Higher protein intake is associated with a lower likelihood of frailty among older women, Kuopio OSTPRE-Fracture Prevention Study.
Ontology highlight
ABSTRACT: PURPOSE:Nordic nutrition recommendations (2012) suggest protein intake???1.1 g/kg body weight (BW) to preserve physical function in Nordic older adults. However, no published study has used this cut-off to evaluate the association between protein intake and frailty. This study examined associations between protein intake, and sources of protein intake, with frailty status at the 3-year follow-up. METHODS:Participants were 440 women aged 65?72 years enrolled in the Osteoporosis Risk Factor and Prevention-Fracture Prevention Study. Protein intake g/kg BW and g/d was calculated using a 3-day food record at baseline 2003?4. At the 3-year follow-up (2006?7), frailty phenotype was defined as the presence of three or more, and prefrailty as the presence of one or two, of the Fried criteria: low grip strength adjusted for body mass index, low walking speed, low physical activity, exhaustion was defined using a low life-satisfaction score, and weight loss?>?5% of BW. The association between protein intake, animal protein and plant protein, and frailty status was examined by multinomial regression analysis adjusting for demographics, chronic conditions, and total energy intake. RESULTS:At the 3-year follow-up, 36 women were frail and 206 women were prefrail. Higher protein intake???1.1 g/kg BW was associated with a lower likelihood of prefrailty (OR?=?0.45 and 95% confidence interval (CI)?=?0.01-0.73) and frailty (OR?=?0.09 and CI?=?0.01-0.75) when compared to protein intake?
