Association between alcohol, impulsivity, and number of sexual partners

Number of sexual partners	Unadjusted model IRR (95% CI)	Primary adjusted model aIRR (95% CI)
Overall sample, n = 241	n = 241	n = 229
Hazardous drinking	0.54 (0.45–0.65)*	0.64 (0.52–0.79)*
Impulsivity—continuous	0.97 (0.96–0.98)*	0.95 (0.94–0.96)*
Gender, female		1.39 (1.11–1.74)*
Married or partnered, yes		0.90 (0.71–1.14)
CD4 cell count, 0–350		1.05 (0.84–1.31)
Received money/drugs for sex, past 6 months, yes		11.73 (9.00–15.29)*
Used cannabis, past 6 months, yes		0.56 (0.43–0.72)*
Used other drugs, past 6 months, yes		1.87 (1.45–2.41)*
Age		1.01 (0.99–1.04)

This primary regression model adjusts for gender, marital status, CD4 count <350, receipt of recent sex trade, cannabis use, and other drug use. A number of sexual partners were modeled using negative binomial regression. Hazardous drinking refers to hazardous drinking as measured an AUDIT score of 8 or more. Impulsivity was modeled as a continuous variable. Covariate reference groups: gender = female; married or partnered = yes; CD4 cell count = 0–350; received money/drugs for sex, past 6 months = yes; used cannabis, past 6 months = yes; used other drugs, past 6 months = yes.

aIRR = adjusted incidence rate ratio; CI = confidence interval; IRR = incidence rate ratio.
