One hundred and eleven youth with mental ill-health underwent systematic clinical, laboratory and actigraphy monitoring to report associations between 24-h sleep–wake patterns and cardiometabolic risk factors. Multiple linear regression analyses, controlling for medication usage and class, age and sex, found significant associations between: later sleep onset and BMI; standard variation (SV) in the sleep offset with both insulin values and the updated homeostatic model assessment of insulin resistance (HOMA2-IR) values; and the SV of the sleep midpoint with both poorer fasting insulin, and HOMA2-IR values. Further longitudinal research is required to determine the causative relationships between 24-h sleep–wake cycle patterns, and cardiometabolic outcomes.
