Background Colorectal cancer (CRC) has emerged as a major public health concern. However, little is known about the burden attributable to specific risk factors. The present study aimed to estimate the temporal trends and geographical variation of CRC burden attributable to a diet low in milk in China. Methods Following the general analytic strategy used in the 2017 Global Burden of Disease study, we assessed the age‐, sex‐, and province‐specific mortality and disability‐adjusted life‐years (DALYs) of CRC caused by a diet low in milk in China from 1990 to 2017. Results In 2017, a diet low in milk contributed 32 032 [95% uncertainty interval (UI) = 11 350–53 806] deaths and 726 710 (95% UI = 256 651–1 218 153) DALYs for CRC with a population attributable fraction of 17.1%. The age‐standardised mortality and DALY rates per 100 000 were 1.7 (95% UI = 0.6–2.9) and 36.8 (95% UI = 13.0–61.7), respectively. An upward trend with age in rates of mortality and DALYs was observed. Males had higher age‐standardised rates than females. The number of deaths and DALYs increased significantly from 1990 to 2017, whereas the corresponding age‐standardised rates showed relatively stable trends. In 2017, Hunan and Liaoning were ranked as the top two provinces in terms of disease burden. Socio‐demographic index had a weak correlation with the age‐standardised mortality ( r = 0.348, P = 0.047). Conclusions The present study shows a substantial increase in the CRC burden attributable to a diet low in milk over the past three decades. Greater priority in CRC prevention should be given to males and the elderly population throughout China, particularly in less‐developed provinces.
