This study assessed how well body mass index (BMI: kg/m2) correlated with survival among HIV infected patients with and without TB co-infection. Methods We retrospectively evaluated clinical data from 1000 HIV infected patients, among whom 389 were also co-infected with TB, between January 2008 and December 2010, in KwaZulu-Natal, South Africa. Results Among 948 patients eligible for analysis, 15.7% (149/948) were underweight (< 18.50), 55.9% (530/948) had normal BMI (≥18.50–24.90), 18.7% (177/948) were overweight (25.00–29.00) and 9.7% (92/948) were obese (≥30.00). Irrespective of TB status, underweight patients, had significantly higher risk of death compared to those with normal BMI at baseline (aHR = 2.9; 95% CI: 1.5–5.7; P = 0.002). Conclusions Irrespective of TB co-infection, low BMI correlated with mortality in HIV infected patients.enAttribution 3.0 United Stateshttp://creativecommons.org/licenses/by/3.0/us/Body mass indexHIV infected patientsTB co-infectionSDG-03 Good health and well-beingArticleInfectious Diseases of Poverty
