Lifestyle Changes Significantly Reduce Heart Disease and Diabetes Risk for Those with High Blood Pressure
Maintaining or improving healthy habits after a high blood pressure diagnosis can substantially lower the risk of developing cardiovascular disease and type 2 diabetes, according to a new study. The research, published in JAMA Network Open on March 18, 2026, highlights the importance of proactive lifestyle management alongside medical treatment.
Hypertension affects approximately one-third of adults worldwide and, despite advancements in medication, remains a leading cause of cardiovascular and metabolic diseases and premature death. This study adds to a growing body of evidence demonstrating the preventative benefits of lifestyle factors, but specifically examines their impact on individuals already diagnosed with high blood pressure.
Researchers from Harvard T.H. Chan School of Public Health tracked over 25,000 adults newly diagnosed with hypertension for up to 30 years. They assessed participants’ adherence to healthy habits – including diet, exercise, weight management, smoking status, and alcohol consumption – using a “Healthy Lifestyle Score” (HLS).
The findings revealed that individuals in the highest HLS group (a score of 5) had a 51% lower risk of cardiovascular disease compared to those in the lowest group (a score of 0-1). The risk of developing type 2 diabetes was approximately 79% lower in the highest HLS group. This suggests that even after a diagnosis, adopting healthier habits can have a profound impact on long-term health outcomes.
The study likewise examined the consequences of declining healthy habits. According to recent reports, individuals who maintained healthy lifestyles before their diagnosis but saw those habits decline afterward experienced a 14% increase in cardiovascular disease risk and a 75% increase in diabetes risk.
These findings reinforce the idea that managing lifestyle factors is crucial, even for those already receiving medical treatment for hypertension. Experts emphasize that the benefits of lifestyle changes are seen regardless of whether or not patients are taking medication for high blood pressure, suggesting that a combined approach is optimal for protecting cardiovascular and metabolic health.
The research was based on data from the Nurses’ Health Study (NHS 1986-2014) and the Health Professionals Follow-up Study (HPFS 1986-2014). Further details on the study can be found in the Yonhap News Agency.
This research underscores the importance of prioritizing preventative health measures and empowering individuals with high blood pressure to take control of their well-being through sustainable lifestyle changes. The findings could inform public health initiatives aimed at promoting heart health and diabetes prevention.
