对在本院产前检查及分娩的1538例孕妇，行口服50g葡萄糖1小时筛查血糖，对其服糖后1小时结果≥7．20mmol／L或疑胎儿大于孕周的477例孕妇进行了口服75g葡萄糖耐量试验，结果显示OGTT异常者随筛查结果增高而增加。糖筛查结果〈7．20mmol／L者，无妊娠期糖尿病（GDM）发生，约占70％以上，可以不做OGTT；血糖结果在7．20～7．79mmol／L者，GDM占3．8％，这些孕妇都具有GDM的高危因素，故此段结果有GDM高危因素者应做OGTT；结果≥7．80mmol／L者应做OGTT。本组还指出了OR值较高的GDM高危因素。
A total of 1538 pregnant women who had antenatal examination and delivery in our hospital were screened for glucose for 1 hour after oral administration of 50 g glucose. The results of one hour after oral administration of sugar were ≥7.20 mmol / L or 477 pregnant women suspected of being fetus larger than gestational age Oral 75g glucose tolerance test, the results showed that abnormal OGTT with the screening results increased. Sugar screening results <7.20mmol / L, no gestational diabetes (GDM) occurred, accounting for more than 70%, you can not do OGTT; blood glucose results in 7.20 ~ 7.79mmol / L, GDM accounted for 3. 8%, these pregnant women have the risk factors of GDM, so the results of the high risk factors for GDM should do OGTT; results ≥ 7.80mmol / L OGTT should be done. The group also pointed out the high risk of GDM risk factors.
