One of the primary objectives of the IDEFICS study was to develop, implement and evaluate a setting-based community-oriented intervention programme in 2- to 9.9-year-old children in eight European countries (Belgium, Cyprus, Estonia, Germany, Hungary, Italy, Spain and Sweden). The baseline survey (T0)(see page “Study design & data collection”) took place in the intervention and control regions selected in these countries, enabling researchers to assess and describe the status quo of health and dietary and lifestyle habits of children in Europe taking into consideration regional, social, biological, and gender specific aspects. After this phase, the primary prevention programme was implemented only in the selected intervention regions, in which activities were offered for health promotion and prevention in kindergartens and schools. The short-term effects of the intervention were assessed during the second survey (T1) 2 years later, repeating the same examinations in children from both, the control and intervention areas, for comparison between both regions. A mailed questionnaire was completed by parents at T2 to assess the sustainability of the intervention.
Timeline of the major study components
(T0 = baseline survey; T1 = full follow-up; T2 = mail survey)
The intervention was designed to address key obesity-related behaviours (diet, physical activity and stress) in 4 levels: individual (children), family (parents), schools and community. Six messages, related to these behaviours were delivered through 10 modules targeted across all the levels.

The different IDEFICS intervention modules can be briefly described as follows, according to their intervention level:
