Abstract
BACKGROUND: Globally, anemia is a common hematological disorder among HIV-infected patients. People with anemia often suffer from impaired physical functioning, psychological distress, and poor quality of life. Therefore, the aim of this study was to determine the incidence of anemia and its determinants among HIV positive individuals in northwest Ethiopia. METHODS: A total of 486 adult HIV positive patients on the first-line ART with complete information were enrolled in the adult care clinics of northwest Amhara referral hospitals from December 2015 to December 2018. EpiData version 4.2 was used for data entry and Stata version 14 for analysis. Variables having time to event nature were presented with the Kaplan-Meier function. The Cox regression model was used to identify predictors of anemia. Variables with P-values less than 0.2 in the bivariable analysis were considered in the multivariable regression. Adjusted hazard ratio with 95% CI was computed, and variables with less than 0.05 P-values in the multivariable Cox regression were taken as significant predictors of anemia. RESULTS: This study noted an overall 26.4 per 100 person-year observations (95% CI: 23.46, 30.74) incidence rate of anemia. According to the multivariable Cox regression, TB co-infection (AHR =1.99, 95% CI: 1.45, 2.74), zidovudine-based regimen (AHR=1.39, 95CI: 1.1, 1.85), CD4 level (AHR= 1.7, 95% CI: 1.23, 2.35), advanced WHO stage (AHR=1.32, 95% CI: 1.01, 1.74), and being underweight (AHR= 1.53, 95% CI: 1.14, 2.07) were predictors of anemia. CONCLUSION: Anemia is a burden among HIV patients in the study setting. Baseline clinical variables, TB co-infection, and zidovudine-based were predictors of anemia. Therefore, early identification of anemia and addressing significant predictors are highly suggested to the study setting.
