| Abstract: |
| 1980年对青藏高原东北部(海拔3050~5188米)青海省的海南、海北、黄南、果洛、玉树五个藏族自治州和海西蒙古族、藏族、哈萨克族自治州的13个县,22个公社的居民,主要为藏族牧民,少数为半农半牧民共8330人的高血压流行病学调查结果表明,高血压患病率2.59%,化率标2.73%,男女无显著差别(P>0.05)。50岁以上的临界高血压患病率1.04%,标化率1.11%。其中藏族患病率低于汉族、蒙古族和回族,而与撒拉族及土族无明显差异。藏族纯牧民患病率低于半农半牧民,标化率之比为2.06%:3.84%。与其它地区藏族的比较表明,标化率青海与甘南无差异(P>0.05)而低于四川甘孜(P<0.01)和西藏拉萨(P<0.001)。分析患病率低发的原因似与长时期适应低氧有关,出现了肺动脉高压和体循环低压。 |

| A survey of hypertension was undertaken among 8,330 people who were mainly Tibetian herdsmen together with a minor proportion of semiagricult-ural-semiherdsmen. They were from 22 people’s communes, 13 counties of Mongolian, Tibetian, Hasakan autonomous states of western Qinghai Province and 5 Tibetian autonomous states in the same province i.e. Hainan, Haibei, Huangnan, Guole, Yushu states. All the above mentioned places are located in Qinghai-Tibet plateau with elevation of 3,050-5,188 meters above sea level. The survey indicated that the morbidity of hypertention was 2.59% and a standardized rate of 2.73%. No difference was found between male and female (P>0.05). The morbidity of borderline hypertension was 1.04% with standardized rate 1.11%. The morbidity in Tibetian nationality is less than that in Han, Mongolian and Musiine nationalities, whereas that between Sala and Tu nationalities showed no significant difference. The morbidity of Tibetian herdsmen was lower than that of semiagricultural-semiherdsmen. The ratio between their standardized rates was found to be 2.06% : 3.48%. when compared with Tibetian populations in other places, the standardized rates between Qinghai and Gannan showed no difference (P>0.0).iNevertheless, it was lower than that of Ganzi, Sichuan(P<0,01) and of Lhasa, Tibet (P<0.001). Analysis of the low morbidity in Tibetian Nationality might permit us to conclude that long-term adaptation in the environment with less oxygen tension might lead to high pulmonary arterial pressure and low systemic pressure. |
