High blood pressure now a major problem in developing world
THE number of people in the world suffering from high blood pressure has almost doubled over the past four decades, with the biggest rise in south Asia and Africa.
“High blood pressure is the leading risk factor for stroke and heart disease, and kills around 7.5 million people worldwide every year,” said professor Majid Ezzati, lead author of the study.
“Taken globally, high blood pressure is no longer a problem of the Western world or wealthy countries. It is a problem of the world’s poorest countries and people.”
Between 1975 and 2015, the tally of adults with high blood pressure rose from 594 million to over 1.1 billion, according to the overview, published in The Lancet medical journal.
At the same time, high income countries such as Australia, Canada, Germany and Japan have made “impressive reductions” in the prevalence of high blood pressure.
The biggest increase in cases was registered in low- and middle-income countries in sub-Saharan Africa, South Asia and some Pacific island nations, researchers found.
In 2015, more than half of all adults with high blood pressure – some 590 million people – were living in east, southeast and south Asia. Of that number, 226 million were in China and 199 million in India.
Around one-third of woman living in most West African countries also suffer from high blood pressure.
Hypertension also remains a “serious health problem” in several countries in central and eastern Europe, where more than one-third of men are living with the condition.
People with high blood pressure have a higher risk of heart disease, stroke, kidney disease and dementia.
Canada, Australia, Britain, US, Peru, South Korea and Singapore had the lowest proportion of adults with high blood pressure, with fewer than one in eight women and one in five men affected. –
