The Study Of Effect Factors Of Chronic Fatigue Of Social People And Objective Index Of Graduates' Chronic Fatigue

Objective Get the message of the characteristic of demography distribution of CF among Taiyuan city people;Explore the social and psychological effect factors of chronic fatigue(CF); Explore the correlation of chronic fatigue and personality and reaction time(RT)and electroencephalography(EEG)of undergraduate students in Shanxi medical university and the diagnostic value of RT and EEG in predicting CF.Methods 1,1130 people were selected from medical examination center in Maternal and Child Health hospital of Shanxi and the hospital affiliating Shanxi medical university with purposive sampling and community of Guoshi in Taiyuan city with sampling method of simple random and middle school of Jinshan in Taiyuan city and college of Taiyuan Ligong and Shanxi medical university with random cluster sampling.They were investigated with questionnaire about CF and social and psychological factors.The questionnaire includes six aspects.(1)Social demographic character investigation,such as sex,age,occupation,education,marriage;(2) Diagnosing CF with standard defined by American center of disease control and prevention in research outline of Chronic Fatigue Syndrome,and fatigue was scaled refer to Fatigue Scale authorized by Chalder;(3)Social factors include 24 questions such as load of work or study and the environment,lifestyle,interpersonal relationship,institution of health examination,etc; (4)Psychological factors,using the general health questionnaire(GHQ-20)authorized by Goldberg and reviewed by Lihong in the research institute of Tsinghua university,include three dimension of self-affirmation and gloom and depression;(5)Social support,using the Social Support Rating Scale(SSRS)consisted of objective support and subject support and availability of support and authorized by Xiao Shuiyuan in Xiangya medical university,includes 10 questions;(6)Coping style,using the Simple Coping Style Scale organizationed by Xie Yaning and consisted of two dimension of positive coping and passive coping,includes 20 questions.2,200 students were selected with purposive sampling in grade of four and five of bachelor and master class in Shanxi medical university and investigated by above-mentioned questionnaire and surveyed with personality and RT and EEG.(1)The students' personality were tested with Kartaier's 16 personality factors test(16PF)reviewed by Beijing Normal University.(2)Their RT were tested with tester of multifunction in psychology and physiology of DDX-200 producted in Boda institute in Beijing;the tests were respectively visual simple RT and visual choice RT and knock RT.(3)Their EEG test was completed with mobile tester producted in Weisi company in Nanjing city in Jiangsu and performed with disk electrodes applied to the scalp with collodion in accordance with the 10/20 system.And computerized spectral analysis were conducted by BEAM.3,Epidata3.0 software was used in entering data and SPSS11.5 was used in statistical analysis,X~2-test and t-test and correlation analysis and principal component analysis and cluster analysis and Unmatched Multiple Logistic Regression and ROC curve were the main methods used in the study.Results 1,The characteristic of demography distribution of CF among Taiyuan city people: removing the chronic disease patients,among 981 people,22.9 percents were CF.Primary Chronic Fatigue people accounted 84.4%(190),and Chronic Fatigue Syndrome accounted 15.6%(35).Different education degree people had different prevalence rate(X2=13.550, P=0.009);and the Unmatched Multiple Logistic Regression showed that high level education (OR=1.253)and mental work(OR=0.696)were the risk factors of CF.2,CF and psychological and social factors:X~2-test and t-test showed that high level education,interpersonal,relationship,load of word or study,gloom,depression and passive coping were risk factors of chronic fatigue,and self-affirmation,objective support. availability of support and positive coping were protect factors.The Unmatched Multiple Logistic Regression showed that high level education and load of work or study were risk factors and self-affirmation and objective support were protect factors.3,CF and personality:Emotional stability factor was protect factor of CF(t=-3.512, P=0.001);and the apprehension(t=3.105,P=0.002)and tension factor(t=5.213,P=0.000) were risk factors.Multiple Logistic Regression showed that tension was risk factor(OR=1.442)4,CF and Reaction Time:The group of CF in students had longer time of simple RT and the slowest reaction speed than the control group.5,CF and EEG:The EEG displayed that the patients of CF in students had lower power of a 1 of left cerebral hemisphere and higher d of left pro-temple and left postnasus.ROC showed that lower power of a 1 had certain diagnosis value to CF,but not sensitivity and specificity. When the power of al of left cerebral hemisphere was 15.0,the sensitivity was 0.63 and the specificity 0.53.Conclusion Psychological and social factors have correlation with Chronic Fatigue.we can improve the life style by health education and health promotion to preventing and descresing the CF prevalence rate;Emotional stability factor was protect factor of CF and the apprehension and tension factor were risk factors.Schools should develop psychological course to preventing the CF prevalence rate and put emphasis on students with tension character;The simple Reaction Time of unhandedness hand may be one of reference to screening CF simply;In EEG, Lower of a i power of left cerebral hemisphere may be one of reference index to diagnose CF.
