Success of a smoking cessation programme in smoking behaviour of chronic periodontitis patients and identification of predictors of motivation for smoking cessation - a pilot study.

BACKGROUND: The primary goal of this pilot study was to evaluate the success of a smoking cessation programme on smoking behaviour of patients with chronic periodontitis. Secondary goals were to identify the prevalence of smoking among them, predictors of motivation for smoking cessation and for successful nicotine abstinence. METHODS: Smokers suffering from chronic periodontitis were offered cognitive behavioural group therapy of 10 once-weekly sessions. Smoking is reduced stepwise and complete cessation is to be achieved by the sixth session. Sociodemographic data, history of smoking and motivation for smoking cessation, subjective health status, and questionnaires on anxiety, depression, control beliefs and coping with stress were completed at study entry. Smoking behaviour was assessed at the end of the group programme and 3 months thereafter. RESULTS: Of 469 patients with periodontitis, 59 (12.6%) were smokers; 30 (50.6%) patients participated in the smoking cessation programme. Participants smoked more cigarettes/day (P = 0.03, 95% CI: -17.9/-0.89) and subjectively assessed their health as being worse than non-participants (P = 0.09, 95% CI: -0.16/2.15). In SPQ, non-participants showed more trivialization (P = 0.014, 95% CI: 0.59/4.94). Complete data were available for 15 group participants: six patients were smoke-free after 10 weeks and five after 18 weeks (33.3%); two patients had reduced their cigarette consumption by half. At the start of the programme, less successful participants showed a tendency to higher depression in HADS (P = 0.085, 95% CI: -5.25/5.76) and were more inclined to seek substitute satisfaction (P = 0.034, 95% CI: 3.24/11.23). CONCLUSION: The rate of success in this study was comparable with other studies. More research with larger samples is needed for confirming these observations.
