A tuberculosis elimination-focused geospatial approach to optimising access to diagnostic GeneXpert machines in Fiji.

OBJECTIVES: Fiji could be the first country to eliminate tuberculosis. To inform this strategy, we aimed to identify how many GeneXpert® machines are required to enable over 90% of Fijians to be within one-hour easy access. METHODS: We used Geographic Information System (Quantum GIS; QGIS), OpenStreetMap and population data (Kontur) to map possible facilities in relation to QGIS generated 60-min drive-time isochrones, with correction for missing road data. For outer islands, we calculated a distance to nearest hub operation. RESULTS: The solution comprised 24 GeneXpert® machines, allocating 7 GeneXpert® to Viti Levu, 6 GeneXpert® to Vanua Levu and 11 to other islands. This resulted in 827,810 people, 93.6% of Fiji's population, being within 1 h of a machine. Twenty-one thousand four hundred seventy-nine people on outer islands were an average of 43 km by water from the nearest facility. CONCLUSIONS: We conclude that over 90% of Fijians could be within an hour of a GeneXpert® machine with placement of 24 machines.

Understanding Fijian health system challenges in the prevention of mother-to-child transmission of HIV services in the three tertiary hospitals in Fiji.

Mother-to-child transmission is the most common route of human immunodeficiency virus transmission in children, which could be prevented with proper treatment and access to care. Health system challenges can impede the effectiveness of prevention of mother-to-child transmission (PMTCT) programmes. We aim to understand the health system challenges to the provision of PMTCT services for pregnant women in three tertiary hospitals in Fiji. Data were collected using in-depth interviews in the three tertiary hospitals and associated health clinics in Fiji between April-May 2013 and February-March 2014. Ethical approvals were obtained. A total of 58 healthcare providers were interviewed including doctors (n = 12), midwives (n = 19), nurses (n = 14), laboratory technicians (n = 5) and counsellors (n = 8). The data were analysed using thematic analysis. We found that the healthcare workers faced a wide range of health system challenges including institutional and human resource challenges. Staff shortage, limited PMTCT training and shortage of supplies were barriers to the quality of PMTCT services. Our findings would be useful in developing strategies to overcome barriers as it would be imperative in improving the quality of PMTCT service provision in Fiji and other similar settings.

Extreme mortality during a historical measles outbreak on Rotuma is consistent with measles immunosuppression.

Until the early twentieth century, populations on many Pacific Islands had never experienced measles. As travel to the Pacific Islands by Europeans became more common, the arrival of measles and other pathogens had devastating consequences. In 1911, Rotuma in Fiji was hit by a measles epidemic, which killed 13% of the island population. Detailed records show two mortality peaks, with individuals reported as dying solely from measles in the first and from measles and diarrhoea in the second. Measles is known to disrupt immune system function. Here, we investigate whether the pattern of mortality on Rotuma in 1911 was a consequence of the immunosuppressive effects of measles. We use a compartmental model to simulate measles infection and immunosuppression. Whilst immunosuppressed, we assume that individuals are vulnerable to dysfunctional reactions triggered by either (i) a newly introduced infectious agent arriving at the same time as measles or (ii) microbes already present in the population in a pre-existing equilibrium state. We show that both forms of the immunosuppression model provide a plausible fit to the data and that the inclusion of immunosuppression in the model leads to more realistic estimates of measles epidemiological parameters than when immunosuppression is not included.

Clinical practice guidelines: Their utility, dissemination and monitoring at Colonial War Memorial Hospital: A mixed methods study from Fiji.

BACKGROUND: Clinical practice guidelines (CPGs) improve patient care by standardising medical practice. However, little is known about their applicability in low-resource settings. Since 2010, Fiji has introduced guidelines to increase the application of evidence-based practice. AIMS: We describe the dissemination, utility and monitoring of guideline implementation in Fiji, a low-resource setting in the Pacific. METHODS: A mixed-methods design included a survey and focus groups. All 178 doctors in five departments at Fiji's largest tertiary hospital were invited to participate. Subsequently, two focus group interviews explored clinicians' perspectives in more detail. Analysis included data description, multi-variable logistic, multinomial regression and manifest content analyses. RESULTS: The response rate was 74%. Most doctors agreed that CPGs were good for patient management (100%), doctors continuing medical education (CME) (96%), patient education (73%), supported by systematic reviews (91%) and consistent with existing norms/values (83%). Ninety-five per cent stated that CPGs increased the quality of care, and 80% stated that CPGs increased physician satisfaction. Approximately two-thirds stated that CPGs decreased medical-legal problems (63%) and malpractice suits (68%). Sixty to 90% of doctors disagreed that CPGs were oversimplified/cookbook medicine (60%), too rigid to apply individually (65%), challenged physician autonomy (60%) or were ambiguous/unclear (86%) or not practical (89%). The preferred method of dissemination was CME, and quick reference guides were best for implementation. No formal CPG monitoring existed in any department. CONCLUSION: Most physicians found CPGs to be valuable for improving the consistency of care. In low-resource settings, dissemination of guidelines should be paired with CME to improve their uptake. Increased monitoring of guideline use appears necessary.

Strengthening rural community water safety planning in Pacific Island countries: evidence and lessons from Solomon Islands, Vanuatu, and Fiji.

Pacific Island Countries (PICs) collectively have the lowest rates of access to safely managed or basic drinking water and sanitation globally. They are also the least urbanised, have dynamic socioeconomic and increasing climate-linked challenges. Community-based water managers need to respond to variability in water availability and quality caused by a range of hazards. Water Safety Planning (WSP), a widely adopted approach to assessing water supply, offers a risk-based approach to mitigating both existing and future hazards. WSP is adaptable, and making modifications to prescribed WSP to adapt it to the local context is common practice. Within the Pacific Community Water Management Plus research project, we used formative research and co-development processes to understand existing local modifications, whether further modifications are required, and, to develop additional modifications to WSP in Fiji, Vanuatu and Solomon Islands. The types of additional local modifications we recommend reflect the unique context of PICs, including adjusting for community management of water supplies and required collective action, community governance systems, levels of social cohesion in communities, and preferred adult-learning pedagogies. Incorporating modifications that address these factors into future WSP will improve the likelihood of sustained and safe community water services in Pacific and similar contexts.

Energy, nutrient and overall healthiness of processed packaged foods in Fiji, a comparison between 2018 and 2020.

In Fiji, packaged foods are becoming increasingly available. However, it is unknown if nutrition composition of these foods has changed. This study aims to assess changes in energy, nutrient content and healthiness of packaged foods by comparing data from five major supermarkets in Fiji in 2018 and 2020. Foods were categorised into 14 groups; nutrient composition information was extracted and healthiness assessed using Health Star Rating (HSR). Descriptive statistics and a separate matched products analysis was conducted summarising differences in nutrient content and HSR. There was limited evidence of change in the nutrient content of included products however, there was a small reduction in mean saturated fat in the snack food category (-1.0 g/100 g, 95% CI -1.6 to -0.4 g/100 g). The proportion of products considered healthy based on HSR, increased in the convenience foods category (28.4%, 95% CI 8.3 to 48.5) and decreased in non-alcoholic beverages (-35.2%, 95% CI -43.6 to -26.9). The mean HSR score increased in the fruit and vegetables category (0.1 (95% CI 0.1, 0.2)) and decreased for non-alcoholic beverages (-1.1 (-1.3, -0.9)) and the sauces, dressings, spreads, and dips category (-0.3 (-0.3, -0.2)). Strengthened monitoring of the food supply is needed to improve the healthiness of foods available.

Rapid SARS-CoV-2 Seroprevalence Survey in Central and Western Divisions of Fiji, 2021.

During November-December 2021, we performed a SARS-CoV-2 seroprevalence survey in Central and Western Divisions of Fiji. A total of 539 participants 8-70 years of age were 95.5% (95% CI 93.4%-97.1%) seropositive, indicating high community levels of immunity. Seroprevalence studies can inform public health responses to emerging SARS-CoV-2 variants.

A story of vicariance? how the geology of oceanic archipelagos influenced the evolutionary history of endemic damselflies.

South Pacific islands provide an ideal study system to explore patterns of speciation, specifically examining the role of dispersal versus vicariance. Dispersal is often the suggested mechanism of diversification in the South Pacific, specifically among remote island chains. Here, we provide a phylogeny of several related genera of Coenagrionidae (Odonata: Zygoptera) from the South Pacific, based on five molecular loci, in order to examine patterns of speciation in the region. We used the endemic damselfly genera Nesobasis, Nikoulabasis, and Vanuatubasis found across both Fiji and Vanuatu. Knowledge of the geologic history of the region was used to inform our understanding of the evolution of these genera. Both archipelagos used to be part of the Vitiaz arc which spanned from the Solomon Islands to Tonga and began to break apart 10-12 Ma. Results of our divergence-time estimations and biogeographic reconstructions support that the breakup of this arc acted as a significant vicariance event in the evolution of these taxa. Specifically, it led to the extant generic diversity seen in these damselflies. We find that within the archipelago of Vanuatu, that Espiritu Santo served as an important source for dispersal to other islands with Malekula acting as a stepping stone to Efate.

The challenges in protecting public health interests in multisectoral governance in the context of small island developing states: the case of tobacco control in Fiji and Vanuatu.

BACKGROUND: The commercial determinants of health (CDoH) drive the rise of NCDs globally, and their regulation requires multisectoral governance. Despite existing recommendations to strengthen institutional structures, protecting public health interests can be challenging amidst industry interference and conflicting policy priorities, particularly in low and middle-income countries (LMICs) where the need for rapid economic development is pronounced. Small island developing states (SIDS) face even more challenges in regulating CDoH because their unique socioeconomic, political, and geographic vulnerabilities may weaken institutional conditions that could aid health sector actors in protecting health interests. This study aims to explore the institutional conditions that shape health sector actors' capability to protect public health interests in tobacco governance in Fiji and Vanuatu. METHODS: We employed a qualitative, exploratory case study design. We applied the administrative process theory to inform data collection and analysis. Seventy interviews were completed in Fiji and Vanuatu from 2018 to 2019. RESULTS: The findings show that the protection of health interests in tobacco governance were not supported by the institutional conditions in Fiji and Vanuatu. While the policy processes formally ensured a level playing field between actors, policies were often developed through informal mechanisms, and the safeguards to protect public interests from vested private interests were not implemented adequately. SIDS vulnerabilities and weak regulation of political parties contributed to the politicisation of government in both states, resulting in high-level government officials' questionable commitment to protect public health interests. The system of checks and balances usually embedded into democratic governments appeared to be muted, and policymakers had limited bureaucratic autonomy to elevate health interests in multisectoral policymaking amidst high-level government officials' frequent rotation. Finally, capacity constraints aggravated by SIDS vulnerabilities negatively impacted health sector actors' capability to analyse policy alternatives. CONCLUSIONS: Health sector actors in Fiji and Vanuatu were not supported by institutional conditions that could help them protect public health interests in multisectoral governance to regulate CDoH originating from the tobacco industry. Institutional conditions in these states were shaped by SIDS vulnerabilities but could be improved by targeted capacity building, governance and political system strengthening.

Food insecurity, COVID-19 and diets in Fiji - a cross-sectional survey of over 500 adults.

INTRODUCTION: Food insecurity is associated with inadequate nutrition and increased rates of chronic disease. The primary aim of this study was to assess self-reported food insecurity and the perceived impact of COVID-19 on food security, in two regional districts of Central Fiji, as part of a broader program of work on strengthening and monitoring food policy interventions. The secondary aim was to explore the relationship between food insecurity and salt, sugar and fruit and vegetable intake. METHODS: Seven hundred adults were randomly sampled from the Deuba and Waidamudamu districts of Viti Levu, Fiji. Interview administered surveys were conducted by trained research assistants with data collected electronically. Information was collected on demographics and health status, food security, the perceived impact of COVID-19 on food security, and dietary intake. Food insecurity was assessed using nine questions adapted from Fiji's 2014/5 national nutrition survey, measuring markers of food insecurity over the last 12 months. Additional questions were added to assess the perceived effect of COVID-19 on responses. To address the secondary aim, interview administered 24-hour diet recalls were conducted using Intake24 (a computerised dietary recall system) allowing the calculation of salt, sugar and fruit and vegetable intakes for each person. Weighted linear regression models were used to determine the relationship between food insecurity and salt, sugar and fruit and vegetable intake. RESULTS: 534 people participated in the survey (response rate 76%, 50.4% female, mean age 42 years). 75% (75.3%, 95% CI, 71.4 to 78.8%) of people reported experiencing food insecurity in the 12 months prior to the survey. Around one fifth of people reported running out of foods (16.8%, 13.9 to 20.2%), having to skip meals (19.3%, 16.2 to 22.9%), limiting variety of foods (19.0%, 15.9 to 22.5%), or feeling stressed due to lack of ability to meet food needs (19.5%, 16.4 to 23.0%). 67% (66.9%, 62.9 to 70.7%) reported becoming more food insecure and changing what they ate due to COVID-19. However, people also reported positive changes such as making a home garden (67.8%, 63.7 to 71.6%), growing fruit and vegetables (59.5%, 55.6 to 63.8%), or trying to eat healthier (14.7%, 12.0 to 18.0%). There were no significant associations between food insecurity and intakes of salt, sugar or fruit and vegetables. CONCLUSION: Participants reported high levels of food insecurity, exceeding recommendations for salt and sugar intake and not meeting fruit and vegetable recommendations, and becoming more food insecure due to COVID-19. Most participants reported making home gardens and/or growing fruit and vegetables in response to the pandemic. There is an opportunity for these activities to be fostered in addressing food insecurity in Fiji, with likely relevance to the Pacific region and other Small Island Developing States who face similar food insecurity challenges.

A novel automated protocol for ice crystal segmentation analysis using Cellpose and Fiji.

Accurate measurement of ice crystal size is an essential step in quantitative ice recrystallization inhibition (IRI) analysis using the sucrose sandwiching assay (SSA) and splat assay (SA). Here, we introduce a novel method of measuring ice crystal size and shape using Fiji and Cellpose, an anatomical segmentation algorithm, to address the time-consuming and limited number of ice particle determination associated with the mean largest grain size measurement. This new automated approach, displaying rapid segmentation of ∼70 s per image, measures every ice crystal in an image field of view, consequently reducing bias introduced by subjectively selecting the largest crystals in an image. Consistent in determining a diverse set of crystal sizes and shapes, this method allows for the evaluation of ice crystals using Feret's diameter, a parameter that better accounts for irregular particle shape. This method provides new outputs such as standard deviation, particle size distributions of a population of ice crystals, and circularity to characterize and further provide insight into an analyte's IRI ability. Applicable to the SSA, the "shape descriptor" measurement can be used to quantify ice binding. This work presents a novel and accurate approach for ice crystal quantitative analysis.

Predictors of Knowledge, Attitude, and Practice (KAP) Towards Family Planning (FP) Among Pregnant Women in Fiji.

OBJECTIVE: This study aimed to determine the predictors of Knowledge, Attitude and Practice (KAP) towards Family Planning (FP) among pregnant Fijian women. METHODS: A cross-sectional study was conducted over two months in 2019 with adult pregnant women attending the Antenatal Clinic (ANC) at Ba Mission Hospital (BMH), Fiji. Data was collected using a self-administrated questionnaire. Statistical analysis included correlation tests and regression analysis in determining predictors of KAP. RESULTS: 240 pregnant women participated in this study with a mean age of 26.02 (± SD = 4.13). The results showed a moderate level of knowledge (mean 14.95, SD ± 3.15), positive attitude (mean 20.56, SD ± 5.68), and good practice (mean 4.97, SD ± 1.73). Linear regression identified that women with more than seven children had a knowledge score of 3.65, lower than null parity (t value = -2.577, p = 0.011). Women aged 20 to 24 had a 6.47 lower attitude score than women aged 18 to 19 (t value = -2.142, p = 0.033). Women in defacto relationships had a 2.12 lower attitude score compared to the married category (t value = -2.128, p = 0.034). Fijian women of Indian descent had a 1.98 lower attitude score than the I Taukei women (t value = -2.639, p = 0.009). Women aged 30-34 had 2.41 lower practice scores than those aged 18-19 (t value = -2.462, p = 0.015). CONCLUSION: This study found a medium knowledge of FP among pregnant women. These findings support a recommendation for further research to implement effective strategies.

Cultural values influencing iTaukei women's discussion of family planning in the home.

Pacific Sexual and reproductive health is influenced by cultural taboos and sensitivities. Although Pacific values are integral to family planning, open communication in the home is often difficult in the face of changing socio-cultural norms. This study explores the experiences of iTaukei Pacific women living in Fiji and Aotearoa New Zealand, and their discussion of family planning within the family setting. The study utilises talanoa methodology to understand women's realities and their navigation through shifting sexual and reproductive norms in both countries. The study found that although family may be seen as a place of 'truth' in which appropriate, culturally sensitive family planning communication should be available, this was challenged by cultural taboos or tabu which were persistent in family planning discussions. The study calls for greater reliance on holistic approaches to Pacific family planning perspectives and a greater examination of va or the spaces within which Pacific women's experiences are negotiated and informed.

Protecting children from unhealthy food marketing: a comparative policy analysis in Australia, Fiji and Thailand.

Restrictions on marketing of unhealthy foods and beverages to children is a globally recommended policy measure to improve diets and health. The aim of the analysis was to identify opportunities to enable policy learning and shift beliefs of relevant actors, to engender policy progress on restrictions on marketing of unhealthy foods to children. We drew on the Advocacy Coalition Framework to thematically analyse data from qualitative policy interviews conducted Australia (n = 24), Fiji (n = 10) and Thailand (n = 20). In all three countries two clear and opposing advocacy coalitions were evident within the policy subsystem related to regulation of unhealthy food marketing, which we termed the 'strengthen regulation' and 'minimal/self regulation' coalitions. Contributors to policy stasis on this issue were identified as tensions between public health and economic objectives of government, and limited formal and informal spaces for productive dialogue. The analysis also identified opportunities for policy learning that could enable policy progress on restrictions on marketing of unhealthy foods to children as: taking an incremental approach to policy change, defining permitted (rather than restricted) foods, investing in new public health expertise related to emerging marketing approaches and scaling up of monitoring of impacts. The insights from this study are likely to be relevant to many countries seeking to strengthen regulation of marketing to children, in response to recent global recommendations.

Determination of trace cobalt ions in bottled drinking water samples from Fiji Island by spray-assisted fine droplet formation-liquid phase microextraction based on simultaneous complexation and extraction before flame atomic absorption spectrometer measurement.

In this study, a green, simple and effective preconcentration method named as spray-assisted fine droplet formation-liquid phase microextraction (SAFDF-LPME) before the flame atomic absorption spectrophotometry (FAAS) measurement for cobalt determination was developed. The method reduces the external dispersive solvent usage by using a simple spraying apparatus to obtain fine droplets of the extraction solvent. SAFDF-LPME method also consists of simultaneous complexation and extraction which indicates the environmental benevolence of the developed method. This method minimized the relative errors with high repeatability and accuracy by reducing the experimental steps. The influential parameters such as buffer type, buffer solution volume, extraction solvent/ligand solution volume (spraying cycle), and mixing period were systematically optimized by the univariate optimization procedure. With the optimum parameters applied, the detection power of the FAAS system was enhanced to about 110-folds with respect to 2.2 ng mL-1 detection limit calculated for the proposed method. Bottled drinking water samples from Fiji Islands were used to demonstrate the applicability of the developed method for the accurate determination of trace cobalt in real sample matrices. Percent recovery results obtained between 95.5 and 88.5% showed the suitability of the developed method in the determination of cobalt at trace levels even in complex sample matrices.

BigDataProcessor2: a free and open-source Fiji plugin for inspection and processing of TB sized image data.

SUMMARY: Modern bioimaging and related areas such as sensor technology have undergone tremendous development over the last few years. As a result, contemporary imaging techniques, particularly electron microscopy (EM) and light sheet microscopy, can frequently generate datasets attaining sizes of several terabytes (TB). As a consequence, even seemingly simple data operations such as cropping, chromatic- and drift-corrections and even visualisation, poses challenges when applied to thousands of time points or tiles. To address this we developed BigDataProcessor2-a Fiji plugin facilitating processing workflows for TB sized image datasets. AVAILABILITY AND IMPLEMENTATION: BigDataProcessor2 is available as a Fiji plugin via the BigDataProcessor update site. The application is implemented in Java and the code is publicly available on GitHub (https://github.com/bigdataprocessor/bigdataprocessor2). SUPPLEMENTARY INFORMATION: Supplementary data are available at Bioinformatics online.

Incorporating a gender lens into nutrition and health-related policies in Fiji: analysis of policies and stakeholder perspectives.

BACKGROUND: Gender equality, zero hunger and healthy lives and well-being for all, are three of the Sustainable Development Goals (SDGs) that underpin Fiji's National Development Plan. Work towards each of these goals contributes to the reduction of non-communicable diseases (NCDs). There are gender differences in NCD burden in Fiji. It is, however, unclear whether a gender lens could be more effectively included in nutrition and health-related policies. METHODS: This study consisted of three components: (i) a policy content analysis of gender inclusion in nutrition and health-related policies (n = 11); (ii) policy analysis using the WHO Gender Analysis tool to identify opportunities for strengthening future policy; and (iii) informant interviews (n = 18), to understand perceptions of the prospects for gender considerations in future policies. RESULTS: Gender equality was a goal in seven policies (64%); however, most focused on women of reproductive age. One of the policies was ranked as gender responsive. Main themes from key informant interviews were: 1) a needs-based approach for the focus on specific population groups in policies; 2) gender-related roles and responsibilities around nutrition and health; 3) what is considered "equitable" when it comes to gender, nutrition, and health; 4) current considerations of gender in policies and ideas for further gender inclusion; and 5) barriers and enablers to the inclusion of gender considerations in policies. Informants acknowledged gender differences in the burden of nutrition-related NCDs, yet most did not identify a need for stronger inclusion of gender considerations within policies. CONCLUSIONS: There is considerable scope for greater inclusion of gender in nutrition and health-related policies in Fiji. This could be done by: 1) framing gender considerations in ways that are actionable and inclusive of a range of gender identities; 2) undertaking advocacy through actor networks to highlight the need for gender-responsive nutrition and health-related policies for key stakeholder groups; 3) ensuring that data collected to monitor policy implementation is disaggregated by sex and genders; and 4) promoting equitable participation in nutrition related issues in communities and governance processes. Action on these four areas are likely critical enablers to more gender equitable NCD reduction in Fiji.

Psychometric properties of the Child-OIDP and oral health-related quality of life (OHRQoL) in secondary schools in Suva, Fiji.

BACKGROUND: Oral health-related problems are highly prevalent and, like many other diseases, affect Quality of Life. Although most primary schools in Fiji have supervised school brushing programs and have regular screenings these preventive aspects are missing in secondary schools. OBJECTIVE: To assess the internal consistency reliability, face and content validity of the Child-OIDP questionnaire and determine the oral health-related quality of life in 15-year-olds in Suva, Fiji. METHODS: A cross-sectional prospective study was carried out on 15-year-old children from four secondary schools in Suva, Fiji from 2014 to 2015. All students enrolled in the 10th and 11th year of studies were included. Multi-stage cluster sampling was used to identify the participants and the sample size of 367 was calculated. The Child Oral Impact on Daily Performance (Child-OIDP) self-administered questionnaire was used to collect data and data was analyzed using Epi-Info (3.5.1). RESULTS: A total of 281 students (76.6%) responded, of whom 47.0% experienced at least one impact. Cronbach's alpha for the Child-OIDP frequency items was 0.70 and the corrected item-total correlation ranged from 0.13 to 0.57. The most common performances that were affected were eating (27.8%) and relaxing (12.8%). Performances that were severely and most severely influenced were social contact (23.1%), smiling (16.7%) and relaxing (16.7%). The most common conditions leading to impacts were dental sensitivity (38.4%), dental caries (23.5%) and toothache (21.4%). CONCLUSION: The original version of the Child-OIDP is a reliable index with acceptable internal consistency when used directly in the Fiji setting, however, further studies to validate the tool will be useful. Oral impacts were prevalent, but not severe.

Mobile genes in the human microbiome are structured from global to individual scales.

Recent work has underscored the importance of the microbiome in human health, and has largely attributed differences in phenotype to differences in the species present among individuals. However, mobile genes can confer profoundly different phenotypes on different strains of the same species. Little is known about the function and distribution of mobile genes in the human microbiome, and in particular whether the gene pool is globally homogenous or constrained by human population structure. Here, we investigate this question by comparing the mobile genes found in the microbiomes of 81 metropolitan North Americans with those of 172 agrarian Fiji islanders using a combination of single-cell genomics and metagenomics. We find large differences in mobile gene content between the Fijian and North American microbiomes, with functional variation that mirrors known dietary differences such as the excess of plant-based starch degradation genes found in Fijian individuals. Notably, we also observed differences between the mobile gene pools of neighbouring Fijian villages, even though microbiome composition across villages is similar. Finally, we observe high rates of recombination leading to individual-specific mobile elements, suggesting that the abundance of some genes may reflect environmental selection rather than dispersal limitation. Together, these data support the hypothesis that human activities and behaviours provide selective pressures that shape mobile gene pools, and that acquisition of mobile genes is important for colonizing specific human populations.

Perception of pregnant women towards early antenatal visit in Fiji: a qualitative study.

BACKGROUND: Antenatal Care (ANC) is an opportunity to provide care to prevent potential maternal and new born mortality and morbidity and reduce new born mortality and morbidity. There has been an increase in the number of women receiving early ANC over the last two decades, however, in many developing regions such as Fiji, women are still delaying initiation of ANC. Therefore, the aim of this study is primarily to explore reasons for delayed initiation of ANC appointments and to explore knowledge and perception of pregnant mothers towards early antenatal appointments in Fiji. METHODS: The study uses a qualitative approach. Data was collected among pregnant women more than 18 years of age after 12 weeks of gestation attending their first ANC clinic at the Ba Mission Hospital (BMH) from February 28 to April 2, 2020. Heterogenous purposeful sampling method was used to select 25 pregnant women for the study. A semi-structured open-ended questionnaire was used for face to face in-depth interviews. Data was analyzed manually using thematic content analysis after verbatim transcription of the interviews. RESULTS: The mean age of the participants was 25.8 ± 5.9 years (age range of 19-40 years). The average gestational age of those making a booking for a consultation was 5.4 ± 1.4 months with a range of 4 to 8 months. The majority of women were multigravida (64%) and multiparous (40%). The main themes that emerged from the study were: i) perception of early ANC booking; ii) perceived barriers of early ANC booking and; iii) enabling factors of early ANC booking. Even though pregnant women have a good knowledge of when to initiate ANC, the practice of early booking was influenced by many other factors. CONCLUSIONS: The results of this study highlight the need to change the current booking system. Efforts are needed to attract the hard-to-reach women through outreach visits and increased communication between health care workers and the community with the use of community resources such as community health workers and traditional birth attendants. The media should be used to create awareness on timing and importance of early ANC visits at a community level.
