摘要
目的探讨采用问卷进行高校教师亚健康状态筛检的标准。方法采用问卷调查结合健康体检了解157名高校教师亚健康的发生情况，借助受试者工作特征（receiver operating characteristic curve，ROC）曲线拟定亚健康问卷筛检的标准。结果亚健康发生率为32．5％（51／157），亚健康者的问卷得分明显高于健康者（z=-9．920，P〈0．001）。ROC曲线分析显示：问卷得分为18．5时曲线下的面积达0．98，筛检的灵敏度为96．1％，特异度为95．2％，正确指数为0．913；符合率为0．955，Kappa值为0．899（P〈0．001）；阳性预测值为90．7％，阴性预测值为98．0％。结论基于该问卷对高校教师亚健康进行筛检的判断标准可能为18．5分。
Objective To explore the cut-point of questionnaire score for Sub-health status among college teachers. Methods 157 teachers were investigated using questionnaires and health check, receiver operating characteristic curve （ROC） was used to select the cut point for sub-health status. Results The prevalence of sub-health among college teachers was 32.5 percent （ 51/157 ） with the significant difference between healthy and sub-healthy people （z = - 9. 920,P 〈 0.001 ）. The results of ROC analysis indicated that the cut point was 18.5 with an area proportion of 0.98, sensitivity of 0. 961, specificity of 0. 952, Youden index equal to 0. 913, crude agreement of 0.955, Kappa value of 0.899 （P 〈 0.001 ）, positive predictive value of 0. 907, and negative predictive value of 0. 980. Conclusion The score of 18.5 may be a good cut point to screen sub-health status among college teachers using this questionnaire.
