Extreme weather events and malaria prevention in pregnancy: a mediation analysis of antenatal care and sulfadoxine-pyrimethamine use in two malaria-endemic counties of Kenya

Key Points

To investigate how extreme weather events affect malaria prevention strategies during pregnancy, focusing on antenatal care and medication access.
Conducted a mediation analysis of antenatal care (ANC) and sulfadoxine-pyrimethamine (IPTp) use
Examined data from two malaria-endemic counties in Kenya
Analyzed how extreme weather events affect IPTp uptake through ANC.
Extreme weather events reduced IPTp uptake mainly due to ANC disruptions
The effects were most pronounced in Kisumu County
Adjustment for socioeconomic factors weakened the associations observed in unadjusted models.

Abstract

Extreme weather events reduced IPTp₃ + uptake primarily through ANC disruption in unadjusted models, with effects concentrated in Kisumu. However, these associations attenuated after adjustment, suggesting the role of underlying socioeconomic and contextual vulnerabilities.
