Abstract
Background: The private health insurance market is expanding with the reduction in the national health insurance coverage rate. The purpose of this study was to compare the effects of private health insurance on public health by using the 6th Korea National Health and Nutrition Examination Surveys (KNHANES, 2013–2015) data.
Methods: The impact of private health insurance coverage on hypertension and diabetes control in participants aged 30–70 years was examined by combining data from the KNHANES, 2013–2015. A logistic regression was performed by adjusting for income, educational level, marital status, smoking status, drinking at least once, and number of walking days per week, and odds ratios and 95% confidence intervals for the relative risk were calculated.
Results: The rate of control of diabetes was significantly higher in private health insurance subscribers, but the rate of control of hypertension was not significantly different.
Conclusion: As the private health insurance market expands, it will be necessary to seek limitations and security directions for national health insurance through further studies on the disease control status of private health insurance subscribers.
