The Swedish Twin project of Disability pension and Sickness absence (STODS)

In the STODS project, the aim is to gain increased and more detailed knowledge about risk factors for receiving sick-leave benefits and disability pension, and about potential adverse outcomes of being sickness absent.

In most studies on sickness absence and disability pension one can question to what extent the results are related to selection mechanisms. Using twin data is one way to handle this and this is why we do several studies based on data from twins in combination with other national register data.
