| Authors: | I D Young E M Williams R G Newcombe |
| Abstract: | Seventy cases of Down syndrome have been ascertained in South Glamorgan during the period 1968 to 1976. This gives an overall incidence of 1 in 658 live births. Analysis of the data on the basis of single years of maternal age gives an incidence of 1 in 200 by 36 years, 1 in 100 by 40 years, and 1 in 50 by 44 years. All incidence figures are for live births at age of delivery. |
