Assessing the Impact of Nutrition Training Among Medical Students

Introduction: Nutrition education remains inadequate in American medical schools, and physicians often cite lack of nutrition knowledge as a barrier to counseling patients. The goal of this study was to evaluate the impact of additional nutrition curriculum on first-year medical students.

Methods: We created a 1-hour nutrition lecture, delivered to first-year medical students. Using pre-, post-, and 3-month follow-up surveys, we assessed the following: (1) change in student knowledge; (2) confidence in counseling patients; (3) motivation to change their personal dietary behaviors; and (4) satisfaction with the curriculum. We assessed objectives using multiple choice questions and 10-point Likert scale questions.

Results: Of the 142 students who attended the live lecture, 105 (73.9%) completed both pre- and postsurveys, and 65 (45.8%) completed the 3-month follow-up survey. Students' knowledge of the material increased from 37% to 82%, but retention dropped to 65% at the 3-month mark (<.001). Comfort in assessing and counseling patients improved across the three survey iterations, from 3.53 to 5.90 to 8.00 (<.001). Motivation to change personal behaviors was high overall at 8.04, 8.36 and 8.25 [<.05]). Moreover, students were satisfied with the lecture, with a rating of 8.58/10.

Conclusions: This study supports the value of additional medical student nutrition education. This curriculum significantly increases student knowledge, comfort with the material, and confidence in counseling their future patients. A longitudinal curriculum that reinforces concepts over time will help improve long-term retention.
