What is the normal range of blood pressure in 12-year-old children?

The normal range of blood pressure in 12-year-old children is usually 90-120mmHg systolic blood pressure and 60-80mmHg diastolic blood pressure.

If the measured blood pressure value is higher or lower than this range, it is abnormal, indicating that the blood pressure is high or low. Because blood pressure is easily affected by factors such as environment, mood, exercise, eating, etc., it is necessary to exclude physiological factors for abnormal blood pressure in a short time. However, if the blood pressure value is abnormal for three consecutive days, hypertension or hypotension can be diagnosed and active treatment should be given.

Daily, children should be urged to develop healthy habits, such as early to bed, early to work, regular rest, balanced diet, etc., so as to improve their physical fitness.
