History

In April 2017, the Institute partnered with the Micronutrient Forum to convene a two-day technical consultation to review seven tools designed to help decision makers in low middle income countries (LMIC) develop and streamline their nutrition programs and interventions. These tools were selected on the basis of their ability to elaborate nutrition policy scenarios adapted to national priorities and contexts, whether through the use of mathematical optimization routines or other evidence-based analytical approaches. Services provided by those tools range from advocacy to allocative efficiency to budget planning. The meeting highlighted the deep capabilities of those tools, and several examples were presented of successful use that confirmed their potential utility to nutrition policy making. Yet their adoption by end-users in LMICs remains limited. To palliate for this, the New York Academy of Sciences was awarded a 2.5 year grant by the Bill & Melinda Gates Foundation to create a consortium for nutrition modeling aimed at improving the usability of tools, and at increasing their uptake by end users.

What is Nutrition Modeling?

Nutrition Modeling refers mostly to computer assisted optimization routines that seek to select a best solution (with regard to some nutrition objective) among a set of available policy or program alternatives. However, not all tools represented on the Consortium follow mathematical optimization algorithms. Some use spreadsheet formula, while other use qualitative methods to drill down on nutrition data. Regardless of their design, they all share the intent of improving the use of available knowledge and data in designing nutrition policies and programs.

Consortium Mandate

The mandate of the Nutrition Modeling Consortium is to:

  • Increase end-users’ input in the specification of services to be provided by these tools.
  • Help end-users understand better how those tool can serve their nutrition programming needs.
  • Advance the joint utility and effectiveness of the modeling tools through a collective effort by nutrition modelers in order to enhance their technical inter-operability, and improve their usability to end-users.

How the Consortium Works

The Consortium of Nutrition Modelers aims to improve the use of the evidence base in policy and program decision making through the use of mathematical modeling of nutrition activities. It is led by a Scientific Organizing committee composed of nutrition modelers and end-users. The Secretariat has the responsibility of linking the SOC to the modeling community and to end-users, to coordinate the work of the Consortium and to organize and convene meetings of the Consortium.

Funding Support

 

Organized By

Sackler meeting

The Nutrition Modeling Consortium regroups personnel that support modeling tools, working at diverse institutions worldwide. It also includes in-country end users, such as Ministries of Health, Nutrition Departments, and implementers such as NGOs, or technical planners in-country. Membership to the Consortium is open to all stakeholders working in this area, provided they contribute to the group’s common goals.

Initiatives

Occasionally, members of the Consortium team up to jointly address special needs that are not yet covered by the group. Ongoing “work packages” are listed below:

Modeling the impact of MMS on antenatal and postnatal outcomes

Partners involved: MMS Task Force

Aim: Develop a module that allows to estimate, based on national data, the effect of switching from IFA to MMS in antenatal care programs on the following indicators: low birth weight; small for gestational age; pre-term birth; etc…)

Nutrition Theory of Change: Visualizer 

Partners involved: Led by LiST team; all consortium members participate

Aim: Provide a visualization of the various impact pathways affecting nutrition outcomes, documenting the literature, datasets, assumptions that used in the literature. This means to elaborate further the UNICEF’s Nutrition Conceptual Framework.
