Abstract

<p> This study assessed annual rates of medical and dental treatment use and cost according to the sex, age, and business type using administrative claims data and specific health checkups of the Japan Health Insurance Association Osaka Branch. The aim was to clarify workers’ annual use of medical and dental treatment and health expenditure based on business type. Among insured persons aged between 35 and 74, we targeted 1,120,866 personnel (98.4%) who had received either specific health checkups or medical or dental treatment in FY2015. Participants were categorized into 18 different business types, as well as those who voluntarily continued health insurance coverage after retirement. We calculated annual averages and quartiles for rates of medical and dental treatment use, along with the total annual cost, and assessed whether these variables were correlated with the sex, age group, or business type. The results showed that more than 80% of the participants had received medical treatment, and just under 50% of participants had received dental treatment at least once a year. Annual medical care costs were higher in males. In dentistry, although the rate of dental care use was higher in women, dental care costs were higher and the duration of treatment was longer among males in almost every age group and business type. This suggests that males tend to receive treatment only after their conditions become severe, thus necessitating longer treatments and higher dental care costs. In addition, business types with high medical care costs tended to show high dental care costs. The results indicate that we need to improve work environments and increase awareness so that people will seek dental treatment when their dental disease severity is still mild. This is especially the case among those who work in types of businesses associated with high medical costs. </p>
