U
.S. general population surveys, which do not include patients with severe mental illness who do not live in standard housing arrangements, show that tobacco-smoking behaviors are associated with psychiatric disorders (1). However, very few smoking surveys in the United States or other countries compare persons with severe mental illnesses with the general population (1). This study compared smoking rates among 560 outpatients with severe mental illnesses from facilities in central Kentucky with those among adults from the Kentucky general population. We defined an “ever smoker” as a person 18 years or older who has smoked more than 100 cigarettes during his or her life and a “current smoker” as an ever smoker who currently smokes daily or some days. The prevalence rates of ever smoking, current smoking, and smoking cessation among ever smokers were examined by computing odds ratios (ORs) with 95 percent bootstrap confidence intervals (CIs). A total of 303 patients (54 percent)
were male, 457 (82 percent) were white, 93 (17 percent) were black, and ten (2 percent) were from another race. Clinical diagnoses, made by treating physicians, included schizophrenic disorders (265 patients, or 47 percent), mood disorders (166 patients, or 30 percent) and other diagnoses (129 patients, or 23 percent). Figure 1 shows the percentages of patients and the general population for each smoking category. Further analyses indicated that compared with the general population, patients were three times as likely to ever smoke (OR=3.0, CI=2.4 to 3.6, p< .001), five times as likely to be a current smoker (OR=5.0, CI=4.2 to 5.9, p
