摘　　要：目的探讨妊娠期糖尿病（GDM）孕妇羊水葡萄糖水平变化与羊水最及新生儿出生体重的关系。方法对255例足月、单胎孕妇，于孕24～28周行50g葡萄糖筛查试验（50g GCT），口服葡萄糖后1h血糖≥7．8mmol／L，且〈10．6mmoL／L者为葡萄糖筛奄阳性，阳性者进一步行75g葡萄糖耐量试验（75gOG＇IT）。根据两项试验结果分为GDM组、妊娠期糖耐量低减（GIGT）组和正常妊娠组，每组85例：分别测定3组孕妇的羊水葡萄糖水平、羊水指数、新牛儿出生体重、孕妇空腹血糖、脐静脉血糖，并进行各指标间相关与回归的统计学分析。结果（1）GDM组羊水葡萄糖水平为（1．30±0．71）mmol／L，明显高于GIGT组的（1．02±0．57）mmol／L和正常妊娠组的（0．90±0．58）mmol／L，分别比较，差异均有统计学意义（P均〈0．01）。（2）GDM组羊水指数为（16．1±4．6）cm，稍高于GIGT组的（14．8±4．3）cm，差异无统计学意义（P〉0．05）；明显高于正常妊娠组的（12．7±3．2）cm，差异有统计学意义（P〈0．01）。（3）GDM组新生儿出生体重为（3612±510）g，低于GIGT组的（3694±490）g，高于正常妊娠组的（3487±458）g，但分别比较，差异均无统计学意义（P〉0．05）。（4）GDM组羊水葡萄糖水平分别与羊水指数（r=0．330，P=0．002）、新生儿出生体重（r=0．347，P=0．001）、孕妇空腹血糖（r=0．589，P〈0．01）、脐静脉血糖（r=0．218，P=0．045）呈正相天关系。GICT组和正常妊娠组羊水葡萄糖水平仅与羊水指数呈正相关关系。（5）GDM组中血糖控制理想孕妇的羊水葡萄糖水平、羊水指数及新生儿出生体重分别为（1．02±0．50）mmol／L、（13．9±4．2）cm及（3497±475）g，血糖控制不理想孕妇分别为（1．92±0．76）mmol／L、（16．4±4．4）cm及（3869±481）g，两者分别比较，差异均有统计学意义（P〈0．01、P〈0．05Objective To investigate the relationship between amniotic fluid glucose concentration, amniotic fluid volume and neonatal birth weight in gestational diabetes mellitus （ GDM）. Methods Two hundred and fifty-five singleton, normal term pregnant women were divided into three groups： GDM, gestational impaired glucose tolerance （GIGT） and normal pregnancy according to the results of a 50 g, 1 hour glucose challenge test （GCT） or of a 75 g oral glucose tolerance test （OGTF）. There were 85 study subjects in each group. All women had GCT at 24 -28 gestational weeks. When they had a positive GCT, in which glucose level was 〉17.8 mmol/L,and 〈 10. 6 mmol/L at 1 hour after oral 50 g glucose, they were required to have a 75 g OGTF. Amniotic fluid glucose concentration （AFG）, amniotic fluid index （AFI）, neonatal birth weight （ NBW）, maternal fasting glucose level （MFG） and umbilical venous glucose level （UvG） were compared in three groups. Statistical analysis of linear regression was done on these indices. Results （ 1 ） The mean AFG in group GDM was （ 1.30 ±0.71 ） mmol/L , which was significantly greater than that in group GIGT, （1.02±0. 57）mmoL/L and that in normal group, （0. 90 ±0. 58）mmol/I, There were significant differences among three groups （P 〈0. 01 ）. （2） In group GDM, the mean AFI was （16. 1 ±4. 6） cm , which was slightly greater than that in group GIGT, （ 14. 8 ± 4. 3 ） cm （ P 〉 0. 05 ）, but was significantly higher than that in normal group, （ 12. 7 ± 3.2 ） em（ P 〈 0. 01 ）. （ 3 ） The NBW of group GDM was （3612 ±510）g, which was lower than that of group GIGT, （3694 ±490）g, and higher than that of normal group, （3487 ±458） g, but there were no significant differences among three groups （P 〉 0. 05）. （4） Among women with GDM, AFG was significantly correlated with AFI （r--0. 330, P =0. 002）, NBW （r=0.347, P=0.001）, MFG （r=0.589, P〈0.01）, and with UvG （r=0.218, P=0.045）.
