Abstract

Context: Benign prostatic hyperplasia poses a significant public health problem, but its etiology remains unclear. Obesity and associated abnormalities in glucose homeostasis may play a role in benign prostatic hyperplasia development by influencing prostate growth. Objective: The objective of this study was to determine whether obesity, fasting plasma glucose concentration, and diabetes are associated with radiologically determined prostate enlargement, an objective measure of benign prostatic hyperplasia. Design: This study was a cross-sectional analysis with robust variance estimates to account for multiple measures over time in the same individuals. Setting: This prospective cohort study was composed of community volunteers. Patients: Patients studied were 422 adult men enrolled in The Baltimore Longitudinal Study of Aging. Main Outcome Measurements: Total prostate volume as determined by pelvic magnetic resonance imaging was measured. Results: Among 422 participants, 91 (21.6%) had prostate enlargement (defined as total prostate volume ≥ 40 cc) at first visit. Compared with men of normal weight [body mass index (BMI) <25 kg/m 2], the age-adjusted odds ratio (OR) for prostate enlargement for overweight men (BMI, 25-29.9 kg/m2) was 1.41 (95% CI, 0.84-2.37), for obese men (BMI, 30-34 kg/m2) was 1.27 (95% CI, 0.68-2.39), and for severely obese men (BMI ≥ 35 kg/m2) was 3.52 (95% CI, 1.45-8.56) (P = 0.01). Men with elevated fasting glucose (>110 mg/dl) were more likely to have an enlarged prostate than men with normal fasting glucose (≤110 mg/dl) (OR, 2.98; 95% CI, 1.70-5.23), as were men with a diagnosis of diabetes (OR, 2.25; 95% CI, 1.23-4.11). Conclusions: Obesity, elevated fasting plasma glucose, and diabetes are risk factors for benign prostatic hyperplasia.
