[Correlation between carbon-monoxide levels in exhaled air and nicotine-dependence measurements systems (DSM-IV, Fagerström test and ARU-SMQ-9) in adolescent smokers].

Background And Objective: If we are capable of 1) determining the correlation, in young smokers, between carbon-monoxide levels in exhaled air (CO) and carboxihemoblobine (COHb) (cooximetrically determined) and 2) adapting the versions of the nosologic criteria DSM-IV for nicotine-depencence (DSM-IVa), Fagerström Test (FTNDa), and ARU-SMQ-9a Test to adolescents, then we may be able to establish how useful such tests are to measure nicotine-ependences in adolescents. SUBJECTS AND MEHTOD: Cross-sectional, observation-based study carried out in 41 schools. 2,647 students aged 10 to 17 years were surveyed.
