Have you wondered about the difference in using Weight-for-height Z-score (WHZ) and mid-upper arm circumference (MUAC) to identify children needing nutrition treatment?
A frequent question asked of the Alliance is what appropriate anthropometric measures should be used in different contexts and how practitioners can understand the global debates and diverse evidence base relating to anthropometric criteria for identifying wasted children requiring nutrition treatment.
Our latest learning this brief describes some of the key elements and viewpoints within the debate between different anthropometric measurement approaches in order to equip practitioners with information to make decisions for their specific contexts. The brief does not intend to wade into the debate, nor comprehensively cover all of its complexities, but aims to bring clarity to what some of the key elements are within the debate around anthropometric measurements.
The key ideas and questions explored include:
- The fact that MUAC and WHZ measurements tend to identify different children
- A debate around the optimal anthropometric measure(s) for identifying the severest cases (i.e., those with the highest mortality risk) to prioritise for the most urgent treatment
- Concern that the selection of one anthropometric measure over the other may have implications for achieving greater coverage
- Concerns about admitting children for therapeutic treatment who should not be receiving it (based on admissions using different anthropometric criteria), or vice versa – not admitting children for therapeutic treatment who should be receiving treatment
