我国城镇居民与收入相关的健康不平等程度及影响因素分析

Income-Related Health Inequality of Urban Residents in China and Influencing Factors

目的探讨我国城镇居民与收入相关的健康不平等程度及其影响因素。方法应用中国健康营养调查(CHNS)2006年数据测算城镇居民健康集中指数,并分析各因素对健康不平等的影响程度。结果与收入相关的健康不平等集中指数绝大部分为负值,且在P=0.05水平上具有统计学意义,其中以辽宁、山东最为突出。地区收入中位数对数值以及基尼系数与收入相关健康不平等有关(P<0.01),居民所处收入阶层和年收入对数值两个指标的回归系数在P=0.01水平上不具统计学意义(P>0.05)。结论辽宁、山东省的健康不平等程度最高,湖北省最低。地区经济发展状况和收入分配公平情况是影响该地区与收入相关健康不平等程度的重要因素。

Objective To estimated the urban residents＇ income related health inequalities in China and the influencing factors. Methods The 2006 data from the China Health and Nutrition Survey （CHNS） were taken to calculate the health concentration index of urban residents, and the influencing extent of each factor was analyzed. Results The majority of the health concentration indexes of urban residents were minus, and with a statistic significance at the level of P = 0. 05, with those in Liaoning and Shandong provinces being evident. The logarithm value of regional income median and the Gini coefficient were correlated with the income - related health inequalities （ P 〈 0. 01 ）. The regression coefficients of residents＇ income level and logarithm value of annual income were of no statistic significance at the level ofP = 0. 01 （ P 〉 0.05 ）. Conclusion Provinces of Liaoning and Shandong are highest in health inequality, while province of Hubei is lowest. The condition of regionally economic development and income equality are the important factors for the income related health inequality.
