Hypertension Diagnosis, Treatment, and Control Worldwide

Headshot of Goodarz Danaei

CHDS affiliate Goodarz Danaei with colleagues at the Non-Communicable Disease Risk Factor Collaboration (NCDRisC) published a recent study in The Lancet that shows substantial differences in quality of care for hypertension across the world.

The study summarizes data from 1,201 population-based surveys with 104 million participants covering the years 1990 to 2019. The results indicated that the number of hypertensive patients has nearly doubled in the past three decades, but rates of diagnosis, treatment, and control remain suboptimal in almost all regions, with less than a quarter of all patients globally being optimally controlled. Many high-income and some middle-income countries (e.g., Costa Rica, Turkey, Iran) had substantial improvements in treatment and control over the time period. In contrast, the rates of control in many sub-Saharan African countries remained unchanged in the past thirty years.
