Insights
A parent mentor intervention is a feasible approach for early childhood obesity. This pilot study showed sustained reductions in adiposity for obese Hispanic children in both parent mentor and community health worker groups.
Area of Science:
- Pediatrics
- Public Health
- Behavioral Science
Background:
- Early childhood obesity is a significant public health concern.
- Effective, feasible interventions are needed to address pediatric obesity, particularly in at-risk populations.
- Positive deviance-based methods offer a novel approach to intervention design.
Purpose of the Study:
- To evaluate the feasibility of a parent mentor intervention model for early childhood obesity.
- To utilize positive deviance methods to inform intervention strategies.
- To compare the parent mentor model against a community health worker comparison group.
Main Methods:
- Pilot randomized clinical trial involving parent-child dyads (ages 2-5) with children in the ≥95th percentile for body mass index (BMI).
- Participants were randomized to either a parent mentor intervention or a community health worker comparison group.
- Feasibility assessed by recruitment, participation, and retention; primary clinical outcome was change in BMI z-score over six months and six months post-intervention.
Main Results:
- Sixty participants enrolled, with 48 completing the six-month intervention.
- No significant difference in BMI z-score change between the parent mentor and community health worker groups at the end of the intervention (-0.02; 95% CI: -0.26, 0.22).
- Both groups showed significant reductions in BMI z-score from baseline to the end of the intervention (p < 0.001), with sustained effects observed.
Conclusions:
- The parent mentor model is a feasible clinical trial approach for addressing early childhood obesity.
- Both intervention arms demonstrated small, sustained positive effects on adiposity in obese Hispanic children.
- Findings support the potential of parent-centered interventions informed by positive deviance principles.
Abstract:
Objective. To assess the feasibility of a parent mentor model of intervention for early childhood obesity using positive deviance-based methods to inform the intervention. Methods. In this pilot, randomized clinical trial, parent-child dyads (age: 2-5) with children whose body mass index (BMI) was ≥95th percentile were randomized to parent mentor intervention or community health worker comparison. The child's height and weight were measured at baseline, after the six-month intervention, and six months after the intervention. Feasibility outcomes were recruitment, participation, and retention. The primary clinical outcome was BMI z-score change. Results. Sixty participants were enrolled, and forty-eight completed the six-month intervention. At baseline, the BMI z-score in the parent mentor group was 2.63 (SD = 0.65) and in the community health worker group it was 2.61 (SD = 0.89). For change in BMI z-score over time, there was no difference by randomization group at the end of the intervention: -0.02 (95% CI: -0.26, 0.22). At the end of the intervention, the BMI z-score for the parent mentor group was 2.48 (SD = 0.58) and for the community health worker group it was 2.45 (SD = 0.91), both reduced from baseline, p < 0.001. Conclusion. The model of a parent mentor clinical trial is feasible, and both randomized groups experienced small, sustained effects on adiposity in an obese, Hispanic population.

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.
