This is a retrospective survey of all cases of Down syndrome recorded between 1981 and 2000 to mothers resident in Co. Galway. The study compares the incidence of Down syndrome in both decades and examines the effects of changing demographics on incidence rates. The overall prevalence rate was 26.8/10,000 live births for the full period. Although there were 5119 fewer births in the 1991-2000 period, the prevalence was 29.8/10,000 compared to 24.1/10,000 in the previous decade. Despite the falling birth rates and fertility rates observed in our study between the two decades we found that the higher prevalence of Down syndrome in the second decade was directly related to the significant increase in the proportion of women in the 30 plus age group. Our study also found the place of the child with Down syndrome in the family changed, with 25.3% being the 5th or more child in the first decade compared with 9.5% in the second decade.This is a retrospective survey of all cases of Down syndrome recorded between 1981 and 2000 to mothers resident in Co.
