title: Increasing incidence of type I diabetes in The Netherlands. The second nationwide study among children under 20 years of age.
abstract: OBJECTIVE
  A nationwide retrospective study was conducted to assess the incidence of type I diabetes in The Netherlands among children < 20 years of age in 1988-1990. The first study with a similar design covered 1978-1980.
  
  
  METHODS
  The capture-recapture census method was chosen for analysis of the data. A questionnaire was sent to all Dutch pediatricians and internists, and for the ascertainment, a similar questionnaire was sent out separately to members of the Dutch Diabetes Association, which is the national patient association.
  
  
  RESULTS
  The average achieved ascertainment rate was 81%. The ascertainment-adjusted annual incidence was 13.2/100,000 for 0- to 19-year-old children, indicating an increase of 23% compared with the 1978-1980 survey; for 0- to 14-year-olds, the increase amounted to 17%.
  
  
  CONCLUSIONS
  This study suggests a sustained increase of type I diabetes in The Netherlands because the cumulative incidence studied previously in the 1960-1970 birth cohorts of male army conscripts 18 years of age was also found to rise. In contrast to Northern European countries, an increase in incidence for the age category 0-4 years could not be found.
