摘要
目的探讨早期预警干预对钢铁企业高温、噪声作业者血压的影响。方法选取河北钢铁集团工人1 306名,其中接触高温、噪声作业者526名为A组,仅接触噪声作业者298名为B组,仅接触高温作业者284名为C组,未接触高温、噪声作业者198名为D组,采用随机数字表法分为两组,一组行常规宣教,一组行早期预警干预,随访2 a后比较各组高血压患病情况。结果随访结束时,D组高血压患病率(3.5%)<C组高血压患病率(12.7%)<B组高血压患病率(26.5%)<A组高血压患病率(41.4%)。D组收缩压(107.4±10.2 mm Hg)<C组收缩压(118.6±11.5 mm Hg)<B组收缩压(132.5±12.6 mm Hg)<A组收缩压(145.3±11.9 mm Hg)。D组舒张压(70.8±4.6 mm Hg)<C组舒张压(77.7±5.8 mm Hg)<B组舒张压(85.2±4.9 mm Hg)<A组舒张压(93.5±6.1 mm Hg)。A、B、C组行分组研究发现,常规宣教组舒张压、收缩压、高血压患病率增加。早期预警干预组舒张压、收缩压、高血压患病率低于常规宣教组。早期预警干预组高血压患病增加人数少于常规宣教组。差异均有统计学意义(均P<0.01)。D组行分组研究发现,随访前后,常规宣教组与早期预警干预组的舒张压、收缩压、高血压患病率的变化不明显。随访结束时,常规宣教组与早期预警干预组的舒张压、收缩压、高血压患病率比较,差异均无统计学意义(均P>0.05)。结论早期预警干预可降低钢铁企业高温、噪声作业者高血压的发生风险。
[Objective] To investigate the influence of early warning intervention on blood pressure of workers exposed to high temperature and noise in steel enterprises. [Methods] 1 306 workers were collected from Flebei Steel Group, including 526 exposed to high temperature and noise in group A, 298 workers exposed to noise in group B, 284 exposed to high temperature in group C,and 198 workers had not been exposed to high temperature and noise in group D. Workers were divided into two groups by random number table method,which received routine propaganda-education and early warning intervention respectively. The prevalence rates of hypertension among groups were compared after 2 years of follow-up. [ Results ] At the end of follow-up,the prevalence rates of hypertension were as follows： group D （3.5%） 〈group C （12.7%） 〈 group B （26.5%）〈 group A （41.4%）, the systolic blood pressure levels were as follows： group D （107.4±10.2 mm Hg） 〈group C （118.6±11.5 mm Hg） 〈 group B （ 132.5±12.6 mm Hg） 〈 group A （ 145.3± 11.9 mm Hg）, and diastolic blood pressure levels were as follows ： group D （70.8±4.6 mm Hg） 〈group C （77.7±5.8 mm Hg） 〈 group B （85.2±4.9 mm Hg）〈 group A （93.5±6.1 mm Hg）. The grouping study on group A, B and C showed that the systolic blood pressure level, diastolic blood pressure level and prevalence rates of hypertension increased in routine propaganda-education group. The systolic blood pressure level,diastolic blood pressure level and prevalence rates of hypertension in early warning intervention group were lower than those in routine propaganda-education group. The in- creased number of hypertension cases in early warning intervention group was less than that in routine propaganda-education group. All differences were statistically significant （all P〈0.01）. The grouping study on group D revealed that the differences in systolic blood pressure level, diastolic blood pressure level and prevalence rates of hypertension were not statistically significant between routine propaganda-education group and early warning intervention group before and after follow-up. At the end of follow-up, there were no statistically significant differences in systolic blood pressure level,diastolic blood pressure level and prevalence rates of hypertension between routine propaganda-education group and early warning intervention group （all P〉0.05）. [ Conclusion l Early warning intervention can reduce the risk of hypertension in workers exposed to high temperature and noise in steel enterprises.
