Key Factors in Smoking Cessation Intervention Among 15-16-Year-Olds

The authors aimed to investigate factors associated with smoking cessation among adolescents after tobacco intervention. They examined smokers (n = 127) from one birth cohort (n = 545) in the city of Kotka in Finland. These smokers were randomized in 3 intervention groups the dentist (n = 44) and the school nurse (n = 42 groups), and a control group (n = 39). After 2 months, the authors sent a follow-up questionnaire to the initial smokers to find out who had quit. The authors found that those whose best friend was a nonsmoker were more likely to stop smoking (relative risk RR 7.0 95% Cl 4.6-10.7). Moreover, the nicotine-dependent participants (measured according to the Fagerström Test for Nicotine Dependence 36 Heatherton, T F, Kozlowski, L T, Frecker, R C and Fagerström, K-O. 1991. The Fagerström Test for Nicotine Dependence: A revision of the Fagerström Tolerance Questionnaire. Br J Addict, 86: 1119–1127. [Crossref], [PubMed] , [Google Scholar]) were less likely to stop (RR 0.1 95% Cl 0.08–0.11) compared to non-nicotine dependent participants. Last, of the diurnal types, the morning types found it easier to quit smoking than the evening types (RR 2.2 95% Cl 1.4–3.6). Thus, the authors concluded that the best friend''s influence, nicotine dependence, and diurnal type could be taken more into account in individual counseling on smoking cessation.
