Abstract P126: Consumption of Fruits and Vegetables and Risk of Frailty
Background: Frailty is a geriatric syndrome characterized by reduced physiologic reserve, which is manifested by increased risk of falls, disability, institutionalization or death. No previous study has assessed he potential dose-response relationship between fruits and vegetables consumption and risk of frailty in older adults.
Methods: This study included 2008 individuals aged ≥60 yrs from the Seniors-ENRICA cohort study. At baseline, food consumption was obtained with a validated diet history. According to the Spanish Society of Community Nutrition, a portion of fruit was defined as 120-200 gr and a portion of vegetables as 150-200 gr. Participants were followed up during 3.5 years to assess incident frailty, which was defined as per the Fried criteria. Analyses were performed with logistic regression and adjusted for dietary and non-dietary confounders.
Results: During follow-up, 136 cases of incident frailty were ascertained. The multivariate odds ratios (95%CI) of frailty among those who consumed 0, 1, 2, 3 ≥4 portions of fruit per day were, respectively: 1.00, 1.03 (0.51-2.07), 0.71 (0.38-1.35), 0.41 (0.19-0.87) and 0.67 (0.26-1.74). The corresponding results among those who consumed 0, 1, 2, 3 ≥4 portions of vegetables a day were: 1.00, 0.68 (0.40-1.15), 0.52 (0.32-0.83), 0.46 (0.19-1.13) and 0.71 (0.15-3.33). When results for fruits and vegetables were combined, a progressive decreased risk of frailty was observed among those who consumed 2, 3, 4 and 5 portions/day, compared to those who consumed ≤1 portions/day: 0.39 (0.22-0.68), 0.45 (0.25-0.79), 0.34 (0.18-0.62) and 0.22 (0.10-0.49), respectively. There was a threshold around 5 servings of fruits and vegetables, so that no additional benefit was seen among participants who consumed ≥6 portions/day: 0.39 (0.16-0.94).
Conclusion: Higher consumption of fruits and vegetables is associated with lower risk of frailty. These results provide support for the current recommendation to increase consumption of fruit and vegetables to promote health in older adults.
