The IDEFICS/I.Family cohort data are a valuable resource for research on child and adolescent health in Europe. The dashboard provides insight into 379 variables from these data (a complete overview of all variables can be found here). They can be examined in aggregate form. The dashboard is available to interested parties after a simple registration. If you intend to analyze the data in more detail to answer a scientific question, please submit a data use request.

The accessible variables represent information from several survey waves (T0, T1, T3 and T5). They include:

• demographic information (e.g. age and country)
• anthropometric characteristics (e.g. height and BMI)
• lifestyle variables (e.g. diet and physical activity)
• laboratory values (e.g. glucose)

The analysis results in the tool are not based on the original data, but on synthetic data. Therefore, deviations from the original results are possible. It should also be noted that results based on only a few people are not shown.

Simple counts are possible, as are as many other summary statistics in tabular form. In addition, various plot types such as histograms, bar charts, box plots and special alluvial plots can be generated for data collected at multiple points in time:

1. Aggregation table: An overview of the basic statistical characteristics of the selected variables, which can be grouped by categorical characteristics.
 

2. Bar charts: Visualization of the frequency distribution of categories and other discrete variables. For continuous data, the visualization is a histogram where the number of bins can be selected by the user.

3. Box plots: Representation of the distribution of continuous data with median and quartiles.

4. Alluvial plots: Visualization of the changes of a discrete characteristic across the different study waves.
