title: [Incidence of IDDM between the ages 0-17 years in Israel in 1998--the Israel IDDM Registry Study Group--IIRSG].
abstract: BACKGROUND
  Based on previous survey data, an increased incidence of IDDM (type 1 diabetes) among children and adolescents was reported by the Israel IDDM Registry Group in 1997. Similar increases have been reported from various countries in past years. This paper presents incidence rates of IDDM among 0-17 years old population for 1998.
  
  
  METHODS
  Methods of data collection were reported in a previous paper. Briefly, this is a population based anonymous registry. New cases are reported to the ICDC by all the centers for type I IDDM diabetes in Israel. Crude incidence rates and specific sex, age and population group rates are presented.
  
  
  RESULTS
  During 1998, 186 new cases of IDDM were reported in the age group 0-17 years. The annual incidence rate in the total population of Israel in 1998 was 9.1 cases per 100,000. Incidence rates for 1998, were higher for Jews (9.5 per 100,000) than for Arabs (8.0 per 100,000). Among Jews, children of Ethiopian origin had the highest incidence rate (18.2 per 100,000), but this finding is based on six new cases. Children of Asian and North African origin had the lowest incidence rate (5.7 per 100,000). Age-specific incidence rates are different in boys and girls. A close family history of IDDM was found in 8.1% of the cases.
  
  
  CONCLUSIONS
  IDDM incidence rates for 1998 are 15% higher than those reported for 1997. The increase in rates was steeper for Arabs (74%) than for Jews (4.4%), leading to a smaller difference between Jews and Arabs than reported in 1997. Verification of the apparent increase in incidence will be possible by the examination of data from the registry in the next few years.
