Exercise may cut gestational diabetes risk in obese women
Obese women are at increased risk of complications during pregnancy, the most common of which are gestational diabetes, high blood pressure, a large increase in weight as well as pre-eclampsia.
“It’s important to reduce obesity-related pregnancy complications because they can have long-term consequences for both the mother and her child,” said a researcher from the Norwegian University of Science and Technology (NTNU) in Trondheim, Norway.
Obese mothers are also at an increased risk of needing a caesarean section and giving birth to large babies. These complications can have a great impact on the health of both mother and child, not just during pregnancy, but also later in life, the researchers said. The findings showed that the amount of exercise needed to reduce the risk of gestational diabetes is not very high.
“That meant that even a little training during pregnancy can be beneficial,” said Kirsti Krohn Garnæs, doctoral candidate at NTNU. Further, women who followed the exercise regimen also showed lower blood pressure towards the end of their pregnancy.
Women in the exercise group were invited to three weekly supervised sessions of 60 minutes throughout the course of their pregnancy.
The training consisted of 35 minutes of moderate intensity treadmill walking and 25 minutes of strength training. The control group was given standard prenatal care. Of these, only two in the exercise group versus nine in the control group developed gestational diabetes.
