lntroduction: The normal values used to evaluate the lung function are necessary so much in seemingly healthy individuals as for those in which one shows off functional deterioration.
Objective: As the Valenciana population is product of a mixture of diverse ethnic, and because differences have been described in the Jung function that have to do with sorne factors like: anthropometric nutritional, educational tevel, among other, then our main objective was to elaborate prediction formulas which be adequate to our pediatric population.
Methods: 537 fellows were studied, coming from six schools of the urban area of Valencia, with ages understood among 6 and 17 years, 261 of the masculine sex and 276 of the feminine sex that were considered healthy, after had been previously given questionnaire (ATS DLD-78) with the purpose excluding to all those with antecedents of pathologies, smokers or that to the moment of the physical exam sorne functional deterioration was observed. lt was carried out
spirometry at least 3 times to each fellow in foot position.
Results: To the obtained data they were carried out a statistical analysis and the prediction equations were elaborated using the approaches of the ATS. As far the spirometry values, far the FVC, the FEV1 and the PEFR they were significant differences (p <0,001 being bigger the values found in the masculine sex with regard to the feminine sex; with relation to FEF25-75% were not differences statistical/y significant. Also the velues obtained by us were compared with those obtained by other North American authors that are the reference values tnet have been traditionally used our country.
Conclusion: lt would be advisable that the prediction equations recommended by us be used because they are those that more approach to our population.
