Evaluation of Knowledge, Attitudes, and Practices towards Colorectal Cancer in a Community in Mexico City: A Cross-Sectional Study Based on Surveys.

Abstract

Colorectal cancer (CRC) is one of the most common and deadly neoplasms worldwide, with a growing burden in low- and middle-income countries, such as Mexico. This study seeks to evaluate the knowledge, attitudes, and practices related to CRC in a community in Mexico City. A cross-sectional survey was conducted between March and April 2023 among adults aged 45 to 74 residing in six neighborhoods of the Tlalpan borough in Mexico City. The questionnaire included sections on sociodemographic characteristics, medical family history, lifestyle habits, knowledge about CRC, attitudes towards prevention, and willingness to undergo screening. Data were analyzed using logistic regression models to identify factors associated with greater knowledge, attitudes, and practices. A total of 349 people were surveyed. A total of 35.2% reported knowing what CRC is, with greater knowledge of CRC being associated with higher education levels and having a family history of cancer. A total of 23.8% showed positive attitudes towards CRC screening, influenced by having a tertiary level of education. A total of 80.8% of participants expressed willingness to undergo CRC screening if offered, with lower intention observed among men. Levels of knowledge about CRC within the studied community are low, especially among those with lower education levels and without a family history of cancer. Intervention strategies should improve CRC education and foster positive attitudes towards early detection, particularly in high-risk groups.
