Group Prenatal Care Reduces Risk of Preterm Birth and Low Birth Weight: A Matched Cohort Study.

Group prenatal care is a promising strategy to improve perinatal outcomes.

We examined the impact of group prenatal care on preterm birth and low birth weight in a large metropolitan hospital, accounting for patient adherence, over an 8.5-year period.
