Malay adults show lower respiratory function compared to other ethnicities. This study measured forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and peak expiratory flow rate (PEFR) in 223 subjects.

Area of Science:

  • Pulmonary Medicine
  • Physiology
  • Anthropometry

Background:

  • Respiratory health disparities exist across ethnic groups.
  • Establishing population-specific reference values for respiratory function is crucial for accurate diagnosis.

Purpose of the Study:

  • To assess respiratory function in a cohort of normal Malay adults.
  • To compare Malay respiratory function parameters with other ethnic groups.

Main Methods:

  • Utilized a portable electronic spirometer for data collection.
  • Standard forced expiratory maneuvers were employed to record FEV1, FVC, PEFR, and MMF.
  • 223 healthy Malay subjects aged 15-75 years participated.

Main Results:

Related Experiment Videos

  • Malay adults exhibited lower mean values for FEV1, FVC, PEFR, and MMF compared to published Caucasian and Asian data.
  • Age and anthropometric factors likely influence these observed differences.

    • Conclusions:

    • Malay adults demonstrate distinct respiratory function norms.
    • These findings necessitate the development of ethnicity-specific predictive equations for respiratory health assessment.
