目的了解煤矿工人高血压前期和高血压的流行现状,探讨职业因素对血压的影响,为制定合理的工作班制和预防煤矿工人高血压提供依据。方法以开滦集团某矿参加健康检查的1 566名井下工人为对象,进行问卷调查并测量血压。结果检出高血压前期患者583人,患病率为37.1%;高血压患者830人,患病率为52.8%。高血压前期患病率随年龄和工龄的延长而降低,高血压患病率随年龄和工龄的延长而升高;掘进工高血压患病率最高,其次为采煤工,井下辅助工最低;三班倒者高血压患病率高于两班倒;上午班者高于下午班;工作时间>8h者高于≤8h者。结论倒班方式是该矿井下工人高血压前期和高血压的职业危险因素;工龄和工种是该矿井下工人高血压的职业危险因素。
Objective To understand the prevalence of prehypertension and hypertension in coal miners and to explore the influence of occupational factors on blood pressure in order to provide a basis for formulating a reasonable work shift system and preventing hypertension in coal miners. Methods A total of 1 566 underground workers who participated in the health check at a mine in Kailuan Group were surveyed and their blood pressure was measured. Results The prehypertensive patients were detected in 583 people, the prevalence was 37.1%; hypertension in 830 people, the prevalence was 52.8%. The prevalence of prehypertension decreased with the increase of age and seniority, the prevalence of hypertension increased with the increase of age and seniority. The prevalence of hypertension in road workers was the highest, followed by coal miners, and the lowest in helpers. The prevalence of hypertension in three shifts was higher than that in two shifts; those in the morning were higher than those in the afternoon; those who worked for more than 8 hours were higher than those who were ≤8 hours. Conclusion Shift is the occupational risk factor of prehypertension and hypertension in underground mine workers. Occupation and work-time are the occupational risk factors of hypertension in underground mine workers.
