Key result
Hypertension prevalence among the Chinese oldest-old climbs ~31% between 1998 and 2014.
Why the study?
There were little national data on hypertension in the oldest-old and a lack of information on chronological changes.
Cross-Sectional (n=63,362)
Yes
Absolute Event Rate: 56.5% vs 43.1%
p-value: p=<0.001
There was a significant increase in hypertension prevalence among the oldest-old population in China from 1998 to 2014, highlighting the need for targeted prevention efforts.
Rising hypertension prevalence in Chinese oldest-old may warrant closer monitoring; leaves open drivers and optimal prevention strategies.
BACKGROUND: There were little national data on hypertension based on the oldest-old, and lack of information on chronological changes. This study aimed to describe trends of blood pressure (BP) levels and hypertension prevalence for the past 16 years among the oldest-old in China. METHODS: All the oldest-old who had participated in the Chinese Longitudinal Healthy Longevity Survey (CLHLS) 1998 to 2014 with information about BP levels and hypertension were included in the analysis. RESULTS: There was fluctuation over the past 16 years for both SBP and DBP levels. The mean SBP level decreased from 148.4 ± 24.4 mmHg in 1998 to 130.8 ± 18.7 mmHg in 2005, and then increased to 139.7 ± 22.0 mmHg in 2014. The mean DBP level decreased from 84.3 ± 13.4 mmHg in 1998 to 78.9 ± 11.7 mmHg in 2008, and then increased to 79.7 ± 11.8 mmHg in 2014. The hypertension prevalence increased from 43.1 to 56.5% for the 16 years. The prevalence of isolated systolic hypertension was lowest in 2002-2005 (14.3%), and then increased to 30.7% in 2014. Multivariate logistic regression showed that older age, lower education and economic level, without health insurance were associated with higher hypertension prevalence. CONCLUSIONS: There was a significant increase in hypertension prevalence among the Chinese oldest-old from 1998 to 2014. Greater efforts are needed for hypertension prevention among this specific population.

Du et al. (2019) conducted a cross-sectional in Hypertension (n=63,362). Survey year 2014 vs. Survey year 1998 was evaluated on Hypertension prevalence (p=<0.001). The prevalence of hypertension among the Chinese oldest-old increased significantly from 43.1% in 1998 to 56.5% in 2014.
