We explored the relationship between the Sleep Hygiene Practices Scale (SHPS) and sleep quality and sleep-related impairment in Black and Latinx adults with type 2 diabetes (T2DM).
Forty Black and Latinx adults with T2DM participated. Self-reported measures include the Pittsburg Sleep Quality Index (PSQI), Patient Reported Outcomes Measurement Information System (PROMIS) Sleep Disturbance (SD) and Sleep-Related Impairment (SRI) measures, and SHPS (domains include sleep schedule and timing, arousal-related behaviors, poor eating/drinking habits prior to sleep, and poor sleep environment).
SHPS Cronbach’s alpha coefficients were 0.58 (schedule), 0.78 (arousal), 0.29 (eating), 0.81 (environment) and 0.88 (overall for four domains). SHPS scores correlated with PSQI (Pearson correlation r = 0.67, 95% CI [0.44, 0.81], PROMIS-SD (r = 0.61 [0.36–0.77]), and PROMIS-SRI (r = 0.43, [0.13–0.65]). There remained a significant relationship between sleep hygiene and both sleep quality and sleep-related impairment adjusting for hemoglobin A1c, age, and body mass index in regression models.
We observed moderate correlations between sleep quality and sleep-related impairment with sleep hygiene using the SHPS in Black and Latinx adults with T2DM.
•The American Diabetes Association recommends people with type 2 diabetes have assessments to identify sleep health issues.•The Sleep Hygiene Practices Scale is used to evaluate sleep habits, daily activities affecting sleep, and sleep environments.•SHPS has moderate correlations with sleep quality and sleep-related impairment in Black and Latino adults with type 2 diabetes.•The relationship between SHPS, sleep quality, and sleep-related impairment remained after adjusting for HbA1c, age, and BMI.
