As children grow from preschool to high school, what trend is observed in blood pressure readings?

As children transition from preschool through high school, a clear trend in blood pressure readings is observed, where blood pressure tends to increase. This increase is a normal part of growth and development.

During early childhood, blood vessels are still developing, and as a child grows, their body undergoes various physiological changes that include increases in body size, muscle mass, and changes in metabolic rates. These factors contribute to the rise in blood pressure, reflecting the demand for increased blood flow to support growing tissues and organs. It is essential to monitor blood pressure periodically during childhood and adolescence, as this can provide critical insights into cardiovascular health and the development of potential risk factors later in life.

Constant blood pressure readings would not accurately reflect the natural development process, while fluctuations would suggest underlying issues or irregularities that are not typically observed in healthy growth patterns.
