Surge in High Blood Pressure Among Children and Teens

A significant rise in high blood pressure among children and teenagers worldwide has been reported, nearly doubling over the past two decades. This increase is attributed to a mix of poor diets, lack of physical activity, and rising obesity rates, according to a comprehensive review.

About 114 million children are now dealing with hypertension before even reaching adulthood, facing serious health risks such as cardiovascular and kidney diseases, along with other complications.

The prevalence of high blood pressure among those under 19 has jumped from 3.2% to 6.2% in just 20 years. These findings come from a meta-analysis of 96 studies with over 400,000 children across 21 nations, published in The Lancet Child and Adolescent Health journal.

Obesity has emerged as a major factor behind this concerning trend. Nearly 19% of obese children are affected by hypertension, compared to less than 3% of those with a healthy weight.

“The near doubling of childhood hypertension over the past 20 years should be alarming for healthcare professionals and parents alike,” noted Prof Igor Rudan from Edinburgh University’s Usher Institute.

The study also indicates that around 8.2% of children and teens have prehypertension, which means their blood pressure is elevated but not yet classified as hypertension. Prehypertension appears to be more common during the teenage years, with an alarming rate of 11.8% compared to about 7% in younger children.

Experts observed that blood pressure tends to rise sharply during early adolescence, peaking around age 14, especially in boys. This underlines the necessity for routine screening in these crucial years.

Children with prehypertension are more likely to develop full-blown hypertension, raising additional concerns.

Prof Steve Turner, president of the Royal College of Paediatrics and Child Health, expressed deep concern over this significant rise, largely linked to childhood obesity, a condition that can be prevented. “We’re seeing children not only present with high blood pressure but also with obesity-related issues like type 2 diabetes — which was previously rare in kids — as well as asthma and mental health challenges,” he indicated.

He warned that persistent hypertension could lead to early mortality due to damage to vital organs, emphasizing that healthy childhood habits lead to healthier adulthood. Without immediate action, he fears we are on a path to a public health crisis.

The analysis reveals a troubling trend: from 2000 to 2020, the rate of high blood pressure among children almost doubled. In 2000, hypertension affected 3.2% of children, but by 2020, this figure had risen to over 6.2%, affecting 114 million youths globally.

Dr. Peige Song from Zhejiang University School of Medicine pointed out that the increase is driven by lifestyle choices — particularly unhealthy eating, lower physical activity, and growing obesity rates.

“We must address hypertension in young populations as a major public health issue,” she said. Parents play a crucial role in preventing and managing high blood pressure through promoting healthy habits, such as balanced diets with plenty of fruits and vegetables while reducing salt and sugar intake. Encouraging physical activity and cutting down on screen time are also vital actions.

For families with a history of hypertension, regular blood pressure monitoring for children is strongly advised. Detecting elevated levels early, especially via home monitoring, can help lessen the risk of severe complications.

Prof Bryan Williams from the British Heart Foundation shared his concern over the rising rates. “High blood pressure during childhood often carries into adulthood, raising the risk of heart disease and stroke later on.”

On a hopeful note, he mentioned that obesity-related hypertension can sometimes be reversed, but he also highlighted the need for strong government actions to tackle obesity among children. “Expanding restrictions on the advertising of unhealthy foods and urging the food industry to work towards healthier options are essential steps,” he added.
