title: Contribution of developmental disabilities to childhood mortality in the United States: a multiple-cause-of-death analysis.
abstract: Although developmental disabilities are among the major chronic health problems affecting children in the United States, the contribution of developmental disabilities to childhood mortality is unknown. To investigate the magnitude of this contribution, multiple cause-of-death data were examined for US children, aged 1-19 years, for 1980 and 1983-1989. The following conditions were included as developmental disabilities: autism, attention deficit disorder, learning disorders, mental retardation, cerebral palsy, epilepsy, muscular dystrophy, blindness and deafness. Based on underlying cause only, it was found that developmental disabilities were the fifth leading cause of nontraumatic death for children between 1 and 14 years of age and the third leading cause of non-traumatic death for children between 15 and 19 years. When a multiple cause approach was used to define developmental disability-related deaths (i.e. when contributing as well as underlying cause was considered), the number of such deaths nearly doubled. On the basis of both underlying- and multiple-cause analyses, cerebral palsy was the developmental disability most frequently cited as a cause of death. Mental retardation ranked second according to the multiple-cause approach but only fourth according to the underlying-cause approach. The least frequent causes of death (autism, attention deficit disorder, learning disorders, blindness, and deafness) were the ones most likely to be coded as contributing rather than underlying causes. Developmental disability-related mortality rates were highest among children aged 1-4 and 15-19 years, highest among blacks and lowest among racial groups other than blacks and whites, and higher among males than females. Although results of multiple-cause-of-death analyses more accurately reflect the proportion of deaths related to developmental disabilities, even this approach may underestimate the degree to which mortality is associated with a developmental disability.
