Exploring older people's evocation of their positive experiences of aging has been proposed as a counterweight to the Western stereotype of aging as a process of decline. The aim of this article is to explore how aging women, who participate regularly in group exercise classes, perceive their own bodies and the bodies of others. This article reports on the findings from interviews with 16 women between the age of 70 and 85. We analyzed the data using qualitative content analysis. Two overarching and interrelated themes concerning body perception emerged from the interviews: "The aging body and appearance" and "The body as subject and object." The binary discourse of old age, as either a decline or a success appears in our findings. The training contributes to a sense of well-being experienced through perceived increased physical abilities, self- image and self-esteem. Physical ability was perceived as being more important than appearance by the participants in this study, considering their preconception of an association between declining health, abilities, and older age. Involvement in physical activity appears to play a significant role in the perception of the women's own aging. Although physical attractiveness is a desirable outcome, the most important positive impact of the group exercise was related to increased social belonging and well-being, physical abilities, and capabilities. Thus implications for practice suggests that an intensive group training contributes to the opinion that an aging body is not necessarily a barrier to positive and successful aging.

This study investigated the effects of two parental socio-economic characteristics, education and income, on growth and risk of obesity in children from birth to 8 years of age. Longitudinal growth data and national register-based information on socio-economic characteristics were available for 3,030 Swedish children. The development of body mass index (BMI) and height was compared in groups dichotomised by parental education and income. Low parental education was associated with a higher BMI from 4 years of age, independent of income, immigrant background, maternal BMI and smoking during pregnancy. Low family income was associated with a lower birthweight, but did not independently predict BMI development. At 8 years of age, children from less educated families had a three times higher risk of obesity, independent of parental income. Children whose parents had fewer years of education but high income had significantly higher height than all other children. Parental education protected against childhood obesity, even after adjusting for income and other important parental characteristics. Income-related differences in height, despite similar BMIs, raise questions about body composition and metabolic risk profiles. The dominant role of education underscores the value of health literacy initiatives for the parents of young children. ©2018 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

"I Have to Listen to This Old Body": Femininity and the Aging Body.

This study explores how older women with low socioeconomic status living in rural Tanzania give meaning to their (aging) body in relation to the ideals of femininity. Ten qualitative in-depth interviews and 10 focus group discussions (N = 60) were conducted among women aged 60 and older. The findings reveal that older women perceive their aging body as "a burden." This characterization of the body is linked to the inability of the aging body to live up to the women's gendered lives. The conflict between their physical limitations and the desire to perform gendered tasks (internalized feminine habitus) affect the women's process of self-identification. This led to emotional distress and subsequently threatened their survival and well-being. The results suggest that older women need to be supported through interventions that are tailored to their cultural and socioeconomic context. © The Author 2017.

A significant proportion of human communication is nonverbal. Although the fields of business and psychology have significant literature on effectively using body language in a variety of situations, there is limited literature on effective body language for medical educators. To provide 12 tips to highlight effective body language strategies and techniques for medical educators. The tips provided are based on our experiences and reflections as clinician-educators and the available literature. The 12 tips presented offer specific strategies to engage learners, balance learner participation, and bring energy and passion to teaching. Medical educators seeking to maximize their effectiveness would benefit from an understanding of how body language affects a learning environment and how body language techniques can be used to engage audiences, maintain attention, control challenging learners, and convey passion for a topic. Understanding and using body language effectively is an important instructional skill.

Embodying positive aging and neoliberal rationality: Talking about the aging body within narratives of retirement.

PubMed

Laliberte Rudman, Debbie

2015-08-01

Within contemporary Western contexts, positive aging discourses are a key aspect of structured mandates for how to think about and act toward aging bodies. This study adds to previous work on embodiment that has situated how aging bodies are managed by focusing on the body as an aspect of retirement preparation, and critically considering how the imperative to govern the aging body in ways consistent with being a 'good' neoliberal citizen circulated through positive aging discourses is negotiated by aging individuals. Utilizing narrative data from a study addressing the discursive re-shaping and narrative negotiation of retirement within the Canadian context conducted with 30 informants aged 45 to 83, this paper draws upon a governmentality perspective to critically analyze ways informants talked about their aging bodies as part of preparing for and moving into retirement. Overall, the findings illustrate how informants embodied positive aging discourses and, in turn, embodied neoliberal rationality particularly in taking up the call to attend to the body as part of the broadening of retirement planning within a neoliberal context in which health, social, financial and other responsibilities are increasingly shifted toward individuals. Although informants described realizing some of the promises offered up with positive aging discourses, such as a sense of youthfulness and bodily control, their narratives also point to detrimental individual and social implications that can arise out of the limits of bodily practices, the need for perpetual risk management, an aversion to oldness, and attributions of failure. As such, this study raises concerns about the implications of the intersections of positive aging discourses and the neoliberal agenda of activation, responsibilization and individualization.

Self-objectification, habitual body monitoring, and body dissatisfaction in older European American women: exploring age and feminism as moderators.

PubMed

Grippo, Karen P; Hill, Melanie S

2008-06-01

This study examined the influence of feminist attitudes on self-objectification, habitual body monitoring, and body dissatisfaction in middle age and older women. The participants were 138 European American heterosexual women ranging in age from 40 to 87 years old. Consistent with previous research, self-objectification and habitual body monitoring were positively correlated with body dissatisfaction and, self-objectification and habitual body monitoring remained stable across the lifespan. While age did not moderate the relationship between self-objectification and body dissatisfaction, age was found to moderate the relationship between habitual body monitoring and body dissatisfaction such that the relationship was smaller for older women than for middle-aged women. Interestingly, feminist attitudes were not significantly correlated with body dissatisfaction, self-objectification, or habitual body monitoring, and endorsement of feminist attitudes was not found to moderate the relationship between self-objectification or habitual body monitoring and body dissatisfaction. Potential implications for older women are discussed.

2017-07-01

Aging affects almost all physiological processes, but changes in body composition and body phenotype are most observable. In this review, we focus on these changes, including loss of bone and muscle and increase in body fat or redistribution of the latter, possibly leading to osteosarcopenic obesity syndrome. We also address low-grade chronic inflammation, prevalent in aging adults and a cause of many disorders including those associated with body composition. Changes in dietary intake and nutritional requirements of older individuals, that all may lead to some disturbances on tissue and organ levels, are discussed as well. Finally, we discuss the hormonal changes in the aging body, considering each of the tissues, bone, muscle and fat as separate endocrine organs, but yet in the continuous interface and communication with each other. Although there are still many unanswered questions in this field, this review will enable the readers to better understand the aging human body and measures needing to be implemented toward reducing impaired health and disability in older individuals. © 2017 Society for Endocrinology.

Race, embodiment and later life: Re-animating aging bodies of color.

PubMed

Rajan-Rankin, Sweta

2018-06-01

This theoretical essay examines the intersections between race, ethnicity and old age from an inter-disciplinary lens. Drawing on cultural gerontology (especially embodied aging studies) and post-colonial perspectives on aging, it explores how an emphasis on the body and embodiment can serve as a conceptual lens for understanding racialized aging bodies. A tentative framework for analysis is proposed. The concept of exile explores how bodies of color and older bodies are denigrated through the hegemonic (white, youth-centered, masculinist) gaze. Re-animation can take place by transcending double-consciousness: 'seeing beyond' the dominant gaze. Othering and otherness are explored in relation to both raced and aging bodies. The limits of ethnic aging are scrutinized at an epistemic level, simultaneously informing, and obscuring the understanding of lived experiences of racialized ethnic minorities in old age. Visible and invisible difference provide a way of unpacking the simultaneous hypervisibility of older (female) bodies of color, and their invisibility in institutional and policy discourses. De-coloniality is considered, by exploring ways to resist hegemonic power through embodied ways of knowing. This article concludes by exploring how recent methodological innovations - especially the visual and sensory turn - can offer new ways of understanding the lived experiences of aging bodies of color.

Is social engagement linked to body image and depression among aging women?

PubMed

Sabik, Natalie J

2017-01-01

Maintaining an active and engaged social life is a critical component of aging well, and women are generally more socially active than men. However, as women age their self-perceptions of their bodies may reduce social behaviors and consequently, increase depressive symptoms. Because little is known about how body image is associated with social engagement and depressive symptoms among aging women, four aspects of body image: satisfaction with cosmetic features, body function, physical appearance, and weight were assessed among women aged 65 and older (n = 123). Regression analyses indicated that cosmetic appearance, body function, and physical appearance were associated with depressive symptoms, whereas satisfaction with weight was unrelated. Further, both greater satisfaction with cosmetic features and body function were associated with higher levels of social engagement, and social engagement mediated the association between these aspects of body satisfaction and depressive symptoms. The findings indicate that specific age-relevant aspects of body satisfaction are linked to social behavior and depression among aging women, and reduced body satisfaction may lead to lower social engagement, and consequently aging women's health and well-being may be diminished.

There is an inverse association between educational level and body composition; however this association has strongly focused in young and adults population. The aim of this study was to analyze the educational levels attained in overweight and obesity Spanish elderly and to investigate if there was a correlation between having a low educational level and the risk of having overweight, central obesity or excess fat mass during the aging process. A representative sample of 2706 elderly (629 men and 2077 women; mean age of 72.1 ± 5.3 years) from Spain were assessed in the elderly EXERNET multi-center study between 2008 and 2009. Body composition was assessed in all subjects by bioelectrical impedance. ANCOVA was used to compare the averages between the groups. Logistic regression was used to calculate the association between educational level and the risk of having overweight, central fat or obesity. We observed significances between waist circumference and educational level in both sex (men 96.6 cm, women 86.3 cm); (p less than 0.05 and p less than 0.01, respective). There is an inverse association between the academic level, fat mass (29.5 kg) and percentage of body fat (40.8%) in women (p less than 0.05, p less than 0.01, respectively). No differences were observed in men. low educational level increases the possibility of having overweight or obesity in women and to have an increased waist circumference in both sexes.

Significant changes in body composition are known to occur with aging. The aim of the present study was to provide a normative reference of body composition and to investigate age and sex-related differences in healthy subjects by multifrequency bioelectrical impedance analyzer (BIA).A cross-sectional study was conducted on a sample of 3451 healthy Chinese adults, 1611 males and 1840 females. The volunteers were enrolled in 5 different age bands (18-30, 31-40, 41-50, 51-60, 60+). All subjects were measured for weight and height and submitted to BIA, to determine body composition. Body composition measures accounted for differences between men and women.A decrease in fat-free mass and increase in percent body fat was observed with aging, although the phenomenon was proved to be attenuated in women. The central and visceral redistribution of fat mass was also shown along lifetime.This study is a report on body composition of healthy subjects, to be used as an important data for future investigations and differences between nationalities and countries.

This study examined the impact of two interventions on body image, eating disorder risk and excessive exercise among 170 (65% female) trainee health education and physical education (HE&PE) teachers of mean (standard deviation) age 21.6 (2.3) who were considered an 'at-risk' population for poor body image and eating disorders. In the first year of the study, the control group cohort (n = 49 females, 20 males) received the regular didactic health education curriculum; in the second year of the study, the Intervention 1 cohort (n = 31 females, 21 males) received a self-esteem and media literacy health education program and in the third year of the study, the Intervention 2 cohort (n = 30 females, 19 males) received a combined self-esteem, media literacy and dissonance program using online and computer-based activities. Intervention 2 produced the best results, with males improving significantly in self-esteem, body image and drive for muscularity. Intervention 2 females improved significantly on Eating Disorders Inventory Drive for Thinness, Eating Disorder Examination and excessive exercise. The improvements were consistent at 6-month follow-up for females. It is feasible to promote body image, reduce body dissatisfaction and reduce excessive exercise among trainee HE&PE teachers via a health education curriculum.

Rare reports can be found about sex- and age-specific body composition survey among Chinese population. The aim of this study is to explore the change of sex-specific body compositions with aging among Chinese adolescents, adults and elders. In a large-scale population survey about physiological constants and health conditions, 75,714 subjects who aged from 8 to 80 completed body composition array. Body mass index (BMI), percentage body fat (PBF), water percentage of body weight (WPBW), water percentage of lean body mass (WPLBM), fat-free mass index (FFMI) and basic metabolic rate were examined with Biodynamics BI-310 body composition analyzer. General obesity is defined as BMI equal to or greater than 28 kg/m2. The prevalence rates of general obesity were 9.4% for males and 7.7% for females respectively. With aging, PBF and FMI showed a U-shape curvilinear trend and WPBW showed a parabolic trend for males. At same age group: 18-19 age groups, PBF and FMI declined to the valley and WPBW rose to the peak. For females, PBF, WPBW and FMI changed in a linear trend. The values of WPLBM and FFMI showed same curvilinear trend for two genders. WPLBM changed in a U-shape trend and touched the valley in twenties for males and in 18-19 age groups for females. The value of FFMI was larger for older age groups in the younger generation but smaller in the older generation. A parabolic trend peaking was seen in the thirties for males and in the forties for females. Regression models with age as independent variable showed that the larger rate of increase of PBF and smaller rates of increase for WPBM and WPLBM with aging for males. This study presents detailed data about sex-specific body composition conditions. Different change trend with aging was found about body composition conditions.

Body-mass dependence of age-related deterioration in human muscular function.

PubMed

Meltzer, D E

1996-04-01

Maximal anaerobic power of human muscles declines with increasing chronological age and is correlated with body mass. This study investigated whether the rate of deterioration in human muscular function among trained weight lifters is also correlated with body mass. Cross-sectional analysis of performance data of over 1,100 Masters competitors in Olympic-style weight lifting was carried out; eight body-weight classes and six age groups were represented. Two-lift total data (sum of snatch and clean and jerk lifts) were analyzed. Mean deterioration rates in the performance of athletes of widely diverse body masses were compared over the following age ranges: 42-57, 42-62, and 42-67 yr. No statistically significant correlation (P < 0.05) was found between rate of performance decline and body mass. The relationship between body mass and the magnitude of age-related variation of deterioration rate was also studied; no significant correlation was found. Previous studies have demonstrated that performance in Olympic-style weight lifting is correlated with maximal anaerobic muscular power. This leads us to suggest that the age-related deterioration rate of anaerobic power in trained subjects may not be correlated with the body mass of the individual.

Expanding the agenda for research on the physically active aging body.

PubMed

Phoenix, Cassandra; Grant, Bevan

2009-07-01

In this article, the authors consider the different approaches that can be used to examine the relationship between physical activity and aging. They propose that much is to be gained in our awareness of this dynamic relationship by drawing on multiple forms of knowledge that can generate diverse understandings regarding the impact of physical activity on physiological, psychological, and social aspects of aging. Accordingly, 3 different approaches to understanding the older physically (in)active body are presented. These are categorized as (a) the objective truth about the aging, physically active body; (b) the subjective truth about the aging, physically active body; and (c) "tales" about the aging, physically active body. The key underpinnings, strengths, and weaknesses of each approach are outlined. A number of examples from the literature are also offered to demonstrate where and how each approach has been used to contribute to our understanding about older people and physical activity. The more thorough, multidisciplinary, and wide spanning our knowledge of the aging, active body is, the more informed we might become in every dimension of its existence.

Changes in the body posture of women occurring with age

PubMed Central

2013-01-01

Background A current topic in the field of geriatrics still needing a great deal of study is the changes in body posture occurring with age. Symptoms of these changes can be observed starting between the ages of 40–50 years with a slow progression that increases after 60 years of age. The aims of this study were to evaluate parameters characterizing the posture of women over the age of 60 years compared with a control group and to determine the dynamics of body posture changes in the following decades. Methods The study included 260 randomly selected women. The study group consisted of 130 women between the ages of 60–90 years (Older Women). The control group (Younger Women) consisted of 130 women between the ages of 20–25 years (posture stabilization period). The photogrammetric method was used to evaluate body posture using the phenomenon of the projection chamber. The study was conducted according to generally accepted principles. Results In the analysis of parameters characterizing individual slope curves, results were varied among different age groups. The lumbar spine slope did not show significant differences between different age groups (p = 0.6952), while statistically significant differences (p = 0.0000) were found in the thoracic-lumbar spine slope (p = 0.0033) and upper thoracic spine slope. Body angle was shown to increase with age (p = 0.0000). Thoracic kyphosis depth significantly deepened with age (p = 0.0002), however, the thoracic kyphosis angle decreased with age (p = 0.0000). An increase in asymmetries was noticed, provided by a significantly higher angle of the shoulder line (p = 0.0199) and the difference in height of the lower shoulder blade angle (p = 0.0007) measurements in the group of older women. Conclusions Changes in the parameters describing body posture throughout consecutive decades were observed. Therapy for women over the age of 60 years should involve strengthening of the erector spinae

Prevalence of body image dissatisfaction and associated factors among physical education students.

To determine the prevalence of and factors associated with body image dissatisfaction among physical education students enrolled in a public university. This study evaluated 236 students and assessed body image perception (silhouette scale), sociodemographic variables (sex, age, parental education, marital status, university course, work, living arrangement, study shift, and income), physical activity level (International Physical Activity Questionnaire - Short Version), dietary habits, tobacco use, excessive intake of alcohol (questions from the tobacco, alcohol and drugs, and nutrition domains of the FANTASTIC instrument), and nutritional status (body mass index [BMI]). Descriptive analysis, the chi-square test, Fisher's exact test, and crude and adjusted multinomial regression were used. The prevalence of body image dissatisfaction was 69.5%; 44.1% were dissatisfied with excess weight. BMI ≥ 25.0 kg/m² was associated with dissatisfaction with excess weight; factors associated with dissatisfaction with slimness were being male, eating an unhealthy diet, and smoking tobacco. Our findings suggest that female college students with a BMI ≥ 25.0 kg/m² are more likely to present dissatisfaction with excess weight. Being male, eating an unhealthy diet, engaging in physical activity for < 739.61 min/week and smoking tobacco were the variables associated with dissatisfaction with thinness.

Strength training and body composition in middle-age women.

Strength training is a sound method to improve body composition. However, the effect of age, diet, menopause, and physical activity on the relationship between strength training and body composition in women remains unknown. The purpose of this study was to examine the intricacies of the relationship between strength training and body composition in 257 middle-age women and to quantify the effect of these factors on the association. The study was cross-sectional. Five variables were used to index strength training participation. Body composition was assessed by dual-energy X-ray absorptiometry. Diet was assessed by 7-day weighed food records, and physical activity was measured objectively using accelerometers. There were 109 strength trainers in the sample. For each day per week of strength training, body fat was 1.3 percentage points lower (F=14.8, P<0.001) and fat-free mass was 656 g higher (F=18.9, P<0.001). Likewise, the more time women spent lifting and the more intensely they trained, the better their body composition tended to be. Differences in age, energy and protein consumption had little effect on the associations. However, adjusting for differences in physical activity, and to a lesser extent, menopause status, weakened the relationships significantly. The more days, time, and effort women devote to strength training, the lower their body fat and the higher their fat-free mass tend to be. A significant portion of the differences in body composition seems to result from lifters participating in more physical activity than non-lifters. Menopause status also contributes significantly to the relationship.

2014-09-29

This study aimed to analyze the effects of age, family income, body mass index and dance practice on levels of body dissatisfaction and self-esteem in female students. The sample consisted of 283 female subjects attending a public school with a mean age of 11.51±1.60 years and a mean body mass index of 18.72 kg/m2 (SD=3.32). The instruments used were the Body Dissatisfaction Scale for Adolescents and the Rosenberg Self-Esteem Scale, both of which showed good internal consistency (0.77 and 0.81, respectively). The tests were applied (two-factor ANOVA) to compare the students practicing and those not practicing dance; the differences in the levels of body dissatisfaction (p=0.104) and self-esteem (p=0.09) were considered significant. The results demonstrated that age negatively correlated with body dissatisfaction (r=-0.19; p<0.01) and that higher body mass index levels were associated with greater body dissatisfaction (r=0.15, p=0.016) and lower levels of self-esteem (r=-0.17, p<0.01) only in non-practitioners. The practice of dance had a significant effect on levels of body dissatisfaction (F=4.79; p=0.030; η(2)=0.02), but there was no significant difference in self-esteem (F=1.88; p=0.172; η(2)=0.02). It can be concluded that female children and adolescents practicing dance have higher self-esteem, and are more satisfied with their body weight and their appearance. Moreover, results showed that self-esteem and body dissatisfaction were influenced by the body mass index levels only in the non-practitioners group.

We previously reported that higher education protects against executive dysfunction related to higher body mass index (BMI) in younger, but not older, adults. We now extend the previous analyses to verbal and nonverbal memory. Fifty-nine healthy, dementia-free community-dwelling adults ranging in age from 18 to 81 years completed the Hopkins Verbal Learning Test - Revised (HVLT-R) and the Brief Visuospatial Memory Test - Revised (BVMT-R). Self-reported years of education served as a proxy for cognitive reserve. We found that more highly educated individuals maintained their BVMT-R immediate recall performance across the range of BMI, but in less educated individuals, higher BMI was associated with worse performance. Our findings suggest that education may play a protective role against BMI-related nonverbal learning deficits, similar to previous reports for verbal memory and executive functioning. Results highlight the importance of considering educational background when determining the risk for BMI-related cognitive impairment in clinical settings.

We explored how physically active women perceived, experienced, and coped with their aging bodies, and examined their perceptions of the utility of self-compassion to manage aging body-related changes. Findings from a thematic analysis of interviews with 21 women aged 65-94 revealed that they were appreciative of how their bodies worked and accepting of their physical limitations, yet concurrently critical of their body's functionality and appearance. Participants engaged in physical activity and healthy eating to maintain their health and body functionality, yet also used diet, hair styling, anti-aging creams, makeup, physical activity, and clothing to manage their appearances. To assess their bodies (in)adequacies, they engaged in upward or downward social comparisons with others their age. Participants perceived self-compassion for the aging body to be idealistic and contextual. Findings highlight the importance of health and body functionality in influencing the cognitive, emotional, and behavioral management of the aging body. Copyright © 2017 Elsevier Ltd.

A higher prevalence of obesity in lower socioeconomic classes is common in Western societies. This study examined the role of gene-environment interactions in the association between parental education and body mass index (BMI) from infancy to the onset of adulthood. Parentally reported BMI from 1 to 13 and self-reported BMI from 14 to 20 years of age were collected in 16,646 complete Dutch twin pairs and analyzed by genetic twin modeling. At 7 to 8 years of age, children whose parents had middle or low educational levels had more excess weight than the children of more highly educated parents, and the difference increased until 18 to 20 years of age. The major part of the BMI variation was explained by additive genetic factors (a(2)  = 0.55-0.85), but environmental factors common for co-twins also played a significant role, especially from 3 to 7-8 years of age (c(2)  = 0.15-0.29). The genetic variation in BMI was higher in children whose parents had middle or low educational levels compared with children whose parents had a high educational level. The interaction between genetic factors and the childhood social environment may contribute to the formation of socioeconomic differences in obesity. © 2016 The Obesity Society.

Higher body weight is a well-known determinant of the metabolic syndrome (MetS) and its components. It is however less well studied how the change in weight from age 20 years to middle age or old age affects MetS development. In the community-based EpiHealth (n = 19,000, age range 45 to 75 years, 56% females) and PIVUS (n = 1000, all aged 70 years, 50% females) studies, the participants were asked about their body weight at age 20 years. Data were collected to determine MetS prevalence (NCEP ATP III criteria). In EpiHealth, the probability of having MetS increased fairly linearly with increasing weight from age 20 in the obese [odds ratios (OR) 1.04 per kg change in weight, 95% confidence interval (CI) 1.03-1.05, P < 0.0001], as well as in the overweight (OR 1.15, 95% CI 1.14-1.17, P < 0.0001) and normal-weight (OR 1.18, 95% CI 1.14-1.21, P < 0.0001), subjects after adjustment for age, sex, body mass index (BMI) at age 20, alcohol intake, smoking, education, and exercise habits. Also in the PIVUS study, the change in weight over 50 years was related to prevalent MetS (OR 1.08 per kg change in weight, 95% CI 1.06-1.10, P < 0.0001). In both studies, self-reported BMI at age 20 was related to prevalent MetS. Self-reported weight gain from age 20 was strongly and independently associated with prevalent MetS both in middle age or old age. Interestingly, this relationship was not restricted only to obese subjects. Our data provide additional support for the importance of maintaining a stable weight throughout life.

Mean stature and body mass at selected ages are useful indices of the health and well-being of children in a community. However, such data is not available in school children in Makurdi, Nigeria. The aim of this paper was to present the stature and body mass of children aged 9-12 years in Makurdi, Nigeria, with a view to providing baseline data for these physical characteristics. Anthropometric measurements of stature and body mass were taken in cross-sectional study of 2015 children (979 boys and 1036 girls) randomly selected from 19 public primary schools in Makurdi, Nigeria. The girls (Mean stature=138.9; SD=8.1 cm and body mass: 31.5; SD=6.1 kg) were significantly taller and heavier (P≤0.05) than the boys (Mean stature=137.2; SD=7.7 cm and body mass: 29.8; SD=4.4 kg). At all age categories the girls were taller than the boys. Except at age nine, the girls were significantly heavier than the boys at ages 10 to 12 years (p≤ 0.001). Stature and body mass increased with age in both boys and girls. In comparison with the NCHS growth reference, the Nigerian children were significantly shorter and lighter at all the ages than their American peers. Lower values of stature and body mass recorded in this sample in comparison with the NCHS standard are probably due to poor living conditions. Periodic monitoring of these anthropometric indicators in the children could provide reliable data for screening those with growth abnormalities so that appropriate health intervention strategies can be instituted.

Patients' beliefs about their condition have been shown to play a significant role in their pain experience and response to treatment, especially when a patient sees their tissue health as vulnerable or aged. Educational can alter these beliefs. Prior to new information, patients often have to be de-educated regarding common misbeliefs to undergo re-education. To determine if a brief de-education session regarding aging and low back pain (LBP) can shift pain ratings, fear-avoidance beliefs, beliefs regarding aging and LBP, and limited active trunk flexion. Fifty adults ranging from 50 to 93 years of age (SD = 10.73) with a 15.1 years of LBP were education on the poor correlation between aging and LBP. Prior to and immediately after the education pain ratings for LBP and leg pain (numeric pain rating scale-NPRS), fear-avoidance (fear avoidance beliefs questionnaire-FABQ), beliefs regarding aging and LBP (Likert scale) and active trunk flexion were measured. Significant changes were found in positive shifts with LBP (p = 0.002), leg pain (p = 0.042), FABQ-physical activity subscale (p = 0.004) and active trunk forward flexion (p < 0.001). The results show that education aimed at altering beliefs regarding LBP and aging result in a positive shift in pain, fear avoidance related to physical activity and active trunk flexion. Prior to providing patients with new healthcare information, de-educating them regarding poor beliefs may be helpful in shifting them towards new, healthier paradigms associated with their condition.

The stature/bi-iliac breadth method provides reasonably precise, skeletal frame size (SFS) based body mass (BM) estimations across adults as a whole. In this study, we examine the potential effects of age changes in anthropometric dimensions on the estimation accuracy of SFS-based body mass estimation. We use anthropometric data from the literature and our own skeletal data from two osteological collections to study effects of age on stature, bi-iliac breadth, body mass, and body composition, as they are major components behind body size and body size estimations. We focus on males, as relevant longitudinal data are based on male study samples. As a general rule, lean body mass (LBM) increases through adolescence and early adulthood until people are aged in their 30s or 40s, and starts to decline in the late 40s or early 50s. Fat mass (FM) tends to increase until the mid-50s and declines thereafter, but in more mobile traditional societies it may decline throughout adult life. Because BM is the sum of LBM and FM, it exhibits a curvilinear age-related pattern in all societies. Skeletal frame size is based on stature and bi-iliac breadth, and both of those dimensions are affected by age. Skeletal frame size based body mass estimation tends to increase throughout adult life in both skeletal and anthropometric samples because an age-related increase in bi-iliac breadth more than compensates for an age-related stature decline commencing in the 30s or 40s. Combined with the above-mentioned curvilinear BM change, this results in curvilinear estimation bias. However, for simulations involving low to moderate percent body fat, the stature/bi-iliac method works well in predicting body mass in younger and middle-aged adults. Such conditions are likely to have applied to most human paleontological and archaeological samples. Copyright © 2017 Elsevier Ltd. All rights reserved.

Less is known about longitudinal changes in quality of life between treatment completion and early survivorship among multimorbid cancer survivors. The current study describes longitudinal changes in quality of life among a multimorbid cohort of US Veterans diagnosed and treated for colorectal cancer. A sample of 68 multimorbid adults with colon and/or rectal cancer who received one or more treatment options (surgery, chemo or radiation therapy) was recruited. Participants were not excluded by cancer stage unless they reported being in hospice or similar status. Comprehensive assessments of quality of life and treatment side-effects were conducted 6, 12, and 18months after diagnosis. Descriptive statistics characterized treatment side-effects and changes in quality-of-life domains longitudinally. Multivariate Analysis of Variance identified sociodemographic and clinical variables associated with quality of life changes. Many physical symptoms improved from 6 to 18months following diagnosis, while some remained stable. Sexual symptoms worsened, attributable to increasing rates of dysfunction in older patients. Low education attainment was predictive of worse physical symptoms (F=5.59, p=.023) and associated with body concerns (F=5.7; p=.005) over time. Advanced cancer stage (F=4.94; p<.04) and receipt of chemotherapy (F=4.21; p<.05) independently predicted body concerns in multivariate analyses. Endorsement of physical and sexual symptoms and body concerns occurs in different patterns over time among multimorbid colorectal cancer survivors. Low education attainment is consistently associated with physical symptoms and body concerns. Cancer stage and chemotherapy are predictive of body concerns, but not physical or sexual symptoms.

Background Socioeconomic inequalities in birth weight and in body mass index (BMI) later in childhood are in opposite directions, which raises questions about when during childhood the change in direction happens. We examined how maternal and paternal education and household income were associated with birthweight z-scores and with BMI z-scores at age 5 and 12 months and 7 years, and we examined the socioeconomic differences in the tracking of these z-scores across infancy and childhood. Methods The associations were studied in a cohort of children in the Danish National Birth Cohort, single born between 1997 and 2003, for whom information on body size from at least 1 of 4 time points (n=85 062) was recorded. We examined the associations using linear mixed-effects modelling. Results Children from families with a low maternal and paternal educational level changed their body size z-scores upwards between birth and age 7 years. At age 5 and 12 months, there were no educational gradient. A low maternal educational level was associated with lower birth weight for gestational age z-scores at birth for boys (−0.199; 95% CI −0.230 to −0.169) and girls (−0.198; 95% CI −0.229 to −0.167) and higher BMI z-scores at age 7 for boys (0.198; 95% CI 0.154 to 0.242) and girls (0.218; 95% CI 0.173 to 0.264). There was not a similarly clear pattern in the tracking between different household income groups. However, a low household income level was associated with higher z-scores of both birth weight and BMI at age 7 years, but with a much weaker gradient at 5 and 12 months. Conclusions The educational gradient shifts from positive with birth weight, to none during infancy to inverse with BMI at age 7 years. In contrast, the income gradient was positive at birth and at 7 years and much weaker during infancy. PMID:28110282

Body Dissatisfaction and Self-Esteem in Female Students Aged 9–15: The Effects of Age, Family Income, Body Mass Index Levels and Dance Practice

2014-01-01

This study aimed to analyze the effects of age, family income, body mass index and dance practice on levels of body dissatisfaction and self-esteem in female students. The sample consisted of 283 female subjects attending a public school with a mean age of 11.51±1.60 years and a mean body mass index of 18.72 kg/m2 (SD=3.32). The instruments used were the Body Dissatisfaction Scale for Adolescents and the Rosenberg Self-Esteem Scale, both of which showed good internal consistency (0.77 and 0.81, respectively). The tests were applied (two-factor ANOVA) to compare the students practicing and those not practicing dance; the differences in the levels of body dissatisfaction (p=0.104) and self-esteem (p=0.09) were considered significant. The results demonstrated that age negatively correlated with body dissatisfaction (r=−0.19; p<0.01) and that higher body mass index levels were associated with greater body dissatisfaction (r=0.15, p=0.016) and lower levels of self-esteem (r=−0.17, p<0.01) only in non-practitioners. The practice of dance had a significant effect on levels of body dissatisfaction (F=4.79; p=0.030; η2=0.02), but there was no significant difference in self-esteem (F=1.88; p=0.172; η2=0.02). It can be concluded that female children and adolescents practicing dance have higher self-esteem, and are more satisfied with their body weight and their appearance. Moreover, results showed that self-esteem and body dissatisfaction were influenced by the body mass index levels only in the non-practitioners group. PMID:25713641

Cosmic-ray-exposure ages of meteorites provide information on the collisional history of their parent bodies and the delivery mechanism of meteorites to Earth. The exposure-age distributions of ordinary chondrites show distinct patterns for H, L, and LL types, consistent with their origin on different parent bodies. The exposure-age distributions of howardites, eucrites. and diogenites (HEDS) show a common pattern with major peaks at 22 Ma and 38 Ma This provides additional evidence for a common origin of the HED meteorites, possibly 4 Vesta, although orbital dynamics calculations showed that the delivery of meteorites from Vesta to Earth is difficult. However, the discovery of several kilometer-sized Vesta-like asteroids in the region between Vesta and the 3:1 resonance suggested that these seem more likely parent bodies of the HEDs than Vesta itself. This implies that the exposure-age clusters may represent samples of several parent bodies. Therefore, the near-absence of diogenites with ages <20 Ma might be of interest for the composition of these kilometer-sized fragments of Vesta. Here we present cosmic-ray-exposure ages of 20 diogenites, including 9 new meteorites. In addition, we calculate the probability for each peak to occur by chance, assuming a constant production rate of HED fragments.

Susceptibility and resilience to memory aging stereotypes: education matters more than age.

PubMed

Andreoletti, Carrie; Lachman, Margie E

2004-01-01

The authors examined whether the memory performance of young, middle-aged, and older adults would be influenced by stereotype versus counterstereotype information about age differences on a memory task. One hundred forty-nine adults from a probability sample were randomly assigned to a control group or to age-stereotype conditions. As predicted, counterstereotype information was related to higher recall compared to stereotype and control groups. This was true across all age groups, but only for those with more education. Both stereotype and counterstereotype information were related to lower recall compared to the control group across age groups for those with lower education. Results suggest those with more education are more resilient when faced with negative age stereotypes about memory and respond positively to counterstereotype information. In contrast, those with less education show greater susceptibility to the detrimental effects of age stereotypes and respond negatively to both stereotype and counterstereotype information about memory aging.

This report assesses the relationship of axial length of emmetropic (without refractive error) eyes to age, height, and weight in 1,600 Croatian schoolchildren. Axial eye lengths were determined by an ultrasonic eye biometry (A scan). Axial length of both eyes increases with age, height, and weight but shows a closer correlation to height and weight than to age. Boys have a significantly longer axial eye length than girls (P < 0.01). Boys or girls of similar or nearing body height and body weight and with emmetropic eyes have close linear measures of anatomic eye structures within their sex, regardless their age. Body height demonstrates the closest correlation to the growth and development of the emmetropic eye. Copyright 2005 Wiley-Liss, Inc.

The aim of this study was to define processes of orientation and/or selection towards sports game of volleyball in schoolgirls of Kastela, aged 10-12, by examining the relations between regular classes of physical education (PE) and extracurricular sport activities. For this purpose, two morphological measures were used (body height and body mass) and a set of 11 motor tests (6 basic motor abilities tests and 5 motor achievement tests) on a sample of 242 girls aged 10-12 was used, divided into a subsample of 42 girls participating in volleyball training (Volleyball players) and a subsample of 200 girls who do not participate in volleyball training (volleyball non-players). Based on the comparison of test results of schoolgirls from Kastela and Croatian norms, factor analysis of applied variables and discriminant analysis of these variables between volleyball players and non-players, processes and/or phases of selection in forming quality volleyball players were defined. Selection processes are preceded by orientation processes in physical education classes, i.e. choosing those sport activities which are in accordance with the biomotor status of students. Results have shown that orientation and initial selection in female volleyball needs to be executed based on the motor set of psychomotor speed, repetitive strength of the trunk and flexibility (muscle tone regulation), and body height. Volleyball training has affected the muscle mass development and the development of strength factors, so that explosive strength of jumping and/or takeoff along with body height, has predominantly differentiated female volleyball players from non-players, aged 10 to 12, and serve and spike quality will have dominant influence on the match outcome.

Large-scale systematic patterns of body size are a basic concern of evolutionary biology. Identifying body size variation along altitudinal gradients may help us to understand the evolution of life history of animals. In this study, we investigated altitudinal variation in body size, age and growth rate in Chinese endemic frog, Pelophylax pleuraden. Data sampled from five populations covering an altitudinal span of 1413 to 1935 m in Sichuan province revealed that body size from five populations did not co-vary with altitudes, not following Bergmann's rule. Average adult SVL differed significantly among populations in males, but not in females. For both sexes, average adult age differed significantly among populations. Post-metamorphic growth rate did not co-vary with altitude, and females grew faster than males in all populations. When controlling the effect of age, body size did not differ among populations in both sexes, suggesting that age did not affect variation in body size among populations. For females, there may be other factors, such as the allocation of energy between growth and reproduction, that eliminated the effect of age on body size. To our minds, the major reason of body size variation among populations in male frogs may be related to individual longevity. Our findings also suggest that factors other than age and growth rate may contribute to size differences among populations.

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 on the relationships between heart dimensions and growth or aerobic training in Arabian and Arabian-related endurance horses. Therefore the objective of the present study was to describe the influence of body dimensions (body length (BL), thoracic circumference (TC), withers height (WH)), BWT, age, gender, breed (purebred Arabians, part-bred Arabians, Anglo-Arabians, and Others) and the initiation of endurance training on echocardiographic measurements in competition-fit endurance horses aged 4 to 6 years. Most left atrial (LA) and left ventricular (LV) dimensions increased with age, whereas LA and LV 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 dimensions, breed and gender showed the most consistent influence on LA dimensions, whereas BWT, breed and kilometres covered in competition showed the most consistent influence on LV dimensions. The increase in echocardiographic dimensions with age indicates on-going growth in our population of 4 to 6 year-old horses. We also observed small changes associated with the initiation of endurance training. Morphometric dimensions had a greater influence on LA dimensions, whereas LV dimensions were also influenced (albeit weakly) by parameters associated with exercise intensity. These results may therefore reflect early adaptations linked to the initiation of endurance training.

To explore the relationship between early adulthood weight status and body weight changes from early adulthood to middle age and high-density lipoprotein cholesterol (HDL-C) level. Data were obtained from China Multicenter Collaborative Study of Cardiovascular Epidemiology Study, which was conducted in 1998, 15 participants population samples aged from 35-59 years old from 12 provinces were selected by random cluster sampling. Approximately 1 000 men and women in each sample population were surveyed for cardiovascular disease risk factors, body weight at age 25 from all participants were also obtained. Body mass index (BMI) at the age of 25 years was calculated with the weight at 25 years and the height measured during the survey, participants were divided into underweight (BMI<18.5 kg/m(2), n=1 331), normal-weight (18.5 kg/m(2)≤BMI <24 kg/m(2), n=10 400), overweight (24 kg/m(2)≤BMI<28 kg/m(2), n=2 019) and obesity (BMI≥28 kg/m(2), n=133) groups. Weight change was defined as the difference between the body weight at the age of 25 and at the survey and was grouped into<-7.5 kg (n=903), -7.5--2.6 kg (n=1 883), -2.5-2.5 kg (n=2 573), 2.6-7.5 kg (n=2 786), 7.6-12.5 kg (n=2 674) and>12.5 kg (n=3 064). The association of body weight status in early adulthood and body weight change from early adulthood to middle age with HDL-C level was examined by logistic regression model. The prevalence of low HDL-C in underweight, normal weight, overweight and obesity groups at age of 25 years were 10.7%(143/1 331), 15.5%(1 612/10 400), 16.3%(330/2 019) and 24.8%(33/133), respectively(P for trend <0.01). The prevalence of low HDL-C for adult weight change were 8.8%(79/903), 8.0%(151/1 883), 10.5%(269/2 573), 13.4%(373/2 786), 19.1%(511/2 674), and 24.0%(735/3 064)(P for trend <0.01)for weight change of <-7.5 kg, -7.5--2.6 kg, -2.5-2.5 kg, 2.6-7.5 kg, 7.6-12.5 kg and>12.5 kg, respectively.

Psammoma bodies are structures classified in the group of dystrophic calcifications, which occur in some kind of tumors and in choroid plexus during the aging process. Despite early discovery of their presence in choroid plexus stroma, mechanisms responsible for their formation remained unclear. Their presence in some kind of tumors was even more extensively studied, but significant breakthrough in the field of their etiology was not attained, too. However, till today correlation between their presence in tumors and aging is not established. Also, there are not any data about structural differences between ones found in tumors and ones found in choroid plexus. This might points to the assumption that besides the aging, some other causes might be involved in their formation in choroid plexus. Furthermore, it is contradictory that forms, like psammoma bodies, present in such malignant formations as tumors, represent quite benign phenomenon in choroid plexus. Literature data and the results of our previous researches revealed that there might be connections between, these, on the first sight quite different processes. Firstly, psammoma bodies are present in stroma of tumors with predominantly papillomatous morphology, which is present in choroid plexus, too. Initial forms of psammoma bodies might be formed in fibrovascular core of choroid plexus villi, similarly like in tumors papillae of papillary thyroid cancer. Their further growth leads to the progressive destruction of both tumors papillae and choroidal villi. Choroid plexus stroma is characterized by the fenestrated blood vessels presence, which are similar to newly formed vessels in tumors. This makes it vulnerable to the noxious agents from circulation. It can contain lymphocytes, macrophages, dendritic cells and myofibroblasts in cases with psammoma bodies, similarly to tumors stroma which is in activated, proinflammatory state. So, all these facts can suggest that similar processes can lead to psammoma

This study examined the effects of aging and education on participants' false memory for words that were not presented. Three age groups of participants with either a high or low education level were asked to study lists of semantically related words. Both age and education were found to affect veridical and false memory, as indicated in the recall and recognition of the studied word and nonstudied lures. A low education level had a negative effect on memory performance for both young and middle-aged adults. Older adults with a high level of education had a higher level of false memory than those with a lower education level. The results of this study are discussed in terms of the importance of education on false memory and mechanisms that create false memory of words in older adults.

Little is known about the extent to which aging trajectories of different body systems share common sources of variance. We here present a large twin study investigating the trajectories of change in five systems: cardiovascular, respiratory, skeletal, morphometric, and metabolic. Longitudinal clinical data were collected on 3,508 female twins in the TwinsUK registry (complete pairs:740 monozygotic (MZ), 986 dizygotic (DZ), mean age at entry 48.9 ± 10.4, range 18-75 years; mean follow-up 10.2 ± 2.8 years, range 4-17.8 years). Panel data on multiple age-related variables were used to estimate biological ages for each individual at each time point, in linear mixed effects models. A weighted average approach was used to combine variables within predefined body system groups. Aging trajectories for each system in each individual were then constructed using linear modeling. Multivariate structural equation modeling of these aging trajectories showed low genetic effects (heritability), ranging from 2% in metabolic aging to 22% in cardiovascular aging. However, we found a significant effect of shared environmental factors on the variations in aging trajectories in cardiovascular (54%), skeletal (34%), morphometric (53%), and metabolic systems (53%). The remainder was due to environmental factors unique to each individual plus error. Multivariate Cholesky decomposition showed that among aging trajectories for various body systems there were significant and substantial correlations between the unique environmental latent factors as well as shared environmental factors. However, there was no evidence for a single common factor for aging. This study, the first of its kind in aging, suggests that diverse organ systems share non-genetic sources of variance for aging trajectories. Confirmatory studies are needed using population-based twin cohorts and alternative methods of handling missing data.

Age-related effects of body mass on fertility and litter size in roe deer.

We analysed effects of females' body mass and age on reproductive capacity of European roe deer (Capreolus capreolus) in a large sample set of 1312 females (305 yearlings and 1007 adults), hunted throughout Slovenia, central Europe, in the period 2013-2015. Body mass positively affected probability of ovulation and potential litter size (number of corpora lutea), although its effect was more pronounced in yearlings than in adults. Between age groups, we found clear differences in responses of both reproductive parameters to body mass which influences primarily reproductive performance of younger, and in particular, lighter individuals: at the same body mass yearlings would at average have smaller litters than adults, and at lower body mass also young to middle-aged adults would have smaller litters than old ones. In addition, while yearlings have to reach a critical threshold body mass to attain reproductive maturity, adult females are fertile (produce ova) even at low body mass. However, at higher body mass also younger individuals shift their efforts into the reproduction, and after reaching an age-specific threshold the body mass does not have any further effects on the reproductive output of roe deer females. Increased reproductive capacity at more advanced age, combined with declining body mass suggests that old does allocate more of their resources in reproduction than in body condition.

Epidemiologic studies report conflicting results for the relationship between milk intake and adiposity in children. We examined prospective and cross-sectional associations between milk intake and percent body fat among 2245 children from the Avon Longitudinal Study of Parents and Children. Cross-sectional analyses were performed at age 13 y between total, full-fat, and reduced-fat milk intake assessed using 3-d dietary records and body fat from DXA. Prospective analyses were conducted between milk intakes at age 10 y and body fat at 11 and 13 y. Models were adjusted for age, sex, height, physical activity, pubertal status, maternal BMI, maternal education, and intakes of total fat, sugar-sweetened beverages, 100% fruit juice, and ready-to-eat cereals; baseline BMI was added to prospective models. Subset analyses were performed for those with plausible dietary intakes. Mean milk consumption at 10 and 13 y was (mean ± SD) 0.90 ± 0.73 and 0.85 ± 0.78 servings/d [1 serving = 8 oz of milk (244 g of plain and 250 g flavored milk)], respectively. Cross-sectional results indicated an inverse association between full-fat milk intake and body fat [β = −0.47 (95% CI = −0.76, −0.19); P = 0.001]. Milk intake at age 10 y was inversely associated with body fat at 11 y [β = −0.16 g/d (95%CI = −0.28, −0.04); P = 0.01], but not among those with plausible dietary intakes, suggesting that this association was influenced by dietary measurement errors. Milk intake was not associated with body fat at age 13 y after adjustment. Although our prospective results corroborate other findings of a null associations between milk intake and adiposity, our inconsistent findings across analyses suggest further investigation is needed to clarify the relation, and accounting for dietary reporting errors is an important consideration.

Body measurements and the variability of sitting postures at preschool age as preconditions for an optimal adjustment of chairs and tables.

PubMed

Voigt, Andrea; Greil, Holle

2009-03-01

Preschool age is a biological stage of intensive longitudinal growth with high plasticity of the growing body and of body postures. It is the period where children learn to persist in a sitting posture for a longer time and to use furniture like chairs or other body supporting systems. The growing body shows a special sensitivity for the manifestation of inappropriate postures. In this study the development of body measurements and sitting behaviour of preschool age children is investigated as a precondition for an optimal adjustment of seats and desks to the growing body. Accordingly to the instructions of Knussmann (1988) and Jiirgens (1988) 6 body measurements were taken from 122 German children aged 3 to 7 years from Potsdam, Province Brandenburg. Additionally, every child was videotaped for 10 minutes while crayoning in a sitting position of its own choice using a chair and a desk. To analyse the tapes, the software Noldus Observer was used and examined, picture by picture, to define the different types of sitting postures as well as the duration of persistence in a posture and the number of changes of postures. The used chairs and desks were also measured. Furthermore, the data of the furniture guideline DIN ISO 5970 (DIN, 1981), which regulates the dimensions of furniture for sitting in educational institutions, were compared with the results of the body measurements and with the dimensions of the furniture used by the children.

Young people who study physical education are a priori regarded as having proper body structure and body composition. This assumption cannot be confirmed in the subject literature. To determine the basic auxological parameters in youth who study physical education. 235 first-year students studying physical education were examined: 32% women (n=74) and 68% men (n=161). The students' body height, weight, waist, and hip circumference were measured. Body composition (bioimpedance method), specifying the body fat percentage (FM%) and fat free mass (FFM%) was also assessed. The mean normalized height of the female body was 0.48±1.07 SDS, and for the male body 0.51±1.04 SDS. The mean normalized weight for women was 0.4±0.94 SDS, and for men it was 0.83±0.9 SDS. The mean fat percentage in the body composition of women and men was, respectively, 21.5±5.06, ranging from 10.16% to 35.06%, and 12.5±3.97, ranging from 4.36% to 22.28%. In one-third of the women, the percentage of fat in the body composition was higher than 25%. 1. Young people who choose to study physical education and physical culture are characterized by greater height and greater body weight than the general population, regardless of gender. 2. Short persons study physical education less often than tall individuals. 3. The greater body weight observed in the majority of students studying physical education, in comparison to that of the general population, was caused by a dominant percentage of lean body mass in body composition; unexpectedly, however, some women were observed to have relatively high fat content. 4. Use of the body mass index and waist-hip ratio was not a sufficiently sensitive screening examination to detect fatness in physically active young adults; therefore, it should not substitute for the determination of fat content in body composition.

The longitudinal and transverse studies of girls aged 7 to 17 years living in Moscow and the town of Yelabuga were performed to monitor the dynamics of their growth processes, parameters of ectomorphism, mesomorphism and endomorphism depending on the type of body build. Anthropometric, anthroposcopic metods and cluster analysis were used to evaluate the type of body build according to V.G. Shtefko and A.G. Ostrovskiy (1928). Quantitative assessment of parameters of endo-, meso- and ectomorphism was performed using Heath-Carter method (1980). It was shown that the age-related variability of the types of body build appeared in association with the developmental heterochronism, which resulted from the uneven growth rate of different body components. The least variable parameters were found in the girls of digestive and asthenoid types of body build, while in girls of muscular and thoracic types these parameters changed more frequently. The critical periods during which the significant changes of somatotype were increased in number, were defined as 9 to 10 years and puberty period--11 to 14 years. Most sensitive time points in the time-course of somatotype establishment in girls are the ages of 12 and 14 years.

The purpose of this study was to examine the association between adolescents' body mass index (BMI) z-scores and their subsequent level of schooling, extending previous longitudinal research by using objectively measured weight and height data. A longitudinal study with 3 study waves (1-year intervals) involving 1248 Dutch adolescents (49% girls; mean age = 13.7 years) at schools providing different educational levels was used to determine adolescents who moved and did not move to a lower educational level in the first year, or in the second year, and to examine whether this movement could be predicted by BMI z-scores (zBMI), after controlling for a large range of potential confounding factors. A total of 1164 Dutch adolescents continued in the same level of education, whereas 84 adolescents moved to a lower educational level (43 moved in the first and 41 in the second year). A higher zBMI significantly increased the risk of a general transition to a lower educational level, and of a transition in the first year, but not in the second year, after controlling for potential demographic, behavioral, and psychological confounds. Findings suggest that a higher zBMI during adolescence immediately lowers educational achievement level during general secondary education. © 2014, American School Health Association.

Senescence is a highly variable process that comprises both age-dependent and state-dependent components and can be greatly affected by environmental conditions. However, few studies have quantified the magnitude of age-dependent and state-dependent senescence in key life-history traits across individuals inhabiting different spatially structured and seasonal environments. We used longitudinal data from wild female yellow-bellied marmots ( Marmota flaviventer ), living in two adjacent environments that differ in elevation and associated phenology, to quantify how age and individual state, measured as "time to death," affect body mass senescence in different environments. Further, we quantified how patterns of senescence differed between two biologically distinct seasons, spring, and late summer. Body mass senescence had an age-dependent component, expressed as a decrease in mass in old age. Overall, estimated age-dependent senescence was greater in females living in the more favorable lower elevation environment, than in the harsher higher elevation environment, and greater in late summer than in spring. Body mass senescence also had a state-dependent component, captured by effects of time to death, but only in the more favorable lower elevation environment. In spring, body mass gradually decreased from 2 years before death, whereas in late summer, state-dependent effects were expressed as a terminal decrease in body mass in the last year of life. Contrary to expectations, we found that senescence was more likely to be observed under more favorable environmental conditions, rather than under harsher conditions. By further demonstrating that senescence patterns differ among seasons, our results imply that within-year temporal environmental variation must be considered alongside spatial environmental variation in order to characterize and understand the pattern and magnitude of senescence in wild populations.

Single-ventricle congenital heart disease (SVCHD) requires multiple palliative surgical procedures that leave visible surgical scars and physical deficits, which can alter body-image and self-esteem. This study aimed to compare sex and age differences in body-image, self-esteem, and body mass index (BMI) in adolescents and adults with SVCHD after surgical palliation with those of a healthy control group. Using a comparative, cross-sectional design, 54 adolescent and adult (26 male and 28 female) patients, age 15–50 years, with SVCHD were compared with 66 age-matched healthy controls. Body-image and self-esteem were measured using the Multidimensional Body-Self Relations Questionnaire–Appearance Scale and Rosenberg Self-Esteem Scale. Height and weight were collected from retrospective chart review, and BMI was calculated. Female adolescents and adult patients with SVCHD reported lower body image compared with males patients with SVCHD and healthy controls (p = 0.003). Specific areas of concern were face (p = 0.002), upper torso or chest (p = 0.002), and muscle tone (p = 0.001). Patients with SVCHD who were <21 years of age had lower body image compared with healthy controls (p = 0.006). Self-esteem was comparable for both patients with SVCHD and healthy peers. There were no sex differences in BMI; BMI was higher in subjects >21 years of age (p = 0.01). Despite the similarities observed in self-esteem between the two groups, female patients with SVCHD <21 years of age reported lower perceived body-image. Our findings support the need to recognize poor psychological adjustment related to low self-esteem in patients with SVCHD; female patients warrant increased scrutiny. Strategies to help patients with SVCHD cope with nonmodifiable aspects of body-image during the difficult adolescent–to–young adult years may potentially enhance self-esteem and decrease psychological distress.

Age-related differences in body weight loss in response to altered thyroidal status.

1990-01-01

To determine whether age-related differences in body weight loss in hyperthyroidism could be related to caloric intake, the body weight and food consumption of Fischer 344 male rats were monitored every other day for four weeks. Six-month-old (young) rats were compared to 16-month-old rats (intermediate age) and 25-month-old (aged) rats. Hypothyroidism was induced with 0.025% methimazole in the drinking water for four weeks. Hyperthyroidism was induced with triiodothyronine (T3) injections (15 micrograms/100 g body weight i.p.) for the last 10 days of observation. A group of young rats pair fed with aged rats was included as a control group. The body weight changes of aged rats were similar to hypothyroid young rats. An index of T3 catabolic effect was calculated based on the net weight loss and food intake. This index was not different in aged rats compared to young rats. The apparent hypersensitivity of aged rats to T3 as evidenced by excessive weight loss could totally be attributed to decreased caloric intake. It is concluded that aged rats compared to the young are not more sensitive to the overall catabolic effects of thyroid hormones.

Body image distortion/discrepancy leads to psychological stress, disordered eating and mental and physical disease. To begin to assess body image distortion/discrepancy, we compared perceived, desired and measured percentage body fat in male versus female and college-aged versus non-college aged individuals. In addition, we assessed the acute stress response to body composition measurement. Body fat percentage of 15 college aged ('College Students'; CS) (mean = 19 years) and 16 non-college aged ('Non-College Aged Students'; NCS) (mean = 39 years) males and females was assessed with the BodPod Body Composition Tracking System (Life Measurement Instruments, Concord, CA, USA). Participants indicated their perception of body fat and their desired body fat using a somatomorphic matrix. Salivary cortisol, heart rate and blood pressure were also measured. Data were analysed by analysis of variance and alpha was set at 0.05. Mean (SD) percentage body fat of males [15.2% (6.1%)] was significantly lower than that of females [28.4% (6.4%)] (P < 0.0001). Both CS and NCS females perceived their body fat to be lower (5%) than measured body fat and desired their body fat to be lower (12%) than measured (P < 0.05). CS and NCS male participants demonstrated the opposite result; both CS and NCS male populations perceived their body fat to be higher (5%) than measured body fat and desired their body fat to be higher (4%) than measured (P < 0.05). No differences between any groups were observed in heart rate, blood pressure or cortisol response to body fat measurement. Sex-related but not age-related differences in perceived, desired and measured percentage body fat were observed. © 2014 The British Dietetic Association Ltd.

Science education in a secular age

A college science education instructor tells his students he rejects evolution. What should we think? The scene unfolds in one of the largest urban centers in the world. If we are surprised, why? Expanding on Federica Raia's (2012) first-hand experience with this scenario, I broaden her discussion by considering the complexity of science education in a secular age. Enjoining Raia within the framework of Charles Taylor's A Secular Age, I task the science education community to consider the broad strokes of science, religious faith, and the complexity of modernity in its evolving, hybridized forms. Building upon anthropological approaches to science education research, I articulate a framework to more fully account for who, globally, is a Creationist, and what this means for our views of ethically responsive science education.

DNA methylation-based age prediction from various tissues and body fluids

Aging is a natural and gradual process in human life. It is influenced by heredity, environment, lifestyle, and disease. DNA methylation varies with age, and the ability to predict the age of donor using DNA from evidence materials at a crime scene is of considerable value in forensic investigations. Recently, many studies have reported age prediction models based on DNA methylation from various tissues and body fluids. Those models seem to be very promising because of their high prediction accuracies. In this review, the changes of age-associated DNA methylation and the age prediction models for various tissues and body fluids were examined, and then the applicability of the DNA methylation-based age prediction method to the forensic investigations was discussed. This will improve the understandings about DNA methylation markers and their potential to be used as biomarkers in the forensic field, as well as the clinical field. PMID:28946940

This study aimed to analyse the types and locations of ingested foreign bodies according to different age groups, from infants to the elderly. A retrospective chart review. Tertiary referral centre. A total of 4682 patients who ingested foreign bodies from January 2006 through February 2014. The frequencies of foreign bodies were investigated in each age group. The types of foreign bodies were categorised into fish bones, chicken bones, seafood, tablets, food, metal, batteries, glass, teeth, plastics and others. The anatomic locations of the objects were classified as the oral cavity, tongue base, tonsils, oropharynx, hypopharynx, oesophagus, stomach and colon. The types, locations and origins of the foreign bodies were analysed according to the age groups. The frequency of foreign body ingestion was high in patients up to 14 years of age, after which the risk of foreign body ingestion markedly decreased. Fish bones were the most commonly suspected foreign bodies in all of the age groups. However, non-food-type foreign bodies were more common in both the young and elderly groups. The tonsils were the most common anatomic site of foreign body impaction except in the group of patients older than 65 years. The stomach and oesophagus were also common locations of foreign bodies in the groups of patients younger than 10 years (10.5%) and older than 65 years (39.4%). The frequency of foreign body ingestion was highest in young children. However, we observed specific age-based characteristics that indicate specific precautions to take to avoid foreign body ingestion. © 2015 John Wiley & Sons Ltd.

Greater educational attainment is associated with better neurocognitive health in older adults and is thought to reflect a measure of cognitive reserve. In vivo neuroimaging tools have begun to identify the brain systems and networks potentially responsible for reserve. We examined the relationship between education, a commonly used proxy for cognitive reserve, and N-acetylaspartate (NAA) in neurologically healthy older adults (N=135; mean age=66 years). Using single voxel MR spectroscopy, we predicted that higher levels of education would moderate an age-related decline in NAA in the frontal cortex. After controlling for the variance associated with cardiorespiratory fitness, sex, annual income, and creatine levels, there were no significant main effects of education (B=0.016, P=0.787) or age (B=-0.058, P=0.204) on NAA levels. However, consistent with our predictions, there was a significant education X age interaction such that more years of education offset an age-related decline in NAA (B=0.025, P=0.031). When examining working memory via the backwards digit span task, longer span length was associated with greater education (P<0.01) and showed a trend with greater NAA concentrations (P<0.06); however, there was no age X education interaction on digit span performance nor a significant moderated mediation effect between age, education, and NAA on digit span performance. Taken together, these results suggest that higher levels of education may attenuate an age-related reduction in neuronal viability in the frontal cortex.

Popular music scenes and aging bodies.

PubMed

Bennett, Andy

2018-06-01

During the last two decades there has been increasing interest in the phenomenon of the aging popular music audience (Bennett & Hodkinson, 2012). Although the specter of the aging fan is by no means new, the notion of, for example, the aging rocker or the aging punk has attracted significant sociological attention, not least of all because of what this says about the shifting socio-cultural significance of rock and punk and similar genres - which at the time of their emergence were inextricably tied to youth and vociferously marketed as "youth musics". As such, initial interpretations of aging music fans tended to paint a somewhat negative picture, suggesting a sense in which such fans were cultural misfits (Ross, 1994). In more recent times, however, work informed by cultural aging perspectives has begun to consider how so-called "youth cultural" identities may in fact provide the basis of more stable and evolving identities over the life course (Bennett, 2013). Starting from this position, the purpose of this article is to critically examine how aging members of popular music scenes might be recast as a salient example of the more pluralistic fashion in which aging is anticipated, managed and articulated in contemporary social settings. The article then branches out to consider two ways that aging members of music scenes continue their scene involvement. The first focuses on evolving a series of discourses that legitimately position them as aging bodies in cultural spaces that also continue to be inhabited by significant numbers of people in their teens, twenties and thirties. The second sees aging fans taking advantage of new opportunities for consuming live music including winery concerts and dinner and show events. Copyright © 2018 Elsevier Inc. All rights reserved.

Age-related body mass and reproductive measurements of gray wolves in Minnesota

Mech, L.D.

2006-01-01

Based on 65 free-ranging gray wolves (Canis lupus) of known age and 25 of estimated age examined during summers of 1970-2004 in northeastern Minnesota, body mass of both males and females peaked at 5 or 6 years of age, with mean masses of 40.8 kg and 31.2 kg, respectively. Testis size varied as a function of age and month through at least 8 years of age, with length plus width ranging from 1.9 to 7.8 cm. Most females aged 4-9 years bred based on assessment of nipple sizes; those that had not bred had average lower body mass than those that had. This is the 1st report of such data from known-aged wolves.

Vlahou, Christina H; Cohen, Lindsey L; Woods, Amanda M; Lewis, Jeffrey D; Gold, Benjamin D

2008-12-01

The aim of the current study was to determine whether age and body satisfaction predict dietary adherence in adolescents with Inflammatory Bowel Disease (IBD), and whether older females are less adherent than younger males and females. Forty-four participants aged 10-21 with IBD were recruited. Participants provided informed consent and demographics. Body satisfaction was measured by a questionnaire and a task in which participants selected their current and ideal body image out of silhouettes depicting bodies ranging from underweight to obese. Adherence was measured by marking a 100 mm visual analog scale, the 1-week completion of a dietary log, and a questionnaire evaluating coping strategies used for overcoming obstacles to dietary adherence. Age was related to dietary adherence, with younger children being more likely to adhere. Participants more satisfied with their body reported better dietary adherence. Findings remained consistent across multiple measures of body satisfaction and adherence. Healthcare providers and parents should be informed of these findings in order to improve adherence.

Evaluate the interaction between maternal age and education level in neonatal mortality, as well as investigate the temporal evolution of neonatal mortality in each stratum formed by the combination of these two risk factors. A nonconcurrent cohort study, resulting from a probabilistic relationship between the Mortality Information System and the Live Birth Information System. To investigate the risk of neonatal death we performed a logistic regression, with an odds ratio estimate for the combined variable of maternal education and age, as well as the evaluation of additive and multiplicative interaction. The neonatal mortality rate time series, according to maternal education and age, was estimated by the Joinpoint Regression program. The neonatal mortality rate in the period was 8.09‰ and it was higher in newborns of mothers with low education levels: 12.7‰ (adolescent mothers) and 12.4‰ (mother 35 years old or older). Low level of education, without the age effect, increased the chance of neonatal death by 25% (OR = 1.25, 95%CI 1.14-1.36). The isolated effect of age on neonatal death was higher for adolescent mothers (OR = 1.39, 95%CI 1.33-1.46) than for mothers aged ≥ 35 years (OR = 1.16, 95%CI 1.09-1.23). In the time-trend analysis, no age group of women with low education levels presented a reduction in the neonatal mortality rate for the period, as opposed to women with intermediate or high levels of education, where the reduction was significant, around 4% annually. Two more vulnerable groups - adolescents with low levels of education and older women with low levels of education - were identified in relation to the risk of neonatal death and inequality in reducing the mortality rate.

Background Greater educational attainment is associated with better neurocognitive health in older adults and is thought to reflect a measure of cognitive reserve. In vivo neuroimaging tools have begun to identify the brain systems and networks potentially responsible for reserve. Methods We examined the relationship between education, a commonly used proxy for cognitive reserve, and N-acetylaspartate (NAA) in neurologically healthy older adults (N = 135; mean age = 66 years). Using single voxel MR spectroscopy, we predicted that higher levels of education would moderate an age-related decline in NAA in the frontal cortex. Results After controlling for the variance associated with cardiorespiratory fitness, sex, annual income, and creatine levels, there were no significant main effects of education (B = 0.016, P = 0.787) or age (B = −0.058, P = 0.204) on NAA levels. However, consistent with our predictions, there was a significant education X age interaction such that more years of education offset an age-related decline in NAA (B = 0.025, P = 0.031). When examining working memory via the backwards digit span task, longer span length was associated with greater education (P < 0.01) and showed a trend with greater NAA concentrations (P < 0.06); however, there was no age X education interaction on digit span performance nor a significant moderated mediation effect between age, education, and NAA on digit span performance. Conclusions Taken together, these results suggest that higher levels of education may attenuate an age-related reduction in neuronal viability in the frontal cortex. PMID:25798329

Being cool: how body temperature influences ageing and longevity.

PubMed

Keil, Gerald; Cummings, Elizabeth; de Magalhães, João Pedro

2015-08-01

Temperature is a basic and essential property of any physical system, including living systems. Even modest variations in temperature can have profound effects on organisms, and it has long been thought that as metabolism increases at higher temperatures so should rates of ageing. Here, we review the literature on how temperature affects longevity, ageing and life history traits. From poikilotherms to homeotherms, there is a clear trend for lower temperature being associated with longer lifespans both in wild populations and in laboratory conditions. Many life-extending manipulations in rodents, such as caloric restriction, also decrease core body temperature. Nonetheless, an inverse relationship between temperature and lifespan can be obscured or reversed, especially when the range of body temperatures is small as in homeotherms. An example is observed in humans: women appear to have a slightly higher body temperature and yet live longer than men. The mechanisms involved in the relationship between temperature and longevity also appear to be less direct than once thought with neuroendocrine processes possibly mediating complex physiological responses to temperature changes. Lastly, we discuss species differences in longevity in mammals and how this relates to body temperature and argue that the low temperature of the long-lived naked mole-rat possibly contributes to its exceptional longevity.

Thé, Dwight J; Ploutz-Snyder, Lori

2003-07-01

The purpose of this study was to examine previously collected performance scores from the 2000 World Masters Weightlifting Championships to 1). determine the extent to which age and body mass are related to and predictive of indirect estimates of absolute and relative muscular power, and 2). assess possible gender differences in these associations. Dependent variables were absolute load (ABS = heaviest snatch [kg] + heaviest clean and jerk [kg]) and relative load (REL = ABS [kg]/body mass [kg]), representing indirect estimates of absolute and relative muscular power, respectively. Predictor variables were age (yr) and body mass (kg). Linear regression and various diagnostic procedures were used to analyze the data. The linear model provided an adequate fit for the data because no departures from the usual assumptions of normally distributed variables and homoscedastic error variance were observed. All predictor variables were significantly (P < 0.05) predictive of the dependent variables, but the magnitude of associations (e.g., R(ABS|BM) = 0.18 among females vs R(ABS|BM) = 0.57 among males) and extent of predictive ability (e.g., R(adj)2 for regression of ABS on age and body mass was 0.18-0.58 among females vs 0.74-0.83 among males) were significantly (P < 0.05) higher among males versus females. The extent to which age and body mass explain differences in muscular power differs between female and male masters weightlifters, but the rate of decline (%.yr-1) in power with advancing age is similar and is in agreement with previous reports for world record holders, other masters athletes, and healthy, untrained individuals, suggesting the importance of the aging process itself over physical activity history.

Age-congruency and contact effects in body expression recognition from point-light displays (PLD)

2016-01-01

Recognition of older people’s body expressions is a crucial social skill. We here investigate how age, not just of the observer, but also of the observed individual, affects this skill. Age may influence the ability to recognize other people’s body expressions by changes in one’s own ability to perform certain action over the life-span (i.e., an own-age bias may occur, with best recognition for one’s own age). Whole body point light displays of children, young adults and older adults (>70 years) expressing six different emotions were presented to observers of the same three age-groups. Across two variations of the paradigm, no evidence for the predicted own-age bias (a cross-over interaction between one’s own age and the observed person’s age) was found. Instead, experience effects were found with children better recognizing older actors’ expressions of ‘active emotions,’ such as anger and happiness with greater exposure in daily life. Together, the findings suggest that age-related changes in one own’s mobility only influences body expression categorization in young children who interact frequently with older adults.

Human body odor consists of various kinds of odor components. Here, we have investigated the changes in body odor associated with aging. The body odor of subjects between the ages of 26 and 75 was analyzed by headspace gas chromatography/mass spectrometry. 2-Nonenal, an unsaturated aldehyde with an unpleasant greasy and grassy odor, was detected only in older subjects (40 y or older). Furthermore, analysis of skin surface lipids revealed that omega7 unsaturated fatty acids and lipid peroxides also increased with aging and that there were positive correlations between the amount of 2-nonenal in body odor and the amount of omega7 unsaturated fatty acids or lipid peroxides in skin surface lipids. 2-Nonenal was generated only when omega7 unsaturated fatty acids were degraded by degradation tests in which some main components of skin surface lipids were oxidatively decomposed using lipid peroxides as initiator of an oxidative chain reaction. The results indicate that 2-nonenal is generated by the oxidative degradation of omega7 unsaturated fatty acids, and suggest that 2-nonenal may be involved in the age-related change of body odor.

Abstract Preserving physical and cognitive function becomes an important issue as people age. A growing number of studies have found that the correlation between body mass index (BMI) and cognitive function changes in different age groups. It is obvious that higher educational status is linked to higher cognitive function in terms of numerous risk factors that influence cognitive function. This study aimed to investigate the interplay between obesity and cognitive function categorized by different educational status. This study included 5021 participants aged 20 to 59 years who completed 3 neurocognitive function tests, including a simple reaction time test (SRTT), a symbol digit substitution test (SDST), and a serial digit learning test (SDLT) as reported in the National Health and Nutrition Examination Survey (NHANES) III database. The associations between neurocognitive function and BMI were analyzed using multivariate linear regression while controlling for confounders. After adjusting for pertinent covariates in mode 3, the β coefficients in the female participants with more than 12 years of education (interpreted as change of 3 neurocognitive function tests for each increment in BMI) comparing obesity groups to those with normal BMI were 16.2 (P < 0.001 for SRTT), 0.14 (P < 0.05 for SDST), and 0.9 (P < 0.05 for SDLT). Male participants with more than 12 years of education and female participants with fewer than 12 years of education demonstrated increased impairment as their BMI increased. However, this association was not significant after adjustments. Obese individuals had worse neurocognitive function than those of normal weight or overweight, especially in women with a high educational level. PMID:26844489

The morphology of human hyoid bone in relation to sex, age and body proportions.

2013-06-01

Morphological aspects of the human hyoid bone are, like many other skeletal elements in human body, greatly affected by individual's sex, age and body proportions. Still, the known sex-dependent bimodality of a number of body size characteristics overshadows the true within-group patterns. Given the ambiguity of the causal effects of age, sex and body size upon hyoid morphology the present study puts the relationship between shape of human hyoid bone and body proportions (height and weight) under scrutiny of a morphological study. Using 211 hyoid bones and landmark-based methods of geometric morphometrics, it was shown that the size of hyoid bones correlated positively with measured body dimensions but showed no correlation if the individual's sex was controlled for. For shape variables, our results revealed that hyoid morphology is clearly related to body size as expressed in terms of the height and weight. Yet, the hyoid shape was shown to result primarily from the sex-related bimodal distribution of studied body size descriptors which, in the case of the height-dependent model, exhibited opposite trends for males and females. Apart from the global hyoid shape given by spatial arrangements of the greater horns, body size dependency was translated into size and position of the hyoid body. None of the body size characters had any impact on hyoid asymmetry. Ultimately, sexually dimorphic variation was revealed for age-dependent changes in both size and shape of hyoid bones as male hyoids tend to be more susceptible to modifications with age than female bones.

Bonafide, Christopher P.; Brady, Patrick W.

2015-01-01

BACKGROUND AND OBJECTIVES: Heart rate (HR) is frequently used by clinicians in the hospital to assess a patient’s severity of illness and make treatment decisions. We sought to develop percentiles that characterize the relationship of expected HR by age and body temperature in hospitalized children and to compare these percentiles with published references in both primary care and emergency department (ED) settings. METHODS: Vital sign data were extracted from electronic health records of inpatients <18 years of age at 2 large freestanding children’s hospitals from July 2011 to June 2012. We selected up to 10 HR-temperature measurement pairs from each admission. Measurements from 60% of patients were used to derive the percentile curves, with the remainder used for validation. We compared our upper percentiles with published references in primary care and ED settings. RESULTS: We used 60 863 observations to derive the percentiles. Overall, an increase in body temperature of 1°C was associated with an increase of ∼10 beats per minute in HR, although there were variations across age and temperature ranges. For infants and young children, our upper percentiles were lower than in primary care and ED settings. For school-age children, our upper percentiles were higher. CONCLUSIONS: We characterized expected HR by age and body temperature in hospitalized children. These percentiles differed from references in primary care and ED settings. Additional research is needed to evaluate the performance of these percentiles for the identification of children who would benefit from further evaluation or intervention for tachycardia.

We conducted a qualitative study of 1,849 women over age 50 to capture the thoughts, feelings, and attitudes that women at middle age have about their bodies and the experience of aging. Via an open-ended question online survey, four primary themes emerged: (a) the physical and psychological experience of aging; (b) the injustices, inequities, and challenges of aging; (c) the importance of self-care; and (d) a plea for recognition of the need to maintain a contributory role in society. Results highlight the complexities of women's psychological and physical aspects of aging and point toward important topics worthy of further study in this growing population.

An individual's social and marital function, interpersonal relationships, and quality of life may, sometimes be affected by negative body image. This study is aimed at determining the relationship between body image and sexual function in middle-aged women. In this cross-sectional study, 437 middle-aged women, who were referred to various public healthcare centers in Ahvaz, Iran during 2014-2015, were selected. The Female Sexual Function Index (FSFI) and Body Shape Questionnaire (BSQ) were used for data collection. Chi-square, one-way analysis of variance, Spearman's correlation test, and logistic regression analysis were performed for statistical analysis. Approximately 58% of the participants expressed satisfaction with their body image, 35% were mildly dissatisfied, and 7% were moderately dissatisfied with their body image. Body image had a significant negative relationship with sexual satisfaction and sexual function (p=0.005). Furthermore, there was a significant relationship between body image and sexual desire (p=0.022), pain (p=0.001), sexual arousal (p<0.0005), sexual orgasm (p=0.001), and sexual satisfaction (p<0.0005). As the results indicated, body image is an important aspect of sexual health. In this study, women with a positive body image had higher sexual function valuation, compared to women with a negative body image. Also, body shape satisfaction was a predictor of sexual function.

Body Acceleration as Indicator for Walking Economy in an Ageing Population.

Valenti, Giulio; Bonomi, Alberto G; Westerterp, Klaas R

2015-01-01

In adults, walking economy declines with increasing age and negatively influences walking speed. This study aims at detecting determinants of walking economy from body acceleration during walking in an ageing population. 35 healthy elderly (18 males, age 51 to 83 y, BMI 25.5±2.4 kg/m2) walked on a treadmill. Energy expenditure was measured with indirect calorimetry while body acceleration was sampled at 60Hz with a tri-axial accelerometer (GT3X+, ActiGraph), positioned on the lower back. Walking economy was measured as lowest energy needed to displace one kilogram of body mass for one meter while walking (WCostmin, J/m/kg). Gait features were extracted from the acceleration signal and included in a model to predict WCostmin. On average WCostmin was 2.43±0.42 J/m/kg and correlated significantly with gait rate (r2 = 0.21, p<0.01) and regularity along the frontal (anteroposterior) and lateral (mediolateral) axes (r2 = 0.16, p<0.05 and r2 = 0.12, p<0.05 respectively). Together, the three variables explained 46% of the inter-subject variance (p<0.001) with a standard error of estimate of 0.30 J/m/kg. WCostmin and regularity along the frontal and lateral axes were related to age (WCostmin: r2 = 0.44, p<0.001; regularity: r2 = 0.16, p<0.05 and r2 = 0.12, p<0.05 respectively frontal and lateral). The age associated decline in walking economy is induced by the adoption of an increased gait rate and by irregular body acceleration in the horizontal plane.

Sarcopenia and age-related changes in body composition and functional capacity.

Advancing adult age is associated with profound changes in body composition. One of the most prominent of these changes is sarcopenia, defined as the age-related loss in skeletal muscle mass, which results in decreased strength and aerobic capacity and thus functional capacity. Sarcopenia is also closely linked to age-related losses in bone mineral, basal metabolic rate and increased body fat content. Through physical exercise and training, especially resistance training, it may be possible to prevent sarcopenia and the remarkable array of associated abnormalities, such as type II diabetes, coronary artery disease, hypertension, osteoporosis and obesity. Using an exercise program of sufficient frequency, intensity and duration, it is quite possible to increase muscle strength and endurance at any age. There is no pharmacological intervention that holds a greater promise of improving health and promoting independence in the elderly than does exercise.

Abnormal eating behavior, unhealthy weight control methods, and eating disordered symptoms have risen among college students. The aim of this study was to examine disordered eating attitudes and their relationship with anthropometric and body composition indices in physical education students in Tabriz, the capital of East Azerbaijan province, Iran. This cross-sectional study was conducted on 210 physical education students, 105 males and 105 females aged 18 to 25, who were selected by systematic random sampling from physical education faculty of Tabriz University in Tabriz, Iran, in 2013. Eating attitude test (EAT-26) was used for the assessment of disordered eating attitudes. In addition, anthropometric and body composition indices were assessed. About 10% of the studied subject had disturbed eating attitudes; significantly more males (15.4%) reported an EAT-26 ≥ 20 (disordered eating attitudes) than females (4.8%) (P < 0.05). In males, the EAT-26 score was positively correlated with weist perimeter (WP) (r = 0.21, P < 0.05) and the waist-to-hip ratio (r = 0.26, P < 0.01). In females, the EAT-26 score was positively correlated with weight (r = 0.19, P < 0.05) and the WP (r = 0.28, P < 0.01). In females, weight (P < 0.05), body mass index (BMI) (P < 0.05), WP (P < 0.01), and waist-to-hip ratio (P < 0.05) were significantly different between disordered eating attitude and healthy subjects, while in males there was no significant difference between the two groups regarding the anthropometric and body composition indices. Abnormal eating attitude was notable among physical education students in Tabriz, Iran. It seems that some anthropometric indices such as BMI and central obesity indices were related to the increase of disordered eating attitude.

To assess the effectiveness of the Melbourne Infant Feeding, Activity and Nutrition Trial (InFANT) Program according to maternal education and age. A cluster-randomised controlled trial involving 542 mother/infant pairs from 62 existing first-time parent groups was conducted in 2008 in Melbourne, Australia. The intervention involved 6 × 2-hour dietitian-delivered sessions, DVD and written resources from infant age 4-15 months. Outcomes included infant diet (3 × 24 h diet recalls), physical activity (accelerometry), television viewing and body mass index. We tested for moderation by maternal education (with/without a University degree) and age (< 32 and ≥ 32 years). The trial was registered with the ISRCTN Register (identifier 81847050). Interaction effects with the treatment arm were observed for maternal education and age. The intervention effects on vegetable (positive effect) and sweet snack consumption (negative effect) were greater in children with higher educated mothers while intervention effects on water consumption (positive effect) were greater in infants with lower educated mothers. The intervention was also more effective in increasing both vegetable and water consumption in infants with mothers aged < 32 years. Child obesity prevention interventions may be differentially effective according to maternal education and age. Evidence of differential effects is important for informing more sensitively targeted/tailored approaches. © 2013.

Total body bone density of adults from National Health and Nutrition Examination Survey (NHANES) 1999-2004 differed as expected for some groups (men>women and blacks>whites) but not others (whites>Mexican Americans). Cross-sectional age patterns in bone mineral density (BMD) of older adults differed at skeletal sites that varied by degree of weight-bearing. Total body dual-energy X-ray absorptiometry (DXA) data offer the opportunity to compare bone density of demographic groups across the entire skeleton. The present study uses total body DXA data (Hologic QDR 4500A, Hologic, Bedford MA, USA) from the NHANES 1999-2004 to examine BMD of the total body and selected skeletal subregions in a wide age range of adult men and women from three race/ethnic groups. Total body, lumbar spine, pelvis, right leg, and left arm BMD and lean mass from 13,091 adults aged 20 years and older were used. The subregions were chosen to represent sites with different degrees of weight-bearing. Mean BMD varied in expected ways for some demographic characteristics (men>women and non-Hispanic blacks>non-Hispanic whites) but not others (non-Hispanic whites>Mexican Americans). Differences in age patterns in BMD also emerged for some characteristics (sex) but not others (race/ethnicity). Differences in cross-sectional age patterns in BMD and lean mass by degree of weight-bearing in older adults were observed for the pelvis, leg, and arm. This information may be useful for generating hypotheses about age, race, and sex differences in fracture risk in the population.

In 1983-1984, 4578 Perth primary and secondary schoolchildren were studied. The selected sample was broadly representative of the ethnic groups that make up the Perth population and of the different social ranks within that population. The age, sex, weight, height, country of birth of the child and the parents, and occupation of the father were recorded for each subject. Weight, height and body mass index (BMI) increased with age. Age and sex were the most important determinants of body size. However, children of lower social rank and those with a southern European background were over-represented among the overweight children (greater than the 90th centile for BMI), particularly in adolescence. Children with an Asian background who were 11 years of age and younger were over-represented among the underweight children (less than or equal to the 10th centile for BMI). Results from this study indicate a continuing, though small (1.5 cm to 1.6 cm), secular increase in height over the past 13 to 14 years.

The use and distribution of child pornography is an increasing problem. Forensic anthropologists are often asked to estimate a child's age from a photograph. Previous studies have attempted to estimate the age of children from photographs using ratios of the face. Here, we propose to include body measurement ratios into age estimates. A total of 1603 boys and 1833 girls aged 5-16 years were measured over a 10-year period. They are 'Cape Coloured' children from South Africa. Their age was regressed on ratios derived from anthropometric measurements of the head as well as the body. Multiple regression equations including four ratios for each sex (head height to shoulder and hip width, knee width, leg length and trunk length) have a standard error of 1.6-1.7 years. The error is of the same order as variation of differences between biological and chronological ages of the children. Thus, the error cannot be minimised any further as it is a direct reflection of a naturally occurring phenomenon.

With the attendant rise of the number of medical colleges in India over past few decades, the demand for cadavers used in medical education and research is growing. However, there is an insufficient supply of donated cadavers available for dissection. This study was undertaken to assess the general population's awareness of body donation programs and willingness to donate in the State of Maharashtra, India. The willingness of participants to donate was compared with age, gender, and education of the respondents. A total of 625 adult individuals from the State of Maharashtra participated in a survey composed of questions about age, sex, education, awareness of body donation programs, and willingness to donate. It was found that 90.9% of the medical colleges surveyed reported an inadequate supply of cadavers. Of the general population, 32.1% of respondents were aware of body donation, compared to 95.83% of health care professionals. However, only 19.5% of the general population and 44.9% of health care professionals were willing to donate their bodies for anatomical education. Younger age groups, males, graduates, and postgraduates were found more willing to donate their bodies. Organ donation was preferred over body donation. A lack of awareness about body donation was the main factor responsible for respondents' "no body donation" response in the general population, along with firm religious beliefs and customs, the fear that the donated body will not be treated with respect and dignity, and the unacceptability of the dissection of one's own body. To overcome the current shortage of donated cadavers, efforts should be undertaken to change the mindset of the wider Indian society toward body donation. The authors believe this is possible through awareness campaigns and that prospective donors' concerns should be addressed appropriately. Proper guidance and assistance regarding body donation should be easily available for potential donors. Copyright © 2012 American

Objective We examine the mediating role of body image dissatisfaction (BID) on the association between obesity and depression and the variation of this association as a function of years of education among a population-based sample of women aged 40–65 years. Methods A series of sample-weighted logistic regression models were used to estimate the associations between obesity, BID, and depression, stratified by educational attainment. Data were obtained from a structured telephone interview of 4543 female health plan enrollees, including self-reported height and weight, the Patient Health Questionnaire assessment of depression, and a single-item measure of BID. Results Among those with <16 years of education, in both the unadjusted and adjusted models, obesity and BID were significantly associated with depression. Similarly, among those with ≥16 years of education, obesity and BID were significantly associated with depression in the unadjusted models. However, in the adjusted model, only BID was associated with depression. A formal test for mediation suggests that the association between obesity and depression was mediated by BID regardless of level of education. Conclusions Our data suggest that BID-mediated the obesity-depression association. In addition, obesity and BID may be salient risk factors for depression among middle-aged women as a function of the level of education. PMID:21109045

Objective: To investigate how associations between education and brain structure in older age were affected by adjusting for IQ measured at age 11. Methods: We analyzed years of full-time education and measures from an MRI brain scan at age 73 in 617 community-dwelling adults born in 1936. In addition to average and vertex-wise cortical thickness, we measured total brain atrophy and white matter tract fractional anisotropy. Associations between brain structure and education were tested, covarying for sex and vascular health; a second model also covaried for age 11 IQ. Results: The significant relationship between education and average cortical thickness (β = 0.124, p = 0.004) was reduced by 23% when age 11 IQ was included (β = 0.096, p = 0.041). Initial associations between longer education and greater vertex-wise cortical thickness were significant in bilateral temporal, medial-frontal, parietal, sensory, and motor cortices. Accounting for childhood intelligence reduced the number of significant vertices by >90%; only bilateral anterior temporal associations remained. Neither education nor age 11 IQ was significantly associated with total brain atrophy or tract-averaged fractional anisotropy. Conclusions: The association between years of education and brain structure ≈60 years later was restricted to cortical thickness in this sample; however, the previously reported associations between longer education and a thicker cortex are likely to be overestimates in terms of both magnitude and distribution. This finding has implications for understanding, and possibly ameliorating, life-course brain health. PMID:27664981

We investigated the effects of age as well as the linked factors of education and bilingualism on confrontation naming in rural Kashmir by creating a culturally appropriate naming test with pictures of 60 objects. We recruited 48 cognitively normal participants whose ages ranged from 18 to 28 and from 60 to 85. Participants in our study were illiterate monolinguals (N = 18) and educated Kashmiri-Urdu bilinguals (N = 30). Hierarchical multiple regression revealed that younger adults performed better than older adults (P < 0.01) and the age effect was quadratic (age2). It also showed Age X Education and Age X L2 Speaking interactions predicted naming performance. The Age X Education interaction indicated that the advantages of greater education increased with advancing age. Since education is in the second language (L2) in our population, this finding is no doubt linked to the Age X L2 Speaking interaction. This suggests that L2 speaking proficiency contributed more to first language (L1) naming with advancing age. PMID:24825965

The relationship of physique and body composition to strength in a group of physical education students.

PubMed Central

Bale, P.

1980-01-01

Fifty-three specialist women physical education students were measured anthropometrically and from these measurements somatotype and body composition were estimated. Leg, back and grip strength dynamometers were used to measure strength indices. Arm strength was calculated from each subject's pull-ups and push-ups and lung capacity was measured using a spirometer. The somatotype ratings and percent fat measurements indicate that the P.E. students are generally more muscular and less fat for their age than non-P.E. students. There was a strong relationship between percent fat and the endomorphy rating and a moderate relationship between lean body weight and mesomorphy. The moderate relationship of the strength variables with the muscular rating, whether expressed as mesomorphy or lean body weight, suggests that the higher a subject's muscular component the greater their dynamic strength.

Shift work and age as interactive predictors of body mass index among offshore workers.

PubMed

Parkes, Katharine R

2002-02-01

This study investigated shift pattern (day shifts versus day-night rotation) and its interactions with age, and with years of shiftwork exposure, as predictors of body mass index (BMI). Survey data were collected from offshore personnel working day shifts (N=787) or day-night shifts (N=787); information was obtained about shift pattern and years of shiftwork exposure, height, weight, demographic factors, and smoking habits. Hierarchical multiple regression was used to test a model in which BMI was predicted by additive and interactive effects of shift pattern, age, and exposure years with control for confounding variables. In a multivariate analysis (controlling for job type, education and smoking), BMI was predicted by the main effects of age and years of shiftwork exposure. Shift pattern was not significant as a main effect, but it interacted significantly with the curvilinear age term and with the linear and curvilinear components of shiftwork exposure. In the day shift group, age but not exposure predicted BMI; the opposite was true of the day-night shift group. The increase in BMI with an increase in age and exposure years was steeper for the day-night shift group than for the day shift group. The significant interaction effects found in this study were consistent with the view that continued exposure to day-night shift work gives rise to increases in BMI, over and above the normative effects of ageing on BMI shown by day-shift workers.

Old, down and out? Appearance, body work and positive ageing among elderly South Korean women.

PubMed

Elfving-Hwang, Joanna

2016-08-01

This article offers an as yet unexplored dimension of our current understanding of the ageing body in the context of contemporary South Korea. Drawing on interviews with twenty elderly women living in the greater Seoul metropolitan area, this article explores the role of appearance, body work, and the presentation of self in the women's everyday lived experiences. Existing research on the ageing female body in South Korea has primarily focused on the so-called noin munjae ('the elderly issue') discourse, within which the ageing body is framed as passive, undesirable, or out-of-control. Contrary to this, the elderly women's own narratives of everyday beauty practices suggest that the act of sustaining well-ordered appearance in later life allows for the enforcing of positive selves in the context of personal beauty and body work. Maintaining a positive appearance was shown to play an important part of their everyday lives, and functioned as a ritual of not only presenting an appearance that signified control over the ageing body, but to continue to enjoy it. The carefully calculated engagement with various non-surgical and surgical beauty practices also emerged as an embodied practice of mediating intersubjective social encounters through which self-esteem was engendered by evidencing the self's efforts to show respect to others. The findings of this study challenge dominant discourses in the west which present body work on the ageing female body as primarily self-indulgent, or driven by anxiety about the body's inability to fit within existing youthful beauty ideals.

To examine associations of demographic, perinatal, and infant feeding characteristics with offspring body composition at approximately 5 months of age. We collected data on 640 mother/offspring pairs from early pregnancy through approximately 5 months of age. We assessed offspring body composition with air displacement plethysmography at birth and approximately 5 months of age. Linear regression analyses examined associations between predictors and fat-free mass, fat mass, and percent fat mass (adiposity) at approximately 5 months. Secondary models further adjusted for body composition at birth and rapid infant growth. Greater prepregnant body mass index and gestational weight gain were associated with greater fat-free mass at approximately 5 months of age, but not after adjustment for fat-free mass at birth. Greater gestational weight gain was also associated with greater fat mass at approximately 5 months of age, independent of fat mass at birth and rapid infant growth, although this did not translate into increased adiposity. Greater percent time of exclusive breastfeeding was associated with lower fat-free mass (-311 g; P < .001), greater fat mass (+224 g; P < .001), and greater adiposity (+3.51%; P < .001). Compared with offspring of non-Hispanic white mothers, offspring of Hispanic mothers had greater adiposity (+2.72%; P < .001) and offspring of non-Hispanic black mothers had lower adiposity (-1.93%; P < .001). Greater adiposity at birth predicted greater adiposity at approximately 5 months of age, independent of infant feeding and rapid infant growth. There are clear differences in infant body composition by demographic, perinatal, and infant feeding characteristics, although our data also show that increased adiposity at birth persists through approximately 5 months of age. Our findings warrant further research into implications of differences in infant body composition. Copyright © 2017 Elsevier Inc. All rights reserved.

To identify the sociodemographic characteristics and risk factors associated with suspected foreign bodies in the ear, nose, throat, airway, and esophagus among Polish children. Case series with chart review. Setting Tertiary care medical center. A retrospective analysis of the medical records of patients hospitalized for a suspected foreign body (FB) between 1998 and 2008 was conducted. Data regarding place of residence, presence of siblings, parents' educational status, seasonality, psychomotor development, age, and sex were collected and statistically analyzed. Of the 1011 patients with suspected foreign body insertion, 849 (84%) had a positive diagnosis. Of the confirmed foreign bodies, 96 were found in the tracheobronchial tree, 142 were found in the esophagus, and 611 were located in the external auditory canals, nasopharyngeal passage, tonsils, auricles, or lips. Sociodemographically, 596 of the children came from urban areas, with a preponderance of males (55%). Objects were removed more frequently in summer and autumn (60%). Children with siblings (53%) predominated. The majority of patients (52%) had parents with an elementary education. Food was the most frequent foreign body in children under 3 years of age. Patients with delayed psychomotor development constituted 1.6% of the analyzed population. Being male, 1 to 3 years of age, belonging to an urban family with siblings, and having parents with an elementary education increased the risk of foreign body insertion. Training caregivers about proper nutrition and safety rules when playing with children can reduce the risk of accidents related to foreign body insertion.

A total of 462 schoolgirls aged 7-8 and 17-18 years were examined anthropometrically (45 body measurements and 10 skinfolds) in a cross-sectional study. The data were processed in two age groups: 7-8-year-olds (n = 205) and 17-18-year-olds (n = 257). Relying on average height and weight in the groups, both groups were divided into five body build classes: small, medium, large, pyknomorphous and leptomorphous. In these classes, the differences in all other body measurements were compared, and in both age groups, analogous systematic differences were found in length, width and depth measurements and circumferences. This enabled us to compare proportional changes in body measurements during ten years, using for this ratios of averages of basic measurements and measurement groups in the same body build classes. Statistical analysis by the sign test revealed statistically significant differences between various body build classes in the growth of averages. Girls belonging to the small class differed from the girls of the large class by an essentially greater increase in their measurements. Our results suggest that the growth rate of body measurements of girls with different body build can be studied by the help of body build classification.

It is well known that the prevalence of overweight and obesity is considerably higher among youth from lower socio-economic families, but there is little information about the role of some energy balance-related behaviors in the association between socio-economic status and childhood overweight and obesity. The objective of this paper was to assess the possible mediation role of energy balance-related behaviors in the association between parental education and children's body composition. Data were obtained from the cross sectional study of the "EuropeaN Energy balance Research to prevent excessive weight Gain among Youth" (ENERGY) project. 2121 boys and 2516 girls aged 10 to 12 from Belgium, Greece, Hungary, the Netherlands, Norway, Slovenia and Spain were included in the analyses. Data were obtained via questionnaires assessing obesity related dietary, physical activity and sedentary behaviors and basic anthropometric objectively measured indicators (weight, height, waist circumference). The possible mediating effect of sugared drinks intake, breakfast consumption, active transportation to school, sports participation, TV viewing, computer use and sleep duration in the association between parental education and children's body composition was explored via MacKinnon's product-of-coefficients test in single and multiple mediation models. Two different body composition indicators were included in the models, namely Body Mass Index and waist circumference. The association between parental education and children's body composition was partially mediated by breakfast consumption, sports participation, TV viewing and computer use. Additionally, a suppression effect was found for sugared drinks intake. No mediation effect was found for active transportation and sleep duration. The significant mediators explained a higher proportion of the association between parental education and waist circumference compared to the association between parental education and BMI

Gestational age-dependent risk factors for preterm birth: associations with maternal education and age early in gestation.

Preterm birth (PTB) before 37 weeks can occur over a wide range of gestational ages, but few studies have assessed if associations between risk factors and PTB vary over the duration of gestation. We sought to evaluate if associations between two major risk factors (maternal education and age) and PTB depend on gestational age at delivery. We estimated hazard ratios of PTB for education and age in a time-to-event analysis using a retrospective cohort of 223,756 live singleton births from the province of Québec, Canada for the years 2001-2005. Differences in hazards of maternal education and age with PTB were assessed over gestational age in a Cox proportional hazards model using linear and nonlinear time interaction terms, adjusting for maternal characteristics. Associations of PTB with lower (vs. higher) education and older (vs. younger) age strengthened progressively at earlier gestational ages, such that the risk of PTB for maternal education and age was not constant over the course of gestation. Associations of PTB with risk factors such as maternal low education and older age may be stronger early in gestation. Models that capture the time-dependent nature of PTB may be useful when the goal is to assess associations at low gestational ages, and to avoid masked or biased associations early in gestation.

Socioeconomic gradients in body mass index (BMI) in US immigrants during the transition to adulthood: examining the roles of parental education and intergenerational educational mobility.

Albrecht, Sandra S; Gordon-Larsen, Penny

2014-09-01

Despite comparatively lower socioeconomic status (SES), immigrants tend to have lower body weight and weaker SES gradients relative to US-born individuals. Yet, it is unknown how changes in SES over the life-course relate to body weight in immigrants versus US-born individuals. We used longitudinal data from a nationally representative, diverse sample of 13 701 adolescents followed into adulthood to investigate whether associations between SES mobility categories (educational attainment reported by individuals as adults and by their parents during adolescence) and body mass index (BMI) measured in adulthood varied by immigrant generation. Weighted multivariable linear regression models were adjusted for age, sex, race/ethnicity and immigrant generation. Among first-generation immigrants, although parental education was not associated with adult BMI, an immigrant's own education attainment was inversely associated with BMI (β=-2.6 kg/m(2); SE=0.9, p<0.01). In addition, upward educational mobility was associated with lower adult mean BMI than remaining low SES (β=-2.5 kg/m(2); SE=1.2, p<0.05). In contrast, among US-born respondents, college education in adulthood did not attenuate the negative association between parental education and adult BMI. Although an SES gradient emerged in adulthood for immigrants, remaining low SES from adolescence to adulthood was not associated with loss of health advantage relative to US-born respondents of US-born parents of similar SES. Immigrants were able to translate higher SES in adulthood into a lower adult mean BMI regardless of childhood SES, whereas the consequences of lower childhood SES had a longer reach even among the upwardly mobile US born.

Whole-body vibration (WBV) is a well-known light-resistance exercise by automatic adaptations to rapid and repeated oscillations from a vibrating platform, which is also a simple and convenient exercise for older adults. However, the potential benefits of WBV on aging-associated changes in body composition, exercise performance, and fatigue are currently unclear. The objective of the study is to investigate the beneficial effects of WBV training on body composition, exercise performance, and physical fatigue-related and biochemical responses in middle-aged mice. In total, 24 male C57BL/6 mice aged 15 months old were randomly divided into 3 groups (n=8 per group): sedentary control (SC), relatively low-frequency WBV (5.6 Hz, 2 mm, 0.13 g) (LV), and relatively high-frequency WBV (13 Hz, 2 mm, 0.68 g) (HV). Mice in the LV and HV groups were placed inside a vibration platform and vibrated at different frequencies and fixed amplitude (2 mm) for 15 min, 5 days/week for 4 weeks. Exercise performance, core temperature and anti-fatigue function were evaluated by forelimb grip strength and levels of serum lactate, ammonia, glucose, and creatine kinase (CK) after a 15-min swimming exercise, as were changes in body composition and biochemical variables at the end of the experiment. Relative muscle and brown adipose tissue weight (%) was significantly higher for the HV than SC mice, but relative liver weight (%) was lower. On trend analysis, WBV increased grip strength, aerobic endurance and core temperature in mice. As well, serum lactate, ammonia and CK levels were dose-dependently decreased with vibration frequency after the swimming test. Fasting serum levels of albumin and total protein were increased and serum levels of alkaline phosphatase and creatinine decreased dose-dependently with vibration frequency. Moreover, WBV training improved the age-related abnormal morphology of skeletal muscle, liver and kidney tissues. Therefore, it could improve exercise performance and

The prevalence of obesity is highest in older persons and a correct self-perception of body weight status is necessary for optimal weight control. The aim of this study was to determine self-perception of, and satisfaction with, body weight status, and to compare current versus ideal body image in a large, nationally representative sample of older people. Furthermore, determinants of misperception were explored. A cross-sectional study. The Longitudinal Aging Study Amsterdam (LASA), conducted in a population-based sample in the Netherlands. 1295 men and women aged 60-96 years. Body weight status was assessed using measured weight and height. Self-perceived body weight status, satisfaction with body weight and current and ideal body image were also assessed. Multiple logistic regression analysis was used to investigate the association of age, educational level and objectively measured BMI with underestimation of body weight status. The prevalence of obesity was 19.9% in men and 29.3% in women. The agreement between objective and self-perceived body weight status was low (Kappa < 0.2). Among overweight and obese persons, 42.1% of men and 44.1% of women were (very) dissatisfied with their body weight status and >99% of obese participants desired to be thinner (ideal body image < current image). Only 4.4% of obese men and 12.3% of obese women perceived their body weight status correctly. Higher age (women), lower educational level (men) and higher BMI (all) were associated with greater underestimation of body weight status. Many older persons misperceive their body weight status. Future actions to improve body weight perception in older persons are necessary to increase the impact of public health campaigns focussing on a healthy body weight in old age.

Body composition and blood pressure in children based on age, race, and sex.

We evaluated 675 nine- and twelve-year-old children for body composition and circulatory differences based on age, race, and sex. The specific variables measured included height, weight, triceps and subscapula skinfolds, body mass index, percentage fat, fat-free weight, and systolic, diastolic, and mean arterial blood pressures. A 2 x 2 x 2 factorial multiple analysis of variance (MANOVA) test of significance showed body composition and blood pressure differences (P < .01) for race, age, and sex. The univariate test of the specific variables within the factors showed that black children had higher fat-free weights and lower fat levels but higher blood pressure values (P < .05) than white children. Boys had lower fat levels than girls, and the older children had higher values on the body composition variables but not on blood pressure. Zero order correlations between body composition and blood pressure ranged from 0.14 to 0.55; systolic blood pressure and body weight shared the highest correlation. These data show that, although black children have less body fat than white children, they are heavier and have higher blood pressure. We hypothesize that some aspect of fat-free body weight may contribute to hypertension in black individuals.

Effects of age on recovery of body weight following REM sleep deprivation of rats.

Chronically enforced rapid eye (paradoxical) movement sleep deprivation (REM-SD) of rats leads to a host of pathologies, of which hyperphagia and loss of body weight are among the most readily observed. In recent years, the etiology of many REM-SD-associated pathologies have been elucidated, but one unexplored area is whether age affects outcomes. In this study, male Sprague-Dawley rats at 2, 6, and 12 months of age were REM sleep-deprived with the platform (flowerpot) method for 10-12 days. Two-month-old rats resided on 7-cm platforms, while 10-cm platforms were used for 6- and 12-month-old rats; rats on 15-cm platforms served as tank controls (TCs). Daily changes in food consumption (g/kg(0.67)) and body weight (g) during baseline, REM-SD or TCs, and post-experiment recovery in home cages were determined. Compared to TCs, REM-SD resulted in higher food intake and decreases in body weight. When returned to home cages, food intake rapidly declined to baseline levels. Of primary interest was that rates of body weight gain during recovery differed between the age groups. Two-month-old rats rapidly restored body weight to pre-REM-SD mass within 5 days; 6-month-old rats were extrapolated by linear regression to have taken about 10 days, and for 12-month-old rats, the estimate was about 35 days. The observation that restoration of body weight following its loss during REM-SD may be age-dependent is in general agreement with the literature on aging effects on how mammals respond to stress.

The aim of the study was to identify the effect of overweight, obesity, and conditions related to body weight on quality of life and to assess the relationship between body weight and satisfaction with body image between middle-aged Lithuanian inhabitants of Kaunas city. MATERIAL AND METHODS. A random sample of 1403 Kaunas men and women, aged 35-64 years and stratified by age and sex, was examined in 2001-2002. Response rate was 62.4%. Examination included physical measurements and information on risk factors related to lifestyle. Quality of life was assessed by World Health Organization Quality of Life 100 questionnaire. Multivariate analyses were performed to identify the effect of excess body weight and conditions linked to body weight on quality of life. RESULTS. Less than three-fourths (73%) of men and women had excess body weight (body mass index, > or =25.0 kg/m(2)). Obesity in a complex with other analyzed factors had a negative effect on men's quality of life in the independence domain as compared to ones with BMI of <25.0 kg/m(2) (OR=1.87; 95% CI=1.08-3.26). Obesity for women increased the odds of having worse quality of life in the psychological and independence domains. Mean scores of body image and appearance facet for men with normal body mass were 73.5, for overweigh ones 72.2, and for obese 66.8 (for women 69.9, 63.3, and 52.9, respectively; P=0.0001). CONCLUSIONS. Among women excess body weight was associated with impaired quality of life. Men with excess body weight reported better overall quality of life. Obese persons were less satisfied with their body image as compared to ones with normal body weight.

Until the advent of plastinated cadavers, few outside the medical professions have had firsthand experience with human corpses. Such opportunities are now available at the Body Worlds exhibits of Gunther von Hagens. After an overview of these exhibits, we explore visitor responses as revealed in comment books available upon exiting the exhibit. Cultural, philosophical, and religious issues raised in the comments serve as a microcosm of society at large. The conclusion considers the challenge of such exhibits in introducing the public to science education, notes the image of the body as machine-so prevalent in the West-reflected in visitor comments, and finds hope that the exhibits promote, for many visitors, a sense of community among all humankind.

Little is known about the association of dissatisfaction with body weight - a component of body image - with depression in individuals of different sex, age, and with different body mass index (BMI). Hence, the aim of our study was to evaluate the association of body weight dissatisfaction (BWD) with depression in different sub-groups. We analyzed data of 15,975 individuals from the cross-sectional 2012 Swiss Health Survey. Participants were asked about their body weight satisfaction. The validated Patient Health Questionnaire (PHQ-9) was used to ascertain depression. Age was stratified into three groups (18-29, 30-59, and ≥60 years). The body mass index (BMI) was calculated from self-reported body height and weight and categorized into underweight (BMI <18.5 kg/m(2)), normal weight (BMI 18.5-24.9 kg/m(2)), overweight (BMI 25.0-29.9 kg/m(2)), and obesity (BMI ≥30 kg/m(2)). The association between body weight dissatisfaction (BWD) and depression was assessed with logistic regression analyses and odds ratios (OR) with 95 % confidence intervals (CI) were computed. BWD was associated with depression in the overall group (OR 2.04, 95 % CI 1.66-2.50) as well as in men (OR 1.85, 95 % CI 1.34-2.56) and women (OR 2.25, 95 % CI 1.71-2.96) independent of BMI. The stratification by age groups showed significant associations of BWD with depression in young (OR 1.78, 95 % CI 1.16-2.74), middle-aged (OR 2.10, 95 % CI 1.61-2.74) and old individuals (OR 2.34, 95 % CI 1.30-4.23) independent of BMI. Stratification by BMI categories resulted in statistically significant positive associations of BWD and depression in underweight, normal weight, overweight and obese individuals. BWD was associated with depression independent of BMI, sex and age.

Scattered evidence indicates that a lower basal body temperature may be associated with prolonged health span, yet few studies have directly evaluated this relationship. We examined cross-sectional and longitudinal associations between early morning oral temperature (95.0-98.6 °F) and usual gait speed, endurance walk performance, fatigability, and grip strength in 762 non-frail men (52 %) and women aged 65-89 years participating in the Baltimore Longitudinal Study of Aging. Since excessive adiposity (body mass index ≥35 kg/m 2 or waist-to-height ratio ≥0.62) may alter temperature set point, associations were also examined within adiposity strata. Overall, controlling for age, race, sex, height, exercise, and adiposity, lower temperature was associated with faster gait speed, less time to walk 400 m quickly, and lower perceived exertion following 5-min of walking at 0.67 m/s (all p ≤ 0.02). In the non-adipose (N = 662), these associations were more robust (all p ≤ 0.006). Direction of association was reversed in the adipose (N = 100), but none attained significance (all p > 0.22). Over 2.2 years, basal temperature was not associated with functional change in the overall population or non-adipose. Among the adipose, lower baseline temperature was associated with greater decline in endurance walking performance (p = 0.006). In longitudinal analyses predicting future functional performance, low temperature in the non-adipose was associated with faster gait speed (p = 0.021) and less time to walk 400 m quickly (p = 0.003), whereas in the adipose, lower temperature was associated with slower gait speed (p = 0.05) and more time to walk 400 m (p = 0.008). In older adults, lower basal body temperature appears to be associated with healthy aging in the absence of excessive adiposity.

Previous studies listed body surface area (BSA), lean body mass (LBM), and age as modifying factors on the TSH concentrations after administration of recombinant human thyrotropin (rhTSH). The purpose of this study was to identify the main modifying factors on serum TSH levels and to compare the stimulation via single rhTSH injection after a short thyroid hormone withdrawal (THW) with that of the standard stimulating protocol. 106 patients with differentiated thyroid cancer (DTC) undergoing radioiodine therapy (RIT) after rhTSH administration were obtained through chart review. Two groups were evaluated: Group I was treated with a single rhTSH administration after two weeks of T3 therapy followed by one week of THW. Group II was stimulated according to the international standard protocol via rhTSH injections for two consecutive days. Serum TSH concentrations were documented prior to rhTSH administration (day 1 TSH), one day after (day 3 TSH) and 3-6 days after (mean 4.2 days, day 6 TSH) the last rhTSH injection. The following data was collected: age, gender, weight, height, BMI, LBM, BSA, residual thyroid tissue, CRP, creatinine, GFR, liver enzymes, alkaline phosphatase, cholesterol, and triglycerides. Group I: Age combined with anthropometric factors like BMI (TSH increase and day 6 TSH), BSA (TSH decrease), and gender (day 6 TSH) are the main modifying factors on serum TSH concentrations after rhTSH administration. Group II: Age and lean body mass (LBM) showed a significant impact on day 3 TSH, TSH increase (day 3-day 1), and TSH decrease (day 6-day 3). Day 6 TSH was found to be influenced by GFR (group II). Age and anthropometric parameters have significant independent influence on TSH concentrations after rhTSH injection in both groups. Anthropometric parameters (BSA, LBM) and demographic parameters (female gender) show strong influence on TSH concentrations. Further research should be conducted to examine the influence of body compartments on TSH levels

Age differences in attention toward decision-relevant information: education matters.

PubMed

Xing, Cai; Isaacowitz, Derek

2011-01-01

Previous studies suggested that older adults are more likely to engage in heuristic decision-making than young adults. This study used eye tracking technique to examine young adults' and highly educated older adults' attention toward two types of decision-relevant information: heuristic cue vs. factual cues. Surprisingly, highly educated older adults showed the reversed age pattern-they looked more toward factual cues than did young adults. This age difference disappeared after controlling for educational level. Additionally, education correlated with attentional pattern to decision-relevant information. We interpret this finding as an indication of the power of education: education may modify what are thought to be "typical" age differences in decision-making, and education may influence young and older people's decision-making via different paths.

To verify age and education effects on communication performance of healthy adults in the Montreal Communication Evaluation Battery, Portuguese version (MAC-PT). The sample comprised 90 healthy adults from Portugal, European Portuguese speakers, divided into nine groups according to educational level (4-9, 10-13, and > 13 years of formal schooling) and age (19-40, 41-64, and 65-80 years). The influence of age and education was assessed by comparing mean scores between groups, using a two-way analysis of variance followed by Bonferroni post hoc tests (p ≤ 0.05). The results showed that participants' performance was influenced by age in pragmatic-inferential, discursive, and prosodic tasks. Education had the greatest influence on the performance in all processes evaluated by the MAC-PT. Age and education seem to influence the communicative performance and should be considered in the assessment of neurological patients.

The purpose of this study was to determine differences in body size, composition and structure between three somatotypes of Japanese college-aged women. The study sample consisted of 30 sedentary female college students between 18 and 20 years of age. Ten subjects had an endomorphic ectomorph somatotype (mean weight 41.95 kg), 10 had an endomorph-ectomorph somatotype (mean weight 47.12 kg) and the remaining subjects had a mesomorphic endomorph somatotype (mean weight 55.37 kg). The mean heights for these groups did not differ significantly. The mesomorphic endomorph group had a higher gross weight and a higher percentage of all adipose variables than the other two groups, though these measurements were not significantly different between the endomorph-ectomorph and the endomorphic ectomorph groups. The mean lean body weight (LBW) for the mesomorphic endomorph group was significantly larger than that of the other two groups. The endomorph-ectomorph group had the next largest LBW, and the mean for the endomorphic ectomorph group was significantly smaller than that of the other two groups. Inversely, mean values of LBW/weight(WT), LBW/total adipose tissue weight (TATW) ratio and total body water/WT were significantly lower for the mesomorphic endomorph group than for the other two groups. Furthermore, the ratios of internal adipose tissue to weight (IATW)/WT and subcutaneous adipose tissue to IATW (SATW)/IATW did not differ significantly between groups. In conclusion, college-aged women of different somatotypes within the same age and height range varied in body composition. Consequently, the notion of a small frame is incorrect. An accurate assessment of the human body's composition may provide a valuable insight into the ideal weight for optimal physiologic function.

Educational expansion and the education gradient in health: A hierarchical age-period-cohort analysis.

PubMed

2015-11-01

Researchers have recently been investigating the temporal variation in the educational gradient in health. While there is abundant literature concerning age trajectories, theoretical knowledge about cohort differences is relatively limited. Therefore, in analogy with the life course perspective, we introduce two contrasting cohort-specific hypotheses. The diminishing health returns hypothesis predicts a decrease in educational disparities in health across cohorts. By contrast, the cohort accretion hypothesis suggests that the education-health gap will be more pronounced among younger cohorts. To shed light on this, we perform a hierarchical age-period-cohort analysis (HAPC), using data from a subsample of individuals between 25 and 85 years of age (N = 232,573) from 32 countries in the European Social Survey (six waves: 2002-2012). The analysis leads to three important conclusions. First, we observe a widening health gap between different educational levels over the life course. Second, we find that these educational differences in the age trajectories of health seem to strengthen with each successive birth cohort. However, the two age-related effects disappear when we control for employment status, household income, and family characteristics. Last, when adjusting for these mediators, we reveal evidence to support the diminishing health returns hypothesis, implying that it is primarily the direct association between education and health that decreases across cohorts. This finding raises concerns about potential barriers to education being a vehicle for empowerment and the promotion of health. Copyright © 2015 Elsevier Ltd. All rights reserved.

To determine the prevalence rates and level of awareness of obesity among people of different age groups in Morogoro Municipality, Tanzania. A cross-sectional, descriptive study. One hundred adults aged 19-50 years old and 40 pupils aged 14-18 years old. Four educational institutions in Morogoro Municipality were included in the study. The four institutions included a primary and a secondary school, a teacher's training college and a university. The prevalence of obesity among the sampled subjects in Morogoro Municipality was 25 %, whereby 15.7% had a Body Mass Index (BMI) of between 25 and 30, and 9.3% had a BMI of more than 30. Age and occupation of all the subjects, together with marital status of adult subjects, were significantly related with obesity status. Prevalence of obesity increased with the increased age whereby subjects in the 41-50 years had the highest rate (45.4%). Employed subjects had higher rate of obesity (22.2%) than pupils or students. Similarly, married adults had higher rate of obesity (27.8%) than the single ones (4.7%). Unlike the old age group (41-50 years), 70% of the youngest subjects were not aware about the harmful effects of obesity. On the other hand, more than two thirds of all the subjects could not associate excess body weight with chronic non-communicable diseases such as coronary heart disease, high blood pressure and breathing problems. Results of the current study indicate that obesity is increasingly becoming a public health problem in Morogoro Municipality, and probably in many other places in Tanzania. There is need for more public awareness on the effect of obesity on people's health through information, education and communication. It would be of great importance if such interventions were introduced at early age of life, for example by inclusion in school curricula.

Introduction Total body dual-energy x-ray absorptiometry (DXA) data offer the opportunity to compare bone density of demographic groups across the entire skeleton. Methods The present study uses total body DXA data (Hologic QDR 4500A, Hologic Inc, Bedford MA) from the National Health and Nutrition Examination Survey (NHANES) 1999–2004 to examine bone mineral density (BMD) of the total body and selected skeletal subregions in a wide age range of adult men and women from three race/ethnic groups. Total body, lumbar spine, pelvis, right leg, and left arm BMD and lean mass from 13,091 adults age 20 years and older were used. The subregions were chosen to represent sites with different degrees of weight bearing. Results Mean BMD varied in expected ways for some demographic characteristics (men>women and non-Hispanic blacks>non-Hispanic whites) but not others (non-Hispanic whites>Mexican Americans). Differences in age patterns in BMD also emerged for some characteristics (sex) but not others (race/ethnicity). Differences in cross-sectional age patterns in BMD and lean mass by degree of weight-bearing in older adults were observed for the pelvis, leg and arm. Conclusion This information may be useful for generating hypotheses about age, race, and sex differences in fracture risk in the population. PMID:19048179

Obesity: locus of control, body image, weight loss, and age-at-onset.

Wineman, N M

1980-01-01

In a retrospective investigation designed to measure locus of control, body image, and weight loss in Overeaters Anonymous members who had childhood, adolescence, or adulthood onset of obesity, 116 subjects were grouped according to age at onset of obesity and the year they joined OA. A convenience, volunteer sample of OA members completed a demographic data questionnaire, Rotter's Social Reaction. Inventory, and Secord and Jourard's Body Cathexis Scale. Significant overweight percentage differences were not found when the three age-at-onset groups were compared. Significant differences emerged, however, for adolescent-onset group persons who were categorized as "old" members; they had a larger weight loss and were more satisfied with their body image. A positive linear relationship between greater perception of internal control and a good body image was found in the entire adulthood-onset group. Weight loss and good body image of the oldest adolescent-onset group probably was the outcome of their association with a self-help group i.e., OA. Assessment of developmental issues related to the time of initial weight gain may indicate which treatment regime would be most effective.

To explore the relationship between weight status in early adulthood and body weight change at middle age in adults and type 2 diabetes mellitus (T2DM). The data of 14 population samples from China Multicenter Collaborative Study of Cardiovascular Epidemiology conducted in 1998 were used. Approximately 1 000 men and women in each sample were surveyed for cardiovascular disease risk factors, including body weight at age 25 years. The body mass index (BMI) at the age 25 years was calculated. The association between body weight in early adulthood and body weight change at middle age and T2DM was examined by using logistic regression model. The incidence of T2DM in low weight group (BMI<18.5 kg/m(2)), normal weight group (BMI: 18.5-23.9 kg/m(2)), overweight group (BMI: 24.0-27.9 kg/m(2)) and obese group (BMI:≥28.0 kg/m(2)) at 25 years old were 2.4%(30/1263), 2.8%(266/9562), 4.0%(70/1739) and 6.4% (7/110), respectively (P value for trend<0.01). The incidence of T2DM for adults with weight change <-7.5 kg, -7.5--2.6 kg, -2.5-2.5 kg, 2.6-7.5 kg, 7.6-12.5 kg and >12.5 kg at middle age were 2.5% (18/712), 1.3%(21/1629), 2.1%(48/2330), 2.3%(59/2585), 3.7%(94/2518), and 4.6% (133/2900) respectively. (P value for trend <0.01), Multivariate logistic regression analysis showed that overweight and obesity at age 25 years and subsequent weight gain were positively correlated with T2DM after adjusted other risk factors (all P values for trend <0.01). Overweight and obesity in early adulthood and weight gain at middle age were both independently associated with the increased risk of T2DM in middle-aged men and women.

Long-term exercise in mice has sex-dependent benefits on body composition and metabolism during aging.

Aging is associated with declining exercise and unhealthy changes in body composition. Exercise ameliorates certain adverse age-related physiological changes and protects against many chronic diseases. Despite these benefits, willingness to exercise and physiological responses to exercise vary widely, and long-term exercise and its benefits are difficult and costly to measure in humans. Furthermore, physiological effects of aging in humans are confounded with changes in lifestyle and environment. We used C57BL/6J mice to examine long-term patterns of exercise during aging and its physiological effects in a well-controlled environment. One-year-old male (n = 30) and female (n = 30) mice were divided into equal size cohorts and aged for an additional year. One cohort was given access to voluntary running wheels while another was denied exercise other than home cage movement. Body mass, composition, and metabolic traits were measured before, throughout, and after 1 year of treatment. Long-term exercise significantly prevented gains in body mass and body fat, while preventing loss of lean mass. We observed sex-dependent differences in body mass and composition trajectories during aging. Wheel running (distance, speed, duration) was greater in females than males and declined with age. We conclude that long-term exercise may serve as a preventive measure against age-related weight gain and body composition changes, and that mouse inbred strains can be used to characterize effects of long-term exercise and factors (e.g. sex, age) modulating these effects. These findings will facilitate studies on relationships between exercise and health in aging populations, including genetic predisposition and genotype-by-environment interactions. © 2016 The Authors.

Weber, Daniela

2016-01-28

Physical functioning and mobility of older populations are of increasing interest when populations are aging. Lower body functioning such as walking is a fundamental part of many actions in daily life. Limitations in mobility threaten independent living as well as quality of life in old age. In this study we examine differences in physical aging and convert those differences into the everyday measure of single years of age. We use the English Longitudinal Study of Ageing, which was collected biennially between 2002 and 2012. Data on physical performance, health as well as information on economics and demographics of participants were collected. Lower body performance was assessed with two timed walks at normal pace each of 8 ft (2.4 m) of survey participants aged at least 60 years. We employed growth curve models to study differences in physical aging and followed the characteristic-based age approach to illustrate those differences in single years of age. First, we examined walking speed of about 11,700 English individuals, and identified differences in aging trajectories by sex and other characteristics (e.g. education, occupation, regional wealth). Interestingly, higher educated and non-manual workers outperformed their counterparts for both men and women. Moreover, we transformed the differences between subpopulations into single years of age to demonstrate the magnitude of those gaps, which appear particularly high at early older ages. This paper expands research on aging and physical performance. In conclusion, higher education provides an advantage in walking of up to 15 years for men and 10 years for women. Thus, enhancements in higher education have the potential to ensure better mobility and independent living in old age for a longer period.

To estimate lean body mass (LBM) in preschool aged boys and girls in India and explore gender difference. Crossectional. Immunization clinic of a charitable Government General Hospital in Kolkata, India. Two-hundred and forty-five children (147 boys and 98 girls) aged 1-5 y from among the urban poor were admitted in the study between July 1999 and December 2000. Children with acute or chronic illness or congenital malformation were excluded. Length/height to the nearest 0.1 cm, weight to the nearest 10 g and total body resistance using multifrequency bioelectrical (Xitron 4000B) impedance analyzer (BIA) at 50 kHz were measured. Their nutritional status was compared with National Center for Health Statistics (NCHS) median data and lean body mass (LBM) was calculated using anthropometry and BIA equations. The groups were compared using analysis of variance and multiple linear regression. Girls were more stunted (P<0.001) and underweight (P<0.047), while the degree of wasting was similar. Mean LBM percentage was higher in boys compared with girls by anthropometry (P<0.001) and BIA (P<0.005), which persisted after adjusting for age. With increasing age, LBM percentage declined in girls (P<0.02) in contrast to reference girls, in whom it increased. In boys LBM percentage increased with age as is in reference boys. In addition to the girls being more stunted and underweight, LBM% decreased in girls with increasing age but steadily increased in boys, suggesting hidden deprivation of female children.

Age and Embodied Masculinities: Mid-Life Gay and Heterosexual Men Talk about their Bodies

PubMed Central

Lodge, Amy C.; Umberson, Debra

2013-01-01

This article integrates critical gerontology and masculinities theories to examine how midlife gay and heterosexual men experience their bodies in relation to cultural discourses of aging. Analyses of in-depth interviews with 15 gay and 15 heterosexual men ages 40–60 reveal that while both groups of men describe their bodies as deteriorating or declining in terms of functionality and are often distressed by these changes, midlife gay men also articulate a concern with a perceived decline in bodily appearance. Both gay and heterosexual midlife men frame their bodies as fundamentally different from women’s, possibly in an attempt to protect a masculine identity in response to the threat that aging bodies pose to that identity. We argue that midlife men’s embodied experiences are shaped by a discourse of midlife decline as well as inequalities between gay and heterosexual men. We also discuss the implications of embodiment for midlife men’s well-being. PMID:23849420

Low BMI is a risk factor for osteoporosis, but it is not clear if relationships between BMI, lean mass (LM), fat mass (FM) and BMD are consistent across different levels of BMI. We studied 1929 Caucasian participants (1014 females) aged 45-66years in the Busselton Healthy Ageing Study in Western Australia. Body composition and BMD of total body, lumbar spine, total hip and femoral neck were measured using DXA. From generalized additive models, the positive relationships between BMI and BMD were weaker at high BMI, particularly at the spine and in males. In the entire cohort, adjusting for relevant covariates, LM and FM were significant predictors of all BMD measures in both genders. In men, analysis by tertiles of BMI showed that LM and FM (in kg) were positively associated with BMD (in mg/cm(2)) in tertile 1 except for LM and spine BMD (LM β: 5.18-6.80, FM β: 3.38-9.24, all P<0.05), but not in the middle or upper tertiles (LM β: -3.12-3.07, FM β: -4.75-1.82, P>0.05). In women, LM was positively associated with BMD in each tertile of BMI, except for spine BMD in the upper tertile, with regression coefficients lower in the upper tertile (β: 5.16-9.95, 5.76-9.56 and 2.80-5.78, respectively, all P<0.05). FM was positively associated with total body, spine and total hip BMD in women in BMI tertile 1 (β: 2.86-6.68, P<0.05); these associations were weaker or absent in the middle and upper tertiles. In conclusion, in middle-aged adults the positive relationships between lean or fat mass with BMD among those with higher BMI are absent in males and weaker in females. Copyright © 2015 Elsevier Inc.

Background Despite comparatively lower socioeconomic status (SES), immigrants tend to have lower body weight and weaker SES gradients relative to U.S.-born individuals. Yet, it is unknown how changes in SES over the life-course relate to body weight in immigrants versus US-born individuals. Methods We used longitudinal data from a nationally-representative, diverse sample of 13701 adolescents followed into adulthood to investigate whether associations between SES mobility categories (educational attainment reported by individuals as adults and by their parents during adolescence) and body mass index (BMI) measured in adulthood varied by immigrant generation. Weighted multivariable linear regression models were adjusted for age, sex, race/ethnicity, and immigrant generation. Results Among first generation immigrants, although parental education was not associated with adult BMI, an immigrant’s own education attainment was inversely associated with BMI (β=−2.6 kg/m2; standard error (SE)=0.9, p<0.01). In addition, upward educational mobility was associated with lower adult mean BMI than remaining low SES (β= −2.5 kg/m2; SE=1.2, p<0.05). In contrast, among U.S.-born respondents, college education in adulthood did not attenuate the negative association between parental education and adult BMI. Although an SES gradient emerged in adulthood for immigrants, remaining low SES from adolescence to adulthood was not associated with loss of health advantage relative to U.S.-born respondents of U.S.-born parents of similar SES. Conclusion Immigrants were able to translate higher SES in adulthood into a lower adult mean BMI regardless of childhood SES, whereas the consequences of lower childhood SES had a longer reach even among the upwardly mobile U.S.-born.

The educational mobility of mid-age women is rarely studied. We analysed the baseline socio-economic position (SEP) and health factors associated with obtaining further education in 4117 mid-age Australian women between 1996 and 2010 (aged 45-50 at baseline, 62-67 at follow-up) from a population-based study. Women either unemployed or working part-time at baseline had higher odds of a stable low and middle education over time (ORs ranging from 1.61 to 3.86) versus educational mobility. Apart from obesity, characteristics that may signal an unhealthy lifestyle in early mid-life were not useful indicators of women's future educational mobility. Copyright © 2016 Elsevier Ireland Ltd.

Few studies have investigated differences in age- and gender-specific educational gradients in tobacco smoking among the whole range of adult age groups. We examined educational inequality in smoking among Japanese adults aged 25-94 years. Using a large nationally representative sample (167,925 men and 186,588 women) in 2010, prevalence of current smoking and heavy smoking among daily smokers and their inequalities attributable to educational attainment were analyzed according to sex and age groups. Among men aged 25-34 years, junior high school graduates had the highest current smoking prevalence at 68.4% (95% confidence interval [CI], 66.0%-70.6%), and graduate school graduates had the lowest at 19.4% (95% CI, 17.2%-21.9%). High school graduates had the second highest current smoking prevalence (e.g., 55.9%; 95% CI, 54.9%-56.8% in men aged 25-34 years). Among men aged 75-94 years, the difference in current smoking across educational categories was small. A similar but steeper educational gradient in current smoking was observed among women. Among women aged 25-34 years, junior high school graduates had the highest current smoking prevalence at 49.3% (95% CI, 46.3%-52.3%), and graduate school graduates had the lowest at 4.8% (95% CI, 2.9%-7.4%). Compared with older age groups, such as 65-94 years, younger age groups, such as 25-54 years, had higher estimates of inequality indicators for educational inequality in both current and heavy smoking in both sexes. Educational inequalities in current and heavy smoking were apparent and large in the young population compared with older generations. The current study provides basic data on educational inequalities in smoking among Japanese adults. Copyright © 2016 The Authors. Production and hosting by Elsevier B.V. All rights reserved.

Age-related factors in the relationship between foot measurements and living stature and body weight.

PubMed

Atamturk, Derya; Duyar, Izzet

2008-11-01

The measurements of feet and footprints are especially important in forensic identification, as they have been used to predict the body height and weight of victims or suspects. It can be observed that the subjects of forensic-oriented studies are generally young adults. That is to say, researchers rarely take into consideration the body's proportional changes with age. Hence, the aim of this study is to generate equations which take age and sex into consideration, when stature and body weight are estimated from foot and footprints dimensions. With this aim in mind, we measured the stature, body weight, foot length and breadth, heel breadth, footprint length and breadth, and footprint heel breadth of 516 volunteers (253 males and 263 females) aged between 17.6 and 82.9 years using standard measurement techniques. The sample population was divided randomly into two groups. Group 1, the study group, consisted of 80% of the sample (n = 406); the remaining 20% were assigned to the cross-validation group or Group 2 (n = 110). In the first stage of the study, we produced equations for estimating stature and weight using a stepwise regression technique. Then, their reliability was tested on Group 2 members. Statistical analyses showed that the ratios of foot dimensions to stature and body weight change considerably with age and sex. Consequently, the regression equations which include these variables yielded more reliable results. Our results indicated that age and sex should be taken into consideration when predicting human body height and weight for forensic purposes.

This study assessed how different measures of body composition predict physical performance ten years later among older adults. The participants were 1076 men and women aged 57 to 70 years. Body mass index (BMI), waist circumference, and body composition (bioelectrical impedance analysis) were measured at baseline and physical performance (Senior Fitness Test) ten years later. Linear regression analyses were adjusted for age, education, smoking, duration of the follow-up and physical activity. Greater BMI, waist circumference, fat mass, and percent body fat were associated with poorer physical performance in both sexes (standardized regression coefficient [β] from -0.32 to -0.40, p < 0.001). Lean mass to BMI ratio was positively associated with later physical performance (β = 0.31 in men, β = 0.30 in women, p < 0.001). Fat-free mass index (lean mass/height 2 ) in both sexes and lean mass in women were negatively associated with later physical performance. Lean mass residual after accounting for the effect of height and fat mass was not associated with physical performance. Among older adults, higher measures of adiposity predicted poorer physical performance ten years later whereas lean mass was associated with physical performance in a counterintuitive manner. The results can be used when appraising usefulness of body composition indicators for definition of sarcopenic obesity. Copyright © 2018 Elsevier B.V. All rights reserved.

To study the relationship of winter 25-hydroxycholecalciferol (25-OHD) levels with age, education, place of residency, marital status and body mass index (BMI) as they may affect sun exposure, vitamin D synthesis and metabolism. Subjects (1952) answered a structured questionnaire concerning education, marital status and smoking; and body weight/height, and parathyroid hormone and 25-OHD were measured. 25-OHD levels were higher in the males with elementary and secondary education compared with higher education (46.8±18.5 and 43.7±16 vs 39.9±15.3 nmol/l, P<0.01). Vitamin D deficiency was more prevalent (16.7%, (13.1-20.2) vs 10.8%, (8.4-13.2), P=0.08) and sufficiency was less prevalent (24.6% (20-29.2) vs 33.7%, (29.5-37.8), P=0.005) in those with higher than secondary education. No differences were found among the females. Male smokers had lower 25-OHD than nonsmokers (40.2±16.6 vs 43.6±15.7 nmol/l, P=0.004). Deficiency was more prevalent in the male smokers than nonsmokers with secondary and higher education (secondary 16.6%, (10.1-22.4) vs 8.2%, (5.1-11.3), P=0.006; higher 27.4%, (17.7-37.1) vs 13.2%, (9.0-17.5), P=0.003). 25-OHD was lower in the obese than in the normal-weight females (34.6±16.2 vs 38.2±17.8 nmol/l, analysis of variance, P=0.014), but not males. Marital status was not related to 25-OHD. Only in the urban residents, increasing BMI in the young females increased the risk for vitamin D deficiency by 1%, and smoking had an odds ratio of 1.99 (1.05-3.78) in the young and 2.5 (1.07-5.75) in the middle-aged males. Smoking and higher education in the males and obesity in the females were factors for vitamin D deficiency among Bulgarian urban population.

In adulthood, conscientiousness and neuroticism are correlates of body weight and weight gain. The present research examines whether the childhood antecedents of these traits, persistence and negative reactivity, respectively, are associated with weight gain across childhood. We likewise examine sociability as a predictor of childhood weight gain and whether these three traits are associated with weight concerns and weight-management strategies in adolescence. Participants (N=4153) were drawn from the Longitudinal Study of Australian Children, an ongoing, population-based study of child and family health and well-being. At the baseline assessment, caregivers reported on their child's temperament. At every assessment from ages 4-5 to 14-15 years, study children were weighed and measured by trained staff; there were up to six biennial assessments of body mass index and waist circumference. At ages 14-15 years, study children (n=2975) also self-reported on their weight concerns and weight-management strategies. Study children rated lower in persistence or higher in negative reactivity in early childhood gained more weight between the ages of 4 and 15 years. Sociability was associated with weight gain among girls but not among boys. Lower persistence and higher negative reactivity at ages 4-5 years were also associated with greater weight concerns, restrained eating and use of unhealthy weight-management strategies at ages 14-15 years. Childhood traits related to conscientiousness and neuroticism are associated with objective weight gain across childhood and with concerns and strategies to manage weight in adolescence. These results are consistent with a lifespan perspective that indicates that trait psychological functioning contributes to health-related markers from childhood through old age.

2015-04-01

A new and novel approach of predicting the body weight of children based on age and morphological facial features using a three-layer feed-forward artificial neural network (ANN) model is reported. The model takes in four parameters, including age-based CDC-inferred median body weight and three facial feature distances measured from digital facial images. In this study, thirty-nine volunteer subjects with age ranging from 6-18 years old and BW ranging from 18.6-96.4 kg were used for model development and validation. The final model has a mean prediction error of 0.48, a mean squared error of 18.43, and a coefficient of correlation of 0.94. The model shows significant improvement in prediction accuracy over several age-based body weight prediction methods. Combining with a facial recognition algorithm that can detect, extract and measure the facial features used in this study, mobile applications that incorporate this body weight prediction method may be developed for clinical investigations where access to scales is limited. © 2014, The American College of Clinical Pharmacology.

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

PubMed

Slagsvold, Britt; Sørensen, Annemette

2008-01-01

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.

2014-01-01

This study aimed to provide data concerning the validity of a short sequence of face valid pictorial stimuli assessing the perception of body size in school-age children. A sequence of gender and age-appropriate silhouettes was administered to 314 boys and girls aged 6-14 years. The self-evaluations provided by the children correlated significantly with their actual BMI corrected for age. Furthermore, the children's self-evaluations always significantly correlated with the evaluations provided by the three external observers; i.e., both parents and the interviewers. The results indicate that this sequence of pictorial stimuli, depicting realistic human forms appropriate for children, is a valid measure of children's body image. Relevant differences across age groups were also found, indicating that before the age of eight, the correlations between the children's self-evaluations and their BMI or the judgments of the three observers are lower than in the other age groups.

The goal was to determine the age-related changes in accommodative movements of the lens and ciliary body in rhesus monkeys. Varying levels of accommodation were stimulated via the Edinger-Westphal (E-W) nucleus in 26 rhesus monkeys, aged 6-27 years, and the refractive changes were measured by coincidence refractometry. Centripetal ciliary process (CP) and lens movements were measured by computerized image analysis of goniovideographic images. Ultrasound biomicroscopy (UBM) at 50 MHz was used to visualize and measure accommodative forward movements of the ciliary body in relation to age, accommodative amplitude, and centripetal CP and lens movements. At ∼3 diopters of accommodation, the amount of centripetal lens movement required did not significantly change with age (p=0.10; n=18 monkeys); however, the amount of centripetal CP movement required significantly increased with age (p=0.01; n=18 monkeys), while the amount of forward ciliary body movement significantly decreased with age (p=0.007; n=11 monkeys). In the middle-aged animals (12-16.5 years), a greater amount of centripetal CP movement was required to induce a given level of lens movement and thereby a given level of accommodation (p=0.01), compared to the young animals (6-10 yrs). Collectively, the data suggests that, with age, the accommodative system may be attempting to compensate for the loss of forward ciliary body movement by increasing the amount of centripetal CP movement. This, in turn, would allow enough zonular relaxation to achieve the magnitude of centripetal lens movement necessary for a given amplitude of accommodation. PMID:19635475

Caloric restriction (CR) has been shown to increase the life span and health span of a broad range of species. However, CR effects on in vivo brain functions are far from explored. In this study, we used multimetric neuroimaging methods to characterize the CR-induced changes of brain metabolic and vascular functions in aging rats. We found that old rats (24 months of age) with CR diet had reduced glucose uptake and lactate concentration, but increased ketone bodies level, compared with the age-matched and young (5 months of age) controls. The shifted metabolism was associated with preserved vascular function: old CR rats also had maintained cerebral blood flow relative to the age-matched controls. When investigating the metabolites in mitochondrial tricarboxylic acid cycle, we found that citrate and α-ketoglutarate were preserved in the old CR rats. We suggest that CR is neuroprotective; ketone bodies, cerebral blood flow, and α-ketoglutarate may play important roles in preserving brain physiology in aging. Copyright © 2015 The Authors.

Low socio-economic status is increasingly being identified as a risk marker for chronic diseases, but few studies have investigated the link between socio-economic factors and age-related macular degeneration (AMD). The present study aimed to assess the association between socio-economic status and the prevalence of AMD. A population-based cross-sectional study of 3280 (78.7% response rate) Malay adults aged 40-80 years residing in 15 south-western districts of Singapore. AMD was graded from retinal photographs at a central reading centre using the modified Wisconsin AMD scale. Early and late AMD signs were graded from retinal photographs following the Wisconsin grading system. Socio-economic status including education, housing type and income were determined from a detailed interview. Of the participants, 3265 had photographs of sufficient quality for grading of AMD. Early AMD was present in 168 (5.1%) and late AMD in 21 (0.6%). After adjusting for age, gender, smoking, hypertension, diabetes and body mass index, participants with lower educational levels were significantly more likely to have early AMD (multivariate OR 2.2, 95% CI 1.2 to 4.0). This association was stronger in persons who had never smoked (multivariate OR 3.6, 95% confidence CI 1.4 to 9.4). However, no association with housing type or income was seen. Low educational level is associated with a higher prevalence of early AMD signs in our Asian population, independent of age, cardiovascular risk factors and cigarette smoking.

Objective In Brazil, information about the influence of body image on the various life domains of women in menopausal transition is scarce. Thus, the objective of the study was to analyze the relationship between body image and quality of life in middle-aged Brazilian women. Methods This was a cross-sectional study of 250 women between 40 and 65 years old, living in Parnamirim/RN, Brazil, who were evaluated in relation to body image and quality of life. For body image, women were classified as: dissatisfied due to low weight, satisfied (with their body weight) and dissatisfied due to being overweight. Quality of life was assessed through a questionnaire in which higher values indicate higher quality of life. Multiple linear regression was performed to analyze the relationship between body image and quality of life, adjusted for covariates that presented p<0.20 in the bivariate analysis. Results The average age was 52.1 (± 5.6) years, 82% of the women reported being dissatisfied due to being overweight, and 4.4% were dissatisfied due to having low weight. After multiple linear regression analyzes, body image remained associated with health (p<0.001), emotional (p = 0.016), and sexual (p = 0.048) domains of quality of life, as well as total score of the questionnaire (p<0.001). Conclusion Women who reported being dissatisfied with their body image due to having low weight or overweight had worse quality of life in comparison to those who were satisfied (with their body weight).

We used multivariable regression to examine the associations between total and trimester gestational weight gain (GWG) and birth weight for gestational age and child BMI outcomes, adjusting for maternal age, race/ethnicity, education, marital status, parity, pre-pregnancy body mass index (BMI), and smoking; paternal overweight, gestational age, and infant sex. We explored differences in associations by maternal BMI and infant sex. GWG in all trimesters was significantly and independently associated with birth weight with associations stronger, though not significantly, in the second trimester. First trimester GWG was associated with child BMI outcomes (OR for child overweight = 1.05; 95% CI = 1.02, 1.09). Each kg of first trimester GWG was significantly associated with increased child BMI z-score in women of low (β = 0.099; 95% CI = 0.034, 0.163) and normal (β = 0.028; 95% CI = 0.012, 0.044), but not high pre-pregnancy BMI. GWG in all trimesters was associated with birth weight; only first trimester GWG was associated with child BMI. If replicated, this information could help specify recommendations for maternal GWG and elucidate mechanisms connecting GWG to child BMI.

In this article, we empirically study the role of education attainment on individual body mass index (BMI), eating patterns, and physical activity. We allow for endogeneity of schooling choices for females and males in a mean and quantile instrumental variables framework. We find that completion of lower secondary education has a significant positive impact on reduction of individual BMI, containment of calorie consumption, and promotion of physical activity. Interestingly, these effects are heterogeneous across genders and distributions. In particular, for BMI and calorie expenditure, the effect of education is significant for females and is more pronounced for women with high body mass and low physical activity. On the other hand, the effect of education on eating patterns is significant mainly for males, being more beneficial for men with elevated calorie consumption. We also show that education attainment is likely to foster productive and allocative efficiency of individuals in the context of BMI formation. Given that the literature suggests that education fosters development of cognition, self-control, and a variety of skills and abilities, in our context it is thus likely to promote lifetime preferences and means of individuals, which in turn enable them to achieve better health outcomes. Education also provides exposure to physical education and to school subjects enhancing individual deliberative skills, which are important factors shaping calorie expenditure and intake. Finally, we show that in the presence of strong socioeconomic inequalities in BMI, education is likely to have a pronounced impact on healthy BMI for the disadvantaged groups, represented in our framework by females.

Scant evidence is available worldwide on the relative influence of occupational social class and educational level on body concentrations of persistent organic pollutants (POPs) in the general population. The objective was to analyse such influence in a representative sample of the general population of Catalonia, Spain. Participants in the Catalan Health Interview Survey aged 18-74 were interviewed face-to-face, gave blood, and underwent a physical exam. The role of age, body mass index (BMI), and parity was analysed with General Linear Models, and adjusted geometric means (GMs) were obtained. Crude (unadjusted) concentrations were higher in women and men with lower education, and in women, but not men, in the less affluent social class. After adjusting for age, in women there were no associations between POP levels and social class or education. After adjusting for age and BMI, men in the less affluent class had higher p,p'-DDE concentrations than men in class I (p-value=0.016), while men in class IV had lower HCB than men in the upper class (p-value<0.03). Also in contrast with some expectations, positive associations between education and POP levels were observed after adjusting for age and BMI in men; e.g., men with university studies had higher HCB concentrations than men with first stage of primary schooling (adjusted GM 153.9 and 80.5ng/g, respectively) (p-value<0.001). When education and social class were co-adjusted for, some positive associations with education in men remained statistically significant, whereas class remained associated only with p,p'-DDE. Educational level influenced blood concentrations of POPs more than occupational social class, especially in men. In women, POP concentrations were mainly explained by age/birth cohort, parity and BMI. In men, while concentrations were also mainly explained by age/birth cohort and BMI, both social class and education showed positive associations.

The aim of this study is to evaluate the association between body image dissatisfaction and measurements of obesity - body mass index, waist circumference and body fat percentage - in students aged 7 to 10years in Florianopolis, Santa Catarina. Body image dissatisfaction was assessed by the Figure Rating Scale for Brazilian children. Association analyses were performed using multinomial logistic regression. Body dissatisfaction was prevalent in 82.9% of the students, of whom 59.9% desired a smaller body size and 23.0% desired a larger body size, with a significant difference between the sexes. In boys, overweight, obesity and central obesity remained associated with the desire for a smaller body size, whereas for girls overweight and excess body fat were associated with the desire for a smaller body size. The results point to a normative discontent and indicate the need to include the topic of body image in the school curriculum. Copyright © 2016 Elsevier Inc. All rights reserved.

We examined relationships between repression, general maladjustment, body mass index (BMI), and waist-to-hip ratio (WHR). The participants were 1,081 healthy older men from the Normative Aging Study. Repression and General Maladjustment Scales of the Minnesota Multiphasic Personality Inventory were composite measures of personality. Repression was associated with lower BMI and WHR, and maladjustment with higher BMI and WHR. However, associations between WHR and personality dimensions were no longer significant when controlling for BMI, but associations between BMI and personality dimensions remained significant when controlling for WHR. These effects were explained by differing relationships between WHR, repression, and maladjustment for normal weight, overweight, and obese individuals. Specifically, associations between repression, maladjustment, and body shape were significant for normal weight and overweight individuals, but not for obese individuals. Health behaviors including smoking did not mediate relationships between repression, maladjustment, and body shape, but might be considered in future studies as mechanisms underlying links between personality and body shape.

Background. Understanding the physiological, chemical, and biophysical characteristics of the skin helps us to arrange a proper approach to the management of skin diseases. Objective. The aim of this study was to measure 6 biophysical characteristics of normal skin (sebum content, hydration, transepidermal water loss (TEWL), erythema index, melanin index, and elasticity) in a normal population and assess the effect of sex, age, and body location on them. Methods. Fifty healthy volunteers in 5 age groups (5 males and females in each) were enrolled in this study. A multifunctional skin physiology monitor (Courage & Khazaka electronic GmbH, Germany) was used to measure skin sebum content, hydration, TEWL, erythema index, melanin index, and elasticity in 8 different locations of the body. Results. There were significant differences between the hydration, melanin index, and elasticity of different age groups. Regarding the locations, forehead had the highest melanin index, where as palm had the lowest value. The mean values of erythema index and melanin index and TEWL were significantly higher in males and anatomic location was a significant independent factor for all of 6 measured parameters. Conclusion. Several biophysical properties of the skin vary among different gender, age groups, and body locations. PMID:22536139

Many patients with type 2 diabetes find it difficult to maintain good glycemic control. Undesirable glycemic control occurs greatly due to deficiencies of nutritional knowledge and difficulty in obtaining dietary prescriptions. The late middle-aged and elder individuals are the main populations that are affected by type 2 diabetes. The main purpose of this study was to investigate whether intensive nutrition education would make benefits for late middle-aged patients with type 2 diabetes. 196 patients between 50 to 65 years old meeting type 2 diabetes criteria and eligible for the program were included in a single-blinded, 30-day centralized management of an education program in China. Participants in the program were randomly divided into a usual nutrition education group or an intensive nutrition education group. The usual nutrition education group was used as a control group and received only basic health advice and principles of diabetic diets at the beginning and the end of the study. Participants in the intensive nutrition education group were arranged to receive intensive nutritional lectures about diabetes for 30 days. The primary outcomes were the changes in weight, body mass index (BMI), fasting plasma glucose (FPG), 2-h postprandial plasma glucose (PG), glycosylated hemoglobin (HbA1c), total glycerin (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-c), and low-density lipoprotein cholesterol (LDL-c). After 30 days of intervention, FPG, PG, and HbA1c in the treatment group decreased significantly than the control group (p < 0.05). HbA1c reduced significantly by 0.6% in the intervention group. No significant differences in the change of blood lipids were observed between groups. However, TG, TC, and HDL-c made improvements compared with the baseline in the experimental group. Both groups had a reduction in weight and BMI within groups, especially in intensive nutrition education group. However, there was no statistical significance

A growing body of evidence demonstrated that it is feasible to induce ownership over an artificial body to alter bodily experience. However, several uncharted aspects about full-body illusion applications need to be tackled before a complete exploitation of these methods in clinical practice. This work is devoted to explore possible individual age-related differences in shaping changes in body representations induced with a full-body illusion. A total of 40 women were divided into two different age groups according to the median of the variable age. Participants estimated the width of three different body parts (i.e., shoulders, abdomen, and hips) before the entire illusion was induced (baseline), and after the synchronous and the asynchronous conditions. Results revealed that 26-to-55-year-old participants were more resistant to changes induced by the bodily illusion, whereas 19-to-25-year-old participants underestimated their bodies after both conditions. The findings were discussed in terms of the literature exploring age differences in responses to bodily illusion, which could suggest a Bayesian mechanism underlying these individual differences.

The influences of age, physical activity, and body anthropometry on calcaneal speed of sound are different among young adults, middle-aged, and elderly men. Quantitative ultrasound assessment of bone health status is much needed for developing countries in the screening of osteoporosis, but further studies on the factors that influence the quantitative ultrasound indices are required. The present study examined the influence of age, lifestyle factors, and body anthropometry on calcaneal speed of sound (SOS) in a group of Malaysian men of diverse age range. A cross-sectional study was conducted, and data from 687 eligible males were used for analysis. They answered a detailed questionnaire on their physical activity status, and their anthropometric measurements were taken. Their calcaneal SOS values were evaluated using the CM-200 sonometer (Furuno, Nishinomiya City, Japan). Subjects with higher body mass index (BMI) had higher calcaneal SOS values albeit significant difference was only found in the elderly subjects (p < 0.05). Sedentary subjects had lower calcaneal SOS values than physically active subjects, but significant difference was only found in the middle-aged subjects (p < 0.05). Calcaneal SOS was significantly (p < 0.05) correlated with age in young men; height, BMI, and physical activity score in middle-aged men; height and physical activity score in elderly men; and age and physical activity score for overall subjects. In a multivariate regression model, significant (p < 0.05) predictors for calcaneal SOS included age for young men; physical activity, BMI, body fat percentage, and height for middle-aged men; height for elderly men; and age, height, physical activity, weight, and body fat percentage for overall subjects. Age, body anthropometry, and physical activity level have significant effects on the calcaneal SOS value in men.

To investigate factors affecting the low lean body mass (LBM) of young women, we focused on the increase in body weight until one year of age and current lifestyles. In 442 young women, the increase in body weight from birth until one year of age, breast-feeding method in infancy, current physique index and body composition, and physique and lifestyles were investigated using a questionnaire. Subjects with an LBM percentile of less than 33.3 (less than 36.8 kg) were classified as having a low LBM (n = 150), and those with a 33.3 or higher LBM percentile as the control (n = 293). Based on body weight changes from birth to days 3 and 7, the subjects were divided into a rapid weight gain group and two non-rapid weight gain groups (groups 1-3). To analyze factors involved in a low LBM, multivariate analysis using a logistic model was employed. The prevalence of a low LBM in the rapid weight gain group was 0.41 times higher than in the others. The prevalence of a low LBM with a low birth weight was 0.58 times higher, indicating that a low birth weight is likely to result in a low LBM. Regarding the lifestyles, the prevalence of a low LBM in subjects with a current breakfasting habit was 0.60 times higher than in those without one. These findings suggest that the thinness of young women characterized by a low LBM is associated with the increase in body weight until one year of age and current lifestyles.

Studying mechanisms underlying social inequality in postmenopausal breast cancer is important in order to develop prevention strategies. Standard methods for investigating indirect effects, by comparing crude models to adjusted, are often biased. We applied a new method enabling the decomposition of the effect of educational level on breast cancer incidence into indirect effects through reproductive patterns (parity and age at first birth), body mass index and health behavior (alcohol consumption, physical inactivity, and hormone therapy use). The study was based on a pooled cohort of 6 studies from the Copenhagen area including 33,562 women (1,733 breast cancer cases) aged 50–70 years at baseline. The crude absolute rate of breast cancer was 399 cases per 100,000 person-years. A high educational level compared to low was associated with 74 (95% CI 22–125) extra breast cancer cases per 100,000 person-years at risk. Of these, 26% (95% CI 14%–69%) could be attributed to alcohol consumption. Similar effects were observed for age at first birth (32%; 95% CI 10%–257%), parity (19%; 95%CI 10%–45%), and hormone therapy use (10%; 95% CI 6%–18%). Educational level modified the effect of physical activity on breast cancer. In conclusion, this analysis suggests that a substantial number of the excess postmenopausal breast cancer events among women with a high educational level compared to a low can be attributed to differences in alcohol consumption, use of hormone therapy, and reproductive patterns. Women of high educational level may be more vulnerable to physical inactivity compared to women of low educational level. PMID:24205296

Limited research has quantified variation in the characteristics of the breasts among women and determined how these breast characteristics are influenced by age and body mass. The aim of this study was to classify the breasts of women in the community into different categories based on comprehensive and objective measurements of the characteristics of their breasts and torsos, and to determine the effect of age and body mass index (BMI) on the prevalence of these breast categories. Four breast characteristic clusters were identified (X-Large, Very-ptotic & Splayed; Large, Ptotic & Splayed; Medium & Mildly-ptotic; and Small & Non-ptotic), with age and BMI shown to significantly affect the breast characteristic clusters. These results highlight the difference in breast characteristics exhibited among women and how these clusters are affected by age and BMI. The breast characteristic clusters identified in this study could be used as a basis for future bra designs and sizing systems in order to improve bra fit for women.

Overweight and obesity are important predictors of a wide variety of health problems. Analysis of naturally occurring changes in body weight can provide valuable insights in improving our understanding of the influence of demographic, lifestyle, and psychosocial factors on weight gain in middle-age adults. To identify gender-specific predictors of body weight using cross-sectional and longitudinal analyses. Anthropometric, lifestyle and psychosocial factors were measured at baseline and then quarterly for 1 year in 572 healthy adult volunteers from Central Massachusetts who were recruited between 1994 and 1998. Linear mixed models were used to analyze the relationship between body weight and potential predictors, including demographic (e.g., age, educational level), lifestyle (e.g., diet, physical activity, smoking), and psychosocial (e.g., anxiety, depression) factors. Over the 1-year study period, on average, men gained 0.3 kg and women lost 0.2 kg. Predictors of lower body weight at baseline in both men and women included current cigarette smoking, greater leisure-time physical activity, and lower depression and anxiety scores. Lower body weights were associated with a lower percentage of caloric intake from protein and greater occupational physical activity levels only among men; and with higher education level only among women. Longitudinal predictors of 1-year weight gain among women included increased total caloric intake and decreased leisure-time physical activity, and among men, greater anxiety scores. Demographic, lifestyle and psychosocial factors are independently related to naturally occurring changes in body weight and have marked differential gender effects. These effects should be taken into consideration when designing interventions for weight-loss and maintenance at the individual and population levels.

Our study aimed to describe the temporal changes in self-rated health status (SRH) from 1997 to 2012 in adults aged 25 to 84 residing in Switzerland, with a view to identifying groups at risk for declining health. Secondary analysis of population-based cross-sectional health surveys. Data were collected from the cross-sectional, population-based, five-year Swiss Health Survey, from 1997, 2002, 2007 and 2012. A total of 63,861 individuals' data were included. Multilevel mixed-effect logistic regression analysis was employed to estimate the probability of very good and good health within the framework of a hierarchical cross-classified age-period-cohort model (HAPC), adjusting for education level, gender, civil status, smoking status and body mass index. Individuals with higher education were substantially more likely than those with primary education to report good SRH (OR = 2.12; 95% CI = 1.93-2.33 for secondary education and OR = 3.79; 95% CI = 3.39-4.23 for tertiary education). The education effect depended on birth cohort and age: higher proportions of good SRH were reported by secondary (8%-17%) and tertiary (10%-22%) compared with primary educated individuals from the 1940 birth cohort onward; the proportion of secondary/tertiary (compared to primary) educated people reporting good SRH increased with age (by 10/11% at 45-50 years and 25/36% at 80-84 years). Gender health equality was achieved by the 1955 (primary educated) and 1960 (secondary educated) birth cohorts, while these women overtook men in reporting good SRH from the 1975 birth cohort onward. Tertiary educated younger women were significantly less likely to report good SRH than men but parity was achieved at around pension age. Similarly, gender inequality in those with primary and secondary education reduced in the younger ages to not be significant at around age 55, with women overtaking men from age 65. Younger birth cohorts with lower education levels appear most vulnerable in terms of

Body mass deficit at birth is one of the characteristic features observed in Turner's syndrome (TS). Body mass is lower than expected for gestational age in about 90% of TS-babies, and is below -2 SD (i.e. "small for gestational age") in about 20% of patients. The aim of the study was to compare the growth courses of TS-girls born with normal and deficient body mass. A group of 157 TS-girls, delivered at term (> or =38 weeks of gestation), were studied. Body mass of 80 girls ranged from -0.5 to +0.5 SD and body length was above -2 SD (AGA group); another 54 girls had body mass below -2 SD and body length above -2 SD (disproportional SGA group), and 23 girls had both body mass and length below -2 SD (proportional SGA group). Turner's syndrome was confirmed by chromosome analysis. Body mass at birth (BMB) was related to the norms for gestational age (GA) designed by Usher and McLean. Newborns, whose BMB was lower than -2 SD for GA, were considered small for gestational age (SGA). Postnatal body height and mass values were related to Polish norms for females with Turner's syndrome and to the norms for healthy female population. In the spontaneously growing TS-girls from the AGA group, a total of 275 measurements of body mass and height were carried out, the respective numbers for DSGA and PSGA groups were 176 and 100. Mean differences between the actual and expected body height for the AGA, DSGA and PSGA groups amounted to 0.40+/- 1.02, -0.21+/-0.88 and -0.95+/-0.80 SD TS, respectively, all means differing highly significantly (p<0.001) from each other. It may be concluded that spontaneously growing girls with Turner's syndrome, who had a normal (for gestational age) body mass at birth, attain a higher stature than girls with body mass deficit.

Cosmic-ray exposure ages of the ordinary chondrites and their significance for parent body stratigraphy

Improved exposure ages are derived for 201 H, 203 L, and 38 LL chondrites in an effort to understand the characteristics of the chondrite parent body. The Ne-21 exposure ages were calculated from literature values taking into account shielding differences, a trapped component and radiogenic He. The exposure age distributions show clear peaks at 4.5 and 20 million years for the H chondrites, while the Ls and LLs appear more as a continuous series of intermediate peaks which may be modeled by at least six peaks between 1 and 35 million years in the case of L chondrites. The observations that every petrological type occurs in each large peak and contain solar wind gases suggest that the parent bodies have been fragmented and reassembled into a megabreccia. The H meteorites are proposed to represent the surface layer of a body with a substantial, active regolith as indicated by the relatively high abundances of solar gases. The L chondrites, on the other hand, are attributed to a parent body that was fragmented by collision about 500 million years ago.

Nomograms to predict normal aortic root diameter for body surface area (BSA) in broad ranges of age have been widely used but are limited by lack of consideration of gender effects, jumps in upper limits of aortic diameter among age strata, and data from older teenagers. Sinus of Valsalva diameter was measured by American Society of Echocardiography convention in normal-weight, nonhypertensive, nondiabetic subjects ≥15 years old without aortic valve disease from clinical or population-based samples. Analyses of covariance and linear regression with assessment of residuals identified determinants and developed predictive models for normal aortic root diameter. In 1,207 apparently normal subjects ≥15 years old (54% women), aortic root diameter was 2.1 to 4.3 cm. Aortic root diameter was strongly related to BSA and height (r = 0.48 for the 2 comparisons), age (r = 0.36), and male gender (+2.7 mm adjusted for BSA and age, p <0.001 for all comparisons). Multivariable equations using age, gender, and BSA or height predicted aortic diameter strongly (R = 0.674 for the 2 comparisons, p <0.001) with minimal relation of residuals to age or body size: for BSA 2.423 + (age [years] × 0.009) + (BSA [square meters] × 0.461) - (gender [1 = man, 2 = woman] × 0.267), SEE 0.261 cm; for height 1.519 + (age [years] × 0.010) + (height [centimeters] × 0.010) - (gender [1 = man, 2 = woman] × 0.247), SEE 0.215 cm. In conclusion, aortic root diameter is larger in men and increases with body size and age. Regression models incorporating body size, age, and gender are applicable to adolescents and adults without limitations of previous nomograms. Copyright © 2012 Elsevier Inc. All rights reserved.

Body satisfaction is important for the prevention of disordered eating and body image disturbances. Yet, little is known about body esteem and what influences it among younger children. The purpose of this study was to evaluate body esteem and the relationships between body esteem, weight, gender, and physical activity in elementary school children. A total of 214 third graders in a U.S. Midwestern state participated in this correlational study. The Body Mass Index-for-age, the Body Esteem Scale (BES), BE-Weight, BE-Appearance, and a Physical Activity Checklist were used to examine the relationships between the variables using bivariate correlations and analysis of variance. While children's body esteem did not differ by physical activity, important interactions were identified between weight status and gender in global body esteem and BE-Appearance. It is critical to examine attitudes about weight and appearance and the relationship between body esteem and self-esteem further among middle childhood-aged children. Copyright © 2012 Elsevier Ltd.

Fetal body composition is an important determinant of body composition at birth, and it is likely to be an important determinant at later stages in life. The purpose of this work is to provide a comprehensive overview by presenting data from previously published studies that report on body composition during fetal development in newborns and the infant/child through 5 years of age. Understanding the changes in body composition that occur both in utero and during infancy and childhood, and how they may be related, may help inform evidence-based practice during pregnancy and childhood. We describe body composition measurement techniques from the in utero period to 5 years of age, and identify gaps in knowledge to direct future research efforts. Available literature on chemical and cadaver analyses of fetal studies during gestation is presented to show the timing and accretion rates of adipose and lean tissues. Quantitative and qualitative aspects of fetal lean and fat mass accretion could be especially useful in the clinical setting for diagnostic purposes. The practicality of different pediatric body composition measurement methods in the clinical setting is discussed by presenting the assumptions and limitations associated with each method that may assist the clinician in characterizing the health and nutritional status of the fetus, infant and child. It is our hope that this review will help guide future research efforts directed at increasing the understanding of how body composition in early development may be associated with chronic diseases in later life.

To determine whether the lack of private health insurance places children at increased risk for foreign body ingestion or aspiration. Retrospective review. St. Louis Children's Hospital, a tertiary care center. Consecutive sample of 125 patients with esophageal or airway foreign bodies. Fifty percent of all patients had private health insurance. Fifty-six percent of all preschool patients and 20% of all school-age patients were uninsured (P < 0.01, Fisher's exact test). Eighty-five percent of patients with airway foreign bodies, and 84% of patients with esophageal foreign bodies were in the preschool group. Sixty-one percent of preschool patients and 21% of school-age patients with esophageal foreign bodies were uninsured (P < 0.05). Forty-six percent of preschool patients with food aspiration lacked health insurance (88% of these children were fed the aspirated item). No school-age group was available for comparison. Fifty percent of preschool children with aspiration of non food items were uninsured, as were 16% of their school-age counterparts. Insurance status must be considered as a risk factor for foreign body aspiration and ingestion. Preschool children are more likely to lack private health insurance than school-age children with the same diagnosis. In a majority of aspiration events, the child was being fed the inappropriate food item, perhaps indicating a lack of caretaker education and anticipatory guidance. A direct focus on 'passive protection', anticipatory guidance in clinics for all patients, and public education with emphasis on preventive care are proposed as means to decrease the incidence of airway and esophageal foreign bodies in children.

To investigate the suitability of asthma education materials for school-age children with asthma and elucidate how these children used their health-literacy abilities to identify whether the materials can be accepted, comprehended and applied. Effective asthma self-management education is influenced by the suitability of materials and an individual's health literacy. A mixed-method research design was developed using quantitative and qualitative surveys. The suitability of the materials was assessed on the basis of the Chinese version of the Suitability Assessment of Materials by five experts. In addition, five school-age children (age: 8-12 years) were recruited and interviewed. In total, 25 pieces of asthma education material for children were collected. On the basis of their type, the materials were categorised as nine brochures, 11 leaflets and five videos. Of the 25 materials, 17 were rated as superior materials, whereas eight were rated as adequate materials. The suitability scores of the video-based materials were significantly higher than those of the brochures and leaflets (p = .006). One print material was considered to have a reading level suitable for fifth-grade or younger children, whereas the remaining materials were considered suitable for sixth-grade or older children. The following six health-literacy domains were identified: recognising asthma through body knowledge, posing reflective questions, identifying self-care difficulties, receiving adult guidance, learning with enjoyment and addressing learning requirements. The video-based materials had integrated content and were appealing to children. Cartoon animations, interactive computer games, and skill demonstrations may enhance learning stimulation and motivation and increase learning effects in children. The present results may help healthcare providers to understand children's capacities to manage their disease, effectively address children's requirements and function as a key resource for

Age-related variation in morphometry has been documented for many species. Knowledge of growth patterns can be useful for modeling energetics, detecting physiological influences on populations, and predicting age. These benefits have shown value in understanding population dynamics of invasive species, particularly in developing efficient control and eradication programs. However, development and evaluation of descriptive and predictive models is a critical initial step in this process. Accordingly, we used data from necropsies of 1,544 nutria (Myocastor coypus) collected in Maryland, USA, to evaluate the accuracy of previously published models for prediction of nutria age from body weight. Published models underestimated body weights of our animals, especially for ages <3. We used cross-validation procedures to develop and evaluate models for describing nutria growth patterns and for predicting nutria age. We derived models from a randomly selected model-building data set (n = 192-193 M, 217-222 F) and evaluated them with the remaining animals (n = 487-488 M, 642-647 F). We used nonlinear regression to develop Gompertz growth-curve models relating morphometric variables to age. Predicted values of morphometric variables fell within the 95% confidence limits of their true values for most age classes. We also developed predictive models for estimating nutria age from morphometry, using linear regression of log-transformed age on morphometric variables. The evaluation data set corresponded with 95% prediction intervals from the new models. Predictive models for body weight and length provided greater accuracy and less bias than models for foot length and axillary girth. Our growth models accurately described age-related variation in nutria morphometry, and our predictive models provided accurate estimates of ages from morphometry that will be useful for live-captured individuals. Our models offer better accuracy and precision than previously published models

Warming the nursing education climate for traditional-age learners who are male.

Bell-Scriber, Marietta J

2008-01-01

For nurse educators to facilitate student learning and the achievement of desired cognitive, affective, and psychomotor outcomes, they need to be competent in recognizing the influence of gender, experience, and other factors on teaching and learning. A study was conducted in one academic institution to describe how traditional-age male learners' perceptions of the nursing education climate compare to perceptions of female learners. Interviews were conducted with a sample of four male and four female learners. Additional data from interviews with nurse educators, classroom observations, and a review of textbooks provided breadth and depth to their perceptions. Findings support a nursing education climate that is cooler to traditional-age male learners and warmer to traditional-age female learners. The main cooling factor for men was caused by nurse educators' characteristics and unsupportive behaviors. Additional factors inside and outside the education environment contributed to a cooler climate for the male learners. Based on these findings, strategies for nurse educators to warm the education climate for traditional-age male learners are presented.

Body weight status and telomere length in U.S. middle-aged and older adults.

PubMed

An, Ruopeng; Yan, Hai

Telomere length has been proposed as a biomarker of biological aging. This study examined the relationship between body weight status and telomere length in U.S. middle-aged and older adults. Nationally representative data (N=2749) came from the Health and Retirement Study. Linear regressions were performed to examine the relationship between baseline body weight status reported in 1992 and telomere length measured in 2008 in the overall sample and by sex and racial/ethnic groups, adjusted for individual characteristics. Baseline overweight (25kg/m 2 ≤body mass index [BMI]<30kg/m 2 ) and obesity (BMI≥30kg/m 2 ) status positively predicted telomere length 17 years later. Compared with their normal weight counterparts, telomere length ratio was on average 0.062 (95% confidence interval=0.016, 0.109) and 0.125 (0.048, 0.202) larger among overweight and obese adults, respectively. In comparison to women and racial/ethnic minorities, the estimated positive associations between overweight and obesity status and telomere length were more salient among men and non-Hispanic whites, respectively. The positive association between body weight status and telomere length found in this study was opposite to what existing biological model predicts, and could partially relate to the nonlinear relationship between body weight status and telomere length across age cohorts, and/or the lack of reliability of BMI as an indicator for adiposity in the older population. Large-scale longitudinal studies with baseline telomere length measures are warranted to replicate this study finding and explore the potential heterogeneous relationship between body weight status and telomere length.

The objective of this study was to identify independent associations between body composition and bone outcomes, including cortical structure and cortical and trabecular volumetric bone mineral density (vBMD) across the adult age spectrum. This cross-sectional study evaluated over 400 healthy adults (48% male, 44% black race), ages 21-78years. Multivariable linear regression models evaluated associations between whole-body DXA measures of lean body mass index (LBMI) and fat mass index (FMI) and tibia peripheral quantitative CT (pQCT) measures of cortical section modulus, cortical and trabecular vBMD and muscle density (as a measure of intramuscular fat), adjusted for age, sex, and race. All associations reported below were statistically significant (p<0.05). Older age and female sex were associated with lower LBMI and muscle strength. Black race was associated with greater LBMI but lower muscle density. Greater FMI was associated with lower muscle density. Cortical section modulus was positively associated with LBMI and muscle strength and negatively associated with FMI. Adjustment for body composition eliminated the greater section modulus observed in black participants and attenuated the lower section modulus in females. Greater LBMI was associated with lower cortical BMD and greater trabecular BMD. FMI was not associated with either BMD outcome. Greater muscle density was associated with greater trabecular and cortical BMD. Associations between body composition and bone outcomes did not vary by sex (no significant tests for interaction). These data highlight age-, sex- and race-specific differences in body composition, muscle strength and muscle density, and demonstrate discrete associations with bone density and structure. These data also show that age-, sex- and race-related patterns of bone density and strength are independent of differences in body composition. Longitudinal studies are needed to examine the temporal relations between changes in bone and body

Objective: To examine the association between weight changes during early and middle adulthood and the risk of type 2 diabetes mellitus in middle aged and elderly population. Methods: Based on the Guangzhou Biobank Cohort Study (GBCS), 28 736 residents aged ≥50 years were included in Guangzhou. Multivariate logistic regression was used to analyze the association between body weight changes during early or middle adulthood and age when the heaviest weight reaching the threshold on the risk of type 2 diabetes mellitus in middle age or elderly population. Adjustments on age, smoking, alcohol consumption, physical activity, education level, occupation, district of residence and body mass index etc ., were made. Results: The mean age was 64.3 (standard deviation=6.7) years in men and 61.0 (standard deviation=7.0) years in women, with the prevalence rates of diabetes as 13.1% and 13.7% in men and women, respectively. Compared to those with stable body weight, the risk of diabetes increased with weight gain during early and middle adulthood in both men and women (both P values for trend<0.01). Participants who gained more than 20 kg during early and middle adulthood were associated with the highest risk of diabetes in men ( OR =2.83, 95% CI :1.99-4.02) and women ( OR =3.13, 95% CI : 2.47-3.96). Compared to those who reached the highest weight at age 20, those who reaching the highest weight at 40 to 49 years were associated with the highest risk of diabetes, with OR being 5.32 (95% CI : 1.92-14.8) in men and 3.41 (95% CI : 2.49-4.67) in women, respectively. Weight loss in adulthood was associated with self-reported but not newly diagnosed diabetic cases in both middle and older aged men and women. Conclusion: Weight gain during early and middle adulthood may increase the risk of diabetes in middle and older aged population. The detrimental effect of obesity on diabetes might become significantly visible in the next decades.

Pilot educational program to enhance empowering patient education of school-age children with diabetes

2013-01-01

Background Nurses have a crucial role in patient education of children with type 1 diabetes, but they often exhibit lack of knowledge of the patient education process. This study aimed to describe an educational program to enhance empowering patient education process for the blood glucose monitoring education of school-age children and nurses’ perceptions of using empowering techniques. Methods An empowering patient education process for the diabetes education of school-age children was developed. The researcher collected nurse’s perceptions of managing the educational program by semi-structured interviews. Ten nurses carried out the diabetes education, and 8 of them participated in the interview. Three nurses implemented the diabetes education twice and were interviewed twice. The data consisted of 11 descriptions of the blood glucose monitoring education. The interviewer analyzed the data deductively and inductively by content analysis. Results Nurses described successful managing of the empowering patient education process. The need assessment consisted of using multiple methods and clarifying the capabilities and challenges of children and their parents. Planning manifested itself in adequate preparation and multiple objectives stated together with the family. Implementation comprised the relevant content, and the use of suitable teaching materials and methods. Evaluation was performed with various methods and documented accurately. Nurses also faced some challenges related to management and leadership, ambivalence with traditional and empowering patient education, and families’ overall situation. Conclusion An example of developing evidence-based patient education program is presented, but besides education other factors supporting changes in work practices should be considered in further development.

When the relationship between ageing and changes in personality traits is considered, it is important to know how they are influenced by biological and environmental factors. The present study examined the relationships between various factors associated with the effect of ageing on personality traits, including structural changes of the brain and environmental factors such as education. We recruited 41 healthy subjects. We administered the NEO Five-Factor Inventory to assess personality factors. Magnetic resonance imaging was performed, and regional grey matter (GM) volumes were obtained. We identified associations in the correlation analysis of age, cerebral GM volume, years of education, and the personality trait of openness. Path analysis was used to estimate the relationships among these factors. The path analysis model of age, GM volume, years of education, and the personality trait of openness revealed that age has an indirect negative association with openness through GM volume and years of education. Ageing was related to a decrease in GM volume, which was in turn related to a decrease in the openness score. Older subjects generally had fewer years of education, which was related to a lower openness score. Maintaining openness against the effects of ageing is desirable, and our results imply that interventions against age-related cerebral atrophy and the promotion of opportunities for higher education may contribute to the development and stability of a healthy personality during the adult life course. © 2015 The Authors.

2013-12-01

In the present study, a regression analysis of BMI and body fat percentage in each school year was performed with cross-sectional data in school-aged children. The qualitative changes in physique during the school-age years were examined by showing the changes in the level of body fat accu- mulation with age. The subjects were 789 boys and girls (469 boys, 320 girls) aged 7 to 14 years who participated in regular sports activities. Height, weight and body fat percentage were measured. Fat free mass was calculated by subtracting fat mass from body weight. BMI was calculated as body weight (kg) divided by the square of height (m). Regression analysis was conducted for fat percentage against BMI in boys and girls of all school years, and the level of body fat accumulation was considered, the distributions of the frequency of age change were examined. As a result, in the frequency distribution charts there was a shift from excessive fat to low fat from age 7 to 14 years. A χ2 test was then performed for these frequency distribution charts, and the results showed a significant difference in the frequency distribution in each year (P < 0.01). This trend was clearly in boys, and meaning was found in clarifying the changes with age in the body composition balance in boys and girls.

The malleable nature of the self led researchers to investigate the meaning of virtual identity by exploring virtual self-representation through avatars and its association with users' identity. The present study aims to investigate the changes in virtual body-representation in adolescence related to age levels and sex and the association with adolescents' self-esteem and body esteem. Anthropometric features, body esteem and self-esteem were used to assess adolescents' body image and identity. The scoring code of the "Drawing Me" graphical test was used to evaluate the avatars. The sample is composed of 63 adolescents of different ages-early, middle and late adolescence-balanced by sex. Results show that the creation of a digital avatar changes with age and is partially associated with adolescents' perceptions in terms of body esteem and self-esteem. Moreover, the creation of avatars occurs differently for boys, who enrich their avatars with many sexual features, than for girls, who prefer to detail their avatars' clothing to enrich them. Critical reflections and implications for psychological interventions that may use avatars to investigate adolescents' identity in integration with other tools will be discussed.

We conducted a randomized controlled trial of the Aging Well through Interaction and Scientific Education (AgeWISE) program, a 12-week manualized cognitive rehabilitation program designed to provide psychoeducation to older adults about the aging brain, lifestyle factors associated with successful brain aging, and strategies to compensate for age related cognitive decline. Forty-nine cognitively intact participants ≥ 60 years old were randomly assigned to the AgeWISE program (n = 25) or a no-treatment control group (n = 24). Questionnaire data were collected prior to group assignment and post intervention. Two-factor repeated-measures analyses of covariance (ANCOVAs) were used to compare group outcomes. Upon completion, participants in the AgeWISE program reported increases in memory contentment and their sense of control in improving memory; no significant changes were observed in the control group. Surprisingly, participation in the group was not associated with significant changes in knowledge of memory aging, perception of memory ability, or greater use of strategies. The AgeWISE program was successfully implemented and increased participants' memory contentment and their sense of control in improving memory in advancing age. This study supports the use of AgeWISE to improve perspectives on healthy cognitive aging.

Twenty-five year trends in body mass index by education and income in Finland

PubMed Central

2012-01-01

Background The socioeconomic gradient in obesity and overweight is amply documented. However, the contribution of different socioeconomic indicators on trends of body mass index (BMI) over time is less well known. The aim of this study was to investigate the associations of education and income with (BMI) from the late 1970s to the early 2000s. Methods Data were derived from nationwide cross-sectional health behaviour surveys carried out among Finns annually since 1978. This study comprises data from a 25-year period (1978–2002) that included 25 339 men and 25 330 women aged 25–64 years. BMI was based on self-reported weight and height. Education in years was obtained from the questionnaire and household income from the national tax register. In order to improve the comparability of the socioeconomic position measures, education and income were divided into gender-specific tertiles separately for each study year. Linear regression analysis was applied. Results An increase in BMI was observed among men and women in all educational and income groups. In women, education and income were inversely associated with BMI. The magnitudes of the associations fluctuated but stayed statistically significant over time. Among the Finnish men, socioeconomic differences were more complicated. Educational differences were weaker than among the women and income differences varied according to educational level. At the turn of the century, the high income men in the lowest educational group had the highest BMI whereas the income pattern in the highest educational group was the opposite. Conclusion No overall change in the socio-economic differences of BMI was observed in Finland between 1978 and 2002. However, the trends of BMI diverged in sub-groups of the studied population: the most prominent increase in BMI took place in high income men with low education and in low income men with high education. The results encourage further research on the pathways between income

Ability of university-level education to prevent age-related decline in emotional intelligence

2014-01-01

Numerous studies have suggested that educational history, as a proxy measure of active cognitive reserve, protects against age-related cognitive decline and risk of dementia. Whether educational history also protects against age-related decline in emotional intelligence (EI) is unclear. The present study examined ability EI in 310 healthy adults ranging in age from 18 to 76 years using the Mayer–Salovey–Caruso Emotional Intelligence Test (MSCEIT). We found that older people had lower scores than younger people for total EI and for the EI branches of perceiving, facilitating, and understanding emotions, whereas age was not associated with the EI branch of managing emotions. We also found that educational history protects against this age-related EI decline by mediating the relationship between age and EI. In particular, the EI scores of older adults with a university education were higher than those of older adults with primary or secondary education, and similar to those of younger adults of any education level. These findings suggest that the cognitive reserve hypothesis, which states that individual differences in cognitive processes as a function of lifetime intellectual activities explain differential susceptibility to functional impairment in the presence of age-related changes and brain pathology, applies also to EI, and that education can help preserve cognitive-emotional structures during aging.

To identify the most reliable method for age estimation among three variables, that is, condylar height, length of mandibular body and third molar calcification by Demirjian's method. Orthopantomograms and lateral cephalograms of 60 patients with equal gender ratio were included in the study, among each gender 15 subjects were below 18 years and 15 subjects were above 18 years. Lateral cephalograms were traced, height of condyle and mandibular body are measured manually on the tracing paper, OPG's were observed on radiographic illuminator and maturity score of third molar calcification was noted according to Demirjian's method. All the measurements were subjected to statistical analysis. The results obtained are of no significant difference between estimated age and actual age with all three parameters (P > 0.9780 condylar height, P > 0.9515 length of mandibular body, P > 0.8611 third molar calcification). Among these three, length of mandibular body shows least standard error test (i.e. 0.188). Although all three parameters can be used for age estimation, length of mandibular body is more reliable followed by height of condyle and third molar calcification.

To determine if patients with cleft lip and/or palate (CL/P) from a Western Australian (WA) cohort were more dissatisfied with their body esteem than a normative non-cleft cohort, and identify demographic variables that may have significant associations with body esteem. Questionnaire study using the Body-Esteem Scale (BES) and Cleft Research Questionnaire (CRQ). Self-selected participants from a Western Australian CL/P population across 3 age groups (n=359). The BES is comprised of 3 factors: BE-Appearance, BE-Weight and BE-Attribution. Study mean BES factor scores were compared to normative non-cleft scores. Regression analysis was used to determine significant associations within each age group between BES factor scores and CRQ variables of: gender, self-reported body weight category, cleft type and importance of facial appearance rating. Study mean BE-Attribution scores were significantly lower than the normative scores and significantly lower than the mean BE-Appearance and BE-Weight factor scores within the same age groups of this study. Having a cleft type of lip and palate, being overweight, and placing a high importance on facial appearance had significant negative associations with BES scores. Maintaining a normal body weight and placing a lower level of importance on facial appearance had significant positive associations. Gender had no significant associations. In this study, the attribution aspect of body esteem had a greater negative impact on patients than their appearance and body weight. This has important implications for clinical treatment and support of patients.

The aim of the present study was to compare, in 36 highly trained under-15 soccer players, the respective effects of age, maturity and body dimensions on match running performance. Maximal sprinting (MSS) and aerobic speeds were estimated. Match running performance was analysed with GPS (GPSport, 1 Hz) during 19 international friendly games (n = 115 player-files). Total distance and distance covered >16 km h(-1) (D > 16 km h(-1)) were collected. Players advanced in age and/or maturation, or having larger body dimensions presented greater locomotor (Cohen's d for MSS: 0.5-1.0, likely to almost certain) and match running performances (D > 16 km h(-1): 0.2-0.5, possibly to likely) than their younger, less mature and/or smaller teammates. These age-, maturation- and body size-related differences were of larger magnitude for field test measures versus match running performance. Compared with age and body size (unclear to likely), maturation (likely to almost certainly for all match variables) had the greatest impact on match running performance. The magnitude of the relationships between age, maturation and body dimensions and match running performance were position-dependent. Within a single age-group in the present player sample, maturation had a substantial impact on match running performance, especially in attacking players. Coaches may need to consider players' maturity status when assessing their on-field playing performance.

Objectives Aging, body composition, and body mass index (BMI) are important factors in bone mineral density (BMD). Although several studies have investigated the various parameters and factors that differentially influence BMD, the results have been inconsistent. Thus, the primary goal of the present study was to further characterize the relationships of aging, body composition parameters, and BMI with BMD in Chinese Han males older than 50 years. Methods The present study was a retrospective analysis of the body composition, BMI, and BMD of 358 Chinese male outpatients between 50 and 89 years of age that were recruited from our hospital between 2009 and 2011. Qualified subjects were stratified according to age and BMI as follows: 50–59 (n = 35), 60–69 (n = 123), 70–79 (n = 93), and 80–89 (n = 107) years of age and low weight (BMI: < 20 kg/m2; n = 21), medium weight (20 ≤ BMI < 24 kg/m2; n = 118), overweight (24 ≤ BMI < 28 kg/m2; n = 178), and obese (BMI ≥ 28 kg/m2; n = 41). Dual-energy X-ray absorptiometry (DEXA) was used to assess bone mineral content (BMC), lean mass (LM), fat mass (FM), fat-free mass (FFM), lumbar spine (L1-L4) BMD, femoral neck BMD, and total hip BMD. Additionally, the FM index (FMI; FM/height2), LM index (LMI; LM/height2), FFM index (FFMI; [BMC+LM]/height2), percentage of BMC (%BMC; BMC/[BMC+FM+LM] × 100%), percentage of FM (%FM; FM/[BMC+FM+LM] × 100%), and percentage of LM (%LM; LM/(BMC+FM+LM) × 100%) were calculated. Osteopenia or osteoporosis was identified using the criteria and T-score of the World Health Organization. Results Although there were no significant differences in BMI among the age groups, there was a significant decline in height and weight according to age (p < 0.0001 and p = 0.0002, respectively). The LMI and FFMI also declined with age (both p < 0.0001) whereas the FMI exhibited a significant increase that peaked in the 80-89-years group (p = 0.0145). Although the absolute values of BMC and LM declined

This study was done to determine the effects of weight management program using self-efficacy in middle-aged obese women. The study also attempted to measure the effects of the program on the weight efficacy lifestyle, body composition, and depression. The research design of this study was a nonequivalent control group pretest-posttest design. The experimental group consisted of 21 middle-aged obese women and another 21 middle-aged obese women in the control group. The women in the experimental group participated in the weight management program for 12 weeks using self-efficacy. The weight management program using self-efficacy included education on effects of exercise for weight control, aerobic exercise program, muscle training and counseling through the telephone. After 12 weeks of participation in the program, BMI (p<.0001), body fat % (p<.0001), abdominal fat (p<.0001), in the experimental group were significantly decreased compared to the control group. Weight self-efficacy lifestyle (p<.0001) and depression (p=.006) in the experimental group were significantly improved after the program compared to the control group. According to these findings, weight management program self-efficacy for middle-aged obese women could increase weight efficacy lifestyle, and decrease depression, BMI, body fat, and abdominal fat. The result also suggested that the increasing weight efficacy and lifestyle help the obese women to perform and continue exercise. This program could be used in the community such as public health center for weight care and mental health promotion of middle-aged obese women.

The exhibitions of plastinated cadavers and organs have attracted millions of visitors globally, while raising serious controversy about their content and purpose of implementation. We performed a survey based study on 500 randomly chosen individuals, aged 18- to 35-year old, in order to access their opinion regarding the conduction of such shows as well as body donation for scientific purposes. We found that 46.3% of the participants had moral concerns, and 46.1% did not. Religious and philosophical beliefs concerned 21.8% of the sample, while 28% believed that the exhibits may affect visitors' mental health. Human dignity violation was stressed by 21.6%, whereas 26.6% disagreed with body donation to science. The desire for qualitative-guided anatomy education is evident from the highly popular plastinated body and specimen exhibitions. Hence, additional focused effort could be provided to educate the public about normal and pathological anatomy in order to amend their life-style. This could be effected by certified anatomy demonstrators in graduated steps according to the cohort's age, education, occupation, and health status.

Predictors of Self-Rated Health: Does Education Play a Role Above and Beyond Age?

PubMed

Spuling, Svenja M; Huxhold, Oliver; Wurm, Susanne

2017-05-01

Previous studies have demonstrated that while health factors lose importance for the individual conceptualization of self-rated health (SRH) with advancing age, subjective well-being (SWB) factors gain in importance. The present study examined whether this age-related pattern differs between educational groups. Longitudinal data of adults aged 40 years and older of the German Ageing Survey was used (N = 6,812). The role of education in age-related changes in the predictive value of different health and SWB facets for SRH was investigated with a cross-lagged panel regression model. Physical conditions were a stronger predictor in lower than in higher educated individuals while the association did not change with age. In contrast, positive affect and life satisfaction only gained in importance with advancing age for higher educated individuals. Negative affect was an equally strong predictor independent of education, and loneliness had a stronger association with SRH in people with lower education compared to those with high education while the associations did not change with age. The findings highlight the importance of considering the multidimensionality of SWB and the educational background of individuals for the study of SRH and indicate possible limits to adjustment to age-related declines in health. © The Author 2015.

The aim of this study was to analyze the association between area-level education and body mass index (BMI), waist circumference (WC) and obesity controlling for individual demographic and socioeconomic characteristics. A cross-sectional population-based study was carried out with 1720 adults aged 20-59 in southern Brazil. We used multilevel modeling techniques to test whether area-level education was associated with BMI, WC and obesity regardless of individual-level characteristics. We observed a significant between-groups variance for both BMI and WC. Among women, area-level education explained 27.6 and 30.0% of the between-groups variance of BMI and WC, respectively. In the fully adjusted model, the WC was 4.67 cm higher (p < 0.05) and the BMI was 1.12 kg/m(2) higher (p < 0.05) in the women residents of low education neighborhoods compared to the residents of high education areas. In the same group, the chance of central obesity and general obesity was, respectively, 2.05 (IC95% 1.19-3.52) and 1.85 (IC95% 1.04-3.29) times higher. The findings suggest that neighborhood characteristics play an important role in the distribution of obesity and must be addressed by policy makers.

2007-09-01

A cross-sectional study of 183 female Bathudis, a tribal population of the Keonjhar District, Orissa, India, was undertaken to investigate age variations in anthropometric and body composition characteristics and nutritional status. The subjects were categorized into three age groups: < or =30 years, 31-50 years, >50 years. Height, weight, circumferences and skinfolds data were collected. Body mass index (BMI) and several body composition variables and indices were derived using standard equations. The results revealed that there existed significant negative age variations for most of the anthropometric and body composition variables and indices. Correlation studies of age with these variables and indices revealed significant negative correlations. Linear regression analyses revealed that for all variables, age had a significant negative impact. Studies on the nutritional status of these women revealed that with increasing age, there was an increase in the frequency of undernutrition. In conclusion, this study demonstrated that among Bathudi women, age was significantly negatively related with anthropometric and body composition variables and indices. Moreover, with increasing age, the level of undernutrition increased.

Analysis of Lower Body Kinematic and Kinetic: Differences Between Age and Handicap in Golfers of Various Ages and Skill Levels

Smilensky, Alexander

The purpose of this thesis was to provide a preliminary analysis of lower body golf swing biomechanics. Fourteen golfers of various ages and handicaps performed 10 swings off a tee with their driver. This study focused on a number of dependent variables including lead knee joint flexion angles, internal/external rotations, valgus/varus angles, as well as ground reaction forces normalized to body weight (%BW), X-Factor angle and club head velocity. Dependent variables were analyzed at four specifically defined events (start, initiation of downswing, contact and swing termination). Simple linear regressions were performed using age and handicap as independent variables to see if patterns could be determined at any of the events. No significant trends or results were reported within our sample. An analysis of variance (ANOVA) was then used to examine the effect of event on specific dependent variables. A number of differences were reported within each of the variables across the four events. This study hoped to provide a more comprehensive understanding of the movement patterns occurring at the lower body with special focus on the lead knee.

Comparison study for body image education of domestic and overseas female college students

PubMed Central

Kim, Tae-Young

2017-01-01

The 2016 health education index showed such tendency as well including their raised obesity index, and reported that they are much interested in body images appearing externally. Accordingly, in this study, we conducted the self-reported questionnaire aimed at a total of 389 subjects composed of domestic (n= 226) and overseas (n= 163) female college students from Asia, Europe, and Latin America so as to investigate their body images for face, figure and health through questionnaires. In this context, a survey was conducted with the method of this study, consequently indicating that overseas subjects are more greatly positive and active to body images (face, figure, and health) by health level, exercise preferences, extent of body activities and body weight than domestic ones. These results reflect a different viewpoint between those subjects and reveal that overseas subjects are more committed to maintaining their health through body activities compared to domestic ones. Moreover, it is considered that domestic subjects tend to place a higher value on external beauty rather than beauty in terms of physical health, thereby it is most important to change the beauty values. Therefore, in the future, health education should play a critical role in promoting discussions for plans and practical strategies of improving health between students and in participating actively in health behaviours.

Abnormal body proportions may indicate skeletal disorders; therefore, their detection has great clinical significance. To estimate centiles for head circumference/height (HC/H) and sitting height/height (SH/H) ratios, and assess their diagnostic usefulness among a group of children with skeletal dysplasia. Centiles 3, 10, 25, 50, 75, 90 and 97 for HC/H and SH/H ratios were estimated with the LMS method using Box-Cox transformation to normalize data distribution for each age. Q-Q plot tests were applied to evaluate normality of residuals and the Q test to calculate goodness-of-fit. The sample included 4818 girls and4803 boys, all healthy, between 0-17 years old. The median of the SH/H ratio for each age decreased from 0.67 at birth to 0.57 at age 4. At 12 years of age, values reached 0.52 and 0.53 for males and females, respectively, remaining unchanged until age 17. The median of the HC/H ratio decreased from 0.45 at 6 years old to 0.34 at 17 years old for both sexes. Z-scores for SH/H among 20 children diagnosed with hypochondroplasia were better at showing abnormal proportions than the SH/H ratio not adjusted by age. Estimated centiles for HC/H and SH/H ratios show that the most dramatic changes in body proportions occur in the prepubertal period. These references allow an earlier detection of abnormal body proportions in children with skeletal dysplasia.

Objectives To evaluate prospective relationships between body composition and muscle strength with predominantly stress- and urgency urinary incontinence (SUI and UUI) in older women. Design Prospective community-dwelling observational cohort study (Health, Aging, and Body Composition study). Participants Women initially aged 70 to 79 years recruited from Pittsburgh, PA and Memphis, TN. Measurements Urinary incontinence was assessed by structured questionnaires. Body mass index (BMI), grip strength, quadriceps torque and walking speed were assessed by physical examination and performance testing. Appendicular lean body mass (ALM) and whole-body fat mass were measured using dual-energy x-ray absorptiometry. Results Of 1475 women, 212 (14%) and 233 (16%) reported at least monthly predominantly SUI and UUI at baseline, respectively. At 3 years, there were 1137 women, 164 (14%) with new/persistent SUI and 320 (28%) with new/persistent UUI. Women had increased odds of new/persistent SUI if they demonstrated ≥5% decrease in grip strength, (adjusted OR [AOR] 1.60, p=0.047). Alternatively, women had decreased odds of new/persistent SUI if they demonstrated ≥5% decrease in BMI (AOR 0.46; p=0.014), ≥5% increase in ALM corrected for BMI (AOR 0.17; p=0.004), or ≥5% decrease in fat mass (AOR 0.53; p=0.010). Only a ≥5% increase in walking speed was associated with new/persistent UUI over 3 years (AOR 1.54; p=0.040). Conclusion Among women 70 years and older, changes in body composition and grip strength were associated with changes in SUI frequency over time. In contrast, changes in these factors did not influence UUI. Findings suggest that optimization of body composition and muscle strength is more likely to modify SUI than UUI risk among older women.

Little is known about the gender-specific mechanisms through which education is associated with weight status in societies that have experienced a rapid rise in their obesity rates. This study extends previous literature by examining how the link between education and weight status operates within the structure of gender relations in South Korea where huge gender differences have been observed in the educational inequalities in weight status. Using the Korean National Health Survey (N = 17,947) conducted in 2008-2012 conditional quantile regression models were estimated to assess the associations between education and body weight distribution. The mean difference in the predicted probabilities of perceiving body image as average was compared by educational attainment for women and men while setting all other covariates at their means. Highly educated women were more likely to utilize their human capital to obtain slender body shape and the relationship was not mediated by economic resources. In contrast, education was positively associated with being overweight and obesity among men, for whom behaviors promoting healthy weight often conflict with a collective ideology at work that strongly supports long work hours and heavy alcohol consumption. Furthermore, Korean men were more likely to under-perceive their body size than Korean women, that is, overweight men tend to consider themselves to be of 'average' weight, regardless of their educational attainment. Current study found that gender inequalities in social status in South Korea operate to affect the relationship between education and weight status among men and women in unique ways. Weight status can be socially patterned by the interplay between education, economic, and behavioral resources within the structure of gender relations.

Reducing Ageism: Education About Aging and Extended Contact With Older Adults.

Lytle, Ashley; Levy, Sheri R

2017-11-19

Ageism is of increasing concern due to the growing older population worldwide and youth-centered focus of many societies. The current investigation tested the PEACE (Positive Education about Aging and Contact Experiences) model for the first time. Two online experimental studies examined 2 key factors for reducing ageism: education about aging (providing accurate information about aging) and extended contact (knowledge of positive intergenerational contact) as well as their potential combined effect (education plus extended contact). In Study 1, 354 undergraduates in all 3 experimental conditions (vs. control participants) reported less negative attitudes toward older adults (delayed post-test) and greater aging knowledge (immediate and delayed post-tests), when controlling for pre-study attitudes. In Study 2, 505 national community participants (ages 18-59) in all experimental conditions (vs. control participants) reported less negative attitudes toward older adults (immediate post-test) and greater aging knowledge (immediate and delayed post-tests). In summary, across 2 online studies, education about aging and knowledge of intergenerational extended contact improved attitudes toward older adults and aging knowledge. Thus, brief, online ageism-reduction strategies can be an effective way to combat ageism. These strategies hold promise to be tested in other settings, with other samples, and to be elaborated into more in-depth interventions that aim to reduce ageism in everyday culture. © The Author 2017.

The aim of this study was to investigate the relationship between body image, body mass index (BMI), and physical activity in adolescents. The study included 1702 girls and 1547 boys aged 14-16 years. Moderate-to-vigorous physical activity (MVPA) was evaluated by the Physical Activity Screening Measure. Body image was assessed using the Feelings and Attitudes Towards the Body Scale, and participants' BMI was determined based on measured height and weight. Compared to boys, girls reported more negative body image (p<.05). The results of the three-way hierarchical regression revealed that body image was a statistically significant positive predictor of MVPA for adolescents, regardless of BMI. Additionally, body image was a stronger predictor of MVPA in boys than in girls. These findings suggest that body image, rather than BMI, is important in undertaking physical activity in adolescents and should be considered when preparing programs aimed at improving physical activity.

Aged bodies and kinship matters: The ethical field of kidney transplant

PubMed Central

Kaufman, Sharon R.; Russ, Ann J.; Shim, Janet K.

2008-01-01

The number of kidneys transplanted to people over age 70, both from living and cadaver donors, has increased steadily in the past two decades in the United States. Live kidney donation, on the rise for all age groups, opens up new dimensions of intergenerational relationship and medical responsibility when the transfer of organs is from younger to older people. There is little public knowledge or discussion of this phenomenon, in which the site of ethical judgment and activism about longevity and mortality is one’s regard for the body of another and the substance of the body itself is ground for moral consideration about how kinship is “done.” The clinic, patient, and patient’s family together shape a bond between biological identity and human worth, a demand for an old age marked by somatic pliability and renewability, and a claim of responsibility that merges the “right to live” and “making live.” Live kidney transplantation joins genetic, reproductive, and pharmacological forms of social participation as one more technique linking ethics to intervention and the understanding of the arc of human life to clinical opportunity and consumption. Significant in this example is the medicocultural scripting of transplant choice that becomes a high-stakes obligation in which the long-term impacts on generational relations cannot be foreseen.

Aim: To identify the most reliable method for age estimation among three variables, that is, condylar height, length of mandibular body and third molar calcification by Demirjian's method. Materials and Methods: Orthopantomograms and lateral cephalograms of 60 patients with equal gender ratio were included in the study, among each gender 15 subjects were below 18 years and 15 subjects were above 18 years. Lateral cephalograms were traced, height of condyle and mandibular body are measured manually on the tracing paper, OPG's were observed on radiographic illuminator and maturity score of third molar calcification was noted according to Demirjian's method. All the measurements were subjected to statistical analysis. Results: The results obtained are of no significant difference between estimated age and actual age with all three parameters (P > 0.9780 condylar height, P > 0.9515 length of mandibular body, P > 0.8611 third molar calcification). Among these three, length of mandibular body shows least standard error test (i.e. 0.188). Conclusion: Although all three parameters can be used for age estimation, length of mandibular body is more reliable followed by height of condyle and third molar calcification. PMID:26005300

Unhealthy dietary pattern increases the risk of obesity and metabolic disorders in growing children and adolescents. However, the way the habitual pattern of breakfast consumption influences body composition and risk of obesity in adolescents is not well defined. Thus, the aim of the present study was to assess any associations between breakfast consumption practices and body composition profiles in 236 apparently healthy adolescents aged 12 to 19 years. A self-administered questionnaire on dietary behaviour and lifestyle practices and a dietary food frequency questionnaire were used. Body composition and adiposity indices were determined using standard anthropometric measurement protocols and dual energy χ-ray absorptiometry (DXA). Mean age of the participants was 15.3±1.9 years. The majority of participants (71.2%) fell in the normal body mass index (BMI) ranges. Breakfast consumption patterns showed that only half of the participants (50%) were consuming breakfast daily. Gender-specific multivariate analyses (ANCOVA) showed that in both boys and girls, those eating breakfast at least 5 times a week had significantly lower body weight, body mass index (BMI), BMI z-scores, waist circumference, body fat mass and percent body fat (%BF) compared to infrequent breakfast eaters, after adjustment for age, household income, pubertal status, eating-out and snacking practices, daily energy intakes, and daily physical activity levels. The present findings indicate that infrequent breakfast consumption is associated with higher body adiposity and abdominal obesity. Therefore, daily breakfast consumption with healthy food choices should be encouraged in growing children and adolescents to prevent adiposity during these critical years of growth.

To examine the association of self-esteem with the body mass index (BMI), perceived body image (BI), and desired BI of college-age Saudi females. A cross-sectional study was conducted with 907 randomly selected females using a multistage stratified cluster sampling technique. Self-esteem and BI were assessed using the Rosenberg Self-Esteem Scale and Stunkard Figure Rating Scale, respectively. The prevalence of low self-esteem was only 6.1% among college females; however, this percentage was higher (9.8%) among overweight or obese participants. The total self-esteem scores showed significant negative correlations with actual BMI and perceived BI, but not with desired BI. Meanwhile, multivariate analyses revealed significant differences in total self-esteem scores according to obesity/overweight status and perceived BI group, but not desired BI group. Despite the high prevalence of overweight and obesity in Saudi Arabia, few Saudi college females have low self-esteem. In addition, body weight, BMI, perceived BI, and the BMI corresponding to the perceived BI all significantly differed between females with low self-esteem and those with normal self-esteem.

Ageism and Body Esteem: Associations With Psychological Well-Being Among Late Middle-Aged African American and European American Women

PubMed Central

2015-01-01

Objectives. Social expectancy theory posits that cultural values shape how individuals perceive and evaluate others, and this influences how others evaluate themselves. Based on this theory, ageism may shape older individuals’ self-evaluations. Given the cultural focus on beauty and youth, perceptions of age discrimination may be associated with lower body esteem, and this may be associated with poor psychological well-being. Because discrimination has been associated with poor health, and perceptions of health can affect body perceptions, subjective health status may also contribute to lower body esteem. Method. These associations are assessed in a structural equation model for 244 African American and European American women in their early 60s. Results. Perceptions of age discrimination and body esteem were associated with lower psychological well-being for both ethnic groups. Body esteem partially mediated the association between age discrimination and psychological well-being among European American women but not among African American women. Discussion. Age-related discrimination is one source of psychological distress for older adults, though ageism’s associations with body esteem, health, and psychological well-being vary significantly for European American and African American women. Examining body perceptions and health in the contexts of ageism and ethnicity is necessary when considering the psychological well-being of older women. PMID:24013801

The aim of the study was to describe the body composition of Finnish adults, especially by education, and to investigate whether fat-free mass (FFM) can explain educational gradients relating to body mass index (BMI) and waist-to-hip ratio (WHR). Data for this cross-sectional study were based on data collected in 2000-2001 for the Health 2000 Survey. Of the nationally representative sample of 8,028 Finnish men and women aged 30 years and older, 6,300 (78.5%) were included in the study. Body composition measurements were carried out in the health examination, where FFM was assessed with eight-polar bioelectrical impedance analysis. Questions on education were included in the health interview. The mean FFM varied by education in older (>or= 65 y.) men only. In the middle-aged group (30-64 y.), highly educated men were less likely to belong to the lowest quintile of FFM (OR 0.67, 95%CI 0.48-0.93) compared with the least educated subjects. The level of education was inversely associated with the prevalence of high BMI and WHR in middle-aged men. In women, the respective associations were found both in middle-aged women and their older counterparts. Adjustment for FFM slightly strengthened the associations of education with BMI and WHR. The association between education and FFM is weak. Educational gradients of high BMI and high WHR cannot be explained by FFM.

Although birthplace and length of residence have been found to be associated with Body Mass Index (BMI)/obesity in the USA, their effects may not be the same across groups defined by education, gender and race/ethnicity. Using cross-sectional population based data from the 2001 California Health Interview Survey, we investigated the associations of birthplace and US length of residence with BMI, and whether the influence of birthplace-US length of residence on BMI varied by education, gender and race/ethnicity. Our sample included 37,350 adults aged 25-64 years. Self-reported weight and height were used to calculate BMI. Birthplace and length of residence were combined into a single variable divided into five levels: US-born, foreign-born living in the United States for more than 15, 10-14, 5-9, and less than 5 years. Controlling for age, gender, marital status, race/ethnicity, education, income, fruit and vegetable consumption, current smoking and alcohol use, we found that: (1) foreign-born adults had lower BMI than US-born adults; (2) among foreign-born adults, longer residence in the United States was associated with higher BMI; and (3) the effect of birthplace-length of US residence on BMI differed by education level, gender and race/ethnicity. Specifically, longer residence in the United States was associated with the greatest percent increases in BMI among the lowest educated groups than higher educated groups, among women (vs. men) and among Hispanics (vs. other racial/ethnic groups). These findings suggest that a protective effect of foreign birthplace on BMI appears to attenuate with length of residence in the United States, and also reveal that BMI/obesity trajectories associated with length of US residence vary by education, gender and race/ethnicity. Immigrant status, independently and in combination with education, gender and race/ethnicity should be considered in future obesity prevention and reduction efforts.

Anthropometrics and body mass index are only proxies in the evaluation of adiposity in the pediatric population. Air displacement plethysmography technology was not available for children aged 6 months to 9 years until recently. Our study was designed to test the precision of air displacement plethysmography (ADP) in measuring body fat mass in children at ages 3 to 5 years compared with a criterion method, deuterium oxide dilution (D(2)O), which estimates total body water and a commonly used methodology, dual-energy x-ray absorptiometry (DXA). A prospective, cross-sectional cohort of 66 healthy children (35 girls) was recruited in the central Arkansas region between 2007 and 2009. Weight and height were obtained using standardized procedures. Fat mass (%) was measured using ADP, DXA, and D(2)O. Concordance correlation coefficient and Bland-Altman plots were used to investigate the precision of the ADP techniques against D(2)O and DXA in children at ages 3 to 5 years. ADP concordance correlation coefficient for fat mass was weak (0.179) when compared with D(2)O. Bland-Altman plots revealed a low accuracy and large scatter of ADP fat mass (%) results (mean=-2.5, 95% CI -20.3 to 15.4) compared with D(2)O. DXA fat mass (%) results were more consistent although DXA systematically overestimated fat mass by 4% to 5% compared with D(2)O. Compared with D(2)O, ADP does not accurately assess percent fat mass in children aged 3 to 5 years. Thus, D(2)O, DXA, or quantitative nuclear magnetic resonance may be considered better options for assessing fat mass in young children. Copyright © 2012 Academy of Nutrition and Dietetics.

Dietary sugars have been shown to promote excess adiposity among children and adults; however, no study has examined fructose in human milk and its effects on body composition during infancy. Twenty-five mother-infant dyads attended clinical visits to the Oklahoma Health Sciences Center at 1 and 6 months of infant age. Infants were exclusively breastfed for 6 months and sugars in breast milk (i.e., fructose, glucose, lactose) were measured by Liquid chromatography-mass spectrometry (LC-MS/MS) and glucose oxidase. Infant body composition was assessed using dual-energy X-ray absorptiometry at 1 and 6 months. Multiple linear regression was used to examine associations between breast milk sugars and infant body composition at 6 months of age. Fructose, glucose, and lactose were present in breast milk and stable across visits (means = 6.7 μg/mL, 255.2 μg/mL, and 7.6 g/dL, respectively). Despite its very low concentration, fructose was the only sugar significantly associated with infant body composition. A 1-μg/mL higher breast milk fructose was associated with a 257 g higher body weight ( p = 0.02), 170 g higher lean mass ( p = 0.01), 131 g higher fat mass ( p = 0.05), and 5 g higher bone mineral content ( p = 0.03). In conclusion, fructose is detectable in human breast milk and is positively associated with all components of body composition at 6 months of age.

More depressive symptoms and low emotional support have been related to worse body composition. Body composition significantly deteriorates in aging men. Therefore, we aimed to examine whether high emotional support and low depressive symptoms are associated with better body composition and a decelerated age-related deterioration of body composition in aging men. A cross-sectional analysis including 269 self-reporting healthy men aged between 40 and 75 years living in the German-speaking part of Switzerland was conducted. Participants completed questionnaires on emotional support and depressive symptoms. The depression screening instrument was used to form a group with low (N = 225) and moderate (N = 44) depressive symptoms. Body mass index (BMI) and waist-to-hip ratio (WHR) were measured, and cell proportion (CP), fat mass (FM), and water balance (WB) were obtained using bioelectrical impedance analysis. Age-related associations emerged for WHR, CP, FM, and WB, but not for BMI. Emotional support was negatively associated with BMI, WHR, and WB, and only trend-wise with CP and FM. Group comparisons revealed that more depressive symptoms were associated with lower levels of CP and higher levels of WB. Both emotional support and depressive symptoms were significant moderators of the association between age and specific measures of body composition such as CP, FM, and WB. However, after correction for multiple testing for moderation analyses only the moderation effects of depressive symptoms on the association between age and WB and CP remained significant. Low depressive symptoms were associated with a better body composition as well as a decelerated decline in body composition and the role of emotional support acting as a buffer against age-related deterioration of body composition merits further investigation.

To develop age- and sex-specific centile reference curves for fat-free mass (FFM) and fat mass (FM) adjusted for height in an adult Kenyan population and to investigate the association between FM, FFM and blood pressure (BP). Measures of body composition from bioimpedance analyses and BP were collected in 1995 participants aged ≥50 years in Nakuru County, Kenya. Reference curves were produced using the LMS method. Multivariable linear regression models were used to test the cross-sectional association between body composition indexes and BP. The age- and sex-specific reference curves for body composition (FMI and FFMI) confirmed that FFMI is lower in both men and women with increasing age. FMI declines with age in women while among men the decline starts after 70 years. FFM was higher in men (47.4 ± 7.2 kg) than in women (38.8 ± 5.5 kg), while FM was lower in men (17.3 ± 8.1 kg) than in women (24.4 ± 10.2 kg). FMI, FFMI and BMI were all positively associated with systolic and diastolic BP, and after adjusting for body weight, FFMI remained positively associated with systolic BP and the FMI remained positively associated with diastolic BP. There was no evidence to suggest that FMI and FFMI were superior to measurement of BMI alone. These body composition reference curves provide normative data on body composition for older adults in Kenya. Further research should consider the prospective associations with health, including frailty-related outcomes.

In the human body, the relation between fat and fat-free mass (muscles, bones etc.) is necessary for the diagnosis of obesity and prediction of its comorbidities. Numerous formulas, such as Deurenberg et al., Gallagher et al., Jackson and Pollock, Jackson et al. etc., are available to predict body fat percentage (BF%) from gender (GEN), age (AGE) and body mass index (BMI). These formulas are all fairly similar and widely applicable, since they provide an easy, low-cost and non-invasive prediction of BF%. This paper presents a program solution for predicting BF% based on artificial neural network (ANN). ANN training, validation and testing are done by randomly divided dataset that includes 2755 subjects: 1332 women (GEN = 0) and 1423 men (GEN = 1), with AGE from 18 to 88 y and BMI from 16.60 to 64.60 kg/m(2). BF% was estimated by using Tanita bioelectrical impedance measurements (Tanita Corporation, Tokyo, Japan). ANN inputs are: GEN, AGE and BMI, and output is BF%. The predictive accuracy of our solution is 80.43%. The main goal of this paper is to promote a new approach to predicting BF% that has same complexity and costs but higher predictive accuracy than above-mentioned formulas.

The aim of this study was to investigate the GH-IGF-I axis in healthy adults and its relationship to obesity. We studied 268 subjects: 134 men and 134 women, and determined anthropometric and body composition variables. Serum total IGF-I was measured by radioimmunoassay, serum free IGF-I concentrations by enzyme linked immunosorbant assay and serum IGFBP3 concentrations by radioimmunoassay. In men, we observed a decrease in total IGF-I, free IGF-I and IGFBP-3 throughout decades. In women, the body mass index and fat mass were higher throughout decades, and we observed a similar decrease to that in men in total IGF-I, free IGF-I and IGFBP3. In men with obesity, as measured by body fat, free IGF-I concentrations were lower than those without obesity; in women with obesity, total IGF-I concentrations and free IGF-I concentrations were lower than in those with obesity. These changes were observed in relationship to obesity when the subjects were adjusted for differences in age. We showed that in controls randomly selected, the GH-IGF-I axis component concentrations that decrease with increasing age are lower in obesity, especially in women, and that this decrease is related to body mass index and body fat.

Effects of age, education, and sex on response bias in a recognition task.

This study examined age-related differences in decision criteria and the extent to which inconsistencies in earlier findings could be due to sampling artifacts, especially the underlying effects of educational level and sex. Male and female participants (N = 3,059) from 4 age groups (32, 42, 52, and 62 years) and a wide range of educational levels performed a word recognition task. Response bias was assessed with a nonparametric index derived from signal detection theory. The analyses revealed no age differences except for the most educated subjects, for whom increased age was associated with stricter decision criteria. Lower levels of education and men as compared with women were associated with a more conservative bias. Controlling for the level of sensitivity did not significantly change this pattern of results. This finding stresses the need for caution in generalizing age differences obtained from samples that are only partly representative or imbalanced with respect to education and sex.

Inter-subject variability in age-related brain changes may relate to educational attainment, as suggested by cognitive reserve theories. This voxel-based morphometry study investigated the impact of very low educational level on the relationship between regional gray matter (rGM) volumes and age in healthy elders. Magnetic resonance imaging data were acquired in elders with low educational attainment (less than 4 years) (n = 122) and high educational level (n = 66), pulling together individuals examined using either of three MRI scanners/acquisition protocols. Voxelwise group comparisons showed no rGM differences (p<0.05, family-wise error corrected for multiple comparisons). When within-group voxelwise patterns of linear correlation were compared between high and low education groups, there was one cluster of greater rGM loss with aging in low versus high education elders in the left anterior cingulate cortex (p<0.05, FWE-corrected), as well as a trend in the left dorsomedial prefrontal cortex (p<0.10). These results provide preliminary indication that education might exert subtle protective effects against age-related brain changes in healthy subjects. The anterior cingulate cortex, critical to inhibitory control processes, may be particularly sensitive to such effects, possibly given its involvement in cognitive stimulating activities at school or later throughout life.

To compare the prediction of cognitive functioning by formal education and self-rated literacy and the differences in prediction across younger and older cohorts. Data on 28,535 respondents were drawn from a cross-sectional representative sample of community-dwelling older individuals (≥50), participating in the Survey of Health, Ageing, and Retirement in Europe. Education level was classified according to the International Standard Classification of Education 1997 (ISCED-1997) self-rated literacy was determined by having respondents rate their reading and writing on 1-5 scales. Cognitive functioning was measured by verbal recall, word fluency, and arithmetic ability. Structural equation modeling demonstrated that self-rated literacy was more strongly associated with cognitive functioning than was education level, with or without additional exogenous variables (age, sex, household income, medical conditions, activities of daily living, reading eyesight, and country). The association between education level and cognitive functioning was weaker in older than in younger age groups, whereas the association between self-rated literacy and cognitive functioning showed the opposite trend. Self-rated literacy was found to be a better predictor of late-life cognitive functioning than was the level of formal education. The results have implications for studies of age-related differences in which education level is taken into account.

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.

The kinematics of children's walking are nearly adult-like by about age 3-4 years, but metabolic efficiency of walking does not reach adult values until late in adolescence or early adulthood, perhaps due to higher coactivation of agonist/antagonist muscle pairs in adolescents. Additionally, it is unknown how use of a body weight-supported treadmill device affects coactivation, but because unloading will alter the activity of anti-gravity muscles, it was hypothesized that muscle coactivation will be altered as well. Muscle coactivation during treadmill walking was evaluated for adolescents (ages 10 to 17 years, M = 13.2, SD = 2.2) and adults (ages 22 to 35 years, M = 25.2, SD = 4.3), for thigh muscles (vastus lateralis/biceps femoris) and lower leg muscles (tibialis anterior/gastrocnemius). Conditions included body weight unloadings from nearly 0% to 80% of body weight, while walking at a preferred speed (self-selected, overground speed) or a reduced speed. Unloading was accomplished using a lower body positive pressure support system. Coactivation was found to be higher in adolescents than in adults, but only for the lower leg muscles.

Until a century ago, Korean medicine was based mainly on Oriental philosophies and ideas. From a religious perspective, Chinese Confucianism was prevalent in Korea at that time. Since Confucianists believe that it is against one's filial duty to harm his or her body, given to them by their parents, most Koreans did not donate their bodies or organs for education in the past. However, by the end of the 20th century, a unique fusion of Western and Oriental medicines were produced on the Korean Peninsula, revolutionizing traditional perspectives on the human body, mortality, and the relationship of medical science to society. Koreans began to think about others' lives as well as their own by realizing the importance of donating one's organs and bodies for scientific purposes. Since then, the number of people donating their bodies to Korean medical and dental schools for the purpose of improving academic learning has increased dramatically. In response, Korean medical schools have begun to hold various types of funeral ceremonies to honor body donors. We have compared such ceremonies performed in Korea with those performed in the United States of America and Taiwan. These ceremonies are viewed as a suitable way to pay proper respect to the dead and to promote knowledge about body donation programs in Korea. Overall, the transition of religions and social ethics in Korea has greatly facilitated body bequeathal programs, benefiting both medical education and the Korean public health administration.

Background This study examines the underlying characteristics of adolescents attending Italian secondary school who expressed indifference towards or no interest at all in body art. Methods A convenience sample of 4,277 secondary school students from the North Eastern Italy were surveyed with a self-reported questionnaire collecting extensive socio-demographic information. Multivariable logistic regression analysis was employed to investigate the characteristics of those who were not interested or indifferent towards piercing and tattoo, reporting adjusted Odds Ratios (aOR) with a 95% confidence interval (CI). Results Prevalence of tattoo was 6%, whereas body piercing was 20%; 66% (= 558/840) of those with a piercing were underage (<18 years of age), the equivalent for tattoo being 62% (= 159/258). 166 individuals reported having both piercing and tattoo and 152 of these (92% = 152/166) were <18 years of age. The factors found to be predominately higher in those indifferent or who did not indicate interest in body art were: higher school year, increasing father's education and a greater perception of the associated health risks. Discussion Proactive health education campaigns by school educators and family physicians should focus on adolescents of less educated fathers and pupils less aware of the health risks associated with body art. In this respect junior secondary school students can be regarded as the ideal target of such campaigns. PMID:20942946

Objective: To understand the overweight rate and obesity rate in middle-aged and elderly people in urban area of Beijing, and analyze the changes of body composition and resting metabolic rate with age. Methods: From November 2014 to December 2015, body composition measurement and resting metabolic rate detection were conducted among 858 people aged 51 to 99 years, including 760 men, 98 women, who received physical examination at Beijing Hospital. Results: The overweight rate was 51.4 % , and the obesity rate was 16.9 % . The overweight rate was 26.5 % and the obesity rate was 14.3 % in women, significantly lower than those in men (54.6 % and 17.2 % ) ( P <0.001). The distribution of skeletal muscle volume, muscle index, body fat percentage, visceral fat area and resting metabolic rate in different age groups were different ( P <0.001). In the normal weight group, the skeletal muscle volume, muscle index and resting metabolic rate in age group ≥80 years decreased obviously ( P <0.05). At the same time, the body fat percentage and visceral fat area increased obviously ( P <0.05). However, the skeletal muscle volume, muscle index and resting metabolic rate of the overweight and obese groups began to decrease obviously in age group 70- years ( P <0.05), and the decrease in age group ≥80 years was more obvious. At the same time, body fat percentage and visceral fat area increased significantly in age group 70- years ( P <0.05). Conclusion: The overweight and obesity rates were high in the middle-aged and elderly people in the urban area of Beijing, and the rates were higher in men than in women. With the increase of age, the skeletal muscle volume, muscle index and resting metabolic rate gradually decreased, while the percentage of body fat and visceral fat area increased; Overweight and obese people had earlier changes in body composition and resting metabolic rate.

The aims of the study were to develop sex- and age-specific percentiles for lean mass index (LMI), appendicular LMI (aLMI), fat mass index (FMI), and body fat distribution indices in Chinese adults using dual-energy X-ray absorptiometry (DXA), and to compare those indices with those of other ethnicities using the US NHANES data. Whole-body and regional lean mass and fat mass (FM) were measured using DXA in 5688 healthy males (n = 1693) and females (n = 3995) aged 20-90 years. Body fat distribution indices were expressed as % fat trunk/% fat legs, trunk/appendicular FM ratio (FMR), and android/gynoid FMR. Percentile curves of LMI, aLMI, FMI, and body fat distribution indices were obtained by the Lambda-Mu-Sigma method. The aLMI and LMI were negatively associated with age, decreasing from the fifth decade for males, but were not associated with age in females. Females had more total FM than males, whereas males had greater central adiposity (% fat trunk/% fat legs ratio, trunk/appendicular FMR, and android/gynoid FMR) than females. Moreover, FMI and body fat distribution indices consistently increased with age in both sexes, especially in women. In comparison with white, black, and Mexican populations in the USA, Chinese adults had lower total FM, but had greater central adiposity (% fat trunk/% fat legs ratio and trunk/appendicular FMR). Additionally, older white and Mexican populations showed greater decreases for aLMI and LMI than their Chinese counterparts. We present the sex- and age-specific percentiles for aLMI, LMI, FMI, and body fat distribution indices by DXA in Chinese adults, which may refine the individual assessment of the nutritional status of Chinese adults.

Influence of Resistance Exercise on Lean Body Mass in Aging Adults: A Meta-Analysis

Purpose Sarcopenia plays a principal role in the pathogenesis of frailty and functional impairment that occurs with aging. There are few published accounts which examine the overall benefit of resistance exercise (RE) for lean body mass (LBM), while considering a continuum of dosage schemes and/or age ranges. Therefore the purpose of this meta-analysis was to determine the effects of RE on LBM in older men and women, while taking these factors into consideration. Methods This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations. Randomized controlled trials and randomized or non-randomized studies among adults ≥ 50 years, were included. Heterogeneity between studies was assessed using the Cochran Q and I2 statistics, and publication bias was evaluated through physical inspection of funnel plots as well as formal rank-correlation statistics. Mixed-effects meta-regression was incorporated to assess the relationship between RE dosage and changes in LBM. Results Data from forty-nine studies, representing a total of 1328 participants were pooled using random-effect models. Results demonstrated a positive effect for lean body mass and there was no evidence of publication bias. The Cochran Q statistic for heterogeneity was 497.8, which was significant (p < 0.01). Likewise, I2 was equal to 84%, representing rejection of the null hypothesis of homogeneity. The weighted pooled estimate of mean lean body mass change was 1.1 kg (95% CI, 0.9 kg to 1.2 kg). Meta-regression revealed that higher volume interventions were associated (β = 0.05, p < 0.01) with significantly greater increases in lean body mass, whereas older individuals experienced less increase (β = -0.03, p = 0.01). Conclusions RE is effective for eliciting gains in lean body mass among aging adults, particularly with higher volume programs. Findings suggest that RE participation earlier in life may provide superior effectiveness. PMID:20543750

To determine the association between family structure, maternal education level, and maternal employment with sedentary lifestyle in primary school-age children. Data were obtained from 897 children aged 6 to 12 years. A questionnaire was used to collect information. Body mass index (BMI) was determined using the age- and gender-specific Centers for Disease Control and Prevention definition. Children were categorized as: normal weight (5(th) percentile≤BMI<85(th) percentile), at risk for overweight (85(th)≤BMI<95(th) percentile), overweight (≥ 95(th) percentile). For the analysis, overweight was defined as BMI at or above the 85(th) percentile for each gender. Adjusted odds ratios (adjusted ORs) for physical inactivity were determined using a logistic regression model. The prevalence of overweight was 40.7%, and of sedentary lifestyle, 57.2%. The percentage of non-intact families was 23.5%. Approximately 48.7% of the mothers had a non-acceptable educational level, and 38.8% of the mothers worked outside of the home. The logistic regression model showed that living in a non-intact family household (adjusted OR=1.67; 95% CI=1.04-2.66) is associated with sedentary lifestyle in overweight children. In the group of normal weight children, logistic regression analysis show that living in a non-intact family, having a mother with a non-acceptable education level, and having a mother who works outside of the home were not associated with sedentary lifestyle. Living in a non-intact family, more than low maternal educational level and having a working mother, appears to be associated with sedentary lifestyle in overweight primary school-age children.

Quinn, Cristina L.

2012-01-01

Background: Body burdens of persistent bioaccumulative contaminants estimated from the cross-sectional biomonitoring of human populations are often plotted against age. Such relationships have previously been assumed to reflect the role of age in bioaccumulation. Objectives: We used a mechanistic modeling approach to reproduce concentration-versus-age relationships and investigate factors that influence them. Method: CoZMoMAN is an environmental fate and human food chain bioaccumulation model that estimates time trends in human body burdens in response to time-variant environmental emissions. Trends of polychlorinated biphenyl (PCB) congener 153 concentrations versus age for population cross sections were estimated using simulated longitudinal data for individual women born at different times. The model was also used to probe the influence of partitioning and degradation properties, length of emissions, and model assumptions regarding lipid content and liver metabolism on concentration–age trends of bioaccumulative and persistent contaminants. Results: Body burden–age relationships for population cross sections and individuals over time are not equivalent. The time lapse between the peak in emissions and sample collection for biomonitoring is the most influential factor controlling the shape of concentration–age trends for chemicals with human metabolic half-lives longer than 1 year. Differences in observed concentration–age trends for PCBs and polybrominated diphenyl ethers are consistent with differences in emission time trends and human metabolic half-lives. Conclusions: Bioaccumulation does not monotonically increase with age. Our model suggests that the main predictors of cross-sectional body burden trends with age are the amount of time elapsed after peak emissions and the human metabolic and environmental degradation rates.

Objective To describe national trends in discretionary calories from sugar sweetened beverage (SSB) and snacks by age-specific body weight categories and by age- and weight-specific race/ethnicity groups. Examining these sub-populations is important as population averages may mask important differences. Design and Methods We used 24-hour dietary recall data obtained from the National Health and Nutrition Examination Survey 2003–2010 among children aged 2 to 19 (N=14,092). Logistic and linear regression methods were used to adjust for multiple covariates and survey design. Results The number of calories from SSBs declined significantly for nearly all age-specific body weight groups. Among overweight or obese children, significant declines in the number of calories from SSBs were observed among Hispanic children aged 2 to 5 (117 kcal vs. 174 kcal) and white adolescents aged 12 to 19 (299 kcal vs. 365 kcal). Significant declines in the number of calories from salty snacks were observed among white children aged 2 to 5 (192 kcal to 134 kcal) and 6 to 11 (273 kcal vs. 200 kcal). Conclusions The decrease in SSB consumption and increase in snack consumption observed in prior research are not uniform when children are examined within sub-groups accounting for age, weight and race/ethnicity.

Background Loss of muscle strength exerts a considerable impact on the quality of life and mortality of older adults. The present household survey study measured body composition and muscle strength with the aim of analyzing the roles of low lean mass, low muscle strength and obesity in stair negotiation ability and the effect of comorbidities on the relationship between body composition and functional capacity. Methods Body composition was assessed using bioelectrical impedance analysis and muscle strength was assessed with a hand grip dynamometer. The study population comprised individuals >55 years of age from a medium-sized Brazilian municipality. The sample included 451 participants. Results A total of 368 subjects were interviewed; their ages varied from 56 to 91 years. Among males, low muscle strength was associated with stair negotiation difficulty independent of muscle mass, age and obesity but muscle mass was not. However, when we analyzed comorbidities and body composition jointly, chronic lower limb pain and obesity were independently associated with stair negotiation difficulty but body composition and age were not. Among women, after comorbidities were included into the model, low muscle strength and obesity remained associated with stair negotiation difficulty as chronic lower limb pain and depression. The relationship between muscle function and comorbidities is discussed in this article. PMID:28860730

To correlate different methods of body composition assessment in overweight or obese schoolchildren, using deuterium oxide (D2O) dilution as a reference. Percentage of total body water (%TBW), fat free mass (%FFM), and body fat (%BF) were assessed by D2O and tetrapolar electrical bioimpedance analysis (BIA) in 54 obese and overweight students aged 6-9 years. Skinfold thickness (ST), body mass index (BMI), conicity index (CI), waist circumference (WC), waist-to-height ratio (WHtR), and waist-to-hip (WHR) ratio were also used. Mean values for body composition were 38.4%±8.4% BF, 44.9%±6.1% TBW and 61.6%±8.4% FFM. There was no significant difference in body weight, body fat mass (FM), TBW, and FFM between genders. Regarding D2O, ST underestimated %BF, and overestimated %FFM in both genders (p<0.05). BIA overestimated %TBW in the group as a whole and in males (p<0.05). The only positive and strong correlations occurred in females regarding the WC (σ=0.679), CI (r=0.634), and WHtR (r=0.666). In this sample of obese and overweight children, there were strong correlations between body composition measured by D2O and some indices and anthropometric indicators in females, but there was no positive and strong correlation of fat tissue with the indices/indicators at all ages and in both genders.

Goh, Victor H-H; Tong, Terry Y Y

The present study sought to examine the association between physical exercise as a lifestyle habit with anthropometric parameters and body composition and aging in men. Intensity of exercise was scored as metabolic equivalent-min/week (MET-min/week) from data of the questionnaire, while anthropometric parameters and body composition were carried out by standard measuring instruments and dual-energy X-ray absorptiometry scanner, respectively. Age was associated with decreases in bodyweight, height, total lean mass and bone mass, but an increase in fat mass. The negative association of lean mass with age was predominantly due to the negative association of lean masses in the legs and arm, while the positive association of fat mass with age was primarily due to the positive association of fat masses in the trunk and abdomen. Exercise of intensity greater than 1000 MET-min/week was significantly associated with higher lean and bone masses and lower fat mass. The increase in lean mass was predominantly in the legs, while the decreases in fat mass were in the trunk and abdomen. The study showed that the high intensity of physical exercise, equivalent to greater than 1000 MET-min/week, is required to effect beneficial changes in the body composition. Hence, results from the study support the importance of promoting a lifestyle habit of exercise of sufficient intensity in order to mitigate the increase risks of sarcopenia and obesity and their attendant ill effects on health in men as they age.

Introduction The development of overweight is often measured with the body mass index (BMI). During childhood the BMI curve has two characteristic points: the adiposity rebound at 6 years and the BMI peak at 9 months of age. In this study, the associations between the BMI peak and body composition measures and blood pressure at age 5–6 years were investigated. Methods Measurements from the Amsterdam Born Children and their Development (ABCD) study were available for this study. Blood pressure (systolic and diastolic) and body composition measures (BMI, waist-to-height ratio, fat percentage) were gathered during a health check at about 6 years of age (n = 2822). All children had multiple BMI measurements between the 0–4 years of age. For boys and girls separately, child-specific BMI peaks were extracted from mixed effect models. Associations between the estimated BMI peak and the health check measurements were analysed with linear models. In addition, we investigated the potential use of the BMI at 9 months as a surrogate measure for the magnitude of the BMI peak. Results After correction for the confounding effect of fetal growth, both timing and magnitude of the BMI peak were significantly and positively associated (p<0.001) with all body composition measures at the age of 5–6 years. The BMI peak showed no direct association with blood pressure at the age 5–6 year, but was mediated by the current BMI. The correlation between the magnitude of the BMI peak and BMI at 9 months was approximately 0.93 and similar associations with the measures at 5–6 years were found. Conclusion The magnitude of the BMI peak was associated with body composition measures at 5–6 years of age. Moreover, the BMI at 9 months could be used as surrogate measure for the magnitude of the BMI peak. PMID:24324605

The aims of the current study were to (1) determine the association between personal income and body mass index (BMI) and between individual education and BMI, and (2) examine the association between education and BMI across strata of personal income among women. The design of the study was a quantitative analysis of data from self-report questionnaires. The study setting was socioeconomically disadvantaged neighborhoods in Victoria, Australia. The study included 4065 nonpregnant women (ages 18-45 years) living in socioeconomically disadvantaged areas. The study used a self-report questionnaire measuring sociodemographic characteristics known to be associated with BMI. Multiple linear regressions with imputation were used to assess the association between education level, personal income, and BMI, while controlling for covariates. Mean (SD) observed BMI was 26.0 (6.1) kg/m2. Compared with women with low education, women with medium (b = -0.81; 95% confidence interval, -1.30 to -0.27; p = .004) and high (b = -1.71; 95% confidence interval, -2.34 to -1.09; p < .001) education had statistically significantly lower BMI values. No differences in BMI were observed between income categories. Stratified analyses suggested that the education-BMI association may be stronger in low-income than higher-income women. Our data show that among women living in socioeconomically disadvantaged areas, high education level rather than personal income may be protective against overweight/obesity. High personal income, however, may buffer the effects of low education on BMI. Obesity prevention efforts should target women with amplified disadvantage.

BACKGROUND The impacts of shifts in the age distribution of the working-age population have been studied in relation to the effect of the baby boom generation on the earnings of different cohorts in the U.S. However, this topic has received little attention in the context of the countries of Asia and Latin America, which are now experiencing substantial shifts in their age-education distributions. OBJECTIVE In this analysis, we estimate the impact of the changing relative size of the adult male population, classified by age and education groups, on the earnings of employed men living in 502 Brazilian local labor markets during four time periods between 1970 and 2000. METHODS Taking advantage of the huge variation across Brazilian local labor markets and demographic census micro-data, we used fixed effects models to demonstrate that age education group size depresses earnings. RESULTS These effects are more detrimental among age-education groups with higher education, but they are becoming less negative over time. The decrease in the share of workers with the lowest level of education has not led to gains in the earnings of these workers in recent years. CONCLUSIONS These trends might be a consequence of technological shifts and increasing demand for labor with either education or experience. Compositional shifts are influential, which suggests that this approach could prove useful in studying this central problem in economic development. PMID:26146484

The cognitive processes underlying age-related alterations in tests assumed to reflect frontal lobe functions were investigated with a card sorting test and an alternate semantic fluency task. The tests were administered to 133 healthy women belonging to 3 age groups (range=50-92 years) classed according to 2 education levels. The results revealed a negative association between total word fluency and perseveration in the sorting test. Aging similarly affected performance in both education groups in some components of the tasks (atypical word fluency and sensitivity to distraction). However, aging did not affect performance to the same extent in each education group in other components (particularly those reflecting switching abilities and strategies). This quasi-experimental approach provides useful tools to identify specific processing mechanisms underlying executive functions in normal aging. Copyright (c) 2005 APA, all rights reserved.

To assess body shape ideals across gender, sexual orientation, race, socio-economic status, and age, An analysis of personal advertisements was conducted across seven different publications which targeted the groups of interest. Women advertised body weight much less often than men, and lesbians reported body shape descriptors significantly less often than heterosexual women. Gay men and African-American men described their body shape significantly more often than did other groups. However, their reported body mass indices (BMI) were significantly different-African-American men reported a higher BMI, and gay men a lower BMI, than Euro-American heterosexual men. Race and sexual orientation may influence the importance of size of body shape ideals for men. For women, however, their advertised weights conformed to the thin ideal across all groups surveyed. Gender roles affecting body shape ideals and mate attraction are discussed.

Objectives. To compare the prediction of cognitive functioning by formal education and self-rated literacy and the differences in prediction across younger and older cohorts. Method. Data on 28,535 respondents were drawn from a cross-sectional representative sample of community-dwelling older individuals (≥50), participating in the Survey of Health, Ageing, and Retirement in Europe. Education level was classified according to the International Standard Classification of Education 1997 (ISCED-1997) self-rated literacy was determined by having respondents rate their reading and writing on 1–5 scales. Cognitive functioning was measured by verbal recall, word fluency, and arithmetic ability. Results. Structural equation modeling demonstrated that self-rated literacy was more strongly associated with cognitive functioning than was education level, with or without additional exogenous variables (age, sex, household income, medical conditions, activities of daily living, reading eyesight, and country). The association between education level and cognitive functioning was weaker in older than in younger age groups, whereas the association between self-rated literacy and cognitive functioning showed the opposite trend. Discussion. Self-rated literacy was found to be a better predictor of late-life cognitive functioning than was the level of formal education. The results have implications for studies of age-related differences in which education level is taken into account. PMID:22421808

Effective workplace interventions that consider the multifactorial nature of obesity are needed to reduce and prevent obesity among adults. Furthermore, the factors associated with obesity may differ for workers across age groups. Therefore, the objective of this study was to identify demographic, health-related, and work-related factors associated with baseline and changes in body mass index (BMI) and body fat percentage (BFP) and among Connecticut manufacturing workers acrossage groups. BMI and BFPof 758 workers from six Connecticut manufacturing companies were objectively measuredat two time points approximately 36 months apart. Demographic, health-related, and work-related factors wereassessed via questionnaire. All variables were included in linear regression models to identify factors associated with baseline and changes in BMI and BFP for workers in 3 age groups: <45 years (35 %), 45-55 years (37 %), >55 years (28 %). There were differences in baseline and changes in BMI and BFP among manufacturing workers across age groups. Being interested in changing weight was significantly (p < 0.01) associated with higher baseline BMI and BFP across all age categories. Other factors associated with higher baseline BMI and BFP differed by age group and included: male gender (BMI p = 0.04), female gender (BFP p < 0.01), not having a college education (BMI p = 0.01, BFP p = 0.04), having childcare responsibilities (BMI p = 0.04), and working less overtime (p = 0.02) among workers in the <45 year age category, male gender (BMI p = 0.02), female gender (BFP p < 0.01) and reporting higher stress in general (BMI p = 0.04) among workers in the 45-55 year age category, and female gender (BFP p < 0.01) and job tenure (BFP p = 0.03) among workers in the >55 year age category. Few factors were associated with change in BMI or BFP across any age category. Among manufacturing workers, we identified associations between individual

Previously, we showed that chronic testosterone administration increased body weight (BW) and food intake (FI), but did not alter fat weight, in young female rats. To examine our hypothesis that the effects of androgens on BW, FI and body composition might be age-dependent, the effects of chronic testosterone administration were evaluated in rats of different ages; i.e., young and middle-aged rats. Although chronic testosterone administration increased BW gain, FI, and feed efficiency in both young and middle-aged rats, it increased visceral fat weight in middle-aged rats, but not in young rats. Therefore, it is possible that testosterone promotes the conversion of energy to adipose tissue and exacerbates fat accumulation in older individuals. In addition, although the administration of testosterone increased the serum leptin level, it did not alter hypothalamic neuropeptide Y mRNA expression in middle-aged rats. On the contrary, the administration of testosterone did not affect the serum leptin levels of young rats. Thus, testosterone might induce hypothalamic leptin resistance, which could lead to fat accumulation in older individuals. Testosterone might disrupt the mechanisms that protect against adiposity and hyperphagia and represent a risk factor for excessive body weight and obesity, especially in older females.

The purpose of this study was to analyse body size indices of newborns in Vilnius city (Lithuania) during 2005-2010 in relation with mother's education and ethnicity, and in parallel with the changes of socio-economic situation during the recent years. The present results were based on data (N = 18,084) from the Vilnius University Clinic of Obstetrics and Gynaecology. Comparison of the present Lithuanian data with other newborn studies was made. The analysis of socio-economic and demographic indicators of Lithuania, and the comparison of Gross Domestic Product of various countries was performed. The comparison of body size of newborns' data from the different countries showed that Lithuanian newborns were among the biggest babies. Some statistically significant differences in body size of newborns from different ethnic groups were established. Body length of Lithuanian newborns (M = 52.6 cm, SD = 2.5) was higher than length of Russian, Ukrainian and Romanian newborns. Body weight of Lithuanian newborns (M = 3511 g, SD = 485) was bigger than birth weight of Russian, Polish, Ukrainian and Romanian newborns. The analysis of newborns size by mother's education showed that body weight of neonates from mothers with the university education and from each other education group was bigger in comparison with the babies from respectively lower education group. The comparison of newborns weight by mother's ethnicity in relation to education level revealed nearly no discrepancies between size of newborns from mothers with the same education level at different ethnic group. The analysis of birth parameters by year has not established a statistically significant difference between the mean values for the body weight and body length of the whole investigated contingent of the full-term, single-birth newborns from Vilnius city during the 2005-2010. However, the tendency has been revealed that newborns from mothers with lower education were the most susceptible to negative economic

Previous studies of theory of mind (ToM) in old age have provided mixed results. We predicted that educational level and cognitive processing are two factors influencing the pattern of the aging of ToM. To test this hypothesis, a younger group who received higher education (mean age 20.46 years), an older group with an education level equal to that of the young group (mean age 76.29 years), and an older group with less education (mean age 73.52 years) were recruited. ToM tasks included the following tests: the second-order false-belief task, the faux-pas task, the eyes test, and tests of fundamental aspects of cognitive function that included two background tests (memory span and processing speed) and three subcomponents of executive function (inhibition, updating, and shifting). We found that the younger group and the older group with equally high education outperformed the older group with less education in false-belief and faux-pas tasks. However, there was no significant difference between the two former groups. The three groups of participants performed equivalently in the eyes test as well as in control tasks (false-belief control question, faux-pas control question, faux-pas control story, and Eyes Test control task). The younger group outperformed the other two groups in the cognitive processing tasks. Mediation analyses showed that difficulties in inhibition, memory span, and processing speed mediated the age differences in false-belief reasoning. Also, the variables of inhibition, updating, memory span, and processing speed mediated age-related variance in faux-pas. Discussion focused on the links between ToM aging, educational level, and cognitive processing.

The purpose of this study was to examine the relationships between environmental factors, including household education, community violence exposure, racial discrimination, and cultural identity, and BMI in African American adolescents. A community-based sample of 198 African American youth (120 girls, 78 boys; ages 11-19 years) from Washtenaw County, Michigan, were included in this analysis. Violence exposure was assessed by using the Survey of Children's Exposure to Community Violence; racial discrimination by using the Adolescent Discrimination Distress Index; cultural identity by using the Acculturation, Habits, and Interests Multicultural Scale for Adolescents; and household education by using a seven-category variable. Measured height and body weight were used to calculate BMI. Racial discrimination was positively associated with BMI, whereas household education was inversely associated with BMI in African American adolescents (discrimination: β = 0.11 ± 0.04, p = 0.01; education: β = -1.13 ± 0.47, p = 0.02). These relationships were significant when accounting for the confounding effects of stress, activity, diet, and pubertal development. Significant gender interactions were observed with racial discrimination and low household education associated with BMI in girls only (discrimination: β = 0.16 ± 0.05, p = 0.003; education: β = -1.12 ± 0.55, p = 0.045). There were no significant relationships between culture, community violence exposure, and BMI (all p's > 0.05). Environmental factors, including racial discrimination and low household education, predicted higher BMI in African American adolescents, particularly among girls. Longitudinal studies are needed to better understand the mechanisms by which these environmental factors increase obesity risk in African American youth.

Menarche signifies the primary event in female puberty and is associated with changes in self-identity. It is not clear whether earlier puberty causes girls to spend less time in education. Observational studies on this topic are likely to be affected by confounding environmental factors. The Mendelian randomization (MR) approach addresses these issues by using genetic variants (such as single nucleotide polymorphisms, SNPs) as proxies for the risk factor of interest. We use this technique to explore whether there is a causal effect of age at menarche on time spent in education. Instruments and SNP-age at menarche estimates are identified from a Genome Wide Association Study (GWAS) meta-analysis of 182,416 women of European descent. The effects of instruments on time spent in education are estimated using a GWAS meta-analysis of 118,443 women performed by the Social Science Genetic Association Consortium (SSGAC). In our main analysis, we demonstrate a small but statistically significant causal effect of age at menarche on time spent in education: a 1 year increase in age at menarche is associated with 0.14 years (53 days) increase in time spent in education (95% CI 0.10-0.21 years, p = 3.5 × 10 -8 ). The causal effect is confirmed in sensitivity analyses. In identifying this positive causal effect of age at menarche on time spent in education, we offer further insight into the social effects of puberty in girls.

The incidence of diabetes mellitus is rising worldwide, and prediabetic screening for insulin resistance (IR) has become ever more essential. This study aimed to investigate whether body mass index (BMI), waist circumference (WC), or body fat percentage (BF%) could be a better predictor of IR in a middle-aged and elderly population. In this cross-sectional, community-based study, 394 individuals (97 with IR and 297 without IR) were enrolled in the analysis. IR was measured by homeostasis model assessment (HOMA-IR), and subjects with HOMA-IR value ≧75th percentile were defined as being IR. Associations between IR and BMI, WC and BF% were evaluated by t test, chi square, Pearson correlation, logistic regression, and receiver operating characteristic (ROC) curves. A total of 394 community-dwelling, middle-aged, and elderly persons were enrolled; 138 (35%) were male, and 256 were female (65%). The mean age was 64.41 ± 8.46 years. A significant association was identified between BMI, WC, BF%, and IR, with Pearson correlation coefficients of 0.437 (P < .001), 0.412 (P < .001), and 0.361 (P < .001), respectively. Multivariate logistic regression revealed BMI (OR = 1.31; 95% CI = 1.20-1.42), WC (OR = 1.13; 95% CI = 1.08-1.17), and BF% (OR = 1.17; 95% CI = 1.11-1.23) to be independent predictors of IR. The area under curves of BMI and WC, 0.749 and 0.745 respectively, are greater than that of BF% 0.687. BMI and WC were more strongly associated with IR than was BF%. Excess body weight and body fat distribution were more important than total body fat in predicting IR.

To examine the associations of body fatness, metabolic and inflammatory markers with retinal vessel calibers among children. We performed a population-based cohort study among 4145 school-age children. At the median age of 6.0 years (95% range 5.8, 8.0 years), we measured body mass index, total and abdominal fat mass, metabolic and inflammatory markers (blood levels of lipids, insulin and C-peptide and C-reactive protein) and retinal vascular calibers from retinal photographs. We observed that compared with normal weight children, obese children had narrower retinal arteriolar caliber (difference -0.21 s.d. score (SDS; 95% confidence interval (CI) -0.35, -0.06)), but not venular caliber. Continuous analyses showed that higher body mass index and total body fat mass, but not android/gynoid fat mass ratio and pre-peritoneal fat mass, were associated with narrower retinal arteriolar caliber (P<0.05 for body mass index and total body fat mass), but not with retinal venular caliber. Lipid and insulin levels were not associated with retinal vessel calibers. Higher C-reactive protein was associated with only wider retinal venular caliber (difference 0.10 SDS (95% CI 0.06, 0.14) per SDS increase in C-reactive protein). This latter association was not influenced by body mass index. Higher body fatness is associated with narrower retinal arteriolar caliber, whereas increased C-reactive protein levels are associated with wider retinal venular caliber. Increased fat mass and inflammation correlate with microvascular development from school-age onwards.

assessing relevance and effectiveness of care/educational technology in the form of "storytelling" as a strategy in the cultivation of active ageing (AA) for elderly users of a Basic Health Unit (BHU), from the Amazon region. convergent care research (CCR) held in a BHU in Belém, state of Pará, with eight elderly ladies for testing this technology. An active ageing assessment questionnaire and WHOQOL-BREF - quality of life assessment were applied. After training with a view to continuing education, elderly ladies told stories for an audience that addressed the question: "What did you learn from it for your life?" tThe popular stories elicited reactions from which the following categories emerged: solidarity; respect for the other; imagination, dreams, hopes and culture of the Amazonian. This practice had a positive result, producing changes in the quality of life of the elderly, particularly in the psychological domain. "storytelling" proved to be an innovative technology, a relevant and effective resource in health education, especially for active ageing.

[Purpose] This study attempted to examine whether Pilates is an effective exercise for improving the postural alignment and health of middle-aged women. [Subjects and Methods] The participants in this study were 36 middle-aged women (20 in the experimental group, 16 in the control group). The experimental group participated in Pilates exercise sessions three times a week for 12 weeks. Body alignment and composition measurements before and after applying the Pilates exercise program were performed with a body composition analyzer and a three-dimensional scanner. [Results] Postural alignment in the sagittal and horizontal planes was enhanced in the Pilates exercise group. Trunk alignment showed correlations with body fat and muscle mass. [Conclusion] The Pilates exercises are performed symmetrically and strengthen the deep muscles. Moreover, the results showed that muscle mass was correlated with trunk postural alignment and that the proper amount of muscle is critical in maintaining trunk postural alignment.

The associations between body image and attitudes toward obesity and thinness and their associations with measured body mass index (BMI) among female students of Kuwait University (n = 137) was examined in 2008. The body image perceptions were assessed using nine female silhouettes figures. The difference between current perceived body image (PBI) and ideal body image (IBI) was used as a measure of body image dissatisfaction (BID). Students tended to have a bigger PBI and smaller IBI than would be expected from their BMI category, leading to high levels of BID in each BMI category. PBI, IBI, BID, RBI were highly correlated with each other, and BMI was significantly correlated with each of them. The coefficients of these associations were not significantly altered in multiple regression analysis by the addition of potential confounding variables, such as age, marital status, physical activity, dieting behavior, parental education, and family size. These results suggest that PBI and a desire to be thinner were strongly related to BID and that thinness is becoming more desired in Kuwaiti society than the plump body image of the past.

Ageism and body esteem: associations with psychological well-being among late middle-aged African American and European American women.

PubMed

Sabik, Natalie J

2015-03-01

Social expectancy theory posits that cultural values shape how individuals perceive and evaluate others, and this influences how others evaluate themselves. Based on this theory, ageism may shape older individuals' self-evaluations. Given the cultural focus on beauty and youth, perceptions of age discrimination may be associated with lower body esteem, and this may be associated with poor psychological well-being. Because discrimination has been associated with poor health, and perceptions of health can affect body perceptions, subjective health status may also contribute to lower body esteem. These associations are assessed in a structural equation model for 244 African American and European American women in their early 60s. Perceptions of age discrimination and body esteem were associated with lower psychological well-being for both ethnic groups. Body esteem partially mediated the association between age discrimination and psychological well-being among European American women but not among African American women. Age-related discrimination is one source of psychological distress for older adults, though ageism's associations with body esteem, health, and psychological well-being vary significantly for European American and African American women. Examining body perceptions and health in the contexts of ageism and ethnicity is necessary when considering the psychological well-being of older women. © The Author 2013.

To date, there is no consensus regarding adult cutoffs of percentage of body fat or estimated cutoffs on the basis of nationally representative samples with rigorous body-composition measurements. We developed cutoffs of percentage of body fat on the basis of the relation between dual-energy x-ray absorptiometry-measured fat mass and BMI (in kg/m(2)) stratified by sex, age, and race-ethnicity by using 1999-2004 NHANES data. A simple regression (percentage of body fat = β(0) + β(1) × 1 ÷ BMI) was fit for each combination of sex (men and women), 3 age groups (18-29, 30-49, and 50-84 y of age), and 3 race-ethnicity groups (non-Hispanic whites, non-Hispanic blacks, and Mexican Americans). Model fitting included a consideration of complex survey design and multiple imputations. Cutoffs of percentage of body fat were computed that corresponded to BMI cutoffs of 18.5, 25, 30, 35, and 40 on the basis of estimated prediction equations. R(2) ranged from 0.54 to 0.72 for men (n = 6544) and 0.58 to 0.79 for women (n = 6362). In men, the percentage of body fat that corresponded to a BMI of 18.5, 25, 30, 35, and 40 across age and racial-ethnic groups ranged from 12.2% to 19.0%, 22.6% to 28.0%, 27.5% to 32.3%, 31.0% to 35.3%, and 33.6% to 37.6%, respectively; the corresponding ranges in women were from 24.6% to 32.3%, 35.0% to 40.2%, 39.9% to 44.1%, 43.4% to 47.1%, and 46.1% to 49.4%, respectively. The oldest age group had the highest cutoffs of percentage of body fat. Non-Hispanic blacks had the lowest cutoffs of percentage of body fat. Cutoffs of percentage of body fat were higher in women than in men. Cutoffs of percentage of body fat that correspond to the current US BMI cutoffs are a function of sex, age, and race-ethnicity. These factors should be taken into account when considering the appropriateness of levels of percentage of body fat.

Although discouraged, pacifier usage is widespread and often practiced beyond two years of age. The current study explored the effects of maternal education and dental visits on the age of pacifier withdrawal. The dental histories of 213 children (53.1% male) attending a primary school in Madrid were obtained along with maternal education level and age at pacifier withdrawal. Data were analyzed by using independent samples t-test, one-way ANOVA two-way ANOVA and a complementary non-parametric approach was also used. There was a significant effect of maternal education on the age of pacifier withdrawal; the higher the maternal education, the younger the age of withdrawal. The frequency of dental visits influenced the relationship between maternal education and the age of pacifier withdrawal. Dental visits considerably shortened pacifier use among children with low- and medium-educated mothers. Pediatric dentists play a critical role in the correction of unhealthy oral habits such as prolonged pacifier use. The educational component of pediatric dentistry could reverse the lack of knowledge or misinformation among high-risk groups (e.g. low maternal education). As a consequence, we recommend that children start dental visits at an early age and maintain visits with a high frequency.

The relationships between live weight and eight body measurements of West African Dwarf (WAD) goats were studied using 211 animals under farm condition. The animals were categorized based on age and sex. Data obtained on height at withers (HW), heart girth (HG), body length (BL), head length (HL), and length of hindquarter (LHQ) were fitted into simple linear, allometric, and multiple-regression models to predict live weight from the body measurements according to age group and sex. Results showed that live weight, HG, BL, LHQ, HL, and HW increased with the age of the animals. In multiple-regression model, HG and HL best fit the model for goat kids; HG, HW, and HL for goat aged 13-24 months; while HG, LHQ, HW, and HL best fit the model for goats aged 25-36 months. Coefficients of determination (R(2)) values for linear and allometric models for predicting the live weight of WAD goat increased with age in all the body measurements, with HG being the most satisfactory single measurement in predicting the live weight of WAD goat. Sex had significant influence on the model with R(2) values consistently higher in females except the models for LHQ and HW.

Association of sex and age with responses to lower-body negative pressure

The effects of age and sex on the human-body responses to -50 torr LBNP were investigated in subjects who have undergone LBNP tests at the Kennedy Space Center. The comparison of results obtained on women and age-matched men indicated that men had larger relative increases in calf circumference and greater increases in peripheral resistance during the exposure to LBNP than the women; on the other hand, women displayed greater increases in thoracic impedance and heart rate. The comparison of the results on men of different ages (between 29 and 56 y) indicated that older subjects had greater increases in peripheral resistance and less heart rate elevation in response to LBNP. It is suggested that the age-related circulatory differences were due to a reduction in vagal response and a switch to predominant sympathetic nervous system influence in older men.

The aim of this study was to record the age and body size of 23 captive female hawksbill turtles at the onset of follicular development. The age, straight carapace length (SCL), and body mass (BM) of the turtles were recorded between 2006 and 2014 at follicular development (determined via ultrasonography) these parameters were 17.7 ± 1.7 years (range: 13-20 years), 77.7 ± 3.3 cm (73.3-83.5 cm), and 61.1 ± 8.0 kg (48.2-76.1 kg), respectively. When the year of the onset of follicular development was designated year 0, the increase in SCL in years -7-0 and 0-3 averaged 2.2 cm and 1.0 cm, respectively. Correspondingly, the increase in BM in years -7-0 and 0-3 averaged 5.0 kg and 2.2 kg, respectively. This is the first study to report the age and body size of captive female hawksbill turtles at the onset of follicular development, which indicates the beginning of sexual maturation. The reduction in growth after follicular development suggests that at the onset of sexual maturation, female hawksbills may utilize energy for follicular development rather than growth. © 2014 Wiley Periodicals, Inc.

Abstract Background Body image (BI) and body satisfaction may be important in understanding weight loss behaviors, particularly during the postpartum period. We assessed these constructs among African American and white overweight postpartum women. Methods The sample included 162 women (73 African American and 89 white) in the intervention arm 6 months into the Active Mothers Postpartum (AMP) Study, a nutritional and physical activity weight loss intervention. BIs, self-reported using the Stunkard figure rating scale, were compared assessing mean values by race. Body satisfaction was measured using body discrepancy (BD), calculated as perceived current image minus ideal image (BD<0: desire to be heavier; BD>0: desire to be lighter). BD was assessed by race for: BDIdeal (current image minus the ideal image) and BDIdeal Mother (current image minus ideal mother image). Results Compared with white women, African American women were younger and were less likely to report being married, having any college education, or residing in households with annual incomes >$30,000 (all p < 0.01). They also had a higher mean body mass index (BMI) (p = 0.04), although perceived current BI did not differ by race (p = 0.21). African Americans had higher mean ideal (p = 0.07) and ideal mother (p = 0.001) BIs compared with whites. African Americans' mean BDs (adjusting for age, BMI, education, income, marital status, and interaction terms) were significantly lower than those of whites, indicating greater body satisfaction among African Americans (BDIdeal: 1.7 vs. 2.3, p = 0.005; BDIdeal Mother: 1.1 vs. 1.8, p = 0.0002). Conclusions Racial differences exist in postpartum weight, ideal images, and body satisfaction. Healthcare providers should consider tailored messaging that accounts for these racially different perceptions and factors when designing weight loss programs for overweight mothers. PMID:20113143

To determine associations between educational level and ophthalmic diseases in Chinese. The population-based Beijing Eye Study, performed in 2006, enrolled 3,251 participants (age: 45+ years) out of 4,439 subjects invited to participate (response rate: 73.2%). The participants underwent an interview including questions concerning their educational level, and a detailed ophthalmic examination. Data on the level of education were available for 3,221 (99.1%) subjects, with 1,484 (46.1%) subjects living in the rural region. The mean age was 60.4 +/- 10.1 years (range: 45-89 years). In a multivariate analysis, a higher level of education was significantly associated with myopic refractive error, higher best-corrected visual acuity, lower degree of nuclear cataract, and lower prevalence of angle-closure glaucoma, and with the systemic parameters of lower age, male gender, urban region, taller body height, and lower body mass index. It was not significantly associated with intraocular pressure, amount of subcapsular cataract and cortical cataract, cataract surgery, and the prevalences of diabetes mellitus, retinal vein occlusions, chronic open-angle glaucoma, and age-related macular degeneration, and with the systemic parameters of fasting serum concentrations of glucose, high-density lipoproteins, low-density lipoproteins, cholesterol and triglycerides, systolic and diastolic blood pressure. In the Greater Beijing area, a higher level of education was associated with myopic refractive error, higher best-corrected visual acuity, and lower prevalence of nuclear cataract and angle-closure glaucoma, after adjusting for the systemic parameters of younger age, male gender, urban region, taller body height, lower body mass index less smoking and less alcohol consumption. Educational level was not significantly associated with intraocular pressure, cortical cataract, blood pressure, and frequencies of age-related macular degeneration, retinal vein occlusions and chronic open

Body fat serves as a storage compartment for lipophilic pollutants and affects the pharmacokinetics of many toxic chemicals. Understanding how body fat varies with gender, strain, and age may be essential for development of experimental models to study mechanisms of toxicity. Nuclear magnetic resonance (NMR)-based analysis serves as a noninvasive means of assessing proportions of fat, lean, and fluid in rodents over their lifetime. The aim of this study was to track changes in body composition of male and female Long-Evans (LE), Sprague-Dawley (SD), Fischer (F334), and Brown Norway (BN) rats from postweaning over a >2-yr period. Percent fat of preweaned LE and SD rats was markedly higher compared to the other strains. LE and SD strains displayed marked increases in body fat from weaning to 8 mo of age. Postweaned F344 male and females showed relatively low levels of percent fat; however, at 2 yr of age percent fat of females was equal to that of SD and LE in females. BN rats showed the highest levels of lean tissue and lowest levels of fat. Percent fat of the BN strain rose at the slowest rate as they aged. Percent fluid was consistently higher in males for all strains. Females tended to have higher percent fat than males in LE, SD, and F344 strains. Assessing changes in body fat as well as lean and fluid of various strains of male and female rats over their lifetime may prove useful in many research endeavors, including pharmacokinetics of lipophilic toxicants, mechanisms underlying obesity, and metabolic disorders.

This study examined relations between children's attention span-persistence in preschool and later school achievement and college completion. Children were drawn from the Colorado Adoption Project using adopted and non-adopted children ( N = 430). Results of structural equation modeling indicated that children's age 4 attention span-persistence significantly predicted math and reading achievement at age 21 after controlling for achievement levels at age 7, adopted status, child vocabulary skills, gender, and maternal education level. Relations between attention span-persistence and later achievement were not fully mediated by age 7 achievement levels. Logistic regressions also revealed that age 4 attention span-persistence skills significantly predicted the odds of completing college by age 25. The majority of this relationship was direct and was not significantly mediated by math or reading skills at age 7 or age 21. Specifically, children who were rated one standard deviation higher on attention span-persistence at age 4 had 48.7% greater odds of completing college by age 25. Discussion focuses on the importance of children's early attention span-persistence for later school achievement and educational attainment.

Age, educational experiences, language and culture can affect linguistic-cognitive performance. This is the first systematic study investigating linguistic-cognitive aging in Greek Cypriot adults focusing on executive functioning (EF) and oral naming performance. Three hundred and fifty-nine participants were included, a group of young-old, aged 60-75 years (n = 231), and a group of old-old participants, aged 76 years and older (n = 128). Participants in each age group were divided into three education groups: 0-4 years (n = 50), 5-9 years (n = 198), and 10 years of education and higher (n = 111). Participants were administered 5 measures of EF along with measures of receptive vocabulary and confrontational naming. There was a significant relationship between the EF composite score and all language measures. MANOVA (α = 0.05) indicated significant age and education effects on most measures of EF and language. Performance on receptive vocabulary and cognitive shift remained stable across age groups, but was mediated by education. Education plays a significant role on all measures requiring semantic organization, speed of information processing, cognitive shift, mental flexibility, receptive vocabulary and confrontational naming. Furthermore, strategic thinking has a role in semantic knowledge, word retrieval and semantic access in healthy aging. We conclude with clinical implications and assessment considerations in aphasia.

Malnutrition in children under 5 years of age (U5s) is a serious public health problem in low- and middle-income countries including Bangladesh. Improved maternal education can contribute effectively to reduce child malnutrition. We examined the long-term impact of maternal education on the risk of malnutrition in U5s and quantified the level of education required for the mothers to reduce the risk. We used pooled data from five nationwide demographic and health surveys conducted in 1996-1997, 1999-2000, 2004, 2007 and 2011 in Bangladesh involving 28 941 U5s. A log-binomial regression model was used to examine the association between maternal education (no education, primary, secondary or more) and malnutrition in children, measured by stunting, underweight and wasting controlling for survey time, maternal age, maternal body mass index, maternal working status, parity, paternal education and wealth quintile. An overall improvement in maternal educational attainment was observed between 1996 and 2011. The prevalence of malnutrition although decreasing was consistently high among children of mothers with lower education compared with those of mothers with higher education. In adjusted models incorporating time effects, children of mothers with secondary or higher education were at lower risk of childhood stunting [risk ratio (RR): 0.86, 95% confidence interval (CI): 0.81, 0.89], underweight (RR: 0.83, 95% CI: 0.78, 0.88) and wasting (RR: 0.82, 95% CI: 0.74, 0.91) compared with children of mothers with no education. We demonstrated the importance of promoting women's education at least up to the secondary level as a means to tackle malnutrition in Bangladesh. © 2015 John Wiley & Sons Ltd.

The reference charts of sitting height (SH), subischial leg length (LL) and the sitting height/leg length ratio (SH/LL) are useful tools in assessing body proportion for clinicians and researchers in related areas. However, reference charts of body proportions for Chinese children and adolescents are limited. To construct reference charts of SH, LL and SH/LL for Chinese children and adolescents. Stature and sitting height of 92 494 (46 240 boys and 46 254 girls) healthy Han nationality children, aged 0-18 years, were measured in two national large-scale cross-sectional surveys in 2005 in China. SH/LL was selected as the indicator of body proportion. References of SH, LL and SH/LL were constructed using the LMS method. The reference charts demonstrated that SH and LL increased with age. Growth in SH slowed by the age of 17 years in boys and 15 years in girls. Similarly, growth in LL slowed at 16 years in boys and 14 years in girls. The SH/LL ratio declined from birth (2.00 in boys and 2.03 in girls) to 13 years in boys (1.11) and to 11 years in girls (1.13), then increased slightly to the age of 18 (1.16 in boys and 1.18 in girls). The gender difference of SH/LL was not significantly different before the age of 11 years. After the age of 11, SH/LL appeared elevated in girls compared to boys. The reference charts of SH, LL and SH/LL are useful tools for assessing body proportions for Chinese children and adolescent individuals.

2005-07-01

Mean values of different body dimensions in different age cohorts of children make it possible to learn a lot about their dynamic changes. Their comparative analysis, as is usually practiced, in fact leads to a simple description of changes in measurement units (mm or cm) at the average level of some body dimension during a shorter or longer period of time. To estimate comparative intensity of the growth process of different body dimensions, the authors use the analogue of Mahalanobis distance, the so-called Kullback divergence (1967), which does not demand stability of dispersion or correlation coefficients of dimensions in compared cohorts of children. Most of the dimensions, excluding skinfolds, demonstrate growth dynamics with gradually reducing increments from birth to 7 years. Body length has the highest integrative increment, leg length about 94% of body length, body mass 77%, and trunk and extremities circumferences 56%. Skinfolds have a non-monotonic pattern of accumulated standardized increments with some increase until 1-2 years of age.

Little is known about the secular trends in age at spermarche among boys, and the association between body mass index (BMI) and male puberty is controversial. This study aimed to estimate the trend in age at spermarche in China and explore the association of spermarche with BMI. We used four cross-sectional Chinese National Surveys on Students' Constitution and Health (CNSSCH; 1995, 2000, 2005 and 2010). Median age at spermarche was determined using probit analysis. Logistic regression was used to assess the association of spermarche with BMI. Age at spermarche among Chinese boys dropped from 14.57 to 14.03 years from 1995 to 2010 with a decrease of 4.3 months per decade. Boys with BMI-for-age z-score lower than -2 had the latest age at spermarche. A higher BMI or BMI-for-age z-score was associated with an increased likelihood of having reached spermarche, and this association was consistently observed at all survey points. This study provides important evidence of a secular trend of earlier age at spermarche over the past 15 years in China, and this decrease was accompanied by a simultaneous increase in BMI. Strategies and interventions focusing on thinness may promote both their nutritional status and puberty development among Chinese boys. © 2015 World Obesity.

To quantify the mediating role of leisure time physical activity (LTPA) and five dietary behaviours on educational differences in 13-year body mass index (BMI) gain across adulthood. Participants from the Melbourne Collaborative Cohort Study (4791 women; 3103 men) who maintained or gained BMI over 1990-1994 to 2003-2007 and met our inclusion criteria were selected. Education, potential mediators and confounders (age, alcohol, and smoking) were measured at baseline. We conducted sex-specific multiple mediation analyses using MacKinnon's product of coefficients method. A higher educational attainment was associated with a 0.27 kg m -2 (95% CI 0.14, 0.39) lesser 13-year BMI gain among women only. We observed significant indirect effects of educational attainment on 13-year BMI gain through LTPA and nutrient-rich foods (each associated with a higher educational attainment and lesser 13-year BMI gain) and diet soft drink (associated with a lower educational attainment and greater 13-year BMI gain), which mediated 10, 15 and 20% of this relationship, respectively (45% in total). Nutrient-rich foods, LTPA and diet soft drink may represent effective public health targets to reduce inequities in excess weight across adulthood.

Ageing is thought to participate to the pathogenesis of sporadic inclusion-body myositis (s-IBM). Although the regenerative potential of s-IBM muscle is reduced in vivo, age-related abnormalities of satellite cells possibly accounting for the decline of muscle repair have not been demonstrated. Here we show that proliferation rate and clonogenicity of s-IBM myoblasts are significantly lower and doubling time is longer than normal age-matched controls, indicating that proliferative capacity of s-IBM muscles becomes exhausted earlier. Telomere shortening is detected in s-IBM cells suggesting premature senescence. Differently from controls, s-IBM myoblasts show increased active beta-catenin mainly localized within myonuclei, indicating active Wnt stimulation. After many rounds of muscle growth, only s-IBM myoblasts accumulate congophilic inclusions and immunoreactive Abeta(1-40) deposits. Therefore, s-IBM myoblasts seem to have a constitutively impaired regenerative capacity and the intrinsic property, upon sufficient aging in vitro, to accumulate Abeta. Our results might be valuable in understanding molecular mechanisms associated with muscle aging underlying the defective regeneration of s-IBM muscle and provide new clues for future therapeutic strategies.

Although exact causes of Parkinson disease (PD) remain enigmatic, mitochondrial dysfunction is increasingly appreciated as a key determinant of dopaminergic neuron susceptibility in both familial and sporadic PD. Two genes associated with recessive, early-onset PD encode the ubiquitin (Ub) kinase PINK1 and the E3 Ub ligase PRKN/PARK2/Parkin, which together orchestrate a protective mitochondrial quality control (mitoQC) pathway. Upon stress, both enzymes cooperatively identify and decorate damaged mitochondria with phosphorylated poly-Ub (p-S65-Ub) chains. This specific label is subsequently recognized by autophagy receptors that further facilitate mitochondrial degradation in lysosomes (mitophagy). Here, we analyzed human post-mortem brain specimens and identified distinct pools of p-S65-Ub-positive structures that partially colocalized with markers of mitochondria, autophagy, lysosomes and/or granulovacuolar degeneration bodies. We further quantified levels and distribution of the 'mitophagy tag' in 2 large cohorts of brain samples from normal aging and Lewy body disease (LBD) cases using unbiased digital pathology. Somatic p-S65-Ub structures independently increased with age and disease in distinct brain regions and enhanced levels in LBD brain were age- and Braak tangle stage-dependent. Additionally, we observed significant correlations of p-S65-Ub with LBs and neurofibrillary tangle levels in disease. The degree of co-existing p-S65-Ub signals and pathological PD hallmarks increased in the pre-mature stage, but decreased in the late stage of LB or tangle aggregation. Altogether, our study provides further evidence for a potential pathogenic overlap among different forms of PD and suggests that p-S65-Ub can serve as a biomarker for mitochondrial damage in aging and disease.

We aimed to investigate the relationship between education and cortical thickness in cognitively normal individuals to determine whether education attenuated the association of advanced aging and cortical thinning. A total of 1,959 participants, in whom education levels were available, were included in the final analysis. Cortical thickness was measured on high-resolution MRIs using a surface-based method. Multiple linear regression analysis was performed for education level and cortical thickness, after controlling for possible confounders. High levels of education were correlated with increased mean cortical thickness throughout the entire cortex (p = 0.003). This association persisted after controlling for vascular risk factors. Statistical maps of cortical thickness showed that the high levels of education were correlated with increased cortical thickness in the bilateral premotor areas, anterior cingulate cortices, perisylvian areas, right superior parietal lobule, left lingual gyrus, and occipital pole. There were also interactive effects of age and education on the mean cortical thickness (p = 0.019). Our findings suggest the protective effect of education on cortical thinning in cognitively normal older individuals, regardless of vascular risk factors. This effect was found only in the older participants, suggesting that the protective effects of education on cortical thickness might be achieved by increased resistance to structural loss from aging rather than by simply providing a fixed advantage in the brain. © 2015 American Academy of Neurology.

The central arteries stiffen with age, causing hemodynamic alterations that have been associated with cardiovascular events. Changes in body fat with age may be related to aortic stiffening. The association between vascular stiffness and body fat was evaluated in 2488 older adults (mean age, 74 years; 52% female; 40% black) enrolled in the Study of Health, Aging, and Body Composition (Health ABC), a prospective study of changes in weight and body composition. Clinical sites were located in Pittsburgh, Pa, and Memphis, Tenn. Aortic pulse wave velocity was used as an indirect measure of aortic stiffness. A faster pulse wave velocity indicates a stiffer aorta. Body fat measures were evaluated with dual energy x-ray absorptiometry and computed tomography. Independent of age and blood pressure, pulse wave velocity was positively associated with weight, abdominal circumference, abdominal subcutaneous fat, abdominal visceral fat, thigh fat area, and total fat (P<0.001 for all). The strongest association was with abdominal visceral fat. Elevated pulse wave velocity was also positively associated with history of diabetes and higher levels of glucose, insulin, and hemoglobin A1c (P<0.001 for all). In multivariate analysis, independent positive associations with pulse wave velocity were found for age, systolic blood pressure, heart rate, abdominal visceral fat, smoking, hemoglobin A1c, and history of hypertension. The association between pulse wave velocity and abdominal visceral fat was consistent across tertiles of body weight. Among older adults, higher levels of visceral fat are associated with greater aortic stiffness as measured by pulse wave velocity.

The sexuality of the elderly is rarely mentioned in general medicine although it holds an important place in many old people's life, and sexual well-being is a part of the global well-being according to the World Health Organization. To explore the representations of their own sexuality and aging body by the elderly. Qualitative study using semi-structured interviews in 15 healthy elderly people over 65 years of age, living at home. In-depth interviews were transcribed and submitted to qualitative content using a phenomenological and a psychodynamic analysis. The phenomenological approach allows to explore the meaning and significance of the sexuality of older people (their representations and individual experience). The psychodynamic approach allows an analysis of defense mechanisms in verbal and nonverbal behavior. Some elderly maintain a view of their sexuality in accordance with the societal standards existing before the sexual liberalization following the events of May 68 in France. For these people, sexuality is tabooed and only linked to procreation, no longer part of the aging body, and perceived as degraded, then difficult to be approached by general practitioners in relation with defense mechanisms. Other elderly people have managed to free themselves from those previous societal standards. The notion of pleasure is still present in these people and their aging body is perceived as an altered body, difficult to be accepted on account of the pressure for conformity due to actual societal standards. These standards reserve sexuality to young people and convey a picture of a sexuality that would be improper for the elderly. Understanding the representations of their sexuality by the elderly allows GPs a better approach for helping older patients to improve their sexual well-being.

[Purpose] This study attempted to examine whether Pilates is an effective exercise for improving the postural alignment and health of middle-aged women. [Subjects and Methods] The participants in this study were 36 middle-aged women (20 in the experimental group, 16 in the control group). The experimental group participated in Pilates exercise sessions three times a week for 12 weeks. Body alignment and composition measurements before and after applying the Pilates exercise program were performed with a body composition analyzer and a three-dimensional scanner. [Results] Postural alignment in the sagittal and horizontal planes was enhanced in the Pilates exercise group. Trunk alignment showed correlations with body fat and muscle mass. [Conclusion] The Pilates exercises are performed symmetrically and strengthen the deep muscles. Moreover, the results showed that muscle mass was correlated with trunk postural alignment and that the proper amount of muscle is critical in maintaining trunk postural alignment. PMID:27390396

The sweeping obesity epidemic could further increase the incidence of functional limitations in the U.S. rapidly aging population. To examine the relationship between body weight status and onset of functional limitations in U.S. middle-aged and older adults. Study sample came from 1992 to 2010 waves of the Health and Retirement Study, a nationally representative longitudinal survey of community-dwelling middle-aged and older adults. Body mass index (BMI) was calculated from self-reported height/weight. Functional limitations were classified into physical mobility limitation (PM), large muscle function limitation (LMF), activities of daily living limitation (ADL), gross motor function limitation (GMF), and fine motor function limitation (FMF). Mixed-effect logistic regressions were performed to estimate the relationship between prior-wave body weight status and current-wave onset of functional limitations, adjusted for individual characteristics and survey design. Prior-wave body weight status prospectively predicted onset of functional limitation, and the relationship showed a U-shaped pattern. Compared with their normal weight counterparts, the odds ratios (ORs) in underweight (BMI < 18.5) and obese (BMI ≥ 30) adults were 1.30 (95% confidence interval, 1.05-1.62) and 2.31 (2.11-2.52) for PM, 1.20 (0.96-1.50) and 1.63 (1.49-1.79) for LMF, 2.02 (1.66-2.46) and 1.40 (1.28-1.54) for ADL, 1.96 (1.60-2.39) and 1.77 (1.62-1.93) for GMF, and 1.66 (1.37-2.02) and 1.34 (1.22-1.46) for FMF, respectively. For PM, LMF and GMF, the impact of obesity appeared more pronounced in women, whereas that of underweight more pronounced in men. Proper weight management during aging is crucial in preventing functional limitations in middle-aged and older adults. Copyright © 2015 Elsevier Inc. All rights reserved.

Cardiac rehabilitation (CR) is the standard procedure in persons after coronary artery bypass grafting (CABG). Its basic aim is to combat coronary heart disease (CHD) risk factors through physical activity and normalization of body mass. Many authors highlight the differences in response to training in CR as dependent on gender, age and occurrence of accompanying disease. The aim of this study is to assess the effectiveness of a three-week early CR in reference to changing body composition parameters in patients over 50 years of age. The study involved a random group of 65 patients (44 men and 21 women) between the ages of 50-76 (average: 62.6 ± 7.2) years with CHD following CABG. Anthropometric and body composition (bioelectrical impedance method) measurements were taken at the commencement of CR and after the training programme. After CR, body mass and body mass index were reduced in men < 65 and ≥ 65 years, and in women <65 years. A reduction % body fat and increase % fat free mass and % total body water was observed only in patients <65. years. Furthermore, in men < 65 years, an increase in % body cell mass was observed. In women ≥ 65 years, no statistically significant changes were observed in body fat indices and body composition features between initial and final study. Patients ≥ 65 years of age following surgery over a period of hospital cardiac rehabilitation do not experience the same significant improvement in body composition parameters associated with risk of CHD as middle-aged adults. Older women post-cardiac surgery are characterized by a higher disability index in relation to tolerance to physical stress in comparison with men of the same age and persons < 65 years of age.

Chronic pain has large health care costs and a major impact on the health of those affected. Few studies have also considered the severity of pain in different parts of the body across all age groups. To measure the prevalence and troublesomeness of musculoskeletal pain in different body locations and age groups, in a consistent manner, without using location specific health outcome measures. A cross-sectional postal survey of 4049 adults registered with 16 MRC General Practice Research Framework practices. Frequency of chronic pain overall and troublesome pain by location and age was calculated. Logistic regression was undertaken to explore the relationship between chronic pain and demographic factors. We received 2504 replies; response rate 60%. The prevalence of chronic pain was 41%. The prevalence of chronic pain rose from 23% in 18-24 year olds reaching a peak of 50% in 55-64 year olds. Troublesome pain over the last 4 weeks was commonest in the lower back (25%), neck (18%), knee (17%) and shoulder (17%). Troublesome wrist, elbow, shoulder, neck and lower back pain were most prevalent in the 45- to 64-year-age groups. Troublesome hip/thigh, knee and ankle/foot pain were most prevalent in those aged 75 or more. Great efforts have been made to develop and test treatments for low back pain. Our findings suggest that the overall prevalence of troublesome neck, knee and shoulder pain approaches that of troublesome low back pain and that similar efforts may be required to improve the management these pains.

To examine unintentional drowning mortality by age and body of water across 60 countries, to provide a starting point for further in-depth investigations within individual countries. The latest available three years of mortality data for each country were extracted from WHO Health Statistics and Information Services (updated at 13 November 2013). We calculated mortality rate of unintentional drowning by age group for each country. For countries using International Classification of Disease 10 (ICD-10) detailed 3 or 4 Character List, we further examined the body of water involved. A huge variation in age-standardised mortality rate (deaths per 100 000 population) was noted, from 0.12 in Turkey to 9.19 in Guyana. Of the ten countries with the highest age-standardised mortality rate, six (Belarus, Lithuania, Latvia, Russia, Ukraine and Moldova) were in Eastern Europe and two (Kazakhstan and Kyrgyzstan) were in Central Asia. Some countries (Japan, Finland and Greece) had a relatively low rank in mortality rate among children aged 0-4 years, but had a high rank in mortality rate among older adults. On the contrary, South Africa and Colombia had a relatively high rank among children aged 0-4 years, but had a relatively low rank in mortality rate among older adults. With regard to body of water involved, the proportion involving a bathtub was extremely high in Japan (65%) followed by Canada (11%) and the USA (11%). Of the 13 634 drowning deaths involving bathtubs in Japan between 2009 and 2011, 12 038 (88%) were older adults aged 65 years or above. The percentage involving a swimming pool was high in the USA (18%), Australia (13%), and New Zealand (7%). The proportion involving natural water was high in Finland (93%), Panama (87%), and Lithuania (85%). After considering the completeness of reporting and quality of classifying drowning deaths across countries, we conclude that drowning is a high-priority public health problem in Eastern Europe, Central Asia
