Efficacy of interventions aimed at reducing explicit and implicit weight bias in healthcare students: A systematic review and meta‐analysis

Summary We conducted a systematic review and meta‐analysis to determine the efficacy of interventions aimed at reducing weight bias in healthcare students, and to explore factors that may impact intervention success. A systematic review and random‐effects meta‐analyses were conducted by including studies that examined the efficacy of weight bias reduction interventions for healthcare students. Of the 3463 journal articles and dissertations screened, 67 studies (within 64 records) met inclusion criteria, with 35 studies included in the meta‐analyses (explicit = 35, implicit [and explicit] = 10) and 32 studies included in the narrative synthesis (explicit = 34, implicit [and explicit] = 3). Weight bias interventions had a small but positive impact, g = −0.31 (95% CI = −0.43 to −0.19, p
