Participation in Conditional Cash Transfer Program During Pregnancy and Birth Weight-Related Outcomes

This cohort study investigates the association of participation in the Bolsa Família cash transfer program with birth weight–related outcomes. This cohort study of 4 277 523 live births found that BFP participation was associated with a reduction in low birth weight and an increase in birth weight. Outcomes were more pronounced among groups at increased risk, with a greater decrease in odds of low birth weight found among mothers with fewer years of education and indigenous mothers. This study found that BFP was associated with increased birth weight and reduced odds of LBW, with a greater decrease in odds of LBW among higher-risk groups. These findings suggest the importance of maintaining financial support for mothers at increased risk of birth weight–related outcomes.
