Abstract
BACKGROUND & AIMS
Much of what is known about the effects of alcohol and tobacco use on diverticular disease derives from studies of asymptomatic diverticulosis or complicated diverticulitis. We examined smoking and alcohol consumption and risk of incident diverticulitis in a large cohort of women.
METHODS
We conducted a prospective study of 84,232 women in the Nurses' Health Study II (NHS II) who were 39-52 years old and without known diverticulitis at baseline in 2003. Smoking was ascertained every 2 years and alcohol use every 4 years. We used Cox proportional hazards regression to estimate multivariable-adjusted hazards ratios (HRs) and 95% confidence intervals (CIs).
RESULTS
During 1,139,660 person-years of follow up, we identified 3018 incident cases of diverticulitis. After adjustment for other risk factors, current (HR, 1.20; 95% CI, 1.04-1.39) and past smoking (HR, 1.20; 95% CI, 1.11-1.30) were associated with increased risk of diverticulitis when compared with never smokers. Women who consumed ≥30 g/d of alcohol had a multivariate HR of 1.26 (95% CI, 1.05-1.50) when compared with women who did not drink. A joint analysis of smoking and alcohol found that individuals who ever smoked and consumed ≥15 g/d of alcohol were at highest risk of diverticulitis (multivariate HR, 1.60; 95% CI, 1.16-2.21), compared with participants who never smoked and reported no alcohol use.
CONCLUSIONS
In this large prospective study of women, smoking and alcohol consumption were associated with an increased risk of incident diverticulitis. These data highlight additional modifiable risk factors for diverticulitis that may aid in prevention.
