Welcome to the SWAN Repository

The SWAN Study

The Study of Womens Health Across the Nation (SWAN) is an active multi-site, multi-disciplinary, longitudinal study of women’s health. Initially funded in 1994 by the NIA, NINR, and ORWH, the overall goal of SWAN is to describe the biological, behavioral, and psychosocial characteristics that of women during midlife and the menopausal transition. SWAN focuses on the impact of menopause on age-related chronic diseases, such as diabetes, cardiovascular disease, depression, bone loss and osteoporosis, as well as physical and cognitive functioning.

The SWAN Population

SWAN has seven clinical study sites located in six states, two in California, and one each in Chicago, Boston, Detroit area, northern New Jersey and Pittsburgh. The SWAN cohort was recruited from these areas and enrolled in 1996-97 and consists of 3,302 African American, Caucasian, Chinese American, Hispanic and Japanese American women. Cohort members were pre-menopausal, not taking hormones and between 42–52 years of age at the time of enrollment. SWAN participants are seen annually or bi-annually for clinic visits, which include interviews, measurements, and the collection of blood and urine samples. SWAN participants have now been seen for the baseline and 13 follow-up visits.

The SWAN Repository — Resources available to you

The SWAN Repository is the biospecimen bank of the SWAN study. All stored specimens are from the 3,302 SWAN participants. There are currently nearly 1.8 million samples, collected across the 14 annual follow-up visits. Both SWAN Specimens and Data are available to the scientific community.

  • Available Biospecimens include Serum, Plasma, and Urine from annual follow-up visits, as well as DNA and Immortilized Cell Lines on approximately 1500 SWAN participants. Also, a subset of 800 women have provided daily urine samples during one menstrual cycle each year until reaching menopause. This collection is known as the Daily Hormone Study (DHS).
  • SWAN Data *: Nearly 20,000 variables have been collected over the life of the SWAN study, and have been organized in a searchable directory in our Data Warehouse *. Registered users are able to search variables, assemble lists, and save personal libraries. Once a data request is approved, the saved variable libraries can be constructed into datasets and sent to you.
