Study Objective
To explore the relationship between maternal body composition during pregnancy and infant birth weight in low-resource settings.
Short Abstract
The study examined how maternal body composition during pregnancy affects infant birth weight in informal settlements in Nairobi. The findings showed that maternal fat-free mass was positively correlated with infant birth weight, while fat mass had a weaker relationship. These results suggest that maternal nutritional interventions should focus on improving overall body composition to enhance infant birth outcomes.
