Awards & highlights


This trial is studying whether a multilevel intervention can reduce childhood obesity in underserved areas of Los Angeles.

Who is the study for?
This trial is for preschools in the CCRC network with at least one classroom and 20 children aged 2.5-5 who eat one meal on-site daily. Teachers must be currently teaching a class, and caregivers need to read/write English or Spanish. It excludes home-based or special needs-only preschools, and those outside the CCRC network.Check my eligibility
What is being tested?
The study tests a multilevel intervention aimed at promoting healthy eating and physical activity in underserved Los Angeles preschools. The effectiveness will be measured by changes in child BMI z-scores and parent-reported nutrition/physical activity habits.See study design
What are the potential side effects?
Since this trial involves lifestyle interventions rather than medication, traditional side effects are not applicable. However, there may be indirect impacts such as resistance to change from staff or parents which could affect the study's outcomes.

Other Research
Common treatments for obesity, particularly those similar to the multilevel preschool intervention, work by creating supportive environments that promote healthy eating and physical activity. These interventions operate on multiple levels, including organizational policies, teacher-led activities, parental involvement, and direct child engagement. Mechanisms of action include making healthier food choices the default option, increasing opportunities for physical activity, and reinforcing these behaviors at home. This comprehensive approach is crucial for obesity patients as it addresses various contributing factors, thereby enhancing the likelihood of sustainable, long-term improvements in health and behavior.
