Prevalência de esteatose hepática e consumo de álcool em participantes do Projeto Atividade Física na Vila

Abstract

Screening image studies have shown that the frequency of hepatic steatosis findings has been progressivly increasing. The risk of developing NAFLD has been described and associated with obesity, insulin resistance and metabolic syndrome. There seems to be a correlation between NAFLD, alcohol e hepatic fibrosis. Our objective was to describe the prevalence of NAFLD and alcoholism in the participants of the of the Physical Activity in Community Project and to evaluate the associations between hepatic steatosis and presence of obesity and visceral obesity. Abdominal ultrasound was performed in 69 patients, 53.02±1.26 years old, looking for the presence and for the degree of fatty liver as well as subcutaneous and visceral fat. Patients with viral hepatitis and significant alcoholism were excluded after the AUDIT test. After this analysis, 60 patients were evaluated according to their anthropometrics data and were allocated into two groups: with and without fatty liver disease. The prevalence of alcoholism was 8.7%. Thirty seven percent of the patients showed up with NAFLD and were considered low to moderate risk (91%). The NAFLD showed a significant rise in the body mass index (34.1±8.7 versus 29.8±6.5kg/m2), waist circumference (102,6±12,7 versus 95.3±12.3cm), overall weight, (85,8±18,7 versus 74,5± 17.7kg), and visceral fat (47.9±10.5 versus 36.0±12.7mm). Hepatic steatosis is common in obese, especially in those with visceral obesity. We know that alcohol and visceral obesity are involved in the physiopathologic process of hepatic steatosis. For this reason, patients with Hepatic steatosis and excessive alcohol consumption may be at greater risk for Cirrhossis and hepatic insufficiency.
