The percentage of mothers giving birth who received a diagnosis of diabetes during pregnancy (gestational diabetes) increased from 6.0% in 2016 to 8.3% in 2021. Increases in gestational diabetes were seen in each maternal age group, and rates rose steadily with maternal age; in 2021, the rate for mothers aged ≥40 years (15.6%) was nearly six times as high as the rate for mothers aged <20 years (2.7%).
