Some of the literature indicates insufficient evidence to affirm the impact of dietetic interventions, emphasising variability in outcomes and a need for standardised research. This study aimed to identify the clinical characteristics of adolescents requiring dietetic intervention during FT-AN and to assess differences in clinical outcomes between those receiving dietetic support and those who did not. Methods: A retrospective cohort study was conducted at the Maudsley Centre for Child and Adolescent Eating Disorders in London. Patients were selected from electronic records. Inclusion criteria were ICD-10 diagnosis of AN and completion of FT-AN treatment between January 2020 and December 2022. Collected data included weight (kg and %mBMI), eating disorder symptom severity, pre-assessment anxiety (patient and parent), and details of FT-AN sessions (i.e., frequency and amount). The sample was divided into two groups: those who received dietetic input and those who did not. Statistical analyses included Mann\u2013Whitney U tests, \u03c72 tests, independent t-tests, and a logistic regression to examine differences at baseline, 4\u20136 weeks post-assessment, and discharge. Results: The study included 92 participants (dietetic group = 33 participants; non-dietetic group = 59 participants). Baseline characteristics were comparable between groups. The logistic regression showed no significant predictors for dietetic input. At 4\u20136 weeks, those requiring dietetic input exhibited lower %mBMI (83.3% vs. 87.3%, p = 0.027) and poorer weight gain (+2.3 kg vs. +3.1 kg, p = 0.04). By discharge, weight restoration was similar (92% vs. 93% mBMI, p = 0.64), although the dietetic group had more therapeutic treatment sessions (24 vs. 19, p = 0.04). Discussion: This study found no specific predictors for prioritising dietetic input in young people during FT-AN treatment. While those receiving dietetic support struggled with weight gain early and attended more sessions, both groups achieved similar weight outcomes by the end of treatment. Future research should focus on the timing and content of dietetic interventions, as well as perspectives from patients and caregivers, to better understand their role and impact on cognitive and emotional recovery aspects.<\/jats:p>","DOI":"10.3390\/nu16234117","type":"journal-article","created":{"date-parts":[[2024,11,28]],"date-time":"2024-11-28T10:19:42Z","timestamp":1732789182000},"page":"4117","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["An Exploration of Clinical Characteristics and Treatment Outcomes Associated with Dietetic Intervention in Adolescent Anorexia Nervosa"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0041-5196","authenticated-orcid":false,"given":"Cliona","family":"Brennan","sequence":"first","affiliation":[{"name":"Maudsley Centre for Child and Adolescent Eating Disorders, South London and Maudsley NHS Foundation Trust, De Crespigny Park, Denmark Hill, London SE5 8AZ, UK"},{"name":"Department of Human Nutrition and Dietetics, School of Health Sciences, London Metropolitan University, 166-220 Holloway Road, London N7 8DB, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lara","family":"Felemban","sequence":"additional","affiliation":[{"name":"King\u2019s College London, 150 Stamford Street, London SE1 9NH, UK"},{"name":"Department of Nutrition and Dietetics, North Middlesex University Hospital NHS Trust, Sterling Way, London N18 1QX, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ellen","family":"McAdams","sequence":"additional","affiliation":[{"name":"Maudsley Centre for Child and Adolescent Eating Disorders, South London and Maudsley NHS Foundation Trust, De Crespigny Park, Denmark Hill, London SE5 8AZ, UK"},{"name":"Institute of Psychiatry, Psychology and Neuroscience, King\u2019s College London, De Crespigny Park, London SE5 8AZ, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7943-0502","authenticated-orcid":false,"given":"Kevin","family":"Walsh","sequence":"additional","affiliation":[{"name":"King\u2019s College London, 150 Stamford Street, London SE1 9NH, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7840-4158","authenticated-orcid":false,"given":"Julian","family":"Baudinet","sequence":"additional","affiliation":[{"name":"Maudsley Centre for Child and Adolescent Eating Disorders, South London and Maudsley NHS Foundation Trust, De Crespigny Park, Denmark Hill, London SE5 8AZ, UK"},{"name":"Institute of Psychiatry, Psychology and Neuroscience, King\u2019s College London, De Crespigny Park, London SE5 8AZ, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"American Psychiatric Association (2022).
