Brief Summary
The goal of this study is to adapt an existing evidence based intervention for use in pregnant and lactating people (PLP) who use alcohol. Through the pilot RCT, we aim to understand if tailored intervention, Mentor Mothers+, is effective in reducing alcohol use (primary outcome) and improving antiretroviral (PrEP or ART) adherence (secondary outcomes) among pregnant and breastfeeding women living with and without HIV in a community heavily burdened by this syndemic. The investigators will conduct an pilot randomized control trial in 100 pregnant women, recruited during antenatal care (ANC) visits within the Saldanha Bay Municipality clinic in Cape Town, South Africa. The RCT will involve the delivery of brief, individual motivational interviewing sessions provided by trained mentor mothers from the community who are on either PrEP (living without HIV) or ART (living with HIV) and who stopped or reduced alcohol use during pregnancy. The enrolled participants will be followed for a 6-month period spanning both pregnancy and postpartum stages.

Outcome Measures
Primary Outcomes (2)
Reduction in alcohol use (objective)
Reduced alcohol use following the intervention delivery, measured via:dried blood spot (DBS) testing of phosphatidylethanol (PEth) levels Alcohol consumption via PEth will be defined as \<20 ng/mL representing light or no consumption, \>20-\<200 ng/mL indicating consumption and ≥200ng/mL indicating significant or heavy recent alcohol use in past 21 days.
From enrollment to the end of intervention period at 6 months
Reduction in alcohol use (self-report)
Reduced alcohol use following the intervention delivery,measured via: self-report (AUDIT-C score). Self-reported alcohol use (via participant survey) will be categorically defined via AUDIT-C score of 0 indicating abstinence versus score \>0 indicating recent alcohol use.
From enrollment to the end of intervention period at 6 months
Secondary Outcomes (5)
PrEP Initiation
From enrollment to the end of intervention period at 6 months
PrEP Adherence

ART Adherence
From enrollment to the end of intervention period at 6 months

Study Arms (2)
MM+ Intervention
EXPERIMENTALMM+ will involve mentor mother delivery of brief MI sessions individually over a series of clinic- based visits over a 6m period during pregnancy and postpartum. Intervention content, duration, and full menu of HIV prevention services offered will be finalized prior to launch. We anticipate no fewer than five to six 15-20 minute MI sessions focused on the benefits of reducing alcohol use during pregnancy, managing HIV risk among women without HIV and importance of ART use and viral suppression for reducing the risk of vertical transmission. Participants in MM+ arm will receive enhanced HIV prevention counseling integrated into routine antenatal care visits, including PrEP and ART biofeedback adherence counseling, provided by a trained study nurse. Participants in the intervention arm will also receive EtG testing (alcohol use) and corresponding biofeedback counseling.
Enhanced HIV attention control (eSOC)
ACTIVE COMPARATORSimilar to placebo pills, attention control is often used in randomized trials for behavioral interventions to control for the nonspecific effects of the intervention. Given that existing MM models focus on prevention of vertical transmission and HIV treatment and our primary interest is understanding how inclusion of alcohol reduces alcohol use improves adoption of ART/PrEP use, we will use an enhanced HIV attention control with the same time frame for the intervention (e.g. 2-3 sessions during antenatal/and 2-3 sessions during postpartum periods). Sessions will consist of educational counseling on HIV risk, partner testing modalities as well as PrEP/ART urine assay testing followed by real-time in-clinic adherence counseling delivered privately by lay counselors (different from MM+ arm to avoid contamination), all coinciding with routine ANC visits when possible.
Interventions
Participants in both study arms will receive clinic-based HIV counseling, including urine tenofovir testing and biofeedback counseling on recent PrEP or ART use. Activities unique to women enrolled in the intervention arm include: Brief motivational interviewing sessions with a mentor mother focusing on 1) EtG testing and biofeedback on recent alcohol use, 2) counseling and mentorship on ways to reduce alcohol use.
Participants in the enhanced HIV attention control arm (comparison group) will attend a similar number of study visits within the same time frame as intervention participants (5-6 sessions during 6-month timeframe including both pregnancy and postpartum). Control arm sessions will consist of one-on-one educational counseling on HIV risk, partner HIV testing modalities, as well as conducting PrEP/ART urine assay testing followed by real-time in-clinic adherence counseling delivered privately (different from study nurses delivering PrEP/ART biofeedback in MM+ intervention arm to avoid contamination), all coinciding with routine ANC visits.
