This concise volume guides public health advocates on how to successfully advocate for their cause, strengthen their messaging and communication strategies, build coalitions, and gather political allies. In the book, the author shares lessons learned from an exploratory study in which key legislators from the Massachusetts General Court (legislature) were interviewed to determine their level of awareness and knowledge regarding health disparities. Racial and ethnic disparities in health are a major concern for citizens, states, and the nation and are important to study and understand to strategically address and eliminate such inequities. Through these lessons, public health advocates gain an understanding of whether and how factors affect knowledge and awareness of health disparities and learn to communicate more effectively with legislators, key stakeholders, and other decision-makers. The brief also features "Notes from the Field" from those working in the "trenches" that highlight different perspectives on health disparities and provide first-hand advice for advocates hoping to close the disparities gaps and create a more equitable nation for all. Successful Public Health Advocacy is a relevant resource for advocates, as well as students, in public health, public policy, and related fields who wish to gain a better understanding on how legislators gather their health information for policy-making or constituent work and apply this data to develop and implement effective public health advocacy campaigns.
