OBJECTIVE: The relation of anthropometric measures, diabetes, hypertension and hyperlipidemia with benign prostatic hyperplasia (BPH) risk was investigated. DESIGN: Hospital-based case-control study. SUBJECTS: Cases were 1369 men with histologically confirmed BPH, and controls were 1451 men below 75y, admitted to hospital for acute non-neoplastic diseases. MEASUREMENTS: Using a structured questionnaire, trained interviewers collected information on self-reported height and weight, and measured waist and hip circumference of patients. The odds ratios (OR) and 95% confidence intervals (CI) were estimated using unconditional multiple logistic regression models. RESULTS: Compared to the corresponding lowest quartile, the OR for the highest one were 0.76 ( 95% CI 0.59 - 0.98) for body weight, 0.71 ( 95% CI 0.54 - 0.94) for waist- to- hip ratio and 0.87 ( 95% CI 0.70 - 1.09) for body mass index (BMI, kg/ m(2)). Compared to a lowest lifelong BMI < 20.7 kg/ m(2), the OR was 1.56 ( 95% CI 1.25 - 1.95) for a lowest lifelong BMI >= 23.7 kg/ m(2). The OR was 0.74 ( 95% CI 0.60 - 0.93) for a lifelong increase of BMI >= 6.1 kg/ m(2), compared to < 1.6 kg/ m(2). No association emerged for history of diabetes, hypertension and hyperlipidemia. CONCLUSIONS: Overweight was modestly, inversely related to BPH. The hypothesis of reduced testosterone levels in obese individuals may explain the different BPH risk and need to be tested.

MEASUREMENTS: Using a structured questionnaire, trained interviewers collected information on self-reported height and weight, and measured waist and hip circumference of patients. The odds ratios (OR) and 95% confidence intervals (CI) were estimated using unconditional multiple logistic regression models.
