Adipose tissue in muscle: A novel depot similar in size to visceral adipose tissue (original) (raw)

American Journal of Clinical Nutrition

Background: The manner in which fat depot volumes and distributions, particularly the adipose tissue (AT) between the muscles, vary by race is unknown. Objective: The objective was to quantify a previously unstudied and novel intermuscular AT (IMAT) depot and subcutaneous AT, visceral AT (VAT), and total-body skeletal muscle mass in healthy sedentary African American (AA), Asian, and white adults by whole-body magnetic resonance imaging. IMAT is the AT between muscles and within the boundary of the muscle fascia. Design: Analyses were conducted on 227 women [AA (n ҃ 79): body mass index (BMI; in kg/m 2 ), 29.0 Ȁ 5.5; age, 45.7 Ȁ 16.9 y; Asian (n ҃ 38): BMI, 21.7 Ȁ 2.9; age, 47.2 Ȁ 19.9 y; whites (n ҃ 110): BMI, 24.9 Ȁ 5.4; age, 43.7 Ȁ 16.2 y]) and 111 men [AA (n ҃ 39): BMI, 25.6 Ȁ 3.2; age, 45.5 Ȁ 18.8 y; Asian (n ҃ 13): BMI, 24.9 Ȁ 2.5; age, 45.6 Ȁ 25.0 y; white (n ҃ 59): BMI, 25.8 Ȁ 3.8; age 44.5 Ȁ 16.3 y].
