. Hagberg, B., Hagberg, G., Lewerth, A. and Lindberg. U. (Department of Paediatrics II, Östra sjukhuset, Gothenburg, Sweden). Mild mental retardation in Swedish School children. I. Prevalence. Acta Paediatr Scand, 70:441, 1981.In an unselected series of Swedish school children born 1966‐70, the prevalence of mild mental retardation, defined as an IQ of 50–70, was determined. A prevalence of 0.4 % was revealed. The findings in this study, supported by recent IQ analyses in other Scandinavian countries, indicate that a true prevalence for the IQ range 50–70 was ascertained. The high average social standard and early social stimulation are put forth as a likely explanation for the low prevalence of mild mental retardation in Swedish preschool and school children.
