Research Progress on the Correlation Between Oral Frailty and Dietary Intake in Older Adults
-
Abstract
With the increase in age, the oral function of older adults shows an age-related decline, which limits the types, quantity, and quality of their diet. Limited dietary intake can lead to a lack of basic nutrients needed for maintaining oral health, induce a series of oral diseases, and further aggravate the deterioration of oral functions. Oral frailty is the accumulation of mild oral function decline and is an emerging concept in the field of oral health. Currently, research on oral frailty and dietary intake mostly focuses on the impact of single-dimensional oral function decline on the dietary intake, dietary structure, and dietary satisfaction of older adults, as well as the impact of different dietary structures on the status of oral health among older adults. There is still a lack of large-sample, high-quality research on the relationship between comprehensive oral function decline and dietary intake. In addition, existing oral frailty intervention measures often place a narrow emphasis on the exercise and recovery of oral function without considering the impact of dietary intake and nutritional status on the development of oral frailty. Relevant research on taking dietary intake as an entry point or using it as a comprehensive intervention method also needs to be further explored by researchers. In the future, specialized assessment and screening of dietary status may be introduced in the routine health management practices for older adults. Furthermore, targeted intervention programs could also be proposed based on the characteristics of the oral status and the dietary intake habits of older adults, so as to prevent the functional decline related to dietary intake and nutritional supplementation. Herein, we reviewed the correlation between dietary intake and oral frailty to provide new ideas and directions for formulating comprehensive management strategies for oral frailty.
