RESUMO
OBJECTIVE: To determine the prevalence of cigarette smoking among patients with schizophrenia and to explore their sociodemographic and clinical characteristics. METHOD: A cross-sectional descriptive study of 367 patients with schizophrenia. Instruments administered included sociodemographic questionnaire, Present State Examination: schizophrenia section to confirm schizophrenia diagnosis and Present State Examination: tobacco section to those that smoked. RESULTS: A total of 189 females (51.5%) and 178 (48.5%) males were studied. The mean age of the participants was 34.1 ± 9.94 years. Two hundred and forty-one (65.7%) had never being married. Two hundred and three (55.3%) had secondary school education. A lifetime prevalence of 25.9% and a current smoking rate of 20.4% were reported. Ninety five (53.4%) of the males had smoked at least once in their lifetime. None of the females smoked. Among those that smoked, being unmarried (Ï°² = 6.51, P < 0.01) and unemployed (Ï°² = 5.11, P < 0.02) were associated with prescription of high doses of antipsychotics. Of those that smoked, the managing psychiatrist identified or documented only twenty-five (26.3%) of them (kappa = 0.80, P < 0.00). CONCLUSION: The rate of smoking in Nigerian patients with schizophrenia is considerably less than is reported for their Western counterparts.
