Understanding the interplay of genes and environments in U.S. families to improve child health: Evidence from the Panel Study of Income Dynamics

Research Project Description

The University of Michigan (U-M) team on this project will lead the effort to collect saliva samples for other adult family members in households that are participating in the 2019 wave of the Child Development Supplement (CDS-2019) to the Panel Study of Income Dynamics (PSID). As part of CDS-2019, and with funding support from the Eunice Kennedy Shriver National Institute of Child Health and Human Development, we plan to collect saliva samples for subsequent genotyping from all children in CDS-2019 as well as their primary caregivers (PCGs).

The scope of work for this project is to expand the collection of saliva samples to include other adult family members for subsequent genotyping. These family members include the other parent of the CDS-2019 children (PCGs are typically the children's mother), adult siblings of the CDS-2019 children, and other relatives such as grandparents. Substantial information is available on these other family unit members from the on-going Core PSID which collects data biennially on these families. The workscope will include identifying eligible family members, the marginal costs associated with visits to the sample households and collection of saliva samples using Oragene DNA Genotek saliva kits, and returning the saliva collection kits to Ann Arbor for processing and storage. We plan to collect salvia samples for approximately 2,859 additional adult residents from 2,622 sampled CDS-2019 households with a response rate of 65%.
