Introduction: According to the World Health Organization (WHO) data from 2022, 19.9 million people were diagnosed with cancer globally, and 9.7 million people died from the disease. In recent years, the incidence of colorectal cancer (CRC) has been rapidly increasing, ranking 4th among all cancers with 18.4 cases and 8.1 deaths per 100,000 population. In Mongolia, 826 new cases of CRC have been registered over the past six years, with an incidence rate of 8.2 cases and a mortality rate of 5.03 per 100,000 population. It is projected that by 2030, the incidence will reach 13.28 cases and the mortality rate will rise to 8.72 per 100,000 population. We aimed to comprehensively examine the risk factors for colorectal cancer among the population of Mongolia, establish a scientific basis for early detection and prevention, and strengthen preventive measures. Materials and Methods: A case-control study was conducted from 2022 to 2024. The study enrolled a total of 305 subjects, including 98 patients with colorectal cancer, 101 patients with colon polyps, and 106 healthy subjects. The risk. questionnaire consisted of 50 questions divided into 10 sections. All statistical analysis was performed with SPSS version 23.0 software (SPSS Inc., Chicago, IL, USA) and P value <0.05 was considered statistically significant. categorical data was represented as numbers and percentages. Pearson’s chi-squared and Fisher’s exact test were used to compare categorical variables. Multivariate logistic regression was used to identify the risk factor associated with recurrence. The study protocol was approved by Ethics Review Committee of Ministry of Health of Mongolia on 17 March 2023 (approval number: 23/012). Results: The average age of the participants was 57.1±12.8 years. Among all study participants, 37.6% (115) were male and 62.4% (188) were female. Comparison of colorectal cancer incidence by age and gender revealed no statistically significant differences (p=0.021; p=0.422). Regular physical exercise was found to have a protective effect against colorectal cancer (p=0.076; OR 0.341 95% Cl 0.118-.0986). The frequency of fruit consumption, 4 to 6 times per week (p=0.008, OR 0.08, 95% Cl 0.01-0.45), frequency of vegetable consumption 4 to 6 times per week (p<0.00; OR 0.07, 95% Cl 0.02-0.19), no dining out (0.007, OR 0.3, 95% Cl 0.18-0.68), and meat consumption (p=0.001) are decreased risk of colorectal cancer. Conclusion The patient's age and the presence of colon polyps are risk factors for colorectal cancer, while regular physical activity and a diet rich in fruits and vegetables are protective factors that help reduce the risk of developing colorectal cancer.

Introduction: Cancer continues to be one of the world’s major health issues, with Mongolia continues to lead Asia in esophageal (100’000: 17.1) and gastric cancer incidence (100’000: 41.0). In the previous decade, 8,137 new cases of gastric cancer were reported in Mongolia. According to TNM staging, eight out of every ten people are diagnosed late, recognizing the need to improve people’s knowledge, attitudes, and practices. Methods: The survey was carried out using a questionnaire. A total of 320 participants between 17- 80 ages from the aimags of Uvs, Khovd, and Zavkhan were chosen at random for the survey, and data was collected through social media. SPSS (v28.0, SPSS Inc., Chicago, IL, USA) software was used for statistical analysis. Results: The survey included 110, 106, and 104 participants from the aimags of Uvs, Zavkhan, and Khovd. A total of 320 participants, with 20.9% (67) and 79.1% (253) being male and female respectively. The average age was 35.56±9.15 years. The participants’ mean knowledges, attitudes and practices scores were 7.54±2.7, 9.6±2.2, and 3.82±1.1 respectively in the first survey. Following the advocacy campaign, the mean knowledge, attitude, and practice scores increased to 9.3±2.7, 10.1±2.2, and 4.00±1.2, respectively. Conclusion The attitudes and practices of the participants were related to their level of knowledge. It is critical to increase health education and advocacy efforts in order to develop the appropriate attitudes and behaviors to reduce cancer-related deaths.
