Antiretroviral therapy and sexual behavior in Uganda: a cohort study
Bibliographic record
Abstract
OBJECTIVE: To assess evidence for sexual behavior change in response to antiretroviral therapy (ART) among members of a Ugandan clinical cohort. Secondarily, to examine factors associated with both sexual behavior and ART independently, that may help to assess the impact that ART is likely to have on the HIV epidemic. DESIGN: Retrospective analysis of data from an open cohort. METHODS: ART roll-out began in the cohort in 2004. Using 3-monthly data from 2002 to 2009, we conducted regression and descriptive analyses to examine associations between timing of ART initiation and sexual behavior among HIV-infected, and timing of ART availability and sexual behavior among HIV-uninfected. We also examined partner turnover rates, and the proportion of HIV-infected on ART - two important factors for modeling the potential impact of ART on the HIV epidemic. RESULTS: Risky sexual behavior among HIV-infected people rose on several indicators after ART initiation, but not to levels higher than two or more years before initiation. Some evidence suggests that the availability of ART may impact risky behavior among HIV-uninfected people, although this was inconsistent across different reported behavior variables. CONCLUSION: The HIV-uninfected is larger than the HIV-infected population. If risky behavior among this population increases due to the feeling of safety that ART provides, this will affect the impact of ART on the HIV epidemic. Policy makers are urged to intensify messages associating sexual behavior and HIV and to target both HIV-infected and uninfected people.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
