The purpose of this study was to examine the effects of CenteringPregnancy group prenatal care on breastfeeding outcomes, relative to traditional prenatal care delivered in an individual format.
A quasi-experimental research design was conducted with 794 women receiving prenatal care delivered in a group or individual format at 4 sites in Tennessee. Propensity scores were used to create groups of women statistically matched on background demographics and medical history. Outcomes included breastfeeding at discharge and breastfeeding at postpartum follow-up.
Compared with the matched comparison group of women receiving prenatal care in an individual format, women in CenteringPregnancy group prenatal care had significantly higher odds of any breastfeeding at discharge (odds ratio [OR], 2.08; 95% confidence interval [CI], 1.32-3.26; P < .001). Across the 4 sites, there were no consistent differences in the odds of any breastfeeding at follow-up or exclusive breastfeeding at discharge or postpartum follow-up.
CenteringPregnancy group prenatal care may have beneficial effects on initial rates of breastfeeding relative to individually delivered care. However, there is not sufficient evidence to conclude that CenteringPregnancy group prenatal care has robust effects on exclusive breastfeeding at discharge or postpartum follow-up.
本研究旨在考察与传统个体形式的产前护理相比，集中妊娠小组产前护理对母乳喂养结果的影响。
在田纳西州的 4 个地点，采用准实验研究设计，对接受小组或个体形式产前护理的 794 名妇女进行了研究。使用倾向评分对具有背景人口统计学和病史的妇女进行了统计学匹配的分组。结果包括分娩时的母乳喂养和产后随访时的母乳喂养。
与接受个体形式产前护理的匹配对照组相比，集中妊娠小组产前护理的妇女在分娩时任何母乳喂养的可能性显著更高（优势比[OR]，2.08；95%置信区间[CI]，1.32-3.26；P<.001）。在 4 个地点，在产后随访时任何母乳喂养或完全母乳喂养的可能性均无一致差异。
集中妊娠小组产前护理可能对初始母乳喂养率具有有益影响，与个体提供的护理相比。然而，没有足够的证据得出结论，集中妊娠小组产前护理对产后随访时的完全母乳喂养有明显的影响。
