A variable describing the race of participants (RACE) was added from the Screener dataset.
The race/ethnicity of one participant was originally mislabeled and has now been corrected. Race fields now read Caucasian, not Black, for this participant.
Variables STATUS0 and LMPDAY0 has been updated from another source that evaluated the menopause status related variables over time and corrected inconsistencies.
For the Self-Administered Questionnaire Part A: The variable OVERHLT0 was renamed to HLTHAYR0 to correspond with the same variable asked at later visits. The variable FEARFUL0 was renamed to FEARFULA0 so there is no longer a duplication with a different questionnaire item.
For the Self-Administered Questionnaire Part B: Completion dates were corrected for 6 participants. The variable PREGNAN0 was renamed GETPREG0 so there is no longer a duplication with a different questionnaire item. The variable TIRED0 was renamed to NOTIRED0 so there is no longer duplication with a different questionnaire item. 34 cases were removed as their entire questionnaire was left blank or refused all items.
Lower limit of detection ranges were updated in the Serum Hormone Measures variables.
Spine bone mineral density measures changed for 51 participants.
Missing values have been adjusted from alphanumeric characters to negative numbers.

2014-02-04 This data collection is now publicly available.
2011-01-06 The data for two variables within this dataset, SHBG0 and FSH0, have been corrected so that the proper values are now present within the dataset.
2010-09-02 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. 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:
- Created variable labels and/or value labels.
- Checked for undocumented or out-of-range codes.
Summary View help for Summary
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 1996 and 1997, 3,302 participants joined SWAN through 7 designated research centers. 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. This is the next phase of data collection after the original collection of the screening data (ICPSR 4368).

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.
