A groundbreaking study, spanning nearly five decades, has yielded valuable insights into the impact of five specific health factors on mortality rates and overall longevity. Published in the New England Journal of Medicine, the study’s results demonstrated the significant influence of these factors on an individual’s lifespan and cardiovascular health.
Riveting findings from the study include the potential for women to extend their lives by over 14 years and men by approximately 12 years by avoiding the five identified risk factors at age 50. The research highlighted the particularly pronounced challenges faced by men in this regard, with those affected by all five risk factors facing a 94% likelihood of premature death compared to 68% for their healthier counterparts.
Moreover, women with all five risk factors at age 50 were found to have an 88% chance of premature death, while those without the identified issues had a substantially lower 53% probability. Additionally, individuals with all five risk factors at the age of 50 faced a significantly elevated risk of developing cardiovascular disease, with the potential increase reaching up to 38%.

The study revealed varying impacts of the five factors, with cholesterol demonstrating the smallest effect on lifespan. Notably, reducing high cholesterol levels contributed only 1.2 additional healthy years to an individual’s life. In contrast, abstaining from smoking could potentially add up to six years to one’s lifespan.
The significance of reducing blood pressure, achieving a healthy BMI, and managing diabetes was also underscored in the study. Modest reductions in blood pressure were associated with an increase of up to 1.8 healthy years, while attaining a normal BMI range offered an additional 2.6 years, contingent on the region.
Notably, the study’s extensive scope encompassed data from over two million individuals aged 18 and above across 39 countries. The research further emphasized that individuals above the age of 50 still have the opportunity to enhance their longevity, as positive changes during this stage, such as ceasing smoking or addressing multiple risk factors, could contribute to the addition of several years to their lifespan.
In conclusion, the study’s researchers emphasized that the absence of the five identified risk factors at the age of 50 was associated with over a decade of increased life expectancy, irrespective of gender. They further highlighted the pivotal impact of modifying hypertension and smoking in midlife, which was linked to substantial additional years free from cardiovascular disease and mortality.
