Apple Women’s Health Study releases preliminary data : Apple World Today

The Apple Women’s Health Study team at Harvard T.H. Chan School of Public Health has released a preliminary study update, offering pioneering scientific insights on women and their menstrual symptoms, made possible through the research methodology of Apple’s Research app. 

The update, based on a cohort of 10,000 participants and inclusive of varying ages and races across the U.S., highlights how large-scale, longitudinal research on menstruation can help advance the science around women’s health and destigmatize menstruation.

Through the Research app, the Apple Women’s Health Study invites women across the U.S. to contribute to research by using their iPhone, and Apple Watch if they have one. The study allows for collection of a comprehensive set of cycle tracking and other health data, strengthened through participant surveys, from individuals across various stages of their life, varying races, and throughout all US states and territories. Participants control the data types shared with the study, with transparency into how the data will be used for the purposes of the study.

iPhone and Apple Watch users across the US download the Research app to enroll in the study, conducted in partnership with Harvard T.H. Chan School of Public Health and the NIH’s National Institute of Environmental Health Sciences (NIEHS). Participants must be at least 18 years old (at least 19 years old in Alabama and Nebraska and at least 21 years old in Puerto Rico) and have menstruated at least once in their life.
