A 6-year-old with repeated BP measurements in the 95-99th percentile for SBP and 90-95th percentile for DBP. How is this BP classified?

A 6-year-old with repeated BP measurements in the 95-99th percentile for SBP and 90-95th percentile for DBP. How is this BP classified?

• A. Normotensive
• B. Stage 1 hypertensive
• C. Pre-hypertensive
• D. Stage 2 hypertensive

Answer: (B)

In children, blood pressure classification is based on percentiles that depend on age, sex, and height. Hypertension is defined when the systolic or diastolic blood pressure is at or above the 95th percentile on repeated readings. Within that range, stage 1 hypertension refers to pressures that fall between the 95th percentile and the 99th percentile, while stage 2 hypertension is at or above the 99th percentile. Here, the systolic blood pressure is in the 95th to 99th percentile range, which meets the threshold for stage 1 hypertension. The diastolic reading is in the 90th to 95th percentile, which does not itself define hypertension, but hypertension in children is diagnosed if either value crosses the 95th percentile on repeated measurements. Since these readings are persistent, the pattern aligns with stage 1 hypertension.
