About
The goal of this interventional study is to assess the effectiveness of the school-based "High Five!" program in reducing overweight, obesity and high blood pressure in children aged 7-9 years old. The main questions it aims to answer are:
Students participate in 6 sessions. Sessions 1-5 are dedicated to five health-related topics such as mental health, nutrition, physical activity, screen time and sleep while session 6 serves as a summarizing and reinforcing lesson. Sessions are based on active methods (play, individual / small group work) and carried out in accordance with detailed scenarios by trained specialists: the class teacher and the school nurse.
Parents/guardians of participating students are engaged in promoting healthy behaviors and creating a supportive home environment via self-reading of the "portions of knowledge" on the topics covered by the program and completion of home tasks with their children.
Full description
Background:
Excessive body weight in children is a serious and increasing health problem associated with: elevated blood pressure, risk of obesity in adulthood, poor relationships with peers, negative perception by other (as of lower intelligence, lazy etc.), susceptibility to bullying, low self-esteem and a critical attitude towards oneself.
The key risk factors of overweight in children include: low physical activity, sedentary behaviours, unbalanced diet (too much sugar-sweetened beverages and fast food), sleep disorders and mental health problems.
There are many interventions aimed at reducing overweight and obesity among children, especially those implemented in school settings. However, there is no clear evidence regarding their long-term effectiveness on obesity-related outcomes.
Objectives:
The goal of this clinical trial is to assess the effectiveness of the school-based "High Five!" program in reducing overweight, obesity and high blood pressure in children aged 6-9 years old. The main questions it aims to answer are:
Intervention:
The High Five! Program is based on the Life course theory claiming that people pass through a sequence of age-based stages and social roles within particular social structures over their lifetime that affects their health, including their body mass. The process of acquiring the skills necessary for living and acting in society to achieve life goals is extremely intensive at the beginning of school, influenced by the social environment. Children learn what behaviors are expected of them and whether they do what they do correctly. Skills acquired at this age and in this environment (classroom) help them cope with new circumstances in the future, thus becoming a lifelong asset. In this context, involving parents in the intervention via assignments, meetings, informative material and encouraging them to improve the home environment is one of the key determinants of the effectiveness of the intervention. In accordance with the family-individual-school (FIS) model of comprehensive childhood obesity prevention, "students connect the family and school, whereas parents collaborate with the school to contribute to the intervention program".
The High Five! Program is adapted to the developmental age of the 7-9 years old participants for whom, play is the favorite form of activity. Children of this age are entering a period of developing perseverance and diligence. Thay want to learn more than ever in their later lives. Therefore, it is extremely important to maintain their enthusiasm and create conditions at school that promote well-being and success. The greatest threat during this period is the child developing a belief in their own low self-worth. Children at this age enjoy listening to and telling stories, which they also use in play. They also enjoy making their own toys. They have good memory skills, especially rhymes and songs. Repetition of the same information promotes memorization. This period is also characterized by the ease of acquiring new motor skills and their improvement. This has a positive impact on daily activities, exercise, participation in sports, crafts, and playing musical instruments. And schoolteachers trained to implement health promoting interventions can have a significant impact on students' dietary behaviors.
The High Five! Program aims to prevent overweight, obesity and high blood pressure in children, by:
The High Five! Program activities include:
Students participation in 6 sessions. Sessions 1-5 (90 minutes each) are dedicated to five health-related topics:
SUPERPOWERS AND SUPER THOUGHTS- Strengthening positive self-esteem and the ability to see own strengths;
BECOME A CHEF! - Familiarizing children with the current principles of healthy eating and enhance their ability to properly compose meals;
MOVEMENT IS HEALTHY - Familiarize children with the current recommendations for physical activity and motivate them to move ;
TAKE A BREAK - Strengthening motivation and ability to control screen time;
HEALTHY SLEEP - Familiarizing children with the current recommendations for the sleep hours and how to prepare to sleep;
HIGH FIVE FOR HEALTH (45 minutes) - Summarizes and strengthens the program's message in the form of an educational board game.
Sessions are based on active methods (play, individual / small group work) and carried out in accordance with detailed scenarios by trained specialists: the class teacher and the school nurse.
Parents' engagement in promoting healthy behaviors and creating a supportive home environment via self-reading of the "portions of knowledge" on the topics covered by the program: mental health, physical activity, nutrition, sleep and screen-time and Completion of home tasks with their children (after the sessions 1-5).
Study design Researchers compare "High Five!" to the school practice as usual to see if this program works to prevent overweight and related health problems in children. The cluster randomized control trial (cRCT) design with a 1:1 ratio (experimental group vs. control group) is applied. The sampling unit is the school, and the sampling is stratified based on the size of the locality (rural/small town/large city). In each school, first- and/or second-grade classes are selected to participate. The characteristics of school environment in terms of systemic/organizational solutions at school that promote healthy eating, physical activity and a social climate friendly to students and parents will be taken into account in the outcome analysis.
Data collection is conducted in four phases: baseline (shortly before the first program session), mid-intervention (in average - after two weeks , post-intervention (shortly after the last program session), and 6-month follow-up. The evaluation includes standardized anthropometric measurements and questionnaires. Children are assessed by school nurses four times, using the Child Examination Report (height, weight, waist/hip circumference, blood pressure). Parents complete a questionnaire evaluating their child's health behaviors (e.g. diet, physical activity, screen time, sleep), emotional well-being (PSC-17), and their own health-related knowledge and supportive parenting practices 3 times (at the baseline, post-intervention and at the follow-up). Students evaluate their own health-related behaviors by marking on the picture scale, for how many days in the last 7 days, they did each of them. They answer the same question four times (at the baseline, mid-intervention, post-intervention, and 6-month follow-up). School staff (e.g., principals) will complete a questionnaire assessing the school's capacity to promote healthy behaviors. This includes food and beverage availability, opportunities for physical activity, school health policies, and implementation of health promotion initiatives.
