Rally 4A

Descriptive Epidemiology of Wasting

There currently exist good data on the prevalence of wasting in LMICs. There are minimal data on the incidence of wasting, especially age-specific incidence, severity rates, and information on the duration and recovery from wasting episodes. Knowing the incidence of wasting episodes and the conditions that precede the episode and contribute to recovery will enable focused and targeted interventions to prevent wasting.


Describe the epidemiology of incident wasting (WHZ < −2) from birth to age 24 months.


Part of the strategy for the nutrition team is to develop preventive interventions for wasting (acute malnutrition). Wasting is a major problem in LMICs, but most interventions currently are focused on treating already existing cases of wasting and not preventing new cases.


To our knowledge, this is the first systematic description of wasting incidence across a large number of contemporary cohorts. Clear differences in wasting incidence and episode duration were shown across different populations. The results from this rally provide an example of how HBGDki creates unprecedented opportunities to answer basic (and complex) epidemiologic questions across globally and historically important cohorts.
