Roundup: Cases of High Blood Pressure in Kids, Teens have Surged Globally; and More News

Study: High Blood Pressure in Children Has Doubled Globally Over Past 2 Decades

A global study has found that the rate of high blood pressure in children and teenagers has nearly doubled in just two decades. This finding, published in The Lancet Child & Adolescent Health, signals a growing health issue that many parents may not be aware of, researchers state.

High blood pressure, also known as hypertension, is a condition where the force of blood against your artery walls is consistently too high. Over time, this can lead to serious health problems like heart and kidney disease.

The study, which analyzed data from over 443,000 children worldwide, found that the prevalence of hypertension in those under 19 years old jumped from about 3 percent in 2000 to over 6 percent by 2020. That means more than 114 million young people globally are now affected.

One of the biggest drivers of this increase appears to be obesity. The research showed that nearly one in five children with obesity also have high blood pressure. This is a rate eight times higher than in children at a healthy weight.

What is “Normal” Blood Pressure for Kids?

Normal blood pressure in children and teenagers varies by age, gender, and height, but it is generally lower than the well-known “120/80” benchmark used for adults. For kids, healthy blood pressure ranges change as they grow.

In general, children and teens are considered to have normal blood pressure if their readings are below the 90th percentile for their age, sex, and height. Your child’s doctor can use specific charts to determine if their blood pressure falls within a healthy range.

Other Key Findings by Researchers

The study also shed light on how difficult it can be to detect this condition. Researchers discovered several important points about diagnosis:

• Masked Hypertension: Over 9 percent of children have what is called "masked hypertension." This is high blood pressure that doesn't show up during a regular checkup at the doctor's office but is present at other times. It requires out-of-office testing, like a monitor worn at home, to be detected.

• Prehypertension: An additional 8 percent of young people have prehypertension. This is when blood pressure levels are higher than normal but not yet in the high blood pressure range. Think of it as an early warning sign that hypertension could develop if lifestyle changes aren't made.

These findings suggest that many cases of high blood pressure in children are being missed. Relying only on in-office readings can lead to underdiagnosis or misdiagnosis.

Researchers emphasize the need for better screening and early detection. As a parent or caregiver, you can play an active role. Encourage a healthy lifestyle for your family, focusing on a balanced diet and regular physical activity to help manage weight.

It's also important to talk to your child's doctor about their blood pressure and ask if more comprehensive screening is needed, especially if there are risk factors like obesity. Addressing this issue now is key to preventing serious health complications later in life, researchers emphasis.

Can Coffee Help Prevent Irregular Heart Rhythms? A New Study Suggests It Might

For years, people with Atrial fibrillation (AFib) have been advised to avoid caffeine, as it was thought to trigger abnormal heart rhythms. However, a new study challenges this belief, suggesting that coffee might actually reduce the risk of AFib recurrence.

AFib is a common heart condition affecting over 6 million U.S. adults. It is characterized by an irregular and often rapid heartbeat. This condition can lead to serious complications like blood clots, stroke, and heart failure.

The study, called the DECAF trial, was presented at the American Heart Association’s Scientific Sessions 2025 and published in the journal JAMA. Researchers followed 200 adults with AFib who had undergone cardioversion therapy—a treatment that restores a normal heart rhythm using medication or an electric shock. Participants were divided into two groups: one continued drinking at least one cup of coffee daily, while the other avoided all caffeine for six months.

The results were surprising. Participants who drank coffee were 39 percent less likely to experience a recurrence of AFib or a related condition called atrial flutter (a rapid but regular heartbeat) compared to those who avoided caffeine. Specifically, 47 percent of coffee drinkers had a recurrence, compared to 64% in the no-caffeine group. These findings suggest that moderate coffee consumption may not only be safe for people with AFib but could also offer protective benefits.

Gregory Marcus, M.D., senior author of the study and a professor of medicine at the University of California, San Francisco, explained in a news release: “Our study results suggest that caffeinated coffee may not be responsible for raising the risk of AFib and may even reduce it.” However, he also noted that the study focused on people who already drank coffee regularly, so the effects on those new to caffeine remain unknown.

It’s important to highlight that the study participants consumed about one cup of coffee per day. The findings may not apply to those who drink larger amounts of coffee or other caffeinated beverages like energy drinks. Additionally, while many participants benefited from coffee, some individuals may still find that caffeine worsens their AFib symptoms. Dr. Marcus emphasized that it’s reasonable for healthcare providers to let patients experiment with naturally caffeinated drinks like coffee or tea, as long as they monitor their symptoms closely.

The study was conducted across five healthcare centers in the United States, Australia, and Canada between 2021 and 2024. Participants’ coffee consumption was self-reported during phone interviews, and any AFib episodes were verified using medical-grade electrocardiograms.

Chronic Kidney Disease Surges to Become 9^th Leading Cause of Death Globally

A significant global increase in chronic kidney disease (CKD), now affecting an estimated 788 million people, has placed the condition as a top ten cause of death globally for the first time.

This analysis, conducted by researchers from NYU Langone Health, the University of Glasgow, and the Institute for Health Metrics and Evaluation, underscores the growing public health crisis posed by this illness.

The report’s findings, published in The Lancet, shows a dramatic rise from 378 million cases in 1990, driven by population growth and aging. In 2023, approximately 1.5 million deaths were directly attributed to CKD, a mortality increase of over 6% since 1993 when adjusted for demographic changes. These figures have prompted organizations like the World Health Organization to prioritize CKD in its global health agenda.

Chronic kidney disease is a progressive condition where the kidneys gradually lose their ability to filter waste and excess fluids from the blood. While early stages may present no symptoms, advanced cases can necessitate dialysis or a kidney transplant.

The study highlights that CKD is not only a direct cause of mortality but also a major risk factor for other serious health issues. It contributed to about 12 percent of global cardiovascular deaths and was the 12th leading cause of diminished quality of life due to disability in 2023. Key risk factors identified include high blood sugar, high blood pressure, and high body mass index (obesity).

A critical finding from the research is that most individuals with CKD are in the early stages. This presents a vital opportunity for intervention. According to the study's authors, early detection through simple urine testing, followed by timely treatment with modern medications and lifestyle adjustments, can significantly slow the disease's progression. These measures can help prevent the need for more invasive and costly treatments like dialysis.

Despite the availability of effective new therapies, experts note that CKD remains widely underdiagnosed and undertreated on a global scale. This is particularly true in lower-income regions where access to advanced care is limited. The study serves as a call to action for policymakers and health systems to increase screening efforts and ensure that effective treatments are accessible and affordable for all patients diagnosed with this growing health threat.
