title: A trend analysis of the prevalence, awareness, treatment, and control of hypertension by age group.
abstract: OBJECTIVE
  We examined the trends in prevalence, awareness, treatment, and control of hypertension in Korea as a basis for improving hypertension control programs.
  
  
  METHODS
  12 598 participants of the Korean National Health and Nutrition Examination Survey were included in this study. Weighted linear regression to test time trends from 2007 to 2011 was performed.
  
  
  RESULTS
  The prevalence of hypertension was 20.7% in 2007, 29.4% in 2009, and 26.2% in 2011. Awareness of hypertension was 64.8% in 2007 and 61.1% in 2011. Awareness in those aged 65 and over was greater than in younger groups (age 19 to 44 and 45 to 64; p<0.001). The treatment rates were 58.4% in 2007 and 56.8% in 2011. The treatment rate was greater for those 65 and over than for younger age groups (p<0.001). The percentage of controlled hypertension was 37.6% in 2011. The percentage of controlled hypertension in those 65 and over was higher than in younger age groups (p<0.001). The treatment-control rates were 65.9% in 2007 and 67.7% in 2011. The prevalence of hypertension was higher in the males (p<0.001), while the awareness (p<0.001), treatment (p<0.001), and control (p<0.001) rates were higher in the females.
  
  
  CONCLUSIONS
  The prevalence of hypertension was increasing and the hypertension awareness, treatment, and control rates were low in younger age groups and males.
