With screening, you cant really expect a normal distribution of SAM:MAM cases, as the sampling is probably not representative, ie. children with SAM or MAM may form the greater number. The reason is that your sampling method is non-probability sampling.

I think it is difficult to generalize the proportion of SAM to MAM. I don't think there is internationally agreed cutoff point regarding proportion of MAM to SAM. for example, if there is outbreak of diseases, there could be high case of SAM. Back to your question, there could be different factors. some of these could be; 1. The screening place or site - is it community/village level screening or health facility screening or CMAM sites? 2. what is the context of the area? - is there ongoing nutrition intervention programs? sometimes some agencies implement only SFP. 3. what the public health situation? - high prevalence of morbidities such as diarrheal disease could distort the normal pattern

The ratio you give is quite unexpected. I have looked at a database of 500+ survey (SMART type) datasets and calculation the MAM:SAM ratio. There is quite a range: id muac.sev muac.mod who.sev whz.mod muac.ratio whz.ratio ---------- -------- -------- ------- ------- ---------- --------- afgh01.csv 0.90 6.90 2.60 3.85 7.67 1.48 afgh02.csv

---------- --------- Your 2:1 SAM:MAM ratio is 0.5 in the table above. There are only a handful of surveys with that ratio. I think that the reasons given by Anon730 and Kirros are correct. You are probably seeing the most wasted children coming for screening. I hope this helps.

This is very funny situation. It is the MAM cases that graduate into SAM. There is no way MAM cases can be less than the SAM cases. If the supervision was not done well, enumerators might have been measuring SAM cases only to make look like the area was not doing good nutritionally. I have done surveys for the last 7 years but I have never a case of the kind.
