In 2015, there were 1.13 billion
people living with high blood pressure worldwide, with the majority of them in
low and middle-income countries.
The findings come from a new study
published Tuesday in The Lancet, which found that the number of people affected
by high blood pressure has almost doubled over the past 40 years.
In most countries, men were found to
have higher blood pressure than women.
The study highlighted a stark
contrast between where people are most affected, with high-income countries
showing a sharp decline in blood pressure among their populations in recent
decades, while low- and middle-income countries have seen numbers spike --
particularly in South Asia and Africa.
"When you look at this globally,
blood pressure is a condition of poverty, not affluence," said Majit
Ezzati, professor of global environmental health at Imperial College London,
who led the analysis. "The relationship with national income is completely
inverse."
The difference was made more evident
by that fact that half of the world's adults with high blood pressure in 2015
were living in Asia.
The United States, Canada and South
Korea had the lowest rates in the world, while the UK had the lowest proportion
of people with raised blood pressure in Europe.
"In the high-income world ... (rates)
are coming down despite the aging and increasing population," Ezzati said.
"But in the population (in Asia), as the age goes up, the blood pressure
tends to be higher."
He adds that this is most likely
down to differences between these populations in terms of healthy food options
but also access to health services providing diagnosis and treatment.
The
global highs and lows
An estimated 226 million people in
China were found to have high blood pressure, along with 200 million in India.
The top five countries for high blood pressure among men were all in Central
and Eastern Europe: Croatia, Latvia, Lithuania, Hungary and Slovenia. For
women, the top five were all in Africa: Niger, Chad, Mali, Burkina Faso and
Somalia.
