A new study from from Northwestern University Feinberg School of Medicine and Greenville Health System University Medical Center reports that participation in CenteringPregnancy was associated with excessive gestational weight gain among normal-weight and overweight women compared with individual prenatal care. CenteringPregnancy was not associated with excessive gestational weight gain in obese women.
The matched retrospective cohort study looked at women who were treated in the Greenville Health System between 2009-2015 and compared their weight gain to Institute of Medicine's 2009 guidelines. The study findings contradict several earlier studies by different research groups that reported either no significant difference in weight gain between these two groups or a slight decrease in weight gain among CenteringPregnancy patients. The authors also state that "the clinical significance of a 2-pound and 4-pound increase in mean weight gain in normal-weight and overweight women, in CenteringPregnancy, is limited..."
The authors go on to discuss the complexity of accounting for all of the potentially confounding factors in such research. The study does not attempt to link these results to those of earlier studies from the Greenville team that show significant improvements in birth outcomes for CenteringPregnancy patients, though presumably many if not most of the patients in those earlier studies are included in the cohorts studied here. It would be interesting to know how maternal weight gain tracks to CenteringPregnancy birth outcomes.
We have tremendous respect for the research team and trust they have brought the same rigorous approach to this study that they have to past studies. We encourage and look forward to future research on all Centering care models.
