[BDSP. Notice produite par INIST-CNRS EYR0x2La. Diffusion soumise à autorisation]. Objectives. We sought to identify prospective predictors of long-term abstinence versus relapse among individuals who quit smoking as young adults. Methods. Participants from an ongoing longitudinal study of smoking who had quit for at least 1 year between the ages of 18 and 24 years (n=327) were divided into those who later reported not smoking for more than 5 years (long-term abstinence) or reported current smoking, defined as smoking at least monthly (relapse). Logistic regression was used to examine odds ratios (ORs) of prospective predictors of long-term abstinence versus relapse. Results. Overall, 67% of participants maintained long-term abstinence and 33% relapsed. The strongest predictor of avoiding relapse was marrying a nonsmoker (adjusted OR [AOR]=0.07 ; 95% confidence interval [Cl]=0.03,0.21). Other predictors included making 1 lifetime quit attempt (AOR=0.13 ; 95% Cl=0.04,0.44), having as a young adult only 1 parent who smoked (AOR=0.23 ; 95% Cl=0.06,0.93), and working in a completely smoke-free building (AOR=0.13 ; 95% Cl=0.03,0.58). Conclusions. The factors related to smoking in the social environment played the largest role in predicting long-term abstinence versus relapse.
