Understanding the associations between exposure to residential greenness during pregnancy and birth weight can assist urban planning and policymaking for improving infant health. However, existing studies did not reach a consistent conclusion due to the use of different urban greenness measurements, varying number of samples, and adjusting for different confounding covariates. There are multiple greenness measurements reflecting the differences in conceptualizing greenness, such as normalized difference vegetation index, tree canopy, vegetation fraction, and urban neighborhood green index. In this study, I will compare different urban greenness measurements and examine how they are associated with birth weight in the 10 most populous counties in the metropolitan Atlanta, Georgia. Regression models will be used and adjust for the individual-level sociodemographic, medical, and behavioral characteristics that are recorded in the birth certificate dataset as well as the proximity to the nearest park and the census-tract-based socioeconomic status. By identifying the measurements that are more associated with birth weight, more effective improvement actions on urban environment can be suggested for infant health promotion.
