The claim does not distinguish between the stock of all current disability pension recipients and the flow of newly granted disability pensions; the official ETK figure (43% mental vs 25% musculoskeletal) most plausibly describes retirement onto a disability pension, but the wording is ambiguous.
A more recent dataset (Ilmarinen, private-sector insured, 2024) shows musculoskeletal diseases (35%) still ahead of mental disorders (29%) among the pensions it granted, indicating the ranking is not uniform across providers.
The exact reference period of the ETK figure could not be confirmed from the search results; if it refers to an earlier year, the most recent data may differ.
The MEP's party (Left Alliance) has an interest in highlighting mental-health-related labour-market exclusion, so the framing should be read with that context in mind.
