Home care and quality of life among community-dwelling dependent older adults in Israel: a multiple mediator model.

PURPOSE: To examine the association between home care provision (combined paid formal home care and non-paid family-only home care) versus non-paid family-only home care with quality of life (QoL) of older adults, as well as the mediating effects of loneliness, social isolation and satisfaction with family relationships and support. METHODS: A convenience sample of 360 Israeli dependent adults aged 65 + responded to questionnaires. Using bootstrapping, we tested the strength and significance of the conditional indirect effects of the four simultaneous mediators. RESULTS: Using combined home care provision (paid formal home care and non-paid family-only home care) versus non-paid family-only home care for older adults was associated with lower QoL of care-recipients (B = - 4.57, t = - 2.24, p = 0.001, 95% CI - 8.58, - 0.56; R2 = 0.37), and was fully and strongly mediated by feelings of loneliness (B = - 1.92, p = 0.001, 95% CI - 3.66, - 0.79), social isolation (B = - 0.54, p = 0.001, 95% CI - 1.47, - 0.07) and satisfaction with family support (B = - 1.09, p = 0.001, 95% CI - 2.57, - 0.16). However, the indirect effect through satisfaction with family relationships was not significant. The highest proportion of the indirect effect size was (B = 0.42, 95% CI 0.13, 1.97) for loneliness, followed by satisfaction with family support (B = 0.23, 95% CI 0.01, 1.07), and social isolation (B = 0.11, 95% CI 0.01, 0.66), respectively. CONCLUSIONS: Using combined formal home care might reduce the QoL of care-recipients by increasing their feelings of loneliness, social isolation and reduced perceived family support. Practitioners should encourage family members to continue with family regular support and contact alongside the use of formal home care in order to maintain satisfaction and QoL of older relatives.

The Protective Role of Group Activity Prior to COVID-19 Pandemic Quarantine on the Relation between Loneliness and Quality of Life during COVID-19 Pandemic.

BACKGROUND: Studies of aging have suggested that QoL is positively associated with active social contacts and supportive face to face social networks. However, social networks and contacts in later life decrease due to a variety of reasons; the narrowing of social networks contributes to increased social isolation and loneliness and leads to the deterioration of well-being and QoL among adult persons. The goal of this study was to explore the relationship between loneliness feelings and QoL during the COVID-19 quarantine as potentially moderated by group physical activity prior to the COVID-19 pandemic quarantine. METHODS: A convenience sample of 99 older adults aged 60 and over was interviewed. Using bootstrapping, we tested the strength and significance of the conditional moderation effect of group physical activity prior to the COVID-19 pandemic quarantine on the relationship between loneliness feelings and QoL during the COVID-19 quarantine. RESULTS: the results demonstrated a direct negative effect between loneliness feelings and QoL during the COVID-19 pandemic and that the relationship was moderated by group physical activity prior to the COVID-19 pandemic quarantine (p = 0.000). CONCLUSION: the findings indicate that policy makers and professionals working with older adults should seek ways to attract older adults to participate in group physical activity and enjoy its long-term social benefits.

A personalized diet intervention improves depression symptoms and changes microbiota and metabolite profiles among community-dwelling older adults.

Introduction: The impact of diet on mental well-being and gut microorganisms in humans is well recognized. However, research on the connections between food nutrients, gut microbiota, and mental health remains limited. To address this, the present study aimed to assess the effects of a personalized diet, based on individual needs and aligned with the Mediterranean diet principles, on depression symptoms, quality of life, nutritional intake, and gut microbiota changes among older adults living in the community. Methods: The intervention involved regular visits from a registered dietitian, who provided tailored dietary recommendations. During the 6-month study, participants completed questionnaires to evaluate their depression levels, quality of life, and dietary habits. Additionally, they provided stool samples for analysis of gut microbiota and metabolites. Results: The results demonstrated that the personalized dietary intervention reduced depression symptoms and improved the quality of life among older adults. Furthermore, significant changes in the intake of certain nutrients, such as folate, lutein, zeaxanthin, EPA, and DHA, were observed following the intervention. Moreover, the intervention was associated with increased diversity in the gut microbiome and reduced total short-chain fatty acids, the main metabolites produced by gut microorganisms. The study also revealed correlations between food nutrients, gut microbiota, and mental health parameters. Discussion: In conclusion, this research highlights the potential advantages of personalized dietary interventions in managing depression and enhancing overall well-being among older populations. It also sheds light on the role of gut microbiota and its metabolites in these effects. The findings offer valuable insights into the significance of nutrition and gut health for mental well-being in older adults.

Utilization of ADCCs and quality of life among older adults: ethno-regional disparities in Israel.

BACKGROUND: Adult day care centers (ADCCs) are a common service provided for frail older adults in the community. We examined the influence of older adults' utilization of ADCC's on their quality of life (QoL), and whether ethno-regional disparities are factors in the gaps found concerning QoL in different regions and between different ethnic groups. METHODS: Cross sectional data were collected through structured interviews with 360 older adults attending ADCCs. Participants represented three ethnic groups and three regions in Israel. QoL was assessed by SF-36 questionnaire. RESULTS: The results revealed a positive correlation between weekly hours at the ADCC, satisfaction with attending ADCC, and QoL. Older adults living in the central region had higher QoL than those living in the southern and northern regions. Veteran Israeli Jews reported higher QoL than FSU immigrants Israeli Arabs in all regions. Connection to one's residential area was also correlated with QoL. A significant moderating effect of the interaction (ethnicity*area of residence) on QoL was also revealed. CONCLUSIONS: Attending ADCC is a vital community services to promote QoL in later life. Gaps in ADCC utilization between ethnic groups and residential region may cause disparities in QoL, specifically, in minority groups and those living in peripheral regions. Service providers should minimize the disparities by improving accessibility and availability for each person regardless of ethnicity and region of residence.

Physical distancing is related to fewer electronic and in-person contacts and to increased loneliness during the COVID-19 pandemic among older Europeans.

PURPOSE: During the COVID-19 pandemic older adults are asked to maintain physical distancing, which can be linked to loneliness. While older people are encouraged to use electronic communication to stay socially connected, it remains an open question whether electronic contacts are related to lower loneliness during the pandemic. This study examined the associations of physical distancing during the pandemic with loneliness and the role of in-person and electronic contacts with children and non-kin as explaining these associations across European regions. METHODS: The study used data from Survey of Health, Ageing and Retirement in Europe (SHARE), collected during the COVID-19 pandemic in 2020. Mediation and moderation analyses tested the direct and indirect associations between physical distancing, contact frequency and loneliness, as well as the differences across European regions. RESULTS: The results indicate that adults who reported higher frequency of physical distancing also felt lonelier during the pandemic. This association was partly explained by social contacts-those who practiced physical distancing maintained less in-person contact with children and non-kin and less electronic contact with non-kin, which were related to feeling lonelier. Adults in Southern European countries felt lonelier and reported more frequent contacts. The moderation analyses showed that the link between physical distancing and loneliness was found in the northern region, but not in the southern and eastern regions of Europe. CONCLUSION: This study can indicate that attention should be paid to adults who may struggle to maintain social contacts in light of physical distancing guidelines.

A prospective association between tooth status and cognitive performance among older adults in Europe.

OBJECTIVES: This study set out to examine both the longitudinal association between tooth status and cognitive performance among older adults in Europe, and the mediating effects of loneliness and quality of life on this association. METHODS: We conducted a prospective analysis using data from 38,614 participants aged 50 or older, taken from the Survey of Health, Ageing and Retirement in Europe (SHARE) of 2013 (baseline) and 2015 (follow up). Bootstrapping with resampling strategies was used for testing a multiple mediator model. RESULTS: The average age of participants was 66.9 (SD = 9.4). About 23% of the participants had full sets of their own teeth and 38.2% had missing teeth fully replaced by dental implants or dentures. Participants who had partially replaced teeth (B = 0.038, p < 0.001), and with fully replaced teeth (B = 0.041, p < 0.001), or had all their teeth in place (B = 0.055, p < 0.001), had better cognitive performance compared to those who did not replace their missing teeth. It was also found that quality of life and loneliness partially mediated these relationships - Having all teeth in place or replacing all or partially missing teeth was found to affect cognitive performance also via improved quality of life and through lower loneliness. CONCLUSION: In later life, poor tooth status can be directly associated with cognitive decline and indirectly linked to cognitive performance, in light of decreasing quality of life and increasing loneliness. Clinicians should be aware of both the impact of poor tooth status on cognitive status and the implications for the wellbeing of older adults.

Social support and loneliness among frail older adults attending daycare centers: A multicultural study in Israel.

AIMS: To examine the link between intensity of use of formal support and loneliness among older adults, controlling for family support and covariates; and examine the moderating effect of contact frequency with family on this relationship. METHODS: Cross-sectional data were collected from September 2016 - April 2017 through structured interviews with 360 older adults attending adult day care centers (ADCCs) and representing three different ethnic groups in Israel. Loneliness was assessed by the UCLA Loneliness Scale. Hierarchical regression was applied to the study variables with loneliness scores as dependent variable, and bootstrapping with resampling strategies tested a moderating effect. RESULTS: Loneliness was linked negatively with contact frequency with the family network, frequency of ADCC attendance, and greater involvement in social activities at the ADCC. Significant negative correlation between ADCC attendance frequency and loneliness occurred only when family contact was at low-to-average frequency, but not in cases of high-contact frequency. CONCLUSIONS: Frequent use of ADCCs emerged as a significant contributor beyond the contribution of family support for reducing loneliness in older age, particularly for those with insufficient family contact. Service providers should improve the accessibility and availability of formal community services for the older population.

Loneliness, Malnutrition and Change in Subjective Age among Older Adults during COVID-19 Pandemic.

Objectives: We examined the effect of loneliness and the role of two mediating factors, depressive symptoms and malnutrition on subjective age among older adults during the 2020 COVID-19 pandemic, and explored how the pandemic is affecting subjective age. Design: A convenience sample of 201 older adults aged 65 and over was interviewed. Using bootstrapping, we tested the strength and significance of the indirect effect of depressive symptoms and malnutrition (mediators) on the relationship between feelings of loneliness and subjective age. Results: The relationship between feelings of loneliness and subjective age during the COVID-19 pandemic was mediated by malnutrition, but not by depressive symptoms. In addition, the participants felt older during the COVID-19 pandemic compared with the preceding period. Conclusions: An association was found among feelings of loneliness, malnutrition, and subjective age. To overcome these feelings in times of crisis like the pandemic, it is essential to develop new communication methods (technologies for managing and addressing the needs of the older population; technologies to encourage social engagement, and technologies for managing and providing remote medical services) for and with older adults that are effective in reducing loneliness, and to promote good nutrition. Possible practical solutions include new social network technologies for reducing loneliness combined with continued reliance on phone communication as an intervention of psychological support to promote a healthy lifestyle and prevent malnutrition.

Perceived Accessibility to Services and Sites Among Israeli Older Adults.

OBJECTIVE: To explore the direct and indirect effects of settlement type (rural-kibbutz vs. urban mid-size cities) on perceived accessibility by sociospatial factors: (a) connection to the living area, (b) familiarity with the living area, (c) social participation, and (d) perceived safety of the living area. METHOD: A convenience sample of 279 older adults aged 65 and older was interviewed. Using bootstrapping, we tested the strength and significance of the conditional indirect effects of four simultaneous mediators of the relationship between settlement type and perceived accessibility. MAIN FINDINGS: The relationship between settlement type and perceived accessibility was mediated by social participation and perceived safety of the living area. CONCLUSION: Policy makers should pay attention to the enhancement of sociospatial dimensions to improve the perceived accessibility of older adults.

Aging in place and quality of life among the elderly in Europe: A moderated mediation model.

OBJECTIVES: We explored the moderated-mediation effects of perceived accessibility to the environment on quality of life in later life via two socio-spatial mediators (loneliness and connection to place) and two moderators (functional disability and marital status). METHODS: We utilized the data of the fifth wave of the Survey of Health, Aging and Retirement in Europe (SHARE) to analyze the quality of life of 13,828 Europeans aged 65 or older. Bootstrapping with resampling strategies was used to test the moderated-mediation hypotheses. RESULTS: Higher scores for perceived accessibility to services and sites was associated with greater quality of life. This relationship was partially mediated by lower loneliness and higher connection to place, and moderated by functional disability and marital status. DISCUSSION: Policymakers and planners should plan suitable, accessible and age-friendly social and spatial environments for dependent and independent older adults. They should also suggest interventions to mitigate social loneliness and modify spatial obstacles.

Internet use, social networks, loneliness, and quality of life among adults aged 50 and older: mediating and moderating effects.

BACKGROUND: The increase in longevity of people on one hand, and on the other hand the fact that the social networks in later life become increasingly narrower, highlights the importance of Internet use to enhance quality of life (QoL). However, whether Internet use increases or decreases social networks, loneliness, and quality of life is not clear-cut. PURPOSES: To explore the direct and/or indirect effects of Internet use on QoL, and to examine whether ethnicity and time the elderly spent with family moderate the mediation effect of Internet use on quality of life throughout loneliness. METHODS: This descriptive-correlational study was carried out in 2016 by structured interviews with a convenience sample of 502 respondents aged 50 and older, living in northern Israel. Bootstrapping with resampling strategies was used for testing mediation a model. RESULTS: Use of the Internet was found to be positively associated with QoL. However, this relationship was mediated by loneliness, and moderated by the time the elderly spent with family members. In addition, respondents' ethnicity significantly moderated the mediation effect between Internet use and loneliness. CONCLUSIONS: Internet use can enhance QoL of older adults directly or indirectly by reducing loneliness. However, these effects are conditional on other variables. The indirect effect moderated by ethnicity, and the direct effect moderated by the time the elderly spend with their families. Researchers and practitioners should be aware of these interactions which can impact loneliness and quality of life of older persons differently.
