[目的]探讨围产期早期保健及营养指导对妊娠期糖尿病(GDM)及早产的预防价值.[方法]选择2016 年 7 月至 2018 年 3 月在本院进行产检并最终在本院分娩的 109 例孕妇,按照随机数表法分为观察组(5 1 例)和对照组(5 8 例).对照组孕妇在孕产期间接受常规化的保健宣教和健康指导,观察组孕妇则在上述基础上实行围产期早期保健及相应的营养指导,比较两组临床疗效,分析围产期早期保健及营养指导对GDM及早产发生的预防价值.[结果]两组的孕前体质量指数(BMI)比较差异无统计学意义(P >0.05 ),观察组分娩时BMI及孕期体质量增加幅度明显低于对照组,其差异有统计学意义(P 0.05);观察组孕前和分娩时 FPG、2hPG和 HbA1C 水平比较未见明显变化(P >0.05);对照组分娩时 FPG、2hPG 和HbA1C水平明显高于孕前(P 0.05 );the levels of FPG,2hPG and HbA1 C during delivery in the control group were significantly higher than those before pregnancy(P <0.05).The incidence of GDM and premature infants in the observation group were 3.45% and 3.45% respectively,which were significantly low-er than those in the control group (1 9.6 1 % and 21 .5 7%,respectively).The difference between the two groups was statistically significant (P <0.05).[Conclusion]Early health care and nutritional guidance during perinatal period can effectively control BMI and blood sugar level of pregnant women,thus effectively prevent and re-duce pregnancy complications such as GDM and adverse pregnancy outcomes such as premature infants.
