[Effect of occupational stress on hypertension in desert oilfield workers].

OBJECTIVE

To explore influence of occupational stress on hypertension in Xinjiang Uygur Autonomous Region desert oilfield workers.

METHODS

Cluster sampling was applied. A total of 1280 petroleum workers from 3 oil fields were used in Karamay City, Xinjiang. Occupational Stress Scale(OSI-R) was used to evaluate occupational stress and analyze the impact of occupational stress on hypertension.

RESULTS

With the increase of occupational stress, the prevalence rate of hypertension is increasing(χ~2=21. 078, P<0. 001). Multivariate analysis showed that the risk of high blood pressure in the occupational task was 1. 562 times(95%CI 1. 072-2. 277)as high as that of the less occupational group, and the risk of high blood pressure in the group with strong individual tension reaction was 1. 701 times(95%CI 1. 158-2. 498)as much as that of the weak group(P<0. 05). Analysis of influencing factors of hypertension showed that the risk of high blood pressure in the shift was 1. 389 times(95%CI 1. 115-1. 730)as high as those without the shift, in the frequent drinkers was 1. 877 times(95%CI 1. 300-2. 710)that of the non drinkers, in the high salt patients was 1. 286 times(95%CI 1. 107-1. 691)that of the low salt, in the obese was 1. 564 times(95%CI 1. 249-2. 216)that of the normal people, and in the highly occupational stress was 1. 976 times(95%CI 1. 641-2. 336)as high as the low occupational stress.

CONCLUSION

Heavy occupational tasks and strong individual strain can increase the risk of hypertension in desert oilfield workers. Shift, drinking history, salt consumption, BMI and occupational stress were the influencing factors of hypertension in desert oilfield workers.
