ABSTRACT
Epidemiological and clinical studies have shown a positive correlation between smoking and psychiatric disorders. To investigate the prevalence of cigarette smoking, 277 psychiatric outpatients with anxiety or depressive disorders (DSM-IV) answered a self-evaluation questionnaire about smoking behavior and were compared with a group of 68 control subjects. The diagnoses (N = 262) were 30.2 percent (N = 79) major depressive disorder, 23.3 percent (N = 61) panic disorder, 15.6 percent (N = 41) social anxiety disorder, 7.3 percent (N = 19) other anxiety disorders, and 23.7 percent (N = 62) comorbidity disorders. Among them, 26.3 percent (N = 69) were smokers, 23.7 percent (N = 62) were former smokers and 50.0 percent (N = 131) were nonsmokers. The prevalence of nicotine dependence among the smokers was 59.0 percent (DSM-IV). The frequency of cigarette smoking did not show any significant difference among the five classes of diagnosis. The social anxiety disorder patients were the heaviest smokers (75.0 percent), with more unsuccessful attempts to stop smoking (89.0 percent). The frequency of former smokers was significantly higher among older subjects and nonsmokers were significantly younger (chi² = 9.13, d.f. = 2, P = 0.01). Our data present some clinical implications suggesting that in our psychiatric outpatient sample with anxiety disorder, major depression and comorbidity (anxiety disorder and major depression), the frequency of cigarette smoking did not differ from the frequency found in the control group or in general population studies. Some specific features of our population (outpatients, anxiety and depressive disorders) might be responsible for these results:
