To evaluate the usefulness of a fasting plasma glucose (FPG) at 24-28 weeks' gestation to screen for gestational diabetes mellitus (GDM).
The medical records and results of a 75-g 2-h oral glucose tolerance test (OGTT) of 24,854 pregnant women without known pre-GDM attending prenatal clinics in 15 hospitals in China were examined.
FPG cutoff value of 5.1 mmol/L identified 3,149 (12.1%) pregnant women with GDM. FPG cutoff value of 4.4 mmol/L ruled out GDM in 15,369 (38.2%) women. With use of this cutoff point, 12.2% of patients with mild GDM will be missed. The positive predictive value is 0.322, and the negative predictive value is 0.928.
FPG at 24-28 weeks' gestation could be used as a screening test to identify GDM patients in low-resource regions. Women with an FPG between ≥4.4 and ≤5.0 mmol/L would require a 75-g OGTT to diagnose GDM. This would help to avoid approximately one-half (50.3%) of the formal 75-g OGTTs in China.
评估妊娠 24-28 周时的空腹血糖(FPG)在筛查妊娠期糖尿病(GDM)方面的作用。
对中国 15 家医院的 24854 名无已知孕前 GDM 的孕妇的病历和 75g 2 小时口服葡萄糖耐量试验(OGTT)结果进行了检查。
FPG 截断值为 5.1mmol/L 时,可诊断出 3149 名(12.1%)患有 GDM 的孕妇。FPG 截断值为 4.4mmol/L 时,可排除 15369 名(38.2%)孕妇的 GDM。使用该截断点,将错过 12.2%的轻度 GDM 患者。阳性预测值为 0.322,阴性预测值为 0.928。
妊娠 24-28 周时的 FPG 可作为一种筛查试验,用于识别资源匮乏地区的 GDM 患者。FPG 在 4.4mmol/L 至 5.0mmol/L 之间的女性需要进行 75g OGTT 以诊断 GDM。这将有助于避免在中国进行的约一半(50.3%)正式 75g OGTT。
