Studies 4
The specific objectives of the initiative are: - Conduct a set of harmonized, coordinated studies that will evaluate interventions along the life course from pre-conception to childhood to promote metabolic fitness and early development in children between 3-5 years of age; - Conduct mechanistic studies that will explain the effect of the selected interventions; - Conduct complementary policy and economic analyses; - Develop cross-country, cross-site collaborations that will provide a learning platform and training environment for young and talented scientists; - Use the generated evidence to guide policy and actions in the near future, and identify research and programmatic needs for long-term strategies.
