Table 2.

Multivariable associations¹ (adjusted odds ratios [AOR]) and 95% confidence intervals (95% CIs): multivariable associations between social, environmental and intervention exposure factors and consistent condom use with commercial sex clients. Five models (MODEL1-MODEL5) were constructed for each of the five explanatory variables for intervention exposure and each outcome, for 15 models total.

MODEL1		OUTCOME: Consistent condom2 use within different sexual partnerships
		Condoms used in each occasion of sexual intercourse with clients in the most recent day worked		Consistent condom use with occasional clients		Consistent condom use with most recent repeat client

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 of condom use, a priori variables included typology of sex work (place of solicitation) and district; for condoms used in each occasion of sexual intercourse with clients in the most recent day worked, models were also adjusted by marital status, age and age at first sex; for condom use with occasional clients, models were also adjusted by age, marital status, literacy, age at first sex work; for condom use with most recent repeat client, models were also adjusted by education.

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.
