Aim: To investigate the association between homebound status and functional decline over a two-year follow-up period and the sex difference in its association. Methods: The study subjects were 2
956 independently living older individuals (1
267 men: 1
679 women). Homebound were defined as individuals who left home less than once a week.Using a Cox proportional hazard model
 we evaluated the association between homebound status and onset of functional dependence. Results: Of the 2
946 subjects
 223 (7.6%) were homebound. During the follow-up period
 153 subjects became functional dependence. After adjustment for locomotor function
 cognitive function
 depression state
 age and household type
 the hazard ratio for onset of functional dependence in association with homebound status remained significantly increased in men (HR
 3.12 [95% CI
 1.59?6.10])
 but not in women (HR
 1.43 [95% CI
 0.87-2.35]). Conclusions: This study suggests that homebound status is a risk for functional dependence in both men and women. In men
 being homebound despite intact functional ability was also a risk for functional dependence.
