Risk prediction model for high blood pressure

High blood pressure is becoming more common in children. This increase is linked not only to childhood obesity, but also to early-life factors like being born too small, too early, or growing up in difficult social conditions.

This matters because children with high blood pressure are more likely to have it as adults, which can lead to heart and kidney disease. However, high blood pressure in children is often missed because it is harder to measure and interpret than in adults, and routine screening is not always done.

Rather than screening all children, a better approach may be to focus on those most at risk—but there are currently no simple tools to help doctors do this.

This study will develop and test a tool to help identify children who are likely to have high blood pressure by age five, using data from large studies in Canada and the UK. Finding these children early could help prevent serious health problems later in life.
