RESEARCH DESIGN AND METHODS - The 15 original prospective cohort studies that were included comprise 11,959 incident cases of type 2 diabetes in 369,862 individuals who, on average, were followed for 12 years. RESULTS - After pooling the data, a U-shaped relationship was found. Compared with nonconsumers, the relative risk (RR) for type 2 diabetes in those who consumed ≤6 g/day alcohol was 0.87 (95% CI 0.79-0.95). For the moderate consumption ranges of 6-12, 12-24, and 24-48 g/day, RRs of 0.70 (0.61-0.79), 0.69 (0.58-0.81), and 0.72 (0.62-0.84) were found, respectively. The risk of type 2 diabetes in heavy drinkers (≥48 g/day) was equal to that in nonconsumers (1.04 [0.84-1.29]). In general, nonsignificant trends for larger RR reduction associated with moderate alcohol consumption were observed for women compared with men, for crude compared with multivariate-adjusted analyses, and for studies that used self-reports instead of testing for type 2 diabetes definition. No differences in RR reductions were found between individuals with low or high BMI. CONCLUSIONS - The present evidence from observational studies suggests an ∼30% reduced risk of type 2 diabetes in moderate alcohol consumers, whereas no risk reduction is observed in consumers of ≥48 g/day. © 2005 by the American Diabetes Association.
