Abstract

Despite well-known benefits of health care utilization for the effective management of chronic diseases, the underlying mechanism of understanding health care utilization in ethnic minority population has not been systematically explored. The purpose of this paper is to examine the predictive ability of a health care utilization model by analyzing the interplay between predisposing, enabling, and need factors. The sample consisted of hypertensive Korean American immigrants (KAIs) 40-64 years of age who participated in a self-help intervention for high blood pressure care (SHIP-HBP). Using structured questionnaires, data were collected from 445 KAIs at baseline and analyzed with path analysis. Insurance status and relevant medical history were not just strong direct effects but also carried the most total effect on the health care utilization of these patients. Life priorities, years of residence in the US and perceived income level exerted indirect effects through the participants' insurance status. Our statistical analysis indicated a good fit for the proposed model (x 2 = 28.4, P = 0.29; NFI = 0.91; CFI = 0.99; RMSEA = 0.02). Overall, the model explained 18% of the variance in health care utilization of hypertensive KAIs. These findings strongly support a need to improve access to health care for KAIs by introducing a variety of community resources and building sustainable community infrastructures.
