Telephone-based cessation service (hereafter Quitline) has been available since 2006 regarding the confidentiality and accessibility of adolescent smokers and it has followed-up abstinence of users with intensive counseling for 1 year.

The baseline information on sociodemographic characteristics, smoking and other health behaviors, nicotine dependency, and motivational factors for quit were collected. Cessation outcome and reason of relapse were identified during the 1 year follow-up of each individual. Multivariate logistic regression was performed to identify associated factors of smoking relapse.
