    Abstract:
    INTRODUCTION: Cardiovascular disease (CVD) is the leading cause of death globally and disproportionately affects low-income and middle-income countries. Dyslipidaemia is an important modifiable risk factor for CVD. There are important knowledge gaps regarding the population levels of lipid variables and frequency of non-optimal levels in populations within Africa. We propose to conduct a systematic review to determine the prevalence and occurrence of dyslipidaemia in adult populations within countries in Africa. METHODS AND ANALYSIS: We will perform a comprehensive search to identify all possible published and unpublished studies on the prevalence or incidence of dyslipidaemia in Africa reported from 1 January 1980, without language restriction. The scientific databases PubMed MEDLINE, EMBASE and ISI Web of Science will be searched, as well as Grey literature. Following study selection, full-text papers acquisition, and data extraction and synthesis, we will appraise the quality of studies and risk of bias, and assess heterogeneity. Prevalence/incidence data will be summarised by country and geographic regions and a meta-analysis will be conducted for variables defined identically across studies. Variance stabilising transformations will be applied as appropriate to the row data before meta-analysis. This systematic review will be reported according to the MOOSE Guidelines for Meta-Analyses and Systematic Reviews of Observational Studies. ETHICS AND DISSEMINATION: The current study is based on published data and as such ethics consideration is not a requirement. This review is expected to provide relevant data to help in quantifying the magnitude of dyslipidaemia in African populations, to emphasise the need for appropriate prevention and control strategies, and to identify research gaps and remaining challenges. The final report of the systematic review in the form of a scientific paper will be published in peer-reviewed journals. Findings will further be presented at conferences and submitted to relevant health authorities. TRIAL REGISTRATION NUMBER: PROSPERO CRD42014015376.
