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)

项目摘要：我们在中华人民共和国新疆进行流行病学研究。受试者(100名男性（M)和女性(F)）在50至54岁的居民中随机选择。受试者舒舒服服坐下至少5分钟后，用客观自动血压测量系统测量血压至少3次。24小时尿液用含有防腐剂的等分杯收集，约1/40的总体积冷冻带回日本。受试者以汉族（79 M和66 F）为主，少数民族为维吾尔族、蒙古族、哈萨克族和俄罗斯族（32 M和23 F）。男性组间收缩压、舒张压（SPB、DPB）无显著差异。但F少数群体的SPB高于F多数群体。轻度组交界性高血压（PBH）患病率高于重度组。尿中NaCL和KCL的平均排泄量分别为12.2 0.7 g/d和3.3 0.1 g/d。即使生活在相同的环境条件下，两组之间的PBH也存在差异。这些结果表明，他们的生活方式特别是饮食习惯影响了两组之间的患病率差异。

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.
