Objective To analyze hypertension status and related impact factors in steel workers, and to provide scientific basis for controlling their risk of hypertension.
Methods Male front-line workers (n=908) of a steel enterprise in Tangshan city were selected for observation group; male administrators and supporting crew (n=609) were selected for control group. Unified questionnaires were delivered to collect information on health status. Blood pressure levels were measured by standard method. High temperature and noise were monitored in accordance with the national standards. SPSS 13.0 was applied to statistical analysis. Single factor and multiple factor regression analyses were conducted to evaluate selected impact factors of hypertension in steel workers.
Results The hypertension prevalence rate in the observation group (44.1%) was higher than that of the control group (34.7%)(P<0.05). After stratified by blood pressure level and age, both the prevalence rates of normal high blood pressure and hypertension (46.4% and 41.5%) in the observation group were higher than those in the control group (41.6% and 38.8%). Especially in the 30-39 age group, the prevalence rates of normal high blood pressure and hypertension (51.0% and 36.5%, respectively) in the observation group were statistically higher than those in the control group (46.0% and 32.3%, respectively)(P<0.05). High temperature and noise, body mass index (BMI), and drinking were the risk factors for elevated blood pressure in steel workers. BMI, fried food intake, drinking, family history of hypertension, smoking, and exposure to high temperature and noise were the risk factors of hypertension.
Conclusion Adiposity, fried food, drinking, family history of hypertension, smoking, and exposure to high temperature and noise may increase the risk of hypertension in steel workers.
