ObjectiveThe COVID‐19 pandemic initiated public health measures, impacting mental health and exacerbating disordered eating behaviours (DEB). This study aims to fill gaps in understanding DEB in the general population during the pandemic, emphasising gender dynamics and the experiences of gender and/or sexual minority (SGM) individuals.MethodA systematic literature review followed PRISMA guidelines to investigate DEB during the pandemic, focusing on gender‐sensitive analyses and SGM populations. Outcomes from the included studies were synthesised to identify patterns and associations related to DEB, particularly considering gender dynamics and SGM experiences.ResultsSignificant gender associations with DEB were observed, with women consistently exhibiting higher scores. SGM populations also showed elevated DEB symptoms. Longitudinal studies indicated changes in DEB over time, with some decreases observed among men.ConclusionsThe review underscores significant gender differences in DEB during the pandemic, with women exhibiting higher symptom levels. Lockdown measures had nuanced impacts on DEB, varying across studies. Various factors including pandemic‐related stressors influenced DEB. Consideration of these factors can inform tailored interventions for DEB in the general population. Overall, the review enhances our understanding of how gender intersects with the pandemic's impact on DEB, emphasising the need for diverse approaches to address these behaviours.
