Most public health students, academicians, and practitioners recognize the association between racial/ethnic minority status and the disproportionate burden of preventable disease in the United States. Much less attention has been directed, however, toward health disparities that affect gayand bisexual men. These disparities affect the lives of an estimated 5.3-7.4 million American men, and are an important concern for public health. Until very recently, the relative invisibility of this group and a paucity of empirical data have hampered attempts to identify health disparitiesexperienced by gay and bisexual men. This book proposes to review and synthesize evidence of health disparities among gay and bisexual men, identify individual and community factors that contribute to these disparities, and articulate strategies for public health efforts to eliminate disparities.To date, these disparities have been largely discussed in isolation in the research literature in a manner that does not permit a comprehensive examination of these problems, their underlying causes, and potential solutions. Thus, a primary emphasis of the book will be to document healthdisparities among gay and bisexual men while also describing public health solutions to these challenges.
