Abstract
Behavioral and environmental risk factors, such as maternal smoking during pregnancy and in-utero exposure to extreme weather events are significant threats to infants’ health at birth. Effects of these risk factors on infant health have been extensively studied using traditional methods, while mostly neglecting possible heterogeneity in the effects. Causal machine learning has emerged as an effective approach for estimating heterogeneous treatment effects, but identifying the causal pathways driving heterogeneity remains challenging. This dissertation consists of three essays that apply and adapt causal machine learning techniques to study heterogeneity in the effects of different behavioral and environmental risk factors on health at birth. Chapter 2 uncovers heterogeneity in the effects of maternal smoking during pregnancy on infant health at birth by proposing a novel decomposition approach, while Chapter 3 studies how smoking during pregnancy can be regulated using smoking bans. Chapter 4 studies the effects of in-utero heat shock exposure on health at birth and possible heterogeneity in the effect found.
