Knowledge, attitudes and practices of hepatitis B prevention and immunization of pregnant women and mothers in northern Vietnam

Factors associated with hepatitis B knowledge among people of Vietnamese ethnicity in Australia

Despite high hepatitis B (HBV) prevalence among people of Vietnamese ethnicity in Australia and elsewhere, there is limited research on levels of HBV knowledge and factors associated with such knowledge. The aim of this study was to examine HBV knowledge and associated demographic and attitudinal factors among people of Vietnamese ethnicity in Australia. People of Vietnamese ethnicity (n = 966) were recruited through community events and social media groups to complete online surveys measuring HBV knowledge, attitudes towards HBV, levels of mistrust in Western medicine, and demographic characteristics. Findings of this study indicate that levels of knowledge are mixed, with gaps in knowledge related to transmission and treatment of the virus. Those with greater knowledge of HBV tended to be older, have higher levels of formal education, have been tested for HBV, and know someone living with HBV. Those with lower levels of knowledge tended to have more negative attitudes towards the virus and greater levels of mistrust in Western medicine. Given that health literacy is connected to effective communication from health providers, we suggest that there is a need for the development of health promotion and education resources targeted at people of Vietnamese ethnicity and translated into Vietnamese. We propose that such resources be developed in consultation with Vietnamese communities and health providers to ensure that they are culturally appropriate and sensitive to people of Vietnamese ethnicity living in Australia.

Sociodemographic Determinants of Knowledge, Attitudes, and Practices Toward Hepatitis B Infection Among Pregnant Women: A Cross-National Study in Jordan

Background Mother-to-child transmission (MTCT) of the hepatitis B virus (HBV) is significant, as most infants infected at birth go on to develop chronic hepatitis B. Vaccination and antiviral treatment during pregnancy could primarily prevent vertical transmission. Therefore, the purpose of this study is to assess pregnant Jordanian females' knowledge, attitude, and practices (KAP) toward HBV. In addition, to explore the relationship between the level of KAP toward HBV infection and its predictors. Methods Our cross-sectional study was conducted among pregnant women in Jordan. We enrolled 621 participants between January and April 2023. Our survey was derived from a previously validated tool that was used to investigate a similar aim as our study. The survey was done via Google Forms (Google LLC, Mountain View, California, United States) and it contained questions divided into four main sections: participants' demographics, knowledge section, attitudes section, and practices section. Results The majority of participants have neither a personal nor family history of HBV, and only 91 (14.7%) of the participants had a medical degree. The overall knowledge, attitude, and practice (KAP) scores were low, as only 176 (28.3%), 315 (50.7%), and 244 (39.3%) of participants achieved high levels of knowledge, attitude, and practice scores, respectively. A significant association was found between knowledge level, practice assessment, and the following variables: age, educational level, job, study field, history of HBV in the family, and source of knowledge. Regarding attitude, a significant association was found with the job, study field, and source of knowledge. Conclusion This study found that pregnant women in Jordan had a low level of awareness of HBV infection. Thus, more efforts should be made to raise awareness about HBV among high-risk groups, especially pregnant women.

Hepatitis B screening and knowledge among Chinese and Vietnamese students in Australia

Research has shown that there are significant gaps in hepatitis B knowledge among migrant communities who are at risk of hepatitis B, such as Chinese and Vietnamese communities. Many students studying within Australia come from countries with high prevalence of hepatitis B. However, there is very little research examining hepatitis B knowledge, screening, or vaccination among university students in Australia or worldwide. The aim of this paper was to measure both levels of and demographic differences in hepatitis B screening and knowledge among Chinese and Vietnamese students in Australia. Online surveys were completed by 112 Chinese- and 95 Vietnamese-identifying students in Australia, measuring knowledge of hepatitis B, engagement in screening and vaccination, and demographic characteristics. Results show that although engagement in screening and vaccination for hepatitis B was high, there were significant gaps in knowledge around transmission of hepatitis B. There were also some key demographic differences in screening and knowledge. For instance, those born in Australia were more likely to have been screened compared to those born Mainland China, Hong Kong, or Vietnam. Chinese students born in Australia had lower levels of knowledge compared to those born in Mainland China or Hong Kong. Among both samples, knowing someone living with hepatitis B was associated with higher levels of knowledge. Findings underscore the need for education-based interventions to address the significant gaps that exist in knowledge around hepatitis B, with a specific need for culturally appropriate resources in a range of languages to cater to the diverse communities who may be at risk of hepatitis B.

Knowledge and Willingness to Utilize Hepatitis B Preventive Measures among Pregnant Women in Ado-Ekiti, Southwest, Nigeria

Introduction

Mother-to-child transmission remains an important mode of transmission of hepatitis B infection particularly in endemic areas. The knowledge and practices of pregnant women about mother-to-child transmission (MTCT) of hepatitis B virus (HBV) may influence the uptake of strategies to reduce mother-to-child transmission of infection.

Objectives

This study assessed the knowledge and willingness to uptake hepatitis B virus infection preventive services among pregnant women in Ado-Ekiti, Nigeria.

Methods

This was a cross-sectional study that involved 373 pregnant women at the Ekiti State University Teaching Hospital (EKSUTH) and Maternal Child Specialist Clinics, Ado-Ekiti, Nigeria. A structured questionnaire was used to assess their knowledge, practices, and perceptions about MTCT of hepatitis B infection.

Results

Only 52.5% (196) of the respondents had good knowledge, although the majority 290 (77.7%) had heard of hepatitis B infection prior to the survey. Only 147 (39.4%) of the respondents had ever had hepatitis B screening. More persons with professional jobs had good knowledge about hepatitis B infection compared with other occupations (p < 0.001). However, more respondents aged 30-34 years had poor knowledge about hepatitis B infection compared with other age groups (p = 0.045). Respondents with good knowledge about hepatitis B infection were willing to uptake hepatitis B infection prevention services (p < 0.001).

Conclusion

This study showed that respondents with professional jobs had good knowledge about hepatitis B infection and those who had good knowledge about the infection were willing to utilize hepatitis B preventive measures. Awareness of MTCT of HBV did not translate into good practice as only few respondents had screened for hepatitis B. There is a need to intensify education about modes of transmission of hepatitis B infection with an emphasis on promoting good preventive practices.

Perceived risk factors and preventive practices of Hepatitis B viral infection among pregnant women in Nigerian hospitals: A cross-sectional study

OBJECTIVE

The study assessed the perceived risk factors and prevention practices of HBV infection among pregnant women in Nigerian hospitals.

STUDY DESIGN

A descriptive cross-sectional study was conducted among 343 pregnant women attending antenatal clinics at two purposefully selected primary health care centers in Ile-Ife. Women were included in the study using systematic sampling. A structured researcher-administered questionnaire was used for data collection. Descriptive and inferential (Chi-square test and Logistic regression) statistical analysis were carried out.

RESULTS

More than half (53%) of the respondents had a low perceived risk for hepatitis. Majority (73.5%) had been screened for HBV during the index pregnancy but only 30% received complete doses of HBV vaccine. Respondents who underwent HBV screening during pregnancy (OR = 2.06, 95% CI = 0.94 - 4.5), who had completed Hepatitis B vaccination had reduced odds ratios for perceiving risk factors for Hepatitis B Viral Infection (OR = 0.224, 95% CI = 0.94 - 4.5).

CONCLUSION

Pregnant women had a low-risk perception of HBV infection. The low level of risk perception can serve as a basis for developing preventive interventions aimed at educating and empowering expectant mothers in order to prevent HBV infection and its transmission to their children.

Barriers to and Facilitators of Hepatitis B Vaccination among the Adult Population in Indonesia: A Mixed Methods Study

To reach the goals of the Global Hepatitis Elimination 2030 program, Indonesia is now preparing a new regulation for hepatitis B vaccinations for adult population. This study aimed to determine the factors influencing vaccine uptake for hepatitis B in the adult population, and identify barriers to, and facilitators of, hepatitis B vaccination programmes. An explanatory sequential mixed methods design was implemented in this study. We conducted a survey involving 893 participants in the general population followed by 14 in-depth interviews with health providers. The survey found that only 15% (95% confidence interval 13-18%) of participants received at least one dose of the hepatitis B vaccine. Factors associated with vaccine uptake were, living in Yogyakarta compared to living in Aceh, having secondary and higher education compared to primary education, working as a health worker compared to working in other sectors, and having health insurance that covered hepatitis B vaccination compared to not having such health insurance. Our qualitative study also identified several barriers to the adult hepatitis B vaccination programme in Indonesia such as the high cost of vaccination, lack of vaccine availability in certain areas, limited human resources to implement the hepatitis B vaccination programme, and the ineffective dissemination of hepatitis B vaccination. This study highlights that accessibility and affordability of vaccinations are important determinants of vaccination uptake that should be taken into account when planning vaccination campaigns.

Dynamics of Hepatitis B infection prevention practices among pregnant women attending antenatal care at Lubaga Hospital Kampala, Uganda using the constructs of information-motivation-behavioural skills model

BACKGROUND

Hepatitis B virus (HBV) infection is considered a significant global public health challenge with infectivity as well as estimated potential for transmission more than 50 to 100 times that of HIV. Over time, numerous empirical studies have shown that majority of HBV-related yearly global deaths are secondary to carcinoma of the liver. It is also known that HBV infected Women have the potential to transmit the infection vertically to their infants during pregnancy. This accounts for the WHO reported 3.16% prevalence among children less than 5 years of age in Uganda. This study assessed the predictors of HBV infection prevention practices among eligible consenting pregnant women using Lubaga health facility for antenatal care (ANC).

METHODS

A cross-sectional descriptive study employing quantitative data collection based on the constructs of IMB model was used to capture data on the study variables among 385 randomly selected eligible pregnant women attending antenatal care at Lubaga hospital between September 2020 and October 2020. Data derived from the quantitative instrument was analysed by data reduction and transformation to summaries of descriptive statistics using (SPSS version 26) and regression analysis was performed to establish characteristics of the association between the variables with significance level set as (p < 0.05). Chi-square goodness-of-fit test was employed for significant differences in the proportion of dichotomous responses.

RESULTS

The findings showed that more than half of the respondents (59%) were between the ages of 18 and 28 and majority of them (42.3%) had secondary education. Furthermore, an average but inadequate knowledge ([Formula: see text] 5.97 ± 6.61; B = 0.57; p < .001), positive perception ([Formula: see text] 17.10 ± 18.31; B = 0.97; p = .014) and good behavioural skills ([Formula: see text] 12.39 ± 13.37; B = 0.56; p < .001) for adopting prevention practices all statistically predicted the averagely acceptable level of prevention practices ([Formula: see text] 15.03 ± 16.20) among the study respondents as measured on rating scales of 12, 33, 21 and 30 respectively.

CONCLUSION AND RECOMMENDATION

There were observed gaps in their knowledge about some basic features of the infection like transmission and risk factors as well as some misperceptions about vaccination despite the relatively average score level for both, which is likely to influence their prevention behaviours and predispose them to the risk of the infection if actions are not taken. Therefore, personalized health education is needed during antenatal visits and subsequent health campaign in order to inform better prevention practices among this vulnerable population group.

A systematic review to determine the anti-vaccination thoughts of pregnant women and the reasons for not getting vaccinated

The aim of this study was to determine the anti-vaccination thoughts of pregnant women and the reasons for not getting vaccinated. In this study, data was obtained by retrospectively scanning the cross-sectional and qualitative studies published in the databases of 'PubMed, Cochrane, EBSCOhost, ULAKBİM and Google Scholar' in Turkish and English languages between 2011-2021. The PRISMA method was used in the preparation of the systematic review. In the studies reviewed, it was determined that the rate of pregnant women who were against the vaccine ranged from 6.2% to 98.6%, and the opinions of pregnant women against vaccination and the reasons for not getting vaccinated are presented under seven themes. The results of the study were considered important in terms of showing that quality and important studies were carried out in the literature on the subject and that the data were presented.IMPACT STATEMENTWhat is already known on this subject? Today, with the global coronavirus pandemic, vaccines and their effects are on the agenda again. Especially in pregnant women, opposition to vaccination and not getting vaccinated have emerged for various reasons.What do the results of this study add? The anti-vaccine thoughts of the pregnant women and the reasons for not getting vaccinated were mostly as follows: insufficient level of knowledge, mistrust of vaccines, perception of low infection risk, misconceptions and beliefs about the safety, content, side effects and efficacy of vaccines, worry and fear about the side effects of vaccines, the thought that the vaccine will harm herself and the baby, causes arising from healthcare professionals, financial, temporal and logistical barriers.What the implications are of these findings for clinical practice and/or further research? Scientific studies that can provide comprehensive and strong evidence about vaccine hesitancy and its causes, methods of increasing social approval in vaccination, and solutions should be proposed in the light of these researches in the fight against vaccine rejection.

Hepatitis B and pregnancy: understanding the experiences of care among pregnant women and recent mothers in metropolitan Melbourne

Background

Pregnant women are a priority group for hepatitis B testing. Guideline-based care during antenatal and post-partum periods aims to prevent mother-to-child transmission of hepatitis B virus and lower the risk of liver complications in mothers. This qualitative study explored knowledge of hepatitis B and experiences of hepatitis B related care among pregnant women and mothers.

Methods

Semi-structured interviews were conducted with thirteen women with hepatitis B who were attending antenatal or post-partum hepatitis B care. The interviews were thematically analysed to assess knowledge and understanding of hepatitis B. Participants were recruited from specialist clinics in metropolitan Melbourne between August 2019 and May 2020.

Results

Four major themes were identified from interviews: (1) knowledge and understanding of hepatitis B, (2) treatment pathways, (3) accessing hepatitis B related care, and (4) disclosing status to friends. Most participants displayed an understanding of hepatitis B transmission, including mother to child transmission. The main motivator of post-partum attendance was reassurance gained concerning their child’s health. Sources of hepatitis B information included doctors, online information and family. Participants identified parents and siblings as sources of support and reported an unwillingness to disclose hepatitis B status to friends.

Conclusions

Women attending antenatal or post-partum care reported having overall positive experiences, particularly regarding reassurance of their child’s health, but displayed misconceptions around horizontal transmission. Knowledge gained from these results can contribute to the development of targeted models of care for pregnant women and mothers with young children to ensure their successful linkage to care.

Contextual and individual factors associated with knowledge, awareness and attitude on liver diseases: A large-scale Asian study

There are limited data to provide better understanding of the knowledge/awareness of general population towards liver health in Asia. We sought to identify the knowledge gaps and attitudes towards liver health and liver diseases as well as evaluate associated individual-level and macro-level factors based on contextual analysis. An online survey assessing knowledge, awareness and attitudes towards liver health and disease was conducted among 7500 respondents across 11 countries/territories in Asia. A liver index was created to measure the respondents' knowledge level and the degree of awareness and attitudes. Multilevel logistic regression was performed to identify individual factors and contextual effects that were associated with liver index. The overall liver index (0-100-point scale) was 62.4 with 6 countries/territories' liver indices greater than this. In the multilevel model, the inclusion of geographical information could explain for 9.6% of the variation. Residing in a country/territory with higher HBV prevalence (80% IOR: 1.20-2.79) or higher HCV death rate (80% IOR: 1.35-3.13) increased the individual probability of obtaining a high overall liver index. Individual factors like age, gender, education, household income, disease history and health screening behaviour were also associated with liver index (all p-values<0.001). The overall liver index was positively associated with the two macro-level factors viz. HBV prevalence and HCV death rate. There is a need to formulate policies especially in regions of lower HBV prevalence and HCV death rate to further improve the knowledge, awareness and attitudes of the general public towards liver diseases.

Low knowledge about hepatitis B prevention among pregnant women in Kinshasa, Democratic Republic of Congo

Infants infected perinatally with hepatitis B (HBV) are at the highest risk of developing chronic hepatitis and associated sequelae. Prevention of mother-to-child transmission (PMTCT) of HBV requires improved screening and awareness of the disease. This study evaluated existing HBV knowledge among pregnant mothers (n = 280) enrolled in two HBV studies in urban maternity centers in Kinshasa, Democratic Republic of the Congo. All mothers responded to three knowledge questions upon study enrollment. Baseline levels of knowledge related to HBV transmission, treatment, prevention, and symptoms were low across all participants: 68.8% did not know how HBV was transmitted, 70.7% did not know how to prevent or treat HBV MTCT, and 79.6% did not know signs and symptoms of HBV. Over half of participants responded "I don't know" to all questions. HBV-positive women who participated in both studies (n = 46) were asked the same questions during both studies and showed improved knowledge after screening and treatment, despite no formal educational component in either study (p < 0.001). These findings highlight the need for intensified education initiatives in highly endemic areas to improve PMTCT efforts.

Risk factors associated with hepatitis B virus infection among pregnant women attending the antenatal care unit of the Bamenda Regional Hospital

Objectives

Approximately 257 million people are infected with hepatitis B virus (HBV) especially in the middle and low-income countries, despite the Global Health Sector Strategy on viral hepatitis 2016–2021 which aims to eliminate viral hepatitis as a public health threat by 2030. Hepatitis B virus (HBV) remains a common public health problem in Cameroon with a high prevalence among pregnant women. Therefore, this study was designed to assess risk factors associated with hepatitis B virus infection among pregnant women attending the antenatal care unit of the Bamenda Regional Hospital.

Study design

The study was a health facility-based cross-sectional study carried out from March to May 2020. The inclusion criteria were all pregnant women who came for their first visit.

Methods

A well-structured questionnaire and laboratory test methods were used to collect data from 221 pregnant women who were consecutively enrolled in the study. The OnSite HBsAg Rapid Test (source: CTK Biotech, Inc. REF: R0040), was used to detect HBsAg in serum. Both descriptive statistics and Chi-square (and Fisher's exact) test were used for data analysis.

Results

The prevalence of HBV infection among pregnant women was 4.98% (11/221). Although knowledge, attitude and practice towards HBV by pregnant women were not significantly associated with the risk of infection, there were higher odds of poor practice (P = 0.0152) and attitudes (P = 0.0016) among those without knowledge on HBV infection.

Conclusions

Free of charge vaccination for those with negative HBsAg test results and extensive health education campaigns against HBV is recommended among pregnant women attending the antenatal care unit of the Bamenda Regional Hospital.

A Survey of the Knowledge of and Testing Rate for Hepatitis C in the General Population in South Korea

Background/Aims

To eliminate hepatitis C virus (HCV) infection, improving public knowledge of and access to HCV screening and treatment is essential. The aim of this study was to evaluate the knowledge of and testing rate for HCV and the opinions about the inclusion of the HCV test in the National Health Examination (NHE) among the general population in South Korea.

Methods

A telephone interview survey was conducted by an independent research company using a 16 item-questionnaire (demographics, knowledge of HCV, testing and results, need for screening) in May 2019. The sample population consisted of 1,003 adult Korean residents adjusted by age, sex, and area according to the standard Korean population in 2019.

Results

Among the 1,003 participants (505 women, mean age of 47.9 years), 56.4% recognized HCV; 44.4% understood that HCV is transmittable, and 56.8% thought that HCV is curable by medication. The recognition rate tended to increase with an increasing level of education. Testing for anti-HCV antibodies was reported by 91 people (9.1%); among them, 10 people (11.0%) reported a positive result, and eight people received treatment. The common reasons for HCV testing were a health check-up (58.5%), a physician's recommendation (11.0%) and elevated liver enzyme levels (10.7%). The majority of the population (75.1%) agreed with the integration of HCV into the NHE.

Conclusions

The level of knowledge of HCV is suboptimal, and the self-reported testing rate for HCV is less than 10%; however, once HCV infection is diagnosed, the treatment rate seems to be high in South Korea. More active campaigns and effective screening are needed.

A mixed-methods evaluation of hepatitis B knowledge, attitudes, and practices among migrant women in Thailand

BACKGROUND

Globally 90 % of transmission of Hepatitis B virus (HBV) is from mother-to child and occurs predominantly in resource limited countries where the prevalence of HBV is high. Transmission could be interrupted by timely vaccinations but coverage remains problematic in these areas. Low knowledge or awareness of HBV may play a part in low vaccination coverage. This study examines the provision of antenatal care counselling with a focus on HBV in two different regions of northern Thailand, Sarapee Hospital (SH), Chiang Mai, and Shoklo Malaria Research Unit (SMRU), Tak Province.

METHODS

A mixed-methods sequential explanatory study design was used to evaluate antenatal services for migrants. Cross-sectional knowledge, attitude and practice (KAP) surveys were conducted immediately after counselling at first ANC contact, at 3-6 months after first ANC contact and at delivery. Surveys provided quantitative data, and qualitative methods included observations, focus group discussions (FGD) and in-depth interviews (IDI); analysed thematically to explore concepts of knowledge and understanding, attitude and practice of pregnant women and providers.

RESULTS

Between September-2019 and May-2020, 757 women participated to KAP surveys, and 31 observations of counselling, 16 FGD and 9 IDI were conducted. KAP surveys showed in spite of low knowledge about HBV transmission, infection, or vaccination (correct response: SH 5.7 %, 9/157; SMRU 34.0 %, 204/600), most women (≥ 93 %, either site) understood they were screened for HBV and were willing to vaccinate infants for HBV. In explaining KAP survey results, qualitative analysis suggests counselling should: use the appropriate language; be tailored to the local health literacy level, provide only pertinent information, be repeated over the antenatal period; and attempt to ensure patient privacy (where possible). Programme effectiveness benefits from positive attitudes to screening and vaccinations and a high level of trust in the providers nevertheless participants provided good suggestions for improvements of the service.

CONCLUSIONS

Limited knowledge of HBV among migrant women can be improved by counselling that emphasizes actionable knowledge such as vaccination schedule. Key improvements to the counselling process include training counsellors to conduct interactive counselling sessions in the woman's language, using appropriate visual aids and timely repetition over the course of the antenatal period.

Hepatitis B birth dose vaccination for newborns in Uganda: A qualitative inquiry on pregnant women's perceptions, barriers and preferences

BACKGROUND

Sub-Saharan Africa continues with very low hepatitis B (HBV) birth dose vaccination coverage. To guide policy on HBV vaccine for newborns, we explored perceptions, barriers and preferences of pregnant women regarding HBV and the HBV birth dose vaccination.

METHODS

We conducted eight focus groups discussions (FGDs) among 70 pregnant women, stratified by rural-urban residence, age and education level, using a structured focus group discussion guide to explore birth dose awareness, perceptions, barriers and preferences. Data were transcribed, coded and analysed using framework analysis.

RESULTS

Perceptions related to HBV and liver cancer causes and prevention were diverse; most FGD participants did not perceive illnesses as distinctly different. Older women-groups, both urban and rural, had never heard about HBV, but were aware of liver cancer, viewing the disease as fatal. No FGD participants were aware of HBV birth dose. Concerns included vaccine safety, its availability to women who deliver outside the health system and mistrust in health-care worker (HCWs) when handling newborns. Rural-dwelling groups perceived absence of HBV services, while FGDs with young participants believed vaccine side-effects hampered birth dose planning. Most women-groups preferred (i) oral to injectable vaccines; (ii) receiving birth dose education during antenatal, to media-based education; (iii) that newborns receive the birth dose immediately after delivery in the mother's presence.

CONCLUSION

Although the birth dose is acceptable among pregnant women, planners need to continuously engage them as key stakeholders during planning to address concerns, in order to raise confidence, maximize uptake and strengthen HBV eradication efforts.

Comparing Australian health worker and student attitudes and concerns about providing care to people living with hepatitis B

ISSUE ADDRESSED

Hepatitis B (HBV) is a major public health issue with over 250 million people chronically infected worldwide. In Australia, prevalence is higher among migrant communities and these groups may be reticent to attend health care services due to concerns about experiencing stigma and discrimination. The way health workers perceive their clients, particularly those of migrant backgrounds, may influence the way they treat these clients and the quality of care provided. This study investigated and compared the attitudes and concerns health workers and health students have towards working with clients living with HBV.

METHODS

Health workers (n = 551) and students (n = 199) completed an online survey which investigated attitudes towards people living with HBV, comfort with providing care for these clients and concerns they have about working with them.

RESULTS

Health students expressed less comfort (U = 47 611, z = -2.73, P = .006) and reported more concerns about working with people with HBV than qualified health workers (U = 61611.50, z = 2.64, P = .008). Students' concerns were centred around their own ability to provide care rather than issues related to clients. There were no differences in overall attitudes towards people living with HBV between health workers and students.

CONCLUSION

To address concerns that health workers and students may have in working with people living with HBV, particularly those from migrant communities, and to ensure that health workers feel comfortable and confident, HBV workforce development should be included in undergraduate and postgraduate training programmes as well as in continuing professional education. SO WHAT?: This will assist the health workforce to develop competency in the treatment of people living with HBV, with the ultimate aim of providing best quality, non-judgemental care to all people living with HBV.

Knowledge, Attitude, and Associated Factors Towards Vertical Transmission of Hepatitis B Virus Among Pregnant Women Attending Antenatal Care in Tertiary Hospitals in Amhara Region, Northwest Ethiopia: A Cross-Sectional Study

PURPOSE

Hepatitis B virus (HBV) infection is a major public health problem globally. Mother-to-child transmission (MTCT) of HBV is high in endemic countries; however, little is known about pregnant women`s knowledge and attitudes regarding MTCT and prevention methods in Ethiopia. Therefore, this study aimed to assess the knowledge, attitude and associated factors of pregnant women towards MTCT of HBV and its prevention in three tertiary hospitals in the Amhara region, northwestern Ethiopia.

MATERIALS AND METHODS

A cross-sectional study was conducted from May 1, 2018 to September 30, 2019. A total of 1121 pregnant women participated in the study. A structured questionnaire was used to collect the sociodemographic, knowledge, and attitudes of pregnant women towards MTCT of HBV and its prevention. Data were analyzed using SPPS version 20. χ 2-test, multivariate logistic regression, Spearman correlation, and analysis of variance (ANOVA) were used for data analysis.

RESULTS

The majority of 89.6%; 95% CI (87.9-91.3%) pregnant women had poor knowledge of MTCT of HBV and its prevention. However, more than half of the study participants had favorable attitudes. Only 141 (12.6%) of the pregnant women knew that HBV transmitted from mother-to-child and 169 (15.1%) knew that HBV had a vaccine. There was a significant difference in attitude between the three hospitals (P<0.001). In multivariable analysis, education, gravida and vaccination history were independent factors significantly associated with good knowledge and favorable attitudes while income and residence significantly associated only to knowledge and attitude, respectively. There was a significant positive correlation between the knowledge and attitude of pregnant women (P<0.001).

CONCLUSION

The knowledge of pregnant women was found to be poor and their attitude was also limited to MTCT of HBV infection and its prevention. Educational status and vaccination history were predictors of knowledge and attitude, but income and residence only to knowledge and attitude, respectively. This study revealed a lack of knowledge in pregnant women for the prevention and control of MTCT of HBV. This calls for the Amhara Health Bureau and Ministry of Health to promote health education programs for pregnant women attending antenatal care on MTCT of HBV and its prevention methods to improve knowledge and attitudes.

Hepatitis B Infection and Mother-to-Child Transmission in Haiphong, Vietnam: A Cohort Study with Implications for Interventions

Background

There is little data available on HBV infection and mother-to-child transmission (MTCT) in Vietnam.

Objective

This study is aimed at assessing the prevalence of HBV infection and the current situation of MTCT in Haiphong, Vietnam.

Methods

A transversal survey of 1721 pregnant women followed by an observational prospective cohort study of 183 HBV-infected women was conducted at Haiphong Gyneco-Obstetric Hospital. Women were followed up up to 12-month postpartum; use of prevention measures and the MTCT rate were evaluated. HBV infection in children was defined by a HBsAg-positive test at 12 months of age.

Results

At baseline, 183 of 1721 pregnant women (10.6%) tested HBsAg positive. Among them, 23.0% were HBeAg positive, 26.2% had a detectable load of HBV DNA, and 13.1% had a HBV DNA load ≥ 200,000 IU/mL. All women underwent MTCT prevention antiviral therapy. At delivery, 98.9% of newborns receive a HBV vaccine birth dose, and 82% received HBIG. At 12 months of age, 94.7% have received the scheduled HBV vaccines. Eight percent of infants born from followed-up women were HBsAg positive. The mother's HBeAg-positive status was associated with a higher risk of HBV infection in infants.

Conclusion

The HBV prevalence and MTCT rates are high in Haiphong. A strong national plan to increase the access to preventive measures and to monitor results is needed in order to decrease this prevalence.

Perception of and Attitude towards Hepatitis B Infection among Saudi Pregnant Females Attending Antenatal Care Unit in Al-Ahsa City, Kingdom of Saudi Arabia

Objective This study aimed to assess the knowledge and attitudes of pregnant females in Al-Ahsa city, Kingdom of Saudi Arabia (KSA) toward hepatitis B virus infection. Methods A cross-sectional study was done at the Maternity and Children's Hospital, Al-Ahsa. A total of 422 of every third pregnant women were recruited from 6/12/2019 to 20/12/2019. Self-administered questionnaire was provided that contained three aspects: sociodemographic, perception and source of information about hepatitis B, and attitude toward hepatitis B infection. Analysis was performed using SPSS version 21 (IBM Corp., Armonk, NY). Results A total of 422 pregnant women participated in this study with a response rate of 93.7%. Among them, 44.79% had a university degree or higher education level, about 82% had information about hepatitis B virus (HBV) during their pregnancy, 0.9% knew a person with HBV, 48.1% knew that hepatitis B is caused by virus, 72% knew that hepatitis B has vaccine, 41.9% knew that hepatitis B spreads via mother, 79.6% were willing to do hepatitis B test during pregnancy, 80.1% were willing to allow for kids' vaccination against HBV, and 83.4% were willing to allow their kids for hepatitis B testing. There was a significant relationship between the level of education and the knowledge score. And there was a significant relationship between the level of education and attitudes score. Conclusion There is insufficient knowledge among pregnant women regarding hepatitis B infection, while pregnant women showed remarkably positive attitudes regarding therapy and immunization. So, we highly recommend for awareness campaigns about viral hepatitis regarding means of transmission, and possible treatment options.

Knowledge, Attitude, and Practice towards Hepatitis B Virus among Pregnant Women Attending Antenatal Care at the University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia

BACKGROUND

Hepatitis B virus (HBV) infection remains a serious public health concern worldwide. Mother-to-child transmission (MTCT) is the major mode in endemic areas, including Ethiopia, where little is known about pregnant women's knowledge, attitudes, and practice towards HBV infection and MTCT. Therefore, the study is aimed at determining the knowledge, attitude, and practice towards HBV among pregnant women attending antenatal care.

METHOD

A cross-sectional study was conducted from February to April 2018, at the University of Gondar Comprehensive Specialized Hospital. A total of 354 pregnant women were selected by systematic random sampling and included in this study. KAP of participants on HBV MTCT was assessed using a structured questionnaire. Data was analyzed using SPSS version 22 software.

RESULT

The total response rate was 100% (354/354). Out of the 354 participants, 73.4% were within the poor knowledge. Only 18.9% of the respondents know HBV can be transmitted from mother to child during pregnancy. Less than half (43.8) of the participants think that they will never be infected with HBV, and 47.7% of them go to traditional healers when they have symptoms of HBV. Majority of the respondents (85.87%) had never screened for HBV, and only 28.5% of the participants believed that hepatitis B can cause liver cancer. In multivariable analysis, residence, income, and educational level were associated with mean score knowledge and attitude.

CONCLUSIONS

Knowledge about HBV among pregnant women was found to be poor, and their attitude and practice were also limited. Therefore, extensive health education program should be given to the pregnant women to increase their awareness towards HBV infection. All pregnant women should be screened for HBV as part of ANC follow-up.

Knowledge, attitudes and medical practice regarding hepatitis B prevention and management among healthcare workers in Northern Vietnam

BACKGROUND AND AIM

Vietnam's burden of liver cancer is largely due to its high prevalence of chronic hepatitis B virus (HBV) infection. This study aimed to examine healthcare workers' (HCWs) knowledge, attitude and practices regarding HBV prevention and management.

METHODS

A cross-sectional survey among health care workers working at primary and tertiary facilities in two Northern provinces in Vietnam in 2017. A standardized questionnaire was administered to randomly selected HCWs. Multivariate regression was used to identify predictors of the HBV knowledge score.

RESULTS

Among the 314 participants, 75.5% did not know HBV infection at birth carries the highest risk of developing chronic infection. The median knowledge score was 25 out of 42 (59.5%). About one third (30.2%) wrongly believed that HBV can be transmitted through eating or sharing food with chronic hepatitis B patients. About 38.8% did not feel confident that the hepatitis B vaccine is safe. Only 30.1% provided correct answers to all the questions on injection safety. Up to 48.2% reported they consistently recap needles with two hands after injection, a practice that would put them at greater risk of needle stick injury. About 24.2% reported having been pricked by a needle at work within the past 12 months. More than 40% were concerned about having casual contact or sharing food with a person with chronic hepatitis B infection (CHB). In multivariate analysis, physicians scored significantly higher compared to other healthcare professionals. Having received training regarding hepatitis B within the last two years was also significantly associated with a better HBV knowledge score.

CONCLUSIONS

Findings from the survey indicated an immediate need to implement an effective hepatitis B education and training program to build capacity among Vietnam's healthcare workers in hepatitis B prevention and control and to dispel hepatitis B stigma.
