【 摘 要 】

Abstract Background HIV and malaria are the leading causes of morbidity and mortality in the developing world including Ethiopia. Globally, HIV-malaria co-infection causes approximately 3 million deaths per year. However, both these infections are preventable if measures are taken on determinant factors. The objective of the study was therefore to assess factors associated with HIV-malaria co-infection among HIV-positive people who lived in Shewarobit district, northeast Ethiopia. Methods Unmatched case-control study was conducted among people living with HIV (PLWHA) in Shewarobit district from February 28, 2018, to April 30, 2018. The sample size was determined taking the assumption of 95% CI, 85% power, 3:1 control to case ratio, the proportion of PLWHA-malaria coinfection of 22.7%, OR 2.73, and 10% non-response rate. The final sample size was 262 (66 cases and 196 controls). Cases were adults on anti-retroviral therapy and diagnosed positive for malaria by microscopy while controls were adults on anti-retroviral therapy and diagnosed negative for malaria by microscopy in the previous 6 months before the survey. Result The median age of cases and controls in years was 35 (IQR = 19) and 38 (IQR = 19) respectively. Variables that had a significant association with HIV-malaria co-infection were non-in-door residual spraying (adjusted odds ratio (AOR) = 4.91; 95% CI 4.03, 15.13), poor perception on the health risk of HIV-malaria co-infections (AOR = 4.11; 95% CI 1.28, 10.17), non-use of insecticidal treated bed nets (AOR = 6.21; 95%CI 2.74, 14.11), non-use of cotrimoxazole prophylaxis (AOR = 2.42; 95% CI 1.11, 5.28), and not received health education on the risk of HIV-malaria interaction (AOR = 4.11; 95% CI 1.24, 4.84). Conclusion Provision of cotrimoxazole prophylaxis, sleeping under an insecticidal treated bed net, and indoor residual spraying help to reduce HIV-malaria co-infection-associated morbidity/mortality.
