Summary

New prediction equations for pulmonary functions in Indian girls were developed using anthropometric data. These equations can serve as vital referral standards for assessing lung health in young females.

Area of Science:

  • Pediatric pulmonology
  • Biometrics
  • Public health

Background:

  • Pulmonary function assessment is crucial for monitoring respiratory health in children.
  • Establishing population-specific prediction equations is essential for accurate interpretation of lung function tests.
  • Existing pulmonary function data for Indian girls may not fully represent current anthropometric standards.

Purpose of the Study:

  • To evaluate pulmonary functions in a cohort of Indian girls.
  • To develop and present novel prediction equations for key pulmonary function parameters.
  • To establish reference standards for lung function in Indian girls aged 5-15 years.

Main Methods:

  • A cross-sectional study involving 1038 healthy Indian schoolgirls aged 5-15 years.

  • Measurement of anthropometric parameters including height, weight, sitting height, and chest circumference.
  • Assessment of pulmonary functions: Forced Expiratory Volume in 1 second (FEV1), Forced Vital Capacity (FVC), FEV1/FVC ratio, and Peak Expiratory Flow Rate (PEFR).

    • Main Results:

    • Pulmonary function parameters were comparable to existing Indian standards.
    • Strong correlations were observed between lung function variables and anthropometric indices.
    • Multiple regression equations were developed to predict FEV1, FVC, and PEFR using height, fat-free mass, age, and chest circumference.

    Conclusions:

    • The developed regression equations provide reliable predictions for FEV1, FVC, and PEFR in Indian girls.
    • These equations utilize readily measurable anthropometric variables, facilitating clinical application.
    • The study establishes new referral standards for pulmonary function assessment in this demographic.
