Pregnancy represents a critical time during which women are increasingly susceptible to challenges that can shape maternal health postpartum. Given the increasing number of women who are working through the duration of their pregnancies, in this study, we examine the extent to which both maternal psychological and physical health are influenced by social support received at work during pregnancy. Specifically, we examine 118 pregnant employees’ perceptions of coworker support, supervisor support, and stress over the course of 15 working days. We then link prenatal stress levels with postpartum maternal health outcomes following women’s return to work. At the within-person level, coworker support predicted next-day decreases in stress during pregnancy; however, stress did not predict next-day change in coworker support. There was no relationship between supervisor support and next-day change in stress during pregnancy or vice versa. At the between-person level, an interactive effect between coworker support and supervisor support emerged in predicting prenatal stress, such that women who benefitted from supportive coworkers and supportive supervisors during pregnancy reported the lowest levels of prenatal stress which were, in turn, associated with lower incidence of postpartum depression and quicker recovery times from birth-related injuries. Significant indirect effects suggested that when perceptions of supervisor support were higher (but not lower), coworker support during pregnancy predicted lower incidence of postpartum depression and quicker recovery times through reduced prenatal stress. Taken together, our findings provide novel insight into how specific aspects of the workplace environment may interact to shape maternal psychological and physical health during pregnancy and postpartum.

怀孕是一个关键时期，在此期间，女性越来越容易受到可能影响产后孕产妇健康的挑战。鉴于在整个怀孕期间工作的妇女人数不断增加，在本研究中，我们研究了孕期在工作中获得的社会支持对孕产妇心理和身体健康的影响程度。具体而言，我们调查了 118 名怀孕员工在 15 个工作日内对同事支持、主管支持和压力的看法。然后，我们将产前压力水平与妇女重返工作后的产后孕产妇健康结果联系起来。在个人层面，同事的支持预测了怀孕期间第二天的压力会减少；然而，压力并不能预测第二天同事支持的变化。主管支持与怀孕期间第二天的压力变化之间没有关系，反之亦然。在人际层面，在预测产前压力方面出现了同事支持和主管支持之间的交互作用，例如从支持性同事中受益的女性而在怀孕期间支持监事报道产前应激的最低水平，这是反过来，与生育有关的伤害产后抑郁症和更快的恢复时间的发生率较低。显着的间接影响表明，当对主管支持的看法较高（但并非较低）时，怀孕期间的同事支持可通过减少产前压力预测产后抑郁的发生率较低和恢复时间较快。综上所述，我们的研究结果提供了关于工作环境的特定方面如何相互作用以塑造孕期和产后孕产妇心理和身体健康的新见解。
