Blood pressure matters at all ages. Children with higher blood pressure at age 7 may be at an increased risk of dying of cardiovascular disease by their mid-50s, according to preliminary research presented at the American Heart Association’s Hypertension Scientific Sessions 2025, held in Baltimore, September 4–7, 2025.

The study is simultaneously published in JAMA.

“We were surprised to find that high blood pressure in childhood was linked to serious health conditions many years later. Specifically, having hypertension or elevated blood pressure as a child may increase the risk of death by 40% to 50% over the next five decades of an individual’s life,” said Alexa Freedman, Ph.D., lead author of the study and an assistant professor in the department of preventive medicine at the Northwestern University’s Feinberg School of Medicine in Chicago.

“Our results highlight the importance of screening for blood pressure in childhood and focusing on strategies to promote optimal cardiovascular health beginning in childhood.”

Previous research has shown that childhood blood pressure is associated with an increased risk of cardiovascular disease in adulthood, and a 2022 study found that elevated blood pressure in older children (average age of 12 years) increased the risk of cardiovascular death by middle age (average age of 46 years).

The current study is the first to investigate the impact of both systolic (top number) and diastolic (bottom number) blood pressure in childhood on long-term cardiovascular death risk in a diverse group of children. Clinical practice guidelines from the American Academy of Pediatrics recommend checking blood pressure at annual well-child pediatric appointments starting at age 3 years.

“The results of this study support monitoring blood pressure as an important metric of cardiovascular health in childhood,” said Bonita Falkner, M.D., FAHA, an American Heart Association volunteer expert.

“Moreover, the results of this study and other older child cohort studies with potential follow-up in adulthood will contribute to a more accurate definition of abnormal blood pressure and hypertension in childhood.”

Falkner, who was not involved in this study, is emeritus professor of pediatrics and medicine at Thomas Jefferson University.

The researchers used the National Death Index to follow up on the survival or cause of death as of 2016 for approximately 38,000 chi
