DO-HEALTH is supported by 3 Advisors/Collaborators from Boston, Harvard School of Public Health, and Tufts University


Prof. Bess Dawson-Hughes, MD 

Director, Bone and Mineral Laboratory, Human Nutrition Research Centre on Aging, Tufts University, Boston, USA.

Prof. Dawson-Hughes is the current Secretariat General of the International Osteoporosis Foundation (IOF), and supports DO-HEALTH with her extensive experience in fall and fracture prevention at older age, vitamin D, calcium, diet evaluation, and acid load analyses. Prof. Dawson-Hughes is a longstanding collaborator of Prof. Bischoff-Ferrari since 2002 and Prof. Bischoff-Ferrari is a visiting Scientist at the Human Research Centre on Aging and Nutrition at Tufts University. Prof. Dawson-Hughes collaborated in all pilot studies of DO-HEALTH.

Prof. Walter C. Willett, MD, DrPH

Fredrick John Stare Professor of Epidemiology and Nutrition and Chair, Department of Nutrition, Harvard School of Public Health, Boston, USA

Prof. Walter Willett is the PI of the Nurses Health Study, created and validated the most widely used food frequency questionnaire in the US, and his textbook on nutritional epidemiology is the classic tool used worldwide to teach diet evaluation methodology and the relation between diet and long-term health and disease. Heike Bischoff-Ferrari was a doctoral student of Prof. Willett from 2002 to 2008, and Prof. Willett collaborated on several of the pilot studies of DO-HEALTH. Prof. Willett will support DO-HEALTH with his large expertise on nutritional epidemiology, his expertise in omega-3 fats and vitamin D and the impact of these nutrients on cardio-vascular and general health. Prof. Willett is also a key collaborator within an ancillary study to DO-HEALTH, which aims to create and validate the DO-HEALTH FFQ (food frequency questionnaire).

Prof. JoAnn E. Manson, MD

Chief of Preventive Medicine, Brigham and Women’s Hospital and Harvard Medical School, Boston, USA.

Prof. Manson is a Co-Investigator of the WHI trial and PI of the VITAL trial. She supports DO-HEALTH with her expertise in the design and conduct of large clinical trials, cardiovascular health, cancer, diabetes, and nutrition. DO-HEALTH has been designed as a complementary trial to the NIH-sponsored VITAL trial for 2 of the 3 interventions tested in DO-HEALTH (vitamin D and omega-3). Dr. JoAnn Manson, PI of VITAL and advisor to DO-HEALTH, agreed to collaborate across both studies to enhance their individual value and compare the effects of the individual treatments in the US and Europe. For this, endpoints will be assessed consistently between the two trials for a direct comparison of effects (pooled analysis). DO-HEALTH / VITAL will collaborate to exploit the available data from both studies jointly after the main results have been analyzed for both trials separately. This will further enhance the impact of DO-HEALTH at the public health and global level.
