目的研究1981-2010年间我国婴儿死亡健康公平性的变化情况。方法利用《中国卫生统计年鉴》中婴儿死亡情况的有关资料,分析婴儿死亡率和省际人均GDP之间的相关性,利用极差法、人群归因危险度百分比、集中指数、集中曲线等指标定量分析我国各省份间婴儿死亡的健康公平性。结果从1981-2010年各省市的人均GDP和婴儿死亡率之间相关系数均为负值。省际集中指数均为负值,集中曲线均在标准线之上,反映出婴儿死亡情况主要集中于社会经济发展水平较落后的省份。结论从1981-2010年,我国婴儿死亡情况和社会经济水平之间呈显著的负相关性且相关性增强;省际间婴儿死亡的健康不公平略有所改善。
Objective To study the changes in the health equity of infant mortality in China from 1981 to 2010. Methods The data of infant mortality in China Health Statistics Yearbook were used to analyze the correlation between infant mortality rate and provincial average per capita GDP. Using the method of difference method, the percentage of people at risk, concentration index and concentration curve Quantitative Analysis of Health Equity among Infant Deaths in Various Provinces in China. Results From 1981 to 2010, the correlation coefficient between per capita GDP and infant mortality in all provinces and cities was negative. The inter-provincial concentration indices are all negative and the concentration curves are all above the standard line, reflecting the fact that infant deaths are mainly concentrated in provinces with less developed socio-economic development. Conclusions From 1981 to 2010, there was a significant negative correlation between the infant mortality and the socio-economic level in our country and their correlation was enhanced.
