Type 1 diabetes mellitus in children in Papua New Guinea.

: Anecdotal and published information suggest a low incidence and prevalence of type 1 diabetes in Papua New Guinea (PNG). Incidence and prevalence were followed prospectively from July 1996, using the PNG Paediatric Surveillance Unit (PSU). No children were receiving insulin in Papua New Guinea at the start of the period. Over the next 4.5 years, 8 cases were reported--an annual incidence of 0.08/100,000 children aged < 15 years and a prevalence of 0.28/100,000 aged < 15 years. These figures are as low as any reported elsewhere. Three cases were from the small expatriate population. All cases in Melanesian children posed significant management problems, with two children dying during the study period.
