Associations Between Screen Exposure, Multidimensional Sleep Indicators, and Type 2 Diabetes: A Cross-sectional Study Using US National Survey Data

Excessive screen time is linked to elevated T2DM risk, particularly among females and individuals with sleep disorders. Longitudinal research is needed to assess causality and inform targeted interventions.
Study context
- Population
- US adults, NHANES 2007 to 2016; T2D defined by self-reported physician diagnosis
- Participants
- 23,023 adults
- Exposure
- High vs low screen exposure
- Outcome
- T2D (self-reported physician diagnosis)
Methodological detailssurvey-weighted multinomial logistic regression, multiple imputation by chained equations
- Survey-weighted multinomial logistic regression
- Multiple imputation by chained equations

As reported in the abstract
Observational data: associations, not effects.
Further findings
Sleep duration and T2D
- Sleep duration was not independently associated with T2D
Sleep disorders and T2D
- Sleep disorders linked to approximately twofold higher odds of T2D
- OR 2.21 (1.17, 4.18) (95% CI)
Screen–T2D association by subgroup
- Association stronger among females than males, with variation across sleep and racial/ethnic subgroups
