小学教师疲劳与慢性疲劳综合征的现状及其相关性研究

摘要

Objective To understand the status of fatigue and Chronic fatigue syndrome (CFS) in primary school teachers, and to analyze the correlation between fatigue and CFS so as to provide a basis for prevention and control of CFS. Methods The cluster stratified sampling was used to randomly select 934 teachers from 10 primary schools in Nanchang cit-y. Among them questionnaire survey was conducted and Fatigue Self - assessment Scale (FSAS) was taken for examination. Results (1) The prevalence rate of CFS among the primary school teachers was 12. 88% [95% CI (0. 107, 0. 151)], 89. 47% of the teachers had a feeling of fatigue in different degrees. The average FSAS score of the primary school teachers was ( 28. 52 ± 15. 34 ) (total score was 88). ( 2) The prevalence rate of CFS went higher with the increased fatigue degree ( χ2tendency = 80.237, P < 0. 001) . ( 3) The average FSAS score in the CFS group was ( 44. 78 ± 15. 74 ) , which was significantly higher than ( 26. 12 ± 15. 74 ) in the control group (t = 13. 322, P < 0. 05 ). (4 ) The FSAS score of optimal cut - off point for diagnosis of fatigue, determined by the receiver operating characteristic curve, was 34. 5. The sensitivity and specificity at this cut - off point were 76.52% and 75. 45%, respectively. The area under curve was 0. 817 (95%CI (0.778, 0.855)). (5) The development of CFS was correlated with fatigue (Cox&Snell coefficient: R2 =0. 144; Nagelkerke coefficient; R2 =0. 268) . Conclusion The fatigue phenomenon is common among primary school teachers and their prevalence rate of CFS is relatively high. Continual or repeated fatigue is one of the important influencing factors to CFS.%目的 了解小学教师疲劳与慢性疲劳综合征(chronic fatigue syndrome,CFS)的现状,对教师疲劳与CFS的相关性进行分析,为CFS的防治提供依据.方法 采用分层整群抽样研究方法,随机抽取南昌市10所小学,对这10所小学中所有从事教学工作的934名教师进行问卷调查和疲劳自评量表(fatigue self-assessment scale,FSAS)检测,共获取有效问卷893份.结果 (1)小学教师CFS的患病率为12.88％ (115/893) [95％CI (0.107,0.151)],89.47％的教师有不同程度的疲劳感,FSAS评定平均得分为(28.52±15.34)分(满分为88分)；(2) CFS患病率随疲劳程度的增加而升高(x2趋势=80.237,P＜0.001)；(3) CFS患者的FSAS评定平均得分为(44.78±15.74)分,高于非CFS者的(26.12±15.74)分,差异有统计学意义(t=13.322,P＜0.05)；(4)通过受试者工作特征(ROC)曲线获得的用于诊断CFS的FSAS评定得分最佳截断值为34.5分,灵敏度为76.52％,特异度为75.45％,曲线下面积为0.817 [95％CI (0.778,0.855)]; (5)疲劳与CFS的发生相关,Cox&Snell决定系数R2 =0.144,Nagelkerke决定系数R2 =0.268.结论 小学教师疲劳现象较普遍,CFS患病率较高；教师长期持续或反复的疲劳,是导致CFS发病的重要影响因素之一.
