Transgender Nutrition Scoping Review (2020)
An evidence scoping review was conducted to determine availability of literature examining hormone therapy, health outcomes and the role of nutrition in transgender individuals. The research question for this scoping review was:
What is the extent, range and nature of literature examining the nutrition-related intermediate and long-term health outcomes in individuals who are transgender? Specific sub-topics examined include 1) dietary intake, 2) nutrition-related health disparities, 3) validity and reliability of nutrition assessment methods, and 4) the effects of nutrition interventions/exposures and 5) hormone therapy.
Target Population: Individuals who are transgender. No limits on age.
Assessment: Validity and reliability of nutrition assessment methods
Interventions: Nutrition interventions, hormone therapy
- Intermediate Outcomes: Dietary intake, anthropometrics, nutrition-related lab values
- Health Outcomes: (a) mortality, b) osteoporosis/osteopenia, c) diabetes, d) cardiovascular disease, e) hypertension, f) metabolic syndrome, g) overweight/obesity/underweight, i) eating disorders, j) food insecurity, k) quality of life, and l) alcohol abuse
Locations: All locations. No limits.
Search Dates: 1999 to December 2019
Study Designs: Controlled and non-controlled trials, cohort and cross-sectional studies, qualitative studies, systematic reviews and evidence-based practice guidelines.
Databases: Medline, Embase, PsycINFO, CINAHL, Web of Science, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Health Technology Assessment Database, Database of Abstracts of Reviews of Effects (DARE), WHO ICTRP and Clincaltrials.gov
Scoping Review Conclusion:
Transgender individuals have unique nutrition needs, which may vary according to the stage of social and medical transition. While the potential nutrition-related health outcomes of hormone therapy and the prevalence of nutrition-related health outcomes compared to the cisgender population have been reported throughout the literature, there is still a lack of research examining effective methods of implementing nutrition therapy for nutrition professionals working with transgender individuals. A greater base of primary research examining relevant nutrition topics in transgender individuals is needed before there will be sufficient literature to inform high-quality evidence-based clinical nutrition practice guidelines for transgender individuals.
