(!12) Complications of anorexia nervosa accounted for 54 per cent of deaths, suicide for 27 per cent, and other causes for 19 per cent. When the death rate is expressed as a percentage per annum a fair measure of consistency has been found in different parts of the world, especially when allowance is made for selection biases: in Denmark 0.5 per cent per annum (younger patients)/1,,13) in Sweden 0.75 per cent per annum/1,!0) in the United States 0.66 per cent per annum, (H4) and in the United Kingdom 0.75 per cent per annum.(111)
