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 research the health equity of infant death in China from 1981 to 2010. Methods Using data from 《China Health Statistics Year book》 about infant death situation and range method, the population attributable risk percentage, concentration index, concentration curve, analysis the correlation between the infant mortality rate and the each province per capita GDP, quantitative analysis of infant death health equity were analyzed between the provinces in our country. Results The correlation coefficient between province's per capita GDP and infant mortality were relevance had increased.All concentration indexes were negative and concentration curve were above standard, which indicated infant mortality in poor provinces was negative from 1981 to 2010, and higher than in rich provinces. Conclusions The relationship between infant mortality and social economic level take on significant negative correlation and the correlation show a trend of increase.Although the health inequity in infant mortality has been improved, but not obvious.
