To evaluate the prevalence of hepatitis B virus (HBV) infection, exposure, and immunity among Asian American college students as a basis for evaluating HBV screening and vaccination policy.
Self-identified Asian American college students aged 18 years or older were examined. Serological tests of HBV surface antigens, antibodies to HBV core antigens (anti-HBc), and antibodies to HBV surface antigens (anti-HBs) were used to determine HBV infection and immunization prevalence.
Among US-born students (n = 66), none was infected with HBV, 68% (n = 45) had immunity from vaccination, and 1 student had evidence of past exposure to HBV. Among foreign-born students (n = 142), 4% (n = 5) had evidence of chronic HBV infection, 62% (n = 88) had immunity from vaccination, and 19% (n = 27) had results indicating past exposure to HBV. Asian American college students showed very little knowledge of HBV vaccination; 43% reported that they had received vaccination, whereas 50% did not know whether they had received it or not.
The prevalence of current and past HBV infection among foreign-born Asian American college students is significantly higher (p < .01), than US-born students. The lack of awareness of their HBV-infected status points out the importance of routine HBV screening of high-risk populations such as Asian students.
评估亚裔美国大学生乙型肝炎病毒 (HBV) 感染、暴露和免疫的流行情况，为评估 HBV 筛查和疫苗接种政策提供依据。
检查了自认为是亚裔美国的 18 岁或以上的大学生。使用 HBV 表面抗原、乙型肝炎核心抗原抗体 (抗-HBc) 和 HBV 表面抗原抗体 (抗-HBs) 的血清学检测来确定 HBV 感染和免疫的流行率。
在美国出生的学生中（n = 66），没有 HBV 感染，68%（n = 45）有疫苗接种免疫，1 名学生有 HBV 既往暴露的证据。在外国出生的学生中（n = 142），4%（n = 5）有慢性 HBV 感染的证据，62%（n = 88）有疫苗接种免疫，19%（n = 27）有 HBV 既往暴露的结果。亚裔美国大学生对 HBV 疫苗接种知之甚少；43%的人报告接种过疫苗，而 50%的人不知道是否接种过。
外国出生的亚裔美国大学生目前和既往 HBV 感染的流行率显著高于（p <.01）美国出生的学生。他们对 HBV 感染状态缺乏认识，这突显了对亚裔等高危人群进行常规 HBV 筛查的重要性。
