Hypertension Affects Twice as Many People as It Did in 1990
These findings are from an international study that looked at changes in the prevalence and treatment of hypertension in 184 countries between 1990 and 2019.
Even though it is relatively simple to identify and treat with inexpensive medications, high blood pressure is known as a “silent killer” by the medical community because most individuals have no symptoms.
According to research conducted by an international team of scientists, nearly 41% of women and 51% of men with hypertension, or 20% of adults total, weren’t aware of their illness in 2019.
The Non-Communicable Disease Risk Factor Collaboration (NCD-RisC) looked at data from 1,201 studies that represented 184 countries’ populations. Blood pressure measurements and treatment information for a total of 104 million participants were used.
According to the researchers’ calculations, the global population of adults aged 30–79 years with hypertension grew from over 650 million in 1990 to nearly 1.3 billion in 2019. And that progression took place in low- and middle-income countries.
Treatment and control have improved in high-income countries such as the United States, Germany, and Portugal. Iceland, Canada, and South Korea had the most significant advances.
However, certain middle-income nations, such as Costa Rica, South Africa, Kazakhstan, Turkey, Brazil, and Iran, have made significant progress in treating and controlling hypertension.
According to the study, in Nepal, Indonesia, and most nations in Sub-Saharan Africa and Oceania, however, there was minimal progress in the treatment and control of hypertension.
In 2019, less than a quarter of women and a fifth of men with high blood pressure in these nations received therapy. Only about 10% of the participants had well-controlled blood pressure.
According to the researchers, smoking and poor diets, both of which lead to obesity, are contributing factors.
The authors of the current study point out some of the study’s limitations. Some nations, particularly in Sub-Saharan Africa and Oceania, had fewer data available for study.
Furthermore, because the surveys did not consistently collect this information, the team could not compare the types of medicines used to treat high blood pressure in different nations.
