How can approaches, such as natural experiments, be used to capture the evolution and impact of policies/environmental change that are related to obesity?
There needs to be a mechanism that can quickly support the funding of natural experiment research. For instance, NIDDK and NICHD participate in a rapid response PAR that funds natural experiments in a timely manner. It only takes about 4 months from when the application is submitted to when it is a funded. NHLBI should look into the possibility of having a similar mechanism that allows for the quick review and funding of natural experiment applications.
