Background: Given the role of behavior in the prevalence of breast cancer, the present study was conducted to determine the predictors of adopting preventive nutritional behaviors against breast cancer based on social-cognitive theory ( SCT ) variables in women of reproductive age in Davarzan city in ۲۰۱۷.   Methods: This is a cross-sectional (descriptive-analytical) study conducted on ۱۶۰ women of reproductive age in Davarzan, Khorasan Razavi province, Iran. Data were collected by a researcher-made questionnaire and analyzed by Spearman, Kruskal-Wallis, Mann-Whitney U, and Linear Regression tests using SPSS ۱۸ software.   Results: The mean age of participants was ۳۲.۶ ± ۹.۳۲ years. The results showed that among SCT variables, only the variable of awareness had a significant correlation with behavior (P=۰.۰۴, r=۰.۱۵). These variable could predict ۱۲% of the changes in the preventive nutritional behaviors of breast cancer in women (R۲=۰.۱۲, p <۰.۰۰۱).   Conclusion: Considering the findings of the present study, in developing educational interventions to increase preventive nutritional behaviors of breast cancer, more focus on women’s awareness is suggested.
