OBJECTIVES: Little is known about the effect of physical activity on diverticular complications. This study prospectively examined the associations between physical activity and diverticular bleeding and diverticulitis. METHODS: We studied 47,228 US males in the Health Professionals Follow-up Study cohort who were aged 40-75 years and free of diverticular disease, gastrointestinal cancer, and inflammatory bowel disease at baseline in 1986. Men reporting newly diagnosed diverticular disease on biennial follow-up questionnaires were sent supplemental questionnaires outlining details of diagnosis and treatment. Physical activity was assessed every 2 years. Men recorded the average time per week spent in eight recreational activities, and flights of stairs climbed per day. Cox proportional hazards regression was used to calculate relative risks (RRs). RESULTS: During 18 years of follow-up, 800 cases of diverticulitis and 383 cases of diverticular bleeding were identified. Total cumulative physical activity was associated with a decreased risk of diverticulitis and diverticular bleeding. After adjustment for potential confounders, the RR for men in the highest quintile of total activity (>or = 57.4 metabolic equivalent hours per week (MET-h/week) was 0.75 (95% confidence interval, CI, 0.58-0.95) for diverticulitis and 0.54 (95% CI, 0.38-0.77) for bleeding, as compared with men in the lowest quintile (
