【摘要】 目的了解我国中老年人自报高血压的准确性,分析其影响因素。方法利用中国健康与养老追踪调查2011~2012年全国基线调查数据,以实际测量的诊断血压水平作为金标准,计算自报高血压的灵敏度、特异度等。并用非条件logistic回归分别分析影响准确度的因素。结果自报高血压的灵敏度低(56.3%),但特异度很高(96.9%),Kappa系数为0.57。影响自报准确性的因素有年龄、性别、教育程度、经济状况、医疗服务利用频率、糖尿病史和医疗保险。结论自报数据低估人群的高血压患病率,但不同亚组人群的自报数据的准确性有差异。更多还原

【Abstract】 Objective To determine the validity of self-reported hypertension and its associated factors in Chinese elderly populations.Methods Self-reported data of 13 610 elderly participants of the China Health and Retirement Longitudinal Study were compared with their actual blood pressure measurements.The sensitivity and specificity of self-reported hypertension were calculated corrected for current medication use.Multivariate logistic regression analysis was performed to identify individual characteristics that independently predicted the accuracy of self-reports.Results Overall,self-reported hypertension had low sensitivity(56.3%)and high specificity(96.9%).Agreement between self-reported data and medical records was moderate(Kappa=0.57).The multivariate analysis identified age,sex,education,financial situation,health service utilization,history of diabetes and types of medical insurance as significant factors that determined the validity of self-reported data.ConclusionSelf-reporting leads to underestimation of the prevalence of hypertension.The accuracy of self-reporting differs among subpopulations.更多还原
