Abstract

The United Nations High Commissioner for Refugees (UNHCR) carried out from December 2018 to February 2019, a Standardized Expanded Nutrition Survey (SENS) in refugee camps Central Africans and Nigerians and host villages in southern Chad and the province of Lake Chad. This survey was done in collaboration with its partners, namely UNICEF, WFP, ADES and IRC. The main objective of this study was to assess the nutritional and general health status of refugees and host populations in order to formulate realistic and adequate recommendations for nutrition and public health interventions. It also aims to make a comparison of the indicators of the camps and those of their hosts.

This survey includes three modules: food & security (3233 observations), women's nutrition and health (3850 observations) and children's nutrition and health (6920 observations).

Sampling

Sampling Procedure

The type of sampling chosen for this cross-sectional survey is the two-stage cluster sampling because of the geographic and demographic size of the surveyed camps. The first step corresponds to the choice of clusters and the second to the one of households.

For the first step, the selection of the clusters was made from the figures available by zone or block using the software ENA for SMART, version 2011 (July 2015). The software has been set up so that this selection is done according to the probability proportional to size
method for each zone to ensure that each household has the same chance of being investigated within the camp, whether it is part of a large or small area.

For the second step, the households in each cluster to be surveyed will be selected by the team leaders using a systematic draw (calculation of a probing step) according to the size of each zone.

The chosen methodology is based on the UNHCR-SENS guidelines whose sampling rules are themselves derived from the SMART methodology.

Weighting

Sample weights for the household data were computed as the inverse of the probability of selection of the household, computed at the sampling domain level (camp)

Survey instrument

Questionnaires

The Child's module of the household questionnaire was administered in each household while the modules on food security and women's nutrition and health were only administered to the odd numbered housholds.

Data Editing
