Group Prenatal Care and Gestational Weight Gain

Obstet Gynecol; ePub 2017 Mar 6; Kominiarek, et al

Women in group prenatal care experienced excessive gestational weight gain when compared with women in individual prenatal care, a recent study found. The retrospective cohort study compared rate of gestational weight gain among women in group prenatal care from 2009 to 2015 with that of women in individual prenatal care. Researchers found:

  • Women in group prenatal care (n=2,117) were younger and more commonly non-Hispanic black, nulliparous, and without gestational diabetes.
  • Women in group prenatal care more commonly exceeded the weight gain goals (55% vs 48%).
  • The differences in gestational weight gain were concentrated among normal-weight and overweight women.
  • Race-ethnicity, parity, education, and tobacco use increased the odds for excessive gestational weight gain among normal-weight and overweight women.
