个体化营养膳食治疗对葡萄糖筛查异常孕妇妊娠结局的影响

The Effect of Individual Nutritional Therapy on Pregnancy Outcomes among Pregnant with Abnormal Glucose Challenge Test

目的探讨个体化营养膳食治疗对糖筛查异常孕妇妊娠结局的作用和意义。方法采用前瞻性随机对照研究，将孕24～28周、50g糖筛查异常而75g口服糖耐量试验正常的100例孕妇分为l、2两组各50例，1组除孕期常规营养宣教外，制定个体化营养膳食计划实施管理干预；2组只进行孕期常规营养宣教。比较两组的妊娠结局。结果实施管理干预后，1组平均出生体质量、大于胎龄儿发生率、平均体质量增加量明显低于2组，差异有统计学意义（P〈0．05）；而两组剖宫产率、早产率比较无统计学意义（P〉0．05）。结论在对糖筛查异常而糖耐量正常的孕妇管理干预过程中，合理的个体化营养膳食治疗对改善其妊娠结局有较好的临床效果。

Objective To examine the effect of individual nutritional therapy on pregnancy outcomes among patients with abnormal glucose test. Methods A total of 100 patients with positive 50 g GCT and negative 75 g OGTT between 24 and 28 weeks＇ gestation were divided into group 1 and group 2 according to prospective randomized controlled study. 50 patients in group 1 were given a individual nutritional diet and group 2 with 50 patients only were given a routine diet. Pregnancy outcomes were compared. Results After management intervention, there were significant differences in birth weight, number of large for gestational age babies, total maternal weight gain during pregnancy（P〈0.05）. While there were no significant differences between the groups in cesarean rate, preterm rate（P〉0.05）.Conelusions In the management of patients with positive 50 g GCT and negative 75g OGTT, the proper individual nutritional theraoy has better pregnancy outcomes.
