Changes in Alcohol Consumption and Subsequent Risk of Type 2 Diabetes in Men

Summary

Objective -The objective of this study was to investigate the association of four-year changes in alcohol consumption with subsequent risk of type 2 diabetes. Research Design and Methods - We prospectively examined 38,031 men from the Health Professionals Follow-up Study free of diagnosed diabetes or cancer in 1990. Alcohol consumption was reported on food frequency questionnaires and updated every four years. Results - A total of 1905 cases of type 2 diabetes occurred during 428,497 person-years of follow-up. A 7.5 g/day (~half a glass) increase in alcohol consumption over four years was associated with lower diabetes risk among initial nondrinkers (multivariable hazard ratio [HR] 0.78; 95% confidence interval [CI] 0.60-1.00) and drinkers initially consuming
