Grip strength (GS) is widely used in various fields such as sports, rehabilitation, and geriatrics to assess muscle strength, and to diagnose sarcopenia and frailty in older adults. There is a potential for measurement differences among different dynamometers available, and studies comparing GS measurements by variable tools have conflicting results. The two most frequently used dynamometers are the Jamar hydraulic (Jamar) and spring-type hand grip dynamometers, and Jamar has not been compared to Jamar PLUS+ Digital (Jamar+) dynamometer in older adults. So, we aimed to assess GS measurements with the Jamar as the reference standard against Jamar+, and spring-type Takei T.KK. 5401 (Takei) digital dynamometers. One hundred and ten outpatients aged >60 years were included. Inter-instrumental reliability was determined. The differences between dynamometers were evaluated by Bland–Altman plots and measurement error. The measurements with Jamar+, and Takei dynamometers were reliable and valid regarding the Jamar dynamometer. Takei and Jamar+ dynamometers overestimated GS over the Jamar dynamometer. Though the differences in the measured values might be disregarded in clinical practice, individuals defined to have low GS varied by the use of different dynamometers. Grip strength better be measured by the same dynamometer in serial measurements of older individuals.

Background Malnutrition (i.e., protein-energy malnutrition) in older adults has severe negative clinical consequences, emphasizing the need for effective treatments. Many, often small, randomized controlled trials (RCTs) testing the effectiveness of nutritional interventions for the treatment of malnutrition showed mixed results and a need for meta-analyses and data pooling has been expressed. However, evidence synthesis is hampered by the wide variety of outcomes and their method of assessment in previous RCTs. This paper describes the protocol for developing a Core Outcome Set (COS) for nutritional intervention studies in older adults with malnutrition and those at risk. Methods The project consists of five phases. The first phase consists of a scoping review to identify frequently used outcomes in published RCTs and select additional patient-reported outcomes. The second phase includes a modified Delphi Survey involving experienced researchers and health care professionals working in the field of malnutrition in older adults, followed by the third phase consisting of a consensus meeting to discuss and agree what critical outcomes need to be included in the COS. The fourth phase will determine how each COS outcome should be measured based on a systematic literature review and a second consensus meeting. This will be followed by a dissemination and implementation phase. Patient and Public Involvement (PPI) representatives will contribute to study design, oversight, consensus, and dissemination. Conclusions The result of this project is a COS that should be included in any RCT evaluating the effect of nutritional interventions in older adults with malnutrition and those at risk. This COS will facilitate comparison of RCT results, will increase efficient use of research resources and will reduce bias due to measurement of the outcome and publication bias. Ultimately, the COS will support clinical decision making by identifying the most effective approaches for treating and preventing malnutrition in older adults.

Background Reports on psychological effects of quarantine during past outbreaks and pandemics showed that quarantined people were more likely to experience psychological problems than those who were not. It was also shown that there was an increase in anxiety, depression, and stress in all age groups during the COVID‐19 pandemic. So, we investigated emotional states and quality of life as components of general well‐being in older participants of University of the Third Age (U3A) attending online programs during the second year of the pandemic, and compared them with the pre‐pandemic COVID‐19 period. Methods This study was conducted among 27 participants of a U3A program. Data on sociodemographics, Charlson comorbidity index, the Geriatric Depression Scale Short Form (GDS‐SF), The Geriatric Anxiety Scale (GAS), and Turkish version of World Health Organization Quality of Life Instrument Older Adults Module (WHOQOL‐OLD) were taken in September 2019 and September 2021. Results The median age of the participants was 68 (60–75) years (81.5% female). In the COVID‐19 pandemic period; ‘Death and dying’ (except for ‘Fear of pain before death’ score), ‘Intimacy’ domain, and ‘Social participation’ domain scores of WHOQOL‐OLD decreased compared to the pre‐pandemic period ( P < 0.001, P = 0.011, and P < 0.001, respectively) whereas the scores for GAS and GDS‐SF were higher ( P < 0.001 and P = 0.011). The reason for the decrease in ‘Social participation’ domain scores was the decrease in ‘Satisfaction with opportunity to participate in community’. There was no significant difference in ‘Autonomy’ domain of WHOQOL‐OLD ( P = 0.598). Conclusion Although there was no change in ‘Autonomy’ domain among the participants of U3A before and during the pandemic period, anxiety and depression scores were higher in the second year of the COVID pandemic. Only a decrease in satisfaction with opportunity to participate in community might have significant impact on social participation.
