Community-Based Hepatitis B Campaign in Asian Americans

引用

international Journal of Clinical Medicine 2024年第9期15卷 389-412页

作者： Chul s. Hyun soonsik kim sarah Hyun Joseph McMenamin The Center for Viral Hepatitis Englewood Cliffs NJ USA Korean Community services of Metropolitan New York Bayside NY USA Mailman school of Public Health Columbia University New York NY USA Christian & Barton LLP Richmond VA USA

Chronic hepatitis B (CHB) disproportionately affects minority groups in the Us, particularly Asian Americans, with numerous factors contributing to this disparity. Of the 2.4 million people living with chronic HBV in the Us, 60% are Asian American. Many are unaware of their status and lack access to proper clinical care, with less than ten percent receiving necessary antiviral treatment. Barriers to screening and care include lack of disease awareness, language and cultural barriers, and financial constraints. Additionally, healthcare providers and systems in the Us often overlook the importance of CHB, leading to inadequate care. in response, the Center for Viral Hepatitis (CVH) has implemented a community-based outreach program over the past sixteen years, employing a multifaceted approach involving all sectors of society and various organizations to combat health dispariti.s.in CHB. This grassroots campaign has proven highly effective, leveraging CVH’s leadership in spearheading numerous collaborative activiti.s.with community members, healthcare professionals, and policymakers. We have summarized the key points of CVH's efforts and their significance in combating CHB-related health dispariti.s. The CHB screening and Awareness Campaign, tailored to the Asian American community, serves as a successful model for increasing CHB screening, linkage-to-care, and addressing socio-cultural barriers and health literacy. i.s.ghts from these outreach programs have guided the development of culturally relevant resources and education initiatives. These findings suggest that such community-driven approaches are essential for addressing health dispariti.s. The strategi.s.and outcomes of CVH’s efforts can inform future health initiatives for other minority communiti.s.in the Us and globally.
