Mapping evidence on the burden and distribution of childhood obesity in sub-Saharan Africa: a scoping review protocol.

ABSTRACT: BACKGROUND:Obesity in childhood is associated with adverse health outcomes and complications throughout the life-span of a child. Available evidence suggests a dramatic increase in childhood obesity in sub-Saharan Africa (SSA) over the past two decades. The health risks associated with obesity/overweight are particularly problematic in children due to the potential for long-term health concerns. The researchers propose to conduct a systematic scoping review to map evidence on the burden and distribution of childhood obesity in SSA. METHODS:The study will be guided by the scoping review framework proposed by Arksey and O'Malley. A comprehensive literature search will be performed in the following electronic databases: PubMed, Web of Science, African Index Medicus, and CINAHL with full text via EBSCOhost platform. Primary studies both published in peer-reviewed journals and gray literature such as unpublished studies, thesis, and studies in press addressing the research topic will be included. One reviewer will conduct title screening, and the results will be exported to Mendeley Desktop library. Two independent reviewers will perform both abstract and full article screening in parallel as well as data extraction from eligible studies. The Preferred Reporting Items for Systematic Reviews and Meta-analysis: Extension for Scoping Review (PRISMA-ScR) will be utilized to present the study findings of the proposed scoping review. NVivo version 11.0 will be used to extract the relevant outcomes from the included studies, a content thematic analysis performed, and the results reported using a narrative approach. The Mixed Method Quality Appraisal Tool Version 2018 will be used to assess the methodological quality of all included studies. DISCUSSION:We anticipate that the proposed study will contribute to the existing body of knowledge on childhood obesity, identify gaps in knowledge on the topic, inform future research direction, and provide evidence-based information to strengthen health systems and policies on childhood obesity towards achieving the WHO global target of halting the rise in obesity by 2025.

Project description:BackgroundDepression is one of the most prevalent mental disorders among an estimated 25.6 million people living with HIV (PLHIV) in sub-Saharan Africa (SSA). The depression rate is higher in HIV-seropositive men who have sex with men (MSM) regardless of their sexual orientation, identity or romantic attraction. This is due to various types of stigma including HIV-related stigma, social stigma, self-stigma and mental health stigma. Opportunistic infections, unemployment, poverty and food insecurity also predispose HIV-seropositive MSM to depression. Moreover, depression in heterosexual and sexual minority groups challenges and additionally burdens SSA health care systems due to inadequate economic developments, lack of mental health professionals who specialise in the treatment of depression, few MSM-centred facilities, inadequate mental health infrastructure (hospitals and clinics) and complimentary resources. Although studies have highlighted links between mental health disorder, an HIV diagnosis and sexual minority groups, there is limited research that focusses on depression and its causal factors in MSM living with HIV in SSA. Hence, the relevance of conducting this scoping review.MethodsA scoping review guided by Arksey and O'Malley's framework, the enhancements and recommendations of Levac, Colquhoun and O'Brien, Daudt and associates and the 2015 Johanna Briggs Institute's guidelines will be conducted. Systematic electronic searches of databases and search engines such as Google, Google Scholar, CINAHL (EBSCOhost), MEDLINE (Ovid), and PsycInfo (Ovid) will be conducted to attain published peer-reviewed articles of all study designs. Grey literature will be sourced from media and conference abstracts and reports, governmental reports and unpublished dissertations and theses. Additionally, websites of humanitarian organisations and other relevant departmental websites will also be searched. Literature published between 2010 and 2020 that meets the review's inclusion criteria, research question and sub-question will be included in this review. All the retrieved literature will be exported to an Endnote X9.2 library after duplicates have been removed.DiscussionWe anticipate mapping relevant literature on depression and the causal factors in HIV-seropositive MSM living in SSA. Once analysed and summarised, the data will be useful in identifying literature gaps, informing systematic reviews and future research. The findings could also assist in depression and sexuality dialogues, and awareness campaigns that address mental health issues, stigma and discrimination among this key population living in SSA.

Project description:Background Cancer remains a major public health problem, especially in Sub-Saharan Africa (SSA) where the provision of health care is poor. This scoping review mapped evidence in the literature regarding the burden of cervical, breast and prostate cancers in SSA. Methods We conducted this scoping review using the Arksey and O'Malley framework, with five steps: identifying the research question; searching for relevant studies; selecting studies; charting the data; and collating, summarizing, and reporting the data. We performed all the steps independently and resolved disagreements through discussion. We used Endnote software to manage references and the Rayyan software to screen studies. Results We found 138 studies that met our inclusion criteria from 2,751 studies identified through the electronic databases. The majority were retrospective studies of mostly registries and patient files (n = 77, 55.8%), followed by cross-sectional studies (n = 51, 36.9%). We included studies published from 1990 to 2021, with a sharp increase from 2010 to 2021. The quality of studies was overall satisfactory. Most studies were done in South Africa (n = 20) and Nigeria (n = 17). The majority were on cervical cancer (n = 93, 67.4%), followed by breast cancer (67, 48.6%) and the least were on prostate cancer (48, 34.8%). Concerning the burden of cancer, most reported prevalence and incidence. We also found a few studies investigating mortality, disability-adjusted life years (DALYs), and years of life lost (YLL). Conclusions We found many retrospective record review cross-sectional studies, mainly in South Africa and Nigeria, reporting the prevalence and incidence of cervical, breast and prostate cancer in SSA. There were a few systematic and scoping reviews. There is a scarcity of cervical, breast and prostate cancer burden studies in several SSA countries. The findings in this study can inform policy on improving the public health systems and therefore reduce cancer incidence and mortality in SSA.

Project description:Background: Sub-Saharan Africa (SSA) homes most of the people living with HIV/AIDS in the world. Adolescents/young people are a vulnerable population and at high risk of HIV infection. Identifying and bridging the research gaps on the disclosure of HIV-positive status among adolescents, particularly to their sexual partners, is essential to inform appropriate policy planning and implementation towards preventing HIV transmission. This study will aim to explore literature and describe the evidence on HIV-positive status disclosure among adolescents in SSA.Methods: The framework provided by Arksey and O'Malley's framework and improved by Levac and colleagues will be used to conduct a scoping review. A keyword search for relevant literature presenting evidence on HIV-positive status disclosure among adolescents in SSA will be conducted in CINAHL, PubMed, Science Direct, Google Scholar, and SCOPUS. Date limitations will be removed, but Boolean terms "AND" and "OR" as well as Medical Subject Headings terms will be included where possible and syntax modified to suit the database during the search. Additional relevant articles will be sought from the reference lists of all included studies using a snowballing method. Two reviewers will independently screen the articles at the abstract and full-text screening phases in order to reduce bias and improve the reliability of this study's findings. A tabular form will be developed using Microsoft Word and piloted for data extraction. Thematic content analysis will be conducted, and a narrative summary of all relevant outcomes reported. Quality appraisal of the included studies for this proposed study will be performed utilizing the recent mixed methods appraisal tool.Discussion: The evidence produced by this review may help inform policy and strategies to reduce the incidence of HIV infection among adolescents and improve social support for adolescents living with HIV/AIDS in SSA. It may also reveal literature gaps to guide future researches to further inform HIV policies for adolescents in SSA. Platforms such as peer review journals, policy briefs, and conferences will be used to disseminate this study's findings.

Project description:IntroductionInfections of the central nervous system are a considerable basis of mortality in people living with HIV, with progression to cryptococcal meningitis documented at around 15% of HIV-associated mortality globally, with nearly three-quarters occurring in the sub-Saharan Africa. Discoveries from previous studies prelude to the mortality of cryptococcal antigen positive, which persisted to be elevated than in cryptococcal antigen negative persons. One feasible interpretation of this could be due to undiagnosed cryptococcus. Laboratory investigations identify cryptococcal disease prior to cryptococcal meningitis progression. Point-of-care testing has high sensitivity and specificity as seen with the cryptococcal antigen lateral flow assay screening to expedite treatment. The aim of the study is to map and translate evidence on cryptococcal antigen infection among HIV-infected persons in sub-Saharan Africa.MethodologyThe proposed scoping review will be conducted using guidelines proposed by Arksey and O'Malley methodological framework and Levac et al. advanced method. It will be guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analysis for Scoping Reviews. A comprehensive literature search of studies published from the first relevant publication to 2022 will be conducted on multiple electronic databases. Additional sources (grey literature) will also be searched. The search strategy will be generated and implemented by the principal investigator with assistance from a subject specialist, and an information specialist. Two reviewers will screen eligible studies. The screening will be guided by an inclusion and exclusion criteria. The mixed methods appraisal tool version 2018 will be used to appraise the quality of the empirical studies.DiscussionThe proposed scoping review will map and translate evidence on cryptococcal antigen infection among HIV-infected persons in sub-Saharan Africa. Synthesising and sharing recent evidence in this area has potential to help guide future research and interventions aimed at improving the management of cryptococcal antigen infection among HIV-infected persons in sub-Saharan Africa and other high HIV- burdened settings.

Project description:Cervical cancer (CC) is the most common viral infection of the reproductive tract and in Sub-Saharan Africa (SSA), its morbidity and mortality rates are high. The aim of this review was to map evidence on CC management in SSA. The scoping review was conducted in accordance with Arksey and O'Malley's scoping review framework. The review included studies on different aspects of CC management. The review was also done following the steps and guidelines outlined in the PRISMA-Extension for Scoping Reviews (PRISMA-ScR) checklist. The following databases were searched: PubMed, EBSCOhost, Scopus and Cochrane Database of Systematic Review. A total of 1121 studies were retrieved and 49 which were eligible for data extraction were included in the review. The studies were classifiable in 5 groups: 14 (28.57%) were on barriers to CC screening, 10 (20.41%) on factors associated with late-stage presentation at diagnosis, 11 (22.45%) on status of radiotherapy, 4 (8.20%) on status of chemotherapy and 10 (20.41%) on factors associated with high HPV coverage. High HPV vaccine coverage can be achieved using the class school-based strategy with opt-out consent form process. Barriers to CC screening uptake included lack of knowledge and awareness and unavailability of screening services. The reasons for late-stage presentation at diagnosis were unavailability of screening services, delaying whilst using complementary and alternative medicines and poor referral systems. The challenges in chemotherapy included unavailability and affordability, low survival rates, treatment interruption due to stock-outs as well as late presentation. Major challenges on radiotherapy were unavailability of radiotherapy, treatment interruption due to financial constraints, and machine breakdown and low quality of life. A gap in understanding the status of CC management in SSA has been revealed by the study implying that, without full knowledge of the extent of CC management, the challenges and opportunities, it will be difficult to reduce infection, improve treatment and palliative care. Research projects assessing knowledge, attitude and practice of those in immediate care of girls at vaccination age, situational analysis with health professionals and views of patients themselves is important to guide CC management practice.

Project description:BACKGROUND:In sub-Saharan Africa (SSA), malnutrition remains a major public health challenge, particularly among children under 5 years of age. Despite nutritional screening tools being developed and available to detect early malnutrition in under five-year-old children, malnutrition continues to be a health concern. However, the level of evidence on nutritional screening tools for predicting early malnutrition at the community level in a high disease burden setting is unclear. The objective of this scoping review is to systematically map the evidence on malnutrition screening tools for children under 5 years in sub-Saharan Africa (SSA) and to identify knowledge gaps. METHODS:The proposed study will be guided by an improved Arksey and O'Malley's framework, Levac et al. 2010 recommendations, and the 2015 Joanna Briggs Institute guidelines. We will conduct a systematic search of relevant imperial sources of evidence from the following databases: CINAHL with full text, Academic search complete via EBSCOhost, Google Scholar, Science Direct, and PubMed. We will search for grey literature from the following humanitarian and aid organization websites: World Health Organization (WHO), The United Nations International Children's Emergency Fund (UNICEF), and governmental departments. Following the database searches and title screening, eligible sources of evidence will be exported to an EndNote X9 reference library. Thereafter, duplicate articles will be removed in preparation for abstract and full article screenings. Data from the included sources of evidence will be extracted, and the emerging themes will be analyzed. The relationship between the emerging themes and the research questions will be critically examined. The quality of the included sources of evidence will be determined by using the Mixed Method Appraisal Tool (MMAT) version 2018. The search results will be presented in adapted Preferred Reporting Items for Systematic Reviews and Meta-Analysis: Extension for Scoping Reviews chart (PRISMA-ScR). DISCUSSION:We anticipate finding relevant literature on malnutrition screening tools for children under 5 years in SSA. This study is likely to reveal research gaps, which could guide future research on malnutrition screening tools.
