Title
Obesity and the risk of colonic diverticulosis: A meta-Analysis
Abstract
© The ASCRS 2018. BACKGROUND: The possible relationship between obesity and the risk of colonic diverticulosis has been suggested by recent epidemiologic studies, although the results were inconsistent. OBJECTIVE: This systematic review and meta-Analysis was conducted to summarize all of the available data. DATA SOURCES: A comprehensive literature review was conducted using the MEDLINE and EMBASE databases through January 2017. STUDY SELECTION: Studies that compared the risk of colonic diverticulosis among subjects with obesity versus those without obesity were included. MAIN OUTCOME MEASURES: Effect estimates from each study were extracted and combined together using a random-effect, generic inverse variance method. RESULTS: Of 2989 potentially eligible articles, 10 studies (9 cross-sectional studies and 1 prospective cohort study) with 53,520 participants met the eligibility criteria and were included in the meta-Analysis. The risk of colonic diverticulosis in obese subjects was significantly higher than in those without obesity, with a pooled OR of 1.41 (95% CI, 1.20-1.65). The statistical heterogeneity was high, with an I2 of 75%. LIMITATIONS: High statistical heterogeneity and publication bias in favor of positive studies may have been present in this meta-Analysis. CONCLUSIONS: A significant association between colonic diverticulosis and obesity was shown in this study. However, additional studies are still required to determine the causality.
