Identification and prevention of dietary- and lifestyle-induced health effects in children and infants - IDEFICS study
Description
- The IDEFICS study started in September 2006 and ended in February 2012. The Bremen Institute for Prevention Research and Social Medicine at the University of Bremen (today Leibniz Institute for Prevention Research and Epidemiology - BIPS) coordinated the study, which was funded by the European Commission under the 6th Framework Programme. The study provided reliable data that allows for an international assessment of the problem of childhood obesity. The focus of the IDEFICS study lied in exploring the risks for overweight and obesity in children as well as associated long-term consequences.
23 renown research institutes and small and medium sized enterprises located in 11 different EU-countries participated in the IDEFICS study. IDEFICS' main goal was to fight overweight, obesity and other lifestyle-related disorders in 2-10-year old European children. One of the focal points of the IDEFICS study lies in exploring the risks for overweight and obesity in children and the associated long-term consequences. In addition, this EU-wide study measured in how far sensory perception and -preferences of children influence the development of overweight.
Beyond pure research, the IDEFICS study offered activities for health promotion and prevention in kindergartens and schools. These prevention programmes were developed, implemented and evaluated within the IDEFICS Study. The results of the study have been embedded into prevention programs and incorporated into various guidelines on nutritional, behavioural and lifestyle as well as ethical guidelines to introduce these into health policy recommendations in all participating countries.
Many children of the IDEFICS study and their families participated in the I.Family study in 2013/2014. Further follow-up studies are being conducted as part of the longitudinal IDEFICS/I.Family cohort.
One additional follow-up took place 2020-2022 in form of a web-based questionnaire to further explore the health and behaviours of the IDEFICS/I.Family cohort participants, many of who had reached an adult age by then.
