Activity Keeps Diabetes at Bay During Pregnancy
posted 04/22/04
Women who are physically active seem to lower their odds of
developing diabetes when they become pregnant.
That comes from a study by Dr. Jennifer C. Dempsey, of the
Swedish Medical Center in Seattle, and colleagues. They examined recreational
physical activity in the year before and during pregnancy among 909 non-diabetic
women without high blood pressure.
According to the team's report in the American Journal of Epidemiology, women
who engaged in any physical activity during the year prior to their pregnancy
had a 56 percent reduced risk of pregnancy-related diabetes compared with
inactive women.
Women who spent at least 4.2 hours per week participating in physical activity
had a 76 percent reduction in risk.
A total of 615 women (67.7 percent) reported participating in physical activity
during pregnancy. These women were 31 percent less likely to develop gestational
diabetes.
The team reports that 576 patients (63.4 percent) reported physical activity
during both the year before and during pregnancy. Compared with the inactive
group, this group had a 69 percent reduced risk, after taking into account the
women's age, race, and pre-pregnancy body weight.
"Concerns remain about the paucity of empirical evidence regarding physical
activity associated with optimal pregnancy outcomes," Dempsey's team notes.
"Randomized lifestyle intervention trials and larger cohort studies are
necessary to confirm our findings."
