We performed a case-control study on 287 children aged between 3 to 18 years, admitted in a Romanian Pediatric Tertiary Hospital, which we divided according to the body mass index (BMI) into two groups: the study group-77 children with obesity, and control group-210 children with normal weight. All children underwent anamnesis, clinical exam, laboratory parameters, ultrasound exam, and elastography. Children with obesity presented higher values of platelets, AST, ALT, and AAR as compared to control group (p\u2009=\u20090.0005\/p\u2009=\u20090.0065\/p\u2009&lt;\u20090.0001\/p\u2009&lt;\u20090.0001). We found no significant differences for APRI between the two groups (p\u2009=\u20090.9827), although the values were higher in children with obesity. Significantly higher values of liver stiffness in children with obesity on both 2D-SWE and TE (p\u2009=\u20090.0314\/p\u2009&lt;\u20090.0001) were obtained. Similarly, the velocity values measured by 2D-SWE were also significantly higher in the study group (p\u2009&lt;\u20090.0001). Our findings revealed significantly higher levels of platelets, transaminases, AAR, and liver stiffness values on both TE and 2D-SWE in children with obesity. 2D-SWE and TE might represent useful non-invasive methods for predicting liver impairment associated to pediatric obesity.<\/jats:p>","DOI":"10.1038\/s41598-019-56358-2","type":"journal-article","created":{"date-parts":[[2019,12,24]],"date-time":"2019-12-24T11:02:32Z","timestamp":1577185352000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["The assessment of liver fibrosis in children with obesity on two methods: transient and two dimensional shear wave elastography"],"prefix":"10.1038","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2119-1726","authenticated-orcid":false,"given":"Cristina Oana","family":"M\u0103rginean","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lorena Elena","family":"Meli\u0163","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dana Valentina","family":"Ghiga","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Oana","family":"S\u0103s\u0103ran","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2019,12,24]]},"reference":[{"key":"56358_CR1","unstructured":"WHO | Overweight and obesity, https:\/\/www.who.int\/gho\/ncd\/risk_factors\/overweight\/en\/."},{"key":"56358_CR2","doi-asserted-by":"publisher","first-page":"271","DOI":"10.3389\/fped.2018.00271","volume":"6","author":"CO M\u01cerginean","year":"2018","unstructured":"M\u01cerginean, C.
