International Cooperative Studies Cardiovascular Diseases and for Risk Factor Analysis in the People's Republic of China(Japan-Sino friendship project for prevention stroke and myocardial infarction)

我们在中华人民共和国新疆进行了流行病学调查，在50 - 54岁的居民中随机选择了100名受试者（男，女）。在受试者舒适地坐着至少5分钟后，使用客观自动血压测量系统测量血压至少3次。用装有防腐剂的等分杯收集24小时尿液，约1/40的尿液冷冻带回日本（男性79人，女性66人）和少数民族为维吾尔族、蒙古族、哈萨克族和俄罗斯族（32名男性和23名女性）。男性组之间的收缩压和舒张压（SPB，DPB）没有显著差异。然而，F族SPB高于F族多数，边缘性高血压（PBH）患病率低于F族多数，尿NaCL和KCL平均排泄量分别为12.2 ± 0.7g/d和3.3 ± 0.1g/d，即使生活在相同的环境条件下，两组间PBH患病率差异有统计学意义，提示生活方式尤其是饮食习惯影响两组间PBH患病率的差异。

ABSTRACT OF PROJECT We conducted epidemiological study at Xinjiang in the People's Republic of China.Subjects(100 males(M)and females(F))were chosen at random among inhabitants aged from 50 to 54. Blood pressure was measured at least three times with the objective Automated Blood Pressur Measurement System after the subject had beed sitting comfortably for at least 5 min..Twenty four-hour urine was collected with an aliquot cup containing a preservative agent and about 1/40 of total volume in frozen was brought back Japan.Most of subjects were Han people(79 M and 66 F)and minority were Uighurs,Mongol,Kazak and Russian(32 M and 23 F).There is no significant difference in systolic and diastolic blood pressure(SPB,DPB)between male groups.However,SPB in F minority was higher than that of F majority.Prevalence of borderline hypertension(PBH)was higher in minor group than that of major group.Average urinary excretion of NaCL and KCL were 12.2 0.7 g/day and 3.3 0.1 g/day respectedly.Even though they are living in the same environmental conditions,PBH was difference between two grop.These results suggest that their life style especially dietary custom affect the different prevalence between two group.
