A comparative risk assessment for South Africa in 2000: Towards promoting health and preventing disease

Abstract

A landmark project of the Medical Research Council, the first South African National Burden of Disease (SA NBD) study, identified the underlying causes of premature mortality and morbidity experienced in South Africa in the year 2000. (1) These estimates were recently revised (2) on the basis of additional data to estimate the disability-adjusted life years (DALYs) for single causes for the first time in South Africa. DALYs are a comprehensive measure of the disease burden combining the years of life lost (YLLs) as a result of premature mortality and years lived with disability (YLDs) related to illness or injury. (3) Compared with the use of mortality as a measure of disease burden, DALYs also capture the contributions of conditions that do not result in large numbers of deaths. For example, mental health disorders have a large disability component relative to the number of deaths. The SA NBD study highlighted the fact that despite levels of uncertainty there is important information to guide public health responses to improve the health of the nation
