Abstract:
Objective:To analyze the relationship between cumulative high temperature exposure and hypertension among steel workers.Methods:We conducted a survey among 7 660 production workers (7 023 males and 637 females) in a large steel mill during February-June 2017 and March-July 2018. Basic information, blood pressure, occupational history and high temperature data in workplace were collected through questionnaire survey, physical measurement and occupational exposure detection. Restrictive cubic spline model was used to analyze the dose-response relationship between cumulative high temperature exposure and hypertension, and the correlation between cumulative high temperature exposure and workers' hypertension was analyzed by logistic regression.Results:The median number of cumulative high temperature exposure was 626.56 ℃·year and 49.20% of workers were exposed to high temperature. The hypertension prevalence rate was 25.60% among the workers. According to the results of the spline model, the cumulative high temperature exposure was divided into three sections: <292.61, 292.61~<720.13, ≥720.13 ℃·year. Taking the exposure <292.61 ℃·year group as a reference, the risk of steel workers' hypertension in the 292.61~<720.13 ℃·year group and ≥720.13 ℃·year group is 1.44 and 2.17 times that of the reference group ( P<0.05) . Conclusion:There was a nonlinear dose-response relationship between cumulative high temperature exposure and steelworkers' hypertension. With the increase of cumulative high temperature exposure, the risk of steelworkers' hypertension increases.
