巨大儿68例发生因素分析

目的 对巨大儿发生进行多因素分析,找出影响巨大儿发生的危险因素,并探讨对孕期指导的临床意义.方法 回顾性分析2012年3月-2013年2月来我院住院分娩的560例孕妇的临床资料,通过单因素分析及多因素Lo-gistic分析研究巨大儿发生的危险因素,并了解孕期指导的意义.结果 单因素分析结果显示,孕妇的孕前体重指数（BMI）、产前空腹血糖、羊水过多、孕期延长及未接受孕期指导对巨大儿发生有影响（P＜0.05）;多因素Logistic回归分析结果显示,孕前体重过重（β=0.861,OR=2.507）、空腹血糖过高（β=1.861,OR-6.057）、羊水过多（β=2.984,OR=22.878）是巨大儿发生的危险因素,而孕期指导（β=-0.721,OR=0.564）是巨大儿发生的保护因素（P＜0.05）.结论 产前体重的过度增加、羊水过多、空腹血糖过高及孕期延长均可增加巨大儿的发生几率,而孕期指导是巨大儿发生的保护因素,值得临床推广应用.

The factor analysis of 68 cases of great children

Objective To multivariate analyze the huge children occurring and identify a tremendous impact child risk factors.Methods 560 pregnant women were analyzed with Logistic univariate analysis and multivariate analysis.Results Univariate analysis showed that the risk factors of the huge children were body mass index （BMI）,prenatal,prenatal fasting glucose,polyhydramnios,pregnancy prolongation and non-receive guidance （P＜0.05）.Logistic regression analysis showed that pregnancy overweight（β=0.861,OR =2.507）,fasting hyperglycemia （β=1.861,OR =6.057） and polyhydramnios（β=2.984,OR=22.878） were the risk factors for the huge children.Pregnancy guide （β=-0.721,OR=0.564） was the protective factor for the huge children （P＜0.05）.Conclusion The risk factors of huge child are excessive increase in weight,polyhydramnios,fasting hyperglycemia and prolonged pregnancy.
