城市医疗救助对象疾病经济负担与风险的影响因素研究

Research on Influencing Factors of Economics Burden and Risk of Diseases of Medical Aid Target in Urban China

目的:探讨城市医疗救助对象的疾病经济负担的影响因素。方法:调查1200名城市医疗救助对象的社会人口学特征、健康状况和疾病经济负担等,构造多元线性回归模型对疾病经济风险的影响因素进行探讨。结果:医疗救助对象家庭人均月收入为332.12元,月人均医疗支出为110.47元,疾病相对经济风险度Y/S0.33。以Ln(Y/S)为应变量进行多元线性回归分析,是否住院和人均月收入是有统计学意义的自变量,其偏回归系数分别为1.045和-0.001,P<0.01。结论:城市医疗救助对象的疾病经济负担和风险高,影响疾病经济风险最主要因素是是否住院,其次是人均月收入。

Objective： To analyze influencing factors of the economics burden and risk of diseases of medical aid target in urban Chiha. Method： the paper surveys the social-demographic characteristics, health status and the economics burden of disease of medieal aid target in urban China, and structures multiple linear regression model to explore the influencing factors of the economics burden and risk of diseases. Results： Per capita monthly income of medical aid target is Y332.12. The average monthly medical expenditure is 110.47 yuan. The relative economic risk of disease （Y/S） is 0.33. Ln （Y/S） should be the corresponding variable for multiple linear regression analysis. Being in hospital or not and the average monthly income are statistical significant variables. Conclusion： The economics burden and risk of diseases of medical aid target in urban China are high. Being in hospital or not is the strongest influencing factor to the economics risk, followed by the average monthly income.
