Key result
Calculating nocturnal systolic blood pressure dip using actual sleep time resulted in a mean decline of 11.6% compared to 8.8% using a preset sleep time (P<0.0001).
Why the study?
Does using actual reported sleep time compared to preset sleep time improve the accuracy of diagnosing abnormal nocturnal systolic blood pressure dipping in adolescents with type 1 diabetes?
Observational (n=98)
Does using actual reported sleep time compared to preset sleep time improve the accuracy of diagnosing abnormal nocturnal systolic blood pressure dipping in adolescents with type 1 diabetes?
Absolute Event Rate: 11.6% vs 8.8%
p-value: p=< 0.0001
Using actual reported sleep time rather than preset times is necessary to accurately determine nocturnal systolic blood pressure dipping in adolescents with type 1 diabetes, and repeat ABPM is needed to confirm non-dipping status.

Supports using actual sleep time for nocturnal dipping assessment in T1D adolescents; leaves open effects on classification accuracy and outcomes.
Delaney et al. (2008) conducted an observational in Type 1 diabetes (n=98). Calculation by actual sleep time vs. Calculation by preset sleep time was evaluated on Decline in nocturnal systolic blood pressure (p=< 0.0001). Calculating nocturnal systolic blood pressure dip using actual sleep time resulted in a mean decline of 11.6% compared to 8.8% using a preset sleep time (P<0.0001).
