Computing chronodisruption: how to avoid potential chronobiological errors in epidemiological studies of shift work and cancer.

abstract：:Data on sleep or circadian abnormalities and metabolic disturbances in euthymic bipolar disorders are scarce and based on small sample sizes. The aim of this study was to explore the associations between sleep disturbances, chronotype and metabolic components in a large sample of euthymic patients with bipolar disorde...
