[Alcohol consumption and incidence of abdominal obesity in participants of the ELSA-Brasil cohort after nine years of follow-up].

The scope of this article is to analyze the correlation between alcohol consumption and abdominal obesity in participants of the ELSA-Brasil cohort after a follow-up period of nine years. A longitudinal analysis was performed with baseline and follow-up data from ELSA-Brasil. At baseline, 15,105 civil servants were enrolled. After exclusions, the final sample consisted of 3,591 participants. Anthropometric and lifestyle data were collected, and abdominal obesity was diagnosed in accordance with the World Health Organization parameters. The t-test and chi-square test were applied, and crude and adjusted Poisson models were assessed. The results revealed that more than 70% of the sample reported alcohol use. In nine years, an increase in abdominal obesity and alcohol consumption was observed among men and women. A total of 1,588 new cases of abdominal obesity were identified. Higher alcohol consumption increased the risk of abdominal obesity in men (1.15, 95%CI 1.01-1.31, p < 0.001). The conclusion drawn was that after a follow-up period of 9 years, the highest risk of abdominal obesity was observed only in men who increased their alcohol consumption.
