摘要
目的研究孕妇主观睡眠质量和客观睡眠质量之间的相关性,分析不同妊娠压力水平下孕妇主观与客观睡眠质量相关性的差异,以更确切地评估孕妇的睡眠质量。方法选取2017年3月-2018年3月松江区323名孕16周的孕妇为研究对象,用匹兹堡睡眠质量指数量表(PSQI)评价近1个月主观睡眠质量,用腕部体动仪记录孕妇连续7 d的客观睡眠质量,用孕妇生活事件量表评价妊娠压力。结果被调查孕妇的PSQI评分平均为6. 39分。腕部体动仪记录得到的睡眠时间、清醒次数、清醒时间和客观睡眠效率都与主观睡眠质量维度、睡眠持续性维度及匹兹堡睡眠质量指数有相关性,相关系数0. 112~0. 173,其中清醒次数与匹兹堡睡眠量表测量结果的相关性最强。相比妊娠压力相对较小的孕妇,妊娠压力较大的孕妇清醒次数和清醒时间与PSQI得分、客观睡眠效率与PSQI得分的线性相关关系不明显。结论在孕妇中,问卷量表和腕部体动仪测得的主观与客观睡眠质量存在较弱的相关性,在反映睡眠质量方面有不同的侧重性。妊娠压力是主观与客观睡眠质量相关性的效应修饰因子,对于妊娠压力大的孕妇,尤其要注意同时观测主观与客观睡眠质量问题。
