We hypothesized that differences in EBW would be greatest at the extremes of height.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS:<\/jats:title><jats:p>EBW was determined for 12\u2009047 individual adolescents aged 12 to 19 years by the WFS and BMI methods by utilizing the same National Center for Health Statistics data sets. Absolute difference between the 2 methods for each individual was calculated and plotted against height by using a generalized additive model. The number of individuals whose weights were &amp;lt;75% EBW was determined by each method.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS:<\/jats:title><jats:p>For girls, EBW was 3.52 \u00b1 3.13% higher when using the WFS method compared with the BMI method. For boys, EBWWFS was 3.45 \u00b1 2.72% higher than EBWBMI. Among adolescent girls, 65% had EBWWFS higher than EBWBMI. By using the EBWWFS method as the gold standard, specificity of the EBWBMI method to detect those &amp;lt;75% EBW was 0.999, but sensitivity was only 0.329. Absolute differences in EBW were most pronounced at the extremes of height.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS:<\/jats:title><jats:p>The WFS and BMI methods are not equivalent in determining EBW in adolescents and are not interchangeable. EBWWFS was \u223c3.5% higher than EBWBMI. In adolescents with eating disorders, use of the BMI method will underestimate the degree of malnutrition compared with the WFS method. Which method better predicts meaningful clinical outcomes remains to be determined.<\/jats:p><\/jats:sec>","DOI":"10.1542\/peds.2012-0897","type":"journal-article","created":{"date-parts":[[2012,11,13]],"date-time":"2012-11-13T10:52:14Z","timestamp":1352803934000},"page":"e1607-e1613","source":"Crossref","is-referenced-by-count":13,"title":["Expected Body Weight in Adolescents: Comparison Between Weight-for-Stature and BMI Methods"],"prefix":"10.1542","volume":"130","author":[{"given":"Neville H.","family":"Golden","sequence":"first","affiliation":[{"name":"Divisions of Adolescent Medicine,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Yang","sequence":"additional","affiliation":[{"name":"Neonatal and Developmental Medicine, and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc S.","family":"Jacobson","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Nassau University Medical Center, East Meadow, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas N.","family":"Robinson","sequence":"additional","affiliation":[{"name":"General Pediatrics, Department of Pediatrics, and"},{"name":"Stanford Prevention Research Center, Department of Medicine, Stanford University School of Medicine, Stanford, California; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gary M.","family":"Shaw","sequence":"additional","affiliation":[{"name":"Neonatal and Developmental Medicine, and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"417","published-online":{"date-parts":[[2012,12,1]]},"reference":[{"issue":"2","key":"2021120823594750200_B1","doi-asserted-by":"crossref","first-page":"191","DOI":"10.1016\/S0022-3476(98)70426-3","article-title":"Use of the body mass index (BMI) as a measure of overweight in children and adolescents.","volume":"132","author":"Dietz","year":"1998","journal-title":"J Pediatr"},{"issue":"17","key":"2021120823594750200_B2","doi-asserted-by":"crossref","first-page":"2028","DOI":"10.1001\/jama.298.17.2028","article-title":"Cause-specific excess deaths associated with underweight, overweight, and obesity.","volume":"298","author":"Flegal","year":"2007","journal-title":"JAMA"},{"issue":"9608","key":"2021120823594750200_B3","doi-asserted-by":"crossref","first-page":"243","DOI":"10.1016\/S0140-6736(07)61690-0","article-title":"Maternal and child undernutrition: global and regional exposures and health consequences.","volume":"371","author":"Black","year":"2008","journal-title":"Lancet"},{"key":"2021120823594750200_B4","doi-asserted-by":"crossref","first-page":"2047S","DOI":"10.1093\/jn\/124.suppl_10.2047S","article-title":"The relationship between child anthropometry and mortality in developing countries: implications for policy, programs and future research.","volume":"124","author":"Pelletier","year":"1994","journal-title":"J Nutr"},{"issue":"13","key":"2021120823594750200_B5","doi-asserted-by":"crossref","first-page":"1549","DOI":"10.1001\/jama.295.13.1549","article-title":"Prevalence of overweight and obesity in the United States, 1999-2004.","volume":"295","author":"Ogden","year":"2006","journal-title":"JAMA"},{"issue":"6","key":"2021120823594750200_B6","doi-asserted-by":"crossref","first-page":"601","DOI":"10.1016\/j.jadohealth.2011.04.019","article-title":"Trends in body mass index in adolescence and young adulthood in the United States: 1959-2002.","volume":"49","author":"Lee","year":"2011","journal-title":"J Adolesc Health"},{"issue":"1","key":"2021120823594750200_B7","doi-asserted-by":"crossref","first-page":"11","DOI":"10.1080\/17477160600586747","article-title":"Worldwide trends in childhood overweight and obesity.","volume":"1","author":"Wang","year":"2006","journal-title":"Int J Pediatr Obes"},{"key":"2021120823594750200_B8"},{"key":"2021120823594750200_B9"},{"issue":"6","key":"2021120823594750200_B10","first-page":"496","article-title":"Eating disorders in adolescents: position paper of the Society for Adolescent Medicine.","volume":"33","author":"Golden","year":"2003","journal-title":"J Adolesc Health"},{"issue":"6","key":"2021120823594750200_B11","doi-asserted-by":"crossref","first-page":"1240","DOI":"10.1542\/peds.2010-2821","article-title":"Identification and management of eating disorders in children and adolescents.","volume":"126","author":"Rosen","year":"2010","journal-title":"Pediatrics"},{"issue":"3","key":"2021120823594750200_B12","article-title":"Obesity evaluation and treatment: Expert Committee recommendations.
