Diaphragm weight correlates with lean body mass in patients. This finding suggests that body composition analysis can help assess respiratory muscle changes, impacting respiratory strength.

Area of Science:

  • Physiology
  • Anatomy
  • Body Composition Analysis

Context:

  • Investigating the relationship between diaphragm mass and overall body composition is crucial for understanding respiratory muscle function.
  • Autopsy studies provide valuable insights into organ weight and its correlation with physiological parameters.

Purpose:

  • To determine the correlation between diaphragm weight and body composition metrics.
  • To assess the relationship between diaphragm weight and respiratory muscle strength.

Summary:

  • Diaphragm weight was measured in 22 autopsy patients and correlated with lean body mass and fat body mass using dual-energy X-ray absorptiometry.
  • A significant correlation was found between diaphragm weight and lean body mass (r = 0.77, p < 0.01).
  • Maximal inspiratory pressure also correlated significantly with diaphragm weight, indicating a link between diaphragm mass and respiratory muscle strength.

Impact:

  • Diaphragm weight is significantly associated with lean body mass.
  • Body composition analysis may serve as a useful tool for evaluating alterations in diaphragm mass.
  • These findings contribute to a better understanding of respiratory muscle physiology and its relationship with body composition.
