Abstract

A case-control study was conducted in order to examine dietary behavioral factors associated with colorectal cancer risks. Data were collected from 128 cases with either colorectal cancer or large bowl adenomatous polyps and 129 controls regarding stages of dietary behavioral change, perceived barrier, self efficacy, nutrition knowledge, social support and food availability as well as body mass index and overall dietary quality. Cases showed less desirable behaviors with respect to fat reduction and vegetable intake compared with controls based on the analyses of the stages of dietary change. After adjustment of relevant covariates (age, gender and smoking), significant trends of increasing risk with higher level emerged for perceived barriers resulted from environmental conditions (OR = 1.6 - 2.0) and self-efficacy (OR = 2.2-2.3). No such relationships were found for nutrition knowledge and social support. The risk of colorectal cancer was associated with the kinds of foods available at home showing a borderline protective relation with milk (OR = 0.6) and respective significant and borderline direct associations for fresh meat (OR = 2.1) and soft drinks (OR = 0.6 when reversely scored). Within-group analyses presented best predictors of overall dietary quality as food availability for the case and self-efficacy and social support for the control. The findings of this study suggested a need for focusing on motivational and reinforcing factors in the development of nutrition education programs for colorectal cancer prevention.
