Worldwide, men have more opportunities, privileges, and power, yet they also have shorter life expectancies than women. Why is this? Why are there stark differences in the burden of disease, quality of life, and length of life amongst men, by race, ethnicity, (dis)ability status, sexual orientation, gender identity, rurality, and national context? Why is this a largely unexplored area of research? This is the first volume to describe men's health equity as a field of study that emerged from gaps in and between research on men's health and health inequities. The handbook provides a comprehensive review of foundations of the field; summarizes the issues unique to different populations; discusses key frameworks for studying and exploring issues that cut across populations in the United States, Australia, Canada, the United Kingdom, Central America, and South America; and offers strategies for improving the health of key population groups and achieving men's health equity overall. This book systematically explores the underlying causes of these differences, describes the specific challenges faced by particular groups of men, and offers policy and programmatic strategies to improve the health and well-being of men and pursue men's health equity. It will be the first collection to present the state of the science in this field, its progress, its breadth, and its future. This book is an invaluable resource for scholars, researchers, students, and professionals interested in men's health equity, men's health, psychology of men's health, gender studies, public health, and global health.
