Normal spirometric standards in young adult Indian population

Area of Science:

• Pulmonary Medicine
• Respiratory Physiology
• Biostatistics

Background:

• Spirometric reference values require matching individual characteristics like ethnicity and environment.
• Accurate lung function assessment is crucial for diagnosing respiratory conditions.

Purpose of the Study:

• To determine lung function parameters in healthy young Indians.
• To derive reliable prediction formulas for spirometry in the Indian population.

Main Methods:

• Computerized spirometry performed on 298 healthy, non-smoking medical students.
• Statistical analysis and derivation of prediction equations using regression models.

Main Results:

• Significant gender differences observed in all lung parameters.
• Height was the primary determinant of FEV1 and FVC in both genders.
• Derived prediction values showed variations compared to other Indian and international populations.

Conclusions:

• The developed regression norms provide accurate spirometric predictions for young Indian adults.
• These norms can aid in the clinical assessment of lung function in the target demographic.
