该研究在日本普通人群中的代表性样本（n=3030）中检查了失眠的患病率和相关性。使用结构化问卷调查，我们发现，在前一个月失眠的总体患病率为21.4%，包括难以启动睡眠（DIS：8.3%），难以维持睡眠（DMS：15.0%）和清晨觉醒（EMA：8.0%）。多元Logistic回归分析显示，年龄较大，失业，缺乏习惯性锻炼，自觉健康状况差，心理压力，无法科普压力与失眠的患病率增加。这些研究结果表明，日本一般人群中失眠的患病率与西方国家的报告相当，失眠与多种心理社会因素有关。
The study examined the prevalence and correlates of insomnia in a representative sample (n=3030) from the general population of Japan. Using a structured questionnaire, we found that the overall prevalence of insomnia during the preceding month was 21.4%, including difficulty initiating sleep (DIS: 8.3%), difficulty maintaining sleep (DMS: 15.0%), and early morning awakening (EMA: 8.0%). Multiple logistic regression analysis showed that older age, being unemployed, lack of habitual exercise, poor perceived health, psychological stress, and being unable to cope with stress were associated with an increased prevalence of insomnia. These findings indicate that the prevalence of insomnia in the general population of Japan is comparable to that reported in Western countries, and that insomnia is associated with multiple psychosocial factors.
