Insurance, acculturation, and health service utilization among Korean-Americans.
This study describes the pattern and predictors of ambulatory care utilization among Korean Americans (KAs) living in Los Angeles. Data were gathered via a mail survey. Analysis employed a two-part model: logit model for factors affecting any health care use and truncated negative binomial model for frequency of use given one visit. Use of ambulatory care among KAs was low (2.80 visits during prior 12 months), compared to their counterparts in South Korea and the U.S. population. Variables associated with higher utilization included old age, health needs, and health insurance. Income had a positive effect on health care utilization decisions among the uninsured. Acculturation appeared to be neither a strong nor consistent predictor of ambulatory care utilization among KAs. Of particular concern is the finding that KAs suffer from inadequate access to care due to lack of employment-based health insurance.
