The effects of truncal adiposity in forced spirometry: Sex differences.

The aim of the current paper is to establish the influence of truncal fat accumulation on the spirometric results of a group of healthy individuals. A cross-sectional study of 305 healthy, non-smoking adult subjects (144 males, 161 females) was conducted. Forced spirometry and dual-energy X-ray absorptiometry to quantify body fat were performed.

Relationship of Muscle Mass Determined by DEXA with Spirometric Results in Healthy Individuals.

Introduction: Muscle mass maybe a determining factor in the variability of spirometry results in individuals of the same sex and age who have similar anthropometric characteristics. The aim of this study was to determine the association between spirometric results from healthy individuals and their muscle mass assessed by dual energy X-ray absorptiometry (DEXA).

Methods: A sample of 161 women and 144 men, all healthy non-smokers, was studied.
