Comparison of pulmonary function in immigrant vs US-born Asian Indians

Area of Science:

• Pulmonary Medicine
• Environmental Health
• Sociology

Background:

• Investigating disparities in pulmonary function among distinct populations.
• Understanding the impact of birthplace and environment on respiratory health.
• Examining the Asian Indian diaspora's health outcomes.

Purpose of the Study:

• To compare pulmonary function between US-born and India-born Asian Indians.
• To determine if country of birth, environmental, or socioeconomic factors influence lung function.
• To identify potential causes for observed differences in respiratory health.

Main Methods:

• Pulmonary function tests including FEV(1), FVC, and FEF(25-75) were administered.
• Participants included healthy, non-smoking, adult Asian Indians (India-born and US-born).
• Socioeconomic status was assessed using the Hollingshead Index of Social Position.

Main Results:

• US-born Asian Indians demonstrated significantly higher pulmonary function values (FVC, FEV(1), FEF(25-75)) compared to India-born individuals.
• These differences were more pronounced in women.
• No significant differences in socioeconomic position were found between the two groups.

Conclusions:

• US-born Asian Indians possess enhanced lung function compared to immigrant Asian Indians.
• Environmental factors associated with country of birth are likely responsible for these observed pulmonary function differences.
• Lung volumes may exhibit year-of-birth trends influenced by environmental conditions.
