Sammanfattning
Aims: The age of retirement has financial implications as we tend to live longer, with the result
that an increasing number of older inhabitants have to share limited financial resources. However,
this is not only a financial issue. It is also of interest to investigate factors related to health and
quality of life associated with the age of retirement. The aim of this study was to investigate changes
in mood, activity level, and cognition at the age of 66 associated with leaving working life before 60.
Methods: Baseline and follow-up data on 840 participants of the Swedish National Study on Aging
and Care – Blekinge was used. Mood was measured by the Montgomery–Åsberg Depression Scale
and activity level by 27 survey items. Cognition was measured by the Mini Mental State
Examination. Results: Retirement before 60 years of age was not associated with lower cognitive
functions and a higher score on depression at baseline, but retirees were less active. Six years later,
at the age of 66, a decline in their cognition was found. Retirees were still not more depressed but
less active. In a logistic regression analysis, being retired increased the odds ratio for cognitive
decline by 1.36-times (OR 2.36) when gender, activity level, education level, and depression were
adjusted for. Conclusions: Participants who retired before the age of 60 declined in cognitive ability
over the 6-year study period.
