Objective
To study worldwide differences in childhood diabetes, comparing relevant indicators among five regions within the SWEET initiative.
Subjects
We investigated 26 726 individuals with type 1 diabetes (T1D) from 54 centers in the European region; 7768 individuals from 30 centers in the Asia/Middle East/Africa region; 2642 people from five centers in Australia/New Zealand; 10 839 individuals from seven centers in North America, and 1114 patients from five centers in South America.
Methods
The SWEET database was analyzed based on the following inclusion criteria: T1D, time period 2015‐2019, and age < 21 years, with analysis of the most recent documented year of therapy. For the statistical analysis, we used multivariable linear and logistic regression models to adjust for age (<6 years, 6‐ < 12 years, 12‐ < 18 years, 18‐ < 21 years), gender, and duration of diabetes (<2 years, 2‐ < 5 years, 5‐ < 10 years, ≥10 years).
Results
Adjusted HbA1c means ranged from 7.8% (95%‐confidence interval: 7.6‐8.1) in Europe to 9.5% (9.2‐9.8) in Asia/Middle East/Africa. Mean daily insulin dose ranged from 0.8 units/kg in Europe (0.7‐0.8) and Australia/New Zealand (0.6‐0.9) to 1.0 unit/kg 0.9‐1.1) in Asia/Middle East/Africa. Percentage of pump use was highest in North America (80.7% [79.8‐81.6]) and lowest in South America (4.2% [3.2‐5.6]). Significant differences between the five regions were also observed with regards to body mass index SD scores, frequency of blood glucose monitoring and presence of severe hypoglycaemia.
Conclusions
We found significant heterogeneity in diabetes care and outcomes across the five regions. The aim of optimal care for each child remains a challenge.
