How children's food and activity preferences and decision-making relate to weight over time

Trajectories of Reinforcement, Activity, and Consumption in Kids

Observational State University of New York at Buffalo · NCT07229508

This study will see if changes in how 9–14-year-old children value food and activity and how they make choices predict weight gain in children from low-income BIPOC and Hispanic families.

What this trial studies

A cohort-sequential observational design will follow two cohorts of children (starting ages about 8.5–9.11 and 10.5–11.11 years) for three years to cover development from roughly 9–14 years. Researchers will repeatedly measure the reinforcing value of food and activity, delay discounting (choice preferences), food liking, physical activity, and growth (height/weight/BMI). The sample focuses on children from low socioeconomic status BIPOC and Hispanic families who are in the overweight/obese range, with exclusions for medical, psychiatric, or physical conditions or medications that affect appetite or activity. No interventions are given; the aim is to map developmental behavioral trajectories that could precede or predict excess weight gain.

Who should consider this trial

Good fit: Ideal candidates are children aged about 8.5–11.11 years who are in the overweight/obese range, live primarily with a participating parent, and come from low-SES BIPOC or Hispanic families without medical or psychiatric conditions that affect weight or activity.

Not a fit: Children with medical causes of obesity, stature below the 5th percentile, major psychopathology, activity-limiting conditions, relevant medication use, or who do not spend most of their time in the participating parent's household are unlikely to receive benefit from participation.

Why it matters

Potential benefit: If successful, this work could identify early behavioral markers to target prevention and tailor interventions to reduce childhood obesity.

How similar studies have performed: Prior cross-sectional and some longitudinal research links high food reinforcement and steeper delay discounting with overeating and higher BMI, but long-term cohort data specifically in low-SES BIPOC youth are limited.
