A prevalence study on occupational stress and hypertension among steel production workers / 中国职业医学

ABSTRACT

OBJECTIVE: To analyze the correlation between occupational stress and hypertension in steel production workers.METHODS: By the stratified cluster sampling method,1 580 steel production workers from an iron and steel group company were selected as study subjects. Occupational stress was measured by the Chinese version of Job Content Questionnaire.The identification of having occupational stress was the ratio of job requirement dimension score over job self-decision dimension score turned to be ≥1. 00. The steel production workers' blood pressure was measured by the updated mercury sphygmomanometer. The effect of occupational stress on blood pressure in steel production workers was analyzed. RESULTS: The dimension score of job self-decision in hypertension group was lower than that in non-hypertension group [20( 16,23) vs 20( 17,24) scores,P < 0. 05]. There was no statistical significant difference in occupational stress ratio,job requirement and social support dimension scores between two groups( P > 0. 05). The multiple logistic regression analysis showed that job self-decision and social support scores were negatively correlated with the incidence of hypertension [odds ratios( 95% confidence intervals) were 0. 68( 0. 51,0. 90) and 0. 54( 0. 45,0. 76),P < 0. 01]. CONCLUSION: Job selfdecision and social support are the influencing factors of the incidence of hypertension in steel production workers. The correlation among occupational stress,job requirement and hypertension are not found in steel production workers.
