Abstract
Young children in the Seychelles were weighed and charted using both a beam balance with the standard growth chart and using the TALC direct recording scale with integral chart. The oscillating pointer and unwanted horizontal movement of the chart in the scale resulted in unacceptable misclassification of nutritional status equivalent to a weighing error in infants of ± 2 kg. The electronic walk-on scale may provide the most important next step forward in low cost scale technology in primary health care.
