| Summary: | Introduction
The study aimed to identify predictors associated with long-term
tobacco cessation at 12-month follow-up among users of the National Smoking
Cessation Services (NSCS) in Korea.
Methods
To measure the long-term effect of NSCS delivery, the target sample
size of 5167 adult smokers registered in the NSCS in 2018 was enrolled with
proportional random sampling. A multiple logistic regression analysis (crude,
adjusted) was performed to identify the changes in smoking status at the 12-month
follow-up after the last NSCS enrollment and the potential factors associated with
changes in smoking status.
Results
The response rate to reach the number of subjects targeted was 22.4%. A
total of 41.2% of the tobacco users enrolled had successfully quit at baseline, and
the 7-day point prevalence of tobacco cessation at the follow-up at 12 months,
via a telephone survey, was 34.4%. Factors positively associated with cessation
at the 12-month follow-up were longer experience with tobacco abstinence
and additional quitting attempts with or without NSCS enrollment, although
every additional quit attempt with NSCS use had a better outcome. In addition,
having a successful quit outcome with NSCS use at the baseline and having more
satisfaction with the service of professional counseling or incentives than others
provided by NSCS, increased cessation at follow-up after adjustment of other
factors considered.
Conclusions
In addition to multiple quitting attempts, longer experience with
tobacco abstinence, and additional enrollment in NSCS, the service experience,
and satisfaction with the content that NSCS offered, might improve the lasting
success of abstinence. These results might be considered to improve the contents
and protocols of the NSCS for better outcomes.
