ABSTRACT
BACKGROUND:
Diet may be associated with frailty.OBJECTIVE:
We aimed to evaluate the associations between empirically derived dietary patterns and frailty in older men.DESIGN:
Prospective cohort study.SETTING:
The Concord Health and Ageing in Men Project, Sydney, Australia.PARTICIPANTS:
785 community-dwelling older Australian men aged 75 years and older.METHODS:
Men underwent dietary assessment using a validated dietitian-administered diet history questionnaire. Factor analysis identified three dietary patterns. Multinomial logistic regression was conducted between frailty and dietary patterns for cross-sectional analyses and longitudinal analyses over a 3-year follow-up. Frailty was defined by the Fried frailty phenotype.RESULTS:
Of the 785 men, pre-frailty was prevalent in 47.1% (n = 370), and frailty in 8.3% (n = 65). In fully adjusted cross-sectional analyses, the top tertile and a higher 'vegetables-legumes-seafood' dietary pattern score were associated with reduced prevalence of frailty (OR 0.34 [95% CI 0.12, 0.93, P = .036]) and OR 0.50 [95% CI 0.30, 0.83, P = .007] respectively). The top tertile of the 'discretionary-starchy vegetables-processed meats' dietary pattern was also associated cross-sectionally with increased prevalence of pre-frailty (OR 1.75 [95% CI 1.08, 2.83, P = .022]). Of the 296 robust men in fully adjusted longitudinal analyses, the incidence of pre-frailty was 52.4% (n = 155), and frailty was 5.4% (n = 16) over a 3-year follow-up. The middle tertile of the 'vegetables-legumes-seafood' dietary pattern had a non-significant trend towards reduced incident pre-frailty (OR 0.52 [95% CI 0.27, 1.00, P = .050]).CONCLUSION:
Consumption of a 'vegetables-legumes-seafood' dietary pattern appears to be less favoured by frail older men.Key words
