Blood pressure level, hypertension prevalence and control status in oldest old in China / 中华流行病学杂志

ABSTRACT

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.
