Improvements in Parental Sleep, Fear of Hypoglycemia, and Diabetes Distress With Use of an Advanced Hybrid Closed-Loop System

OBJECTIVE Parental sleep quality may contribute to glycemic control in youth with type 1 diabetes. In this article we present sleep analysis from a multicenter, randomized trial of children ages 6-13 years with type 1 diabetes evaluating the Tandem Control-IQ (CIQ) hybrid closed-loop (HCL) system. RESEARCH DESIGN AND METHODS Pittsburgh Sleep Quality Index (PSQI) scores were assessed at baseline to identify parents as "poor" sleepers (PSQI >5). Glycemic and psycho-behavioral outcomes before and after CIQ use were analyzed in poor sleepers (n = 49) and their children. RESULTS Nocturnal time in range (P < 0.001) and time hyperglycemic (P < 0.001), Hypoglycemia Fear Survey for Parents score (P < 0.001), Problem Areas in Diabetes scale score (P < 0.001), PSQI score (P < 0.001), and Hypoglycemia Fear Survey for Children score (P = 0.025) significantly improved. Of poor sleepers, 27 became good sleepers (PSQI score <5). CONCLUSIONS Use of CIQ in youth with type 1 diabetes ages 6-13 years significantly improved sleep and psychosocial measures in parent poor sleepers, coinciding with improvements in child nocturnal glycemia, highlighting the relationship between HCL systems and parent sleep quality.
