Nutrient and food group intakes and skeletal muscle index in the Japanese elderly: a cross-sectional analysis of the NHNS 2017.

ABSTRACT:

Objective

To examine nutrient and food intakes according to the levels of skeletal muscle mass index (SMI) in the elderly.

Design

Cross-sectional study.

Setting

Data were derived from the 2017 National Health and Nutrition Survey in Japan. SMI was calculated by dividing appendicular skeletal muscle (or lean) mass (kg) by height squared (m2). We calculated the multivariable-adjusted means of individuals' dietary intake. Dietary intake of energy, nutrients and food categories was assessed by examining dietary records using a semi-weighed method and compared according to the sex-specific quartiles of SMI.

Participants

Men and women aged ≥60 years.

Results

Among 797 men and 969 women, individuals with a higher SMI consumed more energy and more nutrients than
