Kids First Research Act of 2013

Kids First Research Act of 2013 - Amends the Internal Revenue Code to terminate: (1) the taxpayer election to designate $3 of income tax liability for financing of presidential election campaigns, (2) the Presidential Election Campaign Fund, and (3) the Presidential Primary Matching Payment Account.

Redesignates the Presidential Election Campaign Fund as the 10-Year Pediatric Research Initiative Fund. Makes amounts in the Fund available only for allocation to national research institutes and national centers through the Common Fund for making grants for pediatric research under this Act. Requires deposit into the Treasury general fund of any amounts in the Pediatric Research Initiative Fund that remain unobligated on October 1, 2024.

Amends the Public Health Service Act to require the Director of the National Institutes of Health (NIH), through the Division of Program Coordination, Planning, and Strategic Initiatives, to allocate funds appropriated under this Act to the national research institutes and national centers for making grants for pediatric research representing important areas of emerging scientific opportunities, rising public health challenges, or knowledge gaps that deserve special emphasis and would benefit from conducting or supporting additional research that involves collaboration between two or more national research institutes or national centers, or would otherwise benefit from strategic coordination and planning.

Authorizes $13 million out of the 10-Year Pediatric Research Initiative Fund for each of FY2014-FY2023 for pediatric research through the Common Fund. Requires such funds to supplement, not supplant, funds otherwise allocated by NIH for pediatric research. Prohibits the use of such amounts for any purpose other than making grants for pediatric research described in this Act.

Requires the Director of NIH, before continuing any health economics research grant, project, or activity, to report to Congress on the justification for such research, including the reason for giving it priority over research on pediatric diseases and disorders. Prohibits the Director from initiating any health economics research grant, project, or activity until the Director has submitted the report outlining the justification and a federal law has been enacted authorizing NIH to use funding specifically for health economics research.
