Objective:

This project aims to understand relative spatial distributions in key community-level psychosocial stressors and air pollution exposures across New York City and to examine their separate and synergistic effects of childhood asthma exacerbation.

Progress Summary:

Building on Years 1 and 2 collection and examination of publicly-available indicators of community social stressors (Table 1), we have applied GIS-based methods to identify three spatially-distinct suites of stressors in NYC. These factors do not all correlate strongly with socioeconomic status in NYC; as such, our data suggests that using poverty as a proxy for social stress may be misleading, and may inadvertently confound spatially and conceptually distinct exposures. To better understand and validate these statistical analyses, we implemented two methods for assessing perceptions of stressors: 1) community focus groups and 2) a spatially-stratified citywide survey of New York City resident adults. We conducted fourteen (14) focus groups across NYC’s five boroughs to identify key community social and physical stressors. Using insights from these focus groups, we developed and implemented a systematic city-wide survey for adult NYC residents (n=1549), to capture individual-level perceived stress, mental health, and asthma outcome data. During Year 3, we used survey data to identify those community-level social stressor indicators which best predict individual stress experience. We successfully validated community-level indicators of violent crime (e.g., felony assault), but not property-related crime, physical disorder (e.g., rental unit housing violations), noise disruption, and low socioeconomic position (SEP) (e.g., less than High School education), which will be used to assess stress-related susceptibility to air pollution exposure in an epidemiologic investigation of childhood asthma hospitalizations.

During Year 3, WE ACT convened the New York City Community Air Network (NYCCAN) to engage diverse stakeholders, including community-based organizations (CBOs), environmental health advocates, academic researchers, and government agencies, for an on-going discussion around issues of social stress and chemical exposures, toward shaping research agenda and environmental health science translation. Our community-based participatory research strategy, and early scientific learnings were presented and discussed among NYCCAS stakeholders at two meetings in NYC.

Future Activities:

Together, these data will enable us to systematically examine the association between validated community-level stressor indices (e.g., poverty or crime rates) and individual stress experience. In Year 4, we will build multi-level and case-crossover epidemiological models of social stressor and air pollution exposure on child asthma hospitalizations (2005-2012) across New York City.
