Ethics approval and consent to participate
: The study was approved by the Regional Ethical Review Board in Lund (diary no. 2013/15), and the research was performed in accordance with the Declaration of Helsinki (World Medical Association 2013). Both the National Board of Health and Welfare and Statistic Sweden made separate secrecy reviews, and the data were anonymized before being given to the PI (Gerd Ahlström). The study design did not include informed written consent from the participants; instead, information about the study and how to withdraw from it was advertised in two major national newspapers in Sweden. One of these newspapers was published by the Swedish National Association for Persons with Intellectual Disability (FUB). The other was a well-known national newspaper (Dagens Nyheter). No one refused participation.
