    Normal human aging is accompanied by progressive brain tissue loss and cognitive decline; however, several factors are thought to influence brain aging. We applied tensor-based morphometry to high-resolution brain MRI scans to determine whether educational level or physical activity was associated with brain tissue volumes in the elderly, particularly in regions susceptible to age-related atrophy. We mapped the 3D profile of brain volume differences in 226 healthy elderly subjects (130F/96M; 77.9 ± 3.6 SD years) from the Cardiovascular Health Study-Cognition Study. Statistical maps revealed the 3D profile of brain regions whose volumes were associated with educational level and physical activity (based on leisure-time energy expenditure). After controlling for age, sex, and physical activity, higher educational levels were associated with ~2-3% greater tissue volumes, on average, in the temporal lobe gray matter. After controlling for age, sex, and education, greater physical activity was associated with ~2-2.5% greater average tissue volumes in the white matter of the corona radiata extending into the parietal-occipital junction. Body mass index (BMI) was highly correlated with both education and physical activity, so we examined BMI as a contributing factor by including physical activity, education, and BMI in the same model; only BMI effects remained significant. This is one of the largest MRI studies of factors influencing structural brain aging, and BMI may be a key factor explaining the observed relationship between education, physical activity, and brain structure. Independent contributions to brain structure could not be teased apart as all these factors were highly correlated with one another.

    Introduction One of systemic changes connected to body ageing is the change of body content and the possibility of formation and/or intensification of insulin resistance, dyslipidemia and hypertension symptoms. Material and methods The research was conducted on 68 women aged 65-85 with body mass index (BMI) of 25.3 to 44.5 kg/m2 who have been educated for four months. The energy and nutritive value of 204 daily food rations (DFRs) was evaluated twice: first days of October and – after the diet correction and implementation of the basic rules – from the end of January. The measurements, anthropometric and body content (in 35 women under research) with the bio-impedance method was checked twice – before and after completing the education. Results After completing the education, there was a statistically significant increase in consumption of grain products, fermented milk products, potatoes, fruit and vegetables, as well as seeds of legumes. Consumption of meat and cold meats, sugar and sweets significantly decreased. In the course of education, an individual-specific decrease in body mass of the participants was noticed, which found its reflection in positive changes of the anthropometric indicators value. A significant decrease in fat content in bodies of women under research was also noticed, which was accompanied by a slight increase in fat-free body mass and water. Conclusions The four-month pro-health education of women influenced changes in improper nutrition habits resulting in, besides the improvement of organism functions and well-being of women under research, body mass loss and changes in content of the body.

    In this article, we examine the existing sociocultural research and theory concerned with the aging body. In particular, we review the body image and embodiment literatures and discuss what is known about how older adults perceive and experience their aging bodies. We analyse how body image is shaped by age, culture, ethnicity, gender, health status, sexual preference, and social class. Additionally, we critically elucidate the embodiment literature as it pertains to illness experiences, sexuality, the everyday management of the aging body, appearance work, and embodied identity. By outlining the key findings, theoretical debates, and substantive discrepancies within the body image and embodiment research and theory, we identify gaps in the literature and forecast future, much-needed avenues of investigation.

    Seventy-four European American women aged 50-68 years completed surveys of menopausal attitudes, appearance aging anxiety, body esteem, body surveillance, and body shame. Hypotheses based on the connections between cultural constructions of femininity and menopause were partially supported. Menopausal attitudes and appearance-related aging anxiety were related to body surveillance. Appearance-related menopausal attitudes were related to both body surveillance and body esteem. Body shame moderated the relationship between appearance-related menopausal attitudes and body esteem.

    Identifying the factors that influence the body image of body builders is important for understanding this construct. The aim of this study was to analyze the association between body image and age, socioeconomic status, and place of residence of body builders from two cities in Brazil. A cross-sectional study of 301 body builders with an average age of 25.2 yr. (SD = 3.5) was carried out. The Muscle Silhouette Measure scale was used, in which the discrepancy between current and desired silhouette was examined. Older body builders showed greater discrepancy between current and desired silhouette, reflecting their desire for a more muscular body.

    2014 is turning out to be a watershed year for celestial events involving the solar system's unsung heroes, small bodies. This includes the close flyby of comet C/2013 A1 / Siding Spring with Mars in October and the historic Rosetta mission with its Philae lander to comet 67P/Churyumov-Gerasimenko. Beyond 2014, the much anticipated 2015 Pluto flyby by New Horizons and the February Dawn Mission arrival at Ceres will take center stage. To deliver the excitement and wonder of our solar system's small bodies to worldwide audiences, NASA's JPL and GSFC education teams in partnership with NASA EDGE will reach out to the public through multiple venues including broadcast media, social media, science and math focused educational activities, observing challenges, interactive visualization tools like "Eyes on the Solar System" and more. This talk will highlight NASA's focused education effort to engage the public in small bodies mission science and the role these objects play in our understanding of the formation and evolution of the solar system.

    2014-02-01

    Using the major format identified for successful prevention and intervention work, five "W" questions: what, why, whom, where, and who, plus one: how, this article first summarizes the current body art literature. Then, educational strategies specifically regarding the topic of tattoos and body piercing are presented for school nurses. These strategies can be used to create applicable, realistic information for young students before they are faced with decisions related to body art. The school nurse might be the first and only credible source of information the students receive related to body art in an education/health environment. Curriculum emphasis is on the decision making leading up to the action, and the major purposes, rather than on the markings or jewelry associated with procurement. Reducing decisional conflict while promoting positive development in the areas of empowerment, self-esteem, and maturing can help achieve stronger informed decision making.

    Obesity and sarcopenia are health problems associated with ageing. The present study modelled the longitudinal changes in body composition of healthy men, aged from 20 to 96 years, and evaluated the fidelity of BMI to identify age-dependent changes in fat mass and fat-free mass. The data from 7265 men with multiple body composition determinations (total observations 38,328) were used to model the age-related changes in body mass, fat mass, fat-free mass, BMI and percentage of body fat. Changes in fat mass and fat-free mass were used to evaluate the fidelity of BMI and to detect body composition changes with ageing. Linear mixed regression models showed that all trajectories of body composition with healthy ageing were quadratic. Fat mass, BMI and percentage of body fat increased from age 20 years and levelled off at approximately 80 years. Fat-free mass increased slightly from age 20 to 47 years and then declined at a non-linear rate with ageing. Levels of aerobic exercise had a positive influence on fat mass and a slight negative effect on fat-free mass. BMI and percentage of body fat were sensitive in detecting the increase in fat mass that occurred with healthy ageing, but failed to identify the loss of fat-free mass that started at age 47 years.

    2012-01-01

    With the growing pervasiveness of mass media, individuals of all ages and both sexes are bombarded with images that glorify youthfulness, messages that tie self-worth to thinness, and products that promise youth and beauty forever. Aging women are vulnerable to these societal messages and experience strong pressures to maintain their youth and thinness. As the physiological changes that accompany normal aging move these women farther from the "ideal" image, body dissatisfaction may increase. These women are confronted with the impossible task of trying to defy the natural process of aging through a variety of means, including fashion, cosmetics, selective surgeries, and personal food choices. The resulting body image issues, weight preoccupation, and eating disturbances can lead to voluntary food restriction, depression, social withdrawal, lower self-esteem, and disordered eating, all of which can have a negative impact on quality of life and nutritional status. In this review we explore existing research on body dissatisfaction among middle-aged (30 to 60) and older (over 60) women, discuss the prevalence of body dissatisfaction, its predisposing risk factors, and the resulting eating and body maintenance behaviours, and examine implications for dietetic practice.

    Objective To examine the ability of various body mass index (BMI)–for-age categories, including the Centers for Disease Control and Prevention’s 85th to 94th percentiles, to correctly classify the body fatness of children and adolescents. Design Cross-sectional. Setting The New York Obesity Research Center at St Luke’s–Roosevelt Hospital from 1995 to 2000. Participants Healthy 5- to 18-year-old children and adolescents (N=1196) were recruited in the New York City area through newspaper notices, announcements at schools and activity centers, and word of mouth. Main Outcome Measures Percent body fat as determined by dual-energy x-ray absorptiometry. Body fatness cutoffs were chosen so that the number of children in each category (normal, moderate, and elevated fatness) would equal the number of children in the corresponding BMI-for-age category (<85th percentile, 85th–94th percentile, and ≥95th percentile, respectively). Results About 77% of the children who had a BMI for age at or above the 95th percentile had an elevated body fatness, but levels of body fatness among children who had a BMI for age between the 85th and 94th percentiles (n=200) were more variable; about one-half of these children had a moderate level of body fatness, but 30% had a normal body fatness and 20% had an elevated body fatness. The prevalence of normal levels of body fatness among these 200 children was highest among black children (50%) and among those within the 85th to 89th percentiles of BMI for age (40%). Conclusion Body mass index is an appropriate screening test to identify children who should have further evaluation and follow-up, but it is not diagnostic of level of adiposity. PMID:19736333

    PubMed

    Wolfinger, Martina

    2008-06-01

    The body is more than a biological basic condition; it is provided with social meanings and used for constructing, defining and describing age(ing) in different contexts. The social significance of the body can, for example, be seen by the fact that it is a bearer of age attributes, serves as a display surface and a knowledge bearer for the "normal" and "natural" aging process. Formal and informal chronological age limits are used to describe, divide etc. ageing, without expatiating that certain interpretations of physical attributes are the basis of this construction. In the scientific discourse and in everyday understanding, dichotomous views on the aging body "old means ill" and "successfully old means active" prevail. After a social constructivism and phenomenology discussion, about these socially significant connections of aging and body they are discussed exemplarily based on two interviews. It excerpts that the body-related significance of ageing turns out to be considerably more differentiated in everyday understanding. Therefore, a first intermediate conclusion for research and practice concerning the social significance of the body in the gerontological field has to be reached.

  9. 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

    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.

    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.

    We developed several techniques that provide data on body elemental composition from in vivo measurements in rats. These methods include total body potassium by whole-body counting of endogenous {sup 40}K; total body calcium (TBCa), sodium and chloride by in vivo neutron activation analysis and total body phosphorus (TBP) and nitrogen (TBN) by photon activation analysis. These elements provide information on total body fat, total body protein and skeletal mass. Measurements were made in 6-, 12- and 24-month-old rats. TBN Increased slightly between 6 and 12 months but was significantly lower by 24 months, indicating a substantial loss in total body protein. Working at the National Synchrotron light Source, we studied rat femurs by computed microtomography (CMT), and the elemental profile of the femur cortex by synchrotron-radiation induced X-ray emission (SRIXE). Although there were no significant changes in TBCA and TBP, indices of skeletal mass, CMT revealed a marked increase in the size and number of cavities in the endosteal region of the femur cortex with increasing age. The SRIXE analysis of this cortical bone revealed a parallel decrease in the endosteal Ca/P ratio. Thus, there are major alterations in bone morphology and regional elemental composition despite only modest changes in total skeletal mass.

  17. 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.

  18. Age modulates attitudes to whole body donation among medical students.

    Perry, Gary F; Ettarh, Raj R

    2009-01-01

    Managing a whole body donor program is necessary for facilitating a traditional dissection-based anatomy curriculum in medicine and health sciences. Factors which influence body donations to medical science can therefore affect dissection-based anatomy teaching. In order to determine whether age influences the attitudes of medical students to donations, this study surveyed, by Likert-type questionnaires, first-year graduate-entry medical students attending a dissection-based anatomy course. In contrast to attitudes among younger traditional-entry medical students, initial support for whole body donation by an unrelated stranger (83.8%), a family member (43.2%) or by the respondent (40.5%) did not decrease among graduate-entry medical students after exposure to dissection although there was a significant shift in strength of support for donation by stranger. This suggests that older medical students do not readily modify their pre-established attitudes to the idea of whole body donation after exposure and experience with dissection. Initial ambivalence among respondents to the idea of donation by family member was followed by opposition to this type of donation. These findings demonstrate that age modulates the influences on a priori attitudes to whole body donation that exposure to dissection causes in younger medical students.

    The complex interplay of education, age, and cognitive performance on various neuropsychological tests is examined in the current study. New education indices were formulated and further investigated to reveal how age and education variances work together to account for performance on neuropsychological tests. Participants were 830 English-speaking ethnic Chinese. Neuropsychological measures such as Verbal Memory, Digit Sequencing, Token Motor Task, Semantic Fluency, Symbol Coding, Tower of London, Judgment of Line Orientation, and Matrix Reasoning of the Wechsler Adult Intelligence Scale were administered. Education was measured by total years of education and adjusted years of education, as well as ratios of both measures with age. Age and education were associated with neuropsychological performance. Adjusted years of education was associated with fluency and higher cognitive processes, while the ratio between adjusted years of education and age was associated with tasks implicating working memory. Changes in education modalities implicated tasks requiring language abilities. Education and age represent key neurodevelopmental milestones. In light of our findings, special consideration should to be given when neuropsychological assessments are carried out in cross-cultural contexts and in societies where educational systems and pedagogy tend to be complex.

    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.

  3. Being cool: how body temperature influences ageing and longevity.

    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.

    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.

    This study was conducted to assess the relationship between body composition and suicidal ideation among the Korean elderly population (n = 302; ≥ 65 years) who participated in the Hallym Aging Study in 2010. Body composition was measured using dual-energy X-ray absorptiometry, and obesity was measured by the indices of body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), and body fat percentage. Sarcopenia was defined as presence of both low muscle mass and low muscle function. Suicidal ideation was assessed using the Beck Scale for Suicide Ideation. We found no differences in body composition measures between subjects with suicidal ideation and those without. In the logistic regression analyses, there were no significant relationships for suicidal ideation according to body composition measures, including BMI, WC, WHR, WHtR, and body fat percentage in both sexes. After adjusting for age, smoking status, alcohol drinking, regular exercise, medical comorbidities, monthly income, education level, and presence of depressive symptoms, the odds ratio (OR) of suicidal ideation was higher in elderly men with sarcopenia compared to those without, whereas no significant relationships were observed in elderly women (OR 8.28, 95% confidence interval [CI] 1.20-61.34 in men; OR 0.79, 95% CI 0.07-8.43 in women). Sarcopenia is closely associated with an increased risk of suicidal ideation in elderly men.

    The swaying and postural instability frequently seen in elderly subjects had not been analyzed quantitatively in detail until the introduction of computerized posturography. In order to assess the changes of body sway with aging, we performed computerized posturography in 144 subjects (51 men and 93 women, between the ages of 22 and 88 years) without specific neurological or metabolic disorders. The total and timed track length of the center of gravity, reflecting the distance of sway, increased with advancing age, with a highly significant positive correlation, without marked sex differences. The total area covered by the track of the center of gravity (expressing the extent of sway) also showed a similar tendency. Track density per unit area, expressing the efficiency of postural control, in contrast, decreased with age, showing a significant negative correlation with age, but only when the subjects had their eyes open; this decrease did not occur when they had their eyes closed. The Romberg ratio, an index of exacerbation of sway on eye closure, showed little change with a tendency for slight alleviation of sway and improvement in the efficiency of its control. Computerized posturography appears to be a useful tool with which to analyze the mechanism of swaying associated with old age.

  8. Body growth considerations in age-specific dosimetry. Final report

    Eckerman, K.F.

    1993-09-30

    This report describes the manner in which the age-specific dosimetric calculations of the International Commission on Radiological Protection (ICRP) addressed changes in organ size that occur with age. The approach involves an interpolation of dosimetric information derived for six reference individuals using the inverse of the total body mass as the interpolation variable. An alternative formulation is investigated that employs a functional representation of the organ mass as a function of age in conjunction with an explicit formulation of the dosimetric factors in terms of organ mass. Using an exponential-logistic growth function as suggested by Walker, this report demonstrates, through application to the dosimetry of radioiodines in the thyroid, that the alternative formulation can be formulated and implemented. Although either approach provides a workable basis for age-specific dosimetry, it is clear that the functional representation of organ growth has some attractive features. However, without question, the major difficulty is the quality and quantity of data available to address the age- and gender-specific parameters in the dosimetric formulations.

    2012-01-01

    Background: Menarche, a milestone in the reproductive life span of a woman, is influenced by several genetics and environmental factors. There is no consensus regarding the impact of body mass index (BMI) and lipid profiles on the age of menarche, as the results of various studies demonstrate. Objective: To investigate the correlation between age of menarche and BMI/lipoprotein profile in a community sample of Iranian girls. Materials and Methods: In the study, 370 girls, aged 10-16 years, who began their menarche within six months prior to the study, were recruited from the Tehran Lipid and Glucose Study (TLGS) population. Information was documented regarding their body composition, including height, weight, BMI, waist and hip circumference were collected and their lipid profiles were assessed after a 12-hour fast. Results: In this study, the mean±SD of age of menarche and BMI were 12.6±1.1 years and 21.7±3.9 kg/m2, respectively. There were statistically significant relationships between age of menarche and height, BMI, waist circumference, and the maternal educational level. The relationship between age of menarche and the weight and lipid profiles of subjects was not statistically significant. Conclusion: Age at menarche is not influenced by lipid profiles but it is influenced by BMI. PMID:25246895

    1988-11-01

    Dual photon absorptiometry using /sup 153/Gd in a whole-body scanner was used to measure lean body mass (LBM) in 51 newborn infants. LBM% decreased exponentially with increasing gestational age in both small for gestational age (SGA) and appropriate for gestational age (AGA) infants. In preterm SGA and AGA infants LBM was 104% and 103%, respectively, indicating that no fat was detectable. In term SGA infants LBM was 98%, which corresponded to 48 gm fat on average, and in term AGA infants LBM was 87%, which corresponded to 452 gm fat on average. The LBM%, ponderal index, and skinfold thickness were significantly different between AGA and SGA infants. Infants with clinical signs of intrauterine wastage had significantly higher LBM% than did infants without signs of weight loss. Our results on LBM% by dual photon absorptiometry agree with earlier dissection data; the clinically applicable methods of (1) height combined with weight (i.e., ponderal index), (2) skinfold thickness, and (3) scoring by clinical observations are useful for the estimation of lack of fat as an indicator of intrauterine growth retardation.

    2014-01-01

    Our aim was to investigate whether the duration of breastfeeding, at all or exclusively, is associated with educational achievement at age 5. We used data from a prospective, population-based UK cohort study, the Millennium Cohort Study (MCS). 5489 children from White ethnic background born at term in 2000-2001, attending school in England in 2006, were included in our analyses. Educational achievement was measured using the Foundation Stage Profile (FSP), a statutory assessment undertaken by teachers at the end of the child's first school year. Breastfeeding duration was ascertained from interviews with the mother when the child was 9 months old. We used modified Poisson's regression to model the association of breastfeeding duration with having reached a good level of achievement overall (≥78 overall points and ≥6 in 'personal, social and emotional development' and 'communication, language and literacy' points) and in specific areas (≥6 points) of development. Children who had been breastfed for up to 2 months were more likely to have reached a good level of overall achievement [adjusted rate ratio (RR): 1.09, 95% confidence interval (CI): 1.01, 1.19] than never breastfed children. This association was more marked in children breastfed for 2-4 months (adjusted RR: 1.17, 95% CI: 1.07, 1.29) and in those breastfed for longer than 4 months (adjusted RR: 1.16, 95% CI: 1.07, 1.26). The associations of exclusive breastfeeding with the educational achievement were similar. Our findings suggest that longer duration of breastfeeding, at all or exclusively, is associated with better educational achievement at age 5.

    Body dissatisfaction can be significantly detrimental to wellbeing. Little is known about older adults' body image, despite the fact that ageing causes unique bodily changes and that sociocultural pressures to resist these changes abound. We conducted six focus groups with a UK community sample of White British and South Asian older adults aged 65-92 years. Thematic analysis highlighted four themes: appearance indicates capability and identity; physical ability trumps appearance; felt pressures to age 'gracefully' while resisting appearance changes; and gender and cultural differences. These findings suggest that older adults' body image can have important implications for their wellbeing and merits researchers' attention.

    Aging causes various changes in body composition, which are critical implications for health and physical functioning in aging adults. The aim of this study was to explore the body composition outcomes of a qigong intervention among community-dwelling aging adults. This was a quasi-experimental study in which 90 participants were recruited. Forty-eight participants (experimental group) attended a 30-min qigong program 3 times per week for 12 weeks, whereas 42 participants (control group) continued performing their usual daily activities. The experimental group achieved a greater reduction in the fat mass percentage at the posttest, and exhibited increased fat-free mass, lean body mass percentage, and lean body mass to fat mass ratio compared with the controls. No difference between the two groups in body mass index, fat mass, and lean body mass was observed. These results indicated that the qigong intervention showed beneficial outcomes of body composition among community-dwelling aging adults.

  12. Parents' education and child body weight in France: The trajectory of the gradient in the early years.

    PubMed

    Apouey, Bénédicte H; Geoffard, Pierre-Yves

    2016-03-01

    This paper explores the relationship between parental education and offspring body weight in France. Using two large datasets spanning the 1991-2010 period, we examine the existence of inequalities in maternal and paternal education and reported child body weight measures, as well as their evolution across childhood. Our empirical specification is flexible and allows this evolution to be non-monotonic. Significant inequalities are observed for both parents' education--maternal (respectively paternal) high education is associated with a 7.20 (resp. 7.10) percentage points decrease in the probability that the child is reported to be overweight or obese, on average for children of all ages. The gradient with respect to parents' education follows an inverted U-shape across childhood, meaning that the association between parental education and child body weight widens from birth to age 8, and narrows afterward. Specifically, maternal high education is correlated with a 5.30 percentage points decrease in the probability that the child is reported to be overweight or obese at age 2, but a 9.62 percentage points decrease at age 8, and a 1.25 percentage point decrease at age 17. The figures for paternal high education are respectively 5.87, 9.11, and 4.52. This pattern seems robust, since it is found in the two datasets, when alternative variables for parental education and reported child body weight are employed, and when controls for potential confounding factors are included. The findings for the trajectory of the income gradient corroborate those of the education gradient. The results may be explained by an equalization in actual body weight across socioeconomic groups during youth, or by changes in reporting styles of height and weight.

    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

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.

    Despite many body changes that accompany the aging process, the extant research is limited on middle age and older adults' body image experiences. The purpose of the present study was to explore how body image is represented for middle age and older adult women. Using thematic analysis, 10 women over the age of 55 were interviewed within an exercise context. The following themes were found: body dissatisfaction, body satisfaction despite ageist stereotypes, neutral body image within cohort, and positive body image characteristics. Negative and positive body images were experienced simultaneously, with neutral experiences expressed as low levels of dissatisfaction. This supports the contention that negative and positive body images exist on separate continuums and neutral body image is likely on the same continuum as negative body image. Programs that foster a social support network to reduce negative body image and improve positive body image in older female populations are needed.

    Introduction Without dissection of cadavers teaching and learning of anatomy is nearly difficult; there remains a gap between the practical knowledge and the gathered theoretical knowledge. But there is a scarcity in the availability of the donated bodies for the sake of medical education. On the other hand a large number of people in our country are in waiting list for organ transplantation which could be overcome by deceased organ donation. Aim Aim of the study was to evaluate the awareness regarding body donation after death. Materials and Methods A cross-sectional study was conducted among medical students, engineering students and doctors in Indian population. Total 300 participants were answered the questionnaire providing information about the knowledge and attitude towards body and organ donation. Result 46.33% of entire study group had strongly positive attitude about cadaveric organ donation and 17% had no idea about this. 18% of total participants were unwilling for body donation after death. Conclusion The present study has been done elaborately to find out the different barriers for body or organ donation. It is clear from the study that though there is high level of awareness, nobody has filled up the pledge form till now. It indicates that there is a gap between the knowledge and motivation for organ and body donation after death which has to be overcome by proper guidance and education. Media and other voluntary organisations could take an important role for this purpose. PMID:26266106

    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.

    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.

    The purpose of this study was to further analyze the effects of education on cognitive decline during normal aging. An 806-subject sample was taken from five different Mexican regions. Participants ranged in age from 16 to 85 years. Subjects were grouped into four educational levels: illiterate, 1-4, 5-9, and 10 or more years of education, and four age ranges: 16-30, 31-50, 51-65, and 66-85 years. A brief neuropsychological test battery (NEUROPSI), standardized and normalized in Spanish, was administered. The NEUROPSI test battery includes assessment of orientation, attention, memory, language, visuoperceptual abilities, motor skills, and executive functions. In general, test scores were strongly associated with level of educational, and differences among age groups were smaller than differences among education groups. However, there was an interaction between age and education such as that among illiterate individuals scores of participants 31-50 years old were higher than scores of participants 16-30 years old for over 50% of the tests. Different patterns of interaction among educational groups were distinguished. It was concluded that: (a) The course of life-span changes in cognition are affected by education. Among individuals with a low level of education, best neuropsychological test performance is observed at an older age than among higher-educated subjects; and (b) there is not a single relationship between age-related cognitive decline and education, but different patterns may be found, depending upon the specific cognitive domain.

    Children, and in particular young children under the age of three, are the most vulnerable for aspiration and ingestion of foreign bodies (FBs). The Red Cross War Memorial Children’s Hospital in Cape Town is the only children’s hospital in South Africa and is unique in having a dedicated trauma unit for children under the age of 13 as part of its institution. Core activities of Childsafe South Africa (CSA), located at the hospital, are data accumulation and interpretation, development of educational programmes, health inculcation and advising in legislation involving child health. To achieve this task, CSA works in close co-operation with government, industry, non-governmental and community predicated organisations, community groups and individuals. A database of all children treated for trauma at CSA has been maintained since 1991; it currently contains detailed information of over 170,000 injuries in children under the age of 13. This review consists of a literature review combined with data from our database and aims to provide information on our experiences with tracheobronchial aspiration of FBs in children. PMID:28149578

    Fitness and education may protect against cognitive impairments in aging. They may also counteract age-related structural changes within the brain. Here we analyzed volumetric differences in cerebrospinal fluid and gray and white matter, along with neuropsychological data, in adults differing in age, fitness, and education. Cognitive performance was correlated with fitness and education. Voxel-based morphometry was used for a whole-brain analysis of structural magnetic resonance images. We found age-related losses in gray and white matter in medial-temporal, parietal, and frontal areas. As in previous work, fitness within the old correlated with preserved gray matter in the same areas. In contrast, higher education predicted preserved white matter in inferior frontal areas. These data suggest that fitness and education may both be predictive of preserved cognitive function in aging through separable effects on brain structure. PMID:18627534

    The objective was to identify maternal variables that could be used as predictors of the child's body mass index (BMI). We considered the following variables: (a) socio-demographic (age, education, occupation, marital status and family income); (b) anthropometric (BMI); and (c) upbringing strategies (monitoring and limits for eating habits, monitoring and sedentary behavior limits, discipline and control in feeding. A predictive correlational study was carried out with 537 dyads (mother-child). Children enrolled in 4 public schools (2 for pre-school children and 2 for primary school children) were selected for probabilistic, random sampling. The mothers answered the Feeding and Activity Upbringing Strategies Scale, giving socio-demographic information and the dyads' weight and height was measured. The data were analyzed for correlations and path analysis. It was found that the average age of mothers was 34.25 years (SD=6.91), with 12.40 years of education (SD=3.36), 53.3% mentioned that they were housewives and 46.7% had a paid job outside of the home; 38.5% showed pre-OB and 27.3% some degree of OB. The child's average age was 7.26 years (SD=2.46), and 3.2% showed low weight, 59.6% normal weight and 37.2% OW-0B. It was found that working outside the home, having a higher maternal BMI, less control and more discipline in feeding are variables that predict higher BMI in the child. We recommend the design of interventions to reduce and treat the child's OW-OB taking into account the predictors that were found.

    Major depressive disorder (MDD) is associated with a high rate of developing serious medical comorbidities such as cardiovascular disease, stroke, dementia, osteoporosis, diabetes, and the metabolic syndrome. These are conditions that typically occur late in life, and it has been suggested that MDD may be associated with “accelerated aging.” We review several moderators and mediators that may accompany MDD and that may give rise to these comorbid medical conditions. We first review the moderating effects of psychological styles of coping, genetic predisposition, and epigenetic modifications (eg, secondary to childhood adversity). We then focus on several interlinked mediators occurring in MDD (or at least in subtypes of MDD) that may contribute to the medical comorbidity burden and to accelerated aging: limbic-hypothalamic-pituitary-adrenal axis alterations, diminution in glucocorticoid receptor function, altered glucose tolerance and insulin sensitivity, excitotoxicity, increases in intracellular calcium, oxidative stress, a proinflammatory milieu, lowered levels of “counter-regulatory” neurosteroids (such as allopregnanolone and dehydroepiandrosterone), diminished neurotrophic activity, and accelerated cell aging, manifest as alterations in telomerase activity and as shortening of telomeres, which can lead to apoptosis and cell death. In this model, MDD is characterized by a surfeit of potentially destructive mediators and an insufficiency of protective or restorative ones. These factors interact in increasing the likelihood of physical disease and of accelerated aging at the cellular level. We conclude with suggestions for novel mechanism-based therapeutics based on these mediators. PMID:21485744

    The study objectives were to determine the impact of a nationwide educational campaign on the incidence of foreign body aspiration (FBA) in Israeli children. Impressed by the alarming number of FBAs, we conducted an educational campaign through the media during 1982-1983. The campaign included television and radio broadcasts, newspaper articles and interviews, and medical educational programmes in community paediatric care centres. Questionnaires were sent to all Departments of Paediatrics in Israel. Results showed a reduction in the incidence of FBA by 35% in 1983 as compared to 1981. Re-evaluation studies conducted in 1992 showed no further reduction of FBA. CONCLUSION. Continuous and extensive educational programmes should be undertaken by the health authorities if FBA is to be prevented. Furthermore, it is important to legislate mandatory labelling of seed and nut containers with the warning that the intake of seeds is dangerous to children under 5 years of age.

    The article describes two Estonian anthropometric cross-sectional studies of 1549 ordinary schoolgirls (aged 7-18) and 46 girls, who regularly practised volleyball (aged 13-16). Data are presented on 22 basic anthropometric measurements and 6 body composition characteristics (body mass index, mean skinfold, body density, relative mass of fat by Siri, absolute mass and relative mass of subcutaneous adipose tissue). All anthropometric variables were classified into five height-weight SD classes. Schoolgirls were divided into six age groups (7-8, 9-10, 11-12, 13-14, 15-16, 17-18). Volleyballers were observed as one group as their age in SD classes did not differ significantly. The classification consisted of five categories: three height-weight concordant categories: I--small (small height, small weight), II--medium (medium height, medium weight), III large--(big height, big weight) and two height/weight discordant categories: IV--so-called pyknomorphs, V--so-called leptomorphs. To assess the differences between classes the Scheffé-test was used (alpha = 0.05). It proved likewise possible to comparatively systematize length, breadth and depth measurements, circumferences and body composition characteristics in all six age groups (7-18 years) of ordinary schoolgirls and in 13-16-year-old volleyballers as in their case the average age did not differ significantly between the classes.

    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.

    Inflammatory models of neurodegeneration suggest that higher circulating levels of inflammation can lead to cognitive decline. Despite established independent associations between greater body mass, increased inflammation, and cognitive decline, no prior research has explored whether markers of systemic inflammation might mediate the association between body mass and changes in cognitive functioning. To test such a model, we used two longitudinal subsamples (ns=9066; 12,561) of aging adults from the English Longitudinal Study of Ageing (ELSA) study, which included two cognitive measures components of memory and executive functioning, as well as measurements of body mass and systemic inflammation, assessed via C-reactive protein (CRP). Greater body mass was indirectly associated with declines in memory and executive functioning over 6years via relatively higher levels of CRP. Our results suggest that systemic inflammation is one biologically plausible mechanism through which differences in body mass might influence changes in cognitive functioning among aging adults.

    Introduction 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. Methods 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. Results 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). Conclusion 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.

    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

    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.

    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.

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

    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.

    The number of older adults is increasing in industrialized and in developing countries. The present community-based cross sectional work was undertaken to study the anthropometric, body composition, and blood pressure characteristics of rural-dwelling elderly adults of Asian Indian origin. A total of 300 individuals (Male = 157 and Female = 143) from the Bolpur-Sriniketan area of West Bengal, India, took part in the study. Participants were divided into four age-groups: Group I, 55-59 years (Male:Female = 55:61); Group II, 60-64 years (Male:Female = 41:33); Group III, 65-69 years (Male:Female = 27:21); Group IV, 70 years and older (Male:Female = 34:28). Anthropometric measures were taken using standard techniques. Body mass index, waist-hip ratio, and the sum of four skin folds were subsequently computed. Body composition measures, namely percentage of body fat, fat mass, fat free mass, arm muscle circumference, arm muscle area, and arm fat area, were calculated accordingly. Left-arm systolic (SBP) and diastolic blood pressures (DBP) were also measured, and mean arterial pressure was subsequently calculated. Overall observations in the study population indicate a predominance of body weights below the normal body mass index of 25 kg/m(2). More than half the subjects reported the lack of adequate sanitation facilities and education levels were generally low. Rates of smoking (65.6%) and habitual consumption of alcohol (38.9%) were high in male participants. Upon comparison across the four age groups, results revealed decreases in percent body fat, fat mass, and mid upper arm muscle circumference for Groups III and IV versus Group I for men and for Group IV versus I for women. The overall trend for both SBP and DBP was for small increases with age in men in contrast to slight decreases with age in women. Our findings of generally low body weights, detrimental age-related changes in body composition, and a number of other health-related concerns highlight

    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.

    Perception of age and health is critical in the judgement of attractiveness. The few studies conducted on the significance of apparent skin condition on human physical appearance have studied faces alone or isolated fields of images facial skin. Little is known about whether perception of the face matches that of other body parts or if body skin affects overall age and attractiveness perception when presented in combination with facial skin. We hypothesized that independent presentation of female faces, chests and arms (including hands) - cropped from a full face and upper body image - would result in significant differences in perception of age and attractiveness compared to the corresponding composite. Furthermore, we sought to investigate whether relatively young and attractive looking skin on selected, individual parts of the body affects overall perception. Digital photographs of 52 women aged 45-65 years were collected and processed to yield four derivative sets of images: One set showed the composite of all features, i.e. the face, the chest and the arms, whereas the other three were cropped carefully to show each part of the upper body described above independently. A total of 240 participants judged these faces for perceived age and attractiveness. Our results showed significant differences in perception with the chest and the arms being judged significantly younger than the face or composite image of the same women. Moreover, arms and chest images were perceived as more attractive than face and composite images. Finally, regression analysis indicated that differences between the perceived and chronological values of overall age perception could be predicted by age perception of the face and arms. These results continue to support the significance of facial age perception in assessment of a woman's age, but highlight that body skin also plays a role in overall age impression.

    2010-01-01

    Background/objectives One phenomenon of skin aging is loss of cutaneous elasticity. Measurement of cutaneous resonance running time (CRRT) is a method to assess skin elasticity. Yet, information regarding directional changes of CRRT associated with age, body sites and gender is not yet available. In the present study, we assessed whether changes in CRRT vary with age, body sites and gender in a normal Chinese population. Methods A Reviscometer was used to measure CRRTs in various directions on the left dorsal hand, the forehead and the left canthus of 806 normal Chinese volunteers, aged 2.5-94 years. Results With aging, CRRTs decreased in all directions on the hand, the forehead, and the canthus. A more dramatic reduction of CRRTs on the forehead and the canthus were observed at both the 2–8 and 3–9 o’clock directions. CRRTs in males aged 11– 20 years old were longer than those in females at some directions on all three body sites. Females between 21 and 40 years old showed longer CRRTs than males in some directions of the hand. There were no gender differences in subjects aged 0–10 (except on the canthus) and over 81 years old. Conclusion CRRTs vary with age, body sites and gender. PMID:21039906

  16. Nursing education and the nuclear age

    SciTech Connect

    1989-05-01

    As reflected in the nursing literature, nurses have only recently begun discussing professional responsibilities for avoidance of nuclear war. The literature of the 1950s and 1960s focused on issues of civil defense. The 1970s were mostly silent, but with the onset of the 1980s a few articles identified the need for the nursing profession to recognize the importance of nuclear war prevention. The responsibility of nursing education for including content about nuclear issues has not been discussed in the professional literature. The author surveyed baccalaureate programs of nursing education to determine whether this lack of discussion was reflected in nursing curricula. Responses indicated that the literature does not adequately reflect the level of activity and interest occurring within nursing education about nuclear issues. Nevertheless, because there is so little discussion in the professional literature, an implicit message is sent that nuclear issues are not of importance and that nurses should not openly address them.24 references.

  17. 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.

  18. 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

  9. 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.

    Sparkes, Andrew C; Day, Jo

    2016-01-01

    The processes involved in the transition from crime to desistance, in relation to how those involved in criminal activity give meaning to their experiences of aging over time, has received little empirical scrutiny in the criminological literature. In this article, we unpack and flesh out the multiple meanings of age by drawing on a life story study of desistance from crime. Our analysis foregrounds the following key themes and the interactive parts they play in the process of desistence: general perceptions of aging (critical ages and the ambiguity of age); the significance of the aging body (crime as a young person's game, tiredness, and slowing down); age and risk assessment; and feelings of missing out and lost time with age. We conclude by suggesting that researchers into the phenomenon of desistance with an interest in maturation theory might benefit from integrating work undertaken in the sociology of embodiment and critical gerontology. A brief example of how this integration might operate is provided.

  4. The influence of body size on adult skeletal age estimation methods.

    PubMed

    Merritt, Catherine E

    2015-01-01

    Accurate age estimations are essential to archaeological and forensic analyses. However, reliability for adult skeletal age estimations is poor, especially for individuals over the age of 40 years. This is the first study to show that body size influences skeletal age estimation. The İşcan et al., Lovejoy et al., Buckberry and Chamberlain, and Suchey-Brooks age methods were tested on 764 adult skeletons from the Hamann-Todd and William Bass Collections. Statures ranged from 1.30 to 1.93 m and body masses ranged from 24.0 to 99.8 kg. Transition analysis was used to evaluate the differences in the age estimations. For all four methods, the smallest individuals have the lowest ages at transition and the largest individuals have the highest ages at transition. Short and light individuals are consistently underaged, while tall and heavy individuals are consistently overaged. When femoral length and femoral head diameter are compared with the log-age model, results show the same trend as the known stature and body mass measurements. The skeletal remains of underweight individuals have fewer age markers while those of obese individuals have increased surface degeneration and osteophytic lipping. Tissue type and mechanical loading have been shown to affect bone turnover rates, and may explain the differing patterns of skeletal aging. From an archaeological perspective, the underaging of light, short individuals suggests the need to revisit the current research consensus on the young mortality rates of past populations. From a forensic perspective, understanding the influence of body size will impact efforts to identify victims of mass disasters, genocides, and homicides.

    2009-01-01

    The qBody project is a qualitative research study that aims to understand how students with "queer bodies" are impacted by heterosexism, transphobia, ableism, and fat phobia in Canadian physical education. Approximately 40 adults, who self-identified as a sexual minority, gender minority, having a physical disability, and/or socially undervalued body shape/size were interviewed about how physical education impacts their participation in, and alienation from, physical cultures later in life. This article situates the theoretical approach of the qBody project within the historical development of research into homophobia and lesbians in physical education and sport. Specifically, the article traces how postmodern theories of embodiment are transforming "lesbian studies in sport" into multidimensional studies of marginalization and normalcy-an area that might be referred to as "postmodern body studies."

    2005-01-01

    The association of age and weekly swim training distance with body water, lean tissue, fat mass and regional adiposity was examined in 27 male masters swimmers. Subjects ranged in age from 25.3 to 73.1 years (mean age = 47.7 ± 11.1 years). Weekly swim distances, estimated from self-reported swim logs, were from 3 400 to 17 500 m and averaged 10 016 ± 4 223 m. Total body water (TBW), and extracellular water (ECW) were predicted from multi-frequency bioelectrical impedance analysis and intracellular water was estimated by difference. Lean soft tissue, bone mineral content, fat mass, and percent body fat were estimated from dual-energy X-ray absorptiometry. Measures of skinfold thickness, waist circumference, and abdominal sagittal diameter provided an indication of regional adiposity. Total body water, ECW, and ICW mean values (ranges) were as follows: 47.4 ± 4.6 L (37.9-56.9 L), 19.6 ± 1.8 L., (16.4-24.8 L), and 27.8 ± 3.2 L (21.5-34.4 L). Mean percent body fat levels were 21.9 ± 6.6% and ranged from 10.3 to 34.9%. Age was negatively associated with ICW (p = 0.02) and with the ICW/TBW ratio (p = 0.00). Multiple-linear regression analysis backward method suggested that both lean tissue and fat mass were predictors of ICW although the association with fat mass did not reach statistical significance (p = 0.00 and p = 0.06 for lean and fat mass respectively). There was a tendency for greater lower abdominal thickness with increasing age (p = 0.08), but no other associations were observed between age or with swimming and body composition variables. Changes in ICW and the ration of ICW to TBW appeared to be the strongest marker of aging in this group of adult male competitive swimmers. Key PointsSubject age was negatively associated with the volume of intracellular water and with the intracellular-to-total body water ratio.There was a trend for age to be positively related to lower abdominal thickness.Weekly swim training distance was not associated with body water

Objectives: 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. Patients and Methods: 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. Results: 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. Conclusions: 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. PMID:26734482

    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.

    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

    Problematic eating behaviors during childhood may lead to positive energy balance and obesity. Therefore, this study aims to investigate the association of eating behaviors with nutritional status and body composition in Malaysian children aged 7 to 12 years. A total of 1782 primary schoolchildren were randomly recruited from 6 regions in Malaysia. The multidimensional Children's Eating Behaviour Questionnaire (CEBQ) was reported by parents to determine the 8 different dimensions of eating styles among children. Body mass index (BMI), BMI-for-age Z-score, waist circumference, and body fat percentage were assessed. Linear regression analyses revealed that both food responsiveness and desire to drink subscales were positively associated with a child's body adiposity, whereas satiety responsiveness, slowness in eating, and emotional undereating subscales were negatively associated with adiposity (all P < .05). A multidimensional eating style approach based on the CEBQ is needed to promote healthy eating behaviors in order to prevent excessive weight gain and obesity problems among Malaysian children.

    Although many have studied the association between educational attainment and obesity, studies to date have not fully examined prior common causes and possible interactions by race/ethnicity or gender. It is also not clear if the relationship between actual educational attainment and obesity is independent of the role of aspired educational attainment or expected educational attainment. The authors use generalized linear log link models to examine the association between educational attainment at age 25 and obesity (BMI≥30) at age 40 in the USA’s National Longitudinal Survey of Youth 1979 cohort, adjusting for demographics, confounders, and mediators. Race/ethnicity but not gender interacted with educational attainment. In a complete case analysis, after adjusting for socioeconomic covariates from childhood, adolescence, and adulthood, among whites only, college graduates were less likely than high school graduates to be obese (RR= 0.69, 95%CI: 0.57, 0.83). The risk ratio remained similar in two sensitivity analyses when the authors adjusted for educational aspirations and educational expectations and analyzed a multiply imputed dataset to address missingness. This more nuanced understanding of the role of education after controlling for a thorough set of confounders and mediators helps advance the study of social determinants of health and risk factors for obesity.

    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.

    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.

    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.

  18. 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.

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

    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.

    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.

    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.

    Total body levels of nitrogen were measured by prompt-gamma neutron activation analysis in 136 healthy adults in the general population (age 20 to 80 years), in 55 cancer patients, and in 20 obese subjects. In order to evaluate the TBN values for the patients, it was necessary to normalize the data for possible differences due to body habitus. This normalization was defined as the ratio of the measured nitrogen level to a predicted nitrogen level derived from the normal population. The parameters of sex, age, height, weight, and fat were used to calculate expected normal values of nitrogen. For the cancer patients, an average TBN deficit of less than 10% was observed. Individual patients, however, showed deviations from the TBN/sub p/ value as large as 28%. For obese patients, the TBN values were normal to slightly high. When adjusted for body size, the deficit of TBN in the cancer patients was approximately half that observd for TBK.

    A uranium-lead zircon age for a volcanic ash interstratified with fossil-bearing, shallow marine siliciclastic rocks in the Zimnie Gory section of the White Sea region indicates that a diverse assemblage of body and trace fossils occurred before 555.3 +/- 0.3 million years ago. This age is a minimum for the oldest well-documented triploblastic bilaterian Kimberella. It also makes co-occurring trace fossils the oldest that are reliably dated. This determination of age implies that there is no simple relation between Ediacaran diversity and the carbon isotopic composition of Neoproterozoic seawater.

    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.

    1999-11-01

    Heritabilities (h2) of body mass at different ages and seasons were estimated using offspring-mother regression and restricted maximum likelihood (REML) methods for bighorn sheep on Ram Mountain, Alberta. Both methods resulted in similar estimates of h2 for adults, but for lambs and yearlings heritability was underestimated by offspring-mother regression relative to REML, possibly because of higher maternal-effects bias for offspring-mother regression. Heritabilities of body mass in bighorn were similar to published estimates for domestic sheep. Heritability estimated by offspring-mother regression increased after 2 years of age. The REML method suggested that heritability was moderate for lambs and yearlings, very low at 2 years of age, and increased afterwards. The increase in heritability with age was attributed to declining negative maternal effects. Very low h2 estimates at 2 years of age, obtained with both methods, appeared to be caused by a combination of high environmental variance and very low genetic variance. Body mass of bighorn sheep has a pronounced seasonal cycle, and h2 was lower in June than in September for 2-year-olds and older sheep, and associated with both lower VA and higher VE in spring.

    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.

  13. Older Single Gay Men's Body Talk: Resisting and Rigidifying the Aging Discourse in the Gay Community.

    2017-01-01

    Previous research saw older gay men as subject to structural marginalization of ageism but yet possessing agency to interpret aging in diverse ways. I move beyond this duality, drawing on the theory of defensive othering to understand how older gay men live with the aging discourse in the gay community. Informed by grounded theory, I analyzed interviews with 25 self-identified single gay men aged 50 or above in England inductively. It emerged that many older gay men found it difficult to escape the discourse that marginalizes the aging body. Even when they argued they were the exception and "looked good," they were discursively producing a two-tier system: they themselves as the "good older gay men," as opposed to the other "bad older gay men," who "had given up." Such a defensive othering tactic seemingly allowed them to resist age norms from applying to them personally, but unintentionally reinforced an ageist discourse.

    GH has a significant impact on body composition due to distinct anabolic and catabolic effects on lean and fat mass, respectively. Several studies have assessed body composition in mice expressing a GH transgene. Whereas all studies report enhanced growth of transgenic mice as compared with littermate controls, there are inconsistencies in terms of the relative proportion of lean mass to fat mass in these animals. The purpose of this study was to characterize the accumulation of adipose and lean mass with age and according to gender in a bovine (b) GH transgenic mouse line. Weight and body composition measurements were assessed in male and female bGH mice with corresponding littermate controls in the C57BL/6J genetic background. Body composition measurements began at 6 wk and continued through 1 yr of age. At the conclusion of the study, tissue weights were determined and triglyceride content was quantified in liver and kidney. Although body weights for bGH mice were significantly greater than their corresponding littermate controls at all time points, body composition measurements revealed an unexpected transition midway through analyses. That is, younger bGH mice had relatively more fat mass than nontransgenic littermates, whereas bGH mice became significantly leaner than controls by 4 months in males and 6 months in females. These results reveal the importance in timing and gender when conducting studies related to body composition or lean and fat tissue in GH transgenic mice or in other genetically manipulated mouse strains in which body composition may be impacted.

    Purpose To define the prevalence of distorted body image in 10–24-year-old Koreans and determine its relationship with sex, age, body weight status, and disordered eating behaviors. Methods A total of 3,227 young Koreans were recruited from elementary, middle, and high schools, as well as from universities. The participants completed a self-reported questionnaire on body image, eating behaviors (Eating Attitude Test-26), and body weight status. Results The prevalence of a distorted body image in males was 49.7% and that in females was 51.2%. Distorted body image was more frequent in adolescents (age, 10–17 years) than in young adults (age, 18–24 years). The highest prevalence (55.3%) was reported in female elementary school students (age, 10–12 years). Distorted body image was associated with disordered eating behaviors and abnormal body weight status. Conclusion These results suggest that distorted body image is a public health problem, given its high frequency in young Koreans, and that it is associated with abnormal body weight status and disordered eating behaviors.

  2. 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.

    Functional imaging studies have shown that elderly individuals activate widespread additional brain networks, compared to young subjects, when performing motor tasks. However, the parameters that effect this unique neural activation, including the spatial distribution of this activation across hemispheres, are still largely unknown. Here, we examined the effect of task complexity and body side on activation differences between older and younger adults while performing cyclical flexion-extension movements of the ipsilateral hand and foot. In particular, easy (isodirectional) and more difficult (non-isodirectional) coordination patterns were performed with either the left or right body side at a self-selected, comfortable rate. Even in the absence of imposed pacing the older group activated a larger brain network, suggestive of increased attentional deployment for monitoring the spatial relationships between the simultaneously moving segments and enhanced sensory processing and integration. Evidence of age-dependent underactivation was also found in contralateral M1, SMA and bilateral putamen, possibly reflecting a functional decline of the basal ganglia-mesial cortex pathway in the older group. An ANOVA model revealed significant main effects of task complexity and body side. However the interaction of these factors with age did not reach significance. Consequently, we conclude that under self-paced conditions, task complexity and body side did not have a modulatory effect on age-related brain activation.

    The aim of the study was to examine the effect of socioeconomic status (SES), age, weight and gender on the body image and weight control practices of children and adolescents, and to investigate whether health education about weight issues should target low socioeconomic groups. The study participants were a randomly selected group of school children who completed a questionnaire, and had their height and weight measured. Participants (n = 1131) were aged 6-19 years from 12 schools in New South Wales. SES, age, gender, body weight, body image, skipping breakfast, physical self-esteem, attempts to lose or gain weight, and dietary and weight control advice received from others were examined. Log-linear, chi 2 and MANOVA analyses were used to determine interactions between variables. Low SES children were more likely to be overweight, to skip breakfast, to perceive themselves as 'too thin', to be trying to gain weight and less likely to receive dietary or weight control advice. Physical self-esteem was lowest among overweight girls of middle/upper SES and greatest among boys of low SES, despite the latter being more likely to be overweight. Being overweight does not appear to adversely affect the physical self-esteem of children of low SES, particularly boys. Health educators should examine these issues with young people to help make health education and nutrition education most relevant and appropriate.

    Study design Systematic review. Objective To systematically review evidence on aging of the body systems after spinal cord injury (SCI). Setting Toronto, Ontario and Vancouver, British Columbia, Canada. Methods Electronic databases (MEDLINE/PubMed, CINAHL, EMBASE, and PsycINFO), were searched for studies published between 1980 and 2009. The search was augmented by reviewing the reference lists of relevant papers. Non-intervention studies that were longitudinal or cross-sectional with able-bodied (AB) controls that were at minimum matched on chronological age were included for review. Levels of evidence were assigned to the study design using a modified Sackett scale. Results Of the 74 studies selected for inclusion, 16 were longitudinal in design. The hypothesis that SCI represents a model for premature aging is supported by a large proportion of level 5 evidence for the cardiovascular and endocrine systems, level 2, 4 and 5 evidence for the musculoskeletal system, and limited level 5 evidence for the immune system. Only a few level 4 and 5 studies for the respiratory system were found. The evidence on the genitourinary system, gastrointestinal system, and for skin and subcutaneous tissues provide level 4 and 5 evidence that premature aging may not be occurring. The evidence on the nervous system does not provide evidence of premature aging as a result of SCI. Conclusions Premature aging appears to occur in some systems after SCI. Additional longitudinal studies are required to confirm these findings. Sponsorship Rick Hansen Institute; Ontario Neurotrauma Foundation. PMID:21151191

    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. PMID:25896951

    A lack of satisfaction with one's body is common among women with obesity, often prompting unhealthy "dieting." Beyond typically slow improvements in weight and body composition, behavioral factors might also affect change in body satisfaction. Age and race/ethnicity (African American vs. White) might moderate such change. Obese women (N = 246; M(age) = 43 years; M BMI = 39 kg/m(2)) initiating a 6-month cognitive-behaviorally based physical activity and nutrition treatment were assessed on possible predictors of body satisfaction change. At baseline, African American and younger women had significantly higher body satisfaction. The treatment was associated with significant within-group improvements in mood, health behaviors (physical activity and fruit/vegetable intake), and body composition (waist circumference). A multiple regression analysis indicated that mood, health behavior, and body composition changes explained a significant 27% of the variance in body satisfaction change. Of these predictors, changes in mood (β = -.36, p < .001) and health behaviors (β = .18, p = .01) made significant, unique contributions to the variance in change in body satisfaction that was accounted for, while only the measure of actual physiological change (body composition) did not. Neither age nor race/ethnicity was a significant moderator when each was entered separately into the multiple regression equation. Practical implications for leveraging manageable changes in behavioral factors for improving body satisfaction were discussed.

    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. PMID:28212335

    Sex and age are the major determinants of serum levels of dehydroepiandrosterone sulfate (DHEA-S): they are about twice in men than in women and show a progressive reduction from the end of the puberty to aging in both sexes. It has been reported that DHEA-S levels are also negatively influenced by insulin. Moreover, DHEA-S levels reduction has been associated to increased risk for cardiovascular disease, which connotes hyperinsulinemic states, such as obesity. We have evaluated serum levels of DHEA-S and insulin as function of age and body mass index (BMI) in 376 adult women (age 18.1-89.6 yrs, median 42.2; BMI 15.7-57.8 kg/m2, median 32.7) by multiple regression and piecewise regression analysis. Insulin levels positively associated to BMI (p=0.000002) and DHEA-S levels negatively associated with age (p=0.000001). Considering the whole population, DHEA-S levels were related positively with BMI (p=0.0013) independently of age. DHEA-S were also directly related to insulin levels independently of age (p=0.042), but this association disappeared after correction for BMI. Piecewise regression analysis did not reveal a threshold level for the increase of BMI (p=0.0004). Interestingly, DHEA-S levels and BMI were positively associated before but not after menopause. Taking into account only obese population, (no.=143, age 18.7-67.3 yrs, mean 39.0, median 39.4) DHEA-S levels were again related negatively with age and positively with BMI, while were unrelated with waist to hip ratio (p=0.391). Our data show that increasing body mass and insulin secretion is not associated to DHEA-S reduction in women. This evidence suggests that DHEA-S is unlikely implicated in the pathogenesis of cardiovascular disease in obese women.

    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

    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.

    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.

    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 paper was to establish whether the influence of socioeconomic factors on BMI and the prevalence of underweight and overweight changes with age. The data were obtained from 1008 schoolgirls aged 16-18 years for whom earlier data on weight and height were available. Their height and body mass were measured and their BMIs calculated. Height and weight in early life were assessed by medical records review. The girls were measured by trained school nurses at 7, 9, 14 years of age. Socioeconomic differences in BMI were found to increase with age. Parents' higher education and urban environment were associated with smaller BMI gain between the ages of 7 and 18 years. Among subjects whose mother and/or father had higher education the prevalence of underweight increased with age, and in other groups it remained at a similar level. In the younger age categories (7- and 9-year-olds) underweight was less frequent in subjects from towns than those from rural areas, while in the older categories (14, 16-18 years of age) the opposite tendency was found. As subjects grew up, there was a decline in the prevalence of overweight and obesity in all groups. Parental education and place of residence seem to influence weight status in a different way in childhood than during adolescence.

    Early age thermal conditioning (TC) durably improves resistance of broilers to heat stress and reduces body temperature (Tb). Three experiments on broiler chicks were conducted to evaluate the effects of TC at 5 d of age on Tb variation measured by thermometer between 4 and 7 d of age, under a tropical environment. Because manipulation of chickens to measure Tb with a thermometer may increase Tb, a preliminary experiment on 13 3-to-4-wk-old male broilers compared Tb measured by telemetry to Tb measured in the terminal colon during three successive periods at 22, 33, and 22 degrees C. During heat exposure, Tb rapidly increased by 0.9 degrees C and plateaued over 24 h. During the last period, seven of the broilers rapidly reduced Tb to a plateau lower than the initial Tb, although six broilers exhibited more variable Tb. Measurement by thermometer underestimated on average core Tb by 0.28 degrees C at 22 degrees C and by 0.57 degrees C at 33 degrees C, whereas Tb recorded by telemetry was not affected by manipulation of the chickens. TC reduced Tb 24 h later in the three experiments. Compared to unexposed control chicks (N), 12 h of TC at 40 degrees C did not significantly reduce Tb at 7 d of age, although 24 h did. TC at 38 and 40 degrees C over 24 h significantly reduced Tb variation from 4 to 7 d of age compared to N chicks, whereas 36 degrees C did not. Withdrawing feed from the chicks for 2 h prior to measurement did not significantly reduce Tb at 4 and 7 d of age, but Tb reduction due to TC was greater in fed chicks (0.28 degrees C) than in chicks without feed (0.05 degrees C). Early age thermal conditioning at 38 to 40 degrees C at 5 d of age for 24 h reduced body temperature of 7-d-old male broilers.

    BACKGROUND Brazil has witnessed dramatic changes in its fertility patterns in recent decades. The decline to below-replacement fertility has been accompanied by increases in the proportion of children born to young mothers. Yet we know little about the well-being of children born to young mothers in Brazil. OBJECTIVE and METHODS Using data from the 2006 Pesquisa Nacional de Demografia e Saúde and a quasi-natural experimental approach, this study examines the implications of maternal age at first birth for the education of Brazilian adolescents. RESULTS We find that being born to a young mother is associated with educational disadvantages in adolescence, but that these disadvantages are attenuated once we account for mothers’ selection into early childbearing. We also find that, in southern Brazil, adolescents born to young mothers have poorer educational outcomes compared with their peers born to older mothers, but that in northern Brazil no such disparities exist. CONCLUSIONS Adolescent educational disadvantages associated with being born to a young mother are not an artifact of selectivity, at least in southern Brazil.

    OBJECTIVE--To examine the association between self reported alcohol intake and subsequent mortality from all causes and if the effect of alcohol intake on the risk of death is modified by sex, age, body mass index, and smoking. DESIGN--Prospective population study with baseline assessment of alcohol and tobacco consumption and body mass index, and 10-12 years' follow up of mortality. SETTING--Copenhagen city heart study, Denmark. SUBJECTS--7234 women and 6051 men aged 30-79 years. MAIN OUTCOME MEASURE--Number and time of deaths from 1976 to 1988. RESULTS--A total of 2229 people died, 1398 being men. A U shaped curve described the relation between alcohol intake and mortality. The lowest risk was observed at one to six alcoholic beverages a week (relative risk set at 1). Abstainers had a relative risk of 1.37 (95% confidence interval 1.20 to 1.56) whereas those drinking more than 70 beverages a week had a relative risk of 2.29 (1.75 to 3.00). Among the drinkers, the risk was significantly increased only among those drinking more than 42 beverages a week. Sex, age, body mass index, and smoking did not significantly modify the risk function. The risk among heavy drinkers was slightly reduced when smoking was controlled for. The risk function was similar in the first and second period of six years of observation. CONCLUSION--Alcohol intake showed a U shaped relation to mortality with the nadir at one to six beverages a week. The risk function was not modified by sex, age, body mass index, or smoking and remained stable over 12 years. PMID:8124118

    Endurance-trained older men have a higher proportion of lean tissue and greater muscle cell oxidative capacity, reversing age-related trends and suggesting major changes in protein metabolism. In this study, protein turnover was determined in 6 middle-aged (52+/-1 yr) men who were well trained (VO/sub 2/ max 55.2+/-5.0 ml O/sub 2//kg.min) and lean (body fat 18.9+/-2.8%, muscle mass 36.6+/-0.6%). The maintained habitual exercise while consuming 0.6, 0.9 or 1.2 g protein/kg.day for 10-day periods. N flux was measured from /sup 15/N in urea after oral /sup 15/N-glycine administration. Myofibrillar protein breakdown was estimated from urinary 3-methyl-histidine. Dietary protein had no effect on turnover rates, even when N balance was negative. Whole body protein synthesis was 3.60+/-0.12 g/kg.day and breakdown was 3.40+/-0.14 g/kg.day for all N intakes. Whole body protein flux, synthesis and breakdown were similar to values reported for sedentary young (SY) or sedentary old (SO) men on comparable diets. 3-me-his (3.67+/-0.14 ..mu..mol/kg.day) was similar to values reported for SY but higher (p<0.01) than for SO. Myofibrillar protein breakdown per unit muscle mass (185+/-7 ..mu..mol 3-me-his/g creatinine) was higher (p<0.01) than for SY or SO. In active middle-aged men, myofibrillar proteins may account for a greater proportion of whole body protein turnover, despite an age-related reduction in muscle mass.

    (1) Background: Late preterm infants account for the majority of preterm births and are at risk of altered body composition. Because body composition modulates later health outcomes and human milk is recommended as the normal method for infant feeding, we sought to investigate whether human milk feeding in early life can modulate body composition development in late preterm infants; (2) Methods: Neonatal, anthropometric and feeding data of 284 late preterm infants were collected. Body composition was evaluated at term-corrected age by air displacement plethysmography. The effect of human milk feeding on fat-free mass and fat mass content was evaluated using multiple linear regression analysis; (3) Results: Human milk was fed to 68% of the infants. According to multiple regression analysis, being fed any human milk at discharge and at  term-corrected and being fed exclusively human milk at term-corrected age were positively associated with fat-free mass content(β = −47.9, 95% confidence interval (CI) = −95.7; −0.18; p = 0.049; β = −89.6, 95% CI = −131.5; −47.7; p < 0.0001; β = −104.1, 95% CI = −151.4; −56.7, p < 0.0001); (4) Conclusion: Human milk feeding appears to be associated with fat-free mass deposition in late preterm infants. Healthcare professionals should direct efforts toward promoting and supporting breastfeeding in these vulnerable infants. PMID:27782098

    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.

    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.

    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.

    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.

    [Purpose] The purpose of this study was to determine the effectiveness of whole-body passive vibration exercise and its differences from aerobic exercise on body composition, bone mineral density (BMD) and bone mineral content (BMC). [Methods] Obese middle-aged women (n=33 out of 45) with 34±3% body fat completed the training protocol. They were randomly assigned into diet (n=9; control group), diet plus whole-body vibration exercise (n=13; vibration group), and diet plus aerobic exercise (n=11; aerobic group) groups and we compared their body composition, BMD, and BMC before and after 9 months of training. There were no significant differences in nutrient intake among groups during the training period. [Results] Relative body fat (%) decreased significantly (p < .05) in all three groups and the exercise groups showed a greater reduction in fat mass than the diet only group. BMD in the whole body, lumbar spine, hip and forearm were not significantly different among the three groups. Total body BMC increased significantly in the vibration group throughout the first 6 months of training. [Conclusion] Results suggest that long- term vibration training when used in conjunction with a diet program is as effective as aerobic exercise with a diet program in improving body composition of obese middle-aged women without compromising BMC or BMD. Thus, it can be considered a novel and effective method for reducing body fat. PMID:27508150

    Background 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. Methods 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. Results 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%). Conclusions After considering the completeness of reporting and quality of classifying drowning deaths across countries, we conclude that drowning is a high-priority public health

  17. Frail bodies: geriatric medicine and the constitution of the fourth age.

    PubMed

    Pickard, Susan

    2014-05-01

    Clinical discourses of frailty are central both to the construction of the social category of the fourth age and to the role and identity of hospital geriatric medicine. However, the influence of such clinical discourses is not just from science to the social sphere and nor do these discourses have their source in a putative truth of the old body but emerge from an interplay between physiological facts, discourses of governmentality, productive processes associated with late modern capitalism and the professional ambitions of geriatric medicine. The article explores this interplay in the two key discourses of frailty that have emerged in the clinical literature during the past 15 years, that of the phenotype and the accumulation of deficits, respectively. Outlining the development of the discourse of senescence from its origins to the more recent emergence of a nosological category of frailty the article explores how these key discourses capture the older body according to particular sets of norms. These norms link physiological understanding with broader discourses of governmentality, including the professional project of geriatric medicine. In particular, metaphorical representations in the discourses of frailty convey key cultural and clinical assumptions concerning both older bodies and old age more generally.

    The associate learning subtest from the Wechsler Memory Scale; Benton's Visual Retention test and a Controlled Word Association Task (FAS) were administered to a random sample of normal, healthy individuals whose age ranged from 20 to 79 years, recruited within the Italian peninsula. The neuropsychological examination took place on a mobile unit and the tests were given by the same team of neuropsychologists to reduce variability among examiners. The Research Project was known as Progetto Memoria. Corrections to the scores of these tests were calculated for age, sex, and education. These corrected values will allow clinicians to screen for memory impairment with greater precision among normally aging individuals, thus improving differential diagnosis between physiologic and pathologic deterioration of cognitive functions.

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

    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.

    We examined relationships between skinfold (SKF) and optical density (delta OD) measurements across age and levels of body fatness (%BF) for 151 women, 20 to 72 years. There were significant (p < .05) relationships between delta ODs and SKFs at all sites, except the thigh. The interaction (SKF x Age) was significant (p < .05) for pectoral and biceps delta ODs. Slope comparisons indicated the relationships for younger (29 years) and older (59 years) women differed significantly from zero and each other (p < .05). Analysis of SKF x %BF interactions revealed that relationships between SKFs and delta ODs at the pectoral and biceps sites for leaner (22% BF) women differed significantly from zero (p < .05) and were larger than those for obese (39% BF) women (p < or = .05). Thus, the relationship between SKFs and delta ODs is stronger for younger and leaner women compared to older and fatter women. These findings may reflect differences in fat layering due to age or body fatness and provide insight as to why the manufacturer's near-infrared (NIR) equation significantly underestimates the %BF of obese women.

    Sex estimation from the skull is commonly performed by physical and forensic anthropologists using a five-trait scoring system developed by Walker. Despite the popularity of this method, validation studies evaluating its accuracy across a variety of samples are lacking. Furthermore, it remains unclear what other intrinsic or extrinsic variables are related to the expression of these traits. In this study, cranial trait scores and postcranial measurements were collected from four diverse population groups (U.S. Whites, U.S. Blacks, medieval Nubians, and Arikara Native Americans) following Walker's protocols (total n = 499). Univariate and multivariate analyses were utilized to evaluate the accuracy of these traits in sex estimation, and to test for the effects of population, age, and body size on trait expressions. Results revealed significant effects of population on all trait scores. Sample-specific correct sex classification rates ranged from 74% to 94%, with an overall accuracy of 85% for the pooled sample. Classification performance varied among the traits (best for glabella and mastoid scores and worst for nuchal scores). Furthermore, correlations between traits were weak or nonsignificant, suggesting that different factors may influence individual traits. Some traits displayed correlations with age and/or postcranial size that were significant but weak, and within-population analyses did not reveal any consistent relationships between these traits across all groups. These results indicate that neither age nor body size plays a large role in trait expression, and thus does not need to be incorporated into sex estimation methods.

  2. Bodies, technologies, and aging in Japan: thinking about old people and their silver products.

    2012-06-01

    Contemporary Japan is known both for its high tech culture and its rapidly aging population, with 22 % of people currently 65 years and older. Yet there has been little attention to the material culture of the elderly. This paper explores the way aging bodies, official ideology, and consumption of what are called "assistive devices" and "life technologies" come together in the experience of frail old people who depend not only on human caregivers but on "things" such as walkers, kidney dialysis machines, and electric massage chairs. It begins to consider the questions: What technology to aid failing bodies is available, and to whom? How does the advocacy of independence create new forms of consumption? How do "things" mediate ideological change regarding elder care and help to create new understandings of self and one's relation to others? Data come from interviews conducted in 2003-2007 as part of a study of elder care in Japan under the public long term care insurance system that began in 2000. These interviews point both to acceptance of the technology as a way to avoid over-dependence on caregivers, and to resistance to the limitations of aging and to its 21st century definition by the state.

  3. Laryngeal apnea in rat pups: effects of age and body temperature.

    PubMed

    Xia, Luxi; Leiter, James C; Bartlett, Donald

    2008-01-01

    In neonatal mammals of many species, including human infants, apnea and other reflex responses frequently arise from stimulation of laryngeal receptors by ingested or regurgitated liquids. These reflexes, mediated by afferents in the superior laryngeal nerves (SLNs), are collectively known as the laryngeal chemoreflex (LCR) and are suspected to be responsible for some cases of the sudden infant death syndrome (SIDS). The LCR is strongly enhanced by mild increases in body temperature in decerebrate piglets, a finding that is of interest because SIDS victims are often found in overheated environments. Because of the experimental advantages of studying reflex development and mechanisms in neonatal rodents, we have developed methods for eliciting laryngeal apnea in anesthetized rat pups and have examined the influence of mild hyperthermia in animals ranging in age from 3 to 21 days. We found that apnea and respiratory disruption, elicited either by intralaryngeal water or by electrical stimulation of the SLN, occurred at all ages studied. Raising body temperature by 2-3 degrees C prolonged the respiratory disturbance in response to either stimulus. This effect of hyperthermia was prominent in the youngest animals and diminished with age. We conclude that many studies of the LCR restricted to larger neonatal animals in the past can be performed in infant rodents using appropriate methods. Moreover, the developmental changes in the LCR and in the thermal modulation of the LCR seem to follow different temporal profiles, implying that distinct neurophysiological processes may mediate the LCR and thermal prolongation of the LCR.

    Recent findings show that food craving represents an important co-factor in overweight and obesity etiology and its severity represents a good predictor of relapse during active weight control. Child overweight and obesity also represents significant predictive factor of adulthood obesity and evidence about its incidence in children is therefore important. In order to achieve this evidence the indices of food craving has measured in 150 older school age children (54 boys and 96 girls; mean age 13.6 ± 1.2). The food craving symptoms were measured by validated Czech translation of the General Food-Craving Questionnaire-Trait (G-FCQ-T). Body proportions of children were indexed by body-mass index (BMI). BMI were assessed according to cut-off points BMI references from the Czech Republic. Results have shown that older school children have experience with food craving symptoms, and that intensity of these symptoms is significantly associated with BMI value (r = 0.55; p < 0.0001). Statistical analysis also revealed higher incidence of food craving symptoms intensity in girls. These findings provide basic normative data about food craving symptoms occurrence and intensity in older school age children group. Presented results also indirectly support the hypothesis that food craving could represent important co-factor in childhood obesity etiology. The consequences for obesity psychotherapy will be discussed.

    I used captive young and adult American Black Ducks (Anas rubripes) during October-February 1984-1985 to test whether body weight and age affected time of pair-bond formation. Eighty ducks were marked individually, and 10 ducks (6 males and 4 females, half of each age class) were assigned to each of 8 experimental pens. Ducks in 4 pens received an ad libitum diet of commercial duck food, and ducks in the other 4 pens received a restricted ration of the same food. During early winter ducks in both groups gained weight, but ducks on the restricted diet gained less than birds on the ad libitum diet; peak winter weight of ducks on the ad libitum diet averaged 22% greater than initial body weight compared with 6.5% for ducks on the restricted diet. In late winter ducks on the restricted diet lost 28.7% of peak winter weight, and ducks on the ad libitum diet lost 19.3%. Weight loss of ducks on the ad libitum diet began before weather conditions became severe and coincided with a reduction in food consumption. This result supports the idea that weight loss of waterfowl in late winter is controlled endogenously. Individuals on the ad libitum diet paired earlier than those on the restricted diet, and pair bonds were stronger. Adults of both sexes paired earlier than young ducks, but differences for females were not significant statistically. Age and energy constraints are factors that can affect intraspecific variation in pairing chronology.

    Aging is associated with a fall in maximal aerobic capacity as well as with a decline in lean body mass. The purpose of the study was to investigate the influence of aging on the relationship between aerobic capacity and lean body mass in subjects that chronically train both their upper and lower bodies. Eleven older rowers (58±5 yrs) and 11 younger rowers (27±4 yrs) participated in the study. Prior to the VO2max testing, subjects underwent a dual energy X-ray absorptiometry scan to estimate total lean body mass. Subsequently, VO2max was quantified during a maximal exercise test on a rowing ergometer as well as a semi-recumbent cycle ergometer. The test protocol included a pre-exercise stage followed by incremental exercise until VO2max was reached. The order of exercise modes was randomized and there was a wash-out period between the two tests. Oxygen uptake was obtained via a breath-by-breath metabolic cart (Vmax™ Encore, San Diego, CA). Rowing VO2max was higher than cycling VO2max in both groups (p<0.05). Older subjects had less of an increase in VO2max from cycling to rowing (p<0.05). There was a significant relationship between muscle mass and VO2max for both groups (p<0.05). After correcting for muscle mass, the difference in cycling VO2max between groups disappeared (p>0.05), however, older subjects still demonstrated a lower rowing VO2max relative to younger subjects (p<0.05). Muscle mass is associated with the VO2max obtained, however, it appears that VO2max in older subjects may be less influenced by muscle mass than in younger subjects.

    Low vitamin D, commonly assessed as serum 25-hydroxyvitamin D (25OHD), is associated with the development of many age-related chronic diseases. A positive relationship exists between elevated 25OHD and muscle synthesis, strength, power, and decreased body fat in elderly individuals. However, these findings have not been consistently reported in younger healthy populations. The purpose of this study was to investigate the relationship between 25OHD and measures of body size, composition, metabolism, and physical fitness in a young physically active population. Thirty-nine subjects (20 men, 19 women; aged 23 ± 0.7 years) reported 6 times for testing. Blood was collected to determine 25OHD. Primary outcomes included the following: body mass index (BMI) and percent body fat (dual x-ray absorptiometry); resting metabolic rate; maximal oxygen uptake (V[Combining Dot Above]O2max); power output (Wingate); and muscular strength (8 repetition maximum for bench press, upright row, and leg extension and flexion exercises). Our analysis included all participants, and subgroup analyses for individuals with suboptimal 25OHD concentration below 35 ng·mL ("low"; n = 20, 25.97 ± 1.97 ng·mL) or equal to and above 35 ng·mL ("high"; n = 19, 44.15 ± 2.17 ng·mL). Twenty subjects in this study had serum levels of 25OHD below 35 ng·mL. There was a significant positive relationship between V[Combining Dot Above]O2max and serum 25OHD and a negative relationship between BMI and serum 25OHD. These data suggest that vitamin D deficiency is prevalent even in a young physically active population in the southern United States and that there was a positive relationship between a measure of cardiovascular fitness and serum 25OHD, and a negative relationship between serum 25OHD and BMI.

    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

    The goal of this study was to test the relative effectiveness of morphological measurements and body size in predicting the smolt age of Atlantic salmon Salmo salar and to determine the time course of body size and shape differences between smolt ages. Analyses were conducted on age-0 to age-2 fish that were stocked as fry in the West Brook, Massachusetts and on laboratory-raised age-0 to age-1 fish. Using both body size and shape, we could partition the age-0 fish collected during fall into future early or late smolts, although the predictive ability of body shape was somewhat weaker than that of body size, especially in the laboratory. Classification success averaged 81% (size) and 79% (shape) in the field and 85% (size) and 73% (shape) in the laboratory. Despite differences in smolt age between the field and the laboratory, the relative timing of growth rate differences between future early and late smolts was similar in the field and the laboratory and peaked at 50-60% of development from fry to smolt. While body shape differed between early and late smolts well before smoltification, it did not improve classification based on size alone.

    2003-09-01

    A number of studies have shown that dieting and body dissatisfaction are highly frequent among adolescents. We here describe the relationship between dieting and body dissatisfaction in 4,952 children selected from the 11, 13 and 15 year age cohorts of the Norwegian national sample in the multinational WHO survey "Health Behavior in School Children". Body dissatisfaction was defined as the subjective experience of being a bit or much too fat and, using this definition, about 20% of the boys reported body dissatisfaction and 7% that they were on a diet. About 37% of the girls reported body dissatisfaction and 15% that they were on a diet. Within the age cohorts, respectively 22%, 30% and 32% reported body dissatisfaction, whereas about 40% overall indicated no body dissatisfaction. Being on a diet was reported by 8% of the 11-year olds, and subsequently increased to 10% (13 years) and 14% (15 years). Multiple regression analysis showed that body dissatisfaction explained 33% of the variance in dieting behaviour, and that the overall effect of gender and age was small. Dieting and body dissatisfaction should therefore be recognised as being equally important among boys, and be counteracted within the framework of a health promotion strategy aimed at the general adolescent population.

    Data on age and body weight at breeding, parity, previous litter size, days open and some descriptive body linear traits from 389 meat-type, prolific Black Bengal goats in Tripura State of India, were collected for 3 and 1/2 years (2007 to 2010) and analyzed using logistic regression model. The objectives of the study were i) to evaluate the effect of age and body weight at breeding, parity, previous litter size and days open on litter size of does; and ii) to investigate if body linear type traits influenced litter size in meat-type, prolific goats. The incidence of 68.39% multiple births with a prolificacy rate of 175.07% was recorded. Higher age (>2.69 year), higher parity order (>2.31), more body weight at breeding (>20.5 kg) and larger previous litter size (>1.65) showed an increase likelihood of multiple litter size when compared to single litter size. There was a strong, positive relationship between litter size and various body linear type traits like neck length (>22.78 cm), body length (>54.86 cm), withers height (>48.85 cm), croup height (>50.67 cm), distance between tuber coxae bones (>11.38 cm) and distance between tuber ischii bones (>4.56 cm) for discriminating the goats bearing multiple fetuses from those bearing a single fetus.

    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

    The authors have measured total body water (TBW, by dessiccation), extracellular fluid volume (ECF, Na{sub 2}{sup 35}SO{sub 4} space), and plasma volume (PV, radioiodinated serum albumin space) in 5-sec-butyl-5-ethyl-2-thiobarbituric acid and sodium salt (Inactin)-anesthetized spontaneously hypertensive (SHR) and Wistar-Kyoto (WKY) rats aged 12-60 days. Interstitial fluid volume (ISF) was calculated as ECF minus PV. Changes in TBW, ECF, and ISF were largely a function of age in both strains, which is typical of developing mammals. Further analysis revealed that although these volumes were significantly larger in SHR before 25 days of age, after 30 days no difference existed between the strains. Before 25 days of age, when SHR's TBW was expanded, no weight difference was seen between the strains. However, once TBW was normalized (after 30 days), WKY was significantly heavier than SHR. The ISF volume was preferentially enlarged in SHR, although PV was also periodically greater. ISF normalized at the time when blood pressure becomes significantly higher in SHR, when plasma aldosterone falls to WKY values in SHR and when renal function is approaching adult levels. Thus the return of ECF (ISF) to normal values may be a result of decreased aldosterone-dependent volume retention or to diuresis induced by increasing blood pressure in an animal whose renal function is close to maturity.

    The article presents an current knowledge overview about the importance of oxidative stress and reduced efficiency of repair processes during the aging process of the human body. Oxidative damage to cellular macromolecules (proteins, lipids, nucleic acids), are formed under the influence of reactive oxygen species (ROS). They are the part of important mechanism which is responsible for the process of aging and the development of many diseases. The most important effects result from DNA damage, due to the mutations formation, which can lead to the development of tumors. However, a well-functioning repair systems (i.a. homologous recombination) remove the damage and prevent harmful changes in the cells. Lipid peroxidation products also cause oxidative modification of nucleic acids (and proteins). Proteins and fats also have repair systems, but much simpler than those responsible for the repair of nucleic acids. Unfortunately, with increasing age, they are more weakened, which contributes to increase numbers of cell damage, and consequently development of diseases specific to old age: cancer, neurodegenerative diseases or atherosclerosis.

    Context: Numerous factors are purported to influence insulin sensitivity including age, adiposity, mitochondrial function, and physical fitness. Univariate associations cannot address the complexity of insulin resistance or the interrelationship among potential determinants. Objective: The objective of the study was to identify significant independent predictors of insulin sensitivity across a range of age and adiposity in humans. Design, Setting, and Participants: Peripheral and hepatic insulin sensitivity were measured by two stage hyperinsulinemic-euglycemic clamps in 116 men and women (aged 19–78 y). Insulin-stimulated glucose disposal, the suppression of endogenous glucose production during hyperinsulinemia, and homeostatic model assessment of insulin resistance were tested for associations with 11 potential predictors. Abdominal subcutaneous fat, visceral fat (AFVISC), intrahepatic lipid, and intramyocellular lipid (IMCL) were quantified by magnetic resonance imaging and spectroscopy. Skeletal muscle mitochondrial respiratory capacity (state 3), coupling efficiency, and reactive oxygen species production were evaluated from muscle biopsies. Aerobic fitness was measured from whole-body maximum oxygen uptake (VO2 peak), and metabolic flexibility was determined using indirect calorimetry. Results: Multiple regression analysis revealed that AFVISC (P < .0001) and intrahepatic lipid (P = .002) were independent negative predictors of peripheral insulin sensitivity, whereas VO2 peak (P = .0007) and IMCL (P = .023) were positive predictors. Mitochondrial capacity and efficiency were not independent determinants of peripheral insulin sensitivity. The suppression of endogenous glucose production during hyperinsulinemia model of hepatic insulin sensitivity revealed percentage fat (P < .0001) and AFVISC (P = .001) as significant negative predictors. Modeling homeostatic model assessment of insulin resistance identified AFVISC (P < .0001), VO2 peak (P = .001), and IMCL

    Physical activity (PA) is beneficial to overall health, in part due to physiological changes that lower risk factors for cardiovascular disease, including reduced inflammation. However, the mechanism by which PA reduces inflammation is unclear. One possible pathway is that PA improves body composition which in turn reduces inflammation. To test this hypothesis, we used structural equation modeling (SEM) to assess PA-body composition -inflammation pathways, as well as influences of age. In a sample of 72 healthy males with a range of PA profiles (age 18-65, mean ± sd = ), we measured PA as metabolic equivalent tasks (as per the International PA Questionnaire), body composition as percent body fat, lean mass, and fat mass, and inflammation as plasma interleukin-6 (IL-6). We treated body composition in the SEM analysis as a latent variable indicated by the three measures. We performed statistical corrections for missing values and one outlier. The model demonstrated significant effects of PA on IL-6 both directly and through body composition. Percent body fat, fat mass, and lean mass were significant indicators of the body composition latent variable. Additionally, age showed an indirect effect on IL-6 through body composition, but no direct effect. The findings suggest that PA does improve inflammatory profile through improving body composition, but that other pathways also exist.

  2. Effect of temperature, ration, body size and age on sulphur isotope fractionation in fish.

    Sulphur isotope analysis (delta(34)S) is increasingly identified as a valuable tool for source differentiation and the determination of trophic level in food webs, but there are still many uncertainties associated with the interpretation of delta(34)S data. To investigate the effects of temperature, ration, body size and age on sulphur trophic fractionation (Deltadelta(34)S) in fish, we reared European sea bass (Dicentrarchus labrax) on identical diets at 11 and 16 degrees C at three ration levels for over 600 days. Deltadelta(34)S was between 0 and -1 per thousand. The effect of temperature on Deltadelta(34)S was small and inconsistent, varying over the course of the experiment and depending on ration. This contrasts with temperature effects on bass Deltadelta(13)C and Deltadelta(15)N, where Deltadelta(13)C increases at warm temperatures while Deltadelta(15)N falls. Body size and age had a positive relationship with Deltadelta(34)S but the relationship with size was not significant for bass that weighed >20 g. As Deltadelta(34)S is small and the range in delta(34)S of potential diet items can be much greater than the range in delta(13)C or delta(15)N, our results show that sulphur stable isotopes are particularly useful for source differentiation in fish.

    In birds, larger females generally have greater breeding propensity, reproductive investment, and success than do smaller females. However, optimal female body size also depends on how natural selection acts during other parts of the life cycle. Larger female Lesser Scaup (Aythya affinis) produce larger eggs than do smaller females, and ducklings from larger eggs survive better than those hatching from smaller eggs. Accordingly, we examined patterns of apparent annual survival for female scaup and tested whether natural selection on female body size primarily was stabilizing, a frequent assumption in studies of sexually dimorphic species in which males are the larger sex, or was directional, counter-acting reproductive advantages of large size. We estimated survival using mark-recapture methods for individually marked females from two study sites in Canada (Erickson, Manitoba; St. Denis, Saskatchewan). Structurally larger (adults) and heavier (ducklings) females had lower survival than did smaller individuals in Manitoba; no relationship was detected in adults from Saskatchewan. Survival of adult females declined with indices of increasing reproductive effort at both sites; consequently, the cost of reproduction could explain age-related patterns of breeding propensity in scaup. Furthermore, if larger females are more likely to breed than are smaller females, then cost of reproduction also may help explain why survival was lower for larger females. Overall, we found that advantages of large body size of female scaup during breeding or as young ducklings apparently were counteracted by natural selection favoring lightweight juveniles and structurally smaller adult females through higher annual survival.

    Objective To determine the relation between body mass index (BMI) and liver cirrhosis and the contribution that BMI and alcohol consumption make to the incidence of liver cirrhosis in middle aged women in the UK. Design Prospective cohort study (Million Women Study). Setting Women recruited from 1996 to 2001 in NHS breast screening centres and followed by record linkage to routinely collected information on hospital admissions and deaths. Participants 1 230 662 women (mean age 56 years at recruitment) followed for an average of 6.2 years. Main outcome measures Relative risk and absolute risk of first hospital admission with or death from liver cirrhosis adjusted for age, recruitment region, alcohol consumption, smoking, socioeconomic status, and physical activity. Results 1811 women had a first hospital admission with or died from liver cirrhosis during follow-up. Among women with a BMI of 22.5 or above, increasing BMI was associated with an increased incidence of liver cirrhosis: the adjusted relative risk of cirrhosis increased by 28% (relative risk 1.28, 95% confidence interval 1.19 to 1.38; P<0.001) for every 5 unit increase in BMI. Although the relative increase in the risk of liver cirrhosis per 5 unit increase in BMI did not differ significantly according to the amount of alcohol consumed, the absolute risk did. Among women who reported drinking less than 70 g alcohol per week, the absolute risk of liver cirrhosis per 1000 women over five years was 0.8 (0.7 to 0.9) for those with a BMI between 22.5 and 25 and 1.0 (0.9 to 1.2) for those with a BMI of 30 or more. Among women who reported drinking 150 g alcohol or more per week, the corresponding figures were 2.7 (2.1 to 3.4) and 5.0 (3.8 to 6.6). Conclusions Excess body weight increases the incidence of liver cirrhosis. In middle aged women in the UK, an estimated 17% of incident or fatal liver cirrhosis is attributable to excess body weight. This compares with an estimated 42% attributable to alcohol

    We studied the effect of genetic and environmental factors on the association between self-reported height and education in Minnesota and Finland. Our data included 1,598 twin pairs in Minnesota and 5,454 twin pairs in Finland born between 1936 and 1955. Correlations between education and height were found in Minnesota (r = 0.09 in men and 0.11 in women) and in Finland (r = 0.17 and 0.14, respectively) after adjustment for age. This trait correlation was mainly because of the correlation between shared environmental factors in Minnesota (r(C) = 0.38 and 0.36, respectively) and in Finland (r(C) = 0.74 and 0.37, respectively). An unshared environmental correlation was found only in Finland (r(E) = 0.13 and 0.06, respectively). Our results indicate that the association between body height and education is overwhelmingly due to the correlation of the shared environmental factors affecting these two traits. The differences between Minnesota and Finland are possibly associated with average higher education in Minnesota, which decreases the effect of the childhood environment on education, seen as a weaker correlation between height and education. Nonfamilial factors affecting education are possibly different in Minnesota than in Finland, since in Finland they are partly associated with the factors affecting height.

    The present study was conducted to examine whether prepubertal-onset exercise might help adults maintain long-term body weight (BW) reduction and increased energy metabolism after the cessation of exercise. Furthermore, the effects of the exercise regimen were compared with those of food restriction. Twenty-three male obese-diabetic [Otsuka Long-Evans Tokushima Fatty (OLETF)] rats were randomly assigned to prepubertal-onset exercise (Childhood-Ex), food restriction (Childhood-Diet), and sedentary control (OLETF-Sed) groups. Childhood-Ex rats exercised voluntarily every day using a rotating wheel, while the food volume of the Childhood-Diet group was restricted to achieve a BW similar to that recorded in the Childhood-Ex group. Both treatments were conducted at 5-19 wk of age; after this period, the rats were kept sedentary and allowed ad libitum food intake until 45 wk of age. BW was significantly lower, and percent lean body mass was significantly higher, in the Childhood-Ex group compared with those in the Childhood-Diet and OLETF-Sed groups throughout maturation and middle age after cessation of the interventions. The Childhood-Ex group also demonstrated higher citrate synthase, succinate dehydrogenase, and phosphofructokinase activity levels, as well as uncoupling protein-3 mRNA expression in skeletal muscle. This study revealed that inhibited BW gain in an animal model of human obese diabetes by prepubertal-onset exercise lasted for a long period after the completion of the exercise intervention. This effect may be facilitated by increased energy metabolism. However, these benefits were not found by prepubertal food restriction treatment. Importantly, to allow translation of our work, these novel insights need to be assessed in obese human individuals.

    Anthropometric reference data for older adults, particularly for the oldest old, are still limited, especially in developing countries. The aim of the present study was to describe sex- and age-specific distributions of anthropometric measurements and body composition in Mexican older adults. The methods included in the present study were assessment of height, weight, BMI, calf circumference (CC), waist circumference (WC) and hip circumference (HC) as well as knee height in a sample of 8883 Mexican adults aged 60 years and above and the estimation of sex- and age-specific differences in these measures. Results of the study (n 7865, 54% women) showed that men are taller, have higher BMI, and larger WC than women, whereas women presented higher prevalence of obesity and adiposity. Overall prevalence of underweight was 2·3% in men and 4·0% in women, with increasing prevalence with advancing age. Significant differences were found by age group for weight, height, WC, HC, CC, BMI and knee height (P<0·001), but no significant differences in waist-hip circumference were observed. Significant differences between men and women were found in height, weight, circumferences, BMI and knee height (P<0·001). These results, which are consistent with studies of older adults in other countries, can be used for comparison with other Mexican samples including populations living in the USA and other countries with similar developmental and socio-economic conditions. This information can also be used as reference in clinical settings as a tool for detection of individuals at risk of either underweight or overweight and obesity.

    Carpal tunnel syndrome (CTS) has a multifactorial etiology involving systemic, anatomical, idiopathic, and ergonomic characteristics. In this study, an investigation of the relationship between the CTS degree established by electrophysiological measurements in patients with clinical CTS prediagnosis, and age, gender, body mass index (BMI), hand wrist circumference, and waist circumference measurements has been done. On 547 patients included in the study, motor and sensory conduction examinations of the median and ulnar nerve were done on one or two upper extremities thought to have CTS. In terms of CTS severity, the patients were divided into four groups (normal, mild, medium, and severe CTS). A total of 843 electrophysiological examinations were done consisting of 424 on the right hand wrist and 419 on the left hand wrist. When the age group of 18-35 years is taken as the reference group, the CTS development risk independent of BMI has been found to have increased by a factor of 1.86 for ages 36-64 years, and by 4.17 for ages 65 years and higher after adjustment for BMI. With respect to normal degree CTS group, the BMI were significantly different in groups with mild, medium, and severe CTS. The waist circumferences of groups with mild, medium, and severe CTS severity were found to be significantly higher in comparison to the normal reference group. When this value was corrected with BMI and re-examined the statistically significant differences persisted. The study identified a significant relationship between the CTS severity and age, BMI, waist circumference.

    The obesity epidemic is a significant public health issue with adverse impact on health and costs. Applying a life-course perspective to obesity may advance our understanding of the influence of obesity over time on patterns of healthcare utilization in young and middle-aged United States (US) adults.We identified baseline body mass index (BMI) and BMI trajectories, and assessed their association with outpatient visits, emergency department (ED) visits, and hospitalizations in a well-defined population of young and middle-aged US adults.Using the Rochester Epidemiology Project resources, we conducted a retrospective cohort study of adults (N = 23,254) aged 18 to 44 years, with at least 3 BMI measurements, residing in Olmsted County, MN from January 1, 2005 through December 31, 2012.We observed that 27.5% of the population was obese. Four BMI trajectories were identified. Compared to under/normal weight, obese class III adults had higher risk of outpatient visits (adjusted rate ratio [RR], 1.86; 95% confidence intervals [CIs], 1.67-2,08), ED visits (adjusted RR, 3.02; 95% CI, 2.74-3.34), and hospitalizations (adjusted RR, 1.67; 95% CI, 1.59-1.75). BMI trajectory was positively associated with ED visits after adjustment for age, sex, race, and Charlson Comorbidity Index (P < 0.001 for trend).Among young and middle-aged US adults, baseline BMI is positively associated with outpatient visits, ED visits, and hospitalizations, while BMI trajectory is positively associated with ED visits. These findings extend our understanding of the longitudinal influence of obesity on healthcare utilization in early to mid-adulthood.

  20. Aging

    PubMed Central

    Park, Dong Choon

    2013-01-01

    Aging is initiated based on genetic and environmental factors that operate from the time of birth of organisms. Aging induces physiological phenomena such as reduction of cell counts, deterioration of tissue proteins, tissue atrophy, a decrease of the metabolic rate, reduction of body fluids, and calcium metabolism abnormalities, with final progression onto pathological aging. Despite the efforts from many researchers, the progression and the mechanisms of aging are not clearly understood yet. Therefore, the authors would like to introduce several theories which have gained attentions among the published theories up to date; genetic program theory, wear-and-tear theory, telomere theory, endocrine theory, DNA damage hypothesis, error catastrophe theory, the rate of living theory, mitochondrial theory, and free radical theory. Although there have been many studies that have tried to prevent aging and prolong life, here we introduce a couple of theories which have been proven more or less; food, exercise, and diet restriction.

    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.

    The degree of assortative mating for psychological and physical traits in Asian societies in relatively unknown. The present study examined assortative mating for educational level, personality traits, religious affiliation, height, weight, and body mass index in a korean sample. Age-adjusted spouse correlations were high for educational level (r = .63) and religious affiliation (r = .67), modest for most personality traits (rs = -.01 to .26), and trivial for height (r = .04), weight (r = .05)m and body mass index (r = .11). These results were remarkably similar to those found from the western samples. Implications of the present findings in behavior genetic studies and human mating patterns were briefly discussed.

    ABSTRACT Objectives: To study the impact of obesity, age and varicocele on sexual hormones fof adult and elderly men. Materials and Methods: 875 men who were screened for prostate cancer were enrolled in this study. Data recorded comprised age, body mass index (BMI), serum levels of total testosterone (TT), free testosterone (FT), sex hormone-binding globulin (SHBG), luteinizing hormone (LH) and follicular stimulating hormone (FSH). Patients were divided in groups according to their BMI in underweight, normal weight, overweight and obese grades 1, 2 or 3. First, it was studied the association between age, BMI, and hormone profile. Then, clinical varicocele was evaluated in 298 patients to assess its correlation to the others parameters. Results: Obese patients had lower levels of TT, FT and SHBG (p<0.001) compared to underweight or normal weight patients. There were no differences in age (p=0.113), FSH serum levels (p=0.863) and LH serum levels (p=0.218) between obese and non-obese patients. Obese grade 3 had lower levels of TT and FT compared to obese grade 1 and 2 (p<0.05). There was no difference in the SHBG levels (p=0.120) among obese patients. There was no association between varicocele and BMI; and varicocele did not impact on testosterone or SHBG levels. Conclusions: Men with higher BMI have a lower serum level of TT, FT and SHBG. The presence of clinical varicocele as well as its grade has no impact on hormone profile in elderly men. PMID:27256193

    Female hypocretin knockout (Hcrt KO) mice have increased body weight despite decreased food intake compared to wild type (WT) mice. In order to understand the nature of the increased body weight, we carried out a detailed study of Hcrt KO and WT, male, and female mice. Female KO mice showed consistently higher body weight than WT mice, from 4 to 20 months (20-60%). Fat, muscle, and free fluid levels were all significantly higher in adult (7-9 months) as well as old (18-20 months) female KO mice compared to age-matched WT mice. Old male KO mice showed significantly higher fat content (150%) compared to age-matched WT mice, but no significant change in body weight. Respiratory quotient (-19%) and metabolic rates (-14%) were significantly lower in KO mice compared to WT mice, regardless of gender or age. Female KO mice had significantly higher serum leptin levels (191%) than WT mice at 18-20 months, but no difference between male mice were observed. Conversely, insulin resistance was significantly higher in both male (73%) and female (93%) KO mice compared to age- and sex-matched WT mice. We conclude that absence of the Hcrt peptide has gender-specific effects. In contrast, Hcrt-ataxin mice and human narcoleptics, with loss of the whole Hcrt cell, show weight gain in both sexes.

  12. On the age and parent body of the daytime Arietids meteor shower

    2016-01-01

    The daytime Arietid meteor shower is active from mid-May to late June and is among the strongest of the annual meteor showers, comparable in activity and duration to the Perseids and the Geminids. Due to the daytime nature of the shower, the Arietids have mostly been constrained by radar studies. The Arietids exhibit a long-debated discrepancy in the semi-major axis and the eccentricity of meteoroid orbits as measured by radar and optical surveys. Radar studies yield systematically lower values for the semi-major axis and eccentricity, where the origin of these discrepancies remain unclear. The proposed parent bodies of the stream include comet 96P/Machholz and more recently the Marsden's group of sun-skirting comets. In this work, we present detailed numerical modelling of the daytime Arietid meteoroid stream, with the goal to identifying the parent body and constraining the age of the stream. We use observational data from an extensive survey of the Arietids by the Canadian Meteor Orbit Radar (CMOR), in the period of 2002-2013, and several optical observations by the SonotaCo meteor network and the Cameras for All-sky Meteor Surveillance (CAMS). Our simulations suggest that the age and observed characteristics of the daytime Arietids are consistent with cometary activity from 96P, over the past 12000 years. The sunskirting comets that presumably formed in a major comet breakup between 100 - 950 AD (Chodas and Sekanina, 2005), alone, cannot explain the observed shower characteristics of the Arietids. Thus, the Marsden sunskirters cannot be the dominant parent, though our simulations suggest that they contribute to the core of the stream.

    Agriculture is one of the nation's more hazardous occupations, and injury prevention among agricultural workers is a focus of safety and education programs nationwide. This research project investigated the effectiveness of a culturally appropriate body mechanics education program for fruit warehouse workers in Washington State. The purpose of the body mechanics education program was to promote correct ergonomic behavior among migrant and seasonal fruit warehouse workers. Participants received instruction in proper body mechanics by viewing a videotaped Spanish-language theatre program (with English subtitles) followed by a demonstration and practice of correct lifting techniques and selected stretches for injury prevention. A written pre- and post-test to assess body mechanics knowledge and an evaluation of lifting methods were administered at the time of the training and again two weeks later. The results indicated culturally appropriate body mechanics education is an effective intervention for increasing knowledge and promoting correct lifting techniques. However, further research is indicated to examine the significance of supervised and individualized, job-specific practice on affecting more lasting changes in work-related body mechanics and lifting behaviors.

    2014-12-01

    Mathematical modelling of the relationships between mineral inputs and outputs would enable the prediction of mineral requirements of poultry under a wide range of conditions. To establish the feasibility of possible modelling of mineral requirements, the current study aimed to describe the individual mineral concentrations of whole bodies of quail over the life cycle from hatching to 70 days of age. Quail were reared indoors without any restrictions that could limit growth. Sampling of birds (n = 6-18) was carried out at 0, 3, 7, 14, 21, 35, 49 and 70 days after hatching. Freeze-dried samples of whole bodies (digestive contents removed) were analysed for ash, and macrominerals (calcium, magnesium, phosphorus, potassium, sodium) and microminerals (copper, iron, manganese, nickel, selenium, zinc). Ash concentration followed a curvilinear trend, with a maximum of 101.7 g/kg dry matter at 32.77 days. Individual mineral concentrations, expressed as a proportion of ash, were fluctuating over time, with the most prominent changes at 3 days and again at either 14 or 21 days. Dissimilar patterns in individual mineral concentrations resulted that ratios between minerals followed inconsistent patterns over time. Although mineral contents in absolute quantities can be described through modelling over the entire life cycle of the bird, it can be concluded that variable concentrations of individual minerals could complicate further model development.

    Obesity prevalence and average body composition vary by US race and gender. Asian Americans have the lowest prevalence of obesity. Relying on body-mass index (BMI) to estimate obesity prevalence may misclassify subgroups that appear normally weighted but have excess body fat. We evaluated percentage body fat (PBF) and BMI to determine whether BMI reflects PBF consistently across different races. 940 college students were recruited from a local public university over four consecutive years. We measured PBF by bioelectrical impedance analysis (BIA), weight by physicians' scales, and height with stadiometers. Our sample comprised Asians (49%), Caucasians (23%), Hispanics (7%), and Other (21%). Participants averaged 21.4 years old; BMI was 22.9 kg/m2; PBF was 24.8%. BMI and PBF varied significantly by race and gender (P value = 0.002 and 0.005 for men; 0.0009 and 0.0008 for women). Asian-American women had the lowest BMI (21.5 kg/m2) but the second highest PBF (27.8%). Linear association between BMI and PBF was the weakest (r2 = 0.09) among Asian-American women and BMI had the poorest sensitivity (37%) to detect PBF. The high PBF with low BMI pattern exhibited by Asian-American women suggests that they could escape detection for obesity-related disease if BMI is the sole measure that estimates body composition.

    Technological advancements in past decades have led to the development of integrative analytical approaches to lipidomics, such as liquid chromatography-mass spectrometry (LC/MS), and information about biogenic lipids is rapidly accumulating. Although several cohort-based studies have been conducted on the composition of urinary lipidome, the data on urinary lipids cross-classified by sex, age, and body mass index (BMI) are insufficient to screen for various abnormalities. To promote the development of urinary lipid metabolome-based diagnostic assay, we analyzed 60 urine samples from healthy white adults (young (c.a., 30 years) and old (c.a., 60 years) men/women) using LC/MS. Women had a higher urinary concentration of omega-3 12-lipoxygenase (LOX)-generated oxylipins with anti-inflammatory activity compared to men. In addition, young women showed increased abundance of poly-unsaturated fatty acids (PUFAs) and cytochrome P450 (P450)-produced oxylipins with anti-hypertensive activity compared with young men, whereas elderly women exhibited higher concentration of 5-LOX-generated anti-inflammatory oxylipins than elderly men. There were no significant differences in urinary oxylipin levels between young and old subjects or between subjects with low and high BMI. Our findings suggest that sex, but neither ages nor BMI could be a confounding factor for measuring the composition of urinary lipid metabolites in the healthy population. The information showed contribute to the development of reliable biomarker findings from urine. PMID:27973561

    The proposition that increased energy expenditure shortens life has a long history. The rate-of-living theory (Pearl 1928 ) states that life span and average mass-specific metabolic rate are inversely proportional. Originally based on interspecific allometric comparisons between species of mammals, the theory was later rejected on the basis of comparisons between taxa (e.g., birds have higher metabolic rates than mammals of the same size and yet live longer). It has rarely been experimentally tested within species. Here, we investigated the effects of increased energy expenditure, induced by cold exposure, on longevity in mice. Longevity was measured in groups of 60 male mice maintained at either 22 degrees C (WW) or 10 degrees C (CC) throughout adult life. Forty additional mice were maintained at both of these temperatures to determine metabolic rate (by stable isotope turnover, gas exchange, and food intake) as well as the mass of body and organs of subsets of animals at four different ages. Because energy expenditure might affect longevity by either accumulating damage or by instantaneously affecting mortality rate, we included a third group of mice exposed to 10 degrees C early in life and to 22 degrees C afterward (CW). Exposure to cold increased mean daily energy expenditure by ca. 48% (from 47.8 kJ d(-1) in WW to 70.6 kJ d(-1) in CC mice, with CW intermediate at 59.9 kJ d(-1)). However, we observed no significant differences in median life span among the groups (WW, 832 d; CC, 834 d; CW, 751 d). CC mice had reduced body mass (lifetime mean 30.7 g) compared with WW mice (33.8 g), and hence their lifetime energy potential (LEP) per gram whole-body mass had an even larger excess than per individual. Greenberg ( 1999 ) has pointed out that the size of the energetically costly organs, rather than that of the whole body, may be relevant for the rate-of-living idea. We therefore expressed LEP also in terms of energy expenditure per gram dry lean mass or per gram

    Recent studies suggest that whole-body vibration (WBV) can improve measures of bone health for certain clinical conditions and ages. In the elderly, there also is particular interest in assessing the ability of physical interventions such as WBV to improve coordination, strength, and movement speed, which help prevent falls and fractures and maintain ambulation for independent living. The current study evaluated the efficacy of WBV in an aging mouse model. Two levels of vibration--0.5 and 1.5g--were applied at 32Hz to CB57BL/6 male mice (n=9 each) beginning at age 18 months and continuing for 12 weeks, 30 min/day, in a novel pivoting vibration device. Previous reports indicate that bone parameters in these mice begin to decrease substantially at 18 months, equivalent to mid-fifties for humans. Micro-computed tomography (micro-CT) and biomechanical assessments were made in the femur, radius, and lumbar vertebra to determine the effect of these WBV magnitudes and durations in the aging model. Sera also were collected for analysis of bone formation and breakdown markers. Mineralizing surface and cell counts were determined histologically. Bone volume in four regions of the femur did not change significantly, but there was a consistent shift toward higher mean density in the bone density spectrum (BDS), with the two vibration levels producing similar results. This new parameter represents an integral of the conventional density histogram. The amount of high density bone statistically improved in the head, neck, and diaphysis. Biomechanically, there was a trend toward greater stiffness in the 1.5 g group (p=0.139 vs. controls in the radius), and no change in strength. In the lumbar spine, no differences were seen due to vibration. Both vibration groups significantly reduced pyridinoline crosslinks, a collagen breakdown marker. They also significantly increased dynamic mineralization, MS/BS. Furthermore, osteoclasts were most numerous in the 1.5 g group (p≤ 0

    Conjugated linoleic acids (CLA) have been shown to have remarkable yet inconsistent metabolic effects in mice, rats, hamsters, chickens, cattle, and humans. In particular, effects on lipogenesis vary with tissue, physiological state, and species. In this study we tested the hypothesis that CLA would differentially affect ducks of the same genetic background but of differing age. Growing (7 wk) and maintenance (11 wk) Moulard ducks were grouped by age and fed a standard diet supplemented with 5% soybean oil (control) or 5% CLA isomer mixture. Birds were slaughtered after 3 or 6 wk for assessment of body composition including adipose, liver, viscera, and empty carcass weight. Serum nonesterified fatty acid (NEFA) and glucose concentrations were evaluated, and gene targets were cloned from the duck to use in quantifying mRNA abundance for genes involved in lipogenesis (fatty acid synthase, FAS; acetyl-CoA carboxylase, ACC) and lipid oxidation (carnitine palmitoyl transferase-1, CPT-1) in liver tissue from maintenance birds. After 3 wk, the growing CLA group exhibited a 24% decrease in dissectible adipose tissue (P < 0.05), whereas maintenance birds showed no significant diet effect. After 6 wk, the growing CLA group exhibited a 20% increase in liver mass compared with the control (P < 0.05), but no diet effect on adipose tissue. Maintenance birds receiving dietary CLA had a 42% decrease in adipose tissue mass after 6 wk; increased serum NEFA, ACC, and CPT-1 mRNA after 3 and 6 wk (P < 0.05); and increased FAS mRNA after 3 wk of treatment (P < 0.05). These data indicate that CLA have potent effects on lipid metabolism in ducks, but these effects differ depending on physiological age.

    Objective To describe and explore perceptions, practices and motivations for active living in later life. Design Qualitative study with semistructured interviews and ‘semistructured’ participant observations of participant-selected activities, such as exercise classes, private or organised walks, shopping and gardening. Participants 27 participants (65–80 years) from the European Prospective Investigation into Cancer Norfolk study, purposefully selected by gender, age, occupational class, living status and residential location; 19 of the participants agreed to be accompanied for observed activities. Setting Participants’ homes, neighbourhoods, places of leisure activities and workplaces in Norfolk, England. Results All participants regarded a positive attitude as important for healthy ageing; this included staying active, both physically and mentally through sedentary activities such as reading and crosswords. ‘Getting out of the house’, being busy, or following a variety of interests were regarded as both important motivators and descriptions of their ‘activeness’. Purposeful activities formed an important part of this, for example, still being engaged in paid or voluntary work, having caring responsibilities, or smaller incidental activities such as helping neighbours or walking for transport. Many also reported adapting previous, often lifelong, activity preferences and habits to their ageing body, or replacing them altogether with lower impact activities such as walking. This included adapting to the physical limitations of partners and friends which dictated the intensity and frequency of shared activities. The social context of activities could thus form a barrier to active living, but could also encourage it through companionship, social responsibilities and social pressures. Conclusions Promoting and maintaining physical activity among older people may require more attention to activeness as an attitude and way of life as well as to its

    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.

    The objective of the present study was to determine the number of ovulations in culled Landrace × Yorkshire (LY) crossbred gilts in the tropics associated with age, body weight and growth rate. The genital organs from 316 gilts were examined for gross abnormalities, and those with normal cyclic ovaries (n=155, 307 ± 4.1 days of age, 148 ± 1.6 kg body weight) were included in the analyses. Number of ovulations was defined by a count of the corpora lutea (CL) from both ovaries. On average, the number of ovulations in LY gilts was 15.9 ± 0.3 (range 4 to 27). The number of ovulations correlated with the body weight (r=0.31, P<0.001) and growth rate (r=0.20, P=0.015) of the gilts, but not with their age (P>0.05). Gilts with a body weight of 141 to 150 kg (17.0 CL, n=31) ovulated more than those with a body weight ≤130 kg (14.1 CL, P=0.014, n=23). In conclusion, both the body weight and growth rate of the gilts were significantly correlated with the number of ovulations. The maximum number of ovulations was found in gilts at a body weight of above 141 kg.

  3. Calorie restriction lowers body temperature in rhesus monkeys, consistent with a postulated anti-aging mechanism in rodents.

    Many studies of caloric restriction (CR) in rodents and lower animals indicate that this nutritional manipulation retards aging processes, as evidenced by increased longevity, reduced pathology, and maintenance of physiological function in a more youthful state. The anti-aging effects of CR are believed to relate, at least in part, to changes in energy metabolism. We are attempting to determine whether similar effects occur in response to CR in nonhuman primates. Core (rectal) body temperature decreased progressively with age from 2 to 30 years in rhesus monkeys fed ad lib (controls) and is reduced by approximately 0.5 degrees C in age-matched monkeys subjected to 6 years of a 30% reduction in caloric intake. A short-term (1 month) 30% restriction of 2.5-year-old monkeys lowered subcutaneous body temperature by 1.0 degrees C. Indirect calorimetry showed that 24-hr energy expenditure was reduced by approximately 24% during short-term CR. The temporal association between reduced body temperature and energy expenditure suggests that reductions in body temperature relate to the induction of an energy conservation mechanism during CR. These reductions in body temperature and energy expenditure are consistent with findings in rodent studies in which aging rate was retarded by CR, now strengthening the possibility that CR may exert beneficial effects in primates analogous to those observed in rodents.

    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 (age(2)). 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.

    The daytime Arietid meteor shower is active from mid-May to late June and is amongst the strongest of the annual meteor showers, comparable in activity and duration to the Perseids and the Geminids. Due to the daytime nature of the shower, the Arietids have mostly been constrained by radar studies. The Arietids exhibit a long-debated discrepancy in the semi-major axis and the eccentricity of meteoroid orbits as measured by radar and optical surveys. Radar studies yield systematically lower values for the semi-major axis and eccentricity, where the origin of these discrepancies remain unclear. The proposed parent bodies of the stream include comet 96P/Machholz [McIntosh, B.A., 1990. Comet P/Machholz and the Quadrantid meteor stream. Icarus 86, 894 299-304. doi:10.1016/0019-1035(90)90219-Y.] and more recently a member of the Marsden group of sun-skirting comets, P/1999 J6 [Sekanina, Z., Chodas, P.W., 2005. Origin of the Marsden and Kracht Groups of Sunskirting 922 Comets. I. Association with Comet 96P/Machholz and Its Interplanetary Complex. ApJS 923 161, 551-586. doi:10.1086/497374.]. In this work, we present detailed numerical modelling of the daytime Arietid meteoroid stream, with the goal to identifying the parent body and constraining the age of the stream. We use observational data from an extensive survey of the Arietids by the Canadian Meteor Orbit Radar (CMOR), in the period of 2002-2013, and several optical observations by the SonotaCo meteor network and the Cameras for All-sky Meteor Surveillance (CAMS). We find the most plausible scenario to be that the age and the formation mechanism of the Arietids is consistent with continuous cometary activity of 96P/Machholz over a time interval of ≈12,000 years. The sun-skirting comet P/1999 J6 suggested by [Sekanina, Z., Chodas, P.W., 2005. Origin of the Marsden and Kracht Groups of Sunskirting 922 Comets. I.

    Eating attitudes and body image have been studied in a group of 109 girls, pupils of the fifth primary school grade (average age 10 years and 8 months). The Children's Eating Attitude Test (ChEAT) has been used in the study of eating attitudes. The mean questionnaire score is 11.38 +/- 8 with a range of 0 to 45. Fourteen girls (12.8%) had a total score higher than 20, making them an eating disorder risk group. A set of seven schematic figures showing silhouettes of girls ranging from very thin to very heavy has been used in the study of body image perception. The girls were supposed to indicate the figure having the highest resemblance to their own figure (self figure), and the figure they would like to have (ideal self figure). The mean value of the current figure was 4.28, and that of the ideal figure 3.95. Satisfaction with their figure was expressed by 46.79% of the girls; 39.45% wanted to be thinner, and 13.45% to be heavier. When these data were compared with BMI, 27.52% (of the total) of the girls wanting to be thinner were found to have a normal BMI, and 11.93% a > 95 centile BMI. Among the girls satisfied with their figure 2 had a low and 2 a high BMI, while 43.12% were within the normal BMI range. Out of the 13.45% of girls wanting to be heavier, 6.42% (of the total) had a low BMI, 6.42% a normal BMI, and 0.92% (one girl) a > 95 centile BMI. The girls were divided into two groups in terms of the ChEAT score: ChEAT+ (anorexia risk) and ChEAT-. The groups differed in terms of body weight and BMI (the ChEAT+ group was heavier); ChEAT+ girls tended to prefer a thinner figure and experienced themselves as being heavier.

    In Science May 11 2001 (p.1142-1145), Kusky et al. reported an ophiolite complex of late Archean age in the Dongwanzi area of the North China Craton, which has subsequently been considered a hallmark for Archean plate tectonics. However, this interpretation has been questioned because no convincing pillow lavas or sheeted dikes have been found in the Dongwanzi complex and, more importantly, as a major part of the ophiolite complex, the Dongwanzi ultramafic-mafic body has not previously been dated and it therefore remains unknown whether it is of Archean age. In this study, we carried out detailed field investigations and SHRIMP U-Pb zircon dating on the rocks of the Dongwanzi ultramafic-mafic body, as recognized by Kusky et al. Our field observations reveal that in several places along the boundaries of the Dongwanzi body, mafic dikes emanating from the main body intrude the country rocks of the unmetamorphosed Mesoproterozoic sedimentary successions of the Changcheng-Jixian 'System'. One of these dikes yielded a SHRIMP U-Pb zircon age of 306 ± 6 Ma, similar to the SHRIMP U-Pb zircon age of 308 ± 4 Ma obtained from a plagioclase-bearing pyroxenite from the Dongwanzi ultramafic-mafic body. Four other samples collected from various parts of the ultramafic-mafic body (gabbro, leucogabbro or pyroxenite) record similar SHRIMP U-Pb zircon ages around ˜ 300 Ma. Therefore, both field relationships and SHRIMP U-Pb zircon dating results unequivocally demonstrate that the Dongwanzi ultramafic-mafic body is not part of an Archean ophiolite.

    The tree shrew (Tupaia belangeri chinensis) is a squirrel-like lower primate or a close relative of primates, commonly used as an animal model in biomedical research. Despite more than three decades of usage in research, the clear relationships between body weight, fasting blood glucose concentration, sex and age among tree shrews remain unclear. Based on an investigation of 992 tree shrews (454 males and 538 females) aged between 4 months and 4 years old, we found that male tree shrews have significantly higher body weight and fasting blood glucose concentration than female tree shrews (p < 0.001). The concentration of fasting blood glucose slightly increased with body weight in males (r = 0.152, p < 0.001). Meanwhile, in females, the body weight, concentration of fasting blood glucose and waist circumference positively increased with age (p < 0.001). Additionally, 17 tree shrews with Lee index [body weight (g)*0.33*1000/body length (cm)] above 290 had significantly higher body weight, waist circumference and glycated haemoglobin A1c (HbA1c) than non-obese tree shrews with a Lee index score below 290 (p < 0.001). Interestingly, 6 of 992 tree shrews (three males and three females, 2-4 years old) displayed impaired plasma triglycerides, HbA1c, low-density lipoprotein and oral glucose tolerance test, suggestive of the early symptoms of metabolic syndrome. This study provides the first clear relationships between body weight, fasting blood glucose concentration, sex and age in tree shrews, further improving our understanding of this relationship in metabolic syndrome (MetS). Given the similarity of tree shrews to humans and non-human primates, this finding supports their potential use as an animal model in the research of MetS.

    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.

    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

    The biologic actions of endogeneous growth hormone (GH) depend on its secretion and clearance rates as well as sensitivity at the receptor level. Aberrations in GH pharmacokinetics and pharmacodynamics may occur with increasing age, and have been implicated in diseases such as obesity, diabetes mellitus, and critical illness. In this review, recent insights into the association between GH metabolism and age, body composition, binding proteins and other hormones are discussed.

    This study assessed age-related changes in body composition (specifically in trunk fat and appendicular lean masses), with consideration of body mass index (BMI) at age 20 years (BMI reference age, “BMIref”), ethnicity and lifetime weight change history. A cross-sectional dual-energy X-ray absorptiometry-based dataset was extracted from the U.S. National Health and Nutrition Examination Survey (NHANES) 1999–2004. Only European-American and African-American subjects were used (2705 men, 2527 women). For each gender and ethnicity, 6 analytic cases were considered, based on three BMIref categories (normal, overweight and obese, being 22, 27 and 30 kg/m2, respectively) and two weight contexts (stable weight or weight gain across the lifespan). A nonparametric model was developed to investigate age-related changes in body composition. Then, parametric modelling was developed for assessing BMIref- and ethnicity-specific effects during aging. In the stable weight, both genders’ and ethnicities’ trunk fat (TF) increased gradually; body fat (BF) remained stable until 40 years and increased thereafter; trunk lean (TL) remained stable, but appendicular lean (APL) and body lean (BL) declined from 20 years. In the weight gain context, TF and BF increased at a constant rate, while APL, TL and BL increased until 40–50 years, and then declined slightly. Compared with European-American subjects of both genders, African-American subjects had lower TF and BF masses. Ethnic differences in body composition were quantified and found to remain constant across the lifespan. PMID:27529269

    Insulin-induced gene 2 (INSIG2) plays an important role in the regulation of cholesterol and fatty acids synthesis. A polymorphism, rs7566605, located 10 kilobases upstream of the INSIG2 gene, was identified in a genomewide association study of obesity. We conducted an association study of 12 INSIG2 tag-single nucleotide polymorphisms with longitudinal measures of body size (body mass index and waist circumference) and lipid metabolism (plasma high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglycerides levels). We investigated their interaction with age in 4304 Coronary Artery Risk Development in Young Adults participants (49.5% blacks, 50.5% whites) followed prospectively for 20 years. rs7566605 was not associated with variation in body size or lipid metabolism at any age in either racial group. However, rs1352083 and rs10185316 were associated with age-related decline in high-density lipoprotein cholesterol in whites (P = .0005 and .04, respectively). A similar trend was observed in blacks who consistently maintained a body mass index less than 25 kg/m(2) over the study period. These data support a role of INSIG2 sequence variation in the regulation of cholesterol metabolism.

    2003-01-01

    The present study answers the question on how the human body changes in two successive decades after its final height had been reached. One hundred and three individuals (56 males and 47 females) who were followed up longitudinally by a team of scientists from birth to 18 years of age were investigated anthropometrically by 18 body measurements again when they reached the age of between 35 and 39 years. The Carter-Heath somatotype was ascertained as a part of the study. The results of the investigation at the age of 35 to 39 years were compared with the Czech Standard and with those from 18 years of age. The means of all measurements in both sexes increased with age (with the exception of stature in females). Relative measurements and indices, which were calculated only in the groups of 35-39 year-olds were all on the average greater in males than in females with the exception of relative head circumferences and pelvis width, in the pelvis width in per cent of biacromial width, in the sum of skinfolds, and in the gross percent of body fat. Males as well as females increased from the age of 18 to 35-39 as a rule in weight, muscle, bone and fat mass, which were manifested by a shift towards endomorphic and mesomorphic components of their somatotypes away from the ectomorphic one.

    Extensive measurements of calf body temperature are limited in the literature. In this study, body temperatures were collected by taping a data logger to the skin over the tail vein opposing the rectum of Holstein calves between 4 and 60d of age during 3 different periods of the summer and fall. The summer period was separated into moderate (21-33°C average low to high) and hot (25-37°C) periods, whereas the fall exhibited cool (11-19°C) ambient temperatures. Tail temperatures were compared in a mixed model ANOVA using ambient temperature, age of calf, and time of day (10-min increments) as fixed effects and calf as a random effect. Measures within calf were modeled as repeated effects of type autoregressive 1. Calf temperature increased 0.0325°C (±0.00035) per 1°C increase in ambient temperature. Body temperature varied in a distinct, diurnal pattern with time of day, with body temperatures being lowest around 0800h and highest between 1700 and 2200h. During periods of hot weather, the highest calf temperature was later in the day (~2200h). Calf minimum, maximum, and average body temperatures were all higher in hot than in moderate periods and higher in moderate than in cool periods.

    2015-01-01

    Context Studies on 24-hour growth hormone (GH) secretion are rare. The influence of sex, age and adiposity are well recognized but generally derived from specific selected subject groups, not spanning sexes, many age decades, and a range of body weights. Objective The goal was to investigate GH dynamics in a group of 130 healthy adult subjects, both men and women, across 5 age decades, and a 2.5 fold range of body mass index (BMI). Methods GH was measured by a sensitive immunofluorometric assay. Secretion parameters were quantified by automated deconvolution and relative pattern randomness by approximate entropy (ApEn). Results Median age was 40, range 20–77 year. Median BMI was 26, range 18.3–49.8 kg/m2. Pulsatile 24-hour GH secretion was negatively correlated with age (P=0.002) and BMI (P<0.0001). Basal GH secretion negatively correlated with BMI (P=0.003) and not with age. The sex-dependent GH secretion (larger in women) was no longer detectable after 50 year. IGF-1 levels were lower in women after 50 year compared with men of similar age. ApEn showed age-related increase in both sexes and was higher in premenopausal and postmenopausal women than men of comparable age (P<0.0001). A single fasting GH measurement is non-informative of 24-hour GH secretion. Conclusion BMI dominates the negative regulation of 24-hour GH secretion across 5 decades of age in this till now largest cohort of healthy adults, who underwent 24-hour blood sampling. Sex also impacts GH secretion before age 50 yr and its regularity at all ages. Serum IGF-I differences partly depend on pre- or postmenopausal state. Finally, a single GH measurement is not informative of 24-hour GH secretion. PMID:26228064

    The uptake of uranium-235 and plutonium-239 in mice of different age and sex is examined in a controlled study. The animals received a single intraperitoneal dose of either plutonium-239 nitrate or uranium-235 nitrate at amounts of 0.2 mg/kg and 1.0 mg/kg respectively. Seven days after radioisotope administration, the animals were sacrificed and the uranium or plutonium content of the hair (including skin) was measured directly by delayed neutron analysis. Results show a higher retention of both uranium and plutonium in the whole body of young animals, but for specific whole body burden there was a marked increase with age for plutonium and only a slight increase for uranium. Sex did not appear to have any significant influence on the residual whole body or hair burdens. (JMT)

    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.

    Excessive weight gain in adults is associated with a variety of negative health outcomes. Unfortunately, dieting, exercise, and pharmacological interventions have had limited long-term success in weight control and can result in detrimental side effects, including accelerating age-related cancellous bone loss. We investigated the efficacy of using hypothalamic leptin gene therapy as an alternative method for reducing weight in skeletally-mature (9 months old) female rats and determined the impact of leptin-induced weight loss on bone mass, density, and microarchitecture, and serum biomarkers of bone turnover (CTx and osteocalcin). Rats were implanted with cannulae in the 3rd ventricle of the hypothalamus and injected with either recombinant adeno-associated virus encoding the gene for rat leptin (rAAV-Leptin, n=7) or a control vector encoding green fluorescent protein (rAAV-GFP, n=10) and sacrificed 18 weeks later. A baseline control group (n=7) was sacrificed at vector administration. rAAV-Leptin-treated rats lost weight (-4±2%) while rAAV-GFP-treated rats gained weight (14±2%) during the study. At study termination, rAAV-Leptin-treated rats weighed 17% less than rAAV-GFP-treated rats and had lower abdominal white adipose tissue weight (-80%), serum leptin (-77%), and serum IGF1 (-34%). Cancellous bone volume fraction in distal femur metaphysis and epiphysis, and in lumbar vertebra tended to be lower (P<0.1) in rAAV-GFP-treated rats (13.5 months old) compared to baseline control rats (9 months old). Significant differences in cancellous bone or biomarkers of bone turnover were not detected between rAAV-Leptin and rAAV-GFP rats. In summary, rAAV-Leptin-treated rats maintained a lower body weight compared to baseline and rAAV-GFP-treated rats with minimal effects on bone mass, density, microarchitecture, or biochemical markers of bone turnover.

  8. Body weight, eating patterns, and physical activity: the role of education.

    PubMed

    Atella, Vincenzo; Kopinska, Joanna

    2014-08-01

    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.

    Middle age is associated with a pronounced decline in power and flexibility. Whilst whole-body vibration training (WBVT) improves performance in a range of populations, whether WBVT can improve muscle power and flexibility in a middle-aged population is not known. The present study aimed to determine the influence of 5 weeks progressive WBVT in middle-aged (45-55 years) and younger (20-30 years) recreationally active females. Participants in each age group were randomly allocated to an intervention (WBVT) or control group. The WBVT groups trained for 5 weeks on a vibration platform, while the control groups performed identical exercises, with no vibration. Prior to, and after, the 5-week study vertical countermovement jump (VCMJ) and range of motion (ROM) performance were measured. WBVT significantly (p = 0.001) improved VCMJ performance when compared to the control groups. This improvement was significantly (p = 0.001) greater in the middle-aged compared with the younger WBVT group. WBVT significantly (p = 0.001) improved ROM irrespective of age. Taken together, these results suggest that WBVT can off-set age related performance decrements, which has therapeutic implications for musculoskeletal aging. Therefore, WBVT could be undertaken to minimise age-related performance deterioration in middle-aged female populations.

    Although ageing people could benefit from healthy diet and physical activity to maintain health and quality of life, further understandings of the diet- and physical activity-related mechanisms that may cause changes in health and quality of life perception are necessary. The purpose of the study was to investigate the effect of eating attitudes, body mass and image satisfaction, and exercise dependence in the relationship between physical activity and health and quality of life perception in older individuals. Hundred and seventy-nine late middle-aged, (55–64 yrs), young-old (65–74 yrs), and old (75–84 yrs) senior athletes (n = 56), physically active (n = 58) or sedentary adults (n = 65) were submitted to anthropometric evaluations (body mass, height) and self-reported questionnaires: Body Image Dimensional Assessment, Exercise Dependence Scale, Eating Attitude Test, and Short Form Health Survey (Physical Component Summary [PCS] and Mental Component Summary [MCS] of and health and quality of life perception). Senior athletes, physically active, and sedentary participants subgroups differed (P<0.05) from each other in body mass index (BMI) and several components of body image and exercise dependence. Senior athletes showed, compared to their sedentary counterparts, further differences (P<0.05) in eating attitudes and in both PCS and MCS. Mediation analysis showed that the relationship between physical activity habit and MCS, but not PCS, was indirectly explained by a serial mediation chain composed of objective BMI and subjective body image (dis)satisfaction. Findings confirm the relevant role of physically active life habits for older individuals to perceive good physical and mental health. The novelty of the three-path mediated link between physical activity level and mental health perception suggests that the beneficial effect of a physically active lifestyle on weight control can positively impinge on the cognitive-emotional dimension of mental health by

    Brown adipose tissue (BAT) can be identified by (18)F-fluorodeoxyglucose (FDG)-positron emission tomography (PET) combined with X-ray computed tomography (CT) in adult humans. The objective of this study was to clarify the relationship between BAT and adiposity in healthy adult humans, particularly to test the idea that decreased BAT activity may be associated with body fat accumulation with age. One hundred and sixty-two healthy volunteers aged 20-73 years (103 males and 59 females) underwent FDG-PET/CT after 2-h cold exposure at 19 °C with light clothing. Cold-activated BAT was detected in 41% of the subjects (BAT-positive). Compared with the BAT-negative group, the BAT-positive group was younger (P < 0.01) and showed a lower BMI (P < 0.01), body fat content (P < 0.01), and abdominal fat (P < 0.01). The incidence of cold-activated BAT decreased with age (P < 0.01), being more than 50% in the twenties, but less than 10% in the fifties and sixties. The adiposity-related parameters showed some sex differences, but increased with age in the BAT-negative group (P < 0.01), while they remained unchanged from the twenties to forties in the BAT-positive group, in both sexes. These results suggest that decreased BAT activity may be associated with accumulation of body fat with age.

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.

    Resting and peak glucose, insulin, glucagon, gastric inhibitory polypeptide (GIP) and pancreatic polypeptide (PP) levels were evaluated pretraining, 3 weeks and 10 weeks posttraining in seven college age males. The exercise consisted of thrice weekly session of jogging at 70% VO2max for 20 minutes plus warmup and cool down. Following the 10 weeks, VO2max increased significantly. Body weight remained constant and body fat decreased significantly. Fasting and peak blood glucose levels were normal at the beginning of the study yet improved with training. As expected, fasting and peak insulin levels decreased significantly with training. Although GIP did not change significantly with training, an uncoupling of GIP and insulin peak responses was observed. Glucagon levels were essentially unchanged. Fasting and peak PP levels increased slightly as training occurred. These hormone responses suggest that perhaps body weight and/or changes in body fat stores and fuel use might influence peptide hormone responses with training.

    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 present aim was to investigate the effect of age and education on the moral reasoning of the same 535 individuals in sports for whom nature of sport experience was reported. All 535 participants (M age = 24.9 yr., SD = 8.3) were involved in sports at the time of the study as athletes (n = 342), referees (n = 145), or coaches (n = 48), and had a wide range of education. Analysis of variance of scores on the Defining Issues Test of Rest showed moral judgment in sports differs significantly amongst different age groups (F5.510 = 5.37, p < .001) and amounts of education (F4.511 = 6.24, p < .001). Generally, with more education, higher moral judgment can be expected. It is apparent that moral development in sport is related to age and education, as also holds for a wider social setting.

    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.

    The present study was undertaken to assess the relationship between the scrotal circumference and testicular parameters with body weight and age in Tho Tho bulls (Bos indicus), which were maintained at around the villages of National Research Centre on Mithun (ICAR), Jharnapani, Nagaland, India. A total of 32 Tho Tho bulls were selected and divided into four groups according to their age and each group consisted of 8 bulls, namely, Group I: 18–24 months (n = 8), Group II: 25–36 months (n = 8), Group III: 37–48 months (n = 8), and Group IV: 49 months and above (n = 8). The scrotal circumference and testicular parameters were measured with caliper and tape and age of animals was calculated with dental formula. The body weight of bulls was estimated with Shaeffer's formula. Result revealed that the scrotal circumference was highly correlated with testicular parameters and body weight compared to age. Compared to exotic cattle (Bos taurus), Tho Tho bull's testicular parameters and scrotal circumference were lower. The results of the present study in Tho Tho bulls revealed that scrotal circumference is a useful indicator and is an important selection criterion to determine the testicular development and breeding soundness in young bulls as it is highly correlated with tesicular parameters.

    At old age, humans generally have declining muscle mass and increased fat deposition, which can increase the risk of developing cardiometabolic diseases. While regular physical activity postpones these age-related derangements, this is not always possible in the elderly because of disabilities or risk of injury. Whole-body vibration (WBV) training may be considered as an alternative to physical activity particularly in the frail population. To explore this possibility, we characterized whole-body and organ-specific metabolic processes in 6-month and 25-month old mice, over a period of 14 weeks of WBV versus sham training. WBV training tended to increase blood glucose turnover rates and stimulated hepatic glycogen utilization during fasting irrespective of age. WBV was effective in reducing white fat mass and hepatic triglyceride content only in old but not in young mice and these reductions were related to upregulation of hepatic mitochondrial uncoupling of metabolism (assessed by high-resolution respirometry) and increased expression of uncoupling protein 2. Because these changes occurred independent of changes in food intake and whole-body metabolic rate (assessed by indirect calorimetry), the liver-specific effects of WBV may be a primary mechanism to improve metabolic health during aging, rather than that it is a consequence of alterations in energy balance.

    This study investigated the relationship between education and physical activity and the difference between a physiological prediction of age and chronological age. Cortical and subcortical grey matter regional volumes were calculated from 331 healthy adults (range: 19-79 years). Multivariate analyses identified a covariance pattern of brain volumes best predicting chronological age (CA)(R2 = 47%). Individual expression of this brain pattern served as a physiologic measure of brain age (BA). The difference between CA and BA was predicted by education and self-report measures of physical activity. Education and the daily number of flights of stairs climbed were the only two significant predictors of decreased brain age. Effect sizes demonstrated that brain age decreased by 0.95 years for each year of education and by 0.58 years for one additional daily FOSC. Effects of education and FOSC on regional brain volume were largely driven by temporal and subcortical volumes. These results demonstrate that higher levels of education and daily FOSC are related to larger brain volume than predicted by chronological age which supports the utility of regional grey matter volume as a biomarker of healthy brain aging.

    Body segment parameters are required when researching joint kinetics using inverse dynamics models. However, the only regression equations for estimating pediatric body segment parameters across a wide age range were developed, using photogrammetry, based on 12 boys and have not been validated to date (Jensen, R.K., 1986. Body segment mass, radius and radius of gyration proportions of children. Journal of Biomechanics 19, 359-368). To assess whether these equations could validly be applied to girls, we asked whether body segment parameters estimated by the equations differ from parameters measured using a validated magnetic resonance imaging (MRI) method. If so, do the differences cause significant differences in joint kinetics during normal gait? Body segment parameters were estimated from axial MRIs of the left thigh and shank of 10 healthy girls (9.6 +/- 0.9 years) and compared to those from Jensen's equations. Kinematics and kinetics were collected for 10 walking trials. Extrema in hip and knee moments and powers were compared between the two sets of body segment parameters. With the exception of the shank mass center and radius of gyration, body segment parameters measured using MRI were significantly different from those estimated using regression equations. These systematic differences in body segment parameters resulted in significant differences in sagittal-plane joint moments and powers during gait. Nevertheless, it is doubtful that even the greatest differences in kinetics are practically meaningful (0.3% BW x HT and 0.7% BW x HT/s for moments and power at the hip, respectively). Therefore, body segment parameters estimated using Jensen's regression equations are a suitable substitute for more detailed anatomical imaging of 8-10-year-old girls when quantifying joint kinetics during gait.

    Detailed neurological examinations and body sway measurements with a stable force measuring platform were carried out on 30 healthy adults between 21 and 63 years of age. The results were analyzed for sex- and age-associated changes with regard to three different sway components (total sway, anterio-posterior sway, lateral sway) and two different conditions (eyes open, eyes closed). Sex-associated differences were highly significant for all sway components in the oldest age group (51-65 years) in which men exhibited more spontaneous postural sway than women in the condition eyes open. With eyes closed these differences increased. Middle-aged men (36-50 years) also exhibited significantly more postural sway than women of the same age. In the condition eyes open especially total sway and anterioposterior sway were increased, whereas in the condition eyes closed total sway and lateral sway were predominantly higher in men than in women. In the youngest age group (21-35 years) no sex-related differences in postural sway were found. Age-associated differences were significant for anterioposterior sway (eyes open) in men, increasing continuously from the young to the middle-aged, and again from the middle-aged to the older age group. Anterioposterior sway in women, on the contrary, did not change with age. Age-associated differences in women were found for total sway (eyes open) and lateral sway (eyes closed). However, the highest values for total sway and lateral sway within the female group were obtained from young women in both conditions eyes open and eyes closed.(ABSTRACT TRUNCATED AT 250 WORDS)

  16. 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.

    Gestational age (GA) is thought to affect height growth in small-for-gestational age (SGA) children. However, the GA-specific trajectories in body mass index (BMI) and early appearances of adiposity rebound (AR) have not been fully investigated in a cohort of Japanese SGA children. A longitudinal cohort study was conducted with 1063 SGA children born in Kobe, Japan, with sufficient records from birth to 3 years of age. Subjects were divided into subgroups based on GA: 39–41 weeks GA (n = 723), 37–38 weeks GA (n = 256), 34–36 weeks GA (n = 62), and <34 weeks GA (n = 22). Height and BMI were assessed at 4 months, 9 months, 1.5 years, and 3 years of age. The catch-up rate for height was GA-dependent. Most children with 39–41 weeks GA (91%) caught up by 4 months of age; however, lower GA was associated with a slower elevation in the catch-up rate. The BMI trajectory during the first 3 years was also GA-dependent, with a change in GA dependency at a boundary of 37 weeks GA. Approximately 7% of SGA children had already developed AR before 3 years of age. In conclusion, growth patterns during infancy and early childhood in SGA children differ depending on GA.

    The substantial role of computational approaches to physics research is not currently reflected proportionately in how we prepare future physicists. We can do better in using computation to teach the concepts of physics --Computational (Physics Education) -- and to prepare students to be computational physicists -- (Computational Physics) Education. We have the opportunity to demonstrate that effective use of computing in physics really matters. A computational approach in physics education is essential because quantitative reasoning, computational thinking, and multiscale modeling are the intellectual ``heart and soul'' of 21st Century physics and therefore are the essential skills of the 21st Century physicist. Computing matters because we can apply the power of interactive computing to reach a deeper understanding of physics and the mathematics underlying the theory and their role in understanding the world. We will explore a transformation in physics education, supported by interactive computing resources, promoting a dynamic encounter with the world through guided discovery. We will explore a variety of free and low-cost sources for modeling tools from Shodor and its Computational Science Education Reference Desk, a pathway project of the National Science Digital Library.

    For the last 38 years, Mini Mental State Examination (MMSE) has been widely used as a dementia screening measure in everyday clinical practice as well as in both cohort and cross-sectional studies. Its validity and reliability for the Greek population has explicitly been documented. However, the effect of age and education on the subject's performance makes it necessary to reckon them in the estimation of the "cutoff score". The purpose of this study is to estimate the prevalence of dementia in Greek population and determine the "cutoff score" by age and education-corrected norms. Cross sectional study of 630 patients older than 55 years, who live independently in Ilion and Helioupolis Municipalities was conducted, 27.3% of the subjects tested in the study were diagnosed with memory disorder according to their MMSE scores and the validation for the Greek population. The effect of age and education to the subjects' performance was statistically significant (p=.000). The use of standard "cutoff score" was not proved to be useful for the personalized interpretation of the results, as documented by the fact that older individuals with lower education had a poorer performance relatively to younger, highly educated subjects. Comparatively to the group age of 55-60 years, the odds ratio after the age of 75 years varies from 2.58 to 4.91. Regarding the variable factor of education, the odds ratio for the first degree education graduates decreases from 1.43 to 3.19 for the third degree education graduates in comparison with the group of illiterates. In conclusion, the use of the "cutoff score" algorithm and the simultaneous estimation of age and education effect on MMSE score may prove useful for the proper evaluation of MMSE performance. According to the age and education of examine candidates in the community and the primary care, we propose the use of the 25th percentile as a more useful cutoff score in order to decrease the false positive results.

    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

    Numerous studies have identified the effects of prematurity on the neonate's physical health, however few studies have explored the effects of prematurity on both the physical and mental health of the child as they develop. Secondary analysis of data from the Millennium Cohort Study, a longitudinal study of infants (n = 18 818, born 2000-2002 in the United Kingdom) was performed. Effects of gestational age at birth on health outcomes at 5 years were measured using parental rating of their children's general health and severity of behavior problems. The association between parent's general health ratings and behavior problem ratings was low: 86% of those reporting serious behavior problems (5% of the sample, n = 764) rated their child as being in excellent, very good, or good health. Still, a gradient of increasing risk of poorer outcome with decreasing gestational age was observed for a composite health measure (poor/fair health and/or serious behavior problems), suggesting an association with prematurity for this composite assessment of health status. The greatest contribution to the childhood composite health measure at 5 years was for children born at 32-36 weeks gestation: population attributable fractions for having poor outcomes was 3.4% (Bonferroni-adjusted 95% confidence interval 1.1%-6.2%), compared to 1% (0.2-2.3) for birth at less than 32 weeks. Results suggest that preterm children, by school entry, are not only at high risk of physical health problems, but also of behavioral health problems. The recognition of, and response to comprehensive health and well-being outcomes related to prematurity are important in order to correctly plan and deliver adequate paediatric health services and policies.

    Data were collected prospectively on parameters related to first calving on 18 farms located in Northeastern Pennsylvania. This project was designed to study possible residual effects of calf management practices and events occurring during the first 16 wk of life on age, BW, skeletal growth, and body condition score at first calving. Multiple imputation method for handling missing data was incorporated in these analyses. This method has the advantage over ad hoc single imputations because the appropriate error structure is maintained. Much similarity was found between the multiple imputation method and a traditional mixed model analysis, except that some estimates from the multiple imputation method seemed more logical in their effects on the parameter measured. Factors related to increased age at first calving were increased difficulty of delivery, antibiotic treatment of sick calves, increased amount of milk or milk replacer fed before weaning, reduced quality of forage fed to weaned calves, maximum humidity, mean daily temperature, and maximum ammonia levels in calf housing areas. Body weight at calving tended to increase with parity of the dam, increased amount of grain fed to calves, increased ammonia levels, and increased mean temperature of the calf housing area. Body condition score at calving tended to be positively influenced by delivery score at first calving, dam parity, and milk or milk replacer dry matter intake. Withers height at calving was positively affected by treatment of animals with antibiotics and increased mean temperature in the calf area. This study demonstrated that nutrition, housing, and management factors that affect health and growth of calves have long-term effects on the animal at least through first calving.

    Piglet body composition at weaning could be a determinant for pig's viability and may be influenced by factors such as the nutritional management followed during suckling. An experiment was conducted to study whether intermittent suckling (IS) affects body composition at weaning and nutrient and energy retention during a 34-day lactation period in Iberian piglets. Litters were subjected to conventional suckling (CS) or IS (n=10 litters of six piglets per treatment) in two trials. All piglets had ad libitum access to creep feed from day 15 onwards. In IS, piglets were progressively separated from the sow for 6, 8 and 10 h daily during the last week of lactation, whereas in CS piglets had continuous access to their dams. Creep feed intake in litters and BW development of individual piglets were measured throughout the 34-day lactation. Within each litter, both at birth and at weaning (day 35), one piglet was used to assess nutrient retention and body composition by the comparative slaughter approach. During days 29 to 35 of the experiment, daily creep feed intake was greater in IS piglets (IS 124, CS 67 g/piglet, P=0.040), and average daily gain differed significantly between groups (IS 190, CS 150 g/day, P=0.010). BW at weaning was higher in the IS than in the CS piglets (IS 8.19, CS 7.48 kg, P=0.011). Empty-body fat and energy content at weaning were higher in the IS compared with CS litters, as well as fat content in the carcass (P=0.04). The IS treatment did not affect empty-body protein deposition, but significantly increased daily retention of fat, energy, ash and calcium, compared with CS litters (P<0.05). Thus, IS in Iberian piglets seems to enhance feed intake, growth rate and retention of some body components, which may contribute to a higher body fat content at weaning and facilitate the weaning process.

    The 'Mean Residence Time' (MRT) of groundwater is required to develop reliable hydrogeological concepts of groundwater bodies as a prerequisite for a qualified monitoring and risk assessment. MRTs from monitoring wells help to assess if groundwater bodies are 'at risk' or 'not at risk' failing to meet good groundwater quantitative and chemical status according to the Water Framework Directive and therefore not being able to use the groundwater as drinking water or industrial water resource. A combination of 18O/2H, 3H, 3H/3He and in some cases additional CFC, SF6, 85Kr and 35S measurements allow to calculate reliable MRTs in 20 groundwater bodies covering 13% (approx.10719 km2) of the Austrian territory. Altogether 401 groundwater wells and springs from the existing groundwater monitoring network were analysed for δ18O (n=1500), 3H (n=800) and 3He (n=327) since 2006. Considering both the fact that monitoring wells may have multiple or long well screens and the inherent uncertainties of groundwater age dating techniques, age estimations were classified into 5 categories of short ( 50years) mean residence times for each monitoring site. Subsequently, median values of the MRT categories were assigned to each investigated groundwater body. These are valuable information to fix extraction rates, to set measures to improve the land use and groundwater protection and to validate hydrogeological concepts. Generally, MRTs of groundwater bodies increase from shallow Alpine groundwater bodies over deeper Alpine valley-aquifers to longer MRTs in the Pannonian climate range in the east of Austria.

    Background The apolipoprotein E (APOE) gene is polymorphic, encoding one of 3 common alleles (ε2, ε3, ε4) produced from combinations of 2 non-synonymous SNPs (rs429358 and rs7412). APOE plays an important role controlling plasma lipids but its association with adipocyte functionality and body fatness remains to be determined. Methods We analyzed fasting plasma lipids and genotyped the two main APOE-SNPs (rs429358 and rs7412), both located in the fourth exon of the APOE, in 4660 Caucasian middle-aged men free of cardiovascular disease. Results The rs7412 SNP, which determines the APOE2 isoform, was significantly associated with Body Mass Index (BMI) and Waist Girth (WG) in a multivariate model accounting for age, smoking status and plasma lipids. BMI and WG were highest in TT homozygotes and lowest in CC homozygotes. This effect was independent of the rs429358 SNP, which failed to show any association with the BMI and WG variables. The odds ratio of being obese (BMI>30) for individuals carrying the APOε2 allele, present in 14% of the cohort and defined by the rs7412 SNP, was also significant in this multivariate model, with an OR of 1.27 (95% CI: 1.01–1.59). Conclusions This study provides an evidence of a lipid-independent association between the APOE SNP rs7412 and body fatness surrogates, BMI and WG, in a large cohort of middle-aged males.

    An inverse relationship between educational level and dementia has been reported in several studies. In this study we investigated the relationship between educational level and dementia related deaths for cohorts of people all born during 1915-39. The cohorts were followed up from adulthood or old age, taking into account possible confounders and mediating paths. Our study population comprised participants in Norwegian health examination studies in the period 1974-2002; The Counties Study and Cohort of Norway (CONOR). Dementia related deaths were defined as deaths with a dementia diagnosis on the death certificate and linked using the Cause of Death Registry to year 2012. The study included 90,843 participants, 2.06 million person years and 2440 dementia related deaths. Cox regression was used to assess the association between education and dementia related deaths. Both high and middle educational levels were associated with lower dementia related death risk compared to those with low education when follow-up started in adulthood (35-49 years, high versus low education: HR=0.68, 95% confidence interval (CI) 0.50-0.93; 50-69 years, high versus low education: HR=0.52, 95% CI 0.34-0.80). However, when follow-up started at old age (70-80 years) there was no significant association between education and dementia related death. Restricting the study population to those born during a five-year period 1925-29 (the birth cohort overlapping all three age groups), gave similar main findings. The protective effects found for both high and middle educational level compared to low education were robust to adjustment for cardiovascular health and life style factors, suggesting education to be a protective factor for dementia related death. Both high and middle educational levels were associated with decreased dementia related death risk compared with low educational level when follow-up started in adulthood, but no association was observed when follow-up started at old age.

    Background: Recent studies have claimed a positive effect of physical activity and body composition on vagal tone. In pediatric populations, there is a pronounced decrease in heart rate with age. While this decrease is often interpreted as an age-related increase in vagal tone, there is some evidence that it may be related to a decrease in intrinsic heart rate. This factor has not been taken into account in most previous studies. The aim of the present study was to assess the association between physical activity and/or body composition and heart rate variability (HRV) independently of the decline in heart rate in young children. Methods: Anthropometric measurements were taken in 309 children aged 2-6 years. Ambulatory electrocardiograms were collected over 14-18 h comprising a full night and accelerometry over 7 days. HRV was determined of three different night segments: (1) over 5 min during deep sleep identified automatically based on HRV characteristics; (2) during a 20 min segment starting 15 min after sleep onset; (3) over a 4-h segment between midnight and 4 a.m. Linear models were computed for HRV parameters with anthropometric and physical activity variables adjusted for heart rate and other confounding variables (e.g., age for physical activity models). Results: We found a decline in heart rate with increasing physical activity and decreasing skinfold thickness. HRV parameters decreased with increasing age, height, and weight in HR-adjusted regression models. These relationships were only found in segments of deep sleep detected automatically based on HRV or manually 15 min after sleep onset, but not in the 4-h segment with random sleep phases. Conclusions: Contrary to most previous studies, we found no increase of standard HRV parameters with age, however, when adjusted for heart rate, there was a significant decrease of HRV parameters with increasing age. Without knowing intrinsic heart rate correct interpretation of HRV in growing children is

    AIMS—To compare the effects of early and delayed sodium supplementation on body composition and body water compartments during the first two weeks of postnatal life.
METHODS—Preterm infants of 25-30 weeks' gestation were stratified and randomly assigned according to gender and gestational age, to receive a sodium intake of 4 mmol/kg/day beginning either on the second day after birth or when weight loss of 6% of birthweight had been achieved. Daily sodium intake, total fluid intake, energy intake, urine volume, and urinary sodium excretion were recorded. Total body water was measured by H218O dilution on days 1, 7, and 14, and extracellular fluid volume by sodium bromide dilution on days 1 and 14.
RESULTS—Twenty four infants received early, and 22 delayed, sodium supplementation. There were no significant differences between the groups in body water compartments on day 1. In the delayed group, but not the early group, there was a significant loss of total body water during the first week (delayed −44 ml/kg, p=0.048; early 6 ml/kg, p=0.970). By day 14 the delayed, but not the early group, also had a significant reduction in extracellular fluid volume (delayed −53 ml/kg, p=0.01; early −37 ml/kg, p=0.2). These changes resulted in a significant alteration in body composition at the end of the first week (total body weight: delayed 791 ml/kg; early 849 ml/kg, p=0.013). By day 14 there were once again no significant differences in body composition between the two groups.
CONCLUSIONS—Body composition after preterm birth is influenced by the timing of introduction of routine sodium supplements. Early sodium supplementation can delay the physiological loss of body water that is part of normal postnatal adaptation. This is likely to be of particular relevance to babies with respiratory distress syndrome. A tailored approach to clinical management, delaying the introduction of routine sodium supplements until there has been postnatal loss of body water, is

    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.

    The literature suggests that one of the key determinants of success at rugby union international competitions is the anthropometric profile of players. The Irish Rugby Football Union (IRFU) long-term player development (LTPD) model is a framework designed to guide the development of the tactical, physical, and psychological domains of sporting participation. In Ireland, the Train-to-Train stage of the IRFU model is a critical stage, whereby the next developmental progression would include the transition of players into professional academies. To date, no previously published studies have examined the anthropometric profile of Irish Schools' rugby union players at the Train-to-Train stage of the IRFU model. The anthropometric profile of 136 male adolescent rugby union players at the Train-to-Train stage of the IRFU model was assessed using total-body dual-energy x-ray absorptiometry. Significant differences in height, body mass, body fat percentage, fat mass, lean mass, and fat-free mass were observed between players assigned to the forward and back units, and for specific position categorizations within each unit. Direct logistic regression revealed that body mass was a statistically significant (p < 0.01) predictor of unit position classification, with an odds ratio of 2.35, indicating that the players with a higher body mass were twice as likely to be classified as forwards. The results of this study indicate that at the Train-to-Train stage of the IRFU model, forward and back units have distinctly different anthropometric profiles. Furthermore, anthropometric differentiation also exists within specific position categorizations within each of these playing units. Thus, anthropometric profiling should be carried out on a systematic and periodic basis, because this will allow for the evaluation of the effectiveness of the implementation strategies of the IRFU model on a national basis.

    2010-12-01

    We tested the hypothesis that the previously reported association between a higher body mass index (BMI) and poorer cognition in later adulthood is an artifact of confounding by previous cognitive ability and socioeconomic status. Participants were 1,079 adults aged about 70 years in the Lothian Birth Cohort 1936 Study, on whom there are IQ data from age 11. Cognitive outcome measures included: IQ at age 70 using the same test that was administered at age 11; composite measures of general cognitive ability (g factor), speed of information processing, and memory; and two tests of verbal ability. People classified as overweight or obese in later adulthood had significantly lower scores on tests of childhood IQ, age 70 IQ, g factor, and verbal ability. There was no significant association with processing speed or memory performance. After adjusting for childhood IQ and social class in general linear models, associations with age 70 IQ and g factor were nonsignificant or attenuated. However, throughout the models, there was a persistent (inverse) relationship between BMI and performance on the National Adult Reading Test (NART) and Wechsler Test of Adult Reading (WTAR), which remained significant after full adjustment for all sociodemographic and health covariates (for the NART, p = .025; for the WTAR, p = .011). The findings suggest that the previously reported BMI-cognition associations in later adulthood could be largely accounted for by prior ability and socioeconomic status, and by the possible influence of these factors on the adoption of health behaviors in adulthood.

    Rapid growth during infancy is associated with increased risk of overweight and obesity and differences in weight gain are at least partly explained by means of infant feeding. The aim was to assess the associations between infant feeding practice in early infancy and body mass index (BMI) at 6 years of age. Icelandic infants (n = 154) were prospectively followed from birth to 12 months and again at age 6 years. Birth weight and length were gathered from maternity wards, and healthcare centers provided the measurements made during infancy up to 18 months of age. Information on breastfeeding practices was documented 0-12 months and a 24-h dietary record was collected at 5 months. Changes in infant weight gain were calculated from birth to 18 months. Linear regression analyses were performed to examine associations between infant feeding practice at 5 months and body mass index (BMI) at 6 years. Infants who were formula-fed at 5 months of age grew faster, particularly between 2 and 6 months, compared to exclusively breastfed infants. At age 6 years, BMI was on average 1.1 kg/m2 (95% CI 0.2, 2.0) higher among infants who were formula fed and also receiving solid foods at 5 months of age compared to those exclusively breastfed. In a high-income country such as Iceland, early introduction of solid foods seems to further increase the risk of high childhood BMI among formula fed infants compared with exclusively breastfed infants, although further studies with greater power are needed.

    Abstract Objective This study aims to assess middle-aged women’s needs when making body weight management decisions and to evaluate a knowledge translation tool for addressing their needs. Methods A mixed-methods study used an interview-guided theory-based survey of professional women aged 40 to 65 years. The tool summarized evidence to address their needs and enabled women to monitor actions taken. Acceptability and usability were reported descriptively. Results Sixty female participants had a mean body mass index of 28.0 kg/m2 (range, 17.0-44.9 kg/m2), and half were premenopausal. Common options for losing (82%) or maintaining (18%) weight included increasing physical activity (60%), eating healthier (57%), and getting support (40%). Decision-making involved getting information on options (52%), soliciting others’ decisions/advice (20%), and being self-motivated (20%). Preferred information sources included written information (97%), counseling (90%), and social networking websites (43%). Five professionals (dietitian, personal trainer, occupational therapist, and two physicians) had similar responses. Of 53 women sent the tool, 27 provided acceptability feedback. They rated it as good to excellent for information on menopause (96%), body weight changes (85%), and managing body weight (85%). Most would tell others about it (81%). After 4 weeks of use, 25 women reported that the wording made sense (96%) and that the tool had clear instructions (92%) and was easy to use across time (88%). The amount of information was rated as just right (64%), but the tool had limited space for responding (72%). Conclusions When making decisions about body weight management, women’s needs were “getting information” and “getting support.” The knowledge translation tool was acceptable and usable, but further evaluation is required.

  14. From GED to College: Age Trajectories of Nontraditional Educational Paths

    PubMed Central

    Maralani, Vida

    2015-01-01

    Age patterns of secondary certification and college entry differ in complex and surprising ways for traditional graduates and GED recipients. Although GED recipients are less likely to enter college in their late teens, they catch up to traditional graduates in their 20s. Results show that adjusting for differences in the age trajectories of school continuation accounts for a substantial portion of the differences observed between the two groups. Important differences remain, however, in the type of college attended and the likelihood of college entry before age 21. Nonetheless, more GED recipients enroll in college than previous studies have suggested, and this interest in college identifies a useful place for policy to intervene to encourage school continuation for this group.

    2014-07-01

    This study aims to non-invasively extract the vibrations of the carotid wall and evaluate the changes in the carotid artery wall caused by age and obesity. Such evaluation can increase the possibility of detecting wall stiffness and atherosclerosis in its early stage. In this study, a novel method that uses a phase-tracking method based on the continuous wavelet transform calculates the carotid wall motion from the ultrasound radio frequency signals. To extract the high-frequency components of the wall motion, wall vibration, the empirical mode decomposition was then used. The posterior wall (intima-media) motion and vibration were extracted for 54 healthy volunteers (mean age: 33.87 ± 14.73 years), including 13 overweight subjects (body mass index > 25) and 14 female participants using their radio frequency signals. The results showed that the dominant frequency of the wall vibration correlates with age (r = -0.5887, p < 0.001) and body mass index (r = -0.4838, p < 0.001). The quantitative analysis further demonstrated that the dominant frequency of the vibration in the radial direction of the carotid wall decreases by age and is lower in overweight subjects. Besides, the peak-to-peak amplitude of the wall vibration showed significant correlations with age (r = -0.5456, p < 0.001) and body mass index (r = -0.5821, p < 0.001). The peak-to-peak amplitude also decreases by age and is lower in overweight subjects. However, there were no significant correlations between these features of the wall vibrations and systolic/diastolic blood pressure and sex. Our proposed measures were certified using the calculated arterial stiffness indices. The average power spectrum of the elderly subjects'wall motion in the frequency range of the wall vibration (>100 Hz) is decreased more in comparison with the young subjects. Our results revealed that the proposed method may be useful for detecting the stiffness and distortion in the carotid wall that occur prior to wall thickening

    2015-02-01

    Knowledge of the reproductive biology of game species is vital for sustainable management. In moose (Alces alces), research in reproductive characteristics has focused on the female, whereas there are few studies in male moose. The aim of the present study was to investigate sperm morphology and chromatin integrity (SCSA), and their relationships with testicular and epididymal features, as well as temporal aspects with respect to the hunting season. In total, 143 male moose aged 1.5-11.5 years were sampled from 2008 to 2011. The proportion of normal spermatozoa (PNS) ranged from 1.5% to 82.0%, with a mean of 51%, and the %DFI (DNA fragmentation index) ranged from 2.5% to 36.7% (mean 9.5). PNS decreased temporally, and was positively associated with carcass and testes weight. Body weight and testes weight had positive effect on PNS regardless of age. No effect of any explanatory variables was observed on the DFI. The testis/body weight ratio of moose (0.033%) is among the lowest reported among mammals, indicating a less polygynous mating system than in roe deer and red deer. For reproduction success in moose, a high body weight in males is favorable, as is a balanced sex ratio. Thus, males should not be harvested prior to the time when the majority of females have passed their first oestrus of the season.

  6. Is older colder or colder older? The association of age with body temperature in 18,630 individuals.

    Waalen, Jill; Buxbaum, Joel N

    2011-05-01

    In animal studies, caloric restriction resulting in increased longevity is associated with a reduction in body temperature, which is strain specific and likely under genetic control. Small studies in humans have suggested that temperatures may be lower among elderly populations, usually attributed to loss of thermoregulation. We analyzed cross-sectional data from 18,630 white adults aged 20-98 years (mean 58.3 years) who underwent oral temperature measurement as part of a standardized health appraisal at a large U.S. health maintenance organization. Overall, women had higher mean temperatures (97.5 ± 1.2°F) than men (97.2 ± 1.1°F; p < .0001). Mean temperature decreased with age, with a difference of 0.3°F between oldest and youngest groups after controlling for sex, body mass index, and white blood cell count. The results are consistent with low body temperature as a biomarker for longevity. Prospective studies are needed to confirm whether this represents a survival advantage associated with lifetime low steady state temperature.

    2014-01-01

    We report current findings when considering video recordings of facial expressions and body movements to provide affective personalized support in an educational context from an enriched multimodal emotion detection approach. In particular, we describe an annotation methodology to tag facial expression and body movements that conform to changes in the affective states of learners while dealing with cognitive tasks in a learning process. The ultimate goal is to combine these annotations with additional affective information collected during experimental learning sessions from different sources such as qualitative, self-reported, physiological, and behavioral information. These data altogether are to train data mining algorithms that serve to automatically identify changes in the learners' affective states when dealing with cognitive tasks which help to provide emotional personalized support.

    2014-06-15

    Purpose: Phantom development in medical physics plays an important role in radiation dose assessment and image quality evaluation, and this is especially true in the pediatric patient population. The purpose of this investigation was to establish the relationship between patient age and patient size, focusing on the abdomen-pelvis and head effective diameters, for patients ranging in age from newborn to 18 years. Methods: A dose reporting tool for computed tomography systems was installed at our institution to achieve compliance with state law commencing on July 1, 2012. The software records a number of patient-specific data, and also reports CT dose metrics (CTDIvol and DLP) into the patients interpretive report. The database generated by the software was mined to determine patient effective diameter as a function of age for pediatric patients aged 0–18 years. CT protocols including abdomen-pelvis and routine head were evaluated, and specific to this study the patients age, gender and equivalent diameter were recorded. Results: Six age ranges were evaluated: A(0–3), B(4–6), C(7–9), D(10–12),E(13–15),F(16–18). For the torso in these groups based upon 694 patients, median effective diameters were 147, 167, 184, 214, 231, 246 mm, respectively. For the head (N=1833), median diameters were 143, 157, 162, 168, 174, and 174, respectively. Conclusion: A solid understanding of the approximate dimensions of pediatric patients as a function of age is useful in the development of age-based imaging protocols and dose assessments. CT dose-reporting tools generate a great deal of data with respect to body dimensions automatically. In this study, median equivalent diameters for the abdomen-pelvis and head of pediatric patients were evaluated. These data may prove useful in the development of both mathematical and physical phantoms for dosimetry and image quality assessment.

  9. Trends in the age at reproductive transitions in the developing world: The role of education.

    Bongaarts, John; Mensch, Barbara S; Blanc, Ann K

    2017-04-11

    Girls' school participation has expanded considerably in the developing world over the last few decades, a phenomenon expected to have substantial consequences for reproductive behaviour. Using Demographic and Health Survey data from 43 countries, this paper examines trends and differentials in the mean ages at three critical life-cycle events for young women: first sexual intercourse, first marriage, and first birth. We measure the extent to which trends in the timing of these events are driven either by the changing educational composition of populations or by changes in behaviour within education groups. Mean ages have risen over time in all regions for all three events, except age at first sex in Latin America and the Caribbean. Results from a decomposition exercise indicate that increases in educational attainment, rather than trends within education groups, are primarily responsible for the overall trends. Possible explanations for these findings are discussed.

    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.

    Thirty-six percent of American Wagyu bulls do not meet the current minimum standards set by the Society of Theriogenology for the breeding soundness exam. In contrast, only 15% of bulls of domestic breeds do not meet the minimum standards. Scrotal circumference measurements of Wagyu are smaller than those of other breeds. The objective of this research was to describe scrotal circumference of Wagyu bulls as it relates to age and BW. The data set consisted of 190 Wagyu bulls housed at two locations. One hundred forty-one bulls constituted the first set of data (location 1); scrotal circumference was measured one to six times per bull aged between 13 and 70 mo. Ninety-four of the bulls underwent semen evaluation for motility and morphology. Forty-nine bulls constituted the data set for which scrotal circumference and BW was measured one to nine times per bull between 5 and 21 mo of age (location 2). Mean scrotal circumference of bulls within each age group was as follows: 12 to 14 mo, 29.8 0.2 cm (mean +/- SE); 15 to 17 mo, 31.8 +/- 0.2 cm; 18 to 20 mo, 32.9 +/- 0.3 cm; 21 to 24 mo, 31.8 +/- 0.5 cm; and > 24 mo, 35.5 +/- 0.2 cm. Both age and BW were highly correlated to scrotal circumference (r = 0.81 and 0.82, respectively). Within each age group, there were a percentage of bulls that did not meet the minimum standard for scrotal circumference set by the Society of Theriogenology. The percentages were as follows: 12 to 14 mo, 46%; 15 to 17 mo, 25%; 18 to 20 mo, 33%; 21 to 24 mo, 42%; and > 24 mo, 32%. Morphology and motility were > 50% each in 91% of the bulls between ages 12 and 20 mo at location 1. Based on these data, it is recommended that Wagyu bulls be evaluated with the breed-specific minimum standards for scrotal circumference of 26 cm from 12 to 14 mo, 29 cm from 15 to 17 mo, and 30 cm from 18 to 20 mo of age.

    Although the relationship between education and cognitive status is well-known, evidence regarding whether education moderates the trajectory of cognitive change in late life is conflicting. Early studies suggested that higher levels of education attenuate cognitive decline. More recent studies using improved longitudinal methods have not found that education moderates decline. Fewer studies have explored whether education exerts different effects on longitudinal changes within different cognitive domains. In the present study, we analyzed data from 1014 participants in the Victoria Longitudinal Study to examine the effects of education on composite scores reflecting verbal processing speed, working memory, verbal fluency, and verbal episodic memory. Using linear growth models adjusted for age at enrollment (range, 54-95 years) and gender, we found that years of education (range, 6-20 years) was strongly related to cognitive level in all domains, particularly verbal fluency. However, education was not related to rates of change over time for any cognitive domain. Results were similar in individuals older or younger than 70 at baseline, and when education was dichotomized to reflect high or low attainment. In this large longitudinal cohort, education was related to cognitive performance but unrelated to cognitive decline, supporting the hypothesis of passive cognitive reserve with aging.

    The scope of this study was to evaluate the effectiveness of two methods of educational nutritional intervention together with women who practice regular physical activities by fostering the adoption of healthy eating habits. The study population consisted of 52 women aged between 19 and 59 who frequented the Academia da Cidade Program in Aracaju in the State of Sergipe. The study was a randomized comparison of two intervention groups and was of the pre-test/post-test variety. The educational activities were based on two protocols - one less intensive (P1 Group) and one more intensive (P2 Group) - over a period of two months. The variables analyzed were nutritional knowledge, anthropometric measurements and changes in eating habits. The changes identified were improvement in eating habits and reduction in weight and Body Mass Index for the P2 group. The modifications identified referred mainly to increased consumption of fruit and vegetables, reduction of fat in cooking, reduction in the volume of food eaten per meal and increased meal frequency. In relation to nutritional knowledge, only 2 of the 12 questions showed significant changes. The most intensive method proved effective in changing dietary habits leading to weight loss.

    Objective: To assess the associations between body mass index (BMI), waist circumference (WC), and cardiometabolic risk factors in young and middle-aged Chinese women. Methods: A total of 3011 women (1938 young women, 1073 middle-aged women), who visited our health care center for a related health checkup, were eligible for study. BMI and WC were measured. The subjects were divided into normal and overweight/obesity groups based on BMI, and normal and abdominal obesity groups based on WC. Cardiometabolic variables included triglyceride (TG), high density lipoprotein cholesterol (HDL-C), fasting blood glucose (FBG), homeostasis model assessment of insulin resistance (HOMA-IR), and blood pressure (BP). Results: The prevalence of overweight/obesity was significantly higher in middle-aged women (32.4%) than in young women (12.0%). The prevalence of abdominal obesity was also higher in middle-aged women (60.3%) than in young women (36.2%). There were significant differences in the comparison of all related cardiometabolic variables between different BMI (or WC) categories in young and middle-aged women groups, respectively. After adjustment for age, partial correlation analysis indicated that both BMI and WC were correlated significantly with all related cardiometabolic variables. After adjustment for age and WC, although the correlation coefficient r′ was attenuated, BMI was still correlated significantly with all related cardiometabolic variables in young and middle-aged women. After adjustment for age and BMI, partial correlation analysis showed that WC was correlated significantly with TG, FBG, HOMA-IR, and HDL-C in young women and significantly with TG, HOMA-IR, and HDL-C in middle-aged women. Conclusions: The prevalence of overweight/obesity and abdominal obesity was high in Chinese young and middle-aged women. BMI was a better predictor of cardiovascular disease and diabetes than WC in young and middle-aged women, and moreover, measurement of both WC and BMI

    Primary human aging may be associated with augmented Rho kinase (ROCK)-mediated contraction of vascular smooth muscle and ROCK-mediated inhibition of nitric oxide synthase (NOS). We hypothesized that the contribution of ROCK to reflex vasoconstriction (VC) is greater in aged skin. Cutaneous VC was elicited by 1) whole body cooling [mean skin temperature (Tsk) = 30.5°C] and 2) local norepinephrine (NE) infusion (1 × 10−6 M). Four microdialysis fibers were placed in the forearm skin of eight young (Y) and eight older (O) subjects for infusion of 1) Ringer solution (control), 2) 3 mM fasudil (ROCK inhibition), 3) 20 mM NG-nitro-l-arginine methyl ester (NOS inhibition), and 4) both ROCK + NOS inhibitors. Red cell flux was measured by laser-Doppler flowmetry over each site. Cutaneous vascular conductance (CVC) was calculated as flux/mean arterial pressure and normalized to baseline CVC (%ΔCVCbaseline). VC was reduced at the control site in O during cooling (Y, −34 ± 3; and O, −18 ± 3%ΔCVCbaseline; P < 0.001) and NE infusion (Y, −53 ± 4, and O, −41 ± 9%ΔCVCbaseline; P = 0.006). Fasudil attenuated VC in both age groups during mild cooling; however, this reduction remained only in O but not in Y skin during moderate cooling (Y, −30 ± 5; and O, −7 ± 1%ΔCVCbaseline; P = 0.016) and was not altered by NOS inhibition. Fasudil blunted NE-mediated VC in both age groups (Y, −23 ± 4; and O, −7 ± 3%ΔCVCbaseline; P < 0.01). Cumulatively, these data indicate that reflex VC is more reliant on ROCK in aged skin such that approximately half of the total VC response to whole body cooling is ROCK dependent. PMID:19717729

    Changes in the neighborhood environment may explain part of the rapid increase in childhood overweight and obesity during the last decades. To date few theory-driven rather than data-driven studies have explored longitudinal associations between multiple neighborhood characteristics and child body weight development. We aimed to assess the relationship between physical, social and perceived safety related characteristics of the neighborhood and Body Mass Index (BMI) development in children during early school age, using a longitudinal design. We included an examination of moderating and confounding factors based on a conceptual model adapted from the EnRG framework (Environmental Research framework for weight Gain prevention) and empirical research. Analyses included 1887 children from the KOALA Birth Cohort Study followed from baseline age 4-5 years until 8-9 years. For children age 4-5 years, parents completed a questionnaire measuring characteristics of the neighborhood. Reliability and factor analyses were used to identify constructs for neighborhood characteristics. Linear regression analysis was performed to assess the relationship between neighborhood constructs and BMI z-scores cross-sectionally at age 4-5 years and longitudinally using Generalized Estimating Equations with BMI z-scores over 5 repeated measurements until age 8-9 years. Fourteen constructs were identified and grouped in three domains including perceived physical, social, or safety related characteristics of the neighborhood. Cross-sectionally, a lower BMI z-score was associated with higher perceived physical attractiveness of the neighborhood environment (standardized regression coefficient (β) -0.078, 95% CI -0.123 to -0.034) and a higher level of social capital (β -0.142, -0.264 to -0.019). Longitudinally, similar associations were observed with potentially even stronger regression coefficients. This study suggests that BMI in children is mainly related to the modifiable physical

    Depression is an important health problem in children and the onset of depression is occurring at a younger age than previously suggested. The associations of being overweight and low socioeconomic status in childhood depression have been well documented; nevertheless few studies have addressed the combined effects of socioeconomic status and body weight, with depression in school-age children. We intended to examine if the relationship between socioeconomic status and childhood depression could be modified by abnormal body weight. A cross-sectional study was performed with a total of 559 subjects from 29 elementary schools in Taiwan. A depression scale was used to determine the depression status. Children receiving governmental monetary assistance for after-school class were categorized as being in the lower socioeconomic group. Data for depression-related demographic characteristics, family and school variables were collected. Children in the lower socioeconomic status group have a higher prevalence of depression (23.5%) than those in higher socioeconomic status groups(16.4%). Being overweight demonstrates the opposite effect on depression risk in the different socioeconomic groups. In lower socioeconomic families, the risk of depression in overweight children is three times higher than that for normal weight children; whereas in higher socioeconomic families, overweight children have a lower risk for depression than normal weight children. We concluded that a qualitative interactive effect existed between being overweight and socioeconomic status with childhood depression. More attention should be paid to overweight children from lower socioeconomic status families to prevent depression in school-age children.

    Despite the large body of knowledge on adults suggesting that 2 basic types of mental spatial transformation--namely, object-based and egocentric perspective transformations--are dissociable and specialized for different situations, there is much less research investigating the developmental aspects of such spatial transformation systems. Here, an "own body transformation" paradigm and a letter transformation task were employed in a group of children ranging from 7 to 11 years of age to respectively investigate the development of egocentric perspective transformations and object-related transformations. A group of 30 young adults was also administered the 2 experimental tasks. Moreover, the Temperament and Character Inventory (Cloninger, Przybeck, Svrakic, & Wetzel, 1994) was also administered to children and adults with the goal of testing for possible influences of personality traits on imagined perspective transformation abilities. We found that egocentric perspective transformations develop later than object-based transformations--namely, from 8 rather than 7 years of age. We also found that high scores on temperament and character scales reflecting the acceptance of others (i.e., cooperativeness) were positively related to the ability to engage in imagined perspective transformations, especially when such ability first appears (i.e., at 8 years of age). These findings were held to support the view that the 2 mental spatial transformation systems are separated in that they follow 2 different developmental trajectories and are differentially influenced by personality traits in children.

    This study aimed to examine the relationship between the fat-free mass (FFM) and fat mass (FM) and between the fat-free mass index (FFMI) and fat mass index (FMI) in Chinese children using the Hattori chart and to compare the changing pattern with Korean counterparts. In this study, 1541 (764 girls) children and adolescents aged 5-19 yr were recruited from southern China. The subjects' body composition was measured using dual-energy X-ray absorptiometry. The relationship between FFM and FM and between FFMI and FMI were delineated using the Hattori chart. Between 5 and 12 yr, a concurrent increase in FFM and FM and in FFMI and FMI was found in both sexes. After 12 yr, the age-related changing patterns are generally characterized by a sharp increase in FM, with a relatively small increase in FFM for girls, and a sharp increase in FFM, with a relatively little fluctuation in FM for boys. The increase in weight and BMI with age for this stage is largely due to the increase in FFM and FFMI in boys and in both the FFM and FM and FFMI and FMI components in girls. Sex differences in the patterns of body composition were found in Chinese children and adolescents.

Study Design Cross-sectional cohort study Setting The Health, Aging, and Body Composition (Health ABC) study; A community-based cohort study of older adults from Pittsburgh, PA and Memphis TN. Participants 2,049 well-functioning adults (mean age: 77.5 years; 37% black) Measurements Pure-tone audiometry and history of clinical CVD were obtained at the 4th annual follow-up visit. Pure-tone averages in decibels reflecting low frequencies (250, 500, and 1000 Hz) middle frequencies (500, 1000, and 2000 Hz) and high frequencies (2000, 4000, and 8000Hz) were calculated for each ear. CVD risk factors, aortic pulse-wave velocity, and ankle-arm index were obtained at the study baseline. Results In gender-stratified models, after adjustment for age, race, study site and occupational noise exposure, risk factors associated with poorer hearing sensitivity among men included higher triglyceride levels, higher resting heart rate and history of smoking. Among women, poorer hearing sensitivity was associated with higher BMI, higher resting heart rate, faster pulse-wave velocity, and low ankle-arm index. Conclusion Modifiable risk factors for CVD may play a role in the development of age-related hearing loss. PMID:21649629

    Impairment of one or more parameters of circadian rhythms (CR) of body temperature (BT) and locomotor activity (LMA) are considered among the hallmarks of mammalian aging. These alterations are frequently used as markers for imminent death in laboratory mice. However, there are still contradictory data for particular strains and it is also uncertain which changes might predict senescence changes later in life, including the force of mortality. In the present paper we use telemetry to study LMA and CR of BT during aging of BALB/c mice. At our knowledge this is the first time that CR of BT and LMA are investigated in this strain in a range of age covering the whole lifespan, from young adult up to very old age. CR of BT was analyzed with a cosine model using a cross sectional approach and follow-up measurements. The results show that BT, LMA, amplitude, goodness-of-fit (GoF) to circadian cycle of temperature decrease with different shapes during chronological age. Moreover, we found that the % change of amplitude and BT in early life (5-19 months) can predict the remaining lifespan of the mice. Later in life (22-32 months), best predictors are single measurements of LMA and GoF. The results of this study also offer potential measures to rapidly identifying freely unrestrained mice with the worst longitudinal outcome and against which existing or novel biomarkers and treatments may be assessed.

    "This study uses data from the June 1992 Current Population Survey to examine the effect of educational attainment on age at first marriage among Black and White women in the United States. The results both support and modify claims stemming from previous research. There is evidence for the contention that educational attainment delays age at first marriage for Black and White women. The greater impact of educational attainment on delaying marriage for White women in confirmed. An important discovery stems from using degree attained rather than years of education and our distinguishing four levels of education beyond high school. At less than a bachelor's degree, Black women marry later than White women, but among those with a bachelor's degree or higher, Black women who marry do so earlier than White women."

    High dietary carbohydrate is suggested to promote development of diabetes mellitus in cats. Glucose tolerance, insulin sensitivity, and insulin secretion were assessed in young [0.8-2.3 (median = 1.1) years, n = 13] and mature [4.0-7.0 (median 5.8) years, n = 12] sexually intact females of a large (n ≅ 700) feline colony in which only dry-type diets (35% metabolizable energy as carbohydrate) were fed from weaning. Insulin sensitivity was assessed from the 'late-phase' (60-120 min) plasma insulin response of intravenous glucose tolerance tests (IVGTTs) and from fractional change in glycaemia from baseline 15 min after an insulin bolus (0.1 U/kg, i.v.). Insulin secretion was assessed from the 'early-phase' (0-15 min) plasma insulin response of IVGTTs. Compared to the young cats, the mature cats had greater body weights [2.3-3.8 (median = 2.9) vs. 3.0-6.3 (median = 4.0) kg, p < 0.01], greater late-phase insulin responses (p < 0.05), lower insulin-induced glycaemic changes (p = 0.06), lower early-phase insulin responses (p < 0.05), and non-significantly different rates of glucose disposal. The late-phase insulin response was correlated with body weight and age (p < 0.05). When group assignments were balanced for body weight, the age-group differences and correlations became non-significant. The findings indicate that body weight gain is more likely than dry-type diets to induce the pre-diabetic conditions of insulin resistance and secretion dysfunction.

    The original validation study for the Montreal Cognitive Assessment (MoCA) suggests a cutoff score of 26; however, this may be too stringent for older adults, particularly for those with less education. Given the rapidly increasing number of older adults and associated risk of dementia, this study aims to provide appropriate age- and education-adjusted norms for the MoCA. Data from 205 participants in an ongoing longevity study were used to derive normative data. Individuals were grouped based on age (70-79, 80-89, 90-99) and education level (≤12 Years, 13-15, ≥16 Years). There were significant differences between age and education groups with younger and more educated participants outperforming their counterparts. Forty-six percent of our sample scored below the suggested cutoff of 26. These normative data may provide a more accurate representation of MoCA performance in older adults for specific age and education stratifications.

    Social rank in cervids and other mammals is not entirely predicted by body weight, but in most cases influences access to food directly. Milk provisioning depends on maternal weight and on daily food intake. Usually, body weight, body condition, age and social rank are inter-correlated making it very difficult to discern the relative importance of each variable to milk production. This study used path analysis to assess direct versus indirect effects of these variables on milk production of 62 Iberian red deer hinds (Cervus elaphus hispanicus). Once the known direct effects of body weight and body condition were set as fixed, hind age and social rank did not affect milk production directly. In contrast, they exerted an indirect influence through the correlation both with hind body weight and body condition. Body weight exerted an effect on milk production nearly twice as great as that of body condition. This study shows, for the first time in a wild mammal, the relative importance of social rank, body weight, body condition and age in affecting milk production ability.

    The relevance of the insulin gene (INS) variable number tandem repeat (VNTR) polymorphism to indexes of body size and adult obesity is inconclusive. Given the equivocal reports on the association between the VNTR class genotype at the insulin gene locus and indexes of body size and obesity, we assessed these associations in a series of cohort studies based on 7,999 middle-aged men and women. We found no convincing evidence that INS VNTR class genotype was associated with indexes of body size and adult obesity. These data suggest that INS VNTR class is not an important determinant of size and body weight regulation in middle-aged men and women.

  15. Combining Hf-W Ages, Cooling Rates, and Thermal Models to Estimate the Accretion Time of Iron Meteorite Parent Bodies

    The 182Hf-182W short-lived chronometer has been widely used to date metal-silicate differentiation processes in the early Solar System. However the presence of cosmogenic effects from exposure to GCR can potentially hamper the use of this system for chronology purposes (e.g. [1,2]). These effects must be corrected for in order to calculate metal-silicate differentiation ages. In this study, high-precision W isotope measurements are presented for 32 iron meteorites from 8 magmatic and 2 non-magmatic groups. Exposure ages and pre- atmospheric size estimates are available for most of these samples [3]. Our precision is better than or comparable to the currently most precise literature data and our results agree with previous work [4]. All magmatic irons have ɛ182W equal within error to or more negative than the Solar System initial derived from a CAI isochron [5]. Iron meteorites from the same magmatic groups show variations in ɛ182W. These are most easily explained by exposure to cosmic rays in space. A correction method was developed to estimate pre-exposure ɛ182W for individual iron meteorite groups. Metal-silicate differentiation in most iron meteorite parent bodies must have occurred within 2 Myr of formation of refractory inclusions. For the first time, we combine 182Hf-182W ages with parent body sizes inferred from metallographic cooling rates in a thermal model to constrain the accretion time of iron meteorite parent bodies. The estimated accretion ages are within 1.5 Myr for most magmatic groups, and could be as early as 0.2 Myr after CAI formation. This is consistent with the study of Bottke et al. [6] who argued that iron meteorite parent bodies could represent an early generation of planetesimals formed in the inner region of the Solar System. [1] Masarik J. (1997) EPSL 152, 181-185.

    Objective: To examine the correlation between body fat percentage (BFP) and general obesity indexes, including body mass index (BMI), waist circumference (WC) and waist to hip ratio (WHR) and calculate the corresponding BFP cutoff values in the middle aged and old people in Guangzhou. The corresponding cut-point of optimal body fat percentage for Guangzhou older population. Methods: Based on the Guangzhou Biobank Cohort Study (GBCS), 3 490 relatively healthy Guangzhou residents aged ≥50 years were selected and were randomly divided into 2 groups. The equations between BFP and BMI, WC, WHR were set up with Curve fitting analysis in one group. The multiple regression analysis was undertaken to establish predictive equations between BFP and BMI, WC, WHR with stepwise model for adding gender, age, physical activity, drinking and smoking. Then, the optimal cut-points of BFP corresponding to BMI, WC and WHR to reflect the degree of obesity were calculated. The equations were then validated with another group. Results: BFP increased with the increase of WHR, WC and BMI. BMI was a better predictor of body fat percentage than WC and WHR. The final regression equation was BFP=(-23.47 -8.87×sex) +2.94× (BMI) - 0.024 × (BMI)(2),the coefficient of determination was 0.805. Based on the equation, the BFP corresponding to overweight/obesity (24 kg/m(2)≤BMI<28 kg/m(2)) were 24.3% ≤BFP<31.1% in men and 33.2%≤BFP<40.0% in women, respectively. BMI had a better consistency with BFP in identify obesity compared with WC and WHR, obtained the area of ROC 0.909 in men and 0.919 in women respectively. The sensitivity and specificity were 70.3% and 85.5% in men; and 75.2% and 93.0% in women respectively. Conclusion: BFP has a better correlation with BMI. The study results indicated that BFP for middle aged and old males and females in Guangzhou corresponding to overweight/obesity (BMI≥24 kg/m(2)) were <24.0% and <33.0% respectively.

    The aims of this study were to (1) identify sperm subpopulations with specific motion characteristics in fresh Andalusian donkey ejaculates; (2) evaluate the effects of individual donkey and ejaculates within the same donkey on the distribution of the subpopulations found; and (3) explore the relationship between the age and the body weight of donkey donors, the sperm quality parameters, and the sperm subpopulations structure. Sixty ejaculates from 12 Andalusian donkeys (five ejaculates per donkey), ranging in age from 4 to 15 years, were collected. Immediately after collection, sperm characteristics (volume, sperm concentration, objective sperm motility, and sperm morphology) were assessed. Donkeys were evaluated for body weight. Significant (P < 0.05) correlations were established between the body weight of the donkeys and the pH (r = -0.52), sperm motility (percentage of motile spermatozoa: r = -0.31; percentage of progressive motile spermatozoa: r = -0.34), and total sperm abnormalities (r = 0.38). The correlations of the age with the measures of semen quality were low and not significant (P > 0.05). A multivariate clustering procedure separated 65,342 motile spermatozoa into four subpopulations: subpopulation 1, consisting of slow and nonprogressive spermatozoa (15.4%), subpopulation 2, consisting of moderately slow but progressive spermatozoa (35.9%), subpopulation 3, consisting of highly active but nonprogressive spermatozoa (18.5%), and subpopulation 4, consisting of highly active and progressive spermatozoa (30.2%). The distribution of these subpopulations varied significantly (P < 0.05) according to several parameters such as the individual donkey, the ejaculate of the same donkey, the total motility, and the overall sperm concentration. Our results show the existence of four well-defined motile sperm subpopulations in Andalusian donkey ejaculates, and suggest a high heterogeneity in the ejaculate structure in donkey.

    True integration requires a shift in all levels of medical and allied health education; one that emphasizes team learning, practicing, and evaluating from the beginning of each students' educational experience whether that is as physician, nurse, psychologist, or any other health profession. Integration of healthcare services will not occur until medical education focuses, like the human body, on each system working inter-dependently and cohesively to maintain balance through continual change and adaptation. The human body develops and maintains homeostasis by a process of communication: true integrated care relies on learned interprofessionality and ensures shared responsibility and practice.

    This study investigated the relationship between education and physical activity and the difference between a physiological prediction of age and chronological age (CA). Cortical and subcortical gray matter regional volumes were calculated from 331 healthy adults (range: 19-79 years). Multivariate analyses identified a covariance pattern of brain volumes best predicting CA (R(2) = 47%). Individual expression of this brain pattern served as a physiologic measure of brain age (BA). The difference between CA and BA was predicted by education and self-report measures of physical activity. Education and the daily number of flights of stairs climbed (FOSC) were the only 2 significant predictors of decreased BA. Effect sizes demonstrated that BA decreased by 0.95 years for each year of education and by 0.58 years for 1 additional FOSC daily. Effects of education and FOSC on regional brain volume were largely driven by temporal and subcortical volumes. These results demonstrate that higher levels of education and daily FOSC are related to larger brain volume than predicted by CA which supports the utility of regional gray matter volume as a biomarker of healthy brain aging.

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

  3. Education and Research for the Age of Nanoelectronics

    Nanoelectronics has great potential for further, sustainable growth, and this growth is needed worldwide, because new chips provide the technology foundation for all those products and services that shape our lives. However, the concern is justified that this truth is not the perception of the public in the first decades of the new millennium. How can we work towards a broad, sustained commitment to an innovation ecosystem involving education, research, business, and public policy? Reminding ourselves of the 10x programs invoked in Chap. 2 to describe major milestones in advancing microelectronics towards today's nanoelectronics, we notice that all of them demanded requirements-driven, top-down research with ambitious, often disruptive targets for new products or services. Coming closer to the end of the nanometer focus, the new task of global proportion should be a femto-Joule focus on minimum-energy nanoelectronic systems research.

    The authors know of no published studies that have evaluated the effect of Spanish- versus English-language on category fluency within a sample of United States Latinos only. As part of a pilot study for the institution of a cognitive screening program in a cohort of Latinos, we assessed category fluency (fruits, vegetables, and "other" supermarket items) in a sample of 90 self-identified Latino community residents (aged 52-84, 0-18 years of education). The primary demographic correlates of category fluency were age and education. The decrement in naming of fruits with age was limited to the older old subjects (>age 70). Relatively younger old subjects (aged 61-70) did not differ from middle-aged subjects on category fluency. Gender showed little relationship to category naming. Persons naming in Spanish named significantly fewer 'other supermarket' items, but did not differ from English speakers in the more common fluency categories of fruits and vegetables. This analysis of category fluency in an ethnically homogenous sample with a wide range of formal education provided an evaluation of the effects of chosen language free of possible confounding by cultural differences, and also provided a more complete evaluation of the influence of education on category fluency.

    The study aim was to investigate the association between prenatal exposure to endocrine disrupting chemicals (EDCs) and the body composition of 7 to 9 year old Flemish children. The subjects were 114 Flemish children (50% boys) that took part in the first Flemish Environment and Health Study (2002–2006). Cadmium, PCBs, dioxins, p,p′-DDE and HCB were analysed in cord blood/plasma. When the child reached 7–9 years, height, weight, waist circumference and skinfolds were measured. Significant associations between prenatal exposure to EDCs and indicators of body composition were only found in girls. After adjustment for confounders and covariates, a significant negative association was found in girls between prenatal cadmium exposure and weight, BMI and waist circumference (indicator of abdominal fat) and the sum of four skinfolds (indicator of subcutaneous fat). In contrast, a significant positive association (after adjustment for confounders/covariates) was found between prenatal p,p′-DDE exposure and waist circumference as well as waist/height ratio in girls (indicators of abdominal fat). No significant associations were found for prenatal PCBs, dioxins and HCB exposure after adjustment for confounders/covariates. This study suggests a positive association between prenatal p,p′-DDE exposure and indicators of abdominal fat and a negative association between prenatal cadmium exposure and indicators of both abdominal as well as subcutaneous fat in girls between 7 and 9 years old. - Highlights: • Associations between prenatal contaminant exposure and anthropometrics in children. • Significant association only found in girls. • No significant associations found for prenatal PCBs, dioxins and HCB exposure. • Girls: negative association between cadmium and abdominal and subcutaneous fat. • Girls: positive association between p,p′-DDE and indicators of abdominal fat.

  7. Viewing a person through the body: the relevance of philosophical anthropology to medical education.

    2009-12-01

    Although the revival of medical humanities in the past three decades has emerged primarily in the US and the UK, continental Europe has a strong tradition in espousing the medical humanities, such as by advancing the anthropological movement in medicine and philosophy. In this paper, we argue that philosophical anthropology deserves a separate focus in medical education from medical ethics and philosophy of science. The focus of the paper is on the philosophical aspects of the human body to view a person 'through the body.' First, a short description of the anthropological movement in medicine is discussed, including its central motive 'to introduce the subject into medicine.' Next, the ontological and moral relationship between the person and his or her body is addressed. Drawing examples from anatomy, a so-called hemicorporectomy, organ donation, and aesthetic surgery, the concept of bodily integrity is expounded. These ideas can encourage medical students to discuss their own moral experiences during medical training and should be taught to enhance their philosophical understanding of medicine and health care.

    The Japanese quail is a very valuable animal model for research in a variety of biological disciplines. The purpose of this study was to characterize and interrelate age-dependent testicular parameters with various blood constituents: blood glucose, plasma proteins and packed cell volume that are developing concurrently in the growing bird. Another objective of the study was to identify selective physioanatomical markers for predicting the testicular growth and the onset of sexual maturity. Male Japanese quail hatchlings were raised in temperature controlled brooders for up to 3 weeks of age under a constant light and then shifted to hanging cages in an air conditioned room set at ~73° F under a 14L: 10D lighting system and ad libitum access to feed and water. Starting d8, a group of 8-10 birds of uniform size and weight were selected randomly at 4-day intervals up to d52 of age for the project. The birds were weighed and blood sampled using the brachial vein and Blood Glucose (BGL), Total Plasma Proteins (PP) and Packed Cell Volume (PCV) levels were measured prior to euthanization. The testes were removed and measured for weight, length, width and Volume (VOL). All the testicular measurements were then correlated with age and body weight. The left testes were larger than the right testes and their differences were evident at d36 of age. Testicular measurements also reflected two distinct growth surges at d28, d32 and d36 of age. Combined Testes Weight (CTW) and Combined Testes Volume (CTV) revealed a strong positive correlation with PCV and PP and a negative correlation with Blood Glucose Level (BGL). Accordingly, these measurements could serve as reliable markers of growth rate and sexual maturation in male Japanese quail.

    Obesity and ageing are emerging issues in the management of captive primates, including Chimpanzees, Pan troglodytes. Studies on humans show that obesity and old age can independently increase the risk of inflammatory-associated diseases indicated by elevated levels of pro-inflammatory cells and proteins in the blood of older or obese compared to levels in younger or non-obese individuals. In humans, sex can influence the outcomes of these risks. Health management of these problems in chimpanzee populations requires an understanding of similarities and differences of factors influencing inflammatory disease risks in humans and in chimpanzees. We examined the relationship between age, sex and Body Mass Index (BMI) with hematological biomarkers of inflammatory disease risk established for humans which include the neutrophil to lymphocyte ratio (NLR), and neutrophil, white blood cell (WBC), platelet microparticle and platelet counts. We found that higher values of NLR, neutrophil count and platelet microparticle count were associated with higher BMI values and older age indicating increased inflammation risk in these groups; a similar pattern to humans. There was a strong sex by age interaction on inflammation risk, with older males more at risk than older females. In contrast to human studies, total WBC count was not influenced by BMI, but like humans, WBC and platelet counts were lower in older individuals compared to younger individuals. Our findings are similar to those of humans and suggest that further insight on managing chimpanzees can be gained from extensive studies of ageing and obesity in humans. We suggest that managing BMI should be an integral part of health management in captive chimpanzee populations in order to partially reduce the risk of diseases associated with inflammation. These results also highlight parallels in inflammation risk between humans and chimpanzees and have implications for understanding the evolution of inflammation related

    Life-history strategies vary dramatically between the sexes, which may drive divergence in sex-specific senescence and mortality rates. Telomeres are tandem nucleotide repeats that protect the ends of chromosomes from erosion during cell division. Telomeres have been implicated in senescence and mortality because they tend to shorten with stress, growth and age. We investigated age-specific telomere length in female and male red-sided garter snakes, Thamnophis sirtalis parietalis We hypothesized that age-specific telomere length would differ between males and females given their divergent reproductive strategies. Male garter snakes emerge from hibernation with high levels of corticosterone, which facilitates energy mobilization to fuel mate-searching, courtship and mating behaviours during a two to four week aphagous breeding period at the den site. Conversely, females remain at the dens for only about 4 days and seem to invest more energy in growth and cellular maintenance, as they usually reproduce biennially. As male investment in reproduction involves a yearly bout of physiologically stressful activities, while females prioritize self-maintenance, we predicted male snakes would experience more age-specific telomere loss than females. We investigated this prediction using skeletochronology to determine the ages of individuals and qPCR to determine telomere length in a cross-sectional study. For both sexes, telomere length was positively related to body condition. Telomere length decreased with age in male garter snakes, but remained stable in female snakes. There was no correlation between telomere length and growth in either sex, suggesting that our results are a consequence of divergent selection on life histories of males and females. Different selection on the sexes may be the physiological consequence of the sexual dimorphism and mating system dynamics displayed by this species.

    Hymenopteran eusociality has been proposed to be associated with the activity of the transcription factor CREB (cAMP-response element binding protein). The honeybee (Apis mellifera) is a eusocial insect displaying a pronounced age-dependent division of labor. In honeybee brains, CREB-dependent genes are regulated in an age-dependent manner, indicating that there might be a role for neuronal honeybee CREB (Apis mellifera CREB, or AmCREB) in the bee's division of labor. In this study, we further explore this hypothesis by asking where in the honeybee brain AmCREB-dependent processes might take place and whether they vary with age in these brain regions. CREB is activated following phosphorylation at a conserved serine residue. An increase of phosphorylated CREB is therefore regarded as an indicator of CREB-dependent transcriptional activation. Thus, we here examine the localization of phosphorylated AmCREB (pAmCREB) in the brain and its age-dependent variability. We report prominent pAmCREB staining in a subpopulation of intrinsic neurons of the mushroom bodies. In these neurons, the inner compact cells (IC), pAmCREB is located in the nuclei, axons, and dendrites. In the central bee brain, the IC somata and their dendritic region, we observed an age-dependent increase of pAmCREB. Our results demonstrate the IC to be candidate neurons involved in age-dependent division of labor. We hypothesize that the IC display a high level of CREB-dependent transcription that might be related to neuronal and behavioral plasticity underlying a bee's foraging behavior.

    We have previously shown that individual differences in educational achievement are highly heritable in the early and middle school years in the UK. The objective of the present study was to investigate whether similarly high heritability is found at the end of compulsory education (age 16) for the UK-wide examination, called the General Certificate of Secondary Education (GCSE). In a national twin sample of 11,117 16-year-olds, heritability was substantial for overall GCSE performance for compulsory core subjects (58%) as well as for each of them individually: English (52%), mathematics (55%) and science (58%). In contrast, the overall effects of shared environment, which includes all family and school influences shared by members of twin pairs growing up in the same family and attending the same school, accounts for about 36% of the variance of mean GCSE scores. The significance of these findings is that individual differences in educational achievement at the end of compulsory education are not primarily an index of the quality of teachers or schools: much more of the variance of GCSE scores can be attributed to genetics than to school or family environment. We suggest a model of education that recognizes the important role of genetics. Rather than a passive model of schooling as instruction (instruere, 'to build in'), we propose an active model of education (educare, 'to bring out') in which children create their own educational experiences in part on the basis of their genetic propensities, which supports the trend towards personalized learning.

    This study examined the effect of an early childhood obesity prevention program on changes in Body Mass Index (BMI) z-score and nutrition practices. Eight child care centers were randomly assigned to an intervention or attention control arm. Participants were a multiethnic sample of children aged 2 to 5 years old (N = 307). Intervention centers received healthy menu changes and family-based education focused on increased physical activity and fresh produce intake, decreased intake of simple carbohydrate snacks, and decreased screen time. Control centers received an attention control program. Height, weight, and nutrition data were collected at baseline and at 3, 6, and 12 months. Analysis examined height, weight, and BMI z-score change by intervention condition (at baseline and at 3, 6, and 12 months). Pearson correlation analysis examined relationships among BMI z-scores and home activities and nutrition patterns in the intervention group. Child BMI z-score was significantly negatively correlated with the number of home activities completed at 6-month post intervention among intervention participants. Similarly, intervention children consumed less junk food, ate more fresh fruits and vegetables, drank less juice, and drank more 1% milk compared to children at control sites at 6 months post baseline. Ninety-seven percent of those children who were normal weight at baseline were still normal weight 12 months later. Findings support child care centers as a promising setting to implement childhood obesity prevention programs in this age group.

    Prenatal growth restraint, if followed by postnatal overweight, confers risk for adult disease including diabetes. The mechanisms whereby neonatal nutrition may modulate such risk are poorly understood. We studied the effects of nutrition (breast-feeding [BRF] vs. formula-feeding [FOF]) on weight partitioning and endocrine state (as judged by high-molecular-weight [HMW] adiponectin and IGF-I) of infants born small for gestational age (SGA). Body composition (by absorptiometry), HMW adiponectin, and IGF-I were assessed at birth and 4 months in BRF infants born appropriate for gestational age (AGA; n = 72) and SGA infants receiving BRF (n = 46) or FOF (n = 56), the latter being randomized to receive a standard (FOF1) or protein-rich formula (FOF2). Compared with AGA-BRF infants, the catchup growth of SGA infants was confined to lean mass, independently of nutrition. Compared with AGA-BRF infants, SGA-BRF infants had normal HMW adiponectin and IGF-I levels at 4 months, whereas SGA-FOF infants had elevated levels of HMW adiponectin (particularly SGA-FOF1) and IGF-I (particularly SGA-FOF2). In conclusion, neonatal nutrition seems to influence endocrinology more readily than body composition of SGA infants. Follow-up will disclose whether the endocrine abnormalities in SGA-FOF infants can serve as early markers of an unfavorable metabolic course and whether they may contribute to design early interventions that prevent subsequent disease, including diabetes.

    Antrodia cinnamomea is a precious edible fungus endemic to Taiwan that has long been used as a folk remedy for health promotion and for treating various diseases. In this study, an index of 13 representative metabolites from the ethanol extract of A. cinnamomea fruiting body was established for use in quality evaluation. Most of the index compounds selected, particularly the ergostane-type triterpenoids and polyacetylenes, possess good anti-inflammation activity. A comparison of the metabolite profiles of different ethanol extracts from A. cinnamomea strains showed silmilar metabolites when the strains were grown on the original host wood (Cinnamomum kanehirai) and harvested after the same culture time period (9 months). Furthermore, the amounts of typical ergostane-type triterpenoids in A. cinnamomea increased with culture age. Culture substrates also influenced metabolite synthesis; with the same culture age, A. cinnamomea grown on the original host wood produced a richer array of metabolites than A. cinnamomea cultured on other wood species. We conclude that analysis of a fixed group of compounds including triterpenoids, benzolics, and polyacetylenes constitutes a suitable, reliable system to evaluate the quality of ethanol extract from A. cinnamomea fruiting bodies. The evaluation system established in this study may provide a platform for analysis of the products of A. cinnamomea.

    Previous medical research has shown that children with end-stage renal failure experience delay or underachievement of key markers of transition to adulthood. This article analyses 35 qualitative interviews with end-stage renal failure patients, aged 20-30 years, first diagnosed at 0-19 years of age, to explore how far delayed or underachievement in education and employment is related to their age at onset of end-stage renal failure. This study shows how unpredictable failures of renal replacement therapies, comorbidities and/or side effects of treatment in the early life course often coincided with critical moments for education and employment. Entering school, college, work-related training or employment, and disclosing health status or educational underachievement to an employer, were particularly critical, and those who were ill before puberty became progressively more disadvantaged in terms of successful transition into full-time employment, compared with those first diagnosed after puberty.

    The number of older people in Australia is growing fast, and gerontology has recently become a recognised area of study in tertiary institutions. However, negative attitudes persist among health and welfare professionals, and ways in which gerontology courses can combat the myths associated with aging and the aged are discussed. It is pointed out that people do not grow old in isolation, but in a social context. Education for older people should be seen as a part of social policy, recognising the lifelong right to education. The University of the Third Age (U3A) is a response to the demand for education from older people. The origins of this movement in Europe, and its spread to North America and Australia, are outlined. To meet the needs of older people, courses offered by U3A's have to be multidisciplinary.

  18. Toward Reducing Ageism: PEACE (Positive Education about Aging and Contact Experiences) Model.

    The population of older adults is growing worldwide. Negative ageism (negative attitudes and behavior toward older adults) is a serious international concern that negatively influences not only older adults but also individuals across the age continuum. This article proposes and examines the application of an integrative theoretical model across empirical evidence in the literature on ageism in psychology, medicine, social work, and sociology. The proposed Positive Education about Aging and Contact Experiences (PEACE) model focuses on 2 key contributing factors expected to reduce negative ageism: (a) education about aging including facts on aging along with positive older role models that dispel negative and inaccurate images of older adulthood; and (b) positive contact experiences with older adults that are individualized, provide or promote equal status, are cooperative, involve sharing of personal information, and are sanctioned within the setting. These 2 key contributing factors have the potential to be interconnected and work together to reduce negative stereotypes, aging anxiety, prejudice, and discrimination associated with older adults and aging. This model has implications for policies and programs that can improve the health and well-being of individuals, as well as expand the residential, educational, and career options of individuals across the age continuum.

    There are many studies showing that physical training improves body composition including bone mineral density (BMD) in almost all subjects. However, the frequency-dependent effect of playing golf on body composition is still not clearly comprehended. Moreover, the effect of screen golf in relations with exercise-frequency on body composition and golf performance has not been documented. Forty year old men participated and were classified into 4 groups: Control group (n= 10), BMD1 group (n= 10) played screen golf less than 1 day per a week, BMD2–3 group (n= 10) played screen golf 2–3 days per a week, and BMD5 group (n= 10) played screen golf 5 days per week. Dual-energy X-ray absorptiometry (DXA) was performed on 30 male recreational golfers and 10 sedentary individuals. The data gained through DXA were fat mass, lean mass, regional (head, rib, arm, leg, pelvis, spine and trunk) BMD level, and total BMD level summed by regional scores. The club speeds were measured using the Golfzon Vision machine and the handicap points were measured using a simple questionnaire. The present results suggest that the long-frequency of playing screen golf does not improve bone mineral density, lean mass, and handicap point yet improves fat mass and club speed in the middle-aged men.

    A growing body of literature supports the association between adverse stress experiences and health inequities, including obesity, among African American/Black women. Adverse stress experiences can contribute to poor appetite regulation, increased food intake, emotional eating, binge eating, and sedentary behavior, all of which can contribute to weight gain and obesity. Most research studies concerning the effect of psychological stress on eating behaviors have not examined the unique stress experience, body composition, and eating behaviors of African American/Black women. Even fewer studies have examined these constructs among Black female college students, who have an increased prevalence of overweight and obesity compared to their counterparts. Therefore, the aim of the current study is to examine the associations among emotional eating, perceived stress, contextualized stress, and BMI in African American female college students. All participants identified as African American or Black (N=99). The mean age of the sample was 19.4 years (SD=1.80). A statistically significant eating behavior patterns×perceived stress interaction was evident for body mass index (BMI) (β=0.036, S.E.=.0118, p<.01). In addition, a statistically significant eating behavior patterns×contextualized stress interaction was observed for BMI (β=0.007, S.E.=.0027, p=.015). Findings from this study demonstrate that the stress experience interacts with emotional eating to influence BMI. Based on these findings, culturally relevant interventions that target the unique stress experience and eating behavior patterns of young African American women are warranted.

    Sporadic inclusion-body myositis and hereditary inclusion-body myopathies are progressive muscle diseases leading to severe disability. We briefly summarize their clinical pictures and pathologic diagnostic criteria and discuss the latest advances in illuminating their pathogenic mechanism(s). We emphasize how different etiologies might lead to the strikingly similar pathology and possibly similar pathogenic cascade. On the basis of our research, several processes seem to be important in relation to the still speculative pathogenesis, including (a) increased transcription and accumulation of amyloid-beta precursor protein and accumulation of its proteolytic fragment amyloid-beta; (b) abnormal accumulation of components related to lipid metabolism, for example, cholesterol, accumulation of which is possibly owing to its abnormal trafficking; (c) oxidative stress; (d) accumulations of other Alzheimer's disease-related proteins; and (e) a milieu of muscle cellular aging in which these changes occur. We discuss a potentially very important role of unfolded and/or misfolded proteins as a possible mechanism in the formations of the inclusion bodies and other abnormalities.

    Background Polybrominated diphenyl ethers (PBDEs) are lipophilic flame retardants that bioaccumulate in humans. Child serum PBDE concentrations in California are among the highest worldwide. PBDEs may be associated with obesity by disrupting endocrine systems. Objective In this study, we examined whether pre- and postnatal exposure to the components of pentaBDE mixture was associated with childhood obesity in a population of Latino children participating in a longitudinal birth cohort study in the Salinas Valley, California. Methods We measured PBDEs in serum collected from 224 mothers during pregnancy and their children at 7 years of age, and examined associations with body mass index (BMI) at age 7 years. Results Maternal PBDE serum levels during pregnancy were associated with higher BMI z-scores in boys (BMI z-score βadjusted = 0.26; 95% CI: –0.19, 0.72) but lower scores in girls (BMI z-score βadjusted = –0.41; 95% CI: –0.87, –0.05) at 7 years of age (pinteraction = 0.04). In addition, child’s serum BDE-153 concentration (log10), but not other pentaBDE congeners, demonstrated inverse associations with BMI at age 7 years (BMI z-score βadjusted = –1.15; 95% CI: –1.53, –0.77), but there was no interaction by sex. Conclusions We estimated sex-specific associations with maternal PBDE levels during pregnancy and BMI at 7 years of age, finding positive associations in boys and negative associations in girls. Children’s serum BDE-153 concentrations were inversely associated with BMI at 7 years with no difference by sex. Future studies should examine the longitudinal trends in obesity with PBDE exposure and changes in hormonal environment as children transition through puberty, as well as evaluate the potential for reverse causality.

    Background: Prenatal exposure to endocrine disruptors has been associated with increased risk of childhood obesity. However, epidemiologic studies on polybrominated diphenyl ethers (PBDEs) are limited despite animal studies indicating PBDEs’ potential role as an obesogen. Objectives: We investigated whether maternal concentrations of BDEs 28, 47, 99, 100, 153, and ΣPBDEs during pregnancy were associated with anthropometric measures in children aged 1–8 years. Methods: We examined 318 mother–child pairs in the Health Outcomes and Measures of the Environment (HOME) Study, a birth cohort enrolled from 2003 through 2006 (Cincinnati, OH). Serum PBDEs were measured at 16 ± 3 weeks gestation. We measured child height (1–8 years), weight (1–8 years), body mass index (BMI) (2–8 years), waist circumference (4–8 years), and body fat (8 years). To account for repeated measures, we used linear mixed models and generalized estimating equations to estimate associations between maternal PBDEs and child anthropometric measures. Results: We found no statistically significant associations between prenatal PBDEs and height or weight z-score. A 10-fold increase in maternal serum BDE-153 was associated with lower BMI z-score (β = –0.36; 95% CI: –0.60, –0.13) at 2–8 years, smaller waist circumference (β = –1.81 cm; 95% CI: –3.13, –0.50) at 4–8 years, and lower percent body fat (β = –2.37%; 95% CI: –4.21, –0.53) at 8 years. A decrease in waist circumference at 4–8 years was observed with a 10-fold increase in BDE-100 (β = –1.50 cm; 95% CI: –2.93, –0.08) and ΣPBDEs (β = –1.57 cm; 95% CI: –3.11, –0.02). Conclusions: Reverse causality may have resulted in prenatal PBDEs, particularly BDE-153, and decreased BMI, waist circumference, and body fat.

    The Landsat series of satellites provides high quality, consistent, 30 m resolution data for studies of landscape-scale change over time at no cost to the user. The availability of the Landsat data archive and the effectiveness and ease of its use to solve practical societal problems, particularly integrated with Geographic Information Systems (GIS), has been a key factor in a movement to bring remote sensing education to community colleges (as in the "iGETT" program funded by the National Science Foundation, 2007-2011) and now to younger students of high school age. "Integrated Geospatial Education and Technology Training for High School Age Youth (HiGETT)" was a two-day meeting convened April 4-5, 2011 to explore and articulate effective means of reaching teens with geospatial technology education and career awareness. Participants represented industry, government, academia, and informal education organizations such as 4-H and Girl Scouts. This poster will summarize a report on that meeting.

    Background: Adult height, weight, and adiposity measures have been suggested by some studies to be predictors of depression, cognitive impairment, and dementia. However, the presence of confounding factors and the lack of a thorough neuropsychological evaluation in many of these studies have precluded a definitive conclusion about the influence of anthropometric measures in cognition and depression. In this study we aimed to assess the value of height, weight, and abdominal perimeter to predict cognitive impairment and depressive symptoms in aged individuals. Methods and Findings: Cross-sectional study performed between 2010 and 2012 in the Portuguese general community. A total of 1050 participants were included in the study and randomly selected from local area health authority registries. The cohort was representative of the general Portuguese population with respect to age (above 50 years of age) and gender. Cognitive function was assessed using a battery of tests grouped in two dimensions: general executive function and memory. Two-step hierarchical multiple linear regression models were conducted to determine the predictive value of anthropometric measures in cognitive performance and mood before and after correction for possible confounding factors (gender, age, school years, physical activity, alcohol consumption, and smoking habits). We found single associations of weight, height, body mass index, abdominal perimeter, and age with executive function, memory and depressive symptoms. However, when included in a predictive model adjusted for gender, age, school years, and lifestyle factors only height prevailed as a significant predictor of general executive function (β = 0.139; p < 0.001) and memory (β = 0.099; p < 0.05). No relation was found between mood and any of the anthropometric measures studied. Conclusions and Relevance: Height is an independent predictor of cognitive function in late-life and its effects on the general and executive function and

    A method of visual estimation of the biological age of living hungry tick females by visible changes in the depth of marginal groove and the structure of the alloscutum cuticle during natural ageing is developed. In recently activated individuals, the body is convex and the marginal groove is exposed, demonstrating distinctly visible cuticular microfolds (Figs 1-4). In attenuated ticks, the body is flattened and marginal fold overlays the marginal groove, concealing cuticular microfolds (Figs 5-8).

    Background Studies that evaluate both body composition and metabolic syndrome (MeS) risk in prepubertal children with premature adrenarche (PA) are limited. Methods Fifty-eight prepubertal children (5-9 years, 33F and 25M), with PA(n=30) and controls (n=28) were evaluated for the presence of MeS as defined by age-modified NCEP ATP III criteria. A subset had dual-energy x-ray absorptiometry and bone markers (n=23/58) to evaluate the effect of hyperandrogenism on metabolic abnormalities and body composition. Results There was no difference in prevalence of MeS between PA and controls(p=0.138). Children with MeS were obese with increased WC and decreased HDL levels. Androgens were not associated with having more than one criteria for MeS (p=0.08), but were associated with triglycerides and WC (p=0.029, p=0.041). Lean mass was greater in PA (p=0.039) and androgens correlated with BMD(p=0.029) and total body fat(p=0.008). Subjects with higher percent body fat were more likely to have more than one MeS risk factor(p=0.005). Conclusions MeS was seen only in obese subjects whether or not they had PA. Thus, it appears that obesity drives metabolic risk in the prepubertal population, rather than PA. Our findings are important in determining how the prepubertal patient with PA should be evaluated for metabolic risk. PMID:26513727

    Little is known about adipocyte metabolism during aging process and whether this can influence body fat redistribution and systemic metabolism. To better understand this phenomenon, two animal groups were studied: young-14 weeks old-and middle-aged-16 months old. Periepididymal (PE) and subcutaneous (SC) adipocytes were isolated and tested for their capacities to perform lipolysis and to incorporate D-[U-(14)C]-glucose, D-[U-(14)C]-lactate, and [9,10(n)-(3)H]-oleic acid into lipids. Additionally, the morphometric characteristics of the adipose tissues, glucose tolerance tests, and biochemical determinations (fasting glucose, triglycerides, insulin) in blood were performed. The middle-aged rats showed adipocyte (PE and SC) hypertrophy and glucose intolerance, although there were no significant changes in fasting glycemia and insulin. Furthermore, PE tissue revealed elevated rates (+50 %) of lipolysis during beta-adrenergic-stimulation. There was also an increase (+62 %) in the baseline rate of glucose incorporation into lipids in the PE adipocytes, while these PE cells were almost unresponsive to insulin stimulation and less responsive (a 34 % decrease) in the SC tissue. Also, the capacity of oleic acid esterification was elevated in baseline state and with insulin stimulus in the PE tissue (+90 and 82 %, respectively). Likewise, spontaneous incorporation of lactate into lipids in the PE and SC tissues was higher (+100 and 11 %, respectively) in middle-aged rats. We concluded that adipocyte metabolism of middle-aged animals seems to strongly favor cellular hypertrophy and increased adipose mass, particularly the intra-abdominal PE fat pad. In discussion, we have interpreted all these results as a metabolic adaptations to avoid the spreading of fat that can reach tissues beyond adipose protecting them against ectopic fat accumulation. However, these adaptations may have the potential to lead to future metabolic dysfunctions seen in the senescence.

    Background Bioelectrical impedance analysis (BIA) is a convenient and child-friendly method for longitudinal analysis of changes in body composition. However, most validation studies of BIA have been performed on adult Caucasians. The present cross-sectional study investigated the validity of two portable BIA devices, the Inbody 230 (BIA8MF) and the Tanita BC-418 (BIA8SF), in healthy Taiwanese children. Methods Children aged 7–12 years (72 boys and 78 girls) were recruited. Body composition was measured by the BIA8SF and the BIA8MF. Dual X-ray absorptiometry (DXA) was used as the reference method. Results There were strong linear correlations in body composition measurements between the BIA8SF and DXA and between the BIA8MF and DXA. Both BIAs underestimated fat mass (FM) and percentage body fat (%BF) relative to DXA in both genders The degree of agreement in lean body mass (LBM), FM, and %BF estimates was higher between BIA8MF and DXA than between BIA8SF and DXA. The Lin’s concordance correlation coefficient (ρc) for LBM8MF met the criteria of substantial to perfect agreement whereas the ρc for FM8MF met the criteria of fair to substantial agreement. Bland-Altman analysis showed a clinically acceptable agreement between LBM measures by BIA8MF and DXA. The limit of agreement in %BF estimation by BIA and DXA were wide and the errors were clinically important. For the estimation of ALM, BIA8SF and BIA8MF both provided poor accuracy. Conclusions For all children, LBM measures were precise and accurate using the BIA8MF whereas clinically significant errors occurred in FM and %BF estimates. Both BIAs underestimated FM and %BF in children. Thus, the body composition results obtained using the inbuilt equations of the BIA8SF and BIA8MF should be interpreted with caution, and high quality validation studies for specific subgroups of children are required prior to field research.

    Previous research from our Laboratory has shown a greater susceptibility of young animals, when compared to adults, to envenomation by tityustoxin (TsTX), one of the main toxins from Tityus serrulatus scorpion venom. Our hypothesis is that a differential body distribution of TsTX among adult and young animals could account for the worse prognosis of scorpion envenomation in infants. Thus, TsTX labeled with technetium-99m was injected (6 microg, subcutaneous) in adult (150-160 day-old) and young (21-22 day-old) male rats. Groups of animals were sacrificed at different times after TsTX injection (0.08, 1.0, 3.0, 6.0, 12.0 and 24.0 hours) under Urethane anesthesia (140 mg/100 g, i.p.). The brain, heart, lungs, liver, kidneys, spleen and thyroid were excised and blood collected. Young rats presented a shorter latency toxin concentration peak in all studied organs except for the liver and the kidney, when compared to adults. The ratio between the area under the curve of the toxin concentration in each organ and that in blood (Kp) indicates higher accumulation in the organs of young animals mainly for brain, liver and heart. These observations suggest a faster toxin distribution in the organs of young rats. The higher uptake of TsTX in the brain is suggestive of a greater permeability for the toxin along the blood-brain barrier of young rats. In conclusion, the higher uptake in heart, together with data from the brain, may help to elucidate the clinical manifestations frequently observed in children under scorpion envenomation.

    This study investigated body image issues and the usefulness of self-reported measurements among Hmong American children, 9-18 years using mixed methodology. Twelve focus groups were conducted (n=68) and a silhouette drawing instrument and six questions pertaining to body image were administered (n=335). About 50% of the children were either overweight or obese and 23% were short statured relative to US norms. About 70% of the girls and 53% of the boys selected smaller body ideals than their perceived body sizes. Further, 21% of the girls and 31% of the boys were satisfied with their bodies. Children underestimated their weights and overestimated their heights. During focus groups children reported that parents, peers, and media influenced their body image perceptions. Our results indicate that the majority of Hmong children are dissatisfied with their bodies and tend to endorse American ideals of beauty and attractiveness rather than the heavier, traditional Hmong body ideals supported by their parents.

    Merino sheep in Australia experience periods of variable feed supply. Merino sheep can be bred to be more resilient to this variation by losing less BW when grazing poor quality pasture and gaining more BW when grazing good quality pasture. Therefore, selection on BW change might be economically attractive but correlations with other traits in the breeding objective need to be known. The genetic correlations (rg) between BW, BW change, and reproduction were estimated using records from approximately 7,350 fully pedigreed Merino ewes managed at Katanning in Western Australia. Number of lambs and total weight of lambs born and weaned were measured on approximately 5,300 2-yr-old ewes, approximately 4,900 3-yr-old ewes, and approximately 3,600 4-yr-old ewes. On a proportion of these ewes BW change was measured: approximately 1,950 2-yr-old ewes, approximately 1,500 3-yr-old ewes, and approximately 1,100 4-yr-old ewes. The BW measurements were for 3 periods. The first period was during mating period over 42 d on poor pasture. The second period was during pregnancy over 90 d for ewes that got pregnant on poor and medium quality pasture. The third period was during lactation over 130 d for ewes that weaned a lamb on good quality pasture. Genetic correlations between weight change and reproduction were estimated within age classes. Genetic correlations were tested to be significantly greater magnitude than 0 using likelihood ratio tests. Nearly all BW had significant positive genetic correlations with all reproduction traits. In 2-yr-old ewes, BW change during the mating period had a positive genetic correlation with number of lambs weaned (rg = 0.58); BW change during pregnancy had a positive genetic correlation with total weight of lambs born (rg = 0.33) and a negative genetic correlation with number of lambs weaned (rg = -0.49). All other genetic correlations were not significantly greater magnitude than 0 but estimates of genetic correlations for 3-yr-old ewes were

    The current study investigated the effect of education on retrospective metamemory accuracy in 143 healthy older adults and 143 early to moderate AD patients, using retrospective measures of confidence in the accuracy of retrieval responses in an episodic odor recognition memory task. Relative confidence accuracy was computed as the difference between confidence judgments for correct and incorrect responses. In both AD patients and controls, individuals reporting 17 years of education or more had significantly more accurate levels of confidence than individuals with 12 years or less. Thus, education was a significant predictor of retrospective metamemory accuracy in healthy aging and AD. PMID:24131064

    In this study, we developed a statistical rib cage geometry model accounting for variations by age, sex, stature and body mass index (BMI). Thorax CT scans were obtained from 89 subjects approximately evenly distributed among 8 age groups and both sexes. Threshold-based CT image segmentation was performed to extract the rib geometries, and a total of 464 landmarks on the left side of each subject׳s ribcage were collected to describe the size and shape of the rib cage as well as the cross-sectional geometry of each rib. Principal component analysis and multivariate regression analysis were conducted to predict rib cage geometry as a function of age, sex, stature, and BMI, all of which showed strong effects on rib cage geometry. Except for BMI, all parameters also showed significant effects on rib cross-sectional area using a linear mixed model. This statistical rib cage geometry model can serve as a geometric basis for developing a parametric human thorax finite element model for quantifying effects from different human attributes on thoracic injury risks.

    As the need for gerontological social workers increases, it is important to assess faculty interest in strengthening and bolstering this area in the classroom and curriculum. This study sought to compare training and experience of social work faculty that identified aging as a teaching or research interest with faculty who did not, and to identify predictors of aging interest among faculty. A national sample of social work faculty members was recruited, and a total of 609 individuals participated in the study. The findings reveal that faculty with an interest in aging differed from nonaging faculty in the areas of knowledge of older adults, personal and paid experience, and graduate and continuing education. In addition, predictors of interest in aging included taking a graduate course, continuing education units, having paid and volunteer experience, level of knowledge of older adults, and comfort level of covering content on aging in the classroom. The connection between social work faculty and student interest in aging are discussed as implications for further social work research and education.
