The amount of ethanol consumed by chronic alcoholics in a Japanese slum area with persistent insomnia (n = 40) and those without it (n = 40) was compared using a questionnaire. For both groups, the present habitual consumption (PHC) of ethanol per day was most frequently between 60 g and 150 g and no difference was observed between the two groups. In contrast, the maximum habitual consumption (MHC) of ethanol per day throughout the alcoholic history was found to be greater for the insomnia patients than the non-insomniacs (p < 0.001). No difference between the groups was found in the kind of alcoholic drink consumed, with sake (Japanese rice wine) being the most popular in both groups. The results suggest that persistent insomnia in alcoholics is related to excessive alcohol intake and persists even when drinking levels have fallen.
通过问卷调查比较了日本一个贫民窟地区患有持续性失眠的慢性酗酒者（n = 40）和未患有持续性失眠的慢性酗酒者（n = 40）的乙醇摄入量。对于两组而言，每日乙醇的当前习惯性摄入量（PHC）大多在60克至150克之间，两组之间未观察到差异。相比之下，发现失眠患者一生中每日乙醇的最大习惯性摄入量（MHC）高于非失眠患者（p < 0.001）。两组在饮用的酒精饮料种类上没有差异，清酒（日本米酒）在两组中都是最受欢迎的。结果表明，酗酒者的持续性失眠与过量饮酒有关，即使饮酒量下降，失眠仍会持续。
