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. Data were collected 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 began in 1994. Between 2006 and 2008, 2,245 of the 3,302 women that joined SWAN were seen for their tenth 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), Almaeda 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. Though the New Jersey site was still part of the study, data was not collected from this site for the tenth visit. Demographic and background information includes age, language of interview, marital status, household composition, and employment.

Please refer to the P.I. Codebook for additional information on study design.
Site-specific sampling frames were used and encompassed a range of types, including lists of households, telephone numbers, and individual names of women.
Women age 51 through 63, 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.
Response rates: 16,065 completed the screening interview; 3,302 enrolled in the longitudinal study; 2,881 completed the first follow-up visit; 2,748 completed the second follow-up visit; 2,710 completed the third follow-up visit; 2,679 completed the fourth follow-up visit; 2,617 completed the fifth follow-up visit; 2,448 completed the sixth follow-up visit; 2,327 completed the seventh follow-up visit; 2,278 completed the eighth follow-up visit; 2,255 completed the ninth follow-up visit; and 2,245 completed the tenth follow-up visit.
Raw data can be used to create CES-D scores, a perceived stress score, and a social support score. In addition, Positive and Negative Affect Schedule (PANAS) Scores can be derived. The cognitive function tests such as the East Boston Memory Test (both immediate and delayed recall), Symbol Digits Modalities Test, and the Digits Backward Test are also collected. Bioimpedance measures were also collected.

ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
