| 目的 分析2004－2018年中国<1岁组儿童低出生体重儿死亡水平与变化趋势。方法 利用公开出版的《2004－2018年中国死因监测数据集》，分析我国<1岁组儿童在不同性别、城乡、地区的低出生体重儿死亡率、构成比及变化趋势。分析城乡、东/中/西部地区不同性别<1岁组低出生体重儿死亡率、构成比及变化趋势。采用加权最小二乘法拟合Joinpoint回归模型分析时间变化趋势，计算各时间段内年度变化百分比（APC）、全时段内平均年度变化百分比（AAPC）及其95% CI。结果 2004－2018年<1岁组低出生体重儿死亡率呈下降趋势，年平均下降幅度为-8.0%（95% CI：-10.6%~-5.4%），不同性别、城乡、地区间的差异逐渐缩小。2004－2018年<1岁组低出生体重儿死亡构成比呈上升趋势，年平均上升幅度为1.6%（95% CI：0.1%~3.2%）。<1岁组低出生体重儿死亡率城市（38.74/10万）高于农村（30.44/10万），城市<1岁组低出生体重儿死亡率年平均下降速度（-3.4%，95% CI：-7.0%~0.3%）低于农村（-9.3%，95% CI：-12.0%~-6.6%）；<1岁组男童低出生体重儿死亡率（36.25/10万）高于女童（28.22/10万）；西部地区<1岁组儿童低出生体重死亡构成比呈上升趋势，平均每年变化为3.2%（95% CI：1.7%~4.8%），变化速度高于东部地区的-0.5%（95% CI：-2.3%~1.4%）；不同城乡、地区间<1岁组低出生体重儿死亡率男童均高于女童。结论 2004－2018年<1岁组低出生体重儿死亡率呈下降趋势，构成比均呈上升趋势，建议以男童和中、西部地区儿童作为今后妇幼保健工作的重点人群。 |

| Objective To analyze the level and trend of low birth weight mortality in children under 1 year old in China from 2004 to 2018. Methods The published Data Set of National Mortality Surveillance from 2004 to 2018 was used to analyze the low birth weight mortality rate, constituent ratio and changing trend in boys and girls, in urban area and rural area and in different regions in China. The Joinpoint regression model fitted by the weighted least square method was used to analyze the time variation trend and calculate the annual percentage change (APC), the average annual percentage change (AAPC) and their 95% confidence intervals in each time period. Results From 2004 to 2018, the low birth weight mortality rate in children under 1 year old in China showed a decreasing trend with an AAPC of -8.0% (95% CI: -10.6% - -5.4%). The differences between boys and girls, between urban area and rural area and among different regions gradually reduced. From 2004 to 2018, the constituent ratio of low birth weight mortality showed an increasing trend with an AAPC of 1.6% (95% CI: 0.1%-3.2%). The mortality rate in urban area (38.74 per 100 000) was higher than that in rural area (30.44 per 100 000). The annual average declining speed of low birth weight mortality rate in urban area (AAPC= -3.4%, 95% CI: -7.0%-0.3%) was slower than that in rural area (AAPC= -9.3%, 95% CI: -12.0% - -6.6%). The low birth weight mortality rate of boys (36.25 per 100 000) was higher than that of girls (28.22 per 100 000). The low birth weight mortality constituent ratio in western region showed an increasing trend, its average annual percentage change (AAPC=3.2%, 95% CI: 1.7%-4.8%) increased faster than that of the eastern region (AAPC=-0.5%, 95% CI: -2.3%-1.4%). In urban and rural areas and different regions, the rate of low birth weight mortality in boys was higher than that in girls. Conclusions From 2004 to 2018, the mortality rate of low birth weight in children under 1 year old showed a downward trend, and the constituent ratio showed an upward trend. Boys and children living in central and western regions should be the key population for maternal and child health care. |
