Household air pollution exposures over pregnancy and maternal blood pressure trajectories through 8 years postpartum: Evidence from the Ghana Randomized Air Pollution and Health Study (GRAPHS).

ABSTRACT:

Background

Household air pollution is a major contributor to cardiovascular disease burden in women in Sub-Saharan Africa. However, little is known about exposures during pregnancy or the effect of clean cooking interventions on postpartum blood pressure trajectories.

Methods

The Ghana Randomized Air Pollution and Health Study (GRAPHS) randomized 1414 non-smoking women in the first and second trimesters to liquefied petroleum gas (LPG) or improved biomass stoves - vs control (traditional three-stone open fire). Personal exposure to carbon monoxide (CO) was measured at four prenatal timepoints and three times over the first postpartum year. A subset of 690 participants were prospectively followed with annual resting BP measurements at 2, 4, 5, 6, 7, and 8 years postpartum. We
