Nutrition and Selected Lifestyle Elements as a Tertiary Prevention in Colorectal Cancer Patients.

Background: Nutrition and lifestyle elements can significantly support the therapeutic process in colorectal cancer (CRC) patients, which is the basis for tertiary prevention. The study aimed to assess the nutritional strategies and lifestyle of CRC patients and to determine differences in these behaviors depending on gender and age.

Methods: The study group included 202 CRC patients. The research was carried out in two hospitals and using the snowball method. The research tool was an original questionnaire. Data were processed in statistical programs. p < 0.05 was considered statistically significant.

Results: Patients reported many behavioral-nutritional side effects. Half of them did not use a therapeutic diet (n = 101; 50.0%). The majority of patients declared that they ate three meals a day (57.4%). Fruits and vegetables were mainly eaten raw (69.3%). Almost a quarter of patients were not physically active at all (22.3%). Men chose to fry meat significantly more often than women (27.7% vs. 19.3%) (p = 0.003). The elderly consumed fast food significantly less often than middle-aged (88.5% vs. 72.3%) (p = 0.03).

Conclusions: Patients showed both pro- and anti-health activities. The findings revealed several noteworthy disparities in dietary habits and lifestyle choices based on gender and age, indicating that these factors can significantly influence the health management of CRC patients. The patients' behaviors should be constantly monitored and intensified, especially through regular consultations and educational meetings with an oncology dietitian for nutritional tertiary prevention of chronic disease.
