Not Applicable

Completed

• Conditions: HIV; Acquired Immunodeficiency Syndrome
• Interventions: Behavioral: Enhanced Counseling; Behavioral: Standard of Care

• Registration Number: NCT01683461
• Lead Sponsor: University of North Carolina, Chapel Hill

Brief 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.

Arm && Interventions

Group	Intervention	Description
Enhanced Counseling	Enhanced Counseling	Women in the intervention arm receive: (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 focused 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.
Standard of Care	Standard of Care	Women in the control arm receive the standard of care in terms of HIV counseling and testing during pregnancy. The standard of care for HIV counseling adheres to guidelines provided by the US Centers for Disease Control and the World Health Organization. Women receive one individual pre-test counseling session immediately before they are tested for HIV, and one individual post-test counseling session the same day that they are tested.

Primary Outcome Measures

Name	Time	Method
Incidence of sexually transmitted disease	14 weeks post-partum	The investigators are using biologic markers of three STIs (Trichomonas vaginalis, Neisseria gonorrhea and Chlamydia). All women are tested for STIs at baseline and 14-weeks post-partum.

Secondary Outcome Measures

Name	Time	Method
Condom use	14 weeks and 9 months post-partum	The investigators are measuring consistent condom use, unprotected sex in the past 30 days, unprotected sex since delivery (at 9 months post-partum)
