Abstract:

Objective To understand the prevalence of hypertension in coal miners and analyze its influ⁃encing factors. Methods From April 2017 to June 2017，we selected 652 male coal miners from a state⁃ownedenterprise in Shanxi Province as research subjects. Hypertension was determined according to the diagnostic criteriaof the 2010 Chinese guidelines for the prevention and treatment of hypertension. The concentrations of 4 PAHsmetabolites in urine were determined by HPLC. The influencing factors of hypertension in coal miners were analyzedby chi⁃square test，Wilcoxon rank⁃sum test and multivariate logistic regression model. Results The overall prevalenceof hypertension among coal miners was 33.7%. Wilcoxon rank⁃sum test showed that there was no statisticallysignificant difference in the level of urinary PAHs metabolites between the groups of normal blood pressure andhypertension（P > 0.05）. Logistic regression analysis showed that age > 40，alcohol consumption，overweight andobesity were all risk factors for hypertension in coal miners and the protective factors of hypertension in coal mineworkers were the underground first⁃line work and underground auxiliary job. Conclusion No association is foundbetween urinary PAHs metabolites and hypertension. Coal miners aged over 40 years，with BMI ≥ 24 kg/m2，andpoor living habits have a higher risk of hypertension. Health education and daily monitoring of such people shouldbe strengthened.
