Determinants of electronic cigarette use among Finnish adults: Results from a population-based survey

Background: Electronic cigarette (e-cigarette) use is rising in the Western world, but studies from the Nordic countries are lacking. Many countries are implementing policy changes, brought about for example by the 2014 European Tobacco Products Directive, and monitoring e-cigarette use is considered important. The aim of this article is to account for the prevalence of e-cigarette use among the Finnish adult population and to examine correlates of ever use and current use of e-cigarettes prior to some changes in the Finnish regulatory scheme. Methods: A population-based survey was conducted in 2014. A representative random sample (N = 7000) of Finnish people aged 15–69 years was drawn from the Finnish Population Information System. Data were collected by self-administered anonymous online/postal questionnaire. The response rate was 50% (n = 3485). A multinomial logistic regression model was used to estimate the association between e-cigarette use and different explanatory variables. Results: Of all participants, 2% were current and 12% were ever users of e-cigarettes. Younger age and current or previous tobacco use increased the odds for both current and ever use of e-cigarettes when compared with never users. Unemployment and lower education were associated with current e-cigarette use and being a student was associated with ever use of e-cigarettes. Conclusions: The current use of e-cigarettes in the adult population is low in Finland, having at least tried is more common. Both types of e-cigarette use are concentrated to groups considered to be more vulnerable, such as younger people and those with a lower socioeconomic position. Further monitoring of e-cigarette use is needed in view of Finland’s aim to become nicotine and tobacco free by 2030.

Weight concerns as a predictor of smoking cessation according to nicotine dependence: A population-based study

Background: Nicotine-dependent smokers find it difficult to quit smoking. Additionally, smoking-specific weight concerns may affect smoking cessation although the evidence is controversial. We investigated whether smoking-specific weight concerns predict the probability of cessation and, if so, whether the effect varies according to the level of nicotine dependence. Methods: The study was conducted with a population-based sample of 355 adult daily smokers who participated in the baseline examination in 2007 and in the 2014 follow-up. Baseline nicotine dependence was classified as low or high (Fagerström Test for Nicotine Dependence; 0–3 vs. 4–10 points). Within these groups, we examined whether baseline weight concerns predict smoking status (daily, occasional, ex-smoker) at follow-up by using multinomial logistic regression with adjustment for multiple covariates. Results: Among low-dependent participants at baseline, 28.5% had quit smoking, while among highly dependent participants 26.1% had quit smoking. The interaction between weight concerns and nicotine dependence on follow-up smoking status was significant. Among participants with low nicotine dependence per the fully adjusted model, greater weight concerns predicted a lower likelihood of both smoking cessation (relative risk ratio 0.93 [95% CI 0.87–1.00]) and smoking reduction to occasional occurrence (0.89 [95% CI 0.81–0.98]). Weight concerns were not associated with follow-up smoking status among participants with high nicotine dependence. Conclusions: Weight concerns are associated with a smaller likelihood of quitting among smokers with low nicotine dependence. Weight concerns should be addressed in smoking cessation interventions, especially with smokers who have low nicotine dependence.

Social climate on tobacco control in an advanced tobacco control country: A population-based study in Finland

Aims: Finland has implemented a gradually tightening tobacco control policy for decades. Recently the objective of a tobacco-free Finland was introduced. Still, the population’s acceptance of tobacco control policy has not been measured. More knowledge is needed on differences in attitudes and factors associated with tobacco control opinions for future policy-making. Methods: A population-based study with quantitative analysis. Attitudes on smoking and tobacco control policy were assessed within the National FINRISK 2012 Study in Finland involving 25–74-year-old adults (N = 4905). In analyses, smoking status groups were compared. Results: In general, attitudes differed systematically by smoking status. Differences increased or decreased when moving from never smokers to other smoking groups. Similarities in attitudes were found particularly on youth smoking, while differences between smoking groups were notable on statements regarding smoking on balconies and availability of tobacco products. The adjusted analysis showed that smoking status was most strongly associated with attitudes on different tobacco control policy measures. Daily smokers viewed stricter tobacco control policy and workplace smoking bans more negatively than others, though they viewed societal support for quitters and sufficiency of tobacco control policy more positively compared with others. Differences were vast compared with non-smokers, but also occasional smokers differed from daily smokers. Conclusions: Tightening tobacco control and workplace smoking bans were supported by the Finnish adult population, but societal support for quitters to a lesser extent. Attitude change, where smokers are seen as deserving help to quit smoking, is important.
