PURPOSE: To investigate depression and stress associated nicotine dependence in healthy smoker.
METHODS: This retrospective study reviewed 1487 subjects to receive health checkup in November 2009. Nicotine dependence was measured as FTND (Fagerstrom test for nicotine dependence). Beck depression inventory, state-trait anxiety inventory, sleep questionnaires, alcohol questionnaires and stress response inventory of Korea version were used.
RESULTS: Of the 1487 subjects reviewed, there were median age of 46 years (interquartile range, 38-53 years) and 918 subjects (62 %) were men. Current smokers, ex-smokers, and non-smokers were 23%, 11 % and 66 %. There were lots of male sex (p< 0.001), college graduate (p< 0.001), and young age (p< 0.001) in current smoker. The scores of stress (21 ±20 vs. 18±20, p< 0.001), state-anxiety (35 ±12 vs. 33±13, p=0.032), sleep questionnaire (47 ±13 vs. 44±15, p< 0.001), and alcohol questionnaire (12 ±7 vs. 5±6, p< 0.001) of current smokers were higher than those of others. However the score of depression and trait anxiety did not showed significant difference between current smoker and the others. Smokers with high nicotine dependence were 148 (43 %) of 342 current smokers. They were many in diabetes (p=0.009), but had not differences in level of education, income, or marriage compared with persons of moderate or low nicotine dependence. The scores of stress (28 ±24 vs. 16±15, p< 0.001), depression (7.7 ±6.1 vs. 5.2±5.1, p< 0.001), state-anxiety (38 ±12 vs. 33±12, p< 0.001), trait-anxiety (39 ±11 vs. 34±11, p< 0.001), and sleep questionnaire (50 ±13 vs. 45±12, p< 0.001) of smokers with high nicotine dependence were higher than those of others.
CONCLUSION: Underlying mental health conditions as well as nicotine dependence is needed to address in understanding of cessation or comorbidity of smoking.
CLINICAL IMPLICATIONS: Smoking cessation.
