Observational Study on Childhood Obesity and Behavior

This observational study aims to understand how children's food preferences, physical activity, and decision-making change over time and how these behaviors relate to body weight. Researchers are looking for 250 children aged 8 to 11 years old who are Black, Indigenous, and People of Color (BIPOC) or Hispanic, from low-income families, and are in the overweight or obese category. The study will track changes in body mass index (zBMI), body fat, and percent change over the overweight BMI over 36 months to see how these factors develop. The current recruitment status is unclear.

Study design

What this trial measures

  • zBMI0, 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 fat0, 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 BMI0, 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.
