Loneliness prevalence of community-dwelling older adults and the impact of the mode of measurement, data collection, and country: A systematic review and meta-analysis.

OBJECTIVES: The aim of this systematic review and meta-analysis is to assess the prevalence of loneliness in many countries worldwide which have different ways of assessing it. DESIGN: Systematic review and meta-analysis. SETTING: We searched seven electronic databases for English peer-reviewed studies published between 1992 and 2021. PARTICIPANTS: We selected English-language peer-reviewed articles, with data from non-clinical populations of community-dwelling older adults (>60 years), and with "loneliness" or "lonely" in the title. MEASUREMENTS: A multilevel random-effects meta-analysis was used to estimate the prevalence of loneliness across studies and to pool prevalence rates for different measurement instruments, data collection methods, and countries. RESULTS: Our initial search identified 2,021 studies of which 45 (k = 101 prevalence rates) were included in the final meta-analysis. The estimated pooled prevalence rate was 31.6% (n = 168,473). Measurement instrument was a statistically significant moderator of the overall prevalence of loneliness. Loneliness prevalence was lowest for single-item questions and highest for the 20-item University of California-Los Angeles Loneliness Scale. Also, differences between modes of data collection were significant: the loneliness prevalence was significantly the highest for face-to-face data collection and the lowest for telephone and CATI data collection. Our moderator analysis to look at the country effect indicated that four of the six dimensions of Hofstede also caused a significant increase (Power Distance Index, Uncertainty Avoidance Index, Indulgence) or decrease (Individualism) in loneliness prevalence. CONCLUSIONS: This study suggests that there is high variability in loneliness prevalence rates among community-dwelling older adults, influenced by measurement instrument used, mode of data collection, and country.

Effectiveness, satisfaction and meaningfulness of a 6-step detection and prevention program for frail community-dwelling older adults: a mixed-method evaluation.

BACKGROUND: As people age, the risk of becoming frail increases, often leading to negative outcomes and less well-being. Within the light of prevention, early detection and guidance to the right care and support is crucial. This study aimed to give an overview of the descriptive results of the D-SCOPE program and evaluate the process. METHODS: The D-SCOPE program was developed as a detection and prevention program for frail community-dwelling older adults. The program creates a continuum of care and support, consisting of 6 steps: (1) Targeted case-finding using risk profiles for purposeful selection, (2) Preventive home-visit by an older volunteer, (3) Home visits by a professional, (4), Warm referral, (5) Monthly follow-up and (6) Long-term follow-up by home visit. The effectiveness of this program, in terms of satisfaction and meaningfulness, was studied quantitatively by means of a randomized controlled trial amongst 869 people with a frailty risk profile and qualitatively by 15 focus groups interviews. RESULTS: The quantitative study revealed that 83.9% of the participants found the different home visits within the D-SCOPE program useful. The focus group interviews shed light on several issues and advantages: a more efficient case finding due to the applied risk factors for frailty, a more intensive tailor-made care and support due to the warm referral, the importance of both small-scaled and larger interventions based on the wishes irrespective of the state of frailty of the older persons, the focus on a strengths-based instead of a deficit-based approach and the follow up as being one of the greatest strengths of the project. However, to fully understand the benefits of the program a shift in mind from intervention to prevention is necessary. CONCLUSIONS: Our quantitative data show that most participants found the home visits meaningful and were satisfied with the intervention. The qualitative findings provided more insights into the experiences of the participants with the process. Based on these insights of the 6-step model of preventive home visits, municipalities and organizations can apply this model to carry out more targeted home visits. TRIAL REGISTRATION: This trial was registered at ClinicalTrials.gov, on 30/05/2017, identifier: NCT03168204.

Motivators and barriers to social participation in two Chinese long-term care institutions: A focus-group study.

This study used focus group interviews with 40 older Chinese long-term care residents to explore their motivators and barriers to social participation in institutional settings informed by their lived experience. Using inductive thematic analysis, we found that motivators include pursuit of healthy ageing (better physical and mental health) and pursuit of meaningful ageing (sense of achievement and being useful, increased connectedness and realization of dreams from earlier life). The reported barriers illuminate structural components such as life-course experiences, long-term care-related barriers and Chinese policy-related barriers. The discussion highlights the importance of understanding the multidimensionality of motivators and barriers to social participation. To promote healthy ageing among institutionalized residents, staff and policy makers are recommended to initiate and support meaningful activities for residents. Residents' individual dreams and accumulated life-course disadvantages experienced long before admission to long-term care should also be considered when devising effective interventions to increase residents' level of social participation.

A search for relevant contextual factors in intervention studies: a stepwise approach with online information.

OBJECTIVE: The aim of the present study is to describe a stepwise approach to study which contextual factors might moderate the effect of healthcare interventions and to test feasibility of this approach within the D-SCOPE project. DESIGN: Exploratory case study. SETTING: In the D-SCOPE project, a complex intervention by means of home visits was set up to improve access to tailored care in three municipalities (Ghent, Knokke-Heist and Tienen). METHODS: One designed and tested an approach including five steps: (1) a theoretical/conceptual discussion of relevant contextual factor domains was held; (2) a search was done to find appropriate web-based public datasets which covered these topics with standardised information; (3) a list of all identified contextual factors was made (inventory); (4) to reduce the long list of contextual factors, a concise list of most relevant contextual factors was developed based on the opinion of two independent reviewers and (5) a nominal grouping technique (NGT) was applied. RESULTS: Three public web-based datasets were found resulting in an inventory of 157 contextual factors. After the selection by two independent reviewers, 41 contextual factors were left over and presented in a NGT which selected 10 contextual factors. The NGT included seven researchers, all familiar with the D-SCOPE intervention, with various educational backgrounds and expertise and lasted approximately 1 hour. CONCLUSION: The present study shows that a five-step approach is feasible to determine relevant contextual factors that might affect the results of an intervention study. Such information may be used to correct for in the statistical analyses and for interpretation of the outcomes of intervention studies.NCT03168204.

Gender-related differences in the relationship between social and activity participation and health and subjective well-being in later life.

A growing body of work suggests that social and activity participation (SAP) may contribute to health and well-being. Studies examining the effects of these activities largely focused on healthy older adults and older adults with more resources, not on frail older adults. On the latter, there is a lack of information about which activities contribute most and whether their effects vary between men and women given the gender-differentiated social roles. To address these gaps we extracted longitudinal data from the D-SCOPE frailty program for 380 participants aged 60 years or older residing in Belgium. Structural equation models tested the relationships between six levels of SAP based on a taxonomy of social activities (Levasseur et al., 2010) - from level 1 (for oneself) to level 6 (for others) - on longitudinal changes in physical and mental deterioration, well-being, and gender differences within these relationships. Results first show that older adults at risk of frailty benefit longitudinally from participating in activities in terms of their physical deterioration and well-being. Second, socially oriented activities were significantly associated with lower levels of physical deterioration and higher levels of subjective well-being (SWB), and volunteering with higher levels of SWB. Heterogeneity of activities, regardless of level on the taxonomy of social activities, seems to benefit SWB and counteract physical deterioration. Third, gender differences were confirmed by two activities for women (alone, task-oriented) and three activities for men (alone, being with others, task-oriented e.g. associational membership). Results imply that the activity itself may play a more important role than the nature of social involvement and social interaction in relation to health and wellbeing.

Social Participation in Older Adults after Relocation to Long-Term Care Institutions in China: A Qualitative Study.

This study used focus group interviews with older Chinese long-term care residents (N = 40), to explore their perspectives and experiences of social participation in long-term care institutions. Based on previously established taxonomy of different activity levels, we found that their social participation centered on level 3 (involvement with others), level 4 (task-oriented activities), and level 5 activities (helping others). Participants indicated that their social participation had changed after relocation. Thematic analysis revealed three main themes: increased spare time, increased presence of peers, and new participation opportunities with lost old hobbies. Focusing on the positive changes after relocation and promoting meaningful activities of different levels may benefit long-term care residents.

Social Participation in the Daily Lives of Frail Older Adults: Types of Participation and Influencing Factors.

OBJECTIVES: The advantages of social participation for older adults are well established and have been adopted in aging policy frameworks. However, little is known about the social participation of frail older adults. This research examined the types of social interaction of very frail older adults and the factors influencing this participation. METHOD: Interviews with 38 very frail older adults were analyzed using Levasseur and colleagues' (Levasseur, Richard, Gauvin, & Raymond (2010). Inventory and analysis of definitions of social participation found in the aging literature: Proposed taxonomy of social activities. Social Science and Medicine (1982), 71, 2141-2149) taxonomy activity levels of involvement with others. A qualitative hybrid approach with inductive and deductive thematic analyses was used. RESULTS: Participants often disengaged from activities with high involvement with others, preferring activities with less involvement. Low-key participation emerged as an important type of social participation enabling frail older adults to remain engaged in society. Key factors that influenced social participation were functional decline, and the physical (e.g., traffic, the disappearance of local stores) and social environment (e.g., social networks and the presence of meeting places such as community centers). DISCUSSION: Findings advance our knowledge and recognition of the different ways frail older adults participate in society. Despite their frailty, older adults wish to stay socially active. Focusing on the social environment in the frameworks and policies of Age-Friendly Cities and Communities will benefit these individuals.

Focusing on positive outcomes in frailty research: development of a short well-being instrument for older adults (SWIO).

ABSTRACTObjective:Studies of frailty have tended to focus on adverse outcomes. This study aims to develop a short instrument that identifies a positive outcome, namely, the level of well-being in older adults at risk of frailty. METHOD: 871 older adults (49.4% women; mean age 75.72 years; SD = 8.05) with a frailty risk profile participated in the first wave of the D-SCOPE study. The possible domains of well-being were identified using a bottom-up approach. Exploratory Structural Equation Modeling (ESEM) and multidimensional Item Response Theory (IRT) analysis of 17 items in 4 domains measuring well-being was performed on a calibration sample (n = 435) to develop the instrument. The instrument was subsequently corroborated by confirmatory factor analysis and convergent/divergent relations with relevant external measures in a validation sample (n = 436). RESULTS: The ESEM three-factor solution, with the subdimensions of sense of mastery, meaning in life, and life satisfaction, displayed good fit to the data (RMSEA = 0.070). For each dimension, the three best discriminating items were retained for the instrument following IRT analysis. Internal consistency of these dimensions was good in the validation sample (sense of mastery α = 0.864, meaning in life α = 0.715, and life satisfaction α = 0.782). The confirmatory factor analysis (CFA) three-factor model also showed good fit to the data (RMSEA = 0.064). Small to large zero-order correlations with the external measures were as expected. CONCLUSIONS: Using a bottom-up approach, this study developed a short instrument to identify levels of well-being in vulnerable or frail older adults. The instrument can be applied in primary care and prevention programs.

The Social Environment's Relationship With Frailty: Evidence From Existing Studies.

Increasingly, policymakers assume that informal networks will provide care for frail older people. While the literature has mainly discussed the role of the family, broader social networks are also considered to be important. However, these social networks can diminish in later life. This systematic review investigates whether the social environment increases the risk of frailty or helps to prevent it. Findings from 15 original studies were classified using five different factors, which denoted five dimensions of the social environment: (a) social networks, (b) social support, (c) social participation, (d) subjective neighborhood experience, and (e) socioeconomic neighborhood characteristics. The discussion highlights that the social environment and frailty are indeed related, and how the neighborhood dimensions and social participation had more consistent results than social support and social networks. Conclusively, recommendations are formulated to contemplate all dimensions of the social environment for further research examining frailty and community care.

Interventions for frail community-dwelling older adults have no significant effect on adverse outcomes: a systematic review and meta-analysis.

BACKGROUND: According to some studies, interventions can prevent or delay frailty, but their effect in preventing adverse outcomes in frail community-dwelling older people is unclear. The aim is to investigate the effect of an intervention on adverse outcomes in frail older adults. METHODS: A systematic review and meta-analysis of Medline, Embase, the Cochrane Library, and Social Sciences Citation Index. Randomized controlled studies that aimed to treat frail community-dwelling older adults, were included. The outcomes were mortality, hospitalization, formal health costs, accidental falls, and institutionalization. Several sub-analyses were performed (duration of intervention, average age, dimension, recruitment). RESULTS: Twenty-five articles (16 original studies) were included. Six types of interventions were found. The pooled odds ratios (OR) for mortality when allocated in the experimental group were 0.99 [95% CI: 0.79, 1.25] for case management and 0.78 [95% CI: 0.41, 1.45] for provision information intervention. For institutionalization, the pooled OR with case management was 0.92 [95% CI: 0.63, 1.32], and the pooled OR for information provision intervention was 1.53 [95% CI: 0.64, 3.65]. The pooled OR for hospitalization when allocated in the experimental group was 1.13 [95% CI: 0.95, 1.35] for case management. Further sub-analyses did not yield any significant findings. CONCLUSION: This systematic review and meta-analysis does not provide sufficient scientific evidence that interventions by frail older adults can be protective against the included adverse outcomes. A sub-analysis for some variables yielded no significant effects, although some findings suggested a decrease in adverse outcomes. TRIAL REGISTRATION: Prospero registration CRD42016035429 .

Randomized controlled trial to evaluate a prevention program for frail community-dwelling older adults: a D-SCOPE protocol.

BACKGROUND: Frail community-dwelling older adults, whom might experience problems regarding physical, cognitive, psychological, social and environmental factors, are at risk for adverse outcomes such as disability, institutionalization and mortality. People in need of help do not always find their way to care and support services and are left undetected. The aim of the D-SCOPE project is to detect frail community-dwelling older adults who previously went unnoticed and to improve their access to care and support. Goal is to increase their frailty-balance, quality of life, meaning in life, life satisfaction, mastery, community inclusion and ageing well in place. METHODS/DESIGN: The study is a prospective, longitudinal randomized four-armed controlled trial with follow-up at 6 months. The study group aims to include 900 community-dwelling older adults aged 60 years and over from 3 municipalities in Flanders (Belgium). While selecting the study group, risk profiles for frailty will be taken into account. Participants will be randomly selected from the census records in each municipality. Data will be collected prospectively at baseline (T0) and at follow-up, 6 months after baseline (T1). At baseline, participants who are at least mild frail on one of the 5 domains of frailty (CFAI-plus) or feel frail based on the subjective assessment of frailty will be randomly assigned to (1) the study group or (2) the control group. A mixed method design with the inclusion of quantitative and qualitative data analyses will be used to evaluate the efficacy and experiences of the detection and prevention program on frailty. DISCUSSION: The study will contribute to an innovative vision concerning the organization of care and support, and a timely and accurate detection and support of community-dwelling older adults at risk for frailty. TRIAL REGISTRATION: This trial was registered at ClinicalTrials.gov, on May 26, 2017, identifier: NCT03168204 .

Detecting frail, older adults and identifying their strengths: results of a mixed-methods study.

BACKGROUND: The debate on frailty in later life focuses primarily on deficits and their associations with adverse (health) outcomes. In addition to deficits, it may also be important to consider the abilities and resources of older adults. This study was designed to gain insights into the lived experiences of frailty among older adults to determine which strengths can balance the deficits that affect frailty. METHODS: Data from 121 potentially frail community-dwelling older adults in Flemish-speaking Region of Belgium and Brussels were collected using a mixed-methods approach. Quantitative data were collected using the Comprehensive Frailty Assessment Instrument (CFAI), Montreal Cognitive Assessment (MoCA), and numeric rating scales (NRS) for quality of life (QoL), care and support, meaning in life, and mastery. Bivariate analyses, paired samples t-tests and means were performed. Qualitative data on experiences of frailty, frailty balance, QoL, care and support, meaning in life, and mastery were collected using semi-structured interviews. Interviews were subjected to thematic content analysis. RESULTS: The "no to mild frailty" group had higher QoL, care and support, meaning in life, and mastery scores than the "severe frailty" group. Nevertheless, qualitative results indicate that, despite being classified as frail, many older adults experienced high levels of QoL, care and support, meaning in life, and mastery. Respondents mentioned multiple balancing factors for frailty, comprising individual-level circumstances (e.g., personality traits, coping strategies, resilience), environmental influences (e.g., caregivers, neighborhood, social participation), and macro-level features (e.g., health literacy, adequate financial compensation). Respondents also highlighted that life changes affected their frailty balance, including changes in health, finances, personal relationships, and living situation. CONCLUSION: The findings indicate that frailty among older individuals can be considered as a dynamic state and, regardless of frailty, balancing factors are important in maintaining a good QoL. The study investigated not only the deficits, but also the abilities, and resources of frail, older adults. Public policymakers and healthcare organizations are encouraged to include these abilities, supplementary or even complementary to the usual focus on deficits.

Correction: Limitations in Activities of Daily Living in Community-Dwelling People Aged 75 and Over: A Systematic Literature Review of Risk and Protective Factors.

Identifying frailty risk profiles of home-dwelling older people: focus on sociodemographic and socioeconomic characteristics.

OBJECTIVES: This paper investigates risk profiles of frailty among older people, as these are essential for detecting those individuals at risk for adverse outcomes and to undertake specific preventive actions. Frailty is not only a physical problem, but also refers to emotional, social, and environmental hazards. METHODS: Using data generated from the Belgian Ageing Studies, a cross-sectional study (n = 28,049), we tested a multivariate regression model that included sociodemographic and socioeconomic indicators as well as four dimensions of frailty, for men and women separately. RESULTS: The findings indicated that for both men and women, increased age, having no partner, having moved house in the previous 10 years, having a lower educational level and having a lower household income are risk characteristics for frailty. Moreover, when looking at the different frailty domains, different risk profiles arose, and gender-specific risk characteristics were detected. DISCUSSION: This paper elaborates on practical implications, and formulates a number of future research recommendations to tackle frailty in an aging society. The conclusion demonstrates the necessity for a thorough knowledge of risk profiles of frailty, as this will save both time and money and permit preventive actions to be more individually tailored.

Limitations in Activities of Daily Living in Community-Dwelling People Aged 75 and Over: A Systematic Literature Review of Risk and Protective Factors.

BACKGROUND: Most older people wish to age in place, for which functional status or being able to perform activities of daily living (ADLs) is an important precondition. However, along with the substantial growth of the (oldest) old, the number of people who develop limitations in ADLs or have functional decline dramatically increases in this part of the population. Therefore, it is important to gain insight into factors that can contribute to developing intervention strategies at older ages. As a first step, this systematic review was conducted to identify risk and protective factors as predictors for developing limitations in ADLs in community-dwelling people aged 75 and over. METHODS: Four electronic databases (CINAHL (EBSCO), EMBASE, PsycINFO and PubMed) were searched systematically for potentially relevant studies published between January 1998 and March 2016. RESULTS: After a careful selection process, 6,910 studies were identified and 25 were included. By far most factors were examined in one study only, and most were considered risk factors. Several factors do not seem to be able to predict the development of limitations in ADLs in people aged 75 years and over, and for some factors ambiguous associations were found. The following risk factors were found in at least two studies: higher age, female gender, diabetes, hypertension, and stroke. A high level of physical activity and being married were protective in multiple studies. Notwithstanding the fact that research in people aged 65 years and over is more extensive, risk and protective factors seem to differ between the 'younger' and 'older' olds. CONCLUSION: Only a few risk and protective factors in community-dwelling people aged 75 years and over have been analysed in multiple studies. However, the identified factors could serve both detection and prevention purposes, and implications for future research are given as well.
