| Objectives To understand the prevalence of nailfold microcirculation disorders in petroleum workers,and evaluate the risk of nailfold microcirculation disorders caused by exposure to a variety of harmful factors in order to provide the scientific basis for reducing the occurrence of nailfold microcirculation disorders.Methods In this study,the petroleum workers who participated in the occupational health examination from May to October 2018 and worked for more than one year were selected as the research objects.The relationship between cardiovascular disease factors,occupational harmful factors and microcirculation disorders was analyzed by current situation study,and the risk factors of nailfold microcirculation disorders were screened.A questionnaire survey was conducted using the "Health Assessment Form" designed by the research team,and a face-to-face questionnaire survey was conducted by graduate students from North China University of Science and Technology,which included: social demographic data such as gender,age,education level,life behavior habits such as smoking,drinking,and physical exercise,occupational factors such as shift work,and noise exposure history.The physical examination and blood biochemical examination data were also collected.A third-party organization with testing qualifications measured the onsite hygienic data of the petroleum workers.Statistical analysis was performed using SPSS 23.0 software.The measurement data was described by the mean ± standard deviation.The count data was expressed as a composition ratio or rate,and the ?2 test is used for comparison between groups.Unconditional Logistic regression model was used to analyze the risk factors of nailfold microcirculation disorder in petroleum workers.Results 1 A total of 1112 petroleum workers were surveyed.With 64 incomplete data excluded,1048 was included.The age range of petroleum workers was 19-62 years and the number of 40-50 years was the largest accounting for 54.6%.The incidence of nailfold microcirculation disorders was 32.6%.2 Single factor analysis show that: 1)The incidence of microcirculation disorder of male,unmarried,college and above groups were higher than that of their respective control group(P<0.001).2)With the increase of age,the incidence of nailfold microcirculation in petroleum workers decreased(linear trend chi square value was 33.448,P<0.001);with the increase of BMI,the incidence of nailfold microcirculation increased(linear trend chi square value was 8.683,P<0.05).3)The risks of nailfold microcirculation disorder in petroleum workers who smoke,drink,physical exercise was 1.329,1.326,and 0.595 times than that of respective control group.4)The risk of nailfold microcirculation disorder in petroleum workers with hypertension,hyperglycemia and hyperlipidemia was 1.626,1.841 and 1.419 times higher than that of respective control group.5)The incidence of nailfold microcirculation disorders in petroleum workers who exposed to noise and high temperature was 39.9% and 39.7%,which was higher than that of respective control group.The incidence of nailfold microcirculation disorders in petroleum workers on shift work was 37.9%,which was higher than the control group(27.7%).3 In single cardiovascular disease model,took whether there was microcirculation disturbance as dependent variable,and took hypertension,hyperglycemia,hyperlipidemia using two classification data as independent variables.After adjusting social demographics and lifestyle habits,the results showed that petroleum workers with high blood pressure and hyperglycemia had a higher risk of nailfold microcirculation disorder than respective control group,and their OR(95%CI)results were 1.63(1.23?2.17)and 1.66(1.25?2.22).In a variety of cardiovascular disease models,took whether there was microcirculation disturbance as dependent variable,and hypertension,hyperglycemia,and hyperlipidemia were simultaneously included as independent variables in the model.The results showed that petroleum workers with high blood pressure and hyperglycemia had a higher risk of nailfold microcirculation disorder than respective control group,and their OR(95%CI)results were 1.57(1.18?2.09)and 1.56(1.16?2.10).4 In the single occupational harmful factors model,took whether there was microcirculation disturbance as dependent variable,and took noise,high temperature,and shift work using binary data as independent variables,and then adjusted the social demographics and lifestyle behavior factors.The results showed that petroleum workers with noise,high temperature,shift work had a higher risk of nailfold microcirculation disorder than respective control group and their OR(95%CI)results were 1.79(1.35?2.38),1.86(1.41?2.46)and 1.45(1.10?1.92)respectively.In a variety of occupational harmful factors,took whether there was microcirculation disturbance as dependent variable,and noise,high temperature and shift work were simultaneously included as independent variables.The results showed that petroleum workers with noise and high temperature had a higher risk of nailfold microcirculation disorder than respective control group,and their OR(95%CI)were 1.27(1.12?1.53)and 1.50(1.06?2.14).5 Taking whether there was microcirculation disturbance as dependent variable,all variables with statistical significance in Chi square test were included in the model.The results showed that compared with petroleum workers of men,under 30 years old,and without physical exercise,female,over 50 years old and physical exercise had a lower risk of nailfold microcirculation disorder,and their OR(95%CI)were 0.69(0.51?0.95),0.40(0.20?0.82)and 0.68(0.51?0.900).Petroleum workers with high blood pressure and hyperglycemia had a higher risk of nailfold microcirculation disorder than respective control group,and their OR(95%CI)were 1.73(1.29?2.31)and 1.68(1.25?2.28).Petroleum workers with noise,high temperature had a higher risk of nailfold microcirculation disorder than respective control group and their OR(95%CI)were 1.53(1.07?2.19)and 1.49(1.03?2.15).Conclusions 1 The prevalence of nailfold microcirculation disorders in petroleum workers was 32.6%.2 Male,high temperature,noise,hypertension,and hyperglycemia were the risk factors of nailfold microcirculation disorder in petroleum workers.Physical exercise was a protective factor for nailfold microcirculation disorder.Figure 7;Table 11;Reference 147... |
