The age-related risk of occupational accidents: the case of Swedish iron-ore miners.

The paper examines age-related accident risks faced by Swedish male iron-ore miners. A retrospective longitudinal analysis of national registers was conducted over a ten-year period using three times periods of five years and five age categories. Age-related accident frequency, characteristics and severity were examined. High accident ratios were rare among older miners whatever the time period, but some accident patterns became substantially more frequent in some older age cohorts over the years. Injuries tended to be more severe in older age groups, all accidents aggregated as well as by accident pattern. It is concluded that inequality in risk exposure between age groups may explain the lower accident ratios found among older workers, but also that the aging of a working population may lead to the application of task-assignment principles that penalize older workers, at least with regard to certain specific accident risks.
