Predictors of HIV Serodiscordance among Couples in Southwestern Ethiopia

摘要

Background: With transmission of HIV occurring mainly through heterosexual contact, it is paramount to identify serodiscordant couples and implement preventive strategies that will protect the negative partner. The burden of serodiscordance and its predictors in Ethiopia is not clearly understood due to the dearth of data. Objective: To assess the prevalence and predictors of HIV serodiscordance among couples tested in Jimma University Specialized Hospital (JUSH) Voluntary Counseling and Testing (VCT) center. Methods: The study employed a case-control study design conducted at VCT center of JUSH in all registered serodiscordant couples and seroconcordant couples that were selected from the registered clients in the period from 2003 to 2010. A pretested structured questionnaire was used for data collection using medical chart ^w>ion. Data were entered, cleaned, and coded using Statistical Package of Social Sciences (SPSS) version 16. Results: The prevalence of serodiscordance in the study population was found to be 8.4%. Male and female discordants accounted for 5.8% (137) and 2.6% (62), respectively. Rare use of condom (adjusted odds ratio [AOR] = 7.2; 95% confidence interval [Cl] = 1.59-32.54) and active tuberculosis (TB) at enrollment (AOR= 17.7; 95% Cl = 2.3-139.2) were significantly found to be the predictors of serodiscordance. Conclusion: The prevalence of serodiscordance in the study area was found to be low, but it contributes to a clinically significant population that mandates implementation of preventive strategy. Sero-positive individuals who use condoms rarely should be encouraged to have their partners tested, and the association between active TB and serodiscordance underscores the need for further study.
