Insights
Anthropometric indices in children with type 1 diabetes mellitus (T1DM) have changed, with increasing height and BMI. This trend highlights the need for awareness of cardiovascular disease risks in pediatric T1DM patients.
Area of Science:
- Pediatric Endocrinology
- Metabolic Disorders
- Diabetes Mellitus Research
Background:
- Anthropometric indices in children with type 1 diabetes mellitus (T1DM) have shown recent changes.
- Understanding these shifts is crucial for managing long-term health outcomes.
Purpose of the Study:
- To investigate secular trends in anthropometric indices among Japanese children with T1DM.
- To analyze changes in height, BMI, and obesity prevalence over time.
Main Methods:
- Analysis of data from Japanese children with T1DM across multiple cohorts (1995-2013).
- Evaluation of serum HbA1c, severe hypoglycemia incidence, insulin types/doses, height SDS, BMI percentiles, and obesity prevalence.
- Stratification of patients based on glycaemic control levels.
Main Results:
- Decreased incidence of severe hypoglycemia and increased use of insulin analogues.
- Significant increases in height SDS, BMI percentile, and obesity prevalence.
- Height SDS increased across all glycaemic control groups; BMI and obesity increased in suboptimal and high-risk groups.
Conclusions:
- Children with T1DM have shown increased average height and BMI since 1995, correlating with higher insulin doses.
- Clinicians must recognize the rising BMI in T1DM pediatric patients.
- Increased BMI necessitates awareness of future cardiovascular disease risks.
Background:
Recently, anthropometric indices in children with type 1 diabetes mellitus (T1DM) have begun to change.
Objective:
To examine secular trends in patients' anthropometric indices.
Subjects:
Japanese children with T1DM from the 1995, 2000, 2008 and 2013 cohorts of The Japanese Study Group of Insulin Therapy for Childhood and Adolescent Diabetes.
Methods:
We analysed serum haemoglobin A1c (HbA1c) levels, the incidence of severe hypoglycaemic events, the types and doses of insulin, height standard deviation scores (SDS), body mass index (BMI) percentiles compared with healthy Japanese children and obesity prevalence over time. We also stratified the patients according to glycaemic control levels of <58 mmol/mol (optimal), 58-75 mmol/mol (suboptimal) and ≥75 mmol/mol (high-risk).
Results:
Data for 513-978 patients from each of the cohorts were analysed. The incidence of severe hypoglycaemic events decreased over time (from 21 to 4.8/100 patient-years), while the proportion of insulin analogue doses increased (14.6% to 98.6%). In addition, patient height SDS (-0.22 to +0.17), BMI percentile (52.1 to 58.7) and obesity prevalence (2.1% to 5.1%) increased. Height SDS increased in all of the glycaemic control subgroups, while BMI percentile and obesity prevalence increased in the suboptimal and high-risk groups.
Conclusions:
Since 1995, the average height of children with T1DM has increased in parallel with increasing insulin doses. Clinicians should be aware of increased BMI in these patients and the associated risk of developing cardiovascular disease in the future.
