Adherence
Insomnia is a causal risk factor for type 2 diabetes, independent of BMI.
Prioritize treating insomnia as a medical risk factor for diabetes, not just a nuisance. If you have chronic sleep difficulties, address them with the same urgency as blood sugar management.
GoodSupportsHIGH confidence
Insomnia was identified as a novel risk factor (OR 1.17 [95% CI 1.11, 1.23]).
Why this rating
Mendelian randomization reduces confounding, but observational links remain strong.
