Through a series of 30 computer\u2010simulated datasets for 1100 individuals (1000 \u201chealthy\u201d and 100 \u201cED\u201d), the package's options for predictive models are evaluated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Simulation results highlight the potential for use in ED screening and treatment and guide users on modeling options.

Aggregated across simulation approaches, results further support optimal accuracy in identifying ED cases when using mean, most recent, or mean\u2009+\u2009most recent methods (mean ED case classification accuracy\u2009=\u20090.86) as compared to the use of a population\u2010based metric\u201485% of the 50th percentile BMI (mean classification accuracy\u2009=\u20090.61).<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>The introduction of TeenGrowth represents a first step towards setting reproducible, personalized predicted body weights for young people.<\/jats:p><\/jats:sec>","DOI":"10.1002\/eat.24372","type":"journal-article","created":{"date-parts":[[2025,1,6]],"date-time":"2025-01-06T11:28:38Z","timestamp":1736162918000},"page":"658-668","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["<scp>TeenGrowth<\/scp>: Individualized Estimations of Weight\u2010Related Risk and Recovery Metrics for Young People With Eating Disorders"],"prefix":"10.1002","volume":"58","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3193-2233","authenticated-orcid":false,"given":"Katherine","family":"Schaumberg","sequence":"first","affiliation":[{"name":"University of Wisconsin\u2014Madison, University of Texas at Austin  Madison Wisconsin USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,1,6]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.brat.2014.02.006"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11920\u2010018\u20100932\u20109"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1001\/archpsyc.63.3.305"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.2471\/BLT.07.043497"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/erv.2503"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.22717"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/ijpo.12889"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2019\u20102339"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1080\/10640266.2018.1499297"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.23519"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1038\/sj.ijo.0802076"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.biopsych.2006.03.040"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.24125"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40337\u2010017\u20100145\u20103"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.22221"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2011\u20101676"},{"key":"e_1_2_9_18_1","doi-asserted-by":"publisher","DOI":"10.1080\/10640266.2017.1388664"},{"issue":"3","key":"e_1_2_9_19_1","first-page":"172","article-title":"What Does Weight Have to Do With Atypical AN?
