“…For total Caucasians our figures were, males 15-1l%, females 18.0%. Prevalence increased with age, in the groups studied, as found by others (Reid et al, 1936;Young & Russell, 1939;Erasmus, 1939;Lee, 1962;Wright, 1963;Ludbrook & Spears, 1965;Ashley, 1967;Howorth, 1969). Evidence suggests that in urban Negroes, prevalence of appendicectomy has doubled since 1939 (Erasmus, 1939).…”

“…They are especially apposite for study since peak prevalence of appendicectomy occurs at late adolescence, 15-19 years (Reid, Poer & Merrel, 1936;Young & Russell, 1939;Lee, 1962;Wright, 1963;Ashley, 1967;Howorth, 1969). Subjects, males and females, .in the four ethnic groups included (i) 10,101 senior pupils at schools in Johannesburg, Durban, and a number of country districts; and (ii) 5216 students attending Universities or Colleges in Johannesburg, Pretoria, Potchefstroom, Grahamstown and Durban.…”

“…In one mining group the labour force is about 100,000. Firstly, taking into account the war-time appendicectomy incidence in the U.S.A. Navy (Editorial, Wright (1963) and Ashley (1967), calculations indicate that prevalence of the operation per total population of South African Caucasians is about 17%, a proportion which closely resembles that for England (Ashley, 1967), about 14%, and for New Zealand (Ludbrook & Spears, 1965), about 16%. These two items of information suggest that the standard of judgment as to whether or not to perform appendicectomy is roughly the same in different parts.…”

“…In primitive and under-privileged populations in developing countries, appendicitis is rare, yet it rises in prevalence with improvement in socio-economic circumstances (Gelfand, 1956;Trowell, 1960;Boroda, 1961;Bremner, 1964;Janssens & de Muynck, 1966;Burkitt, 1969Burkitt, , 1971 less ago, the disease in western populations was infrequent (Mackenzie, 1878;Brunton, 1896;MacEwen, 1904;Murray, 1914;Mayo, 1924); at present it is the foremost cause of abdominal emergencies (Wright, 1963;Janssens & de Muynck, 1966;Ashley, 1967). Rendle Short (1920Short ( ,1946 maintained that the increase correlated with changes in diet, principally the progressive decrease in the consumption of crude fibre; the level of intake of this component regulates bowel motility and the amount of faeces voidedper diem (Rendle Short, 1920, 1946Hoppert & Clark, 1945;McCance & Widdowson, 1946;Walker, 1947Walker, , 1961Walker, , 1970Janssens & de Muynck, 1966;Burkitt, 1971).…”

SummaryInformation on appendicectomy-prevalence was secured on 15,317 16-20-year-old South African pupils and students-Negroes, Coloureds (Eurafricans), Indians and Caucasians. Data were also obtained on crude fibre-intake, frequency of defaecation, and transit-time of digesta.Among students, 18-20 years, appendicectomy was very uncommon in rural Negroes (0-5%.) and periurban Negroes (0-9y/), slightly more common in urban Negroes (1F4y.), but very common in Caucasians (16-5%); prevalences in Coloured and Indian groups were low (1F7 and 29%y). Rural Negroes had a far larger fibre-intake, greater frequency of defaecation, and much shorter transit-time; yet, in the four ethnic groups in urban areas, despite wide differences in appendicectomy-prevalence, data on these variables were similar. Differences in other aspects of the bowel milieu int6rieur must therefore be sought. Corresponding studies were made on 1325 Caucasian pupils in Homes; their diet is less sophisticated (in respect of fibre, sugar and fat-intakes) than that of the general population. Pupils had slightly greater defaecation-frequency, lesser transit-time, and an appendicectomy-incidence only 23%/ of that of an appropriate control-group. The conclusion is reached that the causes of appendicitis are wholly environmental.
