Racial/ethnic differences in asthma prevalence: the role of housing and neighborhood environments

This article examines the prevalence of asthma among New York City households from 10 racial/ethnic groups, and it explores whether differential exposure to potentially adverse housing and neighborhood conditions helps to mediate observed disparities. After adjusting for household size, Puerto Rican households exhibit the highest levels of asthma, followed by other Hispanic and black households. Mexican, Chinese, and Asian Indian households exhibit the lowest levels of asthma. Results from multilevel logistic regression models indicate that exposure to deteriorated housing conditions and perceptions of low social cohesion in the neighborhood significantly elevate the odds of asthma. Controlling for these conditions along with household characteristics reduces the disproportionately high levels of asthma among Puerto Rican and black households, although they remain significantly higher than the level among white households.
