孕期体重增长与新生儿出生体重相关性分析(1)
[摘要] 目的 分析孕妇孕期体重增长与新生儿出生体重的关系。 方法 于2012年8月～2013年12月在启东市妇幼保健所婚前医学门诊及产科门诊，对前来进行婚前医学咨询或孕期保健的妇女，按照知情同意原则，招募和纳入研究对象。测量孕12周前(纳入时)体重、身高；在孕12 W、孕28 W、孕36 W、分娩前及产后2 d内测量体重；生产时测量新生儿体重、身长等体格指标。应用Pearson相关系数分析孕妇孕期增重与新生儿体重的相关性。结果 共收集416例孕妇完整资料并纳入统计学分析。这些孕期妇女的孕前平均体质指数(BMI)为(21.17±2.75)kg/m2。孕妇孕前BMI与孕12、28、36 W及分娩前各期增重与新生儿出生体重的相关性有统计学意义，均呈正相关。早孕期孕妇体重增长速度最慢，为(0.035±0.002)kg/周；晚孕期间体重增长速度最快，为(0.550±0.067)kg/周。各孕期孕妇体重增长速度比较差异有高度统计学意义(P<0.01)。 结论 孕妇孕期增重越大，所生新生儿体重也越大；随孕周的增加，孕妇体重增长速度增加；随新生儿出生体重增大，剖宫产率也增高。应根据孕妇孕期增重情况，在妊娠中、晚期给予有针对性的饮食指导，以减少巨大儿、妊娠并发症的发生。

[Abstract] Objectives To analyze the relationship between the weight growth in the pregnancy and the birth weight of newborn baby. Methods The pregnant women who visited the doctors for obstetrical outpatient service in Qidong maternal and children health center in the period from August 2012 to December 2013 were included in the research with informed consents.The indicators which were measured were as belows： the weight and height of the pregnant women in pregnant 12 weeks，the weight of them in 12 weeks，28 weeks，36 weeks and 2 days after delivery，the weight of placenta，the volume of amniotic fluid and the postpartum hemorrhage，and the weight and the height of the newborns. Pearson correlation analysis was used. Results There were 416 pregnant women included in the analysis. The mean of BMI of the women before pregnancy was(21.17±2.75) kg/m2. The relations between the birth weight of newborns and several weights of pregnant women were all positive and showed statistical significance which were before pregnancy and during pregnant 12，28，36 week and before delivery. The mean weight growth rate in early pregnancy was(0.035±0.002)kg per week，and that in late pregnancy was(0.550±0.067)kg per week. The difference of weight growth rates in several periods were statistical significant(P<0.01). Conclusion The more the pregnancy women will gaine the weight， the more the birth weights of the newborns are. The weight growth rates will increasealong with the pregnancy. The caesarean delivery rate will increase along with the growth of the birth weight of newborns. Dietary guidance should be conducted during the middle and later pregnancy according to the weight growth condition of the women for the prevention of the incidence of giant baby and pregnant complications.
