Abstract

Background: The role that sleep patterns play in sepsis risk remains poorly understood.

Objectives: The objective was to evaluate the association between various sleep behaviours and the incidence of sepsis.

Methods: In this prospective cohort study, we analysed data from the UK Biobank (UKB). A total of 409,570 participants who were free of sepsis at baseline were included. We used a composite sleep score that considered the following five sleep behaviours: sleep chronotype, sleep duration, insomnia, snoring, and daytime sleepiness. Cox proportional hazards regression analysis was used to estimate the associations between healthy sleep scores and incident sepsis.

Results: During a mean follow-up of 13.54 years, 13,357 (3.26%) incident sepsis cases were recorded. Among the 409,570 participants with a mean age of 56.47 years, 184,124 (44.96%) were male; 9942 (2.43%) reported 0 to 1 of the five healthy sleep behaviours; 46,270 (11.30%) reported 2 behaviours; 115,272 (28.14%) reported 3 behaviours; 150,522 (36.75%) reported 4 behaviours; and 87,564 (21.38%) reported 5 behaviours at baseline. Each one-point increase in the sleep score was associated with a 5% lower risk of developing sepsis (hazard ratio (HR), 0.95; 95% confidence interval (CI), 0.93-0.97). Compared with a healthy sleep score of 0-1, for a sleep score of 5, the multivariate-adjusted HR (95% CI) for sepsis was 0.76 (0.69-0.83). In addition, we found that the negative correlation was stronger in participants who were aged < 60 years than in their older counterparts (p for interaction < 0.001). However, healthy sleep pattern was not associated with sepsis-related death and critical care admission.

Conclusions: Findings from this cohort study suggest that a healthy sleep pattern may reduce the risk of developing sepsis, particularly among younger individuals.
