Abstract：Objective To explore the influence of heat and noise exposure on the risk of hypertension in workers,and to provide evidence for prevention of hypertension in occupational population. Methods Cluster sampling method was used to recruit 2 130 steel workers from four factories（north iron-making,long steel,cold steel and power department）of some steel company. A cross-sectional study was conducted to collect physical examination results,heat and noise exposure. Logistic regression models were used to analyze the effects of noise,heat and their interaction on hypertension. Results Totally 1 971 valid questionnaires were collected,and the response rate was 92.54%. There were 654 workers suffering from hypertension,with a prevalence rate of 33.18%. There were 1 006 workers exposed to noise,accounting for 51.04%;and 853 workers exposed to heat,accounting for 43.28%. The prevalence rates of hypertension in workers exposed to noise and heat were higher than those in workers without the above exposure（P<0.05）. The prevalence rates of hypertension increased with the increase of age and working years（P<0.05）. The results of multivariate logistic regression analysis showed that noise（OR=1.711,95%CI：1.380-2.121）,heat（OR=1.721,95%CI：1.394-2.125）were risk factors for hypertension;the interaction between noise and heat on hypertension was not statistically significant（P>0.05）,while the interaction between noise and age（OR=1.086,95%CI：1.057-1.115）,between heat and age（OR=1.087,95%CI：1.059-1.115）both increased the risk of hypertension. Conclusion Occupational exposure to heat and noise are risk factors for hypertension. These two occupational hazards also interact with age,which can increase the risk of hypertension in workers.
