| Abstract
|
| [Objective] To analyze the bioelectrical characteristics of university students with yang-deficiency constitution using bioelectrical impedance measurement technology，and to provide objective evidence for its physiological functional features. [Methods] A total of 41 subjects with balanced constitution and 38 subjects with yang-deficiency constitution underwent bioelectrical impedance testing. Then the functional states of various systems，tissues，and organs were compared between the two groups. [Results] Significant differences in the composition ratio of functional status grading were observed between the two groups in multiple systems，including the respiratory，digestive，endocrine，cardiovascular，and nervous systems（P<0.05）. Specifically， functional states were generally lower in regions such as the trachea，stomach，adrenal medulla，thyroid，and carotid arteries in the yang- deficiency group. No significant differences were found in the immune or urogenital systems. Additionally，the secretion level of adrenal medullary hormones and acetylcholine in the yang-deficiency group were significantly lower than those in the balanced constitution group（P<0.05）. Correlation analysis revealed a negative correlation between the yang-deficiency constitution transformation score and the functional status of multiple systems（r<0，P<0.05）. [Conclusion] University students with yang- deficiency constitution exhibit generally lower physiological functional states across multiple systems and organs. Bioelectrical impedance measurement can serve as an objective tool for functional assessment of yang-deficiency constitution. |
