Protein Intake and Disability Trajectories in Very Old Adults: The Newcastle 85+ Study.

ABSTRACT:

Objectives

To determine whether protein intake is associated with better disability trajectories in the oldest adults (≥85) and whether muscle mass and muscle strength would partially mediate this.

Design

Prospective cohort study.

Setting

Newcastle-upon-Tyne and North Tyneside, United Kingdom.

Participants

Community-dwelling older adults aged 85 at baseline (N=722).

Methods

Protein intake was estimated using two 24-hour multiple-pass recalls at baseline. Disability was measured as difficulty performing 17 activities of daily living at baseline and 18, 36, and 60 months. Trajectories were derived using mortality-adjusted group-based trajectory modelling. The effect of protein intake (g/kg of adjusted body weight (aBW)/d) on disability trajectories was exa
