Dietary Patterns and Risk of Frailty in Chinese Community-Dwelling Older People in Hong Kong: A Prospective Cohort Study.

Abstract

Dietary pattern analysis is an emerging approach to investigate the association between diet and frailty. This study examined the association of dietary patterns with frailty in 2724 Chinese community-dwelling men and women aged > 65 years. Baseline dietary data were collected using a food frequency questionnaire between 2001 and 2003. Adherence to a priori dietary patterns, including the Diet Quality Index-International (DQI-I) and the Mediterranean Diet Score (MDS) was assessed. Factor analysis identified three a posteriori dietary patterns, namely "vegetables-fruits", "snacks-drinks-milk products", and "meat-fish". Incident frailty was defined using the FRAIL scale. Binary logistic regression was applied to examine the associations between dietary patterns and four-year incident frailty. There were 31 (1.1%) incident frailty cases at four years. Every 10-unit increase in DQI-I was associated with 41% reduced risk of frailty in the sex- and age-adjusted model (odds ratio (OR) (95% confidence interval (CI)): 0.59 (0.42-0.85), p = 0.004). The association attenuated in the multivariate adjusted model (0.69 (0.47-1.02), p = 0.056). No association between other dietary patterns and incident frailty was observed. Our study showed that a better diet quality as characterized by higher DQI-I was associated with lower odds of developing frailty. The contribution of MDS or a posteriori dietary patterns to the development of frailty in Chinese older people remains to be explored.
