What is categorized as 'Stage 2 HTN' for a pediatric patient under 13 years old?

For a pediatric patient under 13 years old, 'Stage 2 Hypertension' is defined as having blood pressure readings at or above the 95th percentile plus an additional margin of at least 12 mmHg. This classification considers both the child's age, sex, and height, as blood pressure norms vary significantly among different growth stages.

The definition recognizes that blood pressure readings at or above this threshold are indicative of more severe hypertension. This classification is crucial for determining appropriate management and intervention strategies to reduce cardiovascular risk and prevent long-term health complications.

Understanding the context of hypertension in children is important, as early detection and treatment can lead to better health outcomes. For example, merely identifying a child's blood pressure as being at the 95th percentile does not automatically indicate 'Stage 2.' It is essential to quantify how significantly it exceeds this percentile to classify it accurately, hence the addition of 12 mmHg to the 95th percentile designation.
