Key result
China reference yields ~26% lower HBP prevalence compared to US guidelines.
Why the study?
The study aimed to compare the performance of the China reference with different national and international references for defining high blood pressure in children and adolescents.
Does the choice of blood pressure reference (China vs U.S., international, Europe) affect the estimated prevalence of high blood pressure in Chinese children and adolescents?
Population
695,302 children and adolescents aged 7 to 17 years in Suzhou, China
Comparison

Reference choice substantially alters high BP prevalence estimates in Chinese youth; leaves open optimal standard for outcomes.

Does the choice of blood pressure reference (China vs U.S., international, Europe) affect the estimated prevalence of high blood pressure in Chinese children and adolescents?
Absolute Event Rate: 19.2% vs 26%
p-value: p=<0.001
The estimated prevalence of high blood pressure in Chinese children varies significantly depending on the reference standard used, highlighting the importance of appropriate reference selection.
Zhang et al. (2021) conducted a cross-sectional in High blood pressure (n=695,302). China reference for high blood pressure vs. U.S., international, and Europe references was evaluated on Prevalence of high blood pressure (p=<0.001). High blood pressure prevalence using the China reference was 19.2%, significantly lower than estimates using U.S. (26.0%), international (20.0%), or Europe (19.5%) references (P<0.001).
