The Stockholm Birth Cohort Study (SBC) was created in 2004/2005 by a probability matching of two comprehensive and longitudinal datasets. The first, the Stockholm Metropolitan study 19531985, consists of all children born in 1953 and living in the Stockholm metropolitan area in 1963. The second, The Swedish Work and Mortality Database 19802009 (WMD), consists of all individuals living in Sweden in 1980 or 1990, and born before 1985. The initiative to create the database was taken by Denny Vågerö at the Centre for Health Equity Studies, CHESS, of Stockholm University/Karolinska Institute and Sten-Åke Stenberg at the Swedish Institute for Social Research, Stockholm University (SOFI). The resulting database provides a 50-year long follow-up of the original 1953 birth cohort.

The Uppsala Birth Cohort Multigeneration Study (UBCoS) started in 2005 when we were first able to combine existing data on a representative and well-defined cohort of 14,192 males and females born in Uppsala from 1915-1929 (the Uppsala Birth Cohort: UBCoS) with information on descendants of the original cohort members obtained from routine registers.
In 2007-2011, the study was further developed by additional data collection in school archives and records from Census 1930 and the period of follow-up was extended till end of year 2009.
The study is unique in investigating intergenerational effects as “forward in time” processes, starting at the beginning of the last century (i.e. well before any of the routine registers were in place). Intergenerational associations can be currently investigated in more than 140,000 study subjects from families spanning up to five generations, including the 14,192 original cohort members, their 22,559 children, 38,771 grandchildren and 25,471 great grandchildren born up to 2009.
