Abstract: Objective According to the Urumqi municipal hospital delivery records in recent ten years,analysis of the neonatal birth weight,study of low birth weight infants and macrosomia the incidence and the related factors. Method From 2002 January to 2011 December in Urumqi city hospital,5 421 cases of neonatal birth weight were investigated retrospectively,and analyzed of gestational age,maternal age,maternal race and other factors associated with low birth weight,fetal macrosomia relationship. Results 1)5 421 cases of neonatal mean birth weight was (3 399.95± 475.94)g,baby boy mean birth weight was (3 457.05± 475.94)g,girl's mean birth weight was (3 335.43±467.72)g.2)The rate of low birth weight was 2.60%,associated with preterm birth,maternal,newborn gender related tribe,the differences were statistically significant.3)The incidence of macrosomia was 10.20%,with gestational age,maternal age,neonatal sex related,the differences were statistically significant. Conclusion Nearly ten years neonatal birth weight increases smoothly; the prevention of preterm birth is important measures to reduce the rate of low birth weight,the higher incidence of macrosomia,should be paid attantion to,neonatal birth weight is necessary to observ year after year.

摘要： 目的 根据乌鲁木齐市某三甲医院近十年的住院分娩记录,分析新生儿出生体重十年变化趋势,了解低出生体重儿、巨大儿发生情况及相关因素。 方法 对2002年1月-2011年12月在乌鲁木齐市某三甲医院住院分娩的5 421例新生儿的出生体重进行回顾性调查,分析孕周、孕母年龄、孕母族别等因素与低出生体重、巨大儿的关系。 结果 1)5 421例新生儿平均出生体重为(3 399.95±475.94)g,男婴平均出生体重为(3 457.05±475.94)g,女婴平均出生体重为(3 335.43±467.72)g。2)低出生体重儿发生率为2.60%,与早产、孕母族别、新生儿性别有关,差异有统计学意义。3)巨大儿发生率为10.20%,与孕周、孕母年龄、新生儿性别有关,差异有统计学意义。 结论 近十年新生儿的出生体重平稳增加; 预防早产是降低低出生体重儿发生率的重要措施,巨大儿的发生率较高,应引起重视;新生儿的出生体重有必要逐年观察。
