Association of County-Level Social Vulnerability with Chronic Respiratory Diseases Mortality in the United States.

Chronic respiratory diseases mortalities were significantly associated with county-level sociodemographic determinants as measured by the SVI in the US. These findings suggested sociodemographic determinants may add a considerable barrier to establishing health equity. Multilevel public health strategies and clinical interventions addressing inequitable outcomes of chronic respiratory diseases should be developed and targeted on areas with greater social vulnerability and disadvantage.
