Fit mums-to-be are less likely to get diabetes during pregnancy
Researchers at the Harvard School of Public Health in Boston, US, have demonstrated that physical activity before pregnancy can lower the risk of gestational diabetes by up to half. They also found that exercise in early pregnancy cuts the risk by a quarter. Researchers examined studies of 34,929 patients’
activity levels prior to pregnancy, as well as rates of gestational diabetes. Women who did the most physical activity before they got pregnant were 55 per cent less likely to develop gestational diabetes than those doing the least amount of exercise. This benefi t dropped to 24 per cent among those who only started their exercise in early pregnancy. The study was published in Diabetes Care in September 2010.
Research could offer new advice for mums of all fi tness levels
A study is currently underway at John Hopkins University in Baltimore, US, that could lead to revisions in the advice given to pregnant women about exercise. The study is testing women of different levels of
fi tness, all taking exercise based on their ability levels, and monitoring the impact of this exercise on their babies. Around 60 women in their third trimester are taking
part in a treadmill test. The women are only being asked to work to the best of their ability, whether this is walking, jogging or running. Foetuses are examined by ultrasound before and after treadmill work. Over time, the doctors plan to measure the impact of
exercise on the foetuses; to develop new ways to monitor the foetus during exercise, for example wirelessly; and to collect long-term data on the pregnancy outcomes.
