The effect of frailty on the relationship between cognition and depression symptoms in older people: a differential analysis by European regions
Publication . de Maio Nascimento, Marcelo; Ihle, Andreas; Gouveia, Elvio; Gonzalez, Ricardo Hugo; Marques, Adilson
This study aimed to investigate the moderating effect of frailty on the relationship between cognition and symptoms of depression in individuals aged ≥65 and to explore differences between four European regions (West, North, South, and East). A cross-sectional analysis was conducted with 29,094 participants (16,365 women) from 27 countries, aged ≥65 years, who responded to wave 8 of the SHARE project. The variables analysed were depression (12-item EURO-D scale), frailty, and a general cognition index (CogId). A higher CogId was associated with less depression. Western and Northern European countries indicated better cognitive performance, lower depression symptomology, and frailty scores than those in the South and East. A pre-frail and frail status was a significant moderator, increasing the association between depression and cognition in the East, South, North, and West regions, respectively. The interaction effects between CogId and frailty were found in the West and East regions. Comparatively, the moderating role of frailty in countries in the Western region differed significantly from those in the North. In turn, countries in the South and East differed from those in the North region. Frailty was a moderator of depression symptoms, increasing its association with cognition. Strategies to prevent frailty are important to reduce the burden of depression and cognitive deficits in Europe.
Ageing and long-term informal care: the reality of two countries in Europe: Denmark and Portugal

The knowledge of long-term informal care is particularly interesting for social and health measures related to ageing. This study aims to analyze how Portugal differs from Denmark regarding long-term informal care, specifically referring to personal care received by older people. A cross-sectional study was developed in Portugal and Denmark through the Survey of Health, Ageing and Retirement in Europe (SHARE) in 2015, with a total of 2891 participants. Descriptive statistics and logistic regressions were performed. The findings suggest a significant association for older people from Portugal who receive long-term informal care from non-household caregivers and household caregivers. Moreover, as they age and are from Portugal, their availability to receive long-term informal care from non-household caregivers increases. Furthermore, older people in Portugal are more likely to receive long-term informal care from a household caregiver. It is important to take a closer look at long-term informal care in both countries and think about healthy ageing policies in the current context of the ageing population. This study provides knowledge about disaggregated health data on ageing in the European region, helping to fill research gaps related to older people.
Residential trajectories across the life course and their association with cognitive functioning in later life
Publication . Orsholits, Dan; Cullati, Stéphane; Cheval, Boris; Ghisletta, Paolo; Oris, Michel; Maurer, Jürgen; Studer, Matthias; Marques, Adilson; Marconcin, Priscila; Gouveia, Elvio; Kliegel, Matthias; Ihle, Andreas
Previous work has found that later life urban-rural differences in cognitive health can be largely explained by indicators of cognitive reserve such as education or occupation. However, previous research concentrated on residence in limited, specific, periods. This study offers a detailed investigation on the association between urban (vs. rural) residence from birth, and cognitive functioning in older age. Using data from the Survey of Health Ageing and Retirement in Europe we created residential trajectories from birth to survey enrolment with a combination of sequence and cluster analysis. Using mixed-effects models, we investigated the association between residential trajectories in early, mid, and later life and three cognitive functioning outcomes: immediate recall, delayed recall, and verbal fluency. In a sample of 38,165 participants, we found that, even after accounting for differences related to education and occupation, rural (vs. urban) residence in early life remained associated with poorer cognitive performance later in life. This suggests that growing up in rural regions leads to a long-term disadvantage in cognitive functioning. Thus, public health policies should consider that urban-rural inequalities in early life may have long-lasting associations with inequalities in cognitive health in old and very old age.
