Computed tomography-based skeletal muscle and adipose tissue attenuation: Variations by age, sex, and muscle.

ABSTRACT:

Objective

This study aimed to investigate how skeletal muscle attenuation and adipose tissue (AT) attenuation of the quadriceps, hamstrings, paraspinal muscle groups and the psoas muscle vary according to the targeted muscles, sex, and age.

Design

Population-based cross-sectional study.

Setting

Community-dwelling old population in Reykjavik, Iceland.

Subjects

A total of 5331 older adults (42.8% women), aged 66-96 years from the Age, Gene/Environment Susceptibility (AGES)- Reykjavik Study, who participated in the baseline visit (between 2002 and 2006) and had valid thigh and abdominal computed tomography (CT) scans were studied.

Methods

Muscle attenuation and AT attenuation of the quadriceps, hamstrings, paraspinal muscle groups and the psoas muscle were
