Protein intake per day and at each daily meal and skeletal muscle mass declines among older community dwellers in Japan.

ABSTRACT:

Objective

To examine associations between protein intake per day and at different meals and skeletal muscle mass declines.

Design

Two-year prospective cohort study among older community dwellers.

Setting

National Institute for Longevity Sciences-Longitudinal Study of Aging (NILS-LSA) in Japan.

Participants

Older men (n 292) and women (n 363) aged 60-87 years who participated in the baseline (2006-2008) and follow-up studies (2008-2010) of NILS-LSA and did not exhibit low skeletal muscle mass at baseline. Muscle mass was assessed using dual-energy X-ray absorptiometry at baseline and follow-up. Low muscle mass was defined as skeletal muscle mass index <7·0 kg/m2 for men and <5·4 kg/m2 for women at follow-up. Daily protein intake and protein intake at each meal w
