【摘要】：目的探讨孕前体质指数、孕期增重与子代出生体重的关系。方法选取在妇幼保健机构体检的婴儿母亲,采用问卷调查的方式收集母亲的一般情况、孕期增重及子代出生体重、身长等情况。采用方差分析、χ~2检验和多因素Logistic回归模型等方法进行数据统计分析。结果母亲孕前超重/肥胖的检出率为12.3%(199例),孕期增重过高的检出率为52.1%(842例)。超重/肥胖组其子代出生体重、巨大儿和大于胎龄儿的发生率均较高(P0.05),而子代的出生体重、巨大儿发生率、低体重儿发生率、小于胎龄儿发生率以及大于胎龄儿发生率均在孕期增重过高组,增重适宜组和增重不足组间存在差异(P0.05)。在控制了母亲年龄等因素后,孕前超重/肥胖增加了巨大儿(OR=1.7,95%CI:1.2~2.6)、大于胎龄儿(OR=1.7,95%CI:1.1~2.5)的发生风险,孕期增重过高则增加了巨大儿(OR=1.7,95%CI:1.2~2.5)、大于胎龄儿(OR=1.7,95%CI:1.1~2.4)的发生风险。而孕期增重不足能增加低体重儿(OR=2.2,95%CI:1.1~4.4)、小于胎龄儿(OR=2.0,95%CI:1.2~3.4)的发生风险。结论母亲孕前体质量指数及孕期增重均与巨大儿和大于胎龄儿的发生密切相关,且孕期增重不足与低体重儿和小于胎龄儿的发生也密切相关。孕期保健应该加强对孕妇体重的监测,防止其对新生儿出生结局产生不良影响。
[Abstract]:Objective to study the relationship between body mass index (BMI), weight gain during pregnancy and birth weight of offspring. Methods A questionnaire survey was used to collect the general situation of mothers, weight gain during pregnancy, birth weight and body length of their offspring in maternal and child health care institutions. ANOVA, 蠂 ~ 2 test and multivariate Logistic regression model were used to analyze the data. Results the detection rate of overweight / obesity in mothers before pregnancy was 12.3 and that in pregnant women was 52.1 and 842 respectively. The birth weight, macrosomia and gestational age in overweight / obesity group were higher than those in the control group (P 0.05), while the birth weight, macrosomia and low birth weight were higher in the overweight / obesity group. The incidence rate of small gestational age and greater than gestational age was higher than that of gestational age, and there was a difference between the appropriate weight gain group and the low weight gain group (P 0.05). After controlling for the age of the mother, overweight / obesity before pregnancy increased the risk of occurrence of OR1.795 CI1. 795 CI: 1.2 / 2.6, larger than the gestational age (OR 1.795 CI: 1.12.5), and increased the risk of greater weight gain during pregnancy (OR1.795 CI1. 2. 5, greater than the gestational age, OR1. 7 95: CI1. 12.4). However, insufficient weight gain during pregnancy can increase the risk of the occurrence of low birth weight infants with an or2. 2 + 95% CI: 1. 1 and 4. 4%, less than the gestational age of 2. 0 and 95% CI: 1. 2 / 3. 4). Conclusion the maternal weight index and weight gain during pregnancy are closely related to the occurrence of macrosomia and larger than gestational age, and the lack of weight gain during pregnancy is also closely related to the occurrence of low birth weight and small gestational age. Maternal health care should strengthen the monitoring of maternal weight to prevent its adverse impact on neonatal outcomes.
