Examining the effect of three low-intensity pediatric obesity interventions: a pilot randomized controlled trial

Area of Science:

• Pediatric Health
• Obesity Treatment
• Primary Care Interventions

Background:

• Primary care settings are well-suited for addressing pediatric obesity.
• There is a need for effective, low-intensity interventions (≤25 contact hours over 6 months) to reduce standardized body mass index (z-BMI).
• Interventions should be deliverable by primary care providers.

Purpose of the Study:

• To investigate the impact of three distinct low-intensity pediatric obesity treatments on z-BMI.
• To evaluate interventions delivered within a 6-month timeframe and with limited contact hours (≤25).

Main Methods:

• A pilot randomized controlled trial involving 22 families with children (mean age 8.0 ± 1.8 years, mean z-BMI 2.34 ± 0.48).
• Participants were randomized into three 6-month conditions: newsletter only (N), newsletter plus growth monitoring (N + GM), or newsletter plus growth monitoring and family-based behavioral counseling (N + GM + BC).
• Measurements included anthropometrics, child eating behaviors, and leisure-time behaviors.

Main Results:

• A significant main effect of time was observed for both z-BMI and daily servings of sugar-sweetened beverages (P < .05).
• Both z-BMI and sugar-sweetened beverage consumption decreased over the study period.
• Improvements were noted across all intervention groups, suggesting a general positive effect of the implemented strategies.

Conclusions:

• Low-intensity obesity treatments are capable of reducing z-BMI in pediatric populations.
• These interventions demonstrate potential feasibility for implementation within primary care settings.
• Further research is warranted to optimize and scale these approaches.
