Outcome Measures
Primary Outcomes (1)
Internal and external satiety calories consumed
Calories consumed during ad libitum meals are measured after consumption of a high energy dense preload and a low energy dense preload and also after an external cue (smell) and a control condition.
Calories consumed are measured at week 1, week 2, week 3 and week 4.
Study Arms (1)
Siblings
Siblings will consume four test meals after 4 different exposures, including two types of koolaid, a control and a smell condition.
Interventions
Eligibility Criteria
Forty-eight sibling pairs (24 pairs of boys and 24 pairs of girls, 96 total adolescents) age 13 to 17 years who are discordant for overweight/obesity will be studied to assess potentially modifiable non-shared experiences within and outside the family environment that alter energy balance behaviors and contribute to adolescent overweight. We will also measure the height and weight of up to 3 of their best friends.
You may qualify if:
- between 13-17 years old
- Have discordant same gender sibling (one is below 70th percentile, one is above 85th percentile
- Speak/read English
- Moderate or greater liking of study foods
You may not qualify if:
- No current diagnosis of a psychiatric or eating disorder.
- No dieting, dietary restrictions, or allergies that would interfere with study participation.
- No medications or conditions that could influence taste or appetite.
- No health concern or physical disability that would limit participation in physical activity.
- No endocrine or central nervous system disorder that could produce overweight.
- No current use of tobacco or nicotine products by the adolescent siblings.
