Summary

The purpose of this study is to assess the validity of the PortionSize™ app to quantify children's own dietary intake and children's intake by parents or caregivers.

Detailed description

The investigators will recruit 40 dyads (40 children aged 7-12 years old and 40 parents or caregivers) using a convenience sample for this pilot study. Children and their parents or caregivers will be trained to use the PortionSize app at Pennington Biomedical Research Center (PBRC). Children will use the PortionSize app and estimate food intake from pre-weighed meals (simulated meals) at PBRC clinic. Children will not consume the simulated meals. Children's parents or caregivers will also use the PortionSize app and estimate the food intake of their children (at least one meal and a snack each day) for two consecutive days at home.
