英文摘要
ABSTRACT
This F32 project aims to advance translation of pre-exposure prophylaxis (PrEP) for HIV prevention for
pregnant women at high risk of HIV infection. Nearly 80% of young women living with HIV worldwide reside in
sub-Saharan Africa and new infections among young women are double that of young men in the region. HIV
incidence is an estimated ~2-8% in women residing in high HIV prevalence regions during pregnancy and
postpartum—an incidence rate similar to high-risk groups like female sex workers and HIV-serodiscordant
couples. Acute HIV infection among pregnant and breastfeeding women poses a double burden in sub-
Saharan Africa where acute maternal HIV accounts for 26% of all mother-to-child transmissions of HIV. PrEP
is a female-controlled HIV prevention strategy that reduces HIV incidence in adherent women and could
prevent HIV in pregnant women who are unable to negotiate HIV prevention within partnerships. The World
Health Organization recommends PrEP for all individuals at substantial risk (>3% incidence rate) of HIV
acquisition and PrEP is currently being rolled out programmatically in Kenya, including in pregnant women.
PrEP adherence among pregnant African women has not been systematically evaluated to date. The proposed
F32 research proposal leverages data from an ongoing cluster-randomized trial of PrEP implementation for
HIV prevention in pregnant women (R01 AI125498-01, PI: John-Stewart) to evaluate open-label PrEP uptake
and adherence. In Aim 1, we will use baseline data to determine predictors of open-label PrEP uptake among
women who are offered PrEP during antenatal care. Identification of PrEP uptake predictors will inform who
may need intensified counseling to optimize PrEP provision. In Aim 2, we will evaluate whether PrEP
adherence declines during the postpartum period among women who initiate PrEP in pregnancy using
longitudinal modeling of drug level data. Results from Aim 2 will contribute to understanding PrEP adherence in
real-world settings using drug detection in blood samples. This will be the first study to evaluate PrEP
adherence among pregnant women and will provide data to inform PrEP adherence interventions for this
important population. The proposed research plan will prepare the F32 candidate for independent research as
a nurse-scientist and provide rigorous postdoctoral training including 1) experience analyzing data from
interventional studies, 2) formal training in new methods—including use of biomarker data in clinical research
and longitudinal analyses with repeated measures and 3) development of content area expertise in PrEP
adherence, an emerging area critical to effectiveness of this powerful HIV prevention strategy.
