Abstract

INTRODUCTION:

We aimed to evaluate the association of exercise with incidence of gestational diabetes mellitus (GDM) and the necessity for GDM treatment.

METHODS:

This was a prospective analysis of women who received prenatal care at Mayo Clinic Rochester. Subjects were surveyed about their exercise habits throughout pregnancy. Clinical data was collected via electronic medical record. Exercise was separated into three categories: no exercise, less than 150 minutes of exercise per week and greater than or equal to 150 minutes of exercise per week.

RESULTS:

512 women with a mean age of 30.5 (SD 4.5) met inclusion criteria, and 43 were diagnosed with GDM (8.4%). GDM patients were older (32.2 v. 30.4, P<.01), had a higher pre-pregnancy BMI (29.9 v. 25.2, P<.01) and were more likely to have a GDM history (P<.01). GDM patients gained less weight (9.5 v. 13.4 kg, P<.01) and were more likely to have a cesarean delivery (P=.02). GDM patients were less likely to achieve the recommended amount of exercise during their pregnancy (P=.03). However, in the overall cohort, amount of exercise during pregnancy was not associated with developing GDM. The amount of exercise during pregnancy was also not significantly associated with the need for GDM treatment.

CONCLUSION:

Although those who developed GDM were less likely to achieve 150 minutes of exercise per week, exercise level was not significantly associated with developing GDM most likely due to low sample size. Further investigation into the role of exercise in prevention of GDM is necessary.
