[Development conditions and development status of 10-year-old children in Basle].

Children from the "Basle Kindergarten Study" (born 1971-73) were re-examined during their 4th year of primary school, i.e. at the age of ten (1981-84) (Follow-up of a representative sample of 10% of all children in the first year of kindergarten). The aim of this study is to analyse differences in physical and psycho-social development of children living in different conditions, particularly between immigrant and Swiss children. First results are discussed.
