睡眠质量与非眩晕性头晕之间的关系:一项基于医院的病例对照研究

2013年4月18日收2013年6月11日收2013年6月11日通信地址Kwang Ik Yang, MD, PhD，顺天香大学医学院，天安医院神经内科，31顺天香6-gil，天安，330-721，韩国电话:+82-41-570-2290传真:+82-41-592-3810 E-mail: neurofan@schmc.ac.kr目的:睡眠质量差会影响白天的功能，引起疲劳和白天过度嗜睡。头晕是常见的主诉之一，可归因于各种医学和神经心理障碍。但睡眠质量差对头晕的影响尚未得到充分研究。我们假设睡眠质量差的患者可能会感到非眩晕性头晕(NVD)。本研究的目的是探讨睡眠质量与NVD发展之间的关系。方法:选取2009年7月1日至2010年6月30日在顺天乡大学天安医院神经内科就诊的NVD患者106例。完成匹兹堡睡眠质量指数(PSQI)、失眠严重程度指数(ISI)、疲劳严重程度指数、Epworth嗜睡量表、睡眠障碍问卷中的睡眠呼吸暂停量表和贝克抑郁量表(BDI)。通过健康筛查中心招募了116名无头晕的对照组，并完成了相同的问卷调查。结果:NVD患者PSQI和ISI评分明显高于对照组(PSQI: 7.7±4.4比5.4±2.6,p<0.001; ISI: 9.7±7.0比6.8±4.4,p<0.001)。在调整了年龄、性别、体重指数和BDI的多重logistic回归分析中，睡眠质量差与NVD显著相关。NVD与PSQI增加1个单位相关的完全校正优势比(OR)为1.15[95%可信区间(CI): 1.04-1.26]。失眠(ISI≥15)与NVD显著相关(OR=4.43, 95% CI: 1.66 ~ 11.81)。结论:本研究提示睡眠质量差与NVD有关。[J]睡眠研究，2013;10:15-19
