Nutritional status of refugee children living in temporary settlements in Europe and MENA region: a systematic review and meta-analysis

An estimated 41% of all forcibly displaced people are children [1]. Many of these children may live in refugee camps, under poor conditions, for years. The health status of children when arriving in these camps is often not recorded, nor is there a good insight into the impact of camp life on their health. We systematically reviewed the evidence concerning the nutritional status of children living in refugee camps in the European and Middle East and North Africa (MENA) regions. We searched Pubmed, Embase, and Global Index Medicus. The primary outcome was the prevalence of stunting, and the secondary outcome was the prevalence of wasting and being overweight. Out of 1385 studies identified, 12 studies were selected, covering 7009 children from fourteen different refugee camps in the Europe and MENA region. There was great heterogeneity among the included studies, which showed that there was a pooled prevalence of stunting of 16% (95% confidence interval 9.9–23%, I(2) 95%, p < 0.01) and of wasting of 4.2% (95% CI 1.82–6.49%, I(2) 97%, p < 0.01). Anthropometric measurements were done at random points in time during the children’s camp period. However, no study had a longitudinal design, describing the effect of camp life on the nutritional status. Conclusion: This review showed that there is a relatively high prevalence of stunting and a low prevalence of wasting among refugee children. However, the nutritional status of children when entering the camp and the effect of camp life on their health is not known. This information is critical in order to inform policymakers and to create awareness concerning the health of the most vulnerable group of refugees.
