Summary
New spirometry reference equations for Hispanic/Latino adults are crucial for accurate lung disease diagnosis. Dominican and Puerto Rican Americans showed lower predicted values for FVC and FEV1, necessitating tailored reference data.
Area of Science:
- Pulmonary Medicine
- Public Health
- Biostatistics
Background:
- Accurate spirometry reference values are essential for diagnosing chronic lung diseases like asthma and COPD.
- Existing reference equations are insufficient for diverse Hispanic/Latino populations in the U.S.
Purpose of the Study:
- To develop spirometry reference equations specific to adult Hispanic/Latino background groups in the United States.
Main Methods:
- Utilized data from 16,415 participants in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL).
- Spirometry was performed using standardized methods with central quality control.
- Modeled spirometric measures from 6,425 never-smoking participants to create background-specific reference equations.
Main Results:
- Dominican and Puerto Rican Americans exhibited significantly lower predicted values and lower limits of normal for FVC and FEV1.
- These findings differed from other Hispanic/Latino groups and previously established Mexican American values.
Conclusions:
- Background-specific spirometry reference equations are recommended for Dominican and Puerto Rican individuals.
- Implementing these tailored equations can lead to more accurate diagnoses of pulmonary conditions and physiologic impairment.
