| Objective: This study will conduct a questionnaire survey on employees of petrochemical enterprises,describe the occupational stress level and prevalence of employees in petrochemical enterprises,analyze its influencing factors and the health effects of occupational stress,and explore the sources of occupational stress of petrochemical enterprise employees.Provide basis for prevention and control strategies.Methods: Using the cluster sampling method,a self-filled questionnaire survey was conducted among 1,888 employees in different workshops of a petrochemical enterprise in Liaoning Province.Use the Effort-Reward Imbalance Questionnaire(ERI),Perceived Work Environment Questionnaire(PWE),Depression Self-Rating Scale(CES-D),and health examinations to influence employees’ occupational stress,occupational environment,depression status,hypertension,diabetes,and Investigate related factors such as the prevalence of dyslipidemia.Divide occupational stress into high-level and low-level groups,and analyze the influencing factors of occupational stress and its health effects.The results were analyzed by t-test,single-factor analysis of variance,chi-square test,multi-factor Logistic regression analysis and interaction analysis.Results:1.Questionnaire survey results: A total of 1888 questionnaires were distributed and recovered in this study,of which 1521 were valid questionnaires,and the effective recovery rate was 80.56%.Among all survey subjects,1284 were males(84.4%)and 237 were females(15.6%);the average age was(42.9±9.1)years;the detection rate of occupational stress among petrochemical employees was 22.7%(346/1521);depression symptoms occurred The prevalence rate was 63.7%(969/1521);the prevalence rate of hypertension was 33.5%(510/1521);the prevalence rate of diabetes was 10.6%(161/1521);the prevalence rate of hypercholesterolemia was 10.6%(161/521).1521);the prevalence of hypertriglyceridemia is 22%(334/1521);the prevalence of low-high-density lipoproteinemia is 25.1%(382/1521);the prevalence of low-density lipoprotein abnormalities is 16.0 %(244/1521).2.Reliability and validity test results: The Cronbach’sα of the Unbalanced Payback Questionnaire,the Perceived Work Environment Questionnaire,and the Depression Self-Rating Scale are 0.854,0.803,and 0.935,respectively.The Cronbach’s α of the three dimensions of the pay-return imbalance questionnaire are 0.756,0.875 and 0.787 respectively.And they all have good structure validity.3.Single factor analysis results: 1)Influencing factors of the pay-return ratio include: age,education level,BMI classification,weekly working hours,type of work,night shift,fixed shift,sleep quality and occupational environmental factors(P<0.05);2)intrinsic Influencing factors of investment score include: education level,position,weekly working hours,type of work,night shift,sleep quality and occupational environment factors(P<0.05);3)Influencing factors of occupational stress level include: age,education level,BMI classification,Weekly working hours,length of service,type of work,night shift,fixed shift,physical exercise,sleep quality and occupational environment factors(P<0.05);4)The influencing factors of occupational stress classification include: marital status,monthly income,position,Weekly working hours,type of work,night shift,fixed shift,sleep quality and occupational environmental factors(P<0.05).4.Multivariate analysis Logistic results: BMI classification(OR=1.966,95%CI=1.254～3.084),position(OR=0.630,95%CI=0.422～0.939),weekly working hours(OR=1.404,95%CI=1.078～1.829),type of work(OR=1.952,95%CI=1.221～3.112),night shift(OR=2.452,95%CI=1.642～3.662),sleep quality(OR=2.016,95%CI=1.487～2.731),Noise exposure(OR=2.452,95%CI=1.565～3.814),high temperature operation(OR=1.968,95%CI=1.285～3.013)and hazardous operation(OR=2.522,95%CI=1.535～4.144)are Independent influencing factors of high occupational stress among petrochemical employees.5.Interaction analysis results: there is an interaction between age<35 years old and marital status being married/cohabiting(OR=1.616,95%CI=1.122～2.328);there is an interaction between age<35 years old and non-fixed classes(OR=2.083,95%CI=1.494～2.906);there is an interaction between age<35 years old and exposure to strong light(OR=2.847,95%CI=1.916～4.233);marital status is married/cohabiting and education level There is an interaction between high school and below(OR=0.759,95%CI=0.593～0.971);there is an interaction between marital status being married/cohabiting and working experience less than 10 years(OR=1.572,95%CI=1.175～2.103);marital status is the interaction between married/cohabiting and non-fixed classes(OR=1.452,95%CI=1.138～1.852);there is an interaction between working experience less than 10 years and non-fixed classes(OR=1.734,95%CI=1.260～2.387);there is an interaction between strong light exposure and high dust exposure(OR=3.830,95%CI=2.631～5.576);there is an interaction between high dust exposure and exposure to toxic and hazardous substances(OR=2.875,95%CI=2.131～3.878).6.The results of the analysis of the health effects of occupational stress: the incidence of depression,hypertension,and dyslipidemia in the high-level occupational stress group were higher than those in the low-level occupational stress group.Conclusion:1.Body mass index(BMI),position,weekly working hours,type of work,night shift,sleep quality,noise exposure,high temperature work,and hazardous work are the influencing factors of occupational stress for petrochemical employees.2.Among the influencing factors of occupational stress in petrochemical enterprises,age and marital status,nonfixed classes,and high light exposure;marital status and education level,working age,non-fixed classes;working years and non-fixed classes;strong light exposure and high dust exposure and high exposure There is an interaction between dust exposure and exposure to toxic and hazardous substances.3.High occupational stress increases the risk of depressive symptoms,hypertension and dyslipidemia among petrochemical employees. |
