摘　　要：目的探讨家庭收入不平等性与人群健康状况的关系。方法本研究利用第四次国家卫生服务调查数据,基于基尼系数的计算原理计算家庭收入不平等指数(HII)。以调查人口占该县区总人口比例的倒数作为权重,拟合标化患病率与HII的加权线性回归方程,并不断加入其他变量探讨其影响是否会被剥夺。结果加权线性回归模型表现出HII与标化患病率的相关关系有统计学意义,且统计学意义不会随着其他变量的剔除与加入而被剥夺。由于标化患病率的分布为偏态分布,拟合对数转换回归模型后其拟合效果有所增加。结论收入不平等性对人群健康状况存在负面影响,应逐步缩小家庭收入不平等,以改善人群健康。Objective To explore the association between household income inequality and the health condition of the population.Methods The data of the Fourth National Health Services Survey were used,and the household income inequality index（HII） was calculated on the calculation principle of Gini coefficient.Having the reciprocal of the proportion of the surveyed population among the total population in the county as weight,the weighted linear regression equation model of HII and standardized prevalence rate（SPR） was fitted,and other variables were continually included to investigate whether their impacts on SPR were deprived.Results The weighted linear regression model showed that the HII was statistically correlated with the SPR,and the statistical significance was not deprived when other variables were excluded or included.Due to the SPR showed skew distribution,the model fitting efficiency increased after log transformation of SPR.Conclusions Household income inequality has negative impacts on the health condition of the population.It should be gradually reduced so as to improve the health of the population.
