Malnutrition is a health problem among children under 5 living in Internally displaced populations camps. These children are at high risk of malnutrition because of inadequate nutrition and poor care practices, which increase their vulnerability to all forms of malnutrition. The aim of this study was to determine the prevalence of different types of malnutrition in children aged 6-59 months living in Internally Displaced Populations camp in North-Kivu Province, in the east of the Democratic Republic of Congo. This is a descriptive survey of children aged 6-59 months living in Internally Displaced populations sites selected from displaced households using two-stage cluster sampling. Anthropometric measurements and the calculation of anthropometric indices for the sampled children were carried out using the World Health Organization’s 2006 growth standards. The results showed that 7.0% were emaciated, 21.4% underweight and 45.5% stunted. Children aged 24-59 months showed a high prevalence of all types of malnutrition. Males were more affected, and one of the three camps had a high prevalence of chronic malnutrition. Several of the studies cited also showed high prevalences, but this differed according to each environment. Interventions focusing on promotion, prevention and food security will need to be carried out to improve the nutritional status of internally displaced children.
