Use of An Integrated Approach to Evaluate Young Children's Activities

Abstract:Linking a young child's activity pattern data with the environmental, biological, and personal samples that are collected during an exposure assessment is important in evaluating potential exposures and dose associated with environmental contaminants. A number of different approaches have been taken to characterize children's activity levels, including videotaping of "normal" activities of the children, completing a time activity diary or "timeline" (a simplified activity diary) by the primary caregiver, and the wearing of an accelerometer by the child.

However, there is no documented relationship between the predictability and reliability of using an accelerometer, activity time line or diary, and videotaped segments to classify activity levels of a child going about his or her daily activities. Furthermore, the use of an accelerometer to relate activity level to potential contaminant exposure and intake/uptake dose rate is novel. A pilot study was performed to collect activity data from young children (n=9, <24 months) using all three methods in an integrated manner. Because up to 4 days of information are available, intra-individual variability in the data can also be addressed. Results from this pilot study are described and the concordance among the three methods of data collecting are tested and discussed.

Although this work was reviewed by EPA and approved for publication, it may not necessarily reflect official Agency policy.
