Doctoral Thesis

In this thesis, four studies on children and adolescents with Down syndrome are described. The first study showed that the number of live births of children with Down syndrome in the Netherlands remained stable over the period 1997-2007 on 14.6 per 10,000 births. Of these, 85% were live born. In the second study is observed that growth retardation in children with Down syndrome meanly occurs in three critical periods of growth, resulting in shorter final stature and smaller head circumference than the general Dutch population shows. Furthermore, Dutch children with Down syndrome have alarmingly high prevalence rates of overweight and obesity during childhood and adolescence. The third study showed that eight-year-old children with Down syndrome have an average developmental delay of four years, more often have emotional and behavioral problems, and have a less favorable health-related quality of life (HRQoL) compared with children from the general population. Children with Down syndrome and recurrent respiratory tract infections showed relatively more delayed development. In the fourth study, results showed that adolescents with Down syndrome remain dependent to a large degree and have serious difficulties in functioning socially. Additionally, results showed that serious problem behavior is highly prevalent in adolescents with Down syndrome.
