Variations in mortality of the coloured, white and Asian population groups in the RSA, 1978-1982. Part I. All causes.

Previous reports, based largely on the 1970 census and the 8th revision of the International Classification of Diseases, (ICD-8) have suggested that marked differences in mortality exist between population groups in the RSA. In this article the ICD-9 classification of causes of death and 1980 census are used to assess whether the trends have continued through to the present time. Total mortality data in the RSA for whites, coloureds and Asians for the 5-year period 1978-1982 are presented. The 1980 national census provided the denominator population data. Annual age- and sex-specific mortality rates were higher for coloureds than for whites or Asians, the differences being most marked in childhood. There appears to have been little change in total standardised mortality rates among whites over the 5-year period, while increases have occurred among coloureds of both sexes and among Asian males. Analysis of proportional mortality stresses the relatively large proportion of deaths accounted for by external causes and infections among coloureds and by cardiovascular diseases among whites and Asians. There is an urgent need for the health services to take note of these data in order to provide for the varied needs of the population.
