Incidence of gastric and duodenal ulcer in the Royal Air Force in 1955.

In a previous paper (Baron and Vaughan Jones, 1958) we discussed the difficulties of estimating the prevalence of gastric and duodenal ulcer. We concluded, as had Doll (1952), that a population survey was the method of choice, and we studied the whole British Army of 1955. Some of our findings were sufficiently different from those of British and other civilians for us to seek anotherlarge population. In 1955 there were 245,320 men (officers and other ranks) in the Royal Air Force (R.A.F.). We have analysed the morbidity from peptic ulcer diagnosed that year for the first time.
