The relationship between alcohol consumption and metabolic syndrome remains controversial. A study investigated the relationship between alcohol consumption and metabolic syndrome components and prevalence. 10,037 subjects (3,076 metabolic syndrome and 6,961 non-metabolic syndrome) were analysed in a community-based cohort. Subjects were categorsed according to their alcohol consumption; non-drinker, very light (0.1-5.0 g/day), light (5.1-15.0 g/day), moderate (15.1-30.0 g/day), and heavy drinker (>30 g/day) and multiple logistic regression models were performed to estimate odds ratios (ORs) and confidence intervals (CIs).
The prevalence of metabolic syndrome in both males and females was associated with alcohol drinking status (p<0.0001). Very light alcohol consumption (0.1-5.0 g/day) was significantly associated with lower prevalence of metabolic syndrome in both genders compared to non-drinkers. Heavy drinking (>30.0 g/day) did not show a significant association with prevalence of metabolic syndrome. It did, however, show an association with glucose and HDL cholesterol.
The authors conclude that their results indicate that alcohol drinking (0.1-5.0 g/day) contributed to decrease prevalence of MetS and components, including triglyceride and HDL cholesterol.
