Polypharmacy prevalence among older adults based on the survey of health, ageing and retirement in Europe

Polypharmacy, a common condition among the elderly, is associated with adverse outcomes, including increased healthcare costs, due to higher mortality, falls and hospitalizations rates, adverse drug reactions, drug-drug reactions and medication nonadherence. This study aims to evaluate the prevalence and factors related to polypharmacy in older adults across 17 European countries, plus Israel. In this cross-sectional analysis, we used data from participants aged 65 or more years from Wave 6 of the Survey of Health, Ageing, and Retirement in Europe (SHARE) database. Polypharmacy was defined as the concurrent use of five or more medications. Age, gender, education, physical inactivity, number of limitations with activities of daily living, network satisfaction, quality of life, depression, number of chronic diseases and difficulty taking medication variables were found to be associated with polypharmacy. Our results showed a prevalence of polypharmacy ranging from 26.3 to 39.9%. Switzerland, Croatia and Slovenia were the countries with the lowest prevalence, whereas Portugal, Israel and the Czech Republic were the countries where the prevalence of polypharmacy was the highest. Age, gender, number of limitations with activities of daily living, number of chronic diseases, quality of life, depression, physical inactivity, network satisfaction, difficulty in taking medications, years of education and shortage of money were significant variables associated with polypharmacy. Polypharmacy is a highly prevalent condition in the elderly population. Identification of variables associated with polypharmacy, such as those identified in this study, is important to identify and monitor elderly groups, which are most vulnerable to polypharmacy.

The Causal Effect of Education on Health: What is the Role of Health Behaviors?

We investigate the causal effect of education on health and the part of it that is attributable to health behaviors by distinguishing between short-run and long-run mediating effects: whereas, in the former, only behaviors in the immediate past are taken into account, in the latter, we consider the entire history of behaviors. We use two identification strategies: instrumental variables based on compulsory schooling reforms and a combined aggregation, differencing, and selection on an observables technique to address the endogeneity of both education and behaviors in the health production function. Using panel data for European countries, we find that education has a protective effect for European men and women aged 50+. We find that the mediating effects of health behaviors-measured by smoking, drinking, exercising, and the body mass index-account in the short run for around a quarter and in the long run for around a third of the entire effect of education on health.

A new comprehensive and international view on ageing: introducing the 'Survey of Health, Ageing and Retirement in Europe'

This paper introduces the 'Survey of Health, Ageing and Retirement in Europe' (SHARE) to researchers on ageing. SHARE provides an infrastructure to help researchers better understand the individual and population ageing process: where we are, where we are heading to, and how we can influence the quality of life as we age, both as individuals and as societies. The baseline wave in 2004 provides data on the life circumstances of some 27,000 persons aged 50 and over in 11 European countries, ranging from Scandinavia across Western and Central Europe to the Mediterranean. SHARE has made great efforts to deliver truly comparable data, so we can reliably study how differences in cultures, living conditions and policy approaches shape the life of Europeans just before and after retirement. The paper first describes the SHARE data. In order to demonstrate its value, it then presents highlights from the three main research areas covered by SHARE, namely economics, sociology, and health.

Exploring the relationship between national economic indicators and relative fitness and frailty in middle-aged and older Europeans

BACKGROUND

on an individual level, lower-income has been associated with disability, morbidity and death. On a population level, the relationship of economic indicators with health is unclear.

OBJECTIVE

the purpose of this study was to evaluate relative fitness and frailty in relation to national income and healthcare spending, and their relationship with mortality.

DESIGN AND SETTING

secondary analysis of data from the Survey of Health, Ageing and Retirement in Europe (SHARE); a longitudinal population-based survey which began in 2004.

SUBJECTS

a total of 36,306 community-dwelling people aged 50 and older (16,467 men; 19,839 women) from the 15 countries which participated in the SHARE comprised the study sample. A frailty index was constructed as the proportion of deficits present in relation to the 70 deficits available in SHARE. The characteristics of the frailty index examined were mean, prevalence of frailty and proportion of the fittest group.

RESULTS

the mean value of the frailty index was lower in higher-income countries (0.16 ± 0.12) than in lower-income countries (0.20 ± 0.14); the overall mean frailty index was negatively correlated with both gross domestic product (r = -0.79; P < 0.01) and health expenditure (r = -0.63; P < 0.05). Survival in non-frail participants at 24 months was not associated with national income (P = 0.19), whereas survival in frail people was greater in higher-income countries (P < 0.05).

CONCLUSIONS

a country's level of frailty and fitness in adults aged 50+ years is strongly correlated with national economic indicators. In higher-income countries, not only is the prevalence of frailty lower, but frail people also live longer.

The impact of caring for grandchildren on the health of grandparents in Europe: A lifecourse approach

Grandparents are becoming an increasingly important source of childcare. However, caring for grandchildren may have negative health consequences particularly for grandparents with intensive commitments such as those with primary care responsibilities. To date most studies on this issue are based on cross-sectional data and do not take earlier life circumstances into account. Thus, it is not known whether (or to what extent) the relationship between grandparental childcare and health is due to cumulative advantage or disadvantage throughout the lifecourse or to the impact of grandchild care per se. Employing data from waves 1-3 of the Survey of Health, Ageing and Retirement in Europe we investigated the longitudinal relationship between grandparental childcare (i.e. intensive and non-intensive) and health once cumulative histories of advantage or disadvantage are taken into account. We used latent class analysis to categorise respondents according to childhood socio-economic and health conditions drawing on life history information. Experiences in adulthood (e.g. periods of ill health) were also captured. We created a latent continuous physical health variable based on self- and observer-measured indicators. OLS regression was used to explore the association between physical health at wave 2 and grandparental childcare at baseline, controlling for conditions in childhood and adulthood, and for health and socio-economic characteristics. We found a positive longitudinal association between grandchild care and health even after earlier life health and socio-economic conditions were taken into account. However, this significant association was found only for grandmothers, and not grandfathers. Our results suggesting the health benefits of grandchild care are important given the widespread provision of grandparental childcare in Europe. However, further research on underlying mechanisms and causal pathways between grandchild care and grandparent health, as well as on gender differences in the pattern of association, is needed.

Children's impact on the mental health of their older mothers and fathers: findings from the Survey of Health, Ageing and Retirement in Europe

The relation between social support and mental health has been thoroughly researched and structural characteristics of the social network have been widely recognised as being an important component of social support. The aim of this paper is to clarify the association between children and depressive mood states of their older parents. Based on international comparative data from the Survey of Health, Ageing and Retirement in Europe we analysed how the number of children, their proximity and the frequency of contact between older parents and their children are associated with the mental health of older people, using the EURO-D index. Our results indicate a positive association of children and depressive mood since childless men and women report more depressive symptoms. Moreover, few contacts with children were associated with an increased number of depressive symptoms. The family status was related to mental health as well: older men and women living with a spouse or partner had the lowest levels of depression. Interestingly, the presence of a spouse or partner was more relevant for the mental health of older people than the presence of, or contact with, their children.

Confidant network types and well-being among older europeans

PURPOSE OF THE STUDY

To derive a typology of confidant networks among older adults in Europe and to examine them in relation to country differences and well-being (CASP-12).

DESIGN AND METHODS

The study population was composed of persons aged 65 and older in 16 countries from the 4th wave of the Survey of Health, Ageing and Retirement in Europe (N = 28,697). K-means cluster analysis was applied to data from a newly implemented name-generating network inventory. CASP-12 scores were regressed on network type controlling for country and potential sociodemographic and health confounders.

RESULTS

Six prototypical confidant network types were discerned, including proximal and distal family-based networks of varying configurations, as well as friend-based and other-based network types. Regional country differences in network type constellations were observed. Better well-being was found to be associated with network types with greater social capital. Respondents with no named confidants had the lowest CASP-12 scores, and those embedded in "other" network types also exhibited a negative association with well-being.

IMPLICATIONS

The study demonstrates the utility of name-generating network inventories in understanding the social capital of older persons. It also shows that accessible family ties are strong correlates of well-being in this population. Finally, it documents the importance of improving the means to detect the small but significant subgroup of isolated older people-those who have no confidants on whom they may rely.

The Health Impact of Intensive and Nonintensive Grandchild Care in Europe: New Evidence From SHARE

OBJECTIVES

Grandparents are an important source of childcare. However, caring for grandchildren may affect grandparents' health in both positive and negative ways. Our study examines the association between grandparental childcare and grandparents' health at 2- and 4-year follow-up.

METHOD

Our study is based on grandparents aged 50 and older from Waves 1-4 of the Survey of Health, Ageing and Retirement in Europe (SHARE). Using multivariate analyses, we investigated associations between intensive and nonintensive grandparental childcare at Wave 2 and subsequent health (self-rated health, depressive symptoms, and disability) controlling for covariates and health at baseline. Associations between changes over time in grandparental childcare and health at follow-up were also explored. Multiple imputation techniques and sensitivity analyses were undertaken to investigate possible biases arising from sample attrition.

RESULTS

Grandparents looking after grandchildren, whether intensively or nonintensively, experienced some health benefits. Associations strengthened when attrition was accounted for, particularly if it is assumed that those who dropped out of the study were in poor health.

DISCUSSION

Our results show better health among grandparents who provided grandchild care in the European countries studied. These results are important given the widespread provision of grandchild care in Europe.

Anxiety, Depression and Quality of Life in Older Adults: Trajectories of Influence across Age

This study focuses on the influence of anxiety and depression on individual trajectories of quality of life in old age through a longitudinal approach. A representative sample of adults aged 50+ living in Portugal and participating in wave 4 (W4) and wave 6 (W6) of the Survey of Health, Ageing and Retirement in Europe (SHARE) project was considered. Participants, 1765 at baseline (W4) and 1201 at follow up (W6), were asked about their quality of life (CASP-12) and emotional status (Euro-D scale; five items from the Beck Anxiety Inventory). Linear Mixed Effects models were performed to identify factors associated with changes in quality of life across age. Increasing age was found to have a significant negative effect on quality of life. Lower education and higher levels of depression and anxiety at baseline were also associated with worse quality of life; 42.1% of the variation of CASP-12 across age was explained by fixed and random effects, being depression followed by anxiety as the factors that presented with the highest relative importance. Both depression and anxiety play an important role in quality of life in older adults and must be acknowledged as important intervention domains to foster healthy and active aging.

A "healthy immigrant effect" or a "sick immigrant effect"? Selection and policies matter

Previous literature on a variety of countries has documented a "healthy immigrant effect" (HIE). Accordingly, immigrants arriving in the host country are, on average, healthier than comparable natives. However, their health status dissipates with additional years in the country. HIE is explained through the positive self-selection of healthy immigrants as well as the positive selection, screening and discrimination applied by host countries. In this article we study the health trajectories of immigrants within the context of selection and migration policies. Using SHARE data we examine the HIE, comparing Israel and 16 European countries that have fundamentally different migration policies. Israel has virtually unrestricted open gates for Jewish people around the world, who in turn have ideological rather than economic considerations to move. European countries have selective policies with regards to the health, education and wealth of migrants, who also self-select themselves. Our results provide evidence that (1) immigrants who move to Israel have compromised health and are significantly less healthy than comparable natives. Their health disadvantage persists for up to 20 years of living in Israel, after which they become similar to natives; (2) immigrants who move to Europe have significantly better health than comparable natives. Their health advantage remains positive for many years. Even though during some time lapses they are not significantly different from natives, their health status never becomes worse than that of natives. Our results are important for migration policy and relevant for domestic health policy.

Social networks and mental health change in older adults after the Covid-19 outbreak

OBJECTIVES

This article examines the influence of social networks on selected aspects of mental health following the outbreak of the coronavirus.

METHOD

We linked data from a post outbreak telephone survey in 2020 by the Survey of Health, Ageing and Retirement in Europe, with baseline data from SHARE Wave 6 (2016) (n = 33,485). Two mental health measures (depression and anxiety) were regressed on social network variables relevant to the Covid-19 crisis (frequency of face-to-face contact and frequency of contact through electronic means), controlling for confounders. Interactions of age group and social networks were considered. Baseline mental health was controlled, focusing the analysis on post-outbreak mental health change.

RESULTS

Face-to-face network contact significantly reduced negative mental health changes while electronic contact significantly increased them. The age interactions were insignificant. Country differences were observed.

CONCLUSION

The findings suggest that face-to-face social networks can moderate the negative impact of the COVID-19 pandemic on important aspects of mental health.

Cross-national comparison of sex differences in ADL and IADL in Europe: findings from SHARE

Women experience greater longevity than men, but have poorer health, although sex differences vary across health measures and geographical regions. We aim to examine sex differences in Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) over age across European regions in a cross-sectional setting including 51,292 men and 62,007 women aged 50+ from a pooled sample of waves 1 (2004-2005) to 6 (2015) in the Survey of Health, Ageing and Retirement in Europe. ADL and IADL were dichotomised into no limitations and at least one limitation. Binomial regression models were used to estimate absolute and relative sex differences. Women had higher risk than men of ADL limitations (RR = 1.21, 95% CI 1.16; 1.27) and IADL limitations (RR = 1.54, 95% CI 1.48; 1.60), corresponding to risk differences of 1.3% and 5.7%, respectively. When we stratified by age groups and regions, sex differences in ADL were found in all age groups in Southern Europe, in the age groups 65-79 years and 80+ years in Western and Eastern Europe, and from the age of 80 in Northern Europe. For IADL, sex differences were found in all age groups in the four European regions, except from ages 50-64 in Eastern Europe. The absolute sex differences increased with age in all European regions. In conclusion, our results lend support for the male-female health survival paradox by showing that European women have higher risk of ADL and IADL limitations than European men and that sex differences increase with advancing age.

Sex Differences in Comorbidity and Frailty in Europe

OBJECTIVES

To examine sex differences in prevalent comorbidity and frailty across age and European regions.

METHODS

This is a cross-sectional study based on 113,299 Europeans aged 50+ participating in the Survey of Health, Ageing and Retirement in Europe from 2004-2005 to 2015. Sex differences in the Comorbidity Index and the Frailty Phenotype were investigated using ordinal logistic regressions.

RESULTS

European women had generally higher odds of prevalent comorbidity (OR 1.11, 95% CI 1.07-1.15) and frailty (OR 1.56, 95% CI 1.51-1.62). Sex differences increased with advancing age. No overall sex difference in comorbidity was found in Western Europe, but women had more comorbidity than men in Eastern (OR 1.30, 95% CI 1.18-1.44), Southern (OR 1.23, 95% CI 1.15-1.30), and Northern (OR 1.08, 95% CI 1.01-1.16) Europe. Women were frailer than men in all regions, with the largest sex difference in Southern Europe (OR 1.84, 95% CI 1.72-1.96).

CONCLUSIONS

European women are frailer and have slightly more comorbidity than European men lending support for the male-female health survival paradox.

Are changes in productive activities of older people associated with changes in their well-being? Results of a longitudinal European study

Using the first two waves from the Survey of Health, Ageing and Retirement in Europe (SHARE) we explore dynamics of participation in two different types of productive activities (voluntary work and care for a person) and test their association with changes in well-being across 11 European countries (N = 10,309) among people aged 50 and older. In order to measure changes in well-being, we use a standardized instrument of quality of life in early old age (CASP-12) and assess relevant decreases and increases between both waves, applying the Edwards-Nunnally method. Main findings demonstrate that older people who maintain or start their productive activity in terms of volunteering between both waves have a lower probability of experiencing a relevant decrease in well-being, while no association with a relevant increase in well-being is observed. In case of caring for a person changes in participation remain unrelated to changes in well-being. These results are maintained after adjusting for important confounders, such as functional limitation, socioeconomic position and living with a partner. These latter conditions were also strongly related to changes in well-being. Our results support a core assumption of the activity theory of ageing claiming that the initiation and maintenance of a productive activity is beneficial for older people's well-being.

The Impact of COVID-19 on Informal Caregiving and Care Receiving Across Europe During the First Phase of the Pandemic

Purpose: We analyzed the effects of COVID-19 as well as its accompanying epidemiological control measures on health-related outcomes (physical and mental health) and unmet care needs of both caregivers and care recipients across Europe and Israel by taking into account country differences. Methods: We applied comparisons of adjusted predictions, controlling for a large set of relevant respondent characteristics, to investigate changes in the physical and mental health of caregivers and care recipients due to COVID-19. Furthermore, multilevel regression models were used to analyze the effect of individual and contextual indicators on the probability of reporting difficulties in receiving care. For the analyses, we used data from 26 countries with 51,983 respondents over 50 years based on the eighth wave of the Survey of Health, Aging and Retirement in Europe (SHARE), which had to be suspended in March 2020, and the SHARE Corona Survey fielded from June to August 2020. Results: During the first phase of the pandemic in spring/summer 2020, the frequency of providing personal care to parents increased in almost all European countries, while care to children, in turn, decreased. Parental caregivers who increased the frequency of providing personal care reported significantly more mental health strains, that is, feeling sad/depressed and anxious/nervous more often since the outbreak of the pandemic. With respect to receiving care, about one out of five care recipients had difficulty in obtaining adequate care from outside the household during the pandemic. The perception of unmet care needs was significantly associated with country differences regarding the duration of the stay-at-home orders. In contrast, the number of confirmed deaths did not have a significant effect on perceiving difficulties related to receiving care. Conclusions: Our findings show the extent of the burden to which caregivers and care recipients were exposed with respect to the unintended consequences of COVID-19-related epidemiological control measures. There is a great need within this population for interventions, which effectively reduce the burden as well as the symptoms of anxiety or depression for caregivers as well as care recipients. This should be recognized by (health) policymakers and social organizations.

Grandparenting, education and subjective well-being of older Europeans

We study whether grandparenthood is associated with older people's subjective well-being (SWB), considering the association with life satisfaction of having grandchildren per se, their number, and of the provision of grandchild care. Older people's education may not only be an important confounder to control for, but also a moderator in the relation between grandparenthood-related variables and SWB. We investigate these issues by adopting a cross-country comparative perspective and using data from the Survey of Health, Ageing and Retirement in Europe covering 20 countries. Our results show that grandparenthood has a stronger positive association with SWB in countries where intensive grandparental childcare is not common and less socially expected. Yet, this result is driven by a negative association between grandparenthood without grandparental childcare and SWB that we only found in countries where intensive grandparental childcare is widespread. Therefore, in accordance with the structural ambivalence theory, we argue that in countries where it is socially expected for grandparents to have a role as providers of childcare, not taking on such a role may negatively influence SWB. However, our results show that grandparental childcare (either intensive or not) is generally associated with higher SWB. Overall, we do not find support for a moderating effect of education. We also do not find striking differences by gender in the association between grandparenthood and SWB. The only noteworthy discrepancy refers to grandmothers being often more satisfied when they provide grandchild care.

Are Loneliness and Social Isolation Associated with Quality of Life in Older Adults? Insights from Northern and Southern Europe

Purpose: Loneliness and social isolation have detrimental effects on health in old age; however, the prospective associations with quality of life (QoL) remain unclear. Furthermore, despite the existence of a European north-south gradient in the distribution of loneliness and social isolation, little is known whether the associations are context-specific. We investigated the relationships between loneliness, social isolation and QoL of older adults residing in the North (Sweden) and South (Spain) of Europe. Methods: Study sample consisted of 2995 Swedish and 4154 Spanish older adults who participated in waves six and seven of the Study on Health, Aging and Retirement in Europe (SHARE). Loneliness and social isolation were measured at the baseline, and QoL was measured at the baseline and follow-up using CASP-12. Prospective associations were assessed via multivariate linear regression. Results: In Sweden, subjects with higher vs. lower loneliness had 1.01 (95% CI: −1.55, −0.40) units lower QoL, while every standard deviation increase in social isolation was associated with a 0.27 (95% CI: −0.42, −0.09)-unit decrease in QoL. In Spain, every standard deviation increase in social isolation was associated with a 0.66 (95% CI: −1.11, −0.22)-unit decrease in QoL. The association was stronger in subjects aged ≤65 years old and those with no chronic diseases. The association with loneliness was not statistically significant in Spain. Conclusion: Loneliness and social isolation are prospectively associated with decreased QoL among older adults, yet the associations are contextually bound. Future interventions should target both exposures, among others, in order to increase QoL in this group.

Variations in preventive care utilisation in Europe

Prevention has been identified as an effective strategy to lead healthy, active and independent lives in old age. Developing effective prevention programs requires understanding the influence of both individual and health system level factors on utilisation of specific services. This study examines the variations in utilisation of preventive services by the population aged 50 and over in 14 European countries, pooling data from the two waves of Survey of Health Ageing and Retirement in Europe and the British Household Panel Survey. The models used allow for the impact of individual level demand-side characteristics and supply-side health systems features to be separately identified. The analysis shows significant variations in preventive care utilisation both within and across European countries. In all countries, controlling for individual health status and country-level systemic differences, higher educated and higher income groups use more preventive services. At the health system level, high public health expenditures and high GP density is associated with a high level of preventive care use, but specialist density does not appear to have any effect. Moreover, payment schemes for GPs and specialists appear to significantly affect the incentives to provide preventive health care. In systems where doctors are paid by fee-for-service the utilisation of all health services, including cancer screening, are higher.

Retirement blues

This paper analyses the short- and longer-term effects of retirement on mental health in ten European countries. It exploits thresholds created by state pension ages in an individual-fixed effects instrumental-variable set-up, borrowing intuitions from the regression-discontinuity design literature, to deal with endogeneity in retirement behaviour. The results display no short-term effects of retirement on mental health, but a large negative longer-term impact. This impact survives a battery of robustness tests, and applies to women and men as well as people of different educational and occupational backgrounds similarly. Overall, the findings suggest that reforms inducing people to postpone retirement are not only important for making pension systems solvent, but with time could also pay a mental health dividend among the elderly and reduce public health care costs.

Who cares? A comparison of informal and formal care provision in Spain, England and the USA

This paper investigates the prevalence of incapacity in performing daily activities and the associations between household composition and availability of family members and receipt of care among older adults with functioning problems in Spain, England and the United States of America (USA). We examine how living arrangements, marital status, child availability, limitations in functioning ability, age and gender affect the probability of receiving formal care and informal care from household members and from others in three countries with different family structures, living arrangements and policies supporting care of the incapacitated. Data sources include the 2006 Survey of Health, Ageing and Retirement in Europe for Spain, the third wave of the English Longitudinal Study of Ageing (2006), and the eighth wave of the USA Health and Retirement Study (2006). Logistic and multinomial logistic regressions are used to estimate the probability of receiving care and the sources of care among persons age 50 and older. The percentage of people with functional limitations receiving care is higher in Spain. More care comes from outside the household in the USA and England than in Spain. The use of formal care among the incapacitated is lowest in the USA and highest in Spain.

Depression and loneliness of older adults in Europe and Israel after the first wave of covid-19

Epidemic control measures that aim to introduce social distancing help to decelerate the spread of the COVID-19 pandemic. However, their consequences in terms of mental well-being might be negative, especially for older adults. While existing studies mainly focus on the time during the first lockdown, we look at the weeks afterward in order to measure the medium-term consequences of the first wave of the pandemic. Using data from the SHARE Corona Survey, we include retired respondents aged 60 and above from 25 European countries plus Israel. Combining SHARE data with macro-data from the Oxford COVID-19 Government Response Tracker allows us to include macro-indicators at the country level, namely the number of deaths per 100,000 and the number of days with stringent epidemic control measures, in addition to individual characteristics. The findings show that both macro-indicators are influential for increased feelings of sadness/depression, but that individual factors are crucial for explaining increased feelings of loneliness in the time after the first lockdown. Models with interaction terms reveal that the included macro-indicators have negative well-being consequences, particularly for the oldest survey participants. Additionally, the results reveal that especially those living alone had a higher risk for increased loneliness in the time after the first COVID-19 wave.

Going formal or informal, who cares? The influence of public long-term care insurance

International differences in long-term care (LTC) use are well documented, but not well understood. Using comparable data from two countries with universal public LTC insurance, the Netherlands and Germany, we examine how institutional differences relate to differences in the choice for informal and formal LTC. Although the overall LTC utilization rate is similar in both countries, use of formal care is more prevalent in the Netherlands and informal care use in Germany. Decomposition of the between-country differences in formal and informal LTC use reveals that these differences are not chiefly the result of differences in population characteristics but mainly derive from differences in the effects of these characteristics that are associated with between-country institutional differences. These findings demonstrate that system features such as eligibility rules and coverage generosity and, indirectly, social preferences can influence the choice between formal and informal care. Less comprehensive coverage also has equity implications: for the poor, access to formal LTC is more difficult in Germany than in the Netherlands.

Retirement and cognitive decline. A longitudinal analysis using SHARE data

We show that a new measure of cognitive decline, that can be computed in longitudinal surveys where respondents perform the same recall memory tests over the years, is highly predictive of the onset of dementia. Using SHARE data, we investigate the way retirement affects cognitive decline over time controlling for age, education and other confounding factors. We find that retirement has a long-term detrimental effect on cognition for individuals who retire at the statutory eligibility age. It plays instead a protective role for those who retire on an early retirement scheme.

Transitions in formal and informal care utilisation amongst older Europeans: the impact of national contexts

The objective of this study was to explore how long-term care systems, and in particular the incorporation of needs-based entitlements to care services or benefits, influence formal and informal care utilisation dynamics. We used the Survey of Health, Ageing and Retirement in Europe (SHARE) wave 1 and 2 data, restricting the sample to persons 65+ from 9 European countries (N = 6,293). The effects of changes in health and household composition on formal and informal care transitions were estimated using logistic regression, allowing these effects to vary across countries. The results indicated that, in all countries, formal and informal care were more often complements than substitutes. The likelihood of becoming a formal or informal care user varied significantly between countries. In the Scandinavian countries and in several continental European countries with needs-based entitlements, the transition to formal care was strongly related to informal support being or becoming unavailable. We found little evidence of country differences in the effect of health variables on the transition to formal care. The analysis suggested that, whilst rates of formal care utilisation continue to differ considerably between European countries, formal care allocation practices are not very dissimilar across Northern and continental European welfare states, as we found evidence for all countries of targeting of older persons living alone and of the most care-dependent older people.

Gendered support to older parents: do welfare states matter?

The aim of this study is to examine the association of welfare state policies and the gendered organisation of intergenerational support (instrumental help and personal care) to older parents. The study distinguishes between support to older parents provided at least weekly, i.e. time-intensive and often burdening support, and supplemental sporadic support. Three policy instruments were expected to be associated with daughters' and sons' support or gender inequality in intergenerational support respectively: (1) professional social services, (2) cash-for-care payments and (3) legal obligations to provide or co-finance care for parents. The analyses based on the Survey of Health, Ageing and Retirement in Europe showed that daughters provided somewhat more sporadic and much more intensive support than sons throughout Europe. While about half of all children who sporadically supported a parent were men, this applied to only one out of four children who provided intensive support. Logistic multilevel models revealed that legal obligations were positively associated with daughters' likelihood of giving intensive support to parents but did not affect the likelihood of sons doing so. Legal obligations thus stimulate support in a gender-specific way. Both legal obligations and cash-for-care schemes were also accompanied by a more unequal distribution of involvement in intensive support at the expense of women. Social services, in contrast, were linked to a lower involvement of daughters in intensive support. In sum, the results suggest that welfare states can both preserve or reduce gender inequality in intergenerational support depending on specific arrangements.
