Over 1 Billion People Worldwide Have Hypertension
According to a large study, high blood pressure rates around the world have almost doubled over the past 40 years to more than 1.1 billion. While rates have declined in wealthy countries—perhaps due to education about healthier diets and lifestyle choices—developing countries, especially in African and south Asia, have seen a sharp increase in high blood pressure rates.
In the largest study of its kind, researchers working with the World Health Organization analyzed blood pressure statistics from every country between 1975 and 2015. Blood pressure information from almost 20 million people was included in the study and the results were recently published in the Lancet.
In 2015, the United States, Canada, and South Korea had the lowest rates of hypertension. More than half of the adults with high blood pressure in 2015 lived in Asia—about 226 million people in China and 200 million people in India. According to researchers, lower rates in wealthier countries it may be due, in part, to better health care, better health overall, and a diet higher in fruit and vegetables.
