Valoración con tres métodos diferentes de la prevalencia de consumo de tabaco en estudiantes de primer curso de ciencias de la salud de la Universidad de León en 2006

Resumen

Cooximetry does not seem to be a good method for detecting smokers in this population. The cotinine test and the questionnaire are found to agree well, but the internal validity of the questionnaire in comparison to the cotinine test shows a lesser degree of sensitivity than expected. The gold standard criterion used must be revised for a low-dependence population with possible exposure to second-hand smoke.
