Kids Obesity Prevention Program - Study (KOP). A Serious Game to Address Barriers to Prevention and Treatment of Obesity in Primary School Children

Obesity and its associated comorbidities are becoming a key and rapidly growing public health problem. The cause of obesity is an imbalance between energy intake and energy expenditure in favor of the former. Childhood and adolescence are seen as critical time for its development. It is therefore crucial to provide both prevention and treatment actions already during childhood. The prevention and treatment weight-management programs in children focus on improving diet, eating behaviours, psychosocial aspects and increasing physical activity. One important basic requirement for any weight-management program is, that both children and their families are motivated and ready for change. Video games, including exergames, serious games or combined approaches offer additional chances in the treatment and prevention of obesity by approaching children in their environment and motivating them to deal with life-style topics.

The investigators developed a motion-controlled serious game for children aged between 9 and 12 years, addressing all the three core areas nutrition, physical activity, and psychosocial factors. In addition to the motion control, a tablet is used for knowledge-based and cognitive tasks. In comparison to other studies the nutrition part not only deals with the food pyramid but also with the energy density of foods and liquids and offers a self-reflexive diagnostic tool to analyse daily food intake. Moreover, psychological aspects, especially stress and stress-coping strategies are addressed e.g. by relaxation-exercises. The game consists of two sessions, having each a duration of about 35 minutes.

The aim of this study is to evaluate the program in a cluster-randomized controlled trial in a primary school setting in children aged 9 to 12 years. Therefore, six 4th grade classes of the same school will be randomly allocated to an intervention and a control group. The intervention group will play the game within two weeks, whereas the control group will receive basic information. At baseline, two weeks after baseline and at four weeks follow-up, measurements will be performed. The primary outcome of the study is the gain of knowledge (nutrition, psychosocial aspects) measured by a self-constructed questionnaires tailored specifically for the serious game. Secondary outcomes are the acceptance of the game, changes of nutrition behaviour, physical activity and intentions of the children to follow a healthy lifestyle, measured by mostly validated questionnaires.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

9 years to 12 years (CHILD)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • all children which belong to the 4th graders of a primary school

Exclusion Criteria:

  • children with massive linguistic difficulties will be excluded (after study participation; due to ethical reasons we can not do this ahead)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: Intervention
Children in a primary school, aged between 9 and 12 years, play the serious game (two sessions, duration of each session 35 minutes, within two weeks). The game equips the children with knowledge about the core areas nutrition, physical activity, and psychosocial factors.
Other: The serious game KOP
The serious game transfers knowledge about nutrition (food pyramid, energy density of foods, which foods contribute to satiety and which not, energy in liquids, self-reflexive diagnostic tool to analyze daily food intake), physical activity (a motion-control to navigate through the game is partly used, relationship between energy expenditure and energy intake) and psychological aspects (relaxation-exercises, what is stress, stress-coping strategies).
NO_INTERVENTION: Control
Children in the same primary school, aged between 9 and 12 years do receive basic information during the study phase.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Knowledge of the children about nutrition and psychosocial aspects by a self-developed questionnaire specific for the serious game
Time Frame: Change between baseline and two weeks after the baseline measurement
Change between baseline and two weeks after the baseline measurement

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
