Abstract
Objective
The Kyoto-Kameoka Study was launched in 2011–2012 to identify the associations among
food intake, nutritional status, physical activity, oral function, quality of life
or social capital, the use of long-term care insurance (LTCI) system, and healthy
lifespan in community-dwelling older people as a part of the World Health Organization
Safe Community program.
Design
A prospective cohort study, reporting baseline demographics (cross-sectional data).
Setting and participants
We conducted 2 mailed self-administered questionnaire surveys; one is a complete population
survey with a comprehensive survey of needs in the sphere of daily life (NSDL) that
included 2 different frailty indexes, the Kihon Checklist (KCL) and the Fried phenotype,
socioeconomic status, general and psychological health, and social relationships;
followed by the more detailed Health and Nutrition Survey. A slightly modified NSDL
survey was conducted again in 2013. Survival time, LTCI certification, and medical
and long-term care costs after the baseline survey will be followed.
Results
Of 18,231 NSDL questionnaires distributed, 13,294 people responded (response rate:
72.92%; mean age 73.7 ± 6.4 and 75.1 ± 7.2 years for men and women, respectively;
12,054 people without and 1240 with LTCI certification). In people without LTCI, the
proportion of robust, prefrail, and frail were 30.3%, 59.8%, and 9.9% in men and 25.3%,
64.7%, and 10.0% in women, according to the Fried index. The proportion of frail people
as defined by KCL ≥7 was 30.8% in men and 33.3% in women.
Conclusions
The study is the first to document frailty prevalence using both Fried and KCL measures
with a complete city population survey among older Japanese in the community as a
part of World Health Organization Safe Community program. The study is expected to
provide valuable evidence of the effects of lifestyle habits on long-term care prevention
and healthy life span.
