Version V1

The Study of Women's Health Across the Nation (SWAN) is a multi-site longitudinal, epidemiologic study designed to examine the health of women during their middle years. The study examines the physical, biological, psychological, and social changes during this transitional period. The goal of SWAN's research is to help scientists, health care providers and women learn how mid-life experiences affect health and quality of life during aging. The data include questions about doctor visits, medical conditions, medications, treatments, medical procedures, relationships, smoking, and menopause related information such as age at pre-, peri- and post-menopause, self-attitudes, feelings, and common physical problems associated with menopause. The study is co-sponsored by the National Institute on Aging (NIA), the National Institute of Nursing Research (NINR), the National Institutes of Health (NIH), and the NIH Office of Research on Women's Health. The study began in 1994. Between 1997 and 1999, 2,881 of the 3,302 women that joined SWAN were seen for their first follow-up visit. The research centers are located in the following communities: Ypsilanti and Inkster, MI (University of Michigan); Boston, MA (Massachusetts General Hospital); Chicago, IL (Rush Presbyterian-St. Luke's Medical Center); Alameda and Contra Costa County, CA (University of California-Davis and Kaiser Permanente); Los Angeles, CA (University of California-Los Angeles); Hackensack, NJ (Hackensack University Medical Center); and Pittsburgh, PA (University of Pittsburgh). SWAN participants represent five racial/ethnic groups and a variety of backgrounds and cultures.

Using the variable SWANID, this dataset can be linked with the SWAN Cross-Sectional Screener Data (ICPSR 04368), Baseline Data (ICPSR 28762), Visit 2 Data (ICPSR 29401), and Visit 3 Data (ICPSR 29701).

Site-specific sampling frames were used and encompassed a range of types, including lists of households, telephone numbers, and individual names of women.

Longitudinal: Panel

Women age 40 through 55, living in designated geographic areas, with the ability to speak English or other designated languages (Japanese, Cantonese, or Spanish), who had the cognitive ability to provide verbal informed consent, and had membership in a specific site's targeted ethnic group were included within the first SWAN data collection. For the initial data collection, 202,985 sampling units were screened for participation. 34,985 were identified as eligible. 16,065 completed the survey. 3,302 enrolled in the longitudinal survey. 2,881 completed the first follow-up visit.
