Body mass index variation over time and associated factors among HIV-positive adults on second-line ART in north-west Ethiopia: a retrospective follow-up study.


ABSTRACT: OBJECTIVES:This study aimed to assess the evolution of body mass index (BMI) of HIV-positive adults on second-line antiretroviral therapy (ART) over time and factors affecting it in north-west Ethiopia. DESIGN:An institution-based retrospective follow-up study was conducted using data extracted from 1016 patient cards from February 2008 to February 2016. SETTING:Eight referral hospitals from Amhara region, Ethiopia were included. PARTICIPANTS:HIV patients who started second-line ART. OUTCOME MEASURES:Change in BMI since starting second-line ART. RESULTS:Five hundred and thirty-eight (52.95%) participants were males and the median age of the participants was 33 years (IQR: 28; 39). The median follow-up time was 18 months (IQR: 5.2; 32.2). The average change of BMI showed linear increase over time. The amount of BMI increment or decrement according to each variable was shown as ? coefficients. Treatment duration (?=0.013, 95%?CI 0.004 to 0.022), isoniazid prophylaxis (?=0.87, 95%?CI 0.32 to 1.42), cotrimoxazole prophylaxis (?=0.63, 95%?CI 0.08 to 1.19), ambulatory functional status (?=-1.16, 95%?CI -1.95 to 1.31), bedridden functional status (?=-1.83, 95%?CI -2.47 to 1.21), WHO stage III (?=-0.42, 95%?CI -0.65 to 0.20), WHO stage IV (?=-0.62, 95%?CI -1.02 to 0.22), CD4 count (?=0.001, 95%?CI 0.0008 to 0.0015), and time interaction of variables like tertiary educational status (?=0.02, 95%?CI 0.01 to 0.04), ambulatory functional status (?=0.03, 95%?CI 0.01 to 0.05) and WHO stages III (?=0.01, 95%?CI 0.007 to 0.02) were found to be significant predictors. CONCLUSION:The BMI of patients has shown linear increment over the treatment time. Factors affecting it have been identified but its effect on cardiovascular disease needs further study.
