A startling rise in childhood hypertension demands immediate attention!
A recent meta-analysis published in The Lancet Child & Adolescent Health journal reveals a shocking trend: the rate of children and adolescents with high blood pressure has almost doubled globally from 2000 to 2020. In 2000, around 3.2% of children suffered from hypertension, but by 2020, this number had skyrocketed to over 6.2% among those under 19, impacting a staggering 114 million young individuals worldwide.
Obesity is a major culprit, with nearly 19% of obese children and adolescents having hypertension compared to less than 3% of their healthy-weight peers. This alarming trend is a wake-up call for healthcare professionals and caregivers alike.
But here’s where it gets controversial: the study suggests that the way blood pressure is measured can significantly impact prevalence estimates. Traditional in-office readings may underestimate the true extent of the problem. When hypertension is confirmed by a healthcare provider over multiple visits, the prevalence is around 4.3%. However, including out-of-office assessments like home monitoring reveals a higher prevalence of sustained hypertension, at about 6.7%.
Masked hypertension, which often goes undetected during routine check-ups, affects 9.2% of children and adolescents globally. Meanwhile, white-coat hypertension, where blood pressure rises only in medical settings, is estimated at 5.2%, indicating potential misdiagnosis.
“Childhood hypertension is more prevalent than we thought, and traditional methods may not capture the full picture,” says Dr. Peige Song, a study author. “Early detection and improved access to prevention and treatment are crucial to protect children’s health as they grow.”
The study also highlights the heightened risk for obese children, who are nearly eight times more likely to develop high blood pressure. Obesity-related health issues, such as insulin resistance and blood vessel changes, contribute to this increased risk.
Furthermore, the analysis identifies prehypertension in an additional 8.2% of children and adolescents, with higher rates during adolescence. This stage often progresses to full hypertension, emphasizing the need for regular screening during these formative years.
The study acknowledges limitations, including data variability and limited information on specific hypertension types and out-of-office assessments. Practical challenges, such as access to advanced monitoring tools, may hinder the implementation of recommended diagnostic procedures.
In a linked comment, Rahul Chanchlani, who was not involved in the study, emphasizes the need for harmonized diagnostic criteria, expanded out-of-office monitoring, and context-sensitive surveillance. He also highlights the importance of educating healthcare providers, families, and policymakers to integrate childhood hypertension prevention into broader strategies, recognizing that cardiovascular risk begins in childhood.
