شیوع، آگاهی، درمان و کنترل فشار خون بالا در میان سالمندان چینی: نتایج یک مطالعه مبتنی بر جامعه

The epidemiologic distribution of hypertension among very elderly Chinese is still not clear. This study aimed to investigate the prevalence, awareness, treatment, and control rate of hypertension among very elderly in Chengdu. From May 2013 to May 2015, a total of 1056 participants from 20 residential communities were sampled. Standard face-to-face interviews, physical examinations, and biochemical analysis were undertaken. Participants had a mean age of 83.6 ± 3.4 years (range: 80–100), and 49.8% were men. Mean systolic blood pressure (BP) and diastolic BP were 146.4 ± 20.6 and 74.1 ± 11.9 mm Hg, respectively, and both of the highest BP levels were among participants aged 80–84 years. Mean pulse pressure was 72.5 ± 17.1 mm Hg, and the highest pulse pressure level was among participants aged 90 years and older. The overall estimated hypertension prevalence was 75.3% (95% confidence interval: 72.6%–77.9%), and among overall participants, 51.9% were aware of their hypertensive condition and 45.5% were treated. However, only 18.1% of hypertensive participants were controlled (BP < 140/90 mm Hg). Among very elderly Chinese in Chengdu, the prevalence of hypertension is predominantly high, whereas awareness, treatment, and control rates are considerably low. Effective primary and secondary prevention strategies are needed.
