The primary aim of the WGHS is to create a comprehensive, fully searchable genome-wide database of more than 360 000 single nucleotide polymorphisms among at least 25 000 initially healthy American women participating in the ongoing Women's Health Study.

Investigations within the WGHS seek to identify relevant patterns of genetic polymorphism that relate to multiple intermediate phenotypes and will also allow exploration of gene-environment and gene-gene interactions as they relate to incident disease states.

Study Timeline

Each colour in the timeline graph below represents a separate Study Population, while each segment in the graph represents a separate Data Collection Event. Clicking on a segment gives more detailed information on a Data Collection Event.

Population

WGHS population

The cohort is composed of participants of the WHS study. The WHS included initially healthy American women, aged 45 years and older, with no previous history of cardiovascular disease, cancer or other major chronic illnesses at baseline in 1992-1995.

Sources of Recruitment

Participants from Existing Studies Women's Health Study
Supplementary Information

All members of the WGHS cohort were participants in the WHS who provided an adequate baseline blood sample for plasma and DNA analysis and who gave consent for blood-based analyses and long-term follow-up.
