Hypertension is the most important risk factor for cardiovascular diseases and overall mortality. This study aimed to report the temporal trends in hypertension prevalence, awareness, treatment, and control in Korea from 1998 to 2015.Methods:
Data from 113,053 subjects aged 30 years or older in the Korea National Health and Nutrition Examination Survey, a nationally representative survey, were used to identify the rates of hypertension prevalence, awareness, treatment, and control.Results:
The prevalence of hypertension was 30.5% (95% confidence interval [CI], 29.3–31.7%) among Koreans aged 30 years or older, which remained grossly unchanged between 1998 and 2015. Hypertension was more prevalent among the elderly and men. Among the hypertensive subjects, 67.3% (95% CI, 65.4–69.1%) were aware of the diagnosis, 63.6% (95% CI, 61.7–65.4%) received treatment, and 46.2% (95% CI, 44.3–48.1%) had adequately controlled blood pressure during the period of 2013–2015. The awareness, treatment, and control rates showed remarkable improvement (23.5 to 66.3%, 20.4 to 60.3%, and 4.9 to 42.1%, respectively) from 1998 to the period of 2007–2009, at which point the numbers plateaued and showed no further significant changes. Moreover, among hypertensive subjects who were young and male, the awareness, treatment, and control rates remained low.Conclusion:
The overall prevalence of hypertension (30.5%) in Korea remained stable from 1998 to 2015. The awareness, treatment, and control of hypertension remarkably improved during the study period; however, the detection and management were suboptimal among hypertensive subjects who were young and male, which suggests that there is still room for improvement.
