Insights
Children with type 1 diabetes mellitus (T1DM) in The Netherlands face a significantly higher risk of thyroid disease. This study found T1DM increases thyroid disease likelihood by 24 times, with girls being more susceptible.
Area of Science:
- Endocrinology
- Pediatrics
- Public Health
Background:
- Type 1 diabetes mellitus (T1DM) is an autoimmune condition.
- Thyroid dysfunction is a common comorbidity in autoimmune diseases.
- Understanding the prevalence of thyroid disease in children with T1DM is crucial for early detection and management.
Purpose of the Study:
- To determine the prevalence of overt thyroid disease in Dutch children with and without T1DM.
- To compare the risk of thyroid disease in children with T1DM versus those without.
- To investigate potential sex differences in thyroid disease prevalence among children with T1DM.
Main Methods:
- A nationwide, retrospective cohort study was conducted in The Netherlands.
- Data were collected from national healthcare reimbursement and pharmaceutical care registries.
- The study included Dutch children aged 0-14 years diagnosed with T1DM, hypothyroidism, or hyperthyroidism between 2009-2011.
Main Results:
- The prevalence of thyroid disease was 3.43% in children with T1DM, compared to 0.15% in children without T1DM (rate ratio 23.59).
- Both hyperthyroidism and hypothyroidism were 24 times more likely in children with T1DM.
- Thyroid disease was more prevalent in girls than boys, particularly hypothyroidism, with a more pronounced sex difference in the T1DM group.
Conclusions:
- Children with T1DM in The Netherlands exhibit a substantially higher risk of developing thyroid disease.
- The findings highlight the importance of screening for thyroid dysfunction in pediatric T1DM patients.
- Girls with T1DM, especially those with hypothyroidism, represent a particularly vulnerable subgroup.
Objective:
To investigate the prevalence of overt thyroid disease in children in The Netherlands with and without type 1 diabetes mellitus (T1DM).
Study Design:
Nationwide, retrospective cohort study in The Netherlands. Using the national registry of both healthcare reimbursement and pharmaceutical care, data of all Dutch children (aged 0-14 years) with a diagnosis of T1DM, or a diagnosis of hypothyroidism or hyperthyroidism in the period 2009-2011.
Results:
The prevalence of thyroid disease was 0.15% in children without T1DM, and 3.43% in children with T1DM (rate ratio 23.59; 95% CI 19.92-27.93; P < .001). Both hyperthyroidism and hypothyroidism were 24 times more likely in children with T1DM than in those without. Thyroid disease was more common in girls than in boys, both in children with T1DM (rate ratio of girls vs boys 3.07; 95% CI 2.10-4.49) and in children without T1DM (rate ratio 1.59; 95% CI 1.49-1.69). This sex difference was more pronounced for hypothyroidism than for hyperthyroidism.
Conclusions:
Children with T1DM in The Netherlands are 24 times more likely to develop thyroid disease than their peers without diabetes. Girls with T1DM were more prone to thyroid disease, particularly hypothyroidism.

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...
