At a time when new, noninvasive prenatal tests are being trialled and prepared for commercial release in the UK and in North America, the European Journal of Human Genetics (advance online publication 2 July 2008) has published a UK study tracking the evolution of birth rate trends for babies with Down syndrome over 20 years (1985 - 2004).
The trend is complicated by the introduction of widespread pre-natal testing and increasing numbers of all babies born to women over 35 years of age.
The abstract concludes: Increasing maternal age and improved survival of children with Down syndrome have offset the effects of prenatal diagnosis followed by the termination of pregnancy and declining general birth rate.
