Study on Status and Willingness towards Hepatitis B Vaccination among Migrant Workers in Chongqing, China: A Cross-Sectional Study

Background: Rural-to-urban migrant workers may serve as a bridge population for the cross-regional spread of hepatitis B vaccination (HBV) due to frequent shifts between their work areas and homelands, and they are less likely to be covered by the national hepatitis B (HB) immunization program. This study aimed to investigate the current inoculation status of HB vaccine among migrant workers and the willingness to be vaccinated among non-vaccinated ones. Methods: We conducted a cross-sectional survey using anonymous interviews with migrant workers selected by two-stage cluster sampling from July to December 2018. Binary logistic regression models were adopted to detect influencing factors associated with HB inoculation status and vaccination willingness. Results: 1574 respondents were recruited in the surveys, and 773 (49.11%) respondents reported that they had been inoculated with HB vaccine. Only 285 (35.58%) non-vaccinated respondents were willing to be inoculated. Logistic regression indicated that younger age, higher education level, less wearing of condoms, higher knowledge scores of HB, and higher risk perception of HBV infection were positively associated with inoculation of HB vaccine. Respondents who were more highly educated, and drinkers, with higher knowledge scores of HB and with higher risk perception of HBV infection were more willing to be vaccinated. Conclusions: the HB vaccination rate of migrant workers in Chongqing was relatively low and only a small section of non-vaccinated migrant workers had vaccination willingness. Health interventions and policies are needed to improve knowledge and cognition of HB among migrant workers, particularly for those who are older, less educated, poor in HB knowledge, less likely to wear condoms, and non-drinkers. Peer education, as well as the combination of traditional and new media, would be accessible and effective ways to disseminate HB related knowledge for migrant workers.

Coverage Rates

Hepatitis B vaccination coverage rates are low throughout most populations in China. Factors influencing low coverage rates, including population-specific hepatitis B vaccination barriers, may inform policies that promote vaccination. A cross-sectional survey of residents from 43 communities assessed their vaccination status and identified associated factors via uni- and multivariable logistic regression and subgroup analyses. In total, 11,280 of 36,007 respondents received a hepatitis B vaccine, indicating a 31.33% coverage rate. Multivariable logistic regression revealed non-Beijing (odds ratio (OR) = 0.81; 95% confidence interval (CI): 0.76–0.85) and residents who self-rated their health as very healthy (OR = 0.82; 95% CI: 0.68–0.99) were unlikely to be vaccinated. Farmers (OR = 1.68; 95% CI: 1.51–1.86), commerce and service workers (OR = 1.82; 95% CI, 1.63–2.04), government employees (OR = 1.56; 95% CI: 1.38–1.77), professionals and technicians (OR = 1.85; 95% CI: 1.63–2.09), and students (OR = 1.69; 95% CI: 1.10–2.59) had increased hepatitis B vaccination rates. The multivariable assessment revealed hepatitis B vaccination coverage rates are associated with confirmed or suspected family cases, vaccination unwillingness or uncertainty, and unawareness of its prevention of the hepatitis B virus. Low hepatitis B vaccination coverage rates among Beijing subpopulations highlight the need for improved strategies, including those that target specific populations.

INTRODUCTION: A decline in hepatitis D virus (HDV) occurrence was described in Europe and Asia. We estimated HDV prevalence in the Brazilian Amazon following hepatitis B vaccination. METHODS: This is a cross-sectional survey of HDV measured by total antibodies to HDV (anti-HD T). RESULTS: HDV prevalence was 41.9% whiting HBsAg carries and was associated with age (PR = 1.96; 95% CI 1.12-3.42; p = 0.01), hepatitis B virus (HBV) infection (PR = 4.38; 95% CI 3.12-6.13; p < 0.001), and clinical hepatitis (PR =1.44; 95% CI 1.03-2.00; p = 0.03). Risk factors were related to HDV biology, clinical or demographic aspects such as underlying HBV infection, clinical hepatitis and age. CONCLUSIONS: Our study demonstrated that HDV infection continues to be an important health issue in the Brazilian Amazon and that the implementation of the HBV vaccination in rural Lábrea had little or no impact on the spread of HDV. This shows that HDV has not yet disappeared from HBV hyperendemic areas and reminding that it is far from being a vanishing disease in the Amazon basin.

Detailed knowledge about hepatitis B virus (HBV) vaccination coverage and timeliness for sub-Saharan Africa is scarce. We used data from a community-based cross-sectional survey conducted in 2018–2019 in the area of Niakhar, Senegal, to estimate coverage, timeliness, and factors associated with non-adherence to the World Health Organisation-recommended vaccination schedules in children born in 2016 (year of the birth dose (BD) introduction in Senegal) and 2017–2018. Vaccination status was assessed from vaccination cards, surveillance data, and healthcare post vaccination records. Among 241 children with available data, for 2016 and 2017–2018, respectively, 31.0% and 66.8% received the BD within 24 h of birth (BD schedule), and 24.3% and 53.7% received the BD plus at least two pentavalent vaccine doses within the recommended timeframes (three-dose schedule). In logistic regression models, home birth, dry season birth, and birth in 2016 were all associated with non-adherence to the recommended BD and three-dose schedules. Living over three kilometres from the nearest healthcare post, being the firstborn, and living in an agriculturally poorer household were only associated with non-adherence to the three-dose schedule. The substantial proportion of children not vaccinated according to recommended schedules highlights the importance of considering vaccination timeliness when evaluating vaccination programme effectiveness. Outreach vaccination activities and incentives to bring children born at home to healthcare facilities within 24 h of birth, must be strengthened to improve timely HBV vaccination.

Background: Cervical cancer (CC) ranks the eighth most frequent cancer among Syrian women with crude incidence rates 1.4 per 100, 000 populations per year. This study aimed to test the acceptance of the human papillomavirus (HPV) vaccine among mothers of schoolgirls in sixth-grade class. Methods: A cross-sectional survey was conducted through a structured and self-administrated questionnaire. A total of 400 Syrian mothers of schoolgirls were selected randomly by the cluster sampling method in Aleppo city, Syria, in 2011. Significant variables from univariate analysis were included in an enter technique multiple logistic regression analysis. Results: The response rate was 86%. If the vaccine was free, 282 (81.7%) mothers would accept the vaccine for themselves and 236 (68.4%) for their daughters, respectively. However, the acceptance rate grossly decreased to 24.6% and 15.1%, respectively, if the vaccine was not provided free. The high cost of the HPV vaccine and lack of knowledge were the significant barriers for mothers' acceptance of the HPV vaccine. Protection of daughters and the trust with health authority were the main encouraging reasons to accept the HPV vaccine. Findings from logistic regression analysis revealed that the employed mothers (odds ratio = 2.4; 95% CI: 1.3–4.4), with a positive history of gynecological examination (OR = 2.1; 95% CI: 1.6–2.9) and having sound knowledge (OR = 2.4; 95% CI: 1.0–5.7) are independent factors related to the acceptance of the HPV vaccine for their daughters. Conclusion: The results from this study suggest that mothers from different cultural backgrounds, including Syrian mothers, are holding different beliefs on privacy and health that may affect their willingness to accept the HPV vaccine.

Introduction: Male migrants and their sexual partners at home are at increased risk of STIs (Sexually Transmitted Infections) including HIV (Human Immunodeficiency Virus). We aimed to assess the knowledge and attitudes of migrants’ wives regarding HIV and STIs, and to understand risk perception of HIV due to their husbands’ sexual behaviour. Methodology: A cross-sectional survey among 182 migrants’ wives was conducted in two rural villages of Chitwan district in Nepal. The participants were selected through multistage cluster sampling method and data were collected through a questionnaire administered through a face-to-face interview. Results: Nearly all (94%) of migrants’ wives had a good knowledge of HIV, however with some misconceptions. More than two-thirds of the participating migrants’ wives were aware about the risk of HIV infection in migrant husbands and subsequent risk of transmitting themselves through sexual intercourse. Nearly half of the participants reported inability to ask their husbands about HIV and STIs even if they had their doubts. Knowledge of HIV and HIV risk associated with migration were statistically significantly higher in younger women, those who were literate and the longer the period of their husbands’ migration. Conclusion: Despite having generally a good knowledge and awareness of HIV and migration induced HIV risk; migrants’ wives could not discuss sexual health issues with their husbands, thus increasing their vulnerability to HIV and STIs.SAARC J TUBER LUNG DIS HIV/AIDS, 2016; XIII(1), page: 9-15

Genotype A

Hepatitis B (HB) vaccination is the most effective method for preventing HB virus (HBV) infection. Universal HB vaccination containing recombinant HB surface antigens (HBsAg) is recommended. Our data revealed that human monoclonal HB surface antibody (anti-HBs) from individuals inoculated with genotype C-based HB vaccine induced cross-protection against HBV genotype A infection. An in vitro infection model demonstrated anti-HBs-positive sera from individuals inoculated with genotype A- or C-based HB vaccine harbored polyclonal anti-HBs that could bind to non-vaccinated genotype HBV. However, because there were low titers of anti-HBs specific for HBsAg of non-vaccinated genotype, high anti-HBs titers would be required to prevent non-vaccinated genotype HBV infection. Clinically, the 2015 Centers for Disease Control and Prevention guidelines state that periodic monitoring of anti-HBs levels after routine HB vaccination is not needed and that booster doses of HB vaccine are not recommended. However, the American Red Cross suggests that HB-vaccine-induced immune memory might be limited; although HB vaccination can prevent clinical liver injury (hepatitis), subclinical HBV infections of non-vaccinated genotypes resulting in detectable HB core antibody could not be completely prevented. Therefore, monitoring anti-HBs levels after routine vaccination might be necessary for certain subjects in high-risk groups.

Coronavirus disease 2019 (COVID-19) is a newly emerging infectious disease, and risk communication is one of several public health emergency responses. During the pandemic, many migrant workers in Thailand experienced barriers that hamper access to health information. This study aims to explore factors related to the outcomes of health risk communication, including awareness of public health measures and preventive practices. We conducted a cross-sectional survey on migrants between January and April 2021 using cluster sampling in Phuket, Ranong, and Samut Sakhon. In the descriptive analysis, we presented the median, proportion, and ratio, while in the inferential analysis, we employed a logistic regression with robust standard errors. Although a total of 303 participants were initially included in this study, the final number was narrowed down to 288 samples due to insufficient information required for the analysis. Frequent reception of health information and primary school education showed a statistically significant association with preventive practices. Middle-aged migrant workers demonstrated a significantly lower level of preventive practices than younger migrant workers. A longer stay in Thailand was significantly related to a lower degree of awareness toward public health measures. Thus, it is necessary to promote the accessibility of health information among migrant workers in Thailand, especially those who have lived in Thailand for more than eight years, are older, and have no formal education.

Introduction: HIV epidemic has become the major problems among people with injecting drugs (PWIDs) in Nepal. The study was carried out to assess the prevalence of sexually transmitted diseases including HIV/AIDS among PWIDs. Methods: This descriptive cross-sectional survey was conducted in male PWIDs of age more than 16 years residing in Western to Far West Terai Districts of Nepal who had been injecting drugs for three months prior to the date of the survey" March-April 2017. A two-stage cluster sampling was used to recruit 300 PWIDs from seven Districts. HIV was diagnosed by using standard techniques approved by WHO. Similarly, Syphilis was tested using the "Rapid Plasma Reagin" and Hepatitis C as well as Hepatitis B was tested by using rapid test kits. Demographic data were collected by using structured questionnaire and the data obtained were entered in MS excel was transformed into the SPSS version 21 for the descriptive as well as inferential analysis. Results: Prevalence of HIV, HBV, HCV, and STI among PWIDs were 5.3%, 2.7%, 23.7%, and 2.0% respectively. Majority of the PWIDs were literate (93.7%) and their age was below 35 years. Among the married PWIDs, 32.4% had got married before the age of 19. Similarly, 53.7% of them were living with their female sexual partner, and 95.0% were living with their wife. Ninety six percent of the respondents reported to be ever involved in sexual activity, 77.1% of them initiated the sexual intercourse before the age of 20 years and 41.9% of them had more than one female sexual partner. The survey indicated that 36.3% had been injecting drugs for more than 5 years while 27.7% had been injecting for last 2-5 years and 55.0% of the respondents had injected for the first time at the age of 16-24 years. About one in 10 respondents had started injecting drugs recently. Conclusion: There is high prevalence of HIV, HCV, HBV and active syphilis among the PWIDs. Co-infection of HIV and HCV as well as Hepatitis B and C were also prevalent among PWIDs. Comprehensive education and awareness program is required to reduce the prevalence.

Hbv Vaccination

Abstract Background: Migrant workers are a susceptible population to the hepatitis b virus (HBV) and a vulnerable spot in China’s immunization procedures. There is no free HBV immunization program for migrant workers in China, so understanding migrant workers’ motivation to receive the HBV vaccine is the first step in designing effective immunization policies.Methods: A fully specified protection motivation theory (PMT) model of HBV vaccination intention among migrant workers was specified. Data were collected through a cross-sectional survey of 406 migrant workers in three migrant-dense industries in Tianjin, China. Principal component factor analysis was used to produce PMT factors and nested binary logistic regression modeling was applied to assess the associations between protection motivation and HBV vaccination intention of migrant workers.Results: The nested binary logistic regression model suggested that the severity factor and self-efficacy factor were positively related to HBV vaccination intention (OR=2.15, 95% CI: 1.25-3.71; OR=2.75, 95% CI: 1.62-4.66) while the response costs was negatively related to the HBV vaccination motivation (OR=0.50, 95% CI: 0.29-0.83). The socio-demographic variables showed that younger, married and good self-rated health status participants were statistically associated with the intention of taking the HBV vaccine. Sex, education level and income group were not significantly associated with vaccination intention. The migrant-industry variables showed that migrant location had a strong effect on migrant workers’ vaccination intention.Conclusion: Socio-demographic, migrant-industry variables and PMT factors (severity, self-efficacy and response costs) were statistically associated with migrant workers’ intention to vaccinate. Our results suggest that health policy makers should provide more information to migrants on HBV severity; inform migrant workers on where, when and how to get the HBV vaccine; tap into work organizations as a location for vaccinations; and identify migrant worker subgroups for targeted interventions.

Background: The awareness regarding Hepatitis B vaccination is necessary in the general population of Bangladesh.Objective: This study was carried out to determine the level of knowledge and the vaccination coverage of hepatitis B virus in rural population.Methodology: This cross sectional study was conducted at Bangladesh Institute of Administration and Management (BIAM), Dhaka, Bangladesh from February 2011 to April 2011. Sirajdikhan upazila of Munshiganj District was taken as a study place. All the villagers with an age group of 15 to 55 years were taken as study population. Result: A total number of 30 respondents were recruited of which male (60.0%) is predominant than female (40.0%). The mean age with SD was 23±7.256 years (range 15-53 years). Majority has told about the knowledge regarding the sequel of hepatitis B virus infection (33.3%). Almost all respondents (96.7%) are unknown about the treatment of HBV infection. Majority (76.7%) are unknown regarding taking HBV vaccination. Nobody has given positive answer in response to take vaccine. Conclusion: In conclusion information and knowledge regarding HBV infection and vaccination is very poor in the rural area of Bangladesh.DOI: http://dx.doi.org/10.3329/jcamr.v1i1.19558J Curr Adv Med Res 2014;1(1):3-7
