| Outline of Research at the Start |
This study will first examine the impacts of different health insurance plans on demand for various types of medical goods and services, then evaluate the impact
of the change in copayment together with the effects of individual’s socio-demographic characteristics on health outcomes. The study will shed some light on the effectiveness and equity of the government policy on providing various types of health insurance among people with different medical needs.

| Outline of Final Research Achievements |
The study explores how health insurance copayments influence health behaviours and healthcare use among older adults in Japan, using data from the Comprehensive Survey of Living Conditions in 2013 and 2016. The findings show that increasing copayments, indicative of reduced insurance coverage, leads to greater adoption of positive health behaviors. Conversely, there is a mixed impact on risky behaviors - while cigarette consumption decreases, alcohol intake rises, especially among educated individuals and males, possibly due to cultural beliefs about alcohol's health benefits in social contexts. Higher education levels amplify changes in health behaviors, indicating the importance of socioeconomic influences. The findings offer valuable evidence-based insights for policymakers aimed at promoting healthy aging and mitigating adverse health outcomes associated with changes in health policy, both in Japan and potentially in other similar contexts globally.

| Academic Significance and Societal Importance of the Research Achievements |
This study advances understanding of how health insurance affects health behaviours. The study provides insights into behavioral responses to financial incentives in healthcare. Moreover, the findings support policymakers aiming to design evidence-based health policies for aging population.
