Circadian syndrome: a short read about a cohort study examining links between a proposed metabolic-plus-sleep/mood cluster and biological aging, showing why researchers are interested and what the article will discuss.

Key Takeaways
- Participants meeting circadian syndrome criteria showed mean biological ages about 1.6 years older than their chronological ages.
- Insulin resistance explained roughly half of the association between circadian syndrome and faster biological aging in exploratory analysis.
- The study used KDM-BA from routine labs in an observational Chinese cohort with largely self-reported sleep and mood measurements.
