Investigation and study on the epidemiology of gestational diabetes mellitus in Guizhou

The incidence rate in Guizhou is 18.3%. Older age (especially > 35 years), Han ethnicity, lower education level, higher pre-pregnancy BMI, light physical activity, and higher gravidity are the main risk factors for GDM. Laboratory findings indicate that higher hemoglobin, higher liver function parameters (alanine aminotransferase, aspartate aminotransferase, and direct bilirubin), and lower total protein and albumin are associated with a higher risk of GDM. Blood type A has a higher risk of GDM compared to blood types AB and O.
