Association of frailty with workplace social activity, physical activity, and well-being among older employees: a moderated mediation in two income-variant samples.

BACKGROUND: Research suggests that frailty is associated with lower physical activity and well-being in old age, but social activities at work may facilitate physical activity and its positive effect on well-being among older employees with frailty. This study, therefore, ascertained whether there is a moderated mediation of the association of frailty, Workplace Social Activity (WSA), and well-being by Physical Activity (PA). METHODS: The study adopted a cross-sectional design with relevant sensitivity analyses for confounding. The participants were within two Ghanaian samples with different income levels (low-income, n = 897, and higher income, n = 530). The minimum samples were calculated, and the statistical models were tested with Haye's Process Model through structural equation modelling. RESULTS: Frailty was negatively associated with PA, and this relationship was moderated by WSA in both samples. Higher frailty was directly and indirectly associated with lower well-being in the higher-income sample but only indirectly associated with lower well-being in the low-income sample. The mediation of PA in the frailty-well-being relationship is partial in the higher-income sample but complete in the low-income sample. There was evidence of moderated mediation in both samples. CONCLUSION: WSA may reduce the strength of the negative association of frailty with PA and well-being among older employees in both samples. Workplace interventions aimed at enhancing WSA may encourage PA and enhance well-being among older employees with frailty.

Association of increased participation in social activity in later life with risk of all-cause mortality and heart diseases in older people: results from the Chinese Longitudinal Healthy Longevity Survey (CLHLS).

Background: Previous studies have shown social activity is associated with reduced risk of health outcomes. However, among older people (≥65 years) who were socially inactive at baseline, limited study explored whether increased participation in social activity in later life was associated with reduced risk of health outcomes; therefore, using the data from the Chinese Longitudinal Healthy Longevity Survey, the study was performed. Methods: The study outcomes were 10-year all-cause mortality (sample number = 9,984) and 10-year heart diseases (sample number = 7,496). The exposure was the change of social activity frequency. Cox regression analysis was used for data analysis. Results: During the follow-up, there were 6,407 all-cause mortalities and 1,035 heart diseases, respectively. Kaplan-Meier analysis demonstrated that cumulative incidences of all-cause mortality were significantly lower in participants with changes into more frequent social activity (log-rank p < 0.001), while no significant difference was observed for heart diseases (log-rank p = 0.330). Compared with the subgroup who never participated in social activity at baseline, adjusted HRs of all-cause mortality were 0.79 (95% CI: 0.70-0.90, p < 0.001), 0.78 (95% CI: 0.63-0.96, p = 0.019), 0.74 (0.59-0.92, p = 0.006), and 0.70 (95% CI: 0.56-0.88, p = 0.002) for the subgroup of switching to sometimes, the subgroup of switching to once a month, the subgroup of switching to once a week, and the subgroup of switching to everyday, respectively. The corresponding HRs of heart diseases were 0.83 (95% CI: 0.65-1.08, p = 0.170), 0.82 (95% CI: 0.51-1.31, p = 0.412), 0.91 (0.58-1.42, p = 0.675) and 0.75 (95% CI: 0.47-1.20, p = 0.227), respectively. Stratified and sensitivity analyses revealed similar results. Conclusion: Among older people who never participated in social activity, increased participation in social activity in later life was associated with reduced risk of all-cause mortality, but was not associated with reduced risk of heart diseases.

Social activities and depressive symptoms among migrant middle-aged and older adults in China: a network analysis.

Background: This study investigated the central symptom within the depression network and examined the relationship between social activities and depressive symptoms among migrant middle-aged and older adults in China. Methods: We analyzed data from 1,926 migrants aged 45 and older, derived from the 2018 China Health and Retirement Longitudinal Study (CHARLS). Using network analysis, we identified the central depressive symptom and assessed the association between various social activities and depressive symptoms. Results: Network analysis revealed that depressed mood was the most central symptom. Regarding mitigation of depressive symptoms, informal social activities predominantly influenced positive emotions and somatic symptoms. Formal activities were mainly revealed through positive emotions. Solitary activities were manifested primarily through positive emotions and somatic symptoms. In addition, informal and solitary activities showed a stronger correlation with the alleviation of depressive symptoms compared to formal activities. Conclusion: The findings underscore the importance of addressing depressed mood in treating depression among migrant middle-aged and older adults. Recognizing the differential impacts of various social activities can aid in the development of customized prevention and intervention strategies aimed at enhancing the mental well-being of this demographic in China.

Effect of Early Rehabilitation Services After Discharge on Social Activity Among Chronic Stroke Survivors: A Multicenter Prospective Study.

BACKGROUND: Social inactivity after a stroke leads to adverse outcomes, making social activity after discharge important for chronic stroke survivors. This study aimed to investigate the effects of early rehabilitation services after discharge on social activity among chronic stroke survivors. METHODS: The participants were prospectively recruited from 3 convalescent hospitals. Receipt of early rehabilitation services after discharge for chronic stroke survivors was defined as the utilization of day care or home-based rehabilitation services by the Japanese long-term care insurance system. Social activity was assessed using the Frenchay Activities Index (FAI) premorbid and at 3, 6, and 12 months after discharge. In this study, the outcome was defined as the change in the FAI score from 3 to 12 months after discharge. Multivariate regression analysis was performed to examine the effect of access to rehabilitation on changes in FAI. RESULTS: Ninety stroke survivors (age 67.2±11.6 years, 52 male) were enrolled. The FAI showed improvements by 27.4% and 1.4% from 3 to 12 months after discharge in the rehabilitation and nonrehabilitation groups, respectively. Multivariate regression analysis showed that access to rehabilitation after discharge was positively associated with the FAI change from 3 to 12 months after discharge (B=30.3, ß=0.38, 95% confidence interval=11.13-49.47, P=0.002). CONCLUSIONS: Early rehabilitation services after discharge were significantly associated with increased social activity.

Association between perceived value of adopting new behaviors and incident disability among Japanese community-dwelling older adults.

OBJECTIVES: This longitudinal observational cohort study aimed to clarify the relationship between perceived value (PV) to adopt new behaviors and incident disability in community-dwelling older adults. METHOD: Participants were 5073 community-dwelling older adults aged ≥65 years in Japan (Mage = 74.0 ± 5.6 years; female = 55.1%). The mean follow-up time was 34.5 months. Baseline data were collected during health checkups in a prospective cohort study. Measurements included engagement in physical activity (PA), cognitive activity (CA), and social activity (SA), PV, health and physical conditions, and demographic characteristics. PV was assessed by asking whether participants thought it was valuable to adopt new behaviors related to PA, CA, and SA. Participants were classified as having higher/lower PV, PA, CA, and SA. Cox proportional hazard models were used to analyze the association between PV and incident disability. PV was examined both as an independent variable and in combination as follows: higher PV and higher PA/CA/SA (high/high); lower PV and higher PA/CA/SA (low/high); higher PV and lower PA/CA/SA (high/low); and lower PV and lower PA/CA/SA (low/low). RESULTS: Higher PV was significantly associated with a lower hazard ratio (HR) for incident disability. The low/high, high/low, and low/low significantly increased the HR compared to high/high in the analyses of PV & PA and CA. The analysis of PV & SA showed that only low/low increased the HR compared to high/high. CONCLUSION: Having both higher PV and higher activity engagement may contribute to preventing disability development. Both support for activities and value education in older adults may be needed.

The association between intolerance of uncertainty and depressive symptoms during COVID-19 in New York, USA.

BACKGROUND: Coronavirus Disease 2019 (COVID-19), a highly contagious respiratory illnesses, has globally impacted mental health. This study aims to investigate the association between intolerance of uncertainty and depressive symptoms during the pandemic in New York, USA, considering COVID-19-related worries as modifiers and mediators. METHOD: 1227 participants from three ongoing cohort studies, originally centered on trauma-exposed children and adolescents, provided data via questionnaires and telephone interviews across three waves. We used multivariable logistic and linear regression models to investigate the intolerance of uncertainty-depressive symptoms relationship, while adjusting for potential confounders and assessing the modification and mediation effects of Covid-19 related worries. RESULTS: Depressive symptoms prevalence was 18 %, 12 %, and 9 % at waves 0, 1, and 2 respectively. Strong positive associations were observed between intolerance of uncertainty above the median and depressive symptoms which remained significant after adjusting for potential confounders. Odds ratios were 2.14 (95 % CI: 1.54-2.99) and 4.50 (95 % CI: 2.67-7.93) for intolerance of uncertainty-depressive symptoms association at wave 0 and 1 respectively, and 3.22 (95 % CI: 1.68-6.63) for intolerance of uncertainty at wave 1 and depressive symptoms at wave 2. There was evidence of partial mediation by worries (12-37 %), but no evidence of a moderating effect. LIMITATION: It includes study's methodology, including self-report measures, remote data collection, and uncontrolled variables like anxiety and COVID-19 perspectives. CONCLUSION: The findings emphasize the importance of evidence-based strategies for tackling intolerance of uncertainty during pandemics, particularly in managing long COVID. Collaborative efforts between policymakers and clinicians are essential in this endeavor.

Factors associated with social participation among community-dwelling frail older adults in Japan: a cross-sectional study.

BACKGROUND: In recent years, it has become clear that participation in social activities by the older adult suppresses their need for long-term care. Likewise, social participation can promote long-term care prevention among frail older adults who are at a higher risk of needing long-term care. However, their social participation rate is low, and the factors causing these low rates of participation are unclear. Therefore, this study identifies the factors affecting social participation of frail older adults. METHODS: After excluding those certified as requiring long-term care, 28,636 older adults within the target region were selected to receive questionnaires. The questionnaires were distributed and collected via mail. A total of 22,048 respondents (77.0%), including 9,325 men and 10,150 women, were included; 2,655 frail older adults were identified for analysis. Questionnaire items inquired about social participation, basic attributes, need for long-term care, mobility, subjective health, direct and indirect contact with relatives living separately and direct and indirect contact with friends and neighbors. For the statistical analysis, this study employed a binomial logistic regression analysis with social participation as the objective variable. RESULTS: The rate of social participation among frail older adults was 13.7%. Items related to social participation included sex, economic status, mobility, subjective health, direct contact with friends, and indirect contact with friends. CONCLUSIONS: Interactions with friends and neighbors and physical functionality are correlated with levels of social participation among frail older adults, suggesting that social participation can be promoted by maintaining friendships, forming new ones, and maintaining and improving physical functionality.

Development of a weighted scoring model for social activities to predict disability incidents among older Japanese adults.

BACKGROUND: Social activities contribute to health improvements in older adults, but methods for evaluating these activities are not yet established. We developed a scoring model for social activity, weighted by specific activities, to assess the association between disability incidence in older adults and social activities. METHODS: Data were obtained from Japan's National Center for Geriatrics and Gerontology Study of Geriatric Syndromes (NCGG-SGS). Social activity was evaluated across 16 domains. Disability was determined using data extracted from Japan's long-term care insurance system. RESULTS: Data from 4998 older adults were analyzed; among them, 422 (8.4 %) developed a disability within 35 months (Interquartile range: 32-39). The Cox proportional hazards model was used to assess 16 domains of social activity. The results yielded risk factors for disability incidence in six social activity domains: work, travel, hobbies, babysitting, family caregiving, and events. The coefficients for these activities were assigned weights of 3, 3, 2, 1, 1, and 1, respectively. The weighted social activity scoring model significantly improved the ability to predict disability incidence when the number of social activities in which individuals participated was considered (social activity score: area under the curve [AUC] 0.691, 95 % confidence interval [CI] 0.664-0.717; number of social activities: AUC 0.681, 95 % CI 0.654-0.707, P = 0.042). CONCLUSIONS: The composite score derived from the weighted social activity scoring model serves as a valuable tool due to its enhanced predictability, which complements established background factors associated with the incidence of disability in older adults.

Social participation mediates the relationship between self-efficacy and loneliness among people with stroke during COVID-19: a cross-sectional study.

BACKGROUND: People post-stroke experience increased loneliness, compared to their healthy peers and loneliness may have increased during COVID due to social distancing. How social distancing affected loneliness among people after stroke is unknown. Bandura's self-efficacy theory suggests that self-efficacy may be a critical component affecting individuals' emotions, behaviors, attitudes, and interpretation of everyday situations. Additionally, previous studies indicate that self-efficacy is associated with both loneliness and social participation. This study investigates relationships among self-efficacy, social participation, and loneliness in people with stroke. OBJECTIVES: Determine how social participation affects the relationship between self-efficacy and loneliness in people with stroke during the COVID-19 pandemic. METHODS: 44 participants were community-dwelling individuals, ≥ 6 months post-stroke who participated in a 2-hour phone interview. A regression-based mediation analysis was conducted using these measures: Participation Strategies Self-Efficacy Scale, Activity Card Sort for social participation, and UCLA Loneliness Scale for loneliness. RESULTS: The total effect of self-efficacy on loneliness was significant (b = -0.36, p = .01). However, social participation fully mediated the relationship between self-efficacy and loneliness (indirect effect, b = -0.11, 95% CI [-0.24, -0.01]; direct effect, b = -0.25, 95% CI [-0.03, 0]). CONCLUSIONS: Self-efficacy is associated with both social participation and loneliness in people with stroke in this cross-sectional study. Mediation analysis findings suggest that interventions focused on increasing social participation may prevent or potentially alleviate loneliness in people with stroke who have low self-efficacy.

Psychometric properties of a Turkish version of the social activities scale for community-dwelling older people requiring support.

BACKGROUND: Social activities decelerate the deterioration of mental capacity in older people and improve their physical and psychosocial health. Valid and reliable measurement tools are needed to determine the social activity status of older people and plan health services to protect their mental health. OBJECTIVE: This study aimed to adapt the Social Activities Scale for Community-Dwelling Older People Requiring Support (SASOS) into Turkish. METHODS: This methodological study was conducted in Northern Cyprus between January and June 2022. Convenience sampling was used to recruit 155 community-dwelling older people who needed support. Expert opinion, item-content validity index, and scale-content validity index were used to evaluate content validity. Internal consistency and test-retest reliability tests were used to evaluate reliability. Exploratory factor analysis was used to evaluate construct validity. The Loneliness Scale for Elderly was used to evaluate concurrent validity. RESULTS: The Cronbach's alpha of SASOS was 0.90. Additionally, correlation coefficients of all items ranged between 0.61 and 0.79. Exploratory factor analysis revealed a three-factor structure. 'Interactions with friends and neighbors' was the factor that explained the highest variance (46%). There was a negative, weak, and statistically significant relationship between the scores obtained from the social loneliness subscale of LSE and all three subscales of SASOS. CONCLUSIONS: The Turkish version of SASOS is a valid, reliable instrument to evaluate social activities in community-dwelling older people who needed support. IMPLICATIONS FOR PRACTICE: The SASOS has been identified as a valuable measure for assessing the social support needs of older individuals. It serves as a guide for both planning and evaluating interventions to enhance their health.

The link between disability and social participation revisited: Heterogeneity by type of social participation and by socioeconomic status.

BACKGROUND: While prior literature explores the impact of disability on social participation, the distinct characteristics of diverse social activities could further complicate this relationship. Furthermore, this relationship may exhibit heterogeneity when considering socioeconomic status (SES). OBJECTIVE: This study aims to investigate whether the relationship between disability and social participation differs depending on the type of social participation, and to what extent this relationship is moderated by SES. METHODS: Data from seven waves of the Korean Longitudinal Study of Ageing were analyzed. Various types of social participation, including socializing, leisure, volunteer, political, and religious activities, were considered. Individual fixed effects models were employed to account for unobserved individual-level heterogeneity. To investigate the potential moderating role of SES, an interaction term between disability and SES was included. RESULTS: Disability was associated with a decrease in social participation (b = -0.088). When differentiating types of social participation, the associations were negative for socializing and leisure activities (b = -0.092 and b = -0.012, respectively) and positive for volunteer activities (b = 0.012). The negative association between disability and social participation was generally stronger among higher-SES groups than lower-SES groups. Specifically, the negative association with leisure activities was more pronounced among the high-education groups. In contrast, the positive association with volunteer activities was more evident among the low-education group. CONCLUSIONS: Disability has a negative association with engagement in socializing and leisure activities and a positive association with engagement in volunteer activities. Policymakers should consider the role of SES in complicating the relationship between disability and social participation.

Multimodal lifestyle engagement patterns support cognitive stability beyond neuropathological burden.

BACKGROUND: Modifiable lifestyle behaviors account for a large proportion of dementia risk. However, the combined contributions of multidomain lifestyle patterns to cognitive aging are poorly understood, as most studies have examined individual lifestyle behaviors in isolation and without neuropathological characterization. This study examined data-driven patterns of lifestyle behaviors across multiple domains among older adults and tested their associations with disease-specific neuropathological burden and cognitive decline. METHODS: Participants included 2059 older adults enrolled in the longitudinal Memory and Aging Project (MAP) at the Rush Alzheimer's Disease Center; none of whom had dementia at baseline (73% no cognitive impairment (NCI), 27% mild cognitive impairment [MCI]). All participants completed cognitive testing annually. Lifestyle factors were measured during at least one visit and included (1) actigraphy-measured physical activity, as well as self-reported (2) sleep quality, (3) life space, (4) cognitive activities, (5) social activities, and (6) social network. A subset of participants (n = 791) had autopsy data for which burden of Alzheimer's disease (AD), cerebrovascular disease (CVD), Lewy body disease, and hippocampal sclerosis/TDP-43 was measured. Latent profile analysis across all 2059 participants identified distinct subgroups (i.e., classes) of lifestyle patterns. Linear mixed-effects models examined relationships between lifestyle classes and global cognitive trajectories, with and without covarying for all neuropathologies. Classes were also compared on rates of incident MCI/dementia. RESULTS: Five classes were identified: Class 1Low Life Space (lowest lifestyle engagement), Class 2PA (high physical activity), Class 3Low Avg (low to average lifestyle engagement), Class 4Balanced (high average lifestyle engagement), and Class 5Social (large social network). Classes 4Balanced and 5Social had the lowest AD burden, and Class 2PA had the lowest CVD burden. Classes 2-5 had significantly less steep global cognitive decline compared to Class 1Low Life Space, with comparable effect sizes before and after covarying for neuropathological burden. Classes 4Balanced and 5Social exhibited the lowest rates of incident MCI/dementia. CONCLUSIONS: Lifestyle behavior patterns among older adults account for differential rates of cognitive decline and clinical progression. Those with at least average engagement across all lifestyle domains exhibit greater cognitive stability after adjustment for neuropathology, highlighting the importance of engagement in multiple healthy lifestyle behaviors for later life cognitive health.

Family Ties and Older Adult Well-Being: Incorporating Social Networks and Proximity.

OBJECTIVES: This paper examines the family ties of older adults in the United States and how they are associated with mental health and social activity. We compare older adults with 4 types of family ties: adults "close" to family in proximity and social network, "kinless" older adults without a partner or children, "distanced" adults who live far from close kin, and "disconnected" older adults who do not report kin in their social network or do not report a location for some kin. METHODS: Using pooled data from the National Health and Aging Trends Study 2015-2019 for older adults aged 70 and older (N = 24,818 person-waves), we examine how family ties are associated with mental health and social activity, and whether lacking family is tied to poor well-being because older adults' needs are not being met. RESULTS: Kinless older adults and disconnected older adults have poorer outcomes (lower mental health scores and less social activity), compared to those close to their family. These findings suggest that both the presence and quality of the connection, as measured here via both location and social network, are critical for understanding which older adults are "at risk." Older adults who were not geographically proximate to their close kin (i.e., distanced) were not disadvantaged relative to those close to their families. Unmet needs do not help explain these patterns. DISCUSSION: Our results highlight that family ties are important for older adults well-being, not just through their existence but also their quality and strength.

Association between oral hypofunction and general health: a systematic review.

BACKGROUND: Oral hypofunction comprises 7 oral function conditions, including mastication, swallowing, pronouncing, oral hygiene, and oral dryness. However, it remains unresolved whether having oral hypofunction and each individual condition adversely affect general health. This study aimed to investigate the association between oral hypofunction and general health, encompassing physical, psychological, and social dimensions. METHODS: Oral hypofunction was diagnosed following the criteria proposed by the 2016 Japan Society of Gerodontology, comprising 7 oral function conditions. Oral hypofunction was diagnosed when at least 3 conditions presented. The selected studies eligible for reviewing were based on the PI(E)CO criteria: P (population), adult and older adults; I/E (intervention/exposure), having oral hypofunction by considering overall and individual 7 oral function conditions; C (comparator), not having oral hypofunction; O (outcome), the general health status, encompassing physical, psychological, and social dimensions. Electronic search limited to English articles was performed through PubMed, Scopus, and Cochrane Database of Systematic Reviews databases from January 2016 to June 2023. The included studies were assessed for quaility and risk of bias using the modified Newcastle-Ottawa scale. Qualitative analyses were performed on the general outcome, and having oral hypofunction considering overall and individual oral function conditions. RESULTS: Ten studies were included in the final syntheses. One was a prospective cohort, one was a case-control, and the others were cross-sectional studies. All included studies were high quality. General health outcomes were mostly frailty, sarcopenia, and malnutrition, whereas mild cognitive impairment,social withdrawal, and gastric cancer prognosis were identified in one of the included studies. The association between general health and having oral hypofunction was stronger than when considering an individual condition. The health outcomes were predominantly associated with mastication and swallowing, whereas their relationships with oral hygiene and dryness were less likely to be reported. CONCLUSIONS: The present review found an association between the presence of oral hypofunction and impaired general health. However, the specific impact on individual physical, psychological, and social dimensions cannot be distinctly delineated. Further prospective studies are required to clarify the causal-effect relationship between oral and general health.

Hearing Loss and Subjective Well-Being Among Older Adults: Mediating Effect of Social Activity and Cognitive Function.

OBJECTIVES: To examine the relationship between hearing loss and subjective well-being (SWB) and to investigate the mediating roles of social activity and cognitive function in the link between hearing loss and SWB. METHODS: An analysis of 11,949 older Chinese adults was conducted from the 2018 wave of the Chinese Longitudinal Health Longevity Survey. Multiple linear regression and mediation analysis were conducted. RESULTS: Hearing loss had a significant negative association with SWB (B = -0.787; 95% CI: -0.961, -0.613). Hearing loss influenced older adults' SWB in the following three ways: first, via the partial mediating effect of social activity (B = -0.021, 95% CI: -0.036, -0.009); second, via the partial mediating effect of cognitive function (B = -0.275, 95% CI: -0.347, -0.252); and third, via the serial mediating effects of social activity and cognitive function (-0.016, 95% CI: -0.021, -0.011). CONCLUSIONS: Social activity and cognitive function play a serial intermediary role in the relationship between hearing loss and SWB among older Chinese adults. CLINICAL IMPLICATIONS: Multidimensional health and social interventions aimed at improving mental health and social inclusion among adults with hearing loss should be recommended.

Association between hearing status and social participation in Japanese older adults: A cross-sectional study from the Japan gerontological evaluation study.

PURPOSE: Hearing is known to decline with age. As sensitivity to speech declines, conversation becomes more difficult and social interactions are affected, resulting in increased risk of cognitive decline. This study aimed to examine the relationship between hearing status and social participation. MATERIALS AND METHODS: The study included 21,117 adults aged 65 years or older who responded to a survey in 2019. The survey asked participants about their hearing status and how frequently they participated in certain social activities. RESULTS: The analysis of the relationship between degree of hearing and social activity showed lower hearing status odds ratios for those who participated more frequently in social activities compared to those who participated less frequently. The odds ratios were as follows, hobby clubs (OR 0.81, 95%CI 0.78-0.84), activities such as teaching skills or passing on experiences to others (OR 0.69, 95%CI 0.65-0.75), and meeting with friends (OR 0.77, 95%CI 0.74-0.79). Compared to those who did not participate in social activities, those who participated in three or more types of groups had significantly lower hearing impairment (OR 0.75, 95% CI 0.72-0.79). CONCLUSION: Hearing impairment was shown to inhibit participation in activities, including those that require communication with multiple people or smooth communication, those that involve a wide range of ages, and those that involve work and movement. Hearing impairment should be identified and addressed in its early stages to prevent its negative impact on social participation.

The complex interplay between weather, social activity, and COVID-19 in the US.

Empirical studies on the impact of weather and policy interventions on Covid-19 infections have dedicated little attention to the mediation role of social activity. In this study, we combine mobile locations, weather, and COVID-19 data in a two-way fixed effects mediation model to estimate the impact of weather and policy interventions on the COVID-19 infection rate in the US before the availability of vaccines, disentangling their direct impact from the part of the effect that is mediated by the endogenous response of social activity. We show that, while temperature reduces viral infectiousness, it also increases the amount of time individuals spend out of home, which instead favours the spread of the virus. This second channel substantially attenuates the beneficial effect of temperature in curbing the spread of the virus, offsetting one-third of the potential seasonal fluctuations in the reproduction rate. The mediation role of social activity is particularly pronounced when viral incidence is low, and completely offsets the beneficial effect of temperature. Despite being significant predictors of social activity, wind speed and precipitation do not induce sufficient variation to affect infections. Our estimates also suggest that school closures and lockdowns are effective in reducing infections. We employ our estimates to quantify the seasonal variation in the reproduction rate stemming from weather seasonality in the US.

The effects of COVID-19-era unemployment and business closures upon the physical and mental health of older Europeans: Mediation through financial circumstances and social activity.

COVID-19-era lockdown policies resulted in many older persons entering unemployment, facing financial difficulties and social restrictions, and experiencing declining health. Employing the Survey of Health, Ageing and Retirement in Europe's first COVID-19 module (summer 2020) (N = 11,231) and the Karlson-Holm-Breen method for decomposition of effects within non-linear probability models (logistic regression modelling), we examined associations of pandemic-era lost work with older Europeans' (50-80 years of age) self-assessed health, depressive symptoms, and anxiety symptoms, and mediation through households' difficulties making ends meet, loneliness, and curtailed face-to-face contact with non-relatives. We find that lost work was associated with detriments in all three health outcomes. Total mediation was 23% for worsened self-assessed health, 42% for depressive symptoms, and 23% for anxiety symptoms. In all cases, combined mediation through the two social activity variables was approximately twice the magnitude of mediation through household financial difficulties. This evidence highlights the extent of employment's value for friendship formation and sustenance, and social activity, during the pandemic-era social restrictions. This might be accentuated among older persons because of the social constrictions often concomitant to advancing age. These results emphasize that the social correlates of lost employment, beyond the financial concomitants, should receive thorough research and policy attention, perhaps especially for older adults during public health crises.

Factors to Consider when Introducing Digital Social Activities to Older Persons with Home Care.

Social isolation and loneliness have become everyday concerns for populations all over the world as these factors are affecting both physical and mental health in a negative way. Feelings of isolation and loneliness are increasingly acknowledged as a health risk among older persons. ICTs have been recognized as effective tools to combat social isolation among older people. The aim of this study was to explore factors of significance when introducing a tablet-based system providing digital social activities for older persons with home care. Participants were 17 persons, age 70 and older, who lived alone and had assistance from home care. This exploratory study used cross-sectional qualitative data analyzed through thematic analysis. Three themes were generated: 1) lacking vocabulary related to the context, 2) intuitive user interface may replace extensive instructions and 3) unwillingness to commit to a pre-defined measure of performance.

Equal Opportunities in Aging: Income Level Moderates the Relationship Between Infrequent Participation in Formal Social Activities and Loneliness Among Older Adults.

Infrequent participation in formal social activities among older adults increases the risk of loneliness. We examined whether a higher income level moderates the relationship between infrequent participation and loneliness. Utilizing data from wave #6 of the European Health, Aging, and Retirement Survey, we included participants aged 65+ (i.e., older adults), non-participants in the labor force (N = 24 819). Loneliness was measured by the R-UCLA loneliness questionnaire, formal social activity by participation frequency in volunteer/charity activities, educational course/training, sports/social/other clubs, and political/community organizations. Hierarchical multiple regression models examined relationships between variables, controlled by country. Infrequent participation in formal social activity associated with higher risk of loneliness. However, income moderated the association between participation and loneliness; infrequently participating older adults with low-to-moderate income were more vulnerable to loneliness than higher income older adults, for whom infrequent participation did not increase loneliness. This reinforces the need to encourage formal social activity with subsidy for low-to-moderate income older adults.
