We excluded children with a gestational age &amp;lt;37 weeks, intrauterine growth restriction, acute illness, or preexisting complex chronic conditions. Average daily in-hospital weight gain was categorized as (1) below average or (2) average or greater for age. \u03c72, Fisher\u2019s exact test, and 1-way analysis of variance tests were used to compare patient demographics, therapies, and FTT etiologies with categorical weight gain; multivariable logistic regression models tested for associations.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS:<\/jats:title><jats:p>There were 331 children included. The primary etiologies of FTT were neglect (30.5%), gastroesophageal reflux disease (GERD) (28.1%), child-centered feeding difficulties (22.4%), and organic pathology (19.0%). Average or greater weight gain for age had a specificity of 22.2% and positive predictive value of 33.9% for differentiating neglect from other FTT etiologies. However, sensitivity and negative predictive value were 91.1% and 85.0%, respectively. After adjusting for demographics and therapies received, neglect (P = .02) and child-centered feeding difficulties (P = .01) were more likely to have average or greater weight gain for age compared with organic pathology. Children with GERD gained similarly (P = .11) to children with organic pathology.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS:<\/jats:title><jats:p>In-hospital weight gain was nonspecific for differentiating neglect from other FTT etiologies. Clinicians should exercise caution when using weight gain alone to confirm neglect. Conversely, below average weight gain may be more useful in supporting GERD or organic pathologies but cannot fully rule out neglect.<\/jats:p><\/jats:sec>","DOI":"10.1542\/hpeds.2018-0035","type":"journal-article","created":{"date-parts":[[2018,10,1]],"date-time":"2018-10-01T08:25:30Z","timestamp":1538382330000},"page":"620-627","source":"Crossref","is-referenced-by-count":11,"title":["The
