Mode Equivalence of Health Indicators Between Data Collection Modes and Mixed-Mode Survey Designs in Population-Based Health Interview Surveys for Children and Adolescents: Methodological Study.

Background: The implementation of an Internet option in an existing public health interview survey using a mixed-mode design is attractive because of lower costs and faster data availability. Additionally, mixed-mode surveys can increase response rates and improve sample composition. However, mixed-mode designs can increase the risk of measurement error (mode effects).

[Quality standards for epidemiologic cohort studies : An evaluated catalogue of requirements for the conduct and preparation of cohort studies].

Background: Cohort studies are a longitudinal observational study type. They are firmly established within epidemiology to assess the course of diseases and risk factors. Yet, standards to describe and evaluate quality characteristics of cohort studies need further development.

EsKiMo II - the Eating study as a KiGGS Module in KiGGS Wave 2.

Nutrition plays an important role for health, in particular of children and adolescents. In addition to the baseline German Health Interview and Examination Survey for Children and Adolescents (KiGGS, 2003-2006), the nutrition survey EsKiMo (Eating study as a KiGGS Module) assessed the dietary habits of children and adolescents aged 6 to 17 in detail. In KiGGS Wave 2 (2014-2017) the corresponding module is EsKiMo II.

New data for action. Data collection for KiGGS Wave 2 has been completed.

The fieldwork of the second follow-up to the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) was completed in August 2017. KiGGS is part of the Robert Koch Institute's Federal Health Monitoring. The study consists of the KiGGS cross-sectional component (a nationally representative, periodic cross-sectional survey of children and adolescents aged between 0 and 17) and the KiGGS cohort (the follow-up into adulthood of participants who took part in the KiGGS baseline study).

[Nutrition, physical activity and substance use in children and adolescents : Representative results of the federal state module Thuringia in KiGGS wave 1].

The term health behaviour combines both health-promoting and health-risk components. In this study, the health behaviour of children and adolescents in Thuringia is analysed. The database was a representative subsample of the federal state module Thuringia, which was conducted by the Robert Koch Institute as part of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) wave 1 (2010-2012; n = 4,096; 3-17 years).

[Medical and inpatient care in childhood and adolescence : Representative results of the federal state module Thuringia in KiGGS wave 1].

At a young age, health care is mainly provided by doctors in private practice. In this study, the health care of children and adolescents in Thuringia is analysed. Data base is the federal state module Thuringia (2010-2012, n = 4884; 0-17 years), which was conducted by the Robert Koch Institute as part of KiGGS wave 1 (2009-2012).

Sample selection, recruitment and participation rates in health examination surveys in Europe--experience from seven national surveys.

Background: Health examination surveys (HESs), carried out in Europe since the 1950's, provide valuable information about the general population's health for health monitoring, policy making, and research. Survey participation rates, important for representativeness, have been falling. International comparisons are hampered by differing exclusion criteria and definitions for non-response.

Public perceptions of cohort studies and biobanks in Germany.

Cohort studies and biobank projects have led to public discussions in several European countries in the past. In Germany, many medium-sized studies are currently running successfully in terms of respondent rates. However, EU-wide research on general public perceptions of biobanks and cohort studies have shown that Germany is among those countries where people express the highest reluctance for providing body material and other data for research purposes.

German health interview and examination survey for adults (DEGS) - design, objectives and implementation of the first data collection wave.

Background: The German Health Interview and Examination Survey for Adults (DEGS) is part of the recently established national health monitoring conducted by the Robert Koch Institute. DEGS combines a nationally representative periodic health survey and a longitudinal study based on follow-up of survey participants. Funding is provided by the German Ministry of Health and supplemented for specific research topics from other sources.

The challenge of comprehensively mapping children's health in a nation-wide health survey: design of the German KiGGS-Study.

Background: From May 2003 to May 2006, the Robert Koch Institute conducted the German Health Interview and Examination Survey for Children and Adolescents (KiGGS). Aim of this first nationwide interview and examination survey was to collect comprehensive data on the health status of children and adolescents aged 0 to 17 years.

Methods/design: Participants were enrolled in two steps: first, 167 study locations (sample points) were chosen; second, subjects were randomly selected from the official registers of local residents.

The costs of atopy and asthma in children: assessment of direct costs and their determinants in a birth cohort.

The aim of this study was to estimate costs accrued by the health care of children with asthma in comparison to children with atopic eczema and seasonal rhinitis and to investigate cost determinants. From the multicenter cohort study (MAS-90), we selected children with an asthma, atopic eczema and/or seasonal rhinitis diagnosis during the first 8 years of life, and overall 8-year health care utilization was estimated retrospectively by reviewing medical records. Asthma treatment (n = 76) incurs an average cost of 627 US dollars per year, 44% due to hospital stays.

Evaluation of a parental training program for the management of childhood atopic dermatitis.

Atopic dermatitis (AD) in childhood is a common disease with prevalence rates as high as 20%. Its early onset in infancy and its chronic relapsing course puts a special burden on families. Supporting parents in dealing with the management of AD presents a challenge for physicians.
