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 find out the risk factors around the neck of the umbilical cord, we collected 15 cases of labor history, birth history, umbilical cord around the neck and socio-demographic characteristics of general population from 1995 to 1996 in the first affiliated hospital of Guangxi Medical University Factors, first using univariate non-conditional L ogistic model analysis, and then select the factors that have a significant impact as a multi-factor non-conditional L ogistic model analysis. Univariate analysis showed that neonatal weight, neonatal length, cord length and amniotic fluid volume had significant effects on the cord around the neck (P <0.05). Multivariate analysis showed that cord length and amniotic fluid volume and the incidence of cord around the neck was positively correlated; neonatal weight and neonatal length and the incidence of cord around the neck was negatively correlated; standard regression coefficient and OR values of cord length were the largest, respectively, 2 .915 8 and 3.85. That the umbilical cord is too long is the main risk factor around the neck.
