About this trial
Increased availability of high-energy dense foods has contributed to a pediatric obesity epidemic, with 23% of United States children currently presenting with the disease. How children eat contributes to both overconsumption and greater adiposity. However, it is unclear if laboratory measures of children's eating style generalize to the home environment, where children consume two thirds of their total energy. The study will 1) test if child eating styles observed in the lab generalize to more ecologically valid home environments and 2) identify aspects of home food environment that amplify obesogenic eating behaviors. We will assess laboratory and home eating styles (e.g., bite rate) in 100 prepubertal 6-9-year-old children to constrain variability in energy requirements. Children will be video-recorded while consuming identical study-provided meals at home and in the laboratory (counter-balanced order) in addition to a 'typical' meal at home. To study how adiposity relates to "obesogenic" styles of eating, gold standard dual x-ray absorptiometry will be used.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
children must be between the ages of 6-9 years-old
children are of good health with no learning disabilities (e.g., ADHD, determined by parent report)
children are not on any medications known to impact body weight, taste, food intake, behavior, or blood flow
parents report that children like and are willing to eat study foods
Disqualifiers
Children are not within the age requirements (<6 years old or > 9 years old)
If children are taking cold or allergy medication, or other medications known to influence cognitive function, taste, appetite, or blood flow.
If children don't speak English.
If children are colorblind.
Trial design
Single group
Treatments tested in this trial
Meal Location
BehavioralThe location at which the child will eat the experimental meal - home or lab
Treatment groups
Trial outcomes
Primary outcomes
Child body mass index
child height and weight will be measured
Food intake in grams during a standard meal
Intake in grams from standard meal
Food intake in kcal during a standard meal
Intake in kcal during a standard meal
Video coding of standard meal
A digital recording of the child eating a standard meal will be saved. The study team have developed a behavior coding protocol to measure child meal microstructure (e.g., bites, bite size, meal duration) and have also validated a computational model to assess cumulative intake curves from video coded bite data.
