Healthy nutrition and choice of physical lifestyle reduce the risk of cancer mortality for survivors, the study suggests

In 2022, the American Cancer Society (ACS) updated his Guidelines on nutrition and activity for cancer survivorsRecommending to avoid obesity, to remain physically active, to eat a healthy diet and to limit the supply of alcohol.

New research by ACS scientists show that a lifestyle aligned with these guidelines is associated with a lower risk of mortality in non-smoke-fumers of obesity in the United States. Survivors who maintained a healthy lifestyle Before and after their diagnosis – or those who improved their habits after diagnosis – also had a lower risk of mortality.

The study is published in the National Cancer Institute Journal.

“A cancer diagnosis often motivates people to think about how they can live a healthier life. Many survivors want to know what lifestyle changes they can bring to improve their chances of living longer,” said Dr. Ying Wang, main scientist, research of epidemiology to American Cancer Society and the main study of the study.

“These results emphasize how to make the right lifestyle choices really affect the survival of cancer.”

The researchers analyzed the lifestyle habits of non-smoking participants in the nutrition cohort of the cancer prevention study diagnosed with cancers linked to obesity between 1992 and 2002 to 2020.

Membership of post -diagnosis to ACS directives – body mass index (BMI), physical activity, food and alcohol consumption – was noted on a scale of 0 to 8. Models have been used to calculate multivariable adjusted risk ratios (HR) and 95% confidence intervals (CIS).

The results of the study showed that among 3,742 cancer survivors (67.6 years average) with median follow -up of 15.6 years, 2,430 deaths took place.

Survivors with a score of 6–8 had a 24% lower risk of all-main mortality (HR = 0.76; 95% CI = 0.68 to 0.85), A 33% Lower Risk of Cardiovascular Disease Mortality (HR = 0.67; 95% CI = 0.54 to 0.83), and a 21% Cancer-Specific Mortality (HR = 0.79; 95% CI = 0.64 to 0.97) compared to those with a score from 0 to 3.

Higher BMI and physical activity The scores were associated with lower mortality. Compared to survivors with a regularly low ACS guideline score (less than 5) before and after diagnosis, those with a systematically high (five or more) score had a lower cause of illness and lower cardiovascular. In addition, the survivors who improved their score from low to high had a larger lower cause mortality.
