27313602

    Full Text Available In developed countries, falls in older people represent a rising problem. As effective prevention should start before the risk becomes evident, an early predictor is needed. Single stance instability would appear as a major risk factor. Aims of the study were to describe single stance stability, its sensory components, and their correlation with age and gender. A random sample of 597 older adults (319 men, 278 women living at home, aged 65–84, was studied. Stability tests were performed with an electronic postural station. The single stance test showed the impairment of single stance stability in older individuals (75–84 yrs. The significant decline of stability in the older subjects may be explained by the impairment of proprioceptive control together with the decrease in compensatory visual stabilization and emergency responses. Younger subjects (65–74 yrs exhibited better, but still inadequate, proprioceptive control with compensatory visual stabilization. Gender differences appeared in older subjects: women were significantly less stable than men. The measurement of the sensory components of single stance stability could aid in the early detection of a decay in antigravity movements many years before the risk of falling becomes evident. Adequate proprioceptive control could mitigate the effects of all other risks of falling.

  13. Exploiting quality and texture features to estimate age and gender from fingerprints

    Science.gov (United States)

    Marasco, Emanuela; Lugini, Luca; Cukic, Bojan

    2014-05-01

    Age and gender of an individual, when available, can contribute to identification decisions provided by primary biometrics and help improve matching performance. In this paper, we propose a system which automatically infers age and gender from the fingerprint image. Current approaches for predicting age and gender generally exploit features such as ridge count, and white lines count that are manually extracted. Existing automated approaches have significant limitations in accuracy especially when dealing with data pertaining to elderly females. The model proposed in this paper exploits image quality features synthesized from 40 different frequency bands, and image texture properties captured using the Local Binary Pattern (LBP) and the Local Phase Quantization (LPQ) operators. We evaluate the performance of the proposed approach using fingerprint images collected from 500 users with an optical sensor. The approach achieves prediction accuracy of 89.1% for age and 88.7% for gender.

    Most studies of perceived discrimination have been cross-sectional and focused primarily on mental rather than physical health conditions. We examined the associations of perceived racial and gender discrimination reported in adulthood with early life factors and self-reported physician diagnosis of chronic physical health conditions. We used data from a racially diverse birth cohort of U.S. women (n = 168; average age, 41 years) with prospectively collected early life data (e.g., parental socioeconomic factors) and adult reported data on perceived discrimination, physical health conditions, and relevant risk factors. We performed modified robust Poisson regression owing to the high prevalence of the outcomes. Fifty percent of participants reported racial and 39% reported gender discrimination. Early life factors did not have strong associations with perceived discrimination. In adjusted regression models, participants reporting at least three experiences of gender or racial discrimination had a 38% increased risk of having at least one physical health condition (relative risk, 1.38; 95% confidence interval, 1.01-1.87). Using standardized regression coefficients, the magnitude of the association of having physical health condition(s) was larger for perceived discrimination than for being overweight or obese. Our results suggest a substantial chronic disease burden associated with perceived discrimination, which may exceed the impact of established risk factors for poor physical health.

    2010-07-01

    We explored whether gender moderated the influence of other factors on solo spousal caregiving. The subsample (N = 452) from the AHEAD study included elderly care recipients (CRs) receiving IADL assistance and their spouses. Logistic regression modeled the likelihood of solo spousal IADL care. Gender moderation was tested by product terms between CRs' gender and measures of partners' health, potential helpers, and sociodemographic characteristics. As numbers of CRs' IADLs and couples' proximate daughters increased, wives less often received care solely from their husbands, but husbands' receipt of care from their wives was unaffected. Age differences between spouses and CRs affected solo spousal caregiving to wives and husbands in opposite ways. Regardless of gender, CRs' number of ADL limitations and spouses with IADL or ADL limitations reduced the likelihood of solo spouse care. Identifying circumstances influencing solo spouse caregiving differently among couples with frail wives and husbands facilitates gender sensitive services.

    Background: Little is known about the variation in exposure to toxic metals by age and gender and other potential modifying factors. We evaluated age and gender differences by measurements of metal/element concentrations in urine in a rural population in Matlab, Bangladesh, in three age groups: 8-12 (N=238), 14-15 (N=107) and 30-88 (N=710) years of age, living in an area with no point sources of metal exposure but where elevated water arsenic concentrations are prevalent. Results: We found marked differences in urine concentrations of metals and trace elements by gender, age, tobacco use, socioeconomic and nutritional status. Besides a clearly elevated urinary arsenic concentration in all age groups (medians 63-85 {mu}g As/L), and despite the low degree of contamination from industries and traffic, the urine concentrations of toxic metals such as cadmium and lead were clearly elevated, especially in children (median 0.31 {mu}g Cd/L and 2.9 {mu}g Pb/L, respectively). In general, women had higher urinary concentrations of toxic metals, especially Cd (median 0.81 {mu}g/L) compared to men (0.66 {mu}g/L) and U (median 10 ng/L in women, compared to 6.4 ng/L in men), while men had higher urinary concentrations of the basic and essential elements Ca (69 mg/L in men, 30-50 years, compared to 52 mg/L in women), Mg (58 mg/L in men compared to 50 mg/L in women), Zn (182 {mu}g/L in men compared to 117 {mu}g/L in women) and Se (9.9 {mu}g/L in men compared to 8.7 {mu}g/L in women). Manganese was consistently higher in females than in males in all age groups, suggesting a biological difference between females and males in Mn metabolism. Increasing socioeconomic status decreased the toxic metal exposure significantly in children and especially in men. Poor iron status was detected in 17% of children, adolescents and women, but only in 6% of men. Also zinc deficiency was more prevalent in females than in males. Conclusions: Women and children seemed to be more at risk for toxic

    Little is known about the factorial invariance across gender and age for self-report measures of social anxiety in adolescence. This study examined the factorial invariance and latent mean differences of the Social Anxiety Scale for Adolescents (SAS-A) across gender and age groups in 1570 Spanish adolescents (54% girls), ranging in age from 14 to 17 years. Equality of factor structures was compared using multi-group confirmatory factor analyses. Measurement invariance for the correlated three-factor model of the SAS-A was found across gender and age samples. Analyses of latent mean differences revealed that girls exhibited higher means than boys on two SAS-A subscales, Fear of Negative Evaluation and Social Avoidance and Distress-New (SAD-New). In addition, on the SAD-New subscale, the structured means significantly diminished from 14-year olds to 16- and 17-year olds and from 15-year olds to 17-year olds. Findings are discussed in terms of the use of the SAS-A with Spanish adolescents. Copyright © 2010 Elsevier Ltd. All rights reserved.

    To assess the impact of risk factors such as age, gender, ethnicity, family history, body mass index (BMI), waist circumference and hypertension, on the development of type 2 diabetes mellitus in the Trinidadian population. A cross-sectional case control study comprised 146 non-diabetics and 147 type 2 diabetics ≥18 years of age, from North Central, South West and Eastern regions of Trinidad. Cross-tabulations revealed a significant difference between type 2-diabetes and age at pdiabetes and family history, ethnicity, waist circumference and hypertension at pdiabetics and type 2 diabetics being, 130.62 (±2.124) and 141.35 (±2.312), respectively. No significant difference was observed between type 2 diabetes and gender and BMI. Age was the most significant risk factor of type 2 diabetes. Therefore it can be concluded that family history, ethnicity, waist circumference and hypertension are more significant risk factors of this disease than BMI and gender in the Trinidadian population.

    Full Text Available Objective: We investigated the effects of age on mood and mental health-mediated emotion regulation, such as cognitive reappraisal and expressive suppression, and examined whether these relationships differ according to gender. Method: We recruited 936 Japanese participants. They comprised six age groups ranging from 20 to 70 years old, with 156 participants in each age group and equal numbers of men and women. Results: Structural equation model analysis showed that older participants were more likely to use cognitive reappraisal, further enhancing positive mood and reducing negative mood, whereas, age did not affect expressive suppression. Moreover, expressive suppression had a smaller impact on mood than cognitive reappraisal. A multi-group analysis showed significant gender differences. In men, cognitive reappraisal increased with age and influenced mood more positively than in women. Discussion: Our findings indicated gender differences in aging effects on emotion regulation. We discussed about these results from the cognitive process, motivation to emotion regulation, and cultural differences.

    Little research has explored the intersection of aging and sexuality. This qualitative study is informed by a life course approach and narrative gerontology methods. Semistructured interviews were conducted with 13 women age 55 and older to explore the effects of gender, aging, and living environment on past and current sexual experiences. Subthemes from each major theme are discussed, including: (a) messages about and perceived effects of gender, (b) perceived effects of aging, and (c) perceived effects of living environment. Findings support the use of dynamical systems theory to study women's sexual experiences.

    The study reports an investigation of stress levels, gender and personality dimensions in a sample of school teachers. The Professional Life Stress Scale (PLSS) was used to assess teachers' stress levels and the Eysenck Personality Questionnaire (EPQ) was used to define their personality dimensions (Extroversion-Introversion, Neuroticism-High Psychoticism-Low Psychoticism). The study sample consisted of 95 teachers, 51 females and 44 males. Results revealed that the majority of teachers sampled, 72.6 per cent, were experiencing moderate levels of stress, and 23.2 per cent serious levels. T-test results showed no significant difference between male and female teachers in stress levels. Correlation analysis between stress level and personality dimensions revealed significant positive correlation between stress and psychoticism. A significant negative correlation emerged between stress and extroversion, and a significant positive correlation between stress and neuroticism. A multiple regression analysis revealed that extroversion and neuroticism were the best predictors of stress levels. Overall, the results therefore indicated that personality dimensions appear to contribute more to stress levels than do the variables of either age or gender.

    Full Text Available The ability to attribute different mental states to distinct individuals, or Theory of Mind (ToM, is widely believed to be developed mostly during preschool years. How different factors such as gender, number of siblings or coarse personality traits affect this development is not entirely agreed upon. Here, we introduce a computerized version of the scaled ToM suite of tasks introduced by Wellman and Liu (2004, which allows us to meaningfully test ToM development on children 6 to 8-years old. We find that kids this age are still not entirely proficient in all ToM tasks, and continue to show a progression of performance with age. By testing this age range, too, we are able to observe a significant advantage of girls over boys in ToM performance. Other factors such as number of siblings, birth order, and coarse personality traits show no significant relation with the ToM task results. Finally, we introduce a novel way to quantify the scaling property of the suite involving a sequence of set inclusions and also, a comparison between specially tailored sets of logistic models. These measures confirm the validity of the scale in the 6 to 8-years old range.

    We investigated the relationship between fasting insulin level and various hemostatic factors, including fibrinolytic factors (active plasminogen activator inhibitor-1 (PAI-1), tissue type plasminogen activator (tPA)-PAI-1 complex, plasmin-alpha 2-plasmin inhibitor (PIC), and D-dimer), coagulation factors (activated factor VII, factor VII coagulant activity and antigen, factor VIII, factor X, and fibrinogen), coagulation inhibitors (antithrombin III, heparin cofactor II, and protein C), and an acute phase marker (sialic acid) in 102 healthy individuals aged > or = 75 years (46 men and 56 women). Active PAI-1 levels had a significant negative correlation with PIC levels (r = -0.342, P = 0.0006), indicating that PAI-1 influences in vivo fibrinolytic activity in the very elderly. Gender differences were found in the relationship between insulin and hemostatic abnormalities, with the insulin level being positively correlated with coagulation factors in men (factor VIII activity: r = 0.422, P sex.(ABSTRACT TRUNCATED AT 250 WORDS)

    Perceptions of age influence how we evaluate, approach, and interact with other people. Based on a paramorphic human judgment model, the present study investigates possible determinants of accuracy and bias in age estimation across the adult life span. For this purpose, 154 young, middle-aged, and older participants of both genders estimated the age of 171 faces of young, middle-aged, and older men and women, portrayed on a total of 2,052 photographs. Each face displayed either an angry, fearful, disgusted, happy, sad, or neutral expression (FACES database; Ebner, Riediger, & Lindenberger, 2010). We found that age estimation ability decreased with age. Older and young adults, however, were more accurate and less biased in estimating the age of members of their own as compared with those of the other age group. In contrast, no reliable own-gender advantage was observed. Generally, the age of older faces was more difficult to estimate than the age of younger faces. Furthermore, facial expressions had a substantial impact on accuracy and bias of age estimation. Relative to other facial expressions, the age of neutral faces was estimated most accurately, while the age of faces displaying happy expressions was most likely underestimated. Results are discussed in terms of methodological and practical implications for research on age estimation.

    We examined sexual orientation differences in adolescent smoking and intersections with race/ethnicity, gender, and age. We pooled Youth Risk Behavior Survey data collected in 2005 and 2007 from 14 jurisdictions; the analytic sample comprised observations from 13 of those jurisdictions (n = 64,397). We compared smoking behaviors of sexual minorities and heterosexuals on 2 dimensions of sexual orientation: identity (heterosexual, gay-lesbian, bisexual, unsure) and gender of lifetime sexual partners (only opposite sex, only same sex, or both sexes). Multivariable regressions examined whether race/ethnicity, gender, and age modified sexual orientation differences in smoking. Sexual minorities smoked more than heterosexuals. Disparities varied by sexual orientation dimension: they were larger when we compared adolescents by identity rather than gender of sexual partners. In some instances race/ethnicity, gender, and age modified smoking disparities: Black lesbians-gays, Asian American and Pacific Islander lesbians-gays and bisexuals, younger bisexuals, and bisexual girls had greater risk. Sexual orientation, race/ethnicity, gender, and age should be considered in research and practice to better understand and reduce disparities in adolescent smoking.

    To design and validate a questionnaire for young women on gender-determinant factors in contraception. A questionnaire was developed from conversations with young women attending contraception clinic in the Health Promotion Municpal Centre, Zaragoza. A total of 200 young women between the ages of 13 and 24 self-completed the questionnaire, with only one no response. Several items were analysed: reliability, using Cronbach's alpha coefficient, and construct validity by analysis of the main components with eigenvalues above 1, and Quartimax rotation with Kaiser normalisation. The questionnaire contained 36 items and took 10minutes to self-complete. There was good internal consistency, with a Cronbach's alpha 0,853. Twelve factors were established with an explanation of 61.42% variance, and three descriptive lines: relationship dimension («submissive attitude», «blind attitude», «let go due to affection», «dominant partner»), gender identity («maternity as identity», «non-idealised maternity», «traditional role», «insecurity», «shame») and caring. This questionnaire enabled gender determinant-factors that take part in contraception to be identified, and will be useful to find out how the different ways of relating between the sexes influence the problems of sexual and reproductive health in young women in our environment.

    2015-03-01

    The purpose of the study is to examine healthy eating habits of the population of Serbia through three dimensions: knowledge, problems, and feelings as well as to determine whether there are any differences between genders and among different age-groups. The research instrument was an Eating Habits Questionnaire (EHQ) which consisted of 35 items. There were 382 respondents involved in the study. The reliability and factor structure of the questionnaire were verified by using factor analysis. The results of MANOVA showed that there is a significant difference in the habits concerning healthy eating between men and women [F (3,378)=4.26, p=0.006; Wilks' Lambda=0.97]. When the results for the dependent variables (knowledge, problems, and feelings) were considered separately, it was determined that there is no significant difference between men and women, which confirms the results of the t-test. The effect of age on the three dimensions of healthy eating habits was examined within three age-groups, by using ANOVA. The results showed that knowledge about healthy eating increases with age [F (2,379)=6.14, p=0.002] as well as positive feelings which occur as a result of healthy eating [F (2,379)=3.66, p=0.027]. Unlike ANOVA, MANOVA showed difference among the age-groups only when it came to the 'knowledge' variable. This study is important as it shows the current state of awareness on healthy eating habits in the researched populace and may be the basis for further research in this field in Serbia.

Trained nutritionists applied five instruments (Cognition/ Depression/ Functionality/ Nutrition/ Appetite to 285 subjects with majorities of women (64%, aged <80y (61% and home residents (54%.Results. Multivariable regression models were generated for each instrument using age, gender and residency as independent variables. Age was associated with worsening scores in the five instruments whereas residency showed association in three instruments, and gender in two. Score-age regressions by place of residency showed differences suggesting that Mundet residents had increasingly worse scores with increasing age, than home dwellers for Cognition, Depression and Nutrition. Also, living at home prevented the worsening of Depression with increasing age. In contrast, Functionality and Appetite deteriorated at a similar rate for home and Mundet residents suggesting an inhability of these two instruments to dicriminate between settings. Score-age regressions by gender suggested males have less cognitive problems at 60 and 80 years of age but not at 100, and better appetite than women at all ages.Conclusions. Increasing age proved to be associated to worsening scores in the five instruments but only three were able to detect differences according to setting. An interesting observation was that living at home appeared to prevent the Depression increase with increasing age seen in Mundet residents.

    Full Text Available Classification of gender from fingerprints is one of the important steps in forensic anthropology. This forensic anthropology is used to identify the gender of a criminal in order to minimize the suspects list of search. A very few researcher have worked on gender classification using fingerprints and have gain the competitive results. In this work we are trying to fuse the fingerprint and age biometrics for gender classification. The real fingerprints were collected from different age groups such as 15-20 years and 20- 60 years of the rural and urban people. According to this experimental observation soft biometric information can be used significantly to improve the recognition performance of biometric system. The overall performance of the proposed method is found to be satisfactory and more competitive.

    We examined the association of gender, ethnicity, age, and education with 60 Rorschach scores using three clinical and nonclinical samples of adults and youths (ns = 640, 249, and 241). As anticipated for our data sets, there were no reliable associations for gender, ethnicity, or adult age. However, in adults years of education was associated with variables indicative of complexity, the articulation of subtlety and nuance, cognitive synthesis, and coping resources. In the clinical sample of youths, increasing age was primarily associated with more conventional perception and less illogical thought processes. Limitations are discussed in conjunction with further research that could address them, along with implications for applied practice.

    Aging and gender have a strong influence on the functional capacity of the immune system. In general, the immune response in females is stronger than that in males, but there is scant information about the effect of aging on the gender difference in the immune response. To address this question, we performed a transcriptomic analysis of peripheral blood mononuclear cells derived from elderly individuals (nonagenarians, n = 146) and young controls (aged 19-30 years, n = 30). When compared to young controls, we found 339 and 248 genes that were differentially expressed (p1.5 or human immune system are significantly different in males and females.

    This study is the first epidemiologically based study of basal levels of serum pancreatic polypeptide (s-PP). The basal level of serum PP has become a field of interest mainly due to the role of PP as an endocrine tumour marker, and as a marker of pancreatic neuroendocrine function after pancreas...... a monospecific radioimmunoassay. Fasting serum pancreatic polypeptide depended on age and gender. The results demonstrated that fasting pancreatic polypeptide levels increase exponentially with age. Fitted separately for each sex, basal serum pancreatic polypeptide was found to increase by approximately 3% per...... reports on the fasting levels of serum pancreatic polypeptide are most likely due to lack of adjustment for age and gender. Thus, variation due to age and gender should be considered in evaluating fasting levels of serum pancreatic polypeptide. Whether similar considerations are important when evaluating...

    Full Text Available Introduction. Patient’s subjective evaluation of dental appearance and aesthetics is becoming an increasingly important factor in aesthetic treatments and prosthetic therapy. Objective. The aim of this study was to investigate the influence of age, education level, gender, and different dental status and the appearance of the upper anterior teeth (color, size, shape, position and alignment of the anterior teeth on the satisfaction of the respondents with dental appearance and aesthetics of their upper anterior teeth and their desire for improvement. Methods. The study encompassed 480 people aged 20 to 50 years with an average age of 30.84 years. There were 236 male and 244 female subjects. The respondents were interviewed using a questionnaire specially designed for the purpose of this research. For the study, the subjects were divided into the following three age groups: the younger age group (20-30 years of age, the middle age group (31-40 years of age, and the older age group (41-50 years of age. Results. The conducted study did not reveal statistical significance with respect to gender in any of the examined parameters (p > 0.05. A little more than one half of the respondents in each age group were satisfied with their dental appearance and aesthetics (60.3% of the respondents in the age group of 20-30 years, 55.7% in the age group of 31-40, and 53.7% in the age group of 41-50 years of age. Satisfaction with dental appearance and aesthetics increases linearly with the increase in the level of education and was the highest among the respondents with university degree (33.3%. Conclusion. Female respondents were more dissatisfied with their dental appearance and aesthetics as compared with male respondents, but the difference was found to be non-significant. Patients with higher education level were more satisfied with their dental appearance and aesthetics than those with lower education.

    2013-05-01

    Full Text Available There is a lack of empirical data segregation on factors affecting gender as the variable of interest. However, previous research had indicated several factors that affect business performances among small-scale enterprise owners. Using feminist theory and a descriptive survey research design, data were collected from fifty (50 small-scale enterprise owners that were purposively chosen across the study area. The findings show that the factors that were significant for female were significantly different from male. For female small scale enterprise owners, marital status (64% Age of Children (68%, Role Model/ advisors (58% were significant factors that affect their business performance. For male small-scale enterprise owners, Friends (70%, a lack of Government support (80%, inability to display innovativeness (78% and Risk-Taking (84% were significant for male. Lack of availability of capital and finances were significant for the two. Other factors that affect performance include friends, inadequate training and business location. Adequate knowledge of factors that affect gender enterprise performance will go a long way in alleviating these problems. Small-scale enterprises should be supported for poverty alleviation, especially among women and for the nation’s economic development

    Full Text Available Physiologically aging refers to the impaired ability to maintain homeostasis during external as wellas internal stresses. The sympathetic nervous system becomes tonically, progressively and markedlyactivated with aging in humans. Study is done to measure the cardiovascular sympatheticdysfunctions in the males and females of the different age groups. Total 80, healthy subjects nothaving any major illness and any chronic addiction, were selected for the study. All the subjects wereevaluated by using “CANWIN cardiac autonomic neuropathy analyzer” using the tests like Pulse rateby Palpatory method, Blood Pressure response to sudden standing and Sustained Handgrip test. In all the elderly subjects the sympathetic system was over activated and this over activation of the sympathetic system became more severe as the age advanced. Aging is accompanied by a greater increase in sympathetic activity in women than in men, independent of menopausal status. The study concludes that there is more marked influence of age on sympathetic nervous system activation and impaired sensitivity of baroreceptors in women than men.

    2013-12-01

    The present paper investigated gender differences on life satisfaction and self-esteem as well as the association between self-esteem and life satisfaction in Norwegian adolescents aged 13-18 years. The potential moderating role of gender and age in the relation between self-esteem and life satisfaction was also investigated. A total of 1,239 adolescents from public elementary and secondary schools in mid-Norway participated in the school-based survey study. Mean score differences on the variables used in the study were tested using t tests. Hierarchical multiple regression analysis was used to evaluate the association between self-esteem and life satisfaction, controlled for gender, age, stress, subjective health, and chronic health conditions. The results showed that boys scored higher than girls on both self-esteem and life satisfaction. Self-esteem was positively associated with life satisfaction, explaining 24 % of the variance. However, no interaction effect of gender × self-esteem or age × self-esteem was found in relation to life satisfaction. The results give support for that boys report higher self-esteem and life satisfaction than girls. Self-esteem has a positive role in association with adolescents' life satisfaction, and this relationship is equally strong for both genders and across age.

    Directory of Open Access Journals (Sweden)

    Steinunn Rögnvaldsdóttir

    2012-12-01

    Full Text Available Icelandic women have through the years earned less occupational and supplemental pensions and depended more than men do on the basic pension of social security. Although women’s labour market participation has increased, the gender pay gap, unpaid labour in homes, and women’s fewer working hours in paid labour results in the extension of the labour market gender discrimination into old age. The structure of Icelandic pension funds is fundamentally male biased because of its tight connection to employment, despite the absence of direct discrimination factors. The article provides an overview of implications for a more women friendly pension system; based on multi-national research; the analysis of the Icelandic pension system, and statistical information on older women and men’s economic situation in Iceland. Adequate basic pension, elimination of labour market gender discrimination, and males taking greater responsibility for care- and housework, are some of the key issues in creating a more gender equal pension system. Sharing of pensions between spouses, the responsibility of pension-funds and companies, and possibilities of care credit systems to promote gender equality are also discussed.

  15. Gender and age are associated with healthy food purchases via grocery voucher redemption.

    Hardin-Fanning, Frances; Gokun, Yevgeniya

    2014-01-01

    Grocery vouchers that specifically target foods associated with reduced cardiovascular disease (CVD) risk result in increased consumption of those foods. In regions with disproportionately high CVD rates, there is little research concerning the impact of vouchers on purchases of risk-reducing foods when there are no restrictions placed on grocery voucher redemption. Since many food assistance programs place few restrictions on type of foods that can be purchased, identifying demographic factors associated with purchasing habits is a prerequisite to promoting healthy eating. The purpose of this study was to determine the associations of age, gender, education and income level with purchasing of healthful foods through the use of a grocery voucher in a rural food desert (poverty rate of ≥20% and ≥33% of residents living >16 km from a large grocery store) with high rates of chronic disease. The effectiveness of an intervention that included a media campaign, a $5 grocery voucher, local heart healthy food branding and a grocery store event was tested. Brief nutritional articles were published in both local newspapers during four consecutive weeks. These articles explained the physiological actions of healthy foods and listed a health-promoting recipe. During the fourth week of the media campaign, a voucher for a $5 grocery gift card redeemable at one of either community grocery stores was also printed in both local newspapers. In each store, foods that are known to be associated with a reduced risk of CVD were marked with a blue logo. Participants (N=311) completed a questionnaire that assessed demographics and usual servings of fruits, vegetables and grains. Participants received a $5 grocery card and a list of labelled foods. Returned grocery receipts were stapled to the questionnaires to analyse the relationship between demographics and food choices. Participants who bought at least one labelled food item were older (M=48.5, SD=14.7) than those who did not buy

    Mitral annular motion (MAM) and tricuspid annular motion (TAM) velocities obtained by pulsed tissue Doppler echocardiography have been used to evaluate left ventricular (LV) and right ventricular (RV) functions. Although TAM velocity has been clinically applied for evaluating various cardiac diseases, the effects of age and gender remain unclear. Therefore, we aimed to determine the effects of age and gender on TAM velocity in normal hearts. We randomly selected 265 subjects (mean age, 59 years; range, 20-89 years) without abnormal clinical, electrocardiographic, and echocardiographic findings from a pool of subjects who had undergone transthoracic echocardiography. They were classified into four age groups: 20-39, 40-59, 60-79, and >80 years. Pulsed wave Doppler was applied to obtain MAM velocity of the lateral side and TAM velocity of the RV free wall side. The peak systolic (s'), early diastolic (e'), and atrial systolic (a') velocities of MAM and TAM were measured in all subjects. While MAM-s' (r=-0.267, p<0.001) correlated with age, TAM-s' did not (p=0.755). TAM-s' in any age groups had no significant gender differences. TAM-e' (r=-0.447, p<0.001) and MAM-e' (r=-0.724, p<0.001) correlated with age, respectively. In those aged 40-59 years, both TAM-e' (p=0.002) and MAM-e' (p=0.048) in females were significantly higher than those in males. The gender differences diminished in the ≥60 years age groups. There was no age-associated decline in TAM-s', while TAM-e' varied with age and gender as did MAM-e'. Although the same criteria for the TAM-s' can be used for identifying abnormal RV systolic function regardless of age and gender, age and gender differences must be considered when one utilizes the TAM-e' for the diagnosis or management of cardiovascular disease.

    This aim was to examine differences on lumbar lordosis and thoracic kyphosis in standing position by gender, age and weight status in healthy subjects using a noninvasive method. A total of 297 women (36.6 ± 7.3 years) and 362 men (39.8 ± 7.5 years) participated in this study. Participants were categorized according to the international BMI (kg/m2) cut-off points. Age was stratified by ten years increments starting from 20 y. Men showed smaller lumbar lordosis (17.3 ± 9.3) and larger thoracic kyphosis (42.8 ± 8.8°) than women (29.6 ± 11.3 and 40.4 ± 9.5° respectively; both p curvature. The results of this study suggest that gender could be the only determinant factor of lumbar lordosis in healthy people.

    2015-06-01

    This study is aimed at testing the measurement properties of the Life Orientation Test-Revised (LOT-R) for the assessment of dispositional optimism by employing item response theory (IRT) analyses. The LOT-R was administered to a large sample of 2,862 Italian adults. First, confirmatory factor analyses demonstrated the theoretical conceptualization of the construct measured by the LOT-R as a single bipolar dimension. Subsequently, IRT analyses for polytomous, ordered response category data were applied to investigate the items' properties. The equivalence of the items across gender and age was assessed by analyzing differential item functioning. Discrimination and severity parameters indicated that all items were able to distinguish people with different levels of optimism and adequately covered the spectrum of the latent trait. Additionally, the LOT-R appears to be gender invariant and, with minor exceptions, age invariant. Results provided evidence that the LOT-R is a reliable and valid measure of dispositional optimism.

    2013-01-01

    This study investigates the sex lives of Korean older adults (i.e., those over 60 years) and attempts to identify gender-related factors influencing sexual satisfaction. It used data from the 2008 Korean National Survey on Older Adults conducted by the Ministry of Health, Welfare, and Families. Of the 15,146 individuals who had taken part in the 2008 study, secondary analysis was conducted with data from 3360 persons who had spouses and were willing to respond to sex-related questions in a face-to-face interview. The mean age of male and female subjects was 67.34 and 66.86 years respectively. In the male subjects, sexual frequency, followed by marital satisfaction and cognitive function, had the greatest effect on sexual satisfaction. These three variables together accounted for 21% of the male subjects' sexual satisfaction. In the female subjects, marital satisfaction, followed by frequency of sexual activity, absence of depressive symptoms, age, and length of cohabitation with spouse, had the greatest effect on sexual satisfaction. These five variables together explained 11% of their sexual satisfaction. This study indicates that sexual frequency and physical factors have the most important effects on the sex lives of older men, while older women value psychosocial and relational factors more highly. Therefore, interventions aiming to improve sexual satisfaction in older adults should take gender differences into account.

HYPOTHESIS: Distinct PRL dynamics reflect relatively distinct (combinations of subject variables, such as gender, age, and BMI. LOCATION: Clinical Research Unit. SUBJECTS: Seventy-four healthy adults aged 22-77 yr (41 women and 33 men, with BMI 18.3-39.4 kg/m(2. MEASURES: Immunofluorometric PRL assay of 10-min samples collected for 24 hours. RESULTS: Mean 24-h PRL concentration correlated jointly with gender (P<0.0001 and BMI (P = 0.01, but not with age (overall R(2 = 0.308, P<0.0001. Nadir PRL concentration correlated with gender only (P = 0.017 and peak PRL with gender (P<0.001 and negatively with age (P<0.003, overall R(2 = 0.325, P<0.0001. Forward-selection multivariate regression of PRL deconvolution results demonstrated that basal (nonpulsatile PRL secretion tended to be associated with BMI (R(2 = 0.058, P = 0.03, pulsatile secretion with gender (R(2 = 0.152, P = 0.003, and total secretion with gender and BMI (R(2 = 0.204, P<0.0001. Pulse mass was associated with gender (P = 0.001 and with a negative tendency to age (P = 0.038. In male subjects older than 50 yr (but not in women approximate entropy was increased (0.942±0.301 vs. 1.258±0.267, P = 0.007 compared with younger men, as well as spikiness (0.363±0.122 vs. 0463±2.12, P = 0.031. Cosinor analysis disclosed higher mesor and amplitude in females than in men, but the acrophase was gender-independent. The acrophase was determined by age and BMI (R(2 = 0.186, P = 0.001. CONCLUSION: In healthy adults, selective combinations of gender, age, and BMI specify distinct PRL dynamics, thus requiring balanced representation of these variables in comparative PRL studies.

    Introduction: Studies have indicated that elderly anthropometric dimensions will different for each person. To determine whether there are differences in the anthropometric data of Javanese elderly, this study will analyze whether the variables of age, gender, origin, and body mass index (BMI) have been associated with elderly anthropometric dimensions. Age will be divided into elderly and old categories, gender will divide into male and female, origins were divided into Yogyakarta and Central Java, and for BMI only use the normal category. Method: Anthropometric studies were carried out on 45 elderly subjects in Sleman,Yogyakarta. Results and Discussion: The results showed that some elderly anthropometric dimensions were influenced by age, origin, and body mass index but gender doesn't significantly affect the elderly anthropometric dimensions that exist in the area of Sleman. The analysis has provided important aid when designing products that intended to the Javanese elderly Population.

    This study examined the factor structure of a scale based on the four-dimensional gender identity model (Egan and Perry, 2001) in 726 Chinese elementary school students. Exploratory factor analyses suggested a three-factor model, two of which corresponded to "Felt Pressure" and "Intergroup Bias" in the original model. The third factor "Gender Compatibility" appeared to be a combination of "Gender Typicality" and "Gender Contentment" in the original model. Follow-up confirmatory factor analysis (CFA) indicated that, relative to the initial four-factor structure, the three-factor model fits the current Chinese sample better. These results are discussed in light of cross-cultural similarities and differences in development of gender identity.

    While stereotypes about gender, race, and age (particularly old age) have been studied independently, few have examined the content of compound stereotypes that consider the intersection of gender, race, and age. Using a within-subjects design, we examined stereotypes as a function of target gender (male, female), race (Black, White), and age across the life span (adolescent, young adult, middle-aged, young-old, and old-old). Participants rated 20 target groups on 10 attributes representative of either an agentic (e.g., ambitious) or communal (e.g., considerate) orientation. Participants were presented only with categorical information (e.g., Black, 85-year-old, males), and ordering of categorical information and target groups was counterbalanced across participants. We hypothesized differential effects of target gender and race as a function of age. Multivariate analyses of variance on each attribute revealed significant main effects that supported traditional stereotype research, but significant interactions revealed a more complicated picture. Overall, results showed that while gender stereotypes about agency and communion generally hold up across the life span, they are more applicable to White than Black targets. Results also supported the notion that we hold unique stereotypes based on multiple social categories rather than simply perceiving one social category as more salient than another, which was best exemplified in the case of Black female targets that were less likely to be perceived in gender stereotypic ways across the life span. We suggest stereotype research needs to shift to accommodate for the complexity and diversity of real people.

    Full Text Available The aim of this study is to verify the current anthropometrical status of the pupils of the age 12, as well as to compare it with the standards of raising in accordance with the WHO standards. In the study were included 62 pupils (42 male and 20 female. The anthropometric tests were done in height, weight, biacromial and elbow breadth, subcutaneous adipose tissue at the : suprailiac skinfold; subscapular skinfold; triceps skinfold, as well as the abdominal circumference. The results showed that there was a heterogenic distribution of results, especially in the body weight, where the distribution between the minimal and maximal results is 28-70 kg, with the average 43, 14 ± 9, 78 of standard deviation with the male pupils, while with the female pupils was noticed more homogenous group and the standard deviation was significantly lower than with the female pupils in all variables. The findings show that almost in all measured variables female pupils are more developed at this age, especially the body high, body weight and subcutaneous adipose tissue, while as regards the abdominal circumference and body breadth, the male pupils are more developed. Comparison of symbolic sample of this research with the WHO data shows an approximate trend of raising and development of children which were included in this research, and the difference is as follows: Female pupils age 12, body height=151.97 cm

    Full Text Available Aging alters brain structure and function. Personal health markers and modifiable lifestyle factors are related to individual brain aging as well as to the risk of developing Alzheimer’s disease (AD. This study uses a novel magnetic resonance imaging (MRI-based biomarker to assess the effects of 17 health markers on individual brain aging in cognitively unimpaired elderly subjects. By employing kernel regression methods, the expression of normal brain-aging patterns forms the basis to estimate the brain age of a given new subject. If the estimated age is higher than the chronological age, a positive brain age gap estimation (BrainAGE score indicates accelerated atrophy and is considered a risk factor for developing AD. Within this cross-sectional, multi-center study 228 cognitively unimpaired elderly subjects (118 males completed an MRI at 1.5T, physiological and blood parameter assessments. The multivariate regression model combining all measured parameters was capable of explaining 39% of BrainAGE variance in males (p < 0.001 and 32% in females (p < 0.01. Furthermore, markers of the metabolic syndrome as well as markers of liver and kidney functions were profoundly related to BrainAGE scores in males (p < 0.05. In females, markers of liver and kidney functions as well as supply of vitamin B12 were significantly related to BrainAGE (p < 0.05. In conclusion, in cognitively unimpaired elderly subjects several clinical markers of poor health were associated with subtle structural changes in the brain that reflect accelerated aging, whereas protective effects on brain aging were observed for markers of good health. Additionally, the relations between individual brain aging and miscellaneous health markers show gender-specific patterns. The BrainAGE approach may thus serve as a clinically relevant biomarker for the detection of subtly abnormal patterns of brain aging probably preceding cognitive decline and development of AD.

    Oudshoorn, Nelly; Neven, Louis; Stienstra, Marcelle

    2016-01-01

    This article adopts an intersectional approach to investigate how age, gender, and diversity are represented, silenced, or prioritized in design. Based on a comparative study of design practices of information and communication technologies (ICTs) for young girls and older people, this article describes differences and similarities in the ways in which designers tried to cope with diversity. Ultimately diversity was neglected, and the developers relied on hegemonic views of gender and age, constructed older people and young girls as an "other," and consequently their input was neglected. These views were thus materialized in design and reinforce such views in powerful yet unobtrusive ways.

    Full Text Available PURPOSES: To assess the risk factors of age-related macular degeneration in Argentina using a case-control study. METHODS: Surveys were used for subjects' antioxidant intake, age/gender, race, body mass index, hypertension, diabetes (and type of treatment, smoking, sunlight exposure, red meat consumption, fish consumption, presence of age-related macular degeneration and family history of age-related macular degeneration. Main effects models for logistic regression and ordinal logistic regression were used to analyze the results. RESULTS: There were 175 cases and 175 controls with a mean age of 75.4 years and 75.5 years, respectively, of whom 236 (67.4% were female. Of the cases with age-related macular degeneration, 159 (45.4% had age-related macular degeneration in their left eyes, 154 (44.0% in their right eyes, and 138 (39.4% in both eyes. Of the cases with age-related macular degeneration in their left eyes, 47.8% had the dry type, 40.3% had the wet type, and the type was unknown for 11.9%. The comparable figures for right eyes were: 51.9%, 34.4%, and 13.7%, respectively. The main effects model was dominated by higher sunlight exposure (OR [odds ratio]: 3.3 and a family history of age-related macular degeneration (OR: 4.3. Other factors included hypertension (OR: 2.1, smoking (OR: 2.2, and being of the Mestizo race, which lowered the risk of age-related macular degeneration (OR: 0.40. Red meat/fish consumption, body mass index, and iris color did not have an effect. Higher age was associated with progression to more severe age-related macular degeneration. CONCLUSION: Sunlight exposure, family history of age-related macular degeneration, and an older age were the significant risk factors. There may be other variables, as the risk was not explained very well by the existing factors. A larger sample may produce different and better results.

    2016-01-01

    Recent studies have demonstrated gender and cultural differences in the recognition of emotions in facial expressions. However, most studies were conducted on American subjects. In this pa- per, we explore the generalizability of several findings to a non-American culture in the form of Danish...... subjects. We conduct an emotion recognition task followed by two stereotype question- naires with different genders and age groups. While recent findings (Krems et al., 2015) suggest that women are biased to see anger in neutral facial expressions posed by females, in our sample both genders assign higher...... ratings of anger to all emotions expressed by females. Furthermore, we demonstrate an effect of gender on the fear-surprise-confusion observed by Tomkins and McCarter (1964); females overpredict fear, while males overpredict surprise....

    2016-10-01

    Takotsubo syndrome (TTS) occurs predominantly in elderly females but young individuals and children may also be affected. There are no consistent differences between men and women regarding age, symptoms, prehospital delay, or clinical course. Mortality has been reported to be higher in males. The QTc interval may be disproportionately prolonged in male patients in the days after admission predisposing them to ventricular arrhythmias. The higher level of cardiac markers in males with TTS may be related to the greater frequency of physical stress before the onset of TTS. Understanding the pathogenetic background may lead to preventive/therapeutic means against this life-threatening disease. Copyright © 2016 Elsevier Inc. All rights reserved.

    In this study, we investigated gender differences in age-related declines in regional cerebral glucose metabolism using FDG-PET in a large population sample with a broad age range. 230 healthy subjects (90 male; age: 34-80 y, 140 females; age: 33-82 y) participated. Correlation maps showing age related declines in glucose uptake were created separately for each gender in SPM2. Using population-based probabilistic volume of interests (VOIs), VOIs were defined for the regions showing significant decline with aging. Age related declines were separately assessed within each age range using analysis of covariate in SPSS 13.0. In the total population without gender effect, age-related negative correlation of glucose metabolism was found in the bilateral inferior frontal gyri, bilateral caudate, bilateral thalamus, left insula, left superior frontal gyrus, left uncus, right superior temporal gyrus, right medial frontal gyrus, right parahippocampal gyrus, right anterior cingulate gyrus (P < 0.001 corrected, extent threshold k = 100). 14 VOIs values of brain regions were calculated based on this negative correlation results. The rate of decline across all defined VOIs assessed in the age category of 'more than 70' referenced to the category of '30- 39years' were 7.85% in the entire sample; 7.62% in male and 8.09% in female. Detailed analyses of declines in each age range showed separable patterns of declines across gender. In males, greater decline was observed after the age 60 (20.45%) than the ages of 30 and 50(7.98%). Whereas in females, greater declines were found in age 60s (20.15%) compared to 50s, and in 40(14.84%) compared to 30s. Age-related decline in cerebral glucose metabolism was found in both genders. We further observed that males show a relatively constant pattern of decline across a life span; whereas, females show a pattern of steep changes aging to 60s and to 40s, which may be related to changes in sex hormone levels after menopause.

    Recurrent genomic imbalances at 16p11.2 are genetic risk factors of variable penetrance for developmental delay and autism.Recently,16p11.2 (chr16:29.5 Mb-30.1 Mb) deletion has also been detected in individuals with early-onset severe obesity.The penetrance of 16p11.2deletion as a genetic risk factor for obesity is unknown.We evaluated the growth and body mass characteristics of 28 individuals with 16p11.2(chr16:29.5 Mb-30.1 Mb) deletion originally ascertained for their developmental disorders by reviewing their medical records.We found that nine individuals could be classilied as obese and six as overweight.These individuals generally had early feeding and growth difficulties,and started to gain excessive weight around 5-6 years of age.Thirteen out of the 18 deletion carriers aged 5 years and older (72%) were overweight or obese,whereas only two of 10 deletion carriers (20%) younger than five were overweight or obese.Males exhibited more severe obesity than females.Thus,the obesity phenotype of 16p11.2 deletion carriers is of juvenile onset,exhibited an age.and gender-dependent penetrance.16p11.2 deletion appears to predispose individuals to juvenile onset obesity and in this case are similar to the well-described Prader-Willi syndrome (PWS).Early detection of this deletion will provide opportunity to prevent obesity.

    In developed countries, systolic blood pressure is known to increase with age. Metabolic risks may generally worse with increasing age. But this trend may be modified by environmental factors which are different between gender and generation. The aim of this study was to examine the relationship between age and gender-related difference in cardio-metabolic risks and life style factors in the Japanese general population. We studied 3628 inhabitants of Watari (mean age 63.9 yrs, 42.5% men), Miyagi prefecture, who participated in a health check-up in 2009. Anthropometry, sitting blood pressures, fasting blood samples were examined. Unhealthy dietary behaviors (night meal, late dinner, fast eating, skipping breakfast, smoking, heavy drinking, lack of regular exercise) were evaluated by standard questionnaire. Presence or absence of each behavior was scored 0 or 1 and total score was calculated as healthy life style score (range 0 to 7, higher the better). Gender difference in age-related changes in blood pressures, BMI, lipid and glucose metabolism were examined by two way ANOVA. Systolic blood pressure was continuously increased from age 30 s to 70 s in both genders. Systolic blood pressure was significantly higher in men than in women in age 30 s (122.0 ± 13.9 vs. 113.3 ± 12.8 mmHg, p < 0.001) but the difference decreased with an increase in age. Similar gender interaction was observed for diastolic blood pressure, BMI, triglyceride and high density lipoprotein (all p < 0.001) but was not for HbA1c. The healthy life style score was lowest in men age 30 s (5.1 ± 1.5) and it increased with an increase in age. Women demonstrated significantly higher healthy life style score than men in all generations. The gender difference in the score was largest in age 30 s and decreased with an increase in age. Cardio-metabolic risks are worse in men than in women in young generation but this gender difference diminishes with age. The gender

    Full Text Available The purpose of this paper is to provide an overview of the phenomenon of increasing gender inequalities that happen at old age regarding women’s pension. Moving from recent life-course theories and studies, this study analyzes the reasons behind gender-biased pension levels and how their cumulative effects result in (continuous significant gender gaps. The article presents a European overview of pension gender gap, focusing on family and work-life issues in Italy. This is one of the first critical reviews of the small but growing literature and national data concerning the effect of gender inequalities related to pension gaps in Italy. In the past, research on the balance of welfare provision between State, family, and market has ignored gender, while more recent studies have barely explored how gender roles, changing over time, interact with the shifts in pension policies. Considering the effects of work-life balance policies since the 2000 Lisbon agenda process and its development, the study especially focuses on the Italian case within the European context. The article examines how the choices in work-life balance policies vary between different national contexts and welfare regimes, by highlighting the Italian case. In this country, welfare and social policy regimes remain very unbalanced, showing a lack of awareness of family and women’s needs, as in many Southern countries, and Italy is not able to give appropriate answers to these problems and to the question of the growing gender gap. This article finally shows the poignancy of structural and cultural reasons for gender differentiated pension levels in Italy, within the European context, according to patterns of employment, marital, and maternal status between earlier and later generations of women.

    Analysing the relationship between gender and memory, and examining the effects of age on the overall memory-related functioning, are the ongoing goals of psychological research. The present study examined gender and age group differences in episodic memory with respect to the type of task. In addition, these subgroup differences were also analysed in visual working memory. A sample of 366 women and 330 men, aged between 16 and 69 years of age, participated in the current study. Results indicate that women outperformed men on auditory memory tasks, whereas male adolescents and older male adults showed higher level performances on visual episodic and visual working memory measures. However, the size of gender-linked effects varied somewhat across age groups. Furthermore, results partly support a declining performance on episodic memory and visual working memory measures with increasing age. Although age-related losses in episodic memory could not be explained by a decreasing verbal and visuospatial ability with age, women's advantage in auditory episodic memory could be explained by their advantage in verbal ability. Men's higher level visual episodic memory performance was found to result from their advantage in visuospatial ability. Finally, possible methodological, biological, and cognitive explanations for the current findings are discussed.

    Denture-related stomatitis is a disorder that often affects denture wearers. The purpose of this study was to evaluate the intensity, genera, and frequency of yeasts in the oral cavity of complete denture wearers in terms of subject gender and age. Nine hundred twenty patients (307 males and 613 females) with complete upper dentures were selected for the study and divided into four age groups: ≤50 years, 51-60, 61-70, and >70 years. Yeast samples were taken as a smear from the palate. The data were collected from January 15, 2007 to January 15, 2012. The distribution of the number of yeast colonies by gender was statistically significant (P=0.02). Across all subjects, there was a statistically significant relationship between the intensity of yeast growth and the gender (P=0.01). In every age group, the number of infection-free individuals was greater among males than females. Intermediate, intense, and abundant growth of yeast occurred most frequently in the youngest group of females. The genera of Candida species and the frequency of yeast infection in denture wearers appear to be influenced by both age and gender. The complete denture wearers ≤50 years of age appeared to have the greatest proclivity to oral Candida infections.

    Full Text Available Emotional expression is the lifeblood of any organization or community. This study provides a particular focus on how organizational work commitment and performance is gendered and emotionalized. This study investigated what impact gender have on employee emotions for employee well-being. Work commitment research has also not adequately addressed the importance of emotions as part of Commitment. It is this lack of attention to the importance of the relationships between gender and emotions and their impact on work commitment, and how this relationship is understood from the perspective of organizational members that underpins the need for research in this area. The research is also based on age acting as a moderator in the relationship of gender and emotion. Recent research investigating emotion in old age suggests that autonomic responsiveness diminishes with age. The experiential aspects of emotion, however, show less marked age differences. As concerned to the emotional expressions research seems to suggest that older adults are better than younger adults at regulating socially-relevant emotional information, older adults are not affected by negative emotions as much as younger counterparts. With age comes the ability to better regulate emotions in order to not disrupt performance on a memory-intensive task. Future studies should also be conducted to determine exactly how older adults achieved the same emotion-regulatory goal with less cognitive effort.

    Violent behaviour associated with alcohol consumption is frequently reported by different media. Clinical data analysing the correlation between alcohol intoxication, age, gender and violence are scarce. The aim of this study was to evaluate the influence of age, gender and blood alcohol content on violent behaviour under the influence of alcohol under central European conditions. Three hundred patients admitted to the emergency department were included into this study in the time period from January 01. to December 31. 2009. The inclusion criteria were a blood alcohol content (BAC) of ≥10 mmol/l, any traumatic injury and an age ≥16 years. Violence was defined as an evitable act committed by others leading to patient's hospitalisation. The data were compared with Wilcoxon and χ2-test for proportions. The data were considered as significant if pviolence with no correlation to blood alcohol content found. Logistic regression analysis revealed male gender and young age as an independent predictor for violence. These results clarify the relationship between alcohol, age, gender and violence and have important implications for municipal-level alcohol policies.

    Regional cerebral blood flow (rCBF) is a useful surrogate marker of neuronal activity and a parameter of primary interest in the diagnosis of many diseases. The increasing use of mouse models spawns the demand for in vivo measurement of rCBF in the mouse. Small animal SPECT provides excellent spatial resolution at adequate sensitivity and is therefore a promising tool for imaging the mouse brain. This study evaluates the feasibility of mouse brain perfusion SPECT and assesses the regional pattern of normal Tc-99m-HMPAO uptake and the impact of age and gender. Whole-brain kinetics was compared between Tc-99m-HMPAO and Tc-99m-ECD using rapid dynamic planar scans in 10 mice. Assessment of the regional uptake pattern was restricted to the more suitable tracer, HMPAO. Two HMPAO SPECTs were performed in 18 juvenile mice aged 7.5 ± 1.5weeks, and in the same animals at young adulthood, 19.1 ± 4.0 weeks (nanoSPECT/CTplus, general purpose mouse apertures: 1.2kcps/MBq, 0.7mm FWHM). The 3-D MRI Digital Atlas Database of an adult C57BL/6J mouse brain was used for region-of-interest (ROI) analysis. SPECT images were stereotactically normalized using SPM8 and a custom made, left-right symmetric HMPAO template in atlas space. For testing lateral asymmetry, each SPECT was left-right flipped prior to stereotactical normalization. Flipped and unflipped SPECTs were compared by paired testing. Peak brain uptake was similar for ECD and HMPAO: 1.8 ± 0.2 and 2.1 ± 0.6 %ID (p=0.357). Washout after the peak was much faster for ECD than for HMPAO: 24 ± 7min vs. 4.6 ± 1.7h (p=0.001). The general linear model for repeated measures with gender as an intersubject factor revealed an increase in relative HMPAO uptake with age in the neocortex (p=0.018) and the hippocampus (p=0.012). A decrease was detected in the midbrain (p=0.025). Lateral asymmetry, with HMPAO uptake larger in the left hemisphere, was detected primarily in the neocortex, both at juvenile age (asymmetry index AI=2.7 ± 1

    Full Text Available Abstract Background Hospitalization for heart failure (HF is associated with high-in-hospital and short- and long-term post discharge mortality. Age and gender are important predictors of mortality in hospitalized HF patients. However, studies assessing short- and long-term risk of death stratified by age and gender are scarce. Methods A nationwide cohort was identified (ICD-9 codes 402, 428 and followed through linkage of national registries. The crude 28-day, 1-year and 5-year mortality was computed by age and gender. Cox regression models were used for each period to study sex differences adjusting for potential confounders (age and comorbidities. Results 14,529 men, mean age 74 ± 11 years and 14,524 women, mean age 78 ± 11 years were identified. Mortality risk after admission for HF increased with age and the risk of death was higher among men than women. Hazard ratio's (men versus women and adjusted for age and co-morbidity were 1.21 (95%CI 1.14 to 1.28, 1.26 (95% CI 1.21 to 1.31, and 1.28 (95%CI 1.24 to 1.31 for 28 days, 1 year and 5 years mortality, respectively. Conclusions This study clearly shows age- and gender differences in short- and long-term risk of death after first hospitalization for HF with men having higher short- and long-term risk of death than women. As our study population includes both men and women from all ages, the estimates we provide maybe a good reflection of 'daily practice' risk of death and therefore be valuable for clinicians and policymakers.

    Impulsivity is frequently included as a risk factor in models of adolescent sexual risk-taking; however, findings on the magnitude of association between impulsivity and risky sexual behavior are variable across studies. The aims of the current meta-analysis were to examine (1) how specific impulsivity traits relate to specific risky sexual behaviors in adolescents, and (2) how the impulsivity-risky sex relationship might differ across gender, age, and race. Eighty-one studies were meta-analyzed using a random effects model to examine the overall impulsivity-risky sex relationship and relationships among specific impulsivity traits and risky sexual behaviors. Overall, results revealed a significant, yet small, association between impulsivity and adolescent risky sexual behavior (r=0.19, psexual behaviors as compared to negative outcomes related to these behaviors. Gender moderated the overall relationship (β=0.22, p=0.04), such that effect sizes were significantly larger in samples with more females. Age, race, study design, and sample type did not moderate the relationship, although there was a pattern suggesting smaller effects for adolescents in juvenile detention settings. Adolescent samples with more females showed a larger impulsivity-risky sex relationship, suggesting that impulsivity may be a more important risk factor for risky sex among adolescent females. Research and treatment should consider gender differences when investigating the role of impulsivity in adolescent sexual risk-taking. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The assessment of exposure to ionizing radiation, carried out long time after exposure, is currently performed by scoring of translocations, a specific type of chromosomal aberrations. The translocations rate observed in peripheral blood lymphocytes of exposed subjects is compared to that observed in a control population. However, the translocation specificity towards radiation exposure is not clearly identified. To avoid any hasty conclusion, it is necessary to identify all the factors likely to induce translocation. To our knowledge, no study has thus far examined the effects of all these different factors on translocation rates. A review of the literature thus allowed us to assess the impact of host factors and lifestyle on the production of translocations. This study confirms that age appears to be the factor having the greatest impact on the rate of translocations, especially over 60 years. To date, the factor 'age' is already considered in estimating the impact of radiation on the rate of translocation for all age groups. However, the study also shows that this rate varies significantly when the patient is exposed simultaneously and significantly towards many lifestyle agents. A precise threshold translocation rate should thus be established as a function of known behavioral exposures, below which it is impossible to conclude that radiological exposure has occurred. The effects of chemicals on the translocation rate after occupational exposure will be the subject of a second part. (authors)

    Full Text Available This study investigated the relationship between pre-competition mood state factors in gymnastics by gender, age and a national ranking. Participant-gymnasts (total n=116, male n=49, female n=67 completed a Brunel Mood Scale (BRUMS one day prior to their main competition of the year. Information was also gathered from gymnasts of gender, age and a national ranking. Consistent with theoretical predictions, results confirmed that a number of pre-competition mood states differed by age with both juniors and seniors having a higher level of anger than children (p<.05 respectively. Also, seniors demonstrated higher tension than children (p<.001. However, only anger showed significant differences by gender with male gymnasts demonstrating higher levels of anger than female gymnasts (p<.05, and with international gymnasts registering higher levels of anger compared with second class gymnasts (p<.05. Authors suggest that future research should investigate relationships between the pre-competition mood in other gymnastics-related disciplines and sports, as well as competitive performances.

    To analyse time trends in self-rated health in older people by gender and age and examine disability in the time trends of self-rated health. The data used come from the Spanish National Health Surveys conducted in 2001, 2003, 2006 and 2011-12. Samples of adults aged 16 yr and older were selected. Multivariate logistic regression was used to assess the association between age, gender, socio-economic status, marital status, disability and self-rated health across period study. Women exhibited lower (higher) prevalence of good self-rated health (disability) compared to men. The multivariate analysis for time trends found that good self-rated health increased from 2001 to 2012. Overall, variables associated with a lower likelihood of good self-rated health were: being married or living with a partner, lower educational level, and disability. Trends of good self-rated health differ by gender according to socio-demographic factors and the prevalence of disability.

    Having a low level of education has been associated with worse physical performance. However, it is unclear whether this association varies by age, gender or the occupational categories of manual and non-manual work. This study examined whether there are education-related differences across four dimensions of physical performance by age, gender or occupational class and to what extent chronic diseases and lifestyle-related factors may explain such differences. Participants were a random sample of 3212 people, 60 years and older, both living in their own homes and in institutions, from the Swedish National Study on Aging and Care, in Kungsholmen, Stockholm. Trained nurses assessed physical performance in grip strength, walking speed, balance and chair stands, and gathered data on education, occupation and lifestyle-related factors, such as physical exercise, body mass index, smoking and alcohol consumption. Diagnoses of chronic diseases were made by the examining physician. Censored normal regression analyses showed that persons with university education had better grip strength, balance, chair stand time and walking speed than people with elementary school education. The differences in balance and walking speed remained statistically significant (p models. Further analyses stratified by gender and occupational class suggested that the education-related difference in grip strength was only evident among female manual workers, while the difference in balance and walking speed was only evident among female and male non-manual workers, respectively. Higher education was associated with better lower extremity performance in people aged 60 to 80, but not in advanced age (80+ years). Our results indicate that higher education is associated with better grip strength among female manual workers and with better balance and walking speed among female and male non-manual workers, respectively.

    The authors used a representative national sample (N = 777) to test the evolutionary hypothesis that men would be more bothered by sexual infidelity and women by emotional infidelity, the Jealousy as a Specific Innate Module (JSIM) effect. Our alternative conceptualization of jealousy suggests that there are distinct emotional components of jealousy that did not evolve differently by gender. The authors looked for effects of age, socioeconomic status (SES), and type of measure (continuous or dichotomous) on jealousy. The authors did not find age or SES effects. Forced-choice items provided support for our alternative view; both genders showed more anger and blame over sexual infidelity but more hurt feelings over emotional infidelity. Continuous measures indicated more emotional response to sexual than emotional infidelity among both genders.

    The aim of this paper is to make a descriptive analysis of Problematic Internet Use in college students, evaluating the possible association with health problems and addictive behaviors, as well as gender differences in user types. A total of 2,780 students participated in the study between 2011 and 2014, 29% of them being males (age 20.8 ± 5.1 years) and 71% females (age 20.3 ± 4.4 years). The prevalence of Problematic Internet Use (PIU) assessed by the Internet Addiction Test was 6.08%. Being under 21 years of age and studying for degrees in subjects other than the health sciences were associated factors with a higher frequency of this problem, no differences by gender or type of address were found. The results show a significant association with some health problems (migraines, back pain, excess weight or obesity, insufficient rest), psychological aspects (risk of eating disorders, risk of mental disorder, depression), family problems and discrimination; with no associations with substance use (alcohol, cannabis or tobacco) being found. Concerning the time of Internet use, weekly hours were significantly higher in women than in men, both the total time as for leisure. The analysis of the profile use in problematic users revealed that males are related to aspects of entertainment such as games or shopping online and females are related to aspects of socialization, such as chats and social networks.

    This study explored the age-related deterioration in stretch-shortening cycle (SSC) muscle power and concurrent force-velocity properties in women and men across the adult life span. A total of 315 participants (women: n = 188; men: n = 127) aged 18-81 years performed maximal countermovement jumps on an instrumented force plate. Maximal SSC leg extension power expressed per kg body mass (Ppeak) was greater in men than in women across the adult age span (P < 0.001); however, this gender difference was progressively reduced with increasing age, because men showed an ∼50% faster rate of decline in SSC power than women (P < 0.001). Velocity at peak power (VPpeak) was greater in men than in women (P < 0.001) but declined at a greater rate in men than in women (P = 0.002). Vertical ground reaction force at peak power (FPpeak) was higher in men than in women in younger adults only (P < 0.001) and the age-related decline was steeper in men than in women (P < 0.001). Men demonstrated a steeper rate of decline in Ppeak than women with progressive aging. This novel finding emerged as a result of greater age-related losses in men for both force and velocity. Consequently, maximal SSC power production was observed to converge between genders when approaching old age.

    2014-01-01

    AgeFactDB (http://agefactdb.jenage.de) is a database aimed at the collection and integration of ageing phenotype data including lifespan information. Ageing factors are considered to be genes, chemical compounds or other factors such as dietary restriction, whose action results in a changed lifespan or another ageing phenotype. Any information related to the effects of ageing factors is called an observation and is presented on observation pages. To provide concise access to the complete information for a particular ageing factor, corresponding observations are also summarized on ageing factor pages. In a first step, ageing-related data were primarily taken from existing databases such as the Ageing Gene Database—GenAge, the Lifespan Observations Database and the Dietary Restriction Gene Database—GenDR. In addition, we have started to include new ageing-related information. Based on homology data taken from the HomoloGene Database, AgeFactDB also provides observation and ageing factor pages of genes that are homologous to known ageing-related genes. These homologues are considered as candidate or putative ageing-related genes. AgeFactDB offers a variety of search and browse options, and also allows the download of ageing factor or observation lists in TSV, CSV and XML formats. PMID:24217911

    The increasing dispensing of statins has raised concern about the appropriateness of prescribing to various population groups. We aimed to (1) investigate incident and prevalent statin prescribing according to indication, gender and age and (2) relate prescribing patterns to evidence on beneficial and adverse effects. A cohort of Danish inhabitants (n = 4 424 818) was followed in nationwide registries for dispensed statin prescriptions and hospital discharge information. We calculated incidence rates (2005-2009), prevalence trends (2000-2010) and absolute numbers of statin users according to register proxies for indication, gender and age. In 2010, the prevalence became highest for ages 75-84 and was higher in men than women (37% and 33%, respectively). Indication-specific incidences and prevalences peaked at ages around 65-70, but in myocardial infarction, the prevalence was about 80% at ages 45-80. Particularly, incidences tended to be lower in women until ages of about 60 where after gender differences were negligible. In asymptomatic individuals (hypercholesterolaemia, presumably only indication) aged 50+, dispensing was highest in women. The fraction of statin dispensing for primary prevention decreased with age: higher for incident than prevalent prescribing. Independent of age, this fraction was highest among women, e.g. 60% versus 45% at ages 55-64. The fraction for potential atherosclerotic condition (PAC, e.g. heart failure) increased with age. Prevalence of statin utilization was highest for ages 75-84, although indication-specific measures were relatively low. Despite inconclusive evidence for a favourable risk-benefit balance, statin prescribing was high among people aged 80+, asymptomatic women and PAC patients. © 2015 John Wiley & Sons, Ltd.

    The influence of age and gender in the electrical charge delivered in a given population was analysed using an electroconvulsive therapy (ECT) clinical database. An observational, prospective, longitudinal study with descriptive analysis was performed using data from a database that included total bilateral frontotemporal ECT carried out with a Mecta spECTrum 5000Q(®) in our hospital over 6 years. From 2006 to 2012, a total of 4,337 ECT were performed on 187 patients. Linear regression using mixed effects analysis was weighted by the inverse of the number of ECT performed on each patient per year of treatment. The results indicate that age is related with changes in the required charge (P=.031), as such that the older the age a higher charge is needed. Gender is also associated with changes in charge (P=.014), with women requiring less charge than men, a mean of 87.3mC less. When the effects of age and gender are included in the same model, both are significant (P=.0080 and P=.0041). Thus, for the same age, women require 99.0mC less charge than men, and in both genders the charge increases by 2.3mC per year. From our study, it is concluded that the effect of age on the dosage of the electrical charge is even more significant when related to gender. It would be of interest to promote the systematic collection of data for a better understanding and application of the technique. Copyright © 2015 SEP y SEPB. Publicado por Elsevier España, S.L.U.

    Highlights: • An effect of gender and age structure on municipal waste generation was presented. • The waste accumulation index is influenced by a number of unemployed women. • Greater share of women in society contributes to greater waste production. • A model describing the analyzed dependences was determined. - Abstract: In this study the effect of gender and age structure on municipal waste generation was investigated. The data from 10-year period, from 2001 to 2010 year, were taken into consideration. The following parameters of gender and age structure were analyzed: men and woman quantity, female to male ratio, number of working, pre-working and post-working age men/women, number of unemployed men/women. The results have showed a strong correlation of annual per capita waste generation rate with number of unemployed women (r = 0.70) and female to male ratio (r = 0.81). This indicates that waste generation rate is more depended on ratio of men and women that on quantitative size of each group. Using the regression analysis a model describing the dependence between female to male ratio, number of unemployed woman and waste quantity was determined. The model explains 70% of waste quantity variation. Obtained results can be used both to improve waste management and to a fuller understanding of gender behavior.

    To examine the relationships between physical function and gender-stereotyped traits and whether these relationships are modified by sex or social context. A total of 1995 community-dwelling older adults from the International Mobility in Aging Study (IMIAS) aged 65 to 74 years were recruited in Natal (Brazil), Manizales (Colombia), Tirana (Albania), Kingston (Ontario, Canada), and Saint-Hyacinthe (Quebec, Canada). We performed a cross-sectional analysis. Study outcomes were mobility disability, defined as having difficulty in walking 400 meters without assistance or climbing a flight of stairs without resting, and low physical performance, defined as a score gender roles (Masculine, Feminine, Androgynous, and Undifferentiated) using site-specific medians of femininity and masculinity as cut-off points. Poisson regression models were used to estimate prevalence rate ratios (PRR) of mobility disability and poor physical performance according to gender roles. In models adjusted for sex, marital status, education, income, and research site, when comparing to the androgynous role, we found higher prevalence of mobility disability and poor physical performance among participants endorsing the feminine role (PRR = 1.20, 95% confidence interval (CI) 1.03-1.39 and PRR = 1.37, CI 1.01-1.88, respectively) or the undifferentiated role (PRR = 1.23, 95% CI 1.07-1.42 and PRR = 1.58, CI 1.18-2.12, respectively). Participants classified as masculine did not differ from androgynous participants in prevalence rates of mobility disability or low physical performance. None of the multiplicative interactions by sex and research site were significant. Feminine and undifferentiated gender roles are independent risk factors for mobility disability and low physical performance in older adults. Longitudinal research is needed to assess the mediation pathways through which gender-stereotyped traits influence functional limitations and to investigate the longitudinal nature of these

    Blood pressure and total peripheral resistance increase with age. However, the effect of age on vasodilatory capacity has not been characterized. To delineate the effects of aging, gender, and physical training on peripheral vascular function, we measured blood pressure during submaximal and maximal treadmill exercise and measured blood pressure, calf blood flow, and calf conductance (blood flow/mean blood pressure) at rest and during maximal hyperemia in 58 healthy sedentary subjects (men aged 25 +/- 5 and 65 +/- 3 years and women aged 27 +/- 5 and 65 +/- 4 years) and in 52 endurance exercise-trained subjects (men aged 30 +/- 3 and 65 +/- 4 years and women aged 27 +/- 3 and 65 +/- 3 years). Systolic and mean blood pressures were higher at rest, during maximal calf hyperemia, and during submaximal exercise of the same intensity in the older than in the younger subjects of the same gender and exercise training status (p less than 0.01). The magnitude of the age-related effect on blood pressure during exercise was greater in women than in men (p less than 0.01). Diastolic blood pressure during submaximal exercise was also higher in the older than in the younger subjects (p less than 0.05) but not in women treated with estrogen replacement. In contrast, systolic and mean blood pressures during submaximal work were lower in physically conditioned subjects than in sedentary age- and gender-matched subjects (p less than 0.05) but not in older women. Increased age was associated with reduced maximal calf conductance in women (p less than 0.01) but not in men. However, calf vasodilatory capacity was higher in trained than in untrained subjects (p less than 0.01), regardless of age and gender. There was a significant inverse relation between maximal calf conductance and systolic, diastolic, and mean blood pressures during submaximal exercise (r = -0.31 to -0.53, p less than 0.01) and a direct relation between maximal calf conductance and maximal oxygen uptake (r = 0.66, p

    Full Text Available This paper analyzes the changes of population by age and the gender structure in the regions of the Republic of Macedonia. Age and gender is very important not only for the development of demographic process but also for the development of regions. They play an important role in planning the health care needs and other services with the socio-economic and cultural character. In this sense they affect the performance of demographic processes (births, deaths, marriages, etc. and are a result of bilateral relations fertility, mortality, migration movements and other social processes. The main objective of this paper is to identify the aging phenomenon of population in state level and regions. This paper also dedicates special importance to the changes of age and sex structure, during the period between1981-2014 in the regions of the republic of Macedonia.

    This is a bibliographic study in which a research of scientific production regarding to Woman in the Third Age was proceeded, analizing the catalogue of Dissertations and Thesis of the Center of Studies and Researches in Nursing (CEPEn) of the Brazilian Association of Nursing (ABEn) available in CD-ROM, comprising the period from 1979 to 1999. The objective was to know the removals and approaches in nursing knowledge concerning the study object from the doctorate thesis "The ageing women's knowledge and health practices in gender perspective". It was concluded that the issue of woman in the third age was investigated in few studies. In addition, those researches' objects was strongly removed from gender issues, demonstrating that sexual approach of ageing was out of consideration, as well as denial of woman's social roles.

    Full Text Available The present study aimed to assess the effect of age and gender on second-grade children’s reading performance. Two hundred and eighty-seven children aged 7.1–8.2 years were divided into two age subgroups (the younger, 85–91 months and the older, 92–98 months and were examined in reading accuracy, fluency, and comprehension tasks. Results showed a significant effect of age in reading performance, with the older children having better scores than younger ones for reading fluency, reading comprehension, and the total reading performance. Gender was not found to play an important role in reading performance. The findings are discussed on the ground of functional brain development and the different rates of cerebral maturation.

    The purpose of the study was to examine whether gender differences exist in the mean levels of and relations between adolescents' home environments (parents' view of science, socio-economic status (SES)), motivations (intrinsic and instrumental motivations, self-beliefs), and pursuit of science careers. For the purpose, the Programmed for International Student Assessment 2006 data of Korean 15-year-old students were analysed. The results of the study showed that girls had lower levels of science intrinsic and instrumental motivations, self-beliefs, and science-career pursuit (SCP) as well as their parents' values in science less than boys. Gender similarities, rather than gender differences, existed in patterns of causal relationship among home environments, motivations, and SCP. The results showed positive effects for parents' higher value in science and SES on motivations, SCP, and for intrinsic and instrumental motivations on SCP for girls and boys. These results provide implications for educational interventions to decrease gender differences in science motivations and SCP, and to decrease adolescents' gender stereotypes.

    Full Text Available Background/Aim. World Health Organization (WHO in its plan for health policy until the year 2010, has taken reduction of risk factors of suicide as its 12th aim. Because of the fact that the problem of suicide is also significant health problem in our society, the aim of this study was to examine the influence of life period as a risk factor for suicide in the area of the town of Kragujevac. Methods. In total 211 persons, both sexes, aged between 17 and 91 years, from the area of the town of Kragujevac, who had been committed a suicide during the period from 1996 to 2005, were included in a retrospective study. This study included the analysis of: conditions prior to suicide, locations of suicide, motives for suicide, the ways of committing suicide. For statistical analysis χ2 test and univariante regression model were used. Results. Average rate of suicide, in analyzed period, moved from 8.7 to 27 with a mean value of 14.6± 6.9. Suicide rates were the lowest in the age group from 15 to 24 years and the highest in the age group above 65 years (p < 0.05. Among the presuicidal conditions, within any age groups the presence of mental disease dominated as a factor for suicide, but within the oldest one in which organic diseases prevailed as a factor for suicide (p < 0.05. Statistically significant fact is that a house (flat was the main location for committing suicide in any age groups. Motives for suicide were significantly different within the groups and they were mostly unknown. Committing suicide by hanging was the most frequent way of suicide among any age groups. Univariant regression analysis failed to show any impact of age on the analyzed factors. Conclusion. Because of the fact that an average rate of suicide in elderly increases it is obligatory to primarily determine risk factors for suicide among people more than 65 years of age. Physicians should play the most important role in that.

    The effects of aging and gender on the neurochemistry of the dopaminergic system have been studied extensively; however, data on comparative behavioral consequences of lesions of the dopaminergic system in aging and in female animals are limited. This study presents experimental results on the behavioral and morphological outcome in young, aging, and gonadectomized male and female rats in the 6-OHDA model of Parkinson's disease. Both young and aging male animals were more susceptible to 6-OHDA than females: female rats had significantly less dopaminergic cell loss and showed a higher degree of behavioral recovery. Although the dopaminergic cell loss was only slightly more in the aging rats of the same sex, they showed more severe behavioral deficits in both gender groups. Ovariectomy did not significantly influence the dopaminergic cell loss, but behavioral recovery was worse when compared to non-ovariectomized females. In contrast, castrated males had significantly less dopaminergic cell loss than non-castrated males, but the behavioral recovery was not significantly better. The obtained results are discussed in light of the available literature on the age and gender differences in animals models of Parkinson's disease.

    There is increased interest in the role that ethnicity, sociocultural factors, and gender play in research, health care delivery, and response to intervention. The impact of these factors on AIDS awareness programs, on the phenomenology of suicide and anorexia nervosa, and on clinical psychopharmacology in a homogeneous population is discussed. Risky sex practices can be related to cultural norms that stigmatize condom use and sex education; economic deprivation; and male dominance. Gender, cultural, and ethnic demographics can identify high-risk groups as well as influence effective interventions. Suicide rates and risk factors are compared in African-American, Canadian Native, and South Korean adolescents. Academic stress was a differential risk factor for the Koreans. Anorexia nervosa predominantly affects women and has cultural differences in prevalence. The homogeneous population in Hong Kong illustrates the impact of ethnicity, sociocultural factors, and gender on clinical psychopharmacology. Attention to ethnicity, sociocultural factors, and gender can individualize and improve the effectiveness of clinical psychopharmacology.

    The technique of threshold tracking to test axonal excitability gives information about nodal and internodal ion channel function. We aimed to investigate variability of the motor excitability measurements in healthy controls, taking into account age, gender, body mass index (BMI) and small changes in skin temperature. We examined the left median nerve of 47 healthy controls using the automated threshold-tacking program, QTRAC. Statistical multiple regression analysis was applied to test relationship between nerve excitability measurements and subject variables. Comparisons between genders did not find any significant difference (P>0.2 for all comparisons). Multiple regression analysis showed that motor amplitude decreases with age and temperature, stimulus-response slope decreases with age and BMI, and that accommodation half-time decrease with age and temperature. The changes related to demographic features on TRONDE protocol parameters are small and less important than in conventional nerve conduction studies. Nonetheless, our results underscore the relevance of careful temperature control, and indicate that interpretation of stimulus-response slope and accommodation half-time should take into account age and BMI. In contrast, gender is not of major relevance to axonal threshold findings in motor nerves. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Objectives The occurrence and causes of maxillofacial trauma varies in different regions of the world. The aim of this study was to identify the occurrence, types and causes of maxillofacial injuries according to the age and gender differences in patients treated at the Department of Maxillofacial Surgery, University Hospital Center Osijek, between January 2011 and December 2013. Materials and methods A total of 64 patients, 41 males (64.1%) and 23 females (35.9%), aged from 18 to 86 years (mean age 42) participated in the study. Data collected and analyzed included gender, age, cause of injury and the type of maxillofacial injuries. Results The most common cause of injuries in both gender groups was falling down (39% males; 65% females). The second leading cause of injuries in males was interpersonal violence (29%) and in females traffic accident (26%) (p0.05). The most common causes of injuries in the youngest patients was violence (43%), and in others fall (50-70%; p0.05). The majority of the falls and violence caused bone tissue injuries, and soft tissue and dentalveolar injuries were detected in traffic and sports accidents (p>0.05). Conclusion Falling down was the most common cause of oro-maxillofacial injuries in both men and women and in all three age groups. The leading type of injury was bone injury. The data obtained from this study provide important information for future prevention from injuries. PMID:27688419

The aim of this study was to determine to what extent patients with COPD are offered evidence-based interventions and how the interventions are distributed across demographic and clinical factors in the sample. Baseline registrations of demographic, disease-related, and management-related variables of 7,810 patients in the Swedish National Airway Register are presented. One-third of the patients were current smokers. Patient-reported dyspnea and health-related quality of life were more deteriorated in elderly patients and patients living alone. Only 34% of currently smoking patients participated in the smoking cessation programs, and 22% of all patients were enrolled in any patient education program, with women taking part in them more than men. Less than 20% of the patients had any contact with physiotherapists or dieticians, with women having more contact than men. Men had more comorbidities than women, except for depression and osteoporosis. Women were more often given pharmacological treatments. With increasing severity of dyspnea, participation in patient education programs was more common. Dietician contact was more common in those with lower body mass index and more severe COPD stage. Both dietician contact and physiotherapist contact increased with deteriorated health-related quality of life, dyspnea, and increased exacerbation frequency. The present study

    Cognitive impairment is present in up to 65 % of multiple sclerosis (MS) patients. The Brief Repeatable Battery of neuropsychological tests (BRB) is one of the most used neuropsychological tools for cognitive assessment in MS. However, relative lack of normative data limits its application in research and clinical practice. In order to obtain normative data for a Serbian population, we administered the BRB version A to 140 healthy subjects and assessed the influence of demographic factors such as gender, age, and education on the tests' scores. We also calculated corrections for these factors. Higher education was associated with better performance on all the tests. Age influenced all the tests, except the word list generation, higher age being associated with worse performance on all other tests. Women performed worse on the paced auditory serial addition test 2, no other gender differences were observed. Our data obtained for the Serbian population could further improve use of the BRB in clinical practice and for the research purposes, establishing cognitive evaluation as a part of standard neurological examination of MS patients.

    Background: The aim of this study was to estimate the magnitude of gender differences in hazardous drinking among middle-aged people and to analyse whether these differences are associated with contextual factors, such as public policies or socioeconomic factors. Methods: Cross-sectional design. The study population included 50- to 64-year-old residents of 16 European countries who participated in the Survey of Health, Ageing and Retirement in Europe project conducted in 2010–12 (n = 26 017). We estimated gender differences in hazardous drinking in each country. To determine whether different social context or women’s empowerment variables were associated with gender differences in hazardous drinking, we fitted multilevel Poisson regression models adjusted for various individual and country-level variables, which yielded prevalence ratios and their 95% confidence intervals (95% CI). Results: Prevalence of hazardous drinking was significantly higher in men than women [30.2% (95% CI: 29.1–31.4%) and 18.6% (95% CI: 17.7–19.4%), respectively] in most countries, although the extent of these differences varied between countries. Among individuals aged 50–64 years in Europe, risk of becoming a hazardous drinker was 1.69 times higher (95% CI: 1.45–1.97) in men, after controlling for individual and country-level variables. We also found that lower values of the gender empowerment measure and higher unemployment rates were associated with higher gender differences in hazardous drinking. Conclusion: Countries with the greatest gender differences in hazardous drinking were those with the most restrictions on women’s behaviour, and the greatest gender inequalities in daily life. Lower gender differences in hazardous drinking seem to be related to higher consumption among women. PMID:25616593

    Non-medical use (NMU) of prescription opioids in youth is of concern since they may continue this pattern into adulthood and become addicted or divert medications to others. Research into risk factors for NMU can help target interventions to prevent non-medical use of opioids in youth. The National Monitoring of Adolescent Prescription Stimulants Study (N-MAPSS) was conducted from 2008 to 2011. Participants 10-18years of age were recruited from entertainment venues in urban, rural and suburban areas of 10 US cities. Participants completed a survey including questions on their use of prescription opioids. NMU was defined as a non-labeled route of administration or using someone else's prescription. Information on age, gender, alcohol, marijuana and tobacco use was also collected. Summary descriptive, chi-square statistics and logistic regression were conducted using SAS 9.4. Of the 10,965 youth who provided information about past 30day prescription opioid use, prevalence of reported opioid use was 4.8% with 3.2% reported as NMU (n=345) and 1.6% as medical use (MU) only (n=180). More males than females (55.7% vs. 44.4%) reported opioid NMU (p<0.0001). Logistic regression revealed that among males (comparing NMU to MU only), current smokers were 4.4 times more likely to report opioid NMU than non-smokers (95% CI: 1.8, 10.7). Among females (comparing NMU to MU only), current smokers and alcohol users were more likely to report opioid NMU than those who had never smoked or used alcohol (OR=3.2, 95% CI: 1.4, 7.0 and OR=4.1, 95% CI: 1.7, 10.4, respectively). These results suggest that further research on gender differences in opioid NMU is needed; interventions for opioid NMU may need to be gender specific to obtain the best results.

  13. Production activities and economic dependency by age and gender in Europe: A cross-country comparison

    We compare selected European countries using an economic dependency ratio which emphasizes the role of age-specific levels of production and consumption. Our analysis reveals large differences in the age- and gender-specific level and type of production activities across selected European countries and identifies possible strategies to adjust age-specific economic behaviour to an ageing population. The cross-country differences in economic dependency of children and elderly persons are largely determined by the age at which people enter, respectively exit, the labour market. The ability of the working age population to support children and elderly persons in turn is strongly influenced by the participation of women in paid work. We also provide a measure for the age-specific production and consumption in form of unpaid household work. The inclusion of unpaid household work leads to a decrease of the gender differences in production activities and indicates that the working age population supports children and elderly persons not only through monetary transfers but also through services produced by unpaid work (e.g. childcare, cooking, cleaning…). Given the available data, we cannot distinguish the age profile of consumption by gender and have to assume – in case of unpaid work - that each member of the household consumes the same. Hence, our results have to be regarded as a first approximation only. Our paper aims to argue that a reform of the welfare system needs to take into account not only public transfers but also private transfers, in particular the transfers in form of goods and services produced through unpaid household work.

    The exploratory study presented here examines children's ability to recognize another person's need-of-help. This social perception process necessarily precedes the decision to actively help others. Fifty-eight children aged between 5 and 13 completed three experimental paradigms. They were asked to look at black-and-white drawings and to indicate which ones showed somebody in need of help. A control task requiring children to differentiate between pictures of humans and birds measured general categorization abilities. This experimental design enabled us to consider confounding effects of children's developmental status and motivation and to distinguish them from specific need-of-help recognition abilities. As gender and age have been shown to influence social perception as well as helping behavior, we explored whether these factors also have an impact on need-of-help recognition. Children's response accuracies and response times (RTs) were analyzed. We observed clearly higher accuracy rates for younger girls compared to younger boys specifically in the need-of-help recognition tasks. For boys, an age-related performance improvement was found. Younger girls performed at a similarly high level as older girls and boys. No gender differences were observed for children aged over nine. This report provides first evidence that the developmental trajectory of children's ability to recognize another person's need-of-help differs for girls and boys. PMID:24578698

    Full Text Available Background and Objectives: This study was designed to investigate the association of the gender and subtype diagnosis with the onset age of the disease, marriage, reproductive rates in the schizophrenic inpatients. Methods: Total of 463 patients (329 males and 134 females hospitalized with the diagnosis of schizophrenia according to DSM-IV criteria and who were between 15-65 years of age were included in the study. We evaluated the age, gender, marital status, number of children, onset of the disease and subtype of schizophrenia. Results: Mean of onset of the disease score was higher statistically in the females (27.6 ± 4.3 than the males (23.7 ± 3.9 (p < 0.05 in our study. The paranoid subtype was the commonest, while women were more likely to be married than men, men had more children than women; and the paranoid subtype were more likely to be married than the other groups. Conclusions: Onset age of schizophrenia was four years higher in the women than in men and that the rates of the schizophrenia subtypes were consistent with those detected in the other studies demonstrates that these rates were determined by neurobiological mechanisms rather than socio-cultural factors.

    Aim: To investigate the gender differences associated with a thinner intima-media thickness (IMT) of the common carotid artery (CCA) in women. Materials and methods: In a sample of 218 consecutive healthy volunteers comprising 110 men and 108 women, the IMT of the CCA was measured using B-mode ultrasonography. Blood pressure, fasting blood sugar, body mass index (BMI), blood lipid profile, homocysteine, folic acid, uric acid, high sensitive C-reactive protein, and thiobarbituric acid reactive substances (TBARS) levels were measured and compared with each other in both genders. Results: The IMT of the CCA was significantly thinner in women than in men (p = 0.012). Blood pressure, fasting plasma glucose, BMI, low-density lipoprotein cholesterol, triglycerides, homocysteine, uric acid, and TBARS were significantly (p < 0.05) lower, folic acid and high-density lipoprotein cholesterol (HDL-C) were significantly (p < 0.0001) higher in women compared with men. Multivariable logistic regression analysis revealed that higher serum levels of homocysteine, uric acid, and TBARS, and lower serum levels of HDL-C were significantly (p < 0.05) associated with male sex. Multiple linear regression analysis further revealed that age, sex, and BMI were independently associated with CCA IMT. Conclusions: The IMT of the CCA was thinner in women than in men. Traditional vascular risk factors explain only a small amount of variance in multivariate regression models supporting the hypothesis that other behavioural, sex hormone-related or genetic factors, which have not been sufficiently explored so far, may play a role in the gender differences of IMT.

  1. Socio-ecological perspective of older age life expectancy: income, gender inequality, and financial crisis in Europe.

    Population is aging rapidly in Europe. Older age life expectancy (OLE) can be influenced by country-level depth of credit information (DCI) as an indicator of financial crisis, gross national income (GNI) per capita, and gender inequality index (GII). These factors are key indicators of socio-ecological inequality. They can be used to develop strategies to reduce country-level health disparity. The objective of this study was to confirm the relationship between socio-ecological factors and OLE in Europe. Data were obtained from World Bank, WHO, and UN database for 34 Europe countries. Associations between socio-ecological factors and OLE were assessed with Pearson correlation coefficients and three regression models. These models assumed that appropriate changes in country-level strategies of healthy aging would produce changes in GNI per capital as personal perspective, GII in social environment perspective, and DCI in public policy perspective to implement socio-ecological changes. Hierarchal linear regression was used for final analysis. Although OLE (women and men) had significant negative correlation with GII (gender inequality index, r = - 0.798, p = 0.001), it had positive correlations with GNI (gross national income per capita, r = 0.834, p = 0.001) and DCI (depth of credit information index, r = 0.704, p = 0.001) levels caused by financial crisis. Higher levels GNI and DCI but lower GII were found to be predictors of OLE (women and men) (R(2) = 0.804, p Europe were identified from socio-ecological perspective. Socio-ecological indicators (GII, GNI, and DCI) in Europe appear to have a latent effect on OLE levels. Thus, country-level strategies of successful aging in Europe should target socio-ecological factors such as GII, GNI, and DCI value.

  3. Risk factors for age-related maculopathy.

    Connell, Paul P

    2012-02-01

    Age-related maculopathy (ARM) is the leading cause of blindness in the elderly. Although beneficial therapeutic strategies have recently begun to emerge, much remains unclear regarding the etiopathogenesis of this disorder. Epidemiologic studies have enhanced our understanding of ARM, but the data, often conflicting, has led to difficulties with drawing firm conclusions with respect to risk for this condition. As a consequence, we saw a need to assimilate the published findings with respect to risk factors for ARM, through a review of the literature appraising results from published cross-sectional studies, prospective cohort studies, case series, and case control studies investigating risk for this condition. Our review shows that, to date, and across a spectrum of epidemiologic study designs, only age, cigarette smoking, and family history of ARM have been consistently demonstrated to represent risk for this condition. In addition, genetic studies have recently implicated many genes in the pathogenesis of age-related maculopathy, including Complement Factor H, PLEKHA 1, and LOC387715\\/HTRA1, demonstrating that environmental and genetic factors are important for the development of ARM suggesting that gene-environment interaction plays an important role in the pathogenesis of this condition.

  4. Age and gender as risk factors for the transmission of HIV in a sample of drug users of Porto Alegre, Brazil Idade e gênero como fatores de risco para a transmissão do HIV em uma amostra de usuários de drogas, Porto Alegre, Brasil

    Full Text Available Objective: To verify the association between age and gender regarding HIV seropositivity in drug users who seek public health centers in Porto Alegre, Brazil. Methods: The authors designed a cross-sectional study with a convenience sampling of 695 men and women aged above 15, who reported recent drug use and risk behaviors to HIV exposure. We used a standard questionnaire (CRA, Brazilian version of the RAB, Risk Assessment Battery to assess risk behaviors and we collected blood for HIV testing. Results: Most individuals were males (75,8%, with a mean age of 29.4 years, less than seven years of schooling (42,4%, and family income equal or superior to four minimum wages (46%. There was no significant association between gender and seropositivity. Multivariate analyses showed that individuals aged above 30 had a three-fold increased odds of being seropositive over subjects aged 20 or less. Intravenous drug users who had been using drugs since 1980 had five-fold odds of seropositivity and those who had been using them in the month prior to the interview had four-fold odds. Discussion: Subjects aged more than 30 showed higher odds of seropositivity than the younger group. This is possibly due to a higher use of intravenous cocaine and to having more risk behaviors along their lifetime. There was no difference in seropositivity between genders, what differs from current data of other studies, if we take into consideration that rates of populational seropositivity among women have increased, mostly among drug users, who are, therefore, at 'double risk'. The development of further studies is mandatory in order to assess gender and age as risk factors for seropositivity, whether to confirm or to deny these findings, and to plan specific strategies for high-risk groups.Objetivo: Verificar se idade e gênero estão relacionados à soropositividade para HIV em usuários de drogas que procuram centros de atendimento em saúde de Porto Alegre.

    2016-12-01

    Full Text Available Ageing/aged bodies reflects gender norms and power relations. The paper is based on analysis of four focus groups realized in homes for older and infirm persons with participants older than 65 years. Old age and ageing are not gender neutral phenomenon – perception, experience, interpretation and strategies of managing of ageing/aged body are gendered. For participants tidiness and cleanliness are most important despite gender. Dominant interpretations of focus groups’ participants reflect traditional understanding of gender roles, gender ideals and internalization of gender and age stereotypes: physical appearance is more important to women than to men; beauty and physical attractiveness are reserved for youth; female sexuality is interpreted as burden, obligation and source of pain for women; menopausa is interpreted as beginning of declining; male ageing bodies were interpreted in functional terms. Negative attitudes toward all types of surgical interventions on face and body are dominant and in this aspect participants reject socio-cultural pres- sures for youthful and glamorous looking in old age.

    Full Text Available The study examined age and gender differences in aggression using three representative samples for Slovenia: 4th grade elementary school students; 8th grade elementary school students; 4th grade secondary school students in Matura programs. The results were based on the LA aggression scale that measures general aggression and four specific types of aggression: physical aggression (TA, verbal aggression (BA, internal aggression (NA and aggression towards authority (AA. Based on the results of two-way ANOVA we found important effects of age, gender and their interaction. The gender differences were significant in the groups of elementary school students but not in secondary school students. Male elementary school students, 4th and 8th grade, were more aggressive compared to female elementary school students. 8th grade elementary school students were more physically, verbally, internally aggressive and more aggressive towards authority when compared to 4th grade elementary school students. Secondary school students were significantly less physically and verbally aggressive, and on the other hand more internally aggressive when compared to both groups of elementary school students. Secondary school students reported higher level of aggression towards authority than 4th grade elementary students, and lower level then 8th grade elementary students. The results were congruent with the findings of the research literature indicating higher aggression of males when compared to females and different developmental paths for different types of aggression in question. The study introduced important findings regarding age and gender differences in representative school samples in Slovenia and proposed future research mostly in direction of including measures of indirect aggression that is linked to female gender and older students.

    Ethnicity, gender and age of onset are reported to influence the expression and outcome of systemic lupus erythematosus. We studied a multi-ethnic cohort of 408 South Africans (91.2% females) comprising 237 (58.1%) Indians, 137 (33.6%) African Blacks, 17 (4.2%) Mixed ethnicity and 17 (4.2%) Whites. The most common manifestations were arthritis (80.6%), photosensitivity (67.2%), oral ulcers (50.0%), malar rash (49.0%) and renal (39.2%). The common laboratory findings were positive anti-nuclear factor (96.8%), haematological (74.8%) and anti-dsDNA antibodies (45.3%). Serositis ( p = 0.002), nephritis ( p = 0.039), leucopaenia ( p = 0.001), haemolytic anaemia ( p = 0.026), anti-dsDNA antibodies ( p = 0.028) and anti-Sm antibodies ( p = 0.050) were more common in African Blacks compared to Indians. Males had increased prevalence of discoid rash ( p = 0.006) and anti-Sm antibodies ( p = 0.016). Discoid rash ( p = 0.018), renal involvement ( p systemic lupus erythematosus. On multivariate analysis, the independent predictors of death were renal involvement, anti-dsDNA antibodies and seizures. There were 53 (13%) deaths and the five- and 10-year survival was 90.8% and 85.7% respectively, with no differences related to ethnicity or age of onset. In conclusion, we report on the spectrum and outcome of systemic lupus erythematosus in a large South African multi-ethnic cohort.

    Full Text Available OBJECTIVE: to analyze the influence of gender and age on the quality of the professional lives of health care professionals at a university hospital. METHOD: a total of 546 professionals completed a general questionnaire that measured sociodemographic variables and evaluated job satisfaction using a scale adopted from the NTP 394 Job Satisfaction scale and translated into Spanish. RESULTS: overall, 77.2% of the professionals surveyed were satisfied with the work they perform. With regards to gender, we found overwhelming evidence of the feminization of practically all health care professions included in the study, with higher levels of job satisfaction among women than men. Regarding age, 20-30-year-olds and professionals over 61 years old showed higher satisfaction levels than did middle-aged professionals. Higher levels of dissatisfaction were reported by professionals between 41 and 50 years old. CONCLUSIONS: we were able to detect the influence of gender and age on the level of job satisfaction, finding significant associations between job satisfaction and both of these variables. Generally, women expressed more satisfaction than men, and elderly professionals showed higher satisfaction compared to younger professionals. Management policies should focus on taking action to correct the conditions that produce dissatisfaction among certain groups of employees.

    The relationship between thyroid dysfunction and metabolic syndrome (MS) is complex. We aimed to explore the impact of gender and age on their association in a large Chinese cohort. This cross-sectional study enrolled 13,855 participants (8532 male, 5323 female), who self-reported as healthy without any known previous diseases. Clinical data including anthropometric measurements, thyroid function, and serum metabolic parameters were collected. The associations between thyroid function and MS of both genders were analyzed separately after dividing thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), and age into subgroups. MS risks were calculated by binary logistic regression models. Young males had significantly higher MS prevalence than females, yet after menopause, females had higher prevalence than males. Females had higher incidence of thyroid dysfunction than males. By using TSH quartiles as the categorical variables and the lowest quartile as reference, significantly increased MS risk was demonstrated in quartile 4 for males, yet quartiles 3 and 4 for females. By using FT3 quartiles as the categorical variables, significantly increased MS risk was demonstrated in quartile 2 to 4 for females only. By using age subgroups as the categorical variables, significantly increased MS risk was shown in both genders, with females (4.408-58.455) higher than males (2.588-4.943). Gender and age had substantial influence on thyroid function and MS. Females with high TSH and high FT3 had higher MS risks than males. Aging was a risk for MS, especially for females. Urgent need is necessary to initiate interventional programs.

    2012-12-01

    The present paper investigates possible gender and age differences on emotional states (depression and anxiety) and self-esteem as well as the association between self-esteem and emotional states. The cross-sectional sectional sample consists of 1,209 adolescents 13-18 years from public elementary and secondary schools in mid-Norway. The results showed that girls reported higher scores on state anxiety and state depression, whereas boys consistently scored higher on self-esteem in all age groups. Self-esteem was strongly and inversely associated with both state depression and state anxiety. An interaction effect of gender by self-esteem was found on state depression, where the association was stronger for girls than for boys. The associations found give support for the positive role of self-esteem in relation to adolescents' emotional health and well-being.

    Humanitarian aid remains largely driven by anecdote rather than by evidence. The contemporary humanitarian system has significant weaknesses with regard to data collection, analysis, and action at all stages of response to crises involving armed conflict or natural disaster. This paper argues that humanitarian actors can best determine and respond to vulnerabilities and needs if they use sex- and age-disaggregated data (SADD) and gender and generational analyses to help shape their assessments of crises-affected populations. Through case studies, the paper shows how gaps in information on sex and age limit the effectiveness of humanitarian response in all phases of a crisis. The case studies serve to show how proper collection, use, and analysis of SADD enable operational agencies to deliver assistance more effectively and efficiently. The evidence suggests that the employment of SADD and gender and generational analyses assists in saving lives and livelihoods in a crisis.

    The present study examined associations between emotional awareness facets (type clarity, source clarity, negative emotion differentiation, voluntary attention, involuntary attention) and sociodemographic characteristics (age, gender, and socioeconomic status (SES)) in a large US sample (N = 919). Path analyses-controlling for variance shared between sociodemographic variables and allowing emotional awareness facets to correlate-demonstrated that (a) age was positively associated with type clarity and source clarity, and inversely associated with involuntary attention; (b) gender was associated with all facets but type clarity, with higher source clarity, negative emotion differentiation, voluntary attention, and involuntary attention reported by women then men; and (c) SES was positively associated with type clarity with a very small effect. These findings extend our understanding of emotional awareness and identify future directions for research to elucidate the causes and consequences of individual differences in emotional awareness.

    Full Text Available The study investigated the influence of geographical location, gender and age on the performance of Piagetian Conservation tasks. Four conservation tasks; conservation of liquid, length, substance amount and number respectively were administered to children [4-6 years] from rural and urban Ghana and their performance on each task were recorded. Results indicated that there were no significant relationships among the performance of Piagetian conservation tasks and geographical location. Similar trends were noted in the performance of gender and age differences on Piagetian conservation tasks. Nonetheless, older children performed better on the conservation of liquid in a glass than younger children. Based on the results, both quantities and perceptual comparisons can be applied in future studies to examine some possible variations in children’s cognitive development.

    Controversy exists concerning the etiological factors behind degenerative changes in the temporomandibularjoints (TMJs). Occlusal factors, ageing, gender and genetics are some factors that have been discussed. The aim of the present study was to examine a contemporary human skull material in respect of gender, age, occlusal variables and form and surface changes in the temporomandibular joints. The material consisted of 259 human skulls, 170 males and 89 females, with an age range of 18-100 years. The over all dental status was poor, and 22% were edentulous. Both medio-lateral and antero-posterior dimensions as well as anterior and superior shape of the condyles were in good agreement with previous results. Form and surface changes of both the condyles and the temporal components were, however, more common in the present material compared to most previous studies. Men had on average more degenerative changes in the TMJs compared to women. In agreement with many previous studies, there was an increase of such changes with increasing age. Severe tooth attrition was a common finding, especially in men, but no correlation was found between this variable and the severity of degenerative changes in the TMJs. Abfractions were found in only 3 cases. Considering the common finding of severe tooth attrition,the rare occurrence of abfractions does not lend support to the hypothesis that abfractions are mainly caused by occlusal loading. Condylar dimensions and shape of the condyles were in good agreement with previously presented results. Severe tooth attrition and pronounced degenerative changes in the TMJs were common findings but no statistically significant association was found between these two variables.

    The objective was to examine gender differences and similarities in health, function, familial and non-familial social networks; longitudinal resilience in those factors; and their association with risk of mortality in Israeli men and women aged 75-94. We used the Cross-Sectional and Longitudinal Aging Study (CALAS), a stratified random sample of 960 Israeli Jews aged 75-94, drawn on January 1, 1989 from National Population Registry, stratified by gender, age (75-79, 80-84, 85-89, 90-94), and place of birth (Europe/America, Middle East/North Africa, Israel), interviewed twice (Wave 1, 1989-1992; Wave 2, 1993-1995); Wave 1 values and longitudinal resilience predicted the 1999 mortality risk for those alive at both waves. Gender differences and similarities were found at Wave 1 in longitudinal resilience and in risk factors for mortality, partially supporting a gender paradox. Men were more physically active, had better cognition, gave more help to children, relied less on paid caretakers, and attended synagogue more than women, factors associated with better health and functioning. Women had poorer health and functional status and more help from children. More physical activity, synagogue attendance, and resilience in activities of daily living (ADL) were associated with lower risk of mortality for both genders. Women's risk of mortality was reduced by smoking reduction and higher cognitive vitality, and men's by emotional support and solitary leisure activity. Both men and women were resilient, yet there were differences. Gender-neutral mortality reduction programs would include physical activity, religious services, maintenance and improvement of ADL, and engaging in solitary leisure activities; for women, smoking cessation and cognitively challenging activities; and for men, maintaining or increasing emotional ties.

    Full Text Available Background: Thyroid is an endocrine gland located below the larynx. The principal thyroid hormones are thyroxine (T4, tri-iodothyroxine (T3. The current study was carried out to investigate the impact of age, gender and seasons on the level of Thyroxine (T4, Triiodothyronine (T3 and Thyroid Stimulating Hormone in individuals free of thyroid diseases. Methods: - Serum levels of T3, T4 and TSH in 198 individuals attending Dhiraj General Hospital in different seasons were examined. Hormonal assay was done by using AIA 360 immunoassay. Results: - Levels of T3, T4 and TSH ranged from 0.98-4.8ng/dl, 0.56-3-25ng/dl and 0.01-5.3μIU/L. There is significant change in thyroid hormone levels in both genders of different age group in different seasons. Conclusion:- It is concluded that the age, gender and seasons have an appreciable effects on the levels T3, T4 and TSH. [National J of Med Res 2011; 1(2.000: 57-59

    The aim of the present study was to evaluate the effects of age and gender on selected vocal fold vibratory behaviors during vowel prolongation and connected speech using electroglottography (EGG). Forty-six young and older individuals (23 males and 23 females) with normal voices participated in this study. EGG parameters including fundamental frequency and contact quotient were measured during sustained vowel prolongation and connected speech tasks. Significant age-by-gender interactions were found for both parameters. Moreover, results from discriminant function analyses revealed that the overall accuracies of the parameters in predicting different age and gender groups were higher for the connected speech tasks than for the sustained vowel prolongation task (89.1% and 73.9% for passage and phrase tasks vs 71.7% for vowel prolongation). These findings suggest that reliability of EGG measures can be affected by the test stimuli. Therefore, one should carefully consider the use of the speech material when assessing vocal fold behaviors using EGG. The findings also support the use of connected speech stimulus, preferably at passage level, in electroglottographic evaluation for a better representation of vocal fold vibrating behaviors.

    Full Text Available The main purpose of this article is to analyze the main ideas of the Medieval Period authors in Europe and in Russia, in terms of identifying the most important theses of this historical period for the formation and development of the ideas of gender psychology. It is being considered the role of Christianity and the emergence of the women's education issue in the formation of gender stereotypes. In this article the Middle Ages period is being considered as a separate historical phase for the basic ideas formation in the gender psychology, which is a new approach to the history of gender science. To estimate medieval texts - European and Russian, the method of qualitative content analysis is used, by means of which the most relevant to the period ideas associated with the sexes are identified. For Europe, it inter-sexual features, for Russia - different behavioral requirements of the society associated with sexes. Conclusions contain ideas of the Middle Ages in Europe and in Russia that are relevant to the development and establishment of gender psychology. In Europe: the continuation of the ancient thesis of the initial androgyny of a human being; impact of the woman's education on her ability for development; consideration of sexuality as sinful; the issue of women's emancipation, the declining value of the large numerous families despite of a ban on interference in the reproductive cycle in the middle of the Medieval period. In Russia: the perception of inter-sexual characteristics as defined by the God; unconditional obedience of a woman to her husband; androgyny in the distribution of the farmers’ responsibilities.Objective: To analyze the main ideas of the authors of the Middle Ages in Europe and in Russia, in terms of identifying the significant theses of this historical period for the formation and development of the ideas of the gender psychology.Method of the research work: A qualitative content analysis of the texts by the authors

    Full Text Available Abstract Background Public health research characterising the course of life through the middle age in developing societies is scarce. The aim of this study is to explore patterns of adult (15–64 years mortality in an Ethiopian population over time, by gender, urban or rural lifestyle, causes of death and in relation to household economic status and decision-making. Methods The study was conducted in Butajira Demographic Surveillance Site (DSS in south-central Ethiopia among adults 15–64 years old. Cohort analysis of surveillance data was conducted for the years 1987–2004 complemented by a prospective case-referent (case control study over two years. Rate ratios were computed to assess the relationships between mortality and background variables using a Poisson regression model. In the case-referent component, odds ratios (95% confidence intervals were used to assess the effect of certain risk factors that were not included in the surveillance system. Results A total of 367 940 person years were observed in a period of 18 years, in which 2 860 deaths occurred. One hundred sixty two cases and 486 matched for age, sex and place of residence controls were included in the case referent (case control study. Only a modest downward trend in adult mortality was seen over the 18 year period. Rural lifestyle carried a significant survival disadvantage [mortality rate ratio 1.62 (95% CI 1.44 to 1.82, adjusted for gender, period and age group], while the overall effects of gender were negligible. Communicable disease mortality was appreciably higher in rural areas [rate ratio 2.05 (95% CI 1.73 to 2.44, adjusted for gender, age group and period]. Higher mortality was associated with a lack of literacy in a household, poor economic status and lack of women's decision making. Conclusion A complex pattern of adult mortality prevails, still influenced by war, famine and communicable diseases. Individual factors such as a lack of education, low economic

    This work is part of a qualitative socio-cultural investigation with a group of men and women 40 years and older in the maquila export industry in Nogales, Sonora, Mexico. In 1994, as a result of the North American Free Trade Agreement, maquila plants combined traditional intensive work methods with new "just in time" production norms that impacted work and health conditions, particularly in older, or aging, workers. The workers that were interviewed for this study show a reduction in their functional ability to work starting at 40 years of age. Work organization demands, general health conditions, and a decrease in physical abilities brings these 40-year-old workers to prematurely construct an image of themselves as aging workers and to develop coping strategies that vary by gender.

    This study had three purposes: (a) to compare the prevalence of boys' and girls' gender-atypical behaviors (GABs) in a sample of Chinese school-aged children, (b) to examine the developmental pattern of GABs in Chinese boys and girls over the age range in question (6-12 years), and (c) to test the effects of being an only child on children's GAB expression. Parents of 486 boys and 417 girls completed a Child Play Behavior and Activity Questionnaire (CPBAQ) in regard to their own children, and a demographic information sheet. The frequency distribution for each gender-related behavior was calculated. The associations between sex, age, and only-child status, and CPBAQ scale scores were examined. Although most GABs (by their very nature) were exhibited infrequently in Chinese children, it was found that girls displayed GABs more frequently than boys did. The prevalence of GABs rose for girls as they grew older, but fell slightly for boys. The expressions of GABs in only children did not differ from that in children with siblings. Possible effects of Chinese culture (including the current only-child policy) on children's GABs are discussed.

    Full Text Available Background: The geographical difference in presentation of primary hyperparathyroidism (PHPT is known. However, there is sparse literature on the influence of age and gender on presentation of PHPT. Aim: To analyze the effect of age and gender on presentation of symptomatic primary hyperparathyroidism. Setting and Design: This is a retrospective analysis of data from the primary hyperparathyroidism registry of a north Indian tertiary care teaching institute. Materials and Methods: Analysis of 184 histopathologically proven PHPT patients registered between March 1990 and March 2010 from a single centre of north India. PHPT patients were divided into three different age groups i.e. children and adolescents less than 25 years, adults 25-49 years, and ≥ 50 years. Clinical presentations, biochemical parameters and parathyroid weight were compared between different age groups and gender using appropriate statistical methods. Results: Mean age of patients was 38.5±13.8 years with female: male ratio of 7:3. Rickets as presenting manifestations were seen in one child and adolescent each. Prevalence of renal stones (P=0.03 and gall stones (P=0.02 was higher in the adult groups compared to the younger and older. There was no difference in bone pain (P=0.7, fracture (P=0.3, osteitis fibrosa cystica (P=0.2, fatigue (P=0.6 and other symptoms among different age groups. There was no difference in serum calcium, phosphate, parathyroid hormone (PTH and 25 (OH D levels among different age groups, however, as expected alkaline phosphatase was higher in adolescents compared to adults (P=0.03. Bone pain and muscle aches (P<0.001, fracture (P=0.04, osteitis fibrosa cystica (P=0.01, and gall stones (P=0.03 were more common among women while renal stones (P=0.05 and pancreatitis (P=0.02 were common in men.

    The aim of this study was to determine whether the socioeconomic status (SES) of parents influences early childhood unintentional injury deaths for different injury mechanisms and the gender and age at death of the child. Study design is a population-based retrospective study. Death certificate data from 1995 to 2004 were linked to birth certificate data from 1995 to 1996 for each child who died when aged Parental age, birth order, marital status, residence area, educational level, and occupation were used as indices for SES. Cox proportional-hazards analysis was employed. Our results indicate that nonmetropolitan residence, low parental education level, and a father working in a nonadministrative job or as a farmer were associated with a higher risk of death from injury for both boys and girls. A mother aged younger than 20 years and parents working in manual jobs were associated with a higher risk in boys only. The risks of some socioeconomic factors (low parental education and a father working in a manual job or as a farmer) were evident for children aged 1-4 years. The risks of rural residency tended to increase in older children, and the risk of injury from having a mother aged younger than 20 years increased for younger children. The risks of childhood injury deaths from traffic accidents, falls, and fire/burns were associated with the SES of the parents. Younger parents were associated with higher risks of injury deaths from traffic accidents (hazard ratio [HR]: father, 7.9; mother, 1.9) and falls (HR: father, 2.0; mother, 2.5). A father working as a farmer was associated with a higher risk of childhood injury death from fire/burns (HR = 4.0). In conclusion, the parental SES risk profiles of childhood injury deaths varied with the age and gender of the child, and with the injury mechanism. Therefore, reducing excess injury deaths during early childhood requires preventive efforts targeted at high-risk parents, and based on injury mechanism and on the gender

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

    Ability patterns and surgical proficiency were examined in matched groups of general surgery residents selected on the basis of age, gender, or hand preference from a population of 141 residents who had completed neuropsychologic tests of visuospatial, psychomotor, and stress tolerance abilities and had been rated on 12 aspects of technical skill exhibited during 1480 operative procedures. Older residents (ages 28 to 42 years) exhibited less motor speed (p less than 0.05) and coordination (p less than 0.005) and more caution in avoiding psychomotor errors (p less than 0.05) than did their younger counterparts. No differences were found for visuospatial abilities, stress tolerance, or rated surgical skill. These findings indicate that although age does appear to adversely affect pure motor skills, these are not important components of operative proficiency. Female residents exhibited superior (p less than 0.05) academic achievement (MCAT, Verbal and National Boards Part II) as compared with their male counterparts. They also excelled on a signal detection task requiring identification of visual patterns. However, the women scored less well (p less than 0.05) than men on a visuomotor task demonstrated to be a significant predictor of operative skill. Greater cautiousness in avoiding errors may be a contributing factor to their reduced efficiency on this task. In comparison to male controls, female residents received consistently lower surgical skills ratings, particularly on items measuring confidence and task organization. Left-handed residents were more reactive to stress (p less than 0.03), more cautious (p less than 0.04), and more proficient on a neuropsychologic test of tactile-spatial abilities (p less than 0.03) than right-handed counterparts. Although these traits correlated positively (p less than 0.05) with rated operative skill within the left-handed group, the group received consistently lower ratings than did right-handed residents.

    Prolonged conflict in South Sudan exacerbated gender disparities and inequities. This study assessed differences in attitudes towards gender inequitable norms and practices by sex, age and education to inform programming. Applying community-based participatory research methodology, 680 adult respondents, selected by quota sampling, were interviewed in seven South Sudanese communities from 2009 to 2011. The verbally administered survey assessed attitudes using the Gender Equitable Men scale. Data were stratified by sex, age and education. Of 680 respondents, 352 were female, 326 were male and two did not report their sex. The majority of respondents agreed with gender inequitable household roles, but the majority disagreed with gender inequitable practices (i.e., early marriage, forced marriage and inequitable education of girls). Respondents who reported no education were more likely than those who reported any education to agree with gender inequitable practices (all p forced marriage (p = 0.07), and few significant differences were observed when these responses were stratified by sex and by age. The study reveals agreement with gender inequitable norms in the household but an overall disagreement with gender inequitable practices in sampled communities. The findings support that education of both women and men may promote gender equitable norms and practices.

    Social functioning (SF) is the ultimate target aimed in treatment plans in schizophrenia, thus it is critical to know what are the factors that determine SF. Gender is a well-established variable influencing SF, yet it is not known how social variables and symptoms interact in schizophrenia patients. Furthermore, it remains unclear whether the interaction between social variables and symptoms is different in men compared to women. Our aim is to test whether social variables are better predictors of SF in community-dwelled individuals with schizophrenia, and whether men and women differ in how symptoms and social variables interact to impact SF. Community-dwelling individuals with schizophrenia (N = 231) were randomly selected from a register. Participants were assessed with symptom measures (PANSS), performance-based social scale (LSP), objective social and demographic variables. Stratification by gender and stepwise multivariate regression analyses by gender were used to find the best-fitting models that predict SF in both gender. Men had poorer SF than women in spite of showing similar symptom scores. On stepwise regression analyses, gender was the main variable explaining SF, with a significant contribution by disorganized and excitatory symptoms. Age of onset made a less marked, yet significant, contribution to explain SF. When the sample was stratified by gender, disorganized symptoms and 'Income' variable entered the model and accounted for a 30.8% of the SF variance in women. On the other hand, positive and disorganized symptoms entered the model and accounted for a 36.1% of the SF variance in men. Community-dwelling men and women with schizophrenia differ in the constellation of variables associated with SF. Symptom scores still account for most of the variance in SF in both genders.

Our research found that in this period, aggregate spending on children's health care increased at the slowest rate. However, per capita spending for children grew more rapidly than that for working-age adults and the elderly. Per capita spending for the elderly remained about five times higher than spending for children. Overall, females spent more per capita than males, but the gap had decreased by 2010. The implementation of Medicare Part D, the effects of the recent recession, and the aging of the baby boomers affected the spending trends and distributions during the period of this study.

    Full Text Available The aim of the study was to determine the values of selected haematological indices of the Polbar breed of chickens by gender and age. There was a significant WBC difference in cocks and hens with age. In each of the periods, cocks were characterized by a lower than hens number of LY. LY and NE declined with increasing age. Most values showed significant (P ≤ 0.05 differences for birds at different ages. These results of the haematological indices from consolidated Polbar breed can be used for comparisons with other breeds of poultry. The study deepens and organizes the knowledge within the possibilities of using and interpreting levels of haematological indicators for monitoring health of hens. In this paper, we managed to obtain information on the level of indicators rarely determined in chickens.

    Full Text Available Background: The factor structure of posttraumatic stress disorder (PTSD has been extensively studied in Western countries. Some studies have assessed its factor structure in Asia (China, Sri Lanka, and Malaysia, but few have directly assessed the factor structure of PTSD in an Indian adult sample. Furthermore, in a largely patriarchal society in India with strong gender roles, it becomes imperative to assess the association between the factors of PTSD and gender. Objective: The purpose of the present study was to assess the factor structure of PTSD in an Indian sample of trauma survivors based on prevailing models of PTSD defined in the DSM-IV-TR (APA, 2000, and to assess the relation between PTSD factors and gender. Method: The sample comprised of 313 participants (55.9% female from Jammu and Kashmir, India, who had experienced a natural disaster (N=200 or displacement due to cross-border firing (N=113. Results: Three existing PTSD models—two four-factor models (Emotional Numbing and Dysphoria, and a five-factor model (Dysphoric Arousal—were tested using Confirmatory Factor Analysis with addition of gender as a covariate. The three competing models had similar fit indices although the Dysphoric Arousal model fit significantly better than Emotional Numbing and Dysphoria models. Gender differences were found across the factors of Re-experiencing and Anxious arousal. Conclusions: Findings indicate that the Dysphoric Arousal model of PTSD was the best model; albeit the fit indices of all models were fairly similar. Compared to males, females scored higher on factors of Re-experiencing and Anxious arousal. Gender differences found across two factors of PTSD are discussed in light of the social milieu in India.

Most patients with chronic obstructive pulmonary disease (COPD are elderly and have poor lung function. The factors affecting their inspiratory flows through inhalers are unclear.Objective: To study peak inspiratory flows (PIFs and their determinants through a DPI in COPD patients of varying age and severity.Methods: Flow-volume spirometry was performed in 93 COPD patients. Maximum PIF rates were recorded through an empty Easyhaler® (PIFEH; Orion Corporation, Espoo, Finland, a DPI that provides consistent dose delivery at inhalation rates through the inhaler of 28 L/min or higher.Results: The mean PIFEH was 54 L/min (range 26–95 L/min with a coefficient of variation of 7%. All but two patients were able to generate a flow of ≥28 L/min. In a general linear model, the independent determinants for PIFEH were age (P = 0.02 and gender (P = 0.01, and forced expiratory volume in 1 s (FEV1 expressed as percent predicted was not a significant factor. The regression model accounted only for 18% of the variation in PIFEH.Conclusion: In patients with COPD, age and gender are more important determinants of inspiratory flow through DPIs than the degree of expiratory airway obstruction. Most COPD patients with varying age and severity are able to generate inspiratory flows through the test inhaler that is sufficient for optimal drug delivery to the lower airways.Keywords: COPD, forced expiratory volume, peak inspiratory flow

    Drosophila melanogaster is increasingly used for study aging mechanism and evaluating anti-aging drugs, but the changes of metabolites and differences of metabolites change between male and female during the aging process are not well known. Metabolomics technology, a massive information provider, has promoted the understanding of metabolic profile and overall changes of metabolites in organism. In this study, (1)H NMR based metabonomics was employed to investigate the dynamic changes of metabolites in whole bodies of male and female Drosophila melanogaster at 3, 15, 30, 45days and to research the gender gap of metabolites changes in aging process. The results showed that the metabolic profile at different ages in both male and female Drosophila melanogaster were separated obviously by multivariate analysis. Besides, the variety track of metabolites between male and female Drosophila melanogaster were different, the change speed in female was significantly slow than that in male. In addition, the results showed 14 metabolites (including leucine, valine, alanine, methionine, cysteine, phenylalanine, glycine, glutamine, tyrosine, tryptophan and histidine, succinate, xanthine and DMA) were associated with aging and 7 metabolites (including leucine, valine, methionine, cysteine phenylalanine, succinate and DMA) were associated with gender gap in the aging process of Drosophila melanogaster. Corresponding metabolic mechanisms referenced to the KEGG database and literatures were discussed. This study demonstrate that metabolomics is promising as a valuable method not only to reveal metabolites that related to senescence, but also to help us understand differences between male and female flies in aging process.

    Engaging employees can have a positive effect on turnover reduction, client satisfaction, company profitability, innovation and growth. Engaging employees in corporate social responsibility (CSR) can also generate positive impacts on environment and society. To do this, companies need to understand...... their employees' CSR attitudes. In this regard, many studies show that individual characteristics can influence CSR attitudes. This research aims to identify the influence of three sociodemographic characteristics such as gender, educational level and age on three employee CSR attitudes, such as CSR demandingness...... and satisfied than female colleagues. Educational level differences also have a significant influence on CSR trust and CSR satisfaction, with graduated employees generally more trustful and satisfied than not graduated colleagues. However, employee gender and education do not influence CSR demandingness...

  6. Gender roles and social policy in an ageing society: the case of Japan

    Meiko Makita

    2010-10-01

    Full Text Available This article reviews the major underpinnings of the Japanese welfare state in the context of social care from a feminist perspective. In Japan, familycare responsibilities have traditionally been assigned to women; hence, care has long been a women’s issue. However, as the social contract of a male breadwinner and a “professional housewife” gradually fades out, Japanese women find more opportunities to renegotiate their caring roles. Of course, this social transformation did not occur in isolation, it was influenced by patterns in economic development, state policies and mainly demographic changes. All this has stimulated new state responses in the form of social welfare expansion that arguably aim to relieve women of the burdens of family-care. The issue remains, however, as to whether Japan would be able to recognise that the main structural issues of population ageing do not originate from demographic changes, but from a strict gendered division of labour and gender inequality.

    Gender is a one of the most important social determinants of health inequality. Ukrainian life expectancy gender gap is almost ten years in favor of women. Data from the 2 - 6 rounds (N=5158) of a European Social Survey are used to show gender differences in self-reported health (IBM SPSS 22......). It was assumed that women reported poorer health status compared with men despite of longevity. Women estimate their health significantly lower than men do (OR 1.83; 95% CI 1.65, 2.04). For both genders, age and feeling about household’s income nowadays were associated with increased odds for poor self...

    We report a prospective study of the incidence of fractures in the adult population of Edinburgh, related to age and gender. Over a two-year period, 15,293 adults, 7428 males and 7865 females, sustained a fracture, and 5208 (34.0%) required admission. Between 15 and 49 years of age, males were 2.9 times more likely to sustain a fracture than females (95% CI 2.7 to 3.1). Over the age of 60 years, females were 2.3 times more likely to sustain a fracture than males (95% CI 2.1 to 2.4). There were three main peaks of fracture distribution: the first was in young adult males, the second was in elderly patients of both genders, mainly in metaphyseal bone such as the proximal femur, although diaphyseal fractures also showed an increase in incidence. The third increase in the incidence of fractures, especially of the wrist, was seen to start at 40 years of age in women. Our study has also shown that 'osteoporotic' fractures became evident in women earlier than expected, and that they were not entirely a postmenopausal phenomenon.

    Few studies have been conducted in people of Asian descent that have reported to demonstrate the distinct developmental trends in good self-control and poor control. To fill this gap, we conducted a national cross-sectional survey among adolescents and young adults in China to further clarify the age and gender differences in self-control from a dual-systems perspective. A total of 2910 adolescents (female, n = 1698) and their parents from five different provinces in China were surveyed using the Dual-Modes of Self-Control Scale (DMSC-S) and the Parents' Perceived Self-Control Scale. The mean age of the adolescent sample was 17.47 years (ranging from 12.50 to 25.42 years). Boys exhibited greater good self-control than girls. Poor control increased between 12 and 17 years of age and declined thereafter; however, good self-control increased over the entire study period. Both good self-control and poor control in student participants were significantly associated with parents' perceived self-control; moreover, the association between good self-control and parental self-control was mediated by SES. The roles of age, gender, parental self-control and SES varied in a dual-systems model of self-control: good self-control and poor control. Implications of these results are discussed. © 2016 John Wiley & Sons Ltd.

    Full Text Available Tracheal disorders can usually reduce the free lumen diameter or wall stiffness, and hence limit airflow. Trachea tissue engineering seems a promising treatment for such disorders. The required mechanical compatibility of the prepared scaffold with native trachea necessitates investigation of the mechanical behavior of the human trachea. This study aimed at mechanical characterization of human tracheas and comparing the results based on age and gender. After isolating 30 human tracheas, samples of tracheal cartilage, smooth muscle, and connective tissue were subjected to uniaxial tension to obtain force-displacement curves and calculate stress-stretch data. Among several models, the Yeoh and Mooney-Rivlin hyperelastic functions were best able to describe hyperelastic behavior of all three tracheal components. The mean value of the elastic modulus of human tracheal cartilage was calculated to be 16.92 ± 8.76 MPa. An overall tracheal stiffening with age was observed, with the most considerable difference in the case of cartilage. Consistently, we noticed some histological alterations in cartilage and connective tissue with aging, which may play a role in age-related tracheal stiffening. No considerable effect of gender on the mechanical behavior of tracheal components was observed. The results of this study can be applied in the design and fabrication of trachea tissue engineering scaffolds.

    Background: There is increasing evidence that in utero growth has both immediate and far-reaching influence on health. Birth weight and length are used as surrogate measures of in utero growth. However, these measures poorly reflect neonatal adiposity. Air-displacement plethysmography has been validated for the measurement of body fat in the neonatal population. Objective: The goal of this study was to show the normal reference values of percentage body fat (%BF) in infants during the first 4 days of life. Methods: As part of a large population-based birth cohort study, fat mass, fat-free mass, and %BF were measured within the first 4 days of life using air-displacement plethsymography. Infants were grouped into gestational age and gender categories. Results: Of the 786 enrolled infants, fat mass, fat-free mass, and %BF were measured in 743 (94.5%) infants within the first 4 days of life. %BF increased significantly with gestational age. Mean (SD) %BF at 36 to 37 weeks\\' gestation was 8.9% (3.5%); at 38 to 39 weeks\\' gestation, 10.3% (4%); and at 40 to 41 weeks\\' gestation, 11.2% (4.3%) (P < .001). Female infants had significantly increased mean (SD) %BF at 38 to 39(11.1% [3.9%] vs 9.8% [3.9%]; P = .012) and at 40 to 41 (12.5% [4.4%] vs 10% [3.9%]; P < .001) weeks\\' gestation compared with male infants. Gender- and gestational age-specific centiles were calculated, and a normative table was generated for reference. Conclusion: %BF at birth is influenced by gestational age and gender. We generated accurate %BF centiles from a large population-based cohort.

    Full Text Available To examine the relationships between physical function and gender-stereotyped traits and whether these relationships are modified by sex or social context.A total of 1995 community-dwelling older adults from the International Mobility in Aging Study (IMIAS aged 65 to 74 years were recruited in Natal (Brazil, Manizales (Colombia, Tirana (Albania, Kingston (Ontario, Canada, and Saint-Hyacinthe (Quebec, Canada. We performed a cross-sectional analysis. Study outcomes were mobility disability, defined as having difficulty in walking 400 meters without assistance or climbing a flight of stairs without resting, and low physical performance, defined as a score < 8 on the Short Physical Performance Battery. The 12-item Bem Sex Role Inventory (BSRI was used to classify participants into four gender roles (Masculine, Feminine, Androgynous, and Undifferentiated using site-specific medians of femininity and masculinity as cut-off points. Poisson regression models were used to estimate prevalence rate ratios (PRR of mobility disability and poor physical performance according to gender roles.In models adjusted for sex, marital status, education, income, and research site, when comparing to the androgynous role, we found higher prevalence of mobility disability and poor physical performance among participants endorsing the feminine role (PRR = 1.20, 95% confidence interval (CI 1.03-1.39 and PRR = 1.37, CI 1.01-1.88, respectively or the undifferentiated role (PRR = 1.23, 95% CI 1.07-1.42 and PRR = 1.58, CI 1.18-2.12, respectively. Participants classified as masculine did not differ from androgynous participants in prevalence rates of mobility disability or low physical performance. None of the multiplicative interactions by sex and research site were significant.Feminine and undifferentiated gender roles are independent risk factors for mobility disability and low physical performance in older adults. Longitudinal research is needed to assess the mediation

    Fesoterodine, a new antimuscarinic agent for overactive bladder, undergoes immediate and extensive hydrolysis by nonspecific esterases to 5-hydroxymethyl tolterodine (5-HMT), the metabolite principally responsible for its antimuscarinic activity. Formation of 5-HMT does not require cytochrome P450 (CYP)-mediated metabolism, but its further metabolism and inactivation involves CYP3A4 and CYP2D6 isoenzymes. Subject age, gender, and race can play a key role in inter-subject variability in pharmacokinetics and thus efficacy and safety of drugs. This article examines the effects of age, gender, and race on the pharmacokinetics and pharmacodynamics of fesoterodine. Data from two randomized, double-blind, placebo-controlled, parallel-group trials in healthy subjects are presented: Study 1 investigated the effects of race (white vs. black men) and Study 2 investigated the effects of age (young vs. old men) and gender (elderly men vs. elderly women) on the pharmacokinetics and pharmacodynamics of single doses of fesoterodine 8 mg. In both studies, the primary endpoints were area under the concentration-time curve up to the last sample (AUC0-tz) and maximum concentration (Cmax) of 5-HMT in plasma. Pharmacodynamic variables included spontaneous salivary secretion (Studies 1 and 2) and residual urine volume (Study 2 only). The two studies included 5 groups of 16 subjects each (randomized 3 : 1 to fesoterodine or placebo): white men aged 18 - 45 years, black men aged 18 - 45 years (Study 1); young white men aged 18 - 40 years, elderly white men aged > 65 years, and elderly white women aged > 65 years (Study 2). There were no clinically meaningful differences in the primary endpoints between white and black subjects or between young white men, elderly white men, and elderly white women. Mean AUC0-tz was 70.7 ng/ml x h in whites and 64.1 ng/ml x h in blacks; mean Cmax was 6.1 and 5.5 ng/ml in whites and blacks, respectively. Mean AUC0-tz in young white men, elderly white men, and

  16. Do gender differences in audio-visual benefit and visual influence in audio-visual speech perception emerge with age?

    2015-07-01

    Full Text Available Gender and age have been found to affect adults’ audio-visual (AV speech perception. However, research on adult aging focuses on adults over 60 years, who have an increasing likelihood for cognitive and sensory decline, which may confound positive effects of age-related AV-experience and its interaction with gender. Observed age and gender differences in AV speech perception may also depend on measurement sensitivity and AV task difficulty. Consequently both AV benefit and visual influence were used to measure visual contribution for gender-balanced groups of young (20-30 years and middle-aged adults (50-60 years with task difficulty varied using AV syllables from different talkers in alternative auditory backgrounds. Females had better speech-reading performance than males. Whereas no gender differences in AV benefit or visual influence were observed for young adults, visually influenced responses were significantly greater for middle-aged females than middle-aged males. That speech-reading performance did not influence AV benefit may be explained by visual speech extraction and AV integration constituting independent abilities. Contrastingly, the gender difference in visually influenced responses in middle adulthood may reflect an experience-related shift in females’ general AV perceptual strategy. Although young females’ speech-reading proficiency may not readily contribute to greater visual influence, between young and middle-adulthood recurrent confirmation of the contribution of visual cues induced by speech-reading proficiency may gradually shift females AV perceptual strategy towards more visually dominated responses.

    Left ventricular (LV) wall thickening is the most consistent clinical marker of hypertrophic cardiomyopathy (HC), and characteristically increases substantially during adolescence. In this study, we used 2-dimensional echocardiography to develop a cross-sectional profile of LV wall thicknesses in adult patients with HC. We studied a regional community-based cohort of 239 consecutively enrolled patients (aged 18 to 91 years). On average, maximum LV wall thickness decreased relative to increasing age (p = 0.007) within 4 age groups: 22.8 +/- 5.1 mm (18 to 39 years) to 22.1 +/- 5.1 mm (40 to 59 years) to 21.1 +/- 3.7 mm (60 to 74 years) to 20.8 +/- 3.6 mm (>or=75 years). The LV thickness index (summation of wall thicknesses in all 4 segments) also decreased with age (p = 0.017): 63.0 +/- 12.2 mm to 59.8 +/- 11.9 mm to 58.3 +/- 10.4 mm to 57.9 +/- 9.8 mm. Decreasing magnitude of LV hypertrophy was independently associated with increasing age, but not with other relevant disease variables, such as symptoms and outflow obstruction. However, when separated by gender, this inverse relation between age and LV wall thickness was statistically significant only for women (p = 0.007). In conclusion, in an unselected HC cohort, cross-sectional analysis showed a modest but statistically significant inverse relation between age and LV hypertrophy that was largely gender-specific for women. This association constitutes another facet of the natural history of this complex and heterogenous disease and may reflect disproportionate occurrence of premature death in young patients with HC with marked hypertrophy or possibly gradual LV remodeling.

  18. Gender-divergent profile of bile acid homeostasis during aging of mice.

    Zidong Donna Fu

    Full Text Available Aging is a physiological process with a progressive decline of adaptation and functional capacity of the body. Bile acids (BAs have been recognized as signaling molecules regulating the homeostasis of glucose, lipid, and energy. The current study characterizes the age-related changes of individual BA concentrations by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS in serum and liver of male and female C57BL/6 mice from 3 to 27 months of age. Total BA concentrations in serum increased 340% from 3 to 27 months in female mice, whereas they remained relatively constant with age in male mice. During aging, male and female mice shared the following changes: (1 BA concentrations in liver remained relatively constant; (2 the proportions of beta-muricholic acid (βMCA increased and deoxycholic acid (DCA decreased between 3 and 27 months in serum and liver; and (3 total BAs in serum and liver became more hydrophilic between 3 and 27 months. In female mice, (1 the mRNAs of hepatic BA uptake transporters, the Na(+/taurocholate cotransporting polypeptide (Ntcp and the organic anion transporting polypeptide 1b2 (Oatp1b2, decreased after 12 months, and similar trends were observed for their proteins; (2 the mRNA of the rate-limiting enzyme for BA synthesis, cholesterol 7α-hydroxylase (Cyp7a1, increased from 3 to 9 months and remained high thereafter. However, in male mice, Ntcp, Oatp1b2, and Cyp7a1 mRNAs remained relatively constant with age. In summary, the current study shows gender-divergent profiles of BA concentrations and composition in serum and liver of mice during aging, which is likely due to the gender-divergent expression of BA transporters Ntcp and Oatp1b2 as well as the synthetic enzyme Cyp7a1.

    To assess the associations between gender roles and depression in older men and women and whether gender roles are independent risk factors for depression. International cross-sectional study of adults between 65 and 74 years old (n = 1,967). Depression was defined by a score of 16 or over in the Center for Epidemiologic Studies Depression Scale (CES-D). A validated 12-item Bem Sex Role Inventory (BSRI) was used to classify participants in gender roles (Masculine, Feminine, Androgynous, and Undifferentiated) using research site medians of femininity and masculinity as cut-off points. Poisson regressions were fitted to estimate the prevalence ratios (PR) of depression for each gender role compared to the masculine role, adjusting for sex, sufficiency of income, education, marital status, self-rated health, and chronic conditions. Among men, 31.2% were androgynous, 26% were masculine, 14.4% were feminine, and 28.4% were undifferentiated; among women, the corresponding percentages were 32.7%, 14.9%, 27%, and 25.4%. Both in men and in women, depressive symptoms (CES-D≥16) were more prevalent in those endorsing the undifferentiated type, compared to masculine, feminine or androgynous groups. However, after adjusting for potential confounders, compared to the masculine group only those endorsing the androgynous role were 28% less likely to suffer from depression: PR of 0.72 (95% CI: 0.55-0.93). In fully adjusted models, prevalence rates of depression were not different from masculine participants in the two other gender groups of feminine and undifferentiated. Androgynous roles were associated with lower rates of depression in older adults, independently of being a man or a woman.

    PURPOSE: Several studies have shown that the traditional stereotype of a "good" manager being masculine and male still exists. The recent changes in the proportion of women and female managers in organizations could affect these two managerial stereotypes, leading to a stronger preference for feminine characteristics and female leaders. This study examines if the gender of an employee, the gender of the manager, and the management gender ratio in an organization are related to employees' managerial stereotypes. DESIGN/METHODOLOGY/APPROACH: 3229 respondents working in various organizations completed an electronic questionnaire. FINDINGS: The results confirm our hypotheses that, although the general stereotype of a manager is masculine and although most prefer a man as a manager, female employees, employees with a female manager, and employees working in an organization with a high percentage of female managers, have a stronger preference for feminine characteristics of managers and for female managers. Moreover, we find that proximal variables are much stronger predictors of these preferences than more distal variables. IMPLICATIONS: Our study suggests that managerial stereotypes could change as a result of personal experiences and changes in the organizational context. The results imply that increasing the proportion of female managers is an effective way to overcome managerial stereotyping. ORIGINALITY/VALUE: This study examines the influence on managerial stereotypes of various proximal and distal factors derived from theory among a large group of employees (in contrast to students).

    The aim of this study was to measure the mandibular cortical index (MCI), mental index (MI), panoramic mandibular index (PMI) and cortical bone thickness in the zone of the gonial angle (GT) in panoramic radiographies from a large sample of males and females and to determine how they relate to patients' age, gender and dental status. 910 panoramic radiographs were obtained and grouped into age, dental status and gender. The MCI, MI, PMI and GT were analysed. Remarkable differences were observed for MCI and GT regarding gender, age groups and dental status on both sides (p PMI in females, dental status had an effect on the MI and PMI in males (p PMI (p PMI and MI measurements. The effects of age and tooth loss in the GT and MCI measurements are similar, and these indices can be accepted as more reliable in studies including both genders.

    Full Text Available Serotonin plays a potential role in bone metabolism, but the nature and extent of this relationship is unclear and human studies directly addressing the skeletal effect of circulating serotonin are rare.The study aimed to investigate the associations between serum serotonin and bone traits at multiple skeletal sites in women and men.Subjects were part of the CALEX-family study and comprised 235 young women, 121 premenopausal women, 124 postmenopausal women, and 168 men. Body composition was assessed using DXA, as was areal bone mineral density (aBMD of spine, femur and whole body. In addition, pQCT was used to determine bone properties at tibial midshaft and distal radius. Fasting serum serotonin concentration was assessed using a competitive enzyme-linked immunosorbent assay.Serum serotonin declined with advancing age both in females and males (all p<0.01. Serotonin was negatively correlated with weight, BMI, lean and fat mass in women (r = -0.22 to -0.39, all p<0.001, but positively with height and lean mass in men (all p<0.01. In the premenopausal women, serotonin was negatively correlated with lumbar spine aBMD (r = -0.23, p<0.05 but the statistical significance disappeared after adjustment for weight. Conversely, in postmenopausal women, serotonin was positively correlated with whole body and femur aBMD, as well as with distal radius bone mineral content and volumetric BMD (r = 0.20 to 0.30, all p<0.05, and these associations remained significant after adjustment for weight. In men, no significant associations were found between serotonin and bone traits.Serum serotonin is positively associated with bone traits in postmenopausal women, but not in premenopausal women or men. This partially supports the idea of circulating serotonin playing a role in the regulation of bone metabolism, but also indicates the importance of gender and age specific factors.

    Disorders/differences of sex development (DSD) comprise multiple congenital conditions in which chromosomal, gonadal, and/or anatomical sex are discordant. The prediction of future gender identity (i.e., self-identifying as male, female, or other) in children with DSD can be imprecise, and current knowledge about the development of gender identity in people with, and without DSD, is limited. However, sex of rearing is the strongest predictor of gender identity for the majority of individuals with various DSD conditions. When making decisions regarding sex of rearing biological factors (e.g., possession of a Y chromosome, degree and duration of pre- and postnatal androgen exposure, phenotypic presentation of the external genitalia, and fertility potential), social and cultural factors, as well as quality of life should be considered. Information on gender identity outcomes across a range of DSD diagnoses is presented to aid in sex of rearing assignment. Copyright © 2017 Elsevier Inc. All rights reserved.

    In the second language acquisition, the study focus of linguistics is the influence of age factors which has always been considered as one of the most controversial issues. Some experts hold that the younger the better and would get good compe⁃tence to learn language well, meanwhile others believe that adult have more strong motivation and competence.Based on the Brain Plasticity Theory and the Critical Period Hypothesis, and the intention of this thesis is to reveal such a hypothesis that the younger the learner who starts to learn a second language, the greater performance that he will achieve like a native does, through the comparative research between children and adults. The subjects are 100 Chinese learners who begin learning at different levels and ages. According to the results of integrated scores and a collection of the data in the questionnaire, an analysis show that the results acquired would be consistent with the hypothesis.The intention of this research is not only to argue which is better, earlier or later, but also an trial, through investigation and study, to provide some insights and suggestion to the existent issues, especially the children second language education and college English study in China.

    Cultural values were examined as predictors of suicide incidence rates compiled for men and women in six age groups for 33 nations for the years 1965, 1970, 1975, 1980, and 1985. Hofstede's cultural values of Power-Distance, Uncertainty Avoidance, and Masculinity (i.e., social indifference) were negative correlates of reported suicide, and Individualism was a strong positive correlate. The proportion of variance in suicide reports generally related to these four cultural values was R2 = 0.25. Suicide by women and by middle-aged people was most related to cultural values, even though international variance in suicide is greater for men and for the elderly. Suicide incidence for girls and young women showed unique negative correlations with Individualism. For all age groups, Individualism predicted a greater preponderance of male suicides, and Power-Distance predicted more similar male and female suicide rates. Social alienation and Gilligan's feminist theory of moral judgment were hypothesized to explain some gender differences.

    Full Text Available This study examined two components of understanding TV advertising: the recognition of the difference between programmes and commercials and the comprehension of advertising intent. ANOVA analyses were performed to assess the effect on age, gender, parent-child interaction and parental control over children of TV programme watching. Research found that majority of children aged between five and eight have some understanding of TV advertising, they are capable in differentiate programme and commercials especially if this understanding is measured by non-verbal rather than verbal measure. However, the results based on verbal measures are not as conclusive. The findings also indicated that children age has substantial positive effect on the children understanding of TV advertising. This effect pronounced for verbal measure of comprehension intent for advertisements. Results also showed a small but significant negative effect of parental control of TV viewing, in which a high control of TV viewing result in a relatively low understanding of TV advertising.

    To evaluate the gender-specific impact of social exclusion on the mortality of older Japanese adults, we performed a prospective data analysis using the data of the Aichi Gerontological Evaluation Study (AGES). In AGES, we surveyed functionally independent residents aged 65 years or older who lived in six municipalities in Aichi prefecture, Japan. We gathered baseline information from 13,310 respondents in 2003. Information on mortality was obtained from municipal databases of the public long-term care insurance system. All participants were followed for up to 4 years. We evaluated social exclusion in terms of the combination of social isolation, social inactivity, and relative poverty. Cox's proportional hazard model revealed that socially excluded older people were at significantly increased risk (9-34%) for premature mortality. Those with simultaneously relative poverty and social isolation and/or social inactivity were 1.29 times more likely to die prematurely than those who were not socially excluded. Women showed stronger overall impact of social exclusion on mortality, whereas relative poverty was significantly associated with mortality risks for men. If these associations are truly causal, social exclusion is attributable to 9000-44,000 premature deaths (1-5%) annually for the older Japanese population. Health and social policies to mitigate the issue of social exclusion among older adults may require gender-specific approaches.

    The ability to recursively infer the mental states of others to explain their complex behavior in ambiguous social situation may be called Advanced Theory of Mind (aToM). The relations between two components of aToM, cognitive and affective, measured on a behavioral level in 151 Polish 13-year-olds and 174 16-year-olds was examined. The role of age, gender and friendship style and its relations to the cognitive and affective aToM was explored. Cognitive aToM was only weakly to moderately related to affective aToM. Across both age groups females scored higher than males. Males' aToM abilities did not differ according to age, but they scored higher in the cognitive aToM than affective ToM. Also, different aspects of friendship style were significant predictors of both aToM abilities. The implications for two aToM components within a gendered social context were discussed.

    2016-06-01

    Full Text Available Background: Contemporary multiwork definitely changes its face, and statistics show that Poland is in the forefront of European countries in terms of the number of multiworkers. The question arises whether the provision of work for more than one employer can influence personal and professional satisfaction, and whether job satisfaction, satisfaction with marriage and satisfaction with life are differentiated by sex, gender, age and a job position. Material and Methods: The study involved 218 multiworkers and 218 monoworkers. The subjects completed the following research tools: a survey, the Satisfaction with Life Scale, the Job Description Questionnaire, the Job Affect Scale, the Scale of Masculinity and Femininity. Results: The research shows that multiwork differentiates satisfaction with organization and management. Sex, gender, age and job position affect the whole system of satisfaction dimensions, especially satisfaction with work and with life. Interaction of multiwork and age, sex, and job position differentiate satisfaction with certain aspects of job. Conclusions: The results of the study contribute to the deepening of knowledge about psychosocial functioning of multiworkers and the phenomenon of multiwork. Med Pr 2016;67(3:385–395

    Objective To examine the influence of aging and body-mass-index (BMI) on the oropharynx configuration in male and female Japanese patients. Study design This study examined the computed tomography (CT) images of 19 male and 19 females, group matched for age and BMI. The airway and the soft tissue volumes between the posterior nasal spine and top of the epiglottis were compared. Results The patient's height, total oropharynx length (TOL), and lower oropharynx lengths and volume measurements (soft tissue and airway) demonstrated statistically significant gender differences. Men consistently had larger TOL and volumes than women. In men, TOL changed with age, and age was a significant predictor of lower oropharynx length. In males, the upper oropharynx soft tissue volume decreased significantly with age and lower oropharynx soft tissue volume increased significantly with age. In females no significant relationship was identified. Conclusion The airway lengthens with aging in males and we speculate that it becomes more collapsible, which in turn could contribute to obstructive sleep apnea. PMID:18602313

    The gonad shielding is used to minimize the impact of the exposure to gonads when Abdomen, Plevis and Hip X-ray inspections are conducted on radiation impressionable pediatric patients. By the way, the gonad is palpable difficult and impossible to check visually because it's a sensitive area, so tests are conducted with the approximate location of shielding, thereby appearing problems of not shielding gonads accurately. Accordingly, this study produced shields by age and gender of pediatric patients and studied the method of positioning shields with ASIS as a reference point without palpable sensitive areas, and tried to evaluate its usability. The study surveyed 30 pediatric patients by gender and age, who came and got inspected in Department of Radiology, our hospital from February 2012 to January 2014 and obtained the value of tolerance by measuring the average size of the pelvis using the distance measurement function of Infinitt Piview with the images stored in the PACS and producing shields by age and gender of pediatric patients and specifying the areas at random for the comparative analysis of pre- and post-using. It calculated the technology statistics (mean±SD) with the value of tolerance measured the length using SPSS 12.0 statistical program. As for boys, differences in the tolerance range of pre- and post-using shields were 2.69 mm in case of 1 year old, 2.58 mm in 2 years, 2.37 mm in 3 years, 2.815 mm in 4-5 years, 2.043 mm in 7-10 years, and as for girls,1.92 mm in 1-2 years, 1.75 mm in 3-4 years, 2.52 mm in 5-6 years and 1.93 mm in 7-10. After analyzing the pre- and post-using shields for all of boys and girls, there were statistically significant differences (P<0.050). It is considered that we can minimize the exposure to gonads and get a better video for diagnosis in testing high biological impressionable pediatric, if we use shields correctly with ASIS as a reference point considering its shape and size by age and gender in Abdomen, Plevis

    The aim of this observational study was to investigate the intake of dietary fibre and its sources among Polish adolescents according to prevalence of overweight after adjustment for age and gender. The study sample consisted of 1,565 students, including 48% boys and 52% girls aged 13-18 with normal weight, overweight and obesity. Dietary information was reported using the Block Screening Questionnaire for Fruit/Vegetable/Fibre Intake. The nutritional status was assessed on the basis of body mass and height measurements. The statistical analysis used one-factor logistic regression, multiple linear regression, trend estimation and a comparison of mean values. Adolescents consuming white bread and rolls with a frequency ≥4 times/week had OR=0.74 (95% CI 0.56-0.97) for overweight and obesity compared to adolescents with less frequent consumption. For other fibre sources and overall dietary fibre no significant differences were noted in consumption frequency between adolescents with normal weight and overweight/obesity. Overall, boys were more often overweight and obese than girls. Girls had a higher intake of dietary fibre, fruit, fresh vegetables, dark bread and rolls, and lower intake of potatoes, beans and white bread and rolls than boys. Older age was associated with a decrease in the consumption of fruit juices, fruit, potatoes, white bread and rolls, and dietary fibre in girls and a decrease in fruit and fresh vegetable consumption in boys. The intake of dietary fibre was not associated with the prevalence of overweight. As to the fibre sources, only a higher consumption of white bread and rolls decreased the chance of the occurrence of adolescent overweight. The consumption of dietary fibre and its sources was related to the age and gender of adolescents.

    Emotion processing, supported by frontolimbic circuitry known to be sensitive to the effects of aging, is a relatively understudied cognitive-emotional domain in geriatric depression. Some evidence suggests that the neurophysiological disruption observed in emotion processing among adults with major depressive disorder (MDD) may be modulated by both gender and age. Therefore, the present study investigated the effects of gender and age on the neural circuitry supporting emotion processing in MDD. Cross-sectional comparison of fMRI signal during performance of an emotion processing task. Outpatient university setting. One hundred adults recruited by MDD status, gender, and age. Participants underwent fMRI while completing the Facial Emotion Perception Test. They viewed photographs of faces and categorized the emotion perceived. Contrast for fMRI was of face perception minus animal identification blocks. Effects of depression were observed in precuneus and effects of age in a number of frontolimbic regions. Three-way interactions were present between MDD status, gender, and age in regions pertinent to emotion processing, including frontal, limbic, and basal ganglia. Young women with MDD and older men with MDD exhibited hyperactivation in these regions compared with their respective same-gender healthy comparison (HC) counterparts. In contrast, older women and younger men with MDD exhibited hypoactivation compared to their respective same-gender HC counterparts. This the first study to report gender- and age-specific differences in emotion processing circuitry in MDD. Gender-differential mechanisms may underlie cognitive-emotional disruption in older adults with MDD. The present findings have implications for improved probes into the heterogeneity of the MDD syndrome. Copyright © 2015 American Association for Geriatric Psychiatry. Published by Elsevier Inc.

    Rey's Auditory Verbal Learning Test (AVLT) is widely used to evaluate dysfunctional episodic memory. The current study aimed to provide extended age- and gender-specific norms for the German AVLT for individuals older than 50 years. In 690 subjects, a comprehensive medical examination including a structural 3.0-tesla magnetic resonance imaging scan was administered, as well as extensive neuropsychological tests. After controlling for exclusion criteria, 407 subjects were included in the analysis. AVLT performance decreased with age, and women outperformed men. We present age- and gender-specific normative data for the German AVLT from subjects aged between 50 and 70 years.

  3. A review of problem drinking in young Mexicans and possible correlations with gender-related factors

    Full Text Available Increased alcohol consumption in the Mexican population has lead to serious problems around this addiction. The age of onset of alcohol intake is occurring at younger ages increasingly and first contact with alcohol tends to occur at the beginning of adolescence, a period of life fraught with conflicts. In some cases, the teenager will seek evasion or refuge in drinking, or social acceptance from peers and peer groups. In this critical phase, the individual is trying to forge his or her own identity and tends to rebel against figures of authority. All of this leads to a variety of behaviors that many times disregard possible consequences on oneself, one’s family and one’s community. By adopting a gender perspective, this article attempts to provide some insight as to how men and women develop problem-drinking, factors that may bear an effect on its occurrence, as well as to highlight some actions points that may help to solve and prevent this adverse problem.

    The more recent use of ultrasound scanning allows a direct measurement on unmodified skin, and is considered to be a reliable method for in vivo measurement of epidermal and dermal thickness. The objective of this study was to assess the influence of gender and age on the thickness and echo-density of skin measured by high frequency ultrasonography (HFUS). This study was carried out on 30 healthy volunteers (17 female, 13 male) with age range of 24-61 years old. The thickness and echo-density of dermis as well as epidermal entrance echo thickness in five anatomic sites (cheek, neck, palm, dorsal foot, and sole) were measured using two different types of B mode HFUS, 22 and 50 MHz frequencies. The epidermal entrance echo thickness and thickness of dermis in males were higher than females, which was statistically significant on neck and dorsum of foot. The echo-density of dermis was higher in females on all sites, but was only statistically significant on neck. The epidermal entrance echo thickness and thickness of dermis in young age group was statistically higher than old group on sole and dorsal of the foot respectively. Overall, the skin thickness decreased with age. High frequency ultrasonography method provides a simple non-invasive method for evaluating the skin thickness and echo-density. Gender and age have significant effect on these parameters. Differences in study method, population, and body site likely account for different results previously reported. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Neuroanatomical differences attributable to aging and gender have been well documented, and these differences may be associated with differences in behaviors and cognitive performance. However, little is known about the dynamic organization of anatomical connectivity within the cerebral cortex, which may underlie population differences in brain function. In this study, we investigated age and sex effects on the anatomical connectivity patterns of 95 normal subjects ranging in age from 19 to 85 years. Using the connectivity probability derived from diffusion magnetic resonance imaging tractography, we characterized the cerebral cortex as a weighted network of connected regions. This approach captures the underlying organization of anatomical connectivity for each subject at a regional level. Advanced graph theoretical analysis revealed that the resulting cortical networks exhibited "small-world" character (i.e., efficient information transfer both at local and global scale). In particular, the precuneus and posterior cingulate gyrus were consistently observed as centrally connected regions, independent of age and sex. Additional analysis revealed a reduction in overall cortical connectivity with age. There were also changes in the underlying network organization that resulted in decreased local efficiency, and also a shift of regional efficiency from the parietal and occipital to frontal and temporal neocortex in older brains. In addition, women showed greater overall cortical connectivity and the underlying organization of their cortical networks was more efficient, both locally and globally. There were also distributed regional differences in efficiency between sexes. Our results provide new insights into the substrates that underlie behavioral and cognitive differences in aging and sex.

The decrease of G-SH levels in male groups could be attributed to stabilizing the redox status of protein thiol groups by the depletion of the GSH groups. Considering the results, the renal tissue proteins and lipids in different genders may have different susceptibilities to oxidative damage.

    Full Text Available Abstract Background In the United States, nearly half of high school students are sexually active, and adolescents experience high rates of unintended pregnancy and sexually transmitted diseases. Parents can have an important influence on their children's sexual behaviour, but many parents do not talk with their children about sexual topics. Research has shown significant differences in parent-child communication about sexual topics depending on the gender of both the parent and the child. Little is known, however, about the reasons for these gender differences. The purpose of this paper is to describe how factors associated with parent-child communication about sexual topics differ by gender. Methods Data are from a nationwide online survey with 829 fathers and 1,113 mothers of children aged 10 to 14. For each of the four gender groups (fathers of sons, fathers of daughters, mothers of sons, mothers of daughters, we calculated the distribution of responses to questions assessing (1 parent-child communication about sex-related topics, and (2 factors associated with that communication. We used chi-square tests to determine whether the distributions differed and the false discovery rate control to reduce the likelihood of type I errors. Results With both sons and daughters, fathers communicated less about sexual topics than mothers did. Fathers also had lower levels of many characteristics that facilitate communication about sex (e.g., lower self-efficacy and lower expectations that talking to their children about sex would have positive outcomes. Compared with parents of sons, parents of daughters (both mothers and fathers talked more about sexual topics, were more concerned about potential harmful consequences of sexual activity, and were more disapproving of their child having sex at an early age.

    The objective of the study is to examine the effects of age and gender on finger coordination. Twelve young (24 +/- 8 yr; 6 men and 6 women) and 12 elderly (75 +/- 5 yr; 6 men and 6 women) subjects performed single-finger maximal contraction [maximal voluntary contraction (MVC)], four-finger MVC, and four-finger ramp force production tasks by pressing on individual force transducers. A drop in the force of individual fingers during four-finger MVC tasks compared with single-finger MVC tasks (force deficit) was larger, whereas unintended force production by other fingers during single-finger MVC tasks (enslaving) was smaller, in elderly than in young subjects and in women than in men. Force deficit was smaller and enslaving was larger in subjects with higher peak force. During the ramp task, the difference between the variance of total force and the sum of variances of individual forces showed a logarithmic relation to the level of total force, across all subject groups. These findings suggest that indexes of finger coordination scale with force-generating capabilities across gender and age groups.

    Oxidative stress (OS) impairs organic function and is considered causally related to cellular senescence and death. This study aims to evaluate if the redox balance varies in relation to age and gender in healthy cats. To quantify the oxidative status of this species we determined the oxidative damage as serum reactive oxygen metabolites (ROM) and the total serum antioxidant capacity (SAC). In addition, we used the ratio of ROM to SAC as a measure of the oxidative balance, with higher values meaning higher oxidative stress (oxidative stress index). Our results suggest that the male population is at oxidative risk when compared with females, especially between the age of 2 and 7 years. Nutritional strategies in this population looking for additional antioxidant support would probably avoid the oxidative stress status that predisposes to chronic processes in senior male cats. Further clinical trials in this field are recommended.

    Full Text Available This research is set in the context of tourism marketing and refers specifically to tourist roles. A representative sample of 1675 tourists brings to light the tourist role preference in Greece, and allows us to examine the possible differences between men and women of varying ages. The Tourist Role Preference Scale (TRPS was used for this research. The findings of this study support the existence of Yiannakis and Gibson’s 15 leisure tourist roles in Greece. Sun lover, anthropologist, archaeologist, independent mass tourist and escapist were found to be the most prevalent tourist roles in Greece. A comparison between gender and age revealed more similarities than differences. TRPS was proven reliable and valid for the sample used in this study and the questions of the scale represented significantly the tourist roles measured.

    It has been argued that many human behaviors follow predictable developmental patterns, or stages. The FIRO-BC was given to 9- through 13-year-old children (n = 282) to test for a stage-like progression in interpersonal behavior development. The data presented here failed to evidence an age-related progression. However, gender differences did appear in 11-year-olds and increased dramatically by age 13. Geographical differences were found in that the present data differed significantly from the normative data presented in the FIRO manual. The data also support the notion that, at least within the southern population tested. interpersonal behavior may be more related to puberty than has been previously supposed.

    (20–34, mean age = 24.6 ± 3.5 years, ten female) and twenty elderly (65–88, mean age = 73.7 ± 6.6 years, ten female) healthy volunteers were compared. Mini-Mental State Examination (MMSE 28–30) assessed intact cognitive functioning. Pain thresholds were assessed together with the sensory intensity....... Conversely, the intensity and unpleasantness of the pain stimulus were significantly rated lower in the elderly as compared with the young. No gender differences were observed in the report of intensity and unpleasantness of the stimulations. Discussion: a mismatch in pain sensitivity, tolerance, and pain...... self-reports was observed. Findings suggest that pain experiences in the elderly differ from the experiences in the young on multiple dimensions: sensory, affective, and cognitive. Findings may also indicate that the elderly appraise pain experiences using different psychological strategies....

    In Turkey, the discussions in the modern sense about disaster management begun after the 1992 Erzincan and the 1995 Dinar earthquakes, faulting in terms of features and effects. These earthquakes are "Urban Earthquakes'' with effects and faulting charectristics, and have led to radical changes in terms of disaster and disaster management. Disaster Management, to become a science in the world, but with the 1999 Izmit and Duzce earthquakes in Turkey has begun to take seriously on the agenda. Firstly, such as Civil Defense and Red Crescent organizations, by transforming its own, have entered into a new organizing effort. By these earthquakes, NGO's have contributed the search-rescue efforts in the field and to the process of normalization of life. Because "the authority and responsibilities" of NGO's could not be determined, and could not be in planning and scenario studies, we faced the problems. Thus, to the citizens of our country-specific "voluntary" has not benefited enough from the property. The most important development in disaster management in 2009, the Disaster and Emergency Management Presidency (AFAD) has been the establishment. However, in terms of coordination and accreditation to the target point has been reached yet. Another important issue in disaster management (need to be addressed along with disaster actors) is the role of women in disasters. After the Golcuk Earthquake, successful field works of women and women's victimization has attracted attention in two different directions. Gender-sensitive policies should be noted by the all disaster actors due to the importance of the mitigation, and these policies should take place in laws, regulations and planning.

    Full Text Available Purpose: To determine the impact of age and gender on the clinicopathological characteristics of histologically confirmed bladder cancer in India. Materials and Methods: From January 2001 to June 2008, records of patients with bladder cancer were evaluated for age and gender at presentation, clinical symptoms, cystoscopic finding, history of smoking, and histopathological characteristics. A total of 561 patients were identified from the computer-based hospital information system and the case files of patients. Results: A total of 97% of the patients presented with painless hematuria. The mean age was 60.2 ± 4.4 years old (range: 18-90 years old and the male to female ratio was 8.6:1. Transitional cell carcinoma (TCC was the most common histological variety, which was present in 97.71% (470 of 481 of the patients. A total of 26% of the patients had muscle invasive disease at the time of presentation. However, 34.5% (166 of 481 of the patients did not show any evidence of detrusor muscle in their biopsy specimen. In patients with nonmuscle-invasive bladder carcinoma, 55% had p Ta while 45% had p T1. Overall, 44.7% (215 of 481 of the patients had low-grade disease. Among patients younger than 60 years old, low-grade (51.0% vs. 38.1%; P = 0.006 and low-stage (77.1% vs. 70.8%; P = 0.119 disease were more prevalent than in patients older than 60 years old. The incidence of smoking was much higher among males compared with females (74% vs. 22%. Conclusion: TCC is the predominant cancer, with significant male preponderance among Indian patients. Younger-aged patients have low-grade disease. Hematuria is the most common presentation and greater awareness is needed not to overlook bladder cancer.

    This article presents the normative data for flow density measured using optical coherence tomography (OCT) angiography and the impact of age and gender is evaluated. In this study 58 eyes from 58 healthy volunteers with no history of any ocular disease or ocular surgery were included. The OCT angiography imaging was performed using the RTVue XR Avanti with the AngioVue (Optovue, Fremont, CA). The macula was imaged using a 3 × 3 mm scan, and the flow density data in the superficial retinal OCT angiogram and deep retinal OCT angiogram were extracted and analyzed. The groups were compared using the Mann-Whitney U‑test and the degree of correlation between two variables was expressed as the Spearman's correlation coefficient (rSp.) RESULTS: The mean subject age was 38.3 ± 14.6 years. The flow density (whole en face) in the deep retinal OCT angiogram was significantly higher compared to the flow density in the superficial retinal OCT angiogram (p density in superficial and deep OCT angiograms of the macula between males (n = 27) and females (n = 31). There was a significant correlation between the flow density in the deep retinal OCT angiogram and age (rSp. = -0.41, p = 0.001). Whereas gender has no impact on the flow density measured using OCT angiography, there was a significant correlation between the flow density in the deep retinal OCT angiogram and age.

    Pharmacokinetics of the benzodiazepine bromazepam were evaluated in volunteer subjects who received single 6 mg oral doses followed by blood sampling during the next 48 hours. Age and gender effects were studied in 32 subjects, divided into young (aged 21 to 29 years) and elderly (aged 60 to 81 years) groups. Compared with young subjects, the elderly had significantly higher peak serum bromazepam concentrations (132 vs. 82 ng/ml), smaller volume of distribution (0.88 vs. 1.44 L/kg), lower oral clearance (0.41 vs. 0.76 ml/min/kg), and increased serum free fraction (34.8% vs. 28.8% unbound). However, gender had no significant influence on bromazepam kinetics. In 11 young female users of oral contraceptive steroids, compared with seven age- and weight-matched control women not using oral contraceptives, no differences in bromazepam kinetics were observed. Coadministration of cimetidine (1.2 gm daily) significantly reduced bromazepam clearance (0.41 vs. 0.82 ml/min/kg) and prolonged elimination half-life (29 vs. 23 hours). Propranolol (160 mg daily) significantly prolonged bromazepam half-life (28 vs. 23 hours), but the reduction in clearance associated with propranolol (0.65 vs. 0.82 ml/min/kg) did not reach significance. Bromazepam has the pharmacokinetic characteristics of benzodiazepines with half-life values between 20 and 30 hours. Consistent with its biotransformation pathway by hepatic microsomal oxidation, bromazepam clearance is significantly impaired in elderly individuals, by coadministration of cimetidine and possibly propranolol.

    Measurement of bone turnover in conditions such as osteoporosis has been limited by the need for invasive iliac bone biopsy to reliably determine parameters of bone metabolism. Recent advances in the area of serum and urinary markers of bone metabolism have raised the possibility for noninvasive measurements; however, little nonhuman primate data exist for these parameters. The purpose of this experiment was to define the normal range and variability of several of the newer noninvasive bone markers which are currently under investigation in humans. The primary intent was to determine age and gender variability, as well as provide some normative data for future experiments in nonhuman primates. Twenty-four rhesus macaques were divided into equal groups of male and female according to the following age groupings: 3 years, 5-10 years, 15-20 years, and > 25 years. Urine was collected three times daily for a four-day period and measured for several markers of bone turnoverm including pyridinoline (PYD), deoxypyrodinoline (DPD), hydroxyproline, and creatinine. Bone mineral density measurements of the lumbar spine were performed at the beginning and end of the study period. Serum was also obtained at the time of bone densitometry for measurement of osteocalcin levels by radioimmunoassay. There were no significant differences in bone mineral density, urine PYD, or urine DPD based on gender. Bone density was lowest in the youngest animals, peaked in the 15-20-year group, but again decreased in the oldest animals. The osteocalcin, PYD, and DPD levels followed an inversely related pattern to bone density. The most important result was the relative age insensitivity of the ratio of PYD:DPD in monkeys up to age 20 years. Since bone density changes take months or years to become measurable and iliac biopsies are invasive, the PYD/DPD marker ratio may have important implications for rapid noninvasive measurement of the effects of potential treatments for osteoporosis in the non

    This study assessed health-related quality of life (HRQoL) reported by overweight adolescents and compared to their parent-proxy perception of HRQoL, according to adolescent gender, adolescent age, and parent gender. Patients and a total of 179 adolescents aged 10 to 18 years with excess weight were evaluated for perceived HRQoL prior to beginning a weight-loss intervention, using the Pediatric Quality of Life Inventory (PedsQL 4.0) questionnaire, estimating quality of life in the physical, emotional, social, and school domains, as well as index measures of psychosocial and overall quality of life. Parents completed the same questionnaire estimating his or her child's HRQoL. Compared to their child's self-report, parents underestimated all the domains of HRQoL except the school domain. Parents underestimated all the domains of HRQoL among boys; however, they only underestimated the physical domain among girls. Comparisons between parent-proxy perception and self-report of the adolescent according to adolescent's age revealed that parents underestimated their children's HRQoL in the younger adolescents (10 to 13 years) for all except for the school domain and underestimated only the physical domain in older adolescents (14 to 18 years). The same comparison between parent-proxy perception and their child's self-report of HRQoL according to parent gender showed that mothers underestimated HRQoL in all domains except for the school domain, while fathers only underestimated the school domain. The differences between self-report of overweight adolescent and perceptions of their parents about the HRQoL of their children are influenced by adolescent gender and age and parent gender.

    Recent epidemiological data suggest the relation between hearing difficulty and depression is more evident in younger and middle-aged populations than in older adults. There are also suggestions that the relation may be more evident in specific subgroups; that is, other factors may influence a relationship between hearing and depression in different subgroups. Using cross-sectional data from the UK Biobank on 134,357 community-dwelling people and structural equation modelling, this study examined the potential mediating influence of social isolation and unemployment and the confounding influence of physical illness and cardiovascular conditions on the relation between a latent hearing variable and both a latent depressive episodes variable and a latent depressive symptoms variable. The models were stratified by age (40s, 50s, and 60s) and gender and further controlled for physical illness and professional support in associations involving social isolation and unemployment. The latent hearing variable was primarily defined by reported hearing difficulty in noise. For all subgroups, poor hearing was significantly related to both more depressive episodes and more depressive symptoms. In all models, the direct and generally small association exceeded the indirect associations via physical health and social interaction. Significant (depressive episodes) and near significant (depressive symptoms) higher direct associations were estimated for males in their 40s and 50s than for males in their 60s. There was at each age-group no significant difference in estimated associations across gender. Irrespective of the temporal order of variables, findings suggest that audiological services should facilitate psychosocial counselling. PMID:28752806

    érent selon les âges et le sexe, avec des particularités qui sont expliquées en détailThe purpose of this article is to present the results of research into how gender and age affect stress levels in teachers. The initial hypothesis is that there is a strong link between age, sex and stress level. The sample used to conduct the study came from GRELDO, the research group into professional stress factors for teachers, in the educational psychology section of the official college of psychologists of Catalonia. It includes 1,018 professionals who answered the questionnaire drawn up with a list of 57 stress factors in teaching. The gender proportions were within the usual parameters in the educational world: approximately 75% women and 25% men. By means of univariate factorial analysis of variance, the overall conclusion was reached that the level of stress is significantly different depending on age and depending on sex, with specific features which are explained in detailEl propósito de este artículo es presentar los resultados de una investigación sobre cómo afecta el género y la edad en el nivel de estrés de los docentes. La hipótesis de salida es que hay bastante relación entre edades, sexo y nivel de estrés.

    The palatal masticatory mucosa is widely used as donor material for periodontal plastic surgery. The thickness of graft tissue is important for graft survival. We investigated the thickness of palatal mucosa using a bone sounding technique. We also examined the relation of age and gender to the thickness of palatal mucosa. Fifty healthy subjects were divided into a younger age group of 25 subjects, 14-21 years old (mean, 19 years); the older age group consisted of 25 subjects, 30-59 years old (mean, 34.4 years). A bone sounding method using a periodontal probe and endodontic spreader no. 60 was used to assess the thickness of palatal mucosa at 15 pre-determined sites defined according to the gingival margin and palatal lines. Student's 't' test was used to validate differences in mucosal thickness between the groups. The mean thickness of palatal masticatory mucosa ranged from 2.5 to 3.7 mm. The younger age group had a thinner mucosa than the older age group and females had a thinner mucosa than males. The canine and premolar areas appeared to be the most appropriate donor sites for grafting procedures.

    2010-01-01

    This contribution is a reply to Dr. Månsdotter's comments on our discussion paper 'Health and well-being in old age: the pertinence of a gender mainstreaming approach in research' published in Gerontology [Gerontology 2010 (in press)]. Even though the comments are interesting and comprehensible, they cannot be left unanswered, this primarily because they are based on weak empirical evidence. (1) It is broadly uncontested that gender is not static. However, the conclusion that the more egalitarian division of parental duties can be viewed as an indicator for reduction of the gender gap in longevity and health is highly speculative. There is not enough empirical evidence to substantiate this position. (2) The 'caring hypothesis' proposed by Månsdotter, which holds that caring fathers develop less risky lifestyles and increased worries, is a possible, but not a sufficient explanation for gender convergence of physical and psychological health in future generations. Such a convergence seems to be heavily co-determined by the changing lifestyles of women. (3) From a lifespan developmental perspective, androgyny does not mean gender equality, but a necessary openness of an individual for the positive traits of the opposing gender role, an essential trait for successful ageing. (4) Månsdotter's doubts concerning the implementation of gender mainstreaming in gerontological research and practice because of society's limited resources are not comprehensible. Exactly because economical resources are limited, and exactly because men and women have different resources and disadvantages due to their specific bio-psycho-social realities, the most efficient way of dealing with the gender gaps in health is with a differentialapproach. (5) The concluding recommendation of Månsdotter for more openness as a scientific position regarding the impact of gender roles on human health and well-being stands in contrast to her claim for normative standpoints and prioritization of either

    Full Text Available The aim of this study was to test effects of age, gender, and sire line on dairy cattle behaviour. We have analyzed results of ethological tests for 40 Holstein breed animals (23 males and 17 females, offsprings of three sires. Maintenance behaviour were observed at the age of 90, 130 and 170 days. Behaviour in the maze was conducted at the age of 119 days, an open-field test was applied at the age of 124, 168, and 355 days. The social behaviour was determined by feeding on 155th day of the age. The times and the number of periods in all activities of maintenance behaviour were changing significantly (P<0.001 according to the age. The total time of lying, lying with ruminating, ruminating, feeding was increasing from the age of 90 days to the age of 170 days, on the other hand the time of standing was decreasing. The times of total lying, lying with ruminating, total ruminating, feeding were increased, and time of standing was decreased from the age of 90 days to the age of 170 days. Calves spent more time lying on the left side than on the right side. The number of ruminating periods was increasing according to the age. Eating periods were decreasing from the age of 90 to 170 days. The most of lying periods were recorded at the age of 130 days. The differences between sex were found in total time of lying, lying on the right side (P<0.05, and the males rest longer and had more periods of lying than females. We have found differences in times of feeding (P<0.001, total lying, standing (P<0.01, and lying on the left side (P<0.05 according to sire by comparing behaviour of the calves. Sire genotypes were significantly manifested in period number of total lying (P<0.001, lying on the right side, feeding (P<0.01, and standing (P<0.05. Males stood in the first part of maze longer than females (P<0.001, also length of total standing was longer by bulls (P<0.01. Heifers took shorter time to leave the maze than bulls (P<0.05.

    Full Text Available Abstract Background Physical activity (PA is part of a healthy lifestyle and prevents many chronic health problems, in addition to promoting mental health. PA performed outdoors has been found particularly good for promoting one's well-being. The aim of this study was to investigate the extent to which outdoor recreational PA was carried out during 1 year, and the factors influencing such activities from a gender perspective among persons ≥ 60 years of age. Methods This study included 999 individuals 60-96 years of age living in the south eastern part of Sweden. Data collection was carried out during the years of 2001-2003. We measured the amount of regular light and/or intense outdoor recreational PA performed during the last year and determined the probability of performing PA as a function of 10 variables covering individual and socioeconomic factors. Results Our results suggest that being independent physically and healthy enough to manage one's personal hygiene and having access to areas for country walks were the most important factors associated with the probability of engaging in outdoor recreational PA for both men and women. Despite the level of performance being almost equal for the sexes as two-thirds of both had performed outdoor recreational PA during the preceding year more factors, i.e., living alone, being unable to cover an unexpected cost, fear of being violated, and fear of falling, were associated with the possibilities of engaging in outdoor recreational PA among women. Also increasing age seems to affect activities among women negatively to a higher extent than men. Conclusion Men and women seem to have different opportunities and needs with respect to performing PA. These considerations do not seem to be sufficiently taken into account today and improvements could be made concerning e.g., health-promoting activities suggested to the elderly by healthcare personnel and spatial planning within society.

    Much research has examined gender and age effects on compensation, concluding that a wage gap exists favoring men and negative stereotypes against older workers persist. Although the effect of an employee's gender or age has been widely studied, little work has examined the impact of the demographic characteristics of a focal employee's immediate referent groups (e.g., subordinates, peers, or supervisors) on pay. The effect of the gender and age composition of a focal manager's subordinates, peers, and supervisor on the manager's compensation levels was investigated in a sample of 2,178 managers across a wide range of organizations and functional areas. After controlling for a number of human capital variables, results indicated that not only does a wage gap favoring men exist, but also managerial pay is lower when managers' referent groups are largely female, when subordinates are outside the prime age group, and when peers and supervisors are younger.

    This study was conducted to determine factors that promote success in an introductory college computer science course and to determine what, if any, differences appear between genders on those factors. The model included math background, attribution for success/failure, self-efficacy, encouragement, comfort level in the course, work style preference, previous programming experience, previous non-programming computer experience, and gender as possible predictive factors for success in the computer science course. Subjects included 105 students enrolled in an introductory computer science course. The study revealed three predictive factors in the following order of importance: comfort level (with a positive influence), math background (with a positive influence), and attribution to luck (with a negative influence). No significant gender differences were found in these three factors. The study also revealed that both a formal class in programming (which had a positive correlation) and game playing (which had a negative correlation) were predictive of success. The study revealed a significant gender difference in game playing with males reporting more experience with playing games on the computer than females reported.

    Effects of gender and age on structural brain asymmetry were studied by 3D texture analysis in 380 adults. Asymmetry is detected by comparing the complex 3D gray-scale image patterns in the left and right cerebral hemispheres as revealed by anatomical T1-weighted MRI datasets. The Talairach and Tournoux parcellation system was applied to study the asymmetry on five levels: the whole cerebrum, nine coronal sections, 12 axial sections, boxes resulting from both coronal and axial subdivisions, and by a sliding spherical window of 9 mm diameter. The analysis revealed that the brain asymmetry increases in the anterior-posterior direction starting from the central region onward. Male brains were found to be more asymmetric than female. This gender-related effect is noticeable in all brain areas but is most significant in the superior temporal gyrus, Heschl's gyrus, the adjacent white matter regions in the temporal stem and the knee of the optic radiation, the thalamus, and the posterior cingulate. The brain asymmetry increases significantly with age in the inferior frontal gyrus, anterior insula, anterior cingulate, parahippocampal gyrus, retrosplenial cortex, coronal radiata, and knee region of the internal capsule. Asymmetry decreases with age in the optic radiation, precentral gyrus, and angular gyrus. The texture-based method reported here is based on extended multisort cooccurrence matrices that employ intensity, gradient, and anisotropy features in a uniform way. It is sensitive, simple to reproduce, robust, and unbiased in the sense that segmentation of brain compartments and spatial transformations are not necessary. Thus, it should be considered as another tool for digital morphometry in neuroscience.

    Situational Judgement Tests (SJTs) are increasingly implemented in medical school admissions. In this paper, we investigate the effects of vocational interests, previous academic experience, gender and age on SJT performance. The SJT was part of the selection process for the Bachelor's degree programme in Medicine at University of Groningen, the Netherlands. All applicants for the academic year 2015-2016 were included and had to choose between learning communities Global Health (n = 126), Sustainable Care (n = 149), Intramural Care (n = 225), or Molecular Medicine (n = 116). This choice was used as a proxy for vocational interest. In addition, all graduate-entry applicants for academic year 2015-2016 (n = 213) were included to examine the effect of previous academic experience on performance. We used MANCOVA analyses with Bonferroni post hoc multiple comparisons tests for applicant performance on a six-scenario SJT. The MANCOVA analyses showed that for all scenarios, the independent variables were significantly related to performance (Pillai's Trace: 0.02-0.47, p < .01). Vocational interest was related to performance on three scenarios (p < .01). Graduate-entry applicants outperformed all other groups on three scenarios (p < .01) and at least one other group on the other three scenarios (p < .01). Female applicants outperformed male applicants on three scenarios (p < .01) and age was positively related to performance on two scenarios (p < .05). A good fit between applicants' vocational interests and SJT scenario was related to better performance, as was previous academic experience. Gender and age were related to performance on SJT scenarios in different settings. Especially the first effect might be helpful in selecting appropriate candidates for areas of health care in which more professionals are needed.

    In searching for the social and cognitive antecedents of risky online behaviors, some studies have relied on the theory of planned behavior. According to the theory, three components serve as predictors of a given behavior-attitudes toward the behavior (beliefs that people hold about a given behavior), subjective norms (perceptions of what significant others think about the behavior) and perceived behavior control (perceptions about the ease or difficulty of engaging in a particular behavior). However, none of these studies considered the possibility that these factors work differently for boys and girls. We constructed models of the possible antecedents (attitudes, subjective norms and perceived behavior control) of risky behavior online and tested them using a representative sample of 495 sixth to eleventh grade students (46 % female) in a large city in Israel. We measured risky behavior online with items indicating the frequency of posting personal details, sending an insulting message and meeting face-to-face with a stranger met online. Structural equation modeling revealed that peers' subjective norms (beliefs that friends approve of engaging in risky online behaviors), parents' subjective norms (beliefs that parents accept involvement in risky online behaviors) and perceived behavior control were related to boys' risky behavior online, whereas for girls, only parents' subjective norms had such an association. Expanding the models to include other factors underscored that family factors were most strongly associated with girls' risky behavior online.

    Full Text Available Until 2030 the ulcer mortality will have a growing trend as estimated by the World Health Organization. Detection of countries and population groups with high risks for the ulcer mortality is possible using forecast method. The authors made a forecast of mortality rate from complicated ulcer disease in males and females and their age groups (15-24, 25-34, 35-54, 55-74, over 75, 15 - over 75 in our country. The study included data of the World Health Organization Database from 1991 to 2012. The work analyzed absolute all-Ukrainian numbers of persons of both genders died from the ulcer causes (К25-К27 coded by the 10th International Diseases Classification. The relative mortality per 100 000 of alive persons of the same age was calculated de novo. The analysis of distribution laws and their estimation presents a trend of growth of the relative mortality. A remarkable increase of deaths from the ulcer disease is observed in males and females of the age after 55 years old. After the age of 75 years this trend is more expressed.
