Prenatal Care and Birthweight in Mexico

Abstract

We estimate the marginal impact of prenatal care (PNC) on birth outcomes in Mexico using nationally representative data on about 14 million births from 2009 to 2014. Given the possible self selection into PNC, we attempt to identify the causal impact of PNC on birth outcomes by estimating an instrumental variable model. We find positive impacts of increased prenatal visits on birthweight (BW), length and apgar score of the newborn. Moreover, the impacts of PNC on birth outcomes differ by mother’s education, development level of the municipality where the mother resides and BW distribution. We also find suggestive evidence that PNC visits affect birth outcomes through the reduction in pre-term births.
