Abstract
Introduction 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.
