Sarcopenia and its association with objectively measured life-space mobility and moderate-to-vigorous physical activity in the oldest-old amid the COVID-19 pandemic when a physical distancing policy is in force.

INTRODUCTION: The oldest-old are highly vulnerable to sarcopenia. Physical distancing remains a common and effective infection-control policy to minimize the risk of COVID-19 transmission during the pandemic. Sarcopenia is known to be associated with impaired immunity. Moderate-to-vigorous physical activity (MVPA) and life-space mobility (LSM) are potential strategies for minimizing the risk of sarcopenia. However, a physical distancing policy might jeopardize the practice of MVPA and LSM. The purposes of this study were to identify the prevalence of sarcopenia and examine the association between MVPA and LSM with sarcopenia in the community-dwelling oldest-old during the COVID-19 pandemic. METHODS: This study employed a cross-sectional and observational design. The study was conducted in 10 community centres for older people in Hong Kong during the period of the COVID-19 pandemic (September to December 2020). Eligible participants were the oldest-old people aged ≥85 years, who were community-dwelling and had no overt symptoms of cognitive impairment or depression. Key variables included sarcopenia as measured by SARC-F, LSM as measured by a GPS built into smartphones, and MVPA as measured by a wrist-worn ActiGraph GT3X+. Variables were described by mean and frequency. A multiple linear regression was employed to test the hypotheses. The dependent variable was sarcopenia and the independent variables included LSM and MVPA. RESULTS: This study recruited 151 eligible participants. Their mean age was 89.8 years and the majority of them were female (n = 93/151, 61.6%). The prevalence of sarcopenia was 24.5% (n = 37/151) with a margin of error of 6.86%. MVPA was negatively associated with sarcopenia in older people (ß = - 0.002, SE = 0.001, p = 0.029). However, LSM was not associated with sarcopenia. CONCLUSION: The prevalence of sarcopenia in the community-dwelling oldest-old population is high. MVPA is negatively associated with sarcopenia. LSM is unrelated to sarcopenia. Sarcopenia should be recognized and the oldest-old with sarcopenia should be accorded priority treatment during the COVID-19 pandemic.

Student nurses' perception and understanding of elder abuse.

AIM: The aim of this study is to investigate student nurses' perception, knowledge and awareness of elder abuse. BACKGROUND: It is evidential that elder abuse tends to be unrecognized and is often hidden from public awareness. Nurses who work with older people are expected to be knowledgeable of the causes and detection of elder abuse. DESIGN: A quantitative approach using a questionnaire was used to collect data from 245 student nurses from year 1 and 3 of a 4-year bachelor's degree programme. METHOD: Convenience sampling was used to recruit participants from the two cohorts of the nursing programme. A 25-item questionnaire was used to investigate participants' perception and awareness of elder abuse. RESULTS: Some 47.8% (n=86) year 1 students and 76.9% (n=50) year 3 students perceived that they were not well trained in identifying or handling elder abuse. Year 1 and 3 students ranked the top three most common abuses differently. In addition, 38% of year 3 students thought that it was largely the responsibility of social workers rather than nurses, to deal with cases of elder abuse. CONCLUSIONS: The study reveals that nurses-to-be, who are generally expected to be part of the joint force to protect older people against abuse, did not find themselves adequately prepared to fulfil this responsibility. RELEVANCE TO CLINICAL PRACTICE: The findings provide useful information from which more comprehensive content about elder abuse can be developed in the gerontological nursing curriculum, to better prepare future nurses by increasing their basic understanding of elder abuse.
