Our aim was to assess the prevalence of malnutrition, to compare anthropometric parameters in the evaluation of nutritional status in pediatric IBD, and to investigate the association between anthropometric parameters and disease activity indices (AI). Pediatric patients with newly diagnosed IBD recorded between 2010 and 2016 in the Hungarian Pediatric IBD Registry were included in this cross-sectional study. Body weight, body mass index (BMI), weight-for-height, and ideal body weight percent (IBW%) were analyzed. Pearson linear and non-linear correlations and polynomial regression analyses were performed to assess correlation between nutritional status and AI. p-values &lt; 0.05 were considered significant. Anthropometric data of 1027 children with IBD (Crohn\u2019s disease (CD): 699; ulcerative colitis (UC): 328; mean age 13.7 years) were analyzed. IBW% identified more obese patients than BMI both in CD (7.02% vs. 2.28%) and UC (12.17% vs. 5.48%). Significant negative correlation was found among anthropometric parameters and AI in CD. In contrast, polynomial regression analysis revealed a U-shaped correlation curve between IBW% and AI in UC. Our findings show that obesity has a bimodal association with disease activity in pediatric UC. Furthermore, IBW% was more useful to identify obese pediatric patients with IBD.<\/jats:p>","DOI":"10.3390\/ijerph192316091","type":"journal-article","created":{"date-parts":[[2022,12,2]],"date-time":"2022-12-02T01:44:46Z","timestamp":1669945486000},"page":"16091","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Disease Activity Is Associated with Obesity in Newly Diagnosed Pediatric Patients with Ulcerative Colitis"],"prefix":"10.3390","volume":"19","author":[{"given":"Orsolya","family":"Kadenczki","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Faculty of Medicine, University of Debrecen, 4032 Debrecen, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antal","family":"Dezsofi","sequence":"additional","affiliation":[{"name":"1st Department of Pediatrics, Semmelweis University, 1083 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aron","family":"Cseh","sequence":"additional","affiliation":[{"name":"1st Department of Pediatrics, Semmelweis University, 1083 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Szucs","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, University of Szeged, 6725 Szeged, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noemi","family":"Vass","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, University of Szeged, 6725 Szeged, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eva","family":"Nemes","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Faculty of Medicine, University of Debrecen, 4032 Debrecen, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7019-2755","authenticated-orcid":false,"given":"Andras","family":"Tarnok","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Medical School, University of P\u00e9cs, 7623 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erzsebet","family":"Szakos","sequence":"additional","affiliation":[{"name":"Borsod Aba\u00faj Zempl\u00e9n County University Teaching Hospital, University of Miskolc, 3526 Miskolc, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ildiko","family":"Guthy","sequence":"additional","affiliation":[{"name":"Szabolcs-Szatm\u00e1r-Bereg County Hospitals, University Teaching Hospital, 4400 Ny\u00edregyh\u00e1za, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marta","family":"Kovacs","sequence":"additional","affiliation":[{"name":"Petz Aladar Teaching Hospital, 9024 Gy\u0151r, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Karoliny","sequence":"additional","affiliation":[{"name":"Heim Pal National Pediatric Institute, 1089 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Judit","family":"Czelecz","sequence":"additional","affiliation":[{"name":"Bethesda Children\u2019s Hospital, 1146 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5170-5965","authenticated-orcid":false,"given":"Csongor","family":"Kiss","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Faculty of Medicine, University of Debrecen, 4032 Debrecen, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5355-4224","authenticated-orcid":false,"given":"Katalin Eszter","family":"M\u00fcller","sequence":"additional","affiliation":[{"name":"Heim Pal National Pediatric Institute, 1089 Budapest, Hungary"},{"name":"Institute of Translation Medicine, Medical School, University of P\u00e9cs, 7623 P\u00e9cs, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2769","DOI":"10.1016\/S0140-6736(17)32448-0","article-title":"Worldwide incidence and prevalence of inflammatory bowel disease in the 21st century: A systematic review of population-based studies","volume":"390","author":"Ng","year":"2017","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1093","DOI":"10.1016\/S0140-6736(00)04309-9","article-title":"Prospective survey of childhood inflammatory bowel disease in the British Isles","volume":"357","author":"Sawczenko","year":"2001","journal-title":"Lancet"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"1105","DOI":"10.1002\/ibd.20429","article-title":"Nationwide prevalence and prognostic significance of clinically diagnosable protein-calorie malnutrition in hospitalized inflammatory bowel disease patients","volume":"14","author":"Nguyen","year":"2008","journal-title":"Inflamm.
