ABSTRACT: BACKGROUND: Insomnia symptoms are prevalent and associated with impaired health and well-being. However, scant research has investigated whether midlife insomnia symptoms are also associated with earlier retirement, thereby contributing to additional economic consequences. PARTICIPANTS AND METHODS: We analyzed data from a community-based sample of 1635 Wisconsin State employees (51.6% women) that were collected from 1988 until 2014. Study participants were asked about insomnia symptoms (difficulty getting to sleep, difficulty getting back to sleep, repeated nocturnal awakenings, and early morning awakenings) in midlife, with prospective follow-up questions about the specific reasons for retirement between 2010 and 2014. Using Cox proportional hazards models, we investigated longitudinal associations between insomnia symptom measures (ie, each individual insomnia symptom, any insomnia symptom, and number of insomnia symptoms) and rates of retirement. We also investigated reasons for retirement and the potentially mediating role of depression. RESULTS: For most of our insomnia measures, after adjusting for confounding variables, we did not find that insomnia symptoms at age 50 years were predictive of earlier overall retirement. One exception is that early morning awakening at age 50 years is associated with an increased rate of overall retirement (hazard ratio, 1.22; 95% confidence interval, 1.04-1.43). With regard to reason for retirement, we found that all measures of insomnia were associated with increased rates of retirement due to poor health/disability. For example, the presence of at least one insomnia symptom was associated with a hazard ratio of 1.38 (95% confidence interval, 1.13-1.68). We also found evidence that depressive symptoms mediate the association between insomnia symptoms and retirement due to poor health/disability. DISCUSSION: Our study finds an association between insomnia symptoms in midlife and retirement due to poor health/disability, whereas there is less compelling evidence between insomnia symptoms and retirement due to other reasons. Future research on insomnia should consider how earlier retirement affects the social and economic consequences of insomnia.

ABSTRACT: Whether insomnia, a known correlate of depression, predicts depression longitudinally warrants elucidation. The authors examined 555 Wisconsin Sleep Cohort Study participants aged 33-71 years without baseline depression or antidepressant use who completed baseline and follow-up overnight polysomnography and had complete questionnaire-based data on insomnia and depression for 1998-2006. Using Poisson regression, they estimated relative risks for depression (Zung scale score > or =50) at 4-year (average) follow-up according to baseline insomnia symptoms and polysomnographic markers. Twenty-six participants (4.7%) developed depression by follow-up. Having 3-4 insomnia symptoms versus none predicted depression risk (age-, sex-, and comorbidity-adjusted relative risk (RR) = 3.2, 95% confidence interval: 1.1, 9.6). After multiple adjustments, frequent difficulty falling asleep (RR = 5.3, 95% confidence interval: 1.1, 27.9) and polysomnographically assessed (upper or lower quartiles) sleep latency, continuity, and duration (RRs = 2.2-4.7; P's < or = 0.05) predicted depression. Graded trends (P-trend < or = 0.05) were observed with increasing number of symptoms, difficulty falling asleep, and difficulty returning to sleep. Given the small number of events using Zung > or =50 (depression cutpoint), a limitation that may bias multivariable estimates, continuous depression scores were analyzed; mean values were largely consistent with dichotomous findings. Insomnia symptoms or markers increased depression risk 2.2- to 5.3-fold. These results support prior findings based on self-reported insomnia and may extend similar conclusions to objective markers. Heightened recognition and treatment of insomnia may prevent subsequent depression.
