Serodiscordance predictors among couples in the HIV context: implications for health care

Abstract

Abstract Background After HIV diagnosis, people maintain, reestablish their sexual lives, or build new relationships, often with HIV seronegative partners. Therefore, understanding the factors concerning couple-vulnerability is essential in order to design effective HIV preventive strategies. We examined HIV serodiscordant couples prevalence and their associated factors from a Brazilian city. Methods This is a cross-sectional analytical study carried out with people living with HIV (PLHIV) who had an active sex life and were engagement in HIV health care follow-up. Data were collected using a semi-structured questionnaire during individual interviews. We analyzed data using bivariate and multiple logistic regression analyses. Results There was 72.0% of HIV serodiscordant partnerships. Those who inconsistently used condoms (aOR: 0.3[0.13–0.7]) and/or had HIV detectable viral load (aOR: 0.29 [0.12–0.7]) were less likely to have an HIV serodiscordant sexual partner. On other hand, the lack of HIV transmission counseling by the health service (aOR: 5.08 [2.02–12.76]), or those who had a casual partner (aOR: 8.12 [1.7–38.8]) or a steady and casual one concomitantly (aOR: 24.82 [1.46–420.83]), were more likely to indicate an HIV serodiscordant partnership. Conclusion The findings showed a high prevalence of serodiscordant partnerships in PLHIV. Greater visibility among couples in the health services is needed as well as a reassessment in order to provide PLHIV and their sexual partners with care strategies, by the health professionals.
