- Abstract
Background & Aims: The association between dietary patterns and frailty is less investigated in Asia. We aimed to investigate the prospective associations between dietary patterns and frailty index (FI) in community-dwelling Japanese older adults aged 60 years or older., Methods: A 3-year cohort collected the data on sociodemographic information, lifestyle behaviors, comorbidities, medication history, depression status, nutrition, and physical function from 2014 to 2017. Five dietary patterns including "Mediterranean-style," "sugar and fat," "salt and pickles," "noodle and alcohol," and "protein-rich" dietary patterns were identified using principal component analysis from 20 food groups obtained using a validated food frequency questionnaire. A 54-item FI was constructed on the basis of a deficit accumulation model. This project aimed to investigate the longitudinal association between dietary pattern and frailty trajectories with annual measurements over a 3-year period using a generalized estimating equation., Result: After excluding 108 participants with incomplete data at baseline, 666 participants (56.5% female, 69.4 ± 4.4 years) were included for longitudinal analysis. Our results demonstrated that adherence score to "sugar and fat" dietary pattern" (Q4 vs. Q1: mean difference [0.017], 95% CI [0.006 to 0.029]) and "salt and pickles" dietary pattern (Q3 vs. Q1: mean difference [0.010], 95% CI [0.001 to 0.020]; Q4 vs. Q1: mean difference [0.014], 95% CI [0.003 to 0.025]) were positively associated with change in FI. Adherence score to a "protein-rich" dietary pattern was negatively associated with change in FI (Q4 vs. Q1: mean difference [-0.013], 95% CI [-0.025 to -0.002])., Conclusions: "Salt and pickles" dietary pattern and "sugar and fat" dietary pattern were positively associated with frailty. In contrast, "protein-rich" dietary pattern was negatively associated with frailty., Competing Interests: Conflict of Interest The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (Copyright © 2020 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.
