Abstract
To look at the underlying cause of death (U.C.O.D) data for Down syndrome (DS), we studied 324 DS individuals who died out of a total of 1,337 DS births occurring in 1,066,508 consecutive live births during the years 1952-81 inclusive. U.C.O.D rates, separated into ICD-9 classifications, for the DS population were compared with those of the age-matched general population. In general, an individual with DS is significantly more likely to die than the age-matched general population over all ages studied up to age 30. The greatest absolute likelihood of dying is under 1 year, but the age group with the greatest relative risk of dying (17.2) is very definitely between ages 1-9. In order, the three categories for causes of death in DS with the greatest relative risk are congenital anomalies, circulatory system, and respiratory system.
