0589 A Systematic Review of Worksite Interventions and Their Impact on Employee Sleep

Abstract

Introduction: Workplace health interventions are a fixture of modern work environments. Although most worksite health programs target weight loss or physical activity, there is a growing focus on sleep as well. Methods: To examine the impact of worksite interventions on employee sleep duration, we conducted a systematic review according to PRISMA guidelines. We searched PubMed, Web of Knowledge, EMBASE, Scopus, and PsycINFO. The search included all published literature before August 2, 2017. Studies were independently reviewed for eligibility by two investigators who worked serially on data extraction with discrepancy adjudication by consensus. We included studies with: 1) participants ≥18 years old; (2) employee and worksite populations where a health-related intervention was administered; and (3) either objectively-or subjectively-measured sleep duration. Results: A total of 31 publications were included. Studies with multiple interventions were included separately for a total of 43 interventions in the analysis. There was a median (range) employee sample size of 37 (9 to 2,819). Industry sectors delivering interventions included healthcare/social assistance (32% of studies), office/administrative support (26%), protection services (10%), and financial information/ real estate (10%). The remaining industries included transportation, arts/media, education, and maintenance. Intervention targets included sleep hygiene (28% of studies), mindfulness/stress reduction (25%), healthy lifestyle (21%), schedule control (6%), light exposure (6%), shift timing (6%), and cognitive behavioral therapy (6%). Subjective (self-report) measures of sleep were collected in 74% of studies, while objective measures were collected in fewer studies (actigraphy: 23%; polysomnography: 3%). Conclusion: Worksite-based interventions hold promise for improving health among employee populations. In our review, the third pillar of health - sleep - is gaining attention in these models of health promotion. Common intervention targets included sleep hygiene and mindfulness/ stress reduction. While most of the studies used self-reported sleep duration, a minority did collect objective sleep duration.
