Insights
This study established lung function reference values for North Indian boys aged 10-19. Ethnic-specific prediction equations are crucial for accurate spirometry interpretation in diverse populations.
Area of Science:
- Pediatric Pulmonology
- Respiratory Physiology
- Anthropometry
Background:
- Spirometry is essential for assessing lung function in children.
- Establishing population-specific reference values is critical for accurate diagnosis.
- Previous studies have shown variations in lung function across different ethnic groups.
Purpose of the Study:
- To determine lung function reference values for healthy male children in North India.
- To establish best-fit regression equations for spirometry parameters.
- To highlight the importance of ethnic-specific prediction equations.
Main Methods:
- Spirometry was performed on 177 healthy male children aged 10-19 years in Patiala, North India.
- Regression analysis was used to determine the best-fit equations for lung function parameters.
- Lung function parameters were analyzed in relation to age, height, weight, and body surface area (BSA).
Main Results:
- A linear relationship was observed between lung function parameters and age, height, weight, and BSA.
- The lung function values obtained were higher than those reported in South Indian studies.
- Results were comparable to other North Indian studies but lower than Western studies.
Conclusions:
- Ethnic-specific prediction equations are necessary for accurate spirometry interpretation.
- Lung function values vary significantly between different ethnic groups.
- This study provides valuable reference data for North Indian children.
Abstract:
We performed spirometry on 177 male healthy children from Patiala, North India between 10 to 19 years age. The best fit regression equations for different functions were determined for each parameter. A linear relationship of lung function was observed with age, height, weight and BSA. Our results have been higher than the South Indian studies but closer to other North Indian studies. Similar comparison with western studies reveals that their subjects have higher lung function values than our subjects. It is clear that grossly erroneous conclusions may be reached unless prediction equations for lung function tests for a given ethnic group are derived from studies upon the same ethnic group.
