Welcome to the website of Prof. Dr. Jessica Kiefte-de Jong. Jessica Kiefte-de Jong is professor of Population Health with emphasis on lifestyle and lifecourse health research and head of research at the Department of Public Health and Primary Care at Leiden University Medical Center. Before her appointment as full professor, she worked at the International Honours College of Leiden University (LUC), The Hague, and at the Department of Epidemiology and Pediatrics at Erasmus Medical Center in Rotterdam, The Netherlands. Her primary research is focused on the role of nutrition and lifestyle on the risk of chronic diseases in different stages of life (eg. during pregnancy, childhood and adulthood) as well as psychosocial and environmental aspects of health behaviour. Jessica became a registered nutritionist at the Amsterdam University of Applied Sciences. After that she obtained her MSc in Public Health Research and Nutrition at the VU University (The Netherlands). In 2012 she obtained a PhD in Early Life Nutrition from the Sophia Children's Hospital/Erasmus Medical Center (The Netherlands). In 2014 and 2016 she was a visiting researcher at Harvard School of Public Health (USA). For further details, see her CV here
Prof. dr. Kiefte-de Jong's research over the past 5 years evolves around two main pillars. The first pillar includes research on the role of nutrition and lifestyle along the life-course (i.e. during pregnancy, childhood and adulthood). Specifically, she studies the health impacts of dietary and lifestyle factors. Since 2014, she is expanding her research line with a second pillar closely related to the field of population health and prevention, related to the sustainability of health behaviour from a psychosocial and environmental perspective, in particular for vulnerable populations. In this context, she is studying environmental determinants (i.e. related to the food environment) and the impact of food insecurity and (adverse) life events (i.e. key transition moments in life) for which she received the Dekker fellowship of the Dutch Heart Foundation to study the concept of teachable moments (i.e. key transition moments in life) towards lifestyle change.
The research of Prof. dr. J.C. Kiefte-de Jong is part of the research line "Prevention, Population Care and Disease Management" at the Department of Public Health and Primary Care at the Leiden University Medical Center. The researchprojects are organized around the theme's "Nutrition and Lifestyle", "Lifecourse" and "Epidemiology". Meet the researchers and their supervisors here:

The videos below are part of a flipped classroom project which was developed in collaboration with the Leiden University Graduate School of Teaching (ICLON) for the course on Introduction to Epidemiology and Global Public Health at Leiden University College. A flipped classroom is a blended learning strategy that reverses the traditional learning where students gain first exposure to new theory outside of class, through short lecture videos, and then class time is used to apply and critically analyze the theories through strategies as case studies, exercises, journal clubs or debates.

January 24, 2020: It was an honor to finally give my inaugural lecture “Health Promotion: Big data versus Small talk”. About how everything along the life course is connected with current societal health challenges and the need to act beyond the traditional boundaries that we are used to in scientific research, medical education as well as health care. Read the full text (in Dutch) here December 2, 2019: : With Lifestyle4Health (TNO/LUMC) we published the scientific bundle on lifestyle medicine. Read it here September 10, 2019 : NRC published an article on our work on food insecurity and teachable moments towards lifestyle change at LUMC. Find it here September 3, 2019 : We had an inspiring conference at our LUMC Campus in The Hague on the essentials of the first 1000 days of life and how policymakers, researchers and health professionals can contribute to a solid start for all children and their parents May, 21, 2019 : Looking forward to contribute to a healthy The Hague by improving lifestyle as part of the National Diabetes Challenge. January 23, 2019: Thanks to the Dekker Fellowship of the Dutch Heart Foundation we will set up the TEACHLIFE project, to study teachable moments towards lifestyle change at the LUMC Campus The Hague.
