Útdráttur:Background: Achieving lifelong tobacco abstinence is an important public health goal. Most studies use 1-year
follow-ups, but little is known about how good these are as proxies for long-term and life-long abstinence. Also,
intervention intensity is an important issue for development of efficient and cost-effective cessation treatment
protocols.
The study aims were to assess the long-term effectiveness of a high- and a low-intensity treatment (HIT and LIT) for
smoking cessation and to analyze to what extent 12-month abstinence predicted long-term abstinence.
Methods: 300 smokers attending dental or general health care were randomly assigned to HIT or LIT at the public
dental clinic. Main outcome measures were self-reported point prevalence, continuous abstinence (≥6 months),
and sustained abstinence. The study was a follow-up after 5–8 years of a previously performed 12-month follow-up,
both by postal questionnaires.
Results: Response rate was 85% (n=241) of those still alive and living in Sweden. Abstinence rates were 8% higher
in both programs at the long-term than at the 12-month follow-up. The difference of 7% between HIT and LIT had
not change, being 31% vs. 24% for point prevalence and 26% vs. 19% for 6-month continuous abstinence,
respectively. Significantly more participants in HIT (12%) than in LIT (5%) had been sustained abstinent (p=0.03).
Logistic regression analyses showed that abstinence at 12-month follow-up was a strong predictor for abstinence at
long-term follow-up.
Conclusions: Abstinence at 12-month follow-up is a good predictor for long-term abstinence. The difference in
outcome between HIT and LIT for smoking cessation remains at least 5–8 years after the intervention.
