The Shanghai Women's Health Study (SWHS), a collaborative study by NCI, Vanderbilt University, and the Shanghai Cancer Institute, is a prospective cohort study of approximately 75,000 Chinese women who were recruited between 1997 and 2000. Members of the cohort have been followed through multiple in-person interviews to obtain information on diet, occupational and environmental exposures, and various lifestyle factors. Information from the follow-ups is linked to vital records and the tumor registry to obtain information on disease. Over the years, data and biological samples (blood/buccal cell and urine) collected in the SWHS have been used to evaluate many important etiologic hypotheses and support multiple studies.
