Déterminants de la fonction pulmonaire chez l’enfant sain en Tunisie

Abstract

Introduction Pulmonary function parameters are known to vary with age, sex, height and ethnic extraction. No normal values have been reported for pulmonary function in Tunisian children. Moreover, little attention has been paid to the factors affecting the development of lung function in Tunisian healthy children. State of art Birth weight and height, physical activity level, anthropometric, socioeconomic and environmental factors could influence the development of lung function in healthy children. Perspectives The studies conducted by our group have allowed us 1) to set reference values for spirometry in healthy Tunisian children; 2) to indicate that, in Tunisian adolescents, the use of only one morphological parameter such as height, is not sufficient, but the pubertal status could be taken into account to standardize the lung function and 3) to show the main predictive factors for pulmonary development to be the anthropometric factors such as height, weight, maximal inspiratory and expiratory thoracic perimeter, sex and age, and the environmental conditions (type of heating) in our population of healthy Tunisian children. Conclusion These findings should improve medical surveillance of respiratory diseases, stipulation of preventive and therapeutic measures in Tunisian children.
