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(More)
