Among individuals infected with HIV, highly active antiretroviral therapy has reduced the incidence of morbidity and mortality however, despite recent improvements in newer antiretrovirals patients continue to exhibit secondary effects related to body composition such as lipoatrophy of the periphery, increased adiposity of the trunk and lipomatosis, especially of the dorsocervical spine. Changes in body composition have been reported in 40-50% of HIV-infected patients. Several studies have shown that antiretroviral therapy contributes to changes in body composition and is coupled with increased dyslipidemia, insulin resistance and diabetes.
