DOERAK study: Children with obesity in primary care

DOERAK is a prospective cohort study with 2 year follow-up of 733 children in primary care to gain more insight in childhood obesity in primary care.

What we do

About our project

Children with overweight and obesity have a high risk of developing diseases. We want to gain more insight in health related problems of children with overweight in primary care.

Design: prospective cohort study
Population: 733 children (2 - 18 years of age); 18% overweight, 82% non-overweight.
Procedure: Children consulting the GP were included and anthropometry was measured. Number of consultations and accompanying diagnoses during the 2 year follow-up were registered. Children and parents filled out questionnaires including demographics, complaints, quality of life and physical activity and dietary behaviour at baseline, 6, 12 and 24 months. Additionally, children kept a physical activity diary during the baseline week, which was validated in a subsample with an activity monitor.

Our research focus

Primary outcomes

  1. Determinants of persistent overweight in children in primary care
  2. Policy of the GP in children with overweight / obesity?
  3. Quality of life

Secondary outcome
