The National Heart, Lung, and Blood Institute (NHLBI) develops health education and awareness programs to effect positive change in public health. These initiatives focus on implementing national programs to help lower the risk for and consequences of heart, lung, blood, and sleep diseases and disorders. We develop these educational programs by first synthesizing accepted scientific findings. We then use our knowledge of adult learning theory, sound behavior change, and social marketing to design informational materials that not only effectively inform our audience but also enable them to make healthy changes to their behavior. Moreover, the NHLBI partners with private-sector organizations and other Government agencies to amplify critical public health messages.
