Project description:Introduction Fertility levels among adolescents remain high in many settings. The objective of this paper was to review the available literature about postpartum and lactational amenorrhoea among adolescents in low-income and middle-income countries (LMICs). Methods We searched Medline, Embase, Global Health and CINAHL Plus databases using terms capturing adolescence and lactational or postpartum amenorrhoea. Inclusion criteria included publication date since 1990, data from LMICs, and topic related to lactational amenorrhoea as a postpartum family planning method or as an effect of (exclusive) breast feeding among adolescents. Thematic analysis and narrative synthesis were applied to summarise and interpret the findings. Results We screened 982 titles and abstracts, reviewed 75 full-text articles and included nine. Eight studies assessed data from a single country (three from India, two from Bangladesh, two from Turkey, one from Nigeria). One study using Demographic and Health Survey data included 37 different LMICs. The five studies measuring duration of postpartum or lactational amenorrhoea reported a wide range of durations across the contexts examined. Four studies (from Bangladesh, Nigeria and Turkey) examined outcomes related to the use of lactational amenorrhoea as a family planning method among adolescents. We did not find any studies assessing adolescents’ knowledge of lactational amenorrhoea as a postpartum family planning method. Likewise, little is known about the effectiveness of lactational amenorrhoea method among adolescents using sufficiently large samples and follow-up time. Conclusion The available evidence on lactational amenorrhoea among adolescents in LMICs is scarce. Given the potential contribution of lactational amenorrhoea to prevention of short interpregnancy intervals among adolescents and young women, there is a need for a better understanding of the duration of lactational amenorrhoea, and the knowledge and effective use of lactational amenorrhoea method for family planning among adolescents in a wider range of LMIC settings.

Project description:Food environment research is increasingly gaining prominence in low- and middle-income countries (LMICs). However, in the absence of a systematic review of the literature, little is known about the emerging body of evidence from these settings. This systematic scoping review aims to address this gap. A systematic search of 6 databases was conducted in December 2017 and retrieved 920 records. In total, 70 peer-reviewed articles met the eligibility criteria and were included. Collectively, articles spanned 22 LMICs, including upper-middle-income countries (n = 49, 70%) and lower-middle-income countries (n = 18, 26%). No articles included low-income countries. Articles featured quantitative (n = 45, 64%), qualitative (n = 17, 24%), and mixed-method designs (n = 11, 8%). Studies analyzed the food environment at national, community, school, and household scales. Twenty-three articles (55%) assessed associations between food environment exposures and outcomes of interest, including diets (n = 14), nutrition status (n = 13), and health (n = 1). Food availability was associated with dietary outcomes at the community and school scales across multiple LMICs, although associations varied by vendor type. Evidence regarding associations between the food environment and nutrition and health outcomes was inconclusive. The paucity of evidence from high-quality studies is a severe limitation, highlighting the critical need for improved study designs and standardized methods and metrics. Future food environment research must address low-income and lower-middle-income countries, and include the full spectrum of dietary, nutrition, and health outcomes. Improving the quality of food environment research will be critical to the design of feasible, appropriate, and effective interventions to improve public health nutrition in LMICs.

Project description:PurposeTo conduct an expert-led process for identifying research priorities for eight areas of adolescent health in low- and middle-income countries. Specific adolescent health areas included communicable diseases prevention and management, injuries and violence, mental health, noncommunicable diseases management, nutrition, physical activity, substance use, and health policy.MethodsWe used a modified version of the Child Health and Nutrition Research Initiative methodology for reaching consensus on research priorities. In a three phase process, we (1) identified research and program experts with wide-ranging backgrounds and experiences from all geographic regions through systematic searches and key informants; (2) invited these experts to propose research questions related to descriptive epidemiology, interventions (discovery, development/testing, and delivery/implementation), and health policy/systems; and (3) asked the experts to prioritize the research questions based on five criteria: clarity, answerability, importance or impact, implementation, and equity.ResultsA total of 142 experts submitted 512 questions which were edited and reduced to 303 for scoring. Overall, the types of the top 10 research questions in each of the eight health areas included descriptive epidemiology (26%), interventions: discovery (11%), development/testing (25%), delivery (33%), and policy, health and social systems (5%). Across health areas, the top questions highlighted integration of health services, vulnerable populations, and different health platforms (such as primary care, schools, families/parents, and interactive media).ConclusionsPriority questions have been identified for research in eight key areas of adolescent health in low- and middle-income countries. These expert-generated questions may be used by donors, program managers, and researchers to prioritize and stimulate research in adolescent health.

Project description:ImportanceMany randomized clinical trials (RCTs) led by high-income countries (HICs) now enroll patients from lower middle-income countries (LMICs) and upper middle-income countries (UMICs). Although enrolling diverse populations promotes research collaborations, there are issues regarding which countries participate in RCTs and how this participation may contribute to global research.ObjectiveTo describe which UMICs and LMICs participate in RCTs led by HICs.Design, setting, and participantsA cross-sectional study of all oncology RCTs published globally during January 1, 2014, to December 31, 2017, was conducted. The study cohort was restricted to RCTs led by HICs that enrolled participants from LMICs and UMICs. Study analyses were conducted in November 1, 2021, to May 31, 2022.Main outcomes and measuresA bibliometric approach (Web of Science 2007-2017) was used to explore whether RCT participation was proportional to other measures of cancer research activity. Participation in RCTs (ie, percentage of RCTs in the cohort in which each LMIC and UMIC participated) was compared with country-level cancer research bibliometric output (ie, percentage of total cancer research bibliometric output from the same group of countries that came from a specific LMIC and UMIC).ResultsAmong the 636 HIC-led RCTs, 186 trials (29%) enrolled patients in LMICs (n = 84 trials involving 11 LMICs) and/or UMICs (n = 181 trials involving 26 UMICs). The most common participating LMICs were India (42 [50%]), Ukraine (39 [46%]), Philippines (23 [27%]), and Egypt (12 [14%]). The most common participating UMICs were Russia (115 [64%]), Brazil (94 [52%]), Romania (62 [34%]), China (56 [31%]), Mexico (56 [31%]), and South Africa (54 [30%]). Several LMICs are overrepresented in the cohort of RCTs based on proportional cancer research bibliometric output: Ukraine (46% of RCTs but 2% of cancer research bibliometric output), Philippines (27% RCTs, 1% output), and Georgia (8% RCTs, 0.2% output). Overrepresented UMICs include Russia (64% RCTs, 2% output), Romania (34% RCTs, 2% output), Mexico (31% RCTs, 2% output), and South Africa (30% RCTs, 1% output).Conclusions and relevanceIn this cross-sectional study, a substantial proportion of RCTs led by HICs enrolled patients in LMICs and UMICs. The LMICs and UMICs that participated in these trials did not match overall cancer bibliometric output as a surrogate for research ecosystem maturity. Reasons for this apparent discordance and how these data may inform future capacity-strengthening activities require further study.

Project description:IntroductionPast research has shown relationships between stress during pregnancy, and related psychosocial health measures such as anxiety and depressive symptoms, with infant, child, and adult outcomes. However, most research is from high-income countries. We conducted a scoping review to identify research studies on prenatal stress and outcomes of the pregnancy or offspring in low- and middle-income countries (LMICs), and to synthesize the stress measures and outcomes assessed, the findings observed, and directions for future research.MethodsWe searched PubMed, Scopus, and PsycINFO for English-language abstracts published from Jan 1960-Jan 2017. Search terms were related to stress and psychosocial health; pregnancy; infant or child development; and LMICs.Results48 articles were identified. Sixty percent of studies were in upper-middle, 25% in lower-middle, and 15% in low income countries. Most studies used questionnaires, either existing or tailor-made, to assess stress. Eight assessed cortisol. Most studies (n = 31) assessed infant outcomes at birth, particularly gestational age or preterm birth (n = 22, 12 showing significant relationships), and birthweight (n = 21, 14 showing significant relationships). Five studies analyzed outcomes later in infancy such as temperament and motor development, all showing significant results; and nine in childhood such as behavioral development, asthma, and physical growth, with eight showing significant results.ConclusionsResults highlight the importance of prenatal stress on infant and child outcomes in LMICs. Methods used in high-income countries are successfully employed in LMICs, but tailored tools remain necessary. Careful assessment of covariates is needed to foster analyses of interactive effects and pathways. Studies including longer-term follow-up should be prioritized.

Project description:IntroductionConducting research with children in low/middle-income countries (LMIC) requires consideration of socioeconomic inequalities and cultural and linguistic differences. Our objective was to survey the literature on informed consent in paediatric LMIC research, assessing for practical guidance for culturally and linguistically appropriate procedures.MethodsWe conducted a scoping review on informed consent in paediatric LMIC research searching the PubMed, Web of Science and PsycINFO databases. Eligible articles were published in English, from any date range, of any study design or format.ResultsThe search identified 2027 references, of which 50 were included in the analysis following full-text review. Reviewed guidelines emphasised individual, informed and voluntary consent from parents and caregivers. Reviewed articles provided detailed practical guidance on adapting these guiding principles to LMIC settings, including considerations for community engagement, verbal or other alternative consent procedures for low-literacy settings or less commonly spoken languages and guarding against therapeutic misconception by caregivers. There was uncertainty, however, on how to best protect individual autonomy, especially when influenced by gender dynamics, leadership hierarchies or the social status of researchers themselves. There was, furthermore, limited research discussing the special case of research involving adolescents or of procedures for documenting assent by participating children.ConclusionsA scoping review of paediatric research in LMICs revealed substantial guidance on several features of culturally appropriate informed consent. However, additional research and guidance is needed, especially in the areas of gender imbalances, research with adolescents and children's own assent to participate in research.

Project description:Artificial intelligence (AI) has been integrated into dentistry for improvement of current dental practice. While many studies have explored the utilization of AI in various fields, the potential of AI in dentistry, particularly in low-middle income countries (LMICs) remains understudied. This scoping review aimed to study the existing literature on the applications of artificial intelligence in dentistry in low-middle income countries. A comprehensive search strategy was applied utilizing three major databases: PubMed, Scopus, and EBSCO Dentistry & Oral Sciences Source. The search strategy included keywords related to AI, Dentistry, and LMICs. The initial search yielded a total of 1587, out of which 25 articles were included in this review. Our findings demonstrated that limited studies have been carried out in LMICs in terms of AI and dentistry. Most of the studies were related to Orthodontics. In addition gaps in literature were noted such as cost utility and patient experience were not mentioned in the included studies.

Project description:BackgroundAn estimated 85% of research resources are wasted worldwide, while there is growing demand for context-based evidence-informed health policymaking. In low- and middle-income countries (LMICs), research uptake for health policymaking and practice is even lower, while little is known about the barriers to the translation of health evidence to policy and local implementation. We aimed to compile the current evidence on barriers to uptake of research in health policy and practice in LMICs using scoping review.MethodsThe scoping review followed the Preferred Reporting Items for Systematic Review and Meta-Analyses-extension for Scoping Reviews (PRISMA-ScR) and the Arksey and O'Malley framework. Both published evidence and grey literature on research uptake were systematically searched from major databases (PubMed, Cochrane Library, CINAHL (EBSCO), Global Health (Ovid)) and direct Google Scholar. Literature exploring barriers to uptake of research evidence in health policy and practice in LMICs were included and their key findings were synthesized using thematic areas to address the review question.ResultsA total of 4291 publications were retrieved in the initial search, of which 142 were included meeting the eligibility criteria. Overall, research uptake for policymaking and practice in LMICs was very low. The challenges to research uptake were related to lack of understanding of the local contexts, low political priority, poor stakeholder engagement and partnership, resource and capacity constraints, low system response for accountability and lack of communication and dissemination platforms.ConclusionImportant barriers to research uptake, mainly limited contextual understanding and low participation of key stakeholders and ownership, have been identified. Understanding the local research and policy context and participatory evidence production and dissemination may promote research uptake for policy and practice. Institutions that bridge the chasm between knowledge formation, evidence synthesis and translation may play critical role in the translation process.

Project description:BackgroundSurvey data that categorizes gender identity in binary terms and conflates sex and gender limits knowledge around the experience of gender minority populations, whose gender identity or expression does not align with the sex they were assigned at birth. In this review, we outline the existing survey research on the experience of a gender minority demographic for whom there is particularly limited data: adolescents and youth in low and middle-income countries (LMICs).MethodsThis paper is a scoping review of peer-reviewed articles, published in English, that use survey data to examine the experience of gender minority adolescents and youth in LMICs. We conducted a search on two major databases using key terms related to gender identity, adolescence and youth, and country and region. This search yielded 385 articles. Following a team-conducted review, we retained 33 articles for the final analysis.ResultsOur review shows that surveys with adolescents and youth in LMICs are increasingly including questions and taking sampling approaches that allow gender minority populations to be visible in survey data. Surveys that do so are largely focused in upper middle-income countries (n = 24), rather than lower middle-income or low-income countries, with South East Asia a notable sub-region of focus (n = 15). Sexual health, mental health, and violence are key topics of interest. Most of the surveys rely on some form of network-driven sampling focused on sexual and/or gender minorities (n = 22). The studies vary in how they ask about gender identity, both in terms of question formulation and the answer categories that are offered, as well as the extent to which they describe the questions in the article text.ConclusionsThis review reveals a growing body of work that provides important insights into the experiences of gender minority adolescents and youth in LMICs. More studies could integrate these approaches, but it must be done in a way that is thoughtful about cultural and political context. Given the relatively nascent nature of such research, we encourage scholars to continue providing details on methodology, including around participant recruitment and the development of gender identity questions. This information would be valuable for researchers seeking to better include gender minorities and their experiences in survey research, but who might be daunted methodologically.

Project description:IntroductionAs the number of people living in cities increases worldwide, particularly in low-income and middle-income countries (LMICs), urban health is a growing priority of public and global health. Rapid unplanned urbanisation in LMICs has exacerbated inequalities, putting the urban poor at increased risk of ill health due to difficult living conditions in cities. Collaboration with communities in research is a key strategy for addressing the challenges they face. The objective of this scoping review is, therefore, to identify factors that influence the participation of urban communities from LMICs in public and global health research.Methods and analysisWe will develop a search strategy with a health librarian to explore the following databases: MEDLINE, Embase, Web of Science, Cochrane, Global Health and CINAHL. We will use MeSH terms and keywords exploring the concepts of 'low-income and middle-income countries', 'community participation in research' and 'urban settings' to look at empirical research conducted in English or French. There will be no restriction in terms of dates of publication. Two independent reviewers will screen and select studies, first based on titles and abstracts, and then on full text. Two reviewers will extract data. We will summarise the results using tables and fuzzy cognitive mapping.Ethics and disseminationThis scoping review is part of a larger project to be approved by the University of Montréal's Research Ethics Committee for Science and Health in Montréal (Canada), and the Institutional Review Board of the James P Grant School of Public Health at BRAC University in Dhaka (Bangladesh). Results from the review will contribute to a participatory process seeking to combine scientific evidence with experiential knowledge of stakeholders in Dhaka to understand how to better collaborate with communities for research. The review could contribute to a shift toward research that is more inclusive and beneficial for communities.
