Due to the continuous advancement of early cancer screening and treatment technology, the population of global cancer survivors is growing rapidly.Many cancer and cancer treatment have a poor effect and shorten the life expectancy of cancer patients.Therefore, it is urgent to formulate feasible strategies to improve the long -term health of cancer survivors.Physical activity has always been considered a healthy lifestyle. Many studies have shown that physical activity is related to the reduction of the risk of common chronic diseases, and it can also increase the survival rate of cancer before and after confirmation.
Evidence shows that the health effect of cancer survivors’ physical activity is more significant than before the diagnosis of cancer.What are the independent and common relationship between the daily sitting time and physical activity of the American cancer survivor?This problem has not been resolved.
This study aims to explore the independence and joint association of cancer survivors daily and leisure and physical activity with the ending of mortality.
This research crowd comes from the forward-looking queue of national representative cancer survivor samples from 2007-2014 to the national health and nutritional inspection survey, aged 40 or above (n = 1535; weighted population, 14,002 666).Participants from interviews and physical examination dates to December 31, 2015 are associated with mortality data.Sitting daily and leisure time physical activity (LTPA) uses the global physical activity questionnaire self -reporting.The main ending and indicators are full causes, cancer specificity and non -cancer mortality.
1535 cancer survivors average [SE] age is 65.1 [0.4], of which 828 [60.1%] are women.945 [83.1%] Among the non -Spanish white individuals, 950 (56.8%) reported that the LTPA in the previous week (non -activity) was 0 minutes (minute/week) per week, and 226 (15.6%) reported that the LTPA was lower than 150Minutes/week (not active enough); 359 (27.6%) reported that the LTPA was 150 minutes/week or longer (active).553 (35.4%) report to sit 6 to 8 hours (h/day) a day; 328 people (24.9%) report reports 6 to 8 hours (h/day); 328 (24.9%) report reports for more than 8 hours./sky.
It is worth noting that 574 (35.8%) cancer survivors reported that there was no LTPA, and the time for a long time was more than 6 hours/day.During the 9 -year follow -up period (median, 4.5 years; 6980 years), a total of 293 people died (cancer, 114; heart disease, 41; other reasons, 138).
The multi-variable model shows that compared with non-activity, physical activity is related to the risk of death by 66% (risk ratio [HR]; 95% CI: 0.20-0.60), and the risk of the risk of cancer-specific mortality is reduced by 68 68% (HR = 0.32; 95% CI: 0.15-0.70).Compared with patients with a sedentary time of less than 4 hours a day, the full risk of death by 81% (HR = 1.81; 95% CI: 1.05-3.14) of patients with more than 8 hours per day is127% high (HR = 2.27; 95% CI: 1.08-4.79)!
In joint analysis, long -term sitting is related to the increase in the risk of death in the lack of activity.Specifically, survivors who do not move and lack of activity sit for more than 8 hours a day (HR = 5.38; 95% CI: 2.99-9.67) and cancer specific mortality (HR = 4.71; 95% CI: 1.60-13.9) The highest.
In general, in the study of the national representative samples for American cancer survivors, the combination of sedentary and lack of physical activity is very common.Researchers have found that the survivors of cancer and lack of physical activity are related to the increase in the risk of cancer death.In the future, research needs to be further clarified, and a lot of evidence is required to quantify the time, dose, restrictions and types of physical activity and physical activity to increase the survival rate of cancer survivors.
