The Most Shocking Underrated Mortality Risk Factor

The full list of the top 10 factors that most strongly predict death is as follows:
smoking (currently)
history of divorce
history of alcohol misuse
recent financial difficulties
history of unemployment
smoking (previously)
lower life satisfaction
never having been married
history of using food stamps
negative affectivityA recent estimate of U.S. life expectancy stood at 78.6 years, while 11 other industrialized nations averaged about 82.3 years. This represented a gain of just 4.9 years for the U.S. between 1980 and 2017, while other nations added an average of 7.8 years.
Biological and medical factors are likely part of the reason, and advances in medicine that aim to address these factors continue. The roles of social, psychological, economic, and behavioral factors in life expectancy are less well understood, and researchers often study them in isolation.
This means that it is unclear which of these nonmedical factors are the strongest predictors of mortality risk — a knowledge gap the new study hoped to fill.
The study, which Eli Puterman of UBC led, included the data of 13,611 adults who took part in the U.S. Health and Retirement Study. This was a nationally representative sample of U.S. adults aged 52–104. The average age was 69.3. Scientists collected these data between 1992 and 2008 and analyzed them in relation to deaths that occurred between 2008 and 2014Smoking can increase the likelihood of having a stroke by 2–4 timesTrusted Source. Strokes can cause brain damage and death.
One way that stroke can cause brain injury is through a brain aneurysm, which occurs when the wall of a blood vessel weakens and creates a bulge. This bulge can burst and cause a subarachnoid hemorrhage, which can lead to a stroke.

They found that people who get less than two and a half hours of physical activity per week have an increased risk of mortality and serious health issues, including: • Breast cancer • Cardiovascular disease • Diabetes • Insulin resistance • Gallstones • Colon cancer • Stroke • Decreased cognitive function • Mood problems • Problems with cholesterol • Higher activation of the sympathetic nervous system • Increased inflammation Regular exercise activates certain genes that increase your health and survival. But it’s important not to overtrain because overtraining can keep your body inflamed.
