Prevalence of underweight, overweight, and obesity in children and adolescents with type 1 diabetes: Data from the international SWEET registry.

• To assess the prevalence of underweight (UW), overweight (OW), and obesity in children and adolescents with type 1 diabetes (T1D).An international cross-sectional study including 23026 T1D children (2-18 years, duration of diabetes ≥1year) participating in the SWEET prospective, multicenter diabetes registry. Body mass index SD score (BMI-SDS) was calculated using the World Health Organization BMI charts. Children were categorized as UW (BMI-SDS<-2SD), OW (+1SD+2SD). Hierarchic regression models were applied with adjustment for sex, age, and duration of diabetes.The prevalence of UW, OW, and obesity was: 1.4%, 22.3%, and 7.3% in males and 0.6%, 27.2%, and 6.8% in females. Adjusted BMI-SDS was significantly higher in females than in males (mean±SEM: 0.54±0.05 vs 0.40±0.05, P<0.0001). In males, BMI-SDS significantly decreased by age (P<0.0001) in the first three age categories 0.61±0.06 (2 to <10years), 0.47±0.06 (10 to <13 years), 0.34±0.05 (13 to <16 years). In females, BMI-SDS showed a U-shaped distribution by age (P<0.0001): 0.54±0.04 (2 to <10years), 0.39±0.04 (10 to <13 years), 0.55±0.04 (13 to <16 years). BMI-SDS increased by diabetes duration (<2years: 0.38±0.05, 2 to <5years: 0.44±0.05, and ≥5years: 0.50±0.05, P<0.0001). Treatment modality did not affect BMI-SDS. Adjusted HbA1c was significantly higher in females than in males (8.20%±0.10% vs 8.06%±0.10%, P<0.0001). In both genders, the association between HbA1c and BMI-SDS was U-shaped with the highest HbA1c in the UW and obesity groups.The high rate of OW and obesity (31.8%) emphasize the need for developing further strategies to prevent and treat excess fat accumulation in T1D.
