A Scoping Review of Physical Activity Interventions Among Sexual Minority Adults: A Call to Action for Future Research

Physical activity (PA) has a variety of well-established benefits for physical and mental health. However, there are PA disparities based on numerous sociodemographic characteristics, including sexual orientation. Mapping of PA interventions tailored to sexual minorities (ie, nonheterosexual) is currently absent from the literature. Purpose: The purpose of this scoping review was to summarize the existing interventions focused on promoting PA among sexual minority (SM) adults. Methods: A search strategy was developed in consultation with a research librarian for PubMed, Web of Science, SportDiscus, and CINAHL. The scoping review was conducted using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews guidelines. Randomized and nonrandomized interventions that focused on increasing PA among SM adults were included. Data on study design, sample demographics, purpose of research, methodology, intervention components, theory-based constructs used, PA measures, and outcomes of the intervention were extracted. Results: Our search yielded 7289 articles, with 26 articles requiring full-text review. Four interventions were identified that focused on increasing PA among SM adults, with 2 focusing on lesbian/bisexual women, 1 focusing on lesbian/gay cancer survivors, and 1 focusing on men who have sex with men. Two of the 4 studies were successful at increasing PA, with varying psychosocial theories (ie, social cognitive theory and theory of reasoned action) and intervention strategies (ie, PA counseling, group meetings, and pedometers). Conclusion: Findings of this review demonstrate a clear lack of PA interventions targeting SM adults, limiting the available knowledge required for preventionists, practitioners, and health care professionals to effectively promote PA through behavioral modification among this group.
