新生儿低出生体重(以下简称低出生体重)是5岁以下儿童死亡的常见病因之一。为摸清我省城乡新生儿低出生体重发生率的现状,找出新生儿低出生体重发生的重点人群及主要影响因素并进行重点干预,我们在我省的昆明市、大理市、建水县和大关县对1998年9月～1999年3月出生的新生儿进行了低出生体重抽样调查。结果表明,我省农村低出生体重发生率高于城市和全国平均水平。降低我省新生儿低出生体重发生率的主要干预对象是农村孕产妇。孕周、怀孕中后期食欲、胎数、脐带异常及胎儿性别等因素是造成低出生体重的主要原因,对此探讨了有关的干预对策。
Neonatal low birth weight (hereafter referred to as low birth weight) is one of the common causes of death among children under 5 years of age. In order to find out the incidence of low birth weight in newborns in urban and rural areas of our province, find out the key population and main influencing factors of newborns with low birth weight and make key interventions. In Kunming, Dali and Jianshui And Daguan County carried out a low-birth-weight sampling survey of newborns born from September 1998 to March 1999. The results show that the incidence of low birth weight in rural areas in our province is higher than the urban and national average. The main intervention to reduce the incidence of neonatal low birth weight in our province is rural pregnant women. Gestational weeks, the middle and late pregnancy appetite, fetal number, umbilical cord abnormalities and fetal gender and other factors is the main reason for the low birth weight, to explore the relevant interventions.
