Table 4 Incident insomnia (T1-T2) as a risk factor for the persistence of anxiety and depression at 6-month follow-up (T2): Descriptive statistics, univariate logistic regression analyses and multivariate logistic regression analyses

From: Changes in insomnia as a risk factor for the incidence and persistence of anxiety and depression: a longitudinal community study

Health condition (T2) Changes in insomnia status [M (SD)]: Remission of health condition Changes in insomnia status [M (SD)]: Persistent health condition Unadjusted model: OR (95% CI) Adjusted model: OR (95% CI) a
Anxiety .210 (.48) .098 (.49) 0.62 (0.31–1.23) 0.68 (0.31–1.44)
Depression .192 (.44) .018 (.49) 0.44 (0.18–1.04) 0.30 (0.10–0.93)*
  1. Observe that a positive mean value for changes in insomnia status indicates remission over time at the group level; a negative value suggests incidence. CI Confidence interval, OR Odds ratio. * Significant at the .05 level. a Odds ratios adjusted for age, gender, civil status, vocational status, educational level, place of birth, anxiety (when depression was the dependent variable), and depression (when anxiety was the dependent variable)
