断酒者の自覚的な睡眠障害について

Subjective Sleep Disturbances in Longterm Abstainers

　抄録　アルコール症者の自覚的睡眠状況を検討するために，断酒者300名を対象として睡眠状況に関する自己記入式アンケート調査を実施し，207名の回答（回収率72％）をもとに分析を行い，以下の結果を得た。

　①入眠障害，中途覚醒，早朝覚醒などの睡眠障害が207名中125名（60％）に認められた。②上記125名中の111名（89％）が，benzodiazepine系を中心とする睡眠剤を使用していた。③上記125名中の65名（52％）は睡眠障害が主な原因で再飲酒したくなると回答した。④睡眠障害の出現率は断酒期間3年未満の者に高く，3年以上の断酒者では低かった（それぞれ71％と28％，P＜0.01）。

　We studied the subjective estimate of sleep in 300 alcoholics, using check lists which were given to each patients (207 answerers, 72.3% recovery).

　The results were as follows: 1. A variety of sleep disturbances was seen in 125 alcoholics (60.4%).

　2. Habitual use of several kinds of hypnotics (benzodiazepines, levomepromazine, etc.) was observed in 111 alcoholics (88.8%).

　3. Sixty-five alcoholics out of 125 (52.0%) answered that the sleep disturbances increased their craving for alcoholic beverages.

　4. The alcoholics who had abstained for less than 3 years showed significantly higher incidence of sleep disturbances than those who had abstained for 3 years or more (70.7% and 28.0%, respectively; p＜0.01).

　The present study suggests that sleep disturbance is a serious problem for alcoholics and results in failure in their efforts to abstain from alcohol.
