摘　　要：为查找脐带绕颈的危险因素 ,收集 1995年至 1996年在广西医科大学第一附属医院产科分娩者的分娩史、出生史、脐带绕颈情况及一般人口学社会学特征等资料 ,共 15个因素 ,先采用单因素非条件 L ogistic模型分析 ,然后选有显著性影响的因素作多因素非条件 L ogistic模型分析。单因素分析表明 ,新生儿体重、新生儿身长、脐带长度和羊水量对脐带绕颈均有显著影响 (P <0 .0 5 )。多因素分析表明 ,脐带长度和羊水量与脐带绕颈发生率呈正相关 ;新生儿体重和新生儿身长与脐带绕颈发生率呈负相关 ;脐带长度的标准回归系数和 OR值最大 ,分别为 2 .915 8和 3.85。表明脐带过长是脐带绕颈的主要危险因素。In order to search the risk factors of cord around neck,we collect the data of parturients in the department of Obstetries and Gynecology of from 1995 to 1996,such as delivery history,birth history,the condition of cord around neck and the charactoristics of demography and sociology,15 factors in total. One way unconditional Logistic Model was used first and then the multivariable unconditional Logestic Model among these significant factors.The weight,body length,cord length of the newborn and the volume of amniotic fluid have the significant effects on the cord around neck with one way analysis (P<0 05).The cord length,volume of amniotic fluid have the positive correlation with the incidence rate of cord around neck,where as the weight and body length of the newborn have negative correlation with it when we use multivariable unconditional Logestic Model.The value of standand regression coefficient and Odds Ratio(OR) of the cord length are higher than others,which is 2 9158,3 85 respectively.It shows that a long cord is the major risk factor of cord around neck.
