An Econometric Analysis of the Difference between Exercisers and Non-Exercisers in Medical Care Use

Abstract

This study intended to look into the effects of exercise on health care utilization using the Korea Medical Panel data adjusting for the perspective of medical needs. In other words, it intended to find out if there exist any differences in medical service uses between people who exercise and those who do not, and to quantify the differences, if any. The results of this study suggest that exercise does have great impact on health care utilization and that the type of exercise also affects the health care utilization. In the case of medical care experience estimations (in percentages) including both inpatient and outpatient care, the estimated values of strenuous exercisers were 7.8~10.7%p smaller than non-exercisers, while those of moderate exercisers fell by 8.0~12.0%p compared to non-exercisers and those of walkers went down by 6.1~8.7%p. The estimations for outpatient visits and days of inpatient stay (weighted three times higher than outpatient visits) also demonstrate similar trends. People doing vigorous physical activity were estimated to have 14.3~19.8% less physician visits and stays than non-exercisers, while those exercising moderately were to have 15.0~22.2% less and walkers, 11.3 ~16.0% less. Having overcome limitations in Korean data and research methods, the results of this study support many other research findings that conclude that exercise reduces medical care use. It is believed that they also demonstrate the potential of exercise as an important policy tool that will contribute to the reduction of medical care use and expenses. Therefore, authorities are urged to ensure that health promotion policy should be based on such research results.
