New Delhi: It has been revealed in a new report that half of all cancer deaths in men in 2013 in China and more than a third of women were considered to be caused by potentially modifiable risk factors such as smoking, Alcohol, nutrition, weight, physical activity and infections.
The leading cause of death in China is cancer, with 4.3 million new cases and 2.8 million deaths estimated to occur each year. That burden is expected to increase in the coming decades due to population aging, as well as lifestyle changes that increase cancer risk, such as excessive calorie consumption and physical inactivity.
For further research, a multi-institutional team of researchers led by Farhad Islami of the American Cancer Society estimated the number and proportion of cancer deaths and cases attributable to smoking, alcohol consumption, and low fruit and vegetable consumption, Excess Of body weight, physical inactivity and infections in China, using contemporary data from nationally representative surveys and cancer registries.
Other researchers were from the National Cancer Center / Cancer Hospital, the Chinese Academy of Medical Sciences and the Union Medical College of Beijing, the NSW Cancer Council, Sydney, Australia, the University of Sydney, Emory University and the Imperial College of London.
They found 717,910 (52 percent) cancer deaths in men and 283,130 (35 percent) in women in 2013 in China were attributable to the risk factors considered in the analysis. The numbers corresponding to cancer cases were 952,520 (47 percent) in men and 442,650 (28 percent) in women. Between the two sexes combined, nearly one million (approximately 996,000) or nearly half of all cancer deaths and 1,388,800, or 39 percent of all cancer cases in China in 2013 were attributable to risk factors Studied.
“Our analysis probably underestimates the number of cancers attributable to modifiable risk factors because we could not include all potentially modifiable risk factors, particularly indoor air pollution from the use of charcoal for cooking and heating, which is an important factor Risk for lung cancer in women in China, “said Dr. Islami.
By risk factor, the highest attributable proportions of cancer deaths in men were for smokers (26 percent), hepatitis B (HBV) (12 percent), and low fruit and vegetable intake (seven percent). In women, HBV infection (seven percent), low fruit / vegetable intake (six percent), and exposure to secondhand smoke (five percent) were the largest contributors.
“Our findings reinforce the need for widespread implementation of known interventions and the development of new strategies to reduce exposure to established (smoking and carcinogenic) and emerging (alcohol, excess body weight and physical inactivity) risk factors.” country.”
The study appears in the Annals of Oncology and concludes that effective public health interventions to eliminate or reduce exposure to these risk factors can have a considerable impact on reducing cancer burden in China.
