BACKGROUND: In 1997 the American Diabetes Association (ADA), recommended a change in the screening and diagnosis criteria: no screening for low risk patients and adoption of the diagnosis criteria by Carpenter and Coustan.
We do not know the incidence in our population or whether we are or not a high-risk group for diabetes.
METHODS: A descriptive series was carried out from August 1999 to July 2000. Pregnant women who had prenatal checkups in the central CAA of Medellín's SSI; they underwent to screening with the O'Sullivan test between 24 - 28 gestational weeks, and the tolerance oral test for those who needed it.
A phone survey was done after birth for getting the maternal and neonatal results.
RESULTS: 1726 patients were evaluated. An incidence of 1.43% was found and increased to 2.03% when the new criteria were applied.
The positive predictive value of the screening test was determined, demonstrating that it was not diagnostic with any value.
20.5% of infants presented macrosomia. 13% in the NDDG criterion group and 40% in the ADA criterion group.
CONCLUSION: In this group of patients, a low incidence of gestational diabetes was found compared with other population, we did not achieve to demonstrate that adopting the new criteria improved the maternal and neonatal prognosis; it should be carried out new surveys which permit a better population selection who are going to undergo the screening test for optimizing resources.
