HIV viral suppression among pregnant and breastfeeding women in routine care in the Kinshasa province: a baseline evaluation of participants in CQI‐PMTCT study

Open Access

Abstract

INTRODUCTION: Published data on viral suppression among pregnant and breastfeeding women in routine care settings are scarce. Here, we report provincial estimates of undetectable and suppressed viral load among pregnant or breastfeeding women in HIV care in Kinshasa, Democratic Republic of Congo (DRC) and associated risk factors. METHODS: This cross‐sectional study was conducted as part of a baseline assessment for the CQI‐PMTCT study: an ongoing cluster randomized trial to evaluate the effect of continuous quality interventions (CQI) on long‐term ART outcomes among pregnant and breastfeeding women (NCT03048669). From November 2016 to June 2018, in each of the 35 Kinshasa provincial health zones (HZ), study teams visited the three busiest maternal and child health clinics, enrolled all HIV‐positive pregnant or breastfeeding women (≤1 year post‐delivery) receiving ART, and performed viral load testing. Log binomial models with generalized estimating equations to account for clustering at the HZ level, were used to estimate prevalence ratios comparing participants with undetected (12 months, older age, being married, disclosure of HIV status, receiving care in an urban health zone or one supported by PEPFAR were all positively associated with viral suppression. CONCLUSIONS: The observed high level of detectable viral load suggests that high ART coverage alone ...
