RESUMO

BACKGROUND: Given the protective effect of nurturing caregivers and families for child and adolescent mental health, there is a need to review and synthesize research evidence regarding the effectiveness of parenting and family interventions in low and middle-income countries, including humanitarian settings. To advance practice, further understanding of the active ingredients of such interventions and implementation factors that lead to effectiveness are essential. METHOD: This systematic review, an update from a previous review, included studies on any parenting or family intervention for children and adolescents aged 0-24, living in a low- or middle-income country, that quantitatively measured child or adolescent mental health outcomes. We searched Global Health, PubMed, PsychINFO, PILOTS and the Cochrane Library databases on the 9th July 2020, and updated on the 12th August 2022. Risk of bias was assessed using an adapted version of the NIH Quality Assessment Tool. We extracted data on: effectiveness outcomes, practice elements included in effective interventions, and implementation challenges and successes. MAIN FINDINGS: We found a total of 80 studies (n = 18,193 participants) representing 64 different family or parenting interventions, 43 of which had evidence of effect for a child or adolescent mental health outcome. Only 3 studies found no effect on child, adolescent or caregiver outcomes. The most common practice elements delivered in effective interventions included caregiver psychoeducation, communication skills, and differential reinforcement. Key implementation strategies and lessons learned included non-specialist delivery, the engagement of fathers, and integrated or multi-sector care to holistically address family needs. PRELIMINARY CONCLUSIONS: Despite a high level of heterogeneity, preliminary findings from the review are promising and support the use of parenting and family interventions to address the wider social ecology of children in low resource and humanitarian contexts. There are remaining gaps in understanding mechanisms of change and the empirical testing of different implementation models. Our findings have implications for better informing task sharing from specialist to non-specialist delivery, and from individual-focused to wider systemic interventions.

RESUMO

Sickle cell disease has a growing global burden falling primarily on low-income countries (LICs) and lower-middle-income countries (LMICs) where comprehensive care is often insufficient, particularly in rural areas. Integrated care models might be beneficial for improving access to care in areas with human resource and infrastructure constraints. As part of the Centre for Integration Science's ongoing efforts to define, systematise, and implement integrated care delivery models for non-communicable diseases (NCDs), this Review explores models of care for sickle cell disease in LICs and LMICs. We identified 99 models from 136 studies, primarily done in tertiary, urban facilities in LMICs. Except for two models of integrated care for concurrent treatment of other conditions, sickle cell disease care was mostly provided in specialised clinics, which are low in number and accessibility. The scarcity of published evidence of models of care for sickle cell disease and integrated care in rural settings of LICs and LMICs shows a need to implement more integrated models to improve access, particularly in rural areas. PEN-Plus, a model of decentralised, integrated care for severe chronic non-communicable diseases, provides an approach to service integration that could fill gaps in access to comprehensive sickle cell disease care in LICs and LMICs.

RESUMO

BACKGROUND: Adolescent malnutrition is a significant public health challenge in low-income and middle-income countries (LMICs), with long-term consequences for health and development. Community-based interventions have the potential to address multiple forms of malnutrition and improve the health outcomes of adolescents. However, there is a limited understanding of the content, implementation and effectiveness of these interventions. This scoping review aims to synthesise evidence on community-based interventions targeting multiple forms of malnutrition among adolescents in LMICs and describe their effects on nutrition and health. METHODS AND ANALYSIS: A comprehensive search strategy will be implemented in multiple databases including MEDLINE (through PubMed), Embase, CENTRAL (through Cochrane Library) and grey literature, covering the period from 1 January 2000 to 14 July 2023. We will follow the Participants, Concept and Context model to design the search strategy. The inclusion criteria encompass randomised controlled trials and quasi-experimental studies focusing on adolescents aged 10-19 years. Various types of interventions, such as micronutrient supplementation, nutrition education, feeding interventions, physical activity and community environment interventions, will be considered. Two reviewers will perform data extraction independently, and, where relevant, risk of bias assessment will be conducted using standard Cochrane risk-of-bias tools. We will follow the PRISMA Extension for Scoping Reviews checklist while reporting results. ETHICS AND DISSEMINATION: The scope of this scoping review is restricted to publicly accessible databases that do not require prior ethical approval for access. The findings of this review will be shared through publications in peer-reviewed journals, and presentations at international and regional conferences and stakeholder meetings in LMICs. SCOPING REVIEW REGISTRATION: The final protocol was registered prospectively with the Open Science Framework on 19 July 2023 (https://osf.io/t2d78).

RESUMO

The coronavirus pandemic that began in December 2019, has had an unprecedented impact on the global economy, health systems and infrastructure, in addition to being responsible for significant mortality and morbidity worldwide. The "new normal" has brought along, unforeseen challenges for the scientific community, owing to obstructions in conducting field-based research in lieu of minimizing exposure through in-person contact. This has had greater ramifications for the LMICs, adding to the already existing concerns. As a response to COVID-19 related movement restrictions, public health researchers across countries had to switch to remote data collections methods. However, impediments like lack of awareness and skepticism among participants, dependence on paper-based prescriptions, dearth of digitized patient records, gaps in connectivity, reliance on smart phones, concerns with participant privacy at home and greater loss to follow-up act as hurdles to carrying out a research study virtually, especially in resource-limited settings. Promoting health literacy through science communication, ensuring digitization of health records in hospitals, and employing measures to encourage research participation among the general public are some steps to tackle barriers to remote research in the long term. COVID-19 may not be a health emergency anymore, but we are not immune to future pandemics. A more holistic approach to research by turning obstacles into opportunities will not just ensure a more comprehensive public health response in the coming time, but also bolster the existing infrastructure for a stronger healthcare system for countries.

RESUMO

OBJECTIVES: Vitamin A supplementation (VAS) can protect children from the adverse health consequences of vitamin A deficiency. Granular data on VAS coverage can guide global and national efforts to achieve universal VAS coverage. To provide geographically precise targeting of VAS programs and to monitor progress in reducing geographic disparities, we aimed to create high-resolution (5 × 5 km2) maps of VAS coverage in children under 5 years across VAS priority countries. STUDY DESIGN: We used cross-sectional data from the Demographic and Health Surveys (DHS) program. METHODS: We used data from the DHS program for United Nations Children's Fund -designated VAS priority countries between 2000 and 2017 with data available from 2005 or later. The outcome variable was the proportion of children under 5 years who received a vitamin A dose in each sampled cluster. We applied a Bayesian geostatistical approach incorporating geographic, climatic, and nutritional covariates to estimate VAS coverage for each cell. We estimated and mapped absolute VAS coverage, Bayesian uncertainty intervals, and exceedance probabilities. RESULTS: Our sample included countries from Latin America and the Caribbean, Asia, and Africa. Most countries had estimated VAS coverage levels <70%, and our exceedance probabilities indicated high certainty that our estimates fell below this threshold in most grid cells. International variations were most notable in the Latin America and the Caribbean region and Africa. Intranational variations were greatest in some South Asian and West and Central African countries. CONCLUSIONS: These prevalence and exceedance maps, especially used with data on indicators of VAS need, could help to improve equity.

RESUMO

BACKGROUND: Adaptation to climate change (CC) is a priority for Small Island Developing States (SIDS) in the Caribbean, as these countries and territories are particularly vulnerable to climate-related events. Primary health care (PHC) is an important contributor to CC adaptation. However, knowledge on how PHC is prepared for CC in Caribbean SIDS is very limited. The aim of this paper is to discuss health system adaptation to climate change, with a focus on PHC. METHODS: We explored the perspectives of PHC professionals in Dominica on PHC adaptation to climate change. Focus group discussions (FGDs) were conducted in each of the seven health districts in Dominica, a Caribbean SIDS, between November 2021 and January 2022. The semi-structured interview guide was based on the Essential Public Health Functions: assessment, access to health care services, policy development and resource allocation. Data coding was organized accordingly. RESULTS: Findings suggest that health care providers perceive climate change as contributing to an increase in NCDs and mental health problems. Climate-related events create barriers to care and exacerbate the chronic deficiencies within the health system, especially in the absence of high-level policy support. Healthcare providers need to take a holistic view of health and act accordingly in terms of disease prevention and health promotion, epidemiological surveillance, and ensuring the widest possible access to healthcare, with a particular focus on the environmental and social determinants of vulnerability. CONCLUSION: The primary health care system is a key stakeholder in the design and operationalization of adaptation and transformative resilience. The Essential Public Health Functions should integrate social and climate and other environmental determinants of health to guide primary care activities to protect the health of communities. This study highlights the need for improved research on the linkages between climate events and health outcomes, surveillance, and development of plans informed by contextual knowledge in the SIDS.

RESUMO

The escalating challenge of antimicrobial resistance (AMR) poses a considerable concern for global health, particularly impacting low- and middle-income countries (LMICs). This article highlights the critical importance of tackling AMR in LMICs by adopting the Global Antimicrobial Stewardship Accreditation Scheme (GAMSAS). GAMSAS is portrayed as a holistic and sustainable strategy for antimicrobial stewardship, extending beyond accreditation to include educational programs, capacity enhancement, improved surveillance, and support for AMS policy research. While acknowledging the global uptake of the scheme, the article highlights its preliminary phase of adoption in LMICs, particularly in high-AMR burden regions like Sub-Saharan Africa. The piece stresses the imperative for LMICs to integrate GAMSAS, underscoring its significance in optimizing antimicrobial usage and patient health outcomes. It advocates for an all-encompassing approach that leverages international cooperation and sustained financial backing, crucial for the effective deployment and enduring success of antimicrobial stewardship efforts in these key areas.

RESUMO

This research aims to identify critical contamination points by nutrients, their possible origin (point and nonpoint sources), their spatial distribution, and possible attenuation by natural and anthropogenic processes. The study area is the Velhas River Basin, located in the Southeast Region of Brazil (17.0°-20.5° S; 43.5°-45.0°W). A historical series of water quality monitoring, land cover map, demographic and agricultural censuses, sewage treatment diagnostics, and local hydrographic networks were used to achieve the objectives. In addition, the regions were divided into incremental areas, enabling individualized analyses of each sub-basin. Descriptive statistics, seasonality, categorized data tests, agglomerative hierarchical cluster analysis, and principal component analysis were used. There was a significant contribution of nutrients in the most important urban agglomeration of the basin, resulting in peak concentrations measured at that place. Although the values were reduced by the mouth (650 km), the percentage of legislation violations remained high. The effects of punctual contamination were intensified by the low percentage of treated sewage in the basin, the absence of adequate treatment technologies to remove nutrients, and the disorderly urbanization. Furthermore, it was estimated that the nutrient load from animal husbandry is approximately 75% of the load from domestic effluents due to the high number of cattle in the basin and the low percentage of forests.

RESUMO

BACKGROUND: Injuries represent a vast and relatively neglected burden of disease affecting low- and middle-income countries (LMICs). While many health systems underperform in treating injured patients, most assessments have not considered the whole system. We integrated findings from 9 methods using a 3 delays approach (delays in seeking, reaching, or receiving care) to prioritise important trauma care health system barriers in Karonga, Northern Malawi, and exemplify a holistic health system assessment approach applicable in comparable settings. METHODS AND FINDINGS: To provide multiple perspectives on each conceptual delay and include data from community-based and facility-based sources, we used 9 methods to examine the injury care health system. The methods were (1) household survey; (2) verbal autopsy analysis; (3) community focus group discussions (FGDs); (4) community photovoice; (5) facility care-pathway process mapping and elucidation of barriers following injury; (6) facility healthcare worker survey; (7) facility assessment survey; (8) clinical vignettes for care process quality assessment of facility-based healthcare workers; and (9) geographic information system (GIS) analysis. Empirical data collection took place in Karonga, Northern Malawi, between July 2019 and February 2020. We used a convergent parallel study design concurrently conducting all data collection before subsequently integrating results for interpretation. For each delay, a matrix was created to juxtapose method-specific data relevant to each barrier identified as driving delays to injury care. Using a consensus approach, we graded the evidence from each method as to whether an identified barrier was important within the health system. We identified 26 barriers to access timely quality injury care evidenced by at least 3 of the 9 study methods. There were 10 barriers at delay 1, 6 at delay 2, and 10 at delay 3. We found that the barriers "cost," "transport," and "physical resources" had the most methods providing strong evidence they were important health system barriers within delays 1 (seeking care), 2 (reaching care), and 3 (receiving care), respectively. Facility process mapping provided evidence for the greatest number of barriers-25 of 26 within the integrated analysis. There were some barriers with notable divergent findings between the community- and facility-based methods, as well as among different community- and facility-based methods, which are discussed. The main limitation of our study is that the framework for grading evidence strength for important health system barriers across the 9 studies was done by author-derived consensus; other researchers might have created a different framework. CONCLUSIONS: By integrating 9 different methods, including qualitative, quantitative, community-, patient-, and healthcare worker-derived data sources, we gained a rich insight into the functioning of this health system's ability to provide injury care. This approach allowed more holistic appraisal of this health system's issues by establishing convergence of evidence across the diverse methods used that the barriers of cost, transport, and physical resources were the most important health system barriers driving delays to seeking, reaching, and receiving injury care, respectively. This offers direction and confidence, over and above that derived from single methodology studies, for prioritising barriers to address through health service development and policy.

RESUMO

Background: Emerging financing strategies in the health sector have been developed to improve the impact of investments and enhance healthcare outcomes. One promising approach is Results-based Financing, which establishes a connection between financial incentives and pre-established performance targets. This innovative approach holds the potential to strengthenhealthcare delivery and strengthen overall healthcare systems.Aim:The scoping review endeavored to systematically delineate the body of evidence pertaining tofacilitators and barriers to the implementation of performance-based financing within the realm of healthcare provision in low-and middle-income nations.Methods:The review used Preferred Reporting Items for Systematic Reviews and a Meta-Analysis extension for Scoping Reviews checklist to select, appraise, and report the findings. We searched PubMed, Web of Science, and Google Scholar databases and grey literature published between January 2000 and March 2022. We conducted the abstract screening with two independent reviewers. We also performed full-article screening. We used the six methodological frameworks proposed by Arksey and O'Malley. The results were thematically analyzed.Results:Of the 1071 searched studies, 34 met the eligibility criteria. 41% of the studies were descriptive, 26% cross-sectional, 18% trial, and 15% cohort studies. The enabling and inhibiting factors of performance-based financing in healthcaredelivery have been identified. Moreover, the review revealed that performance-based financing's influence on service delivery is context-specific.Conclusion:The facilitators and impediments to the effectiveness of performance-based financing in enhancing service delivery are contingent upon a holistic comprehension of the contextual factors, meticulous design, and efficient execution. Factors such as the level of care facilities, presence of community-based initiatives, stakeholder involvement, and participatory design emerge as key facilitators. Conversely, barriers such as communication obstacles, inadequacies in the PBF models, and deficiencies in the healthcare workforce are recognized as inhibitors. By harnessing the insights derived from a multitude of evidence incorporated in this scrutiny, stakeholders can deftly navigate the intricacies of performance-based financing, while also considering the prospective areas for further exploration and research

RESUMO

Traditional food markets are age-old systems that primarily serve the food supply needs of society's less affluent sectors, often operating with minimal infrastructure. These markets are prevalent in low and middle-income countries. However, their hygienic conditions are frequently suboptimal, potentially fostering the emergence and spread of presumptive zoonotic diseases. The recent emergence of zoonotic or potentially zoonotic diseases and their possible links to traditional food markets underscore the need for focused attention on this overlooked issue. The socioeconomic characteristics of traditional food markets reveal that despite the risk of zoonotic pathogen spread, these markets play a crucial role for large segments of the population. These individuals rely on such markets for their livelihood, food, and nutrition. Therefore, a comprehensive set of measures addressing various aspects of traditional food markets is necessary to manage and mitigate the risks of potential zoonotic disease emergence. In this article, we explore various facets of traditional food markets, paying special attention to the risks of zoonotic diseases that urgently require stakeholder attention. We also propose a new market design to prevent the risk of zoonotic spillover and advocate for the development of a Market Hygiene Index for these markets.

RESUMO

If left untreated, HIV has the potential to increase morbidity and mortality rates to 14 times higher than that of HIV and AIDS-free persons of the same sex and age group. Currently, treatment of HIV is by use of ART, which has proved to prolong the lives of people living with HIV (PLWHIV). In addition to ART, HIV patients opt to also use traditional medicines. Moringa oleifera is one of the traditional herbs that is used by HIV patients in developing countries. However, its use is only recommended by non-professionals due to a lack of consensus on the impact of moringa on the health of PLWHIV. Therefore, the goal of this review is to investigate the impact of moringa oleifera on health-related quality of life of PLWHIV. Three scientific databases were accessed from 1 July to 31 August 2022 using as key words "moringa oleifera", "health outcomes", herbal supplementation" and "traditional medicines". Articles published in peer-reviewed journals were selected. 20 articles were retrieved, and 11 articles were excluded since they either did not use a randomised control study design, or were a review. The articles reviewed indicated that moringa supplementation resulted to increases in CD4 cell count and body mass index, improvements in psychological well-being, in management of depression and anxiety and the function of vital body organs and control of cholesterol levels. In conclusion, use of moringa oleifera supplementation improves the health of PLWHIV. It is therefore recommended that health personnel should consider the use of moringa oleifera alongside ART to ensure optimal treatment outcomes.

RESUMO

The past decades have seen the field of oncology becoming far more receptive to integrative oncology. Music therapy has been used to mitigate symptoms and address psychosocial needs in people with cancer as an adjunct to the primary treatment. Providing patients access to sources of aesthetic support, like a deeply personal choice of musical playlist, may help cognitive recovery and elevate mood in patients undergoing treatment or recovery. Cancer care infrastructures around the world are heterogeneous and are more noticeable when it comes to evidence-based integrative oncology practices. In most lower and middle-income countries (LMICs), there is a complete absence of a professional body for music therapy, accredited training programs, and board-certified providers, as well as a lack of personalization in evidence-based approaches. The other critical challenge is the paucity of high-quality peer-reviewed randomized controlled trials evaluating indigenous music interventions. Developing high-quality, unbiased, blinded, randomized controlled trials using indigenous musical genres-based interventions is the best way by which we can find out the impact and potential of music in providing supportive care to cancer patients.

RESUMO

Collaborative research between the global north and global south is common and growing in number. Due to inability of local governments to fund research, global north actors provide the bulk of research funding. While providing mutual benefits, global collaborative research projects are far from ideal. In this paper, we review the authorship discrepancies in global collaborative research, discuss preventive measures in place and their shortfalls, and recommend an intervention to address the problem. Malawi research guidelines recommend collaboration between foreign and local researchers in locally conducted research. However, there is no provision requiring joint authorship in final published papers. Journal recommendations on authorship criteria exist, but they can disadvantage low- and middle-income country researchers in collaborative projects because of exclusionary interpretations of guidelines. For example, the requirement for authors to make substantial contributions to conception or design of the work may favor research grant holders, often from the global north. Systematic and holistic changes proposed to address power asymmetries at the core of the problem have been proposed. However, these proposals may take a long time to produce change. Ad interim, local institutions can take more direct action to address inequalities by establishing offices of research integrity to enforce mandates to increase opportunities for authorship in collaborative research.

RESUMO

Safe levels of heavy metals in the surface water and sediment of the eastern Bay of Bengal coast have not been universally established. Current study characterized heavy metals such as arsenic (As), chromium (Cr), cadmium (Cd) and lead (Pb) in surface water and sediments of the most important fishing resource at the eastern Bay of Bengal coast, Bangladesh. Both water and sediment samples were analyzed using inductively coupled plasma mass spectrometer. Considering both of the seasons, the mean concentrations of Cr, As, Cd, and Pb in water samples were 33.25, 8.14, 0.48, and 21.14 µg/L, respectively and in sediment were 30.47, 4.48, 0.20, and 19.98 mg/kg, respectively. Heavy metals concentration in water samples surpassed the acceptable limits of usable water quality, indicating that water from this water resource is not safe for drinking, cooking, bathing, and any other uses. Enrichment factors also directed minor enrichment of heavy metals in sediment of the coast. Other indexes for ecological risk assessment such as pollution load index (PLI), contamination factor (CF), geoaccumulation index (Igeo), modified contamination degree (mCd), and potential ecological risk index (PERI) also indicated that sediment of the coastal watershed was low contamination. In-depth inventorying of heavy metals in both water and sediment of the study area are required to determine ecosystem health for holistic risk assessment and management.

RESUMO

Counterfeit and substandard products continue to bedevil public health in developing countries across the global South. Despite the growing recognition of the importance of this issue, there remains a critical gap in the scholarly discourse on how dysfunctional institutions in developing countries can create conditions that lead to the detrimental public health effects of counterfeiting. Drawing on insights from key stakeholders in Ghana, this research illuminates the mechanisms through which institutional deficiencies shape the detrimental effects of counterfeiting. The study led to the identification of three sequential and interconnected unfolding effects of counterfeiting, encompassing: tracing the growth and spread of deceptive counterfeiting to factors such as inadequate inspection and authentication of products, as well as the phenomenon of mixing counterfeit and second-hand products (Phase 1); highlighting the potential health and fire hazards stemming from policy and regulatory gaps (Phase 2); and then illuminating stakeholder mobilization and interventions (Phase 3). By exploring the linkages between these three phases, the study advances a more holistic view of the proliferation of counterfeit products, encapsulating the interconnected nature of its origins linked to the evolution of other phenomena, such as the growth of second-hand products in developing countries, and its impacts on society and public health.

RESUMO

Blended complementary foods from cereals and high-protein sources are used worldwide to cope with infants' malnutrition. However, the usefulness of the food matrix during traditional processes reaches suboptimal effectiveness due to cereal gelatinization and viscosity, which reduce consumption. The interplay between nutritional and physical qualities needed for weaning children presents further significant constraints. A combination of processing methods can improve and optimize the overall product quality. This paper investigated the nutritional, functional, and anti-nutritional factors of a complementary infant porridge made by combining fermented sorghum flour with germinated bottle gourd seed flour. Overall, the combination improved the functional and physical properties of the porridge suitable for children of 10 months and over. A serving of 100 g would contribute 115-145% and 23-31% of the recommended nutritional intake of protein and energy, respectively, for low breast milk energy between 6-24 months. The results demonstrate that a combination of strategies and technologies are needed to balance nutritional and physical quality.

RESUMO

Every year, an estimated 21 million girls aged 15-19 years become pregnant in low-income and middle-income countries (LMICs). Policy responses have focused on reducing the adolescent birth rate whereas efforts to support pregnant adolescents have developed more slowly. We did a systematic review of interventions addressing any health-related outcome for pregnant adolescents and their newborn babies in LMICs and mapped its results to a framework describing high-quality health systems for pregnant adolescents. Although we identified some promising interventions, such as micronutrient supplementation, conditional cash transfers, and well facilitated group care, most studies were at high risk of bias and there were substantial gaps in evidence. These included major gaps in delivery, abortion, and postnatal care, and mental health, violence, and substance misuse-related outcomes. We recommend that the fields of adolescent, maternal, and sexual and reproductive health collaborate to develop more adolescent-inclusive maternal health care and research, and specific interventions for pregnant adolescents. We outline steps to develop high-quality, evidence-based care for the millions of pregnant adolescents and their newborns who currently do not receive this.

RESUMO

BACKGROUND: Undernutrition in the critical first 1000 days of life is the most common form of childhood malnutrition, and a significant problem in low- and middle-income countries (LMICs). The effects of undernutrition in children aged under five years are wide-ranging and include increased susceptibility to and severity of infections; impaired physical and cognitive development, which diminishes school and work performance later in life; and death. Growth monitoring and promotion (GMP) is a complex intervention that comprises regular measurement and charting of growth combined with promotion activities. Policymakers, particularly in international aid agencies, have differing and changeable interpretations and perceptions of the purpose of GMP. The effectiveness of GMP as an approach to preventing malnutrition remains a subject of debate, particularly regarding the added value of growth monitoring compared with promotion alone. OBJECTIVES: To evaluate the effectiveness of child growth monitoring and promotion for identifying and addressing faltering growth, improving infant and child feeding practices, and promoting contact with and use of health services in children under five years of age in low- and middle-income countries. SEARCH METHODS: We used standard, extensive Cochrane search methods. The latest search date was 3 November 2022. SELECTION CRITERIA: We included randomised controlled trials (RCTs), cohort studies, and controlled before-after studies that compared GMP with standard care or nutrition education alone in non-hospitalised children aged under five years. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods to conduct a narrative synthesis. Our primary outcomes were anthropometric indicators, infant and child feeding practices, and health service usage. Secondary outcomes were frequency and severity of childhood illnesses, and mortality. We used GRADE to assess the certainty of evidence for each primary outcome. MAIN RESULTS: We included six studies reported in eight publications. We grouped the findings according to intervention. Community-based growth monitoring and promotion (without supplementary feeding) versus standard care We are unsure if GMP compared to standard care improves infant and child feeding practices, as measured at 24 months by the proportion of infants who have fluids other than breast milk introduced early (49.7% versus 70.5%; 1 study; 4296 observations; very low-certainty evidence). We are unsure if GMP improves health service usage, as measured at 24 months by the proportion of children who receive vitamin A (72.5% versus 62.9%; 1 study; 4296 observations; very low-certainty evidence) and the proportion of children who receive deworming (29.2% versus 14.6%; 1 study; 4296 observations; very low-certainty evidence). No studies reported selected anthropometric indicators (weight-for-age z-score or height-for-age z-score) at 12 or 24 months, infant and child feeding practices at 12 months, or health service usage at 12 months. Community-based growth monitoring and promotion (with supplementary feeding) versus standard care Two studies (with 569 participants) reported the mean weight-for-age z-score at 12 months, providing very low-certainty evidence: in one study, there was little or no difference between GMP and standard care (mean difference (MD) -0.07, 95% confidence interval (CI) -0.19 to 0.06); in the other study, mean weight-for-age z-score worsened in both groups, but we were unable to calculate a relative effect. GMP versus standard care may make little to no difference to the mean height-for-age z-score at 12 months (MD -0.15, 95% CI -0.34 to 0.04; 1 study, 337 participants; low-certainty evidence). Two studies (with 564 participants) reported a range of outcome measures related to infant and child feeding practices at 12 months, showing little or no difference between the groups (very low-certainty evidence). No studies reported health service usage at 12 or 24 months, feeding practices at 24 months, or selected anthropometric indicators at 24 months. AUTHORS' CONCLUSIONS: There is limited uncertain evidence on the effectiveness of GMP for identifying and addressing faltering growth, improving infant and child feeding practices, and promoting contact with and use of health services in children aged under five years in LMICs. Future studies should explore the reasons for the apparent limited impact of GMP on key child health indicators. Reporting of GMP interventions and important outcomes must be transparent and consistent.

RESUMO

BACKGROUND: There is an urgent global call for health systems to strengthen access to quality sexual, reproductive, maternal, newborn and adolescent health, particularly for the most vulnerable. Professional midwives with enabling environments are identified as an important solution. However, a multitude of barriers prevent midwives from fully realizing their potential. Effective interventions to address known barriers and enable midwives and quality sexual, reproductive, maternal, newborn and adolescent health are less well known. This review intends to evaluate the literature on (1) introducing midwives in low- and middle-income countries, and (2) on mentoring as a facilitator to enable midwives and those in midwifery roles to improve sexual, reproductive, maternal, newborn and adolescent health service quality within health systems. METHODS: An integrative systematic literature review was conducted, guided by the Population, Intervention, Comparison, Outcome framework. Articles were reviewed for quality and relevance using the Gough weight-of-evidence framework and themes were identified. A master table categorized articles by Gough score, methodology, country of focus, topic areas, themes, classification of midwives, and mentorship model. The World Health Organization health systems building block framework was applied for data extraction and analysis. RESULTS: Fifty-three articles were included: 13 were rated as high, 36 as medium, and four as low according to the Gough criteria. Studies that focused on midwives primarily highlighted human resources, governance, and service delivery while those focused on mentoring were more likely to highlight quality services, lifesaving commodities, and health information systems. Midwives whose pre-service education met global standards were found to have more efficacy. The most effective mentoring packages were comprehensive, integrated into existing systems, and involved managers. CONCLUSIONS: Effectively changing sexual, reproductive, maternal, newborn and adolescent health systems is complex. Globally standard midwives and a comprehensive mentoring package show effectiveness in improving service quality and utilization. TRIAL REGISTRATION: The protocol is registered in PROSPERO (CRD42022367657).
