Relationship Between Occupational Hazard Exposome And Hypertension In The Steel Workers

Objectives To analyze the relationship between various occupational hazards and steel workers 'hypertension.Reveal that steel workers are exposed to a variety of harmful factors leading to the risk of hypertension,so as to provide a theoretical basis for the prevention and treatment of hypertension in steel workers.Methods To June 2015-June 2016 for occupational health examination of a steel group company working for more than 1 year serving workers as the research object.The relationship between high temperature,noise,dust and carbon monoxide and hypertension was analyzed by using the current research method.At the same time,to analyze occupational risk factors group and the relationship between hypertension,while exposure to a variety of occupational hazards.The questionnaire was conducted by a coherently trained investigator.The survey included demographic characteristics,behavioral lifestyles,personal history and family history,career history,etc.Physical examination: height,weight,blood pressure by a unified training of physicians or nurses to measure.Bying collection of historical data,on-site investigation and interviews to complete the factories' on-site hygiene survey.All data were checked and analyzed,using Epi Data3.1 database,using SPSS20.0,SAS9.1.3 statistical software package for statistical analysis.Single factor analyze the relationship between different demographic characteristics,behavioral lifestyle,two classification data occupational adverse factors and hypertension used ?2 test.Multivariate unconditional logistic regression analysis was used to analyze the multivariate analysis of the relationship between occupational hazards and hypertension.To analyze the relationship between occupational hazardous factors group and hypertension,using logistic regression analysis based on environmental risk scoring,occupational hazardous factors group of workers exposure change to environmental risk score,and then do logistic regression analysis.The relationship between occupational risk factors(ERS)and hypertension was analyzed by restrictive cubic spline combined with logistic regression analysis,and the restrictive cubic spline graph was drawn in SAS.Results 1 The total number of respondents was 8870,and the number of unqualified questionnaires was removed,and the total number used for analysis was 8554.The average age of the subjects was 40.5 ± 8.8 years old,mainly male workers,the proportion of 90.3%;2 suffering from hypertension was 2706,the prevalence rate(95%)of 31.6%(30.6%-32.6%).3 53.1% of the population exposed high temperature;54.9% of the population exposed noise;59.7% of the population exposed dust;47.8% of the population exposed carbon monoxide.4 Univariate analysis showed the proportion of exposured to high temperature,noise,dust,carbon monoxide in the hypertension group was higher than that in the non hypertension group(P<0.001).5 Single occupational hazard model,high temperature,noise,dust,CO using two classification data,Logistic regression analysis,adjust the demographic factors and behavioral lifestyle and other basic covariates,the effects of high temperature,noise,dust and carbon monoxide were independent variables,respectively,and whether hypertension was used as multivariate unconditional logistic regression analysis.The results showed that exposure to high temperature,noise,dust and carbon monoxide the prevalence of hypertension were higher than those without exposure,and the odds ratios were 1.40(1.26-1.55),1.59(1.43-1.76),1.33(1.19-1.47),1.24(1.12-1.37).6 In the multivariate unconditional logistic regression analysis of multiple occupational hazards model,multivariate unconditional logistic regression analysis was carried out by introducing high temperature,noise,dust and carbon monoxide as independent variables.The results showed that exposure to high temperature,noise,dust and carbon monoxide the prevalence of hypertension were higher than those without exposure,and the odds ratios were1.29(1.16-1.43),1.56(1.41-1.74),1.35(1.22-1.50),1.13(1.01-1.25).7 Occupational factors as semi-quantitative data analysis using multivariate unconditional logistic regression analysis of factors affecting hypertension,through a single occupational hazard model and a variety of occupational hazards model selection of statistically significant factors,and they build environmental risk score(ERS)obtained by a single occupational hazard model(ERS1)and multiple occupational hazard factors(ERS2).8 The distribution of ERS in hypertensive and nonhypertensive patients was statistically significant(P<0.001),both ERS1 and ERS2 scored higher in the hypertensive population.9 Restriction Cubic Spline and Logistic Regression Model were used to analyze the doseresponse relationship between environmental risk score and hypertension,the results showed that ERS1 and ERS2 were correlated with hypertension(P<0.05),and there was a linear relationship(non-linear test,P>0.05).With the increase of ERS1 and ERS2,the risk of hypertension was significant Increase the trend.10 After dividing the ERS by five,twofactor multivariate unconditional logistic regression was performed,after adjusting the covariate ERS1 and ERS2 were introduced into Logistic regression model,ERS was the first 20% as the reference,the risk of hypertension was 3.20(2.55-4.02),3.30(2.63-4.13)in the latter 20% of the population.Conclusions 1 high temperature,noise,dust,carbon monoxide and hypertension are related,they are independent risk factor for hypertension.It's impact from small to large size for the noise,high temperature,dust,carbon monoxide.2 Occupational adverse factor group,namely,high temperature,noise,dust,CO combined exposure(ERS)and hypertension have a significant correlation,relative to a single occupational adverse factors,occupational risk factors group of hypertension on the OR value greater.3 With the increase of occupational risk factors combined with cumulative exposure(ERS),the risk of hypertension was significantly increased.4 High risk factors High temperature,noise,dust need to focus on intervention,ERS high risk groups need to focus on intervention.
