Increasing Incidence Of Type 1 Diabetes Among Children In Finland Appears To Have Leveled Off
"The incidence of type l diabetes (T1D), one of the most prevalent chronic diseases in children, has increased worldwide," write Valma Harjutsalo, Ph.D., of the Diabetes Prevention Unit, Helsinki, Finland, and colleagues, who conducted a study to examine the incidence rates of T1D between 2006 and 2011 in Finnish children younger than 15 years as well as the 32-year trend (1980-2011).
As reported in a Research Letter, all children with newly diagnosed T1D were ascertained using several nationwide registers. Age-standardized and age-specific annual incidence rates for age groups 0-4, 5-9, and 10-14 years were calculated. A total of 14,069 children (7,695 boys and 6,374 girls) were diagnosed with T1D between 1980 and 2011, of whom 3,332 were new cases between 2006 and 2011. The peak incidence was observed in 2006. Analysis indicated 2 significant changes in the longer-term trend. After a modest increase until 1988, the incidence increased annually by 3.6 percent until 2005, followed by a plateau until the end of 2011.
