Social capital, deprivation and self-rated health: Does reporting heterogeneity play a role? Results from the English Longitudinal Study of Ageing

Mental health around retirement: evidence of Ashenfelter's dip

BACKGROUND

Mental health issues among retirees have become increasingly concerning because the aging population presents a significant challenge globally, particularly in Western countries. Previous studies on this issue are plagued with bias owing to lacking panel data and estimation strategies. This study investigated the depression levels of European adults around the time of retirement.

METHODS

We used data obtained from Waves 1-7 of the Survey of Health, Ageing, and Retirement in Europe (SHARE) to create panel data covering the 2004-2017 period. Wave 3 (SHARELIFE) was excluded from the sample because it provided mismatched information. Fixed-effects (FE) and fixed-effects instrumental variables (FE-IV) models with multiple imputations were employed to examine the impacts of retirement on mental health before and after retirement, where being over pension age (normal and early) was used as the instrument variable.

RESULTS

Our results indicated that retirement based on aspirational motivations (β =  - 0.115, p < 0.001) and positive circumstances (β =  - 0.038, p < 0.001) significantly reduced depression, whereas retiring under negative circumstances could deteriorate one's mental health (β = 0.087, p < 0.001). FE and FE-IV models indicated that overall, retiring reduced retirees' depression (β =  - 0.096, p < 0.001 and β =  - 0.261, p < 0.001, respectively). The results of FE-IV models showed that adults planning to retire in the next two years experienced less depression compared with others in the workforce (λ =  - 0.313, p < 0.01). These adults must have adjusted their lifestyles in response to their impending retirement, thereby evincing Ashenfelter's dip. Two years after retirement, when the "honeymoon" phase was over, retirees may have completely adapted to their new lives and the effect of retirement was no longer important.

CONCLUSIONS

Retirement improves mental health before it happens, but not after. Increasing the pension eligibility age may postpone the beneficial effects of retirement on health. However, policy implications should be tailored according to the unique situations of each country, job sector, and population. Providing flexible schemes regarding retirement timing decisions would be better than a generalized retirement policy.

Association between social capital and self-rated health among community-dwelling older adults

Background

It is less known about whether the association of social capital with self-rated health (SRH) varies by the presence of health conditions and how social capital, together with other variables, is linked to self-rated health in later life.

Objectives

This article aimed to explore the association of social capital with self-rated health and to examine whether the association varies among older people with and without health conditions, with a special focus on how social capital and relevant factors have an effect on self-rated health among community-dwelling older adults.

Methods

Cross-sectional data were obtained from a survey that commenced from July to September 2017 in Anhui Province. Data on socio-demographic information, social capital (six dimensions), and self-rated health were analyzed. Binary logistic regression and classification and regression tree (CART) models were used to estimate the association.

Results

Based on the findings, we found that social capital regarding less social support (adjusted odds ratio (AOR) = 1.57, 95% CI: 1.21-2.04), and less reciprocity (AOR = 1.73, 95% CI: 1.29-2.31) were associated with self-rated health among general older adults. Social capital as measured by less social participation (AOR = 1.55, 95% CI: 1.06-2.27), less cohesion (AOR = 0.63, 95% CI: 0.42-0.94), and less reciprocity (AOR =1.77, 95% CI: 1.17-2.68) were linked to self-rated health among older people with health conditions. While social capital regarding less social support (AOR = 2.15, 95% CI: 1.39-3.33) was related to self-rated health among older people without health conditions. We observed the interacting effect of social capital in the CART model, an implication that much focus should be geared toward vulnerable subgroups, especially depressed and lonely older people, as they have low reciprocity and little cohesion.

Conclusion

This work demonstrates that social capital may be relevant in devising programs and measures to improve self-rated health among community-dwelling older adults with comorbidity.

Translating Planetary Health Principles Into Sustainable Primary Care Services

Global anthropogenic environmental degradations such as climate change are increasingly recognized as critical public health issues, on which human beings should urgently act in order to preserve sustainable conditions of living on Earth. "Planetary Health" is a breakthrough concept and emerging research field based on the recognition of the interdependent relationships between living organisms-both human and non-human-and their ecosystems. In that regards, there have been numerous calls by healthcare professionals for a greater recognition and adoption of Planetary Health perspective. At the same time, current Western healthcare systems are facing their limits when it comes to providing affordable, equitable and sustainable healthcare services. Furthermore, while hospital-centrism remains the dominant model of Western health systems, primary care and public health continue to be largely undervalued by policy makers. While healthcare services will have to adapt to the sanitary impacts of environmental degradations, they should also ambition to accompany and accelerate the societal transformations required to re-inscribe the functioning of human societies within planetary boundaries. The entire health system requires profound transformations to achieve this, with obviously a key role for public health. But we argue that the first line of care represented by primary care might also have an important role to play, with its holistic, interdisciplinary, and longitudinal approach to patients, strongly grounded in their living environments and communities. This will require however to redefine the roles, activities and organization of primary care actors to better integrate socio-environmental determinants of health, strengthen interprofessional collaborations, including non-medical collaborations and more generally develop new, environmentally-centered models of care. Furthermore, a planetary health perspective translated in primary care will require the strengthening of synergies between institutions and actors in the field of health and sustainability.

Income, Relative Deprivation and the Self-Rated Health of Older People in Urban and Rural China

Background: Substantial evidence indicated that absolute income is directly associated with health. Few studies have, however, examined if relative income may be equally associated with health. This study aimed to investigate the association between absolute income/relative deprivation (RD) and self-rated health (SRH). We also investigated whether the urban-rural difference was existing in these associations.

Methods: Using cross-sectional data of 7,070 participants in the Shandong Family Health Service Survey of older people, this study applied binary logistic model and semi-parametric model to estimate the effect of absolute income and relative deprivation on SRH of older people. The Kakwani Index was used as a measure of relative deprivation at the individual level.

Results: Absolute income has a significant positive effect on the SRH among both urban and rural older people. When considered RD as a variable, both absolute income and RD have negative significant effects on SRH among all older people. In addition, the negative effect of RD on rural elderly is more pronounced than that of urban older populations. Semi-parametric regression results show that there was a complex non-linear relationship between income and SRH. Psychological distress substantially attenuated the association between relative deprivation and SRH.

Conclusions: Relative deprivation is negatively associated with self-rated health in both urban and rural older people after controlling the absolute income. RD may partly explain the association between income inequality and worse health status. Compared with the urban elderly, the effect of income-based relative deprivation on SRH was more pronounced among the rural elderly, and more care should be given to the lower income and rural older populations.

Social capital and self-rated health of residents of Gauteng province: Does area-level deprivation influence the relationship?

Although social capital has been linked to population health, there is a dearth of studies on the phenomenon especially in sub-Saharan Africa. We investigated the individual and contextual effects of social capital indicators (group membership, registered to vote, perception towards safety in community and generalised trust) on the self-rated health (SRH) of the residents of Gauteng province. We used data from the 2015 Quality of Life (QoL) survey, which included a random representative sample of 27476 residents (level 1) in 508 administrative wards (level 2). We employed a multilevel logistic regression to examine the association of social capital and SRH (good vs poor). After adjusting for individual and area-level factors, no main effect of group membership (Adjusted OR: 0.93: 95% CI: 0.85-1.02), generalised trust (Adjusted OR: 1.01: 95% CI: 0.89-1.49) and registered to vote (Adjusted OR: 0.95; 95% CI: 0.82-1.10) was observed. However, if respondents were positive in their perception towards safety in community, there was a positive association with good SRH (Adjusted OR: 1.15; 95% CI: 1.01-1.31); while if residents reported a negative perception towards safety in community, a strong negative association with good SRH (Adjusted OR: 0.70; 95% CI: 0.62-0.79) was observed. Both ward variance and median odds ratio (MOR) indicate significant differences in good SRH by wards. A strong positive joint effect on the multiplicative scale was observed between satisfied with safety and the ward-level South African Multiple Deprivation Poverty Index (SAMPI), while a strong negative joint effect was also observed on a multiplicative scale between dissatisfied with safety and the SAMPI. Perception of safety in community is the core domain of social capital that significantly impacts the SRH of residents of Gauteng. Although the effect of perception towards safety in community on good SRH is influenced by ward deprivation,the effect is not dependent on the level of deprivation. Contextual factors as evidenced by the persistent MOR, in addition to individual factors, explain variation in reporting good SRH in the study area.

Educational Inequalities in Self-Rated Health in Europe and South Korea

While numerous comparative works on the magnitude of health inequalities in Europe have been conducted, there is a paucity of research that encompasses non-European nations such as Asian countries. This study was conducted to compare Europe and Korea in terms of educational health inequalities, with poor self-rated health (SRH) as the outcome variable. The European Union Statistics on Income and Living Conditions and the Korea National Health and Nutrition Examination Survey in 2017 were used (31 countries). Adult men and women aged 20+ years were included (207,245 men and 238,007 women). The age-standardized, sex-specific prevalence of poor SRH by educational level was computed. The slope index of inequality (SII) and relative index of inequality (RII) were calculated. The prevalence of poor SRH was higher in Korea than in other countries for both low/middle- and highly educated individuals. Among highly educated Koreans, the proportion of less healthy women was higher than that of less healthy men. Korea’s SII was the highest for men (15.7%) and the ninth-highest for women (10.4%). In contrast, Korea’s RII was the third-lowest for men (3.27), and the lowest among women (1.98). This high-SII–low-RII mix seems to have been generated by the high level of baseline poor SRH.

Factors related to preference for participation and degree of commitment in community activities among older adults in Japanese depopulated areas

To address the rapid increase in the ageing population, Japan implemented the Long-Term Care Insurance System (LTCS) in 2000. Additionally, a community-based integrated community care system was released in 2012. The purpose of these policies was to help older people who need care or support to continue to live their preferred lifestyles in their own communities. According to this paradigm, older residents are themselves considered members of the community caregiving team and expected to participate in volunteer activities to help the neighbourhood. One such activity is social participation including community activities. Many factors influencing social participation have been found in previous literature. However, knowledge of specific factors about community activities is limited, even though these kinds of activities have attracted policy attention. Our study examined factors related to thoughts about community activities among people aged >40 years. We conducted random sampling in two depopulated areas in Japan and used an anonymous mail survey method. Our survey consisted of three parts: social demographics, health and life, and medical/long-term care. A total of 2,466 individuals participated in the study (response rate 52.2%), whose average age was 64.2 (SD = 10.3) and 46.5% (n = 1,146) were female. Items including talking with neighbours frequently (social demographics), higher self-rated health (health and life), the need for health consultations and the desire to take care of family members when they need help (medical/long-term care) were significantly related to both preference for participation and degree of commitment in community activities. To encourage participation in community activities among older citizens, we recommend interventions related to health literacy and family ties.

Social capital and physical health: An updated review of the literature for 2007-2018

PURPOSE

Social capital is frequently indicated as a determinant of population health. Despite an increase in the frequency of public health studies including such measures, our understanding of social capital's effects on health remains unclear. In 2008, a systematic review of the "first decade" of research on social capital and health was published in the textbook Social Capital and Health. Our study intends to update and expand upon this original review to account for developments in the literature over the second decade of research on social capital and health.

METHODS

We employed a systematic review of empirical studies investigating the relationship between measures of social capital and physical health outcomes published between January 1, 2007 and December 31, 2018. To identify potential studies, we conducted searches of PubMed, Embase, and PsychINFO databases in January 2019 using combinations of "social capital" and "physical health" search terms.

RESULTS

We identified 1,608 unique articles and reviewed 145 studies meeting our inclusion criteria. The most frequently examined health condition was self-reported health (57%), followed by mortality (12%), cardiovascular diseases (10%), obesity (7%), diabetes (6%), infectious diseases (5%), and cancers (3%). Of these studies, 127 (88%) reported at least partial support for a protective association between social capital and health. However, only 41 (28%) reported exclusively positive findings. The majority (59%) of results were mixed, suggesting a nuanced relationship between social capital and health. This finding could also be indicative of differences in study design, which showed substantial variation.

CONCLUSIONS

Despite limitations in the literature, our review chronicles an evolution in the field of social capital and health in terms of size and sophistication. Overall, these studies suggest that social capital may be an important protective factor for some physical health outcomes, but further research is needed to confirm and clarify these findings.

Towards patients' understanding of health-related quality of life-a mixed-method study in psoriasis and multiple sclerosis

PURPOSE

Patients' individual understanding of health-related quality of life (HRQoL) varies widely, making the measurement of this complex and subjective construct challenging. Anchoring vignettes, i.e., descriptions of fictive patients may provide insights into patients' individual questionnaire reference frames, assessment processes, and understanding of HRQoL. This study analyzes how patients assess HRQoL of vignettes.

METHODS

This exploratory mixed-method study included 100 patients with a chronic disease (50 multiple sclerosis (MS); 50 psoriasis). Sixteen vignettes, two for each domain of the SF-12v2, were developed based on literature recommendations and pretested in a convenience sample of seven healthy individuals. Patients assessed their own HRQoL and HRQoL of the vignettes on the SF-12v2. In semi-structured interviews, they justified their assessments. We quantitatively analyzed associations of vignette assessments with individual characteristics using linear regression models and qualitatively analyzed assessment justifications.

RESULTS

Patients' age and disease were significant (p < 0.05) predictors for ten and seven vignette assessments, respectively. Older patients assessed vignettes being less extreme; patients diagnosed with MS rated them more positively. Overall, adjusted R² values ranged from 0.033 to 0.172. Qualitatively, most of the ratings were based on the evaluation of symptoms or impairments in daily life. Fewer participants ranked different dimensions of HRQoL in a personal hierarchy or assumed impairments beyond the vignette description.

CONCLUSIONS

The understanding of HRQoL may vary substantially and is associated with individual characteristics, individual assessment strategies, and probably other intrinsic factors as explained variance was quite low. Therefore, usage of generic instruments only allows for limited comparison across groups.

The Relationship between Social Cohesion and Urban Green Space: An Avenue for Health Promotion

Social cohesion involves the interpersonal dynamics and sense of connection among people. Increased social cohesion can be associated with various physical and psychological health benefits. The presence of urban green spaces can encourage positive social interactions that cultivate social cohesion in ways that enhance health and well-being. Urban green spaces have also been linked to positive health behaviors and outcomes including increased physical activity and social engagement. Understanding the relationship between social cohesion and urban green space is important for informing holistic approaches to health. In this article, we discuss how positive interactions in urban green space can catalyze social cohesion, social capital and critical health-promoting behaviors that may enhance psychological health and well-being. We also summarize the strengths and limitations of previous studies and suggest directions for future research.
