Abstract

OBJECTIVES::

Data from generalised epidemic settings have consistently found that patients on ART reduce sexual risk behaviours, but how sexual behaviour changes in the general population in response to ART availability, including amongst HIV-uninfected and undiagnosed adults, has not been characterised in these settings.

DESIGN::

General population open cohort METHODS:: We report trends in sexual behaviour indicators for men aged 17-54 and women aged 17-49 in rural KwaZulu-Natal province based on annual sexual behaviour surveys during ART scale-up from 2005-2011. Estimates are adjusted for survey non-participation and non-response to individual survey items using inverse probability weighting and multiple imputation. Trends are presented by HIV status, knowledge of status, age, and marital status.

RESULTS::

Reports of condom use at last sex with a regular partner increased by 2.6 percentage points per year (95% CI 1.5%, 3.7%) for men and 4.1% per year (3.0%, 5.3%) for women. Condom use at last sex with a casual partner was high and did not change significantly over the period for both sexes. There were statistically significant declines in the percentage reporting multiple partnerships in the last year and the point prevalence of concurrency. Trends within subgroups are generally consistent with overall estimates.

CONCLUSION::

We find no evidence of increased sexual risk-taking following ART availability and protective changes in some behaviours, suggesting that general trends in sexual behaviour are not counter-acting preventive effects of HIV treatment. Continued monitoring of population-level sexual behaviour indicators will be essential to interpreting the success of combination prevention programmes.
