Table 2.

Odds ratios (95% CIs) for the associations of sleep duration (n = 2007) and insomnia symptoms (n = 2068) with a moderate to high aMed diet score at Exam 5

aMed score†	Sleep duration‡ (reference: <6 hr/night)			Insomnia symptoms§ (reference: no insomnia)
	6 to <7 hr/night n = 640	7–8 hr/night n = 532	>8 hr/night n = 226	Insomnia n = 739

^†Reference= low aMed score (<5).

^‡For sleep duration (ref <6 hr, n = 609).

^§For insomnia symptoms (ref no insomnia symptoms, n = 1329).

MODEL 1: adjusted for age, gender, race/ethnicity.

MODEL 2: adjusted for covariates in Model 1 as well as education.

MODEL 3: adjusted for covariates in Model 2 as well as cigarette smoking, intentional exercise, and total energy intake (Kcal/day).

MODEL 4: adjusted for covariates in Model 3 as well as, body mass index (Kg/m²), hypertension, diabetes, depressive symptoms (CESD score ≥ 16), AHI (continuous), insomnia symptoms, antidepressants and anti-psychotic medication.

In the models with insomnia symptoms as main predictor, we also adjusted for sleep duration (hr) in the last model.
