  1. Community-Level Secondary (Behavioral) Outcomes of NIMH Project Accept (HPTN 043) David D Celentano for the Project Accept Study Team IAS 2013 2 July 2013 Kuala Lumpur, Malaysia

  2. Secondary Trial Outcomes • HIV testing history = % participants reporting HIV testing in the prior 12 months • Social norms regarding HIV testing = assessed with multiple items on prevailing community attitudes towards testing • Sexual risk = self-reported of number of unprotected acts averaged over prior 6 months; Number of sexual partners • Negative life-events = reports of partnership break-up, discrimination, estrangement, neglect or violence

  3. Secondary Trial Outcomes • Discussion of HIV = proportion reports in prior 6 months • Disclosure of HIV status • HIV stigma = mean of 28 validated stigma items

  4. Secondary Trial OutcomeHypotheses • We hypothesized that in CBVCT communities, mobilization and modeling would lead to: • Increased rates of HIV testing • Increased discussion about HIV testing • Improved social norms regarding testing • Through more common discussion about HIV • Disclosure of HIV status to partners • Reduced sexual risks associated with VCT and post-test support services • All of which would lead to reduced HIV stigma at the community level These would then result in reduced HIV incidence

  5. Secondary Trial OutcomeAssessmentand Methods • Baseline assessment of 14,657 randomly selected community residents ages 18-32 • Post-intervention assessment of 56,683 randomly selected community residents ages 18-32 who provided biological samples and short behavioral questionnaire; Subset of 14,364 participants completed a detailed behavioral assessment • Response rates of 85% at baseline, 93% post-intervention long version, and 85% short survey and blood draw. Refusals < 5%, with no difference by arm

  6. HIV testing uptake • Overall increase in HIV testing in intervention communities by 25% (95%CI = 12%-39%, p=0003) • HIV testing increased by 45% among men (95%CI=1.25-1.69; p<0.0001) • 15% among women(95%CI=1.03-1.28; p=0.0134). • Many women had been tested in antenatal clinics but the increase was still significant

  7. There has been gender equity in uptake for CBVCT

  8. We reached a relatively young group of clients

  9. Proportion of the Population Using Mobile VCT

  10. Testing Uptake: 12 Months

  11. Reductions in number of sexual partners • Number of sexual partners reported by HIV positive individuals lower by 8% (95% CI: 1% - 15%, p = 0.03) • Number of sexual partners among HIV positive men lower by 18% (95% CI = 5% to 28%, p = .009)

  12. Social Norms • CBVCT resulted in more favorable social norms in intervention communities • Improved by 6% (95% CI= 03 – 09, p = 0.0001)

  13. Reductions in Multiple Sexual Partners • Multiple sexual partners among HIV infected persons reduced by 30% (95% CI: 0.54 – 0.92, p = 0.01) • Multiple sexual partners among HIV positive men lower by 29% (95% CI: 0.57 to 0.89, p = .0006)

  14. The Interventionwas Safe • No increase in negative life events in intervention communities • No increase in violence towards women, break-up of marriage or sexual relationships, neglect by family, discrimination)

  15. Stigma Reduction • No effect on stigma reduction as a secondary endpoint • Scale values on stigma measure low at baseline, little room to decline • People reluctant to report they stigmatize, even though such stigma may exist

  16. Conclusions • Modest reductions in incidence, except in older women where incidence reduced by a third • Created more favorable social norms • Effectively engaged men in HIV testing • Reduced behavioral risk among HIV+ men

  17. Conclusions • HIV testing is the first and essential in the cascade for community-level virologic suppression • A generation free of HIV necessitates widespread (and repeated) HIV testing, especially among men
