This study from Aga Khan University Hospital in Mombasa, Kenya explores how heat exposure impacts maternal and perinatal health. Using time series regression models, researchers found that high temperatures and elevated Universal Thermal Climate Index (UTCI) levels were associated with increased risks of caesarean sections and low-birth-weight births. No significant associations were observed with Wet Bulb Globe Temperature (WBGT). These findings highlight the vulnerability of pregnant women and newborns in low- and middle-income countries and call for further investigation into climate-related maternal health risks, especially in heat-prone regions of Africa.
