Abstract

Background and Aim: In East Asia, colonic diverticulosis develops most commonly in the right colon and is known to have different characteristics compared with left-sided one. This study was designed to investigate whether right-colonic diverticulosis is associated with posteriori dietary patterns. Methods: We retrospectively reviewed medical records of prospectively collected cohort that received health check-up in Korea between May 2011 and January 2012. Their anthropometric data, biochemical results, medication history, underlying diseases, colonoscopic findings, and dietary data obtained from semi-quantitative food-frequency questionnaire were analyzed. Three dietary patterns were identified using factor analysis: healthy dietary pattern (vegetables, fish, seaweed, fruits, and beans), meat dietary pattern (red meat, processed meat/fish, fried noodle, poultry, and cephalopods), and snack dietary pattern (bread, sweets, dairy products, nuts, and rice cake). Results: Out of the total 1911 patients, 203 (10.6%) had right-colonic diverticulosis, 21 (1.1%) had pan-colonic diverticulosis, and 12 (0.6%) had left-colonic diverticulosis. Among the total, none of the three patterns were associated with right-colonic diverticulosis, under adjustment with age, gender, body mass index, metabolic syndrome, and total energy intake. However, among women, meat dietary pattern was positively associated with right-colonic diverticulosis (odds ratio 1.866, 95% confidence interval: 1.0983–3.173, P = 0.021). Conclusion: This study demonstrated that meat dietary pattern is positively associated with right-colonic diverticulosis among women.
