A final goal of the present study is to estimate the prevalence of sleep apnea in the general population of Japan. As the first step, the detailed questionnaires were sent out to the presumably healthy subjects who underwent regular medical checkups at four hospitals in different cities of Japan. The questionnaires included queries about difficulties in initiating and maintaining sleep, habitual snoring, parasomniac symptoms, excess daytime sleepiness, any present illness, consumptions of cigarettes and alcohol and so on. A total of 3,243 replies were obtained so far (2,029 male and 1,214 female; mean age = 50 years). The results were consistent among the four hospitals, and the prevalences of risk factors were as follows: habitual snoring was reported by 12.8-16.0%, excess daytime sleepiness by 8.1-9.4% and frequent awakenings by 7.3-12.6%, respectively. The prevalence of systemic hypertension ranged from 5.3% to 12.9%. Polysomnographic studies are being performed on the possible cases of sleep apnea who were sorted out by the questionnaires.
本研究的最终目标是估计日本普通人群中睡眠呼吸暂停的患病率。第一步，向在日本不同城市的四家医院接受定期体检的疑似健康受试者发放了详细问卷。问卷内容包括关于入睡和维持睡眠困难、习惯性打鼾、异态睡眠症状、日间过度嗜睡、目前的任何疾病、吸烟和饮酒情况等问题。到目前为止，共收到3243份回复（男性2029份，女性1214份；平均年龄=50岁）。四家医院的结果一致，危险因素的患病率如下：习惯性打鼾的报告率为12.8%-16.0%，日间过度嗜睡的报告率为8.1%-9.4%，频繁觉醒的报告率为7.3%-12.6%。系统性高血压的患病率在5.3%至12.9%之间。正在对通过问卷筛选出的可能患有睡眠呼吸暂停的病例进行多导睡眠图研究。
