Magnitude and Factors Associated with Partner and Family-Based Index Case HIV Testing Among Clients on Anti-Retroviral Therapy Follow-ups at Holeta Health Centre, Oromia, Ethiopia

Background: Index clients are HIV-positive individuals at HIV Testing and Counselling Centres who were enrolled in treatment, care, and support services. Most of the index cases did not test hard-to-reach groups, including children and adult sexual partners. The aim of this study was to assess the magnitude and factors associated with partner and family-based index case HIV testing among HIV-positive clients who are on Anti-Retroviral Therapy and follow up at Holeta Health Centre, Ethiopia, 2022 G.C. Methods: A facility-based cross-sectional study was conducted on 316 selected individuals using simple random sampling techniques. The data was collected using structured questionnaires. The data were entered into EPI Info version 7.14 and then exported to SPSS version 24 for analysis. Bivariate logistic regression was used for each independent variable to check its association with the dependent variable. All variables with a P-value <0.25 in bivariate analysis were entered into a multivariate logistic regression analysis to identify factors independently associated with the dependent variables with a P value <0.05 were considered statistically significant factors and an adjusted odds ratio with a 95% confidence interval was used to measure the strength of the association. Result: This study showed that among the study participants, 86.8% had tested a partner and 92.9% had tested at least one child. Marital Status (AOR = 0.06 CI: 0.02-0.21), duration on ART (AOR = 2.71 CI: 1.17–6.25), and disclosure status (AOR = 4.26 CI: 1.21–15.05) were identified to be significantly associated with partner- and family-based index case HIV testing. Conclusion: This study showed that most of the study participants had tested with a partner and at least one child. Partner and family-based index case HIV testing has a significant association with marital status, duration on ART, and disclosure status of index cases.
