高海拔地区的血压（BP）研究很少，结果存在争议。藏族人生活在高海拔地区，高血压患病率的数据在这一人群目前还不是很清楚. METHODS所有藏族人年龄在40岁及以上的生活在西藏羊八井乡（4,300米），中国被邀请参加2009年的调查。使用电子血压计（根据先前研究结果校准）测量血压。通过面对面访谈收集高血压病史和药物使用情况。高血压定义为收缩压（SBP）≥ 140 mm Hg和/或舒张压（DBP）≥ 90 mm Hg，或在过去2周内使用降压药物。平均值（s.d.）SBP/DBP为146.6（31.3）/92.0（15.7）mm Hg，高血压患病率为55.9%。值得注意的是，61.2%的高血压患者患有2级高血压（SBP >= 160或DBP >= 100 mm Hg）。在70岁及以上时，平均值（s.d.）SBP/DBP为182.8（30.9）/102.6（13.4）mmHg。在高血压患者（n = 392）中，只有19.9%的人知道自己的病情，2.6%的人正在服用药物，只有一名参与者控制了BP.CONCLUSIONAccording to our survey in Yangbajing，藏族成年人年龄在40岁及以上，生活在高海拔地区有高血压和高血压的患病率低的认识，治疗和控制。未来的研究需要澄清血压，海拔和其他可能原因之间的联系。
BACKGROUNDStudies on blood pressure (BP) in high-altitude areas are scarce and the results are controversial. Tibetans live in regions at high altitudes, and data on the prevalence of hypertension in this population is not currently well known.METHODSAll Tibetans aged 40 years and older living in the township of Yangbajing (4,300 m) in Tibet, China were invited to participate in the 2009 survey. BP was measured with electronic sphygmomanometers (calibrated by the results of a previous study). Histories of hypertension and medication use were collected through face-to-face interviews. Hypertension was defined as systolic BP (SBP) >= 140 mm Hg and/or diastolic BP (DBP) >= 90 mm Hg, or antihypertensive medication use in the past 2 weeks.RESULTSA total of 701 adults (aged 40-89, 42.9% male, 94.9% herdsmen) were recruited. The mean (s.d.) SBP/DBP was 146.6 (31.3)/92.0 (15.7) mm Hg and the prevalence of hypertension was 55.9%. Of note, 61.2% of those with hypertension had stage 2 hypertension (SBP >= 160 or DBP >= 100 mm Hg). At age 70 years and older, the mean (s.d.) SBP/DBP were 182.8 (30.9)/102.6 (13.4) mm Hg. Among those with hypertension (n = 392), only 19.9% were aware of their condition, 2.6% were taking medication, and only one participant had controlled BP.CONCLUSIONAccording to our survey in Yangbajing, Tibetan adults aged 40 years and older living at high altitudes had high BP and prevalence of hypertension with low awareness, treatment, and control. Future studies are needed to clarify the association between BP, altitude, and other possible causes.
