The purpose of this study was to examine the relationship between housebound (defined as elderly who go outside less than once a week) and physical fitness test (6 items of grip strength, situps, trunk flexion, foot balance, 10 m hurdle walk, 6 min walk), fitness test score, Tokyo Metropolitan Institute of Gerontology (TMIG) index of competence (3 factors of instrumental self-maintenance, intellectual activity, and social role), and General Health Questionnaire (GHQ) (4 categories of somatic symptoms, anxietynsomnia, social dysfunction, severe depression), considering the differences among gender and age. The subjects were 296 community-dwelling elderly aged≧65 (mean age : 75.5±4.9). Of the subjects, 32% were male, and 57% were elderly aged≧75. Seventy-nine (27.2%) were housebound. The rate of housebound subjects with a full score for intellectual activity, social role on the TMIG sub-scales, 10 m-hurdle walk and 6 minute walk was significantly worse than non-housebound subjects. The scores for social dysfunction and severe depression on the GHQ sub-scales for housebound were significantly higher than those for non-housebound ; and few housebound exercised more than 2 times per week or 30 minutes a day. The mental health of male housebound and housebound aged under 75 was the worst among all groups. On the other hand, female housebound and those aged≧75 had lower TMIG and physical fitness results. The characteristics of the housebound were different between genders. Among the housebound aged≧75, grip strength correlated with TMIG and GHQ-28 ; the 10 m hurdle walk correlated with severe depression, instrumental self-maintenance and intellectual activity ; and the physical fitness score correlated with GHQ-28 after adjusted for age and gender. Physical fitness correlated with TMIG and GHQ among the housebound; and few housebound exercised in daily life. Improving grip strength and walking ability may reduce the number of housebound.
