Analysis of the nutritional, epidemiological and pathological profiles in 34 cases of CRC in Jijel region

Abstract

To study the relations between some lifestyle factors, some food groups’ frequency consumption and CRC in Jijel region, north east of Algeria, we conduct a case control study among CRC patients of the hospital Mohamed Seddik Ben Yahya in Jijel, using a lifestyle questionnaire and a food frequency questionnaire. Comparing 34 cases with 34 controls revealed that high educational level (OR= 0.0578, p-value= 0.0075), low household income (OR= 7.8386, p value= 0.0374), smoking (OR=0.0751, pvalue= 0.0174) and familial history of CRC (OR= 5.2500, p-value = 0.0034) may be associated with CRC occurence in this population. A protective effect of consumption of dairy products (OR= 0.9808, p-value= 0.0437) and cereals (OR= 0.9865, p-value= 0.0100) was observed whereas fish consumption seems to be associated positively with CRC (OR= 1.0665 , p-value = 0.0392).In conclusion, besides the fact that our results don’t indicate a major impact of diet on CRC incidence in the population of Jijel, this work represents an introduction to the study of the effect of environmental factors, mainly diet, on the occurrence of CRC between Algerians. Such studies will bring relevant approaches for primary prevention.
