JAMA sub-issue: 2.5 hours of activity per week, the risk of death has dropped by nearly 70%!

The global population of cancer survivors is growing rapidly due to technological advances in early cancer screening and treatment
.

Many cancers and cancer treatments can have adverse effects and shorten the life expectancy of cancer patients

Numerous studies have shown that physical activity is associated with a reduced risk of common chronic diseases and improved cancer survival before and after diagnosis

Evidence suggests that the health effects of physical activity in cancer survivors are more pronounced than before cancer diagnosis
.

What are the independent and common associations of daily sedentary time and physical activity with mortality outcomes among cancer survivors in the United States? This issue remains unresolved

Health Effects of Physical Activity in Cancer Survivors More Significant Than Before Cancer Diagnosis What are the independent and common associations of daily sedentary time and physical activity with mortality outcomes among cancer survivors in the United States? This issue remains unresolved

This study aimed to investigate the independent and joint associations of daily sedentary time and leisure time physical activity with mortality outcomes in cancer survivors

The study population was derived from a prospective cohort of a nationally representative sample of cancer survivors from the National Health and Nutrition Examination Survey 2007-2014, aged 40 years or older (n = 1535; weighted population, 14,002,666)
.

Participants were associated with mortality data from the date of interview and physical examination through December 31, 2015

The main outcomes and indicators were

The mean [SE] age of the 1535 cancer survivors was 65.
1 [0.
4] years, of whom 828 [60.
1%] were female
.

Of 945 [83.

The mean [SE] age of the 1535 cancer survivors was 65.

Notably, 574 (35.

Physical activity was associated with a 66% lower risk of all-cause mortality compared to inactivity, a 68% lower risk of cancer-specific mortality , and an 81% higher risk of all-cause mortality by sitting less than 4 hours a day for more than 8 hours a day 127%

In a combined analysis, prolonged sitting and lack of adequate activity were associated with an increased risk of death in cancer survivors
.

Specifically, inactive and underactive survivors were associated with overall mortality (HR = 5.

Long-term sitting and lack of adequate activity are associated with an increased risk of death in cancer survivors

Overall, a combination of sedentary and physical inactivity was common in this cohort study of a nationally representative sample of U.
S.
cancer survivors
.
The researchers found that sedentary and physical inactivity in cancer survivors was associated with an increased risk of all-cause and cancer death
.
Future research is needed to elucidate these associations further, and substantial evidence is needed to quantify the timing, dose, restriction, and type of sedentary behavior and physical activity to increase survival among cancer survivors
