This study aims to measure the association between body mass index (BMI), comparing two different classifications, and mortality among community-dwelling elderly considering myopenia in Pelotas, Brazil. This is a longitudinal study started in 2014, we followed 1451 elderly people (≥ 60 years) enrolled in the "COMO VAI?" study. BMI was classified according to the World Health Organization (WHO) and the classification with specific cutoff points for older adults.

The purpose of this study was to asses the association between multimorbidities and handgrip strength in older community-dwelling individuals from a city in southern Brazil, identifying potential differences according to sex and loss of muscle mass.
Methods: This was a cross-sectional population-based study among older individuals living in the urban area of Pelotas, Rio Grande do Sul, Brazil.
Sarcopenia as a mortality predictor in community-dwelling older adults: a comparison of the diagnostic criteria of the European Working Group on Sarcopenia in Older People.

Background/objectives: The definition of sarcopenia remains a matter of discussion and there is no globally accepted consensus for its diagnosis. The aim of this study was to assess the effect of sarcopenia diagnostic components on mortality, as well as to compare the associations between sarcopenia diagnosed via the 2010 and 2018 Consensuses of the European Working Group on Sarcopenia in Older People (EWGSOP) and mortality.
Methods: Prospective cohort study involving noninstitutionalized older adults aged ≥ 60 years.
Objectives: To validate the (Brazilian) Portuguese-translated version of the SARC-F questionnaire and to verify its performance in the separate sarcopenia screening and muscle function evaluation contexts. In addition, by associating SARC-F to an anthropometric measurement (as an estimate of muscle mass), to test for improvements in its sarcopenia screening efficacy.
Design: Cross-sectional study.
Objective: This study aimed to develop and validate equations to estimate body fat based on anthropometric measurements of subcutaneous fat thickness (SFT) and muscle thickness (MT) measured by A-mode ultrasound (BodyMetrix) in Brazilian adults.
Methods: Individuals (n = 206) underwent air-displacement plethysmography for body composition assessment. Arm, thigh, and calf circumferences were also obtained.
Background & Aims: Lean mass (LM) is an important parameter in clinical outcomes, which highlights the necessity of reliable tools for its estimation. The adductor pollicis muscle thickness (APMT) is easily accessible and suffers minimal interference from the adjacent subcutaneous fat tissue.
Objective: To assess the relationship between the APMT and LM in a sample of Southern Brazilian adults.
Background & Aims: Body composition is important to identify malnutrition, and several anthropometric measurements are used to estimate muscle mass in the clinical practice. This study aimed to assess the adductor pollicis muscle thickness (APMT), its covariates and association with malnutrition in hospitalized surgical patients.
Methods: APMT was measured in 361 surgical patients in both dominant (DAPMT) and non-dominant (NDAPMT) sides.
