BackgroundIn elderly persons frailty and malnutrition are very common and can lead to serious health hazards such as increased mortality, morbidity, dependency, institutionalization and a reduced quality of life. In Austria, the prevalence of frailty and malnutrition are increasing steadily and are becoming a challenge for our social system. Physical training and adequate nutrition may improve this situation.Methods/designIn this randomized controlled trial, 80 malnourished frail community-dwelling patients (≥ 65 years) hospitalized at wards for internal medicine are recruited. Additionally, 80 lay volunteers (≥ 50 years), named buddies are recruited and subsequently trained regarding health enhancing physical activity and nutrition in four standardized training sessions. These buddies visit the malnourished frail persons at home twice a week for about one hour during an initial period of 10–12 weeks. While participants allocated to the intervention group (n = 40) receive intervention to improve their fluid intake, protein and energy intake, perform strength training and try to increase their baseline activities, the control group (n = 40) only gets home visits without any intervention. After 10–12 weeks, both, the intervention and the control group, receive the nutritional intervention and the physical training. Health, nutritional and frailty status, physical fitness, body composition and chronic inflammation of buddies and frail persons are recorded before the intervention, after 10–12 weeks, 6 and 12 months.DiscussionTo your knowledge this trial is the first of its kind to provide nutritional and physical activity interventions to malnourished frail community-dwelling persons by trained lay buddies, in which an improvement of the frail persons´ and the buddies’ health status is measured. This study assesses the efficacy of such an intervention and may offer new perspectives for the management of frailty and malnutrition.Trail registrationClinicalTrials.gov, NCT01991639

PurposeThe aim of this study was to examine the associations between daily physical activity (DPA), handgrip strength, appendicular skeletal muscle mass (ASMM) and physical performance (balance, gait speed, chair stands) with quality of life in prefrail and frail community-dwelling older adults.MethodsPrefrail and frail individuals were included, as determined by SHARE-FI. Quality of life (QoL) was measured with WHOQOL-BREF and WHOQOL-OLD, DPA with PASE, handgrip strength with a dynamometer, ASMM with bioelectrical impedance analysis and physical performance with the SPPB test. Linear regression models adjusted for sex and age were developed: In model 1, the associations between each independent variable and QoL were assessed separately; in model 2, all the independent variables were included simultaneously.ResultsEighty-three participants with a mean age of 83 (SD: 8) years were analysed. Model 1: DPA (ß = 0.315), handgrip strength (ß = 0.292) and balance (ß = 0.178) were significantly associated with ‘overall QoL’. Balance was related to the QoL domains of ‘physical health’ (ß = 0.371), ‘psychological health’ (ß = 0.236), ‘environment’ (ß = 0.253), ‘autonomy’ (ß = 0.276) and ‘social participation’ (ß = 0.518). Gait speed (ß = 0.381) and chair stands (ß = 0.282) were associated with ‘social participation’ only. ASMM was not related to QoL. Model 2: independent variables explained ‘overall QoL’ (R 2 = 0.309), ‘physical health’ (R 2 = 0.200), ‘autonomy’ (R 2 = 0.247) and ‘social participation’ (R 2 = 0.356), among which balance was the strongest indicator.ConclusionASMM did not play a role in the QoL context of the prefrail and frail older adults, whereas balance and DPA were relevant. These parameters were particularly associated with ‘social participation’ and ‘autonomy’.

A randomized controlled trial was performed to compare the effects of a home-based physical and nutritional intervention program carried out by lay-volunteers to home visits with social support alone. Buddies visited 80 prefrail or frail older persons at home twice a week for 12 weeks. The physical training and nutrition group (PTN, n = 39) performed two sets of six strength exercises, discussed nutritional topics and received social support. The social support group (SoSu, n = 41) received home visits with social support only. In the PTN group, handgrip strength increased significantly by 2.4 kg (95% CI: 1.0–3.8). In the SoSu group we did not see a significant improvement. However, no significant between-group difference was found. Physical performance increased in both groups, although with a higher increase of 1.0 point (95% CI: 0.1–2.0) in the PTN group. In none of the groups muscle mass changed. Further results showed that frail individuals benefit more from the intervention than prefrail individuals (OR: 2.78; 95% CI: 1.01–7.66). Handgrip strength in the intervention group increased by a clinically relevant value and this effect is comparable to that obtained by health-care professionals. Therefore, home visits with a physical training and nutritional program could offer a new perspective in the care of community-dwelling prefrail and frail older persons.
