Description

Mwangome et al evaluated young infants for malnutrition. They identified mid-upper arm circumference (MUAC) and weight-for-age z score (WAZ) as better markers of malnutrition than weight-for-length z score (WLZ).

Patient selection: young infants in Kenya, from 1 to 6 months of age

 

Measures of malnutrition:

(1) mid-upper arm circumference < 11.0 cm

(2) weight-for-age z-score < -2

 

Outcomes:

(1) inpatient mortality

(2) post-discharge mortality up to 1 year after hospitalization

 

Areas for the ROC curves:

(1) MUAC: 0.67 to 0.70 in different clinical groups

(2) WAZ: 0.73
