Standardized Expanded Nutrition Survey - 2012, Refugee camps: Bahn, Dougee, Solo, PTP and Little Wlebo
Refugee camps: Bahn, Dougee, Solo, PTP and Little Wlebo
Demographic and Health Survey [hh/dhs]
The UNHCR Standardized Expanded Nutrition Surveys (SENS) provide regular nutrition data that play a key role in delivering effective and timely interventions to ensure good nutritional outcomes among populations affected by forced displacement. This survey was conducted in October 2012 in Liberia in three counties (Maryland, Grand Gedeh, and Nimba) and in five refugee camp (Little Wlebo in Maryland; Solo, PTP, and Dougee in Grand Gedeh; and in Bahn camp in Nimba) hosting refugees from Côte d'Ivoire. It was organized by UNHCR and World Food Programme (WFP) in close collaboration with implementing partners, operational partners, and the Ministry of Health and Social Welfare (MoHSW) of the Republic of Liberia. This was the first of three SENS surveys that took place. Subsequent surveys took place in 2013 and 2015.

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.
Deviations from the Sample Design
During the survey, the sample size was adjusted in Little Wlebo and Bahn camps due to the fact that the non-response rate was higher than estimated.

Data Collection Notes
A three days central training of trainers (ToT) (key staff from IPs/OPs) was conducted at Zwedru in Grand Gedeh County from 4-6 October 2012 followed by rollout training to enumerators in respective camps; BO-M Nutritionist and UNHCR HQ Nutritionist facilitated the ToT. The ToT focused on various elements of the nutrition survey including the roles of supervisors and important quality related errors to be checked during the survey, in addition to sessions on how to facilitate the camp-level training. After the training the participants returned to their respective camps where they facilitated training of enumerators. All supervisors were qualified health workers. In total 12 supervisors were trained and supervised the teams during data collection.
