WASHINGTON — Either too much or too little weight gain during pregnancy could increase the risk of neonatal intensive care unit admission and peripartum complications, according to data presented at the annual meeting of the American College of Obstetricians and Gynecologists.
The highest quintiles of maternal weight gain during pregnancy were significantly associated with rates of NICU admission in a study of 2,784 singleton pregnancies, Dr. Teresa Tam and her colleagues, of Saint Joseph Hospital, Chicago, reported in a poster.
After adjusting for age, delivery method, and prepregnancy weight, among other factors, the medium weight gain quintiles— 22–29 pounds and 30–35 pounds—were associated with the lowest NICU transfer rates of 3.3% and 2.6%, respectively.
A second poster by Dr. Devendra A. Patel of Weill Cornell Medical College, New York, and colleagues found that heavier women had almost twice the rate of maternal and fetal complications as women of normal weight.
Dr. Patel found no fetal complications and 11 peripartum complications among 68 women whose BMI was less than 30 kg/m
