Objective There are three major serologic markers for hepatitis B virus (HBV) infection: hepatitis B surface antigen (HBsAg); hepatitis B surface antibody (anti-HBs); and hepatitis B core antibody (anti-HBc). HBV screening programs, however, often test only HBsAg and anti-HBs, missing those individuals who have anti-HBc as the only detectable marker. Isolated anti-HBc can represent chronic infection in which HBsAg is not detectable by serology. We, therefore, investigated the prevalence of isolated anti-HBc in an ethnic community at moderate to high risk for HBV infection. Results Of 7157 Korean American adults in New Jersey, 2736 (38.2%) lacked anti-HBs, potentially susceptible to HBV. Of these 2736 subjects, 771 subjects had anti-HBc. The prevalence of isolated anti-HBc increased with age: 0.8% (age 21–30); 2.4% (age 31–40); 6.05% (age 41–50); 11.7% (age 51–60); 18.3% (age 61–70); and 24.5% (age 71–91). Similarly, the percentage of the individuals with isolated anti-HBc in anti-HBs lacking subjects showed a striking age dependence. We conclude that serologic HBV screening should include anti-HBc to accurately assess the prevalence of HBV exposure. Serologic screening with only HBsAg and anti-HBs may overestimate the prevalence of non-immune population. It can also underestimate the prevalence of HBV and increase the risk of HBV reactivation during immunosuppression.

Background Chronic hepatitis B (CHB) is a major global health issue disproportionately affecting Asian Americans and other immigrant populations in the United States. Despite the high risk of morbid complications from CHB, the majority of individuals with CHB do not access healthcare due to a complex of barriers. These barriers influence health literacy which may affect behaviors linked to hepatitis B care. We aimed to identify and evaluate various sociocultural factors and how they interact with health literacy to impact CHB care and health seeking in a Korean American population. Methods A total of 28 Korean American individuals with CHB were divided into 5 different focus discussion groups. This study investigated the participants’ sociocultural backgrounds as well as their awareness and utilization of the healthcare system that could influence their health literacy and behaviors in accessing care. Results Our analysis identified and concentrated on three themes that emerged from these discussions: low risk perception and knowledge of CHB and its complications; language, immigrant status, and stigma; and financial and institutional barriers. The participants’ overall awareness of the disease and prevention methods demonstrated poor understanding of important characteristics and potential outcomes of the disease. Additionally, differences in cultural expectations and a lack of understanding and utilization of healthcare systems affected health literacy in further limiting participants’ motivation to seek care. Conclusions The present study suggests that there are culture-specific barriers to health literacy governing individuals’ health behavior in accessing hepatitis B care. These findings may inform strategies for developing culturally tailored resources and programs and for facilitating the implementation of community-wide hepatitis B education and screening initiatives in immigrant communities.

Hepatitis B (HB) affects 240 million people around the world, and children and young adults make up a large proportion of the infected population. Approximately 1 million people die from HB each year. Despite the seriousness of HB and its complications, many are poorly linked to clinical care. A lack of health literacy may be a critical barrier hindering access to HB care for adults as well as children in these populations. We, therefore, performed a survey to assess the level of knowledge of HB among Korean American parents. The survey was conducted on 521 Korean American adults who attended community-based HB awareness campaigns held at various locations throughout the metropolitan New York area between January 2015 and November 2016. Of these, 296 parents, who had children between ages 1 and 30, were identified. All participants were asked a series of questions regarding various aspects of HB and were evaluated on the basis of their awareness on each subject. A separate questionnaire was also employed to obtain demographic characteristics of the participants. The study revealed a significant deficit of knowledge of HB in most aspects the survey evaluated. Although the majority of the participants knew that HB is a liver disease, and many of them had been screened for HB, they had a poor understanding of vaccination, screening, their own HB status, modes of HBV transmission, and the consequences and treatment of HB. The participants also had a low level of awareness of their own children’s HB status. This study demonstrates a low level of knowledge of HB among Korean American parents electing to attend a hepatitis education program. In addition, many parents are not aware of their children’s screening and immune (or non-immune) status. The lack of health literacy may contribute to poor health access in HB care, not only in adults but also in children. This suggests an urgent need for education on HB in Korean American parents as well as in young children.

BackgroundHepatitis B is an important disease of ethnic disparity which affects Asian Americans and other minority populations disproportionately. Despite the high prevalence of hepatitis B in Asian Americans, many of them remain unscreened and untreated. A majority of the individuals chronically infected with hepatitis B virus (HBV) are not linked to care, for instance, due to a lack of culturally competent programs. There are many serious barriers preventing linkage to care (LTC), including personal, socio-cultural, and economic issues. The purpose of this study was to evaluate various barriers affecting LTC and to investigate the role and efficacy of a community-based Patient Navigator (PN) program in expediting LTC and in improving health outcomes for hepatitis B patients in a high risk population.MethodsA total of 45 individuals chronically infected with HBV were identified through community screening events and were subsequently linked to patient navigators (PN), who then arranged for the patients to have a medical evaluation with a provider of their choice in their communities. The navigators kept detailed records of the patients’ progress towards goal, and planned follow up visits for each patient. A self-report questionnaire was employed to assess patients’ demographics, history of HBV infection, and barriers in accessing health care. Specifically, the levels of importance of the barriers due to language, culture, financial reasons were assessed.ResultsThe study revealed that 38 of the 45 HBV infected individuals knew about their infection status from previous screening. Forty two out of 45 HBV infected individuals were linked to care within a 12 month period, demonstrating a high linkage rate. Most significant barriers identified were language and finance, followed by cultural barrier and others.ConclusionThere are specific barriers to accessing adequate care for the patients affected by chronic hepatitis B (CHB) in Korean American community. The implementation of a PN program in conjunction with the community network of health care providers may help to overcome the barriers and facilitate LTC in hepatitis B.
