Table 3.
Multivariable associations1 (adjusted odds ratios [AOR]) and 95% confidence intervals (95% CIs): multivariate associations between social, environmental and intervention exposure factors and condom use with non-commercial partners. Five models (MODEL1-MODEL5) were constructed for each of the five explanatory variables for intervention exposure and each of the two outcomes, for 10 models total.

1 Models were all adjusted for variables that were included a priori and variables that were significantly associated with each outcome on the p<0.10-level in bivariate analysis. For all three outcomes, a priori variables included district and typology of sex work (place of solicitation); for condom use with the husband or cohabiting partners, models were also adjusted by age at first sex work.
2 Consistent condom use is defined as reporting always (100%) using condoms.
/ Test for trend not significant in bivariate analysis, and was not tested in multivariable models.
