Hepatitis B vaccination uptake in hard-to-reach populations in London: a cross-sectional study.

ABSTRACT:

Background

In the UK, hepatitis B virus (HBV) incidence is associated with migrants from particular high-burden countries and population groups deemed 'hard-to-reach' by standard healthcare services: the homeless, people who inject drugs and ex-prisoners. Currently, there is a national targeted HBV vaccine policy for such at-risk groups, but there is limited recent evidence about 1) the levels of vaccine uptake, 2) the factors associated with incomplete vaccination, and 3) reasons for incomplete vaccination.

Methods

A questionnaire capturing social and medical history, demographic factors and information about HBV vaccination status was completed by individuals deemed hard-to-reach due to socio-structural factors that criminalise, isolate and stigmatise who consented to participate in a randomised controlled trial of a peer intervention to promote engagement with hepatitis C services. The questionnaire also captured the reasons for incomplete vaccination. Descriptive, univariable and multivariable regression analyses were undertaken.

Results

Three hundred fourty six participants completed the questionnaire. 1) 52.3% (n =?181) reported full HBV vaccination. 2) Within a multivariable model adjusting for sociodemographic variables, the presence of one or two or more socio-structural factors that are included in the national targeted vaccination policy was associated with protection against incomplete HBV vaccination (51.7% vaccine coverage in those with one factor, odds ratio 0.43 [95% confidence interval 0.20-0.92]); 70.1% coverage with two or more factors, 0.19 [0.09-0.39]; overall p-value ConclusionWithin this study of HBV vaccination uptake among hard-to-reach population groups in London, UK, we document 52.3% coverage of the full vaccine course. Critically, although participants recommended for immunisation within national guidelines had an increased likelihood of receiving a complete vaccine course, we note surprisingly low coverage in the presence of the risk factors that are national indicators for vaccination. Public health bodies should make additional efforts to improve coverage in the hard-to-reach through improved vaccine delivery systems.

Project description:Sub-Saharan Africa bears the greatest burden of cervical cancer. Human papillomavirus (HPV) vaccination programmes to prevent the disease will need to reach vulnerable girls who may not be able access health and screening services in the future. We conducted formative research on facilitators and barriers to HPV vaccination and potential acceptability of a future HPV vaccination programme amongst girls living in hard-to-reach populations in Kenya.Stakeholder interviews with Ministry of Health staff explored barriers to and support for the uptake of HPV vaccination. A situation assessment was conducted to assess community services in Maasai nomadic pastoralist communities in Kajiado County and in Korogocho informal settlement in Nairobi city, followed by focus group discussions (n=14) and semi-structured interviews (n=28) with health workers, parents, youth, and community and religious leaders. These covered marriage, knowledge of cervical cancer and HPV, factors that might inhibit or support HPV vaccine uptake and intention to accept HPV vaccine if a programme was in place.Reported challenges to an HPV vaccination programme included school absenteeism and drop-out, early age of sex and marriage, lack of parental support, population mobility and distance from services. Despite little prior knowledge of cervical cancer and HPV, communities were interested in receiving HPV vaccination. Adequate social mobilisation and school-based vaccination, supplemented by out-reach activities, were considered important facilitating factors to achieve high coverage. There was some support for a campaign approach to vaccine delivery.Given the high level of support for a vaccine against cervical cancer and the experience of reaching pastoralist and slum-dwellers for other immunizations, implementing an HPV vaccine programme should be feasible in such hard-to-reach communities. This may require additional delivery strategies in addition to the standard school-based delivery, with vaccine offered at multiple venues, potentially through a campaign approach.

Project description:Ga West Municipality in Ghana is predominantly rural with about forty-eight hard-to-reach communities. Several infectious diseases such as Buruli ulcer, tuberculosis, yaws, schistosomiasis, and malaria are prevalent in the municipality. However, the prevalence and characteristics of enteroparasites in the municipality are unknown. Therefore, this cross-sectional study determined the prevalence of enteroparasites in these hard-to-reach communities. Samples were collected from five communities, namely, Opah, Otuaplem, Dedeman, Onyansana, and Manchie. A total of 538 stool samples were collected from the community dwellers. Each sample was examined with eosin-saline wet preparation and formol-ether concentration technique. Body mass index, haemoglobin, and albumin concentrations were used to assess nutritional status. Seven different parasite species were identified in 178 community dwellers (33.1% prevalence (95% CI: 0.29–0.37)). The individual prevalence of the identified parasites was Schistosoma mansoni (13.4%), Entamoeba histolytica (7.2%), Ascaris lumbricoides (6.9%), Giardia lamblia (5.0%), hookworm (4.8%), Strongyloides stercoralis (4.8%), and Balantidium coli (1.6%). Among the 178 parasitized individuals, 68.0% were singly infected while 31.5% had dual parasitism. Significantly higher infections were associated with Onyansana dwellers (p = 0.019), participants aged 16–20 years (p = 0.006), unmarried participants (p < 0.001), those without formal education (p = 0.044), and crop farmers (p = 0.044). However, among the Akan tribe (p = 0.015), Christians (p = 0.03), and participants with higher incomes (p = 0.012), infections were found to be lower. Compared to monoparasitism, dual parasitism was significantly associated with underweight (17.8 vs. 20.3?kg/m2), anaemia (7.7 vs. 9.8?g/dL), and malnutrition (27.6 vs. 31.9?g/L of albumin concentration). These findings underscore the fact that the Ga West Municipality is heavily burdened with different species of enteroparasites. Therefore, education on personal hygiene to reduce parasitic infections must be intensified while implementing regular mass deworming exercise in the municipality.

Project description:Every year in Bangladesh, approximately 5200 mothers die (172 maternal deaths/100,000 live births) due to maternal complications. The death rate is much higher in hard-to-reach areas and underprivileged communities, such as Bangladesh's tea gardens. The women living in the tea garden areas are deprived of quality health care services due to inadequate knowledge, education, and access to health care services. Poverty and early marriage, followed by early pregnancy, are also triggering factors of maternal deaths in this community. This study explored the factors associated with maternal deaths in the underprivileged tea garden community in the Moulvibazar district of Bangladesh. It was a cross-sectional study conducted between January and March 2018. All maternal deaths reported by government health care providers in two sub-districts of Moulvibazar during 2017 were selected for community verbal autopsy using a structured questionnaire. Descriptive analysis was performed on quantitative data, and content analysis was performed on qualitative data. A total of 34 maternal deaths were reported in the two sub-districts in 2017, among which 15 deaths (44%) occurred in the tea garden catchment areas, where about 34% people live in the two upazilas. The majority of the mothers who died in the tea gardens delivered their babies at home (80%), many of whom also died at home (40%). Only 27% of women who died in the tea gardens received four or more antenatal care visits. Post-partum hemorrhage was found to be the leading cause of death (47%), followed by anemia (33%) and eclampsia (20%). There is a persistent high maternal mortality observed in the marginalized tea gardens, as compared to the general community of the Moulvibazar district, Bangladesh. The sustainable development goal (SDG) that has been set for maternal mortality rate (MMR) is 70/100,000 live births in Bangladesh. The findings of our study show that focused intervention is needed to reduce the burden of maternal deaths, which will improve the overall maternal health situation and also reach the SDG on time.

Project description:BACKGROUND:Recruiting hard-to-reach populations for health research is challenging. Web-based platforms offer one way to recruit specific samples for research purposes, but little is known about the feasibility of online recruitment and the representativeness and comparability of samples recruited through different Web-based platforms. OBJECTIVE:The objectives of this study were to determine the feasibility of recruiting a hard-to-reach population (pregnant smokers) using 4 different Web-based platforms and to compare participants recruited through each platform. METHODS:A screener and survey were distributed online through Qualtrics Panel, Soapbox Sample, Reddit, and Amazon Mechanical Turk (mTurk). Descriptive statistics were used to summarize results of each recruitment platform, including eligibility yield, quality yield, income, race, age, and gestational age. RESULTS:Of the 3847 participants screened for eligibility across all 4 Web-based platforms, 535 were eligible and 308 completed the survey. Amazon mTurk yielded the fewest completed responses (n=9), 100% (9/9) of which passed several quality metrics verifying pregnancy and smoking status. Qualtrics Panel yielded 14 completed responses, 86% (12/14) of which passed the quality screening. Soapbox Sample produced 107 completed surveys, 67% (72/107) of which were found to be quality responses. Advertising through Reddit produced the highest completion rate (n=178), but only 29.2% (52/178) of those surveys passed the quality metrics. We found significant differences in eligibility yield, quality yield, age, number of previous pregnancies, age of smoking initiation, current smokers, race, education, and income (P<.001). CONCLUSIONS:Although each platform successfully recruited pregnant smokers, results varied in quality, cost, and percentage of complete responses. Moving forward, investigators should pay careful attention to the percentage yield and cost of online recruitment platforms to maximize internal and external validity.

Project description:Background: Uganda has one of the highest maternal deaths in sub-Saharan Africa, with a mortality ratio of 336 per 100 000 live births. Early regular antenatal care (ANC) helps prevent adverse outcomes, including deaths, through prevention, identification, treatment, and/or referral of at-risk women. We explored ANC practices and associated factors among women from hard-to-reach Lake Victoria islands fishing communities in Kalangala district, Uganda. Methods: A cross-sectional survey among 486 consenting women aged 15 to 49 years, who were pregnant or had a birth or abortion in the past 6 months was conducted in 6 island fishing communities of Kalangala district, Uganda, during January to May 2018. ODK software interviewer-administered questionnaires were used to collect data on sociodemographics and ANC practices. Regression modeling using STATA version 15 was used to determine factors associated with ANC visits. Results: Women's median (range) age was 26 (15-45) years, 63% (304/486) had up to primary level education, 45% (219/486) were housewives (stay home mums), 87% (423/486) were married. ANC visits ranged from 0 to 10, with over three-fifths of women having their first visit late after 3 months of being pregnant (63%, 198/316). Women without a history of pregnancy loss (adjusted odds ratio [AOR] = 1.8, 95% CI 1.1-3.0), those not staying with their partners (AOR = 2.5, 95% CI 1.1-6.0), and those whose partners were working in fishing-related activities (AOR = 1.8, 95% CI 1.0-3.0) were likely to have started care late. Women from communities with a public health facility and those with partners working in none fishing-related activities had the highest predicted number of visits. Conclusion: Antenatal practices among these communities are characterized by late start of care. Community-led early ANC awareness interventions are needed. Targeted health policies need to consider public ANC facilities for each island for improved antenatal outcomes and maternal health.

Project description:BackgroundCaesarean section (C-section) is a major obstetric life-saving intervention for the prevention of pregnancy and childbirth related complications. Globally C-section is increasing, as well as in Bangladesh. This study identifies the prevalence of C-section and socio-economic and health care seeking related determinants of C-section among women living in hard-to-reach (HtR) areas in Bangladesh.MethodsA cross-sectional survey was conducted using a structured questionnaire between August and December 2017 at four distinct types of HtR areas of Bangladesh, namely coastal, hilly, haor (wetland), and char areas (shallow land-mass rising out of a river). Total 2,768 women of 15-49 years of age and who had delivery within one year prior to data collection were interviewed. For the analysis of determinants of C- section, the explanatory variables were maternal age, educational status of women and their husbands, women's religion, employment status and access to mobile phone, wealth index of the household, distance to the nearest health facility from the household, the number of ANC visits and presence of complications during pregnancy and the last childbirth. Logistic regression model was run among 850 women, who had facility delivery. Variables found significantly associated with the outcome (C-section) in bivariate analysis were included in the multivariable logistic model. A p-value <0.05 was considered as statistically significant in the analyses.ResultsOf the 2,768 women included in the study, 13% had C-sections. The mean (±SD) age of respondents was 25.4 (± 0.1) years. The adjusted prevalence of C-section was 13.1 times higher among women who had their delivery in private facilities than women who delivered in public facilities (Adjusted Odds Ratio, AOR: 13.1; 95% CI 8.6-19.9; p-value: <0.001). Women from haor area and coastal area had 4.7 times (AOR: 4.7; 95% CI 2.4-9.4; p value: <0.001) and 6.8 times (AOR: 6.8; 95% CI 3.6-12.8; p value: <0.001) more chance of having C-section, respectively, than women living in char area. Among women who reported complications during the last childbirth, the AOR of C-section was 3.6 times higher than those who did not report any complication (AOR: 3.6; 95% CI 2.4-5.4; p value: <0.001).ConclusionsThe study identifies that the prevalence of C-sections in four HtR areas of Bangladesh in substantially below the national average, although, the prevalence was higher in coastal areas than three other HtR regions. Both public and private health services for C-section should be made available and accessible in remote HtR areas for women with pregnancy complications. Establishment of an accreditation system for regulating private hospitals are needed to ensure rational use of the procedure.
