Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); BACKGROUND: The one repetition maximum (1RM) test is the most widely used method to analyze muscular strength. However, the 1RM reliability may be dependent on gender.OBJECTIVE: The purpose of the study was to investigate the reliability of one-repetition maximum (1RM) test in untrained young adult men and women.METHODS: Thirteen men and eleven women between 18-35 years were recruited. All subjects performed the 1RM tests in the bench press (BP), Smith machine squat (SQ), and arm curl (AC) in four sessions separated by 48 to 72 hours of recovery. At each measurement session, the subjects performed exercise-specific warm-ups and were given three attempts to reach a peak strength level for each exercise.RESULTS: There was a significant session-by-time interaction (P < 0.05) in BP and SQ, while men reached a stabilized load between sessions 2-3, women stabilized their load between sessions 1-2. Significant increases (P < 0.05) in maximal strength occurred between session 1 and 4 in BP (men = + 10.5%, women = + 13.1%), SQ (men = +17.6%, women = +20.7%), and AC (men = +7.5%, women = +11.7%).CONCLUSION: We conclude that the reliability of the 1RM tests in multiple-joint exercises may be gender dependent.

The objective of this study was to verify factors associated with the use of medication by adults, with emphasis on the differences between men and women. It was a population-based, cross-sectional study with cluster sampling conducted in two stages in Campinas in the state of São Paulo in 2008. Among the 2,413 individuals aged 20 or older, the prevalence of use of at least one drug in the three days before the research was 45.4% (95% CI: 41.3 - 49.4) in men and 64.6% (95% CI: 59.8 - 69.2) in women. For adult men over 40 years old who were not working, former smokers, with one or more chronic diseases, with two or more health problems and who sought health care or a health professional in the two weeks preceding the research showed higher prevalence of medication use. Among women, a higher prevalence of use was observed in females over 40, obese, former smokers, who reported a short sleep pattern, with one or more chronic diseases and two or more health problems, and who reported seeking a health care service or professional in the past 15 days. The findings showed some differences in the determinants of drug use in relation to gender, revealing the greater importance of health-related behavior among women.

Experimental animal studies have demonstrated that exposure to some phthalates may be associated with altered endocrine function and adverse effects on male reproductive development and function, but human studies are limited. In the present study, urine and serum samples were collected from 425 men recruited through a US infertility clinic. Urinary concentrations of mono(2-ethylhexyl) phthalate (MEHP), the hydrolytic metabolite of di(2-ethylhexyl) phthalate (DEHP), and other phthalate monoester metabolites were measured, along with serum levels of testosterone, estradiol, SHBG, FSH, LH, inhibin B and prolactin. Two oxidized urinary metabolites of DEHP were also measured in urine from 221 of the men. In multiple regression models adjusted for potential confounders, MEHP was inversely associated with testosterone, estradiol, and free androgen index (FAI). An interquartile range increase in MEHP was associated with 4% (95%CI −7% to −1%) and 7% (95%CI −11% to −2%) declines in testosterone and estradiol, respectively, relative to the population median hormone levels. There was limited evidence for effect modification of the inverse association between MEHP and FAI by the proportion of DEHP metabolites in the urine measured as MEHP (MEHP%)...

Aging is associated with decreased skeletal muscle function. Increased levels of advanced glycation end products (AGEs) in skeletal muscle tissue are observed with advancing age and in diabetes. Although serum AGE level is negatively associated with grip strength in elderly people, it is unknown whether this association is present in adult males. To determine the relationship between AGE accumulation in tissue and muscle strength and power among Japanese adult men. Skin autofluorescence (AF) (a noninvasive method for measuring tissue AGEs), grip strength (n = 232), and leg extension power (n = 138) were measured in Japanese adult men [median (interquartile range) age, 46.0 (37.0, 56.0) years]. After adjustment for potential confounders, the adjusted means [95% confidence interval (CI)] for grip strength across the tertiles of skin AF were 44.5 (43.2, 45.9) kg for the lowest tertile, 42.0 (40.6, 43.3) kg for the middle tertile, and 41.7 (40.3, 43.1) kg for the highest tertile (P for trend < 0.01). Moreover, the adjusted geometric means (95% CI) of leg extension power across the tertiles of skin AF were 17.8 (16.6, 19.1) W/kg for the lowest tertile, 17.5 (16.4, 18.7) W/kg for the middle tertile, and 16.0 (14.9, 17.1) W/kg for the highest tertile (P for trend = 0.04). Among Japanese adult men...

We compared quantitative diary data with retrospective survey data collected from a cohort of young adult men who have sex with men (MSM) in Seattle, Washington. Ninety-five MSM, aged 16–30 years, completed web-based surveys every 3 months and were randomized to 4 diary submission schedules: every 2 weeks, once a week, twice a week, or never. We calculated diary completion rates and assessed agreement between daily diary data and aggregate retrospective survey data for sexual behavior measures. Over 6 months, 78% of participants completed at least 80% of their diary days, and the 2-week schedule had the highest and most consistent completion rate. The majority of sexual behavior and substance use measures had strong agreement between the diary and retrospective survey data (i.e., kappa>0.80 or concordance correlation coefficient ≥ 0.75), although we observed poorer agreement for some measures of numbers of anal sex acts. There were no significant differences in mean responses across diary schedules. We observed some evidence of reactivity (i.e., a difference in behavior associated with diary completion). Participants not assigned diaries reported significantly more unprotected anal sex acts and were more likely to be newly diagnosed with HIV or another sexually transmitted infection compared to those assigned active diary schedules. This study suggests that sexual behavior data collected from young adult MSM during 3-month retrospective survey—an interval commonly used in sexual behavior research—are likely valid. Diaries...

The purpose of this study was to determine the relationship between unilateral squat strength and measures of static balance to compare balance performance between the dominant and non-dominant leg. Seventeen apparently healthy men (mean mass 90.5 ± 20.9 kg and age 21.7 ± 1.8 yrs) and 25 women (mean mass 62.2 ± 14.5 kg and age 21.9 ± 1.3 yrs) completed the study. Weight bearing unilateral strength was measured with a 1RM modified unilateral squat on the dominant and non-dominant leg. The students completed the stork stand and wobble board tests to determine static balance on the dominant and non-dominant leg. Maximum time maintained in the stork stand position, on the ball of the foot with the uninvolved foot against the involved knee with hands on the hips, was recorded. Balance was measured with a 15 second wobble board test. No significant correlations were found between the measurements of unilateral balance and strength (r values ranged between -0.05 to 0.2) for the men and women. Time off balance was not significantly different between the subjects’ dominant (men 1.1 ± 0.4 s; women 0.3 ± 0.1 s) and non-dominant (men 0.9 ± 0.3 s; women 0.3 ± 0.1 s) leg for the wobble board. Similar results were found for the time balanced during the stork stand test on the dominant (men 26.4 ± 6.3 s; women 24.1 ± 5.6 s) and non-dominant (men 26.0 ± 5.7 s; women 21.3 ± 4.1 s) leg. The data indicate that static balance and strength is unrelated in young adult men and women and gains made in one variable after training may not be associated with a change in performance of the other variable. These results also suggest that differences in static balance performance between legs can not be determined by leg dominance. Similar research is needed to compare contralateral leg balance in populations who participate in work or sport activities requiring repetitive asymmetrical use. A better understanding of contralateral balance performance will help practitioners make evaluative decisions during the rehabilitation process.

Studies investigating possible associations between iron status and mood or depressive symptoms have reported inconsistent results. However, they have neither used body iron to measure iron status nor measured mood using daily measures. We investigated whether body iron was associated with depressive symptoms, daily mood, daily tiredness, difficulty concentrating, and stress in young adult women and men. Young adult (17–25 years) women (n = 562) and men (n = 323) completed the Center for Epidemiologic Studies Depression Scale, then reported negative and positive mood, and other states daily for 13 days. Non-fasting venous blood was collected to determine hemoglobin, serum ferritin and soluble transferrin receptor (to calculate body iron), C-reactive protein, and alpha-1-acid glycoprotein concentration. Regression models tested linear associations between body iron and the outcome variables, controlling for possible confounders. No associations were found between body iron and the outcome variables in women. However, higher body iron was associated with more depressive symptoms in men (3.4% more per body iron mg/kg; 95% confidence intervals (CI): 0.8%, 5.9%). In young adult women, body iron is unlikely to be associated with significant deficits in mood or depressive symptoms. However...

The countries of Central and Eastern Europe and Central Asia have a long history of striving for gender equality, especially in the public sphere. Not only was this an important goal during the socialist era, but governments continued to pursue gender equality even during the difficult years of transition. The governments in the region allocated substantial resources toward the health and education of both women and men. They also adopted legislation that treated women and men equally in the labor market and they provided child care services. During much of the last century, the region surpassed countries both developing and developed in establishing the equal treatment of women and men. This report reviews changes in gender inequalities in Europe and Central Asia over the last decade, with a particular focus on economic opportunities both in labor markets and in entrepreneurial activity. In addition, given the importance of health and education in opening up opportunities for men and women in the economic sphere...

Europe and Central Asia have suffered a setback in economic growth because of the recent global crisis, which revealed fundamental structural weaknesses previously hidden by the prosperity before the crisis. The major weaknesses are the large savings deficits, the lagging reforms in the social sectors, and the deterioration in competitiveness. Policies can address these weaknesses by taking into account the role of the behavior of firms, public spending on health and education, the consequences of demographic pressures, particularly on pension systems, and the bottlenecks created by skilled labor force shortages. This report reviews the performance of women and men during the past decade in three spheres: human capital, labor markets, and entrepreneurship. Similar to World Development Report 2012 (World Bank 2011a), it looks at the dimensions of endowments and economic opportunities. However, it does not cover issues related to agency, that is, the ability of actors to make independent choices and exercise control over their own actions. The data are analyzed to determine whether women and men are performing well compared with each other...

The novel peptide hormone insulin-like peptide 3 (INSL3) is a major secretory product of the Leydig cells of the testis, and in adult men is secreted into the blood, giving rise to circulating concentrations ranging from 0.5 to 2.5 ng/mL. We studied a large randomly recruited cohort of 1183 men from South Australia, comparing serum INSL3 concentrations with age, and a variety of endocrine, cognitive and morphological parameters. While INSL3 concentration declines significantly (p < 0.001) and continuously with age from 1.29 ± 0.47 ng/mL in young men (age 35–44 years) to 0.79 ± 0.39 ng/mL in the age group 75–80 years, there is no correlation with testosterone or components of the hypothalamo-pituitary-gonadal (HPG) axis, independent of age, nor with any other parameter measured, including thyroid or prostate status and obesity. For men exhibiting normal follicle stimulating hormone (FSH) and high luteinizing hormone (LH) levels, there was a significant inverse correlation with plasma oestradiol. Unilaterally orchidectomized men had INSL3 values intermediate between intact men and anorchid subjects, and showed inverse correlations (p < 0.001) between INSL3 and FSH or LH concentrations, which were independent of age. Taken together...

Background: There is uncertainty about the calcium requirement with particular respect to age and sex differences and the calculation of skin calcium losses. Objective: We calculated the calcium requirement of adult men from a homogenous set of calcium balances and a robust estimate of calcium loss through the skin. Design: We reviewed available high-quality published calcium balances in men and retrieved 219 balances; we noted a fall in calcium absorption in individuals >60 y of age. Our analysis was confined to 157 men ≤59 y of age with intakes of ≤1100 mg Ca. Results: The mean age of the men was 38 y (range: 17–59 y), and the mean duration of the balances was 107 d (9–480 d). We assumed skin calcium losses of 40 mg Ca/d on the basis of the calcium content of insensible water loss. There was a highly significant correlation between calcium intake and the net absorbed calcium (R2 = 0.59), but inspection and physiologic considerations led us to use the logarithmic transformation of intake, which yielded the equation Ca absorbed = 210 log Ca intake − 1135 mg Ca. The calcium intake at which urine calcium plus skin calcium losses were equal to the net absorbed calcium was rounded to 750 mg Ca as the requirement, which implied a recommended allowance of 900 mg Ca. Conclusion: We conclude that the mean calcium requirement of adult men <60 y of age is 750 mg Ca/d...

BACKGROUND. This cross-sectional study was performed to determine the reference ranges for two bone turnover markers -aminoterminal propeptide of type I collagen (P1NP) and C-terminal telopeptide of type I collagen (-CTX)- in normal adult Spanish men as measured in serum by automated methods. METHODS. A community-based population of 660 healthy men ≥ 50 years was evaluated. Fasting serum levels of P1NP, -CTX, 25-hydroxivitamin D, and intact parathyroid hormone were measured on the Elecsys 2010 automated analyzer (Roche). BMD at lumbar spine, femoral neck and total hip was determined by DXA. RESULTS. Mean age of participants was 65±9 yrs. Logarithmic transformation of both markers was performed to allow for normal distribution. Mid-95% ranges for P1NP and -CTX were 15-78 ng/ml and 0.069-0.760 ng/ml, respectively. Median and interquartile range of serum P1NP and -CTX were 33.5 [25.5;44.4] ng/ml and 0.27 [0.19;0.38] ng/ml, respectively. Mean values of P1NP (37.1±16.7 ng/ml) were similar to those previously described. -CTX mean values (0.300±0.171 ng/ml) were also similar to those quoted by the manufacturers in men younger than 70 yrs, but slightly lower than those reported in subjects older than 70 yrs. Both markers were higher among osteoporotic men. After excluding from the analysis those men who were found to have BMD below -2.5 T-score...

This report describes the demographic transition in the Russian Federation and its implications for adult learning and long-term care policies. The population of Russia is aging and declining rapidly compared to other European nations. Russia's current age structure results from decades of complex demographic trends that have created a population structure with increasingly fewer young people. Women are having fewer children and are waiting longer to have children. Russia's mortality remains higher than in other developed societies. This high mortality is due to an unusually high incidence of non-communicable diseases (NCDs) and injuries among adult men. Two key challenges face Russia. The first challenge is whether public expenditure on pensions and health care will become unsustainable as the size of the elderly population increases. The second challenge is whether declining population sizes will reduce the size of the labor force and hence reduce economic growth.

This report provides tremendous insight on gender norms an area that has been resistant to change, and that constrains achievement of gender equality across many diverse cultures. The report synthesizes data collected from more than 4,000 women and men in 97 communities across 20 countries. It is the largest dataset ever collected on the topic of gender and development, providing an unprecedented opportunity to examine potential patterns across communities on social norms and gender roles, pathways of empowerment, and factors that drive acute inequalities. The analysis raises the profile of persistent social norms and their impact on agency, and catalyzes discourse on the many pathways that create opportunities for women and men to negotiate transformative change. The report is underpinned by the fact that arguably the single most important contribution to development is to unleash the full power of half the people on the planet women. It underscores how crucial making investments in learning, supporting innovations that reduce the time costs of women s mobility...

Circumcision—the surgical removal of some/all of the male prepuce (foreskin)—is among the oldest and most common surgical procedures globally. Research on circumcision—and the recent North American policy endorsing it—focuses on health outcomes; sexual correlates of circumcision remain largely unexplored. A review of the circumcision literature was conducted (Chapter 2), and four studies investigated the sexual correlates of neonatal circumcision. Chapter 3 employed quantitative sensory testing (detection/pain thresholds using punctate/thermal stimuli) to examine penile sensitivity in healthy adult men (circumcised, intact). Findings indicate minimal differences across circumcision status. Chapter 4, which compared sexual functioning across circumcision status, found no significant differences between circumcised and intact men with respect to genital response (via laser Doppler imaging: LDI), subjective experiences of sexual arousal, or sexual/urological history variables. Chapter 5 explored men’s attitudes towards their circumcision status and the implications of these attitudes on body image and sexual functioning. A proportion of circumcised men who completed this online survey indicated high distress about their circumcision status. Furthermore...

Objectives: Recent studies have shown that the choice of foods plays a role in diabetes prevention. However, little empirical evidence on this association exists in developing countries. We aimed to examine the association between frequency of fish intake and self-reported diabetes status among adult men and women in India. Methods: Analysis of cross-sectional data from participants in India's third National Family Health Survey conducted during 2005–2006 was performed. Associations between fish intake, determined by frequency of consumption (daily, weekly, occasionally, and never), and self-reported diabetes were estimated using multivariable-adjusted models in 99,574 women, 56,742 men, and 39,257 couples aged 20–49 years after adjusting for frequency of consumption of other food items, body mass index (BMI) status, tobacco smoking, alcohol drinking, watching television, age, education, living standard of the household, and place of residence. Results: After adjustment for other dietary, lifestyle, and socioeconomic and demographic characteristics, odds of diabetes were 2 times higher (odds ratio [OR]: 2.02; 95% confidence interval [CI], 1.59–2.57; p < 0.0001) among those who reported consuming fish daily compared to those who never consumed fish. Weekly fish intake was also associated with a higher odds of having diabetes (OR: 1.55; 95% CI...

This study aimed to investigate the correlations among androgen receptor (AR) CAG repeat polymorphism, sex hormones and penile length in healthy Chinese young adult men. Two hundred and fifty-three healthy men (aged 22.8 ± 3.1 years) were enrolled. The individuals were grouped as CAG short (CAGS) if they harbored repeat length of ≤20 or as CAG long (CAGL) if their CAG repeat length was >20. Body height/weight, penile length and other parameters were examined and recorded by the specified physicians; CAG repeat polymorphism was determined by the polymerase chain reaction (PCR) method; and the serum levels of the sex hormones were detected by radioimmunoassay. Student's t-test or linear regression analysis was used to assess the associations among AR CAG repeat polymorphism, sex hormones and penile length. This investigation showed that the serum total testosterone (T) level was positively associated with the AR CAG repeat length (P = 0.01); whereas, no significant correlation of T or AR CAG repeat polymorphism with the penile length was found (P = 0.593). Interestingly, an inverse association was observed between serum prolactin (PRL) levels and penile length by linear regression analyses (β= −0.024, P = 0.039, 95% confidence interval (CI): −0.047...

The aim of this study was to verify validity and reliability of the scores for physical exercise in leisure (PEL), leisure and locomotion activities (LLA), and total score (TS) of the Baecke habitual physical activity questionnaire in adult males. Twenty-one students of Physical Education were evaluated. For validation, the maximum oxygen uptake (O2max) and the decrease of the heart rate in percentile (%DHR) were measured through the Cooper's 12-minute walk or run test, and an annual index of physical exercise (IPE), and a week index of locomotion activities (ILA). The reliability was verified through test-retest with interval of 45 days. The Pearson correlation coefficient, and partial correlation adjusted for age and body mass index were used for validation. The intraclass correlation and paired t-test were used for reliability. The results indicated that %DHR was correlated with LLA and TS (r = 0.47 and p = 0.030; r = 0.48 and p = 0.027, respectively). IPE was correlated with PEL and TS (r = 0.56 and p = 0.008; r = 0.46 and p = 0.036, respectively). ILA was correlated with LLA and TS (r = 0.64 and p = 0.002 and r = 0.51 and p = 0.017, respectively). There was no significant difference in PEL...

peer-reviewed; Anthropometric data indicate that the human phenotype is changing. Today's adult is greater in stature, body mass and fat mass. Accurate measurement of body composition is necessary to maintain surveillance of obesity within the population and to evaluate associated interventions. The aim of the present study was to construct and validate generalised equations for percentage body fat (%BF) prediction from anthropometry in 1136 adult men and women. Reference values for %BF were obtained using dual-energy X-ray absorptiometry. Skinfold thickness (SF) at ten sites and girth (G) at seven sites were measured on 736 men and women aged 18-81 years (%BF 5.1-56.8%). Quantile regression was employed to construct prediction equations from age and log-transformed SF and G measures. These equations were then cross-validated on a cohort of 400 subjects of similar age and fatness. The following generalised equations were found to most accurately predict %BF:Men: (age x 0.1) + (logtricepsSF x 7.6) + (logmidaxillaSF x 8.8) + (logsuprspinaleSF x 11.9) - 11.3 (standard error of the estimate: 2.5%, 95% limits of agreement: -4.8, +4.9)Women: (age x 0.1) + (logabdominalG x 39.4) + (logmidaxillaSF x 4.9) + (logbicepsSF x 11.0) + (logmedialcalfSF x 9.1) - 73.5 (standard error of the estimate: 3.0%...

OBJECTIVE: To examine the relations between frequency of alcohol consumption and of binge drinking and adult mortality in Russian men and women. METHODS: Using modified indirect demographic techniques, a convenience cohort was constructed based on survey respondents' information about their close relatives. A random sample general population of the Russian Federation of 7172 respondents (response rate 61%) provided information on 10 475 male and 3129 female relatives, including age, vital status, and frequency of alcohol consumption and binge drinking. These relatives formed the cohort analysed in this report. The outcome measure was all-cause mortality after the age of 30 years. FINDINGS: There was a strong linear relation between frequency of drinking and of binge drinking and all-cause mortality in men; after controlling for smoking and calendar period of birth, the relative risk of death in daily drinkers compared to occasional drinkers was 1.52 (95% confidence interval (CI) 1.33-1.75). Male binge drinkers had higher mortality than drinkers who did not binge, which persisted after adjustment for drinking frequency (adjusted relative risk 1.09, 95% CI 1.00-1.19). In women, the increased mortality was confined to a small group of those who binged at least once a month (adjusted relative risk 2.68...
