A Reseach on Smoking among Psychiatric Patients : Comparison of Smoking Attitude between Patients with Schizophrenia and Manic Depressive Psychosis

精神神経科, 入院または通院中の男性105名, 女性130名の235名を対象として, 習慣的喫煙の有無を性別, 疾患別に検討したところ, 精神疾患患者の喫煙率は, 男性74.3%女性269%であった.分裂病と躁うつ病群間に喫煙率は, 性差を考慮しても差はなかった.さらに分裂病(n=39)と躁うつ病(n=19), 58名の喫煙患者に対して, 喫煙の動機, 病歴, ハロペリドール投与量, 喫煙本数, ニコチン摂取量, およびタバコ依存症スクリーニング質問表(TDS)を用いてタバコ依存度を比較したところ, 分裂病群と躁うつ病群には喫煙の動機に差があった.喫煙の動機を気持ちが休まるとする分裂病群は躁うつ病群に比べて有意に多く, 手持ちぶさたとする躁うつ病群は分裂病群に比べて有意に多かった.また分裂病群は躁うつ病群に比べてハロペリドール投与量, ニコチン摂取量が有意に多かった.分裂病群と躁うつ病群のタバコ依存度には差がなかった.We studied the habit of smoking in 235 psychiatric inpatients and/or outpatients (105 males and 130 females) in Toyama city focusing on the motivation of smoking, and relation between smoking and daily dose of haroperidole, a representative major antipsychaitric drug. By careful readings of the medical records, the rate of smokers were calculated as 74.3% and 26.4% in male and female patients, respectively. There were no significant differences in these values between the schizophrenia and manic depressive psychosis groups under consideration of gender. When selected 58 psychiatric patients with smoking (39 schizophrenia and 19 manic depressive psychosis) were further examined, it has been clearly demonstrated that there is a significant difference in the motivation of smoking, but not in tabacco dependency screening scores between the schizophrenia and manic depressive psychosis groups. In addition, both daily haroperidol and nicotin doses were significantly higher in the former than the latter groups. These findings suggest that psychopathological antagonistic actions of nicotin against haroperidole might affect at least in part on the persistence of the habit of smoking
