Does HIV VCT Reduce Risk Behaviors? An Observational Study in Guatemala City
Bibliographic record
Abstract
OBJECTIVE: We examined the impact of HIV voluntary counseling and testing on self-reported behavioral risks three months after HIV testing. DESIGN: Cohort study comparing self-reported risk behaviors prior to and three months after HIV testing. SETTING: Clinica Familiar Luis Angel Garcia, an HIV specialty clinic located in a Guatemalan National Hospital. SUBJECTS, PARTICIPANTS: 144 people undergoing HIV testing were enrolled. 44 were HIV positive. 41 HIV positive and 49 HIV negative subjects returned for follow-up interviews. INTERVENTION: All subjects were tested and received voluntary counseling regarding HIV infection, transmission, prevention, and interpretation of HIV test results. MAIN OUTCOME MEASURE: The primary study outcome measure was change in self-reported risk behaviors three months after voluntary counseling and testing. RESULTS: Men were more likely than women to report a history of sexually transmitted diseases, more than 2 sexual partners, using alcohol with sex, and receiving money for sex; they were less likely to have a regular partner. 26% of men reported non-heterosexual orientation; no woman did. Alcohol was the primary drug of abuse in both men and women. At three month follow-up HIV positive subjects showed decreases in the average number of sexual partners, use of alcohol with sex, and episodes of unprotected sex. CONCLUSIONS: Voluntary counseling and testing resulted in changes in some self-reported risk behaviors, but only among HIV positive subjects. On nearly all measures men report riskier behavior than women. Alcohol is the most commonly used drug in this population and is often used with sex.

How this classification was reachedexpand
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.
