目的:了解婴儿出生体重情况,出生体重对剖宫产率的影响,为实施干预措施提供科学依据。方法:统计分析2005-2010年6月30日常山县活产儿出生体重、分娩方式。结果:婴儿平均出生体重为(3 294.64±441.31)g,男婴平均出生体重为(3 349.96±440.04)g,女婴平均出生体重为(3 231.57±439.99)g,男婴平均出生体重大于女婴平均出生体重(P<0.01);低体重儿发生率3.07%,巨大儿发生率6.35%;各年度婴儿平均出生体重、低体重儿、巨大儿发生率比较差异均无统计学意义(P<0.01);剖宫产率呈逐年增长趋势,剖宫产组与阴道分娩组婴儿出生体重比较差异无统计学意义(P<0.01)。结论:常山县婴儿出生体重在总体上是良好的,造成剖宫产率升高的主要原因不是出生体重。但是要继续提高围产期保健质量,重视孕期营养指导,监测孕妇体重增长,控制胎儿体重在适宜范围,及时治疗合并症和并发症,减少低体重和巨大儿的发生,正确掌握剖宫产手术指征,努力降低以社会因素为指征的剖宫产率。
OBJECTIVE: To understand the impact of infant birth weight and birth weight on the rate of cesarean section and to provide a scientific basis for the implementation of intervention measures. Methods: Statistical analysis was made on the birth weight and delivery method of live births in Changshan County from June 2005 to June 30, 2010. Results: The average birth weight of infants was (3 294.64 ± 441.31) g, the average birth weight of infants was (3 349.96 ± 440.04) g, and the average birth weight of infants was (3 231.57 ± 439.99) g. (P <0.01). The incidence of low birth weight was 3.07% and the incidence of macrosomia was 6.35%. There was no significant difference in the average birth weight, low birth weight and macrosomia between infants in each year (P < 0.01). The rate of cesarean section increased year by year. There was no significant difference in birth weight between cesarean section group and vaginal delivery group (P <0.01). CONCLUSIONS: The birth weight of babies born in Changshan County is generally good. The main reason for the increased cesarean section rate is not birth weight. However, we should continue to improve the quality of perinatal care, emphasis on nutritional guidance during pregnancy, monitoring of pregnant women weight gain, control of fetal weight in the appropriate range, timely treatment of complications and complications, reduce the incidence of low body weight and huge children, correct grasp of cesarean section Indications, efforts to reduce the social factors as indications of cesarean section rate.
