Baltimore, MD – Preliminary research unveiled sunday at the American Heart Association’s Hypertension Scientific Sessions 2025 suggests that elevated Blood Pressure in young children may considerably increase their risk of dying from cardiovascular disease decades later. The findings, simultaneously published in JAMA, highlight the critical need for regular blood pressure checks in childhood and the promotion of heart-healthy lifestyles from a young age.
The study, led by Alexa Freedman, Ph.D., of Northwestern University’s Feinberg School of Medicine, found that children with higher blood pressure readings at age seven faced a 40% to 50% greater risk of early death from cardiovascular issues over the following five decades. “We were surprised to find that high blood pressure in childhood was linked to serious health conditions many years later,” Dr. Freedman stated. “Our results highlight the importance of screening for blood pressure in childhood and focusing on strategies to promote optimal cardiovascular health beginning in childhood.”

previous studies have indicated a connection between childhood blood pressure and adult cardiovascular health. A 2022 study demonstrated that elevated blood pressure in older children (around age 12) correlated with an increased risk of cardiovascular death by middle age (around 46). However, this new research is the first to comprehensively examine the impact of both systolic and diastolic blood pressure levels in young children-specifically at age seven-on long-term cardiovascular mortality risk within a diverse population.
Current clinical guidelines from the American Academy of Pediatrics recommend annual blood pressure screenings for children starting at age three. Bonita Falkner, M.D., FAHA, an American Heart Association volunteer expert, emphasized the value of these screenings.”The results of this study support monitoring blood pressure as an critically important metric of cardiovascular health in childhood,” she said. “Moreover, the results of this study and other older child cohort studies with potential follow-up in adulthood will contribute to a more accurate definition of abnormal blood pressure and hypertension in childhood.”
Study Details and Findings
Researchers analyzed data from approximately 38,000 children who participated in the Collaborative Perinatal Project (CPP) between 1959 and 1965. They tracked participants’ survival and cause of death through 2016, utilizing the National Death Index. Blood pressure measurements taken at age seven were categorized based on age, sex, and height-specific percentiles, aligning with American Academy of Pediatrics guidelines. Demographic factors and childhood Body Mass Index (BMI) were also considered to ensure the findings were directly related to blood pressure and not influenced by weight status.
The analysis revealed the following key findings:
- Children with higher blood pressure at age seven were more likely to die from cardiovascular disease in their mid-50s. The highest risk was observed in those whose blood pressure fell within the top 10% for their age, sex, and height.
- By 2016,504 of the 2,837 deaths recorded among participants were attributed to cardiovascular disease.
- Both elevated blood pressure (90th-94th percentile) and hypertension (≥95th percentile) were associated with a 40% to 50% increased risk of early cardiovascular death.
- Even moderately elevated blood pressure-still within the normal range-increased the risk of premature cardiovascular death by 13% (for systolic) and 18% (for diastolic).
- Sibling analysis, involving 150 sibling pairs, showed similar risk increases for those with higher blood pressure at age seven, even when accounting for shared family and environmental factors.
“Even in childhood, blood pressure numbers are important because high blood pressure in children can have serious consequences throughout their lives,” Dr. Freedman cautioned. “It is indeed crucial to be aware of your child’s blood pressure readings.”
| Blood Pressure Category | risk Increase (vs. normal) |
|---|---|
| Elevated Blood Pressure (90-94th percentile) | 40-50% Higher Risk |
| Hypertension (≥95th percentile) | 40-50% Higher Risk |
| Moderate Elevation (Systolic) | 13% Higher Risk |
| Moderate Elevation (Diastolic) | 18% Higher Risk |
Did you know? The American Heart Association recommends that children begin regular cardiovascular screenings at age 3.
Pro Tip: Incorporating a diet rich in fruits and vegetables, regular physical activity, and limited processed foods can help maintain healthy blood pressure levels in children.
The study acknowledges certain limitations, including the reliance on a single blood pressure measurement taken at age seven and the predominantly Black and white participant base of the CPP. Researchers note that lifestyle factors and environmental exposures may differ for today’s children.
Understanding Childhood Hypertension
Childhood hypertension is increasingly prevalent,fueled by rising rates of obesity and sedentary lifestyles. While frequently enough asymptomatic, elevated blood pressure in children can lead to significant health problems later in life, including heart disease, stroke, and kidney failure. Early detection and intervention are crucial to prevent these long-term consequences. According to the CDC, approximately 1 in 13 children and adolescents has high blood pressure. CDC Resources
frequently Asked Questions About Childhood Blood Pressure
- What is considered high blood pressure for a child? High blood pressure in children is determined based on age, sex, and height percentiles, not fixed numbers as in adults.
- How often should my child’s blood pressure be checked? The American Academy of Pediatrics recommends annual blood pressure screenings starting at age three.
- What can I do to help my child maintain healthy blood pressure? Encourage a healthy diet, regular physical activity, and limit screen time.
- Is childhood hypertension always a sign of a serious problem? Not always, but it requires monitoring and potential intervention to prevent future complications.
- Are there any symptoms of high blood pressure in children? Most children with high blood pressure have no symptoms, making regular screenings vital.

What are the long-term cardiovascular consequences of childhood hypertension?
Childhood High Blood Pressure Linked to Earlier Heart Disease Death in Adulthood
Understanding the Connection: pediatric Hypertension & Long-Term Heart Health
Childhood high blood pressure (hypertension) is no longer considered simply a “pediatric” problem. Increasingly, research demonstrates a strong adn concerning link between elevated blood pressure in children and adolescents and an increased risk of heart disease and premature death in adulthood.This isn’t just about kids with obvious health issues; even mildly elevated blood pressure can have lasting consequences. Understanding this connection is crucial for preventative care and improving long-term cardiovascular outcomes. We’ll explore the latest findings on pediatric hypertension, its impact, and what can be done.
The Rising Prevalence of Childhood Hypertension
For decades, high blood pressure was thought to be rare in children.However, rates are climbing, mirroring the rise in childhood obesity and related lifestyle factors.
Statistics: Recent studies indicate that up to 5% of children and adolescents have high blood pressure. This number is considerably higher in certain populations, especially those with obesity, diabetes, or a family history of cardiovascular disease.
Contributing Factors: several factors contribute to this increase:
Obesity: Excess weight puts a strain on the heart and blood vessels.
poor Diet: High sodium intake and low potassium intake contribute to hypertension.
Lack of Physical Activity: Regular exercise helps maintain a healthy weight and blood pressure.
Stress: Chronic stress can elevate blood pressure.
Genetics: A family history of hypertension increases a child’s risk.
How Childhood Hypertension Impacts Adult Cardiovascular Health
The damage caused by elevated blood pressure in childhood isn’t instantly apparent. It’s a slow, insidious process that unfolds over decades.
Vascular Damage: High blood pressure damages the lining of blood vessels, leading to atherosclerosis (plaque buildup). This process begins in childhood and accelerates over time.
Left Ventricular Hypertrophy (LVH): The heart has to work harder to pump blood against increased resistance, causing the left ventricle (the heart’s main pumping chamber) to thicken. LVH is a strong predictor of future cardiovascular events.
Increased Risk of Adult Cardiovascular Diseases: Children with hypertension are at a significantly higher risk of developing:
Coronary Artery Disease (CAD)
Heart Failure
Stroke
Kidney Disease – often linked to hypertension.
Peripheral Artery Disease (PAD)
Identifying Childhood Hypertension: Screening & Diagnosis
Early detection is key. Regular blood pressure screenings are essential for all children, starting at age 3.
Blood Pressure Measurement: accurate measurement is crucial. Proper cuff size and technique are vital. Multiple readings should be taken and averaged.
Classification of Blood Pressure: Pediatric hypertension is classified into stages:
Normal: Below the 90th percentile for age, sex, and height.
Elevated: Between the 90th and 95th percentile.
Stage 1 Hypertension: Between the 95th and 99th percentile, or systolic blood pressure (SBP) 130-139 mmHg or diastolic blood pressure (DBP) 80-89 mmHg.
Stage 2 Hypertension: Greater than the 99th percentile, or SBP ≥ 140 mmHg or DBP ≥ 90 mmHg.
Secondary Hypertension: in certain specific cases, high blood pressure is caused by an underlying medical condition (e.g., kidney disease, hormonal disorders). This is known as secondary hypertension and requires specific treatment.
Lifestyle Interventions: The First Line of Defense
For many children with elevated blood pressure, lifestyle changes are the first and most effective approach.
Dietary Modifications:
Reduce Sodium Intake: Limit processed foods, fast food, and salty snacks.
Increase Potassium Intake: Encourage consumption of fruits, vegetables, and low-fat dairy products.
Adopt the DASH Diet: The Dietary Approaches to Stop Hypertension (DASH) diet is rich in fruits,vegetables,and low-fat dairy,and low in saturated and total fat.
Regular Physical Activity: Aim for at least 60 minutes of moderate-to-vigorous intensity exercise most days of the week.
Weight Management: Achieving and maintaining a healthy weight is crucial.
* Stress reduction: Teach children healthy coping mechanisms for stress, such as mindfulness, yoga, or spending time in nature.
Pharmacological Interventions: When Medication is Necessary
In some cases, lifestyle changes alone are not enough to control blood pressure. Medication might potentially be necessary, particularly for children with Stage 2 hypertension or secondary hypertension.
