Exercise is a form of physical activity (PA). PA is an important marker of health and quality of life in older adults. The purpose of this study was to conduct a systematic review of the literature to assess the effect of exercise-based interventions on an at least six-month follow up PA measure, and to describe the specific strategies implemented during the intervention to strengthen the sustainability of PA in community-dwelling 65+ year-old adults. We registered and conducted a systematic review and meta-analysis (PROSPERO: CRD42017070892) of randomized clinical trials (RCT). We searched three electronic databases during January 2018 to identify RCT assessing any type of exercise-based intervention. Studies had to report a pre-, post-, and at least 6-month post-intervention follow-up. To be included, at least one PA outcome had to be assessed. The effect of exercise-based interventions was assessed compared to active (e.g., a low-intensity type of exercise, such as stretching or toning activities) and non-active (e.g., usual care) control interventions at several time points. Secondary analyses were conducted, restricted to studies that reported specific strategies to enhance the sustainability of PA. The intervention effect was measured on self-reported and objective measures of time spent in PA, by means of standardized mean differences. Standardized mean differences of PA level were pooled. Pooled estimates of effect were computed with the DerSimonian–Laird method, applying a random effects model. The risk of bias was also assessed. We included 12 studies, comparing 18 exercise intervention groups to four active and nine non-active control groups. Nine studies reported specific strategies to enhance the long-term sustainability of PA. The strategies were mostly related to the self-efficacy, self-control, and behavior capability principles based on the social cognitive theory. Exercise interventions compared to active control showed inconclusive and heterogeneous results. When compared to non-active control, exercise interventions improved PA time at the six-months follow up (standardized mean difference (SMD) 0.30; 95%CI 0.15 to 0.44; four studies; 724 participants; I² 0%), but not at the one- or two-years follow-ups. No data were available on the mid- and long-term effect of adding strategies to enhance the sustainability of PA. Exercise interventions have small clinical benefits on PA levels in community-dwelling older adults, with a decline in the observed improvement after six months of the intervention cessation.

Due to the dramatic impact of the COVID-19 pandemic, Spain underwent a strict lockdown (March–May 2020). How the lockdown modified older adults’ physical activity (PA) has been poorly described. This research assesses the effect of the lockdown on PA levels and identifies predictors of sufficient/insufficient PA in frail older community-dwellers. Community-dwelling participants from the +ÀGIL Barcelona frailty intervention program, suspended during the pandemic, underwent a phone-assessment during the lockdown. PA was measured before and after the lockdown using the Brief Physical Activity Assessment Tool (BPAAT). We included 98 frail older adults free of COVID-19 (mean age = 82.7 years, 66.3% women, mean Short Physical Performance Battery = 8.1 points). About one third of participants (32.2%) were not meeting sufficient PA levels at the end of the lockdown. Depressive symptoms (OR = 0.12, CI95% = 0.02–0.55) and fatigue (OR = 0.11, CI95% = 0.03–0.44) decreased the odds of maintaining sufficient PA, whereas maintaining social networks (OR = 5.07, CI95% = 1.60–16.08) and reading (OR = 6.29, CI95% = 1.66–23.90) increased it. Living alone was associated with the reduction of PA levels (b = −1.30, CI95% = −2.14–−0.46). In our sample, pre-lockdown mental health, frailty-related symptoms and social relationships were consistently associated with both PA levels during-lockdown and pre-post change. These data suggest considering specific plans to maintain PA levels in frail older community-dwellers.

Introduction: Different remote interventions, such as applications (apps), have been used to continue promoting healthy ageing and preventing disability during the COVID-19 pandemic. The growing trend of apps in health is exponential and may facilitate scaling up physical activity prescription. Numerous tools are available, but little is known regarding their appropriateness, validation and recommendation, especially for frail older adults. Methods: In-house, we developed an application that makes both the Apple app Store and the Google Play Store searchable using topic-related keywords and facilitates the extraction of basic app-information of the search results. The study was aimed at apps available to an English-speaking market. The resulting apps were filtered using various inclusion and exclusion criteria. The resultant apps underwent a more in-depth characterisation and searches for scientific publications on each app website and PubMed. Results: From an initial search result of >2,800 apps, 459 met the initial inclusion criteria. After a more in-depth review of their features, 39 apps remained for possible app in older frail patients. After testing them, 22 apps were excluded. Seventeen apps fit the inclusion and exclusion criteria and were deemed appropriate after peer review. Of these, only one app, Vivifrail, had any type of publication/published evidence. Conclusion: Apps can be valuable tool in prescribing exercise for frail older adults living in the community. However, few apps seem useful on a large scale, and there is limited evidence to support their effectiveness. It is important to invest in adapting Information and Communication Technologies to this population group.

Sustained adherence is essential for the effectiveness of community-based multidomain interventions aimed at preventing disability in older adults with initial frailty. This study explores the perspectives of older adults and primary care professionals involved in the + AGIL Barcelona programme to understand the factors that facilitate or hinder sustained adherence and provide evidence for improving its implementation and scalability. A qualitative descriptive study was conducted in three primary care centres in Barcelona implementing the + AGIL programme. Participants were purposively selected to ensure information-rich perspectives. Six homogeneous focus groups were conducted with older adults meeting criteria for initial frailty (n = 22; mean age 82 years) and primary care professionals (n = 18), facilitated by two experienced qualitative researchers. Discussions were audio-recorded, transcribed verbatim, and analysed using reflexive thematic analysis. Rigour was ensured through independent coding, reflexive discussion, consensus, and data saturation confirmation. Adherence emerged as a multidimensional and context-dependent process shaped by professional, personal, and community-related factors. Empathetic communication, individualised exercise prescription, and group cohesion acted as key facilitators for motivation, autonomy, and the adoption of new healthy routines. Conversely, caregiving responsibilities, socioeconomic vulnerability, and limited access to community resources hindered the maintenance of behaviours over time. Organisational continuity and stronger healthcare-community coordination were perceived as essential for sustainability. Adherence to multidomain interventions depends not only on programme content but also on delivery processes and contextual embedding within participants' lived realities. Strengthening behavioural support and healthcare-community integration is vital to enhance long-term sustainability and scalability in primary care settings.
