Women and TGE individuals attempted to lose weight more often than men, while men attempted to gain weight more often. All genders endorsed weight loss and gain attempts for different purposes. Weight loss attempts related to ED symptoms and appearance intolerance, whereas weight gain attempts related to MD symptoms across genders. In women, all weight change attempts related to greater functional impairment due to exercise. Findings highlight the need for tailored interventions to address desires to change one's body and underscore the harmful effects of weight change attempts across genders.","PeriodicalId":48835,"journal":{"name":"Eating Disorders","volume":" ","pages":"537-553"},"PeriodicalIF":3.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142074272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper aims to update the original synthesis and to situate participant responses to the category of \"T-AN\". Thus, extending the proposed conceptualization of the SE-AN experience. A systematic search identified published scholarship (between August 2022 and July 2023), derived from five bibliographic databases. A comprehensive methodology combining Interpretative Phenomenological Analysis and a meta-ethnographic framework enabled the synthesis of meta-themes across 9 new studies. These meta-themes were mapped onto the primary synthesis to further develop upon the earlier LE conceptualization of SE-AN. Nine extracted papers expanded the voices to 447 people within 45 studies. All papers affirmed and enriched the previous themes, and a novel theme was generated from the recent papers. The new theme, \"walking on a knife's edge, caught between worlds\", informed an expanded conceptualization of SE-AN, termed the Web of Hope. Thus, demonstrating how participants held onto hope in the face of the SE-AN experience. Death, dying and \"terminality\", were notably absent in the 36 papers in the previous meta-synthesis. Since the proposal of the category of \"terminal anorexia\" in 2022, studies on the lived experience of SE-AN increasingly focused on how people hold onto hope alongside SE-AN.

We also explore the limitations of ROC analysis and show that the analogous logistic regression models outperform their ROC counterparts. Participants (N = 233) were patients with AN who received virtual outpatient FBT. ROC analyses used early weight gain to predict remission in week 20. Weight gain at week 8 performed best (AUC = 0.65 [0.58-0.72]). The optimal cutpoint was 8.9 pounds; 36% of the patients were misclassified. A regression model, which included percent target weight at admission in addition to early weight gain as a predictor variable, outperformed the ROC and returned the probability that a patient will remit. These data suggest that using early weight gain alone to set cutpoints misclassifies many patients with AN.
