Abstract Objective: To evaluate muscle functionality, physical performance and body composition in young people living with human immunodeficiency virus (PLWH). Subjects and methods: Eighty-one HIV-infected and 54 uninfected (20 to 50 years) male and female subjects were enrolled to participate. Patient evaluation included body composition by DXA (dual energy X-rays), SARC-F questionnaire, hand grip and timed up & go (TUG) tests. Results: Fifty PLWH and 50 age-gender matched controls completed the study. The median age was 40 (25-49) vs. 36.5 […]

ABSTRACT The global increase in life expectancy has led to a concomitant rise in diagnoses of sarcopenia. At the same time, the epidemic levels of obesity have given rise to the emergence of a complex condition known as sarcopenic obesity. Characterized by the simultaneous presence of loss of muscle mass and strength along with obesity or excess body fat, sarcopenic obesity represents a concerning health condition. Contrary to prevailing assumptions, sarcopenic obesity is not exclusive to older adults, as it […]

ABSTRACT Objective: To identify the obesity diagnosis with the highest association with physical frailty associated with sarcopenia EWGSOP II (sarcopenic obesity). Subjects and methods: We performed a cross-sectional analysis of 371 community-dwelling older adults. Appendicular skeletal lean mass and total body fat (TBF) were assessed using dual-energy x-ray absorptiometry, and physical frailty was defined using Fried’s criteria. The phenotypes were identified according to the presence of sarcopenia by EWGSOP II and obesity, which was diagnosed using two concepts: BMI obesity […]

Abstract Obesity affects several areas of the human body, leading to increased morbidity and mortality and the likelihood of other diseases, such as type 2 diabetes mellitus, cardiovascular diseases and musculoskeletal disorders. These conditions predispose to bone fractures and sarcopenic obesity, defined by the presence of an obesity-associated decrease in muscle mass and strength. Both bone fragility and sarcopenic obesity disease are consequences of several factors, such as a low degree of chronic inflammation, insulin resistance, hormonal changes, nutritional deficiencies, […]

ABSTRACT Objective: Evaluating the prevalence of sarcopenia in women submitted to bariatric surgery – Roux-en-Y gastric bypass. Design: Observational, cross-sectional study. Subjects and methods: Women (18-65 years old) who underwent bariatric surgery (BG) ≥ 2 years and reached stable weight ≥ 6 months, were investigated. Control group (CG) comprised non-operated matched women with obesity. Body composition was determined through dual-energy X-ray absorptiometry. Low lean mass (LLM) was defined as appendicular lean mass index (ALM kg/height m2) < 5.5 kg/m2. Physical [...]

ABSTRACT Objective: To evaluate the prevalence of osteosarcopenia and the association of osteosarcopenia with trabecular bone score (TBS) in a group of patients with type 2 diabetes mellitus(T2DMG) compared with a paired control group (CG). Materials and methods: Cross-sectional study with men and women ≥ 50 years recruited by convenience. Patients in both groups answered questionnaires and underwent evaluation of bone mineral density (BMD), handgrip strength (HGS), and TBS. The T2DMG also underwent a gait speed (GS) test. Sarcopenia was […]

ABSTRACT Objective To establish percentile curves for measures and indices of body composition by age and sex and compare them with data from other ethnic groups. Subjects and methods Cross-sectional, population-based study with adults aged 20-59 years (n = 689). Percentile curves adjusted by a third degree polynomial function were constructed for skeletal mass index (SMI), fat mass index, body fat, and load-capacity metabolic indices (LCMI) based on dual-energy X-ray absorptiometry (DXA). Results SMIweight and SMIBMI showed decline from the […]

Objective Analyze the influence of sarcopenia in bone health of elderly men. Subjects and methods This cross-sectional study evaluated 198 men aged over 60 years. Body composition was measured by dual energy X-ray absorptiometry. The BMD was measured at the femoral neck, total hip, lumbar spine and 33% radius. The diagnosis of abnormal BMD was defined for men who presented densitometric diagnosis of osteopenia or osteoporosis defined by T-score of femoral neck, total hip and lumbar spine. The pre-sarcopenia and […]

Until recently obesity was believed to be protective against fractures. However, a report from a Fracture Liaison Clinic in the UK (2010) reported a surprisingly high proportion of obese postmenopausal women attending the clinic with fractures, and in the GLOW study (2011), a similar prevalence and incidence of fractures in obese and non-obese postmenopausal women was observed. Subsequently, other studies have demonstrated the importance of obesity in the epidemiology of fractures. Obese women are at increased risk of fracture in […]

Objectives : To evaluate relationships between nutritional status, sarcopenia and osteoporosis in older women. Subjects and methods : We studied 44 women, 67-94 years, by mini-nutritional assessment (MAN), glomerular filtration corr. 1.73 m2, body mass index (BMI), arm circumference and calf (CP and CB), bone mineral density and body composition, DXA (fat mass MG; lean MM). We gauge sarcopenia: IMM MM = MSS + MIS/height2. We used the Pearson correlation coefficient, p < 0.05 as significant. Results : MNA and […]
