Comparing the differences in three measures of healthy life expectancy among prefectures in Japan.

ABSTRACT: OBJECTIVE:An ecological study using secondary open data from Japanese government statistics was conducted. The study aimed to verify differences in three measures of healthy life expectancy (HLE); namely, disability-free life expectancy without activity limitation (DFLE-AL), life expectancy with self-perceived health (LE-SH), and disability-free life expectancy without care need (DFLE-CN). RESULTS:Each HLE from 47 prefectures in 2010, 2013, and 2016 was extended over time. There were strong Cronbach's coefficient alpha (?) between DFLE-AL and LE-SH (Minimum ?; 0.80, Maximum ?; 0.90) as well as between LE and DFLE-CN (Minimum ?; 0.92, Maximum ?; 0.99) in both sexes in every data year. However, the other pairs had weaker associations. In regression analysis with each HLE as a dependent variable and aging rate, mortality, the proportion of unhealthy people as independent variables, the subjective unhealthy rate had significant standardized partial regression coefficients (?) in models with DFLE-AL and LE-SH as dependent variables (Minimum ?; -?0.56, Maximum ?; -?0.34). Therefore, DFLE-CN tended to differ from the other HLEs. The subjective unhealthy rate had a significant influence on DFLE-AL and LE-SH.
