摘　　要：AIM:To study the association of colorectal carcinoma(CRC) with diet,smoking,alcohol,physical activity,body mass index,family history and diabetes.METHODS: All consecutive patients with CRC confirmed by histopathology diagnosis were included. Age(±5 years) and gender matched controls were selected among the patients admitted in surgery ward for various conditions without any co-existing malignancy. Food frequency questionnaire(FFQ) was developed and validated after pretesting by investigator trained in data col ection techniques. Cases and controls were interviewed ensuring privacy,in similar interview setting,with same duration of time for both cases and controls without any leading question. Biological variables like family history of CRC in first degree relatives,history of diabetes mellitus; behavioral factors like tobacco use both smoking and smokeless form,alcohol consumption and physical activity were recorded. Dietary details were recorded using a FFQ consisting 29 food items with seven categories. Analysis was done using appropriate statistical methods.RESULTS: Ninety-four histopathologically confirmed cases of CRC and equal number of age and gender matched controls treated over a period of two years were studied. Age distribution,mean age,male to female ratio,education level and socioeconomic status were similar in cases and controls. Intake of food items was categorized into tertile due to skewed distribution of subjects as per recommended cut off for consumption of food item. On univariate analysis red meat [OR=7.4(2.935-18.732)],egg [OR=5.1(2.26-11.36)],fish,fried food and oil consumption were found to be risk factors for CRC. On multivariate analysis red meat consumption of more than 2-3 times a month(OR=5.4; 95%CI:1.55-19.05) and egg consumption of more than 2-3 times a week(OR = 3.67; 95%CI:1.23-9.35) were found to be independent risk factors for the development of CRC.CONCLUSION: Egg and red meat consumption found to be independent risk factors for CRC. Smoking,alcohol,physical activity and family history were not associated with increased risk. 关键词：DIETARY factors SMOKING RECTAL cancer Redmeat COLORECTAL MALIGNANCY
