Although transgender individuals have always existed, their fight for acceptance and equal rights is just beginning. Within this larger context, one area of emerging concern is their health-physical, psychological, and social. From legislation determining public restroom access to insurance coverage of hormone therapy for transitioning individuals to harassment and discrimination, transgender people face a number of challenges that can negatively affect their well-being. A part of Greenwood's series, Part I of this book explores definitions of sex and gender, the history of transgender awareness and activism, physical and psychological health concerns specific to transgender individuals, and how identifying as transgender can have different effects on individuals' health at different stages in their life. Part II examines issues and controversies related to the health and well-being of transgender individuals. Part III provides a variety of useful materials, including case studies, a timeline of critical events, a glossary, and a directory of resources.
