Screening Across the Lifespan Twin Study (SALT)
The SALT study was initiated in 1998, with the purpose of screening all twins in Sweden born before 1958 for most common complex diseases, regardless of the status of their twin partner. SALT is a sub-study of the Swedish Twin Registry (STR) and it is a complete screening of all twins from this registry, regardless of gender composition or vital status of the pair. In addition to the SALT interview, there was the TwinGene (2004-2008), and SALTY (2009-2010) sub-studies which included questionnaires and biosamples, and HARMONY (1998-2003) which included cognitive functioning screenings for those 65 and above.
