Here is an official guideline from the United Nations Standing Committee on Nutrition (SCN) on the assessment of the nutritional status of adults in emergency-affected populations. This guidelines reviews the use of BMI, MUAC, clinical, and mixed indicator methods.
Here are a report and an associated presentation on the use of MUAC and W/H (using the NCHS reference and the WHO standard) for surveys estimating the prevalence of acute undernutrition and for program admission. Both were produced by Save the Children (UK) under an agreement with UNICEF on behalf of the IASC Global Nutrition Cluster.
The attached files contain David L. Pelletier's 1994 review article of the relationship between child anthropometry and mortality in developing countries.
