New insights in diagnosing malnutrition in kids with cystic fibrosis

A UC Davis study explored the use of mid-upper arm circumference (MUAC) in diagnosing and classifying malnutrition in children with cystic fibrosis. The study, published in Nutrition in Clinical Practice found that MUAC and body mass index (BMI)/weight for length (WFL) z-scores were highly correlated in diagnosing malnutrition, but had poor agreement in categorizing malnutrition. MUAC z-scores identified more children in the undernourished category than BMI/WFL z-scores, with sensitivity to the mild and moderate malnourished category.
