Challenges related to self-assessment of active ageing during the Covid-19 pandemic in Sweden.

For four items (Participating in events, Exercising, Maintaining friendships, Getting to know new people), recurrent comments indicated that respondents had been affected by the pandemic situation regarding one or more of the facets in UJACAS: will to act, ability to act, opportunity to act, or frequency or extent of doing the activity. Opportunities to act was most frequently commented on as a factor affected by restricted participation in activities. As Prospective RELOC-AGE is a longitudinal study focused on associations between housing, relocation and active ageing, it is imperative to consider the potential pandemic-related impact on baseline data in future analyses.
