This book describes key methods and instruments for assessing diet-related factors, physical activity, social and environmental factors, physical characteristics and health-related outcomes in children and adolescents. These tools were developed and deployed within the framework of the pan-European IDEFICS and I.Family cohort studies. These population-based field studies were funded within the 6th and 7th European Framework Programme, respectively, and were intended to assess the prevalence and aetiology of lifestyle-related diseases in children, focusing on overweight and obesity, and to develop effective strategies for primary prevention. In the course of a decade we undertook a major research endeavour, collecting standardised data from children, families, neighbourhoods, kindergartens, pre-schools and schools in eight European countries, employing a uniform cross-cultural methodology. This resulted in a rich picture of the daily lives and living contexts of children and their families.
Studies encompassing childhood and adolescence face the particular challenge of the transitions from pre-school to primary school and from childhood to adolescence; accordingly, the instruments used need to be adapted to different developmental stages while maintaining their comparability across the age range. In young children, questionnaires have to be completed by proxies, usually their parents, while older children, particularly adolescents, can provide a major part of the requested information themselves.
This book presents suitable designs, methods and instruments for data collection in studies of children and adolescents. Each chapter explains the development and background of the instruments applied in the surveys and summarises the current state of knowledge. All chapters were written by key experts in their respective research fields. We are grateful for their valuable contributions and their enthusiastic support in producing this book, which also presents survey experiences in which practice does not always follow theory. Participants' responses can on occasion be unexpected and unpredictable, but meeting these challenges can also enrich epidemiological surveys and yield methodological refinements. We sincerely hope that the book and the online material will be of considerable value to other research teams.
Karin Bammann
Department of Epidemiology of Demographic Change, Institute for Public Health and Nursing Research (IPP), University of Bremen, Germany
Karin Bammann has been a Senior Researcher at the Department of Human and Health Sciences of the University of Bremen since 2011. Her teaching focuses on empirical and epidemiological methods, project management, and lifestyle related diseases. As head of the Department of Epidemiology of Demographic Change at the Institute for Public Health and Nursing Research (IPP), she has extensive experience in conducting and managing epidemiological studies, and in primary data collection. Her research currently concentrates on health and disease during the life course, and on physiological, social and contextual determinants thereof. A second focus is on empirical research methodologies, especially on the application of mixed methods and participatory research methods in Public Health and epidemiology. She was an international scientific manager and responsible for instruments, standardisation and quality management in the largest pan-European children's cohort, including more than 18,000 children, the IDEFICS cohort. She has published more than 80 international peer-reviewed papers, 11 book chapters, and three books.

Iris Pigeot has been a Professor of Statistics with a focus on biometry and methods in epidemiology at the Department of Mathematics and Computer Science, University of Bremen since 2001. She is director of the Leibniz Institute for Prevention Research and Epidemiology - BIPS and head of the Department of Biometry and Data Management. Her research activities focus on bioequivalence studies, graphical models, and genetic epidemiology. In recent years she has broadened the scope of her research to include the use of secondary data in the research of pharmaceutical drug safety as well as primary prevention and its evaluation, especially for childhood obesity. She was deputy coordinator of the largest pan-European children's cohort, including more than 18,000 children, the IDEFICS/I.Family cohort. She has received several teaching awards: the "Medal for Excellent Teaching" at the University of Dortmund in 1994, the "Award for Quality Teaching" at the University of Munich in 1996, and the "Berninghausen Award for Excellent Teaching and its Innovation" at the University of Bremen in 2008. In 2010 the IBS-DR awarded her the Susanne-Dahms medal for special accomplishments in the field of biometry. She has authored or co-authored four books, the most recent being a German textbook "Epidemiological Methods" (Springer 2012), and has edited or co-edited three books, most recently the "Handbook of Epidemiology" (Springer 2014).
