CenteringPregnancy (CP) has been expected to produce beneficial outcomes for women and their infants. However, previous studies paid little attention to testing variations in CP's effects across women from different demographic groups. This study aimed to test how multiple demographic factors (obesity, race, ethnicity, marital status and socioeconomic status) moderate CP's effects on health outcomes.
This study employed a quasi-experimental design. De-identified hospital birth data were collected from 216 CP participants and 1159 non-CP participants. We estimated the average treatment effect of CP on outcome variables as a baseline. Then we estimated the average marginal effect of CP by adding each of the moderating variables in regression adjustment models.
CP produced salutary effects among those who were obese or overweight and unmarried as well as women with lower socioeconomic status. These salutary effects were also strengthened as maternal age increased. However, CP was ineffective for Hispanic/Latinx women.
CP produced more beneficial health outcomes for high-risk women such as obese, unmarried women and those with lower socioeconomic status. These are meaningful findings from a public health perspective.
围产期集中护理（CenteringPregnancy，CP）有望为妇女及其婴儿带来有益的结果。然而，以前的研究很少关注测试 CP 对来自不同人群的女性的效果的变化。本研究旨在测试多种人口统计学因素（肥胖、种族、民族、婚姻状况和社会经济地位）如何调节 CP 对健康结果的影响。
本研究采用准实验设计。从 216 名 CP 参与者和 1159 名非 CP 参与者中收集了去识别的医院分娩数据。我们估计了 CP 对结果变量的平均处理效应作为基线。然后，我们通过在回归调整模型中添加每个调节变量来估计 CP 的平均边际效应。
CP 对肥胖或超重、未婚以及社会经济地位较低的妇女产生了有益的效果。这些有益的效果随着产妇年龄的增加而增强。然而，CP 对西班牙裔/拉丁裔妇女无效。
CP 为高风险妇女（如肥胖、未婚妇女和社会经济地位较低的妇女）带来了更有益的健康结果。从公共卫生的角度来看，这些发现具有重要意义。
