Alcohol consumption is associated with DXA measurement of adiposity: the Pró-Saúde Study, Brazil.

Purpose: Evaluate the association between alcohol consumption and body adiposity. Methods: We analyzed cross-sectional data from a longitudinal investigation (Pró-Saúde Study), comprising a sample of 514 civil servants of both sexes (35-64 years). Daily alcohol consumption (wine, beer, and other alcoholic drinks) over the previous 6 months was assessed via food frequency questionnaire and categorized as no doses, up to 1 dose, and ≥1 dose. The total body mass, total fat mass (TFM), android fat mass (AFM), and gynoid fat mass (GFM) were measured via dual-energy X-ray absorptiometry. AFM (AFM%) and GFM (GFM%) were expressed as percentages relative to TFM. The ratio of AFM% and GFM% was calculated. Multiple linear regression analyses were performed after adjusting for age, calories not originating from alcohol, leisure-time physical activity and education. Results: Among nondrinkers, 59 % were women, and the age range between 45 and 54 years was predominant (44.3 %); 63.7 % of the nondrinkers were overweight/obese. Among drinkers of 1 dose or more/day, 67 % were males aged between 45 and 54 years (43.7 %); 69.1 % were overweight/obese. Among men, the daily consumption of ≥1 alcohol dose (13 g) was associated with an approximately 2 % ( β = 2.2, IC = 0.077; 4.303) adjusted for age, calories not originated from alcohol, leisure-time physical activity and education, increase in TFM, compared to those who reported no alcohol consumption during the previous 6 months. This association was not observed among women. In both sexes, no associations were observed between alcohol consumption and the other evaluated parameters of adiposity. Conclusion: Among men only, daily consumption of ≥1 alcohol dose was associated with increased adiposity, despite the relatively low average alcohol consumption in this study population.
