Objective: To explore the relation of nonmanual workers' subhealth and sleep in metropolises. Method: Subhealth questionnaires and lifestyle questionnaires were designed and edited. More than 4000 subhealth questionnaires were issued to nonmanual workers(civil servants, administrative leader, scientific researchers, enterprise administrators, common administrative staff, teacher, physicians, etc) in Guangzhou, meanwhile lifestyle questionnaires were also handed out to 1823 informants. The relations of lifestyle and subhealth incidence as well as subhealth type were analyzed. Result: Subhealth incidence of people with actual sleep was obviously higher than that of people with actual sleep for 6-8 hours; the scores of subhealth people with sleep less than 6 hours and subhealth rank were higher than the people with sleep for 6-8 hours, and there was significant relativity between insufficient sleep and the incidence of clinical manifestation including sleep disorder, memory declining, mental strains, reacting slowly, and tension of family members, etc. Conclusion: Insufficient sleep is an important impact factor in subhealth incidence of nonmanual workers in metropolises.%目的:探讨大型城市非体力劳动者亚健康发生与其睡眠时间两者之间的关系.方法:通过设计、编制亚健康调查问卷和生活方式调查问卷,对广州市非体力劳动者(公务员及行政领导、科研人员、企业管理人员、一般管理人员、教师、医生等)发放42000 余份亚健康调查问卷,其中对12823 位被调查者同时发放了生活方式调查问卷.分析生活方式与亚健康发生率的关系及亚健康类型.结果:每天实际睡眠时间小于6 小时的人群发生亚健康的比例明显高于睡眠6～8 小时人群;每天实际睡眠时间小于6 小时的亚健康人群得分及亚健康等级较睡眠时间6～8 小时的人群高,且睡眠时间不足与亚健康临床表现中的睡眠紊乱、记忆力下降、精神紧张、反应迟钝、家庭成员关系紧张等的发生概率之间有显著相关性.结论:睡眠时间不足是大型城市非体力劳动者亚健康发生中一项重要影响因素.
