Trends in Blood Pressure and Prevalence of Hypertension in Korean Adults Based on the 1998-2014 KNHANES.

ABSTRACT:

Purpose

To investigate trends in blood pressure (BP) and hypertension prevalence in Korea.

Materials and methods

Based on the Korean National Health and Nutrition Examination Survey (KNHANES) I (1998), II (2001), III (2005), IV (2007-2009), V (2010-2012), and VI (2013-2014), 56077 participants (23974 men and 32103 women) were included.

Results

Mean systolic BP (SBP) and diastolic BP (DBP) decreased in both sexes (male SBP: 128.1 to 120.2 mm Hg, male DBP: 82.0 to 78.5 mm Hg; female SBP: 125.7 to 116.0 mm Hg and female DBP: 77.4 to 73.2 mm Hg from the KNHANES I-VI). The age-standardized prevalence of hypertension was significantly decreased in both sexes (male; 33.3% to 30.3%, female; 28.7% to 22.7%, all p for trend <0.001). Regardless of taking anti-hypertensive medication or not, SBP and DBP declined universally in both sexes. Compared to the KNHANES I, the odds ratios (95% confidence intervals) of the KNHANES II to VI for less-than-normotensive and less-than-hypertensive BP increased in both sexes.

Conclusion

Mean BP levels in both sexes and hypertension prevalence showed downward trends during the 16-year period.
