How applicable are GLI 2012 equations to a sample of Middle Eastern school-age children?
1Al-Zaytoonah University of Jordan, Amman, Jordan.
Background:
The Global Lung Function Initiative attempted to formulate global all-age lung function equations. The suitability of these equations to Middle Eastern children was never evaluated; this study will evaluate these equations in addition to other regional ones.
Methods:
Spirometry was conducted for 582 (311 boys) healthy 6- to 13-year-old Jordanian children. z scores, predicted values, percent predicted values, and frequency of records below lower limit than normal (LLN) were calculated for each child using the studied equations.
Results:
Although none of the studied equations produced a perfect representation of the study data, the GLI 2012 equations for Caucasians were the most suitable.
Conclusion:
GLI 2012 equations for Caucasians are a reasonable fit for Jordanian school-aged children.
