What is the average systolic blood pressure in a 15-year-old?

• A. 105 mm Hg
• B. 115 mm Hg
• C. 119 mm Hg
• D. 125 mm Hg

Answer: (C)

Understanding normal blood pressure in teens relies on age, sex, and height percentiles. By age 15, the average systolic pressure is in the low-to-mid 100s, typically around 118–120 mm Hg for teens of average height. That makes 119 mm Hg the best reflection of the typical mean for a 15-year-old. Values like 105 mm Hg are generally below the expected average for this age, while 115 and 125 are within or above the range but not as representative of the average as 119. Remember that individual measurements vary and clinicians refer to percentile charts and repeated readings to assess blood pressure status.
