Low Cardiovascular Risk in Early Midlife Correlates with Better Late Life Health
Researchers here process data from a longitudinal study of several thousand people to show that better cardiovascular heath in the early 40s correlates with better outcomes in later old age. There are many reasons to put in the effort to maintain a better state of physical fitness, and that it meaningfully slows the pace of degenerative aging is one of them. In some metrics, such as odds of surviving until age 90, the spread of outcomes between least fit and most fit is sizable - a 6-fold increase in survival. It is food for thought for an age of sedentary comfort.
We examined how low cardiovascular risk in early midlife is associated with frailty, quality of life, happiness, and well-being in old age. At mean age of 42 years, five low-risk factors (non-smoking, BMI < 25 kg/m2, systolic blood pressure < 140 mmHg, total cholesterol < 6.0 mmol/L, one-hour post-load glucose < 9.0 mmol/L) were measured among 2,690 healthy men. Phenotypic frailty, health-related quality of life (HRQoL, RAND-36), psychological wellbeing, and feeling of happiness (a Cantril ladder-type 10 cm visual analogue scale) were assessed in 2007 at a mean age of 79 years. Mortality was retrieved from national registers through 31 January 2025 (2,524 men died).
At baseline, 59 men had zero, 422 one, 855 two, 832 three, 417 four and 105 five low-risk factors. The proportion reaching 90 years increased accordingly: 6.8%, 14.2%, 18.3%, 26.7%, 36.6%, and 41.9%. At mean age of 79 years (n = 907, response rate 63% and similar in baseline groups), compared to those with no low-risk factors in midlife, men with five factors had less frailty (2.2% vs. 24.5%), reported greater happiness (8.0 vs. 7.5), higher psychological wellbeing (55.1% vs. 39.0%), and better HRQoL in several domains. Thus low cardiovascular risk in early midlife was associated with greater longevity, less frailty, better quality of life, and higher levels of happiness and well-being in old age.
