Evidence for increasing prevalence of diabetes mellitus in childhood.

The prevalence of diabetes mellitus among the cohort of children in the Child Health and Education Study studied at age 10 was 1.3/1000. Comparison with prevalences found in the two previous British birth cohort studies suggested that the prevalence of diabetes is doubling roughly every decade. The data suggested that childhood diabetics are a socially advantaged group. These findings have important implications and should be taken into account by health service planners if the needs of these children are to be met in the future.
