A cohort study of 1,156 middle-aged and older Chinese adults found that inadequate sleep duration and late sleep onset were associated with increased glycemic variability. The findings suggest that poor sleep patterns may contribute to impaired glycemic control, highlighting their relevance for diabetes prevention. Researchers emphasized the need to consider sleep duration and timing in primary care. Limitations included self-reported sleep data and the need for further research in larger, more diverse populations.
