Global Health Action最新文献

Background: During the initial phase of the COVID-19 pandemic, reductions in air pollution were globally observed owing to decreased human activities, underscoring the potential for cleaner air through shifts in human behaviour.

Objectives: The objective of the present study was to hypothetically estimate the resulting population health impacts in Malmö, Sweden, if these improvements in air quality were to become permanent.

Methods: We utilized air pollution data from two measurement campaigns conducted in the spring of 2019 and the spring of 2020 for our Health Impact Assessment, applying standard methods. This assessment involved making assumptions about baseline population risk and using established concentration-response functions.

Results: In the spring of 2020, the NO2 concentrations exhibited an average decrease of 6.6 μg/m3 (42%) decrease and PM2.5 concentrations a 1.9 μg/m3 (22%) decrease, compared to the spring of 2019. If sustained, such improvements could lead to an estimated 1-3% decrease in premature deaths, a 2% decrease in preeclampsia cases, a 6% decrease in low birthweight children, a 4% decrease in bronchitis cases among children, a 2% decrease in asthma cases, a 0.2% decrease in hospital admissions for respiratory diagnoses, and an estimated 11% decrease in dementia cases annually.

Conclusion: The findings illustrate the potential for enhanced health in Malmö due to improved air quality. Efforts to combat air pollution and implement long-term strategies, such as those targeting urban mobility and commuting patterns, are essential for the health and well-being of both local and global populations.

Background: Emigration of health workers has emerged as a significant obstacle in Iran, compelling policymakers to implement a diverse range of interventions and reforms to enhance healthcare services. It is imperative to comprehend the efficacy of emigration control interventions. To explore the intricate dynamics of elite emigration, this study employs a system dynamics modeling approach. The objective is to scrutinize Iranian health workers' emigration, examine the relationships, and evaluate the impact of various factors involved.

Objectives: The general purpose of this study is to analyze the policy interventions affecting the emigration of human resources in the field of health in Iran based on the system's dynamic approach.

Method: The research consists of four phases including analyzing the emigration status of health workers in developing countries, studying health personnel emigration in Iran, developing a System Dynamics (SD) model, and determining evidence-based policy interventions to address health worker emigration. These phases involve realist review, document analysis, qualitative interviews, data integration, and policy scenario planning. The primary objective is to gain a profound understanding of the underlying causes, mechanisms, and consequences of migration, as well as assess the impact of policies, in order to prioritize effective interventions.

Results: It seems that the SD model developed in this study can highlight the interconnectedness of various factors that influence health worker emigration, including demographic changes, economic conditions, and characteristics of healthcare systems.

Conclusion: This study uses a systems dynamics approach to analyze health worker emigration from Iran, focusing on policies that promote retention and explore the implications of emigration on the healthcare system. By examining interrelationships and feedback loops within the healthcare system and socioeconomic factors, the study aims to identify effective policy interventions that can mitigate the negative effects of emigration.

Background: Although there is increasing awareness of the health risks of air pollution as a global issue, few studies have focused on the methods for assessing individuals' perceptions of these risks. This scoping review aimed to identify previous research evaluating individuals' perceptions of air pollution and its health effects, and to explore the measurement of perceptions, as a key resource for health behaviour.

Methods: The review followed the methodological framework proposed by Arksey and O'Malley. PubMed and Web of Science were searched. After initial and full-text screening, we further selected studies with standardised scales that had previously been tested for reliability and validity in assessing awareness and perceptions.

Results: After full-text screening, 95 studies were identified. 'Perception/awareness of air quality' was often measured, as well as 'Perception of health risk.' Only nine studies (9.5%) used validated scaled questionnaires. There was considerable variation in the scales used to measure the multiple dimensions of risk perception for air pollution.

Conclusion: Few studies used structured scales to quantify individuals' perceptions, limiting comparisons among studies. Standardised methods for measuring health risk perception are needed.

Frameworks conceptualising the quality of care abound and vary; some concentrate on specific aspects such as safety, effectiveness, others all-encompassing. However, to our knowledge, tailoring to systematically arrive at a comprehensive care for chronic conditions quality (CCCQ) framework has never been done. We conducted a scoping review and Delphi survey to produce a CCCQ framework, comprehensively delineating aims, determinants and measurable attributes. With the assumption that specific groups (people with chronic conditions, care providers, financiers, policy-makers, etc.) view quality of care differently, we analysed 48 scientific and 26 grey literature deductively and inductively using the Institute of Medicine's quality of care framework as the foundation. We produced a zero-version of the quality of chronic care framework, detailing aims, healthcare system determinants, and measurement mechanisms. This was presented in a Delphi survey to 49 experts with diverse chronic care expertise/experience around the world. Consensus was obtained after the first round, with the panel providing suggestions and justifications to expand the agreed-upon components. Through this exercise, a comprehensive CCCQ framework encompassing the journey through healthcare of people with chronic conditions was developed. The framework specifies seven CCCQ 'aims' and identifies health system determinants which can be acted upon with 'organising principles' and measured through chronic care quality 'attributes' related to structures, processes and outcomes. Tailoring quality of care based on the nature of the diseases/conditions and considering different views can be done to ensure a comprehensive offer of healthcare services, and towards better outcomes that are acceptable to both the health system and people with chronic conditions (PwCC).

Background: The COVID-19 pandemic has revealed clear deficiencies in global public health policies and healthcare systems when confronted with the emergence of a novel and deadly infectious disease.

Objectives: With 4 years elapsed since the onset of the pandemic, ample data now exist to analyse the associations between the implementation of diverse public health policies, sociodemographic factors and COVID-19 mortality rates.

Methods: This study utilised the dataset compiled by 'Our World in Data' spanning the period of the COVID-19 pandemic from 2020 to 2022. Stochastic frontier analysis was employed to assess the influencing factors and their relationship with mortality rates resulting from COVID-19 infections across 156 countries or regions.

Results: This study yielded several key findings: (1) There remains a 33% margin for improvement in the global mortality rate concerning the COVID-19 pandemic; (2) During the initial stage of the pandemic, when an effective vaccine was not yet available, implementing public health control policies could reduce both the infection and mortality rates; (3) Areas characterised by higher population densities, a greater proportion of individuals aged 65 and over, and elevated prevalence rates of diabetes demonstrated higher mortality rates; and (4) Increasing vaccination coverage emerged as an effective strategy for reducing mortality rates.

Conclusions: As our understanding of the COVID-19 virus improves, global economies and social interactions have gradually returned to normality. It is anticipated that the findings of this study can serve as a valuable reference in combating potential future pandemics caused by unknown viruses.

Background: In low- and middle-income countries, the double burden of malnutrition is prevalent. Many countries in Africa are currently confronted with overweight and obesity, particularly among women, coupled with an increase in the prevalence of non-communicable diseases.

Objective: This study examines trends in overweight and obesity among Ethiopian women of reproductive age from 2005 to 2016, and identifies associated factors.

Methods: We used three consecutive datasets from 2005 (n = 14070), 2011 (n = 16515), and 2016 (n = 15683) demographic health survey years. Multilevel logistic regression was used to identify the determinant factors among individual- and cluster-level variables.

Results: The prevalence of overweight and obesity among reproductive women in Ethiopia increased steadily from 6.09% in 2005 to 8.54% in 2011, and 10.16% in 2016. However, mixed patterns were observed among the regions of the country. We found that age, education, living in urban areas, and living in a rich community are associated with becoming overweight and obese. For instance, the odds of becoming overweight and obese among women aged 35-49 were higher than those among women aged 15-24 (odds ratio [OR] = 3.62, 95% Confidence Interval [CI]:2.64-4.97). Women who completed secondary school have higher odds than those without formal education (OR = 1.64, 95% CI:1.19-2.26).

Conclusion: To our knowledge, this is the first study to investigate trends in the nationwide prevalence of overweight and obesity and the associated factors among Ethiopian women. This study warrants further follow-up research to identify the pathways between overweight and obesity and their probable factors.

Background: Postpartum depression is associated with low socioeconomic status, adverse birthing processes, and life stress. Increasing evidence of mistreatment during childbirth, negative birth experiences, and poor quality of maternal care is of global concern.

Objective: To assess the risk of experiencing depressive symptoms among postpartum women exposed to mistreatment during institutional birthing in Nepal.

Method: We conducted a prospective cohort study from 29 March to 19 August 2022. Of 1629 women who gave birth in a hospital in Nepal, 1222 were assessed for mistreatment during childbirth and depressive symptoms using the Edinburgh Postnatal Depression Scale. We used binomial generalized linear mixed model to examine the risk ratio of postpartum depressive symptoms in women exposed to mistreatment during childbirth.

Results: The prevalence of postpartum depressive symptoms was 4.4%. Women exposed to mistreatment during childbirth were almost fifty percent more likely to have postpartum depressive symptoms (cRR 1.47; 95% CI 1.14, 1.89; p = 0.003) compared with the unexposed group. Furthermore, adolescent mothers exposed to mistreatment during childbirth had a seventy percent increased risk of depressive symptoms (aRR 1.72; 95% CI 1.23, 2.41; p = 0.002). Similarly, women who gave birth to female infants were thirty percent more likely to experience postpartum depressive symptoms (aRR 1.32; 95% CI 1.01-1.74; p = 0.039).

Conclusion: We observed an association between postpartum depressive symptoms and mistreatment during institutional births in Nepal. The implementation of appropriate respectful maternity care during childbirth and also routine screening for depressive symptoms is critical to improving perinatal mental health and well-being.

Background: Gestational diabetes mellitus (GDM) is an abnormal glucose metabolism diagnosed during pregnancy that can have serious adverse consequences for mother and child. GDM is an exceptional health condition, as its management serves not only as treatment but also as prevention, reducing the risk of future diabetes in mother and child.

Objectives: This qualitative study aimed to explore how pregnant women experience and respond to GDM, focusing particularly on the role of the family environment in shaping women's experiences.

Methods: The research was carried out in Vietnam's Thái Bình province in April-May 2023. We conducted in-depth ethnographic interviews with 21 women with GDM, visiting them in their homes. Our theoretical starting point was phenomenological anthropology, and the data were analysed using a thematic analysis approach.

Results: At the centre of women's experiences was the contrast between GDM as a biomedical and a social condition. Whereas GDM was biomedically diagnosed and managed in the healthcare system, it was often deemed insignificant or non-existent by family members. This made GDM a biomedically present but socially absent health condition. This paradox posed challenges to women's GDM self-care, placing them in pioneering social positions.

Conclusions: The biomedical presence yet social absence of GDM turned women into pioneers at biomedical, digital, epidemiological, and family frontiers. This article calls for appreciation of pregnant women's pioneering roles and for health systems action to involve women and families in the development of GDM policies and programmes at a time of sweeping global health changes.

Background: Communities in which adolescent pregnancy and safe abortion care are taboo may benefit from culturally appropriate information, education, and communication.

Objective: This ethnographic and participatory action research (PAR) elicited community members' perceptions to adolescent pregnancy: which then informed dialogue-drama development in Burmese and Karen language for undocumented migrants on the Thailand-Myanmar border.

Methods: PAR was conducted in Karen and Burmese language. Interviews and discussions elicited perceptions of community members about adolescent pregnancy. These were analysed for themes and using the fishbone technique, to determine the objectives for the drama. After developing the structure and content of the drama it was piloted, revised, and performed in communities. Responses and impact of the drama were recorded. The team reflected on the drama as a method for health messaging.

Results: In 2022, themes of responsibility, communication, and experiences of adolescent pregnancy emerged from 10 interviews and 6 discussions with community members. The fishbone technique established three dramatic objectives, woven into a teenage love story with an unplanned pregnancy, to raise community awareness of i) adolescent pregnancy, ii) contraception, and iii) choice in unexpected pregnancy. Post-drama feedback from 11 migrant communities (1,238 participants) was positive although some community members voiced concerns. Given the logistical challenges of conducting the drama in person, a film will be created for wider dissemination.

Conclusions: Participatory action research resulted in a culturally-nuanced performance, with communities requesting further performances and awareness on adolescent pregnancy and safe abortion care. Video is likely to be a more sustainable option.

Background/aims: Paediatric surgical care is a critical component of child health and basic universal health coverage and therefore should be included in comprehensive evaluations of surgical capacity. This study adapted and validated the Children's Surgical Assessment Tool (CSAT), a tool developed for district and tertiary hospitals in Nigeria to evaluate hospital infrastructure, workforce, service delivery, financing, and training capacity for paediatric surgery, for use in district hospitals in Rwanda.

Methods: We used a three-round modified Delphi process to adapt the CSAT to the Rwandan context. An expert panel of surgeons, anaesthesiologists, paediatricians, and health systems strengthening experts were invited to participate based on their experience with paediatric surgical or anaesthetic care at district hospitals or with health systems strengthening in the Rwandan context. We used the Content Validity Index to validate the final tool.

Results: The adapted tool had a final score of 0.84 on the Content Validity Index, indicating a high level of agreement among the expert panel. The final tool comprised 171 items across five domains: facility characteristics, service delivery, workforce, financing, and training/research.

Conclusion: The adapted CSAT is appropriate for use in district hospitals in Rwanda to evaluate the capacity for paediatric surgery. This study provides a framework for adapting and validating a comprehensive paediatric surgical assessment tool to local contexts in LMICs and used in similar settings in sub-Saharan Africa.
