Measuring arm circumference is a more reliable indicator of malnutrition

Research by Adam C. Levine found that arm circumference is a more accurate predictor of under-nutrition in children with diarrhea than traditional weight-based measures. This method is particularly useful in resource-limited settings where dehydration does not significantly affect the child's weight, but can impact their overall health.
