Popis: Introduction Many occupations consist of predominantly desk-based work, which leads to prolonged periods of sitting during the workday. Excessive periods of sedentary behavior could have a negative impact on health outcomes, including sleep. The purpose of this study was to characterize sleep health in a sample of sedentary desk-based workers. Methods This secondary analysis of baseline data from an ongoing clinical trial included 125 inactive adults with elevated, nonmedicated blood pressure and desk-based occupations (49.6% female, age=43.9±10.6 y, 85.6% White race, body mass index [BMI]=30.9±6.4 kg/m²). Sleep was assessed using validated questionnaires (e.g., Pittsburgh Sleep Quality Index [PSQI], Insomnia Severity Index [ISI]) and 7 nights of actigraphy. Six dimensions of sleep health (regularity, satisfaction, alertness, timing, efficiency, and duration) were categorized as “good” or “poor”; a composite score summed good sleep health dimensions on a scale of 0-6. Results The mean sleep health score was 4.7±1.1; 24.8% of participants met “good” criteria for all 6 sleep health dimensions. The most common “good” sleep health dimensions were efficiency (89.0%) and alertness (87.2%); the least common was regularity (60%). The mean PSQI score was 5.5±3.0, and 41.6% had poor sleep quality (PSQI >5); a trend was observed in adults with poor sleep quality to have lower sleep health (p=0.055). The mean ISI score was 7.1±4.7, and 40% had at least mild-severity insomnia symptoms (ISI ≥8); those with insomnia symptoms had significantly lower sleep health compared to those without insomnia symptoms (p=0.04). Sleep health was not significantly correlated with age, BMI, systolic blood pressure, diastolic blood pressure, mean arterial pressure, or mean daily sedentary behavior (each r≤ .08, p≥0.38) and did not differ between males and females (p=0.26). However, White adults had significantly better sleep health compared to their non-White counterparts (6.4% Black, 5.6% Asian, 2.4% other) (p Conclusion This sample of sedentary desk-based workers presented generally good sleep health. This warrants future investigations comparing adults with different levels of occupational activity and non-desk-based occupations to understand why highly sedentary behavior is associated with negative health outcomes.
