Background: Colorectal cancer (CRC) is one of the most prevalent malignancies worldwide, particularly affecting the elderly. Tertiary prevention—focused on nutrition and lifestyle—may play an important role in improving treatment outcomes and quality of life. This exploratory study aimed to describe dietary and lifestyle behaviors among CRC patients, considering age, body mass index (BMI), and educational background as potential differentiating factors.Methods: A cross-sectional study was conducted among 202 CRC patients using a validated paper-based questionnaire. Sociodemographic data and health behaviors were analyzed using chi-square tests.Results: Age-related differences revealed that middle-aged patients consumed vegetables and legumes more frequently but also reported higher fast-food intake. Elderly individuals more often abstained from alcohol and tobacco. Overweight and obese participants were more likely to consume meat and sweets regularly and preferred frying over other cooking methods. Higher education was associated with lower rates of smoking and alcohol use.Conclusions: The findings suggest that dietary and lifestyle profiles among CRC patients may vary by age, BMI, and education. While causal relationships cannot be established, the results may help generate hypotheses for future research and support the development of individualized tertiary prevention strategies.
背景：结直肠癌是全球范围内最常见的恶性肿瘤之一，尤其影响老年人群。以营养和生活方式为重点的三级预防可能在改善治疗效果与生活质量方面发挥重要作用。本探索性研究旨在描述结直肠癌患者的饮食及生活方式行为，并将年龄、体重指数及教育背景作为潜在差异化因素进行考量。 方法：采用经过验证的纸质问卷对202名结直肠癌患者开展横断面研究。通过卡方检验分析社会人口学数据与健康行为特征。 结果：年龄相关差异显示，中年患者摄入蔬菜和豆类的频率更高，但同时报告了更高的快餐摄入量。老年群体更倾向于戒除烟酒。超重及肥胖参与者更经常摄入肉类和甜食，且相较于其他烹饪方式更偏好油炸食品。高等教育背景与较低的吸烟率和饮酒率相关。 结论：研究结果表明，结直肠癌患者的饮食及生活方式特征可能因年龄、体重指数和教育背景而异。虽然无法建立因果关系，但这些发现有助于为未来研究提供假设依据，并支持制定个体化的三级预防策略。
