Independent predictors of metabolic syndrome in HIV-infected patients.

Metabolic syndrome (MetS) is associated with development of type 2 diabetes mellitus and increased risk for cardiovascular disease. However, a few studies have assessed its prevalence and risk factors among HIV patients from developing countries. The aim of this study was to identify independent risk factors for metabolic syndrome by the criteria of the American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI) among HIV-infected men and women. A cross-sectional study enrolled patients, aged 18 years or older, who sought to confirm the diagnosis or sought treatment in the outpatient service of a public health care center in southern Brazil. From June 2006 to December 2008, certified research assistants conducted interviews using standardized questionnaires and anthropometric measurements. Fasting blood sample was collected, use of highly active antiretroviral therapy (HAART) was ascertained, and MetS was characterized by AHA/NHLBI criteria. In the total, 1240 of 1295 HIV-infected patients were included. MetS prevalence was 24.7% and was similar among men and women. Among men, age, education, physical activity, body mass index (BMI), and HAART use were independently associated with MetS, while among women, there were associations with age, BMI, and use of protease inhibitors. In conclusion, high prevalence of MetS was detected in HIV-infected men and women. In both genders, age and BMI were directly and independently associated with MetS. The association between the use of HAART and MetS was confirmed among men but not among women.
