BACKGROUND: Healthy life expectancy (HLE) is used as one of the primary objectives of fundamental health promotion plans and social development plans. Activity limitation is used to calculate HLE, but little study has been done to identify determinants of activity limitation in order to extend HLE. The purpose of this study is to identify diseases and injuries that commonly lead to activity limitation to prioritize countermeasures against activity limitation. METHODS: We used anonymous data from the 2007 "Comprehensive Survey of Living Conditions," collected by the Ministry of Health, Labour and Welfare of Japan according to the Statistics Act, Article 36. We used logistic regression analyses and calculated odds ratios (ORs) after adjusting for age and sex. Limitation in daily activities was applied as the dependent variable, and each @entity66 was applied as an independent variable in this analysis. Furthermore, population attributable fractions (PAFs) were calculated. RESULTS: The provided data included 98,789 subjects. We used data for 75,986 valid subjects aged 12 years or older. The following diseases showed high PAF: backache (PAF 13.27%, OR 3.88), arthropathia (PAF 7.61%, OR 4.82), eye and @entity1781 (PAF 6.39%, OR 2.01), and @entity308 and other @entity1032 (PAF 5.70%, OR 11.55). PAFs of @entity66 , @entity101 , and @entity6 were higher for males than for females; on the other hand, PAFs of @entity66 were higher among females. CONCLUSIONS: Our results indicate that @entity66 , @entity66 , and @entity146 particularly affect activity limitation.

Orthopedic, ophthalmic, and XXXX primarily affect activity limitation for Japanese males and females: Based on the Comprehensive Survey of Living Conditions.
