Trends in Health Care Access Disparities Among Asian and Pacific Islander Health Fair Participants in Los Angeles, 2011-2019

Objectives: Given several efforts to improve health care access in California and nationally, we studied whether linguistic and socioeconomic disparities in health care access changed from 2011 to 2019 among Asian and Pacific Islander American (APIA) people in Los Angeles, California. Methods: We analyzed survey responses from APIA health fair participants (n = 5032) in the Greater Los Angeles area from May 15, 2011, through October 20, 2019. To assess the effect of socioeconomic factors on and shifts in health care access (ie, health insurance status/regular doctor), we used a logistic regression model. Covariates included English proficiency, year, age, sex, ethnicity, income, employment, and education. We also ran an interaction analysis between English proficiency and year. Results: Health insurance access increased and doctor access remained stable throughout the study period; however, disparities in health insurance status widened by a factor of 1.08 per year between participants with high English proficiency (HEP) and participants with low English proficiency (LEP) (P = .01). People with HEP were 2.02 times more likely to have a regular doctor than people with LEP (P < .001), and this disparity persisted from 2011 to 2019 (P = .58). Participants who were young (P < .001) and male (P = .005) were significantly less likely to have health insurance and a regular doctor (P < .001) than participants who were older and female. Chinese participants were significantly more likely than Thai (P = .002) and Korean (P < .001) participants to be insured but not more likely to have a regular doctor, when controlling for health insurance. Conclusions: Policy changes targeting language and cultural barriers to care for APIA people with LEP may address the disparities observed.
