Factors independently associated with HIV/STIs among 212 female sex workers and their 212 non-commercial male partners in two Mexico-USA border cities (N = 424)
| Variable | HIV/STI positivity: marginal effects (robust SE)a | |
|---|---|---|
| Women | Men | |
| FSW had regular clients, past month | −0.11** (0.06) | −0.09** (0.04) |
| Sexual relationship decision-making power score (per point increase)b | −0.02** (0.01) | 0.00 (0.00) |

aMarginal effects (shown with robust standard errors) represent the change in probability of having positive test result(s) for HIV/STIs associated with a 1-unit change in each independent variable; model controls for couple-specific effects
bSexual relationship power subscales
cConflict subscales (combined) for perpetrating or being the victim of psychological aggression, physical assault, injury, and sexual coercion within relationships
