Bottom Line: Among those testing positive, this risk reduction was enhanced with time since testing.Among men, no behavioural risk reduction associated with VCT was observed.This study suggests that, among women, particularly those who are infected, behavioural risk reduction does occur following VCT.

ABSTRACT
Voluntary counselling and testing (VCT) is promoted as a potential HIV prevention measure. We describe trends in uptake of VCT for HIV, and patterns of subsequent behaviour change associated with receiving VCT in a population-based open cohort in Manicaland, Zimbabwe. The relationship between receipt of VCT and subsequent reported behaviour was analysed using generalized linear models with random effects. At the third survey, 8.6% of participants (1,079/12,533), had previously received VCT. Women who received VCT, both those positive and negative, reduced their reported number of new partners. Among those testing positive, this risk reduction was enhanced with time since testing. Among men, no behavioural risk reduction associated with VCT was observed. Significant increases in consistent condom use, with regular or non-regular partners, following VCT, were not observed. This study suggests that, among women, particularly those who are infected, behavioural risk reduction does occur following VCT.

Relative change in the number of new partners in the last year, following VCT. The results in the above figure are based on comparing those who received VCT to those who did not receive VCT. Thus, this figure illustrates the additional reduction in mean number of new partners in the last year associated with receiving VCT. The 0% indicates no change. Results are adjusted for age (5 year categories), calendar year and marital status. The relative change is calculated as: Exp(Coef.) − 1

Mentions: Against a background of considerable declines in risk behaviour, including reductions in casual sex, [25], no significant additional behavioural risk reduction associated with VCT was observed among either HIV positive or negative men (Table 3). Women who received VCT reduced their number of new sexual partners in the last year more than those who did not test (Table 3; Fig. 2). This was true regardless of HIV status, but greater additional reductions were observed among those receiving a positive test result. Women receiving a positive result also reduced their bar attendance in the last month more than those not testing. Men testing positive and women testing negative tended to report more visits to beer halls in the last month. Overall, levels of consistent condom use increased among men and women testing positive; however, these were not significant changes (Table 3).Table 3
