This study developed new spirometry reference equations for adults in the Lublin Region, finding existing standards may underestimate lung function. New equations are crucial for accurate respiratory health assessments in this population.

Area of Science:

  • Pulmonology
  • Medical Statistics

Background:

  • Spirometry is a key lung function test, relying on reference equations for accurate interpretation.
  • Existing prediction formulas, like those from the ECSC, may not accurately reflect lung function in diverse local populations.
  • Accurate lung function standards are vital for assessing respiratory health, disease impact, and environmental influences.

Purpose of the Study:

  • To establish localized lung function prediction equations for forced vital capacity (FVC) and forced expired volume in the first second (FEV1).
  • To determine appropriate normal reference values for adults in the Lublin Region, Poland.
  • To compare the reliability of new equations against existing standards for the local population.

Main Methods:

  • Analysis of lung function screening data from 136 adults (aged 40-80) in the Lublin Region.

  • Calculation of FVC and FEV1 reference values using linear multiple regression with age and height as predictors.
  • Comparison of derived equations with established ECSC reference values.

    • Main Results:

    • New prediction equations for FVC and FEV1 were developed for males and females in the Lublin Region.
    • Calculated FEV1 and FVC values for the local population were generally higher than those predicted by ECSC equations.
    • Significant differences highlight potential inaccuracies when applying non-local standards.

    Conclusions:

    • Existing spirometric reference values, particularly ECSC-based ones, may underestimate lung function in the Lublin Region adult population.
    • Localized prediction equations are necessary for accurate spirometry interpretation in this demographic.
    • Continuous refinement of spirometric standards is needed to ensure clinical relevance and accuracy across different populations.
