The IAEA is launching a six-year Coordinated Research Project (CRP) focusing on total energy expenditure at important life stages from ages 7-13 and ages 65+, aimed at filling the knowledge gap in global understanding balance energy.

Low- and middle-income (LMIC) countries are experiencing rapidly increasing rates of overweight and obesity, as well as high levels of stunting and wasting. It is important to understand the energy balance to define appropriate implementation strategies to manage the double burden of malnutrition. The gold standard for measuring total energy expenditure in a free-living situation is the stable isotope method of doubly labeled water (DLW) technique.

In 2018, the IAEA DLW Database was launched to combine data from different DLW studies conducted around the world and enable deeper analyzes and understanding of the energy balance. Several articles have already been published from this database and it continues to change the supposed knowledge about energy balance, metabolism and body composition. However, data from PRITIs and key age groups available in the database are limited.

The information collected under the new CRP will strengthen the capacities of Member States to tackle malnutrition across the lifespan by providing new data on total energy expenditure and its determinants at important life stages.

The CRP will include at least five teams from low- and middle-income countries. Each team will bring together researchers experienced in energy balance assessment using the nuclear technique of the DLW technique.

How to join the CRP

Research organizations interested in joining the CRP must submit their Contract Proposal or Research Agreement by email, no later than September 15, 2022, to the IAEA’s Research Contract Administration Section, using the appropriate template on the ARC web portal. The same model can be used for the research contract and the technical contract. The IAEA encourages institutes to involve female and young researchers in their proposals whenever possible.

Prospective applicants should use the contact form for more information on this CRP.
