The 13th World Conference on Tobacco OR Health

Objective: To evaluate the effectiveness of a MIGT for smoking cessation in a Latin American Country.

Methods: Voluntary smokers willing to quit, who completed the first individual appointment in the MIGT were included. MIGT is an ambulatory program with a group cognitive behavioral approach, pharmacotherapy and professional and social support skills. The program is composed by 6 weekly sessions, (2 hours each) preceded by 2 individual evaluations. A special tobacco medical chart was designed to record information Outcome measures: Smoking abstinence was reported as prevalence abstinence at one year of the quit date, and breath Carbon Monoxide monitoring We developed a multi-regression model to explore predictors of success.

Results: 437 smokers subjects (59.3% women) willing to quit who were admitted at the first visit of MIGT. Mean age was 48.6 (SD 13.9). Mean number of daily cigarette consumption was 25 (SD 13) Mean FS was 5.6 (SD 2.4). ARU showed the highest mean score in the nicotine sedative effect 6.8 (SD 2.1) . 284 patients (63%) had a complete follow-up at one year. The 37% population without follow-up complete data at one year (abstinence reported and breath CO measurement), were considered smokers. 101 patients (23.7%) were abstinent at one year. In the multivariate analysis the FS and the sedative effect of nicotine in the ARU score were predictors of relapse.
