We observed 341 incident cases of MS. Consumers of ¿7 drinks/wk presented a significantly higher risk of developing MS (aOR: 1.80; 95% CI: 1.22-2.66; p < 0.001) compared with non-drinkers. In addition, alcohol drinkers (¿7 drinks/wk) had higher risk of hypertriglyceridemia (aOR: 2.07; 95% CI: 1.46-2.93) and impaired fasting glucose (aOR: 1.54; 95% CI: 1.16-2.04). Beer consumption was associated with higher risk for MS (p for trend = 0.027) and higher risk of hypertriglyceridemia (aOR: 1.81; 95% CI: 1.02-3.20), but with lower risk of low HDL-cholesterol criterion (aOR: 0.21; 95% CI: 0.05-0.89) for ¿7 drinks/wk versus no consumption. Non-significant association was observed between wine or liquor consumption and MS.
Consumption of at least seven alcoholic drinks per week was associated with a higher risk of developing MS among subjects initially free of any MS criteria.
