Aims: To investigate the impact of time in range (TIR) on mood in adults with type 1 diabetes (T1D). Methods: We followed a cohort of 219 T1D adults, all currently employing a real-time continuous glucose monitoring system (RT-CGM), to investigate how daily changes in CGM metrics were associated with nightly reports of positive and negative mood over a two-week period. Results: Greater daily %TIR (70-180 mg/dL) and less time in severe hyperglycemia (% time above range (TAR) 0.05). When entered together as predictors, %TIR but not %TAR 300 emerged as an independent predictor of many of the positive and negative mood variables. Neither daily changes in time spent in hypoglycemia (< 70 mg/dL) nor glycemic variability (represented by the coefficient of variation) were significantly related to reported mood. Conclusions: This study provides the first evidence that time in range (%TIR) is associated with, and likely enhances, daily mood. Consistent with previous studies, we also found that more time spent in severe hyperglycemia is linked to more negative mood. (c) 2020 Elsevier Inc. All rights reserved.
