Insights
Early obesity treatment is crucial. A parent-only program with booster sessions significantly improved weight status in preschoolers compared to standard treatment.
Area of Science:
- Pediatric Endocrinology
- Public Health Nutrition
- Behavioral Pediatrics
Background:
- Early intervention is key for effective obesity treatment in children.
- Limited effective treatment options exist for early childhood obesity.
- Parenting practices significantly influence a child's weight status.
Purpose of the Study:
- To evaluate the effectiveness of a parent-only obesity treatment program.
- To compare a parent-only program with and without booster sessions against standard treatment.
- To assess the impact on children's BMI z-score and waist circumference.
Main Methods:
- Randomized controlled trial involving 174 children aged 4-6 years with obesity.
- Three groups: parent-only with boosters, parent-only without boosters, and standard treatment.
- 12-month follow-up analyzing BMI z-score, BMI, and waist circumference using linear mixed models.
Main Results:
- Parent-only treatment led to greater BMI z-score reduction compared to standard treatment.
- The parent-only group with booster sessions showed significant improvements in weight status.
- Children in the booster group were 4.8 times more likely to achieve a clinically significant BMI z-score reduction.
Conclusions:
- A parent-only treatment program incorporating booster sessions is highly effective for preschooler obesity.
- Booster sessions enhance the long-term benefits of parent-focused obesity interventions.
- This approach offers a promising strategy for early childhood obesity management.
Background And Objectives:
Early obesity treatment seems to be the most effective, but few treatments exist. In this study, we examine the effectiveness of a parent-only treatment program with and without booster sessions (Booster or No Booster) focusing on parenting practices and standard treatment (ST).
Methods:
Families of children 4 to 6 years of age with obesity were recruited from 68 child care centers in Stockholm County and randomly assigned to a parent-only program (10 weeks) with or without boosters (9 months) or to ST. Treatment effects on primary outcomes (BMI z score) and secondary outcomes (BMI and waist circumference) during a 12-month period were examined with linear mixed models. The influence of sociodemographic factors was examined by 3-way interactions. The clinically significant change in BMI z score (-0.5) was assessed with risk ratios.
Results:
A total of 174 children (mean age: 5.3 years [SD = 0.8]; BMI z score: 3.0 [SD = 0.6], 56% girls) and their parents (60% foreign background; 39% university degree) were included in the analysis (Booster, n = 44; No Booster, n = 43; ST, n = 87). After 12 months, children in the parent-only treatment had a greater reduction in their BMI z score (0.30; 95% confidence interval [CI]: -0.45 to -0.15) compared with ST (0.07; 95% CI: -0.19 to 0.05). Comparing all 3 groups, improvements in weight status were only seen for the Booster group (-0.54; 95% CI: -0.77 to -0.30). The Booster group was 4.8 times (95% CI: 2.4 to 9.6) more likely to reach a clinically significant reduction of ≥0.5 of the BMI z score compared with ST.
Conclusion:
A parent-only treatment with boosters outperformed standard care for obesity in preschoolers.

Parenting Styles
Authoritarian Parenting
This style is strict and controlling, with little room for open dialogue. Authoritarian parents demand obedience and often enforce rules with minimal warmth. Children raised this way may lack social skills and initiative, usually comparing themselves to others unfavorably.
