About
Childhood obesity has been associated with increased risk of both continued excess body weight, development of non-communicable lifestyle diseases and impaired mental health.
Approximately 800 children with obesity were treated with a municipality based family-centered lifestyle intervention in the time period 2010-2020. In the same time period, approximately 2000 children with obesity who did not receive any treatment have been identified.
Our aim is to investigate the efficiency of the two interventions and compare those to children not receiving any treatment. We will use data from both the clinical visits at the municipality health care workers and data from Statistics Denmark.
Full description
Childhood obesity often track into adolescence and adulthood resulting in elevated risk of non-communicable lifestyle diseases (e.g. type 2 diabetes). Furthermore, children with obesity are also at risk for impaired mental health (i.e. reduced cognitive function and happiness) and psychological ill-being (i.e. depression, anxiety) compared to their lean peers. Finding methods to efficiently, and in a sustainable way, to treat childhood overweight or obesity has not yet been described.
The aim of this study is therefore to investigate the long term effects of two well established lifestyle interventions on weight development (BMI z-score) and to compare socioeconomic parameters between the intervention groups and children who did not received treatment.
The interventions:
The Aarhus protocol: A multicomponent family-centered lifestyle intervention including visits at home and an opportunity for weekly supervised training. The duration of the intervention was a maximum of one year. Data is available from January 2010.
The Randers Protocol: A multicomponent family-centered lifestyle intervention including repeated visits (up to 8 times each year). The duration of the intervention was a maximum of three years. Data is available from January 2014.
The participants:
Inclusion criteria were children aged 4-18 years with obesity (BMI z-score above the 99. percentile for gender and age) living in Aarhus or Randers municipality.
Between 2010-2020, the following children were included in this trial:
- app. 500 children treated with the Aarhus Protocol,
- app. 300 children treated with the Randers Protocol and
- app. 2000 children in Aarhus who did not participate in a lifestyle intervention delivered by the municipality.
The children were examined routinely (a minimum of three times during elementary school) by the school nurse and anthropometrics were collected in NOVAX. NOVAX is a broadly used IT system which stores and delivers data on childhood anthropometrics to the national the database.
Data collection & analyses:
The weight development will be assessed using data from the municipality and data from the NOVAX. Socioeconomic status will be assessed using register data from Statistics Denmark.
Ethics & permissions:
The local committee on health ethics have approved the overall project and data transfer (rec.no 1-45-70-27-2) The project is internally reported to the University of Aarhus (rec no. 2596) The project has achieved approval from The Danish Data Protection Agency and the Principal Investigator has been granted accessed to data from registers from Danish Statistics.
The project has been reported to ClinicalTrials.gov. The researchers have no conflict of interest to declare.
