[What needs do experts and future Physical Activity and Sport professionals perceive to promote healthy aging? Professionals and students' views]. / ¿Qué necesidades perciben los expertos y los futuros profesionales de la Actividad Física y del Deporte para promover un envejecimiento saludable? Visión de profesionales y estudiantes.

INTRODUCTION: Physical activity acts as an adjuvant in the treatment of numerous diseases and in the promotion of healthy aging. Increasing longevity entails an increase in the demand for professionals who prescribe physical activity, specifically physiotherapists and physical-activity educators. OBJECTIVES: The main objective of this study was to explore the perceptions of a group of third- and fourth-year Physiotherapy students (n=9) and Sport Sciences students (n=5), and experts who work with older adults (n=3) about their knowledge of the older adult population and healthy aging. The secondary objectives were to: (a) explore what knowledge future professionals need about physical activity programming and about physical activity programs aimed at maintaining and improving health among older adults; (b) explore what would be the best methodology to acquire such knowledge; and (c) explore whether a relationship is perceived between knowledge about the older adult population and motivation to work with this population group. METHODS: Two discussion groups with students and three interviews with experts were conducted. Discussion groups and interviews were transcribed verbatim and analyzed through a reflexive thematic analysis, following the steps described by Braun and Clarke (2021). RESULTS: Three themes were identified from the discussion groups: (1) conception and ideas about older adults, (2) skills and knowledge perceived as important, and (3) proposals for motivational intervention addressed to the older population. Four themes were identified from the interviews with experts: (1) characteristics of the future professional, (2) physical activity programs for older people: the recipe for success, (3) the role of enjoyment as key to success, and (4) barriers/obstacles along the path. CONCLUSION: Students of both degrees and experts believe that more practical training opportunities are needed, to enable students to interact with the older population and get to know their needs, motivations, and barriers, to increase physical activity levels in this population group.

Nature-based social interventions to address loneliness among vulnerable populations: a common study protocol for three related randomized controlled trials in Barcelona, Helsinki, and Prague within the RECETAS European project.

BACKGROUND: The negative effects of loneliness on population health and wellbeing requires interventions that transcend the medical system and leverage social, cultural, and public health system resources. Group-based social interventions are a potential method to alleviate loneliness. Moreover, nature, as part of our social and health infrastructure, may be an important part of the solutions that are needed to address loneliness. The RECETAS European project H2020 (Re-imagining Environments for Connection and Engagement: Testing Actions for Social Prescribing in Natural Spaces) is an international research project aiming to develop and test the effectiveness of nature-based social interventions to reduce loneliness and increase health-related quality of life. METHODS: This article describes the three related randomized controlled trials (RCTs) that will be implemented: the RECETAS-BCN Trial in Barcelona (Spain) is targeting people 18+ from low socio-economic urban areas; the RECETAS-PRG Trial in Prague (Czech Republic) is addressing community-dwelling older adults over 60 years of age, and the RECETAS-HLSNK trial is reaching older people in assisted living facilities. Each trial will recruit 316 adults suffering from loneliness at least sometimes and randomize them to nature-based social interventions called "Friends in Nature" or to the control group. "Friends in Nature" uses modifications of the "Circle of Friends" methodology based on group processes of peer support and empowerment but including activities in nature. Participants will be assessed at baseline, at post-intervention (3 months), and at 6- and 12-month follow-up after baseline. Primary outcomes are the health-related quality-of-life according to 15D measure and The De Jong Gierveld 11-item loneliness scale. Secondary outcomes are health and psychosocial variables tailored to the specific target population. Nature exposure will be collected throughout the intervention period. Process evaluation will explore context, implementation, and mechanism of impact. Additionally, health economic evaluations will be performed. DISCUSSION: The three RECETAS trials will explore the effectiveness of nature-based social interventions among lonely people from various ages, social, economic, and cultural backgrounds. RECETAS meets the growing need of solid evidence for programs addressing loneliness by harnessing the beneficial impact of nature on enhancing wellbeing and social connections.

Subjective psychological impacts during COVID-19 lockdown on older people, risk profiles and coping strategies: Results of an online survey in Spain.

This study explores the psychological impacts of lockdown among older people during the coronavirus disease 2019 pandemic in Spain, and identifies risk profiles and adaptative behaviors. A cross-sectional online survey was disseminated by social networks through snowball sampling (April-June 2020). The survey included ad-hoc questions about psychological impacts on subjective cognitive functioning, emotional distress, and loneliness. Open end-questions were coded according to Lazarus and Folkman's coping strategies framework. Of the 2010 respondents, 76% experienced impact in at least one cognitive function (11% reporting severe effects), 78% frequent sadness and 13% frequent loneliness. Age 80+, women and low education increased the risk of loneliness and severe impact in memory and processing speed. Living alone was an additional risk factor for loneliness and sadness. Lockdown is associated with cognitive impacts, emotional distress, and loneliness being risk profiles related to inequality axes. Coping strategies should inform aging policies to prevent psychological impacts during the lockdown.

How did the COVID-19 pandemic affect urinary incontinence and its management in the nursing homes? A descriptive phenomenological study.

BACKGROUND: Management of urinary incontinence (UI) in nursing homes (NHs) represents a complex process that may have become more challenging during a period in which front-line health professionals (HPs) must deal with the outbreak of a new infectious disease. We aimed to investigate how UI and its management was affected in NHs during the COVID-19 pandemic based on the perception of health professionals. METHODS: This qualitative study was conducted between January and March 2021 with 16 health professionals working in nine NHs in the Osona county (Barcelona, Spain) during the COVID-19 pandemic. The individual interviews were conducted via online videoconferencing and each session was audio recorded. RESULTS: The HPs highlighted that the COVID-19 pandemic affected the management of continence in NHs, resulting in increased UI. Two main factors were identified: workforce-related and resident-related factors. Considering the workforce, three main topics emerged: pandemic as the priority, lack of personnel and use of personal protective equipment as an obstacle to communication with residents and attending to their needs. CONCLUSION: Managing UI in NHs always has been a challenging point of care, and these challenges were worsened by the restrictions and additional difficulties that arose during the COVID-19 pandemic.

Is education level, as a proxy for socio-economic position, related to device-measured and self-reported sedentary behavior in European older adults? A cross-sectional study from the SITLESS project.

Background: Sedentary behavior (SB) is a determinant of health in older adult people. Educational level is a primary driver of health disparities and is demonstrated to be a reliable measure of socioeconomic position. We aimed to examine the associations between educational level and self-reported along with device-measured SB in older adults living in Europe and the association of mentally active and passive SB domains with the educational level and gender in these associations. Methods: The design is cross-sectional. One thousand three hundred and sixty participants aged 65 and over (75.3±6.3 years old, 61.8% women) participated. Inclusion criteria were scored with the Short Physical Performance Battery. Variables that describe the sample were assessed with an interview, and device-measured SB was assessed with an accelerometer. SB was assessed with the Sedentary Behavior Questionnaire and an accelerometer. Multiple linear regression models were used to study the association between the level of education and SB. Results: Participants self-reported an average of 7.82 (SD: 3.02) daily waking hours of SB during weekend days, and the average of device-measured SB was 11.39 (1.23) h. Total mentally active SB (weekdays and weekends) was associated with the education level (p < 0.000). Participants were more sedentary during the week than during weekends, regardless of level of education (p < 0.000). Education level was significantly associated with self-reported mean hours per day in 46SB (p = 0.000; R=0.026; 95%CI). Conclusion: Low education level in older adults is associated with self-reported SB but not with objective SB measures.

Cost-effectiveness of a programme to address sedentary behaviour in older adults: results from the SITLESS RCT.

BACKGROUND: This study details the within-trial economic evaluation and long-term economic model of SITLESS, a multi-country, three-armed randomized controlled trial comparing a combined intervention of exercise referral schemes (ERS) enhanced by self-management strategies (SMS) against ERS alone and usual care (UC). METHODS: A cost-utility analysis, conducted from the base-case perspective of the National Health Service and personal and social services, estimated the incremental cost per incremental quality-adjusted life year (QALY) and years in full capability (YFC). A secondary analysis combined the costs with a broad set of outcomes within a cost-consequence framework, from a societal perspective. A Markov-type decision-analytic model was developed to project short-term changes in physical activity to long-term outcomes and costs, over a 5- and 15-year time horizon. RESULTS: The results of the within-trial analysis show that SMS+ERS is highly likely to be cost-effective compared to ERS alone (ICER €4270/QALY), but not compared to UC. Participants allocated to the SMS+ERS group also showed an improvement in YFC compared to ERS alone and UC. The long-term analysis revealed that SMS+ERS is likely to be a cost-effective option compared to ERS and UC over a 5-year, but not with a 15-year horizon, being then dominated by ERS alone. CONCLUSION: This research provides new evidence that SMS is a cost-effective add-on to ERS strategies. This economic evaluation informs the case for further, cost-effective, refinement of lifestyle change programmes targeted to older adults, with the aim of ultimately reducing the impact of non-communicable diseases in this population.

Urinary Incontinence and Its Association with Physical and Psycho-Cognitive Factors: A Cross-Sectional Study in Older People Living in Nursing Homes.

Urinary incontinence (UI) is a common geriatric syndrome affecting bladder health and is especially prevalent in nursing homes (NHs). The aim of the study was to determine the prevalence of UI and its associated factors in five Spanish NHs. UI (measured with Minimum Data Set 3.0), sociodemographic, and health-related variables were collected. Chi-square (or Fisher's) or Student's t-test (or Mann Whitney U) for bivariate analysis were used, with Prevalence Ratio (PR) as an association measure. The prevalence of UI was 66.1% (CI:95%, 53.6-77.2) in incontinent (n = 45, mean age 84.04, SD = 7.7) and continent (n = 23, mean age 83.00, SD = 7.7) groups. UI was significantly associated with frailty (PR = 1.84; 95%CI 0.96-3.53), faecal incontinence (PR = 1.65; 95%CI 1.02-2.65), anxiety (PR = 1.64; 95%CI 1.01-2.66), physical performance (PR = 1.77; 95%CI 1.00-3.11), and cognitive state (PR = 1.95; 95%CI 1.05-3.60). Statistically significant differences were found between incontinent and continent NH residents for limitations in activities of daily living (ADL), mobility, quality of life, sedentary behaviour, and handgrip strength. It can be concluded that two out of three of the residents experienced UI, and significant associated factors were mainly physical (sedentary behaviour, frailty, physical performance, ADL limitations, mobility, faecal incontinence, and handgrip strength) followed by psycho-cognitive factors (cognition, anxiety, and quality of life).

The Expert Caregiver Intervention Targeting Former Caregivers in Finland: A Co-Design and Feasibility Study Using Mixed Methods.

Informal caregivers face risks of social isolation. Given the high prevalence of informal caregivers in Europe, a considerable proportion of the population are also former caregivers. The Finnish Expert Caregiver intervention sought to train former caregivers to become volunteers aiming to support current caregivers through mainly peer support. The aims of this mixed method non-controlled exploratory intervention study were to assess the feasibility of the Finnish Expert Caregiver intervention by co-designing and implementing the intervention, and by assessing demand and practicality with special attention to the impact of COVID-19. The findings imply that the intervention was feasible as it resulted in a co-designed training course consisting of 30 h with 25 participants enrolling and 19 of them trying volunteering activities. The participants reported high scores on well-being at all timepoints of study, however, without statistically significant differences. The analysis of the focus group interviews revealed that the Expert Caregivers experienced the intervention as meaningful and offered them a sense of belonging with the other participants. Apart from using their caregiving past as an asset, the participants also took advantage of other personal skills and resources. Risks of adverse effects were related to the participants' expectations on their own contribution, demanding peer support recipients, poorly functioning peer support groups, and insufficient distance to one's caregiving past. The participants stressed the need for continuing support from intervention facilitators. Future studies with larger samples should investigate whether the effects differ between subgroups of participants and explore the perspective of the peer support recipients.

Barriers and potential solutions in the recruitment and retention of older patients in clinical trials-lessons learned from six large multicentre randomized controlled trials.

BACKGROUND: older people remain underrepresented in clinical trials, and evidence generated in younger populations cannot always be generalized to older patients. OBJECTIVE: to identify key barriers and to discuss solutions to specific issues affecting recruitment and retention of older participants in clinical trials based on experience gained from six current European randomised controlled trials (RCTs) focusing on older people. METHODS: a multidisciplinary group of experts including representatives of the six RCTs held two networking conferences and compiled lists of potential barriers and solutions. Every item was subsequently allocated points by each study team according to how important it was perceived to be for their RCTs. RESULTS: the six RCTs enrolled 7,612 older patients. Key barriers to recruitment were impaired health status, comorbidities and diverse health beliefs including priorities within different cultural systems. All trials had to increase the number of recruitment sites. Other measures felt to be effective included the provision of extra time, communication training for the study staff and a re-design of patient information. Key barriers for retention included the presence of severe comorbidities and the occurrence of adverse events. Long study duration, frequent study visits and difficulties accessing the study site were also mentioned. Solutions felt to be effective included spending more time maintaining close contact with the participants, appropriate measures to show appreciation and reimbursement of travel arrangements. CONCLUSION: recruitment and retention of older patients in trials requires special recognition and a targeted approach. Our results provide scientifically-based practical recommendations for optimizing future studies in this population.

"Not Alone in Loneliness": A Qualitative Evaluation of a Program Promoting Social Capital among Lonely Older People in Primary Health Care.

The weekly group-based program "Paths: from loneliness to participation" was conducted face-to-face over 15 sessions by nurses, social workers and volunteers in primary care in Catalonia (Spain) to alleviate loneliness among older people by promoting peer support and participation in community assets. We aimed at exploring participants' experiences of loneliness and participation prior to the program and its perceived benefits. The qualitative design was descriptive-interpretative. Data were collected through three focus groups and 41 interviews applying a semistructured topic guide involving 26 older participants, six professionals and nine volunteers. Participant-observation of all sessions involved the 38 older people who started the program. A thematic content analysis was applied. Older persons with diverse profiles of loneliness and participation explained different degrees of decrease in loneliness, an increase in participation in local community assets, companionship, peer support and friendship, and an empowerment process. Successful cases reported improvements in mental wellbeing and recovering the sense that life was worth living. Loneliness persisted among some widowed participants and vulnerabilities hampered some benefits. Participants, professionals and volunteers reported different degrees of success in older people to alleviate loneliness by enhancing social relationships and activities through complex processes interrelated with health and socioeconomic factors.

The Mediating Role of Self-Regulation and Self-Efficacy on Physical Activity Change in Community-Dwelling Older Adults (≥65 Years): An Experimental Cross-Lagged Analysis Using Data From SITLESS.

Improving the capacity for physical activity interventions to maintain behavior change is a key public health concern and an important strategy for the health and independence of older adults. Ways of ensuring effective maintenance of physical activity levels in older adults are unclear. This study includes the objective measure of moderate-to-vigorous physical activity (MVPA); self-reported self-efficacy; and self-regulation at four timepoints (baseline, intervention completion at 4 months, 12-, and 18-month follow-up) from the SITLESS study, a clinical trial conducted with a cohort of community-dwelling older adults (≥65 years) from Denmark, Germany, Spain, and the United Kingdom. A cross-lagged analysis found that self-regulation and self-efficacy may be key determinants of MVPA behavior in community-dwelling older adults. More specifically, the use of behavioral support strategies represents an important correlate of MVPA behavior, and its association with MVPA may be mediated by self-regulation and self-efficacy in older adults in the short and long term.

Older Adults' Experiences of a Physical Activity and Sedentary Behaviour Intervention: A Nested Qualitative Study in the SITLESS Multi-Country Randomised Clinical Trial.

BACKGROUND: The SITLESS programme comprises exercise referral schemes and self-management strategies and has been evaluated in a trial in Denmark, Spain, Germany and Northern Ireland. The aim of this qualitative study was to understand the implementation and contextual aspects of the intervention in relation to the mechanisms of impact and to explore the perceived effects. METHODS: Qualitative methodologies were nested in the SITLESS trial including 71 individual interviews and 12 focus groups targeting intervention and control group participants from postintervention to 18-month follow-up in all intervention sites based on a semi-structured topic guide. RESULTS: Overarching themes were identified under the framework categories of context, implementation, mechanisms of impact and perceived effects. The findings highlight the perceived barriers and facilitators to older adults' engagement in exercise referral schemes. Social interaction and enjoyment through the group-based programmes are key components to promote adherence and encourage the maintenance of targeted behaviours through peer support and connectedness. Exit strategies and signposting to relevant classes and facilities enabled the maintenance of positive lifestyle behaviours. CONCLUSIONS: When designing and implementing interventions, key components enhancing social interaction, enjoyment and continuity should be in place in order to successfully promote sustained behaviour change.

Urinary incontinence and sedentary behaviour in nursing home residents in Osona, Catalonia: protocol for the OsoNaH project, a multicentre observational study.

INTRODUCTION: Several studies have shown that physical activity (PA) levels and sedentary behaviour (SB) are independent risk factors for many health-related issues. However, there is scarce evidence supporting the relationship between SB and urinary incontinence (UI) in community-dwelling older adults, and no information on any possible association in institutionalised older adults. Stage I of this project has the main objective of determining the prevalence of UI and its associated factors in nursing home (NH) residents, as well as analysing the association between UI (and its types) and SB. Stage II aims to investigate the incidence and predictive factors of functional and continence decline, falls, hospitalisations, mortality and the impact of the COVID-19 pandemic among NH residents. METHODS AND ANALYSIS: Stage I is an observational, multicentre, cross-sectional study with mixed methodology that aims to explore the current status of several health-related outcomes in NH residents of Osona (Barcelona, Spain). The prevalence ratio will be used as an association measure and multivariate analysis will be undertaken using Poisson regression with robust variance. Stage II is a 2-year longitudinal study that aims to analyse functional and continence decline, incidence of falls, hospitalisations, mortality and the impact of the COVID-19 pandemic on these outcomes. A survival analysis using the actuarial method for functional decline and continence, evaluated every 6 months, and the Kaplan-Meier method for falls, hospitalisations and deaths, and Cox regression for multivariate analysis will be undertaken. ETHICS AND DISSEMINATION: The study received the following approvals: University of Vic - Central University of Catalonia Ethics and Research Committee (92/2019 and 109/2020), Clinical Research Ethics Committee of the Osona Foundation for Health Research and Education (FORES) (code 2020118/PR249). Study results will be disseminated at conferences, meetings and through peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT04297904.

Promoting social capital, self-management and health literacy in older adults through a group-based intervention delivered in low-income urban areas: results of the randomized trial AEQUALIS.

BACKGROUND: Evidence is scarce on how to promote health and decrease cumulative inequalities for disadvantaged older people. Downstream complex interventions focusing on intermediate factors (self-management, health literacy and social capital) may have the potential to mitigate the inequitable impacts of social determinants in health. The aim of the AEQUALIS study was to assess the effectiveness of a group-based intervention to improve self-perceived health as indicator of health inequality. METHODS: Pragmatic randomised clinical trial addressed to older adults (≥ 60 years) living in urban disadvantaged areas with low self-perceived health. The intervention was delivered in primary care settings and community assets between 2015 and 2017 and consisted in 12 weekly sessions. The primary outcome was self-perceived health assessed in two ways: with the first item of the SF-12 questionnaire, and with the EQ-5D visual analog scale. Secondary outcomes were health-related quality of life, social capital, self-management, mental health and use of health services. Outcomes were assessed at baseline, post intervention and follow-up at 9 months after the end of the intervention. RESULTS: 390 people were allocated to the intervention group (IG) or the control group (CG) and 194 participants and 164 were included in the data analysis, respectively. Self perceived health as primary outcome assessed with SF-12-1 was not specifically affected by the intervention, but with the EQ-5D visual analog scale showed a significant increase at one-year follow-up only in the IG (MD=4.80, 95%CI [1.09, 8.52]). IG group improved health literacy in terms of a better understanding of medical information (- 0.62 [- 1.10, - 0.13]). The mental component of SF-12 improved (3.77 [1.82, 5.73]), and depressive symptoms decreased at post-intervention (- 1.26 [- 1.90, - 0.63]), and at follow-up (- 0.95 [- 1.62, - 0.27]). The use of antidepressants increased in CG at the follow-up (1.59 [0.33, 2.86]), while it remained stable in the IG. CONCLUSIONS: This study indicates that a group intervention with a strong social component, conducted in primary health care and community assets, shows promising effects on mental health and can be used as a strategy for health promotion among older adults in urban disadvantaged areas.

Is loneliness a predictor of the modern geriatric giants? Analysis from the survey of health, ageing, and retirement in Europe.

BACKGROUND: The modern Geriatric Giants have evolved to encompass four new syndromes, of frailty (linked to fatigue and physical inactivity), sarcopenia, anorexia of ageing, and cognitive impairment. In parallel, loneliness has been established as a risk factor for adverse mental and physical health outcomes among older adults. OBJECTIVE: To analyse loneliness as a predictor of the modern Geriatric Giants in European older adults, using a longitudinal design of nationally representative data. DESIGN: Longitudinal population-based cohort study. SUBJECTS: Data from countries that participated in waves 5 and 6 of the Survey of Health, Ageing, and Retirement in Europe project. The sizes of the subsamples analysed ranged from 17,742 for physical inactivity to 24,524 for anorexia of ageing. METHODS: Loneliness (measured from wave 5) was the independent variable of interest. The dependent variables were incidence of fatigue, physical inactivity, sarcopenia, anorexia of ageing, and cognitive impairment from wave 5 (baseline) to wave 6. Poisson regression models were used for multivariable analysis, obtaining Relative Risk (RR) and 95 % confidence intervals (CI). RESULTS: The prevalence of loneliness ranged from 9.2%-12.4% at wave 5. The 2-year incidence of fatigue was 16 % (95 % CI: 15.5-16.5), physical inactivity 9.8 % (95 % CI: 9.4-10.3), sarcopenia 5.6 % (95 % CI: 5.3-5.9), anorexia of aging 5.4 % (95 % CI: 5.1-5.7), and cognitive impairment 10.3 % (95 % CI: 9.9-10.8). The multivariable analysis showed that loneliness was a predictive factor for fatigue (30 %, CI: 17-45 % higher risk), physical inactivity (24 %, CI: 7-43 % higher risk) and cognitive impairment (26 %, CI: 9-46 % higher risk), adjusted by age, sex, number of chronic diseases, education level, region and depression. CONCLUSIONS: Loneliness is an independent risk factor for fatigue, physical inactivity, and cognitive impairment in older adults. The incidence of anorexia of ageing and sarcopenia was not associated with loneliness over the 2-year observation period.

IMAGINE study protocol of a clinical trial: a multi-center, investigator-blinded, randomized, 36-month, parallel-group to compare the effectiveness of motivational interview in rehabilitation of older stroke survivors.

BACKGROUND: Rehabilitation pathways are crucial to reduce stroke-related disability. Motivational Interviewing (MI), as a person-centered complex intervention, aimed to empower and motivate, and could be a resource to improve rehabilitation outcomes for older stroke survivors. The IMAGINE project aims to assess the impact of MI, as a complement to standard geriatric rehabilitation, on functional improvement at 30 days after admission, compared to standard geriatric rehabilitation alone, in persons admitted to geriatric rehabilitation after a stroke. Secondary objectives include assessing the impact of MI on physical activity and performance, self-efficacy, safety, cost-utility, participants' experiences and functional status at 3 months. METHODS: We will conduct a multicenter randomized clinical trial in three geriatric rehabilitation hospitals in Spain. Older adults after mild-moderate stroke without previous severe cognitive impairment or disability will be randomized into the control or intervention group (136 per group, total N = 272). The intervention group will receive 4 sessions of MI by trained nurses, including the design of a personalized rehabilitation plan agreed between stroke survivors and nurses based on stroke survivors´ goals, needs, preferences and capabilities. Main outcome will be the Functional Independence Measure (FIM). In-hospital physical activity will be measured through accelerometers and secondary outcomes using validated scales. The study includes a process evaluation and cost-utility analysis. DISCUSSION: Final results are expected by end of 2020. This study will provide relevant information on the implementation of MI as a rehabilitation reinforcement tool in older stroke survivors. A potential reduction in post-stroke disability and dependence would increase person's health-related quality of life and well-being and reduce health and social care costs. IMAGINE has the potential to inform practice and policymakers on how to move forward towards shared decision-making and shared responsibilities in the vulnerable population of older stroke survivors.

Sedentary behavior, physical activity, and mental health in older adults: An isotemporal substitution model.

INTRODUCTION: Regular moderate-to-vigorous physical activity (MVPA) is associated with improved mental health, but the evidence for the effect of reducing sedentary behavior (SB) or increasing light PA (LPA) in older adults is lacking. Using isotemporal substitution (IS) models, the aim of this paper was to investigate the effect of substituting SB with LPA or MVPA on associations with mental health in older adults. METHODS: Data from 1360 older adults (mean age 75.18 years) in four countries were utilized. PA and SB was measured using ActiGraph wGT3X-BT + accelerometers worn for 7 days. Self-rated mental health was measured using the Hospital and Anxiety Depression Scale (HADS). IS models estimated cross-sectional associations when 30 minutes of one behavior was substituted with another. Models were adjusted for age, sex, marital status, and educational attainment. RESULTS: Substituting 30 minutes of SB with LPA (ß -.37; 95% CI -0.42, -0.32) or MVPA (ß -.14; 95% CI -0.21, -0.07) and substituting LPA with MVPA (ß -.11; 95% CI -0.18, -0.04) were associated with improvements in anxiety. However, substituting 30 minutes of SB with LPA (ß .55; 95% CI 0.49, 0.62) was associated with increased depression. CONCLUSION: Replacing 30 minutes of SB with LPA or MVPA was associated with improved anxiety symptoms in older adults. Greater benefits were observed when shifting SB and LPA to MVPA.

The effectiveness and complexity of interventions targeting sedentary behaviour across the lifespan: a systematic review and meta-analysis.

BACKGROUND: Evidence suggests that sedentary behaviour (SB) is associated with poor health outcomes. SB at any age may have significant consequences for health and well-being and interventions targeting SB are accumulating. Therefore, the need to review the effects of multicomponent, complex interventions that incorporate effective strategies to reduce SB are essential. METHODS: A systematic review and meta-analysis were conducted investigating the impact of interventions targeting SB across the lifespan. Six databases were searched and two review authors independently screened studies for eligibility, completed data extraction and assessed the risk of bias and complexity of each of the included studies. RESULTS: A total of 77 adult studies (n=62, RCTs) and 84 studies (n=62, RCTs) in children were included. The findings demonstrated that interventions in adults when compared to active controls resulted in non-significant reductions in SB, although when compared to inactive controls significant reductions were found in both the short (MD -56.86; 95%CI -74.10, -39.63; n=4632; I2 83%) and medium-to-long term (MD -20.14; 95%CI -34.13, -6.16; n=4537; I2 65%). The findings demonstrated that interventions in children when compared to active controls may lead to relevant reductions in daily sedentary time in the short-term (MD -59.90; 95%CI -102.16, -17.65; n=267; I2 86%), while interventions in children when compared to inactive controls may lead to relevant reductions in the short-term (MD -25.86; 95%CI -40.77, -10.96; n=9480; I2 98%) and medium-to-long term (MD -14.02; 95%CI -19.49, -8.55; n=41,138; I2 98%). The assessment of complexity suggested that interventions may need to be suitably complex to address the challenges of a complex behaviour such as SB, but demonstrated that a higher complexity score is not necessarily associated with better outcomes in terms of sustained long-term changes. CONCLUSIONS: Interventions targeting reductions in SB have been shown to be successful, especially environmental interventions in both children and adults. More needs to be known about how best to optimise intervention effects. Future intervention studies should apply more rigorous methods to improve research quality, considering larger sample sizes, randomised controlled designs and valid and reliable measures of SB.

Accelerometer-Measured Sedentary and Physical Activity Time and Their Correlates in European Older Adults: The SITLESS Study.

BACKGROUND: Sedentary behavior (SB) and physical activity (PA) are important determinants of health in older adults. This study aimed to describe the composition of accelerometer-measured SB and PA in older adults, to explore self-reported context-specific SB, and to assess sociodemographic and functional correlates of engaging in higher levels of SB in participants of a multicenter study including four European countries. METHOD: One thousand three hundred and sixty community-dwelling older adults from the SITLESS study (61.8% women; 75.3 ±â€…6.3 years) completed a self-reported SB questionnaire and wore an ActiGraph accelerometer for 7 days. Accelerometer-determined compositional descriptive statistics were calculated. A fixed-effects regression analysis was conducted to assess the sociodemographic (country, age, sex, civil status, education, and medications) and functional (body mass index and gait speed) correlates. RESULTS: Older adults spent 78.8% of waking time in SB, 18.6% in light-intensity PA, and 2.6% in moderate-to-vigorous PA. Accelerometry showed that women engaged in more light-intensity PA and walking and men engaged in higher amounts of moderate-to-vigorous PA. Watching television and reading accounted for 47.2% of waking time. Older age, being a man, single, taking more medications, being obese and overweight, and having a slower gait speed were statistically significant correlates of more sedentary time. CONCLUSIONS: The high amount of SB of our participants justifies the need to develop and evaluate interventions to reduce sitting time. A clinically relevant change in gait speed can decrease almost 0.45 percentage points of sedentary time. The distribution of context-specific sedentary activities by country and sex showed minor differences, albeit worth noting.

Is Sedentary Behavior or Physical Activity Associated With Loneliness in Older Adults? Results of the European-Wide SITLESS Study.

Research has found that social relationships are central to the health and well-being of an aging population. Evidence exploring the association between physical activity (PA) and sedentary behavior (SB) with social isolation and loneliness is limited. This study uses objectively measured PA and SB (ActiGraph®) and self-reported measures of loneliness (the De Jong Gierveld Loneliness Scale) and social engagement (the Lubben Social Network Scale) from the SITLESS study, a European-wide study of community-dwelling older adults. Social isolation was associated with SB where higher levels of SB were associated with an increase in the level of social isolation, controlling for age, sex, living arrangements, employment status, body mass index, educational background, marital status, and self-reported general health. In contrast, PA was not associated with social isolation, and neither SB nor PA was a statistically significant predictor of loneliness. SB may be linked to social isolation in older adults, but PA and SB are not necessarily linked to loneliness in older community-dwelling adults.
