Background: As the population is ageing, the need for informal caregivers increases, and thus we need to know more about the effects on caregivers. This study aims to determine both cross-sectional and longitudinal associations between perceived limitation of informal caregiving and mental health of caregivers. Methods: This population-based cohort study was based on the Swedish Psykisk hälsa, Arbete och RelaTioner (PART) study, and 9346 individuals aged 18–65 were included. Data were collected through questionnaires, interviews and Swedish registers.
