Navigating Blood Pressure for Longevity: Insights from the Women's Health Initiative
A recent exploration into systolic blood pressure (SBP) and its impact on longevity reveals intriguing findings for women aged 65 and older. The study investigated the optimal SBP range that correlates with the highest likelihood of living to 90 years of age. It was found that maintaining an SBP between 110 and 130 mm Hg significantly enhances survival prospects, reinforcing the idea that carefully managed blood pressure can serve as a key component in healthy aging strategies.
The research analyzed the health data of over 16,000 women, tracking their SBP over several years while observing their health outcomes. Results indicate that women maintaining SBP within the target range had increased probabilities of reaching nonagenarian status compared to those with higher SBP levels. This finding suggests a clear link between controlled blood pressure and extended lifespan, offering a compelling argument for regular monitoring and management of blood pressure in elderly populations.
The study's conclusions support existing guidelines that recommend an SBP target of less than 130 mm Hg for older women. By adhering to these guidelines, it's possible to not only enhance longevity but also improve the quality of life during the golden years, making a strong case for hypertension management as a cornerstone of preventive healthcare in aging.

Systolic Blood Pressure and Survival to Very Old Age: Results From the Women's Health Initiative
Published in Circulation. Bernhard Haring et al.
Abstract
Background: The relationship between systolic blood pressure (SBP) and longevity is not fully understood. We aimed to determine which SBP levels in women ≥65 years of age with or without blood pressure medication were associated with the highest probability of surviving to 90 years of age.
Methods: The study population consisted of 16 570 participants enrolled in the Women's Health Initiative who were eligible to survive to 90 years of age by February 28, 2020, without a history of cardiovascular disease, diabetes, or cancer. Blood pressure was measured at baseline (1993 through 1998) and then annually through 2005. The outcome was defined as survival to 90 years of age with follow-up. Absolute probabilities of surviving to 90 years of age were estimated for all combinations of SBP and age using generalized additive logistic regression modeling. The SBP that maximized survival was estimated for each age, and a 95% CI was generated.
Results: During a median follow-up of 19.8 years, 9723 of 16 570 women (59%) survived to 90 years of age. Women with an SBP between 110 and 130 mm Hg at attained ages of 65, 70, 75, and 80 years had a 38% (95% CI, 34%-48%), 54% (52%-56%), 66% (64%-67%), or 75% (73%-78%) absolute probability to survive to 90 years of age, respectively. The probability of surviving to 90 years of age was lower for greater SBP levels. Women at the attained age of 80 years with 0%, 20%, 40%, 60%, 80%, or 100% time in therapeutic range (defined as an SBP between 110 and 130 mm Hg) had a 66% (64%-69%), 68% (67%-70%), 71% (69%-72%), 73% (71%-74%), 75% (72%-77%), or 77% (74%-79%) absolute survival probability to 90 years of age.
Conclusions: For women >65 years of age with low cardiovascular disease and other chronic disease risk, an SBP level <130 mm Hg was found to be associated with longevity. These findings reinforce current guidelines targeting an SBP target <130 mm Hg in older women.
