- Context: Most previous prospective studies suggest that low serum IGF-1 associates with increased risk of cardiovascular disease (CVD) events whereas other studies suggest that high serum IGF-1 associates with increased risk of CVD events. Objective: We tested the hypothesis that not only low, but also high serum IGF-1 levels associate with increased risk of CVD events in elderly men. Setting and Design: Serum IGF-1 levels were measured in 2901 elderly men (age 69-81 years) included in the Swedish cohort of the prospective, population-based Osteoporotic Fractures in Men Study (MrOS), Sweden cohort. Data for CVD events were obtained from national Swedish registers with no loss of followup. Results: During followup (median, 5.1 y) 589 participants experienced a CVD event. The association between serum IGF-1 and risk of CVD events was nonlinear, and restricted cubic spline Cox regression analysis revealed a U-shaped association between serum IGF-1 levels and CVD events (P < .01 for nonlinearity). Low as well as high serum IGF-1 (quintile 1 or 5 vs quintiles 2-4) significantly associated with increased risk for CVD events (hazard ratio [HR] = 1.25, 95% confidence interval, [CI], 1.02-1.54; and HR = 1.35, 95% CI 1.10-1.66, respectively). These associations remained after adjustment for prevalent CVD and multiple risk factors. High serum IGF-1 associated with increased risk of coronary heart disease (CHD) events but not with risk of cerebrovascular events. Conclusions: Both low and high serum IGF-1 levels are risk markers for CVD events in elderly men. The association between high serum IGF-1 and CVD events is mainly driven by CHD events.

- Purpose: We tested the hypothesis that low vitamin D is associated with benign prostatic hyperplasia. We also studied whether body composition, sex hormones, serum sex hormone-binding globulin, albumin corrected serum calcium, adiponectin and lipid status are associated with benign prostatic hyperplasia. Materials and Methods: We investigated 184 representative, randomly selected men 72 to 76 years old enrolled in the Gothenburg arm of the Osteoporotic Fractures in Men Study (MrOS). Men with a history of prostate cancer, prostate operation or medication for benign prostatic hyperplasia were excluded from study, leaving 155 available for analysis. A cross-sectional study was performed in which benign prostatic hyperplasia measured by total prostate volume was related to clinical, anthropometric, endocrine and metabolic factors on univariate and multivariate analyses with regression models. Results: Median prostate volume was 40 ml. In multivariate models only 25-OH vitamin D, albumin corrected serum calcium, serum sex hormone-binding globulin and high density lipoprotein cholesterol were significantly and inversely associated with large prostate glands. Conclusions: The current report adds 4 independent factors associated with benign prostatic hyperplasia, including low 25-OH vitamin D, serum calcium, sex hormone-binding globulin and high density lipoprotein cholesterol.
