Kuala Lumpur, Malaysia, 30 June - 3 July 2013 Enhancing male partner involvement How else can we reach these men if they will not come to clinic?

Kuala Lumpur, Malaysia, 30 June - 3 July 2013 Home-based HIV Counseling and Testing (HBCT) Door-to-door HBCT –Acceptability >70% –Testers ~25% men ~13% couples ≈4 % pregnancy For PMTCT, it may be more efficient to focus on testing men when their partners are pregnant Alsop Z. Lancet Naik BMC Public Health 2012.

Kuala Lumpur, Malaysia, 30 June - 3 July 2013 Men as Partners in PMTCT (MAP) study Primary objective Compare effectiveness of home visit vs. invitation for clinic visit in increasing male partner HIV counseling and testing among women seeking prenatal care Secondary objectives Evaluate relationship stability and intimate partner violence following male partner HIV testing

Kuala Lumpur, Malaysia, 30 June - 3 July 2013 Study population and setting Study population Pregnant women unaccompanied by partners On 1 st antenatal care (ANC) visit Legal age No couple HCT in this pregnancy Reside in area with partner for ≥ 6 weeks Ahero Sub-district Hospital, Nyanza, Kenya Antenatal HIV-1 prevalence ~ 20% Nyanza 13.9% National 6.3% HIV prevalence

Kuala Lumpur, Malaysia, 30 June - 3 July 2013 Strengths and limitations Strengths Randomized design Generalizable to high HIV prevalence and resource- limited settings with similar partnerships Easily implementable, conducted after routine prenatal HCT Limitations Excluded single and those in unstable relationships Short follow-up period, unable to assess long-term outcomes such as HIV free survival, linkage to care, cost-effectiveness

Kuala Lumpur, Malaysia, 30 June - 3 July 2013 Conclusions Home visits for male partner testing and mutual disclosure –highly acceptable –enhanced access to male partners and couple HCT (85%) –did not adversely affect short-term relationship status –found high prevalence of HIV among male partners HIV serodiscordant couples
