Awareness and utilization of preventive care services among the elderly under National Health Insurance.

This empirical study investigates the factors affecting the awareness and the utilization of preventive care among the elderly in Taiwan. We use data obtained from the 2005 National Health Interview Survey. A recursive bivariate probit model is adopted to analyze the factors affecting the awareness and the utilization of preventive care. The probability of awareness of free preventive care under the National Health Insurance is higher for those who are younger, Mainlanders, have received more education, have a spouse, exercise regularly, have better self-rated health status, and have chronic diseases; the probability of awareness is lower for those who are aborigines and who live in the south and the east. Awareness of preventive care services, having a spouse, living alone, having better health status, and the existence of chronic diseases increase the probability of preventive care utilization; working reduces the probability of preventive care utilization. Our result supports the views in Arrow (Am Econ Rev 53(5):941-973, 1963) that health information is an important factor determining the demand for medical care. Policymakers may enhance such preventive care service utilization by increasing the awareness of such services among the elderly.
