Social jet lag and (changes in) glycemic and metabolic control in people with type 2 diabetes

Brief summary: This cross-sectional and longitudinal study, nested in the Diabetes Care System cohort study from the West Friesland region of the Netherlands (n=990), assessed ‘social jet lag’ as the difference in midpoint of sleep in hours between weekdays and weekend days. Among working individuals with type 2 diabetes (T2D), this discordance between between social and biological rhythms (social jet lag) was associated with poor metabolic control. By contrast, among retired individuals, greater social jet lag was associated with better metabolic control.
