摘　　要：目的:分析吸烟人群24h血压变化的特征。方法:选择2004-05/2004-10在盛京医院体检的健康沈阳市内五区居民482人,根据有无吸烟情况分组后再按相同性别、年龄、身高、体质量、职业1:1配对。共配成115对,吸烟组115人,不吸烟组115人。采用动态血压监测仪监测观察对象的24h及昼夜动态血压变化,日间(6:00～22:00)每15min测试1次,夜间(22:00～次日6:00)每30min测试1次,共记录80次。所采集数据经自动分析后,分别自动打印出24h、日间、上下午和夜间5个时段收缩压、舒张压和心率的平均值。血压昼夜节律判定采用张维忠的动态血压正常值协作研究所规定的标准,既夜间血压平均值比日间下降10%以上称之为杓型改变,夜间血压平均值比日间下降<10%称之为非杓型改变。aχ2=4.158,4.258,4.369,4.298,P<0.05。结果:按意向处理分析,进入结果分析115对,吸烟与不吸烟者分别为115人。①两组除上午平均收缩压、夜间平均收缩压、夜间平均舒张压有明显差异外(P>0.05),其余各时段各项血压指标均有明显差异(t=1.982～2.439,P<0.05)。②在血压昼夜节律形态分布比较中,吸烟组的平均收缩压杓型改变例数、平均舒张压杓型改变例数均明显低于不吸烟组犤33人(28.7%),39人(33.9%);70人(60.9%),78人(67.8%),χ2=4.158,4.369,P<0.05犦。结论:吸烟者白昼常有较高的平均收缩压、舒张压,同时血压昼夜节律中以非杓型改变居多。A IM:To analyze the changing characteris tics of 24-hour blood pressure a-mon g smokers.METHODS:Totally 482healthy physical examin ees,who were the resi dents in the 5districts of Shenyang city,i n the Shengjing Hospital between Ma y and October 2004were divided into groups according to they were smoker or not,and then they were matched one to one with the same gender,age,body heigh t,body mass and job.A total of 115pairs were matched,115cases in the sm oking groups and non-smoking g roup respectively.The changes of th eir24-ho ur blood pressure,and diurnal and nocturnal ambulatory blood pressure were obs erved with the ambulatory bl ood pressure monitor,once every 15minutes in the daytime (6:00to 22:00),and once every 30minutes in the night (2 2:00to the next 6:00),totally 80times were recorded.After the colle cted data were analyzed automa tically,the average values of systo lic pressure ,diastolic and heart rate i n 24hours,daytime,morning,aftern oon and night were printed out automaticall y respectively.The diurnal rhythm o f blood pres sure was judged with the standard made by Zhang' s association for the normal va lue of ambulatory blood pre ssure,that was,nocturnal mean bloo d pressure redu ced by more than 10%as c ompared with the diurnal one was called dipper chang e,and nocturnal mean blood pressure reduced by less than 10%as compared with the diurnal one was called non-dipper change.RESULTS:According to intention -to-treat an alysis,a total of 115pairs were involved in the analysis of r esults,including 115smokers and 115non-smokers.①Except the mean systol ic pressure in the morning and night,and mean diastolic pressure(P>0.05) ,there were obvious differ-ences in the other indexes of blood pr essure at ea ch time segment (t=1.982to 2.439,P<0.05).②In comparison of the distribution of the blood pressure diurnal rhythm form,the nu mbers of cas es had dipper changes for mean systolic pressure and mean diastolic pressure wer e obviously lower in the smoking group than in the non-smo king group33case s(2
