KiGGS

KiGGS, short for Kinder- und Jugendgesundheitssurvey, is a national health survey conducted in Germany by the Robert Koch Institute (RKI). It collects information on the health status, health-related behaviors, and determinants of health among children and adolescents in Germany, with the aim of monitoring health trends and informing public health policy.

The study combines interviews or questionnaires, physical examinations, and laboratory measures to assess physical and mental health, growth, obesity, vaccination status, nutrition, physical activity, and environmental exposures. KiGGS is designed to produce nationally representative estimates for the population aged 0 to 17 years at baseline and to support follow-up assessments through subsequent waves.

Timeline and design: KiGGS began with Baseline data collection from 2003 to 2006. It has been followed by longitudinal components and two major waves: KiGGS Wave 1 (approximately 2009–2012) and KiGGS Wave 2 (approximately 2014–2017). The survey uses standardized protocols and engages both parents or guardians and the children or adolescents themselves where appropriate.

Data and dissemination: KiGGS data cover a broad range of health indicators, including obesity, asthma, allergic diseases, mental health, dental health, vaccination coverage, and risk factors such as nutrition and physical activity. Data are weighted to reflect the German youth population and are published in RKI reports, scientific articles, and public health briefs. Access to detailed data is governed by data protection rules and may be available to researchers under applicable approvals.

Impact: KiGGS provides essential evidence for monitoring child and adolescent health in Germany, enabling trend analyses, comparisons across generations, and informed decision-making for health policy and prevention programs.
