Computer-Aided Anthropometry in the Evaluation of Dysmorphic Children

Andreas Zankl, MD

From the Institute of Medical Genetics, University of Zurich, Zurich, Switzerland

Objective. Although anthropometry is widely regarded as the technique of choice for the evaluation of dysmorphic features among children, it is only rarely used in clinical practice. Possible reasons for this are the limited access of pediatricians to appropriate reference values and the time-consuming way measurements must be plotted onto growth charts. This article describes a computer program that overcomes these problems and greatly facilitates the use of anthropometric measurements in pediatric medicine.

Design. A computer program for PalmOS-based, handheld computers that compares entered anthropometric measurements with age- and gender-matched reference values was developed. The software is distributed free of charge and can be downloaded (www.medgen.unizh.ch/abase/).

Results. The ABase software contains age- and gender-matched reference values for 18 anthropometric measures frequently used for the evaluation of dysmorphic children. The proband's age is automatically calculated from the entered birth date and can be corrected for prematurity. Entered measurements are compared with the internal reference values; the results are displayed as percentile ranks or z scores and are plotted on digital growth charts.

Conclusions. The presented software makes anthropometric reference values easily accessible on the ward or in the clinic and greatly reduces the time needed to plot the measurements onto growth charts. This should promote more widespread use of anthropometry in pediatric medicine.
