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

| Sumario: | [EN]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. Partial correlation and multiple linear regression analyses were performed. In females, abdominal fat was negatively correlated with forced vital capacity (FVC) and forced expiratory volume in one second (FEV1). In males, thoracic fat was negatively correlated with respiratory variables, as was abdominal fat. In the multiple linear regression, FEV1 was the spirometric parameter that showed higher R2 values in both sexes. Truncal fat had a greater influence on FEV1 than on FVC. In males, no significant differences between the influence of thoracic and abdominal fat on spirometric results were found, and total body fat was shown to have more influence than regional. In females, the influence of abdominal fat was higher. 1. Introduction The negative effects of body fat accumulation are demonstrated in a series of chronic diseases, mainly cardiovascular and metabolic diseases such as diabetes. In the case of ventilatory function, it has not yet been established what the real influence of the body’s fat compartment is on ventilatory function, and only in individuals who are severely obese has the association between excessive body fat accumulation and pulmonary function impairment been demonstrated (Ceylan et al., 2009; Leone et |
