Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study will evaluate a coherent model of family support including school health care, primary health care and pediatric clinics. The model combines two evidence based programs: the universal "A Healthy School Start" provided to all children and their families during grade 1 and the targeted parental support program "More and Less" provided to parents of children with overweight or obesity.

The hypothesis is that combining the Healthy School Start and More and Less programs in a coherent model will increase the collaboration between regional and municipal stakeholders, ensure early identification of families in need, ultimately improving prevention and treatment of childhood overweight and obesity. The aim of this study is to evaluate the implementation of a coherent model of family support provided through school and primary health care.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this hybrid type 2 effectiveness-implementation study, a two-armed randomized controlled trial will randomize families to either the intervention arm receiving the More and Less program or the control arm receiving standard care from primary health care or a pediatric clinic. A matched control group will be identified from a national obesity register for supplementary comparison. Eligible participants are families with children aged 6-12 years with overweight or obesity, enrolled in schools implementing the Healthy School Start program. Effectiveness outcomes to evaluate the intervention are BMI z-score, parental feeding practices, diet and physical activity, child eating behaviour and intervention fidelity which will be measured at baseline, three and 12 months. Implementation outcomes will be evaluated in a process evaluation assessing reach, fidelity, acceptability, feasibility and cost, assessed at 12 and 24 months using a mixed methods approach.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

A hybrid type 2 effectiveness-implementation study will evaluate the effectiveness through a randomized controlled trial with two parallel arms and the implementation through a process evaluation. In addition, a register based control group receiving standard treatment will be collected retrospectively to allow for a national comparison.
