Due to the lack of a uniform obesity definition, there is marked variability in reported sarcopenic obesity (SO) prevalence and associated health outcomes. We compare the association of SO with physical function using current Asian Working Group for Sarcopenia (AWGS) guidelines and different obesity measures to propose the most optimal SO diagnostic formulation according to functional impairment, and describe SO prevalence among community-dwelling young and old adults. ⋯ Our findings suggest FMI as the most preferred measure for obesity and support its use as a diagnostic criteria for SO.

Sarcopenic obesity (SO) is associated with poorer physical performance in the elderly and will increase in relevance with population ageing and the obesity epidemic. The lack of a consensus definition for SO has resulted in variability in its reported prevalence, poor inter-definitional agreement, and disagreement on its impact on physical performance, impeding further development in the field. While sarcopenia definitions have been compared, the impact of obesity definitions in SO has been less well-studied. ⋯ There is large variation in the prevalence of SO across different obesity definitions, with low-to-moderate agreement between them. Our results corroborate recent evidence that WC, and thus central obesity, is best associated with poorer muscle function in SO. Thus, WC should be further explored in defining obesity for accurate and early characterization of SO among older adults in Asian populations.

The association of physical activity (PA) intensities and duration spent in those activities with different walking tasks remains unclear. ⋯ Overall, the results of this study suggest that vigorous PA and maximal knee extension strength are two important factors that are associated with different walking speeds in older women.

Sarcopenia is the progressive loss of mass and skeletal muscle strength and has serious consequences on older people's health. The Chilean older population has a high life-expectancy, but the prevalence of functional dependence is also high. ⋯ The total prevalence of sarcopenia was 19.1% increasing with age reaching 39.6% in people of 80 or more years of age. A negative association of sarcopenia with overweight, obesity and lean/fat mass ratio was observed. Although the high prevalence of obesity (35.9%), only 2% of obese people were sarcopenic.

Observational Study
Influence of Age on Decision-Making Process to Limit or Withdraw Life-Sustaining Treatment in the Intensive Care Unit - A Single Center Prospective Observational Study.
The increasing age in the industrialized countries places significant demands on intensive care unit (ICU) resources and this triggers debates about end-of-life care for the elderly. ⋯ We found that age ≥70yo was an independent risk factor for DWLSTs for patients in the ICU, but not for their mortality. Reasons leading to DWLSTs are different according to the age of patients.
