[Blood pressure level, hypertension prevalence and control status in oldest old in China].

Objective: To investigate blood pressure level, hypertension prevalence and control status in the oldest old in China. Methods: A cross-sectional data set of Chinese Longitudinal and Health Longevity Study (CLHLS) in 2014 was used to investigate the blood pressure level and hypertension prevalence and control status in the oldest old. Results: A total of 4 587 elderly people aged ≥80 years were surveyed with mean age (91.3±7.8) years old, including 1 896 males (41.3%). The mean SBP was (139.5±22.0) mmHg, DBP was (79.6±11.8) mmHg, and the pulse pressure difference was (60.0±18.7) mmHg. The prevalence rate of hypertension was 56.5% (95%CI: 55.1%- 58.0%), the awareness rate of hypertension was 52.2% (95%CI: 50.3%-54.1%), the control rate was 11.5% (95%CI: 10.3%-12.5%), and the control rate of those with awareness of hypertension was 22.2% (95%CI: 19.9%-24.4%). Age, gender, BMI, residence place and living area were related to blood pressure level and control status of the oldest old. Conclusions: The blood pressure level and the prevalence of hypertension in the oldest old in China were different from those in developing countries and adults in China, while similar to that in the younger elderly in China. The prevalence rate of hypertension was high and the control rate was low. Age, gender, BMI, residence place and living area were related with blood pressure level, hypertension prevalence and control status.目的： 探讨我国高龄老年人的血压水平和高血压的患病及控制情况。 方法： 中国老年健康影响因素跟踪调查（Chinese Longitudinal and Health Longevity Study，CLHLS）2014年横断面数据集，探讨血压水平及分布，并开展高龄老年人的高血压患病和控制情况的调查。 结果： 共调查4 587名≥80岁的高龄老年人，年龄（91.3±7.8）岁，其中，男性1 896名，占总人群的41.3%。2014年我国高龄老年人群SBP为（139.5±22.0）mmHg，DBP水平为（79.6±11.8）mmHg，脉压差平均水平为（60.0±18.7）mmHg。高血压患病率为56.5%（95%CI：55.1%~58.0%），知晓率为52.2%（95%CI：50.3%~54.1%），控制率为11.5%（95%CI：10.3%~12.5%），知晓者控制率为22.2%（95%CI：19.9%~24.4%）。年龄、性别、BMI、居住地、来源地区与高龄老年人的血压水平和控制情况有关。 结论： 我国≥80岁高龄老年人血压水平和高血压流行情况与发达国家、我国成年人不同，与年轻老年人结果相差不大。高血压患病率较高而控制率较低，年龄、性别、BMI、居住地、来源地区与血压水平、高血压患病与控制有关。.
