摘要

The figure compares total numbers of Down's syndrome diagnoses (top line, rising from 1075 in 1989/90 to 1843 in 2007/8) with estimated numbers of Down's syndrome live births that would have occurred in the absence of antenatal diagnoses and selective termination (middle line, rising from 959 in 1989/90 to 1422 in 2007/8). The two lines differ because the top line includes pregnancies detected antenatally and terminated that, had the pregnancy continued, would have miscarried naturally and not resulted in a live birth. The bottom line shows estimated numbers of live born babies with Down's syndrome in the presence of antenatal diagnoses and selective termination (falling from 752 to 743, 1.10 to 1.08 per 1000 births). The difference between the bottom two lines is attributable to antenatal screening and subsequent terminations, the effects of which have clearly increased over time. The rise in the number of live births expected in the absence of screening and subsequent terminations is due to a true increase in the incidence of Down's syndrome, which can be attributed to the increase in maternal age.
