PEREZ-PADILLA, José Rogelio; REGALADO-PINEDA, Justino  and  VAZQUEZ-GARCIA, Juan Carlos. Spirometric reproducibility and reference values in Mexican workers claiming disability. Salud pública Méx [online]. 2001, vol.43, n.2, pp.113-121. ISSN 0036-3634.

OBJECTIVE: To decribe spirometric function and adjustment to foreign prediction equations in Mexican workers claiming work related disability. MATERIAL AND METHODS: We reviewed 5771 spirometries done at the Mexican National Institute of Respiratory Diseases performed with equipment and methods proposed by the American Thoracic Society. With the spirometries we generated multiple regression equations separated for men and women based on age and height, compared to other in common use reported by Knudson and Hankinson in North America and by Quanjer in europeans. RESULTS: 80% of the tests were reproducible for FVC and FEV1 according to ATS, wheras 10% were reproducible for neither. Mean FVC in men was 12% above values reported by Quanjer, 22% above Knudson, 3% above Hankinson and 6% above Rodriguez-Reynaga, whereas similar values for women were 18%, 10%, 0% and 1%. Excluding obese and those who had less than 2 acceptable maneuvers, the numbers increase by 1-2%. FEV1 was also above predicted. CONCLUSIONS: Most workers requesting disability are able to generate a reproducible spirometry. However for the same gender, age and height, workers had a FEV1 and a FVC above normal values reported by Knudson and Quanjer and are more similar to those reported by Hankinson in Mexican-Americans. While a set of appropiate reference values are obtained, regression equations obtained from the studied group will generate less error in the evaluation of disability in mexican workers.The English version of this paper is available at:
