SUMMARY TABLE ON NUTRITION SURVEYS
13 December, 2000
Please find below a table summarizing information on nutrition surveys that has been made available to UNICEF Health and
Nutrition – Emergency Unit. The table indicates the methodology for survey sampling. The Health and Nutrition sub-unit is striving
towards standardization of methodology within and across districts. To this end there is a guide for training on nutrition surveys
available at UNICEF as well as a health and nutrition questionnaire which can be used by any interested agency.
Please note that this table is complied from data available currently to UNICEF - we would welcome comments and inputs from
partners in updating the information herein.

The malnutrition levels are extremely high. It is to be noted that the survey was carried out soon after a measles outbreak and there were an unusual number of
sick and malnourished children there at that point.

6 In general the malnutrition rates data from Mandera are very high. It is possible that genetically the Somali populations are leaner and thus comparing them to
the NCHS reference standards may not give the ‘true’ picture of malnutrition in these areas. There may an over-estimation of malnutrition. However, the data
from the CBS/UNICEF 5 th nutrition survey in 1994 found the GAM (
