Anthropometric criteria for best-identifying children at high risk of mortality: a pooled analysis of twelve cohorts

To understand which anthropometric diagnostic criteria best discriminate higher from lower risk of death in children and explore programme implications. A multiple cohort individual data meta-analysis of mortality risk (within 6 months of measurement) by anthropometric case definitions. Sensitivity, specificity, informedness and inclusivity in predicting mortality, face validity and compatibility with current standards and practice were assessed and operational consequences were modelled. Community-based cohort studies in twelve low-income countries between 1977 and 2013 in settings where treatment of wasting was not widespread. Children aged 6 to 59 months. Of the twelve anthropometric case definitions examined, four (weight-for-age -score (WAZ)
