OBJECTIVE- To determine the incidence of insulin-dependent diabetes me
llitus in 0- to 14-year-old children in Shanghai, China, from 1980 to
1991. RESEARCH DESIGN AND METHODS- Data were collected from hospitals
with pediatric departments. The secondary source of validation was pri
mary and middle schools. RESULTS- The average crude annual incidence r
ate was 0.61/100,000 (95% confidence interval, 0.48-0.77). The ascerta
inment-corrected incidence rates were 0.72/100,000 (0.57-0.91). CONCLU
SIONS- The incidence of childhood diabetes in Shanghai, China, was one
of the lowest, if not the lowest, in the world.
