Prevalence and Determinants of Screen-Viewing in Children Under Two Years in Suva, Fiji.

OBJECTIVE: To determine the prevalence of screen-viewing and factors affecting this behavior among children aged less than two years in Suva, Fiji. METHODS: This cross-sectional study was conducted at three randomly selected maternal and child health (MCH) clinics among parents or accompanying guardians of 379 children. Data collection was carried out using a 20-item self-administrated questionnaire. RESULTS: The prevalence of screen-viewing in children was 66.2%. Screen-viewing was more prevalent in children aged 12-24 months (89%) than in children below 12 months (57%). The risk of screen-viewing was high among those who had parents as daytime caregivers (RR (95% CI) = 0.93 (0.82 - 1.04), P=0.001), iTaukei (RR (95% CI) = 0.79 (0.71-0.87), P=0.001), and children younger than 12 months (RR (95% CI) = 0.64 (0.57-0.71), (P=0.001). Results show that availability of screen devices at home is significantly related to children's screen viewing (RR (95% CI) =1.03 (0.64-1.65), P=0.03). CONCLUSION: The study found early exposure and early adaptation to screen-viewing in children due to several determinants, and suggests the need for anticipatory guidance to parents.

Monitoring of diverse enteric pathogens across environmental and host reservoirs with TaqMan array cards and standard qPCR: a methodological comparison study.

BACKGROUND: Multiple bacteria, viruses, protists, and helminths cause enteric infections that greatly impact human health and wellbeing. These enteropathogens are transmited via several pathways through human, animal, and environmental reservoirs. Individual qPCR assays have been extensively used to detect enteropathogens within these types of samples, whereas the TaqMan array card (TAC), which allows simultaneous detection of multiple enteropathogens, has only previously been validated in human clinical samples. METHODS: In this methodological comparison study, we compared the performance of a custom 48-singleplex TAC relative to standard qPCR. We established the sensitivity and specificity of each method for the detection of eight enteric targets, by using spiked samples with varying levels of PCR inhibition. We then tested the prevalence and abundance of pathogens in wastewater from Melbourne (Australia), and human, animal, and environmental samples from informal settlements in Suva, Fiji using both TAC and qPCR. FINDINGS: Both methods exhibited similarly h specificity (TAC 100%, qPCR 94%), sensitivity (TAC 92%, qPCR 100%), and quantitation accuracy (TAC 91%, qPCR 99%) in non-inhibited sample matrices with spiked gene fragments. PCR inhibitors substantially affected detection via TAC, though this issue was alleviated by ten-fold sample dilution. Among samples from informal settlements, the two techniques performed similarly for detection (89% agreement) and quantitation (R2 0·82) for the eight enteropathogen targets. The TAC additionally included 38 other enteric targets, enabling detection of diverse faecal pathogens and extensive environmental contamination that would be prohibitively labour intensive to assay by standard qPCR. INTERPRETATION: The two techniques produced similar results across diverse sample types, with qPCR prioritising greater sensitivity and quantitation accuracy, and TAC trading small reductions in these for a cost-effective larger enteropathogen panel enabling a greater number of enteric pathogens to be analysed concurrently, which is beneficial given the abundance and variety of enteric pathogens in environments such as urban informal settlements. The ability to monitor multiple enteric pathogens across diverse reservoirs could allow better resolution of pathogen exposure pathways, and the design and monitoring of interventions to reduce pathogen load.

Study design, rationale and methods of the Revitalising Informal Settlements and their Environments (RISE) study: a cluster randomised controlled trial to evaluate environmental and human health impacts of a water-sensitive intervention in informal settlements in Indonesia and Fiji.

INTRODUCTION: Increasing urban populations have led to the growth of informal settlements, with contaminated environments linked to poor human health through a range of interlinked pathways. Here, we describe the design and methods for the Revitalising Informal Settlements and their Environments (RISE) study, a transdisciplinary randomised trial evaluating impacts of an intervention to upgrade urban informal settlements in two Asia-Pacific countries. METHODS AND ANALYSIS: RISE is a cluster randomised controlled trial among 12 settlements in Makassar, Indonesia, and 12 in Suva, Fiji. Six settlements in each country have been randomised to receive the intervention at the outset; the remainder will serve as controls and be offered intervention delivery after trial completion. The intervention involves a water-sensitive approach, delivering site-specific, modular, decentralised infrastructure primarily aimed at improving health by decreasing exposure to environmental faecal contamination. Consenting households within each informal settlement site have been enrolled, with longitudinal assessment to involve health and well-being surveys, and human and environmental sampling. Primary outcomes will be evaluated in children under 5 years of age and include prevalence and diversity of gastrointestinal pathogens, abundance and diversity of antimicrobial resistance (AMR) genes in gastrointestinal microorganisms and markers of gastrointestinal inflammation. Diverse secondary outcomes include changes in microbial contamination; abundance and diversity of pathogens and AMR genes in environmental samples; impacts on ecological biodiversity and microclimates; mosquito vector abundance; anthropometric assessments, nutrition markers and systemic inflammation in children; caregiver-reported and self-reported health symptoms and healthcare utilisation; and measures of individual and community psychological, emotional and economic well-being. The study aims to provide proof-of-concept evidence to inform policies on upgrading of informal settlements to improve environments and human health and well-being. ETHICS: Study protocols have been approved by ethics boards at Monash University, Fiji National University and Hasanuddin University. TRIAL REGISTRATION NUMBER: ACTRN12618000633280; Pre-results.

Exploring persons with disabilities preparedness, perceptions and experiences of disasters in Tuvalu.

BACKGROUND: Historically, Persons with Disabilities (PwDs) are disproportionately affected by disasters. In Pacific Island Countries (PICs), the risks and vulnerabilities of PwDs arise from social inequalities, as well as environmental barriers. As the frequency and intensity of disasters will increase over the next decade, it is critical that the challenges faced by PwDs are addressed and that they are prepared. OBJECTIVE: This study explores disaster preparedness, perceptions, and experiences with disasters among PwDs in Tuvalu. METHODS: This qualitative study was carried out among people with physical and sensory disabilities and without post-traumatic stress disorder (PTSD), who are aged 21 and above. Using grounded theory methodology, semi-structured in-depth interviews were conducted with 24 participants, with 7 then participating in a Focus Group Discussion (FGD). RESULTS: A total of 31 PwDs participated, of which 65% were male and 35% female, with a mean age of 44 ±15.70. The results showed how the PwDs ability to prepare, their perceptions, and experiences with disasters have contributed to their resilience to disasters. CONCLUSION: This study highlights the importance of understanding PwDs lived disaster experience to improve their preparedness and resilience for future disasters. This knowledge will assist government and non-government organisations, communities, and families to develop policies and plans that will enhance the preparedness of PwDs for disasters.

Children's Environmental Health Indicators for Pacific Island Countries.

Healthy environments support the wellbeing of children and the environment thus play a cardinal role in the future of Pacific Island Countries (PICs). Children are more vulnerable and at risk to environmental hazards than adults because they breathe, drink, and eat much more relative to body weight, resulting in greater exposures in the different environments in which children find themselves every day. We examine the role that children’s environmental health indicators (CEHI) can play for PICs to highlight priorities and we prioritise actions to improve children’s environmental health and thus achieve their ‘Healthy Islands’ vision. We conducted a systematic search of relevant documented and publicly available Pacific Island Country information on children’s environmental health indicators using the general Internet, as well as databases such as PubMed, Google Scholar, relevant UN agencies, as well as regional databases. Information on CEHI was available—mainly in grey literature—but not specifically aimed at PICs. Likewise, similar observations were made for peer-reviewed literature. From this review, we compiled summaries and a framework to propose the requirements as well as provide a foundation for the development of CEHI for PICs. CEHI development for PICs should ideally be a multi-sectoral endeavour within each PIC as well as for the region. This can be achieved through public, private, and academic sector initiatives to draw in all sectors of government as well as the relevant UN agencies and regional PIC-representative organisations.

Family structure and health, how companionship acts as a buffer against ill health.

BACKGROUND: Health and well-being are the result of synergistic interactions among a variety of determinants. Family structure and composition are social determinants that may also affect health behaviours and outcomes. This study was performed to examine the associations between family structure and health and to determine the protective effects of support mechanisms to improve quality of health outcome. METHODS: Six hundred people, selected by multistage sampling to obtain a representative population of men and women aged 20-60 living in communities in Japan, were included in this study. Data regarding subjective views of one's own health, family structure, lifestyle and social support were collected through structured face-to-face interviews on home visits. Systolic and diastolic blood pressures, height and weight were measured by trained examiners. The associations between family structure and health after controlling for demographics, lifestyle and social support were examined using logistic and linear regression analyses. RESULTS: Subjects living alone were significantly more likely to be in ill health, as determined using the General Health Questionnaire, in comparison to those in extended families (OR = 3.14). Subjects living alone or as couples were significantly more likely to suffer from severe hypertension in comparison to those living in extended families (OR = 8.25, OR = 4.90). These associations remained after controlling for the influence of lifestyle. Subjects living only with spouse or in nuclear family had higher probabilities of mental ill health in the absence than in the presence of people showing concern for their well-being. CONCLUSION: The results of this study infers that a support mechanism consisting of companionship and the presence of family or other people concerned for one's well being acts as a buffer against deleterious influence of living in small family that will lead to improved quality of health outcome.

Healthy lifestyle behaviour decreasing risks of being bullied, violence and injury.

BACKGROUND: Bullying and violence are problems of aggression in schools among adolescents. Basic daily healthy practices including nutritious diet, hygiene and physical activity are common approaches in comprehensive health promotion programs in school settings, however thier relationship to these aggressive behaviours is vague. We attempted to show the advantages of these healthy lifestyle behaviours in 9 developing countries by examining the association with being frequently bullied, violence and injury. METHODOLOGY/PRINCIPAL FINDINGS: A cross-sectional cross-national survey of 9 countries using the WHO Global School Based Student Health Survey dataset was used. Measurements included experiences of "being frequently bullied" in the preceding 30 days and violence/injury in the past 12 months. Association of risk behaviours (smoking, alcohol, sexual behaviour) and healthy lifestyle (nutrition, hygiene practices, physical activity) to being bullied, and violence/injury were assessed using multivariate logistic regression. Hygiene behaviour showed lower risks of being frequently bullied [male: RR = 0.7 (97.5CI: 0.5, 0.9); female: RR = 0.6 (0.5, 0.8)], and lower risk of experiences of violence/injury [RR = 0.7 (0.5, 0.9) for males], after controlling for risk behaviours, age, education, poverty, and country. CONCLUSION/SIGNIFICANCE: Healthy lifestyle showed an association to decreased relative risk of being frequently bullied and violence/injury in developing countries. A comprehensive approach to risk and health promoting behaviours reducing bullying and violence is encouraged at school settings.
