Abstract
OBJECTIVE: To investigate associations between sleep duration and biomarkers of metabolic function among police officers. METHODS: Metabolic markers were measured using standardized methods and sleep duration was assessed from questionnaire data. Mean levels of leptin and adiponectin were assessed across five levels of sleep duration using ANCOVA and linear regression models. RESULTS: Police officers (n = 443) who reported an average of less than 5 hours and at least 8 hours of sleep had higher levels of leptin compared to those who reported an average of 5 to 7 hours of sleep. These associations were stronger and statistically significant among women, officers with BMI of 24.9 kg/m or less and smaller abdominal height (< 20 cm), and officers who primarily worked on the day shift. CONCLUSION: Short and long sleep duration were associated with higher leptin levels and may have implications for obesity-related conditions.
