Clinical Trial Summary
Previous research focusing on preschoolers' healthy behaviors looked at developing
interventions for separate behaviors, such as physical activity and sedentary behavior.
Currently, there is a shift in research towards focusing on an integrated approach regarding
the behaviors conducted in a 24-hour day, since targeting multiple behaviors is more
effective. Activities in a 24-hour day consist of physical activity, sedentary behavior and
sleep. Only very few Belgian preschoolers (10%) meet the guidelines regarding a healthy
24-hour day. Therefore, interventions focusing on all three behaviors with an integrated
approach are needed. Since preschool children spend most of their time at school and at home,
and engage in playbased learning in those settings, this project will develop and evaluate an
intervention focusing on those 24-hour behaviors both at school and at home. The aim of the
intervention is to increase the percentage of preschoolers that comply with the guidelines
regarding a 24-hour day. Within the project, we will work closely together with both
preschoolers' teachers and parents to develop and create the intervention, framed within the
Intervention Mapping protocol. The intervention will be evaluated through a cluster
randomized controlled trial, using a pretest, posttest and follow-up. Preschoolers' physical
activity, sedentary behavior and sleep will be measured using an objective measurement device
(accelerometer).
Description:
Research has shown that sufficient physical activity, limiting sedentary behavior (i.e.
sitting or lying down), and adequate sleep yield health benefits in preschoolers. This
resulted in separate health guidelines for preschoolers that recommended 180 minutes of daily
physical activity, spending no more than 1 hour per day sedentary in front of a screen, and
sleeping at least 10h-13h per day (naps during the day included). However, research has shown
that these 3 behaviors are related to each other within the time frame of a 24-hour day.
A day consists of exactly 24 hours that are filled with activities that can be categorized as
physical activity, sedentary behavior or sleep. This implies that a change in one of these
behaviors (e.g. more physical activity) causes a change in the time that can be spent on (one
of) the other two behaviors (e.g. less sedentary and/or less sleep). Recent research has
shown additional health benefits when preschoolers meet more than one of the above
guidelines. For example, more positive health effects are obtained when sedentary behavior is
reduced and replaced by more physical activity while maintaining the hours of sleep per day.
These findings resulted in the integrated 24-hour guidelines for physical activity behavior
distributed by the World Health Organization in 2019. According to these guidelines, a
healthy day for preschoolers consists of (1) at least 180 minutes of physical activity, 60
minutes of which are at moderate to high intensity, (2) a maximum of 1 hour of sedentary
screen time, and (3) 10 to 13 hours of good quality sleep. The greatest health effect is
obtained when children meet all three guidelines.
Evidence showed that only 1 in 10 Belgian preschoolers meet the 24-hour guidelines for
physical activity. Therefore, there is currently a need to develop interventions that focus
on the 3 behaviors simultaneously. In the past, interventions mainly focused on one or two of
these behaviors separately and never aimed for an optimal combination of these 3 behaviors.
The present project will therefore develop, implement and evaluate an intervention to promote
these 3 behaviors through the home and school environment. The goal of the intervention is to
increase the number of preschoolers who achieve the integrated 24-hour movement behavior
guidelines per day. The intervention will be developed based on the Intervention Mapping
protocol, a widely used protocol to develop evidence based behavior change interventions. To
increase the chance of developing a successful intervention, the intervention will be
developed by using a co-creational approach. This is a specific form of collaboration where
stakeholders are involved in the developmental process and the end result of the
intervention. Important stakeholders for the development of preschoolers in this project are
teachers and parents. Co-creation can only be successful if there is equality between the
participants, reciprocity and if is conducted within an atmosphere of openness and
confidence. In order for these conditions to be met, the co-creation process will be
supervised by a researcher. Two co-creation groups will be formed that include both parents
and teachers. Both groups will be composed of 3 to 4 preschool teachers and 3 to 4 parents of
3- to 5-year-old preschoolers. The co-creation groups will go through the first four steps of
the Intervention Mapping protocol together with the researcher. The results of the
co-creation will be compared after each session with the goal of reaching a consensus on the
final intervention in both groups at the end of the process. The intervention will be
composed of easily usable and achievable intervention strategies (e.g. storytelling,
games,...) aimed at the game-based learning of preschoolers in the home and school
environments.
The second objective of this research project is the evaluation of this newly developed,
theory-based intervention. The intervention will be tested via a cluster randomized
controlled trial (RCT) design (as preschools will be the unit of randomization), including an
intervention and control group. The evaluation of the intervention will consist of an effect
evaluation evaluation. We hypothesize that the intervention will lead to a higher percentage
of preschool children complying with these guidelines. The design of the RCT
(pretest-posttest-follow-up, intervention and control group) will allow us to measure the
evolution over time as a result of the intervention.
