Incidence of Type 1 Diabetes in Sweden Among Individuals Aged 0–34 Years, 1983–2007

Abstract

Twenty-five years of prospective nationwide incidence registration demonstrates a clear shift to younger age at onset rather than a uniform increase in incidence rates across all age-groups. The dominance of cohort effects over period effects suggests that exposures affecting young children may be responsible for the increasing incidence in the younger age-groups.
