Insights
Successful childhood weight management programs involve showing families practical skills, engaging the entire household, and providing social support. These interventions focus on
Area of Science:
- Pediatric Endocrinology
- Public Health Nutrition
- Behavioral Medicine
Background:
- Overweight and obesity in children (0-11 years) present significant public health challenges.
- Effective lifestyle weight management interventions require understanding key components from multiple perspectives.
- Existing research synthesis is needed to identify critical success factors for pediatric weight management.
Purpose of the Study:
- To identify critical features of successful lifestyle weight management interventions for overweight children aged 0-11 years.
- To synthesize qualitative data on children's, parents', and providers' experiences with weight management programs.
- To explore intervention evaluation data to identify mechanisms differentiating effective from least effective programs.
Main Methods:
- Qualitative synthesis of 11 UK-based studies on perspectives and experiences of weight management programs.
- Update of existing systematic reviews to identify relevant qualitative studies (search December 2015).
- Qualitative Comparative Analysis of 20 intervention evaluations (5 most effective, 15 least effective) from Western countries (search March 2016).
Main Results:
- Three critical mechanisms distinguished most effective from least effective interventions:
- 1. Demonstrating 'how to change': practical skills in physical activity, behavior change strategies, and calorie intake advice.
- 2. Engaging the 'whole family': involving both children and parents in education and behavior change efforts.
- 3. Enabling 'social support': group sessions for both children and parents fostering mutual support.
Conclusions:
- Successful childhood weight management programs require a holistic family approach.
- Interventions must actively teach practical skills and provide social support, not just directives.
- Engaging the entire family unit is crucial for program effectiveness in pediatric weight management.
Abstract:
This study aimed to identify critical features of successful lifestyle weight management interventions for overweight children (0-11years). Eleven qualitative UK-based studies examining children's, parents' and providers' perspectives and experiences of programmes were synthesised to identify components felt to be critical. Studies for this views synthesis were identified from existing reviews and an update of one review's search, which was run in December 2015. The identified components were then explored in a synthesis of intervention evaluations (five 'most effective' and 15 'least effective') conducted in western Europe, North America, Australia or New Zealand. The intervention evaluations were identified from existing reviews and an update of one review's search, which was run in March 2016. This evaluation synthesis was carried out using Qualitative Comparative Analysis. Three important mechanisms were present in all the most effective interventions but absent in all the least effective: 1/ showing families how to change: a) providing child physical activity sessions, b) delivering practical behaviour change strategy sessions, c) providing calorie intake advice; 2/ ensuring all the family are on board: a) delivering discussion/education sessions for both children and parents, b) delivering child-friendly sessions, c) aiming to change behaviours across the whole family; 3/ enabling social support for both parents and children by delivering both child group sessions and parent group sessions. To conclude, programmes should ensure the whole family is on board the programme, that parents and children can receive social support and are not just told what to change, but shown how.
