Subjective Evaluation of Chewing Ability and Self-Rated General Health Status in Elderly Residents of Japan

Abstract

The purpose of the present study was to statistically analyse the relationship between subjective evaluation of chewing ability and self-rated general health status in elderly Japanese residents. Interviews were conducted with 1, 544 respondents over 65 years of age in Yamanashi Prefecture, Japan. The interviews included questions concerning age, sex, health status, capacity to understand conversation, chewing ability, and ADL status. First, the age-adjusted odds ratio between subjective evaluation of chewing ability and self-rated health status was 2.242 (p≤0.01). Second, the age-adjusted odds ratio between respondentive evaluation of chewing ability and ADL status was 2.572 (p<0.01). Third, the age-adjusted odds ratio between self-assessment of chewing ability and the degree of understanding conversations was 5.290 (p≤0.01). These results suggest that chewing ability is related to self-rated general health, ADL status, and the degree of understanding conversation among the elderly.
