A pilot community-based screening program for gestational diabetes

A pilot community-based screening program for gestational diabetes has been in operation in Cleveland, Ohio, since April 1, 1977. A socioeconomic and racially heterogeneous group of pregnant women are being routinely tested at approximately 24-28 wk of gestation by a capillary whole blood glucose determination, 2-h after a 75-g oral challenge. The results of the first 2225 screenings are analyzed in terms of the variables of maternal race, age, and stage of gestation. The overall incidence of positive screenings (≥ 120 mg/dl) is shown to be 11.5%, with significantly more positive tests among the whites than the nonwhites. Follow-up oral glucose tolerance testing results in an overall detection rate for abnormal carbohydrate metabolism of 3.1%. The data suggest that a 2-h screening procedure is more efficient than a 1-h procedure in that fewer confirmatory glucose tolerance tests need to be performed in order to yield this rate of detection. It may soon be feasible to introduce such a program on a wider community basis in concert with regionalized perinatal care.
