Abstract
INTRODUCTION
The increasing highly active antiretroviral therapy (HAART) coverage in sub-Saharan Africa (SSA) has been associated with increasing cardiovascular disease (CVD) incidence. However, the epidemiology of the association between HAART and CVD risk factors in SSA is sparse. We aim to assess the extent to which HAART is associated with selected cardiovascular risk factors (hypertension, diabetes, dyslipidaemia and metabolic syndrome) in SSA.

METHODS AND ANALYSIS
This will be a systematic review and meta-analysis of published studies on the association between HAART and CVD risk factors retrieved from Medline, Embase, Popline, Africa-Wide Information, African Index Medicus and the Cochrane library databases. Studies will be screened for eligibility according to the selection criteria by two independent reviewers. Eligible studies will be assessed for the quality of their evidence and risk of bias using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies of the National Health Institute and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach, with respect to the measured outcomes (hypertension, diabetes, dyslipidaemia and metabolic syndrome). A data abstraction form will be produced on Epi info V.7 and data analysis done on STATA V.14 statistical software. Summary estimates of measures of effects for the association between HAART use and the outcomes will be derived. Random effects meta-analyses will be performed and I(2) statistic used to assess for heterogeneity between studies with respect to measured parameters. Qualitative synthesis will be used where data is insufficient to produce quantitative synthesis.

ETHICS AND DISSEMINATION
The protocol has been reviewed by the Research Governance & Integrity Office of the Research Ethics Committee of the London School of Hygiene and Tropical Medicine and confirmed as not requiring ethical approval. The findings of this study will be made widely available especially to national HIV/AIDS committees formulating HIV/AIDS guidelines for their respective settings.
