A comprehensive study conducted at Oxford University examining 1.4 million adults in England found significant gaps in the detection and management of high blood pressure, according to research published in BMJ Public Health. The investigation, which analyzed data from the Our Future Health programme involving participants enrolled between 2022 and 2025, defined high blood pressure as readings of 140/90 mmHg or higher.
The research determined that approximately 37% of adults have high blood pressure, with roughly 59% of this population unaware of their condition. Among those diagnosed and receiving medication through their general practitioner, only 50% achieved adequate blood pressure control. Study authors noted that hypertension occurred nearly 50% more frequently in men compared with women, with rates of 42% and 29% respectively across all age groups, and increased prevalence in older populations.
Researchers characterized these findings as indicating that current detection and treatment approaches in England are not meeting public health needs. They observed that while substantial progress occurred during the 2000s in identifying and controlling high blood pressure, advancement plateaued around 2011. The study also noted potential deterioration following the Covid-19 pandemic, with researchers suggesting that healthcare delivery disruptions may have produced lasting consequences.
Experts attributed the challenges in achieving blood pressure control to multiple factors, including medication side effects, complicated treatment regimens, and lifestyle influences such as diet, salt intake, weight, alcohol consumption, and physical activity levels. Some patients require dosage adjustments or combination therapies involving multiple medications. Researchers acknowledged study limitations, including the absence of independent prescribing records to verify medication adherence and reliance on single blood pressure measurements rather than typical readings.
Public health officials called for expanded prevention strategies and improved approaches to identifying and supporting individuals at cardiovascular risk, noting that better detection and treatment could prevent substantial numbers of heart attacks and strokes.
