摘要
[目的]了解先兆早产孕妇分娩孕周的现状并分析分娩孕周的影响因素。[方法]采用前瞻性研究设计。纳入131例因先兆早产住院的孕妇,早产组83例,足月产组48例。采用感知压力量表(Perceived Stress Scale,PSS)和爱丁堡产后抑郁量表(Edinburgh Postpartum Depression Scale,EPDS)进行压力和产前抑郁的调查。并收集入院当天24 h内08:00、16:00和23:00的唾液进行唾液皮质醇(salivary cortisol,SC)检测。采用多重线性回归分析分娩孕周的影响因素。[结果]孕妇总体的分娩孕周为35.3(32.4,37.3)周。83例(63.4%)孕妇发生早产,早产组分娩孕周为33.3(31.5,34.8)周。孕妇总体、早产组和足月产组的PSS得分依次为(21.4±8.0)分、(22.5±7.8)分、(19.5±8.0)分。早产组PSS得分高于足月产组(t=2.128,P=0.035)。孕妇总体、早产组和足月产组的EPDS得分依次为9.0(5.0,13.0)分、12.0(6.0,14.0)分、6.5(4.0,11.0)分。早产组EPDS得分高于足月产组(Z=-2.683,P=0.007)。63名孕妇存在产前抑郁,筛查率为48.1%。多重回归分析结果显示:孕妇23:00 SC、入院孕周、医疗费用支付方式以及宫颈扩张、产次是分娩孕周的影响因素,联合解释变异量为39.2%(调整后为35.8%)。[结论]先兆早产孕妇的压力水平高,产前抑郁普遍存在。孕妇的午夜SC浓度越高,则分娩孕周可能越小。医护人员应密切关注并积极改善孕妇的心理压力和产前抑郁情绪,以帮助孕妇尽可能足月分娩。孕妇的SC对先兆早产者分娩孕周具有潜在的预测价值。
