Alcohol consumption and risk of type 2 diabetes in European men and women: influence of beverage type and body size. The EPIC–InterAct study. J Intern Med 2012; 272: 358–370.Objective:  To investigate the association between alcohol consumption and type 2 diabetes, and determine whether this is modified by sex, body mass index (BMI) and beverage type.Design:  Multicentre prospective case–cohort study.Setting:  Eight countries from the European Prospective Investigation into Cancer and Nutrition cohort.Subjects:  A representative baseline sample of 16 154 participants and 12 403 incident cases of type 2 diabetes.Interventions:  Alcohol consumption assessed using validated dietary questionnaires.Main outcome measures:  Occurrence of type 2 diabetes based on multiple sources (mainly self‐reports), verified against medical information.Results:  Amongst men, moderate alcohol consumption was nonsignificantly associated with a lower incidence of diabetes with a hazard ratio (HR) of 0.90 (95% CI: 0.78–1.05) for 6.1–12.0 versus 0.1–6.0 g day−1, adjusted for dietary and diabetes risk factors. However, the lowest risk was observed at higher intakes of 24.1–96.0 g day−1 with an HR of 0.86 (95% CI: 0.75–0.98). Amongst women, moderate alcohol consumption was associated with a lower incidence of diabetes with a hazard ratio of 0.82 (95% CI: 0.72–0.92) for 6.1–12.0 g day−1 (P interaction gender <0.01). The inverse association between alcohol consumption and diabetes was more pronounced amongst overweight (BMI ≥ 25 kg m−2) than normal‐weight men and women (P interaction < 0.05). Adjusting for waist and hip circumference did not alter the results for men, but attenuated the association for women (HR=0.90, 95% CI: 0.79–1.03 for 6.1–12.0 g day−1). Wine consumption for men and fortified wine consumption for women were most strongly associated with a reduced risk of diabetes.Conclusions:  The results of this study show that moderate alcohol consumption is associated with a lower risk of type 2 diabetes amongst women only. However, this risk reduction is in part explained by fat distribution. The relation between alcohol consumption and type 2 diabetes was stronger for overweight than normal‐weight women and men.
