ABSTRACT
Colorectal cancer is the third common malignancy in the world. Personal habits including life style and nutrition have been proposed as risk factors of colorectal cancer. We conducted this study to assess the nutritional characteristics in colorectal cancer patients in Golestan province of Iran. This case-control study was done on 47 colorectal cancer cases, diagnosed during 2004-05 and 47 healthy controls. A questionnaire containing socio-demographic and nutritional characteristics [FFQ] was filled for each of the participants. Chi square test was used to assess the relationship between variables. In each of the two groups, 40.4% were females and 59.6% were males. The mean +/- SD age of age in cases and controls were 52.4 +/- 13.4 and 52.1 +/- 13.1 years, respectively. Total energy expenditure of higher than 1837.5 Kcal/day was significantly related to colorectal cancer [OR= 3.8; 95% CI: 1.2-11.3]. Colorectal cancer risk was higher in individual with frying cooking method [OR=3; 95% CI: 0.8-11.1]. The risk of colorectal cancer was 6.5 times higher in individuals with fat consumption of higher than 118.5 grams/day [95% CI: 1.5-28.8].No significant relationship was seen between vegetables consumption and the risk of colorectal cancer. This study showed that high total energy expenditure, high fat consumption and using frying method for cooking are risk factors of colorectal cancer in Golestan province in Northern of Iran
