Universal screening for GDM was
recommended in 1985. According to this recommendation, all pregnant women,
regardless of the presence of risk factors should be screened for GDM.
In 1999, the American Diabetes Association changed the previous
recommendations from universal screening to high risk groups screening. High
risk women include those age > 25, overweight
before pregnancy, members of an ethnic group with a high prevalence of diabetes,
having first relatives with diabetes, history of abnormal glucose tolerance and
history of poor obstetric outcome.
