Memory

downin humans1

1 study
  1. Leisure screen time impairs memory in humans (β=‐0.07; 95%CI: ‐0.11, ‐0.02).

    “Leisure screen time was associated with more rapid memory decline (β=‐0.07; 95%CI: ‐0.11, ‐0.02).”

Telomere length

downin silico1

1 study
  1. Leisure screen time decreases telomere length in silico (β = -0.04, P = 4.95E-06).

    “Univariable MR analysis indicated significant associations of LST with telomere length (β = - 0.04, P = 4.95E-06)”

Frailty

upin silico1OR 1.157

1 study
  1. Leisure screen time raises the risk of frailty in silico (OR = 1.157, 95% CI: 1.118-1.197).

    “Higher genetically predicted LST was associated with a higher risk of frailty after radial MR outlier correction (IVW OR = 1.157, 95% CI: 1.118-1.197, P = 5.42e-17)”
