About this study

Official title: Executive Functioning, Weight Trajectories, and Loss of Control Eating in Children With Overweight/Obesity: A Prospective Study

Overweight/obesity and loss of control eating (characterized by the sense that one cannot control what or how much one is eating) are prevalent among children and adolescents, and both are associated with serious medical and psychosocial health complications. Although our recently published data suggest that youth with these conditions may have relative deficits in neurocognitive functioning, particularly working memory, understanding of how these processes and their neural correlates are related to change and stability in eating and weight-related outcomes over time is limited, thereby impeding development of targeted, optimally timed interventions. The present study aims to assess prospective associations between general and food-specific executive functioning and underlying neural substrates, and eating and weight outcomes among children at varying levels of risk overweight/obesity and eating disorders, which will help guide research efforts towards the development of effective prevention and intervention strategies.

Read the detailed description

The current study will examine prospective associations among general and food-specific EF and related neural substrates, and the developmental course of weight gain and LOC eating from middle childhood through early adolescence. Specific aims are to:

  1. Investigate prospective associations between general and food-specific EF and z-BMI trajectories. We expect that across risk groups, a) poorer baseline performance on both general and food-specific behavioral EF measures will predict steeper z-BMI gain trajectories; and b) worsening general and food-specific EF will track with the steepest z-BMI gain trajectories.
  2. Investigate associations between general and food-specific EF and LOC eating trajectories. We expect that across risk groups, a) poorer baseline performance on general and food-specific behavioral EF measures will predict worsening course of LOC eating; and b) worsening general and food-specific EF will track with worsening course of LOC eating.
  3. Investigate prospective associations between EF neural substrates and trajectories of z-BMI and LOC eating. We expect that across risk groups, a) greater activation in prefrontal regions associated with EF (e.g., dorsolateral prefrontal cortex, dorsal cingulate, parietal cortex) during general and food-specific WM tasks, and b) smaller decreases in activation of these regions over 18 months, will predict steeper z-BMI gain trajectories and worsening course of LOC eating.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. BMI (Body Mass Index)

    BMI will be assessed using height and weight (cm/g)

    Measured: Change in BMI from baseline to 24 months

  2. Eating Behavior

    Eating behavior will be assessed using the Eating Disorder Examination (EDE), a semi-structured interview. Global scores are calculated, with higher scores indicating higher disordered eating symptomology.

    Measured: Change in eating behavior from baseline to 24 months

  3. General Executive Functioning

    A general n-back task that will involve continuous presentation of neutral stimuli (letters or numbers). Participants indicate via button press whether the target (current) stimulus was presented n items ago.

    Measured: Change in general executive functioning from baseline to 24 months

  4. Food-Specific Executive Functioning

    A food-specific WM task that involves continuous presentation of stimuli representing food and non-food items. Participants indicate via button press whether the target (current) stimulus was presented n items ago.

    Measured: Change in food-specific executive functioning from baseline to 24 months

Questions about this trial

What is this clinical trial studying?

An observational study of Pediatric Obesity and Binge-Eating Disorder, run by University of Pittsburgh at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 4 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

BMI (Body Mass Index) (time frame: Change in BMI from baseline to 24 months). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Jun 2026.
