非糖尿病性巨大儿的相关临床分析

目的:探讨非糖尿病性巨大儿发生的相关因素及临床特点。方法:选择足月出生的巨大儿149例,同时随机选择同期出生的足月正常体质量儿166例作为对照,分析新生儿母亲的年龄、孕次、产次、孕周、孕期增长体质量及孕末期体质指数(BMI)等。结果:非糖尿病性巨大儿的发生以男婴居多,其平均身长、体质量、股骨长、双顶径显著高于对照组(P<0.05);非糖尿病性巨大儿母亲的平均身高、孕期增长体质量、孕末期BMI及围产期发病率、剖宫产率显著高于对照组(P<0.05)。结论:非糖尿病性巨大儿是有别于糖尿病性巨大儿的一种正常儿,其发生除了与遗传因素有关外,与其母亲的营养过量摄入密切相关。

A clinical analysis of the non-diabetic factors and fetal macrosomia

Objective: To analyze the clinical characteristics of non-diabetic fetal macrosomia and their mothers.Methods: A retrospective case control study design was used to analyze 149 cases of non-diabetic fetal macrosomia and their mothers with the normal oral glucose tolerance test(OGTT) by comparison with 166 randomly included newborns of normal birth weight.Results: More cases of non-diabetic fetal macrosomia were found in the male neonates.The body weight,height,FL and BPD averaged significantly higher in the macrosomia group than in the control,and so did the body weight,height,uterus height,abdominal circumference and gestational age of the mothers.The rates of cesarean section and other obstetric complications were also higher in the macrosomia group.Conclusion: Different from the diabetic macrosomic fetus,the non-diabetic macrosomic fetus is a normal one,the incidence of which is associated with mothers'excessiver pregnancy nutrition as well as with genetic factors.
