Using a multidimensional approach to measure stress, this study prospectively examined the influence of maternal stress, social support and coping styles on labor/delivery complications and infant birth weight. Beginning in the third month of pregnancy, stress was assessed monthly. In each trimester, data on social support, coping strategies, lifestyle behaviors and pregnancy progress were collected. One month following delivery, information on labor, delivery and infant status was obtained. The final sample consisted of 80 women. The results demonstrated that women who experienced greater stress during pregnancy had a more difficult labor/delivery, even after controlling for parity. Younger maternal age was also linked with intrapartum complications. Perceived prenatal social support emerged as a predictor of infant birth weight. Women who reported less satisfaction with their social support in the second trimester gave birth to infants of lower birth weight. The results suggest an association between specific psychosocial variables and negative birth outcomes.
本研究采用多维方法测量压力，前瞻性地考察了母亲压力、社会支持和应对方式对分娩并发症及婴儿出生体重的影响。从怀孕第三个月开始，每月评估一次压力。在每个孕期，收集有关社会支持、应对策略、生活方式行为和妊娠进展的数据。分娩后一个月，获取有关分娩、接生和婴儿状况的信息。最终样本包括80名女性。结果表明，即使在控制了产次之后，孕期经历较大压力的女性分娩过程也更困难。产妇年龄较小也与产时并发症有关。感知到的产前社会支持成为婴儿出生体重的一个预测因素。在孕中期报告对社会支持满意度较低的女性所生婴儿出生体重较低。结果表明特定心理社会变量与不良出生结局之间存在关联。
