【目的】了解海淀街道新生儿出生体重情况及影响因素,对妇幼保健工作提供科学依据。【方法】对海淀街道2004~2008年活产1 337例新生儿体重及相关因素进行统计分析。【结果】①1 337例新生儿中,平均出生体重为(3 376.50±464.27)g,男婴为(3 426.7±459.71)g,女婴为(3 320.1±463.26)g,均超过了WHO的国际参考值(男婴3 300g,女婴3 200g),正常体重儿男婴出生体重明显高于女婴。②早产儿发生率4.41%,低体重出生儿发生率2.39%,早产儿低体重发生率37.29%;巨大儿发生率7.18%。③孕母平均分娩年龄为(29.79±3.47)岁,不同年龄组新生儿出生体重差异无显著性;孕母平均受教育年限为(15.95±2.59)年,不同学历组新生儿出生体重差异无显著性。④37~42周出生的新生儿出生体重随孕周增长而增长。⑤多元回归显示孕妇的年龄、学历和性别对新生儿出生体重的影响无显著性。分娩方式和母孕期危险因素对新生儿出生体重的影响有显著性。【结论】重视新生儿体重变化的研究,加强孕产妇系统管理,降低低出生体重发生率和巨大儿发生率,降低剖宫产率。
【Objective】 To understand the birth weight and influencing factors of newborns in Haidian Street and provide scientific basis for maternal and child health care work. 【Method】 The body weight and related factors of 1 337 newborns live in Haidian Street from 2004 to 2008 were statistically analyzed. 【Results】 ①The average birth weight was (337.6 ± 464.27) g in 1 337 newborns, (3 426.7 ± 459.71) g in male infants, and (3 320.1 ± 463.26) g in female infants, all exceeding WHO international Reference value (3 300 g for baby boy and 3 200 g for girl infant), the birth weight of the normal weight infant boy is significantly higher than that of the baby girl. The incidence of premature children was 4.41%, the incidence of low birth weight was 2.39%, the incidence of low birth weight was 37.29%, and the incidence of macrosomia was 7.18%. ③ The mean age at delivery was (29.79 ± 3.47) years old. There was no significant difference in birth weight between different age groups. The average age of education for pregnant women was (15.95 ± 2.59) years. There was no significant difference in birth weight among newborns Sex. ④ The birth weight of newborns born in 37-42 weeks increased with gestational age. ⑤ multiple regression showed that pregnant women of age, education and gender had no significant effect on newborn birth weight. The mode of delivery and the risk factors of motherhood during pregnancy have significant effects on birth weight. 【Conclusion】 Emphasis on weight changes in newborns, strengthening maternal system management, reduce the incidence of low birth weight and macrosomia, reduce the rate of cesarean section.
