Move ARound And Get Active: an Intervention to Optimize 24-hour Movement Behaviours in Preschoolers

Move ARound And Get Active: an Intervention to Optimize 24-hour Movement Behaviours in Preschoolers

In 2019, the World Health Organization established new guidelines for physical activity, sedentary screen time, and sleep for children under 5 years old. Unfortunately, only a few (6%) of preschoolers in Flanders, Belgium, adhere to these guidelines. The aim of this study is to test a health program developed to optimize 24-hour behaviors in preschoolers and encourage more children to follow the guidelines. The program was created using the Intervention Mapping Protocol in collaboration with parents. It consists of seven sessions for parents and preschoolers, providing strategies to encourage compliance with the guidelines. The program's effectiveness will be evaluated through a randomized controlled trial, with the intervention group attending the sessions and the control group receiving the intervention materials at the end of the study.

In 2019, the World Health Organization (WHO) established new guidelines for physical activity, sedentary screen behavior, and sleep in children under 5 years old (WHO, 2019). Unfortunately, only a few (6%) preschoolers in Flanders, Belgium, adhere to these guidelines (De Craemer et al., 2018). The objective of this study is to test a health program developed to optimize 24-hour behaviors in preschoolers and encourage more children to adhere to the guidelines. The program was developed using the Intervention Mapping Protocol, in collaboration with parents (Bartholomew, 2011). The program consists of seven sessions for parents and preschoolers, providing strategies to encourage adherence to the guidelines through parenting skills within the framework of self-determination theory (Di Pasquale et al., 2018). The program will be evaluated through a randomized controlled trial. The intervention group will attend the sessions, while the control group will receive the intervention materials at the end of the study.

Aims:

The primary aim is to analyze the intervention effect on 24-hour movement behaviors:

1. Do more preschoolers comply with the World Health Organization 24-hour movement behavior guidelines?

2. Is there an optimal change in the 24-hour composition of preschoolers (i.e., more physical activity, less screen time, and/or more sufficient sleep relative to each other)?

   The secondary aims are:

3. To analyze the intervention effect on parenting within the self-determination theory: Do parents provide more structure, autonomy support, and positive involvement?

4. Process evaluation of the intervention: Describing fidelity, dose delivered, dose received, reach, and context based on Saunders et al. (2005).

   Patient Recruitment:

   - Group of interest: parents and preschoolers aged 2.5-6 years.

   - Recruitment through care providers

   - Information dissemination through flyers and personal interaction with parents. Active informed consent is required for participation, by signing a informed consent form.

   - Participants are assigned to the intervention or control group based on location. Participants recruited via schools at location X and hospital Y are assigned to the intervention group, while those recruited via schools at location A and hospital B are assigned to the control group.

   - Sample size: max. 200 parent-child dyads

   Data Collection:

   - Measurements are conducted before, after, and 3 months after the end of the sessions in both the intervention and control groups.

   - Measurements include height, weight, waist and hip circumference of the preschoolers, ActiGraph GT3X+ activity monitoring for both child and parent, a diary filled out by parents to support the activity monitor, and a questionnaire on demographic data and parent-related factors (e.g., parenting skills).

   - At the end of each session, parents in the intervention group complete a process evaluation questionnaire based on the framework of Saunders et al. (2005). The control group completes questions regarding the context at the end of the sessions, following the framework of Saunders et al. (2005), e.g., participation in health interventions.

   Intervention Session Content:

   A total of seven sessions are spread over 14 weeks, conducted in groups of 12 parent-child dyads.

   - Session 1: Parent: Information session on 24-hour behavior and parenting skills approached from the self-determination theory.

   Child: Omnisport (athletics, gymnastics, dance, and/or ball sports).

   - Session 2: Parent and child: Week scheduling.

   • Session 3:

   Parent: Discussion group on weekly planning. Child: Omnisport (athletics, gymnastics, dance, and/or ball sports). - Session 4: Parent and child: Movement games. - Session 5: Parent and child: Sleep routine. - Session 6: Parent: Discussion group on sleep routine. Child: Omnisport (athletics, gymnastics, dance, and/or ball sports).

   - Session 7: Parent: Information session on sustainable healthy behavior - persistence and dealing with relapse.

   Child: Omnisport (athletics, gymnastics, dance, and/or ball sports).

   Sessions involving parents are conducted by the leading PhD student, while omnisport for preschoolers is led by master's students from the Faculty of Medicine and Health Sciences at UGent (e.g., Rehabilitation Sciences, Exercise and Sports Sciences, Health Promotion) under her guidance.

   Data Management:

   A Data Management Plan was created using DMPonline.be.

   Data Analyses:

   R software will be used for statistical analyses. Participants need complete data for variables included in the analyses relevant to the specific research aim. Outliers with unrealistic values will be checked, and Little's test will assess whether missing data deviates from Missing Completely At Random (MCAR). Logistic regression models will be applied if necessary to explore relationships between missing values and other recorded variables. To analyze intervention effects, multilevel repeated measures will be used with three levels: time, preschooler, organization (kindergartens/hospitals), adjusted for sex, age, socio-economic status, and session group. Compositional data analyses (CoDA) will be applied to analyze the effect on 24-hour composition. Statistical significance will be set at p<0.05.
