摘　　要：目的分析高龄老人虚弱指数的个体和区域影响因素。方法利用中国老年健康影响因素跟踪调查(CLHLS)2011年横断面数据,对其中80岁及以上的高龄老人计算虚弱指数,通过统计描述和分层线性模型,分析其个体和区域影响因素。结果高龄、女性、非独居、城镇居住、经济自评差、社会参与度低、健康食品摄入不足的高龄老人虚弱指数高。低气温、高工业废气与个体因素有交互作用,总体上工业废气排放越高,平均气温越低,则虚弱指数越高,并且这两项因素在最终模型中可以解释虚弱指数区域差别的54.8%(残差方差比例),模型可靠性为0.832。结论高龄老人虚弱指数可能受到个体和区域等多因素影响。Objectives To analyze the individual and environmental factors of frailty index of the old people aged 80 years and over.Methods Calculating frailty index of the old people aged 80 years and over and participated Chi-nese Longitudinal Healthy Longevity Survey 201 1.Statistical description and Hierarchical Linear Model were used to analyze the individual and regional factors.Results Frailty index will be higher for those who are in advanced age, female,not living alone,urban residents,low economic self-assessment,low social participation level,low health food intake,low temperature and high industrial waste gas emission.The two environmental factors explained 54.8% of regional residual variance and the reliability of the model is 0.832.Conclusions Frailty index of Chinese oldest old shows significant relationship with individual factors and the environmental factors.
