By understanding what factors predict longevity, you can take control of your life before it is too late. Biostatisticians in the USA examined data from the National Health and Nutrition Survey (NHANES) to compare the predictive value of 15 potential longevity markers. The winner was the amount of physical activity you perform in a typical day as measured by a wrist tracker.
It can be difficult to get a true picture of how much physical activity people actually get from self reporting or old style pedometers. This study used wrist accelerometers worn day and night between 2011 and 2014. 3,600 subjects between the ages of 50 and 80 were tracked.
The factors that were examined were: Age, gender, body mass index, race or ethnicity, educational level, alcohol consumption, smoking, diabetes, heart disease, congestive cardiac failure, stroke, cancer, mobility problems and self reported overall health.
In order of importance, the best predictors of living longer were: Physical activity, age, mobility problems, self-assessed health, diabetes and smoking. In a nutshell, how much and how vigorously you move are more important predictors of longevity than how old you are.
In 2016, the American Heart Association, realised that VO2 Max was a very important measure of cardiorespiratory fitness. They noted that a low VO2 Max tended to be stronger predictor of mortality than smoking, cholesterol levels and high blood pressure. VO2 Max is determined to the tune of 50% by your genes, whereas how much you move is up to you. (There are indeed “sporty” families!)
So get up, get out, and get moving, as much as you can.
In a separate study published in Cognitive Science, Dementia, an article written by Eric Dolan on 27 March 20025 states that verbal fluency was the most important factor regarding freedom from dementia.
