Announcing the Birth Control and Blood Clot Study

Print Friendly, PDF & Email

Lucine Health Sciences and Hormones Matter are pleased to announce an important new research project to investigate the relationship between hormonal birth control and blood clots.

Women who use hormonal contraception are at higher risk of developing a blood clot. Although some risk factors are well-documented, such as a family history of blood clots, increasing age, and smoking, many women who have suffered blood clots while on hormonal contraception have none of these risk factors. We believe that a deeper understanding of additional medical and lifestyle influences is crucial to providing women with a complete picture of their personal risk for blood clots while taking hormonal birth control. The Birth Control and Blood Clots Study is multi-phased project designed to assess the breadth and depth of blood clot risks and other side effects associated with these medications.

About the Birth Control and Blood Clots Study

Who Should Participate in the Birth Control and Blood Clots Study? Any woman who has developed a blood clot while on any form of hormonal birth control should participate in the research project. This includes birth control pills, patches, rings, implants, and the Mirena and Skyla IUDs. Because of the severity of some blood clots, including death or serious disability, we allow parents, family members, or partners to take the survey for the affected individual.

How Long Does the Birth Control and Blood Clots Study Take?  This phase of the study involves three parts, an online survey, a participant-submitted health story and an interview with a research associate. The survey portion takes approximately 15-20 minutes to complete. Depending upon one’s comfort with writing, the story portion may take up to few hours. The story portion can be completed at your leisure, however, and may be submitted separately. The interview will take approximately 20 t0 30 minutes.

Is The Study Confidential? Yes, your personal and medical information from the survey will be kept confidential and only study researchers will have access to it. However, unlike our previous studies, this project involves sharing a personal health story in addition to taking a survey. This story will be published on Hormones Matter (the publication can be anonymous if you prefer).  The story of your blood clot experience will serve to inform other women about the risks of blood clots and provide clues for future research.

How Will the Data be Used? The results will be published on Hormones Matter and in open access medical journals in order to inform future research and women’s health decision-making.

Who is Conducting this Research? Researchers from Lucine Health Sciences, the parent company of Hormones Matter. For more information on Lucine, click here.
