The National Heart, Lung, and Blood Institute (NHLBI) and the National Institute on Aging (NIA) have issued a Request for Information (RFI) for High-Priority Research Topics for Sedentary Behavior (NOT-HL-13-166). Because NIH research is improved when informed by broad scientific and public input, NHLBI and NIA seek public comments about high-priority research topics that are needed to move the study of physical inactivity and sedentary behavior forward. Sedentary behavior is defined as activities that do not substantially increase energy expenditure beyond resting levels and includes activities such as sleeping, lying down, sitting, television viewing and computer use.

Information obtained will help inform the NHLBI and NIA research portfolios in this area and will help them plan for a workshop on physical inactivity. This RFI is for information and planning purposes only. NIH, NHLBI and NIA do not intend to make any awards based on responses to this RFI. All comments must be submitted electronically to through February 15, 2013.
