Study Quantifies Genetic Risk of Hypertension Across Lifespan

According to researchers at the Norwegian University of Science and Technology, high blood pressure occurs in all age groups and is related to hereditary factors. The team’s research, published in the European Journal of Preventive Cardiology, underscores that genetic factors influence blood pressure from childhood through adulthood. High blood pressure, a leading cause of heart attacks and strokes, is closely tied to our genetic makeup, with lifestyle and environmental factors also playing significant roles.

By analyzing genetic data from large population studies, researchers have developed a genetic risk score to assess individual susceptibility to high blood pressure. This score assigns values to gene variants based on their impact on blood pressure, enabling the identification of individuals at heightened risk. Early intervention based on genetic risk scores can potentially reduce disease risk significantly.

The study draws on health data from extensive population studies like the HUNT Study and the Children of the 90s study, revealing that individuals with a high genetic risk score exhibit elevated blood pressure from early childhood, persisting into adulthood. The differences in blood pressure between high and low-risk individuals remain consistent throughout life, impacting disease susceptibility.

While genetics play a crucial role in blood pressure regulation, lifestyle modifications and medications can effectively mitigate disease risks associated with hypertension. By maintaining optimal blood pressure levels, individuals with a high genetic risk score can lower their disease susceptibility compared to those genetically predisposed but diagnosed with high blood pressure.
