Normal blood pressure for school age child. Uncovering the Secrets of Normal Blood Pressure for School-Age Children: A Comprehensive Guide on High Blood Pressure in Kids
What is a normal blood pressure for a school-age child? How can high blood pressure in kids be detected and treated? Discover the answers to these questions and more in our in-depth article.
Measuring a Child’s Blood Pressure: The Importance of Regular Screenings
Contrary to popular belief, high blood pressure, or hypertension, is not just a condition that affects adults. According to the American Academy of Pediatrics (AAP), an estimated 3.5% of children and teenagers also struggle with this health concern. Regular blood pressure screenings starting at the age of 3 are crucial to identify and address high blood pressure in kids before it can lead to serious complications, such as heart disease, kidney failure, stroke, and vision loss.
During a typical blood pressure check, a child will sit comfortably in a chair with their feet supported and their arm level with their heart. The child’s physician or nurse will use a stethoscope and a hand-inflated arm cuff to measure the 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.
Understanding Normal Blood Pressure Ranges for Children
There is no single blood pressure number 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, pediatricians use a percentile chart to compare a child’s blood pressure to their peers of the same age, height, and gender. 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.
For teenagers aged 13 and older, normal blood pressure ranges are the same as those 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
Identifying the Signs and Causes of High Blood Pressure in Children
Hypertension in children is often a silent condition, meaning there are typically no obvious symptoms to alert parents that their child has high blood pressure. Regular blood pressure screenings are crucial to identify this health concern. Some children with high blood pressure may experience frequent headaches, changes in vision, or dizziness, but these symptoms are not always present.
The causes of high blood pressure in children can vary, including obesity, a high-sodium diet, kidney disease, congenital or acquired heart disease, thyroid or adrenal disease, diabetes, genetic disorders, and stress. When a young child (under 6) has high blood pressure, the cause is often a related medical condition, known as secondary hypertension. In older children, primary hypertension, which has no disease-related cause, is more common.
Monitoring and Managing High Blood Pressure in Children
If a child’s pediatrician notices a trend of high blood pressure readings, they will closely monitor the child’s blood pressure or refer them to a specialist to address any health concerns. The child may be asked to wear a 24-hour, portable blood pressure monitoring device (called an ambulatory blood pressure monitor or ABPM) to provide a complete picture of their blood pressure throughout the day and night.
Depending on the cause and severity of the high blood pressure, the child’s treatment plan may include lifestyle changes, such as a healthier diet and increased physical activity, or medication. It is crucial to work closely with the child’s healthcare team to develop an effective management strategy and ensure that the child’s blood pressure remains within a healthy range.
Preventing High Blood Pressure in Children: Promoting Healthy Habits
While some causes of high blood pressure in children are out of their control, such as genetic factors or underlying medical conditions, there are steps parents and caregivers can take to help prevent and manage this health concern. Encouraging a balanced diet low in sodium, promoting regular physical activity, and maintaining a healthy weight can all contribute to maintaining normal blood pressure in children.
By working closely with their child’s healthcare team and implementing healthy lifestyle habits, parents can play a crucial role in supporting their child’s overall cardiovascular health and well-being.
The Importance of Ongoing Monitoring and Collaboration with Healthcare Providers
Monitoring a child’s blood pressure is an ongoing process that requires a collaborative effort between parents and healthcare providers. Regular check-ups, screenings, and open communication with the child’s pediatrician or specialist are essential to ensuring that any issues are identified and addressed in a timely manner.
By staying vigilant and working closely with their healthcare team, parents can help ensure that their child maintains a healthy blood pressure and avoids the potential long-term consequences of untreated hypertension.
Conclusion
High blood pressure in children is a serious health concern that should not be overlooked. Regular blood pressure screenings, understanding normal ranges, and identifying the signs and causes of hypertension are crucial steps in keeping children healthy. By promoting healthy lifestyle habits and working closely with healthcare providers, parents can play a vital role in preventing and managing high blood pressure in their 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.
