Disparities in Asthma Rates Amongst Black Residents of New York City

Asthma is a chronic respiratory condition affecting around 300 million people worldwide. In the United States, Black individuals have a higher burden of asthma than White individuals. The goal of this study was to differentiate the burden of asthma between US-born and foreign-born Black residents of New York City (NYC). We use a multivariable Cox proportional hazard model with a robust variance estimate. The results indicate that foreign-born Black NYC residents have a significantly lower asthma prevalence than US-born (PR = 0.40, 95% CI = 0.21–0.76). Additionally, those 65 years and older have a lower prevalence of asthma compared to those 18–34 years old. This study shows that asthma prevalence is higher amongst US-born Black NYC residents than foreign-born, which may indicate that the healthcare needs of the foreign-born may be different from that of the native-born. Further studies are needed to elucidate this result fully.
