Abstract

BACKGROUND: Intensive treatment of patients with type 1 diabetes delays the onset of long-term complications. OBJECTIVES: On the basis of the information from two nation-wide quality registers, we investigated to which extent HbA1c values 3-15 months after diagnosis in childhood are related to metabolic control, albuminuria, and retinopathy in early adulthood. METHODS: In Sweden, physicians register all children and adolescents with type 1 diabetes mellitus in the Swedish Pediatric Quality Registry. After 18 yr of age, people with diabetes are followed by the Swedish National Diabetes Register. We identified 1543 children and adolescents with a mean age of 13.9 yr at diagnosis and a mean duration of type 1 diabetes mellitus of 7.1 yr. RESULTS: Children and adolescents with poor metabolic control (mean HbA1c ≥ 70 mmol/mol (8.6 %)) adjacent to diagnosis had a significantly higher mean HbA1c value years later as adults than did patients with a good metabolic control [<50 mmol/mol (6.7%) (p < 0.001)]. The patients in the high group were also less physically active and smoked more as adults. The proportion of females was higher in the poor metabolic group. Patients with a high mean HbA1c 3-15 months after diagnosis had significantly more often macroalbuminuria and retinopathy in early adulthood. CONCLUSIONS: Metabolic control adjacent to the diagnosis of type 1 diabetes in childhood or adolescence can predict metabolic control in early adulthood. It is therefore very important that pediatric diabetes teams identify key factors for successful early metabolic control. Actively using quality registries may be one such factor.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
