A statistical analysis of Cambridge University Health Service records, 1948–50.

The Cambridge University Health Service started work in October 1948. So far it has been restricted to preventive measures and has been confined to new entrants to the University on an entirely voluntary basis. The Service provides a clinical examination and a chest X-ray. A general survey of the scope of the Service and the results obtained have been given in the annual reports of the Senior Health Service Officer, Sir Alan Rook (1950, 1951). In addition to the original clinical records a Hollerith punched-card record system has been used since the inception of the Service to facilitate detailed investigations. In Appendix I to the first annual report mentioned above (Rook, 1950) I gave a few preliminary results on various physical measurements for the first 900 men examined. It has now been possible to complete a much more extensive investigation, the results of which are given in the present paper. In some cases this has been based on the completed records for the year 1948–9, while in others the records for the two years 1948–50 have been utilized. I have already given a brief summary of the contents of this paper in Appendix I to the second annual report (Rook, 1951). [ABSTRACT FROM PUBLISHER]
