Table 5.

Odds Ratio and 95% CI of Multivariate models for each WOMAC hip pain adjusted for moderate to extreme hip pain while in bed for wake minutes >=90 after sleep onset

† Moderate to extreme WOMAC pain while	* Multivariate Model + pain while in Bed	** Pain while in Bed
Walking	1.28 (0.94–1.74)	1.45 (1.06–2.00)
Standing upright	1.41 (1.07–2.01)	1.37 (0.98–1.90)
Going down stairs	1.10 (0.81–1.49)	1.54 (1.12–2.14)

^†Models for pain while sitting or lying were not done due to high correlation with pain while in bed.

^*OR for each WOMAC activity adjusted for covariates and pain while in bed

^**OR for moderate to extreme pain in bed, when adjusted for covariates and each WOMAC hip pain activity.

Covariates: age, education years, BMI, back pain and recent worsening of arthritis, depression, fatigue, health status, anxiety, number of blocks walked for exercise and current use of benzodiazepines, opioids, or NSAIDs medications
