The UNHCR Standardized Expanded Nutrition Surveys (SENS) provide regular nutrition data that plays a key role in delivering effective and timely interventions to ensure good nutritional outcomes among populations affected by forced displacement. UNHCR in collaboration with its partners, coordinated a SENS survey in Maban County between November 16th and December 4th in 2019.
Maban County is in Upper Nile State in the North East of the Republic of South Sudan (RoSS). The refugee caseload is composed of Sudanese fleeing from the conflict in Blue Nile State in Sudan, residing in four refugee camps; Doro, Yusuf Batil, Gendrassa and Kaya. The overall aim of the survey was to assess the nutrition situation among the refugee population and to monitor ongoing programme interventions. In each of the camps a cross- sectional survey was conducted using the UNHCR Standardised Expanded Nutrition Survey (SENS) version 2, 2013 guidelines http://sens.unhcr.org/ and the Standardised Monitoring and Assessments of Relief and Transitions (SMART) guidelines https://smartmethodology.org/. Systematic random sampling was used to identify the survey respondents.
Three population groups; children 6-59 months, infants 0-5 months and women of reproductive age 15-49 years were included in the survey. Household level indicators on food security were measured in households whether they included the target population groups or not.

The SENS covered the following topics:
- Children 0-23 months: feeding practices
- Children 6-59 months: prevalence of acute malnutrition, underweight, stunting and anaemia, coverage of vit A supplementation, and prevalence of diarrhoea
- Women 15-49 years: prevalence of anaemia
- Households: food security
Health and Nutrition
4 refugee camps - Doro, Yusuf Batil, Kaya and Gendrassa - in Maban County in Upper Nile State, South Sudan.
Children 0-59 months
Women 15-49 years
A household was defined as: a group of people who live together and routinely eat out of the same pot. Where two families share the same pot, they were assessed as one household even if they lived in the same compound.

Systematic random sampling was used to identify the survey respondents. Houses/tents were physically labelled with unique numbers per zone/block/compound in each camp. To reduce the non-response rate and ensure results were representative of people living in the camps at the time of the survey, empty shelters as verified through neighbours were labelled but not included in the sampling frame. The sampling interval per camp was calculated based on actual number of houses/tents that were physically verified before the survey and the sample size. Using the list generated from the physical counting and labelling of houses/tents in the camps, a sampling interval for each camp was determined by dividing the total number of verified tents/houses by the estimated sample. The first household was thereafter determined randomly using the lottery method by drawing a random number within the sampling interval. The interval was applied across the sampling frame to generate a list of households to be surveyed in the field. Each team was provided with a list of households to be surveyed daily. All the eligible household members were included in the survey; that is all children 6 to 59 months and women 15 to 49 years in a sampled household. The interview was conducted in most cases with the mother in the household or in her absence with an adult member of the household who was knowledgeable with the everyday running of the household. The survey defined a household as the number of people who regularly stay together and eat from the same pot.
In the event of an absent household or individual, the team members returned to the household during the day. If the household or individual was not found after returning, the household or individual was counted as an absentee and was not replaced. If an individual or household refused to participate, it was considered a refusal and the individual or household was not replaced with another. If a selected child was disabled with a physical deformity preventing certain anthropometric measurements, the child was still included in the assessment for the relevant indicators. If it was determined that a selected household did not have any eligible children, the relevant questionnaires were administered to the household.

Data Collection Notes
A total of six survey teams composed of four members each (one team leader, one haemoglobin measurer, one anthropometric measurer and one anthropometric/haemoglobin measurement assistant carried out data collection in Doro camp. Data collection in the rest of the three camps (Gendrassa, Kaya and Yusuf Batil) was carried out by ten teams of four members. Two standardised trainings lasting five and four days respectively were conducted for Doro and the rest of the camps. The training included a standardisation and pilot test. The survey teams were supported by a team of 5 supervisors and 2 coordinators who roved between the teams during the data collection.
Mobile phone questionnaires using Open Data Kit (ODK) android software for all the modules was used for data collection. Data validation was carried out daily by the survey coordinator/supervisors which allowed for daily feedback to the survey teams. Data analysis is currently on-going using ENA for SMART July 9th, 2015 version for anthropometric indices and Epi info version 18.104.22.168 for all other data.

1) Children 6-59 months: This included questions and measurements of children aged 6-59 months. Information was collected on anthropometric status, oedema, and enrolment in selective feeding programmes, immunisation (measles), vitamin A supplementation and morbidity from diarrhoea in past two weeks before the survey and haemoglobin status.
2) Infant 0-23 months: This included question on infant and young child feeding for children aged 0- 23 months.
3) Women 15-49 years: This included questions and measurements of women aged 15 - 49 years. Information was collected on women's pregnancy status, coverage of iron-folic acid pills and ANC attendance for pregnant women, and haemoglobin status for non-pregnant women.
4) Food Security: This included questions on access and use of the GFD ration, negative coping mechanisms used by household members and household dietary diversity.
