Abstract

Background:Adherence to the Mediterranean diet (MD) is associated with a reduced risk of several cancers. However, studies conducted in Mediterranean regions are scanty.Methods:To investigate the relation between MD and colorectal cancer risk in Italy, we pooled data from three case–control studies, including a total of 3745 colorectal cancer cases and 6804 hospital controls. Adherence to the MD was assessed using an a priori Mediterranean Diet Score (MDS), based on nine components.Results:Compared with the lowest adherence to the MD (0–2 MDS), the odds ratio (OR) was 0.52 (95% confidence interval (CI) 0.43–0.62) for the highest adherence (7–9 MDS), with a significant inverse trend in risk (P<0.0001). The OR for a 1-point increment in the MDS was 0.89 (95% CI 0.86–0.91). The inverse association was consistent across studies, cancer anatomical subsites and strata of selected covariates.Conclusions:This Italian study confirms a favourable role of MD on colorectal cancer risk.British Journal of Cancer advance online publication, 18 August 2016; doi:10.1038/bjc.2016.245 www.bjcancer.com.
