Discovering the Roots: A Qualitative Analysis of Medical Students Exploring Their Unconscious Obesity Bias

A Multi-Modality Intervention Improves Obesity Bias among Medical Students

Background: Obesity is linked to chronic diseases in adults and children. Its prevalence continues to grow in the United States, necessitating the need for healthcare provider training and presenting an opportunity for the education of future medical providers. Despite this need, effectively implementing obesity education into medical school curricula has been challenging. Anti-obesity bias amongst healthcare providers and trainees represents a significant obstacle to the care of patients with obesity. Obesity bias may affect up to 1/3 of medical students. Methods: This study describes the development and preliminary testing of a brief, 2.5 h multi-modality teaching intervention consisting of online, interactive, and independent learning modules for first-year medical students and a patient panel focused on obesity, obesity bias, and motivational interviewing. The participants took Crandall's anti-fat attitude (AFA) questionnaire before and after an online independent learning module on motivational interviewing and obesity bias. The AFA consists of three subscales ("dislike", "fear of fat", and "willpower"). Individual responses were measured using a nine-point Likert-type response format (0 = very strongly disagree; 9 = very strongly agree). An average composite score was calculated for each subscale. Results: Data were analyzed from 103 first-year medical students enrolled at a college of medicine in the southwestern United States in 2022. The AFA mean composite scores decreased significantly, indicating a decrease in explicit anti-obesity attitude bias after completing the online module. This decrease was present in all three domains of fear (4.63 vs. 3.72, p < 0.001), dislike (1.25 vs. 0.88, p < 0.001) and willpower (3.23 vs. 2.31, p < 0.001). Conclusions: Relatively brief educational interventions can positively impact students' anti-obesity attitudes.
