A follow up study of a cohort of 280 Down's syndrome (DS) fetuses was
initiated in order to estimate the percentage of terminations of pregn
ancy, the prevalence at birth, the survival of DS children, the attitu
de of the parents at birth, and the medical and surgical care provided
. The present study is a preliminary analysis of the data collected up
to the age of 1 year. It shows that 43% of the 280 DS fetuses had die
d by the end of the first year of life, owing to termination of pregna
ncy (27%), late spontaneous abortion or stillbirth (4%), or death duri
ng the first year of life (12%). Among the 33 children who died, 12 ha
d a common atrioventricular canal, six had another major malformation,
three died fi om infection, one from respiratory distress, two were c
ot deaths, and one was an infanticide, but eight deaths were unexplain
ed, occurring in children with no known malformation or disease. Among
the 185 children still alive after 2 days, 23 (12%) were available fo
r adoption, their mothers having elected to remain anonymous. These re
sults show that in some instances parents or professionals feel justif
ied on one hand in not providing DS children with the necessary care a
nd on the other hand to transfer their responsibilities to the public
health system. The influence of prenatal diagnosis of chromosome disor
ders as a determining factor of the social acceptance of DS is still q
uestionable.
