目的

探讨中、晚孕期补充外源性钙制剂对妊娠结局的影响。

方法

选择2012年1~12月于成都市某三甲妇女儿童专科医院住院分娩的7 908例孕产妇的病历资料为研究对象,并按照外源性钙制剂补充情况,将其分为实验组(n=3 763,补充外源性钙制剂)和对照组(n=4 145,未补充外源性钙制剂)。本研究遵循的程序符合成都市妇女儿童中心医院人体试验委员会所制定的伦理学标准,得到该委员会批准,分组征得受试对象本人的知情同意,并与之签署临床研究知情同意书。比较两组孕妇基本情况和妊娠结局。

结果

两组孕妇基本情况比较,差异均无统计学意义(P>0.05)。实验组孕妇孕期合并症、严重并发症发生率(7.15%和8.11%)均显著低于对照组(9.07%和10.93%),并且差异有统计意义(χ2=24.39,28.46;P<0.05)。实验组新生儿出生体质量显著高于对照组[(3 062±1 051) g vs (2 964±1 230) g],并且其早产和低出生体质量发生率显著低于对照组(5.93% vs 7.99%),两组比较,差异均有统计学意义(t=3.67,χ2=24.36;P<0.05)。

结论

中、晚孕期补充外源性钙制剂对降低孕期合并症、并发症发生率以及增加新生儿体质量、减少早产和低体质量儿具有明显影响。采用小剂量每日多次补充赖氨酸磷酸氢钙可以作为中、晚孕期补充外源性钙制剂的优选策略。

Objective

To evaluate the effects of calcium supplementation during the second and third trimester on pregnancy outcomes.

Methods

From January to December 2012, a total of 7 908 pregnant women were included in the study.They were divided into trial group(n=3 763, intake lysine calcium) and control group(n=4 145, no calcium supplement). The study protocol was approved by the Ethical Review Board of Investigation in Human Being of Chengdu Women and Children' Central Hospital.Informed consent was obtained from each participants.

Results

There were no significant differences between two groups in basic characteristics such as age, examination times before laboring and expenses during delivery hospitalization(P>0.05). The trial group has significantly lower risk of server complications during pregnancy and laboring induced diseases for maternal than those of control group(7.15% vs 9.07%, 8.11% vs 10.93%; χ2=24.39, 28.46; P<0.05). The birth weight in trial group was obviously higher than that of control group[(3 062±1 051) g vs (2 964±1 230) g; t=3.67, P<0.05)], meanwhile, the incidence rate of preterm birth and lower birth weight in trial group were lower than that of control group(5.93% vs 7.99%; χ2=24.36, P<0.05).

Conclusions

Small doses of calcium supplementation during pregnancy is helpful for the outcomes of laboring. It is safe and useful to choose lysine calcium for maternal calcium supplementation during the second and third trimester of pregnancy, which has lower side effects and lower clinical calcium deficiency symptoms during pregnancy.
