Mentally active sedentary behavior is associated with cognitive function in humans (0.25 points, 95% CI 0.15-0.35, p < 0.001).
“Total mentally active sedentary behavior time and playing cards/mahjong time were significantly associated with global cognition (0.25 points [95% CI, 0.15-0.35], p < 0.001; 0.27 points [95% CI, 0.16-0.37], p < 0.001, respectively)”
