HealthDay News — As many as one in 10 pregnant patients in the United States develop gestational diabetes, according to research from the CDC.

“Although the true prevalence of GDM is unknown, GDM is estimated to affect 1% to 14% of pregnancies in the United States annually, depending on the population studied and the diagnostic tests used,” Carla DeSisto, MPH, and colleagues from the CDC wrote.

To compare gestational diabetes rates from 2007 to 2009 with 2009 to 2010, investigators used the Pregnancy Risk Assessment Monitoring System questionnaire as well as state birth certificate records.

The prevalence of gestational diabetes is between 4.6% and 9.2% of all pregnancies, indicated the inspectors. The incidence was found to vary by geographical area: Wyoming and Utah had the lowest rates of gestational diabetes, and New York City and Rhode Island had the highest. Most of the state by state difference appears to be related to obesity levels, according to the study authors.

“GDM is a significant public health concern because of its long-term implications for maternal and child health,” concluded researchers. “This study provides additional information about prevalence of GDM, which is important for understanding the future burden of related diseases, most notably type 2 diabetes, and related health care costs.”
