Efficacy of HIV Post-Test Support for ANC in South Africa

Summary

This is a randomized controlled intervention trial with 1,500 pregnant and postpartum women to examine the efficacy of an enhanced model of ongoing post-test support for women attending antenatal and postnatal care in KwaZulu-Natal, South Africa. Through the intervention, the investigators will tailor voluntary counseling and testing (VCT) for HIV to the ANC setting and provide a continuum of psychosocial support for pregnant women through: (1) a standardized health education video before HIV pre-test counseling; (2) HIV pre- and post-test counseling sessions that prepare women for decisions related to testing, serostatus disclosure and anti-retroviral (ARV) prophylaxis and help women plan strategies for sexual risk behavior change; (3) two additional post-test counseling sessions postpartum focusing on legal education and referral, partner testing, sexual risk behavior change and family planning decisions and; (4) an active referral system to post-test support groups run by a clinically trained staff psychologist and (5) an active referral system to legal services run by a lawyer at the clinic.

Through this intervention trial the investigators will be testing the following hypotheses:

H1: Women receiving the intervention will have significantly lower sexual risk of HIV at 14 weeks and 9-months post-partum as compared to women in the control arm. Sexual risk of HIV will be measured by: STI incidence (Trichomonas vaginalis, Neisseria gonorrhea and Chlamydia), consistent condom use, unprotected sex in past 30 days, and unprotected sex since delivery.

H2: Women receiving the intervention will report significantly better outcomes related to prevention of mother to child transmission (PMTCT) service uptake at 14 weeks and 9 months post-partum as compared to women in the control arm. PMTCT service uptake will be measured by acceptance of HIV VCT among HIV-positive and HIV-negative women; acceptance of ARVs, adherence to national infant feeding guidelines, and family planning use among HIV-positive women.

H3: Women in the intervention arm will report significantly better psychosocial outcomes at 14 weeks and 9 months post-partum as compared to women in the control arm. Psychosocial outcomes will be measured by: perceived social support, emotional distress, and partner violence among HIV-positive and HIV-negative women.

Interventions

BEHAVIORAL

Enhanced Counseling

Women in the enhanced counseling arm receive the following intervention package: a video prior to their HIV pre-test counseling session that prepares them for decisions they will have to make regarding HIV testing and PMTCT participation, a pre-test counseling session and post-test counseling session with their nurse midwife/counselor, and two additional post-test counseling sessions with the same nurse midwife at 6 and 10 weeks postpartum. Women in the enhanced counseling arm also have access to ongoing support groups and legal support if needed at the clinic.

BEHAVIORAL

Standard of Care

Women in the standard of care arm receive HIV pre and post-test counseling at their first antenatal visit. The counseling provided to them adheres to international guidelines for HIV counseling and testing developed by US CDC and the World Health Organization.
