Based on the UNHCR SENS guidelines for refugee populations (v1.3) and the Standardized Monitoring and Assessment of Relief and Transitions (SMART) methodology (v1), a systematic sampling technique without list was used. Five camps were merged and sample was drawn from each camp based on weighted population.
From the weekly and monthly reports from the camps, the prevalence of acute malnutrition was below 10% and thus, this was regarded as expected prevalence during sample size calculation by ENA for SMART software. The desired precision was 2.5, under five children 21%, average household 4.1 and non-response rate was estimated at 10%.
According to UNHCR data the population of children aged below five year in the camp was below 10,000, therefore correction for small population of 26,800 residing in refugee camps was applied. Through ENA for SMART software, a total of 715 households had to be visited to obtain around 510 children aged 6 - 59 children for anthropometry and health assessment.
For assessment of anaemia among children aged 6 - 59 months and women aged 15 - 49 years a sub-sample was targeted consisting of all eligible children and women in every second household visited.
