The secondary aim was to develop a new SFT-based body fat equation (SFTNICKERSON). SFT-based %Fat was estimated using a body fat equation from Gonz\u00e1lez-Ag\u00fcero (SFTG-A) and body density conversion formulas from Siri (SFTSIRI) and Brozek (SFTBROZEK). Criterion %Fat was measured via DXA. SFTG-A, SFTSIRI, and SFTBROZEK were significantly lower than DXA (mean differences ranged from \u22127.59 to \u221213.51%; all p &lt; 0.001). The SEE values ranged from 3.47% (SFTBROZEK) to 8.60% (SFTG-A). The 95% limits of agreement were greater than \u00b110% for all comparisons. Mid-axilla and suprailium were significant predictors of %Fat (both p &lt; 0.05). %Fat SFTNICKERSON = 10.323 + (0.661 \u00d7 mid-axilla) + (0.712 \u00d7 suprailium). Age and all other skinfold sites were not statically significant in the regression model (all p &gt; 0.05). Current findings indicate that SFTG-A, SFTSIRI, and SFTBROZEK erroneously place an individual with excessive adiposity in a normal healthy range. Accordingly, the current study developed a new equation (SFTNICKERSON) that can easily be administered in people with DS in a quick and efficient time frame. However, further research is warranted in this area.<\/jats:p>","DOI":"10.3390\/ijerph20105831","type":"journal-article","created":{"date-parts":[[2023,5,16]],"date-time":"2023-05-16T02:27:04Z","timestamp":1684204024000},"page":"5831","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Evaluation of Skinfold Techniques in People with Down Syndrome: Development of a New Equation"],"prefix":"10.3390","volume":"20","author":[{"given":"Brett S.","family":"Nickerson","sequence":"first","affiliation":[{"name":"School of Health and Rehabilitation Science, The Ohio State University, Columbus, OH 43210, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael R.","family":"Esco","sequence":"additional","affiliation":[{"name":"Department of Kinesiology, The University of Alabama, Tuscaloosa, AL 35487, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"George","family":"Schaefer","sequence":"additional","affiliation":[{"name":"Department of Kinesiology, Auburn University at Montgomery, Montgomery, AL 36117, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1461","DOI":"10.1016\/j.apmr.2004.10.038","article-title":"Obesity prevalence among a group of Chicago residents with disabilities","volume":"86","author":"Rimmer","year":"2005","journal-title":"Arch.
