    Author: Trabelsi Y, Tabka Z, Richalet JP, Bouchez-Buvry A.
    Journal: Arch Pediatr; 2010 Mar; 17(3):243-8. PubMed ID: 20097550.
    Abstract:
    OBJECTIVE: The purpose of this study was to set lung function prediction equations in Tunisian children with standing height and pubertal stage as the independent variables. METHODS: Spirometric values were measured with a Minato portable Spirometer in 684 asymptomatic Tunisian children (351 boys and 333 girls), 8 to 16 years of age. The specific parameters of pulmonary function that were measured included Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 second (FEV(1)), Peak Expiratory Flow (PEF), Maximal Expiratory Flow at 50% of the vital capacity (MEF(50)), and Maximum Mild Expiratory Flow between 25 and 75% (MMEF(25-75)). The pubertal status was assessed for males and females according to the Tanner method. RESULTS: A large variation was observed in the distribution of children's age and height by pubertal stages in both sexes. Multiple regression equations for FVC, FEV(1), MEF(50), MEF(25-75), and PEF for both sexes are presented with standing height and pubertal stage as the independent variables. CONCLUSION: The establishment of validated reference values relevant to the ethnic group of the local population should significantly improve medical surveillance of respiratory diseases in Tunisian children.
