Longitudinal Study of Generations (LSOG)
LSOG is a multigenerational study which originally consisted of three generations of family members: over 500 first generation grandparents, over 700 second generation parents, and over 800 third generation grandchildren. Families were recruited from the Greater Los Angeles area, when grandparents with at least one grandchild between 16-26 years of age were drawn randomly from members of a California health maintenance organisation. A fourth generation consisting of over 150 great grandchildren was added to the cohort in 1991, whilst in 2022 recruitment began for the fifth generation great-great grandchildren.
