Biography

Welcome to the website of Dr. Jessica Kiefte-de Jong. Jessica Kiefte-de Jong is an Assistant Professor in Nutrition and Public Health. She works 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 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 public health nutrition. 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 please see her CV here

  • Research Projects

    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 along the life-course (i.e. during pregnancy, childhood and adulthood) and chronic diseases with specific reference to gastrointestinal diseases and cancer. Specifically, she studies dietary patterns since these are more informative than studying individual foods, because it reflects the real-life situation of a combination of foods that people eat instead of specific products that are rarely eaten in isolation. This approach can therefore be translated into public health messages much more effectively, for example by formulating guidelines that address actual dietary patterns and how to change them. The projects are embedded in the Rotterdam Study, a population-based prospective cohort study among middle-aged and elderly, as well as in the Generation R Study, a population-based birth cohort. In 2014 and 2016, she visited the Harvard School of Public Health in Boston USA to study the diet-dependent acid load hypothesis. Also, she is involved in several international consortia on projects on diet and non-communicable diseases such as within the Consortium on Health and Ageing: Network of Cohorts in Europe and the United States (CHANCES) and Cohorts for Heart and Aging Research in Genomic Epidemiology (CHARGE, Gene-nutrient interactions). Since 2014, she is expanding her research line with a second pillar closely related to the field of public health nutrition, related to the sustainability of diets from a psychosocial and environmental perspective. Together with her colleagues in environmental sciences at LUC, she is studying the environmental impact of global dietary patterns and dietary guidelines, an area of high societal importance. Recently she received a grant from the municipality The Hague to clarify the extent of food insecurity and diet-related diseases in disadvantaged families in close collaboration with the LUMC Campus The Hague. Dr. Kiefte-de Jong has supervised more than 25 MSc students and 6 PhD students and she is currently co-promotor of 4 PhD students. She is (co-)author of more than 100 articles published in international peer-reviewed journals.

    Flipped classroom

    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.
