An omitted level: an examination of relational orientations and viral suppression among HIV serodiscordant male couples.

Couples' adopting a relational orientation, when partners regard themselves as a collective unit, is associated with optimal health. HIV-positive men and their HIV-negative partners (N = 116 serodiscordant male couples) were surveyed. Logistic regression showed greater relational orientations of HIV-positive [adjusted odds ratio (aOR) = 7.87; 95% confidence interval (CI): 1.63 to 38.05] and HIV-negative partners (aOR = 6.16; 95% CI: 1.43 to 26.59) and HIV-positive partners' higher income (aOR = 2.95; 95% CI: 1.13 to 7.70) and lower depression (aOR = 0.39; 95% CI: 0.15 to 0.97) were associated with viral suppression with no evidence of mediation by adherence. Incorporating relationship dynamics into biomedical strategies is a promising avenue for research and intervention.
