Original StudyCombined Prevalence of Frailty and Mild Cognitive Impairment in a Population of Elderly Japanese People
Section snippets
Participants
Our national study assessed 5104 individuals 65 years and older (mean age 71 years) who were enrolled in the Obu Study of Health Promotion for the Elderly (OSHPE). Each individual was recruited from Obu, Japan, which is a residential suburb of Nagoya. Inclusion criteria required each participant to be 65 years or older at the time of examination (2011 or 2012), and to reside in Obu city. Based on previous reports, we excluded participants with a history of Parkinson disease, stroke, or
Results
The OSHPE identified 538 (11.3%) elderly participants who had symptoms of frailty and 945 (18.8%) who had MCI (Table 1). Fig. 1, Fig. 2 show our findings regarding the prevalence of frailty and MCI, respectively. We found that the prevalence of frailty increased with advancing age. Of the 538 participants who were classified as frail, 192 (34.9%) were 80 years and older. The prevalence of frailty was higher in women than in men (P < .05), and a lower level of education was significantly
Discussion
This study presents original data regarding vulnerability for physical and cognitive decline in a sample of 5104 elderly community dwellers in Japan. To our knowledge, this is the first study about frailty and MCI in this region of the world. Japan has a rapidly aging population in comparison with North, Central, and South America, as well as Europe. An examination of the differences in levels of frailty and MCI between countries may be useful in developing health care policies, especially in
