The aim of our study was to evaluate the relationship between the nicotine dependance and functional status of patients on smoking cessation program.
In the cross-sectional study, 72 patients (48 females; mean age was 44.1 ± 12.2 years) have filled standardised questionnaire DAL (List of Daily Activities), that consists of 11 questions about physical daily activities. Its score depend of the number of positive answers (from 0 to 11). The lower the score, the better the physical performance and the patients’ functional status. Nicotine dependance was determined by means of standardised Fagestrom test, which scores range from 0 to 10, with a higher score indicating a greater dependance. According to the level of nicotine dependance, we assigned patients in 3 groups: group I (3 patients) - low dependance: scores 0-3; group II (23 patients) - moderate dependance: scores 4-6; group III (46 patients) - high dependance: scores 7-10. Mean smoking duration was 24.8 ± 11.6 years, and mean index pack-years was 34.6 ± 19.3.
Mean DAL scores were 0.67 in group I, 1.04 in group II and 2.93 in group III. Statistically highly significant difference between the average DAL scores with regard to the patient groups was established by means of ANOVA (F = 5.39, p = 0.007). Pearson’s coefficient of linear correlation also showed a statistically highly significant correlation between the values of DAL scores and the Fagestrom test scores (r = 0.371, p = 0.001).
The functional status in smokers, that could be well determined by the DAL questionnaire, strongly reflects their nicotine dependance as assessed by means of the Fagestrom test.
The functional status of smokers could be successfully used in clinical research and practice as an outcome in smoking cessation programs.
