Abstract Background The Korean Society of Hypertension has published the Korea Hypertension Fact Sheet 2020 to provide an overview of the magnitude and management status of hypertension and their recent trends. Methods The Fact Sheets were based on the analyses of Korean adults aged 20 years or older of the 2007–2018 Korea National Health and Nutrition Examination Survey (KNHANES) and the 2002–2018 National Health Insurance Big Data (NHI-BD). Results Currently, the population average of systolic/diastolic blood pressure was 118/76 mmHg in Korean adults aged 20 years or older showing little change in the recent decade. However, the number of people with hypertension increased steadily, exceeding 12.0 million. Indeed, the number of people diagnosed with hypertension increased from 3.0 million in 2002 to 9.7 million in 2018. During the same period, the number of people using antihypertensive medication increased from 2.5 million to 9.0 million, and the number of people adherent to treatment increased from 0.6 million to 6.5 million. Hypertension awareness, treatment, and control rates increased rapidly until 2007, but showed plateaued thereafter. In 2018, the awareness, treatment, and control rates of hypertension among all adults were 67, 63, and 47%, respectively. However, the awareness and treatment rates were only 17 and 14% among adults aged 20 to 39 years old with hypertension. Among patients treated for hypertension, 61% of them were also using glucose-lowering or lipid-lowering drugs. Among antihypertensive prescriptions, 41% of the patients received monotherapy, 43% received dual therapy, and 16% received triple or more therapy. The most commonly prescribed antihypertensive medication was angiotensin receptor blockers, followed by calcium channel blockers and diuretics. Conclusion To achieve further improvement in management of hypertension, we need to encourage awareness and treatment in young adults. It is required to develop tailored prevention and management strategies that are appropriate for and inclusive of various demographics.
