Worldwide Blood Pressure Patients Doubled In Last 30 Years, Claims Lancet

Read Time:3 Minute, 6 Second

According to a recent study published in The Lancet journal, the number of people suffering from hypertension worldwide has doubled in the past 30 years, with the majority of patients found in low- and middle-income countries. In this study, an international team of researchers analyzed data from more than 1,200 national studies covering 184 countries in the world. In which they found that an estimated 331 million women and 317 million men were suffering from high blood pressure in 1990. Which figure has increased to 626 million women and 652 million men in 2019? That is, in 30 years, the case of high blood pressure patients has doubled.

Despite the disease being relatively easy to monitor and relatively easy to treat with low-cost drugs, nearly half of people with high blood pressure worldwide in 2019 were unaware of their condition, the researchers said. He said more than half of the women (53 percent) and men (62 percent) were not treated.

According to lead researcher Majid Ezzati of Imperial College London, ‘Despite medical and pharmacological advances over the decades, global progress in hypertension management has been slow, and the majority of people with high blood pressure in low- and middle-income countries avoid treatment due to major losses. remain deprived,

Ezzati added that ‘our analysis has revealed good practice in the diagnosis and treatment of hypertension not only in high-income countries but also in middle-income countries,’

Worldwide, more than 8.5 million deaths each year are linked to hypertension. And it is the major risk factor for stroke, ischemic heart disease, kidney disease. Lowering blood pressure can reduce the number of strokes by 35-40 percent, heart attacks by 20-25 percent, and heart failure by about 50 percent. High blood pressure was defined as a systolic blood pressure of 140 millimeters of mercury (mm Hg) or higher and diastolic blood pressure of 90 mm Hg or more or taking medication for high blood pressure.

what is diastolic pressure?

The amount of pressure in the arteries during the contraction of the heart muscle is called systolic pressure. The blood pressure when the heart muscle is held between beats is called diastolic pressure.

What do researchers have to say?

The global age-standard prevalence of high blood pressure among youth has remained largely unchanged over the past 30 years – with nearly a third of young people living with hypertension worldwide in 1990 and 2019, the researchers said. He noted that rates declined sharply in high-income countries, but increased or remained unchanged in many low- and middle-income countries (LMICs), particularly in Oceania. According to the study, Canada and Peru had the lowest proportion of people suffering from high blood pressure at 1 in 4 in 2019. While Taiwan, South Korea, Japan, and some countries in Western Europe, including Switzerland, Spain, and the UK, had the lowest rates of hypertension in women, Eritrea, Bangladesh, Ethiopia, and the Solomon Islands had the lowest rates for men.

The researchers said that treatment and control have improved in most countries since 1990, especially in high-income countries such as Canada, Iceland, and South Korea. However, there is little change in LMICs in sub-Saharan Africa and Oceania, Nepal, and Indonesia.

‘The ability of these countries to detect and treat hypertension as part of primary health care and universal health coverage should improve,’ said co-author Leanne Riley from WHO, Switzerland.

The authors note that while the study provides the first comparable estimates of the prevalence, diagnosis, treatment, and control of blood pressure among youth for all countries in the world, this may be hampered by the paucity of data in some countries, notably Oceania and the Sub-continent. – Saharan Africa.
