Key result
Increased intrathoracic and visceral fat in males, and subcutaneous thoracic fat in both sexes, were significantly associated with decreased lung function (FEV1% and FVC% predicted).
Why the study?
Local fat distribution patterns have attracted attention, but the impact of thoracic adiposity on lung function according to sex in individuals without respiratory diseases remained to be assessed.
Is thoracic fat distribution associated with lung function in a population without respiratory diseases?
Population
455 subjects without respiratory diseases who underwent spirometry and chest and abdominal CT
Comparison
Thoracic and abdominal fat volumes measured by CT
Design
Cross-sectional study

Is thoracic fat distribution associated with lung function in a population without respiratory diseases?
Local thoracic fat distribution, particularly visceral and subcutaneous thoracic fat, is significantly associated with decreased lung function in a sex-specific manner among individuals without respiratory diseases.
Kwack et al. (2019) conducted a cross-sectional in Without respiratory diseases (n=455). Thoracic and abdominal fat volumes was evaluated on Forced expiratory volume in 1 s (FEV1) % predicted and forced vital capacity (FVC) % predicted. Increased intrathoracic and visceral fat in males, and subcutaneous thoracic fat in both sexes, were significantly associated with decreased lung function (FEV1% and FVC% predicted).
