An intensive exercise intervention for obese pregnant women did not improve maternal glycemia, but did attenuate excessive gestational weight gain, according to the a single-center, randomized controlled trial published in Obstetrics & Gynecology.
However, excessive gestational weight gain at 36 weeks’ gestation (greater than 9.1 kg) was lower in the exercise group at 22.2%, compared with 43.2% in the control group (P less than .05), of Coombe Women and Infants University Hospital and her coauthors reported.
“Our study may have failed to improve maternal glycemia because the ideal time to begin such a program could be before pregnancy,” the researchers wrote. “Pregnant women who are obese, however, should be advised to exercise because it attenuates excessive gestational weight gain.”
The study was partially funded by Friends of the Coombe, a charity organization. The authors reported having no financial disclosures.
