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、晚期摄入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入热量控制在每天平均摄入2100千卡左右可减少围生期不良结局。
Objective To investigate the effect of heat intake during pregnancy on maternal and infant women with overweight and obesity. Methods 189 cases of pregnant women were divided into three groups: group A, 67 cases of overweight and obese pregnant women, the implementation of diet control; B group of 63 cases, overweight and obese pregnant women, not diet control; C group of 59 cases of normal weight pregnant women. Calculate the actual monthly intake of calories after 12 weeks of pregnancy, recording biparietal diameter, abdominal circumference, femur length and complications during pregnancy. Results The heat intake in the second trimester and third trimester in group A was significantly lower than that in group B and C (P <0.01). The pregnancy complications and complications in group A were significantly lower than those in group B (P <0.05). The three groups of middle and late pregnancy calories and newborn birth weight, biparietal diameter, abdominal circumference, femur length were positively correlated (P <0.05). Conclusion Overweight and obese pregnant women in the second trimester intake of calorie control intake of about 2100 kcal per day can reduce the perinatal adverse outcomes.
