The purpose of this ancillary study is to examine cardiorespiratory fitness, cognitive
factors related to appetite, and objectively-measured food intake in a subsample of children
and adolescents with overweight to severe obesity enrolled in the TIGER Kids prospective
cohort. The primary study also collects data on habitual physical and sedentary activity,
body weight and body composition, and cardiometabolic health markers.
factors related to appetite, and objectively-measured food intake in a subsample of children
and adolescents with overweight to severe obesity enrolled in the TIGER Kids prospective
cohort. The primary study also collects data on habitual physical and sedentary activity,
body weight and body composition, and cardiometabolic health markers.
The investigators will enroll 30 boys and girls (50% female) between the ages of 10-16 years
and above the 85th BMI percentile (i.e., overweight to severe obesity) in this pilot
ancillary study. The objective is to examine interactions between the following
energy-balance related factors:
1. Ad libitum post-exercise food intake
2. Cognitive factors, including inhibitory control, food wanting, and motivation for food
3. Exercise-related factors, including cardiorespiratory fitness, substrate utilization
(carbohydrate versus fat), and perceived exertion
4. Habitual physical and sedentary activity
5. Body composition and cardiometabolic health
The prospective, longitudinal nature of the study will allow the investigators to examine
these variables cross-sectionally and quantify change over two years. Of particular interest
is whether cognitive factors related to energy balance, including perceived exertion,
inhibitory control, food wanting, and food motivation, vary across time or are relatively
stable. Finally, the investigators will assess the ability of these factors to predict
changes in body composition and cardiometabolic health over two years.
