Rally 4B

Pilot of the Analysis of Risk Factors for Wasting Incidence and Recovery

In order to develop and apply interventions that prevent wasting, we need to: 1. Explore, analyze and identify risk factors for wasting incidence and recovery. 2. Identify patterns of incident wasting episodes and the conditions that precede the episode and contribute to a child’s recovery.

Focus

The focus of this raly will be to: 1. Refine the descriptive analysis report for each cohort. 2. Explore additional measures of wasting recovery, and the proportion of children wasted who recover within 30, 60, and 90 days. 3. Summarize prevalence, incidence, and duration in figures rather than tables. 4. Extend the descriptive analysis to all 22 cohorts that include a monthly measurement. 5. Begin the risk factor analyses to identify time-invariant characteristics associated with wasting episodes and recovery among children ages 0-6 months.

Background

Wasting (WHZ < −2) and severe wasting (WHZ < −3) are used to define moderate and severe acute malnutrition (MAM and SAM, respectively). Wasted children are at much higher risk of mortality. It is unknown what the long-term consequences of wasting are. There is an abundance of information about wasting prevalence in low- and middle-income countries, but almost no information about incident episodes of wasting. Of particular interest are age-specific incidence, severity, duration of wasting episodes, recovery from wasting episodes, and factors associated with incidence, severity and recovery.

value

This rally provided descriptive wasting reports for 22 cohorts which can be used as a basis for designing plans for further analyses.
