An HSE expert in obesity has said poor diets and lack of physical activity are likely to blame for a significant increase in high blood pressure among children. 

A study published in the Lancet Child and Adolescent Health journal revealed that the percentage of children with high blood pressure stood at 6.2% in 2020 - double the rate in 2000. 

High blood pressure is a major risk factor for stroke and heart attack, as it can damage blood vessels in the body.

The figure was double that recorded in 2000 and Professor Donal O’Shea described it as a “shocking” phenomenon. 

“The obesity levels over the last 20 years have not doubled - they have increased,” he explained to Newstalk Breakfast. 

 “But the levels of hypertension have doubled, the levels of pre-hypertension have doubled. 

“So, you nearly have 19% of kids under the age of 18 with abnormal blood pressure.” 

Professor O’Shea continued that the factors behind high levels of blood pressure are complex and multifaceted. 

“But what this is saying is it’s not just weight,” he added. 

“I think this is telling us it’s about physical activity and it’s about what’s in our diet. 

“So, I think the high fat, high salt, ulta-processed foods are contributing more to the blood pressure than weight. 

“I think physical inactivity and sedentary lifestyles that have been engineered into our day to day living is contributing. 

“We know if you go for a walk, if you’re active, your blood pressure is better in the hours and days after.”

The HSE advises anyone with high blood pressure to reduce their intake of salt, alcohol and caffeine. 

They should also sleep at least six hours a day, exercise regularly and eat a balanced, healthy diet.
