Timing and Type of Alcohol Consumption and the Metabolic Syndrome - ELSA-Brasil.
2016
The prevalence of the
metabolic syndromeis rising worldwide. Its association with alcohol intake, a major lifestyle factor, is unclear, particularly with respect to the influence of drinking with as opposed to outside of
meals. We investigated the associations of different aspects of alcohol consumption with the
metabolic syndromeand its components. In cross-sectional analyses of 14,375 active or retired civil servants (aged 35–74 years) participating in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), we fitted logistic regression models to investigate interactions between the quantity of alcohol, the timing of its consumption with respect to
meals, and the predominant beverage type in the association of alcohol consumption with the
metabolic syndrome. In analyses adjusted for age, sex, educational level, income, socioeconomic status, ethnicity, smoking, body mass index, and physical activity, light consumption of alcoholic beverages with
mealswas inversely associated with the
metabolic syndrome(≤4 drinks/week: OR = 0.85, 95%CI 0.74–0.97; 4 to 7 drinks/week: OR = 0.75, 95%CI 0.61–0.92), compared to abstention/occasional drinking. On the other hand, greater consumption of alcohol consumed outside of
mealswas significantly associated with the
metabolic syndrome(7 to 14 drinks/week: OR = 1.32, 95%CI 1.11–1.57; ≥14 drinks/week: OR = 1.60, 95%CI 1.29–1.98). Drinking predominantly wine, which occurred mostly with
meals, was significantly related to a lower syndrome prevalence; drinking predominantly beer, most notably when outside of
mealsand in larger quantity, was frequently associated with a greater prevalence. In conclusion, the alcohol—
metabolic syndromeassociation differs markedly depending on the relationship of intake to
meals. Beverage preference—wine or beer—appears to underlie at least part of this difference. Notably, most alcohol was consumed in metabolically unfavorable type and timing. If further investigations extend these findings to clinically relevant endpoints, public policies should recommend that alcohol, when taken, should be preferably consumed with
meals.
