    Summary

    This study developed prediction formulas for lung function in healthy females, finding that aging significantly impacts most tests more than smoking. However, smoking heavily affected specific measures like airway resistance and closing volume.

    Area of Science:

    • Pulmonary Physiology
    • Respiratory Medicine
    • Biostatistics

    Background:

    • Establishing normative data for lung function is crucial for diagnosing respiratory diseases.
    • Previous models often did not adequately account for the combined effects of aging and smoking in females.

    Purpose of the Study:

    • To derive prediction formulas for various static and dynamic lung function parameters in healthy females.
    • To evaluate the impact of aging and smoking on these lung function measures.

    Main Methods:

    • Measurements included total lung capacity, residual volume, airway resistance, lung mechanics, and transfer tests.
    • Data from 86 smokers and 100 never-smokers were analyzed using regression models.
    • Nonlinear age coefficients and smoking variables were incorporated.

    Main Results:

    • A single regression equation incorporating smoking variables was developed for all lung function tests.
    • Nonlinear age coefficients improved prediction accuracy for many lung function tests.
    • Aging had a greater impact than smoking on most lung function tests, except for airway resistance, closing volume, and others.

    Conclusions:

    • The derived formulas provide updated prediction values for lung function in healthy females.
    • Aging is a more significant factor than smoking for most lung function parameters, with notable exceptions.
    • The study highlights the differential impact of aging and smoking on specific respiratory measures.
