Clinical utility of the Overload Test with 50 g. of Oral Glucose (PSG) is evaluated, in 513 pregnancies with risk factors for diabetes. Of the 933 PSG which were made, 13.7% were positive (limit value: plasma glucose of much less than 150 mg/dl at 1 hour); the test were made after 20 weeks of gestation in 82.8% of the cases. Of the 128 positive PSG, 73 positive Oral Glucose Tolerance Test were obtained (O'Sullivan criteria). The prevalence of gestational diabetes found in this group was 15.2%. There was no difference on the most frequent risk factors (family history, obesity and macrosomia) between the general population in the study and the group of Gestational diabetes.
PSG, because of its easy application, low cost and excellent tolerance is a test which should be included among the prenatal routine test as screening for gestational diabetes in our media.
对513例有糖尿病危险因素的孕妇进行了50克口服葡萄糖负荷试验（PSG）的临床效用评估。在进行的933次PSG中，13.7%呈阳性（限值：1小时时血浆葡萄糖远低于150毫克/分升）；82.8%的病例在妊娠20周后进行了该试验。在128例阳性PSG中，获得了73例口服葡萄糖耐量试验阳性（奥沙利文标准）。该组中发现的妊娠期糖尿病患病率为15.2%。研究中的一般人群与妊娠期糖尿病组之间在最常见的危险因素（家族史、肥胖和巨大儿）方面没有差异。
PSG因其应用简便、成本低且耐受性良好，应作为我们地区妊娠期糖尿病筛查的产前常规检查项目之一。
