ABSTRACT

PURPOSE:

The WHO has proposed a novel model of healthy aging called intrinsic capacity (IC). However, the association between dietary patterns and IC is unclear. We aimed to investigate the prospective associations between dietary patterns and IC trajectories over a 3-year period in community-dwelling Japanese adults aged ≥ 60 years.

METHODS:

A prospective cohort study which contained nutritional status, mental status, and physical function was used. A validated 34-item food frequency questionnaire was used to determine dietary intake and to derive five dietary patterns ("fruits and vegetables", "sugar and fat", "salt and pickles", "noodle and alcohol", and "protein-rich") using principal component analysis. The composite IC score was calculated as the mean of the locomotion Z-score, cognition Z-score, psychological Z-score, vitality Z-score, and sensory regression score. A generalized estimating equation was applied for longitudinal analysis.

RESULTS:

A total of 666 enrollees were included in the analysis. The mean baseline IC was 0.07 ± 0.47. The "fruits and vegetables" dietary pattern was positively associated with composite IC score changes after adjusting for confounders (Q4 vs. Q1 mean difference [0.069], P = 0.019). Similarly, a positive correlation was observed for the "protein-rich" dietary pattern with the composite IC score changes (Q4 vs. Q1 mean difference [0.092], Q3 vs. Q1 mean difference [0.101], Q2 vs. Q1 mean difference [0.083]; all P < 0.01). However, adherence to the "sugar and fat" dietary pattern was negatively associated with composite IC score changes (Q4 vs. Q1 mean difference [- 0.072], P = 0.026). Furthermore, the percentage of animal protein to total protein intake showed a significant incremental trend in the "protein-rich" dietary pattern (P for trend < 0.001).

CONCLUSION:

The "fruits and vegetables" and "protein-rich" (animal-based protein in particular) dietary patterns were positively associated with IC changes, whereas the "sugar and fat" dietary pattern was negatively associated with IC changes. Identification and promotion of healthy dietary patterns in older adults may inform future health policies and research.
