Through funding from a 5-year CDC Cooperative Agreement, Karna is helping the Division of Birth Defects and Infant Disorders (DBDID) develop new resources. as well as refresh, update and refine existing health communication materials. DBDID would like to better understand how pregnant people, those planning pregnancy, and new parents make risk decisions and weigh their options. Having this information will help them develop and/or update materials to help them better resonate with their intended audiences and hopefully, lead to better birth outcomes and improved maternal health. In the first year, we built an evidence base to optimize and inform communication to CDC’s intended audiences. We also used a variety of dissemination strategies, including media buys and a radio tour to reach DBDID’s audiences. In the second year, we are testing new materials and establishing a system for regular stakeholder engagement and feedback.
