Education and career
Wyshak graduated from Smith College in 1949,[1] and from Harvard University in 1956.[2] She earned her Ph.D. in public health (biometry) from Yale University.[3] From 1975, Wyshak was an associate professor in public health at Yale University.[4][5] At Harvard University she served in the Department of Social Medicine and Health Policy.[6] She was also a corresponding member of the Faculty of Psychiatry in the Cambridge Health Alliance, a Harvard-affiliated teaching hospital in Cambridge.[7] From 2022, Wyshak was a senior scientist at the Harvard T.H. Chan School of Public Health.[8]
Research
Wyshak's epidemiological research helped clarify observed relationships between physical activity (exercise) and reduced breast cancer and depression risks.[9] While at Yale, Wyshak used twins as a model to examine survival statistics for twins[10] and to examine inheritance of genes.[11] She also investigated people's willingness to engage in risky behavior, a topic she examined based on a comparison between doctors and lawyers.[12]
Wyshak and Rose Frisch's collaborative work determined that exercise reduced risk of certain cancers,[13] and that drinking carbonated beverages increased the likelihood of bone fractures in young girls.[14][15] Wyshak went on to investigate the link between soda consumption by adolescent girls and bone fractures,[16] research that was broadly covered by the media.[17][18] Her research also demonstrated that female athletes have a reduced risk of breast cancer in their later years,[19] she uncovered historical shifts in the age of menstruation for girls,[20][21] and examined delayed menstruation in young ballerinas.[22][23]
