Undernutrition among children living in refugee camps: a systematic review of prevalence.

Acute malnutrition remains a public health problem in many refugee camps, but chronic malnutrition has a high prevalence in more locations. Research and policy must, therefore, focus not only on nutrition but also on the wider determinants of both acute and chronic undernutrition. The difference in prevalence of global acute malnutrition depending on the measure used has implications for screening and diagnosis.
