【摘要】 目的　探讨人群收缩压、舒张压均数变化规律以及有关因素对血压水平的影响 ,为预防控制高血压提供资料。　方法　采取分层整群抽样法 ,抽取 15岁以上的城乡居民进行血压、身高、体重测量及问卷调查 ,共调查城乡居民6665人。　结果　人群收缩压均数随年龄组递增而升高 (P <0 .0 1) ,15岁至 75岁组共升高 40 .4mmHg ,升高幅度以 3 5岁以上的组段为大。人群舒张压亦随年龄递增而升高 (P <0 .0 1) ,升高幅度较大的年龄为 3 5～ 5 0岁 ,共升高 5 .4mmHg。人群血压水平的城乡差异主要见于 45～ 65岁间的收缩压 ,城市高于农村。性别差异出现在 45岁以前 ,男性高于女性。超重肥胖对血压升高作用大于有高血压家族史者。各年龄组收缩压、舒张压均数均随BMI增大而升高 ,呈显著正相关 (P<0 .0 1)。　结论　人群血压上升幅度从 3 5岁起显著增大。控制体重、防止肥胖对于降低人群血压水平 .预防高血压发生具有重要作用更多还原

【Abstract】 Objective To explore the regular pattern of blood pressure change and risk factors on blood pressure level. To provide a basis for hypertention prevention and control. Methods A total of 6665 subjects aged 15 and over in urban and rural areas were selected with stratified and cluster sampling.Blood pressure, height and weight measurement, interview,questionnaire were adopted in this survey. Result The mean of systolic blood pressure(SBP) increased with age in community population (P<0.01), rised totally 40.4mmHg in 15～75 years old and highest in 35 years and over age group. The mean of diastolic blood pressure (DBP) increased with age too(P<0.01), rised 5.4mmHg and highest in 35～50 years old age group. The difference between urban and rural areas was seen in SBP in 4～65 years old age group, the urban area was higher than rural. Gender difference was displayed before 45, male was higher than female. The overweight-obesity effect on increase of BP was higher than family hypertension history. The mean of SBP and DBP increased with BMI in each age group, with significant positive correlation(P<0.01). Conclusion The increase of BP mean over 35 years of age was significantly higher than that under 35. Body weight control plays an important role in lowering blood pressure level and hypertension prevention.更多还原
