Abstract
Background: Body mass index (BMI), expressed as the ratio of body mass to height squared (kg/m(2)), involves not only fat but also lean mass. The present study aimed to clarify how BMI is associated with total muscle mass (TMM) in older Japanese women and men.
Findings: Using a B-mode ultrasound apparatus, muscle thickness was measured at nine sites (forearm, upper arm anterior and posterior, thigh anterior and posterior, lower leg anterior and posterior, abdomen, and subscapular) for 346 women (BMI 16.40 to 33.11 kg/m(2)) and 286 men (BMI 16.86 to 31.18 kg/m(2)) aged 60.0 to 79.5 yrs. TMM was estimated using the product of the sum of the muscle thicknesses at the nine sites with height as an independent variable. For both sexes, the estimated TMM relative to height squared was significantly correlated with BMI (r = 0.688, P<0.0001 for women; r = 0.696, P<0.0001 for men), but the percentage of the estimated TMM in body mass was not.
Conclusion: These results indicate that, for older Japanese women and men, BMI is a simple and convenient index for assessing total muscularity.
期刊介绍:
Journal of Physiological Anthropology (JPA) is an open access, peer-reviewed journal that publishes research on the physiological functions of modern mankind, with an emphasis on the physical and bio-cultural effects on human adaptability to the current environment.
The objective of JPA is to evaluate physiological adaptations to modern living environments, and to publish research from different scientific fields concerned with environmental impact on human life.
Topic areas include, but are not limited to:
environmental physiology
bio-cultural environment
living environment
epigenetic adaptation
development and growth
age and sex differences
nutrition and morphology
physical fitness and health
Journal of Physiological Anthropology is the official journal of the Japan Society of Physiological Anthropology.
