西宁地区102例吸烟者COb及COHb水平分析

An Analysis of Level of COb and COHb in 102 Smokers in Xining Area

目的:通过对吸烟、不吸烟、戒烟人员体内COb、COHb含量进行测定,分析和了解我市吸烟人群体内COHb水平,作为评价吸烟对人体健康危害的参考指标。方法:采集吸烟、不吸烟、戒烟人员的呼出气体分别测定COb,根据COb和COHb含量间的函数关系式计算COHb%含量。结果:吸烟组COHb含量均值为2.36%,超出正常值(2%),戒烟组与不吸烟组含量在正常值范围,(P<0.01);每日吸烟量在10支以上的两个组,COHb含量均超出正常值,分别为2.36%、2.48%,小于10支组在正常值范围,有显著差异(P<0.05);吸烟年数少于10年和10年以上三组间COHb含量均值都超出正常值,分别为2.36%、2.21%、2.45%,差异无显著性(P>0.05)。结论:吸烟组人群体内COHb%含量均值高于正常值,每日吸烟量与体内COHb%含量呈正比关系,长期吸烟者体内COb、COHb含量可持续保持在较高水平,其毒害作用的累积叠加对高原地区吸烟人群的健康影响更为严重。

Objective： To determine the level of COHb of smokers to understand the risk effects of smoking on population in Xiningcity. Methods： The level of Cob in smokers, no-smokers and withdrawal objects was measured respectively and comparably analyzed. Results： The average value of COHb content in smoking group is 2.36% compared with that in the normal value （2%） ; others were in a normal value（P〈 0.01）. In the smokers group, there was a difference between 〉10 cigarettes/day and〈10 cigarettes/day objects （P〈0.05）, but no difference among 〉10 years smoking history and 〈 10years smoking history objects （P〉0.05）. Conclusions： The average value of COHb% content in the smoking group is higher than the normal value. The quantity of smoking every day directly related to COHb% content in the smoking population. Higher level of COb, COHb will still exist in the smoker for a long time.
