农村地区艾滋病家庭生活状况与影响因素的结构方程模型分析

Structural Equation Model in the Research of the AIDS Family Burden and its Influencing Factors in Country Areas

目的了解艾滋病患者家庭生活状况及其影响因素,探讨结构方程模型在艾滋病研究中的应用。方法采用多阶段随机整群抽样方法,在河南省艾滋病高发地区随机抽取1146例HIV/AIDS患者进行问卷调查,对调查数据进行结构方程模型拟合。结果从艾滋病家庭生活影响因素中提取2个公因子,从艾滋病家庭生活状况中提取3个公因子;结构方程模型拟合指数:χ2=999.95;自由度v=85;近似误差均方根RMSEA=0.097;正规拟合指数NFI=0.71。对人际关系有影响的因素主要是疾病有关因素;与日常生活有关的因素有个体因素;日常生活状况影响家庭境况。结论结构方程模型可以用于艾滋病相关因素研究。

Objective To analyze the family burden of acquired immune deficiency syndrome（AIDS） and its influencing factors, to explore the application of confirmatory factor analysis in medical studies. Methods Multi-stage random cluster sampling techniques was used to collect 1 146 participants in the higher prevalent regions of AIDS in Henan province. Structural equation model（SEM） was fitted to explore the relationship among AIDS family burden and its influencing factors. Results Two influencing factors and three factors of the AIDS family burden were extracted by factor analysis. The results of SEM showed the fitted indexes of model were good,χ^2 = 999. 95, v = 85, RMSEA = 0. 097, NFI = 0. 71. The main factor affecting the personal relationship was the disease factor, the main factor affecting daily life was demographics, and daily life had influence on the family status. Conclusion SEM is applicable in A/DS related factors.
