四川省2001-2009年婴儿死亡率变化趋势及死因分析

摘要

目的 了解2001-2009年四川省婴儿年龄别和主要死因别死亡率的变化趋势.方法 采用四川省5岁以下儿童死亡监测收集的2001-2009年监测点儿童死亡资料,计算城乡新生儿、婴儿死亡率及婴儿死因别死亡率.结果 2009年四川省新生儿、婴儿死亡率分别为7.6‰和12.1‰,较2001年(18.6‰和25.5‰)分别下降了59.1%和35.0%;2009年城市新生儿、婴儿死亡率分别为3.7‰和6.5‰,较2001年(4.7‰和7.5‰)分别下降了22.3%和13.1%;2009年农村新生儿、婴儿死亡率分别为9.6‰和14.3‰,较2001年(25.2‰和34.0‰)分别下降了62.0%和57.9%;2001-2009年四川省婴儿的早产或低出生体重、出生窒息、肺炎、意外窒息、败血症死亡率有明显下降趋势.结论 2001-2009年四川省城市和农村新生儿、婴儿死亡率出现明显下降趋势,其中以肺炎、意外窒息等可避免死因下降尤为显著.%Objective To study the trend of infant mortality and the leading cause of the deaths in Sichuan province from 2001 to 2009.Methods Data presented in this report was obtained from the child mortality surveillance network with target population as children under 5 years of age.Rates on infant mortality,neonatal mortality and indirect estimation of infant mortality were calculated.Results The neonatal mortality rate and infant mortality rate in Sichuan dropped from 18.6,25.5 in 2001 to 7.6,12.1 per 1000 live birth in 2009,with rates of decline as 59.1% and 35.0%,from 2001 to 2009.In urban areas of Sichuan,the neonatal and infant mortality rates dropped from 4.7,7.5 in 2001 to 3.7 and 6.5 per 1000 live birth in 2009,with the rates of decline as 22.3% and 13.1%.In the rural areas of Sichuan,the neonatal and infant mortality rates dropped from 25.2 and 34.0 in 2001 to 9.6,14.3 per 1000 live birth in 2009,with rates of decline as 62.0%,57.9% from 2001to 2009.Conclusion In both urban and rural areas,the neonatal and infant mortality rates had decreased drastically from 2001 to 2009,due to the decrease of avoidable deaths as pneumonia and diarrhea in infants.
