Study On The Influence Of Occupational Stress On Autonomic Symptoms Among Station Workers

Objective:The development of the railway industry is the lifeblood of the national economy and affects the well-being of the people.The station workers are important members of the railway staff.The population density of station is highly concentrated,the mobility is large,the environment is noisy,and there are many strict rules and regulations.The work of station staff is monotonous,and it is necessary to work shifts in the night.According to the established procedures,the work must not only deal with various problems of passengers,but also ensure the normal traffic of the trains and maintain the order of the stations.The task of work is even more arduous especially during the peak passenger hours,so the occupational stress of station workers cannot be ignored.In the long-term state of stress,it will affect the normal function of the autonomic nervous system and cause some disorders.Based on the comparison with railway line workers,this study analyzes the occupational stress level and the status of autonomic symptoms of station staff,and discusses the influence of occupational stress on the autonomic symptoms of station workers in combination with demographic characteristics,establishes and validate the structural equation model.Committed to providing a theoretical scientific basis for reducing the severity of autonomic symptoms and preventing the occurrence of occupational stress-related diseases in response to occupational stress-related factors.Methods:A total of 644 staff members of the station under the jurisdiction of the Tianshui Railway CDC were randomly selected as the research object,and 550 railway line workers were used as controls.A total of 1153 valid samples were obtained.The occupational stress of station staff and railway line workers,including occupational stress factors,stress coping strategies,occupational stress outcomes and autonomic symptoms,were investigated through occupational stress measurement tools and composite autonomic symptom scales.Using EXCEL2010 to establish a database,SPSS 19.0 and AMOS 22.0 for statistical analysis,the continuity of normality variables are described in the form of mean and standard deviation,and the data of non-normal distribution are described by median and quartile.T test,Mann-Whitney U test of two independent samples,Kruskal-Wallis H test of multiple independent samples were used to compare,and rank correlation and Logistic regression analysis were used to investigate the effects of occupational stress on autonomic symptoms of station workers.Based on the confirmatory factor analysis of structural equation model,the causal association model between occupational stress and autonomic symptoms of station staff was established.Based on the mediating effect of Bootstrap,the mediating effect of stress coping strategy on the influence of occupational stress on station staff's autonomic symptoms was analyzed.Results:1.The Cronbach's?coefficient in this study is mostly above 0.80,indicating that the internal consistency and reliability of the scale was well.2.There was a statistical difference between the station staff and the railway line workers in occupational stress factors,stress coping strategies,occupational stress outcomes,and autonomic symptoms(P<0.05).3.There were statistical differences in the scores of autonomic symptoms among station staff with different demographic characteristics(P<0.05):(1)There were differences in bladder dysfunction scores among station staff of different gender(P<0.05);(2)The scores of orthostatic intolerance,gastrointestinal dysfunction,bladder dysfunction,pupillary movement disorder and total score of composite autonomic symptoms were statistically different among station workers with different age(P<0.05).(3)The orthostatic intolerance,gastrointestinal dysfunction,bladder dysfunction,pupillary movement disorder and composite autonomic symptom scores of station staff with different marital status were statistically different(P<0.05);(4)The scores of bladder dysfunction of station staff with different education levels were statistically different(P<0.05);(5)There were statistical differences in the orthostatic intolerance,bladder dysfunction,pupillary movement disorder,and composite autonomic symptoms at station workers of different working ages(P<0.05);(6)There is a statistical difference in the scores of bladder dysfunction among station workers in different types of work(P<0.05).(7)The station staff with different work shifting systems had statistical different scores of orthostatic intolerance,vasomotor dysfunction,and the composite autonomic symptoms(P<0.05).4.Analysis of the impact of occupational stress on the autonomic symptoms of station staff:(1)Rank correlation analysis results show:(1)Orthostatic intolerance:There was a positive correlation with work hazard,work needs,group conflicts,intragroup conflicts,job monotony,depression,anxiety,physical complaints,daily tension,emotional exhaustion,personality disintegration and job burnout(P<0.05),which was negatively correlated with physical environment,promotion and participation opportunities,and decreased personal achievement(P<0.05).(2)Vasomotor disorder:work hazard,work demand,group conflict,role ambiguity,work monotony,depression,anxiety,physical complaints,daily tension,emotional exhaustion,personality disintegration,decreased personal achievement,occupational exhaustion was positively correlated(P<0.05),and physical environment,personal accomplishment decreased were negative correlation(P<0.05).(3)Secretory dysfunction:positively related to work hazard,group conflict,intragroup conflict,depression,anxiety,physical complaints,daily tension,emotional exhaustion,personality disintegration,decreased personal accomplishment,occupational exhaustion(P<0.05),negatively correlated with work prospects,physical environment,promotion and participation opportunities(P<0.05).(4)Gastrointestinal dysfunction:work hazard,group conflicts,intragroup conflicts,job monotony,depression,anxiety,physical complaints,daily tension,emotional exhaustion,personality disintegration,decreased personal achievement,and occupational exhaustion were positively correlated(P<0.05),physical environment,promotion and participation opportunities were negative correlation(P<0.05).(5)Bladder dysfunction:there was a positive correlation with work risk,group conflict,intragroup conflict,job monotony,depression,anxiety,physical complaints,daily tension,emotional exhaustion,personality disintegration,decreased personal accomplishment and job burnout(P<0.05),and negative correlation with physical environment(P<0.05).(6)Pupillary disorder:work hazard,work demand,group conflict,intragroup conflict,work monotony,depression,anxiety,physical complaints,daily tension,emotional exhaustion,personality disintegration and occupational exhaustion were positively correlated(P<0.05),and negatively correlated with physical environment and decreased personal accomplishment(P<0.05).(7)Total scores of autonomic symptoms:work hazard,work needs,group conflicts,intragroup conflicts,job monotony,depression,anxiety,physical complaints,daily stress,Emotional exhaustion,depersonalization,reduced personal accomplishment,job burnout was positively correlated(P<0.05),and the physical environment,promotion and opportunities forparticipation,reduced personal accomplishment was negatively correlated(P<0.05).(2)Logistic regression analysis showed:(1)Orthostatic intolerance:work hazard,work load,social support,physical complaints,emotion exhaustion were risk factors,promotion and participation were protective factors(P<0.05).(2)Vasomotor disorder:work hazard,fuzzy character,work monotony,physical complaints,daily tension are risk factors,intragroup conflict is a protective factor(P<0.05).(3)Secretory dysfunction:physical complaints,emotional exhaustion are risk factors,work needs is a protective factor(P<0.05).(4)Gastrointestinal dysfunction:physical complaints,emotional exhaustion are risk factors,work control is a protective factor(P<0.05).(5)Bladder dysfunction:physical complaints,personality disintegration,work hazard are dangerous factors(P<0.05).(6)Pupillary dysfunction:work risk,work monotony,anxiety,physical complaints,job burnout are risk factors,work prospect is a protective factor(P<0.05).(7)Composite autonomic symptoms total score:work hazard,physical complaints and emotional exhaustion were risk factors,physical environment,promotion and participation were protective factors(P<0.05).5.The structural equation model between occupational stress and autonomic symptoms has a good fit and can reflect the influence of occupational stress on the autonomic symptoms of station staff(?~2/df=4.220,GFI=0.934).6.Occupational stress including occupational stress factors,stress coping strategies and occupational stress outcomes had significant effects on the autonomic symptoms of station workers(P<0.01).7.The mediating effect of stress coping strategies in the process of occupational stress on the autonomic symptoms of station workers was significant(P<0.05).Conclusion:The occupational stress level and autonomic symptoms of station staff are different from those of railway line workers;demographic characteristics have some impact on the autonomic symptoms of station workers;occupational stress may lead to the autonomic symptoms of the station staff,the protective factors in occupational stress can relieve the autonomic symptoms of station staff;the stress coping strategy plays a mediating role in the impact of occupational stress on the autonomic symptoms of station workers.
