Abstract: Objective The aim of this study was to understand the high risk rate of liver cancer among permanent residents in Suzhou city, analyze the dietary related influencing factors of high risk of liver cancer, and propose feasible prevention and control suggestions based on this. Methods In 2021,8 townships and streets were selected through cluster sampling in urban areas of Suzhou city, and a questionnaire survey was conducted using the "Cancer Risk Assessment Questionnaire (2020 Edition)" from the Jiangsu Cancer Screening Project. The high-risk rate of liver cancer among residents with different characteristics were compared, and the impact of dietary related factors on the high risk of liver cancer were analyzed. Results In 2021, a total of 3 073 valid questionnaires were collected in urban areas of Suzhou city, of which 727 were high-risk individuals for liver cancer, accounting for 23.7% of the total population. The results of multivariate logistic regression analyses showed that consumption of meat, eggs, dairy products, fried foods, and processed meat were significantly associated with a high risk of liver cancer (P＜0.05). Conclusion The consumption of processed meats and fried foods is associated with a high risk of liver cancer, and daily consumption of meat, eggs, and milk can reduce the risk of liver cancer. Interventions targeting these dietary behaviors may help reduce the risk of liver cancer.
