Odds ratios (95% CIs) for the associations between insomnia symptoms with short sleep duration at Exam 5 and changes in aMed score between Exam 1 and Exam 5 (n = 1896)
| Changes in the aMed score from Exam 1 to Exam 5 | Insomnia with short sleep duration† n = 217 |
Insomnia without short sleep duration† n = 464 |
No insomnia with short sleep duration† n = 353 |

†Reference = No insomnia symptoms or short sleep duration (n = 862).
MODEL 1: adjusted for age, gender, and 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), antidepressants, and antipsychotic medication.
