Indicator Report - Diabetes: Gestational Diabetes

Why Is This Important?

Gestational diabetes mellitus is defined as having abnormally high blood glucose levels during pregnancy. This abnormality usually disappears after pregnancy, although as many as 5 to 10 percent of women with gestational diabetes may actually have had undiagnosed type 2 diabetes. Women with gestational diabetes tend to have a higher risk of developing diabetes later in life. At least 40 percent of mothers with gestational diabetes will develop diabetes within 20 years. Mothers with gestational diabetes are more likely to have large babies (over 4,000 grams), a risk factor for unelected cesarean section delivery and adverse birth outcomes. Infants born to women with gestational diabetes have a higher risk of developing diabetes and obesity themselves.

The prevalence of gestational diabetes in Utah has risen steadily since 1990, increasing from 1.4 percent to 3.7 percent of birth records.

Data Notes

Prior to 1997, Utah birth certificates did not differentiate between gestational and pre-existing diabetes. Gestational diabetes rates prior to 1997 were estimated. The average percentage of all diabetes births (between 1997 and 2001) that indicated gestational diabetes was applied to previous years to create this estimate.
