背景：儿童虐待的怀孕受害者更有可能早产。解释这种关系的机制尚不清楚。当前初步研究的目的是调查瞬间应激和皮质醇是否作为虐待史与妊娠期长度联系的机制。方法：17名女性被纳入研究（35%被虐待）。妇女在怀孕27周和34周完成了两次研究。每次疗程结束后，在两天内每天四次，女性通过短信报告她们的瞬时压力水平，并提供相应的唾液皮质醇样本。通过病历回顾确定妊娠期长度。结果：较高的瞬间应激报告与妊娠期缩短有关。高压力预示着有虐待史的女性皮质醇浓度较低，而没有虐待史的女性皮质醇浓度较高。结论：这项初步研究的结果为理解儿童虐待受害者早产风险增加的机制提供了初步证据。
Background: Pregnant victims of childhood maltreatment are more likely to deliver preterm. The mechanisms explaining this relationship are unclear. The goal of the current pilot study was to investigate whether momentary stress and cortisol serve as mechanisms linking maltreatment history to gestational length.Methods: Seventeen women enrolled in the study (35% maltreated). Women completed two study sessions at 27 and 34 weeks gestation. Following each session, at four times/day over two days, women reported their momentary stress levels by text message and provided corresponding salivary cortisol samples. Gestational length was determined by medical chart review.Results: Higher reports of momentary stress were associated with shortened gestational length. High stress predicted lower cortisol concentrations for women with maltreatment histories but higher concentrations among women without maltreatment.Conclusion: Results from this pilot study provide preliminary evidence for understanding mechanisms explaining increased risk for preterm birth among childhood maltreatment victims.
