Feasibility of text message sleep assessment in african american and latino patients with type 2 diabetes

Abstract

Study Objectives: Text messaging (TM) may provide an inexpensive and convenient method for self-reported sleep assessment. This pilot study evaluated the feasibility of a TM sleep diary among a racial/ethnic minority population with uncontrolled type 2 diabetes. Methods: A convenience sample of 40 participants with uncontrolled type 2 diabetes was recruited. Participants wore an Actiwatch (Philips Spectrum Plus, Philips Respironics, Murrysville, Pennsylvania) for 7 consecutive days during both wake and sleep intervals and completed a daily TM sleep diary including 10 questions adapted from the Consensus Sleep Diary. The relationships between sleep measures from TMs and actigraphy were explored through Bland-Altman plots and correlations. Results:Of the 40 participants enrolled, 34 were African American and 6 were Latino. Themean age was 52.2 years (standard deviation = 8.2), and themean hemoglobin A1c was 9.0% (standard deviation = 1.5). All but 1 participant attempted to complete the TMsleep diary.With a maximumof 70 TM replies possible, the median number of responses per participant was 66 (interquartile range = 59.5-69). Actigraphy and TMmeasureswere related for total sleep time (median = 382 vs 393min, respectively [r =.71; P
