Abstract:
Background and purpose: The lack of effective school-based interventions for
The lack of effective school-based interventions forpreventing obesity in children has caused a call for longer duration of interventions and
better reporting on design and evaluation methodology. The purpose of this paper is to
present the development of the intervention, the design of the effectiveness study and the
test-retest reliability of the main outcome measures in the HEIA-study.
Methods/design: The HEIA-intervention program was developed based on literature
The HEIA-intervention program was developed based on literaturereviews, a social ecological framework and focus groups. The intervention aimed to
increase total physical activity (PA) and consumption of fruit and vegetables, and to
decrease screen time and consumption of sugar-sweetened beverages. The intervention
program consisted of a classroom component including; dietary behaviour lessons,
computer tailoring, fruit/vegetable and PA breaks and posters, and an environmental
component of; active transport campaigns, equipment, suggestions for easy
improvements of schoolyards, inspirational courses for teachers (all with regards to PA),
and facts sheets to parents. The effect of the intervention program is evaluated in a cluster
randomized controlled trial design (intervention=12 schools, control=25 schools)
including process evaluation. Main outcomes include anthropometry, PA, screen time and
consumption of fruit, vegetables and sugar-sweetened beverages. A two week test-retest
study was conducted among 114 pupils. Determinants of the behaviours were assessed.
Similar data were collected from parents. Children's PA was measured objectively by
accelerometers.
Conclusion: The HEIA-study represents a theoretically informed randomized trial
The HEIA-study represents a theoretically informed randomized trialcomprising a comprehensive set of multilevel intervention components with a thorough
evaluation using reliable outcome measures. The study will contribute to a better
understanding of determinants of healthy weight development among young people and
how such determinants can be modified.
