OBJECTIVE: To examine the growth of children before the onset of diabetes. RESEARCH DESIGN AND METHODS: Heights before diagnosis, expressed as SDS, of each diabetic child identified from the diabetes register and of two age- and sex-matched control subjects were obtained from records of routine examinations performed at 3.5, 6, 11, and 13 yr. The heights of their siblings, with control subjects, also were obtained. RESULTS: Diabetic children were considerably taller than control subjects before diagnosis (0-1 yr before diagnosis SDS 0.82 +/- 0.26 vs. 0.16 +/- 0.14, P less than 0.05, n = 24; 1-2 yr before diagnosis SDS 1.02 +/- 0.17 vs. 0.16 +/- 0.14, P less than 0.001, n = 30; 2-3 yr before diagnosis SDS 0.97 +/- 0.23 vs. 0.04 +/- 0.20, P less than 0.005, n = 16). At more than 3 yr before diagnosis, the diabetic children were not significantly taller than control subjects (SDS 0.8 +/- 0.2 vs. 0.27 +/- 0.13, respectively; n = 33). The siblings of the diabetic children were no taller than control subjects. CONCLUSIONS: Diabetic children, but not their siblings, were taller than control subjects before diagnosis, suggesting growth-inducing metabolic changes may precede the onset of clinical diabetes by at least 3 yr.
