Brief Summary

Smoking is still one of the most important risk factors causing morbidity and mortality in Sweden. Every year, 12,000 Swedish citizens die prematurely from smoking, and smoking is responsible for up to 60% of the inequity in health.

Though the smoking prevalence is relatively low in Sweden in an international context (8% and 10% for men and women respectively in 2016), specific vulnarable groups have a very high prevalence; e.g. about 80% in alcohol and drug abusers. Furthermore, Sweden has a unique high prevalence of snus users and in 2016 the daily use of tobacco was 25% for men and 14% for women. In addition, products such as cigarettes, snus, and e-cigettes are often mixed.

Despite the fact that about a thousand counsellors have been trained in manual-based person-centred tobacco cessation interventions in Sweden, the effectiveness of the interventions remains unknown, as a follow-up on effect of in-person interventions is not systematically collected in Sweden. Therefore, as of today it is not possible, on a national level, to compare the effectiveness of differences in these interventions, providers, or different groups of tobacco users including disadvantaged and vulnerable groups.

In this study the investigators will evaluate the effectiveness of already implemented in-person cessation interventions targeting smoking, use of snus and/or e-cigarettes, focusing on disadvantaged and vulnerable groups of tobacco users. Furthermore, important factors associated with a successful outcome after controlling for confounders will be identified (in relation to programme, patients and setting).

Study Design

• Observational Model Type: COHORT
• Study Time Perspective: PROSPECTIVE

Study Groups

Exposed

Several studies will be performed based on this cohort. I each study the exposed group will be a group of tobacco users evaluatedin the relevant study. This could be a vulnarable group tobacco users such as: users without a job, with short or no education, without permanent housing, diagnosed with mental illness, diagnosed with chronic obstructive pulmonary disease (COPD), undergoing surgery, adolescents, elderly, migrants, or pregnant women.

Intervention Type: BEHAVIORAL

Already implemented in-person (including online meetings) tobacco cessation interventions in Sweden

Unexposed

In each study the unexposed group will consist of tobacco user from the study cohort without the condition examined in the relevant study.
