The USDA/ARS Children's Nutrition Research Center at Baylor College of Medicine is recruiting volunteers to participate in a two-visit study for healthy 3- to 5 -year-olds.

The purpose of the study is to develop a method to determine calories used in young children by having them wear heart rate and activity monitors. Volunteers will be asked to come in for an 8- hour session and for a brief visit after one year.

Volunteers will be compensated for their time. For more information, call Marilyn at 713-798-7002.
