Abstract
The association of mortality risk and insomnia disorder with daytime impairments has been plausible. The purpose of this study was to evaluate the strength of evidence for this relationship. We performed a comprehensive literature search for clinical Cohort trials including annual cumulative time-to-event data that evaluated the risk of mortality in insomnia disorder patients with daytime impairments. We used pooled hazard ratio (HR) as the main outcome measure and Kaplan-Meier survive curve to display outcome measures. The weighted cumulative mortality of 4.5% for patients with insomnia disorder was higher than that of 2.6% for those without insomnia (p<0.001). Higher risk of mortality presented in patients with insomnia disorder when compared to those without insomnia (HR = 1.66, 95% CI = 1.25–2.19, p<0.001). Patients with duration of more than 10 years were at a greater risk of annual cumulative mortality (R2 = 0.891, p<0.001). Insomnia disorder with daytime impairments increased the risk of mortality, and patients with duration of more than 10 years were at a greater risk of annual cumulative mortality.
