Purpose: Weight stigma is associated with poor mental and emotional health and may be especially harmful to sexual and gender minority (SGM) individuals due to co-occurring minority stress. The literature on this topic has not been synthesized. We conducted a scoping review of the literature on weight stigma and mental and emotional health among SGM individuals to synthesize findings, highlight gaps, and identify clinical and research implications. Methods: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews, we searched PubMed, CINAHL, PsycINFO, and Scopus in April 2022. Included studies examined the relationship between weight stigma and mental and emotional health among SGM people of any age. We did not restrict study design or publication date. Results: Of 513 records identified, 23 met inclusion criteria. Most focused on sexual minority individuals; one focused specifically on gender minority individuals. Weight stigma was associated with poorer mental and emotional health in nearly all studies. The most common outcomes examined were self-esteem, maladaptive eating, and depressive symptoms. Five studies, all using the same dataset, focused on adolescents; none focused on older adults. Conclusions: Weight stigma is associated with poorer mental and emotional health among SGM individuals and, through its intersections with minority stress, might impact SGM individuals differently than their cisgender and heterosexual counterparts. There are important gaps regarding weight stigma's effect on SGM adolescents and gender minority individuals and its relationship with a broader range of mental and emotional health outcomes.
