简要总结
The goal of this observational study is to understand how children's food preferences, physical activity, and decision-making change over time and how these behaviors relate to body weight and overall health.
详细描述
A cohort sequential design will be used to track 2 cohorts of children aged 8.5-9 years 11 months, and 10.5-11 years 11 months over a 3 year period to understand how the development of food and activity reinforcement and delay discounting could lead to the development of childhood obesity in children aged 9-14.

结局指标
主要结局
zBMI
时间窗: 0, 12, 24 and 36 months
Height and weight will be measured to determine zBMI using the CDC extended BMI-for-age growth charts. First, height (m) and weight (kg) will be used to calculate BMI (kg/m\^2), then, using the CDC extended BMI-for-age growth charts, a zBMI score will be determined based on the charts.
body fat
时间窗: 0, 12, 24 and 36 months
Body fat (% of body weight) will be measured using the Tanita BF-400 Total Body Analyzer.
percent change over the overweight BMI
时间窗: 0, 12, 24 and 36 months
Height and weight will be measured to calculate changes in overweight status of children. Change in percent overweight from 0, 12, 24, 36 months. First, height and weight will be used to calculate BMI (kg/m\^2), then CDC extended growth charts will be used to determine BMI percentile. Percent overweight is calculated as ((childBMI percentile - 85th BMI percentile)/(85th BMI percentile)) x 100. Percent over the age- and sex- specific 85th BMI percentile for children will be used.
