Understanding Blood Pressure in Children: A Comprehensive Guide
Blood pressure is a vital health metric that’s not just important for adults but crucial for children as well. Contrary to common belief, hypertension (high blood pressure) isn’t exclusive to adults. The American Academy of Pediatrics (AAP) reports that approximately 3.5% of children and teenagers have high blood pressure, a condition that can lead to severe complications if left untreated.
Dr. Alan Sing, a pediatric cardiologist at Pediatric Heart Specialists, explains, “A blood pressure reading measures the force of blood against the walls of arteries. This pressure is what your heart has to pump against to get blood out to the rest of your body. If blood pressure is higher, then the heart has to work harder. Over time, this high blood pressure can cause damage to different organ systems in the body.”
The Importance of Regular Blood Pressure Screenings for Children
Regular blood pressure screenings are essential in identifying hypertension in children early on. These screenings should begin at age 3 and continue annually as part of a child’s routine check-up. For children with risk factors such as obesity or kidney disease, more frequent checks may be necessary.
How is Blood Pressure Measured in Children?
The process of measuring a child’s blood pressure is similar to that for adults. It involves the use of a stethoscope and a hand-inflated arm cuff. The child should be seated comfortably with their feet supported and arm at heart level. It’s important to note that a single high reading doesn’t necessarily indicate hypertension. Pediatricians track trends over time to make an accurate diagnosis.
Decoding Blood Pressure Numbers: What’s Normal for Kids?
Unlike adults, there isn’t a single set of numbers that defines normal blood pressure for all children. The healthy range depends on the child’s age, height, and gender. For children under 13, pediatricians use percentile charts to compare a child’s blood pressure to peers of the same age, height, and gender.
- Elevated blood pressure: Above the 90th percentile
- Hypertension: Above the 95th percentile
For teenagers 13 and older, the blood pressure ranges are the same as adults:
- Normal blood pressure: Less than 120/80 mm Hg
- Elevated blood pressure: Systolic between 120-129 mm Hg and diastolic less than 80 mm Hg
- Hypertension: Higher than 130/80 mm Hg
Identifying High Blood Pressure in Children: Signs and Symptoms
Hypertension in children often goes unnoticed as it’s typically a silent condition. This underscores the importance of regular screenings. However, some children may experience symptoms such as:
- Frequent headaches
- Changes in vision
- Dizziness
If your child complains of these symptoms persistently, it’s crucial to consult your pediatrician promptly.
Causes of High Blood Pressure in Children: Understanding the Risk Factors
High blood pressure in children can stem from various factors. These can be broadly categorized into two types: primary hypertension and secondary hypertension.
Primary Hypertension
Primary hypertension, more common in older children, has no specific disease-related cause. Risk factors include:
- Obesity or being overweight
- High-sodium diet
- Genetic predisposition
- Stress
Secondary Hypertension
Secondary hypertension, often seen in younger children (under 6), is caused by an underlying medical condition such as:
- Kidney disease
- Congenital or acquired heart disease
- Thyroid or adrenal disease
- Diabetes
Advanced Blood Pressure Monitoring in Children
In cases where a child consistently shows high blood pressure readings, pediatricians may recommend more advanced monitoring techniques. One such method is the use of a 24-hour, portable blood pressure monitoring device, also known as an ambulatory blood pressure monitor (ABPM).
How Does an ABPM Work?
An ABPM is a small device that the child wears for 24 hours, even during sleep. It takes blood pressure measurements at regular intervals:
- Every 20 to 30 minutes during daytime
- Every 30 to 60 minutes at night
This comprehensive monitoring provides a complete picture of the child’s blood pressure fluctuations throughout the day and night, helping pediatricians make more informed decisions about further tests or treatments.
Preventing and Managing High Blood Pressure in Children
While some risk factors for high blood pressure in children are beyond control (such as genetic predisposition), many are lifestyle-related and can be managed effectively. Here are some strategies to help prevent and manage hypertension in children:
Maintain a Healthy Weight
Obesity is a significant risk factor for hypertension in children. Encouraging a balanced diet and regular physical activity can help maintain a healthy weight.
Limit Sodium Intake
A high-sodium diet can contribute to elevated blood pressure. Reducing processed foods and adding less salt to meals can make a significant difference.
Promote Regular Physical Activity
Regular exercise not only helps maintain a healthy weight but also strengthens the heart and improves overall cardiovascular health. Aim for at least 60 minutes of moderate to vigorous physical activity daily.
Manage Stress
Stress can contribute to elevated blood pressure. Teach children stress management techniques such as deep breathing, mindfulness, or engaging in hobbies they enjoy.
Regular Check-ups
Ensure your child attends their annual check-ups where blood pressure is routinely measured. Early detection is key to preventing complications.
The Long-term Impact of Childhood Hypertension
Untreated high blood pressure in children can lead to serious health complications in adulthood. These may include:
- Heart disease
- Kidney failure
- Stroke
- Vision loss
By addressing hypertension early, we can significantly reduce the risk of these long-term health issues. This underscores the importance of regular monitoring and lifestyle interventions from an early age.
The Role of Diet in Managing Childhood Hypertension
Diet plays a crucial role in managing blood pressure, even in children. The DASH (Dietary Approaches to Stop Hypertension) diet, originally designed for adults, can be adapted for children with some modifications.
Key Components of a Blood Pressure-Friendly Diet for Kids
- Fruits and vegetables: Aim for a variety of colors to ensure a wide range of nutrients.
- Whole grains: Choose whole wheat bread, brown rice, and whole grain pasta over refined alternatives.
- Lean proteins: Include fish, poultry, and legumes in the diet.
- Low-fat dairy: Opt for low-fat milk and yogurt to reduce saturated fat intake.
- Limit added sugars: Reduce consumption of sugary drinks and snacks.
Remember, any dietary changes should be discussed with a pediatrician or a registered dietitian to ensure they meet the child’s nutritional needs.
The Impact of Sleep on Blood Pressure in Children
Recent studies have shown a correlation between sleep quality and blood pressure in children. Poor sleep habits or sleep disorders can contribute to elevated blood pressure.
How Much Sleep Do Children Need?
The American Academy of Sleep Medicine recommends the following sleep durations for optimal health:
- Children 3-5 years old: 10-13 hours per 24 hours (including naps)
- Children 6-12 years old: 9-12 hours per 24 hours
- Teenagers 13-18 years old: 8-10 hours per 24 hours
Establishing good sleep hygiene habits early can contribute to better blood pressure control and overall health.
The Role of Genetics in Childhood Hypertension
While lifestyle factors play a significant role in blood pressure, genetics also contribute to a child’s risk of developing hypertension. Children with a family history of high blood pressure are at an increased risk.
Can Genetic Risk Be Mitigated?
While we can’t change our genes, knowing about genetic risk can help in taking proactive measures. Children with a family history of hypertension should be monitored more closely, and lifestyle interventions should be implemented early to mitigate risk.
Medications for Childhood Hypertension: When Are They Necessary?
In most cases, lifestyle modifications are the first line of treatment for high blood pressure in children. However, in some instances, medication may be necessary.
Types of Blood Pressure Medications for Children
When medication is required, the most commonly prescribed types include:
- ACE inhibitors
- Angiotensin receptor blockers (ARBs)
- Beta-blockers
- Calcium channel blockers
- Diuretics
The choice of medication depends on various factors, including the child’s age, the severity of hypertension, and any underlying conditions. It’s crucial to note that medication should always be prescribed and monitored by a pediatric specialist.
The Psychological Impact of Hypertension Diagnosis in Children
Being diagnosed with a chronic condition like hypertension can have psychological effects on children. They may feel different from their peers or worry about their health.
Supporting Children with Hypertension
Parents and caregivers can support children with hypertension by:
- Educating them about the condition in age-appropriate terms
- Involving them in their care plan
- Encouraging open communication about their feelings
- Ensuring they feel supported and not blamed for their condition
In some cases, counseling or support groups may be beneficial to help children cope with their diagnosis.
The Future of Childhood Hypertension Management
As our understanding of childhood hypertension grows, so do the strategies for managing it. Emerging areas of research include:
Personalized Medicine
Advances in genetic testing may allow for more personalized treatment plans based on a child’s genetic profile.
Digital Health Tools
Apps and wearable devices are being developed to help children and families monitor blood pressure and implement lifestyle changes more effectively.
Novel Therapies
Research is ongoing into new medications and interventions that may provide better blood pressure control with fewer side effects.
As we continue to learn more about childhood hypertension, early detection and intervention remain key. Regular check-ups, a healthy lifestyle, and open communication with healthcare providers are the best ways to ensure optimal blood pressure control and overall health for children.
High Blood Pressure in Kids – Children’s Health
Share:
You may think that hypertension, or high blood pressure, is a condition that affects only adults. However, according to the American Academy of Pediatrics (AAP), an estimated 3.5% of children and teens have high blood pressure. When left untreated, this condition can cause serious complications, such as heart disease, kidney failure, stroke and vision loss.
“A blood pressure reading measures the force of blood against the walls of arteries. This pressure is what your heart has to pump against to get blood out to the rest of your body,” explains Alan Sing, M.D., a pediatric cardiologist at Pediatric Heart Specialists, a Children’s Health℠ Care Network Partner. “If blood pressure is higher, then the heart has to work harder. Over time, this high blood pressure can cause damage to different organ systems in the body.”
However, regular screenings can help identify high blood pressure in children. Learn more about what is considered high blood pressure for a child and ways you can help keep your child healthy.
How is a child’s blood pressure checked?
A child’s blood pressure should be checked once a year at their annual exam starting at the age of 3. Your child should sit comfortably in a chair with their feet supported and their arm level with their heart. Your child’s physician or nurse will use a stethoscope and a hand-inflated arm cuff to check their blood pressure.
If a child has a health condition that increases their risk for high blood pressure, such as obesity or kidney disease, their blood pressure will be checked at every doctor visit. If a child’s blood pressure is high at a well-child visit, their blood pressure will also be checked more frequently.
Your child’s pediatrician will track trends in blood pressure over time, not just the initial screening, to accurately identify a diagnosis of hypertension.
What is a normal blood pressure for a child?
There isn’t one single number or blood pressure that is considered normal for all children. A healthy blood pressure for a child depends on their age, height and gender.
For children under the age of 13, your pediatrician will use a percentile chart to compare your child’s blood pressure to peers of the same age, height and gender. This allows a more precise indication if a young child is showing high blood pressure. A child is considered to have an elevated blood pressure if their blood pressure falls above the 90th percentile, and hypertension if they are above the 95th percentile.
Over the age of 13, normal blood pressure ranges are the same for teenagers as they are for adults:
- Normal blood pressure: Less than 120/80 mm Hg
- Elevated blood pressure: Systolic (top number) between 120-129 mm Hg and diastolic (bottom number) less than 80 mm Hg
- Hypertension: Top or bottom number higher than 130/80 mm Hg
If your child’s pediatrician notices a trend of high blood pressure readings, they will closely monitor your child’s blood pressure or refer you to a specialist to address any health concerns. They may have your child wear a 24-hour, portable blood pressure monitoring device (called an ambulatory blood pressure monitor or ABPM). This can be worn at home during your child’s normal routine and takes measurements every 20 to 30 minutes during the daytime and 30 to 60 minutes at night.
This monitor can help your child’s pediatrician decide whether your child needs further tests or treatment by giving a complete picture of blood pressure throughout the day and night.
What are signs of high blood pressure in kids?
Hypertension is often a silent condition. Typically, there aren’t obvious symptoms to let parents know their child has high blood pressure; it is often diagnosed when the doctor discovers it during an exam. This is why regular blood pressure screening is so important.
Some children with high blood pressure may experience frequent headaches, changes in vision or dizziness. If your child complains of these symptoms, contact your pediatrician.
What are causes of high blood pressure in kids?
A child’s blood pressure might be high when it is measured for many reasons, such as stress, illness, recent physical activity, a true hypertension issue or a medical condition.
Causes of high blood pressure in kids can include:
- Obesity or being overweight
- High-sodium diet (too much salt)
- Kidney disease
- Congenital or acquired heart disease
- Thyroid or adrenal disease
- Diabetes
- Genetic disorders (inherited from a parent or grandparent)
- Stress
When a young child (under 6) has high blood pressure, the cause is often a related medical condition, such as kidney disease. This is called secondary hypertension.
When high blood pressure has no disease-related cause, it’s called primary hypertension. Primary hypertension is more common in older children and teens and is commonly related to obesity or to a family history of hypertension.
“There is a growing trend in the number of children and teens who are overweight or have obesity, and this is a major cause of high blood pressure in kids,” says Smitha Vidi, M.D., a pediatric nephrologist at Children’s Health and Assistant Professor at UT Southwestern. “Additionally, kids are eating a lot of processed foods, which have very high amounts of salt. A high-salt diet is a big contributor to increasing blood pressures.”
How is high blood pressure treated in children?
If your child is diagnosed with hypertension, your pediatrician may recommend certain lifestyle changes to lower their blood pressure, such as a healthy diet, regular exercise or weight loss.
- DASH diet: Designed from research sponsored by the National Institutes of Health, the DASH diet focuses on eating fruits, vegetables, low-fat dairy, nuts, beans and seeds.
- Exercise: The AAP recommends children and adolescents get 60 minutes or more of physical activity daily (includes outside play and team sports).
- Low-sodium diet: Sodium is the scientific name for the salt in food. In addition to watching table salt usage, be cautious of how much processed food your child eats.
If needed, your child’s physician may prescribe medications to control blood pressure. These medicines are the same ones adults take, just in age and weight-appropriate doses. Your child’s physician can choose the best medication for your child based on their individual health profile and risk factors.
You can help your child prevent high blood pressure and complications. Talk about the importance of a healthy lifestyle and continue to be a good role model – making healthy food choices and engaging in exercise as a family.
“Taking steps as a family to stay healthy is key to preventing hypertension in children,” says Dr. Vidi. “Try to devote a little of your time each day to doing fun activities with your kids, such as biking, dancing, swimming or even walking to a nearby park. “

The results of the 2012 to 2015Note 1 Canadian Health Measures Survey (CHMS) indicate that the average resting blood pressure of children and youth aged 6 to 19 was 97/62 mmHg. Among this group, 93% had a measured blood pressure that was considered normal and 7% had results considered borderline or elevated (data not shown).
In children aged 6 to 11, average resting blood pressure was 94/62 mmHg, while youth aged 12 to 19 had an average resting blood pressure of 99/63 mmHg.
The proportion of girls aged 12 to 19 with blood pressure in the normal range was significantly higher than that of girls aged 6 to 11 (Chart 1).

Blood pressure and body composition
Height and weight were measured for all CHMS respondents. Children and youth who were classified as being overweight (99/62 mmHg) or obese (102/64 mmHg) had a significantly higher average blood pressure than normal weight children (95/61 mmHg). Average systolic blood pressure was significantly higher in overweight and obese children compared with those in the normal weight category (Chart 2). As well, overweight and obese children had significantly higher average diastolic blood pressure when compared with their normal weight counterparts (Chart 3).Note 2Note 3Note 4Note 5

About blood pressure
Blood pressure is a measure of the force of blood against the artery walls, and is expressed as systolic pressure/diastolic pressure in millimetres of mercury (e. g., 120/80 mmHg). The systolic pressure (top number) is the pressure when the heart contracts and pushes the blood out, and the diastolic pressure (bottom number) is the lowest pressure when the heart relaxes between beats.
Resting blood pressure was measured in the CHMS using an automated device (BPTru™) following a five-minute rest period. The BPTru™ recorded six measurements, one minute apart. The average systolic and diastolic blood pressure were calculated using the last five out of six measurements.
The criteria for blood pressure classification in children and adults are as follows:
Category | Description | |
---|---|---|
Ages 6 to 17Note 2 | Ages 18 and 19Note 3 | |
Normal | SBP and DBP < 90th percentile | Mean SBP/DBP < 120/80 mmHg |
Borderline | SBP or DBP ≥ to the 90th percentile, but < the 95th percentile OR Measured mean SBP/DBP > 120/80 mmHg | Mean SBP of 120-139 mmHg and mean DBP of 80-89 mmHg OR Mean SBP of 120-139 mmHg and mean DBP Mean SBP |
Elevated | SBP or DBP ≥ 95th percentile OR Respondent reported using blood pressure medication within the past month | Mean SBP/DBP of ≥ 140/90 mmHg OR Respondent reported using blood pressure medication within the past month |

What should be the blood pressure of a child? Children’s cardiologist of the State Children’s Clinical Hospital Elena Malancheva answers the questions
Implementation of the regional project
“Fight against cardiovascular diseases” continues in the republic. In the City Children’s Clinical Hospital, every year diseases of the circulatory system are detected for the first time in about 0. 1-0.3% of children. Currently, more than 850 minor patients from 0 to 17 years old are under dispensary observation, which is 0.7% of the total attached population. Most often, children are diagnosed with heart and vascular defects, heart rhythm disturbances, high or low blood pressure.
Unfortunately, high (hypertension) or low blood pressure (hypotension) also occurs in children, although not as often as in adults. As a rule, the disease is asymptomatic and is detected either by chance, during a routine examination, or when complaints appear. The pediatric cardiologist of the City Children’s Clinical Hospital Elena Malancheva will tell you in detail about this.
- What is the age norm for blood pressure in children?
First of all, it should be noted that the upper pressure indicator, called systolic, is the pressure that occurs during the contraction phase of the heart muscle (systole). Lower, or diastolic, is the pressure that occurs during the relaxation phase of the heart muscle (diastole).
Systolic (upper) and diastolic (lower) pressure have their own minimum and maximum normal (physiological) values. They are measured in millimeters of mercury (mm Hg).
Below is a table with indicators of normal blood pressure (BP) in children in different age periods.
Age | Systolic (upper) indicator | Diastolic (lower) indicator | |||
Maximum value | Maximum value | Maximum value | Maximum value | ||
Newborns | From 60 | Up to 96 | From 40 | Up to 50 | |
2 months-year | From 80 | Up to 112 | From 50 | Up to 74 | |
1-2 years | From 82 | To 115 | From 61 | Up to 75 | |
2-3 years | From 85 | Up to 116 | From 60 | Up to 76 | |
3-4 years | From 90 | Up to 118 | From 60 | Up to 78 | |
4-5 years old | From 95 | Up to 120 | From 60 | Up to 80 | |
5-6 years old | From 100 | Up to 122 | From 60 | Up to 80 | |
6-8 years | From 110 | Up to 122 | From 70 | Up to 82 | |
8-11 years old | From 110 | Up to 126 | From 70 | To 82 | |
12-15 years old | From 110 | Up to 136 | From 70 | Up to 86 | |
15-16 years old | From 110 | Up to 136 | From 70 | Up to 90 | |
16-18 years old | From 110 | Up to 120 | From 80 | Up to 90 |
- What can be a reason to visit a doctor with a child ?
Blood pressure can vary depending on various factors. For example, in the morning, its indicators may be closer to the minimum normal limits, and increase during the day depending on the level of physical activity, the presence of stress factors, overwork, etc. If the numbers are within the physiological limits, then everything is in order, but if not, this is a reason to consult a doctor.
However, BP readings may be erroneous if the size of the rubber cuff does not match the size of the patient’s arm. For example, if a child uses an adult cuff, then the results are much lower.
- What can cause abnormal blood pressure in children?
If we talk about lowering blood pressure, then it can be observed during or after colds, with physical and mental overload, living in highlands (meaning adaptation to the environment), vegetative vascular disorders.
The causes of high blood pressure in a child are much more numerous. There are whole groups of diseases in which arterial hypertension occurs. These are some pathologies of the cardiovascular, endocrine, nervous system, kidneys and adrenal glands.
The most common causes of hypertension in children are obesity, hormonal dysfunction during adolescence, and autonomic vascular disorders.
Important! Parents should not forget that from about the age of 7, changes begin in a child’s life that can negatively affect blood pressure and health in general. Pressure at this age varies due to reduced physical activity, with the start of school and with a change in social circle, which is stressful.
Symptoms of elevated blood pressure: frequent headaches that are not relieved by classical anesthetics; headache worse on waking and after increased activity; discomfort in the region of the heart; lethargy, fatigue, the child is not too active even after a good rest; frequent nosebleeds; deteriorating vision; rapid heart rate.
Symptoms of low blood pressure: loss of strength, passivity, loss of interest not only in studies but also in play. The child often talks about a headache that is concentrated in the temple area, complains of nausea and loss of strength.
One of the important symptoms of low blood pressure is the lack of desire to eat. Later the fainting starts. Consciousness after fainting, as a rule, is restored without medical help, but sometimes urgent intervention is not enough.
Parents often confuse symptoms with overwork at school.
- What should parents do to prevent hypertension?
It is necessary to monitor the daily routine, including ensuring that the child has a good night’s rest. Regular, but moderate physical activity is important – it is enough to attend sports classes several times a week or do short morning exercises.
To strengthen the cardiovascular system, water procedures in warm water or under a contrast shower are relevant. Mandatory walks in the fresh air – at least two hours daily.
Parents need to control the amount of food consumed by the child – excess weight is one of the factors of high blood pressure. It is necessary to exclude harmful foods from the diet and control the amount of salt added to dishes.
It is also important to monitor the condition of the teeth – even incipient caries can cause changes in blood pressure.
I would also especially like to address parents of older children and teenagers. I strongly recommend limiting TV and phone viewing, especially 2 hours before bedtime; reduce headphone usage time. In addition, categorically exclude the use of energy drinks.
- Which doctor should I contact if my child’s blood pressure changes?
First of all, you should consult a pediatrician. Already at this stage, he can prescribe a detailed study, according to the results of which, if necessary, he will refer to narrow specialists: a cardiologist, neurologist, nephrologist, endocrinologist.
Be healthy!

Every mother should know what is the norm of blood pressure BE%D0%B5_%D0%B4%D0%B0%D0%B2%D0%BB%D0%B5%D0%BD%D0%B8%D0%B5) in children of a certain age, and, in fact, be able to notice in time changes. To begin with, it is worth noting that blood pressure in children, compared to adults, is lower – at an early age, the walls of the vessels are very thin, with a wide lumen. The capillary network is larger than in an adult and the blood pressure is correspondingly lower. But with age, the situation changes.
In this article you will learn:
- Causes of high blood pressure in children
- What are the norms of blood pressure in children?
- Rules for measuring blood pressure
Causes of high blood pressure in children
Normal blood pressure in children is an issue that worries many parents. It is important to remember that the factor that contributes to high blood pressure (among others) is excess. Elevated blood pressure can also occur as a result of physiological factors and manifest itself after strong emotional upheavals or physical exertion. On the other hand, low blood pressure is most often caused by pathological conditions such as thyroid dysfunction, diabetes mellitus or infectious diseases.
If you notice that your child’s blood pressure sometimes fluctuates, do not panic ahead of time. After all, pressure surges can be influenced by factors such as:
- Stress;
- Change of weather;
- Lack of physical activity or vice versa too intense physical activity;
- It is noteworthy that the pressure in girls, aged 5 to 10 years, is higher than in boys, then vice versa.
But if deviations from the norm occur frequently, and in addition to this, the child feels worse and has a headache, this is a clear reason for a visit to the doctor. In order to prevent the development of serious pathologies, it is necessary to notice the presence of pressure problems in the child in time and act as quickly as possible. What is the normal blood pressure in children? It is different for every age. In general, “normal” pressure is a general indicator of 3 values - SBP (systolic or upper), DBP (diastolic, the so-called lower) pressure and pulse. The difference between SBP and DBP is pulse pressure.
What are the norms of blood pressure in children?
In newborns, they are in the range of 60-96 and 40-50 units;
The older the child gets, the higher the rate. But the table shows averages for certain ages. How to understand what should be the pressure in children at 5 years old? Or what pressure of a 7-year-old child should not cause concern to parents? You can determine the norm of blood pressure for a specific age using the formula – we add 90 units to the number of years of the child to determine SBP, and 60 for DBP. A special device is used to measure pressure – a tonometer. Tonometers are mechanical or electronic.
Rules for measuring blood pressure
To get the most accurate result, you should follow certain rules:
- The measurement is carried out at rest, best after waking up;
- Hands should be on a hard surface with palms up;
- The cuff of the tonometer is attached to the arm in such a way that a finger can be inserted between it;
- Inflate and deflate the device slowly;
- For a more accurate result, it is recommended to take 2-3 measurements and choose the smallest value;
- If the child often has a headache and you need to get the results for further examination, measure the pressure for several days in a row, but strictly at a certain time – this way you will get the most accurate readings.
And, of course, you should not immediately diagnose some disease in your child.
