The search for predictors of failure or success specific to a population with special characteristics, such as Brazilians, should be the first step in the development of SCP national. We evaluated the demographic characteristics and factors influencing the failure or success of quitting among participants in a SCP. This retrospective study was conducted from 2005-2009 in a SCP based on cognitive behavioral treatment associated or not with medication therapy consisted in 20 meetings during 12 months. After that the individuals were invited to answer a socio-economic questionnaire by telephone. A total of 158 individuals were included in this study and 65 agreed to answer a socio-economic questionnaire (aged=49±10, pack-years index=35±24, women=63%). Regarding education level: 50% had primary education, 29% had high school and 21% had university education. Accordance with socio-economic questionnaire 14% of the individuals were at class A2, 21% at class B2, 54% at class C and 11% at class D. After the fourth meeting 47,7% of individuals attempt to quit but only 32% of this group remained abstinent after the end of the SCP. Thereby the total quit rate at 12 months was 15%. The failure in smoking cessation at the end of 12 months was increased in individuals from social class C (p<0.05) and in individual with higher attempts to quit before start the program (p<0.05). Quitting smoking was significantly associated with the outcome and previous attempts to quit. Socio-economic factors should be considerate in the development of smoking cessation intervention in national programs.
