Factors related to frequency of engaging in outside activities among elderly persons living an independent life at home.

We examined by cross-sectional design the association between the frequency of outside activity and the demographic, health problem, lifestyle, psychosocial and environmental factors among 239 community-dwelling elderly Japanese people (105 men and 134 women) aged 65 years and older, who lived independently at home. The associations of the outside activities more than 6-7 days per week based on a categorical questionnaire choice with potential factors were expressed by odds ratio (OR) and 95% confidence interval (CI) calculated through logistic regression analysis by sex. The proportions of those engaging in outside activity more than 6-7 days per week were 38.
