Normal blood pressure in children varies by age, sex, and height. Understanding these parameters is crucial for monitoring and maintaining cardiovascular health in kids. Blood pressure (BP) is measured in millimeters of mercury (mmHg) and consists of two numbers: systolic pressure (the top number) and diastolic pressure (the bottom number). For children, what's considered normal depends on their age, sex, and height percentile. Pediatric healthcare providers use growth charts and blood pressure percentiles to assess whether a child's blood pressure is within a healthy range.
Blood pressure in children tends to increase with age, and it can be influenced by factors such as genetics, diet, physical activity level, and overall health. The American Academy of Pediatrics (AAP) provides guidelines for normal blood pressure ranges in children. According to the AAP, normal blood pressure in children is typically below the 90th percentile for their age, sex, and height. Blood pressure that falls between the 90th and 95th percentiles is considered elevated, and readings above the 95th percentile may indicate hypertension.
Normal Blood Pressure Ranges for Children by Age
The following are general guidelines for normal blood pressure ranges in children by age:
| Age | Systolic BP (mmHg) | Diastolic BP (mmHg) |
|---|---|---|
| Newborn (0-1 month) | 50-70 | 30-50 |
| Infant (1-12 months) | 70-100 | 50-70 |
| Toddler (1-2 years) | 80-110 | 50-70 |
| Preschooler (3-5 years) | 80-115 | 50-75 |
| School-age (6-12 years) | 90-120 | 60-80 |
| Adolescent (13-19 years) | 100-130 | 70-85 |
Factors Influencing Blood Pressure in Children
Several factors can influence blood pressure in children, including:
- Genetics: Family history of high blood pressure can increase a child's risk.
- Diet: A diet high in sodium and low in potassium can contribute to high blood pressure.
- Physical activity: Regular physical activity can help maintain healthy blood pressure.
- Weight: Being overweight or obese can increase the risk of high blood pressure.
- Overall health: Certain medical conditions, such as kidney disease or sleep apnea, can affect blood pressure.

Monitoring and Maintaining Healthy Blood Pressure in Children
Parents and caregivers can play a significant role in monitoring and maintaining healthy blood pressure in children. This includes:
Encouraging a healthy diet rich in fruits, vegetables, and whole grains.
Promoting regular physical activity, such as playing outside or participating in sports.
Limiting screen time and ensuring adequate sleep.
Monitoring and managing stress levels.
Regular blood pressure checks during pediatric visits.
What is considered normal blood pressure for a 10-year-old child?
+For a 10-year-old child, normal blood pressure is typically below 120⁄80 mmHg. However, the exact range can vary depending on their height and sex.
How often should children’s blood pressure be checked?
+The American Academy of Pediatrics recommends that children’s blood pressure be checked annually during routine pediatric visits, starting at age 3.
Can diet affect blood pressure in children?
+Yes, diet can significantly affect blood pressure in children. A diet high in sodium and low in potassium can contribute to high blood pressure.
