- ItemEpidemiology of lower respiratory infection and pneumonia in South Africa (1997 – 2015) : a systematic review protocol(BMJ Publishing Group, 2016) Roomaney, Rifqah A.; Pillay-van Wyk, Victoria; Awotiwon, Oluwatoyin F.; Dhansay, Ali; Groenewald, Pam; Joubert, Jane D.; Nglazi, Mweete D.; Nicol, Edward; Bradshaw, DebbieIntroduction: Lower respiratory infections (LRIs) and pneumonia are among the leading causes of death worldwide, especially in children aged under 5 years, and these patterns are reflected in the South African population. Local epidemiological data for LRIs and pneumonia are required to inform the Second National Burden of Disease Study underway in South Africa. The aim of this systematic review is to identify published studies reporting the prevalence, incidence, case fatality, duration or severity of LRI and pneumonia in adults and children in South Africa. Methods and analysis: Electronic database searches will be conducted to obtain studies reporting on the prevalence, incidence, case fatality, duration and severity of LRI and pneumonia in South Africa between January 1997 and December 2015. Studies that are assessed to have moderate or low risk of bias will be included in a meta-analysis, if appropriate. Where meta-analysis is not possible, the articles will be described narratively. Subgroup analysis (eg, age groups) will also be conducted where enough information is available. Ethics and dissemination: This systematic review will only include published data with no linked patientlevel information; thus, no ethics approval is required. The findings will be used to calculate the burden of disease attributed to LRI and pneumonia in South Africa and will highlight the type of epidemiological data available in the country. The article will be disseminated in a peer-reviewed publication.
- ItemEpidemiology of major depressive disorder in South Africa (1997 – 2015): a systematic review protocol(BMJ Publishing Group, 2016) Nglazi, Mweete D.; Joubert, Jane D.; Stein, Dan J.; Lund, Crick; Wiysonge, Charles S.; Vos, Theo; Pillay-van Wyk, Victoria; Roomaney, Rifqah A.; Muhwava, Lorrein S.; Bradshaw, DebbieENGLISH SUMMARY : Introduction: Major depressive disorder (MDD) is a leading cause of disease and disability globally and in South Africa. Epidemiological data for MDD are essential to estimate the overall disease burden in a country. The objective of the systematic review is to examine the evidence base for prevalence, incidence, remission, duration, severity, case fatality and excess mortality of MDD in South Africa from 1997 to 2015. Methods and analysis: We will perform electronic searches in PubMed, PsycINFO, Scopus and other bibliographical databases. Articles published between January 1997 and December 2015 will be eligible for inclusion in this review. The primary outcomes will be prevalence, incidence, remission, duration, severity, case fatality and excess mortality of MDD. The secondary outcomes will be risk factors and selected populations for MDD. If appropriate, a meta-analysis will be performed. If a meta-analysis is not possible, the review findings will be presented narratively and in tables. Subgroup analyses will be conducted with subgroups defined by population group, rural/urban settings and study designs, if sufficient data are available.
- ItemThe prevalence of type 2 diabetes in South Africa : a systematic review protocol(BMJ Publishing Group, 2018-06) Pheiffer, Carmen; Pillay-Van Wyk, Victoria; Joubert, Jane D.; Levitt, Naomi; Nglazi, Mweete D.; Bradshaw, DebbieIntroduction Type 2 diabetes mellitus is a major source of morbidity and mortality in South Africa, spurred by increased urbanisation and unhealthy lifestyle factors. Local epidemiological data are required to inform health planning and policy. The purpose of this systematic review is to identify, collate and synthesise all studies reporting the prevalence of diabetes in South Africa. A secondary aim is to report the prevalence of impaired glucose tolerance and impaired fasting glucose, conditions which are associated with an increased risk of progression to overt diabetes, and the prevalence of undiagnosed diabetes. Methods and analysis Multiple databases will be searched for diabetes prevalence studies conducted in South Africa between 1997 and 2018. Two authors will independently select studies that meet the inclusion criteria, extract data and appraise studies using a risk of bias tool for prevalence studies. Studies with low or moderate risk of bias will be included. Sources of heterogeneity will be explored using subgroup analysis. Ethics and dissemination The systematic review does not require ethics clearance since published studies with non-identifiable data will be used. This review will provide best estimates to inform the Second National Burden of Disease study which can guide health and policy planning.
