Variations in Asian Americans: How Neighborhood Concordance Is Associated With Health Care Access and Utilization.

We examined associations of different levels of same-ethnicity neighborhood concordance with health care access and utilization among all Asian American, Chinese, Filipino, and Vietnamese adults (aged 18-64 years) using the 2005, 2007, and 2009 California Health Interview Survey and the 2010 US Census. Although associations varied by subgroup, Asian Americans in highly concordant neighborhoods were more likely to lack a usual source of care but did not lack doctor visits or experience delays in medical care and prescriptions.
