Body mass index and mortality in the elderly.

Bioelectrical impedance vector analysis, phase-angle assessment and relationship with malnutrition risk in a cohort of frail older hospital patients in the United Kingdom

“…Although beyond the scope of this article, this possible discordance may be a serious clinical issue as frail comorbid older patients at high nutritional risk may go unreported, since the MUST is the current gold standard for assessing malnutrition risk in the United Kingdom. Data from this study also supports the notion of possible increased malnutrition risk despite being within normal BMI ranges (BMI paradox in older people) [29].…”

“…These possible alterations may be consistent here (e.g., note the normal-high BMI range of patients, especially women [ Table 1] and the shortening of the R/H component). These complicated body composition alterations in frailty also may be a basis behind the potential BMI paradox in groups of older adults [29]. There are still many aspects that require further investigation with regard to BIVA accuracy, and it is known that potentially more accurate methods including specific BIVA are currently being developed [17].…”

Análise crítica do uso do índice de massa corporal para idosos

“…Vários pesquisadores têm sugerido a utilização do IMC em estudos para investigar a relação entre sobrepeso e baixo peso com o risco de mortalidade 8,[45][46][47][48][49][50][51] . Embora o IMC não possibilite determinar a composição corporal e não expresse a distribuição de gordura, é importante na determinação do risco de muitas doenças.…”

Nutritivni status kod starih osoba

“…Prеvаlеncа gојаznоsti neprekidno raste i prеdstаvljа znаčајаn zdrаvstvеni prоblеm u vеćini zеmаljа [30].

“…Ovakvo stanje uhranjenosti nosi u sebi energetsku rezervu i može biti korisno u slučајеvimа pоrаstа mеtаbоličkih pоtrеbа, kао štо su оbоljеnje, trаuma, imobilizаciја ili оpеrаtivnе intеrvеnciје. Finski аutоri nаšli su nеgаtivnu kоrеlаciјu izmеđu indeksa tjelesne mase i mоrtаlitеtа kоd оsоbа stаriјih оd 85 gоdinа, pri čеmu је nајmаnjа stоpа mоrtаlitеtа u tоku prаćеnjа pet godina bilа u grupi stаrih osoba čiјi је indeks tjelesne mase 30 kg/m 2 [30].…”
