Abstract

Background and Aims: Disordered eating behaviors (DEB) are more common among individuals with type 1 diabetes (T1D) compared to those without, and for insulin pump users may be associated with higher hemoglobin A1c (HbA1c). We investigated DEB risk factors among insulin pump-treated individuals with T1D and clinical characteristics of hybrid closed-loop (HCL) systems’ users by DEB level. Methods: An observational, cross-sectional study of 167 insulin pump-treated individuals with T1D, 13–21 years of age. Data were obtained from patients’ medical charts with additional self-reported questionnaires, including assessment of DEB. Results: DEB were found in 71 (42.5%) individuals, and positively associated with female sex (b = 2.98 [standard error (SE) = 1.31], P = 0.025), body mass index (BMI)-Z-score (b = 2.12 [SE = 0.64], P = 0.001), HbA1c (b = 1.40 [SE = 0.45], P = 0.02), and higher rate of pump discontinuation (b = 4.48 [SE = 1.99], P = 0.026). The use of HCL systems compared to insulin pumps was associated with higher BMI-Z-score (odds ratio [OR]: 3.46 [95% confidence interval, CI: 1.52–7.87], P = 0.003) and tendency to lower HbA1c level (OR: 0.44 [95% CI: 0.18–1.09], P = 0.078) among individuals without DEB, and with lower HbA1c level (OR: 0.29 [95% CI: 0.10–0.83], P = 0.022) and higher socioeconomic status (OR: 1.73 [95% CI: 1.09–2.74], P = 0.020) among individuals with DEB. Conclusions: DEB are common among individuals with T1D treated with insulin pumps and are associated with higher HbA1c levels. Among T1D individuals with DEB, HCL system use is associated with lower HbA1c compared to insulin pump treatment. Our findings highlight the importance of regular screening for DEB and its risk factors to improve pump treatment and diabetes management. Moreover, individuals with DEB using HCL systems may benefit from reduced HbA1c levels.
