The overall aim of GECKO-Drenthe is to study the early risk factors, inlcuding physical, genetic and environmental factors, of developing overweight and obesity, with special attention for nutrition and physical activity.

Specific research questions for the first years of life include:
- What is the distribution of anthropometric measures at birth? What are its predicotrs?
- How do anthropometric measures change during the first year of life? Can these changes be explained by mother and/or child factors?
- What are the body fat distribution (ultrasound) and body composition in the first year of life. These measurements will take place in a sample of the total population.

The current project is targeted to the first year of life, but the follow-up will be extended until adulthood or even longer. The details of this follow-up will depend on additional funding.
