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 Year 1 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 are not reflective of the socioeconomic gradient, and therefore suggest that using poverty as a blunt 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 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 = 1556), to capture individual-level perceived stress, mental health, and asthma outcome data. We added an online component enabling a representative subset (n = 700) of participants to "draw" their neighborhood outline in a GIS interface, to assess the spatial relevance of community-level indicators. We are currently analyzing survey data to understand: (1) the relationships between individual perceptions of stressors (e.g., feeling safe, having knowledge of crimes committed in your neighborhood) and administrative stressor indicators (e.g., felony crime rates), (2) the role of individual and community buffers (e.g., optimism, social capital) in mediating perceived stress, and (3) mental health and asthma outcomes associated with perceived stress.

Future Activities:

Together, this data will enable us to systematically examine the association between community-level stressor indices (e.g., poverty or crime rates) and individual stress experience. In Year 3, we are: (1) working with zip code-level asthma data to begin model building, in anticipation of individual data from the New York State Department of Health, and (2) building spatially and temporally-refine air pollution exposure models, to improve individual short-term exposure assessment. In Year 4, we will build multi-level and spatially-stratified epidemiological models of social stressor and air pollution exposure on child asthma hospitalizations (2002-2012) across New York City.
