Adjusted Logistic Regression Models Predicting Sleep Impairment

	HD	Subclinical HD
Poor Sleep Quality (Subjective)	2.07 (1.83–2.34)	1.66 (1.46–1.89)
Increased Sleep Latency	1.59 (1.40–1.81)	1.34 (1.17–1.53)
Decreased Sleep Duration	1.93 (1.66–2.24)	1.64 (1.40–1.92)
Impaired Sleep Efficiency	1.72 (1.50–1.97)	1.44 (1.24–1.66)
Increased Sleep Disturbances	2.15 (1.91–2.43)	1.71 (1.51–1.93)
Increased Use of Sleep Medication	1.10 (0.97–1.26)	1.07 (0.94–1.23)
Increased Daytime Dysfunction	5.84 (5.12–6.65)	3.01 (2.62–3.46)
“Poor” Sleep (PSQI Total Score >13)	2.75 (2.26–3.35)	1.86 (1.48–2.34)

Values are adjusted odds ratio (95% confidence interval). Separate logistic regression models adjusted for gender, age, race, educational attainment, body mass index, self-reported lifetime psychiatric conditions (major depressive disorder, anxiety disorders), and self-reported sleep apnea.

HD, hoarding disorder; PSQI, Pittsburgh Sleep Quality Index.
