RESEARCH DESIGN AND METHODS: Cohort study including 137 pregnant women with type 1 diabetes using aHCL from 27 hospitals in Spain. Participants were grouped according to the aHCL system used: 85 MiniMed 780G (62%), 38 CamAPS FX (27.7%), and 14 Control-IQ (10.2%). Maternal glucose metrics (HbA1c and time spent within [TIRp], below [TBRp], and above [TARp] the pregnancy-specific glucose range 3.5-7.8 mmol/L), as well as pregnancy outcomes, were analyzed. Adjusted models were applied to account for potential confounding factors.
RESULTS: No between-group differences in HbA1c levels were observed at baseline. By the third trimester, CamAPS FX and Control-IQ users had significantly lower HbA1c levels compared with the MiniMed 780G group (βadjusted -4.77 mmol/mol, 95% confidence interval [CI] -7.40 to -2.13; and βadjusted -4.79, 95% CI -8.53 to -1.06; respectively). In the second trimester, CamAPS FX was associated with a higher percentage of time in range (βadjusted +5.88%, 95% CI 1.09 to 10.67) and a lower percentage of time above range (βadjusted -6.36%, 95% CI -11.46 to -1.26) compared with MiniMed 780G, with no other significant differences observed in other trimesters. Both CamAPS FX and Control-IQ were associated with lower odds of large-for-gestational-age (LGA) infants (CamAPS FX: ORadjusted 0.25, 95% CI 0.08 to 0.77; Control-IQ: ORadjusted 0.10, 95% CI 0.01 to 0.99) compared with MiniMed 780G.
CONCLUSIONS: In this multicenter observational study, CamAPS FX and Control-IQ users achieved better glycemic metrics and lower odds of delivering LGA infants compared with those using MiniMed 780G. These findings warrant investigation to confirm associations and inform individualized clinical decision-making in pregnant women with type 1 diabetes.
