The objective of this study is to examine the effect of chronic stressor exposures on the associations between nitrogen dioxide (NO2), particulate matter and birth outcomes in New York City. We used New York City Community Air Survey (NYCCAS) and pregnancy outcome information from demographically diverse population of over 300,000 birth records linked to detailed medical data from hospital discharge diagnoses through the Statewide Planning and Research Cooperative System (SPARCS) of the New York State Department of Health between years 2006-2008.
Administrative indicators of community-level social stressors in New York City were characterized by three factors: (1) violent crime and physical disorder (2) crowding and poor access to resources, and (3) noise complaints and property crimes. We used generalized additive mixed models (GAMMSs) to investigate the potentially non-linear interaction of nitrogen dioxide and particulate matter concentrations on birth weight, adjusting for individual-level socio-demographic characteristics and sensitivity testing adjustment for co-pollutant exposures. GAMMs are used in several different fields to model covariate effects with consideration of correlation by adding random effects. This approach specifically provides useful outcomes for clustered and spatial data. The outcomes of this study would be of profound public health and policy relevance. This spatial approach enabled quantification of complex spatial patterning between chemical and non-chemical exposures, and combined effects of multiple urban exposures.
