The Greater Horn Region

Ethiopia

Sudanese Refugee Camps The surveys were conducted by UNHCR/WFP/ARRA in September 2001. A two stage cluster sampling methodology was used to measure children between 6-59 months. The sample sizes for the surveys were Bonga 543, Sherkole 642, Fugnido 644 and Dimma 609. For the prevalence of acute malnutrition (defined as <-2 Z scores weight for height and/or oedema) and severe acute (defined as <-3 z scores weight for height and/or oedema) see table above. Mortality rates were not measured but figures for measles vaccination coverage were and can be seen in the table above.

The prevalence of acute malnutrition (defined as <-2 Z scores weight for height and/or oedema) was estimated at 30% (95% C.I. 24.6-35.5) and severe acute (defined as <-3 z scores weight for height and/or oedema) was estimated at 2.4% (95% C. I. 1.2-3.6). Mortality rates were taken from routine surveillance and calculated over the previous 4 months to give a crude mortality rate of 0.1/10,000/day and an under five mortality of 0.27/10,000/day. Measles vaccination coverage estimated from health card was 4.5% and 83.7% from mother/carer report.
