Pregnant with twins? Here are the weight gains recommended by a researcher

A new study conducted by researchers at the University of Pittsburgh sets new guidelines for weight gain in pregnant women who expect twins. Unlike non-partners, the guidelines for twin pregnancies are not always as precise, which is why the doctors at the Graduate School of Public Health have decided to remedy the situation.

The researchers who published their study on Obstetrics & Gynecology analyzed statistical data on 27,723 pregnancies and twin births (with two children) between 2003 and 2013. This data was then compared with those of the mother, in particular with height and weight both before pregnancy and at birth.

They then worked out three upper and lower recommended weight gain limits for three types of pregnant twin women: Underweight or normal, overweight or obesity.

According to the results presented in the press release of the study, there was an increased risk of poor birth results if the weight gain was:

  • Less than 31 pounds or more than 60 pounds in underweight and normal-weight women;
  • Less than 24 pounds or more than 62 pounds in overweight women;
  • Less than 14 pounds or more than 57 pounds for obese women.

“We are not saying that an increase within these weight ranges is necessarily better for the health of the mother and her children, but simply that an increase above or below them poses a greater risk of poor health. Women should talk to their doctors to determine safe weight gain for them,” says Lisa Bodnar, lead author of the study and professor at the University of Pittsburgh.
