Abstract

This study was conducted to investigate the adherence of Daily Food Guides (DFGs) among older Taiwanese, and the relationship of dietary quality and frailty. 154 functional independent older adults who were retirement home residents or community dwellers involved in congregate meal services were recruited. DFGs adherence was measured using a novel Taiwanese Healthy Index (T-HEI). Dietary quality was further assessed using Dietary Approach to Stop Hypertension (DASH) and Mediterranean Diet Score (MDS). Frailty was defined using modified Fried’s criteria. Of the total participants, 12.3% were considered non-frail individuals, while 77.3% were prefrail, and 10.4% were frail. Compared to non-frail participants, prefrail and frail individuals indicated significantly lower adherence to DFGs (ptrend = 0.025). Intake of dark or orange vegetables (ptrend = 0.010), whole grains (ptrend = 0.007), as well as nuts and seeds (ptrend = 0.029) by non-frail individuals were significantly higher than the levels by prefrail and frail individuals. Linear regression model adjusted for age, gender, and functional ability showed that T-HEI was inversely associated with frailty status (β = −0.16 ± 0, p = 0.047), but additional adjustment for nutritional status attenuated the association (β = −0.14 ± 0, p = 0.103). A similar relationship was observed for DASH but not MDS (DASH: β = −0.18 ± 0.01, p = 0.024; MDS: β = −0.06 ± 0.02, p = 0.465). After adjustment for confounders, the association was not observed. However, the distribution of whole grains component in both DASH and MDS was significantly higher in non-frail than prefrail and frail individuals, indicating the importance of whole grains intake in frailty prevention. In conclusion, higher adherence to DFGs and better dietary quality were associated with a lower prevalence of frailty. Higher nutrient-dense foods intake such as whole grains, dark or orange vegetables, nuts, and seeds mark a watershed in frailty prevention.

Highlights

Participants who were retirement home residents or community dwellers participating in congregate meal services—a local government-funded program provides meals, mostly lunch, to promote nutritional health and social participation among older adults, in northern Taiwan—were invited if they were free from disability, acute or end-stage diseases, and not in ongoing cancer or disease treatments
A total of 77.3% of participants were identified as prefrail, while 10.4% were frail
The results suggest that higher dietary quality scores of Taiwanese Healthy Index (T-HEI) and Dietary Approach to Stop Hypertension (DASH) were inversely associated

Summary

Introduction

People live longer nowadays; that allows us the opportunity to study in depth the health demand in the later stage of life. Adequate intake of nutritious food for fulfilling the energy and nutritional needs is central to health and determinant to the prevention of age-associated diseases and degeneration [1]. Along with aging, the change in energy requirement and food consumption may compromise nutritional status functional ability among older adults [2]. Age-associated frailty, for instance, is a medical syndrome characterized by decreased physiological function in both strength and endurance which places older adults further on the vulnerability of developing adverse health-related outcomes and dependency [3]
