Hypothesis

Does self-reported sleep duration and quality affect the risk of developing diabetes in healthy workers in Japan?

Conclusion

Difficulty initiating sleep is associated with a higher risk of diabetes in relatively healthy Asian workers.

Supporting Evidence

230 cases of type 2 diabetes were reported over a median follow-up of 4.2 years.
61.3% of participants reported no difficulty initiating sleep.
Participants with high difficulty initiating sleep had a higher occurrence of diabetes in family history.

Takeaway

If you have trouble falling asleep, you might be more likely to get diabetes, even if you sleep enough hours.

Methodology

Data were analyzed from a cohort study using a Cox proportional hazard model to evaluate the association between sleep duration or quality and diabetes risk.
