Global Lung Initiative spirometry references in healthy 3-15-year-old French children

Area of Science:

• Pediatric Pulmonology
• Respiratory Physiology
• Clinical Reference Standards

Background:

• Accurate spirometry reference values are crucial for diagnosing pediatric lung diseases.
• Existing reference values may not perfectly represent diverse pediatric populations.
• The Global Lung Initiative (GLI) provides updated spirometry reference equations.

Purpose of the Study:

• To evaluate the applicability of Global Lung Initiative (GLI) spirometry reference values.
• To assess the fit of GLI data for healthy French children aged 3–15 years.
• To determine if GLI references can be reliably used in French pediatric populations.

Main Methods:

• Spirometry data from a cohort of healthy French children (3–15 years) were collected.
• The collected data were compared against established Global Lung Initiative (GLI) spirometry reference values.
• Statistical analysis was performed to assess the goodness-of-fit between observed and predicted values.

Main Results:

• The Global Lung Initiative (GLI) spirometry reference values demonstrated a satisfactory fit with the measured data of healthy French children.
• No significant systematic bias was observed when applying GLI references to this specific pediatric cohort.
• The findings support the use of GLI equations for interpreting spirometry results in French children.

Conclusions:

• The Global Lung Initiative (GLI) spirometry reference values are appropriate for use in healthy 3- to 15-year-old French children.
• These findings validate the use of GLI standards for pediatric lung function assessment in France.
• The study supports the standardization of spirometry interpretation across different pediatric populations using GLI references.
