Frailty Severity and Dietary Variety in Japanese Older Persons: A Cross-Sectional Study.

Abstract

Providing older person individuals with an appropriate intervention at the time of frailty onset is important to prevent the progression of the condition and the need for long-term care. However, the proper timing of starting nutritional and dietary interventions for frail older person subjects has not been fully elucidated. Therefore, in this cross-sectional study, we aimed to clarify the association between frailty and dietary variety among older persons in Japan. We surveyed sex, age, body height, body weight, body mass index, serum albumin level, dietary variety, and nutritional intake indexes in 747 community-dwelling older person individuals who underwent a comprehensive health examination in October 2014. Frailty was determined using the Kihon Checklist (25 questions). Kihon Checklist is widely used to assess frailty in Japan, and their physical, cognitive and social function was evaluated. After excluding those who did not complete the Kihon Checklist and those who required long-term care, frailty status was analyzed in 665 older person individuals. The numbers and percentages of frail, pre-frail and robust older persons were found to be 77 (11.6%), 182 (27.4%) and 406 (61.0%) respectively. Significant differences among robust, pre-frail, and frail subjects were observed in terms of age, serum albumin level, alcohol consumption, smoking, and history of diabetes. Among the nutrition-related indexes, only the dietary variety showed a significant difference. The results of ordinal logistic regression analysis showed a significant association between frailty and sex, age, smoking status, diabetes, and dietary variety score. Dietary variety was significantly associated with the progression of frailty among older persons in the community.
