Insights
This study tested the MEND (Mind Exercise Nutrition Do It!) program for parents of 2-4 year olds to prevent childhood obesity. Results will inform national prevention strategies.
Area of Science:
- Public Health
- Pediatrics
- Behavioral Science
Background:
- Childhood obesity is a growing concern requiring early intervention.
- The formative preschool years are critical for establishing healthy habits.
- Parental influence is significant in early childhood overweight development.
Purpose of the Study:
- To evaluate the effectiveness of the MEND (Mind Exercise Nutrition Do It!) program.
- To assess a healthy eating and childhood obesity prevention intervention for parents of 2-4 year olds.
- To provide a solution-oriented, prevention-focused approach to early childhood overweight.
Main Methods:
- Randomised controlled trial with 200 parent-child dyads.
- Ten 90-minute group workshops focusing on nutrition, physical activity, and behaviors.
- Assessment at baseline, post-intervention, and at 6 and 12 months.
Main Results:
- Data collection ongoing; results pending.
- This is the first RCT of its kind in Australia for this age group.
- Study aims to provide evidence for a scalable national program.
Conclusions:
- Parent-focused interventions are crucial for preventing preschool overweight.
- Positive trial outcomes could lead to national MEND 2-4 program implementation.
- This research addresses the need for evidence-based childhood obesity prevention.
Background:
Developing effective prevention and intervention programs for the formative preschool years is seen as an essential step in combating the obesity epidemic across the lifespan. The overall goal of the current project is to measure the effectiveness of a healthy eating and childhood obesity prevention intervention, the MEND (Mind Exercise Nutrition Do It!) program that is delivered to parents of children aged 2-4 years.
Methods/Design:
This randomised controlled trial will be conducted with 200 parents and their 2-4 year old children who attend the MEND 2-4 program in metropolitan and regional Victoria. Parent-child dyads will attend ten 90-minute group workshops. These workshops focus on general nutrition, as well as physical activity and behaviours. They are typically held at community or maternal and child health centres and run by a MEND 2-4 trained program leader. Child eating habits, physical activity levels and parental behaviours and cognitions pertaining to nutrition and physical activity will be assessed at baseline, the end of the intervention, and at 6 and 12 months post the intervention. Informed consent will be obtained from all parents, who will then be randomly allocated to the intervention or wait-list control group.
Discussion:
Our study is the first RCT of a healthy eating and childhood obesity prevention intervention targeted specifically to Australian parents and their preschool children aged 2-4 years. It responds to the call by experts in the area of childhood obesity and child health that prevention of overweight in the formative preschool years should focus on parents, given that parental beliefs, attitudes, perceptions and behaviours appear to impact significantly on the development of early overweight. This is 'solution-oriented' rather than 'problem-oriented' research, with its focus being on prevention rather than intervention. If this is a positive trial, the MEND2-4 program can be implemented as a national program.
