Plain language summary
Childhood obesity is especially pronounced in those from lower socioeconomical backgrounds. The Three-Healthy Programme is a multilevel initiative designed to target obesity in these children. This randomised control trial of 104 socioeconomically vulnerable children and 59 of their parents over 12 weeks aimed to determine the effects of the Three-Healthy Programme on healthy lifestyle behaviours and obesity in children in the public welfare system. The results showed that the Three-Healthy Programme, which targeted child behavioural strategies, parenting strategies and organisational strategies helped to increase a child’s knowledge of healthy lifestyle behaviours, vegetable intake and physical activity. However, there were no improvements in breakfast, fruit, milk, no-sugar beverage and fast-food consumption. This did not translate to improved obesity status. It was concluded that the Three-Healthy Programme may be effective at promoting healthy lifestyles in socioeconomically vulnerable children. The short study duration may be the reason why obesity did not improve, at least one year of intervention may be needed. This study could be used by healthcare professionals to understand the importance of targeting all influencers for weight loss in children from socioeconomically vulnerable backgrounds.
Abstract
Background: We aimed to examine whether the Healthy Children, Healthy Families, and Healthy Communities Program, consisting of multi-level strategies for obesity prevention tailoring the context of socioeconomically vulnerable children based on an ecological perspective, would be effective on improving their healthy lifestyle behaviors and obesity status. Methods: Participants were 104 children (and 59 parents) enrolled in public welfare systems in Seoul, South Korea. Based on a cluster-randomized controlled trial (no. ISRCTN11347525), eight centers were randomly assigned to intervention (four centers, 49 children, 27 parents) versus control groups (four centers, 55 children, 32 parents). Multi-level interventions of child-, parent-, and center-level strategies were conducted for 12 weeks. Children's healthy lifestyle behaviors and obesity status were assessed as daily recommended levels and body mass index ≥85th percentile, respectively. Parents' parenting behaviors were measured by the Family Nutrition and Physical Activity scale. Results: Compared to the control group, the intervention group showed significant improvements in total composite scores of healthy-lifestyle behaviors-including 60-min of moderate physical activity-but not in obesity status among children. Moreover, the intervention group showed significant improvements in parenting behaviors among parents. Conclusion: The multi-level strategies for obesity prevention based on an ecological perspective may be effective for promoting healthy lifestyles among socioeconomically vulnerable children.
