    Summary

    Lung function in British women is influenced by body composition and age, with smoking negatively impacting the transfer factor. These findings offer valuable reference data for respiratory health assessments.

    Area of Science:

    • Pulmonary physiology
    • Respiratory medicine
    • Human physiology

    Background:

    • Lung function parameters are crucial indicators of respiratory health.
    • Factors like age, body composition, and smoking habits can significantly influence lung function.
    • Establishing reference values for specific populations is essential for accurate clinical interpretation.

    Purpose of the Study:

    • To analyze lung function in healthy British women aged 27-74.
    • To investigate the correlation of lung function with age, stature, mass, body fat, and smoking status.
    • To provide reference values for lung function in this demographic.

    Main Methods:

    • Pulmonary function tests were conducted on 113 healthy British women.
    • Measurements included forced expiratory volume, total lung capacity, and transfer factor.
    • Data were analyzed considering age, body mass index, body fat percentage, and smoking history.

    Main Results:

    • Inspiratory capacity correlated positively with muscle mass indices.
    • Residual volume, expiratory reserve volume, and total lung capacity showed inverse correlations with body fat and stature-adjusted mass.
    • Transfer factor and its subdivisions were inversely correlated with smoking; total lung capacity decline with age was linked to increased body fat.

    Conclusions:

    • Body fat and muscle mass are significant determinants of lung volumes in women.
    • Smoking negatively affects the transfer factor, a key measure of gas exchange.
    • The study provides essential reference data for lung function in British women, highlighting the impact of physiological and lifestyle factors.
