孕期摄入热量对超重肥胖孕妇母婴的影响

摘要

目的 探讨孕期摄入热量对超重肥胖孕妇母婴的影响.方法 189例孕妇分为三组:A组67例,超重肥胖孕妇,实施饮食控制；B组63例,超重肥胖孕妇,未实施饮食控制；C组59例,正常体重孕妇.计算孕12周后每月实际摄入热量,记录双顶径、腹围、股骨长值和妊娠期合并症.结果 A组孕中期、孕晚期摄入热量明显低于B组和C组(P＜0.01).A组的妊娠合并症和并发症明显低于B组(P＜0.05).三组孕中、晚期摄人热量与新生儿出生体重、双顶径、腹围、股骨长度均呈明显正相关(P＜0.05).结论 超重肥胖孕妇孕中晚期摄人热量控制在每天平均摄人2100千卡左右可减少围生期不良结局.%Objective To study the effects of calorie intake on obese gravida and infant. Methods A total of 189 overweight and obese gravida was divided into three groups of A (67 overweight and obese cases, with diet control) ,B(63 overweight and obese cases, without diet control) and C(59 cases, without overweight and obesity). The real calorie taken monthly after 12 week of pregnancy was calculated and the biparietal diameter(BPD) ,circumference( AC) ,femoral length(FL) and complications of pregnancy were recorded. Results The calorie intake during middle and late pregnancy was lower in group A than that in groups of B and C(P<0. 01). The incidences of post-partum hemorrhage,Cesarean section, asphyxia of newborn, gestational diabetes mellitus, decidual of preeclampsia,anaemia in pregnancy and macrosomia in group A were obviously lower than these in group B(P<0. 05). The carole intake during middle and late pregnancy was positively correlated with the weight, BPD, AC, and FL of new borns(P<0. 05). Conclusion Keeping carole intake at about 2 100 kcal perday during middle and late pregnancy is helpful in reducing adverse outcomes.
