Fulltext Community engagement in health services research on soil-transmitted helminthiasis in Asia Pacific region: Systematic review

Naing C, Tung WS, Htet NH, Aung HH, Whittaker MA

PLOS Glob Public Health, 2023;3(3):e0001694.
PMID: 36963099 DOI: 10.1371/journal.pgph.0001694

The research question was what studies are available that have assessed community engagement in the health services research on soil-transmitted helminths? We aimed to synthesise evidence on how communities were engaged in health services research on soil-transmitted helminths in low-and-middle-income countries of the Asia-Pacific Region. We focused on this region because soil-transmitted helminths are endemic, and their burden is significant in this region. This review was conducted according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) checklist. Relevant studies were searched in health-related databases including PubMed, Ovid, and Google Scholar. We selected studies based on the selection criteria set for this review. We collected textual information about the type of health services research, the degree of community engagement, the research phases involved, and the barriers/enablers affecting community engagement in research since they are pertinent to our review question and objective. Ten studies from seven countries in the Asia Pacific region were identified for this review. Albeit with variation in the extent of their involvement, various forms of communities/groups within communities were included such as Aboriginal communities, local communities, school children and their parents, school teachers and headmasters of schools, heads of villages, religious leaders, and so on. Overall, community engagement in health services research focused on of soil-transmitted helminths was limited. Six studies (60%) had collaboration at 'developing methodology', mainly through an explanation of the objectives of the study or study process to be conducted. Seven studies (70%) revealed community participation in soil-transmitted helminths at the "data collection" stage. Only one study (10%) documented that a community leader was involved as a co-author, reflecting an involvement in 'report writing' and further 'dissemination'. Findings suggest that there were various forms of community engagement in various aspects of the health services research context. Overall, there was moderate level of participation, but there was insufficient information on the partnership between various stakeholders, which prevented in-depth analysis of the engagement. Future health services research on soil-transmitted helminth interventions needs to be carefully planned, well designed, grounded in principles of community engagement, and designed methodologically to allow in-depth participation by communities in all stages of the research.

Diagnosis of visceral leishmaniasis (VL) through the detection of its causative agents namely Leishmania donovani and L. infantum is traditionally based on immunochromatographic tests, microscopy of bone marrow, spleen aspirates, liver or lymph node and differential diagnosis. While the first process has low specificity, the later one carries the risk of fatal hemorrhage. Over the last decade, multiple Polymerase Chain Reaction (PCR) based diagnosis has been developed using blood and urine sample with a varying degree of sensitivity and specificity, an issue worth improving for precision diagnosis. Earlier, we reported a PCR-based diagnosis of L. donovani in peripheral blood using a novel set of PCR primers with absolute specificity. Using the same set of primers and PCR conditions, here we describe diagnosis of L. donovani from urine, for a non-invasive, rapid and safe diagnosis. Diagnosis of VL was carried out using urine samples collected from clinically diagnosed VL patients (n = 23) of Bangladesh in Real Time PCR. Test results were validated by comparing blood samples from the same set of patients. Sensitivity and specificity of this diagnosis was analyzed using retrospective bone marrow samples, collected earlier from confirmed VL patients (n = 19). The method showed 100% sensitivity in detecting L. donovani in urine and corresponding blood and retrospective bone marrow samples, as well as 100% specificity in control groups. A Real Time PCR-based molecular detection system using urine sample is hereafter presented what could be a, non-invasive approach for VL detection with precision and perfection.
Fulltext Community engagement in health services research on elimination of lymphatic filariasis: A systematic review

Naing C, Htet NH, Aung HH, Whittaker MA

PLOS Glob Public Health, 2023;3(1):e0001226.
PMID: 36963022 DOI: 10.1371/journal.pgph.0001226

This study aimed to contextualize the extent, nature, and quality of community engagement in health services research on eliminating lymphatic filariasis in low-and middle-income countries of Southeast Asia and Pacific Region. We performed a systematic review, and the results were reported according to the PRISMA-S checklist. Relevant studies were searched in health-related electronic databases, and selected according to the inclusion criteria. Sixteen studies with various study designs were identified. The majority (68%) were conducted in India. Lay people, community leaders, and volunteers were the most common groups of community members (12/16,75%). Overall, the majority (13/16, 81%) were at the 'moderate level' of engagement in research context mainly by 'collaboration' in 'developing methodology' 'collaboration' in data collection and 'collaboration' for 'dissemination of findings. The common barriers to the community engagement were lack of involvement of participating bodies and technology-related issues. In conclusion, the insufficient description of the community engagement process in the studies limits a deeper understanding and analysis of the issue. Future well-designed prospective studies with attention to the description of mechanisms of engagement, facilitating the whole process and reporting the community level outcome are recommended.
Fulltext Differences and agreement between two portable hand-held spirometers across diverse community-based populations in the Prospective Urban Rural Epidemiology (PURE) study

Duong M, Rangarajan S, Zaman M, Nasir NM, Seron P, Yeates K, et al.

PMID: 36962310 DOI: 10.1371/journal.pgph.0000141

INTRODUCTION: Portable spirometers are commonly used in longitudinal epidemiological studies to measure and track the forced expiratory volume in first second (FEV1) and forced vital capacity (FVC). During the course of the study, it may be necessary to replace spirometers with a different model. This raise questions regarding the comparability of measurements from different devices. We examined the correlation, mean differences and agreement between two different spirometers, across diverse populations and different participant characteristics.
METHODS: From June 2015 to Jan 2018, a total of 4,603 adults were enrolled from 628 communities in 18 countries and 7 regions of the world. Each participant performed concurrent measurements from the MicroGP and EasyOne spirometer. Measurements were compared by the intra-class correlation coefficient (ICC) and Bland-Altman method.
RESULTS: Approximately 65% of the participants achieved clinically acceptable quality measurements. Overall correlations between paired FEV1 (ICC 0.88 [95% CI 0.87, 0.88]) and FVC (ICC 0.84 [0.83, 0.85]) were high. Mean differences between paired FEV1 (-0.038 L [-0.053, -0.023]) and FVC (0.033 L [0.012, 0.054]) were small. The 95% limits of agreement were wide but unbiased (FEV1 984, -1060; FVC 1460, -1394). Similar findings were observed across regions. The source of variation between spirometers was mainly at the participant level. Older age, higher body mass index, tobacco smoking and known COPD/asthma did not adversely impact on the inter-device variability. Furthermore, there were small and acceptable mean differences between paired FEV1 and FVC z-scores using the Global Lung Initiative normative values, suggesting minimal impact on lung function interpretation.
CONCLUSIONS: In this multicenter, diverse community-based cohort study, measurements from two portable spirometers provided good correlation, small and unbiased differences between measurements. These data support their interchangeable use across diverse populations to provide accurate trends in serial lung function measurements in epidemiological studies.

With the emergence of the highly transmissible Omicron variant, large-scale vaccination coverage is crucial to the national and global pandemic response, especially in populous Southeast Asian countries such as the Philippines and Malaysia where new information is often received digitally. The main aims of this research were to determine levels of hesitancy and confidence in COVID-19 vaccines among general adults in the Philippines and Malaysia, and to identify individual, behavioural, or environmental predictors significantly associated with these outcomes. Data from an internet-based cross-sectional survey of 2558 participants from the Philippines (N = 1002) and Malaysia (N = 1556) were analysed. Results showed that Filipino (56.6%) participants exhibited higher COVID-19 hesitancy than Malaysians (22.9%; p < 0.001). However, there were no significant differences in ratings of confidence between Filipino (45.9%) and Malaysian (49.2%) participants (p = 0.105). Predictors associated with vaccine hesitancy among Filipino participants included women (OR, 1.50, 95% CI, 1.03-1.83; p = 0.030) and rural dwellers (OR, 1.44, 95% CI, 1.07-1.94; p = 0.016). Among Malaysian participants, vaccine hesitancy was associated with women (OR, 1.50, 95% CI, 1.14-1.99; p = 0.004), social media use (OR, 11.76, 95% CI, 5.71-24.19; p < 0.001), and online information-seeking behaviours (OR, 2.48, 95% CI, 1.72-3.58; p < 0.001). Predictors associated with vaccine confidence among Filipino participants included subjective social status (OR, 1.13, 95% CI, 1.54-1.22; p < 0.001), whereas vaccine confidence among Malaysian participants was associated with higher education (OR, 1.30, 95% CI, 1.03-1.66; p < 0.028) and negatively associated with rural dwellers (OR, 0.64, 95% CI, 0.47-0.87; p = 0.005) and online information-seeking behaviours (OR, 0.42, 95% CI, 0.31-0.57; p < 0.001). Efforts should focus on creating effective interventions to decrease vaccination hesitancy, increase confidence, and bolster the uptake of COVID-19 vaccination, particularly in light of the Dengvaxia crisis in the Philippines.

The Drug Dependency Treatment and Research Unit (DDTRU) in Myanmar established opioid substitution with methadone in 2006. Reducing HIV transmission could be affected by eliminating the unsafe needle sharing among injecting drug uses and treatment with opioid substitution. The quality of life (QOL) among the clients retained in the methadone program is important for their personal development and is an indication of the treatment efficacy. This study evaluated factors associated with the QOL of methadone patients to ensure efficient service delivery. It also identified how patients' characteristics had differed QOL scores of respondents. This cross-sectional study was conducted in five cities with stratified random sampling. The study assessed the QOL of methadone patients in Myanmar. The study recruited 210 respondents to answer structured questionnaires for their quality of life: WHOQOL-BREF questionnaires and urine sample collection for methadone and illicit drug use. Survey responses on the QOL were transformed into 100-scale ratings, and higher QOL scores reflect better QOL. The average score of total QOL was 60.82%; precisely 60.09% in the physical domain, 63.11% in the psychological domain, 59.87% in the social relation domain, 60.41% in the environmental domain respectively. Respondents who reported illicit drug use had lower QOL scores. Statistically significant association of the QOL category of the methadone patients was identified with frequent methadone treatment episodes, the infection status of HIV, current treatment on antiretroviral therapy (ART), tuberculosis (TB) treatment history, sexually transmitted infections (STI) history in their lifetime, current work status as peer, Addiction Severity Index (ASI) for drug use, satisfaction with current marital status, satisfaction with current leisure status, history of psychological abuse within 30 days, heroin injection within 30 days, frequency of injection, and reported use of barbiturates (p<0.05). Addressing these factors will improve the treatment service intervention and the quality of life among methadone patients.
Fulltext Too many yet too few caesarean section deliveries in Bangladesh: Evidence from Bangladesh Demographic and Health Surveys data

PMID: 36962249 DOI: 10.1371/journal.pgph.0000091

Caesarean section (CS) use is rising rapidly in Bangladesh, though lack of CS use remains common among disadvantage women. This increases risks of long-term obstetric complications as well as maternal and child deaths among disadvantage women. We aimed to determine the interaction effects of women's disadvantage characteristics on CS use in Bangladesh. For this we have analysed a total of 27,093 women's data extracted from five rounds of Bangladesh Demographic and Health Survey conducted during 2004 and 2017/18. The outcome variable was CS use, coded as use (1) and non-use (0). The major exposure variables were individual level, household level, and community level characteristics. Multilevel logistic regression model was used to determine association of CS use with socio-demographic characteristics and the interactions of three variables: working status, wealth quintile, and place of residence. We found a 751% increase of CS use over the last 13 years-from 3.88% in 2004 to 33% in 2017/18. Nearly, 80% of the total CS operation occurred in the private health facilities followed by the government health facilities (15%). Women living in rural areas with no engagement in formal income generating activities showed a 11% (OR, 0.89, 95% CI, 0.71-0.99) lower use of CS in 2004. This association was further strengthened over time, and a 51% (OR, 0.49, 0.03-0.65) lower in CS use was reported in 2017/18. Similarly, around 12%-83% lower likelihoods of CS use were found among rural poor and poorer women. These indicate Bangladesh is facing a double burden of CS use, that is a group of women with improved socio-economic condition are using this life saving procedure without medical necessity while their counterpart of disadvantage characteristics could not access the service. Improved monitoring from the government along with support to use CS services for the disadvantage groups on necessity are important.

INTRODUCTION: The COVID-19 pandemic has become the greatest challenge of the new millennium. Most healthcare workers (HCWs) experienced unprecedented levels of workload since the pandemic. This study aims to identify the prevalence and factors of depression, anxiety and stress among HCWs in Malaysian healthcare facilities in the midst of the pandemic due to the SARs-CoV-2.
METHODS: An emergency response programme on mental health was conducted from June to September 2020. A standardized data collection form was distributed among the HCWs in the government hospital in Klang Valley. The form contained basic demographic information and the self-reported Malay version of the Depression, Anxiety and Stress scale (BM DASS-21).
RESULTS: Of the1,300 staff who attended the Mental Health and Psychosocial Support in Covid-19 (MHPSS COVID-19) programme, 996 staff (21.6% male, 78.4% female) completed the online survey (response rate: 76.6%). Result showed that staff aged above 40 years old were almost two times more likely to have anxiety (AOR = 1.632; 95% CI = 1.141-2.334, p:0.007) and depression (AOR = 1.637; 95% CI = 1.1.06-2.423, p:0.014) as compared to staff who were less than 40 years old. Those who had direct involvement with COVID-19 patients were likely to suffer stress (AOR = 0.596; 95% CI = 0.418-0.849, p:0.004), anxiety (AOR = 0.706; 95% Ci = 0.503-0.990, p:0.044) and depression (AOR = 0.630; 95% Ci = 0.427-0.928, p:0.019). HCWs with stress (AOR = 0.638; 95% CI of 0.476-0.856, p = 0.003), anxiety (AOR = 0.720; 95% CI 0.542-0.958, p = 0.024) and depression (AOR = 0.657; 95% CI 0.480-0.901, p = 0.009) showed less confidence to treat critically ill patients and need psychological help during outbreak.
CONCLUSION: This study showed the importance of psychosocial support to reduce psychological distress among HCWs when working or coping during the COVID-19 pandemic or outbreak.
Fulltext National and subnational burden of under-5, infant, and neonatal mortality in Ethiopia, 1990-2019: Findings from the Global Burden of Disease Study 2019

The under-5 mortality rate is a commonly used indicator of population health and socioeconomic status worldwide. However, as in most low- and middle-income countries settings, deaths among children under-5 and in any age group in Ethiopia remain underreported and fragmented. We aimed to systematically estimate neonatal, infant, and under-5 mortality trends, identify underlying causes, and make subnational (regional and chartered cities) comparisons between 1990 and 2019. We used the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD 2019) to estimate three key under-5 mortality indicators-the probability of death between the date of birth and 28 days (neonatal mortality rate, NMR), the date of birth and 1 year (infant mortality rate, IMR), and the date of birth and 5 years (under-5 mortality rate, U5MR). The causes of death by age groups, sex, and year were estimated using Cause of Death Ensemble modelling (CODEm). Specifically, this involved a multi-stage process that includes a non-linear mixed-effects model, source bias correction, spatiotemporal smoothing, and a Gaussian process regression to synthesise mortality estimates by age, sex, location, and year. In 2019, an estimated 190,173 (95% uncertainty interval 149,789-242,575) under-5 deaths occurred in Ethiopia. Nearly three-quarters (74%) of under-5 deaths in 2019 were within the first year of life, and over half (52%) in the first 28 days. The overall U5MR, IMR, and NMR in the country were estimated to be 52.4 (44.7-62.4), 41.5 (35.2-50.0), and 26.6 (22.6-31.5) deaths per 1000 livebirths, respectively, with substantial variations between administrative regions. Over three-quarters of under-5 deaths in 2019 were due to five leading causes, namely neonatal disorders (40.7%), diarrhoeal diseases (13.2%), lower respiratory infections (10.3%), congenital birth defects (7.0%), and malaria (6.0%). During the same period, neonatal disorders alone accounted for about 76.4% (70.2-79.6) of neonatal and 54.7% (51.9-57.2) of infant deaths in Ethiopia. While all regional states in Ethiopia have experienced a decline in under-5, infant, and neonatal mortality rates in the past three decades, the rate of change was not large enough to meet the targets of the Sustainable Development Goals (SDGs). Inter-regional disparities in under 5 mortality also remain significant, with the biggest differences being in the neonatal period. A concerted effort is required to improve neonatal survival and lessen regional disparity, which may require strengthening essential obstetric and neonatal care services, among others. Our study also highlights the urgent need for primary studies to improve the accuracy of regional estimates in Ethiopia, particularly in pastoralist regions.
Fulltext The effects of COVID-19 lockdown measures on health and healthcare services in Uganda

Many countries across the world instituted lockdowns as a measure to prevent the spread of COVID-19. However, these lockdowns had consequences on health systems. This study explored effects of the COVID-19 lockdown measures on health and healthcare services in Uganda. The qualitative study employed focus group discussions (FGDs), household interviews, and key informant interviews (KIIs) in both an urban (Kampala district) and rural (Wakiso district) setting in central Uganda. Fourteen FGDs were conducted among community members, local leaders, community health workers, and health practitioners. Interviews were conducted among 40 households, while 31 KIIs were held among various stakeholders including policy makers, non-governmental organisations, and the private sector. Data was analysed by thematic analysis with the support of NVivo 2020 (QSR International). Findings from the study are presented under four themes: maternal and reproductive health; child health; chronic disease services; and mental health. Maternal and reproductive health services were negatively affected by the lockdown measures which resulted in reduced utilisation of antenatal, postnatal and family planning services. These effects were mainly due to travel restrictions including curfew, and fear of contracting COVID-19. The effects on child health included reduced utilisation of services which was a result of difficulties faced in accessing health facilities because of the travel restrictions. Patients with chronic conditions could not access health facilities for their routine visits particularly due to suspension of public transport. Depression, stress and anxiety were common due to social isolation from relatives and friends, loss of jobs, and fear of law enforcement personnel. There was also increased anxiety among health workers due to fear of contracting COVID-19. The COVID-19 lockdown measures negatively affected health, and reduced access to maternal, reproductive and child health services. Future interventions in pandemic response should ensure that their effects on health and access to health services are minimised.
Fulltext Plasma CXCL8 and MCP-1 as surrogate plasma biomarkers of latent tuberculosis infection among household contacts-A cross-sectional study

PMID: 37992019 DOI: 10.1371/journal.pgph.0002327

Early detection of latent tuberculosis infection (LTBI) is critical to TB elimination in the current WHO vision of End Tuberculosis Strategy. The study investigates whether detecting plasma cytokines could aid in diagnosing LTBI across household contacts (HHCs) positive for IGRA, HHCs negative for IGRA, and healthy controls. The plasma cytokines were measured using a commercial Bio-Plex Pro Human Cytokine 17-plex assay. Increased plasma CXCL8 and decreased MCP-1, TNF-α, and IFN-γ were associated with LTBI. Regression analysis showed that a combination of CXCL8 and MCP-1 increased the risk of LTBI among HHCs to 14-fold. Our study suggests that CXCL-8 and MCP-1 could serve as the surrogate biomarkers of LTBI, particularly in resource-limited settings. Further laboratory investigations are warranted before extrapolating CXCL8 and MCP-1 for their usefulness as surrogate biomarkers of LTBI in resource-limited settings.
Fulltext The incidence, and spatial trends of cholera in Sabah over 15 years: Repeated outbreaks in coastal areas

Vibrio cholerae remains a notable public health challenge across Malaysia. Although the Malaysian state of Sabah is considered a cholera-affected area, gaps remain in understanding the epidemiological trends and spatial distribution of outbreaks. Therefore, to determine longitudinal and spatial trends in cholera cases data were obtained from the Sabah State Health Department for all notified cases of cholera between 2005-2020. A cholera outbreak is defined as one or more confirmed cases in a single locality with the evidence of local transmission. All records were geolocated to village level. Satellite-derived data and generalised linearized models were used to assess potential risk factors, including population density, elevation, and distance to the sea. Spatiotemporal clustering of reported cholera cases and zones of increased cholera risk were evaluated using the tau statistic (τ) at 550m, 5km and 10km distances. Over a 15-year period between 2005-2020, 2865 cholera cases were recorded in Sabah, with a mean incidence rate of 5.6 cases per 100,000 (95% CI: 3.4-7.9). From 2015-2020, 705 symptomatic cases and 727 asymptomatic cases were reported. Symptomatic cases primarily occurred in local Malaysian populations (62.6%, 441/705) and in children and adolescents under 15-years old (49.4%, 348/705). On average, cases were reported in areas with low population density (19.45 persons/km2), low elevations (19.45m) and near coastal areas. Spatiotemporal clustering of cholera cases was identified up to 3.5km, with increased village-level cholera risk within 500m and 5 days of initial case presentation to a health facility (Risk Ratio = 9.7, 95% CI: 7.5-12.4). Cholera incidence has high spatial and temporal heterogeneity within Sabah, with some districts experiencing repeated outbreaks. Cholera cases clustered across space and time, with village-level risk of cholera highest within 5 days and within close proximity to primary case villages, suggesting local transmission.
Usability and acceptability of oral fluid- and blood-based hepatitis C virus self-testing among the general population and men who have sex with men in Malaysia

Hepatitis C self-testing (HCVST) is emerging as an additional strategy that could help to expand access to HCV testing. We conducted a study to assess the usability and acceptability of two types of HCVST, oral fluid- and blood-based, among the general population and men who have sex with men (MSM) in Malaysia. An observational study was conducted in three primary care centres in Malaysia. Participants who were layman users performed the oral fluid- and blood-based HCVST sequentially. Usability was assessed by calculating the rate of errors observed, the rate of difficulties faced by participants as well as inter-reader (self-test interpreted by self-tester vs interpreted by trained user) and inter-operator concordances (self-test vs test performed by trained user). The acceptability of HCV self-testing was assessed using an interviewer-administered semi-structured questionnaire. Participants were also required to read contrived test results which included "positive", "negative", and "invalid". There was a total of 200 participants (100 general population, 100 MSM; mean age 33.6 ± 14.0 years). We found a high acceptability of oral fluid- and blood-based HCVST across both general population and MSM. User errors, related to timekeeping and reading within stipulated time, were common. However, the majority of the participants were still able to obtain and interpret results correctly, including that of contrived results, although there was substantial difficulty interpreting weak positive results. The high acceptability of HCVST among the participants did not appreciably change after they had experienced both tests, with 97.0% of all participants indicating they would be willing to use HCVST again and 98.5% of them indicating they would recommend it to people they knew. There was no significant difference between the general population and MSM in these aspects. Our study demonstrates that both oral fluid- and blood-based HCVST are highly acceptable among both the general population and MSM. Both populations also showed comparable ability to conduct the tests and interpret the results. Overall, this study suggests that HCVST could be introduced as an addition to existing HCV testing services in Malaysia. Further studies are needed to establish the optimal positioning of self-testing alongside facility-based testing to expand access to HCV diagnosis in the country.

COVID-19 vaccination rates for children globally are relatively low. This study aimed to investigate parental vaccine hesitancy and parents' acceptance of a COVID-19 for their children for their children in the United States, China, Taiwan, India, Indonesia, and Malaysia.We analyzed data from an opt-in, internet-based cross-sectional study (n = 23,940). Parents were asked about their acceptance of a COVID-19 vaccine for their children, and if they would accept the vaccine with different risk and effectiveness profiles for themselves. Poisson regression was used to generate prevalence ratios (PR) of the relationship between vaccine acceptance for a child and vaccine profile, by country and waves and overall. Between August 2020 and June 2021, COVID-19 vaccine acceptance for children decreased in the United States (89% to 72%) and Taiwan (79% to 71%), increased in India (91% to 96%) and Malaysia (81% to 91%), and was stable in Indonesia (86%) and China (at 87%-90%). Vaccine risk and effectiveness profiles did not consistently affect parent's acceptance of a COVID-19 vaccine for their children. Instead, being not hesitant was a large driver of vaccine acceptance (PR: 1.24, 95% CI: 1.14, 1.36). Adolescent COVID-19 vaccination have already been established in many high and middle-income countries, but our study suggests that there is a movement of vaccine hesitancy which could impede the success of future pediatric and adolescent COVID-19 vaccination programs.

The COVID-19 pandemic presents an opportunity to assess the relationship between personal experiences and vaccine decision-making. The aim of this study was to examine the associations between experiences with COVID-19 and COVID-19 vaccination status. We administered 28 repeated cross-sectional, online surveys between June 2020 and June 2021 in the US and Asia. The main exposure was media showing COVID-19 cases, and we distinguished those with no such experience, those seeing a not severe case of disease, and those seeing a severe case of disease. Logistic regression models estimated the association between experience and acceptance of a hypothetical COVID-19 vaccine (pre-rollout) or actual vaccination (post-rollout). We explored perceived susceptibility as a potential mediator. Intent to vaccinate was lowest in the US and Taiwan, and highest in India, Indonesia, and China. Across all countries, seeing a severe case of COVID-19 in the media was associated with 1.72 times higher odds of vaccination intent in 2020 (95% CI: 1.46, 2.02) and 2.13 times higher odds of vaccination in 2021 (95% CI: 1.70, 2.67), compared to those not seeing a case or a less severe case. Perceived susceptibility was estimated to mediate 25% of the relationship with hypothetical vaccination (95% CI: 18%, 31%, P<0.0001), and 16% of the relationship with actual vaccination 16% (95% CI: 12%, 19%, P<0.0001). Seriousness of experiences could relate to intention to vaccinate against COVID-19. Media exposures are a modifiable experience, and this study highlights how this experience can relate to risk perceptions and eventual vaccination, across a variety of countries where the course of the pandemic differed.
Fulltext Towards a Feminist Global Health Policy: Power, intersectionality, and transformation

In the realm of global health policy, the intricacies of power dynamics and intersectionality have become increasingly evident. Structurally embedded power hierarchies constitute a significant concern in achieving health for all and demand transformational change. Adopting intersectional feminist approaches potentially mitigates health inequities through more inclusive and responsive health policies. While feminist approaches to foreign and development policies are receiving increasing attention, they are not accorded the importance they deserve in global health policy. This article presents a framework for a Feminist Global Health Policy (FGHP), outlines the objectives and underlying principles and identifies the actors responsible for its meaningful implementation. Recognising that power hierarchies and societal contexts inherently shape research, the proposed framework was developed via a participatory research approach that aligns with feminist principles. Three independent online focus groups were conducted between August and September 2022 with 11 participants affiliated to the global-academic or local-activist level and covering all WHO regions. The qualitative content analysis revealed that a FGHP must be centred on considerations of intersectionality, power and knowledge paradigms to present meaningful alternatives to the current structures. By balancing guiding principles with sensitivity for context-specific adaptations, the framework is designed to be applicable locally and globally, whilst its adoption is intended to advance health equity and reproductive justice, with communities and policymakers identified as the main actors. This study underscores the importance of dismantling power structures by fostering intersectional and participatory approaches for a more equitable global health landscape. The FGHP framework is intended to initiate debate among global health practitioners, policymakers, researchers and communities. Whilst an undeniably intricate and time-consuming process, continuous and collaborative work towards health equity is imperative to translate this vision into practice.
Decolonising global health research: Shifting power for transformative change

Recent debates on decolonizing global health have spurred interest in addressing the power asymmetries and knowledge hierarchies that sustain colonial ideas and relationships in global health research. This paper applies three intersecting dimensions of colonialism (colonialism within global health; colonisation of global health; and colonialism through global health) to develop a broader and more structural understanding of the policies and actions needed to decolonise global health research. It argues that existing guidelines and checklists designed to make global health research more equitable do not adequately address the underlying power asymmetries and biases that prevail across the global health research ecosystem. Beyond encouraging fairer partnerships within individual research projects, this paper calls for more emphasis on shifting the balance of decision-making power, redistributing resources, and holding research funders and other power-holders accountable to the places and peoples involved in and impacted by global health research.
