Despite significant population increases, how Asian Americans ethnic subgroups vary in having a usual source of care (USC) is poorly understood.

Using data from 2005 and 2009 California Health Interview Survey, the authors examine how having a USC varies among Asian American ethnic subgroups (Chinese, Filipinos, Japanese, Koreans, Vietnamese, and South Asians), and the potential factors influencing variation in having a USC.

The authors found that significant differences in the magnitude of the variation and factors influencing having a USC were found across Asian subgroups. Korean and Japanese adults had 52 percent to 69 percent lower adjusted odds of having a USC compared with Chinese. Among all Asian subgroups, uninsured adults had 85 percent to 94 percent lower adjusted odds of having a USC. Patterns of associations with USC and key factors varied by specific Asian subgroup.   Patterns of associations for USC varied by Asian subgroup, although uninsurance persisted significantly across all subgroups. Persistent variation and heterogenous associations suggest that targeted, ethnicity-specific policies and outreach are needed to improve having a USC for Asian American ethnic adults.
