Mortality of Twins

  • Virginia J. Baldwin


It is tough to be a twin! The risks of disorder, disease, and death are greater for all members of a plural set from the moment of conception to the end of their life span, and encompass physical, psychological, and social threats.1, 2 There seems to be universal agreement on this concept although the reported statistical magnitude and details vary widely. It has been suggested that the frequency of twinning at conception may actually be as high as one in eight, and that for every live-born twin pair, there would appear to be at least six singletons who are actually sole survivors of twin conceptions, and in the remainder, the entire conception is lost, in the majority prior to clinical recognition.3 Mortality of twins is thus a numerically important problem, and is the focus of this chapter. Morbidity of twins is discussed in Chapter 6, and Chapter 7 deals with anomalous development of twins.
