Timing of HIV diagnosis relative to pregnancy and postpartum HIV care continuum outcomes among Latin American women, 2000 to 2017

BACKGROUND: HIV incidence among women of reproductive age and vertical HIV transmission rates remain high in Latin America. We, therefore, quantified HIV care continuum barriers and outcomes among pregnant women living with HIV (WLWH) in Latin America. METHODS: WLWH (aged ≥16 years) enrolling at Caribbean, Central and South America network for HIV epidemiology (CCASAnet) sites from 2000 to 2017 who had HIV diagnosis, pregnancy and delivery dates contributed. Logistic regression produced adjusted odds ratios (aOR) and 95% confidence intervals (CI) for retention in care (≥2 visits ≥3 months apart) and virological suppression (viral load
