چکیده انگلیسی:
Background: Colorectal cancer (CRC) represents a heterogeneous group of diseases characterized by uncontrolled growth and spread of abnormal cells in the body. CRC vary on the basis of both the biologic features of the disease and its associated lifestyle characteristics. The risk of CRC increases with several modifiable factors including obesity, physical inactivity, a diet high in red or processed meat, heavy alcohol consumption, and possibly inadequate intake of fruits and vegetables. We aimed to establish a baseline data for dietary and lifestyle characteristics of Omani adults diagnosed with CRC. Methods: A Case control study conducted at Sultan Qaboos University Hospital, a referral hospital for CRC patients in Oman, and included 279 subjects (109 diagnosed CRC cases and 170 matched controls). All study subjects were recruited on volunteer basis and personally interviewed for preset questions related to sociodemographic data, anthropometric assessment, dietary intake and physical activity. Results: There was no significant difference between cases and controls regarding smoking, alcohol intake, physical activity and dietary fiber intake. However the enrolled cases were more overweight (OR =3.27. 95% CI: 1.91, 7.27), and, had a higher caloric (p =0.001) and macronutrient intake (carbohydrate: p = 0.001; protein: p = 0.017; saturated fat: P = 0.034) than the controls. In addition, the dietary pattern of the cases was characterized by a trend towards low vegetables and fruits intake. Conclusion: CRC maybe prevented through dietary management of high risk groups. This primary prevention approach will ultimately reduce the burden of CRC in Oman.
