Project description:Vitamin D is an essential nutrient. Its role in calcium and phosphorous metabolism, and in the development and maintenance of a healthy skeleton is well documented. In addition, there is some evidence for vitamin D decreasing total mortality and cancer mortality modestly, but not cancer incidence. Vitamin D is unique, as both diet and sun induced production in skin are sources to this vitamin. Individual vitamin D status is thus a sum of both sun exposure and dietary intakes. The discovery of vitamin D receptors and the activation of biological active vitamin D in numerous tissues and organs in the body has given support to hypothesis on vitamin D having extra-skeletal functions. The scientific literature on vitamin D and several health outcomes is high in numbers and has been increasing exponentially the last two decades. However, despite this large body of scientific publications and improvement in study quality, vitamin D supplementation has not shown to give additional health benefits when status is in sufficient range (i.e. circulating 25 hydroxyvitamin D >50 nmol/L). Well-designed studies on insufficient or deficient individuals are lacking. The totality of evidence does not support that increased intake of vitamin D beyond current recommendation will have additional beneficial health effects.

Project description:BACKGROUND: It is important that healthcare provided in crisis settings is based on the best available research evidence. We reviewed guidelines for child and perinatal health care in crisis situations to determine whether they were based on research evidence, whether Cochrane systematic reviews were available in the clinical areas addressed by these guidelines and whether summaries of these reviews were provided in Evidence Aid. METHODS: Broad internet searches were undertaken to identify relevant guidelines. Guidelines were appraised using AGREE and the clinical areas that were relevant to perinatal or child health were extracted. We searched The Cochrane Database of Systematic Reviews to identify potentially relevant reviews. For each review we determined how many trials were included, and how many were conducted in resource-limited settings. RESULTS: Six guidelines met selection criteria. None of the included guidelines were clearly based on research evidence. 198 Cochrane reviews were potentially relevant to the guidelines. These reviews predominantly addressed nutrient supplementation, breastfeeding, malaria, maternal hypertension, premature labour and prevention of HIV transmission. Most reviews included studies from developing settings. However for large portions of the guidelines, particularly health services delivery, there were no relevant reviews. Only 18 (9.1%) reviews have summaries in Evidence Aid. CONCLUSIONS: We did not identify any evidence-based guidelines for perinatal and child health care in disaster settings. We found many Cochrane reviews that could contribute to the evidence-base supporting future guidelines. However there are important issues to be addressed in terms of the relevance of the available reviews and increasing the number of reviews addressing health care delivery.

Project description:Consumption of legumes and pulses is associated with various health outcomes. Therefore, when updating the Nordic Nutrition Recommendations (NNR), summarizing the best available evidence on key health outcomes regarded as relevant for the Nordic and Baltics related to the consumption of legumes was essential. The aim of this scoping review was to evaluate the updated evidence on the effect of the consumption of legumes and pulses on various health outcomes, as well as their dose-response relationship in updated systematic reviews and meta-analyses. The scoping review is built on a de novo systematic review published in 2023 and additional searches on the consumption of legumes and pulses and its various health outcomes, including cardiovascular disease (CVD), cancer, type 2 diabetes, and obesity. Current available evidence shows that the consumption of legumes and pulses is associated with a lower risk of several cancers (evidence: low-moderate), and lower all-cause mortality (evidence: moderate). The associations with CVDs are neutral or inverse, with studies generally showing favourable changes in biomarkers for CVDs. Legume consumption is associated with a lower risk of obesity (evidence: low). For type 2 diabetes, no association was found with incidence, but trials on consumption of legumes and pulses and biomarkers generally indicated protective effects. Overall, the current evidence supports dietary recommendations to increase the consumption of legumes and pulses.

Project description:BackgroundNuts and seeds have been part of diets in most of the world for millenniums, and they have also been consumed in the Nordic and Baltic countries for centuries. Consumption of nuts and seeds is linked with various health outcomes. Therefore, when updating the Nordic Nutrition Recommendations (NNR), summarizing the best evidence on key health outcomes from the consumption of nuts and seeds is essential.ObjectivesThis study aims to evaluate the updated evidence on the consumption of nuts and seeds and health outcomes regarded relevant for the Nordic and Baltic countries, as well as their dose-response relationship presented in updated systematic reviews and meta-analyses.MethodThe scoping review is built on a de novo systematic review and an umbrella review published in 2022 on the consumption of nuts and seeds and its various health outcomes, including cardiovascular disease and diabetes.ResultsIntake of nuts and seeds is associated with a lower risk of cardiovascular diseases, with evidence assessed as probable. This conclusion is mirrored by evidence from trials on biomarkers for chronic diseases. An intake of a serving of nuts of 28-30 g/day compared to not eating nuts is estimated to translate into approximately 20% relative reduction in the risks of cardiovascular disease and premature deaths. For cancers, consumption of a serving of nuts is inversely associated with cancer mortality. However, for type 2 diabetes, there are mixed and inconclusive results. Additionally, there are inverse associations between nut consumption and respiratory and infectious disease mortality. Allergies for nuts are seen among 1-2% of the population.ConclusionOverall, the current evidence supports dietary recommendations to increase nut consumption to a serving of nuts and seeds per day for people without allergies to these foods.

Project description:Antioxidants are a collection of substances that may prevent or delay the oxidation of cellular components. The antioxidant defense system includes both endogenously produced antioxidants and dietary antioxidants. The consumption of dietary antioxidants has long been speculated to be important for the defense against cellular oxidation, inflammation, and other disease-related processes. In addition to the well-known dietary antioxidants, such as vitamin C, vitamin E, β-carotene, and selenium, whole plants and plant-products contain numerous compounds, called phytochemicals, with antioxidant properties. These phytochemicals are potentially important modulators of oxidative stress and have been linked to health beneficial effects. However, the mechanisms underlying these potential health beneficial effects are not well understood. Foods containing high levels of phytochemicals with antioxidant properties include berries, fruits, vegetables, whole grains, and nuts and seeds. The aim of this scoping review is to describe the evidence of the role of specific antioxidants and phytochemicals, but not foods rich in these substances, for health outcomes. Based on a literature search from 2011 to March 2022, we identified eight meta-analyses related to the current topic. These studies include evidence of the effect of resveratrol (present mainly in berries, grapes, and peanuts) on health outcomes related to cardiometabolic risk, blood pressure, obesity, oxidative stress, adipokines, inflammation, and bone quality. In summary, resveratrol did elicit several health beneficial effects. However, the magnitude of effects was low, and whether the effects are related to the redox properties of resveratrol is not known. Even though there is a large body of evidence linking a plant-based diet rich in antioxidants and phytochemicals to beneficial health effects, the role of specific antioxidants and phytochemicals is still unclear.

Project description:BackgroundFragile and conflict-affected settings (FCAS) have a strong need to improve the capacity of local health workers to conduct health research in order to improve health policy and health outcomes. Health research capacity building (HRCB) programmes are ideal to equip health workers with the needed skills and knowledge to design and lead health-related research initiatives. The study aimed to review the characteristics of HRCB studies in FCASs in order to identify their strengths and weaknesses, and to recommend future directions for the field.MethodsWe conducted a scoping review and searched four databases for peer-reviewed articles that reported an HRCB initiative targeting health workers in a FCAS and published after 2010. Commentaries and editorials, cross-sectional studies, presentations, and interventions that did not have a capacity building component were excluded. Data on bibliographies of the studies and HRCB interventions and their outcomes were extracted. A descriptive approach was used to report the data, and a thematic approach was used to analyse the qualitative data.ResultsOut of 8822 articles, a total of 20 were included based on the eligibility criteria. Most of the initiatives centred around topics of health research methodology (70%), targeted an individual-level capacity building angle (95%), and were delivered in university or hospital settings (75%). Ten themes were identified and grouped into three categories. Significant challenges revolved around the lack of local research culture, shortages in logistic capability, interpersonal difficulties, and limited assessment and evaluation of HRCB programmes. Strengths of HRCB interventions included being locally driven, incorporating interactive pedagogies, and promoting multidisciplinary and holistic training. Common recommendations covered by the studies included opportunities to improve the content, logistics, and overarching structural components of HRCB initiatives.ConclusionOur findings have important implications on health research policy and related capacity building efforts. Importantly, FCASs should prioritize (1) funding HRCB efforts, (2) strengthening equitable international, regional, and national partnerships, (3) delivering locally led HRCB programmes, (4) ensuring long-term evaluations and implementing programmes at multiple levels of the healthcare system, and (5) adopting engaging and interactive approaches.

Project description:BackgroundChild health indicators have substantially improved across the last decade, yet Afghanistan has among the highest child stunting and malnutrition rates in Asia. Multisectoral approaches were recently introduced but evidence for this approach to improve support for and implementation of child nutrition programmes is limited compared to other countries.MethodsWe reviewed policy and programme data to identify best practices and gaps surrounding child malnutrition in Afghanistan. We conducted a scoping review using broad search categories and approaches, including database and website searches, reference hand-searches, purposive policy and programme document request, and key informant interviews. Inclusion and exclusion criteria were developed iteratively, with abstracts and documents assessed against the final criteria. We abstracted documents systematically and summarised and synthesised content to generate the main findings.ResultsWe included 18 policies and strategies, 45 data sources and reports, and 20 intervention evaluations. Movement towards multisectoral efforts to address malnutrition at the policy level has started; however, integrated nutrition-specific and nutrition-sensitive interventions are not yet uniformly delivered at the community level. Many data sources capturing nutrition, food security and WASH (water, sanitation and hygiene) indicators are available but indicator definitions are not standardised and there are few longitudinal nutrition surveys. Political will to improve household nutrition status has shown increased government and donor investments in nutrition-sensitive and nutrition-specific programmes through combined small- and large-scale interventions between 2004 and 2013; however, evidence for interventions that effectively decrease stunting prevalence is limited.ConclusionsThis review shows a breadth of nutrition programme, policy and data in Afghanistan. Multisector approaches faced challenges of reaching sufficient coverage as they often included a package of food security, livelihoods and health interventions but were each implemented independently. Further implementation evidence is needed to aid policy and programmes on effective integration of nutrition, food security and WASH in Afghanistan.

Project description:Background: Playgrounds provide children with many sensory, motor, and socioemotional experiences that are critical to child development. Unfortunately, playgrounds also represent an environment where children with disabilities experience barriers to accessing play. Structures and materials that are prominently found in almost all playground designs (e.g., swings, slides, sand) can present as obstacles for many children with disabilities to engage in independent play. Aims: This scoping review engaged in the empirical literature to address the research question, "What are the evidence-informed recommendations for designing inclusive playgrounds to enable participation for children with disabilities?" Consideration was given not only to the physical design of playgrounds, but also the playgrounds' surrounding built and social environments. Methods: A systematic search of Medline, PsycINFO, CINAHL, EMBase, ERIC and Scopus was conducted. Only peer-reviewed literature published in English between January 1990 and January 2021, with a primary focus on inclusive playground structure design related to any type of disability were included. Data extraction included the study author(s), year of publication, country of origin, purpose, disability types considered, methods, sample characteristics and key findings. Key findings were synthesized into evidence-informed recommendations, which were later collated, using inductive content analysis, into five broader thematically congruent groups. Results: Thirty-five studies were included using case study (n = 17); observational (n = 6); survey (n = 5); experimental (n = 4); and multiple study (n = 3) designs. Thirteen evidence-based recommendations and one promising practice were categorized into five broad playground elements: entry points; surfacing and paths; features to foster inclusive play; staffing/supervision; and design process. Conclusion: These recommendations build upon previous design-based best-practices that focused exclusively on the physical design of the playground. Our recommendations have implications for how future playgrounds should be designed to maximize usability and inclusiveness and the overall playground experiences for children with disabilities.
