Hypertension affects 1 in 3 adults worldwide: WHO

The global health body  World Health Organization (WHO) in a recently released report has highlighted that hypertension affects 1 in 3 adults worldwide. This common, deadly condition leads to stroke, heart attack, heart failure, kidney damage and many other health problems. 

The report has revealed that 4 out of every 5 people with hypertension are not adequately treated, but if countries can scale up coverage, 76 million deaths could be averted between 2023 and 2050. 

The WHO has released its first-ever report on the devastating global impact of high blood pressure, along with recommendations on the ways to win the race against this silent killer. 

The number of people living with hypertension (blood pressure of 140/90 mmHg or higher or taking medication for hypertension) doubled between 1990 and 2019, from 650 million to 1.3 billion. Nearly half of people with hypertension globally are currently unaware of their condition. More than three-quarters of adults with hypertension live in low- and middle-income countries.

Older age and genetics can increase the risk of having high blood pressure, but modifiable risk factors such as eating high-salt diet, not being physically active and drinking too much alcohol can also increase the risk of hypertension.

Lifestyle changes like eating a healthier diet, quitting tobacco and being more active can help lower blood pressure. Some people may need medicines that can control hypertension effectively and prevent related complications. 

The prevention, early detection and effective management of hypertension are among the most cost-effective interventions in health care and should be prioritized by countries as part of their national health benefit package offered at a primary care level. The economic benefits of improved hypertension treat­ment programmes outweigh the costs by about 18 to 1. 

“Hypertension can be controlled effectively with simple, low-cost medication regimens, and yet only about one in five people with hypertension have controlled it.” Said Dr. Tedros Adhanom Ghebreyesus, WHO Director-General. “Hypertension control programmes remain neglected, under-prioritized and vastly underfunded. Strengthening hypertension control must be part of every country’s journey towards universal health coverage, based on well-functioning, equitable and resilient health systems, built on a foundation of primary health care.”
