Maternal weight gain in women with good pregnancy outcome
1Department of Social and Administrative Health Sciences, University of California, Berkeley.
The most liberal published guidelines for maternal weight gain at term suggest a range of 9-14 kg. In a cohort of 4674 women with good pregnancy outcomes who delivered at the University of California, San Francisco between 1980-1988, the lower end of the currently published weight gain range was relevant, but the upper limit of weight gain was higher. Good pregnancy outcome was defined as a vaginal birth between 37-42 weeks' gestation of a living, singleton infant of appropriate birth weight for gestational age without congenital anomalies, born to a mother who did not experience diabetes or hypertension during pregnancy. Ranges of 12-18 and 10-21 kg described 50 and 80% of the group, respectively. Mean weight gain was associated with maternal pre-pregnancy body mass, parity, and race, with the largest differences observed in overweight and obese women. The results reported here suggest that a wider range of maternal weight gain than is currently recommended is associated with good pregnancy outcome.
