Asian Americans encounter a range of health issues often unknown to the American public, policy makers, researchers and even clinicians. National research often combines Asian Americans into a single category, not taking into account the differences and complexity among Asian ethnic subgroups. The definition of Asian American derives from the U.S. Census Bureau’s definition of Asian, which includes peoples from all the vast territories of the Far East, Southeast Asia and the South Asian Subcontinent. While Census classifications determine demographic measurements that affect equal opportunity programs, the broad rubric “Asian-American” can never describe accurately the more than 50 distinct Asian American subgroups, who together comprise multifaceted diversity across cultural ethnicities, socio-economic status, languages, religions and generations. This volume rectifies that situation by exploring the unique needs and health concerns of particular subgroups within the Asian American community. It consolidates a wide range of knowledge on various health issues impacting Asian Americans while also providing a discussion into the cultural, social, and structural forces impacting morbidity, mortality and quality of life. The volume is designed to advance the understanding of Asian American health by explaining key challenges and identifying emerging trends faced in specific ethnic groups and diseases/illnesses, innovative community-based interventions and the future needed areas of research.
