Large Scale Interventions are implemented by political decisions;

Well informed and science based interventions have great chance of success;

Well designed and conducted evaluative studies are an important resource aiming to measure and disentangle the effect of different interventions

As child health outcomes has multiple causes and could be the effect of multiple interventions and fators, it is a necessary task to develop clear frameworks and complex study designs and analysis;

Some Remarks

While cost-effectiveness is important, the public perception of the benefits of the program is crucial;

To understand the context where the intervention occurs is an important part of the evaluative task, and to implement similar interventions in other contexts;

To have national information systems and database that collect and keep good quality routine administrative data on processes and outcomes are crucial to the large scale evaluative efforts;
