Prevalence of Sarcopenia Based on Different Diagnostic Criteria Using DEXA and Appendicular Skeletal Muscle Mass Reference Values in an Italian Population Aged 20 to 80

Indicators of sarcopenia and their relation to intrinsic and extrinsic factors relating to falls among active elderly women

“…However, when assessed using a more precise method (DXA), the muscle mass values were below the recommended level for their age group, 11,14 despite the fact that neither their musculoskeletal function nor their physical performance were affected. 14,15,26 This highlights the importance of conducting more accurate assessments in order to prevent sarcopenia.…”

“…This method can quantify fat content, muscle mass and body bone mass more accurately, especially among the elderly population. 9,11 The correlation between sarcopenia and balance in the elderly has previously been investigated. Studies have shown that muscle strength affects the static balance (feet together, tandem, semi-tandem, eyes open and eyes closed) and gait of elderly community-dwellers.…”

Pontos de corte alternativos para massa muscular apendicular para verificação da sarcopenia em idosos brasileiros: dados da Rede Fibra - Belo Horizonte/Brasil

“…Many studies have shown that the classification of sarcopenia is highly dependent on the method used to assess it, as well as on population specificity 7,8,10,11 . Our findings regarding the AAM values (<6.47kg/m² for women and <8.76kg/m² for men) are similar to those found by Alexandre et al 19 (<6.37kg/m² for women and <8.90kg/m² for men), who used data from the Sabe study (Saúde, Bem-Estar e Envelhecimento) 20 .…”

“…Many studies have been conducted comparing different diagnostic criteria for sarcopenia and the relationship between its prevalence and adverse outcomes. The results have shown low agreement, when the various methods are compared, and prevalence has been variable, according to the instrument and cut-off points used for evaluation of lean muscle mass [9][10][11][12] . Due to the lack of reference values for the older Brazilian population, the need to better classify and understand the specificities of sarcopenia, in addition to its clinical and functional outcomes for this population and the high cost of the imaging resources used to estimate muscle mass, the objective of this study was to suggest alternative cut-off points for the calculation of appendicular lean mass (ALM), using a predictive equation that can be easily employed in clinical practice for early detection of loss of lean body mass and diagnosis of sarcopenia, in addition to establishing possible correlations between this syndrome and functional capacity and comorbidities in Brazilian older adults.…”

Sessão de Tai Chi Chuan promove hipotensão pós-exercício e redução da sobrecarga cardiovascular em idosos hipertensos

“…Essas mudanças relacionadas à idade afetam diversos tecidos e órgãos, o que compromete a realização das atividades da vida diária e qualidade de vida dos idosos. 2,3 O processo de envelhecimento é agravado com o sedentarismo, propiciando alterações na composição corporal como o aumento da gordura corporal, principalmente na região abdominal e a perda de massa muscular. Esses fatores aumentam o risco de desenvolvimento de doenças metabólicas e cardiovasculares tais como, a obesidade, diabetes tipo 2, doença arterial coronariana, dislipidemia e hipertensão arterial sistêmica (HAS), aumentando a chance de morte dessas pessoas.…”
