Community\u2010dwelling older adults aged \u226560\u2009years were assessed for body composition and functional measures between November 2012 and July 2017 in the geriatric outpatient clinic of a university hospital. Body composition was assessed with bioimpedance analysis. Skeletal muscle mass (SMM) was adjusted by height<jats:sup>2<\/jats:sup>, weight or body mass index (BMI). Functional and disability measures included handgrip strength assessed by a Jamar hydraulic hand dynamometer, gait speed by 4\u2010m usual gait speed, frailty by the Fatigue, Resistance, Ambulation, Illnesses and Loss of Weight scale score, activities of daily living (ADL) and instrumental ADL scores. Nutrition was evaluated by the Mini Nutritional Assessment \u2013 Short Form.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 1437 older adults (458 men, 979 women) with a mean age of 74.6\u2009\u00b1\u20097.0\u2009years were included. The prevalences of low muscle mass were 2.4%, 47.8% and 20.3% when SMM was adjusted by height<jats:sup>2<\/jats:sup>, weight and BMI, respectively. Multivariate analyses adjusted for age, number of diseases, drugs and the Mini Nutritional Assessment \u2013 Short Form score revealed that when the SMM was adjusted by BMI, low muscle mass showed better associations with grip strength, gait speed, ADL, instrumental ADL and frailty than the height<jats:sup>2<\/jats:sup> or the weight\u2010adjusted SMM.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>SMM adjustment by BMI to designate low muscle mass was better associated with functional and disability measures than adjustment by height<jats:sup>2<\/jats:sup> and weight. The present results put forward the SMM index (by BMI) as the best adjustment method for SMM. These findings might be relevant for defining both sarcopenia and malnutrition. <jats:bold>Geriatr Gerontol Int 2019; 19: 593\u2013597<\/jats:bold>.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ggi.13668","type":"journal-article","created":{"date-parts":[[2019,4,22]],"date-time":"2019-04-22T06:50:43Z","timestamp":1555915843000},"page":"593-597","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":56,"title":["Association of different bioimpedanciometry estimations of muscle mass with functional measures"],"prefix":"10.1111","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5343-9795","authenticated-orcid":false,"given":"Gulistan","family":"Bahat","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Division of Geriatrics Istanbul Medical School, Istanbul University  Istanbul Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cihan","family":"Kilic","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Division of Geriatrics Istanbul Medical School, Istanbul University  Istanbul Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Birkan","family":"Ilhan","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Division of Geriatrics Istanbul Medical School, Istanbul University  Istanbul Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mehmet A","family":"Karan","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Division of Geriatrics Istanbul Medical School, Istanbul University  Istanbul Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alfonso","family":"Cruz\u2010Jentoft","sequence":"additional","affiliation":[{"name":"Division of Geriatrics University of Ramon y Cajal  Madrid Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,4,21]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/ageing\/afq034"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clnu.2009.12.004"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jamda.2011.01.003"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jamda.2011.04.014"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1093\/gerona\/glu013"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clnu.2015.03.001"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clnu.2018.08.002"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1093\/oxfordjournals.aje.a009520"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1532-5415.2002.50216.x"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1093\/gerona\/glu023"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1093\/gerona\/glu012"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/jcsm.12130"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1532-5415.2003.51534.x"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1519\/JSC.0b013e31824f2040"},{"key":"e_1_2_6_16_1","first-page":"107","article-title":"Prediction of total body skeletal muscle mass from fat\u2010free mass or intra\u2010cellular water","volume":"2","author":"Deurenberg P","year":"2004","journal-title":"Int J Body Compos Res"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clnu.2016.02.002"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/s40520-018-1042-6"},{"key":"e_1_2_6_19_1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.1963.03060120024016"},{"key":"e_1_2_6_20_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532-5415.2007.01590.x"},{"key":"e_1_2_6_21_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532-5415.1998.tb03800.x"},{"key":"e_1_2_6_22_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jamda.2007.11.005"},{"key":"e_1_2_6_23_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12603-012-0084-2"},{"key":"e_1_2_6_24_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0899-9007(98)00171-3"},{"key":"e_1_2_6_25_1","doi-asserted-by":"publisher","DOI":"10.1038\/srep19457"},{"key":"e_1_2_6_26_1","doi-asserted-by":"publisher","DOI":"10.1111\/ggi.12040"},{"key":"e_1_2_6_27_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1532-5415.2007.01436.x"},{"key":"e_1_2_6_28_1","doi-asserted-by":"publisher","DOI":"10.1111\/ggi.12227"},{"key":"e_1_2_6_29_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0007114513000366"},{"key":"e_1_2_6_30_1","doi-asserted-by":"publisher","DOI":"10.1111\/ggi.13075"},{"key":"e_1_2_6_31_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0172052"}],"container-title":["Geriatrics &amp;
