目的探讨煤矿工人Hb含量与血压水平的相关性。方法以邯郸地区某煤矿2 375名煤矿工人为研究对象。测量收缩压(SDP)和舒张压(DBP)。根据其血压水平分为3组:正常血压组(SBP<120mm Hg、DBP<80mm Hg)957例,高血压前期(SBP:120~139mm Hg、DBP:80~89 mm Hg)961例,高血压组(SBP≥140mm Hg、DBP≥90 mm Hg)457例;根据Hb四分位法将研究对象分为4组,即A组:Hb<142g/L;B组:142g/L≤Hb<148g/L;C组:148g/L≤Hb<155g/L;D组:Hb≥155g/L,对数据进行统计分析。结果随着血压的逐渐升高,Hb含量有明显上升趋势,正常血压组(146.53±9.75)g/L、高血压前期(148.99±9.69)g/L,高血压组(150.05±9.79)g/L组间比较,差异有统计学意义(P<0.05)。Hb含量四分位C及D组的SBP、DBP水平高于A、B组,且差异有统计学意义(P<0.05)。Pearson相关分析显示,Hb含量与SBP、DBP等均呈显著正相关。结论该人群随着血压的水平升高外周Hb水平呈逐渐上升的趋势,Hb水平的升高可能增加高血压或高血压前期的发病率。
Objective To explore the correlation between Hb content and blood pressure level in coal miners. Methods A total of 2 375 mine workers from a coal mine in Handan area were selected as research objects. Systolic blood pressure (SDP) and diastolic blood pressure (DBP) were measured. According to their blood pressure levels, they were divided into three groups: 957 cases of normotensive group (SBP <120 mm Hg, DBP <80 mm Hg), 961 cases of prehypertension (SBP: 120- 139 mm Hg, DBP: 80-89 mm Hg) (SBP≥140mm Hg, DBP≥90 mm Hg) were divided into four groups according to the Hb quartile method: group A: Hb <142g / L; group B: 142g / L≤Hb <148g / L; C group: 148g / L≤Hb <155g / L; D group: Hb≥155g / L, the data were statistically analyzed. Results With the gradual increase of blood pressure, the content of Hb increased obviously. The levels of Hb in normal group (146.53 ± 9.75) g / L, prehypertension group (148.99 ± 9.69) g / L, hypertension group (150.05 ± 9.79) g / L group, the difference was statistically significant (P <0.05). SBP and DBP levels in C and D groups with Hb content were higher than those in A and B groups, and the difference was statistically significant (P <0.05). Pearson correlation analysis showed that there was a significant positive correlation between Hb content and SBP and DBP. Conclusion The peripheral blood Hb levels in this population gradually increase with the increase of blood pressure level. The increase of Hb level may increase the incidence of hypertension or prehypertension.
