女性覚せい剤乱用者における摂食障害の合併について（第3報）—摂食障害を伴う女性アルコール乱用者との比較

A Clinical Study of Comorbid Eating Disorders in Female Methamphetamine Abusers, Third report: In comparison with female alcohol abusers with eating disorders

【抄録】　ともに摂食障害を合併する女性覚せい剤乱用者（MAP群）21例と女性アルコール乱用者（AL群）16例を比較検討した。MAP群はAL群に比べ，低学歴者や補導逮捕経験者が多く，覚せい剤乱用者独特の生活背景を持っていた。また，摂食障害先行型のMAP群，後発したMAP群，AL群の比較では，摂食障害先行型のMAP群とAL群は摂食障害の症状・病型が共通して多彩であり，後発型のMAP群とは異なる特徴を呈した。AL群の大半が摂食障害を先行発症し，罹病期間が長いことによるといえた。しかし，先行型のMAP群はAL群より窃盗・盗食と手首自傷が多く，AL群は先行型のMAP群より不食が多く，MAP群の衝動的傾向が推測された。

　We retrospectively studied the clinical features of female methamphetamine (MAP) abusers with eating disorders (ED) and compared them with female alcohol (AL) abusers with ED. Of the female MAP abusers with ED and the female AL abusers with ED who had had their first consultation at the Kanagawa Psychiatric Center, Serigaya Hospital from June 1997 to July 1999, 21 female MAP abusers with ED (group MAP) and 16 female AL abusers with ED (group AL) were selected to participate in the study. The clinical characteristics of the two groups were compared

　The results were as follows:

　1. The group MAP was significantly younger, and had significantly lower education and more criminal records than the group AL.

　2. In the group MAP, the onset of ED was significantly earlier than in the group AL.

　The members of group MAP were classified into group MAP I with precedence of ED onset (13 cases) and group MAP II with precedence of MAP abuse onset (8 cases). The group MAP I and the group MAP II were compared with the group AL with regard to their symptoms of ED.

　The results were as follows:

　3. Although the group MAP II was significantly different from the other two groups in the subtypes and symptoms of ED (because of lack of anorexia nervosa, binge eating and purging type and anorexic episodes), the group MAP I had a lot in common with the group AL.

　4. The group MAP I tended to have significantly less anorexic episodes than the group AL. However, the group MAP I tended to have significantly more impulsive behavior such as stealing and wrist cutting episodes than the group AL.

　Based on these results, we considered that the group MAP had life backgrounds and antisocial tendencies similar to those which MAP abusers have already been reported to have in Japan, and we speculated about the fact that the group MAP I, because of their primary ED onset preceding substance abuse, was more impulsive than the group AL although both groups had similar subtypes of ED.
