Abstract
OBJECTIVES: To investigate the associations of recreational screen time with risks of brain-related disorders (dementia, stroke, or Parkinson's disease) and neuroimaging features.</p>
DESIGN: Prospective cohort study.</p>
SETTING AND PARTICIPANTS: A total of 407,792 participants from the UK Biobank who were free of dementia, stroke, or Parkinson's disease at enrollment (2006-2010).</p>
METHODS: TV viewing and time spent using the computer were self-reported at baseline. Among a subsample of 40,692 participants, neuroimaging features were measured by magnetic resonance imaging in 2014. Data were analyzed using Cox proportional hazard models, restricted cubic spline, and general linear regression models.</p>
RESULTS: During a median follow-up of 12.6 years, 5227 incident dementia, 6822 stroke, and 2308 Parkinson's disease cases were identified. Compared with TV viewing >0-1 h/d, watching TV ≥5 h/d was associated with higher risks of dementia (hazard ratio [HR], 1.44; 95% confidence interval [CI], 1.28-1.62), stroke (HR, 1.12; 95% CI, 1.01-1.25), and Parkinson's disease (HR, 1.28; 95% CI, 1.06-1.54). Moreover, we observed inverse associations between TV viewing time and both gray matter volume and hippocampus volume (Ptrend <.001). However, we did not observe the significant associations between discretional computer use and brain-related disorders or neuroimaging features.</p>
CONCLUSIONS AND IMPLICATIONS: Our findings suggest that high TV viewing time is associated with increased risk of various brain-related disorders, highlighting recreational TV viewing could have an important impact on brain-related health.</p>
