Key result
Better health exam results and proactive attitudes link to longer life and healthy life expectancy.
Why the study?
Population health varies across Japan's 47 prefectures, motivating an investigation into how health examination results and attitudes toward improving life habits relate to population health.
Are health examination results and attitudes toward improving life habits associated with population health outcomes in Japan?

Are health examination results and attitudes toward improving life habits associated with population health outcomes in Japan?
Health examination results and attitudes toward improving health habits are positively associated with population health outcomes like life expectancy in Japan.
May inform Japanese public health strategies; leaves open whether associations reflect causality or warrant intervention.
In Japan, population health with life expectancy (LE) and healthy life expectancy (HALE) as indicators varies across the 47 prefectures (administrative regions). This study investigates how health examination results, including attitude toward improving life habits, are associated with population health. The association between health checkup variables and summary population health outcomes (i.e., life expectancy and healthy life expectancy) was investigated using a cross-sectional ecological design with prefectures as the unit of analysis. The medical records, aggregated by prefecture, gender, and age in the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB) Open Data Japan, were used as health checkup variables. Body weight, blood pressure, liver enzymes, drinking habits, smoking habits, diabetes, serum lipids, and answers to questions regarding attitude toward improving health habits were significantly correlated to population health outcomes. Multiple regression analysis also revealed significant influence of these variables on population health. This study highlights that health examination results, including attitude toward improving health habits, are positively associated with population health. Consequently, implementing measures to improve health habits in response to the examination results could help the population maintain a healthy life.

Nagakura et al. (2021) conducted a cross-sectional in Population health. Health examination results and health habits was evaluated on Life expectancy and healthy life expectancy. Health examination results and attitudes toward improving health habits were significantly associated with population health outcomes, including life expectancy and healthy life expectancy.
