HealthDay News — From 2016 to 2021, there was an increase in prepregnancy diabetes mellitus, with an overall rate of 10.9 per 1000 births in 2021, according to the National Vital Statistics Reports, a publication from the US Centers for Disease Control and Prevention.

Elizabeth C.W. Gregory, MPH, and Danielle M. Ely, PhD, from the National Center for Health Statistics in Hyattsville, Maryland, present data on trends in prepregnancy diabetes mellitus in mothers giving birth in the United States between 2016 and 2021. Rates were presented by maternal race and Hispanic origin, age, body mass index, and state of residence.

The researchers found that the overall prepregnancy diabetes mellitus rate was 10.9 per 1000 births among mothers giving birth in 2021, representing an increase of 27% from 8.6 in 2016. The prepregnancy diabetes mellitus rate varied by maternal race and Hispanic origin in 2021, from 8.7 for White non-Hispanic mothers to 28.6 for American Indian or Alaska Native non-Hispanic mothers. There was an increase noted in the prepregnancy diabetes mellitus rate with increasing maternal age and prepregnancy body mass index. The prepregnancy diabetes mellitus rate was lower than 9.0 in 4 states (Wyoming, Hawaii, Utah, and Colorado), and was 15.0 or higher in 3 states (Tennessee, Vermont, and New Mexico).
