Objectives: To examine gender differences in attitudes towards nutrition therapy within first- and fourth-year medical students. Methods: Participants (n=128) completed a computer self-administered questionnaire assessing attitudes towards nutrition therapy. Results: Analysis of covariance revealed that females report significantly more positive attitudes toward nutrition than males do, controlling for age. The magnitude of the difference was the same in beginning and graduating medical students. Conclusions: Gender differences in attitudes towards nutrition are not moderated by medical school socialization. Standardized nutrition education may be required to address disparities in knowledge, attitudes, and efficacy with regard to nutrition and preventive care measures.
