Nutrition Interventions in the Lives Saved Tool (LiST)

Area of Science:

• Public Health
• Health Informatics
• Nutrition Science

Background:

• The Lives Saved Tool (LiST) was established in 2003 to project the effects of interventions on under-5 mortality.
• The model has evolved to incorporate additional outcomes like neonatal mortality, maternal mortality, and stillbirths.
• Risk factors such as stunting and wasting have been integrated, alongside a comprehensive array of nutrition interventions and outcomes.

Purpose of the Study:

• To review the current nutrition-related structure, assumptions, and outputs within the LiST model.
• To detail recent enhancements to LiST's nutrition modeling capabilities, focusing on new assumptions and structural additions.
• To present the complete set of nutrition-related linkages within the model and the supporting scientific literature.

Main Methods:

• Literature review of research supporting nutrition-related linkages in the LiST model.
• Analysis of the updated structure and assumptions for nutrition interventions and outcomes in LiST.
• Description of the model's expanded capacity to capture nutrition-related factors and their impact on health.

Main Results:

• LiST now includes a wider range of nutrition interventions, such as antenatal supplementation, breastfeeding promotion, and malnutrition treatment.
• The model incorporates key nutrition-related outcomes including stunting, wasting, birth outcomes, and maternal anemia.
• New assumptions and structural elements have been implemented to improve the accuracy of nutrition impact modeling.

Conclusions:

• The updated LiST model offers a more comprehensive framework for assessing the impact of nutrition interventions on maternal and child health outcomes.
• These enhancements allow for better estimation of how various nutrition strategies can reduce mortality and improve health.
• The review provides a clear overview of the model's current nutrition-related capabilities and the evidence base supporting them.
