- Background: Few published data link overweight and obesity with measures of quality of life (QoL) including sexual health in men. Objective: To assess the association of overweight/obesity with impairment of physical and psychological QoL and sexual functions in men. Design and setting: Cross-sectional, multicentre survey of 3369 community-dwelling men aged 40-79 (mean +/- S.D., 60 +/- 11) years randomly selected from eight European centres. Outcomes: Adiposity was assessed by body mass index (BMI) and waist circumference (WC), QoL and functional impairments by physical and psychological function domains of the Short Form-36 questionnaire, Beck's Depression Inventory and the European Male Ageing Study sexual function questionnaire. Results: Complete data on sexual activities and erectile function were available in 2734 (92%) and 3193 (95%) of the participants respectively. From the population studied, 814 men were obese (BMI >= 30 kg/m(2)) and 1171 had WC >= 102 cm, 25% of all men were unable to do vigorous activity and 2-13% reported depressive symptoms. Symptoms of sexual dysfunction ranged between 22% (low sexual desire) and 40% (infrequent morning erections) of the participants. Among obese men with both BMI >= 30 kg/m(2) and WC >= 102 cm, at least one symptom of impaired physical, psychological and sexual function was reported by 41, 43 and 73% of the participants respectively. Compared with the reference group of non-obese men (BMI < 30 kg/m(2) and WC < 102cm), men with BMI >= 30 kg/m(2) and WC >= 102 cm more frequently reported at least one symptom of impaired physical function (odds ratio (OR)=2.67; confidence interval (CI): 2.07-3.45, P < 0.001), impaired psychological function (OR=1.48; CI: 1.14-1.90, P < 0.01) and impaired sexual function (OR=1.45; CI: 1.14-1.85, P < 0.01). These functional impairments were also more prevalent in men who had WC >= 102 cm even with BMI < 30 kg/m(2), but those with BMI >= 30 kg/m(2) and WC < 102 cm generally did not suffer from increased impaired physical or sexual health. Men with high BMI and WC were at even greater likelihood of having a composite of two or more or three or more symptoms compared with those with normal BMI and WC. Conclusions: Men with high WC, including those who are 'non-obese' with BMI < 30 kg/m(2), have poor QoL with symptoms of impaired physical, psychological and sexual functions. Health promotion to improve QoL should focus on prevention of obesity and central fat accumulation.

- Background: The limitations of serum testosterone and estradiol (E-2) measurements using nonextraction platform immunoassays (IAs) are widely recognized. Switching to more specific mass spectrometry (MS)-based methods has been advocated, but directly comparative data on the two methods are scarce. Methods: We compared serum testosterone and E-2 measurements in a large sample of middle-aged/elderly men using a common platform IA and a gas chromatography (GC)-MS method, in order to assess their limitations and advantages, and to diagnose male hypogonadism. Of subjects from the European Male Aging Study (n = 3174; age 40-79 years), peripheral serum testosterone and E-2 were analyzed using established commercial platform IAs (Roche Diagnostics E170) and in-house GC MS methods. Results: Over a broad concentration range, serum testosterone concentration measured by IA and MS showed high correlation (R=0.93, P<0.001), which was less robust in the hypogonadal range (<11 nmol/l; R=0.72, P<0.001). The IA/MS correlation was weaker in E-2 measurements (R=0.32, P<0.001, at E-2 <40.8 pmol/l, and R=0.74, P<0.001, at E-2 >40.8 pmol/l). Using MS as the comparator method, IA ascertained low testosterone compatible with hypogonadism (<11 nmol/l), with 75% sensitivity and 96.3% specificity. The same parameters with IA for the detection of low E-2 (<40.7 pmol/l) were 13.3 and 99.3%, and for high E-2 (>120 pmol/l) 88.4 and 88.6%. Conclusion: A validated platform IA is sufficient to detect subnormal testosterone concentrations in the diagnosis of male hypogonadism. The IA used for E-2 measurements showed poor correlation with MS and may only be suitable for the detection of high E-2 in men.

- Setting: prospective cohort analysis within the European Male Ageing Study. Participants: 2,816 community-dwelling men aged 40-79 years at baseline. Methods: Cox regression was used to examine the association of all-cause mortality with 25(OH)D, 1,25(OH)(2)D and PTH; cardiovascular and cancer mortality were modelled using competing-risks regression. Results were expressed as hazard ratios (HR) and 95% confidence intervals (CIs) for Cox models; sub-hazard ratios (SHR) and 95% CIs for competing-risks models. Results: a total of 187 men died during a median of 4.3 years of follow-up. Serum levels of 25(OH)D (per 1 SD decrease: HR = 1.45; 95% CI = 1.16, 1.81) and 1,25(OH)(2)D (per 1 SD decrease: HR = 1.20; 95% CI = 1.00, 1.44) were associated with an increased risk of all-cause mortality after adjusting for age, centre, smoking, self-reported morbidities, physical activity and functional performance. Only levels of 25(OH)D < 25 nmol/l predicted cancer mortality (SHR = 3.33; 95% CI = 1.38, 8.04). Conclusion: lower 25(OH)D and 1,25(OH)(2)D levels independently predicted all-cause mortality in middle-aged and older European men. Associations with cancer mortality were only observed among men with very low levels of 25(OH)D. These associations were only partially explained by the range of adverse health and lifestyle factors measured here.

- Background. There has been little research on how late-life frailty interrelates with sexual health. Our objective was to examine the association of frailty with sexual functioning and satisfaction among older men. Methods. The study population consisted of 1,504 men aged 60 to 79 years, participating in the European Male Aging Study. Self-report questionnaires measured overall sexual functioning, sexual function related distress, and erectile dysfunction. Frailty status was defined using a phenotype (FP) or index (FI). Associations between frailty and sexual function were explored using regression models. Results. Based on the frailty phenotype, 5% of men were classified as frail, and the mean frailty index was 0.18 (SD = 0.12). Frailty was associated with decreasing overall sexual functioning and increasing sexual function related distress in multiple linear regressions adjusted for age, smoking, alcohol consumption, living arrangements, comorbidities, and depression. Frailty was also associated with an increased odds of erectile dysfunction after adjustment for the same confounders: odds ratio = 1.99 (95% confidence interval = 1.14, 3.48) and 4.08 (95% confidence interval = 2.63, 6.36) for frailty phenotype and frailty index, respectively. Conclusions. Frailty was associated with impaired overall sexual functioning, sexual function related distress, and erectile dysfunction. Individuals assessed for frailty-related deficits may also benefit from an appraisal of sexual health as an important aspect of well-being and quality of life.

- Few studies have directly compared the ability of the most commonly used models of frailty to predict mortality among community-dwelling individuals. Here, we used a frailty index (FI), frailty phenotype (FP), and FRAIL scale (FS) to predict mortality in the EMAS. Participants were aged 40-79 years (n = 2929) at baseline and 6.6% (n = 193) died over a median 4.3 years of follow-up. The FI was generated from 39 deficits, including self-reported health, morbidities, functional performance and psychological assessments. The FP and FS consisted of five phenotypic criteria and both categorized individuals as robust when they had 0 criteria, prefrail as 1-2 criteria and frail as 3+ criteria. The mean FI increased linearly with age (r(2) = 0.21) and in Cox regression models adjusted for age, center, smoking and partner status the hazard ratio (HR) for death for each unit increase of the FI was 1.49. Men who were prefrail or frail by either the FP or FS definitions, had a significantly increased risk of death compared to their robust counterparts. Compared to robust men, those who were FP frail at baseline had a HR for death of 3.84, while those who were FS frail had a HR of 3.87. All three frailty models significantly predicted future mortality among community-dwelling, middle-aged and older European men after adjusting for potential confounders. Our data suggest that the choice of frailty model may not be of paramount importance when predicting future risk of death, enabling flexibility in the approach used. (C) 2013 Elsevier Ireland Ltd.

- Background: the link between the vitamin D endocrine axis and frailty remains undefined, with few studies examining the joint effect of vitamin D and parathyroid hormone (PTH) levels. Our objective was to determine the association of frailty with serum 25-hydroxyvitamin D (25(OH) D) and PTH. Setting: cross-sectional analysis within the European Male Ageing Study (EMAS). Participants: a total of 1,504 community-dwelling men aged 60-79 years. Methods: frailty was classified using a frailty phenotype (FP) and frailty index (FI). The association of frailty with 25(OH)D and PTH was examined using multinomial logistic regression; individual FP criteria with 25(OH)D and PTH using binary logistic regression. Results were expressed as relative odds ratios (ROR) and 95% confidence intervals (CIs) for multinomial; odds ratios (OR) and 95% CIs for binary models. Results: using the FP, 5.0% of subjects were classified as frail and 36.6% as prefrail. Lower levels of 25(OH)D were associated with being prefrail (per 1 SD decrease: ROR = 1.45; 95% CI: 1.26-1.67) and frail (ROR = 1.89; 95% CI: 1.30-2.76), after adjusting for age, centre and health and lifestyle confounders (robust group = base category). Higher levels of PTH were associated with being frail after adjustment for confounders (per 1 SD increase: ROR = 1.24; 95% CI: 1.01-1.52). Comparable results were found using the FI. Among the five FP criteria only sarcopenia was not associated with 25(OH)D levels, while only weakness was associated with PTH. Conclusion: lower 25(OH)D and higher PTH levels were positively associated with frailty in older men. Prospective data would enable the temporal nature of this relationship to be explored further.
