Hypertension, the silent killer that is taking more strength in recent years ​

Worldwide trends in hypertension prevalence and progress in treatment and control from 1990 to 2019: a pooled analysis of 1201 population-representative studies with 104 million participants ​

A new study was recently published in the Lancet examined with data between 1990 to 2019 of people aged 30–79 years from population-representative studies with information on blood pressure measurement and blood pressure treatment. Hypertension was defined as having systolic​

blood pressure ≥ 140 and diastolic blood pressure ≥ 90 mm Hg, or taking medication for hypertension.​

This novel comprehensive analysis of hypertension prevalence and care has shown that since 1990 the number of people with hypertension worldwide has doubled, with most of the increase occurring in low-income and middle-income regions. ​

To our knowledge, no previous study of trends in hypertension prevalence, detection, treatment, and control coverered all countries in the world.​

​

• The number of people aged 30–79 years with hypertension doubled from 1990 to 2019, from 331 million women and 317 million men in 1990 to 626 million women and 652 million men in 2019.​

• Hypertension prevalence surpassed 50% for women in two countries and men in nine countries, in central and eastern Europe, central Asia, Oceania, and Latin America. Globally, 59 of women and 49% of men with hypertension reported a previous diagnosis of hypertension in 2019.​

• Control rates among people with hypertension in 2019 were 23% for women and 18% for men​

The dual approach of reducing hypertension prevalence through primary prevention and enhancing its treatment and control is achievable not only in high-income countries but also in low-income and middle-income settings.​
