本文观察了糖耐量减低(IGT)孕妇,经严格饮食控制为主处理者71例为第一组,未经严格处理者 69例为第二组,OGTT正常者 72例为第三组。结果OGTT血糖比较除服糖 1小时第一组高于第二组外,差异均无统计学意义,糖化血红蛋白两组比较差异无统计学意义。第三组OGTT结果明显低于IGT两组(P<0.001)。第二组平均出生体重,巨大儿及因其在剖宫产中的比例,妊高征发生率等均增加,与第三组比较差异有统计学意义。孕期复查OGTT病例提示,妊娠期IGT有发展成为GDM的可能。脐血胰岛素一,二两组差异无统计学意义,但第二组高于第三组(P=0.0091)。饮食控制减少了巨大儿发生,但未能明显降低脐血胰岛素水平。
In this study, 71 pregnant women with impaired glucose tolerance (IGT) were selected as the first group, with 69 as the second group without strict treatment and 72 with normal OGTT as the third group. Results Compared with the second group, the blood glucose of OGTT was no significant difference except 1 hour of taking sugar, the difference of glycosylated hemoglobin between the two groups was not statistically significant. The third group of OGTT results were significantly lower than IGT two groups (P <0.001). The second group of average birth weight, macrosomia and its proportion in cesarean section, pregnancy-induced hypertension incidence increased, compared with the third group was statistically significant. Pregnancy review OGTT cases suggest that IGT during pregnancy may develop into GDM. Umbilical cord blood insulin one or two groups, the difference was not statistically significant, but the second group was higher than the third group (P = 0.0091). Diet control reduces macrosomia but does not significantly reduce umbilical cord blood insulin levels.
