Child Health and Development Studies (CHDS)
The CHDS aims to investigate how health and disease are passed on between generations. Between 1959 and 1966, over 15,000 pregnant women who were members of the Kaiser Foundation Health Plan in California were recruited. Data was collected from mothers during pregnancy, and the CHDS has continued to follow these mothers and their offspring over multiple time points across development. Data collection is ongoing, and data is currently being collected from a third generation of participants (CHDS grandchildren). The CHDS is involved in a variety of sub-projects.
