Colorectal cancer: physical activity, obesity and consumption of foods a case-control study in the east of Algeria

Abstract

Purpose: To evaluate the role of dietary components, physical activity, smoking and Obesity in colorectal cancer. Materials and methods: With a population-based case-control study, 49 colorectal cancer patients and 72 controls were interviewed with uniform questionnaires. Conditional logistic regression was used for multivariate analysis of colorectal cancer. A total of 121 pairs of case controls were interviewed. Results: Relationship between body mass index (BMI) and colorectal cancer was shown in this study, obesity was shown in 21 patients (42.86) before cancer and in 0% of patients during colorectal cancer. Physical activity was a significant risk factor p < 0.0001. Malnutrition was noted in 48 patients (97. 96%) according to Brachial muscular circumference in patients with colorectal cancer (p = 0.002). Daily consumption of sugar Khi² of Wald (5.423) and butter Khi² of Wald (7.694) is higher in cases than in controls. During that time, high daily consumption of pasta (p = 0.018) and vegetables (p = 0.045) was a protective factor for colorectal cancer. Conclusion: Colorectal cancer in Algeria was related to dietary and environmental factors. The research results support the colorectal cancer etiological hypothesis of deficiency vegetable and high consumption of lipids and sugar. Obesity and lack of physical activity were also correlated with colorectal cancer.
