Purpose: It is unclear about physical activity who have declined cognitive function, depression and/or homebound in Japanese elderly. The present study assessed prevalence of each problem in community-dwelling elderly, and investigated profiles focused on physical activity in the subjects who had these problems by a cross-sectional design.Methods: Subjects were 737 out of 2171 (34%) self-support residents who were over 65 years old in Dazaifu City, Fukuoka Prefecture, Japan. Physical activity, depressive symptoms and cognitive function assessed using a triaxial accelerometer (Active Style Pro HJA350IT, Omron, Japan), the Japanese version of CES-D scale and a cognitive test for Japanese (Five-cog test), respectively. The personal profiles for status of going outside and communication with other person, social support (receive and provide), monthly income and years of education were assessed using a questionnaire. Depressive symptoms was judged using the cutoff-points (above 16 points) for CES-D score or use of antidepressant, and the subjects of total rank below 14 in Five-cog test were regarded as having aging-associated cognitive decline (AACD) proposed by International Psychogeriatric Association. The subjects answered "hardly ever" for at least one question asking about going outside and communication with other person were defined as homebound. The subjects divided into three groups according to numbers of the problems (nothing: NP, single problem: SP, more than two problems: DP), and then comparison of the profiles were performed among the groups. Further, factors associated with the duplication of the problems were investigated using a logistic regression analysis.Results: The AACD was found in approximately 30% of the subjects, 10% of subjects were depressive symptom or homebound. Approximately 10% of the subjects duplicated at least two problems. All duplicated cases included AACD, whereas the only combination of depressive symptom and homebound was not found. The amount of walking activity (METs/h), income and social support in DP group were significantly lower than in the NP- or SP group. Any difference in walking activity level was not observed between the NP- and SP group. Odds-ratio of walking activity adjusted for income and social support was significantly lower in the DP group than in the NP+SP group.Conclusion: Decreased walking activity was associated with duplication of the care-related problems independent of income and social support in community-dwelling Japanese elderly. Prospective study will be needed in future. Purpose: It is unclear about physical activity who have declined cognitive function, depression and/or homebound in Japanese elderly.
