Abstract
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: (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.
