However, few studies have reported the possible differences in the effect of obesity on outcomes between older adults with metabolic abnormalities and those without metabolic abnormalities. Methods A total of 3485 older men were included from 2000 to 2014. All-cause mortality and cardiovascular mortality were obtained during a mean follow-up of five years Metabolic abnormalities were defined as having established hypertension, diabetes, or dyslipidemia and taking the disease-related medications. All participants were stratified by the presence or absence of metabolic abnormalities. Results In the non-metabolic abnormalities group, all-cause and cardiovascular deaths were lowest in overweight participants and highest in obese participants. In the metabolic abnormalities group, mortality was also lowest in overweight participants but highest in participants with normal weight. After adjustment for covariates, hazard ratios （95% CI） for all-cause death and cardiovascular death were 0.68 （0.51, 0.92） and 0.59 （0.37, 0.93）, respectively, in overweight participants with metabolic abnormalities. Furthermore, obesity was not associated with mortality risk in both groups. These findings were unchanged in stratified analyses. Conclusions Overweight was negatively associated with mortality risk in older men with metabolic abnormalities but not in those without metabolic abnormalities. Obesity did not increase death risk regardless of metabolic abnormalities. These findings suggest that the recommendation of pursuing a normal weight may be wrong in overweight/obese older men, especially for those with metabolic abnormalities.展开更多

Methods: The participants were a group of 134 men, ≥65 years old, who required support and were living in Hokkaido, Japan. An anonymous questionnaire was administered through individual interviews. Valid responses were obtained from 121/134 interviewees. The construct validity of the resulting scale was assessed by exploratory factor analysis (EFA). Criterion-related validity was tested with Spearman’s rank correlation test based on the Social Activities Index for Elderly People (SAI-E). Reliability was assessed by Cronbach’s alpha. Results: A Social Activities Scale for Community-dwelling Older Men Requiring Support (SASOMS) scale was created, comprised of the following three subscales: daily interactions with familiar people;intimate relationships with family members;and interactions with others through activity programs (e.g., exercise, games, recreation, etc.). The created SASOMS scale correlated with the SAI-E (r = 0.557), and its criterion-related validity was confirmed. The alpha coefficient of the new scale was 0.791, and its internal consistency was confirmed. Conclusions: The reliability and validity of the developed SASOMS scale was confirmed, demonstrating that it can be used to assess social activities specifically in older men requiring support. Our results suggest that the scale can be used effectively by care providers who support older men requiring care. The usability of the SASOMS should continue to be improved, and it is necessary to verify its validity in longitudinal studies.展开更多

Triglycerides, glucose and high-density lipoprotein cholesterol, serum total testosterone (TT), sex hormone-binding globulin, prostate-specific antigen, pituitary hormones levels were measured in serum. Standardized criteria (2009) were used to determine the prevalence of MetS. Patients were assessed based on the International Prostate Symptom Score (IPSS) and the IPSS-Quality of Life (IPSS-QoL) for LUTSs and the International Index of Erectile Function (IIEF) for ED. Hypogonadism was determined in accordance with the ISA, ISSAM, EAU, EAA and ASA recommendations. In men with MetS in the younger age group the incidence of ED was 2.4 times higher, and that of low TT level and hypogonadism was 8.4 times higher compared to men without the syndrome. In the older age group, an increased incidence of ED and low TT level in men with MetS compared to men without the syndrome was on the trend level, but the incidence of hypogonadism was for sure higher (by 1.6 times). In conclusion, the study showed that ED and hypogonadism are associated with MetS by a high degree of certainty in young men with LUTSs. In men of the older age group with LUTSs, the presence of MetS is not so clearly associated with ED and hypogonadism due to the fact that the incidence of these urogenital diseases is also high in men without MetS.展开更多

Despite its effectivene...Prostate cancer （PCa） is the most common visceral malignancy in men with androgen deprivation therapy （ADT） the preferred therapy to suppress testosterone production and hence tumor growth. Despite its effectiveness in lowering testosterone, ADT is associated with side effects including loss of muscle mass, diminished muscle strength, decrements in physical performance, earlier fatigue and declining quality of life. This review reports a survey of the literature with a focus on changes in muscle strength, physical function and body composition, due to short-term and long-term ADT. Studies in these areas are sparse, especially well-controlled, prospective randomized trials. Cross-sectional and longitudinal data （up to 2 years） for men with PCa treated with ADT as well as patients with PCa not receiving ADT and age-matched healthy men are presented when available. Based on limited longitudinal data, the adverse effects of ADT on muscle function, physical performance and body composition occur shortly after the onset of ADT and tend to persist and worsen over time. Exercise training is a safe and effective intervention for mitigating these changes and initial guidelines for exercise program design for men with PCa have been published by the American College of Sports Medicine. Disparities in study duration, types of studies and other patient-specific variables such as time since diagnosis, cancer stage and comorbidities may all affect an understanding of the influence of ADT on health, physical performance and mortality.展开更多
