Jin D, Brener L, Treloar C. Knowledge and beliefs about hepatitis B virus infection and associated factors among Chinese migrants in Australia: The result of a quantitative study. HEALTH & SOCIAL CARE IN THE COMMUNITY 2022; 30:918-925. [PMID: 33237628 DOI: 10.1111/hsc.13239] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/24/2020] [Revised: 09/01/2020] [Accepted: 10/28/2020] [Indexed: 06/11/2023]
Abstract
Chinese immigrants to Australia have an increased prevalence of hepatitis B virus (HBV) infection compared to the general population. Despite this, engagement with HBV screening and healthcare for chronic hepatitis B (CHB) among immigrants of Chinese background is relatively low. This study investigated knowledge about HBV among this high-risk community and explored sociodemographic factors that might influence this knowledge. During February to September 2019, first generation Chinese immigrants from mainland China and their immediate descents residing in Sydney and Melbourne were recruited via convenience and snowball sampling and completed a survey in either English or Chinese. Survey items included HBV knowledge, attitudes towards people living with CHB and demographic information. Three hundred and ninety-six participants completed the survey. The median HBV knowledge score was 53% correct, indicating that knowledge about HBV was low to middle range among participants. While participants had the most knowledge in the domain of perceptions and understandings of HBV, this was still low. Participants also had limited knowledge about HBV prevention, transmission and treatment. Those with higher English proficiency, post-secondary education, lower levels of HBV-related stigma and those who had contact with people living with CHB appeared to have greater HBV knowledge. This study showed that HBV knowledge among Chinese people originally from mainland China living in Australia is limited and even deficient in some key areas. Additionally, the relationships between HBV knowledge and particular sociodemographic variables, knowing someone living with HBV and stigma associated with HBV provides key information to assist in the development of targeted health promotion to increase HBV knowledge and change stigmatising attitudes towards HBV among the Chinese community in Australia.

Abstract
BACKGROUND: 40% of hepatitis B carriers have no knowledge of their diagnosis. A prior study in British Columbia suggested high rates of hepatitis B among immigrants. The authors undertook a large-scale screening study to validate these rates. METHODS: Attendees at Asian health fairs without knowledge of their hepatitis B status participated. They completed a questionnaire, and blood was drawn for HBV serologies. Active HBV was defined as HBV surface antigen positive. RESULTS: Of 2,726 patients, 1,704 (62.5%) were female and 1,022 (37.5%) male. Mean age was 62.7 ± 22.1 years, and mean time of residing in Canada was 27.5 ± 15.3 years. Most patients originated from China (1,042 patients, 38.2%) and Hong Kong (871, 31.2%). 56 patients tested positive (seroprevalence rate 2.05%, 95% CI 1.52%–2.59%). Most seropositive patients were from China (28 patients, 50.0%). Mean time of residence in Canada for seropositive patients (23.8 ± 2.1 years) was less than seronegative patients (27.6 ± 0.3 years) ( p = 0.06). There was a trend towards association of seropositivity with time of residence in Canada (OR 0.98, 95% CI 0.96–1.00, p = 0.09). 8 (14.3%) seropositive patients did not have family doctors, compared with 128 (4.8%) seronegative patients. Lack of a family doctor was strongly associated with seropositivity (OR 3.31, 95% CI 1.32–7.25, χ2 = 10.42, p = 0.001). INTERPRETATION: The authors have shown that high risk immigrant populations may have seroprevalence rates as high as 2,700 per 100,000. Lack of a family physician was associated with seropositivity. These results should be used to design improved outreach programs.

ETHNICITY & HEALTH 2021; 26:1225-1241. [PMID: 31072132 DOI: 10.1080/13557858.2019.1612519] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/11/2018] [Accepted: 03/26/2019] [Indexed: 06/09/2023]
Abstract
ABSTRACTObjective: This study utilises Kleinman's theory of explanatory models of health and illness to explore the experience of chronic hepatitis B (CHB) among Vietnamese people living in Australia. It examines how these explanatory models are formed and shaped by the broader community, and the extent to which this influences understandings and responses to CHB.Design: This study is based on semi-structured interviews with 22 Vietnamese people with CHB in Melbourne, Australia. The individual interviews ranged from 30 minutes to 1.5 hours in length, and were electronically recorded, translated where necessary and transcribed verbatim. Transcripts were thematically coded using NVivo 10, with coding themes guided by categories identified in Kleinman's explanatory models framework.Results: Fundamental to most participants' narratives was the profound impact of cultural, social and economic environments on their understandings and responses to CHB. Regardless of socio-demographic background, most participants juxtaposed biomedical elements of CHB with their own existing humoral-based health belief system. In the context of a chronic asymptomatic condition that, for the most part, does not require pharmaceutical treatment, a humoral-based health belief system provided a familiar conceptual framework from which participants could immediately respond and take control of their infection. This was observed through changes in diet and lifestyle, and the use of traditional herbal medicine in an attempt to 'cure' or halt the progression of their infection.Conclusions: By speaking to people living with CHB directly, it became clear that there is a disjuncture between what is commonly assumed by the biomedical model of CHB and what is understood by individuals with the infection. The public health burden of CHB will continue unless the healthcare system, including public health policies, deliver a hepatitis B model of care that is responsive to the needs and expectations of priority populations.

Abstract
There has been a growing number of sexual health and blood-borne virus (SHBBV) surveys specifically administered to migrant populations. The purpose of this scoping review is to collate available information about how SHBBV surveys have been administered in migrant populations and the effect that mode of administration has on data quality, reliability and other practical considerations, e.g. response rates (RR) and social desirability bias. A methodological framework for scoping reviews was applied. SHBBV survey studies administered to international migrants published since 2000 were included if they contained some description of mode of administration. Ninety one studies were identified for inclusion from Embase, Medline, Web of Science, Google Scholar and supplementary grey literature. 'Interview only' was the most common mode of administration (n = 48), predominately comprising face-to-face interviews. Thirty six studies reported data from 'self-completed' surveys only, with pen-and-paper being most common (n = 17). Few studies (n = 7) combined interview and self-completed methods of survey administration. Sixty one studies did not report (or only partially reported) RR or the data necessary to calculate RR. Of the studies that reported RR, most were missing other key information including method of recruitment, consent procedures and whether incentives were offered. Strengths and limitations of all administration modes are summarised. Guidelines to inform future SHBBV survey research in migrant populations are presented.

Social Determinants of Stigma and Discrimination in Vietnamese Patients with Chronic Hepatitis B. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16030398.

Abstract
Vietnam is among the countries with the highest prevalence of chronic hepatitis B (CHB) and individuals who suffer from CHB oftentimes perceive high levels of stigma and discrimination. Our study aimed to provide evidence on the prevalence of stigma against hepatitis B virus (HBV), HBV infection, and social determinants of stigma and discrimination in patients. A cross-sectional study was conducted at Viet-Tiep Hospital, Hai Phong, Vietnam. Stigma and discrimination against CHB in the last month were measured via four dimensions: (1) Blame/Judgment; (2) Shame; (3) Discrimination in different settings; (4) Disclosure of CHB status. Multivariate Logistic and Tobit regressions were used to identify factors associated with CHB-related stigma and discrimination. Among 298 enrolled patients, 4.8% experienced blame/judgement, 10.2% perceived shame, 48.5% felt discriminated in healthcare facilities, and 90.6% disclosed their health status with spouses/partners. Factors associated with lower odds of CHB-related stigma/discrimination included living with spouses/partners, old age, being employed, and the existence of comorbidities was linked with higher odds of stigma. Anti-stigma programs should target those who are younger and have comorbidities. This could be done by community-based interventions which focus on inaccurate beliefs about viral hepatitis. Furthermore, families, healthcare providers, and society should play a crucial role in supporting CHB patients.

Abstract
INTRODUCTION Chronic hepatitis B (HBV) is prevalent among Asian immigrants in Canada with high morbidity and mortality rates. While some studies have identified barriers to health care and information access, few have studied the impact of culturally relevant information and addressed challenges with recommendations for effective public education and outreach programs. METHODS Culturally tailored HBV education workshops were delivered over a 12-month period to Chinese, Filipino, Korean and Punjabi immigrants in Lower Mainland, British Columbia (BC). Data from pre- and post-workshop surveys and 2-week and 1-month follow-up interviews were collected and analyzed to evaluate knowledge gaps and challenges around HBV prevention and screening. Barriers, health care service gaps and facilitators identified in the interviews were coded and analyzed. RESULTS Data were collected from 827 workshop participants. Our results show that targeted immigrants in Lower Mainland, BC face many barriers to accessing HBV screening and vaccination. Limited knowledge and awareness of HBV vaccination/prevention/treatment, limited English proficiency and eLiteracy skills, system and provider level barriers to accessing HBV care, and immigration related barriers are among the reported challenges. More than half of participants who took part in the HBV education workshops engaged in actions related to HBV prevention or management. CONCLUSION Study findings support the need for culturally tailored HBV public education and outreach programs to further advance HBV immunization and awareness in BC. Addressing barriers and developing targeted programmatic strategies identified in this study will promote more effective HBV education programming and improve uptake of HBV screening and vaccination in BC's immigrant populations.

Abstract
Migrant Chinese populations in Western countries have a high prevalence of chronic hepatitis B but often experience poor access to health care and late diagnosis. This systematic review aimed to identify obstacles and supports to timely and appropriate health service use among these populations. Systematic searches resulted in 48 relevant studies published between 1996 and 2015. Data extraction and synthesis were informed by models of healthcare access that highlight the interplay of patient, provider and health system factors. There was strong consistent evidence of low levels of knowledge among patients and community members; but interventions that were primarily focused on increasing knowledge had only modest positive effects on testing and/or vaccination. There was strong consistent evidence that Chinese migrants tend to misunderstand the need for health care for hepatitis B and have low satisfaction with services. Stigma was consistently associated with hepatitis B, and there was weak but consistent evidence of stigma acting as a barrier to care. However, available evidence on the effects of providing culturally appropriate services for hepatitis B on increasing uptake is limited. There was strong consistent evidence that health professionals miss opportunities for testing and vaccination. Practitioner education interventions may be important, but evidence of effectiveness is limited. A simple prompt in patient records for primary care physicians improved the uptake of testing, and a dedicated service increased targeted vaccination coverage for newborns. Further development and more rigorous evaluation of more holistic approaches that address patient, provider and system obstacles are needed.

Abstract
It is well known that community awareness of hepatitis B (HB) can lead to vaccination and testing. The study objectives were to assess the prevalence of HBV infection and knowledge of HB among adult patients attending randomly selected primary care clinics. A cross-sectional sero-survey was conducted in March 2013 in the Zgorzelec region, Poland, with the use of an investigator-developed questionnaire containing 22 questions regarding HB knowledge. Serum samples were assayed for anti-HBc total and anti-HBs with enzyme immunoassay. The prevalence of anti-HBc total among 410 participants (median age 56 years) was 10.3 % (95 % CI 7.6-13.8 %), nobody was aware of an infection. The main sources of HB knowledge were the media and medical staff. The mean knowledge score was 14.8 ± 4.9; 76.7 % of the respondents had scores >50 %. Particular gaps were detected relating to knowledge of unprotected sexual intercourse and MTCT; 45.6 % patients were not aware of the potential asymptomatic course of HBV infection, 41.2 % about chronic HB treatment. A patient's low educational level was negatively associated with a high knowledge level; the willingness for further education on HB and HBV vaccination in the past were independently associated with good knowledge. In conclusion, the HBV infection remains a public health threat in Poland, since the prevalence of infection markers in asymptomatic adult patients was high. Knowledge gaps call for awareness campaigns which may increase testing and diagnosis, audiences representing lower education level should be targeted first. Knowledge on HB might serve as an effective tool in decision making regarding vaccination.

Abstract
BACKGROUND In China, the hepatitis B virus (HBV) is a particularly challenging public health issue, with an estimated 90 million chronic hepatitis B carriers accounting for almost 7% of the population. Health-related discrimination can serve as a barrier to prevention and care for infectious diseases, such as HBV, degrade the HBV sufferers' quality of life and limit HBV patients' employment opportunities. While rural migrants account for up to 40% of the total urban population in the developed cities in China, there has been no study of the discrimination behavior of rural migrant workers toward HBV carriers. OBJECTIVE This study evaluates the discrimination behavior of rural migrant workers toward HBV carriers and patients and proposes public policy recommendations to address discrimination and stigma. METHODS The sample comprised 903 rural adults, aged over 18 years old, who migrated to Beijing. Using a face-to-face interview, we surveyed rural migrants' demographic characteristics, knowledge of HBV and discrimination against HBV carriers. Descriptive statistics were used to characterize the study population, HBV stigma and knowledge of HBV. Three discrimination levels (no-mild, medium and severe discrimination) were modeled using multiple logistic regression. RESULTS Rural migrants to Beijing had a mean age of 36 years, were overwhelmingly married (91.58%), mostly with a junior high school or lower education (78.05%) and mainly engaged as temporary workers (42.52%) or self-employed (33.78%). Only 30.56% reported that they had been vaccinated against HBV. On the 0-10 discrimination scale, rural migrants rated 6.24, with only 4.54% displaying no sign of HBV-related discrimination. The high discrimination score occurred alongside a low mean knowledge of HBV (7.61 on the 1-22 ranking of HBV knowledge). Multiple logistic regression results suggest an inverse relationship between discrimination levels and HBV knowledge, especially knowledge about treatment and transmission routes. The "fear of being infected with HBV" and being HBV vaccinated was positively associated with HBV-related discrimination. Unemployed rural migrants were more likely to exhibit severe HBV-related discrimination than other occupational groups. Personal attributes, such as gender, age, marital status and education level were not associated with the level of discrimination. CONCLUSIONS Knowledge of HBV, its transmission and treatment, and the fear of HBV infection were key features in understanding HBV discrimination by rural migrant workers. To reduce discrimination, HBV public health education campaigns need to focus on both knowledge about HBV and the fear of HBV infection. Such campaigns should target rural migrant subgroups, such as unemployed rural migrant workers.

Abstract
This comparative study explores incertitude about hepatitis B (HBV) and its implications for childhood vaccination in Bangui, Central African Republic, and the Cascades region, Burkina Faso. Anthropological approaches to vaccination, which counter stereotypes of "ignorant" publics needing education to accept vaccination, excavate alternative ways of knowing about illness and vaccination. We build on these approaches, evaluating different kinds of incertitude (ambiguity, uncertainty, ignorance) about infancy, HBV, health protection, and vaccination. Using interviews and participant observation, we find that Bangui and Cascades publics framed their incertitude differently through stories of infancy, illness, and protection. We locate different forms of incertitude within their historical contexts to illuminate why vaccination practices differ in the Cascades region and Bangui. A more nuanced approach to incomplete knowledge, situated in political, economic, and social histories of the state and vaccination, can contribute to more appropriate global health strategies to improve HBV prevention.

Abstract
Stigma regarding viral hepatitis and liver disease has psychological and social consequences including causing negative self-image, disrupting relationships, and providing a barrier to prevention, testing, and treatment. The aim of this study was to characterize and compare HBV knowledge and stigma in Vietnamese in Ho Chi Minh City and Chicago and to begin to evaluate the cultural context of HBV stigma. Methods. A written survey including knowledge questions and a validated HBV stigma questionnaire was distributed to Vietnamese in Ho Chi Minh City and Chicago. 842 surveys from Ho Chi Minh City and 170 from Chicago were analyzed. Results. Vietnamese living in Chicago had better understanding of HBV transmission and that HBV can cause chronic infection and liver cancer. Vietnamese in Chicago had higher stigma scores on a broad range of items including guilt and shame about HBV and were more likely to feel that persons with HBV can bring harm to others and should be isolated. Conclusions. Vietnamese in Ho Chi Minh City and Chicago have knowledge deficits about HBV, particularly regarding modes of transmission. Persons in Ho Chi Minh City expressed lower levels of HBV stigma than Vietnamese living in Chicago, likely reflecting changing cultural attitudes in Vietnam. Culturally appropriate educational initiatives are needed to address the problem of HBV stigma.

Abstract
Background. Our study examined hepatitis B virus (HBV) awareness and knowledge in Asian communities in British Columbia (BC). Methods. A statistical random sample representation of Chinese, Korean, Filipino, South Asian, and Southeast Asian populations in Greater Vancouver was surveyed by telephone. Multiple logistic regression analysis was performed to identify predictors of HBV knowledge. Results. General awareness of HBV was reported in 78.8% (798/1013). HBV awareness was the highest in Chinese (89%) and Filipino (88%) populations and the lowest in the South Asian (56%) population. "Reasonable" knowledge of HBV was elicited in 76.8% (778/1013). Higher HBV knowledge was associated with younger age (p = 0.014), higher education (p < 0.0001), Chinese ethnicity (p < 0.0001), and use of media (p = 0.01) and Internet (p = 0.024) for health information. Compared to the Chinese (OR = 1.0) population, "reasonable" knowledge of HBV was lower in Korean (OR = 0.3, 95% CI: 0.1-0.5), Filipino (OR = 0.3, 95% CI: 0.2-0.6), South Asian (OR = 0.3, 95% CI: 0.2-0.4), and Southeast Asian (OR = 0.3, 95% CI: 0.1-0.6) populations. 54.8% (555/1013) felt that HBV education was inadequate and 80.1% (811/1013) preferred HBV education in their native languages. Conclusion. Compared to the Chinese population, other Asian communities in BC have lower HBV awareness and knowledge. Public education should target older and less educated and Korean, Filipino, South Asian, and Southeast Asian populations in their native languages via media and Internet.

[PMID: 26475167 PMCID: PMC4609044 DOI: 10.1186/s12889-015-2388-8] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2014] [Accepted: 10/06/2015] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Hepatitis B is a significant health burden in Poland with nosocomial transmission being the main source of infection. Therefore, HBV vaccination is widely recommended for those not covered by the national immunisation program. OBJECTIVE To assess the coverage and influencing determinants of HBV vaccination among adult patients attending GP clinics as well as to establish serological status in terms of HBV infection. METHODS Patients who were seen consecutively in March 2013 at four randomly selected GP practices located in Zgorzelec county, in south-western part of Poland, were invited to participate and complete questionnaires on socio-demographic data and other factors related to vaccination. A pilot study was done in one urban GP practice in the city of Gryfino (Gryfino county), the results have been included in the study. Patients' immunisation status was assessed basing on vaccination cards and anti-HBs titer with the use of third-generation testing methods. In addition, serum samples were assayed for anti-HBc total. RESULTS Response rate: 99.3 %. Of 410 participants (66.1 % females, median age 56 years), 55.4 % (95%CI:50.5-60.1 %) were previously vaccinated; in those 11.5 % took 2 doses, 66.1 % - 3 doses,18.1 % - 4 doses. Elective surgery was the main reason (57.7 %) for HBV immunization, 4.8 % - were vaccinated due to recommendations by GPs. The multivariable logistic regression model revealed that living in a city (OR 2.11), and having a surgery in the past (OR 2.73) were each associated with greater odds of being vaccinated. Anti-HBc total prevalence among those unvaccinated was 13.6 % (95%CI:9.3 %-19,5 %), and 7.2 % (95%CI:4.4-11.8 %) among those vaccinated. CONCLUSIONS Low HBV immunization coverage among adult patients from GP clinics and the presence of serological markers of HBV infection among both - those unvaccinated and vaccinated call for comprehensive preventative measures against infection, including greater involvement of family doctors. Although interventions should cover the whole population, inhabitants living in the rural areas should be a group of special interest. Preoperative immunization for HBV seems to be an efficient public health tool to increase the vaccination uptake.

Abstract
BACKGROUND Hepatitis B virus (HBV) infection may impose an economic burden to patients or their families. The prevention and control of HBV could effectively reduce the burden. However, the management of HBV-related patients has not been well controlled in China. With the development of general practitioner (GP) system in this country, GPs may greatly improve the management of the patients with HBV infection. However, the role of GPs in controlling HBV infection has been rarely studied. DATA SOURCES A literature search of PubMed, CNKI, Wanfang data and VIP was performed with the following key words: "general practitioner", "family physician", "community management", "community health care workers", "family practice", "hepatitis B virus", "HBV", "HBV vaccination", "HBV prevention", "HBV management", "HBV treatment", "antiviral therapy" and "chronic hepatitis B (CHB)". The information about the GPs-involved prevention, diagnosis and treatment of CHB was reviewed. RESULTS The reports on the role of GPs in the prevention, diagnosis and treatment of HBV infection are few. But the experiences from Western countries demonstrated that GPs could play a significant role in the management of patients with CHB. The importance of GPs is obvious although there are some difficulties in China. GPs and health officials at different levels should work together in the management of patients with CHB. CONCLUSIONS The involvement of GPs in the management of patients with HBV infection is effective in China. But GPs' knowledge and skills for the control of HBV infection have to be improved currently. GPs' involvement will enforce the management of CHB in China in the near future.

Abstract
BACKGROUND Hepatitis B is the most prevalent chronic infectious liver disease worldwide with serious sequelae. Prevention of the infection can be provided by universal vaccination and improvement in knowledge and behavior about disease transmission. Provision of any educational program requires inquiry about target group baseline knowledge. OBJECTIVES The aim of this study was to assess Iranian adolescents' knowledge about hepatitis B (HBV) and associated factors. PATIENTS AND METHODS We conducted a questionnaire-based national survey of 18-year-old adolescents according to stratified cluster random sampling in Iran during 2007. RESULTS Response rate was 87%. Most adolescents (60%) knew that HBV infects the liver. Percentage of adolescents who gave correct answers to major routes of HBV transmission were as follows: spouse of an infected person 59%, multi-partners 66%, intravenous drug use 73%, body piercing 55% and personal belongings 55%. Higher levels of education, living in rural areas, marriage and (except for body piercing) female gender were associated with better knowledge. The knowledge of HBV infected individuals about major routes of HBV transmission was low (P < 0.001). CONCLUSIONS There are important deficits in adolescents' knowledge about HBV that requires attention of health educators to tailor educational programs for specific groups.

Abstract
BACKGROUND Immigrants have increased mortality from hepatocellular carcinoma as compared to the host populations, primarily due to undetected chronic hepatitis B virus (HBV) infection. Despite this, there are no systematic programs in most immigrant-receiving countries to screen for chronic HBV infection and immigrants are not routinely offered HBV vaccination outside of the universal childhood vaccination program. METHODS AND FINDINGS A cost-effective analysis was performed to compare four HBV screening and vaccination strategies with no intervention in a hypothetical cohort of newly-arriving adult Canadian immigrants. The strategies considered were a) universal vaccination, b) screening for prior immunity and vaccination, c) chronic HBV screening and treatment, and d) combined screening for chronic HBV and prior immunity, treatment and vaccination. The analysis was performed from a societal perspective, using a Markov model. Seroprevalence estimates, annual transition probabilities, health-care costs (in Canadian dollars), and utilities were obtained from the published literature. Acute HBV infection, mortality from chronic HBV, quality-adjusted life years (QALYs), and costs were modeled over the lifetime of the cohort of immigrants. Costs and QALYs were discounted at a rate of 3% per year. Screening for chronic HBV infection, and offering treatment if indicated, was found to be the most cost-effective intervention and was estimated to cost $40,880 per additional QALY gained, relative to no intervention. This strategy was most cost-effective for immigrants < 55 years of age and would cost < $50,000 per additional QALY gained for immigrants from areas where HBV seroprevalence is ≥ 3%. Strategies that included HBV vaccination were either prohibitively expensive or dominated by the chronic HBV screening strategy. CONCLUSIONS Screening for chronic HBV infection from regions where most Canadian immigrants originate, except for Latin America and the Middle East, was found to be reasonably cost-effective and has the potential to reduce HBV-associated morbidity and mortality.

Abstract
BACKGROUND AND AIM While hepatitis B virus (HBV) prevalence is known to vary greatly between countries, systematically collected population-level prevalence data from some countries is limited. Antenatal HBV screening programs in countries with substantial migrant populations provide the opportunity to systematically examine HBV prevalence in order to inform local and regional HBV estimates. METHODS A comprehensive register of Australian mothers giving birth from January 2000 to December 2008 was linked to a register of HBV notifications. Age-standardized prevalence of chronic HBV were calculated overall and by the mother's country of birth. Multiple logistic regression was used to investigate other factors associated with HBV prevalence. RESULTS Five hundred twenty-three thousand six hundred sixty-five women were included and linked to 3861 HBV notifications. The age-standardized HBV prevalence was low (0.75%, 95% confidence interval 0.72-0.79). The highest HBV prevalence rates were observed in women born in Cambodia (8.60%), Taiwan (8.10%), Vietnam (7.49%), China (6.80%), and Tonga (6.51%). Among Australia-born women, those who smoked during pregnancy, were from a more disadvantaged socioeconomic background, and lived in remote areas were more likely to have HBV. There was also a trend suggesting a decrease in the prevalence of HBV over time. CONCLUSIONS Antenatal screening for HBV can provide systematic population estimates of HBV prevalence in migrants and also identify other high prevalence groups. Longer follow-up will be required to confirm the small decrease in HBV prevalence observed in this study.

Abstract
BACKGROUND This study aimed to investigate the level of awareness of and factors associated with major infectious diseases in rural China and to provide the most recent baseline data for the prevention and control of these diseases. METHODS This cross-sectional study was carried out in Zhejiang province between December 2010 and April 2011. Participants were recruited from 36 villages and interviewed by doctors from the community health service using a structured questionnaire. RESULTS The study sample consisted of 36,377 subjects aged 15 to 80 years old. Study results showed that knowledge of HIV was adequate in 44.21% of rural residents; knowledge of TB was adequate in 52.66% of respondents; and knowledge of HBV was adequate in 60.18% of respondents. People in older age groups and with lower education levels were more likely to have low levels of awareness of these three infectious diseases. Participants in the farming industry had poorer awareness of HIV and HBV, while students and factory workers knew little of TB. The proportions of people reporting being fully satisfied with the control policies for HIV, TB and HBV were 37.70%, 34.25% and 36.12%, respectively. CONCLUSIONS The level of awareness of HIV, TB and HBV is still low among rural residents. Further national disease control plans for major infectious diseases should emphasise effective and comprehensive health education campaigns to increase public awareness of these diseases in rural areas of China.

Abstract
We explored attitudes about prevention, screening and treatment of hepatitis B virus (HBV) infection in Chinese, Korean and Vietnamese communities. We use qualitative methods in 12 focus groups (n = 113) of adults who self-reported their ethnicity to be Chinese, Korean, or Vietnamese. We use grounded theory (i.e., consensus-building between co-coders about recurring, emerging themes) for analysis. Diet, nutrition, fatigue and stress were misidentified as HBV causes. Improving hygiene, diet, exercise, and holistic methods were misidentified as viable HBV prevention methods. Common screening problems included not affording test and not understanding test results. Participants shared reasons for using complementary and alternative medicine--when Western medicine fails or becomes unaffordable. Participants sought information from medical providers and fellow community members, but also from the internet. Many of the attitudes and opinions that emerged may deter participation in HBV screening, prevention and treatment, insofar as community members may factor them into healthcare decision-making, choose alternative but ineffective methods of prevention and treatment, and undervalue the benefits of screening. More patient education in both traditional and new media is necessary for clarifying transmission, screening and treatment misunderstandings.

Abstract
Background Although the risk of hepatitis B virus (HBV) was reported to be higher in military personnel than the general population in Saudi Arabia (SA), there is lack of studies assessing HBV awareness among them. The objective was to evaluate the knowledge, attitude and practice (KAP) of HBV infection among military personnel. Methods An intervention design with pre- and post-education KAP questionnaire was completed among National Guard soldiers working in Jeddah during January 2009. Educational intervention was provided through educational leaflets, group and individual discussions, visual show, and a lecture. A score was created from the correct answers to 58 questions. Results A total of 400 male soldiers with mean age 30.7 ± 6.1 years completed both questionnaires. The majority had school education (96.8%) and in the lower military ranks (66.0%). Only 19.5% of soldiers reported HBV vaccine intake. The low median and inter-quartile range of the pre-intervention score (16, 6–26) markedly increased after education (to 53, 50–55, p<0.001). The overall improvement of mean KAP score (204%) was also observed in all its component scores; disease nature (272%), methods of transmission (206%), prevention and control (109%), attitude (155%), and practice (192%). The improvement was evident irrespective of socio-demographic characteristics and history of HBV vaccine. KAP scores were significantly associated with higher educational levels, higher monthly income, administrative jobs, and higher job ranks. Conclusion We are reporting a low level of HBV awareness among Saudi military population. The study confirms the need and effectiveness of focused multifaceted educational campaigns among the military population.

Abstract
Hepatitis B infection is a major global health problem. Vertical transmission is the commonest route of spreading hepatitis B virus (HBV) in many endemic areas. In order to control such transmission in Hong Kong, neonatal immunization programme was implemented for more than two decades. A declining prevalence of HBV infection was expected. However, the prevalence remained unabated at around 10% in recent studies. We suspect that one of the explanations of this persistent high prevalence is deficient knowledge on infection with the HBV and its prevention. Our paper gives an overview of the knowledge on HBV infection among Chinese population in both high and low endemic areas and discusses the potential factors that influenced the knowledge on as well as the implication of the sources of information for HBV infection, which was not addressed in previous studies.

Abstract
Asians are disproportionately affected by chronic hepatitis B (HBV) infection and its fatal consequences. The Hep B Free campaign was launched to eliminate HBV in San Francisco by increasing awareness, testing, vaccination and linkage to care. The campaign conducted 306 street intercept and telephone interviews of San Francisco Asians to assess current levels of HBV knowledge, testing behaviors and effectiveness of existing campaign media materials. One-third of respondents ranked HBV as a key health issue in the Asian community, second to diabetes. General HBV awareness is high (85%); however, a majority could not name an effective prevention method. Sixty percent reported having been tested for HBV; provider recommendation was the most often cited reason for testing. Respondents reported a high level of trust in their providers to correctly assess which health issues they may be at risk for developing and test accordingly, confirming that efforts to increase HBV testing among Asians must simultaneously mobilize the public to request testing and compel providers to test high-risk patients. Regarding community awareness, more than half reported hearing more about HBV recently; younger respondents were more likely to have encountered campaign materials and recall correct HBV facts. Assessment of specific campaign materials found that while upbeat images and taglines captured attention and destigmatized HBV, messages that emphasize the pervasiveness and deadly consequence of infection were more likely to drive respondents to seek education and testing. The campaign used survey results to focus efforts on more intensive provider outreach and to create messages for a new public outreach media campaign.

Abstract
Health-related stigma is a cause of stress, alienation and discrimination that can serve as a barrier to prevention and care for infectious diseases such as HIV. Hepatitis B virus (HBV)-related stigma is common in Asian immigrants, but has not been formally evaluated. The aim of this study was to develop and validate the first HBV stigma instrument and to begin to evaluate HBV stigma in Chinese immigrants. The HBV stigma instrument was developed based on constructs from validated HIV stigma scales and organized into five domains. A written survey was compiled to include demographic data, HBV knowledge questions and stigma items. The survey was pilot tested in English and Chinese and then finalized. Data were obtained from 201 patients seen in an urban Chinatown Internal Medicine practice. The stigma items showed a high degree of reliability when assessed in aggregate (α = 0.85) as well as within individual domains. Stigma was greatest in the Fear of Contagion domain. Knowledge questions showed a corresponding deficit in understanding of modes of HBV transmission. An inverse relationship between stigma scores and familiarity with HBV provided evidence of construct validity. In multivariable analysis, having a family member with HBV and higher HBV knowledge subset scores were associated with lower degrees of stigma. In conclusion, the hepatitis B stigma instrument showed reliability and construct validity. The relationship identified between familiarity and knowledge regarding HBV with lower stigma scores provides the basis for the development of interventions to reduce HBV stigma.

Abstract
OBJECTIVE To assess the knowledge on hepatitis B virus (HBV) infection and associated factors among expectant mothers in an endemic region. METHODS A questionnaire was administered to pregnant Chinese women (n=1623) attending the antenatal clinic to examine their knowledge on HBV infection, and correlating this with socio-demographic, medical and obstetric factors. RESULTS Independent factors associated with insufficient reduced HBV knowledge include women outside the healthcare sector, lower education level, and no previous HBV testing. The majority of respondents could provide correct responses about the common aspects of HBV infection, including screening, blood-borne and perinatal transmissions, prevention by vaccination, and sequelae of HBV infection, but 47.1% did not know that HBV is transmissible by sexual intercourse. Over 75% respondents misunderstood the fact that HBV cannot be transmitted through food, or prevented by a balanced life style and nutrition. CONCLUSIONS Misconceptions about HBV transmission are still common among the obstetric population, and the provision of appropriate and correct information is warranted to improve further the control of HBV infection to the target group. PRACTICE IMPLICATIONS Appropriate emphasis should be given to educating the general population about horizontal transmission of HBV.

Abstract
Although primary prevention of HAV and HBV can be achieved through vaccination, the burden of HCV can only be reduced through behavioral interventions to reduce its risk factors. This study evaluated knowledge regarding transmission, clinical manifestations and prevention of viral hepatitis in Puerto Rico. We assessed the level of knowledge about HAV (six questions), HBV (12 questions) and HCV (eight questions) among non-institutionalized Puerto Rican adults aged 21-64 years. Demographic characteristics and self-reported knowledge of these infections were determined through a face-to-face interview. A mean knowledge score was computed by summing correct responses to each scale. Mean knowledge scores according to demographics were compared using ANOVA or the Kruskal-Wallis test. Mean knowledge scores for HAV, HBV and HCV infections were 2.6 ± 1.5, 6.1 ± 2.4, and 3.6 ± 1.1, respectively. For HAV and HBV infections, the mean knowledge score significantly (P < 0.05) increased with age, level of counseling received and number of sources of information. However, for HCV infection the mean knowledge score significantly increased with decreasing age, increased educational level and increased annual family income. Contrary to HBV, a higher HAV and HCV knowledge score was observed among individuals with history of vaccination for HAV and HBV, seropositive status for HAV and HCV, and history of drug use. A sizeable proportion of adults in this study demonstrated an inadequate level of knowledge, especially about transmission routes. Health education must be focused on transmission and prevention methods, including the availability of a vaccine for HAV and HBV, especially among those with chronic liver disease.

Abstract
Hepatitis B virus infections are an important health problem in the Turkish community in the Netherlands. Screening for hepatitis B should be promoted through public health interventions, which take into account the socio-cultural and behavioural determinants that influence screening. The Intervention Mapping protocol was used to develop a culturally tailored Internet intervention for first-generation Turkish immigrants in Rotterdam, aged 16-40 year. Behavioural factors and cultural motivators and barriers, identified in the first steps of the protocol, were incorporated in the intervention. To ensure participation, members of the target population were involved in all steps of programme development. A theory- and evidence-based culturally tailored intervention was developed. Both surface structure and deep structure elements were used; surface structure tailoring resulting in different Internet skins and peer-stories for subgroups, such as young women. Deep structure elements comprised cultural motivators such as the religiously inspired feelings of responsibility and strong family values, and perceived community rules regarding health and disease. Cultural barriers that were addressed were the satisfaction and trust in Dutch health care, and the association of hepatitis B screening with sexual behaviour. Intervention Mapping provided a useful framework for the systematic development of our theory- and evidence-based intervention to promote hepatitis B screening in the Turkish community in the Netherlands.

Abstract
Canadian immigrants have lower overall cancer risk than the Canadian-born population. Less is known about risks for immigrant subgroups and site-specific cancers. Linked administrative data sets were used to compare cancer incidence between subgroups of immigrants to Canada and the general Canadian population. The study involved 128,962 refugees and 241,010 non-refugees. Standardized incidence ratios (SIRs) were calculated for all-site and site-specific cancers by immigration categories and regions of birth. Relative to the general Canadian population, incidence of all-site cancer was lower among immigrants overall, by sex and refugee status (non-refugee SIRs 0.25: men, 0.24: women; refugee SIRs 0.31: both). Significantly higher SIRs resulted for liver, nasopharyngeal and cervical cancers, including liver cancer among South-East Asian and North-East Asian immigrants, and nasopharyngeal cancer among North-East Asian non-refugees. Hypothesized explanations for variation in cancer incidence include earlier viral infection in the country of origin.

Abstract
Surname lists are increasingly being used to identify Asian study participants. Two Vietnamese surname lists have previously been published: the Vietnamese Community Health Promotion Program (VCHPP) list and the Lauderdale list. This report provides findings from a descriptive analysis of the performance of these lists in identifying Vietnamese. To identify participants for a survey of Vietnamese women, a surname list (that included names that appear on the VCHPP list and/or Lauderdale list) was applied to the Seattle telephone book. We analyzed surname data for all addresses in the survey sample, as well as survey respondents. The VCHPP list identified 4,283 potentially Vietnamese households, and 79% of the households with established ethnicity were Vietnamese; and the Lauderdale list identified 4,068 potentially Vietnamese households, and 80% of the households with established ethnicity were Vietnamese. However, the proportions of contacted households that were Vietnamese varied significantly among commonly occurring surnames. The characteristics of women with surnames on the VCHPP and Lauderdale lists were equivalent. The two lists performed equally well in identifying Vietnamese households. Researchers might consider using different combinations of Vietnamese surnames, depending on whether accuracy or high population coverage is the more important consideration.

Abstract
Asian communities in North America include large numbers of immigrants with limited English proficiency. Hepatitis B virus (HBV) infection is endemic in most Asian countries and, therefore, Asian immigrant groups have high rates of chronic HBV infection. We conducted a group-randomized trial to evaluate the effectiveness of a hepatitis B English as a second language (ESL) educational curriculum for Asian immigrants. Eighty ESL classes were randomized to experimental (hepatitis B education) or control (physical activity education) status. Students who reported they had not received a HBV test (at baseline) completed a follow-up survey 6 months after randomization. The follow-up survey assessed recent HBV testing and HBV-related knowledge. Provider reports were used to verify self-reported HBV tests. The study group included 218 students who reported they had not been tested for HBV. Follow-up surveys were completed by 180 (83%) of these students. Provider records verified HBV testing for 6% of the experimental group students and 0% of the control group students (P = 0.02). Experimental group students were significantly (P < 0.05) more likely than control group students to know that immigrants have high HBV infection rates, HBV can be spread during sexual intercourse and by sharing razors, and HBV infection can cause liver cancer. Our ESL curriculum had a meaningful impact on HBV-related knowledge and a limited impact on HBV testing levels. Future research should evaluate the effectiveness of ESL curricula for other immigrant groups and other health topics, as well as other intervention approaches to increasing levels of HBV testing in Asian immigrant communities.

Abstract
Hepatitis B is a significant public health challenge within some subpopulations in Australia, including Chinese and Vietnamese migrants. There has been limited research on hepatitis B knowledge and actions in these communities. The authors conducted a self-administered survey among 442 Chinese and 433 Vietnamese in Brisbane. Generally, the knowledge is best described as “moderate.” One in 2 could not identify the sexual transmission risk and less than one third knew that sharing foods or drinks did not spread the disease. The majority of Vietnamese (80%) and 60% of Chinese respondents indicated prior testing. Vaccination was reported in 60% of the Vietnamese and in 52% of the Chinese. Knowledge was better among Chinese people who had been tested and vaccinated compared with those who were nontested and nonvaccinated. Only 3.5% of the Chinese, but 11.6% of the Vietnamese, indicated having a positive test result hepatitis B virus. This study helps identify strategies for programs targeting both communities and practitioners.

Abstract
OBJECTIVE To conduct a systematic review examining whether minority ethnic populations participate in surveys as actively as the majority ethnic population. METHODS A literature and grey literature search was conducted using five online databases as well as government databases and reports, including the search terms: survey response rates or non-response rates and racial or ethnic populations (White, African American, Asian, and Hispanic); survey modes or methods (mail, telephone, face to face, e-mail); and response bias (non-response bias, response bias or social desirability). The search was limited to English language and articles published from January 1990 to June 2009. Article exclusions were based on further inclusion and exclusion criteria. SYNTHESIS Thirty-five articles were identified on ethnicities and response rates to survey modes. Six articles compared survey mode and response rate for multiple ethnic populations. Response rates ranged from 22.0% to 68.8% in Whites, and in other ethnic groups ranged from 15.4% in African Americans to 70.9% in Latino Americans. Among the 29 articles that presented survey mode and response rate for a specific ethnicity, the highest response rate reported was from African Americans (92.5%) and the lowest was from Cambodian Americans (30.3%). CONCLUSION Response rate varied across studies but was similar across ethnicities. Response rate may be related to many factors, including survey mode, length of questionnaire, survey language and cultural sensitivity to content. Our review indicates that ethnic populations who participate in surveys are as likely to participate in research as Whites. In literature, data validity across ethnicity is still unknown and should be studied in the future.

Abstract
Background Hepatitis B virus infection is an important health problem in the Turkish community in the Netherlands. To prevent transmission and progression of the disease in this community, increased screening is necessary. This study aimed to determine 1) the levels of awareness and knowledge regarding hepatitis B, comparing these in tested and non-tested Turkish-Dutch in Rotterdam; 2) the self-reported hepatitis B test status in this population, and how this is related to demographic characteristics, knowledge and awareness. Methods We conducted a postal survey amongst first and second generation migrants, aged 16 - 40 years. Results The response rate was 30.2% (n = 355 respondents). Levels of awareness and knowledge regarding hepatitis B were low, as the majority of respondents (73%) never thought about the disease and 58% of the respondents scored 5 or less out of ten knowledge items. Weighted analysis of self-reports showed a test rate of 15%, and a vaccination rate of 3%. Regression analysis showed that having been tested for hepatitis B was related to being married and higher levels of awareness and knowledge. Conclusions This study shows low levels of hepatitis B awareness and knowledge in the Turkish community in Rotterdam. Self-reported test rates are lower in people who are not currently married, and in those who have low levels of awareness and knowledge. Especially, knowledge about the consequences of hepatitis B, such as liver cancer, was lacking. Therefore, a health promotion intervention should foremost raise awareness, and increase knowledge on the seriousness of this disease.

Abstract
Background Hepatitis B is an important health problem in the Turkish community in the Netherlands. Increased voluntary screening is necessary in this community, to detect individuals eligible for treatment and to prevent further transmission of the disease. Methods We investigated socio-cultural determinants associated with hepatitis B screening in male and female, first and second generation Turkish migrants, by means of Focus Group Discussions. Results Socio-cultural themes related to hepatitis B screening were identified; these were social norm, social support, sensitivity regarding sexuality, reputation, responsiveness to authority, religious responsibility, cleanliness and religious doctrine regarding health and disease, and the perceived efficacy of Dutch health care services. Motivating factors were the (religious) responsibility for one's health, the perceived obligation when being invited for screening, and social support to get tested for hepatitis B. Perceived barriers were the association of hepatitis B screening with STDs or sexual activity, the perception of low control over one's health, and the perceived low efficacy of the Dutch health care services. Reputation could act as either a motivator or barrier. Conclusion This study identified relevant socio-cultural themes related to hepatitis B screening, which may serve to customize interventions aimed at the promotion of voluntary hepatitis B screening in the Turkish-Dutch population in the Netherlands.

Abstract
BACKGROUND The Western Pacific region has the highest level of endemic hepatitis B virus (HBV) infection in the world, with the Chinese representing nearly one-third of infected persons globally. HBV carriers are potentially infectious to others and have an increased risk of chronic active hepatitis, cirrhosis, and hepatocellular carcinoma. Studies from the U.S. and Canada demonstrate that immigrants, particularly from Asia, are disproportionately affected by liver cancer. PURPOSE Given the different health care systems in Seattle and Vancouver, two geographically proximate cities, we examined HBV testing levels and factors associated with testing among Chinese residents of these cities. METHODS We surveyed Chinese living in areas of Seattle and Vancouver with relatively high proportions of Chinese residents. In-person interviews were conducted in Cantonese, Mandarin, or English. Our bivariate analyses consisted of the chi-square test, with Fisher's Exact test as necessary. We then performed unconditional logistic regression, first examining only the city effect as the sole explanatory variable of the model, then assessing the adjusted city effect in a final main-effects model that was constructed through backward selection to select statistically significant variables at alpha=0.05. RESULTS Survey cooperation rates for Seattle and Vancouver were 58% and 59%, respectively. In Seattle, 48% reported HBV testing, whereas in Vancouver, 55% reported testing. HBV testing in Seattle was lower than in Vancouver, with a crude odds ratio of 0.73 (95% CI = 0.56, 0.94). However after adjusting for demographic, health care access, knowledge, and social support variables, we found no significant differences in HBV testing between the two cities. In our logistic regression model, the odds of HBV testing were greatest when the doctor recommended the test, followed by when the employer asked for the test. DISCUSSION Findings from this study support the need for additional research to examine the effectiveness of clinic-based and workplace interventions to promote HBV testing among immigrants to North America.

Abstract
Hepatitis B testing is recommended for immigrants from countries where hepatitis B infection is endemic. However, only about one-half of Chinese in North America have received hepatitis B testing. We conducted a randomized controlled trial to evaluate the effectiveness of a hepatitis B lay health worker intervention for Chinese Americans/Canadians. Four hundred and sixty individuals who had never been tested for hepatitis B were identified from community-based surveys of Chinese conducted in Seattle, Washington, and Vancouver, British Columbia. These individuals were randomly assigned to receive a hepatitis B lay health worker intervention or a direct mailing of physical activity educational materials. Follow-up surveys were completed 6 months after randomization. Self-reported hepatitis B testing was verified through medical records review. A total of 319 individuals responded to the follow-up survey (69% response rate). Medical records data verified hepatitis B testing since randomization for 9 (6%) of the 142 experimental group participants and 3 (2%) of the 177 control group participants (P = 0.04). At follow-up, a higher proportion of individuals in the experimental arm than individuals in the control arm knew that hepatitis B can be spread by razors (P < 0.001) and during sexual intercourse (P = 0.07). Our findings suggest that lay health worker interventions can impact hepatitis B-related knowledge. However, our hepatitis B lay health worker intervention had a very limited impact on hepatitis B testing completion. Future research should evaluate other intervention approaches to improving hepatitis B testing rates among Chinese in North America.

Abstract
BACKGROUND Chinese immigrants to North America experience cancer-related health disparities and underutilize preventive care. Little is known about Chinese immigrants' sources of health information. METHODS A population-based survey of Chinese immigrants was conducted in Vancouver, British Columbia, Canada and Seattle, Washington. RESULTS The study group included 899 individuals. Less than three fourths of the respondents reported receiving health information from health care providers, and only a minority used the Internet as a source of health information. We found significant differences between the sources of health information in Seattle and Vancouver. CONCLUSIONS Health educators should consider available media outlets as well as the characteristics of a target community when planning intervention programs for Chinese immigrants.

Abstract
Chinese immigrants to North America have substantially higher rates of chronic hepatitis B infection than the general population. One area for strategic development in the field of health education is the design and evaluation of English-as-a-Second language (ESL) curricula. The theoretical perspective of the Health Behavior Framework, results from a community-based survey of Chinese Canadian immigrants with limited English proficiency, and findings from focus groups of ESL instructors as well as Chinese ESL students were used to develop a hepatitis B ESL educational module. This research was conducted in Vancouver, BC. Survey data showed that less than three-fifths of the respondents had been tested for hepatitis B, and documented some important hepatitis B knowledge deficits. Further, only about one-quarter had ever received a physician recommendation for hepatitis B serologic testing. The ESL curriculum aims to both promote hepatitis B testing and improve knowledge, and includes seven different ESL exercises: Warm-up, vocabulary cards, information-gap, video, jigsaw, guided discussion, and problem/advice cards. Our quantitative and qualitative methods for curriculum development could be replicated for other health education topics and in other limited English speaking populations.

Abstract
BACKGROUND Viral hepatitis is the most common cause of liver disease in the world. In the past 25 years, vaccines have become available for two of the five hepatitis viruses, and, where implemented, vaccination has become a key component of hepatitis prevention. AIMS To provide an update on recent advances in the use of current hepatitis vaccines and to examine progress in the development of vaccines for the remaining hepatitis viruses. METHODS A Medline search was undertaken to identify the recent relevant literature. Search terms included hepatitis vaccines, hepatitis vaccination and hepatitis A-E vaccines. RESULTS Dramatic vaccine-induced declines in the incidence of both hepatitis A and B have occurred in the USA. Strategies to integrate hepatitis A vaccine into universal childhood immunization are being adopted. Similarly, strategies with the goal of eliminating transmission of hepatitis B have been promulgated. A vaccine for hepatitis E has been reported to be effective and safe, but progress in the development of vaccines for hepatitis C and D has been limited. CONCLUSION During the next few decades, the goals of eliminating hepatitis A and B virus transmission may be reached in the USA and elsewhere.
