Growth of children before onset of diabetes
1Leicester General Hospital, United Kingdom.
Insights
Children who develop diabetes are taller than their peers before diagnosis. This increased height, observed up to three years prior to diagnosis, suggests metabolic changes may precede clinical onset.
Area of Science:
- Pediatric endocrinology
- Growth and development
- Diabetes mellitus
Background:
- Childhood diabetes onset is a significant health concern.
- Understanding pre-diagnostic growth patterns can offer insights into disease etiology.
- Early identification of risk factors is crucial for intervention.
Purpose of the Study:
- To investigate height differences in children prior to diabetes diagnosis.
- To compare the growth trajectories of diabetic children, their siblings, and control subjects.
Main Methods:
- Retrospective analysis of height data (Standard Deviation Scores - SDS) from routine examinations.
- Inclusion of diabetic children identified from a diabetes register.
- Age- and sex-matched control subjects and siblings were included for comparison.
Main Results:
- Diabetic children exhibited significantly greater height (SDS) compared to controls 0-3 years before diagnosis (p<0.05 to p<0.001).
- Height differences were not significant beyond 3 years pre-diagnosis.
- Siblings of diabetic children did not show increased height compared to controls.
Conclusions:
- Elevated height in children precedes clinical diagnosis of diabetes, suggesting metabolic alterations.
- Growth-inducing metabolic changes may occur at least three years before diabetes onset.
- This finding may aid in understanding the pathophysiology of childhood diabetes.
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.

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
