L’équipe de la Chaire Aging UP! sera présente aux 47e JESF qui se tiendront du 3 au 5 décembre 2024 à Créteil.
A cette occasion Anais Cheneau et Aimée Kingsada présenteront les résultats de leurs dernières recherches.
Anais Cheneau exposera ses analyses du volet Organisation des soins de l’enquête France : “Caregiving, mental health and familial norms: Evidence from a matched sample of French adult children“. Cheneau A., Sicsic J., Rapp T.
Background: Informal caregivers provide essential support to older adults, yet often face mental-health strain. Whether such strain depends on familial norms remains underexplored.
Methods: Using the 2024 French AgingUp! survey of adults aged 50+, we focus on adult children with at least one living parent (N=1,227; 359 caregivers, 868 non-caregivers). We estimate linear probability and logit models on a propensity-score–matched sample with exact matching on gender, adjusting for socioeconomic and family covariates. Outcomes are four items from the MHI-5 (nervous, downhearted, happy, calm/relaxed). We test moderation by three familial-norm measures and probe endogeneity of norms using logistic models by care duration and intensity.
Results: Caregiving is associated with higher probabilities of feeling nervous (≈+11 pp) and downhearted (≈+10 pp), and lower probabilities of feeling calm/relaxed (≈–13 pp) and happy (≈–8–11 pp). Familial norms moderate these associations: caregivers who endorsed strong family responsibility showed smaller mental-health effects, whereas those agreeing that “children have their own lives” experienced worse mental health effects. These associations persist, though attenuated, after adding health and financial controls.
Conclusions: Mental-health harms of caregiving are substantial and conditioned by norms. Policy should target higher-risk caregivers and align care plans with family preferences, facilitating flexible, gradual and affordable delegation to professionals.

Aimée Kingsada, chercheuse associée au LIRAES-Chaire Aging UP! présentera l’article : “Analyse des préférences des Français pour des programmes de prévention de la perte d’autonomie” à partir des premiers résultats du volet Prévention et Innovation de l’enquête Aging UP! lancée tout récemment.

This study examines preferences for prevention programmes promoting healthy ageing among French adults aged 40–59 using a discrete choice experiment (DCE). A nationally representative sample of 1,526 respondents, all of whom reported lifestyle habits below WHO recommendations, completed ten choice tasks comparing hypothetical prevention programmes varying in duration, delivery mode, follow-up, required effort in physical activity and diet, and monthly cost. Random-effects logit, alternative-specific multinomial logit, and mixed logit models were estimated to assess determinants of programme uptake and preference heterogeneity.
Main results: Five of the six programme attributes significantly influenced choice across all model specifications. Longer programme duration reduced uptake, while individual delivery modes were clearly preferred over group-based options.
Method: Remote follow-up methods (digital or teleconsultation) were generally favoured. Higher levels of required effort—whether in physical activity or dietary modification—decreased participation likelihood, with substantial heterogeneity observed across individuals. Monthly cost exerted the largest and most consistent negative effect on programme choice. Sociodemographic characteristics such as income and occupational status significantly predicted participation, whereas health status and prevention messages had limited influence. Use of digital health devices and positive motivation towards national recommendations substantially increased opt-in behaviour.
Mixed logit results showed substantial unobserved preference heterogeneity, particularly regarding programme modality, physical activity requirements, dietary changes, and cost.
Overall, respondents expressed strong interest in structured prevention programmes, but only when these are affordable, personalized, and impose manageable effort. The findings provide robust quantitative evidence to guide the design of acceptable and effective prevention interventions aligned with population preferences.
Thomas Blavet chercheur associé au LIRAES-Chaire Aging UP! présentera “Long-term care expenditure projections model for OECD countries“.
Background: By 2050, the proportion of the population aged 65 or older is expected to reach 26.7 percent. In this context of an ageing population, the demand for LTC services and related expenditures are expected to increase significantly.
Objective: To assess the change in the share of the health and social components of LTC expenditure from public sources in GDP, we projected expenditures to 2040 and 2050 across OECD countries.
Methods: We used regression analyses to identify drivers and estimate coefficients of the health and social components of LTC spending. We then develop a projection model for OECD countries that are also members of the European Union Statistics on Income and Living Conditions (EU-SILC) survey. We used time series (2003-2022) from the OECD System of Health Accounts (SHA), which provides LTC expenditures for both components, and OECD Statistics for regression analyses. Data from the EU-SILC survey were also used to estimate the proportion of people with disabilities by age group by country. Projections of key drivers were based on the OECD Economic Outlook data.
Results: On average, LTC expenditures from public sources are projected to increase by 0.99 percentage points to 2.13% of GDP for the health component and by 0.68 percentage points to 1.08% of GDP for the social component by 2050, accounting for 3.21% of GDP thereafter.
Conclusions: All countries in this study would need to invest a larger share of their income to provide LTC services.
