Abstract
The literature suggests that Korean Americans underutilize health services. Cultural factors and language barriers appear to influence this pattern of low utilization, but studies on the relationships among length of stay in the U.S., English use and proficiency, and utilization of health services among Korean Americans have yielded inconsistent results.This study examines whether English language use and proficiency plays a mediating role in the relationships between length of stay in the U.S. and health insurance coverage, access to and use of care.
Structural equation modeling was used for mediation analysis with multiple dependent variables among Korean Americans (N=555) using baseline data from a large trial designed to increase Hepatitis B testing.
The results show 36% of the total effect of proportion of lifetime in the U.S. on having health insurance was significantly mediated by English use and proficiency (indirect effect=0.166, SE=0.07, p<.05; direct effect=0.296, SE=0.13, p<.05).
Proportion of lifetime in the U.S. was not associated with usual source of care and health service utilization. Instead, health care utilization was primarily driven by having health insurance and a usual source of care, further underscoring the importance of these factors.
A focus on increasing English use and proficiency and insurance coverage among older, female, less educated Korean Americans has the potential to mitigate health disparities associated with reduced access to health services in this population.
