目的研究影响巨大儿发生的危险因素。方法回顾性队列研究法对3 869例产妇进行调查,进行logistic回归分析。结果对巨大儿产生影响的因素有8项,对总判断力(correct class%)为91.8%。依OR值大小,各因素影响程度从强到弱依次为:新生儿性别、分娩方式、孕周、宫高、孕次、孕妇身高、腹围和孕早期BMI。结论①男婴发生巨大儿的可能性大于女婴,孕妇的孕周越大、宫高越高、孕次越多、身高越高、腹围越大、孕早期BMI越大,发生巨大儿的可能性越大。②巨大儿剖腹产的可能性大。
Objective To study the risk factors that affect the occurrence of macrosomia. Methods A retrospective cohort study was conducted on 3,869 mothers and analyzed by logistic regression. The results of the huge children have eight factors, the total judgment (correct class%) was 91.8%. According to the OR value, the influence degree of each factor from strong to weak is as follows: neonatal sex, mode of delivery, gestational age, uterine height, pregnancy time, pregnant women ’s height, abdominal circumference and early pregnancy BMI. Conclusions ①The probability of occurrence of huge children in infants is higher than that of female infants. The gestational age of pregnant women is bigger, the higher the height of the uterus is, the more the pregnancy is, the higher the height, the larger the abdominal circumference, the larger the BMI in the first trimester, The greater the likelihood. ② huge children caesarean section possibility.
