Medical schools rely on body donation programs to obtain cadavers for teaching anatomy and conducting scientific research. However, many body donation programs utilize strict criteria for donation, including height, amputee status, body weight, or body mass index (BMI). BMI criteria limit medical students’ the familiarity and positive interactions with larger bodies, possibly decreasing the future quality of care provided by these students to high weight individuals and increasing weight stigma. This study assessed online criteria for 128 body donation programs in the United States, focusing on weight and BMI. Most (90.6%) of body donation program websites had weight-based restrictions, using either qualitative terms (79.7%, obese, proportional), quantitative measures (35.9%, BMI, weight), or both (25%). Only 9% provided justifications for weight limitations. In addition, no programs had DEI statements. The most used BMI cutoff (30 kg/m2) eliminates half of potential US body donors, since the average BMI for adults is 29.8 for females and 29.4 for males. This research demonstrates a key area for improvements in medical school weight bias. Increasing weight equity in body donation programs can be the first step in reducing medical weight bias and providing a broader and more realistic medical education with respect to body size.
