A theoretical and practical discussion took place some years ago about the selection of high risk groups for the implementation of preventive activities. Particularly important in this discussion was Geoffrey Roses seminal work.1 In this work, Rose set out the main advantages and disadvantages of such a "high risk group" preventive strategy. In Roses words, it is a strategy with some clear and important advantages:

- The "high risk" approach also offers a more cost effective use of limited resources and a more favourable ratio of benefits to risks.
