For some examples, see Table 4 from Strauss et al. which is reproduced below. It applies to a 25 year-old male. As may be seen, in the most severe case (complete injury at levels C1 � C3), the life expectancy is 50% of normal. For grade D injuries (inimal neurological deficit), the estimate is 88% of normal. For females, or for persons older than 25, the percentage of normal life expectancy is similar, to a rough approximation, though the percentage tends to be somewhat smaller at older ages.
Persons whose Spinal Cord Injury occurred in childhood have lower life expectancies than those injured in adulthood, other factors being equal.

Secular trends in life expectancy after Spinal Cord Injury. It seems to be widely believed that life expectancy after SCI has improved dramatically in recent decades. A careful reading of the research literature5,7,9 shows, however, that the pattern is more complex than this. There has been a major improvement in survival during the critical first few years after the injury, mortality rates having fallen by some 50% in recent decades. For the subsequent period, however, there has been little if any improvements in survival.
Smoking and Spinal Cord Injury. The research literature indicates that smoking is especially deleterious for persons with Spinal Cord Injury.
The same appears to be true of persons with SCI who are morbidly obese.
It has been suggested that economic factors play a major role in life expectancy of persons with Spinal Cord Injury.More recent work,1 however, indicates that this is not the case, except that persons with SCI in the most unfavorable economic category fare significantly worse than the others.
