Supports narrowing BP inequities in Korean men; cross-sectional design leaves causality and generalizability open.
Cross-Sectional (n=56,873)
From 2005 to 2015, blood pressure levels decreased across most economic strata in Korea, narrowing health inequities, particularly among men.
Shin et al. (2018) conducted a cross-sectional in Blood pressure (n=56,873). Economic status (house income quartile) vs. Across income quartiles was evaluated on Trends in systolic and diastolic blood pressure. Between 2005 and 2015, systolic and diastolic blood pressure decreased significantly across most income quartiles in Korea, narrowing the gap in health inequities, particularly in men.
