摘要
目的了解深圳市光明新区5岁以下儿童死亡率的情况和变化趋势,分析主要死亡原因,为制定干预措施提供依据。方法收集2008—2017年光明新区5岁以下儿童死亡监测资料,采用描述性统计方法和卡方检验分析5岁以下儿童主要死因和死亡率。结果 2008—2017年光明新区5岁以下儿童平均死亡率为3. 02‰,总体呈下降趋势(χ~2=5. 968,P <0. 05);婴儿死亡占5岁以下儿童死亡的63. 60%;流动人口5岁以下儿童死亡率明显高于常住人口(χ~2=86. 441,P <0. 001); 5岁以下儿童死因顺位前3位分别为意外伤害,先天异常、早产或低出生体重。结论光明新区5岁以下儿童死亡率呈下降趋势,但流动儿童死亡占比较重,意外伤害、先天异常、早产或低出生体重是5岁以下儿童死亡的重要原因,应进一步强化三级预防措施,以提高5岁以下儿童生命健康水平。
Objective To explore the mortality rate and analyze the leading causes of death based on death surveillance data of children under-five years old in Guangming district of Shenzhen,so as to provide scientific evidences for mortality controlling programs.Methods The death surveillance data of children under-five years old in Guangming district from 2008 to 2017 was collected. The under-five mortality rate and the leading causes of death were analyzed by descriptive statistic methods and Chi-square test. Results The average under-five mortality rate was 3. 02‰ from 2008 to 2017 in Guangming district,simultaneously with a significantly decreased trend( χ~2= 5. 968,P < 0. 05). Infant death accounted for 63. 60% of death among children under-five years old. The underfive mortality rate in migrants was significantly higher than the resident population( χ~2= 86. 441,P < 0. 05). Accidental injury was the top death cause in children under-five years old; Congenital malformation and preterm delivery/low birth weight were the top three death cause in neonate,infant and children under-five years old respectively. Conclusion The under-five mortality rate had a decline trend in Guangming district,especially in migrants with a high level.
