ABSTRACT
Objective To analyze the impact of low whole grain intake on the burden and trend of colorectal cancer in China, and to explore health management strategies for high-risk populations. Methods Using the 2019 Global Burden of Disease Study (GBD 2019) data, the Joinpoint regression model was used to analyze the mortality rate and disability adjusted life years (DALYs) of colorectal cancer in China caused by low whole grain intake from 1990 to 2019. Results The number of colorectal cancer deaths, mortality and DALYs of residents over 70 years old caused by low whole grain intake in China increased from 4 615, 12.06/105 and 187.66/100 000 in 1990 to 21 094 , 19.54/100 000 and 291.02/100 000 in 2019. The trend analysis found that the total crude mortality rate of colorectal cancer in Chinese residents over 70 years old caused by low whole grain intake increased by 2.03% year by year, with men increasing by 2.61% year by year, and women increasing by 1.24% year by year (all P<0.001). From 1990 to 2019, the disease burden of colorectal cancer in China was higher than that of countries with middle, low-middle, and low SDI, but lower than the global average, and high and middle-high SDI countries or regions. The growth rate in China was higher than the above regions (China 1.86% vs. global -0.25%, high SDI -0.88%, middle-high SDI -0.09%, middle SDI 1.53%, low-middle SDI 1.12%, and low SDI 0.63%). Conclusion Based on the current situation and trend of colorectal cancer disease burden of residents over 70 years of age in the world and China, precise health management of unhealthy lifestyles of high-risk populations will help to achieve the goals of healthy aging and healthy China 2030.
