[The comparison of nicotine replacement therapy and behavioral education in smoking cessation: a study of naturalistic follow-up].

In this study, we aimed to compare quitting smoking rates after behavioral education (BE) and/or nicotine replacement therapy (NRT). 610 patients applied between October 1999-April 2002 have been acknowledged and evaluated by a questionnaire including demographic variables, smoking history, smoking habits and attitudes, motivation; biochemical assay and spirometric measures were examined. One-year follow-up results and demographic variables of patients who recruited to treatment (n= 435) were analyzed by chi-square, Student-t test, one-way ANOVA and post-hoc tests.
