Background
Community knowledge is a critical input for relevant health programmes and strategies. How community perceptions of risk reflect the burden of mortality is poorly understood.
Objective
To determine the burden of mortality reflecting community-nominated health risk factors in rural South Africa, where a complex health transition is underway.
Methods
Three discussion groups (total 48 participants) representing a cross-section of the community nominated health priorities through a Participatory Action Research process.
A secondary analysis of Verbal Autopsy (VA) data was performed for deaths in the
same community from 1993 to 2015 (n = 14,430). Using population attributable fractions
(PAFs) extracted from Global Burden of Disease data for South Africa, deaths were categorised
as ‘attributable at least in part’ to community-nominated risk factors if the PAF of the risk
factor to the cause of death was >0. We also calculated ‘reducible mortality fractions’ (RMFs),
defined as the proportions of each and all community-nominated risk factor(s) relative to all
possible risk factors for deaths in the population .
Results
Three risk factors were nominated as the most important health concerns locally:
alcohol abuse
,
drug abuse
, and
lack of safe water
. Of all causes of deaths 1993–2015, over 77% (n = 11,143) were attributable at least in part to at least one community-nominated risk factor.
Causes of attributable deaths, at least in part, to
alcohol abuse
were most common (52.6%, n = 7,591), followed by
drug abuse
(29.3%, n = 4,223), and
lack of safe water
(11.4%, n = 1,652). In terms of the RMF, alcohol use contributed the largest percentage of all possible risk factors
leading to death (13.6%), then
lack of safe water
(7.0%), and
drug abuse
(1.3%) .
Conclusion
A substantial proportion of deaths are linked to community-nominated risk factors. Community knowledge is a critical input to understand local health risks.
