This study aimed to assess the prevalence of hypertension (HT) among individuals living at different altitudes in Tibet.
We conducted a stratified cluster survey among 1,631 participants in Tibet living in areas at three different altitudes.
Mean systolic and diastolic blood pressure and body mass index (BMI) values were highest at the lowest altitudes. After adjusting for age and sex, the prevalence of HT at low, medium, and high altitudes was 40.6%, 32.5%, and 20.4%, respectively. The prevalence of HT decreased with increasing altitude and increased with increasing age and BMI value.
Increasing altitude tended to decrease BMI levels, and as a consequence, the prevalence of HT was reduced. National policies and guidelines for HT in Tibet should focus on this relationship.
本研究旨在评估西藏不同海拔地区居民的高血压（HT）患病率。
我们对居住在西藏三个不同海拔地区的1631名参与者进行了分层整群调查。
平均收缩压、舒张压及体重指数（BMI）值在最低海拔地区最高。在对年龄和性别进行校正后，低、中、高海拔地区的HT患病率分别为40.6%、32.5%和20.4%。HT患病率随海拔升高而降低，随年龄和BMI值增加而升高。
海拔升高往往会降低BMI水平，因此HT患病率也会降低。西藏高血压的国家政策和指南应关注这种关系。
