    Completeness of Reporting in Diet- and Nutrition-Related Randomized Controlled Trials and Systematic Reviews With Meta-Analysis:Protocol for 2 Independent Meta-Research Studies

    Get PDF
    Background: Journal articles describing randomized controlled trials (RCTs) and systematic reviews with meta-analysis of RCTs are not optimally reported and often miss crucial details. This poor reporting makes assessing these studies’ risk of bias or reproducing their results difficult. However, the reporting quality of diet- and nutrition-related RCTs and meta-analyses has not been explored. Objective: We aimed to assess the reporting completeness and identify the main reporting limitations of diet- and nutrition-related RCTs and meta-analyses of RCTs, estimate the frequency of reproducible research practices among these RCTs, and estimate the frequency of distorted presentation or spin among these meta-analyses. Methods: Two independent meta-research studies will be conducted using articles published in PubMed-indexed journals. The first will include a sample of diet- and nutrition-related RCTs; the second will include a sample of systematic reviews with meta-analysis of diet- and nutrition-related RCTs. A validated search strategy will be used to identify RCTs of nutritional interventions and an adapted strategy to identify meta-analyses in PubMed. We will search for RCTs and meta-analyses indexed in 1 calendar year and randomly select 100 RCTs (June 2021 to June 2022) and 100 meta-analyses (July 2021 to July 2022). Two reviewers will independently screen the titles and abstracts of records yielded by the searches, then read the full texts to confirm their eligibility. The general features of these published RCTs and meta-analyses will be extracted into a research electronic data capture database (REDCap; Vanderbilt University). The completeness of reporting of each RCT will be assessed using the items in the CONSORT (Consolidated Standards of Reporting Trials), its extensions, and the TIDieR (Template for Intervention Description and Replication) statements. Information about practices that promote research transparency and reproducibility, such as the publication of protocols and statistical analysis plans will be collected. There will be an assessment of the completeness of reporting of each meta-analysis using the items in the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) statement and collection of information about spin in the abstracts and full-texts. The results will be presented as descriptive statistics in diagrams or tables. These 2 meta-research studies are registered in the Open Science Framework. Results: The literature search for the first meta-research retrieved 20,030 records and 2182 were potentially eligible. The literature search for the second meta-research retrieved 10,918 records and 850 were potentially eligible. Among them, random samples of 100 RCTs and 100 meta-analyses were selected for data extraction. Data extraction is currently in progress, and completion is expected by the beginning of 2023. Conclusions: Our meta-research studies will summarize the main limitation on reporting completeness of nutrition- or diet-related RCTs and meta-analyses and provide comprehensive information regarding the particularities in the reporting of intervention studies in the nutrition field

    Protocol for a meta-research study of protocols for diet or nutrition-related trials published in indexed journals:general aspects of study design, rationale and reporting limitations

    Get PDF
    INTRODUCTION: The Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) reporting guideline establishes a minimum set of items to be reported in any randomised controlled trial (RCT) protocol. The Template for Intervention Description and Replication (TIDieR) reporting guideline was developed to improve the reporting of interventions in RCT protocols and results papers. Reporting completeness in protocols of diet or nutrition-related RCTs has not been systematically investigated. We aim to identify published protocols of diet or nutrition-related RCTs, assess their reporting completeness and identify the main reporting limitations remaining in this field. METHODS AND ANALYSIS: We will conduct a meta-research study of RCT protocols published in journals indexed in at least one of six selected databases between 2012 and 2022. We have run a search in PubMed, Embase, CINAHL, Web of Science, PsycINFO and Global Health using a search strategy designed to identify protocols of diet or nutrition-related RCTs. Two reviewers will independently screen the titles and abstracts of records yielded by the search in Rayyan. The full texts will then be read to confirm protocol eligibility. We will collect general study features (publication information, types of participants, interventions, comparators, outcomes and study design) of all eligible published protocols in this contemporary sample. We will assess reporting completeness in a randomly selected sample of them and identify their main reporting limitations. We will compare this subsample with the items in the SPIRIT and TIDieR statements. For all data collection, we will use data extraction forms in REDCap. This protocol is registered on the Open Science Framework (DOI: 10.17605/OSF.IO/YWEVS). ETHICS AND DISSEMINATION: This study will undertake a secondary analysis of published data and does not require ethical approval. The results will be disseminated through journals and conferences targeting stakeholders involved in nutrition research

    The decline in mortality from circulatory diseases in Brazil Disminución en la mortalidad por enfermedades cardiovasculares en Brasil

    No full text
    OBJECTIVES: Cardiovascular diseases are the leading cause of death in the world. Although mortality rates have declined gradually in developed countries, the scenario is less clear in developing countries. We describe the trends in cardiovascular mortality in Brazil over 24 years and investigate differences according to groups of diseases, sociopolitical region, gender, and age. METHODS: We retrieved official data on mortality and population estimates to calculate standardized mortality rates in six age strata and in the five political regions from 1980 through 2003. The negative binomial distribution model was used to estimate trends for mortality separately for each gender, age group, and geopolitical region during this period. RESULTS: Total cardiovascular standardized mortality rates decreased consistently over 24 years, from 287.3 to 161.9 per 100000 inhabitants, with a mean annual decrease of 3.9%. Reductions in cardiovascular standardized mortality rates were detected in all strata and for all groups of diseases, with stroke exhibiting the largest average decline, from 95.2 to 52.6 per 100000 inhabitants (mean 4.0% per year), followed by coronary disease, from 80.3 to 49.2 per 100000 inhabitants (3.6% per year); the decrease was especially marked in the most developed regions. CONCLUSIONS: Cardiovascular disease standardized mortality rates consistently decreased in Brazil during the study period. The reduction is apparently related to indices of increasing social development. Despite these encouraging findings, a gradual increase in the deaths from cardiovascular disease is expected in the next decades, and additional efforts in prevention are needed.OBJETIVOS: Las enfermedades cardiovasculares constituyen la primera causa de muerte en el mundo. Aunque las tasas de mortalidad han disminuido gradualmente en los países desarrollados, el escenario es menos claro en los países en desarrollo. Se describen las tendencias de la mortalidad por enfermedades cardiovasculares en Brasil durante 24 años y se analizan las diferencias según el grupo de enfermedades, la región, el sexo y la edad. MÉTODOS: Se tomaron los datos oficiales de mortalidad y los estimados de población para calcular las tasas de mortalidad estandarizadas en seis grupos de edad y cinco regiones sociopolíticas entre 1980 y 2003. Se empleó el modelo de distribución binomial negativa para estimar las tendencias de la mortalidad por sexo, grupo de edad y región geopolítica en ese período. RESULTADOS: Las tasas de mortalidad estandarizadas totales por enfermedades cardiovasculares disminuyeron sistemáticamente en los 24 años, de 287,3 a 161,9 por 100000 habitantes, con un decrecimiento anual promedio de 3,9%. Se encontraron decrecimientos en las tasas de mortalidad estandarizadas en todos los grupos de edad y de enfermedades. Los accidentes cerebrovasculares presentaron la mayor reducción (de 95,2 a 52,6 por 100000 habitantes; media anual: 4,0%), seguidos de la enfermedad coronaria (de 80,3 a 49,2 por 100000 habitantes; media anual: 3,6%). La disminución fue más acentuada en las regiones de mayor desarrollo. CONCLUSIONES: Las tasas de mortalidad estandarizadas por enfermedades cardiovasculares disminuyeron sistemáticamente en Brasil en el período estudiado. Aparentemente, esta reducción está relacionada con los índices de aumento en el desarrollo social. A pesar de estos alentadores resultados, se espera un aumento gradual en las muertes por enfermedades cardiovasculares en las próximas décadas, por lo que se requiere un esfuerzo preventivo adicional

    Instruments and indicators for assessing organisational food environments: a scoping review protocol

    No full text
    Introduction Many studies have explored the food environment to characterise it and understand its role in food practices. Assessment of the organisational food environment can contribute to the development of more effective interventions to promote adequate and healthy eating. However, few instruments and indicators have been developed and validated for assessing this type of setting. The systematisation of those can be useful to support the planning of future assessments and the development of wide-ranging instruments. This study aims to conduct a scoping review to systematise evidence on instruments and indicators for assessing organisational food environments.Methods and analysis This scoping review was planned according to the methodological framework for scoping reviews proposed by Arksey and O’Malley and subsequently enhanced by Levac et al. For the report of the review, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses—Extension for Scoping Reviews (PRISMA-ScR) checklist and guidelines will be used. The search will be conducted using PubMed, Embase, Web of Science, PsycINFO, Scopus and Google Scholar databases. The studies to be included were required to have been published in peer-reviewed journals since January 2005. No geographical, population or language restrictions will be applied given the desired breadth of the review. Two researchers will select the articles and extract the data independently. The conceptual model proposed by Castro and Canella will guide the data extraction and analysis. The results will be presented with narrative synthesis for the extracted data accompanying the tabulated and charted results.Ethics and dissemination This study is based on the analysis of published scientific literature and did not involve patients, medical research, or any type of personal information; therefore, no ethical approval was obtained for this study. The results of this scoping review will be submitted for publication in an international peer-reviewed journal, preferably open access

    The Cost-Effectiveness of Homecare Services for Adults and Older Adults: A Systematic Review

    No full text
    This study provides an overview of the literature on the cost-effectiveness of homecare services compared to in-hospital care for adults and older adults. A systematic review was performed using Medline, Embase, Scopus, Web of Science, CINAHL and CENTRAL databases from inception to April 2022. The inclusion criteria were as follows: (i) (older) adults; (ii) homecare as an intervention; (iii) hospital care as a comparison; (iv) a full economic evaluation examining both costs and consequences; and (v) economic evaluations arising from randomized controlled trials (RCTs). Two independent reviewers selected the studies, extracted data and assessed study quality. Of the 14 studies identified, homecare, when compared to hospital care, was cost-saving in seven studies, cost-effective in two and more effective in one. The evidence suggests that homecare interventions are likely to be cost-saving and as effective as hospital. However, the included studies differ regarding the methods used, the types of costs and the patient populations of interest. In addition, methodological limitations were identified in some studies. Definitive conclusions are limited and highlight the need for better standardization of economic evaluations in this area. Further economic evaluations arising from well-designed RCTs would allow healthcare decision-makers to feel more confident in considering homecare interventions

    Intimate partner violence and breastfeeding practices: a systematic review of observational studies

    No full text
    Objective: To review the association between intimate partner violence and breastfeeding practices in the literature. Data sources: The search was carried out in five databases, including MEDLINE, LILACS, SCOPUS, PsycoINFO, and Science Direct. The search strategy was carried out in February 2017. The authors included original studies with observational design, which investigated forms of intimate partner violence (including emotional, physical, and/or sexual) and breastfeeding practices. The quality of the studies was assessed based on the bias susceptibility through criteria specifically developed for this review. Summary of data: The study included 12 original articles (10 cross-sectional, one case-control, and one cohort study) carried out in different countries. The forms of intimate partner violence observed were emotional, physical, and/or sexual. Breastfeeding was investigated by different tools and only assessed children between 2 days and 6 months of life. Of the 12 studies included in this review, eight found a lower breastfeeding intention, breastfeeding initiation, and exclusive breastfeeding during the first six months of the child's life, and a higher likelihood of early termination of exclusive breastfeeding among women living at home where violence was present. The quality varied between the studies and six were classified as having low bias susceptibility based on the assessed items. Conclusions: Intimate partner violence is associated with inadequate breastfeeding practices of children aged 2 days to 6 months of life. Resumo: Objetivo: Revisar na literatura a associação da violência entre parceiros íntimos e as práticas de aleitamento materno. Fontes dos dados: Foram utilizadas para as buscas cinco bases de dados, incluindo o MEDLINE, LILACS, SCOPUS, PsycoINFO e Science Direct. A estratégia de busca foi realizada em fevereiro de 2017. Foram incluídos estudos originais com desenho observacional, os quais investigaram formas de violência entre parceiros íntimos: emocional, física e/ou sexual e as práticas de aleitamento materno. A qualidade dos estudos foi avaliada a partir da susceptibilidade a vieses por critérios especificamente desenvolvidos para esta revisão. Síntese dos dados: Foram incluídos 12 artigos originais (10 seccionais, 1 caso-controle e 1 coorte) realizados em diferentes países. As formas de violência entre parceiros íntimos observadas foram emocional, física e/ou sexual. O aleitamento materno investigado nos estudos se fez por diferentes instrumentos e avaliaram apenas crianças entre dois dias e seis meses de vida. Dos doze estudos incluídos nesta revisão, oito encontraram menor chance de intenção de amamentar, menor chance de iniciação ao aleitamento materno e de amamentação exclusiva durante os primeiros seis meses de vida da criança e maior probabilidade de interrupção precoce do aleitamento materno exclusivo entre as mulheres que viviam em domicílios onde a violência estava presente. A qualidade variou entre os estudos e seis foram classificados apresentando baixa suscetibilidade ao viés a partir dos itens julgados. Conclusões: A violência entre parceiros íntimos está relacionada às práticas inadequadas de aleitamento materno de crianças entre dois dias e seis meses de vida.
