三组城市人群心脑血管疾病危险因素流行病学研究

An epidemiologic study on cardiocerebrovascular risk factors in three urban population samples

对北京、上海、长沙三组城市人群基线调查中心脑务管疾病危险因素的平均水平作了对比分析。三组人群中收缩压（ＳＢＰ）均值最高为北京人群１７．２９ｋＰａ（１２９．７０ｍｍＨｇ）（１ｋＰａ＝７．５ｍｍＨｇ），最低为长沙人群１６．６２ｋＰａ（１２４．６７ｍｍＨｇ）。而舒张压（ＤＢＰ）均值最高为长沙人群１０．９０ｋＰａ（８１．７６ｍｍＨｇ），最低为上海人群１０．１２ｋＰａ（７５．９２ｍｍＨｇ）。提示在以往研究中长沙人群在南方城市中有较高的脑卒中发病率与其有较高的ＤＢＰ均值可能有一定的关联。ＢＭＩ与ＴＣ的均值与ＳＢＰ均值在三组人群中的分布趋势一致。三组人群中ＳＢＰ均值均随年龄增长而升高，预防心脑血管疾病应从预防和控制人群高血压入手。

Abstract Cardiocerebrovascular risk factors were investigated in there urban population samples line data analysis showed that mean systolic blood pressure (SBP)was highest in Beijing population(x=129.70mmHg)and lowest in Changsha(x=124.67mmHg).But mean diastolic blood pressure(DBP)was highest in Changsha population(x=81.76mmHg),with Shanghai population the lowest (x=75.92mmHg),It suggested that high DBP in Changsha population was associated with high incidence of stroke there. Mean body mass indes(BMI)and total cholesterol levels were both highest in Beijing and lowest in Changsha.The trends of SBP were similar in three populations.SBP increased with age,hypertension was a serious public health problem in elderly.Therefore, blood pressure control in community should be the first important step in cardiocerebrovascular disease prevention.
