title: Contextual effect of neighborhood environment on homebound elderly in a Japanese community.
abstract: Homebound status is associated with poorer health and disability; however, the impact of community factors on the decision to remain homebound is unclear. We applied multilevel analyses to examine the association between neighborhood environment and homebound status among Japanese community-dwelling elderly. A cross-sectional survey was conducted in February 2009 using a mailed questionnaire. A total of 4123 participants aged 20 years and over living in 72 small districts of Kashiwa, Japan, were randomly selected for the survey. Of the 1735 returned questionnaires, the 588 that were completed by individuals aged 65 years and over were used for analysis. Frequency of going outdoors was assessed and respondents going outdoors once a week or less were defined as homebound. Neighborhood environment was assessed using three subscales of the Neighborhood Environment Walkability Scale (NEWS-A) (land use mix-access, aesthetics and crime safety). Multilevel logistic regression analysis indicated that the lower score of land use mix-access at the district level was associated with the elderly being homebound after adjustment for individual demographic data, physical, psychological and social factors and district prevalence of population aged 65 years or more. This finding could contribute to devising a successful community-based strategy for homebound prevention of community-dwelling elderly individuals.
