Discretionary Screen Time and Progression From Prediabetes to Type 2 Diabetes: Mediating Roles of Sleep and the Triglyceride‐Glucose Index

Higher discretionary screen time was associated with an increased risk of type 2 diabetes among individuals with prediabetes, partly mediated by poor sleep and insulin resistance.
