Type 2 diabetes is common in industrial countries and is a major cause of cardiovascular disease and all-cause mortality. The study by Wei M et al and published by Diabetes Care, vol 23, No1, included 8,633 men with fasting plasma glucose measurements from at least two medical examinations. Alcohol intake was classified into 5 groups: non -drinkers and 4 quartiles (Qs) of drinkers according to the amount of alcohol intake. Type 2 diabetes was diagnosed by 1997 American Diabetes Association criteria.

Results: There was a U-shaped association between alcohol intake and diabetes with the lowest incidence of diabetes at Q2. Men in Q3 and Q4 had a 2.2 - 2.4 fold risk of developing diabetes, while non-drinkers and men in Q1 had 1.8 - fold and 1.4- fold higher risk of diabetes, respectively. After adjustments for age, fasting plasma glucose, smoking, BMI, blood pressure, serum triglyceride concentration, cardiorespiratory fitness, HDL cholesterol, waist circumference and parental diabetes these associations persisted.

An elevated risk of developing type 2 diabetes was observed in non-drinkers and men with high alcohol intakes, when compared with men who reported moderate alcohol intake. The risk of developing type 2 diabetes in men with a high alcohol intake may be reduced if they drink less.
