Hypertension is the most common disease in elderly persons and a potent risk factor for cardiovascular disease. However, recent prevalence of persons with hypertension are not well described in Korean population.Design and Method:
This cross-sectional study was performed using the Korean NHIS sample cohort dataset, which was a semi-dynamic cohort included approximately 1 million individuals from South Korea and obtained between 2002 and 2013.Results:
In 2002, a total of 63286 persons with diagnosed hypertension were identified; 37.3% were aged 65 years or older. The prevalence of hypertension was 6.2%. Hypertension was more common in women than in men (5.2% vs 7.2%, P < 0.0001). In 2013, a total 146202 of persons with diagnosed hypertension were identified; 47.3% were aged 65 years or older. The prevalence of hypertension was 14.4%. The higher prevalence of hypertension in women maintained. (13.8% vs 15.0%, P < 0.0001). During 11 years, the prevalence of hypertension increased by 0.7% annually and mean age increased by 0.5 years annually. Tre prevalence of hypertension was significantly correlated with the mean age (r = 0.99, P < 0.0001).Conclusions:
Our study confirms that hypertension is common among older adults and the prevalence of hypertension increased rapidly with increase in mean age. Coordinated efforts are needed to face the increasing challenge of blood pressure management and complication prevention in patients with hypertension.
