This book presents health communication scholarship from Chile, China, Colombia, Ecuador, Japan, New Zealand, Sweden, United States, and Venezuela, that recognizes the central role of communication in addressing and coping with health disparities across diverse populations. It thus advances understanding of the nuances of long standing, as well as emerging health disparities in our ever-changing social environment. The volume features eleven original, interdisciplinary research and evidence-based articles from scholars with distinct disciplinary backgrounds and unique positionalities who offer new and meaningful perspectives for scholars and practitioners in their diversity, equity, inclusion, and social justice efforts within domains such as health communication and public health. Contributions to the book facilitate meaningful dialogue and knowledge exchanges to address a wide range of key health disparities related to structural barriers and racial inequities. Featuring highly interdisciplinary research spanning from the Global South to the Global North, this book will be a key resource for researchers, scholars and practitioners in both communication studies and health sciences, as well as their respective allied fields such as media studies, telecommunications, journalism, sociology, anthropology, cultural studies, medical science, nursing, public health, psychology/psychiatry, and medical informatics. It was originally published as a special issue of Health Communication.
