Effect of acculturation on variations in having a usual source of care in Asian Americans versus non-Hispanic whites in California
Chang, E., Chan, K. S., & Han, H. (2015). Effect of acculturation on variations in having a usual source of care in Asian Americans versus non-Hispanic whites in California. American Journal of Public Health, 105(2), 398-407. DOI: 10.2105/AJPH.2014.301950
We examined variations in having a usual source of care (USC) among non-Hispanic White and Asian American adults in California.
Data were from the 2005 and 2009 California Health Interview Survey. Using a modified Anderson model, we used multiple logistic regression to compare odds of having a USC between non-Hispanic White (n=38554) and Asian American adults (n=7566) and to examine associations with acculturation factors (English proficiency, length of residence, residence in a racially concordant neighborhood) and key enabling (employment, income, insurance) and predisposing (education) factors.
Race-related disparities between Asian Americans and non-Hispanic Whites in having a USC were no longer significant after accounting for acculturation factors. Limited English proficiency and short time in the United States (<5 years) were significantly associated with not having a USC for both races. Increasing levels of education and insurance were not associated with better access among Asian Americans.
Key differences exist in how Asian American and non-Hispanic White adults access care. Acculturation factors are key drivers of disparities and should be included in access-to-care models with Asians. Insurance and education are differentially significant for Asian Americans and non-Hispanic Whites.
