Using two Nigerian datasets, this cohort study estimated the association between prenatal biomass cooking fuel exposure and birth weight among term newborns. In the primary analysis of 1,514 mother-child pairs from Kaduna, biomass fuel use was associated with 113g lower birth weight compared to liquefied petroleum gas use, with directionally consistent but smaller results in a national replication sample.

The primary analysis included 1,514 mother-child pairs from Kaduna recruited via CEGROMS, and the replication used 6,975 mother-child pairs from the 2018 Nigerian DHS. Birth weight was measured at birth or recalled by mothers. In CEGROMS, linear regression adjusted for maternal age, education, parity, BMI at birth, and child sex showed biomass fuel users had infants 113g lighter than liquefied petroleum gas users (95% CI −196 to −29). The DHS replication using linear mixed models found a smaller, non-significant 50g reduction (95% CI −103 to 2) compared to low-pollution fuel users.
