Anorexia Nervosa is characterised by significant disruptions in weight, growth and physical health resulting from disordered behaviours such as food restriction, purging and inappropriate exercise. The illness is associated with substantial physical, psychological, social and economic burdens affecting all areas of functioning. Typically emerging in adolescence, AN can have a chronic course and high risk of mortality, with evidence suggesting that approximately 10% of individuals diagnosed with AN will die from medical complications or completed suicide. Whilst inpatient treatment reduces mortality risks through nutritional and weight restoration, outpatient treatment is the preferred level of intervention. In the case of adolescents, family-based treatment (FBT) is the recommended and most researched outpatient model for medically stable adolescents. However, access to FBT is limited, and there are several barriers that exist to receiving care from trained clinicians. This review provides a literature update on studies reporting the real-world access challenges for FBT, with particular attention paid to non-research settings. The review also highlights how digitally delivered treatment, specifically telehealth, has been used to increase access to FBT and examines the preliminary outcomes of telehealth-delivered FBT, which appear comparable to traditional in-person care. Despite these promising findings, provider, intervention and systemic factors have challenged the delivery of traditional in-person and telehealth FBT in real-world settings. Critical areas for future research include the need to understand the impact of potential confounders and what adaptions may be required to increase model feasibility in community settings, where access to specialist services is often limited and access challenges are most felt.<\/jats:p>","DOI":"10.3390\/nu17132160","type":"journal-article","created":{"date-parts":[[2025,6,30]],"date-time":"2025-06-30T06:18:36Z","timestamp":1751264316000},"page":"2160","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Advancements in Family-Based Treatment of Adolescent Anorexia Nervosa: A Review of Access Barriers and Telehealth Solutions"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6912-0911","authenticated-orcid":false,"given":"Ashlea","family":"Hambleton","sequence":"first","affiliation":[{"name":"InsideOut Institute, University of Sydney, Sydney Local Health District, Sydney, NSW 2000, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7293-9496","authenticated-orcid":false,"given":"Daniel","family":"Le Grange","sequence":"additional","affiliation":[{"name":"UCSF Weill Institute for Neurosciences, University of California San Francisco, San Francisco, CA 94107, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen","family":"Touyz","sequence":"additional","affiliation":[{"name":"InsideOut Institute, University of Sydney, Sydney Local Health District, Sydney, NSW 2000, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0754-9189","authenticated-orcid":false,"given":"Sarah","family":"Maguire","sequence":"additional","affiliation":[{"name":"InsideOut Institute, University of Sydney, Sydney Local Health District, Sydney, NSW 2000, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"205","DOI":"10.12740\/PP\/64580","article-title":"Outcome, comorbidity and prognosis in anorexia nervosa","volume":"51","author":"Jagielska","year":"2017","journal-title":"Psychiatr.
