Comprehensive Study of Elderly People Living in an Urban Community: The Koganei Study

Abstract

The present paper reviews a comprehensive study of elderly people carried out for 15 years in an urban community, Koganei City, Tokyo. The Koganei Study consisted of three types of study: longitudinal studies, cross-sectional studies, and case studies for the disabled. Each type of study has a particular purpose, and therefore, three types of study should be done complementarily to determine efficacious ways for successful aging.
