title: Diabetes in Western Australian children: descriptive epidemiology.
abstract: The prevalence and incidence of diabetes mellitus in the age group zero to 14 years in Western Australia were determined from a survey by means of Schools Health Services. Additional information from the State's computer-linked hospital records system, the State's only children's hospital, diabetic clinics and physicians enabled virtually complete ascertainment of cases of childhood diabetes. Only 60% of school-age diabetic children were known to school nurses before the survey, but the nurses were able to identify two-thirds of the remainder during the survey. Among non-Aboriginal children, the prevalence of diabetes in the age group zero to 14 years was 0.59 per 1000 children and the incidence was 12.3 per 100,000 children per year. These rates are somewhat lower than those that have been reported from the United Kingdom and North America, and substantially lower than the rates that were reported from Scandinavia. All but one of the diabetic children who were identified required insulin and were assumed to be insulin-dependent. An excess of boys was found. None of 8715 Aboriginal or part-Aboriginal children had insulin-dependent diabetes mellitus, which indicates that this racial group has a low prevalence of this condition. In case--control studies, which used questionnaires for parents, no significant trends were found in relation to the history of immunizations or of specific viral illnesses except for a past history of varicella which was less frequent in diabetic children. A past history of established breast-feeding (of more than one week) was less frequent in diabetic children, as was the ingestion of vitamin C supplements before the onset of diabetes. Some evidence for a seasonality of onset was obtained. The diabetic children were absent from school for more days and had more admissions to hospital than did non-diabetic children. The majority of diabetic children were prescribed insulin twice a day or more often (84%); performed home blood-glucose monitoring (74%); and attended hospital diabetic clinics (91%).
