Logistic Regressions Predicting Outcomes in Wave 4 by Sleep Disturbance

	Physical symptoms OR (CI)	ADL OR (CI)	Low quality of life OR (CI)
Sleep disturbance (reference: At W2 only)
None	1.00 (0.84–1.18)	0.87 (0.70–1.09)	0.82 (0.70–0.96)a
At W1 only	1.19 (0.96–1.49)	0.95 (0.72–1.25)	1.03 (0.84–1.26)
Chronic	1.32 (1.07–1.62)b	1.27 (1.00–1.61)a	1.26 (1.05–1.52)a

Note. Table presents odds ratio (OR) and 95% confidence interval (CI) in parentheses. ADL = difficulties in activities of daily living. Results are adjusted for geographic region, background characteristics, cognitive functioning, baseline of non-regressed outcomes and W1 and W2 levels of regressed outcomes
