[Epidemiologic analysis of occupational accidents using data of the Swiss National Accident Insurance].

The present study is aimed to relate occupational accidents, as recorded by SAIF for 1974, to several risk factors among which the size of industrial enterprises. The results seem to demonstrate that very small enterprises (of less than ten employees) produce the highest rate of occupational accidents and accumulate risk factors. Nevertheless, before going very much further in the comment of results, the authors emphasize the limitations of the available statistical material. Further limitation in planning an ergonomical prevention programme on the basis of those records is to be related to the parameters chosen to explain the genesis of occupational accidents.
